                            1.0  INTRODUCTION
                   1.1   DESCRIPTION OF PROPOSED PROJECT
CF  Industries,  Inc.  (CF)  currently owns  and  operates  phosphate mining
and beneficiation  facilities,  known as the  Hardee Phosphate Complex I
Mine,  in northwest Hardee County,  Florida.   These existing operations
were  initiated  in  1978  and are planned to  continue through 1997.
Approximately one million tons per year  of  phosphate  rock are  currently
being  processed  at this mine.

CF  is  proposing  to develop and operate a new phosphate mine and benefi-
ciation facilities on a 14,994-acre site in  Hardee County just south of
its existing mining  operation.  The proposed operation will be referred
to  as  the Hardee Phosphate Complex II Mine.   Figure 1.1-1 shows the
general location of  CF's  existing  mine and  the proposed mine.   The
proposed mine site is located  east of Horse  Creek and  south of State
Road 62.  The site is rectangular  in shape,  extending  about 10 miles in
a east-west direction and about  2.5 miles north-south.   Figure 1.1-2
presents a more detailed  view  of the proposed mine site,  including  CF's
planned locations for the beneficiation  plant and the  300-acre site
planned for the  initial clay settling area.

According to CF's proposed Plan  of Action, construction of the bene-
ficiation plant, adjoining storage and settling areas,  and initial
clearing and site preparation  activities at  the proposed  mine  are
scheduled to begin in 1988, with mining  commencing in  1989.  The mining
operations will be designed to produce approximately 2 million tons per
year of phosphate rock  during  the  first  phase of mining,  utilizing  a
single dragline operation.  During the second phase (beginning about
1997) and for the remainder of the projected 27-year life of the mine,
the operation will be expanded to  4 million  tons  per year with the
addition of a second dragline.   The phosphate rock produced from  this
new facility would replace CF's  rock supply  currently  provided by
another phosphate mining  company under two  long-term contracts with
expiration dates in  1984  and 1988,  respectively.

 The  proposed  operations will involve mining and processing methods which
 are  commonly  used in the extraction and processing of phosphate ore  in
 the  Central Florida Land-Pebble Phosphate District.  Major phases of  the
 proposed  operation will include:
      1.   Clearing and  preparing the site for operations and constructing
          the  processing plant,  initial settling areas, well fields,
          water  and wastewater control and recirculation systems,
          transportation systems,  and other ancillary operations;
      2.   Extracting the phosphate ore-bearing matrix by electric-powered
          dragline;
      3.   Transporting  the matrix to the central processing plant;
      A.   Physically separating  the phosphate,ore from the sand and clay
          wastes;
      5.   Disposing of  the sand  and clay wastes;
      6.   Shipping the  phosphate ore from the facility by rail; and
      7.   Reclaiming or restoring the disturbed areas.

                   1.2   REQUIREMENT FOR EIS PREPARATION
 CF plans  to locate and design the proposed operations for the proposed
 mine  in such  a  manner  that  the  process wastewater generated from mine
 dewatering, phosphate  beneficiation, sand and clay waste settling,
 surface water runoff,  and other processes will  be contained in an
 extensive recirculation system.  This system is intended to provide  for
 maximum reuse of  water within the operation in  order to minimize the
 withdrawal of ground water  for  use in the operations as well  as minimize
 the discharge of  process waters from the site.   However, during certain
 periods of the  operation or times of the year,  CF anticipates that some
 of the recirculating water  will need to be discharged from this system
 to nearby wetlands  and/or surface waters.

 The U.S.  Environmental  Protection Agency (EPA),  Region IV,  has deter-
mined that due  to  these  wastewater discharges,  the  proposed CF mining
operations at  the Hardee Phosphate Complex II mine  will  constitute a
"new source" discharge  facility under  Section 306 of the Federal Clean

-------
Water Act  of  1977  (FCWA),  as  amended.   As  a new source facility,  the
proposed CF operations  are  subject  to  the  National  Pollutant  Discharge
Elimination System (NPDES)  new  source  effluent  limitations  and  permit
requirements  under Section  402  of  the  FCWA.   Also,  it  is  possible  that
the proposed  operations will  be subject to the  dredge  and fill  permit
requirements  of the U.S. Army Corps  of Engineers (COE) under  Section 404
of the FCWA.  The  issuance  of a NPDES  permit by EPA and/or  a  dredge and
fill permit by COE may  represent major federal  actions,  significantly
affecting  the quality of the  human  environment.  Therefore, prior  to
issuance,  permit approvals  may  be  subject  to the requirements of  the
National Environmental  Policy Act  of 1969  (NEPA) requiring  preparation
of a detailed Environmental Impact  Statement (EIS).

EPA Region IV has  determined  that  the  proposed  CF phosphate mining and
processing operations represents a  new source and major  federal action
significantly affecting the quality  of the human environment  under NEPA.
Therefore, as a prerequisite  to granting the NPDES  permits, a detailed,
site-specific EIS  on the proposed CF phosphate  raining  operation in
Hardee County, Florida, must  be prepared.

EPA Region IV accepted  the  lead agency responsibility  for preparation  of
this Environmental Impact Statement.

The EIS document is prepared  as an  assessment of the impacts  of the
proposed mining operation.  The EIS  includes an investigation and
evaluation of the  environmental issues and alternatives  associated with
the proposed  operation.  In this process,  the EIS provides a  vehicle for
public and agency  involvement and establishes a framework for assessment
of project-related issues.  The result is  a  logical, orderly
decision-making process upon  which EPA and other regulatory agencies can
base their decisions regarding  the  issuance  of  applicable permits  and
approvals.

In order to expedite the EIS  preparation process, EPA  and CF  elected to
comply with the NEPA requirements by a "Third Party" consultant

-------
arrangement.  Under  this  arrangement,  EPA (as  lead  federal  agency) and
CF (as applicant  for  federal  permit  approval)  entered into  a Memorandum
of Understanding  (MOU) whereby  CF  engaged and  retained  at  its expense,
an independent Third  Party  consultant  acceptable to EPA,  for the
preparation of the detailed EIS.   EPA  retained responsibility for
content of  the EIS and therefore,  direct  supervision, review, and
approval of all work  performed  by  the  Third Party consultant.  Also,
under this  arrangement, other concerned  regulatory  agencies (such as
COE) served as cooperating  agencies, reviewing and  commenting on the  EIS
to EPA as the lead agency.

Environmental Science and Engineering,  Inc. (ESE) was approved by EPA to
serve as CF's Third Party consultant.  ESE's  role involved  the assimila-
tion and analysis of  all  environmental  data for the EIS.  All work
products generated by ESE were  submitted  simultaneously  to  EPA and CF
for review.  Any  technical  changes in  these work products  requested by
CF required EPA approval.   Any  technical  direction  given  to ESE by EPA
which was beyond  the  scope  of work defined  in  ESE's contract with CF  had
to be approved by CF  prior  to commencing  of work efforts.   During the
project, EPA, CF, and ESE interacted  freely with one another as a team.

              1.3  STATUS OF  OTHER PERMITTING  REQUIREMENTS
In addition to the previously discussed  requirements, CF was responsible
for performing environmental  studies  for  fulfilling certain other
federal, state, and  local requirements  and  conditions needed to obtain
applicable  permits and regulatory  approvals,  prior  to initiation of the
proposed operations  at the  Hardee  Phosphate Complex II mine.

CF iniciated the  environmental  permitting program for its Hardee County
phosphate operations  in the mid-1970s  by  conducting studies on both the
existing mine and proposed  mine sites.  These  studies involved mining,
reclamation, hydrology, geology, air  quality,  radiation,  aquatic and
terrestrial ecology, water  quality,  socioeconomics,  and  archaeology.   To
date, the results of  these  studies have  been  used primarily by
                               1-6

-------
 CF Industries to fulfill  the following three key regulatory
 requirements:
      1.   Consumptive Use  Permit—Approved by the Southwest Florida Water
          Management District (SWFWMD)  on March 10, 1976;
      2.   Application for  Development Approval/Development of Regional
          Impact  (ADA/DRI)—Approved Development Order issued by Hardee
          County, June 30, 1976; and
      3.   Mineral Extraction Permit  and Zoning Variance
          Approval—Approved by Hardee  County, June 30, 1976.

 These previously completed  requirements,  which have received favorable
 governmental approvals,  involved all the lands which CF owned and
 planned  to  mine  in Hardee County.   Therefore, the regulatory approvals
 of these three  requirements covered both the existing mine and the
 proposed mine site.   The  following  sections  briefly describe these
 previously  completed regulatory requirements.

 1.3.1  CONSUMPTIVE USE OF WATER PERMIT
 Under the Florida Water Resources Act  of  1972,  Chapter 373,  Florida
 Statutes, regional  water  management  districts are charged with the
 responsibility of regulating water  usage  in  the state.  The  regional
 district  with jurisdiction  in  the proposed mining area is Southwest
 Florida  Water Management  District (SWFWMD).   Under Chapter 16J-2,
 Florida  Administrative Code  (FAC),  SWFWMD requires  a permit  for the
 consumptive use  of water  if  the withdrawal during any single day is to
 exceed one  million  gallons.   Since  the CF mining  operations  required
 water amounts in excess of  these threshold limits,  a SWFWMD  Consumptive
 Use of Water  Permit  was required.

 In 1975,  CF conducted extensive aquifer  pump tests  on the proposed site
 to determine  the  effects  of  an  average annual withdrawal  of  15.74
million  gallons  of  water  per day from  four production wells  and a
 surface  reservoir,  and a  maximum daily withdrawal  of 20.20 million
gallons  per  day.
                            1-7

-------
 Based on the results of these studies, CF prepared and submitted an
 Application for Consumptive Use permit to SWFWMD on January 2, 1976.
 After reviewing the application, SWFWMD granted CF a permit for the
 consumptive use of ground and surface water in the amount cited above,
 subject  to  certain terms and conditions.   Thus, CF fulfilled the
 requirements and obtained a Consumptive Use Permit for SWFWMD for its
 operations.

 1.3.2 APPLICATION FOR DEVELOPMENT APPROVAL/DEVELOPMENT OF REGIONAL
       IMPACT
According  to  Rule  22F-2.06,  FAC,  if a mining operation will disturb more
than  100 acres  per  year  or consume more than 3 million gallons per day
(mgd) of water,  the operation will be presumed to be a Development of
Regional Impact  (DRl).   In addition,  under Chapter 380, Florida
Statutes,  the developer  proposing to  construct the DRI project must
prepare an Application  for Development Approval (ADA) which includes a
comprehensive assessment  of  the regional impacts that the proposed
development will have on  the  environment.   This DRI application is
reviewed,  and recommendations or  approvals are made by various state,
regional,  and local  agencies.   However,  the DRI application must  be
ultimately approved  by  the local  government (usually the county)  prior
to beginning  construction.

The CF mining operations  required preparation of an ADA/DRI which needed
approval of Hardee  County.  The regional planning council responsible
for reviewing and making  recommendations to the county concerning the
accuracy and  sufficiency  of the information in the ADA/DRI and its
approval was  the Central  Florida  Regional  Planning Council (CFRPC).

As part of its environmental  permitting  program,  CF had an ADA/DRI with
special studies appendices prepared which  was submitted to Hardee County
on June 30, 1976.  After  review of  the ADA/DRI,  Hardee County  adopted
Development Orders which  approved the  CF application,  subject  to  certain
conditions.  Thus,  CF fulfilled.the requirements o£ the ADA/DRI from
Hardee County.
                            1-8

-------
1.3.3  HARDEE COUNTY MINING AND  EARTH MOVING ORDINANCE AND ZONING
       VARIANCE
Under County Ordinance No. 73-6,  Amendment  No.  1,  Hardee County requires
that a permit for Mineral Extraction  be  obtained  for proposed raining
operations within its boundaries.   In addition,  the county requires a
zoning variance be  applied for and  obtained to  classify proposed mine
lands as M-l, Mining and Earth Moving District.

In order to fulfill the  requirements  of  the mining ordinance, CF had a
Mining and Reclamation Master Plan  prepared in  conjunction with the
ADA/DRI.  The master plan was submitted  to  Hardee  County with the
ADA/DRI on June 30, 1976,  for review  and was approved by the county
subject to the same conditions as  the ADA/DRI.   CF also applied for and
was granted the necessary  zoning variance by the  county for its
phosphate mining operations.

               1.4  THE  SUPPLEMENTAL  INFORMATION  DOCUMENT
Primary inputs for  EIS preparation  include  (1)  the environmental data
collected and the analyses performed  in  conjunction with previous
permitting efforts  for the existing and  proposed  CF mining operations,
and (2) the data from CF's environmental monitoring program at the mine
sites in Hardee County.  ESE was  responsible for verifying the technical
quality of these data prior to use  in the EIS.   In addition, since CF
modified the mining and  reclamation plans which were included in the
ADA/DRI and Master Mine Plan, ESE was responsible  for reassessing and/or
updating the potential impacts of Che proposed  operations as well as
feasible alternatives to the proposed operations.

This Supplemental Information Document (SID) has  been prepared to
supplement the Environmental Impact Statement for  CF's Hardee Phosphate
Complex II mine.  It includes, by technical discipline,  findings of fact
and substantive data and analyses to  support the  evaluations and impact
assessments within  the KIS.  This SID contains  the technical data base
developed from field observations,  laboratory investigations,
                             1-9

-------
mathematical models  and  analyses,  and  previously existing  data.   The  SID
includes  a description of  the  Proposed Action and data for the  following
technical disciplines:
     • Air Resources
     • Geotechnical  Resources
     • Radiation
     • Ground Water
     • Surface Water
     • Aquatic Ecology

                   2.0  CF  INDUSTRIES'  PROPOSED ACTION
                     2.1   DRAGLINE  MINING OPERATION
2.1.1  DEPOSIT GEOLOGY
The Ore-Bearing Zone (Matrix)  on  CF Industries'  Hardee County tract
constitutes part of  the Bone Valley and Hawthorn Formations,  deposited
between 2-15 million years ago when shallow seas inundated much of the
Florida Peninsula  during  the Miocene and Pliocene epochs.   The matrix,
averaging 23.7 feet  in thickness,  is covered by an overburden of quartz
sand, clay, gravel,  and a  thin layer of topsoil.  This overburden has an
average thickness  of 15.4  feet.   An underlying bedrock unit is composed
of various limestones overlaid by bedclays.   The matrix variey both in
composition and in distribution over the tract,  typical for phosphorite
ore bodies in Hardee County.

The ore zone is characterized  by  phosphate pebbles and fine phosphatic
sand dispersed in  a nonphosphatic,  sandy clay.   The percentage break-
down of this zone  is illustrated  in Table 2.1.1-1.   Only about
20 percent phosphate product is present in the  matrix material,  the
remainder being regarded  as waste materials.   The primary  phosphate
mineral is collophane, a calcium magnesium fluorapatite that  contains
small amounts of other minerals.

In comparison to the phosphate ore  being rained  in Polk and Hillsborough
Counties, CF Industries' ore is of  lower grade  and has finer  sized
particles.  However, both  the  phosphate product  and the clay/sand by-
product content of this ore are typical of ore  deposits found throughout
the Southern District.  The total reserves of phosphate rock  product
which would be recoverable by  CF  Industries  in  this project amount to
97.0 million short tons.

2.1.2  LAND CLEARING
Early construction,  including  receipt  and erection of the  dragline, was
approved by the EPA.  Clearing of existing vegetation for  this approved
activity was accomplished  as follows:

     • Dragline  assembly  areas;
     • Power line (construction  power);
     • Partial rail  spur;  and
     • Access  road.

Prior to mining,  land  clearing  will  be  required  for  construction of the
initial clay settling  areas,  the  initial  mining  areas,  and  the  powerline
and pipeline right-of-ways.   Land  clearing  for  the  initial  settling
areas will begin as  near  to  the start of  construction  as  feasibly
possible and will require  approximately 460 acres of clearing.   Two
hundred thirty-two (232)  acres  are planned  for  the  first  year of mining;
however, CF expects  to clear only  80 acres  initially,  most  of which will
be completed prior to  construction of the initial settling  areas
(Figure 2.1-1).

As mining progresses,  acreage will gradually be  cleared ahead of the
actual mining operation.   The average acreage being  cleared  at  any  given
time will be about 80  acres,  but  this figure can vary  depending on  the
type of land to  be cleared and  the time of  year.  During  the dry season,
clearing will generally be limited to preparing  3 to 6  months of work
area in advance  of the dragline, unless the area to  be  mined is heavily
vegetated.  In the case of pine flatwoods-palraetto  rangeland, clearing
must be initiated several months prior  to mining to  allow complete
removal of any woody material that might  interfere with the  mining
process.  In such areas,  it  will also be  desirable to  clear  sufficient
land for two to  three  months mining  prior to the onset  of the rainy
season.   When necessary, vegetation  on  land to be rained will be burned.
Such open burning would be conducted according  to the  applicable rules
and regulations  (Florida Administrative Code, Chapter  17-5,  Open Burning
and Forest Protection  Fires; and Chapter  51-2, Rural Open Burning).
These rules specify that:
     • Open burning be conducted  in  a manner, under  conditions, and
       within certain  periods that will reduce or eliminate  the
       deleterious effect  of  air pollution  caused by open burning.

     • Open burning may  be  conducted  only between the hours of 9:00 a.m.
       and one hour before  sunset,  or upon direct permission of the
       Division of Forestry for  other hours of the day.
     • The size, moisture content,  and composition of the refuse piles
       shall be such  so  as  to  minimize air pollution and ensure that all
       burning will be completed within the allowable time period.

2.1.3  PRESERVED AREAS
The areas to be preserved from mining occupy approximately 69 acres and
consist of all but 2  acres  of  the wetlands designated as Category I-A by
the EPA.  These proposed preserved  wetlands are located  in the far
western portion of the site and  are contiguous with Horse Creek
(Figure 2.1-2).  The  two acres of Category 1-A wetlands  to be disturbed
will bvi needed for the proposed  dragline  crossing (see Section 2.1.4).
Category 1-A wetlands are mainstem  stream wetlands that  are considered
by the EPA to provide important  environmental  functions  and which should
be preserved and .protected  from  mining.

In addition to the Category I-A  wetlands,  there are approximately
695 acres of Category I-C and  I-D wetlands on  the site.   These are  head-
water and special concern wetlands  that  are also considered by the  EPA
as worthy of preservation and  protection.   However, the  EPA recognizes
the possibility that  reclamation technology may proceed  to the extent
that fully functional wetlands may  be restored.  The Florida phosphate
industry, including CF Industries,  is  currently working  on approximately
35 wetland reclamation projects  (Florida  Institute of Phosphate
Research, I983a).  CF Industries believes  that these ongoing projects,
together with CF's proposed experimental  revegetation program on an
existing sand/clay mix disposal  area,  will demonstrate that important
functional roles of wetlands can be replaced by reclamation.

Therefore,  CF Industries has included  the  Category I-C and I-D wetlands
within the area to be disturbed  by  mining  activities. Although the mine
                                2-5

plan and waste disposal plan were developed  to  include  all  Category I-C
and I-D wetlands, CF understands  the  EPA's  position  on  the  raining of
these wetlands.  Mining will not be allowed  within the  boundaries of any
of  the Category I wetlands  unless and until  the EPA  reconsiders  the
categorization or value of  these wetlands based upon  the  proven  recrea-
tion of functional  hardwood  swamp communities  and  large wetland  systems.
CF believes that it can successfully  demonstrate a viable,  functional
restoration program sufficient  to receive EPA  approval  to mine  these
areas in the future.  A description of  the EPA's wetland  categorization
system, as applied  to the wetlands on-site,  is  presented  in
Section 9.1.2.3.

The Category I-A wetlands that  are to be preserved will also  be
protected from the  indirect effects of  mining.   A perimeter ditch will
be constructed around all preserved wetlands when  adjacent  lands are
being mined.  The water level in this ditch  will be maintained at or
above the average water table elevation, which  should prevent potential
drawdown of the water table within the  wetland  (Figure  2.1-3.).

The mined land adjacent to  these preserved wetlands  will  be reclaimed to
land-and-lakes (see Section 2.6.2.3)  by grading and contouring the
remaining spoil piles.  This type of  reclamation can  be completed in a
short period of time (approximately two years),  which will  also  reduce
the potential effects of mining.

2.1.4  DRAGLINE CROSSINGS
In mine year 20, the dragline mining  the west  tract  will  cross the Horse
Creek Category I-A  area.  This  dragline relocation will require  an
access corridor across two  areas of Horse Creek, located  in Town-
ship 33S,  Range 23E, Section 32 (Figures 2.1-4A and  2.1-4B).  The corri-
dor will be constructed during  the dry  season  when Horse  Creek  is likely
to be at minimum or no flow conditions. Topography  specific  to  this
area requires minimal grading to establish  the  corridor.  Approximately
two acres will be disturbed for the planned  corridor.

The corridor will be the only link between  the  east  and west  side of
Horse Creek during  all phases of mining activities,  including
                                 2-7

reclamation.   It will  contain  a double-cased matrix pipeline and
hydraulic water pipeline  (Figures 2.1-4A and 2.1-4B) necessary for
mining and  ore transportation.   The  double-cased matrix pipeline will
extend beyond  the  corridor  limits in the east-west direction to protect
the area against any accidental leakage, thus protecting the "preserved
area" of Horse Creek.   In addition to the double-cased matrix pipeline,
a berm will be constructed  on  both edges of the corridor and grasses
will be established on all  graded or constructed areas to prevent
erosion and turbid runoff into  the creek.  The corridor will be main-
tained and  monitored by CF  until the final dragline crossing in mine
year 21 and the removal of  the  pipelines and reclamation activities are
completed on the west  side  of  Horse  Creek.

After the dragline has  returned over the stream and the crossing loca-
tion is no  longer  needed, the  fill will  be removed and the area will be
graded to approximately original elevations.  A layer of organic soil
borrowed from  a wetland to  be  mined  will be spread over the area after
final grading  to encourage  natural revegetation.

A short-lived herbaceous  species such as rye or millet will be planted
over the reclaimed area to  stabilize the soils and minimize erosion.
Where wooded wetland systems have been disturbed,  native and locally
grown trees will be planted at  a density of a least 400 seedlings per
acre.  Trees to be planted  will include  species such as red maple,
sweetgum, sweet bay, laurel oak,  and water oak.  Where herbaceous wet-
land systems have  been  disturbed,  the organic soil layer is expected to
provide revegetation similar to the  disturbed marshes.  The likelihood
of successful revegetation  in  the reclaimed area is high because of the
existing floodplain forest  immediately adjacent upstream of the proposed
stream crossing.  This  existing floodplain forest will provide a good
seed source for a wide  variety  of wetland plant species.

2.1.5  PHOSPHATE MINING
Within the central Florida  phosphate industry, the conventional
procedure for mining phosphate  ore consists of stripping away the
                               2-11

-------
 overburden and  removing the phosphate matrix with draglines.  The
 CF Hardee Phosphate Complex II project would initially employ a single
 dragline  with bucket  capacity of 55 cubic yards.  In mining year 8, a
 second  dragline of similar capacity would be added to provide additional
 excavation capabilities to support an expanded  beneficiation facility.

 Typical dragline operations include the development of a series of
 mining  cuts with the  overburden from the initial cut being placed on
 adjacent  mine land.   As successive cuts are made, each varying from
 250 to  300 feet wide  and 50 to 70 feet deep, overburden material is
 placed  in adjacent cuts previously mined.  Leach zone material would be
 placed  near the base  of the mining cut, then covered with overburden to
 minimize  any naturally occurring radiation from uranium concentrations.
 The ore is placed  in  a matrix well,  where it is slurrified for transport
 to the  beneficiation  plant.  As the mining operation proceeds, the
 matrix  well and ore transport  equipment are advanced along the direction
 of mining  with  the dragline.   Electrical power  for the operation of the
 dragline  and the matrix slurry equipment is provided by portable cables
 extended  from a pole  line  approximately 2,000 to 3,000 feet to this
 equipment.

 The proposed mining operations would result in  an average annual excava-
 tion of approximately 12.3 million cubic yards  of overburden and 16.2
 million cubic yards of phosphate matrix when two draglines are in
 operation.   The average density (dry basis) of  these materials is
 approximately 1.25 short tons/cubic  yard.   In a drained condition, they
 would contain about 75 to  85  percent solids.

During  the planned mine life  of 27 years,  the proposed mine operation
 would disturb approximately 14,925 acres or 99  percent of the  site.
Table 2.1.5-1 shows the acreage of each vegetation type to be  disturbed
by  the mining operation.

 The planned sequence of raining is illustrated in Figure  2.1-5.  Existing
 land use patterns would continue on reserve  land until those  lands  are
 scheduled for raining.  Approximately 69 acres would remain undisturbed.
 CF's raining sequence has been developed through the use  of a  computer
 model which simulates the mining and processing of the entire mineable
 deposit on an annual basis.  The base data for this program came  from
 the prospect drilling results and the preliminary design of the raining
 and processing equipment.  The dragline would follow a sequence which
 balances production and grade requirements and facilitates water
 recirculation, waste disposal and reclamation activities.  If production
 and sales requirements change, the length of the mine operation may also
 be  changed.

 2.1.6  DRAINAGE BASIN MINING SEQUENCE
 Mining and reclamation events in each system are described in the
 following discussion.  Mining years  and reclamation features are given.
 The sequencing of mining activities  is  shown in Figure 2.1-5.

 2.1.6.1  DOE BRANCH
 The plant site and initial  settling  area (ISA) lie partly in the Doe
 Branch watershed.   Construction of the  plant  site  and ISA will impact
 approximately 5 percent of  the Doe Branch watershed for the life of the
 mine.   Most  of this area will be  reclaimed to the  Doe Branch watershed
 at  the completion of mining.

 Mining in the watershed occurs from  year 1 through year 24.   At no time
 during the mining  will  there  be less  than 45  percent  of the  watershed
 area in an undisturbed  or reclaimed  state.

 The  first  year  of  mining will begin  just  west of the  main stream of Doe
 Branch and proceed west. In  year 2  the  dragline will  cross  Doe Branch
 and  begin  mining  in Section 21.   Reclamation  of  a  stream  course will be
undertaken in the  area  mined  just west  of  the main stream.   The
                                   2-14

 reclamation  will  be complete in time to receive the flow from the main
 stream before it  is scheduled for mining in the latter part of year 3.
 The  upstream area of Doe Branch in Section 33 will serve as a seed
 source for  the reclaimed stream course until the upstream area is mined
 in year 9.   The area immediately downstream of the reclaimed stream
 course will  serve as a buffer to minimize impacts of mining and reclama-
 tion activities.   This downstream segment is not scheduled for raining
 until  year  24.

 From year 3  mining will progress to the east until Section 27 is mined
 in year 6.   At  this time,  the drdgline will move to the western half of
 Section 32 and  begin mining to the east.  The dragline will leave the
 Doe  Branch watershed in year 14, and again in year 18 before returning
 to Section 21 in  year 24 to complete mining in the Doe Branch watershed
 and  the east  half of Complex II.

 The  majority of the watershed will be reclaimed using sand/clay mix
 technology (see Section 2.4).  The first sand/clay mix area will be
 reclaimed in year 10 and every one to two years after that another sand/
 clay area will  be reclaimed in the watershed.   The sand/clay areas will
 include wetland reclamation at the downstream end of each area.   At the
 completion of reclamation,  the wetland acres that existed before mining
 will exist after  reclamation.

When mining  in  the watershed is complete in year 24,  approximately 75
 percent  of the  Doe Branch watershed will have  been reclaimed.   By year
 29,  all but  5 percent of the watershed (area occupied by the ISA and
 plant  site)  will  have been  reclaimed.  Total acreage in the Doe  Branch
watershed following reclamation will be approximately 4,708 acres.

 2.1.6.2  PLUNDER  BRANCH
The  major portion of the Plunder Branch watershed will be mined  from
year 14  through year 23.  A small  part of the  watershed will  be  mined in
years  5  and 6.
                                 2-16

-------
The first mining  in  the  stream  course  occurs  in year 14.   The west fork
of Plunder Branch  will  be  mined by  year 17.   Reclamation  of approxi-
mately 220 acres of  the  watershed in Sections 23 and 26 will be
reclaimed using  sand  tailings  and overburden.  This  reclamation will be
completed by year  19  and will  include  wetland acreage which will serve
as a buffer to downstream  areas as  runoff from the reclaimed sand/clay
mix areas discharges  to  the  system.

The majority of  the Plunder  Branch  watershed  acreage upstream of the
aforementioned 220 acres will be  reclaimed  using the sand/clay mix
technique.  The majority of  the wetland acreage associated with the
watershed will be  reclaimed  as  a  part  of the  sand/clay reclamation.

In year 23, when  the  watershed  is mined out,  all but 14 percent of the
watershed on-site will be  out of  service.  However,  due to the sand/clay
reclamation, by  year  26  this percentage will  increase to  45 percent.  By
year 29, there will be  72  percent of the watershed contributing to the
Plunder Branch system.

When reclamation  is  complete,  there  will be  approximately 5 percent less
acreage than existed  in  the  pre-mining watershed,  or a total of 2,266
acres.

2.1.6.3  COON'S BAY  BRANCH
The 259 acres of  the  Coon's  Bay Branch watershed on-site  will be mined
in years 19 and 20.   This  watershed  will be  reclaimed using sand tail-
ings and overburden.  There  will  be  a  total  of 188 acres  reclaimed in
the watershed.  Reclamation  will be  complete  by year 23.

2.1.6.4  TROUBLESOME  CREEK
Although there is  no  stream, course  on-site  in the Troublesome Creek
watershed, there is approximately 550  acres  of watershed  area.  The
initial settling area will occupy the  majority of the 234 acres of this
watershed which lies  west  of the  Seaboard Coast Line Railroad.  The
                                 2-17

-------
 316 acres east of the railroad will  be mined  from year 7  through  year
 12, and again in year 23.

 Reclamation will be completed in  year 20  in Section  33 when  a sand/clay
 mix area is reclaimed; in year 26, when a  land-and-lakes  area in  Section
 36 is reclaimed; and in years 28  and 29,  when  the southern  portions  of
 the ISA are reclaimed.  The Troublesome Creek  watershed on-site will
 total approximately SAO acres upon completion  of  reclamation.

 The impacts downstream of the mining and  reclamation  activities can  be
 effectively controlled since there is no  recognized  stream channel on-
 site.   The wetlands  associated with the watershed  will  be reclaimed  to
 at least the pre-mining acreage.

 2.1.6.5   SHIRTTAIL  BRANCH
 Part  of  the Shirttail  Branch watershed will be occupied by the plant
 site,  the ISA,  and  the sand tailings storage pile, all  in Section 30,
 Range  Ik  East.   Mining will begin in the watershed in  year 8  and
 continue  into  year  15.   The last mining in the watershed will occur  in
 year 27.

 Reclamation in year  II  will return approximately 235 acres of the
 watershed  to service,  and an additional 230 acres will be reclaimed by
 year  15.   Sand tailings and overburden reclamation will be.used to
 reclaim  the 465  acres.   The watershed area reclaimed in years 18 and  19
 will be  sand/clay mix  areas.

The section of the watershed scheduled for mining in year 27 contains
 wetlands and a  stream  channel  which  will  serve as a seed source for
earlier downstream reclamation and a buffer to activities upstream.
When this  area  is mined,  sufficient  time  will  have elapsed to have a
reclaimed  functioning  stream and  wetland  system to provide a seed source
and buffer  area  for  the  associated mining  and  reclamation activities.
                                 2-18

-------
2.1.6.6  BRUSHY CREEK
The Brushy Creek watershed will  first  be  impacted  by mining  activities
in year 9.  The mining in this watershed  is  sequenced so  that  mining
occurs over a 15-year span.  The mining and  reclamation  schedule  is such
that at least 32 percent of  the  watershed  will  be  in service at any one
time.

The mining of the easternmost headwaters  of  Brushy Creek  will  take place
from year 11 through year 18.  During  this time, downstream  impacts to
Brushy Creek will be buffered by the downstream segment  in Section 34.
Reclamation of the sand/clay disposal  areas  planned for  this headwater
region will begin in year 20 and continue  through  year 31.   The  reclama-
tion design includes a complex of  swampland,  marsh, wetlands,  and  upland
mixed forests to be reclaimed as part  of  the  sand/clay system  and  will
comprise the reclaimed watershed for the  eastern portion  of  Brushy
Creek.

The upper headwater area of  Brushy Creek  is  scheduled for mining  in year
18 through year 20.  Approximately 268 acres  of this headwater area will
be reclaimed within two years of the completion of mining activities in
this part of the watershed.  The downstream  portion of Brushy  Creek in
Section 34 is scheduled for mining in  years  23  and 24.  Reclamation of
this stream segment will be complete in years 26 and 27 when sand
tailings fill overburden cap is  used to return  the area  to near  original
contours.

Upon completion of the stream course reclamation  in year  27,  approxi-
mately 67 percent of the mined watershed  will have been  reclaimed.  In
year 34, the total watershed will  be reclaimed  to  a total of 3,636
acres.

2.1.6.7  HORSE CREEK
The main stream of Horse Creek and the adjacent wetlands  are  not
scheduled for mining.  The watershed of Horse Creek on-site  is
scheduled for mining in year 18  and years  20 through 22.   Reclamation
                                   2-19

-------
will  commence  immediately following the completion of mining operations
with  the  majority of the watershed being reclaimed to land-and-lakes.

The reclamation  proposed will  return the watershed to service in a short
period  of time.   The post-reclamation watershed acreage will be 728
acres.

2.1.6.8   LETTIS  CREEK
Mining  will  begin in the Lettis Creek watershed,  which has no distinct
stream  channel on-site,  in  year 12 and continue through year 15.  Mining
will  again occur in  the  watershed when the southern portion of the ISA
is mined  in  years 24 through 26,

All areas except the area under the ISA, which will be land-and-lakes,
will be reclaimed sand/clay mix areas.  The first reclamation will occur
in year 22 and,  by year  29,  the watershed reclamation will be complete.

The watershed acreage  following reclamation will  be almost the same as
the pre-mining acreage.   The reclamation plan will replace wetlands in
the watershed with ones  similar to those existing prior to mining to
minimize  downstream  impacts.

2.1.6.9   SUMMARY
The ratio of disturbed land to  undisturbed and reclaimed land within a
given watershed  is expected  to  be kept at a minimum.   Figures 2.1-6 arid
2.1-7 show the overall impact  for the five largest watersheds and for
the total site.   For the majority of time,  the mining plan and the
reclamation  schedule result in  no more than 50 percent of any one
watershed being  in a disturbed  state.  For the total  site, that
percentage would be  40 percent.

The relatively short-terra disturbances to the watershed acreages on the
Complex II site  are  not  anticipated to' result in  negative downstream
                              2-20'

 impacts.  With  reclamation,  the return of the pre-mining function of r.he
 watershed  is  expected.

 There  are  several  other positive aspects of CF's mining and reclamation
 plan relative to the  watersheds.  First, land clearing ahead of mining
 will be minimized  to  reduce  the potential of the runoff from creating
 water  quality or water  quantity problems downstream.  Second,
 reclamation will incorporate a diversity of land forms in a pattern
 designed to provide wetland  systems  for water quality benefits to runoff
 and stream  flow.   Another positive aspect is the rate of reclamation.
 Although initially large  land areas  will be tied up in sand/clay mix
 areas, reclamation of the site is expected to be complete eight years
 after  the last  mining occurs.

                      2.2 SLURRY MATRIX TRANSPORT
 2.2.1  GENERAL  DESCRIPTION
 CF's current  plans for  transporting  matrix involve the matrix slurry
 transport system,  presently  used at  most existing Florida phosphate
 mines.  Slurry  pumping  is a  proven technology,  extremely flexible,
 relatively inexpensive  compared to other methods, and environmentally
 acceptable.

 In the system illustrated in Figure  2.2-1, matrix placed into the matrix
 well is mixed with water  sprayed under "high pressure."  Approximately
 11,000 gallons/minute of  water is required to break down the clay and
 sand matrix into a slurry which can  then be pumped.  The source of this
 water will be clarified and  recycled water from the water recirculation
ditch which receives  water from the  initial settling area (ISA), pit
dewatering, and area  drainage.  'Approximately 6,000 horsepower pumping
     " •' i
capability is then needed to transfer the matrix solids and transport
water  from the  matrix well to the top of the beneficiation plant,
assuming an average pumping  distance of 10,000 feet.  The density of the
 slurry must also be properly maintained.  Pumping at less than optimum
density.(e.g. , 35  to  40 percent  solids) would not transfer the required
                                   2-23

tonnage, and pumping at excessive density can overload  the  pump  motors
and/or plug the system.  The  turbulent  washing  and  scrubbing  action of
the high pressure water pumps and pipeline  all  contribute to  the
processing sequence which  follows,  for  the  matrix must  be broken apart
and diluted with water to  remove  the waste  clay and  silica  sand.

2.2.2  PIPELINE CROSSING OF WETLANDS
Proper planning has minimized the need  for  numerous  crossings of
wetland areas with pipelines  as mining  proceeds throughout  the tract.
The matrix slurry transport system  presents the potential for pipeline
leaks which could cause increased turbidities  in wetland water course
areas should the matrix slurry escape from  the  containment  line.
However, the possibility of this  occurrence is  minimized by the  use of
preventive maintenance practices  such as pipeline inspection  and
rotation along with the implementation  of certain safeguard systems.
These systems would include double  walled pipes and  a low pressure
shutoff system with cutoff valves installed at  both  sides of  the
pipeline stream crossing to assist  in controlling a  pipeline  leak at
these points.

At the Horse Creek crossing (see  Figure 2.1-4A), the matrix pipeline
will also be underlain by  temporary fill across the  stream  channel  which
will have grassed berras on both edges of  the corridor  to prevent erosion
and turbid runoff into the creek  should a leak  or heavy rains occur.

                         2.3  MATRIX  PROCESSING
2.3.1  PLANT LOCATION
The CF Industries' beneficiation  plant  and  support  facilities will
occupy approximately 60 acres.  This  site (Section  30,  Township 33
South, Range 24 East)  is located  one-half mile  south of the town of
Ft. Green Springs, in Hardee  County,'Florida.   In selecting this
particular location for this  phosphate  berieficiation plant, several
                               2-25

-------
 sites  were investigated with the following objectives carefully
 considered:
     • Minimize disturbing environmentally sensitive areas;
     • Minimize the consumption of energy used in the movement of water
        ore,  and waste products;
     • Minimize the cost of transportation facilities (roads and
        railroad),  and utility construction;
     • Minimize fill and ensure the site is all upland;  and
     • Minimize phosphate reserve loss.

Of  the various  sites considered, Sites 1 and 2 (Figure 2.3-1) were the
most promising  in  meeting most  of the  objectives  mentioned above.

Site 1 (Figure  2.3-2) was finally chosen over Site 2 in that it was
 closer to  the centroid of ore and waste disposal; one mile closer to
 rail and power  facilities; and had favorable topography (Site 2 is
 located in the  drainage basin of Shirttail Branch).

 2.3.2   PLANT DESCRIPTION SUMMARY
CF  proposes  to  use mining and processing procedures  common to the
Florida Phosphate  Industry.  Therefore, Figure 2.3-3,  which depicts the
general layout  of  the plant,  is characteristic of Florida phosphate
beneficiation plants.   The matrix will be slurried and pumped from the
mine to the  beneficiation plant.  There  the matrix will  undergo the
conventional  beneficiation process,  consisting of separating the clays
and fines  from  the pebble-sized product  in the washer and feed
preparation  areas  before  being  transferred  to the flotation plant for
processing  to recover the final phosphate concentrate.

CF's facilities  are  planned  to  have  a  nominal capacity of 2,000,000
short  tons per  year  of  phosphate rock  product.  Wet  phosphate rock will
be stored according  to  product  classification in  a storage area with  a
1,000,000 short  ton  capacity.   Product load-out  facilities and  a rail-
road marshalling yard will be located  nearby.  On-site water  will be
provided by  facilities  located  in the  plant hydraulic  station.

Miscellaneous  operation support facilities, including the office,
laboratory,  and parking area, will be located within the plant site
area.

Electric  power lines (tied into the existing Vandolah-Ft. Green Springs,
Florida Power  Corporation 69 kV transmission lines) will enter the plant
from the  east.  A one-mile long railroad spur, linking the plant with
the  main  line  of Seaboard Coast Line Railroad (SCL), will enter the
plant  from  the east.  Vehicular traffic will use the main entrance road
off  Ft. Green  Springs-Ona Road west of the SCL mainline.  A mine road
will cross  the Ft.  Green Springs-Ona Road between Sections 29 and 30.

In mining year 8 (as currently scheduled),  a second dragline will be
added  and the  beneficiation plant  will be expanded at the proposed plant
location.  This expansion will be  identical in process  to the proposed
plant.  Conventional beneficiation and flotation have the purpose of
separating phosphate rock from the associated diluents (carbonate
minerals, quartz sand,  and a mixture of clay minerals).   Conventional
beneficiation  requires  less energy than other methods and is less likely
to be  a source of air pollutants while still recovering  75 to 85 percent
of the  phosphate.   This  is the only matrix  processing method used in the
Florida phosphate industry today.   Figure 2.3-4  shows the generalized
flow process.

2.3.3  WASHER  SECTION
When the matrix is  received at the washer,  it consists of carbonate
minerals, phosphate  pebble, sand-size  grains of  phosphate,  clay parti-
cles of various  sizes,  and quartz  sand.   The washer process  involves a
number of steps:  separating the  oversized material  from  the  matrix;
disaggregating  the  clays  and  phosphatic  ore; washing and separating the
pebble  from the  undersized material  (waste  clays  and feed);  and separat-
ing  the sand-size material so that it  can be treated by  flotation to
recover the fine  phosphate particles.   A simplified process  flowsheet
for a typical washer  section  is  shown  in Figure  2.3-5.

Matrix  pumped  in  from the mine discharges into the matrix receiving box,
located atop the  washer structure.  This receiving box has nine
hydraulically  operated gates which allow distribution of the matrix to
the  three  trains  of the washer section.

2.3.4   SIZING  SECTION
The  sizing of  coarse intermediate product (IP) begins when the material
is pumped  from the  washer area to the primary cyclone.  The -14 mesh
material produced by the washer is pumped to the primary desliming
cyclones.   These  cyclones remove the bulk of the -150 mesh material
present in the feed stream as an overflow stream, which flows by gravity
to the  settling pond.   The cyclone underflow flows by gravity to the
unsized feed storage bin.  The unsized feed material is then pumped to a
secondary  cyclone for  removal of additional amounts of -150 mesh
material (see  Figure 2.3-6 for a schematic of the sizing section).

From this  point the material reports to a sizing box and on to
subsequent  primary  and secondary screens, if needed.  Further processing
divides  the  material for transport to the intermediate product shift bin
or for  additional subsequent processing in the flotation feed cyclone.

2.3.5   FLOTATION  AREA
Sized feed,  or float feed,  is pumped from the sizing section to the
flotation  plant (Figure 2.3-7).   There the feed is subjected to a
standard Florida  phosphate double flotation process consisting of three
major processing  steps designed  to produce concentrate and sand
tailings:
     •  A rougher  (fatty acid) flotation circuit to achieve high recovery
        of  phosphate,  with bulk rejection of sand tailings;
     •  Collection and  cleaning of initial concentrates prior to cleaner
        flotation; and
                                2-33

      • Cleaner (amine)  flotation  -  a  second  stage  of  flotation to
        further concentrate  the  product.

 The flotation area is divided into  two  identical,  independent  sections
 called trains, each of which is composed  of  a  bank of float  feed
 cyclones, rougher flotation machines, acid scrubbers,  acid wash boxes,
 and cleaner flotation machines.   A  common final  concentrate  pump  and  a
 common sand tailings pump are set on-grade for disposition of  each
 material.

 The final concentrate pump delivers the final  concentrate to a pair of
 cyclones  over  one of three concentrate dewatering  shift bins and  then  to
 the wet  rock storage pile.  The GMT pump  and a booster pump  deliver the
 rougher  and cleaner  tailings to the disposal area  or  to the  sand/clay
 mix area.

 2.3.6  WET  ROCK STORAGE
 After  beneficiation,  Che wet rock pebble,  IP, and  concentrate  are loaded
 from the  shift bins  via  conveyor to the storage pile.  The product is
 dumped, by  means  of  a conveyor,  into piles according  to size,  BPL (bone
 phosphate lime) grade, Fe, Al  and  MgO (iron,  aluminum and magnesium
 oxide) content, and  other factors.  This short-terra storage area (Figure
 2.3-8) will  contain  rock with  a  moisture content between 12 and
 16  percent.  Drainage  from the  area will be collected and returned to
 the beneficiation plant  circuit.   Since these products are sorted,
 conveyed  and shipped wet,  they  should pose no particulate air  pollution
 problems.

The wet rock is then  transferred by conveyor  belts to the rail  car
 loading facility.  Wet rock  is  loaded  into rail cars for  shipment  to the
CF chemical  plants located  in  Bartow or Plant City.

-------
 2.3.7   PHOSPHATE PRODUCT DISPOSITION
 The phosphate rock resulting from this expansion will be utilized by
 CF's Plant  City and Bartow phosphate complexes to replace an existing
 rock supply contract.  The phosphate rock resulting from the second
 expansion would also be utilized by CF's two phosphate complexes to
 replace rock from contracts with other raining companies and rock supply
 provided by Hardee Complex I.

 2.3.8   PLANT CONSTRUCTION
 CF  anticipates  construction for their proposed mining and beneficiation
 plant  to be  completed within 19 months,  allowing 2 months for land
 clearing, 3  months for grading and excavation, and 14 months for plant
 construction.   CF  plans to employ approximately 200 workers for this
 construction, drawing on the local labor pool to the greatest extent
 possible.  During  peak periods, the number of workers  may increase to
 400.

 A projected  750 to 1,000 KVA will be required during the construction
 period  to meet  all  electrical  power needs for lighting,  pumps,  welding,
 etc.  These  needs  will be met  by 1,000 KVA service at  the mine  site.  In
 addition, 150 gal/day gasoline  and 250 gal/day diesel  oil will  be
 consumed by  heavy  equipment and will be  provided by the responsible
 construction contractor.   Energy demand  can be expected  to  fluctuate
 greatly during  the construction period.

Lubricants and  fuels  to service vehicles  will be stored  in  small,
 stationary  or portable containers above  ground and in  a location in
keeping with vehicle  fuel  and  lubricant  requirements.   These containers
will be maintained  by the vehicle owners.

During  the construction phase,  perimeter  ditches  will  be installed to
collect runoff  from the plant  site area.   Dam construction  areas will
also be enclosed by perimeter ditches  to  intercept  runoff.   In  the  plant
site area, all  areas  not  permanently surfaced will be  landscaped and
revegetated.  Access  road  shoulders,  powerline right-of-ways, and
pipeline corridors  will be graded and  revegetated.
                                     2-38

-------
During  the construction,  compliance  with Article IV—Mining Ordinance,
Hardee  County Land  Development  Code  will minimize adverse impacts to air
quality.  Dust  or smoke  emissions  from heavy machinery, vehicular
travel,  and open burning  will  be  effectively controlled.   Roads within
the plant area  will  be  paved  to minimize particulate pollution.

The capital cost for the  CF mine  and beneficiation plant  is estimated at
$129,000,000 (1981  dollars).

2.3.9   ENERGY REQUIREMENTS AND OPERATING PERSONNEL
The beneficiation plant's electrical energy needs are projected to be
18MW.   The mine and  slurry  transport system will require  approximately
13MW.   The highest  anticipated  requirements are  predicted at 38MW.  CF
is served by FPC on  Rate  Schedule  1ST 1-Interruptable General Service,
Time of Use.  This  schedule provides that FPC may elect to curtail power
service to CF's operation during  critical load periods.

CF has  continued to  investigate and  implement energy conservation
concepts and through the  engineering phase of the plant design will
continue this practice.  Metering  devices will be installed to
continually monitor  individual  load  centers in order to evaluate energy
demand  to accomplish effective conservation practices.  Power factor
control will be implemented as  required in order to maintain a desirable
power factor.

It is estimated that 400 gal/day  of  gasoline and 100 gal/day of diesel
fuel will also be employed during  plant operation.

Operating personnel  required  for  the mine and beneficiation plant at
startup will be 139.  That total will  increase to 301 with the proposed
expansion in mine year 8, which happens to coincide with  the depletion
of Complex I reserves.  This  increase  will be largely filled by
personnel from  the Complex 1 mine.

2.3.10   REAGENT.  FUEL.  AND LUBRICANT STORAGE
The  reagent  area  of the beneficiation plant is diagrammed  in
Figure  2.3-9.   As shown,  the area contains bulk reagent storage tanks,
mix/use storage tanks  in which the concentrated reagents are mixed with
other reagents  or diluted to useable concentrations, reagent truck
unloading  pumps,  reagent  transfer pumps which move reagents from  the
bulk storage  tanks to  the mix/use tanks, reagent feed pumps which pump
the  reagents  into the  point of use in the flotation processes, the
instrument air  compressor/dryer package, and an oil separator/skimmer
package.

CF's above-ground reagent and underground fuel tankage requirements are
specified  in Table 2.3.10-1.  All reagents are delivered by tank  trucks.
The  reagents, with the  exception of ammonia, are stored in vertical,
cylindrical, closed top,  carbon steel tanks.  These tanks are vented to
the  atmosphere; the No.  5 fuel oil and the kerosene tank vents are
equipped with flame arrestors to preclude open flame or electric  arcs
from igniting the fumes  in the vapor spaces of these tanks.

Ammonia is stored in a  horizontal, cyclindrical, carbon steel pressure
vessel,  designed  for a  working pressure of 250 psig, and having appro-
priate  pressure relief  valving.

The No.  5  fuel  oil tank and the kerosene tanks are set within indivi-
dual, concrete-walled areas for fire protection purposes and for
emergency  spill containment.  These two areas have valved sumps for
manual,  controlled release of water accumulation to the reagent area
drainage system.

The bulk reagent  tanks  are fitted with level gages visible from the
truck unloading pumps,  while the mix/use tanks are fitted with high
level switches  that shut  off pumps or valves supplying reagent to their
respective tanks.

The  reagent  tanks,  other than the ammonia storage bullet,  are  fitted
with vent, overflow,  and drain connectors, all directed  to  the  reagent
area drainage  system.   In addition, all pump leakage is  directed  to this
same drainage  system.

The  reagent  area drainage system consists of an area concrete  slab  and
trenches  which direct  all runoff or spillage through an  oil  separator.
This separator removes the water insoluble oil phase from  the  area
drainage.  This material can then be reclaimed to a fatty  acid/fuel oil
mix  use  tank.   The  water phase drains, via open swales,  to  the
beneficiation  plant water recirculation system.

The  reagent  area is lighted to appropriate industrial standards to  allow
for  mixing of  reagents at night and to allow for the monitoring of  the
area for  spillage.

Gasoline  and diesel fuel are stored in underground tanks and vented to
the  atmosphere according to standard API practice.

Lubricant oil  is stored in drums in a building near the maintenance
building.  A Spill  Prevention Control and Countermeasure (SPCC) Plan
will  be prepared for  the reagent fuel and lubricant storage  area  to
conform with regulations specified  in 40 CFR 112.

                  2.4   WASTE SAND AND CLAY DISPOSAL PLAN
2.4.1  INTRODUCTION
The CF ore body is  composed of-a mixture" of; non-uniform ,ssize phosphate
pellets, disbursed  in  a matrix of silts, clays, and coarser grained, sand
particles.  Since sand and clay have no economic importance  to the
operator, the  only  resource for which the proposed  mine and benefici-
ation facility is being planned to  recpveSr,;is the phosphate value
occurring jin the -3/4  inch to +150  meshes izeirrange.  Consequently,
                               2-43

-------
all  sand  and  clay removed from the processed ore will be disposed of as
waste  materials throughout the life of the proposed Complex II project.
CF estimates  that raining and processing ore from the Complex II site
will continue for at least 27 years before the existing phosphate
resource  becomes exhausted.   During this time, approximately 97 million
short  cons  (s.t.) of clay and 305 million s.c. of sand tailings (CF
Industries, 1983) will  be generated and disposed of at various locations
prepared  to receive the materials within the Complex II boundaries.
Disposing of  sand and clay wastes for  use as backfill and reclamation
materials for mined and disturbed lands Is one of the primary objectives
of the CF waste disposal plan*

The  waste disposal method selected by  CF is sand/clay mixing.  Several
factors were  considered In reaching a  decision on the method of waste
disposal  to be employed at the Complex II mine.  From a materials
handling  perspective, the mix reduces  the equipment,  energy, and
manpower  requirements when compared with traditional  practices of
handling  sand  and clay  separately*   Also,  higher total percent solids
and  increased  consolidation rates have been observed  from tests using
the  sand/clay  mix technique  (Ardaman & Associates,  1982).   Both features
offer positive incentives to the  operator to pursue sand/clay mixing as
the  primary .waste disposal method.   Sand/clay mix also offers enhanced
potential for  reclamation over  conventional clay settling areas.  The
increased dewataring  potential  of the  sand/clay mix also allows for
lower dams than typically constructed  in conventional disposal systems.

Accumulation of  information  on  the  operational aspects of  the sand/clay
mix  technique  started In 1980 when CF  began a production scale test with
sand/clay mix  as  the waste disposal  technique.   CF  initiated the program
to honor  its commitment to the  Hardee  County Board  of County
Commissioners  to  investigate  new  technology that might eliminate long-
term conventional  clay  settling systems.   Encouraging test  results  from
work completed at  the Complex I sand/clay  mix site  and the  favorable
sand to clay ratio  of the  Complex II ore  have directed CF  to commit to
                              2-44

-------
this method as the primary waste  disposal  technique  for  subsequent
reclamation at the Complex II mine  site.   The details of the waste
disposal plan are discussed  in  the  following  section.

2.4.2  SAND/CLAY MIX PROCESS
Sand-clay mix refers to  a process in which sand  and  clay components,
separated during mining  and beneficiation,  are recombined into  a suit-
able mix for disposal  in a mined  area.   In the CF mix process,  the waste
clay generated from the  beneficiation processes  is routed to a
containment area for storage and  subsequent consolidation to higher
percent solids.  When  clay consolidation  reaches  the 12  to 18 percent
range, it is removed by  dredge  and  pumped  to  a mix  tank  where mixing
with dewatered sand tailings from the beneficiation  plant takes place
(Ardaman & Associates, 1982).   The  sand/clay  mixture is  then pumped from
the mix tank to a designated disposal site.   Disposal areas  are designed
to receive sand-clay mix over mined  lands  to  final  fill  elevations that
consolidate to within  approximately  2-3  feet  above the original average
pre-raining elevation by  the  end of  the reclamation period.

2.4.3  INITIAL SETTLING  AREAS (ISA)
An above-ground settling area is  necessary to receive diluted clay
slurries for storage and consolidation to  use in  sand-clay mixing. To
satisfy this requirement, CF plans  only  one above-ground settling area
to be subdivided into  three compartments.   Designated as the Initial
Settling Area, or ISA, the structure is  necessary for the successful
execution of the sand/clay process.   The  ISA  receives low-percent (i.e.,
2 to 5 percent) solids clay  slurries originating  at  the  beneficiation
plant and contains them  until the; desired  12  to.18 percent  solids are
reached for sand/clay mixing.   The design  of  the  ISA., in available
storage volume*(acre-feet), must  be  commensurate  with the peak  demands
of the total system.   In other  words/ storage capacity must  equal- clay
production- and consolidation requirements  as  they; develop to the maximum
operating demands of the project.  On this  basis, the ISA has been
designed to ultimately provide  20,000 acre-feet  of storage volume. This
requires ISA dam walls to be constructed 40 feet  above the average(
                              2-45

-------
 existing grade and encompass 760 surface acres (580 acres storage;  180
 acres dam construction) at its maximum size.

 During the last three mining years, 563 acres of the  ISA will be mined
 and  reclaimed.  At the conclusion of all mining activities,  the mix
 technique will be used to remove the clays in the remaining  section by
 mixing with stored sand tailings, and the dam walls contoured to near
 natural  grade.

 2.4.4.  SAND/CLAY MIX AND DISPOSAL AREAS
 The  design and construction of dams required for the  impoundment of clay
 and  sand/clay wastes  will comply with all provisions  of Chapter 17-9 of
 the  Florida Administrative Code.   A professional engineer, registered in
 Florida  and experienced in earthen dam design, will be responsible  for
 the  design of all  retention dams  built on the property.

 When construction  is  complete,  the dam faces will be  planted in grasses
 to inhibit  wind  and water  erosion.   The  vegetative cover will be mowed
 as necessary  to  allow visual  inspection  of the dam surface at all
 t imes.

 An inspection plan for all dams will adhere strictly  to the provisions
 of Article IV Hardee  County Mining Regulations of the Hardee County Land
 Development Code,  and Chapter 17-9  of the Florida Administrative Code.

 All  dams  will  be  inspected daily  by  a CF  employee who  has  been
 instructed  by the  design  engineer.   A monthly report,  including  a copy
 of the daily  inspections,  will  be  submitted  to Hardee  County.  The
 design engineer  or another comparably qualified engineer will make
 annual inspections of  all  the retention dams  on the  property. The
engineer  will  submit  his  findings  in writing  to the  Florida Department
of Environmental Regulation.  A copy of  this  report  and any corrective
action required will  be forwarded  to Hardee County.
                           2-46

-------
Sand/clay mix disposal areas must  first be constructed  over mined  lands
before filling can proceed.  The disposal  sites  are  constructed  using
available overburden for earthen dams.  Dams  are  engineered  for  safety
and utility  in the same manner  as  conventional  settling areas.   The
design heights above pre-mining grades are a  function of  the  ultimate
thickness of  the sand/clay mix  required to consolidate  to the desired
final elevations for reclamation.  This is accomplished with  sand/clay
mixes stored  behind dams that average  14.7 feet  above pre-mining average
grades for the Complex II area.  Each mix area has been planned  to reach
the desired  final topography  for reclamation  by  storing only  those
quantities of sand/clay mix required to achieve  this objective.

Table 2.4.4-1 shows average dam heights above grade  and final grades of
the reclaimed areas after capping  the  sand/clay  mix  with materials from
the surrounding dams.

Figures 2.4-1A and 2.4-1B present  a  plan view of all areas required to
contain the  sand/clay mix and overburden/tailings for the east  and west
sectors of Complex II.

2.4.5  SAND/CLAY WASTE DISPOSAL PLANNING
Many basic assumptions supporting  the  CF sand/clay waste disposal plan
were developed from actual  field tests conducted by  CF  at its Complex I
mine site.   The progress of  the CF sand/clay  technique  has been
monitored by Ardaman & Associates, Inc. under a  grant  from FIPR (Ardaman
& Associates, Inc., 1982).  A recent grant has been  awarded to Ardaman &
Associates,  Inc. by FIPR to continue monitoring  the  CF  sand/clay mix
technique.   Some of  the major conclusions  resulting  from that sampling
and monitoring program are:
     • Consolidation of  the  sand/clay  mix  during the filling and  resting
       periods within the 2-year study resulted  in an  average percent
       clay  solids of 34 percent at  the  end  of the study period.
     • Computer simulations of  the filling  sequence  for the west
       compartment of  the  reclamation  area using laboratory
                                2-47

        consolidation properties  show reasonable agreement between
        calculated  and observed values.

Land use  planning  for sand/clay  disposal areas was the subject of a
paper  prepared  by  CF for  presentation at a FIPR symposium on
"Reclamation  and the Phosphate Industry" (Florida Institute of Phosphate
Research,  1983).   In addition to the physical properties of sand/clay
mix consolidation  and waste  disposal advantages inherent with the
method, the paper  also evaluated the vegetative support and water
retention  qualities  of sand/clay as  applied to land reclamation.  In
essence,  nutrient  analysis  of the sand/clay and overburden soils show
higher  nutrient content  in  the sand/clay soil than in the overburden.
The combination of the sand/clay mix and the overburden soils used for
capping should  provide a  desirable growing medium for a variety of
vegetation.   Soil  permeability is lower in sand/clay than typical over-
burden  soils  which would  be  an advantage in wetland restoration.  The
sand/clay  mix soils  may be  enhanced  for other types of vegetation by
increasing sand to clay ratios and/or overburden caps placed over the
sand/clay  mix areas.

2.4.6  TAILINGS
Some rained areas will be  backfilled  with sand tailings that are not used
in the  sand/clay mix  program.  These areas are shown on Figures 2.4-1A
and 2.4-1B.   The tailings may be pumped directly from the beneficiation
plant  to  the  reclamation  site  or temporarily stored at a stockpile area
for later  use.

Tailings  provide an  excellent  material  for backfilling.  Therefore, sand
tailings  and  overburden will  be  used to construct a permanent right-of-
way to  relocate the  existing  FPC 230KV  transmission line which passes
through the east sector of Complex II.   Other tailings and overburden
quantities are designated for  restoring certain stream channels and
other mined out areas of  the  property.
                               2-51

-------
 Revegetation over tailings usually  requires  a 6-inch  to  12-inch  over-
 burden cap to retain moisture and provide  some  nutrients  for  plant
 growth.  CF plans to cap the tailings acres  with overburden to establish
 a suitable base for subsequent  revegetation  and  to  reduce  the  effects  of
 wind erosion.

 2.4.7  SUMMARY
 In total, over 60 percent of Complex II will be composed of sand/clay
 mix areas at  the conclusion of mining.  Assumptions used in sand/clay
 disposal planning were primarily the results of actual field  tests
 conducted by  CF at its Complex I mine site.  An important consideration
 for the plan  was predicting consolidation  rates for reclamation.
 Consolidation  rates  for 2:1 sand/clay mix  ratios, stacked 40 feet, will
 attain 40.9 percent  clay solids 5 years after filling (Ardaman &
 Associates, Inc.,  1983).   Each CF sand/clay area has been designed to
 consolidate 2  to 3 feet above the pre-raining average grade approximately
 5  years  after  filling.

 Other waste disposal  consists of tailings  and overburden at selected
 sites over  the  property,  graded  to  approximate  pre-raining contours.

 One  above-ground settling area will  be required  to contain diluted clay
 slurries  until  percent  solids reach  the 12 to 18 percent  range.  Clays
 will  be  removed  from  this structure, and its dams will be reduced to
 meet  abandonment and  reclamation requirements at the conclusion of
 mining.

                         2.5   MINE WATER USE PLAN
 2.5.1  PROCESS WATER  REQUIREMENTS
Water is  an essential  ingredient  in  many of CF  Industries'  phosphate
mining operations.  Figure  2.5-1  presents  the key  water uses  for  the
mine  as planned  by CF,  including  the respective  sources  and final

disposition  of the water.  Recycled water is used extensively as a
medium in many processes to reduce the overall consumptive use of water.
Matrix transport  and  process water is used as follows:
      • Ore Transportation - Recycled water is required to slurry the
        matrix  as  a medium for transporting the matrix to the
        beneficiation  plant.
      •  Washer  and Sizing Sections - Recycled water is used in the
        washing  process  to separate pebble, sand,  and clay size
        fract ions.
      •  Rougher  Flotation -  Recycled water is used in the rougher
        flotation  circuit  to dilute the float  feed in the rougher
        flotation  machines.
     •  Amine Flotation  -  Deepwell water is used in the araine flotation
        circuit  for  feed  dilution.  Recycled  water may be used as an
        alternative  based  upon water quality  and flotation
        cons iderat ions.
     •  Waste Disposal - Recycled  water and water  from the flotation
        circuits is  used  as  a medium for transporting  waste clays and
        sand  tailing from  the  beneficiation plant  to disposal area.

2.5.2   BENEFICIATION PROCESS  REAGENT  REQUIREMENTS
Several reagents  are utilized  during  the  feed preparation and flotation
processes of the beneficiation plant.   These  reagents include ammonia
(caustic may be considered  as  a substitute to using ammonia as a
neutralizing reagent),  fatty acid,  fuel oil,  amines,  kerosene,  and
sulfuric acid.  The reagents  are  used  in  dilute quantities to separate
phosphate rock  from sand  particles  in  the  flotation circuits, thus
achieving the desired level of phosphate  rock recovery.
                               2-54

-------
The reagents  used  and  their  expected dilution ratio in the flotation
discharge water, assuming  the  reagents pass through the flotation
circuit without chemically  reacting,  follow:

                          AVERAGE  USAGE

       Sulfuric Acid           2,306                   13,096:1

Flotation discharge waters  then  mix  with  other discharge streams from
the beneficiation  process where  the  majority  of these reagents  react
forming chemically insoluble complexes and precipitates.  In addition, .
most reagents have an  affinity for clay particles.   Consequently, as the
float circuit discharge waters mix with water containing clay,  the
opportunity for further reaction takes place.   As  a result of  these
chemical reactions and the  subsequent settling out  of clay particles in
the disposal  areas, only trace concentrations  of the reagents  are
expected to end up in  the plant  process recycle water.

2.5.3  WATER RECIRCULATION SYSTEM
CF plans to recycle water to the greatest extent possible for  use in
plant operations.  The mine  water  recirculation system proposed
(Figure 2.5-2) will recycle  93.5 mgd, which is projected to be adequate
for the required uses.  Since  mining and  beneficiation processes operate
with a fixed water usage to  production rate ratio,  demand is fairly

constant.  Therefore,  no  significant  fluctuations in water usage are
expected.

Seasonal variation  in  rainfall  and evaporation rates can affect the
recirculation  system's  water  supply;  however,  annual rainfall within the
region  is 55  inches  as  opposed  to the annual  evaporation rate of
48 inches.  This difference of  7  inches is  considered as a make-up water
supply  source  when  it  can be  collected.  Chapter 17-9 of the Florida
Administrative Code  limits  the  rate  at  which  the water level in any
active  settling  area can  be raised or lowered.  This limits the variable
holding capacity of  any pond,  thus making it  impossible to recover all
the net rainfall available  during wet periods.  Close control and
management of  the pond  system can provide for  rainfall recovery of
approximately  70 percent.

This excess can  be used during  the pre-filling of the ISA in the initial
year of mining to provide a surplus  to  the  system and help offset system
losses.  A seasonal  deficit can result  if the  reservoir's capacity is
insufficient  to  collect enough  rainfall during the wet season to
counter-balance  shortages  during  the  dry season; or if the catchment
area is insufficient to offset  the loss between rainfall and evaporation
rates.  During the dry  season,  this  deficit due to evaporation can
increase system  losses.   As planned,  the system's surge capacity should
aid in  eliminating these  seasonal changes.  If necessary, well water can
be drawn as make-up  during  the  dry season.  Conversely, during the rainy
season, if the accumulation of  rainfall and runoff in the system exceed
the storage capacity, discharges  may  be necessary.

The major water  loss from  the recirculation system is entrainment in the
waste clays.  CF's use  of sand/clay mix for waste disposal has the
advantage of more rapid dewatering resulting  in increased water
recycling and a  lower rate of water  loss due  to entrainment.  The
process, however, has not been  thoroughly tested for all types of clay.
Consequently, the degree  of success  for water  recovery is not known.
                               2-57

-------
 Minor losses from the water recirculat ion system are identified in CF's
 mine water balance (Figure 2.5-1).

 2. 5. A  CONSUMPTIVE USE - GROUND WATER WITHDRAWALS
 On  April 7,  1976, CF Mining Corporation was issued a Consumptive Use
 Permit (CUP) from the Southwest Florida Water Management District
 (SWFWMD) for its Hardee Phosphate Mining Complex.  This permit was
 originally based on  a three phase development plan - two mining
 operations (Hardee Complex I and Hardee Complex II) and a proposed
 phosphate  chemical processing  plant.   Expiring in late 1981,  this permit
 authorized an  average water withdrawal of 15.74 million gallons per day
 and a maximum  withdrawal of 20.2 million gallons per day.

 CF  applied for and received renewal CUP No.  203669 from SWFWMD on
 January  6, 1982.   Water use projections for  this permit were  based on
 efficient  water use  at Hardee  Complex I and  the implementation of the
 plan to  construct  a  benef iciation plant at Complex II.   Consequently,  CF
 proposed decreased average and maximum withdrawal rates from  the
 original CUP.   A comparison between the original and the renewal
 consumptive  water use permits  is shown below:

                                 Original CUP          Renewal CUP
                             MGD/Max.   MGD/Avg.   MGD/Max.
     Authorized Water          20.20      15.74       10.57        7.85
       Consumption

This comparison shows  a  reduction  of  almost  50 percent  in overall  water
consumption from the original  permit.   The renewal  CUP  permit,  under
which CF currently operates,  has an expiration date of  January  5,  1988.

The permitted wells designated  for Hardee Complex II will  be  located  in
the vicinity of the benef iciation  plant  site (Figure 2.3-2).  These
wells collectively should yield approximately  5.0 million  gallons  per
day for total plant operations.
                               2-58

-------
Current plans  indicate a  need  for  ground water withdrawal to provide a
primary source of clean water  for  the amine flotation circuit and to
offset water losses  from  the  recirculation system.

The projected material balance and ground water withdrawals were
developed using 86 percent  solids  in the shipped phosphate rock, 80
percent solids in the sand  tailings and 18 percent  solids in the waste
clays.  Colloidal entrainment  was  calculated considering a deduction for
the water that is in the  matrix when it is moved and ends up in the
waste clay.

Water will be required before  the  actual initiation of mining for use as
potable construction water  and for pre-fill ing the  ISA.   The tendency of
the clays to gradually release water necessitates pre-filling at the
outset of operations, although this water will eventually be recovered
from  the clays over  time.   The water level in the ISA will be maintained
at an elevation sufficient  to  provide rapid flow return to the plant
water pool for plant start-up.

CF proposes to drill two  24-inch production wells (designated Well No. D
and E) to a depth of approximately 1,200 feet into  the Avon Park
Limestone (Figure 2.5-3).   In  addition, two smaller wells (designated
Well No. F and G) will be developed to supply the operation's domestic
and potable water needs.

Wells permitted for  Hardee  Complex II are described below:
     Well No. D:  24-inch diameter, 1,200 foot depth—to be used as the
                  main production  well for ground water supply to the
                  flotation plant.
     Well No. E:  24-inch diameter, 1,200 foot depth—to be used for
                  fresh water  dilution in mixing reagents.  Casing sized
                  to accommodate production well pump in the event of a
                  production  well  failure.

                  domestic water well.
     Well No. G:  4-inch diameter,  500  foot depth—proposed  to be  used
                  as a potable water  supply during construction.

CF has accepted and agreed to comply  with  the renewal CUP's  operational
conditions.  To maintain compliance with  the permit, CF  will minimize
drawdown impacts to the Floridan and  water-table aquifers,  perform the
required ground water level and water quality monitoring,  and prepare
the necessary monthly pumpage reports.

2.5.5  OTHER WELLS
A total of 25 monitor wells are located at  the  CF's Hardee  Phosphate
Complex II.  These include:  a deep well  with a depth of 1,702 feet;
6 lower Floridan wells with depths  ranging  from 950 to 1,200 feet;
4 upper Floridan wells to depths of between 375 and 433  feet below
ground surface; and 14 shallow aquifer  wells ranging in  depth from 35  to
66 feet below ground surface.  The  wells  were installed  as  part  of the
study 'for the consumptive-use application required by SWFWMD and  to meet
the ground water monitoring regulations established by Hardee County.

As mining progresses, 9 of the 25 wells will be eliminated.   These
include 4 lower Floridan wells, 2 uppper  Floridan wells,  and 3 wells
from the shallow aquifer.

State regulations require that appropriate  well abandonment  procedures
must be followed.  These procedures have  been established  to prevent
drainage of upper aquifer waters to lower aquifers through poor  well
abandonment techniques.  Floridan Aquifer  wells will be  abandoned  in
accordance with the rules of  the Department of  Environmental Regulation,
Chapter 17-21, "Rules and Regulations Governing Water Wells  in Florida."
The abandonment procedure would involve sealing the well from the  bottom
to the top with neat cement grout.  Shallow aquifer wells  would  be
                               2-61

-------
 physically removed  as  the  sand  is  stripped  and  phosphate  matrix is
 removed.

 2.5.6  MAXIMUM WELL PUMPAGE
 Maximum well pumpage is expected to  occur during  the  pre-filling of the
 settling pond (ISA).  Estimates call  for well water  to  be  pumped at the
 maximum capacity of 4,400 gpm for 90  days,  the  time  required  to fill  the
 ISA.   However,  due to a possible need  to curtail  withdrawal during the
 dry season (to  comply with SWFWMD regulations), the  actual  pumping time
 may vary.

 2.5.7   MINE  PIT  DRAINAGE
 The dragline  method for mining requires a relatively  dry  pit,
 consequently  mine  pit dewatering is necessary to  effectively  recover  the
 maximum quality  and quantity of phosphate matrix.  CF plans to  pump at  a
 rate of approximately 2,000 gpm to maintain the desired pit water  level
 elevation.  Should this pumping rate  fail to lower the water  level  to
 acceptable limits,  the  use  of additional dewatering pumps,  the  placement
 of  cast  spoil against  the  sidewall, the use of well points  for  ground-
 water withdrawal,  or  other  methods  may be used to reduce seepage through
 the pit  wall.

 Since the matrix underlies  the surficial sands containing the surficial
 aquifer, maintaining  the desired water level in the pit results  in  the
 temporary and localized lowering of the water table in the vicinity of
 the mine cut.

 The degree to which  this  lowering  of the water table or drawdown may
 cause undesirable  effects  is  a function of  aquifer hydraulic properties,
 the geometry  of  the  mine cut,  and  the length of time dewatering
continues at  each  location.   Water  table drawdown  impacts  are  site-
 specific, short-term,  and  should result in  no permanent water  table
changes.
                             2-62

-------
 If drawdown  impacts do  become  excessive at the property boundaries, CF
 will  draw  upon  the  latest  mining and engineering techniques in minimiz-
 ing or eliminating  the  problem.   These techniques include back filling
 mine  cuts  along property  boundaries and, when necessary, digging rim
 ditches between the open mine  pits  and property boundaries.  Through the
 maintenance  of  the  water  level in these ditches, a recharge area would
 be created preventing the  current water table elevation from declining
 beyond the boundary of  the ditch.

 2.5.8  SURFACE  WATER RUNOFF
 At present,  surface water  runoff at the proposed site is distributed to
 on-site streams  and can primarily be attributed to rainfall occurrences.
 Factors which influence the water discharge to each stream are soil
 permeability, vegetative cover,  land gradient, and drainage area.   CF's
 planned water recirculation system (including the active waste disposal
 areas, the clear water  pond, and the recirculation ditches) will reduce
 this  runoff  by  retaining a portion  of the rainfall for use in the
 recirculation system.

 Planned post-mining reclamation  activities within portions of each
 watershed are expected  to  return the flow characteristics of most  down-
 stream drainage systems back to  approximate pre-mining streamflow
 conditions.  Balancing  pre- and  post-mining watershed conditions will be
 accomplished by plans which include the creation of lakes and wetlands,
 and increasing  the surface  storage  capacity at the site.  In addition,
 the drainage basin of each  stream on the mining tract will be restored
 to approximately its pre-mining  size.   Some of the major components of
Hardee Complex  II* s drainage system during the operating and
post-operating  phases are  illustrated  in Figures 2.6-6,  2.6-7, 2.6-8,
 and 2.6-9.

During periods  of excessive rainfall,  expected during June, July,
August, and September,  water which  exceeds the system's  water handling
design capacity will be discharged  via CF's NPDES permitted outfalls.
                                     2-63

-------
 The water balance planned for the CF project  uses  retention  capacity  and
 recirculation efficiency to determine  the make-up  water  needs  of  the
 development.   The design of the recirculating water  system (Figure
 2.5-2)  allows for the segregation of process  recirculation water  within
 the system from the overload flow outside of  the system.  The  ISA will
 be  designed to contain a 25-year storm rainfall event  (defined  as having
 9.63  inches of rainfall  in a 24-hour period)  and release  12  inches  of
 water  in  a 24-hour period.  The size of each  area  predicates a minimum
 number  and size of release structures.  The preliminary  locations of
 these  spillways are shown in Figure 2.5-2.

 The northern  section of the ISA will have two discharge  structures
 located in the south end and discharging into the  second  section.   There
 will  also be  a spillway in the southeast corner of the northern section
 which will discharge into the circulation ditch.  Water  which  is  given
 up  by  the waste clay will decant further in the second section  and  will
 be  discharged into the extension of the water circulation ditch through
 two discharge structures.  The water circulation ditch west  of  the  SCL
 railroad  will be connected to the east-west ditch east of the  railroad
 through a controlled discharge structure.  This will provide for  the
 necessary make-up water  to the mine for matrix pumping.

 Recirculated  water will  pass through the ISA into the recirculation
 ditch  along the southern and eastern boundaries of the ISA,  and report
 to  the  mine- (as  required)  and  the  plant through the northern ditch  to
 the hydraulic  station.

2.5.9  WATER DISCHARGE
CF's objective  to  achieve  a  balanced wastewater disposal program  can be
realized by minimizing the  frequency and  volume of wastewater discharged
while maintaining  its  quality  and  the water quality of the receiving
waters.

To minimize the  frequency  and  volume of discharge,  CF' plans  to recycle/
recirculata as much  water  stored  in the interconnecting ditches and
                             2-64

-------
ponds as possible.  As a result of  these  efforts,  discharges  of treated
process vastewater  should  typically occur during the  rainy season at
times when accumulated rainfall and runoff exceed  the storage capacity
of the settling  ponds and  recirculating water  system.  This should  occur
primarily during the months of June,  July,  August,  and  September.

Major inputs to  the recirculating water system will include clarified
water from the settling areas, mine-cut dewatering water,  and  stormwater
from in and around  the plant  complex.  As water  inputs  to  the  recir-
culating water system exceed  that amount  required  for matrix  pumping and
plant operations, occasional  intermittent discharges  will  result.

To maximize reuse of water and minimize both ground water  withdrawal and
discharge of process waters,  CF may incorporate  other water conservation
practices into its operation  if proven successful  through  site-specific
experimentation.  One such practice that  CF may  experiment with  is  the
use of recirculating water in lieu  of freshwater  in the  flotation
circuit of the beneficiation  plant.  If successful, freshwater will be
reduced, decreasing this input to the overall  plant water  balance.

The proposed water balance (Figure  2.5-1) specifies that an average of
2.48 mgd is expected to be discharged on  a  daily basis.  Reduction of
this rate depends on how successful or unsuccessful CF  is  in  the
utilization of other water conservation efforts.   Success  with any
experimental water use practice is  highly dependent on  site-specific
conditions including matrix composition,  clay  settling,  plant  design,
and material utilization.

2.5.9.1  CF INDUSTRIES' PROPOSED WATER DISCHARGE  PLAN
Each water management alternative evaluated provides  its own  positive
and negative impacts.  CF proposes  to discharge  to  surface waters either
directly or via wetlands.  CF's primary discharge  of  clarified water is
expected from the recirculation system into Shirttail Branch  and/or Doe
                                     2-65

-------
 Branch.   An  alternative  surface  water  discharge  point  is  also proposed
 into Payne Creek.   Discharge  to  Payne  Creek is expected to be via pipe
 and open ditch into wetlands  by  sheetflow.   The  surface water discharge
 outfall locations selected  for utilization  are illustrated in
 Figure 2-5.2.  Payne Creek wetlands discharge outfall  will be an
 alternative discharge location and will be  used  as the operation
 requires and as permitted by  receiving water characteristics.

 Discharge of clarified treated process water to  receiving waters will be
 required during or after the rainy season when accumulated rainfall and
 runoff exceed the storage capacity of the water  recirculation management
 system.

 Discharge  outfall  locations at Shirttail Branch  and Doe Branch were
 selected primarily due  to their proximity to the plant site and because
 direct discharge  to  other surface waters offered no particular
 environmental advantage.   With the exception of  Horse Creek,  all other
 water receiving systems  are similar,  characterized as having  headwater
 systems with  large wetland  .-omplexes,  relatively flat elevations, low
 stream gradients and mild stream  velocities.  These systems flow
 primarily  for short  periods  of time following the occurrence  of
 rainfall.  No individual  system appears to demonstrate an  advantage over
 any other  from either a  functional, operational,  or environmental
 standpoint.   Horse Creek  was not  considered  for discharge  since  its
 location is approximately 5 miles  from  the  proposed plant  complex.

 To utilize the Payne Creek  wetlands discharge outfall,  excess water  will
be pumped through a pipeline across Doe  Branch  by low-pressure water
 pumps.  Beyond Doe Branch,  there  will be enough head  and capacity to
carry this water through  a ditch  system where water will flow by gravity
to the discharge weir adjacent  to  the Payne  Creek floodplain.
                                    2-66

-------
Once the water is in the ditch system,  it will  flow downhill  to  a
sheetflow control pond.  The water will  then  overflow a grass-covered
discharge sill developing sheetflow  into the  floodplain paralleling
Payne Creek.  There will be no discharge structures within  Waters of the
State associated with these items.

The discharged water will overflow this  grassed,  earthen bank,  and flow
into Payne Creek wetlands.  The pond overflow will  be designed  to keep
exit velocity low.  Once the effluent  enters  the  floodplain,  the
existing heavy growth or vegetation  should  retard the movement  of the
water within the floodplain and limit  the effluent  velocity (to  2 feet
per second or less).

In reviewing local  and  regional stream water  quality data,  it can be
expected that during certain conditions  most  streams will exceed one or
more Class III water quality standards.   Water  quality data for  Doe
Branch and Shirttail Branch have  shown exceedences  for alkalinity,
dissolved oxygen, cadmium, mercury,  iron,  zinc,  and pH.  Water  quality
data for Payne Creek have shown exceedences for  dissolved oxygen,
cadmium, mercury, and zinc.  Higher  than normal  metal concentrations are
most likely the result  of increased  metal  solubility caused by  natural
acidic and low oxygen level stream water quality conditions.  Although
violations of water quality standards  may occur  in  these systems under
certain conditions, they most  likely reflect  ambient/natural  background
conditions and are  not  the result of effluent water quality impacts.  If
a comparison between the expected concentrations  of the concerned
parameters in the proposed receiving stream and  CF's treated  process
discharge water are evaluated,  it can  be shown  that the receiving
streams may actually experience a net  positive  improvement  in overall
water quality.  CF's proposed  discharge is  not  expected to  contribute to
or cause violations of  Class III  water quality  standards.

As originally filed, CF Industries'  Application  for Development  Approval
called for the construction of two  surface  water outfalls that  would
                                        2-67

-------
 discharge clarified water to either Doe Branch and/or  Shirttail  Branch.
 It was determined that, from an environmental standpoint,  it would be
 desirable to provide an alternate discharge outfall  into a perennial
 system.   It was decided as described previously  that this discharge
 outfall  will sheetflow across wetlands into Payne Creek just north of
 Hardee Phosphate Complex II.  The utilization of this  outfall into Payne
 Creek  will  increase the flexibility of operation if  the experimental use
 of recycled water in lieu of fresh water in the  flotation plant  causes
 the  effluent water quality to exceed Florida's Class III water quality
 standards.   If this were to occur, surface water discharges could be
 limited  in  Shirttail Branch and Doe Branch.  Since,  at this point in
 time,  the quality of the process water could not be  guaranteed to meet
 regulatory  standards on a continuous basis, the use of these
 intermittent streams as receiving bodies could be restricted.  If water
 quality  standards are exceeded, the use of Shirttail Branch and  Doe
 Branch will be dependent on each having sufficient volume and flow to
 provide  the necessary mixing and dilution to meet water quality
 objectives.

 If the above  scenario were  to occur,  CF would weigh the positive
benefits  of using recycled  water against the resultant problems that
elevated  levels  of certain  water quality standards could have on
receiving waters.   Once these benefits and  impacts were evaluated, CF
would  either  decide  to continue using  recycled water, necessitating a
request  to  FDER  for  a mixing zone, or  to cease the experimental use of
 recycled  water  in lieu of  fresh water  in the flotation plant.

2.5.9.2   ADDITIONAL  WATER  DISCHARGE ALTERNATIVES
Since, as proposed,  a positive  water balance is  projected,  an acceptable
method to discharge  wastewater  will  be  required.   After an  assessment of
water  discharge  alternatives, discharge to  surface  water either  directly
or via wetlands  was  selected as the  preferred  option for CF.   Comments
regarding other  alternatives evaluated  are  presented below.
                                        2-68

-------
Connector Wells
A ground water discharge  method  was  precluded from use since an adequate
head differential between the  bottom of the mine cuts and the deeper
aquifers does not exist at  all locations.   However,  connector wells are
potentially  feasible,  from  a technical  perspective,  to discharge water
from the surficial  aquifer  to  the  deeper aquifers.  More detailed
studies may  be needed  to  determine the  feasibility of connector wells on
the site.

Deepwell Injection
A ground water discharge  technique was  rejected because the high initial
capital cost cannot be justified when compared to other alternatives.
This technique also has the potential risk of causing aquifer
contamination.

Zero Discharge
CF1s proposed projected positive water  balance precludes zero discharge.
In an attempt to comply with no  discharge, other negative factors such
as increased settling  areas, higher  dams,  impacts on post-mining
contouring and reclamation, and  future  land use potential would all
require further consideration.

                          2.6   RECLAMATION  PLAN
2.6.1  OBJECTIVES
The present  land use of CF  Industries'  Complex II mine site is primarily
palmetto prairie, freshwater marsh,  and hardwood forest (Table 2.1.5-1).
All of the mine site is designated as mining in Hardee County's Compre-
hensive Plan (Adley and Associates,  Inc.,  1980).  Approximately
14,925 acres of the site  will  be disturbed by mining and related activi-
ties (Table 2.6.1-1).  The  areas to  be  preserved consist of the U.S.  EPA
Category I-A wetlands (Figure  2.1-2).

The reclamation plan for  the site  is designed to meet the intent of
Florida DNR's nine  reclamation rules (Chapter 16C-16) and the goals of
                                        2-69

Hardee  County's  Comprehensive Plan and Hardee County Land Development
Code  (Article  IV).   Specific  objectives of the reclamation plan are to
restore the  disturbed  lands to beneficial uses that are compatible with
adjacent  land  uses  and  consistent with future land use plans; enhance or
restore as nearly as practicable the natural functions of the existing
important habitats,  water  and lands on the site;  eliminate safety
hazards; minimize erosion  and siltation effects of water leaving the
property; and  eliminate the visual imoacts of mining.   To achieve these
goals,  all of  the disturbed wetland and forest acreage will be replaced
and the majority of  the remaining disturbed lands will be reclaimed to
improved pasture.  CF's innovative sand/clay waste disposal technique is
an important aspect  of  the reclamation program since it reduces the
amount  of conventional  clay settling areas required, allows reclamation
to near original  grade, and produces reclaimed soils that are suitable
for future agricultural uses.

2.6.2   PHYSICAL  RECLAMATION OF LANDFQRMS
The land use capabilities  and  reclamation plans for the mined areas are
closely related  to the  types  of landforms created by the waste disposal
plan.   The acreage of each landform remaining after mining and waste
disposal is delineated  in  Table 2.6.2-1 and is summarized below:

2.6.2.1  SAND/CLAY MIX AREAS
CF Industries has been experiment ing with  the  sand/clay waste  disposal
technique since 1980.  This particular technique  significantly reduces
the time needed for stabilization of the waste  clays  and  will  allow more
rapid reclamation of these lands than could be  accomplished  with  con-
ventional clay settling areas.  This technique  also allows waste  dispos-
al materials placed above-grade to settle  at-  or  near grade, thereby
eliminating the need for high dams and allowing reclamation  to be
completed close to original contours.  Based on the favorable  results of
this experimental disposal technique, sand/clay mix will  be  the predom-
inant waste disposal method to be used on  the  site.   Additional
discussion of CF1 s experimental waste disposal  technique  is  provided  in
Section 2.4.

The sand/clay mix will be pumped to 26 storage areas  that will occupy
9,083 acres or 60.9 percent of the site  (Figures  2.4-1A and  2.4-1B).
The sand/clay mix will be pumped at approximately 30-35 percent total
solids with a dry weight sand/clay ratio of approximately 2:1. At  the
time of placement, the clay solids will  be 12  to  18 percent.   The
storage areas will be  filled  to an average height of  10  feet above
original grade and a maximum  of 5 feet below the  top  of  the  dikes.  The
mix will undergo an initial period of rapid subsidence and dewatering,
reaching approximately 30 percent clay solids  at  the  completion of
filling, followed by a prolonged period  of gradual consolidation  and
further subsidence.  Over a period of approximately 5 years  after
filling, the sand/clay mix is expected to  consolidate to  an  average of
approximately 41 percent clay solids.  This level of  consolidation  with
surface crust development is  expected to be sufficient to support
agricultural machinery (Garlanger, J984).

The natural slope of the sand/clay mix  is  approximately  one  foot  drop
across 1,000 feet of disposal area.  Therefore, the decant  end or
downs lope portion of the storage area will be  wetter  and  subject  to
                                        2-73

-------
ponding.   Differential  settling will also produce a slightly undulating
surface.   The  surface level of the storage area after subsidence Is
designed  to  average  approximately two feet above natural grade.

After  the  desired  level  of consolidation is achieved, the surrounding
dams and any protruding  overburden spoil piles will be graded over and
will partially cap the  sand/clay mix areas (Figure 2.6-1).  It is
expected that  the  volume of overburden within the surrounding dams and
remaining  spoil  piles could provide a two to four inch cap for the
sand/clay  mix  areas.  However, the thickness and extent of the cap will
vary with  the  aereal  coverage of the disposal area.  Naturally occurring
low areas  within each sand/clay disposal area are not planned to be
capped and would be  retained as low areas for wetland reclamation.
Additional grading and contouring will provide the necessary basins and
drainage channels  for the wetland reclamation program.

The sand/clay mix  and overburden soils used for capping are expected to
have good  potential  for  a variety of land uses, including improved
pasture, forestry, cropland and wetlands (Zeliars-Williams,  Inc., 1978;
Keen and Sampson,  1983).   The sand content  should improve tillage and
aeration problems  that are common with clay soils.   The content of silt
and clay provide water and nutrient retention and natural fertility.
The increased moisture retention capacities of the sand/clay mix have
the potential  for  causing high water levels or ponding.  This effect
would favor  the  reclamation of wetlands and should not preclude reclama-
tion of improved pasture.   This increased soil moisture, however, may
limit the  types  of crops  that  may be grown on the sand/clay mix soils.
Supplemental grading, drainage and the overburden cap on portions of the
disposal areaa would  increase  the range of cropping possibilities.

Since the  objectives  of  the reclamation plan include reclamation of
disturbed  wetlands and productive agricultural uses, the majority of the
sand/clay-mix areas will  be reclaimed to wetlands and improved pasture.
Revegetation methods  are  described in Section 2.6.4.

 On the average, the sand/clay storage areas will be  filled in approxi-
 mately one year.  Drying and consolidation to approximately A1 percent
 clay solids will require approximately 5 years.  Final grading and
 revegetation will require an additional 2 years.  Therefore, complete
 reclamation of the sand/clay storage areas will be completed in approxi-
 mately 7 years after filling is completed.

 2.6.2.2  SAND TAILINGS FILL AREAS WITH OVERBURDEN CAP
 Sand tailings will be  deposited in mine cuts and will occupy a total of
 2,213 acres (Figures 2.4-1A and 2.4-1B).  The mine cuts will be back-
 filled with sand tailings to approximately natural grade and capped with
 approximately 6 to 12  inches of overburden (Figure 2.6-2).  The over-
 burden cap will provide a soil  cover that will have improved agricultur-
 al characteristics compared to  the infertile sand tailings.  Sand tail-
 ings capped with overburden have good potential for improved pasture,
 forestry,  citrus,  cropland,  and residential/industrial construction
 (Zellars-Williams,  Inc.,  1978).   Recent  experimental plantings have also
 shown that  sand tailings  with no overburden cap are suitable for a
 variety of  forage  grasses (Mislevy and Blue,  1981).  It is planned to
 reclaim the capped sand tailings fill areas primarily to improved
 pasture, wetlands  and  upland forest.

 Since sand  tailings  dewater rapidly and  have good bearing capacity,
 capping with  overburden can begin almost  immediately after filling is
 complete.   Final grading  and revegetation will be completed within
 approximately 2 years  after  filling.

 2.6.2.3 LAND-AND-LAKES
 Lakes  will  be  constructed  in five  mined out  areas  on the  site
 (Figures 2.4-1A and  2.4-IB).  Sand tailings  or sand/clay  mix will  not be
 available  for  reclaiming  these  areas,  therefore,  reclamation will
 consist  primarily  of grading the remaining  spoil  piles  followed  by
 revegetation.   A conceptual  diagram of  the  land-ahd-lakes reclamation is
shown on Figure 2.6-3.  The  planned surface water  area  within each

Suggested  lake shapes are  shown  on Figures 2.6-4 and 2.6-5; however, the
actual size and shape of the  lakes will depend on variables such as the
remaining  spoil pile configuration, direction of mine cuts and the void
space available.   These  lake  shapes include islands that provide refuge
for waterfowl and  wading birds,  a  variety of sizes and shapes for
aesthetics, and peninsulas for increased shoreline length and access
points.

Double spoiling will be  utilized in the larger mined out areas where it
would be advantageous to maximize  the width of  islands, peninsulas and
open water.  A variety of shoreline slopes will be created but at least
25 percent of the  lake areas  at  high water will consist of a littoral
water zone for emergent  vegetation and habitat  for a variety of wild-
life.  A shallow water zone will also be constructed that will occupy 20

 depth of 6  feet below  annual  low water  levels and  shall have  shoreline
 slopes no steeper than 4:1  (Figure  2.6-3).

 It is planned to reclaim the  land surrounding the  lakes to  pine  flat-
 woods and hardwoods (Figure 2.6-4 and 2.6-5).   Management of  these  lands
 will  be primarily for recreation and wildlife  habitat.

 Reclamation of the  land-and-lakes areas will  require approximately  2
 years,  allowing  one  year for grading and one  year  for revegetation.

 2.6.2.4   OVERBURDEN  FILL AREAS AND  DISTURBED  NATURAL GROUND
 The mined  and  disturbed areas to be reclaimed  with overburden fill  will
 occupy  1,230 acres,  not including the overburden fill to be used in
 reclaiming  the land-and-lakes areas or capped  sand tailings fill areas.
 These areas  are  primarily located along the property boundary and also
 include the  plant site  and  Initial Settling Area, Compartment I
 (Figure 2.1-1).  The  unmined areas along the property boundary may be
 disturbed  for  utility corridors,  access  roads, pipelines,  recirculating
 water ditches  and other related mining activities.  These mined and
 disturbed  lands  will  be reclaimed to- approximately natural grade and
 will have good potential  for a variety of land uses, including improved
 pasture,  forestry, citrus,  cropland  and  residential/industrial
 construction.

 Reclamation  of overburden fill areas can begin immediately after mining.
 These areas  will generally  be reclaimed  within two years,  allowing one
 year  for grading and  one  year for revegetation.

2.6.3  WETLAND AND STREAM'CHANNEL RECLAMATION
2.6.3.1  WETLANDS
Approximately  24 percent  qf the site consists  of forested  and  non-
forested wetlands (Table  2.1.5-1).   All  of this wetland  acreage  will be
reclaimed, as  required  under Florida DNR mine  reclamation  rules  (Chapter
                                        2-82

-------
16C-16).  Although the topography  of  the  reclaimed site will be within
2 or 3 feet of original grade,  it  will  not  be possible to restore all of
the wetlands to their original  shape  and  location.  Several large mined
out areas will need  to be  reclaimed to  land-and-lakes, and each sand/
clay mix disposal areas will have  a slightly  higher elevation near its
inlet, which would be more  suitable for upland land uses.

A conceptual plan depicting  the location  of reclaimed wetlands is shown
on the post-reclamation land use map  (Figures 2.6-4 and 2.6-5).  This
conceptual land use map shows  the  planned reclaimed wetland acreage and
the intended distribution  of wetlands over  the entire property.  It
should be noted, however,  that  the actual shape and location of the
reclaimed wetlands will likely  be  different than  that shown on the
drawing.  For instance, the wetlands  reclaimed at the low end of each
sand/clay mix disposal area are typically shown as one large contiguous
unit with a fairly smooth  boundary.   Differential settling in the
disposal areas may create  several  separate  low areas with very irregular
boundaries which can be an  advantage  since  they would provide more edge
effect between habitat types.   Naturally  occurring irregular boundaries
are not planned to be recontoured.  The only  natural low areas that
would probably be recontoured and/or  filled would be the occurrence of
many small depressions throughout  the sand/clay disposal areas which
might significantly hamper  future  agricultural activities.  This
recontouring would not reduce the  planned acreage of reclaimed wetlands.

Approximately 25 to 30 oercent  of  each  sand/clay  mix area is planned to
be reclaimed as wetlands.  This acreage will  be created primarily by
raising the elevation of the outlet drain after consolidation and by
retaining a portion of the  oerimeter  dike along the lower end of the
disposal area.  Approximately 20 percent  of the land-and-lakes areas
will be reclaimed as wetlands.  Most  of the wetlands in those areas will
be created by grading and  contouring  the  required littoral zone within
the lakes.  The remainder  of the reclaimed  wetland acreage will be
distributed within the areas to be reclaimed  with sand tailings and
                                       2-83

overburden.  Wetlands within these areas will be principally graded or
excavated in Low areas and along planned drainageways.  Revegetation  of
wetlands is discussed in Section 2.6.4.

2.6.3.2  STREAMS
The mine plan for the Hardee Phosphate Complex II includes  the raining of
several small ephemeral tributaries and portions of some  named streams.
The named streams that will be partially mined are Shirttail Branch,
Plunder Branch, and Coon's Bay Branch.  These streams also  have  several
ephemeral tributaries that will be mined.  The other  ephemeral streams
to be mined on the site are tributaries of Horse Creek, Brushy Creek,
Lettis Creek and Doe Branch.  The location of these streams and  their
existing drainage basin boundaries are shown on Figures 2.6-6 and
2.6-7.

CF is planning to mitigate the environmental effects  of mining these
streams through the following measures:  reclamation  of all adjacent
disturbed lands; reclamation of all disturbed main  stream channels  to
their approximate original grade; approximate restoration of original
drainage basin area; and  implementation of certain  precautionary
measures to prevent degradation of downstream waters.  The reclaimed
drainage basin boundaries  and drainage patterns are  shown on
Figures 2.6-8 and 2.6-9.

CF is currently raining and reclaiming  portions  of Hickey  Branch  at  the
existing Hardee Phosphate  Complex I operation,  approximately  3 miles
north.  It is anticipated  the reclamation of  this  stream  will  provide
relevant experience and design parameters  for construction of  the  stream
channels on the proposed mine site.

the suitability of these mine  soils  for  various  agricultural  crops and
native vegetation has not been well  established  through field experience
(Robertson, 1984) .  Therefore, CF  Industries  is  planning an experimental
revegetation program on an existing  sand/clay disposal  area at their
Hardee Phosphate Complex I.  The results  of  this  test  program and  other
similar research  in the Florida phosphate industry will be  used  to
determine the most suitable  agricultural  and  native species to be
planted on the sand/clay soils.

The existing sand/clay mix test area encompasses  approximately 140 acres
and is located in Section 7, Township 33S, Range  24E,  0.5 miles  south of
CF's Hardee Phosphate Complex  I plant site.   Filling of this  sand/clay
disposal area began in October, 1980 and  was  completed  in September,
1983.  The construction of this disposal  area and the  characteristics of
the sand/clay mix are very similar to that to be  used  on the  Complex II
mine site.

It is planned to  test a variety of upland and wetland  revegetation
techniques on the sand/clay mix test area.   Personnel  at the  University
of Florida Extension Service,  Soil Conservation  Service, University of
Florida Center for Wetlands, Florida Division of  Forestry,  and other
qualified agencies or individuals  are planned to  be consulted in design-
ing the experimental plantings.  Since the majority nf  the  Complex II
site will be reclaimed to wetlands,  forest land,  and agricultural  uses,
the emphasis of the experimental revegetation program  will  be on
reclamation of these vegetation types.

CF Industries is also conducting an  experimental  wetland reclamation
project at the Hardee Complex  I, approximately 0.5 miles north of the
plant site.  This wetland project  site is approximately 15  acres and has
been constructed on sand tailings  and overburden fill  that  has been
capped with one foot of sand/clay  mix.  The  area is planned to be
reclaimed as a hardwood swamp.  Specific  objectives of the  project are:
                                       2-89

-------
 (1) test the success of various combinations of  species diversity,
 (2) test the effectiveness of an artificial hardpan  to perch water,
 (3) test the benefit of various topsoil applications, and (4) test
 effectiveness of water control.  It  is expected  that the results of this
 project will also be of value in reclamation of  wetlands at the
 Complex II mine site.

 Presented  in the  following sections are CF's current revegetation plans
 for the Complex II mine site.  The actual species to be planted and
 planting methods  may be changed in later years to reflect the results of
 the experimental  revegetation program and reclamation research currently
 being conducted  in the  phosphate industry (Florida Institute of
 Phosphate Research,  1983b).

 2.6.4.2  IMPROVED PASTURE
 Improved pasture  will be planted as the initial vegetative cover on
 approximately 6,659  acres  of  the reclaimed site.  This initial planting
 of  forage grasses  will  be  established on portions of all  upland land-
 forms and would be  the  dominant  vegetation type on the reclaimed site
 (Table  2.1.5-1 and Figures 2.6-4 and  2.6-5).

 Improved pasture  was  chosen as  the  dominant  post-reclamation land use
 for the  following  reasons:  (I)  reclaimed  grazing land is in demand
 among local  cattlemen and  is  a  productive  agricultural use for mined
 lands (Hawkins, 1983; Miller, 1983);  (2)  planting of forage  crops is an
 excellent method  or  stabilizing  reclaimed  soils and  preventing erosion;
 (3)  the establishment of pasture sods is  an  excellent means  of encourag-
 ing the development  of  organic matter content  of soils which improves
 tillage properties,  aeration, nutrient  retention and moisture  retention
 (Cellars-Williams,  Inc., 1980);  and (4)  improved pasture  is  a  vegetation
 type that can be  easily cleared  and converted  to cropland  or alternative
uses if desired.
                                        2-90

-------
The forage species  to  be  planted  will  contain a rapidly germinating
annual grass  that will  quickly  provide an  initial  ground cover (where
erosion control  is  important),  a  long-lived  perennial legume and one or
two long-lived  perennial  grasses  for  the  permanent vegetative cover.
Inclusion of  a  legume  is  intended to  reduce  the need for refertilization
with nitrogen since  legumes  are nitrogen  fixing plants.

The particular  grass and  legume species to be planted will be carefully
selected to match the  characteristics  of  the surface soil type.   Unless
experimental  plantings  or additional  research in the phosphate industry
identifies more  suitable  forage varieties, the species to be planted
will be those currently used in reclamation  programs and suggested by
the Soil Conservation  Service  (1977)  or County Extension Service.
Recommended seeding mixtures vary with the season  in which they will be
planted and with the drainage  characteristics of the soil.  Permanent
grasses that  are typically planted are Ona stargrass, improved bermuda
grasses, and  bahia  grasses such as Pensacola, Paraguay, and Argentine.
Clover, hairy indigo,  and aeschynomene are recommended legumes;  rye
grass and millet are recommended  temporary grasses.

A seedbed for all pasture areas will  be prepared through final grading
or heavy discing.  Lime and  fertilizer will  be applied according to soil
test recommendations.

All unproved  pasture will  be protected from  grazing  until the forage
plantings are firmly established.   Replanting and  possibly refertiliza-
tion will be  conducted where initial  revegetation  fails or where
survival is poor.

2.6.4.3  FORESTED UPLANDS
Approximately 3,400 acres  of reclaimed uplands, occupying 23 percent of
the site, will be revegetated as  forest land.  These forested areas will
be planted primarily within  the land-and-lakes areas, along the
reclaimed dams of the  sand/clay mix areas, and as  greenbelts along the
                                        2-91

-------
 property boundary.  The greenbelts and contiguous  forested atrip plant-
 ings would provide habitat for wildlife, corridors  for wildlife move-
 ment,  eventual shade for cattle and would also serve as an aesthetic
 break in the landscape.

 The  forested uplands will consist of approximately one-half mixed hard-
 wood plantings and one-half coniferous plantings (Table 2.1.5-1 and
 Figures  2.6-4 and  2.6-5).  The ratio of hardwood forest area to coni-
 ferous forest area was decreased from that which currently exists on the
 site because the coniferous species are expected to be more marketable
 in the future.  The site also probably contained much more coniferous
 forest prior to logging in the early 1900's.

 The  hardwood forest areas will be planted with a variety of native tree
 species  such as laurel oak, live oak,  dogwood and sweetgum.  Biackgura,
 water  oak,  and red maple or other suitable species would be planted
 adjacent  to  lowland areas or  along drainages where the soil may be more
 poorly drained.   The actual composition of planted seedlings will depend
 on the availability of various species from the State Forestry Depart-
 ment  and  commercial nurseries.  Bare root,  potted or containerized
 seedlings  will be  planted in  a random  pattern to yield an initial
 density  of 400 trees per acre in order to ensure a final density of 200
 trees  per  acre.

 The  coniferous forest  land will be planted  and managed to eventually
 resemble  a pine flatwoods community rather  than a commercial pine
 plantation.   South Florida slash pine  and longleaf pine seedlings will
 be hand-planted in a random pattern at a density of 400 trees per acre
 in order  to  ensure a final density of  200 per acre.  Efforts will be
 made to  establish  native understory species such as gallberry,  wire
 grass  and  small  scrub  oaks.

A ground cover  of  short-lived  herbaceous species will be planted on
 reclaimed  forest  land  where erosion and sediment control is important,
                                        2-92

-------
such as along reclaimed stream channels.   The  selection of herbaceous
species and timing of planting will be done  carefully to reduce  the
potential problem of competition between  the tree  seedlings and  ground
cover.  Eradication of agressive volunteer species  or replanting of
seedlings may be required to achieve  a final density of 200 trees per
acre.  All forested areas will be  protected  from grazing until  they are
firmly established.

2.6.A.4  FORESTED WETLANDS
Approximately 1,410 acres of freshwater swamp  will  be reclaimed  on the
site (Table 2.1.5-1 and Figures 2.6-4 and 2.6-5).   Most of these fresh-
water swamps will be contiguous with  the  reclaimed  stream channels and
reclaimed freshwater marshes.

A variety of revegetation techniques  for  wetlands  are currently  being
tested in the Florida phosphate industry  (FIPR,  1983a).  Although many
projects are only a few years old,  the results of  several techniques are
encouraging.  It is expected that  additional research will suggest even
more effective approaches by the time CF  begins  to  reclaim its  first
wetland (in approximately mine year 5).   CF's  current plan for  reclaim-
ing wetlands will consist primarily of creating  a  topography with
frequently saturated soils, providing a favorable hydroperiod,  spreading
a layer of organic mulch borrowed  from another wetland, and tree
planting.

The  freshwater swamps will be planted with a variety of native  tree and
shrub species such as red maple, black gum,  water hickory, sweet bay,
water ash, sweetgura, buttonbush, dahoon and  wax  myrtle.  Bare root,
potted or containerized seedlings  will be planted by hand in a  random
pattern to yield an initial density of 400 trees per acre in order to
ensure a final density of 200 trees per acre.  Planting herbaceous
species for erosion control and maintenance  of newly established vegeta-
tion will be similar to that described  for the upland hardwood  forest.
                                        2-93

-------
 2.6.4.5  NON-FORESTED WETLANDS
 Approximately 2,470 acres of freshwater marsh will be reclaimed on the
 site.   The number of reclaimed marshes will be less than the number
 presently on the  site but the total acreage reclaimed will be increased
 by  131  acres.   Most of these marshes will be reclaimed in the lower
 portions  of the reclaimed sand/clay mix areas (Figures 2.6-4 and 2.6-5).
 These  lower wet areas will occur at the outlet end of the storage areas
 and  in  areas of differential settling.  Additional basins and channels
 will be excavated if needed to create the proposed acreage of reclaimed
 wetlands.

 The current  revegetation  plan for  these marshes is to spread a mulch
 borrowed  from  another wetland that is dominated by desireable native
 wetland vetetation.   This technique has been shown to be a successful
 revegetation method  for marshes  on several  mine sites in central Florida
 (Carson,  1983;  Clewell, 1981;  Conservation  Consultants,  19R1).  CF's
 experimental revegetation plots  and further research by  others may
 provide additional  successful  revegetation  techniques that  may be
 incorporated.

 2.6.5   RECLAMATION  SEQUENCE
 Reclamation  will  lag  several years behind the mining schedule because of
 the time required for  dam construction, filling the mining  cuts  with
waste materials,  consolidation of  the sand/clay mix,  grading and
contouring,  and revegetation.  The total  time period for mining  and
reclamation  ranges  from 3  to 4 years  for  overburden and  sand tailings
areas,  to  10 years  for sand/clay mix  areas.   Presented below is  a
 summary of  the  projected  time  requirements  for mining and reclamation of
a typical  parcel  to be mined in  any given year.

                            Land-and-Lakes,

                             3-4  years                 10 years
The reclamation  sequence  for each  sand/clay disposal area is presented
in Table 2.6.5-1.
Mining of the proposed  tract  is  expected  to  require  approximately 27
years.  Reclamation of  all mined  lands  will  be  completed within eight
years after mining ends.  The  progress  of mining and reclamation activi-
ties across the property at years 10, 21, and 27 is  shown on
Figures 2.6-10 through  2.6-15.   The  proposed reclamation schedule for
the tract for each year is presented  in Table 2.6.5-2.

2.6.6  POST-RECLAMATION TOPOGRAPHY
An objective of the reclamation  plan  is to restore the  land surface
elevations to approximate original grade, to the greatest extent
practical.  All of the  site is planned  to be reclaimed  within 2 to
3 feet of original grade, with the exception of the  mined-out areas to
be reclaimed as lakes.

Sand/clay mix areas will be gently sloping flat areas with low areas
near the outlet and randomly occurring  depressions which are a result of
differential settling.  The retaining dams will be graded towards the
interior and will provide a thin  cap of overburden material in a band
around each disposal area.  The areas between sand/clay mix areas will
be graded flat in cross-sections  and will be at approximate pre-mining
slopes and elevations.  Several of the  reclaimed stream channels will be
established in these areas.

The post-reclamation drainage area boundaries will vary slightly from
existing boundaries because of the location  of  the sand/clay mix areas
(Figures 2.6-8 and 2.6-9).  However, total acreage of each drainage
                                        2-95

 basin will be approximately equal to pre-mining conditions
 (Table 2.6.6-1).

 2.6.7  POST-RECLAMATION LAND USE
 Agriculture  will be  the predominant  land use of the reclaimed site,
 occupying  approximately 6,700 acres  or 44 percent of the total property
 (Table  2.1.5-1  and Figures  2.6-4 and 2.6-5).  This economic use is
 compatible with adjacent properties  and is consistent with the goals and
 policies of  the Hardee  County Comprehensive Plan.  All of agricultural
 land  will be  initially  planted as improved pasture, although it is
 anticipated  that  these  lands  would also be suitable for a variety of
 agricultural  crops and  other  land uses. CF's planned experimental test
 plots would evaluate  a  variety of crops that may be planted in later
 years.

 The remainder of  the  reclaimed site  will consist primarily of forest
 lands and wetlands (Table 2.1.5-1 and  Figures 2.6-4 and 2.6-5).  These
 vegetation types  currently  occupy approximately 45 percent of the site
 and provide valuable  environmental functions, such as maintaining water
 quality of downstream waters  and providing habitat for a variety of
 wildlife.  Therefore, all of  the existing acreage of forest lands and
 wetlands will be  replaced and  will actually be increased by
 approximately 10  percent.

 The only existing land  use  type  that will  be significantly reduced in
 acreage through mining  and  reclamation  is  the palmetto prairie.  This
 vegetation type  will  be  largely  replaced by improved pasture which will
 provide much better forage  for cattle.   Palmetto competes with forage
grasses and is  commonly  eradicated on cattle ranges.  Therefore,  this
vegetation type may have eventually  been cleared on the CF property even
 if the site were  not  mined.

                     3.1  THE AFFECTED ENVIRONMENT
3.1.1  INTRODUCTION
The proposed mine  and  beneficiation plant  at  the CF Industries Hardee
Phosphate Complex  II site will  be  located  a  few miles northwest of
Wauchula in Hardee County,  Florida.  The  proposed activities have the
potential to generate  air emissions during the  initial  construction as
well as during  the 27-year  life of the raining operation.   These
emissions may be fairly  insignificant since  actual processing of the
phosphate ore will be  done  at an existing  off-site plant.   Activities
which may result in the  production of emissions include:
     1.  Initial land  clearing  and preparation  (particulates from earth-
         moving and combustion  products due  to  open burning and heavy
         equipment traffic);
     2.  The mining process (particulates);  and
     3.  Increased vehicular  activity.

These sources are  relatively minor in magnitude or occur  infrequently
for a short duration.

In order to assess the potential impact of the  proposed mine and benefi-
ciation plant, baseline  conditions for meteorology and  air quality must
be assessed.  An air quality  and meteorological monitoring program was
implemented by CF  in September  of  1975.  The  program included a weather
station, 7 rainfall stations, 8 fixed air  monitoring stations, and
5 mobile air monitoring  stations.   The mobile stations  were operated in
1976 and 1977 and have been discontinued due  to the remoteness of the
area from existing operations and  the low  pollutant levels recorded.
The station locations  are illustrated in Figure 3.1-1.

This section presents a  description of the local meteorology of the site
area, applicable air quality  regulations,  existing and  planned emission
sources which may impact the  site  area, and  air quality measurements
obtained at Che Hardee Phosphate Complex II  site.  Rased  on existing and
gathered information, estimated baseline air  quality levels are
presented.

3.1.2  REGIONAL METEOROLOGY
The Hardee Phosphate Complex  H  site  has  a relatively sub-tropical
climate which  is  typical of central Florida.   Winters are generally
quite mild and dry, with occasional cold  fronts  from the north.   Summers
are hot and humid, with fairly  regular  afternoon thunderstorms.   Central
Florida is characteristically humid as  a  result  of frequent  rainfall,
warm temperature, and occasional  cloud  cover.  Humidity levels are
usually highest  in the early  morning  and  lowest  in the afternoon.
Tropical storms accompanied by  heavy  rains may occur in the  summer and
early fall.  Tornadoes may be associated  with  some thunderstorms and
tropical disturbances.

3.1.2.1  METEOROLOGICAL DATA  SOURCES
The nearest weather station to  the Hardee Phosphate Complex  II site
recording temperature and precipitation is located about 2 miles north
of Wauchula, Florida.  Table  3.1.2-1  shows the monthly and annual
average temperature recorded  in Wauchula  and  at  the CF site.   Wauchula
records are based upon observations taken from 1941 to 1970.   CF data
are for 1981.

3.1.2.2  TEMPERATURE
The 30-year annual average temperature  in Wauchula is 72.4°F.   The maxi-
mum monthly average temperature  (81.6°F)  occurs  in August, whereas the
minimum monthly average temperature (61.8°F) occurs in January.   For the
CF site, the annual average temperature for 1981 was 68°F, with  a maxi-
mum monthly average temperature  of 80°F occurring in July and  August and
a minimum monthly average temperature of  56"F  occurring in February and
December.

3.1.2.3  PRECIPITATION
Monthly and annual average rainfall data  from  Wauchula during  the period
from 1941 to 1970 and the Hardee  Phosphate Complex II site for 1981 are
shown in Table 3.1.2-2.  The  annual average rainfall in Wauchula is
                                3-3

 54.7 inches, whereas  the maximum monthly rainfall  occurs in July,  with
 9.04 inches, and  the  minimum monthly rainfall occurs in November with
 1.63 inches.  For  the  stations  at  the  CF site,  the annual  average  rain-
 fall for 1981 ranged  from  approximately 33  to 44  inches, with maximum
 monthly rainfall occurring  in August,  and minimum  monthly  rainfall
 occurring in April  for most  of  the  stations.

 3.1.2.4  WIND DIRECTION AND  SPEED
 Winds in central Florida are  dominated  by the sub-tropical  conditions
 that produce easterly and southerly  winds.  The most  common winds  on  an
 annual  basis in this area are between northeast and  south.   Five-year
 (1971-1975)  annual and seasonal  average  wind  roses  for  Tampa Inter-
 national Airport (TIA) are presented in  Figures 3.1-2 and 3.1-3,
 respectively.   The National Weather  Service station  at  TIA  is  the  near-
 est  to  the  site  and the roost  representative primary  weather station for
 which long-term  weather data are available.   Annual  average and  seasonal
 average  wind roses for 1981 for  the CF site are illustrated in
 Figures  3.1-4 and  3.1-5,  respectively.   As shown in  these figures, the
 annual  average wind directions measured  at both sites reflect  strong
 easterly and westerly  components.  The  annual average wind  directions
 measured at  the  NWS station at TIA are  predominantly  from the  east-
 northeast through  east- southeast and west,  whereas those at the CF site
 are  from the north through  east-northeast, southeast, and west.  The
 differences  in wind directions measured between the two  sites  can be
 attributed  in part  to  the  relative locations of the sites with respect
 to the Gulf  of Mexico  and  the Atlantic  Ocean,  and  the non-coincident
 time periods for which wind data were available for comparisons.

 3.1.2.5  ATMOSPHERIC STABILITY
Atmospheric  stability  is an evaluation  of the  dispersive capacity of the
 atmosphere and is  used  to determine  the  potential  concentration of
 pollutants.  Turner (1964)  developed stability classes which range
 from A (very unstable)  to F  (stable).  As the  atmosphere becomes more
stable,   its  dispersive  capacity  decreases and  the  dissipation of
pollutants is reduced.  The  relative frequency of occurrence of each
stability class  at  the NWS  station at TIA, based on 43,824  hourly

 observations  over  a 5-year period from 1971 to 1975 (NOAA, 1975), is
 presented  in  the  following list:
      Stability  Class
      A  - very unstable
      B  - moderately unstable
      C  - slightly  unstable
      D  - neutral
   E,F  - slightly  stable,  stable
Frequency of Occurrence
      0.4 percent
      6.0 percent
     15.6 percent
     37.8 percent
     40.2 percent
Conditions  at  the Hardee  Phosphate Complex II site are expected to be
similar  to  the  conditions experienced at Tampa, due to the proximity of
the two  sites.   Slightly  lower  wind speeds and a slight increase in
unstable conditions  (A,B,C)  may be expected at the CF site due to its
inland location  compared  to  the NWS station at TIA.

Atmospheric  temperature inversions alter the dispersive and mixing
capacity of  the  atmosphere and  limit  the volume of air into which
emitted  pollutants can mix.   The most frequent inversions occurring at
the site are due to  the radiative cooling of the surface  on clear and
calm nights, called  nocturnal or radiation inversions. The most severe
radiation inversions occur during the fall and winter, but are usually
dissolved by surface heating shortly  after sunrise.

Other types of  inversions  that  occur  at  the site are  due  to frontal
systems and subsidence inversions.  A frontal system  may  cause a build-
up of pollutant  concentrations  for  a  few hours,  but these systems are
experienced infrequently  and only during the late fall or winter when
cooler air masses invade  the state.   A subsidence inversion is formed
when a stationary high pressure area  causes air at high levels to slowly
descend,  creating an upper air  inversion.   Unlike nocturnal inversions
which are broken up by sunshine,  subsidence inversions, resulting from
high pressure areas, may  persist  for  days.  A study by Holzworth (1972)
showed that occurrences of mixing heights  of less than 1,500 meters on
at least  2 to 5 consecutive  days  with wind speeds of  less than
                               3-11

-------
4.0 meters per  second,  representative  of  stagnation conditions,  are
expected  infrequently  near  the  site.   Stagnation conditions  lasting at
least 2 consecutive days  occurred  about  9 times,  whereas  stagnation
conditions lasting at  least  5 days did not occur over a 5-year  period.
Stagnation estimates are  based  on  data collected at Tampa,  the  nearest
NWS station to  the proposed  site included in the Holzworth  study.

3.1.3  APPLICABLE AIR QUALITY REGULATIONS
3.1.3.1  AMBIENT AIR QUALITY STANDARDS (AAQS)
Federal and State of Florida AAQS  applicable to the proposed  project
site are shown  in Table 3.1.3-1.   Pollutants for which AAQS  have been
set are termed  "criteria" pollutants.   Federal AAQS were  set  by  EPA to
protect the public health and welfare  (i.e., animals, vegetation,  soils,
materials, etc.) with an  adequate  margin  of safety.

Florida AAQS are equal to or, in the case of sulfur dioxide,  more
stringent than  federal AAQS.  EPA  promulgated  secondary annual  and
24-hour sulfur  dioxide AAQS  in  1971, but  revoked these standards in
1973.  The State of Florida, however,  retained these secondary  standards
as the state AAQS.

3.1.3.2  PREVENTION OF SIGNIFICANT DETERIORATION (PSD)
The Clean Air Act was amended in August  1977 (Public Law  95-95)  to
incorporate provisions for PSD.  Final PSD regulations were  promulgated
by EPA in August 1980 (45 FR 52735) and  require that state  implementa-
tion plans be revised to  include requirements  which will  prevent signi-
ficant deterioration of air  quality in areas which  meet the  ambient air
quality standards.  Major new sources  and major modifications are
required Co undergo PSD review.  A new source  is termed major if it has
the potential to emit  100 tons  per year  or more of  any regulated
pollutant and belongs to  one of 28 specified source categories,  or if it
has Che potential to emit 250 Cons per year or more of any  regulated
pollutant.

 Florida DER was granted federal PSD review authority by EPA on
 November 22, 1983 (Federal Register).  As a result, federal PSD permits
 are now issued by Florida DER.  EPA has previously determined that the
 CF Industries Hardee Phosphate Complex II does not require a PSD
 permit.

 Florida DER has also promulgated state PSD regulations which are nearly
 identical  to the  federal PSD regulations.   The proposed CF Complex II
 would  not  require a state  PSD permit under these regulations.

 3.1.3.3  NOW-ATTAINMENT  AREAS
 EPA has  promulgated  a list  of areas of the. country which are not
 currently meeting  federal AAQS (EPA,  1981, 40 CFR,  Part 81).   These
 areas are termed  non-attainment  areas  and  require special  stringent
 permitting conditions  for new sources  which  are located in or have the
 potential to significantly  impact  these areas.

Non-attainment  areas  for the  federal AAQS  for  PM, S02,  ozone  and N02
which are in the vicinity of  the CF site are  as follows:
     • PM—the nearest non-attainment  area for  PM is described  as  "that
       portion of Hillsborough County  which  falls within the  area  of  a
       circle having  a centerpoint  at  the  intersection  of  US 41  and
       State Road 60 and a radius of 12 km"  (43 PR  8962).   The boundary
       of this area is approximately 45 km northwest of the CF site.
     • 802—tne nearest non-attainment  area  for S02 is  described as
       being "the northwest corner  of Pinellas  County." This area  is
       approximately 100 km from the CF site.
     • Ozone—the nearest non-attainment area for ozone is designated  as
       being all of Hillsborough County, its borders being 6-8 km  from
       the  CF site.  Florida DER has requested  that Hillsborough County
       be redesignated as an attainment area for  ozone.
    •  N02—Florida is currently unclassified for
                               3-14

-------
The proposed plant  site,  therefore,  is  in an area designated as attain-
ment or unclassifiable  for  all  pollutants.

3.1.3.4  EMISSION STANDARDS
AIL sources of pollution  are  required  to  meet  state and federal emission
standards.  For  the  proposed  mining  operation  and beneficiation plant,
no federal or state  emission  standards  apply.   However, according to
FAC, Chapter 17-4,23(l)(d), all  new  sources  must  use the best  and latest
technology in order  to  be granted  an operating permit.   Fugitive
particulate matter must be minimized through reasonable precautionary
measures [FAC, Chapter  17-2.610(3)]. New stationary air pollution
sources must complete an  air  pollutant  source  construction permit
application (FAC, Chapter 17-4.03) and  receive a  construction  permit
before construction  of  the  facility  can begin.

3.1.4  AREAWIDE EMISSION SOURCES
Current emission sources  in the  central Florida region  are summarized by
EPA (1978) in the Central Florida  Phosphate  Industry Areawide  Impact
Assessment Study, which includes emission information for Hillsborough,
Polk, Manatee, Hardee,  Sarasota, DeSoto,  and Charlotte  Counties.
Information from this report  is  reproduced  in  Table 3.1.4-1.

3.1.4.1  PARTICULATES
Dust and particulates are produced by  phosphate mining  and production
activicies.  Hillsborough County is  responsible for 39.1 percent (20,774
metric tons per year) of  all  particulate  emissions in the 7-county study
area.  Polk County produces 36.4 percent  (19,326  metric tons  per year)
of all particulate emissions.  The remaining counties have small
contributions to the areawide particulate levels  and have little or no
phosphate activity.

Sulfur dioxide is mainly  produced  by electric  utility.operations in
central Florida but  is  also associated  with  phosphate processing.
Eighty-two percent (241,344 metric tons per  year) of the SC>2 emissions

Overall, the ambient  levels  of  dust  and  S(>2  are  expected  to  increase
in the 7-county study area between 1976  and  2000.   The 1976  fluoride
emissions by the phosphate industry  were reported  to  be 315  metric
(346 short) tons.  This  level is  not  expected  to change much before
2000.

produced  in the EPA 7-county  study  area  are  from Hillsborough  County.
Most of these emissions  can be  attributed  to electric  generating
facility  point sources.  Polk County comprises  15.6  percent  (45,981
metric tons per year) of the  total  areawide  SC^  emissions.   Very
little S(>2 is emitted in Hardee, Manatee,  Sarasota,  DeSoto,  and
Charlotte Counties.

3.1.4.2   FLUORIDES
Fluoride  emissions are produced  from phosphate  processing.   It  is
estimated that 315 metric  tons of fluoride emissions were generated by
the phosphate industry in  central Florida  in 1976  (EPA,  1978).   These
levels are expected to remain fairly constant  in the ensuing 20  years.

3.1.4.3   NITROGEN OXIDES
Nitrogen  oxide emissions are  a by-product  of fossil  fuel combustion and
are related to fuel-burning activities.  Point  source  emissions  are
produced  primarily from  electric power generating  facilities and
phosphate plants in central Florida.

3.1.5  AMBIENT AIR QUALITY DATA
As discussed in Section  3.1.1, CF has gathered  ambient air monitoring
data at the Hardee Phosphate  Complex II  site since September 1975.  The
locations of the air monitoring  stations are shown in  Figure 3.1-1.
Tables 3.1.5-1 through 3.1.5-3 summarize the collected ambient data for
total suspended particulate matter  (TSP),  sulfur dioxide (802),  and
gaseous fluorides (F), respectively, for the years 1976  through  1981.
These data are from the  fixed CF monitoring  stations,  Stations AQ-1
through AQ-8.  Data from the mobile monitoring  stations  AQ-9 through
AQ-13, are not presented because these data  were collected  inter-
mittently and over only  a  1.5-year  period  in 1976  and  1977.

Effective January 1, 1986, CF modified its ambient air quality
monitoring program after generating a 10-year data base.   In this
revised program, the ambient  air is monitored  at Station AQ-2.   This
station monitors for TSP and  is  located  at Hardee Phosphate  Complex  I  in
the general area of mining activity.

 3.1.5.1  TOTAL SUSPENDED PARTICULATES
 Table 3.1.5-1 shows that data recovery for TSP was acceptable for  all
 stations and all years.   Data were collected on a once-every-sixth-day
 schedule, resulting in about 60 observations per year.   Annual  geometric
 mean  TSP levels are generally low for all stations for  roost  years  and
 reflect background, rural TSP levels.

 All TSP annual  geometric means are less than 35 ug/m3 except  for
 Stations  AQ-1 and AQ-3 in 1981; Station AQ-4 in 1980; and  Station* AQ-7
 in  1980 and  1981.   All annual geometric means are less  than  the Florida
 AAQS  of 60 ug/m3.   Over  the  6-year monitoring period, five 24-hour
 concentrations  in excess of  the 150 ug/m3 Florida AAQS  were  recorded.
 The causes of the  high values are not known, and judging  from the
 remainder of the data  base,  can be attributed only to local  phenomena
 such  as agricultural operations,  open burning,  or forest  fires.  The
 Florida 24-hour  AAQS for TSP can be exceeded once per year at each
monitoring station, and  the  data show that the  second highest 24-hour
 observation  at each station  was below the 150 ug/m3 level.  Therefore,
 no violations of the TSP standard were recorded  over  the monitoring
 period.

 3.1.5.2   SULFUR  DIOXIDE
 Table 3.1.5-2 presents SO2 data measured at  the  CF Hardee  Chemical
 Complex II site.   The  maximum annual  average concentration recorded at
 any of  the eight stations was 29 ug/m3,  which is about  50  percent of
 the Florida  annual  S02 AAQS  of 60 ug/m3.   Annual averages  for most
 years are less than 20 ug/m3,  reflective of  rural  air quality
 conditions.

 3.1.5.3   FLUORIDES
Ambient fluoride data  from the CF site  are presented  in Table 3.1.5-3.
Annual  average concentrations range from 0.3 ug/m3 to 1.6 ug/m3,
with  most averages  being  less than 1.0 ug/m3.   No  AAQS  exist  for F in
the State of  Florida.

                                3.2   NOISE
3.2.1  SOUND MEASUREMENT
The human ear perceives sound  between frequencies of 16 and 20,000
Hertz.  One important characteristic  of  the  human ear is that  throughout
its range of perception,  sounds of  equal  pressure level at different
frequencies are not perceived  equally.   Sounds  of low and high
frequencies are not heard  as easily as  sounds in the mid-range.   A
commonly used weighting scale,  which  nearly  approximates the response of
the human 4ar,  is  the A scale.   A sound  level meter measures the A scale
by electronically  attenuating  low and high frequency sounds.

The unit of measure in acoustics is the  decibel (dB), defined  as:
                 dB = 10  log PA2/PR2
     where PA is the measured  sound pressure level, and
           PR is a reference level  (in  this  case, 20 micropascals).

Guidelines for environmental noise  are defined  in terms of the A scale
and are expressed  as one  of the following  statistical measures (EPA,
1974).
     1.  LIQ—the  sound level  which is  exceeded 10 percent of  the
         time during a measurement  period.
     2.  1,50—the  sound level  which is  exceeded 50 percent of  the
         time during a measurement  period.
     3.  Le_(24)—the sound level equal  in cumulative energy to  all
         time-varying noise produced  during  a 24-hour period.
     4.  L
-------
EPA  (1974)  also  presents  Che following information on the nighttime
weighting  factor:

     The choice  of  the  10  dB nighttime weighting in the computation of
     Ljn has  the  following effect:   In low noise level environments
     below  Ljn of approximately 55  dB, the natural drop in Ljn values
     is approximately 10 dB,  so that  daytime and nighttime levels
     contribute  about equally to L^.   However,  in high noise
     environments,  the  night  noise  levels  drop relatively little from
     their  daytime  values.   In these  environments, the nighttime
     weighting applies  pressure towards around-the-clock reduction in
     noise  levels if the noise criteria are to be met.
3.2.2  REGULATORY GUIDELINES
EPA has published noise  levels  requisite  to protect  the public  against
hearing loss or activity  interference  for  various  land  use  categories
(EPA, 1974) (see Table 3.2.2-1).   Sound  levels are given as Leq<24)

 3.2.3  EXISTING NOISE ENVIRONMENT
 3.2.3.1  EXISTING ENVIRONMENT
 Hardee County is predominatly rural and depends upon agriculture as  its
 economic  mainstay.   Table 3.2.3-1 provides information on land use in
 Hardee County.   The proposed site, the Hardee Phosphate Complex II,  has
 primarily open  rangeland, improved pasture, and forest land uses.
 Property  surrounding the site is rural agricultural and is very sparsely
 populated.   The  nearest  muncipality to the site is Wauchula, the county
 seat,  about  2 miles away.  No major noise sources are currently located
 within the site  or  in the near vicinity.  The property is traversed  by
 the Seaboard Coast  Line  (SCL) Railroad, and bounded on the north by
 SR 62.  U.S. Highway 17  is located roughly 2.5 miles east of the site.
 These  transportation facilities are currently the most significant
 anthropogenic noise sources  in proximity to the site.   Figure 3.2-1
 illustrates  transportation facilities in Hardee County.

 Table  3.2.3-2 and Figure 3.2-2 describe characteristic sound levels  for
 various land use types.   From these sources,  monitoring  information  from
 similar locations,  and previous phosphate EIS's, ambient  Ldn noise
 levels  at  the CF site can be  expected to be between 40 and 50 dBA.
 Higher  levels could be experienced during periods of heavy traffic on
 SR 62,  when  the  SCL railroad  passes,  and during periods  of increased
 wildlife  activity.

3.2.3.2   PROJECTED  ENVIRONMENT WITHOUT THE PROPOSED PROJECT
The projected noise  levels at  the CF  site  can  be expected  to increase
 slightly  without the  proposed  project due  to  increased vehicular and
 rail activity stimulated  by  future  phosphate mining operations  a few
miles  south of the  site  in Central  Hardee  County.   The major population
growth corridor  in  Hardee County lies  along U.S.  17 between  Bowling
Green  and Zolfo Springs  and may contribute to  somewhat higher  on-site
noise  levels from increased anthropogenic  activity (e.g.,  additional
traffic on U.S.   17  and SR 62).

                      4.0   GEOTECHNICAL RESOURCES
                     4.1   THE AFFECTED ENVIRONMENT
4.1.1  REGIONAL DESCRIPTION
4.1.1.1  GEOMORPHOLOGY
The project  site  is  located in northwestern Hardee County,  Florida,
within the Polk Upland  region of  the  mid-peninsula physiographic zone as
described by White (1970)  (see Figure 4.1-1).   The Polk Upland is a
broad, slightly dissected,  marine terrace,  ranging in elevation from 100
to 150 feet  above mean  sea level  (msl).  It is bordered on  the north by
the Western  Valley and  the Lake Upland, and on the east by  the Lake
Wales Ridge.  Several miles south of  the site  the terrain is the gently
sloping, nearly undissected DeSoto Plain ranging in elevation from 30 to
100 feet msl.  To the west lies the Gulf Coastal Lowlands.

Except for the Winter Haven,  Lakeland,  and  Lake Henry ridges which rise
from its surface  in  the northeastern  part,  the Polk Upland  is a broad
area of low  topographic relief.   Both the uplands and the lowlands
appear to have been  eroded to their present elevations from a paleo-
highland.

4.1.1.2  SOLUTION FEATURES
The occurrence of solution features varies  throughout the region and is
restricted by the thickness  of overburden over solution-prone limestones
and the depth of  the potentiometric surface.   The thick layer of
solution-resistant clastic  sediments  (White, 1970) above the Hawthorn
formation and the occurrence of a near-surface water table  in the region
of the mine  site combine to  reduce the  potential for sinkhole
development.

4.1.1.3  STRATIGRAPHY
The basement rocks in Florida consist of both  crystallines  and
sediments.   The crystalline  rocks range from granites to basalt flows
and pyroclastics, while the  sediments are primarily unmetamorphosed to
very weakly  metamorphosed  noncalcareous shales and sandstones (Applin
                             4-1

and Applin, 1944).  The basement rocks are pre-Cretaceous  in  age
(Figure 4.1-2).  They are overlain by  a wedge  of  Cretaceous and Cenozoic
sediments.  This wedge thickens from about 4,300  feet  in southeastern
Georgia to nearly 12,000 feet  in Southern Peninsula  Florida.

Throughout Florida the Cretaceous and  overlying Cenozoic section
consists primarily of shallow-water marine carbonates  and  evaporites,
claystones and partially cemented to uncemented sands,  silts,  and  clays.
Cenozoic strata are the only units which were  encountered  during
previous investigations conducted on the property.

4.1.1.4  STRUCTURAL GEOLOGY
Regional structural features that have influenced the  geology at  the
project area are the South Florida Basin, the  Kissimmee Faulted Flexure,
and the Ocala Uplift (Figure 4.1-3).   The South Florida Basin is  a
downwarp structure that plunges westward toward the  Gulf of Mexico with
its axis trending east-west.   Sediments within the basin are  Mesozoic
and Cenozoic in age and have a gentle  dip to the  southwest.   The basin
subsided slowly from Jurassic  to Middle Eocene.   During this  time, the
environment of the basin was essentially that  of  a shallow to deep shelf
supporting carbonate and evaporitic cyclic deposition.  The Kissimmee
Faulted Flexure is a local, fault-bounded tilted  and rotated  block of
Eocene or Oligocene age extending down the Florida Peninsula  in Orange,
Osceola, and Lake Counties.  The regional structural feature  that  has
the most significant effect on the project site is the Ocala  Uplift,  a
gentle, local anticlinal structure.

The Ocala Uplift centers around outcrops of  the Ocala  Group (Upper
Eocene) and Avon Park Limestone (Late  Middle Eocene) in Citrus, Dixie,
and Levy Counties on the West  Coast of the peninsula.   Where  exposed,
the uplift is about 230 miles  long and 20 miles wide.   Fracturing  and
faulting of the Tertiary rocks is associated with the  development  of  the
uplift (Vernon, 1951).

4.1.1.5  SEISMICITY
Very low seismic  activity  has  historically characterized the State of
Florida.  In modern  times  few  significant  events  which occurred  within
the state have been  recorded.   Stover e_£ al^.  (1979)  reported that  the
maximum intensity of events  known to  have  occurred within the state was
recorded at Modified Mercalli  (mm) intensity  V.   There is little chance
that events of stronger  intensity will be  observed  in Florida.

4.1.2  SITE-SPECIFIC DESCRIPTION—GEOLOGY
The geologic formations  penetrated during  the drilling phase of  previous
on-site investigations range in age from Eocene  to  Recent.   In ascending
order, the formations encountered are:  the Lake  City Limestone, Avon
Park Limestone and Ocala Group of Eocene age; the Suwannee  Limestone of
Oligocene age; the Tampa and Hawthorn Formations  of  Miocene age; and
undifferentiated clastic deposits ranging  in  age  from Pliocene to
Recent.

In the following sections, regional and site  characteristics of  the
individual geologic formations  have been taken from  the CF  DRI
descriptions.  A general Stratigraphic Section is shown for the  site
area in Figure 4.1-4.  A literature review and an evaluation of  both the
geologic and geophysical logs  from four on-site  wells (ranging from 948
to 1,702 feet deep) were used  to delineate the formations.

4.1.2.1  EOCENE SERIES
Lake City Limestone
The Lake City Limestone  has  been described in nearby Polk County
(Stewart, 1966) as a white to  cream,  moderately  soft to hard chalky
limestone with scattered chert nodules in the upper  part of the
formation.  Anhydrite, gypsum,  and selenite occur as nodules throughout
the formation.  The  continuity of lithic material from the  Lake  City
Limestone into the overlying Avon Park Limestone  suggests that the
contact is transitional.  Average thickness of the Lake City Limestone
in Polk County is 419  feet.

At the CF  Industries  site  in  northwestern Hardee  County,  the  Lake  City
Limestone  consists  of medium  brown to  very light  brown, moderately soft
to indurated  fossiliferous  limestone.   Dolomite also is present
scattered  throughout  the upper  part of the formation.   The  contact
between the Lake City Limestone  and the overlying Avon Park Limestone  at
a depth of about 1,590 feet was  based  on the occurrence of  abundant
nodules of evaporite  minerals at that  depth.  Thickness of  the  Lake  City
Limestone  at  the project site is a minimum of 110 feet.

Avon Park Limestone
In Polk County, the Avon Park Limestone is a dark brown to  cream,  very
hard to soft, granular to chalky to finely crystalline, highly
fossiliferous limestone (Stewart,  1966).  Within  the limestone  section
there is normally a dolomite  zone  ranging from 80 to 135  feet thick
which occurs  from 57  to 220 feet below the top of the  formation.   Wilson
(1975) provides a similar lithic description for  the Avon Park  Limestone
in Hardee and DeSoto  Counties and  gives thicknesses ranging from 200 to
470 feet for the entire formation  and  a minimum of 150 feet for  the
dolomite zone.

In northwestern Hardee County at the project site, the entire thickness
of the Avon Park Limestone  was  penetrated by the  Deep  Floridan  Test
Well.  The formation  consists of three lithic types.  The upper unit is
a very light brown, very fine grained  to coarse grained,  dense
crystalline to coarse grained bioclastic limestone approximately 90  feet
thick between depths  of 940 to  1,030 feet below ground surface.   The
middle unit is a dark yellowish brown to light yellowish  brown,  fine to
medium grained, crystalline and  highly indurated  dolomite approximately
230 feet thick between depths of 1,030 and 1,260  feet  below ground
level.  Within the  dolomite unit at depths between 1,130  and  1,160 is  a
dark, granular, gravel-like dolomite "rubble" zone.  This zone, also
described  by  Stewart  (1966) in  Polk County, contains abundant solution
features and  fractures commonly lined by coarse  to fine well-developed
crystals.  The basal  unit  of  the Avon Park Limestone is dominantIy
limestone  and very  similar to the underlying Lake City Limestone except
                             4-8

-------
for an absence of evaporite material.  Total  thickness  of  the  Avon Park
Limestone at the project site  is  about 650  feet.

Ocala Group
In Polk County, the Ocala Group as described  by  Stewart (1966) includes
three formations.  In ascending order these are:   (1)  the  Inglis
formation; (2) the Williston formation,  and (3)  the  Crystal  River
formation.

The Inglis formation in Polk County  is a white to  cream to dark brown,
generally hard to very hard, granular, partially to  highly doloraitized,
highly fossiliferous limestone with  local soft chalky  zones.   This
member is 75 feet thick in parts  of  Polk County  (Stewart,  1966).   At  the
CF Industries site in northwestern Hardee County,  the  lithology of the
Inglis formation is similar to that  described by Stewart in  Polk  County.
The Inglis unconformably overlies the Avon Park  Limestone  and  is  present
between depths of 830 and 940  feet below ground  surface.   Total thick-
ness of the Inglis is about 110 feet.

Overlying the Inglis formation in Polk and Hardee  Counties is  the
Williston formation which consists of white to cream to brown, generally
soft, coarse limestone with coquina  of foraminifera  set in a chalky,
calcite matrix (Stewart, 1966).  The lower 5  to  15 feet are  usually
harder than the rest of the member due to dolomitization.  Thickness  of
the Williston in Polk County ranges  from 10 to 100 feet and  averages
about 30 feet.  At the CF Industries site in  Hardee  County,  the
Williston formation was observed between depths  of 770  to  830  feet for  a
thickness of about 60 feet.

The Crystal River formation as described by Stewart  (1966) and as
observed at the project site in Hardee County is a white to  tan,  medium
grained to chalky limestone with  large foraminifera  common.  The  thick-
ness in the project area is about 95 feet between  depths of  675 and
770 feet below ground surface.
                               4-9

4.1.2.2   OLIGOCENE  SERIES
Suwannee  Limestone
In nearby Polk  County,  the  Suwannee Limestone which overlies the Ocala
Group  is  a white  to  cream or  tan,  generally very soft, granular,
detrital  limestone  which  is generally very pure.  It contains abundant
bryozoa,  small  mollusks and large  echinoids (Stewart, 1966).

In northwestern Hardee County,  the Suwannee Limestone is a white to very
light  brown limestone with  fine  to coarse grained carbonate grains in a
carbonate matrix.  Echinoid fragments are common.  Wilson (1975) states
that the  contact  between the  Suwannee Limestone and the overlying Tampa
Limestone can often  be identified  on gamma logs by the marked decrease
of gamma-ray intensity in the Suwannee Limestone.  This was observed on
gamma  logs from the  Deep Floridan  Test Hole at about 467 feet below
ground surface.   The thickness of  the Suwannee Limestone at the project
site is,  therefore,  about 208 feet.

4.1.2.3  MIOCENE  SERIES
Tampa Formation
Stewart (1966)  describes the  Tampa formation in Polk County as a
calcareous clay with occasional  beds of white to gray sandy limestone.
Wilson (1975) uses the name Tampa  Limestone and describes an upper
limestone which he does not differentiate from limestone in the
overlying Hawthorn formation  and a lower sand and clay unit.

In the Deep Floridan Test Well at  the CF Industries project site,  the
Tampa  formation was  observed  between depths of 370 and 467 feet below
ground surface.   The formation consists of two units.  These are an
upper  limestone unit and a  lower sand and clay unit.  The upper contact
with the  Hawthorn formation is determined on the basis of a distinct
lithic change from a sandy, clayey, phosphatic limestone of the
Hawthorn  formation to a irelatively pure, slightly sandy and slightly
phosphatic, fossiliferous limestone of the Tampa formation.  This
contact was observed in drill cutting and on gamma logs and occurs at
about 370 feet  below ground surface.  The thickness of the limestone
                              4-10

-------
 unit  is  61  feet  at  the Deep Floridan Test Well.  The lower unit of the
 Tampa formation  is  a dark greenish gray sandy clay.  The upper few feet
 of the clay are  silicified.  The top of the lower unit is placed at
 431 feet below ground surface which indicates a thickness of 36 feet for
 the sand and clay and a total of 97 feet for the Tampa formation at the
 project  site.

 Hawthorn Formation
 Overlying the Tampa formation is the Hawthorn formation which has been
 described by Stewart (1966) in Polk County as consisting of interbedded
 sandy limestones and sandy clays which are not individually distinctive.
 The clays are soft, sandy, phosphatic and usually a gray to dark bluish
 or greenish gray.  The limestone beds are light cream to yellow or tan,
t
 very hard to soft,  very sandy, clayey and phosphatic.

 In the Deep Floridan Test Well, the Hawthorn formation was observed
 between  depths of 43 to 370 feet below ground surface.  The formation
 consisted of yellowish gray grading to medium gray to very light gray,
 fine gained, indurated to very soft, pure to abundantly phosphatic and
 sandy limestone. The clay content increased with depth becoming very
 clayey  in the lower portion.  Chert also occurs scattered through the
 lower portion.

 4,1.2.4   PLIOCENE TO RECENT - UNDIFFERENTIATED CLASTICS
 Wilson  (1975) divides the material above the Hawthorn limestone into
 three units:  a  phosphatic unit, a shell and sand unit, and an upper
 sand unit.   The  combined thickness of these average 40 feet in DeSoto
 and Hardee  Counties.

 At the CF Industries site  in northwestern Hardee County, the combined
 thickness of the undifferentiated 'elastics is variable as is the
 thickness or presence of the individual units.  In the Deep Floridan
 Test Well,  43 feet  of light gray to yellowish gray, phosphatic sandy
 clay was observed overlying the Hawthorn limestone.  The average
                               4-11

-------
 thickness over the project area  is  approximately  32  feet.  The results
 of exploratory drilling on the property  have  been summarized by  CF  in
 Figure A.1-5 which shows the thickness between  the base of the ore  zone
 and the top of the limestone.

 Because of the extensive geologic information available from previous
 studies, on-site geologic investigations for the  EIS were limited to a
 series of six shallow core borings  (approximately 50 feet deep) drilled
 in the study area.  As shown in Figure 4.1-6, a general geologic cross
 section of the upper undifferentiated elastics  on Complex II was
 developed  from these borings.

 4.1.3   SITE-SPECIFIC DESCRIPTION—SOILS
 A  detailed description of the soils on the CF property was developed in
 the Application  for  Mineral  Extraction (1976) and the CF DRI (1976).
 The following  section has been taken from these sources and discusses
 the entire CF  property,  and  does  not differentiate between Complex I
 (the existing mine)  and  Complex II (the study area).   The  maps  included
 also show both Complex I and  Complex II undisturbed,  even  though
 Complex  I is presently an active  mining area.

 The site area  is  characterized  by low topographic relief,  localized
 depressional marshes,  and frequent  occurrence  of swamps.   Along the  more
 developed streambeds,  slopes  increase to 4  and 5 percent.

 The surficial soils  (the  top  60 to  80 inches)  can  be  divided  into three
 basic  groups which correspond closely to  vegetative types  and  landforms.
 These  are:  soils  formed on the broad upland  flats; soils  near  and
 around the marshes and swamps;  and  those  formed  in the  marshes  and
 swamps.

The high amount of rainfall in  the  site  area causes intensive leaching
of the surficial soils.  As a result,  the soils  are generally acidic  and
often contain layers  of organic matter and  clay  which have  translocated

downward into the soil profile.  This  intensive  leaching  creates
nutrient deficient soils that must be  fertilized prior  to utilization
for agricultural purposes.  A soils series map of the CF  site  is
provided in Figure 4.1-7.  Characteristics of each unit  are  summarized
in Table 4.1.3-1.  For more information  on soils in general  see Brady
(1974); for descriptions of soils  of  this  area  see Leighty and others
(1958), Furman (1975), and Caldwell and  others  (1958),  and SCS Interim
Soil Survey for Hardee County (1979).

4.1.3.1  METHODS OF  INVESTIGATION
The southern portion of  the site west  of the rail line  (Figure 4.1-7)
was surveyed by the  United States  Department of Agriculture  Soil
Conservation Service as  part of a  conservation  farm plan developed for
the Stuart Brothers,  former owners of  the  land.   Most of the remaining
site areas were surveyed by qualified  soils  scientists.  However, one
small  area that was  not  planned for mining was  not surveyed  because of
inaccessibility.   Soil-landscape-vegetation  relationships and
associations on previously surveyed  areas  were  used as  a basis for
differentiating soils in previously  unmapped areas.  This study was
supplemented by field reconnaissance.   Hand  auger samples were used to
verify areas of uncertain  soils composition.  Since the on-site soils
investigations were  conducted  in 1976, the SCS  has published an Interim
Soil Survey  for Hardee County.   This 1979 survey was used to update soil
series for two of  the soils  found  on the CF  site (i.e., Pamlico muck and
swamp  were updated to Tomoka muck and Delray mucky  fine sand
depressional, respectively).

4.1.3.2  DESCRIPTION OF SOILS
Predominant  soils  on the property are the Myakka  fine sand and the
Myakka fine  sand-thin surface.   In general,  these  soils underlie  the
 flat,  broad  upland areas called flatwoods.  Other  soils  commonly
 associated with  upland areas  are the Immokalee, Wabasso,  and Wauchula.
All  of these soils are highly leached, moderately  wet, and  strongly
 acid.   They  have  a thin surface horizon underlain  by a bleached horizon.
 At depths from 15 to 40 inches, a layer of  accumulated organic matter

 and mixed iron and  aluminum materials is present.   Agricultural
 productivity of  the  flatwoods  soils  is  limited by  wetness.   These soils
 are not suitable  for cultivation  unless  some kind  of water  control  is
 practiced.  Even  then,  the  potential  productivity  of vegetables or
 improved pasture  is medium  and  the potential productivity of citrus  is
 low.  The potential productivity  of pine plantations is  moderately  high
 when water control practices are  used.   These soils  cover approximately
 62 percent of the CF property.

 Soils found  primarily in the flat uplands  surrounding  the marshes and
 swampy areas are  estimated  to cover approximately  5  percent  of  the
 property and include the Felda, Manatee, Ona, Parkwood,  and  Pompano
 soils.   Soils  in  this group are neutral  to slightly  acid  and are  some-
 what less  leached than  those found in the  flatwoods  areas.   They  lack an
 organic  pan  within the  profile but are often  underlain by calcareous
 clayey materials.   Productivity of the soils  found on  the flat  uplands
 surrounding  the marshes  is similar to the potential  productivity  of the
 flatwoods  soils.

 Soils  formed in marshes  and  swampy areas comprise approximately
 33  percent of the  property.   The marshes are grassy  depressions which
 are  covered with  water during the wet  season.  During the dry season,
 the  water  table in the marsh areas lowers to the soil surface,  or is
 just below it.  Marsh soils  comprise  20  percent of the property,  and  are
 dominated by the  Basinger,  ponded Felda,  Placid, and Pompano series.
 The  swampy areas  which are covered with  water throughout most of  the
 year, comprise 13  percent  of the property.  They are hummocky,  covered
 with oak vegetation,  and are represented  by Bradenton, Toraoka muck
 (prior to 1979, name was Pamlico Muck),  and Delray (prior to 1979, name
was  swampy soils)  mucky  fine sand  soils.   These soils are generally dark
colored, often calcareous  at the surface, and in low areas have an
organic layer varying in thickness from 2 to  30 inches.
                                     4-18

-------
Productivity of the soils in the marsh and  swamp  areas  depends  on  the
length of time the soils remain under water  and/or  the  ability  to  drain
the soils.  The soils that are flooded by nearby  streams  are  unsuitable
for citrus or cultivated crops unless the  flood waters  can  be
controlled.  These soils do, however, have  a hi?h potential  for pine
plantations.  The soils that are flooded by a  rising  water  table are not
suitable for pine plantations and sometimes  are not suited  to growing
cultivated crops.  The soils in the depressions are difficult to drain
because of the lack of suitable outlets  for  water flow.  These  soils
have a high potential for range because  the  periodic  high water
naturally restricts grazing, increasing  productivity.

Dust Potential of the Soils
The dust potential of the soils is dependent on a number  of factors.
These include parti-cle size and organic matter content, soil  moisture
levels, extent of vegetative cover, soil surface  condition  (smooth
versus rough), and wind velocity and  turbulence.  Table 4.1.3-1 gives
the rating for dust potential of each soil  series of  the  CF property.
These ratings show that erosion potential  is moderate  to  low for all
soils except Pamlico muck.

Evidence of severe wind erosion such  as  sand build-up along fence  rows
and windbreaks and accumulation in ditches  was not  observed in  signifi-
cant quantities on the site.  Low dust potential  is charactistic of most
of the site soils due to the low organic matter,  clay,  and  silt content.
However, dust and wind erosion may result  when some soils on the site
are dry and exposed for some time.  Soils  susceptible  to  erosion under
these conditions are those with high  levels of organic  matter and  a deep
surface horizon.  Pamlico muck, if exposed  and dry, is  the  only soil on
the site with high dust potential.  Manatee, Myakka,  Ona, and Placid
soils have moderate to low dust potential  when exposed  and  dry.  These
last soils all have dark colored surface horizons at  least  6 inches
thick.  It should be emphasized that  these  soils  blow only  if dry and
exposed.
                                    4-19

-------
 Erosion Potential  of the Soils
 In the undisturbed  state,  soils  on the site have a Low erosion potential
 (Table 4.1.3-1) due to  the flat  topography, the sandy nature of the
 soils, and the presence  of good  vegetative cover.

 The entire CF site  is characterized  by low topographic relief.  This
 inhibits rill or gully erosion because of  relatively  slow water movement
 from the area.

 Soil structure is important in reducing erosion, but  not  necessarily in
 all cases.   Soils of the property  are  characterized by high  rates  of
 infiltration  due  to their  sandy  texture.   This  increased  infiltration
 reduces  run-off considerably.  The coarser soil  particles  typical  of the
 CF site  will  not  become  suspended readily  and will be  transported  for
 much  shorter  distances than clay or silt particles.

 Depth  to Bedrock
 Borings  indicate  that the Hawthorn formation (Bedrock)  is  overlain  by an
 average of  10 to  50 feet  of recent undifferentiated elastics.   Bedrock
 is defined  as the  solid  rock that underlies the soil and other
 consolidated  material.

 Permeability
 Permeability  is a measure of the  rate at which water will  pass  through
 soil under  saturated conditions.   Typical  permeabilities for soils  found
 at the site (Table  A.1.3-1) range from 0.6 to 20 inches per hour for the
 entire surface profile.   The Florida Agricultural Experiment Station has
 measured the  permeability for  specific soil layers.  These data,
 expressed as  hydraulic conductivity (Table 4.1.3-2) range  from 0.03  to
 20 inches per hour.   The  lower permeabilities are the result of a higher
 fraction of silt and clay sized particles.

 Presumptive Bearing  Value
For sandy soils such as those  found on the  site,  natural bearing values
are high when soils  are dry (over 2,000 psf),  and become low when soils

* These values were measured by the Florida Agricultural Experiment
  Station for soil types found on the site.  These are the laboratory
  results of field samples analyzed at saturated  test conditions.
  Undisturbed soil was sampled directly  in the  field  in southern Florida
  on identified soil types and tested in  the laboratory.  The results
  represent the rate at which water will  flow through soil layers under
  saturated conditions.  Uniform soil layers, or  horizons were
  identified and tested rather than arbitrarily testing at selected
  depths.

are saturated  (less  than 2,000 psf) (Table 4.1.3-1).  These soils are
suitable  for roads,  low buildings, and other foundations if adequately
drained.

The presumptive bearing value  does not consider engineering preparation
of the in situ soils  or the  type  of foundations to be constructed.
Bearing values for prepared  foundations in upland areas can be expected
to be greater than 2,000  psf for  most  footings.  The bearing value of
the soils in marshy and  swampy areas  is very low.  Soils with high
organic content will  be  removed and replaced with suitable soils prior
to construction.

                      5.1  THE AFFECTED ENVIRONMENT
 5.1.1   REGIONAL DESCRIPTION
 Man has been subjected to radiation from naturally occurring
 radionuclides throughout his existence on earth.  The primary nuclides
 contributing to this background dose level on a worldwide  basis  are
 potassium-40 and nuclides of the uranium-238 and thorium-232 decay
 chains (EPA, 1972).  These nuclides are contained in varying
 concentrations in the earth's crust and in surface and ground waters.
 In  Florida,  the nuclides of the uranium-238 series are the primary
 source of  natural radiation.

 The phosphate deposits of Florida contain concentrations of uranium, and
 its decay  products, at levels approximately 30 to 60 times greater than
 those  found  in average soil and rock throughout the rest of the United
 States.  Uranium is found both  in the  phosphate matrix and in the
 overburden in the region, although concentrations in the matrix are
 higher and more  uniform.   The natural  radiation levels experienced at
 the surface  due  to  radioactive  materials  in the phosphate matrix vary
 with variations  in  matrix depth and  in overburden composition.

 The  act of mining and  processing phosphate  changes the physical form,
 location,  and  concentration of  naturally  occurring radioactive
 materials.   Phosphate  mining operations have  the potential to increase
 direct human  exposure  to  naturally occurring  radioactivity.  The mining,
 transportation,  and processing  of the  phosphate matrix and overburden
 can  increase  exposure  by  releasing some of  these naturally occurring
 radioactive materials  as  gases,  airborne  particulates,  or waterborne
 effluents.

The Areawide EIS  (EPA,  1978)  presented  a  detailed  discussion  of
 radioactivity  in  the central  Florida phosphate  area,  and  its  potential
                            5-1

-------
 environmental effects.   The  conclusion of that study was that  the radio-
 active isotopes of  environmental  importance in the study area  are those
 in the uranium-238  decay  series.   This  conclusion  is based  upon  their
 abundance in the matrix  and  soils,  their  potential for transport, and
 their potential for accumulation  in  human tissue.   A detailed  discussion
 of the distribution and effects of  these  isotopes  is presented  in the
 following sections.

 5.1.1.1   URANIUM,  RAD101SOTOPES AND  EXPOSURE
 Uranium  has  two  naturally occurring  isotopes,  uranium-238 and  uranium-
 235.   The uranium-238 series has  a  longer half-life  and  accounts  for
 99.28  percent  of the naturally occurring  uranium.  Almost all naturally
 occurring radiation in the phosphate deposits  is associated with  uranium
 and  its decay  products.   Although thorium-232  represents the parent
 radionuclide of  another  naturally occurring series,  the  concentration of
 thorium  in Florida  formations is very small compared  to  uranium.

 Specific  data  on thorium-232 in Florida phosphate-associated media are
 found  in  an EPA  technical note (EPA, 1975) and in direct correspondence
 with  several phosphate companies after EPA reconnaissance trips in 1974
 (Windham,  1974).  These  data indicate the uranium/thorium ratio (in
 terms  of  pCi/g)  to  be  about  90 for marketable  rock, 30 for clays  and  60
 for  air particulate  samples.   Any  single ratio may have considerable
 error  since the  low values for observed thorium concentrations had high
 associated errors (+30 percent).   Guimond (1977) shows that thorium-232
 radioactivity  concentrations  in marketable phosphate rock from the study
 area are  two orders  of magnitude  less than those of natural uranium.
 Habashi (1966),  in  using  scintillation spectrometry to study
 radioactivity  in phosphate rock,  detected  no peaks  due to thorium or   its
decay  products in phosphate  rock  samples from Florida, indicating the
virtual absence of  this  particular radionuclide in  the samples  studied.
 It is evident that,  on an activity basis,  thorium contents  in the
Florida phosphate areas are nearly two  orders  of magnitude  lower
                           5-2

than the world average.  Thorium  is,  therefore,  not  discussed  further in
this report.

In the uraniura-238 decay series,  decay  proceeds  from U-238,  through 13
intermediate daughter radionuclides until  the  stable nuclide,  Pb-206, is
reached.  This decay series  and the associated half-lives  are  shown in
Figure 5.1-1.  If the entire series is  contained in  a sealed
environment, a state of equilibrium is  reached for  the entire  series.
In undisturbed phosphate deposits, such an equilibrium exists  at  least
for the radionuclides through  radium-226.   This  equilibrium  is
maintained only if the materials  are  undisturbed.  Mining  and  processing
represent significant disturbances to this equilibrium.

The radionuclides in the uranium  decay  series  which  are  of greatest
importance to human exposure are  radium-226,  its decay product radon-
222, and the radon daughters polonium-218,  lead-214,  bismuth-214,  and
polonium-214.  These six radionuclides  are responsible for the majority
of human exposure to radioactivity in phosphate  mining and processing.

Radium-226 is of particular  interest  with  respect  to human exposure,  as
it is chemically similar to  calcium and tends  to be  incorporated  in the
same way as calcium in bone  and other biological material.  Radium's
chemical similarity to calcium is also  demonstrated  by its tendency to
replace calcium in primary phosphatic apatite.   Radium-226 has a
relatively long half-life (1,620  years)  and may  enter the  body through
contaminated drinking water  or by breathing suspended particulates
contaminated with radium.  EPA (1975) limits  the total radium
concentration (Ra-226 plus Ra-228) in drinking water to  less than
5.0 pCi/1.

Radium-226 decays to radon-222, an inert gas.  The decay equilibrium
from Ra-226 to Rn-222 is largely  dependent upon  the  mobility of gas out
of the soil and into the atmosphere.  In natural undisturbed conditions,
most Rn-222 does not escape  the matrix  strata.

 Rn-222 and  its daughters  are of  special  concern  because  of  the  potential
 mobility of Rn-222 (as a  gas)  from  the environmental media.   Once  in the
 atmosphere, radon-222 can be inhaled and thus can  increase  the  exposure
 to lung tissue.  Although not  gaseous, the  radon daughters  enter the
 body primarily throughout the  inhalation of  respirable particles formed
 in the decay of gaseous,  airborne radon-222.  These radon daughters
 therefore increase the exposure  to  lung  tissue.

 The radionuclides U-238, U-234,  Th-230,  Ra-226,  and Po-210  are  all  long-
 lived radionuclides that could become airborne in  dusty  operations or  by
 other mechanisms.  If not controlled, these  radionuclides have  the
 potential to be health hazards.

 5.1.1.2  RADIOISOTOPES AND PHOSPHATE DEPOSITS
 Previous studies (EPA, 1978) have indicated  that the uranium  present in
 central Florida phosphate may  have  been  deposited  along  with  the primary
 deposits of the phosphate mineral apatite during the Middle Miocene
 epoch.  During subsequent reworking of these primary deposits,  the
 phosphate was concentrated into  the secondary phosphate  deposits now
 found in central Florida.  The physical  and  chemical processes  associ-
 ated with the reworking of the primary phosphate deposits resulted  in
 the concentration of both phosphate and  uranium.  The  secondary phos-
 phate deposits of central Florida typically  exhibit average uranium
 concentrations of 0.01 to 0.02 percent (100  to 200 ppm).  In  contrast,
commercial  mining of uranium generally exploits  ores with uranium
concentrations 10 to 20 times higher (0.1 to 0.4 percent).  Most other
minerals in the phosphatic matrix have maximum concentrations of only  a
 few parts per billion (EPA, 1978).

 The structure and uranium content of a typical cross section  in the
 central Florida phosphate area is shown  in  Figure  5.1-2.  Representative
 radium-226 concentrations for various soils, phosphate materials,
 effluents, and ground waters are summarized  in Table 5.1.1-1.   Radio-
 activity levels are typically  at minimim levels  at the ground surface.

 and increase with depth.  Overburden soils are generally mixed  layers  of
 sands and clays exhibiting  low concentrations of radionuclides.

 The leach zone, also known  as  the  aluminum phosphate zone,  consists  of a
 discontinuous zone of  altered,  friable phosphatic sandstone and  is
 considered to be the upper  part  of the Bone Valley formation.   It  is the
 result of water movement  through a calcium phosphate zone,  converting  it
 to aluminum phosphate.  As  a result,  the  leach zone contains radio-
 isotopes at levels comparable  to those which are observed within the
 calcium phosphate matrix  zone  (the  lower  Bone Valley formation).
 Locally, radioisotope  levels in  the leach zone may be either higher  or
 lower than the underlying matrix.   As  the aluminum is considered  to  be
 an undesirable contaminant  in  the  phosphate rock product, the leach  zone
 is usually not mined,  in  which case  it  is removed  as  overburden
 material.  However, there are  some  instances  in which the leach  zone
 will  be  mined along with  the matrix.

 The matrix zone (the calcium phosphate  zone)  consists of apatite,
 raontraorillonite and other clays, quartz,  chert,  and  calcite, and is
 considered to be the lower part  of  the  Bone Valley formation. After
 mining,  the matrix  is subjected  to  the  beneficiation  process to separate
 the phosphate rock  product,  the  clay and  the  sand.  Most of the uranium
 and uranium daughter products emerge from the beneficiation process  in
 the phosphate rock  product and the discarded  clay-sized  fraction, with
 relatively little radioactive material  contained in  the sand tailings.
 This distribution results because the radionuclides  are contained
 primarily in  the phosphate deposits.  About two-thirds of the phosphate
 is  contained  in  the  rock product, and the remainder  is entrained in  the
 clay portion  (Guiraond,  1975).

in the underlying soils.  Florida readings  agree closely with  the
approximately 105 mR/yr. gamma level average  for the  U.S.  (EPA,  1972)  of
which about 45 mR/yr. is attributable to  cosmic  radiation,  and  the
remainder to terrestrial sources.  Both Florida  and U.S.  average  levels
yield doses which are well below the 500  millirems/year  (mrem/yr.)
limits for individuals in the general public,  and are more  than an  order
of magnitude below the limits for occupational exposure  (NCRP,  1975).

5.1.2  SITE-SPECIFIC DESCRIPTION
To characterize the radiation which exists  at  the CF  site,  numerous
site-specific studies were performed.  These  studies  included  sampling
and analysis of external gamma radiation,  surface materials, subsurface
materials, ground water, and surface water.  As  part  of  CF  DRI studies
and continued monitoring work, the external gamma radiation has been
measured on Complexes I and II from July  1976  through June  1982.  As
part of the EIS monitoring, surface materials  were sampled  and  analyzed
from six locations on Complex II in August  1981.  Subsurface materials
were composited over various depths at 6  bore  holes on Complex  II in
September 1981.  Ground water samples have been  collected  from  shallow
aquifer, secondary artesian aquifer, and  Floridan Aquifer wells on
Complexes I and II 11 times between February  1976 and September  1981.
Surface water samples were collected quarterly on Complex I from  January
1976 through March 1978 and monthly on Complexes I and II  from July 1981
through June 1982.  Four samples were also  collected  from mine  discharge
waters during EIS monitoring.  Each analysis  is  described  in further
detail in the following sections.

5.1.2.1  EXTERNAL GAMMA RADIATION
External gamma radiation has been measured  at  the CF  site using
thermoluminescent dosimeters (TLDs).  A total  of 16 TLDs are scattered
throughout the CF property, including 10  located in the  Hardee  Phosphate
Complex II study area.  Dosimeter locations are  shown in Figure 5.1-3.

In addition, one'TLD was located  in Wauchuia and  two  TLDs  were  used  as
controls and were not deployed  in  the  field.

Maximum external gamma radiation dosages encountered  on  the  CF  property
are summarized in Table 5.1.2-1 for the period  from third  quarter  1976,
through second quarter 1981.  For  the  EIS study period (third quarter
1981, through second quarter 1982), gamma radiation dosages  measured  at
all 17 TLD stations are summarized in  Table 5.1.2-2.

Effective January 1, 1986, CF modified  its environmental monitoring
program after generating a 10-year data base.   In  this revised  program,
external gamma radiation measurements  have been discontinued.

5.1.2.2  SURFACE MATERIALS
To characterize existing Ra-226 in surface soils  and  vegetation, one
soil sample and two pasture grass  samples were  collected at  six sites
distributed in the South Pasture.  Sample locations are  shown in
Figure 5.1-4.  These samples were  analyzed for  Ra-226.   In addition,
stream sediment samples were collected  at surface  water  quality stations
WQ-2, WQ-3, WQ-5,  WQ-8, and WQ-10.  These samples  were analyzed for
Ra-226.  The results of these analyses  are presented  in Table 5.1.2-3.
All materials collected were observed  to be extremely low  to low in
radium-226 content.

5.1.2.3  SUBSURFACE MATERIALS
To characterize the subsurface  background radiation at the site, a
series of six cores were drilled at representative locations over  the
undisturbed South Pasture Mine  site (see Figure 5.1-4).  These  locations
were selected in areas which have  typical subsurface  characteristics
(i.e., soil types, matrix types, and overburden thickness).

Three to five composite samples from each core  were collected from
various depths from the land surface to the matrix.   Typically,
composite sample fractions were collected from  the overburden,  leach
zone, upper matrix and lower matrix.   These samples were analyzed  for
radium-226.  The results of this sampling and analysis program  are
summarized in Table 5.1.2-4.

-------
In addition,  to  assist  in  characterization of the expected radiation
levels  after  reclamation,  a series of four cores, varying from 1  to
4.8 feet deep, were  collected  from reclamation materials or reclaimed
areas at the  existing North Mine.   Reclaimed materials sampled included
sand/clay mix, sand  tailings,  and  an overburden cap.   Cores were
observed to be relatively  homogeneous and, therefore,  only one composite
sample  from the entire  core depth  was collected.  These samples were
analyzed for  radium-226 and the  results are presented  in Table 5.1.2-4.

At all  six core sample  locations on Complex II, the upper portions  of
the overburden (typically  0 to 6 feet in depth) were observed  to  have
low «2 pCi/g) radium-226  concentrations.   Below that  depth, higher
radium-226 concentrations  were observed in the deeper  overburden
material.  Maximum radium-226  concentrations were typically observed in
the leach zone and in the  upper  portions of the matrix.  The observed
concentrations and depth of radium-226 generally agreed with other
profile data  collected  elsewhere in central Florida's  phosphate area.

In the reclaimed areas,  the observed radium-226 concentrations
corresponded  with the origin and type of material sampled.  The over-
burden cap was observed to have  the lowest and the sand/clay mix  to have
the highest concentration.

5.1.2.4  GROUND WATER
To characterize the  existing Ra-226 in the shallow aquifer, secondary
artesian aquifer, and Floridan Aquifer, samples were collected and
analyzed routinely starting in February 1976.  Samples were collected
from ten shallow aquifer wells during February 1976, and from  three
secondary artesian wells and five  Floridan Aquifer wells in May 1976.
Sampling and  analysis on seven shallow aquifer wells  (SA-1 through  SA-4,
SA-6, SA-8, and SA-17)  and three secondary artesian wells (UF-4,  UF-5,
UF-6) and five Floridan Aquifer wells (LF-4, LF-5, LF-6, PTW,  and DF)
was continued semi-annually through 1978 and was performed annually
(April) during 1979, 1980,  and 1981.
                              5-18

-------
As part of the EIS monitoring  program,  shallow aquifer well SA-17,
secondary artesian aquifer  well  UF4,  and  Floridan Aquifer well LF4 were
sampled in September  1981 and  analyzed  for Ra-226 and gross alpha.  The
results of this extensive ground water  sampling and analysis program are
summarized in Table 5.1.2-5.

Shallow aquifer Ra-226 concentrations were observed to be low (almost
always less than  1 pCi/1) with  some  spatial and substantial temporal
variation.  Waters of  the secondary  artesian aquifer were observed to
have the highest  Ra-226 of  the  three  aquifers.   While some spatial
variation was observed, the secondary artesian aquifer was less
temporally variable.   In general,  the Floridan Aquifer was observed to
be lower in Ra-226 as  compared  to  the secondary artesian aquifer;
however, on the western portion  of the  property,  there appears to  be
little difference in Ra-226  levels.   Specifically,  the results of  Ra-226
analyses at UF-4  and LF-4 show  little difference,  which indicates  a good
hydraulic connection between the secondary artesian and Floridan Aquifer
in this area of the site.

5.1.2.5  SURFACE  WATER
To characterize the Ra-226  in surface water environment of the CF  site,
various sampling  and analysis programs  have been  conducted.  Grab
samples were collected for  Ra-226  analysis at  surface water quality
stations WQ-1 through WQ-7  on a  quarterly basis during 1976 and 1977,
and semi-annually during 1978  (see Figure 5.1-4 for station locations).
The results of these studies are summarized in Table 5.1.2-6.

As part of the EIS monitoring, more  extensive  monitoring for Ra-226 and
gross alpha was conducted.   Samples  were  collected  during July through
September 1981 at surface water  quality stations  W}-1 through WQ-5 and
WQ-7 through WQ-12.  In addition,  stations WQ-13  and WQ-14 were sampled
during September  1981.  During October  1981 through June 1982, stations
WQ-1 through 5, 7, 8,  10, 13, and  14  were sampled.   In addition, samples
representative of existing  mine  discharge were collected during August,
September, and October 1981; February 1982; and April 1982.  All samples
were analyzed for Ra-226 and gross alpha.   The results of these analyses
are summarized in Tables 5.1.2-7 and  5,1.2-8.

 The FDER water quality standard  for  total  radium  (Ra-226  plus  Ra-228)  is
 5  pCi/1.  In evaluating the observed  Ra-226  levels  with  respect  to this
 standard, it is important to consider the  presence  {or  potential
 presence) of Ra-228.  Radium-228  is  first  decay daughter  in  the
 thoriu..i-232 decay series, and  is  not  associated with  the  previously
 discussed U-238 decay series.  Therefore,  in order  for Ra-228  to  be
 present in significant quantities, Th-232  must be present  in significant
 quantities.

 Ln general,  on an activity basis  (pCi/g to pCi/g),  the radioactivity of
 U-238  and Th-232  in many soils and rocks of  the world is  approximately a
 1:1  ratio.   However, Th-232  content of Florida phosphate  associated
 media  has  been  reported  by EPA (1975) and  Windham (1974).  These  data
 indicate that  uranium/thorium ratio,  on an activity basis  (pCi/g  to
 pCi/g),  is about  90  for  marketable rock and  30 for clays.  Based  upon
 these  data,  it  is  apparent that uranium content of the material of  the
 phosphate deposits may be  as  much as  100 times greater than the thorium
 content.

 Similarly, the  decay daughters  of U-238 and Th-232, Ra-226 and Ra-228,
 respectively, will  follow  the  same trends.  On an activity basis, Ra-226
 may  exceed Ra-228  by as much  as a factor of  100.   In other terms,  if
 Ra-226  were  observed at the 5  pCi/1 level   in the  site area, Ra-228  would
 be  present only at  approximately 0.05 pCi/1.   This is well below  the
 detection limit of  1 pCi/1 +_  20 percent for Ra-228 using the USGS
 analytical procedures (R-l142-76).

 Based  upon this analysis,  Ra-226 levels observed  in the surface water
 are compared directly with the  total  radium standard of 5 pCi/1.   All
 surface  water and mine discharge Ra-226 measurements were observed  to be
 less than 5  pCi/1.   All surface water and  mine discharge concentrations
 for gross alpha were observed  to be less than the  FDER water quality
standard of  15  pCi/1.

                     6.1  THE AFFECTED ENVIRONMENT
6.1.1  REGIONAL DESCRIPTION—QUANTITY
The lithologic units in the Hardee County area are  summarized  in
Table 6.1.1-1.  Although these units vary widely in their water-bearing
characteristics, they can be grouped into three major hydrogeologic
aquifers:
     1.  Shallow or water table aquifer,
     2.  The secondary artesian aquifer, and
     3.  The Floridan Aquifer.

In general, the shallow aquifer system is highly variable,  but  is
typically capable of yielding small quantities of water;  therefore  the
shallow aquifer system is utilized mostly for domestic  supplies or  other
low-volume uses.  The secondary artesian aquifer is locally capable  of
yielding relatively large quantities of water.  However,  the major  water
source in the Hardee County area is the Floridan Aquifer.   The  following
discussion of regional ground water hydrology focuses on  the Floridan
Aquifer.

The Floridan Aquifer is comprised of primarily tertiary limestones  and
dolomites.  Although limestone units vary widely in hydrogeologic
properties, typically they are capable of producing large quantities of
water.  Yields of 5,000 gallons per minute (gpm) are common.  However,
due to the presence of various lower permeability rocks and clays
separating the limestone units, yield and quality can vary  significantly
with depth and location.

Recharge to the Floridan Aquifer occurs from rainfall,  surface  water,  or
shallow aquifer waters in areas with one of three distinct  features:
     1.  Areas where no confining layer is present  and  where the  aquifer
         is at or near land surface, or
                                     6-1

      2.  Areas where the Hawthorn confining  layer  is breached by
          sinkholes, or
      3.  Areas where there is a significant  water  level gradient  from
          the shallow aquifer to the level of the Floridan Aquifer.

 The Floridan Aquifer discharges water in primarily three ways:
      1.  Discharge from wells,
      2.  Springs and seeps,and
      3.  Upward leakage in areas where the potentiometrie surface of the
          Floridan Aquifer is  higher than the shallow aquifer.

 The potentioraetric surface of the Floridan Aquifer varies seasonally
 depending upon  the rate at which it is being recharged and discharged.
 Water levels  in the Floridan  Aquifer usually reach their lowest near the
 end  of  April, the end of the  dry season.   The water levels generally
 rise from May through September  and then usually remain stable through
 October.  This  rise corresponds  with the  onset  of summer rains.   With
 the  cessation of  rainfall  in  October,  the Floridan Aquifer begins a
 sharp decline which ends in May.   The  timing and extent of these
 seasonal  fluctuations in water  levels  vary from year to year due to
 variations  in the rate  of  recharge  (due  to rainfall)  and in  pumping
 rates from  production wells.

 The  seasonal fluctuations  of  the  potentiometric  surface in a USGS well
 in Hardee County  is presented in  Figure 6.1-1.   The hydrograph from this
 USGS well shows seasonal fluctuations  as  high as 42 feet (between
 September 1974 and  May  1975).  In general,  there is an  increase  in the
 amplitude of the  drawdown  and recovery with  time.   According to  EPA
 (1978), this increase is attributed  to increases in irrigation pumpage
 since industrial  use generally does  not show seasonal  fluctuations.   The
 spatial variation of wet and dry  season water levels  is shown for  the

 season month;  Figure 6.1-3 presents the  level  in  September,  a wet  season
 month.  In May 1981, the potentiometric  surface of  the  Floridan Aquifer
 in  the Hardee  County area varied from 61  feet mean  sea  level (MSL)  in
 the northeast  corner of the county to 6  feet MSL  in  the  southwest
 portion of the county.   This lowering of  the potentiometric  surface  is
 attributed to  deep aquifer pumping for agricultural  use  and  citrus
 processing in  lower Hillsborough County,  according  to Southwest Florida
 Water  Management  District personnel (1982).

 In  September 1981,  after the heavy rains  of the summer,  the  potentio-
 metric surface had risen to 82 feet MSL in the northeast corner of
 Hardee County  and to 37 feet MSL in the southwest corner of  the county.
 This represents an increase between 21 feet and 31 feet  in the
 potentiometric surface  in the Floridan Aquifer from May  to September.
 During the dry season,  the major trend is generally  the  movement of  the
 low water  level contours inland and an increase in areas of major cones
 of  depression  (due  to pumpage).

 6.1.2   SITE-SPECIFIC DESCRIPTION—QUANTITY
 Ground  water is present to some degree in each of the geologic forma-
 tions  underlying  the CF site in northwestern Hardee County.  Some of the
 formations, however,  are capable of yielding significantly larger
 amounts of  water  than others.   There  are two minor aquifers within the
 upper  375  feet of sediment at  the site:   the shallow aquifer consisting
 of  undifferentiated  clastic  material;  and, the secondary artesian
 aquifer which  is  comprised of  limestone  material within  the Miocene
 Hawthorn Formation.   These  two  aquifers  are separated by a confining bed
 of  less permeable material  which tends to retard movement of water-
 between the aquifers.

At  depths  between about  AGO  feet  and  1,700 feet in the site area,  there
 are several geologic  formations  which  appear to function as a single
hydrologic  unit.  This  rock  interval which consists of limestone  and
                             6-8

-------
dolomite beds of the Tampa, Suwannee, Ocala, Avon  Park,  and  Lake  City
formations, constitutes the Floridan Aquifer.  The Floridan  Aquifer  is
the principal source of large ground water  supplies  throughout  the
region.  The stratigraphic relationships  of  aquifers  and confining  beds
at the CF site is summarized in Figure 6.1-4.  A detailed  explanation of
the chart and the logs shown therein is contained  in  the Consumptive Use
Application Supporting Report (CF  Industries,  Inc.,  1975).

Extensive ground water data have been collected on the  CF  property.
These data were collected in 1975  by Dames  and Moore  for the Application
for Development Approval/Development of Regional Impact (ADA/DRl) and
Consumptive Use Permit (CUP), and  since 1976 to present by CF Industries
for monitoring reports submitted to Hardee  County.  During the  DRI and
CUP investigations, 28 wells of varying depths were  installed in  the
shallow, secondary artesian and Floridan  Aquifers.  These  include:   a
Deep Floridan Test Well (DF), a production  test well  (PTW),  three wells
in the Floridan Aquifer (LF), five wells  in the secondary artesian
aquifer (UF), and 18 shallow aquifer (SA) wells.   Three wells were  later
added in the Floridan Aquifer,  increasing the  total  to  31  wells.  Since
installation in late 1975 and early  1976, 16 wells have been monitored
continuously and levels in the  remaining  wells have  been measured
monthly.  Included in the previous on-site  investigations  was a total of
28 pump tests:  18 on the shallow  aquifer,  2 tests on the secondary
artesian, and 8 tests on the Floridan Aquifer. The  locations of  the
on-sitj wells are presented  in  Figure 6.1-5.

Because of the large volume of  data  collected  and  available  for review,
investigations for this EIS were  limited  to drilling 6  corings to a
depth of 50  feet during the collection of samples  for radiation
analyses.  A geologic cross-section  was  prepared  from the drilling  on
the study area and is presented in Section 4:   Geotechnical.

-------
 The CF property (referred to as the site)  consists  of  Complex  1  (the
 north tract of land) and Complex II (the  southern area).  Complex  I is
 CF's existing mine, whereas Complex II (referred to  as  the  study area)
 is  the property being studied for this E1S.  The descriptions  of the
 site-specific aquifer systems presented in  this section are  based  on
 data collected by Dames and Moore during  the previous  studies, by  CF
 during continued monitoring, and by ESE during core  sampling and certain
 investigations conducted on Complex I in  its undisturbed  state.

 6.1.2.1   SHALLOW AQUIFER
 The shallow aquifer underlies the site area to depths  ranging  from 5  to
 40  feet.   Average thickness is about 30 feet.  The material comprising
 the aquifer is dominantly fine sand and clay with some coarse  sand,
 gravel and shell material.   The shallow aquifer is underlain by lime-
 stone beds of the Hawthorn Formation in some places  and by  phosphate
 matrix in others.   According to the Consumptive Use Application
 Supporting Report (CF Industries,  1975),  three wells on Complex II tap
 the shallow aquifer;  all three wells are  for domestic supply.

 During pump tests  of the 18 shallow wells by Dames and Moore,  pumping
 rates  ranged  from less  than 2 gallons  per minute to more than 50 gallons
 per minute.   Specific capacities,  which are a function of aquifer
 characteristics  and well efficiencies,  varied from less than 0.1 to
 about  3.6  gallons  per minute per foot  of drawdown.   Transmissivities,
 calculated  from  drawdown,  recovery,  and specific capacity data, ranged
 from less  than 200  to about 20,000  gallons per day per foot and averaged
 about  3,000.

 Storage coefficients  calculated  from drawdown data indicate that the
 shallow aquifer varies  from water-table to artesian  conditions  over the
                 — 1                   —8
 site area, 3 x 10    at  SA-ll  to  2 x  10    at SA-15.   This range
of  conditions  is a  result of  confining  beds due  to  variations in
 lithology  over the  site.  A summary  of  the resulting shallow aquifer
                                   i
hydrologic characteristics  is  presented in Table 6.1.2-1.

 The physical characteristics of the shallow aquifer were determined
 during the drilling of six cores at representative locations over the
 Complex II site.  A geologic cross-section prepared from the drilling on
 the study area is presented in Section 4:  Geotechnical.  The results
 show that the thickness and lithology of the shallow aquifer is similar
 to descriptions reported in previous studies.

 From 1976 to present,  water level  recorders were maintained by CF on 7
 shallow aquifer wells, 5 of which  are on the study area (i.e., SA-6,
 SA-8,  SA-10,  SA-15,  and SA-17)  and 2 are on the existing mine site
 (i.e.,  SA-1  and SA-3).

 The hydrograph  from  SA-17 is presented in Figure 6.1-6 for the monthly
 water levels  from January 1976  through June 1982.  The hydrograph
 indicates  that  the highest  level of 119.5 feet occurred during 1976,
 1978, 1979, and  1980,  while  the  lowest level of 114 occurred in 1976 and
 1981.   These  high and  low values correspond to a depth of 0.1 and 5.6
 feet, respectively, below the ground surface.  The effects of the  below
 normal  rainfall  (3-inch  deficit) during the dry season from October 1981
 through March 1982 is  seen  in the  general decline and  lack of
 fluctuations  in  the  shallow aquifer water levels during this period.

 The hydrographs  from the  shallow aquifer recorders  for the EIS study
 period  are shown  in Figure  6.1-7.   These hydrographs  indicate that from
 July 1981 through June 1982, levels  in the  shallow  aquifer varied by as
 much as 8  feet  in SA-10  and  about  4.5  feet  at  SA-8  and SA-17.   The large
 increase in levels in  most of the  wells  in  early and late August  1981  is
 the result of heavy  rainfall of about  3  inches  and  4 inches on August
 3-4 and August 20-24,  1981 respectively.

 The differences between  individual  wells  with  respect  to  the range of
 water level fluctuations  and response  to  rainfall probably  result  from
variations in the lithology  of the  shallow  aquifer  and on-site  rainfall

distribution.  The high water  levels  at  the  continuous  recorders on
Complex 11 ranged from 0 to 2  feet  below ground surface during September
1981.  The low water levels occurred  in  July 1981  and ranged from 4 to
9 feet helow ground surface.

Contour maps of the potentiometric  surface in the  shallow aquifer are
shown in Figure 6.1-8 for  the  wet  season (September 1981) and Figure
6.1-9 for the dry season (May  1982).   These  maps were developed from the
water level recordings and monthly  water elevation measurements in the
surficial aquifer wells, along with land surface topographic maps.  The
results of these contour maps  show  the water level gradient generally to
be about 10 feet per mile, sloping  downward  towards the north on the
east side of the property  and  downward towards the south on the west
side.  The highest potentiometric  surface is in the northwest area of
the study area, and the lowest is  in  the north-central  section where Doe
Branch intersects the property line.

6.1.2.2  SECONDARY ARTESIAN AQUIFER
At the CF Hardee site, the secondary  artesian aquifer consists of about
250 feet of alternating limestone  and clay within  the Hawthorn
Formation.  Examination of well cuttings and gamma-ray logs from wells
drilled on-site indicates  that in  most places the  secondary artesian
aquifer is overlain by clay beds at the  base of the shallow
undifferentiated elastics.  At the DF well in the  cluster area, the
thickness of the overlying clays is about 30 feet.  About 50 feet of
basal Hawthorn or upper Tampa  clays separate the water-bearing zones in
the Hawthorn Formation from the underlying Floridan Aquifer.

During the CUP investigations, static water  levels in the Hawthorn
differed by as much as 25  feet when both UF-2 and UF-3  were at approxi-
mately the same depth.  The reason for this  difference in water levels
is not well defined but could  be due  to  differences in well construc-
tion, water-bearing zones  within the  Hawthorn having different water
levels, or possible fracturing in the area.

 There was a wide range of results from pump tests conducted in Wells
 UF-3 and UF-2 suggesting that there may be appreciable differences  in
 water-bearing characteristics of individual zones within the secondary
 artesian aquifer.   For example, pumping rates  in  tests of UF-3 and  UF-2
 were 3.5 gallons per minute and 80 gallons per minute, respectively.
 Specific capacity was less than 0.5 gpm/ft at UF-3 and transraissivity
 ranged from 120 gpd/ft in the UF-3 test to 3,000 gpd/ft in the UF-2
 test.  After the pump tests were completed, UF-2 was deepened and is now
 also in the Floridan Aquifer.  A representative value for transmissivity
 of the secondary artesian at the CF site is most  likely about
 1,000 gpd/ft.

 Water level recorders have been maintained since January 1976 by CF on
 four wells  in the  secondary artesian, 3 of which are in the study area
 (i.e., UF-3,  UF-4, and UF-6) and one well, UF-5,  is on CF's existing
 mine site.   The hydrographs from these wells for the period July 1981
 through June  1982  are shown in Figure 6.1-10.  These hydrographs
 indicated that  during the year, levels in the secondary artesian varied
 only 7 feet at  UF-3 and as much as 18 feet at Wells UF-4, UF-5, and
 UF-6.

 At  the base of  the shallow aquifer and overlying the limestone of the
 Hawthorn Formation is an interval of clay material averaging about  30
 feet thick.   This  material acts as a confining layer for water in the
 underlying  artesian aquifer and also serves to retard downward movement
 of  water from the  shallow aquifer.

 The  effectiveness  of the clay as a confining layer is indicated by
 comparing secondary artesian wells with nearby wells in the shallow
 aquifer.  On  the east  and west  side  of the  study area,  the  difference
 between  the water  levels in the two  aquifers was about  62 feet in early
 July  and decreased  to  about 47  feet  in late September on an annual
 basis.   However, at UF-3 the water level was about 20 feet  below the
 shallow  aquifer during  the  entire  year.   Although the reason for the
difference  in the  water  levels  between UF-3 and the other secondary

 artesian aquifer wells is not well defined,  the water  levels in UF-3
 appear to respond more closely to the  shallow aquifer  water levels  than
 do the other UF wells.

 6.1.2.3  FLORIDAN AQUIFER
 The Floridan Aquifer is more than 1,300 feet thick at  the CF site in
 Hardee County.  This aquifer consists of limestone and dolomite beds of
 the Tampa,  Suwannee, Ocala, Avon Park, and Lake City Formations and is
 confined above by the clays at the base of the Hawthorn and the upper
 part of the Tampa Formations.

 Although the entire aquifer seems to behave as an interconnected hydro-
 logic unit,  there were minor differences measured in the potentiometric
 head between the Avon Park and Lake  City Limestones during CUP investi-
 gations,  suggesting the presence  of  a semi-confining bed within the
 aquifer.

 The  results  of  a series of pump tests and flowraeter surveys conducted in
 the  Floridan  Aquifer during the CUP  investigations showed that  there was
 a  significant difference  in water-yielding potential or permeability of
 the  various units.

 An aquifer  test  of the  Tampa Formation was conducted to evaluate its
 water-bearing characteristics  and the nature  of  the  overlying confining
 beds.   Static water levels  taken  prior to testing indicated a  similar
 potentiometric head  to  that  of  the underlying Suwannee Limestone but a
 significant difference  from that  of  the overlying Hawthorn.  For this
 reason,  the Tampa  Formation was included  within  the  Floridan Aquifer at
 the  site.

The  pump  test of  the Tampa  Formation  was  conducted using the airlift
 technique.  The  pumping rate was  measured  at  100  gpm  using  a 90*
V-notch weir.  Specific capacity  was  0.96 gpm/ft  and  transmissivity
calculated from  recovery data was 3,000 gpd/ft.
                             6-22

-------
Two short-term airlift pump tests were conducted in Well LF-3.  The zone
from 510 to 678 feet in the Suwannee Limestone was pumped at a rate of
about 1,400 gallons per rainute for each test.  Transmissivity values
calculated from the test using the recovery versus t/t! plot were 30,000
and 31,000 gpd/ft.  Because the airlifting technique results in more of
a constant drawdown than a constant production type of test, drawdown
data in the pumped well were not used to calculate aquifer
coefficients.

Two short-term airlift tests (one 10-hour test and one 6-hour test) in
conjunction with a flowmeter survey were conducted in the DF well.  The
pumping rate for both tests was about 2,000 gallons per minute.  The
zone tested was from depths of 519 to 1,073 feet below ground surface
and included Suwannee Limestone, Ocala Group, the Upper Avon Park
Limestone, and the top 50-feet of the Avon Park dolomite unit.  Results
of the flowmeter data are shown in Figure 6.1-11.

The transmissivity calculated during a 10-hour test for the entire
interval was approximately 190,000 gpd/ft.  The flowmeter indicated that
about 31 percent of the flow was from the Suwannee, 7 percent from the
Ocala, 15 percent from the Upper Avon Park Limestone, and about
47 percent from the top 50-feet of the Avon Park dolomite.  Based on
these percentages and a total transmissivity of about 190,000 gpd/ft,
the following transmissivity values were calculated for the individual
formations:
     Suwannee Limestone                       T -   59,000
     Ocala Group                              T -   13,000
     Upper Avon Park Limestone                T -   29,000
     Top 50 feet of Avon Park dolomite        T »   89,000
     TOTAL                              Total T -   190,000

During the 10-hour airlift test, drawdown and recovery data were
collected in Well LF-3 about 850 feet south of the  pumping well.
Assuming 31 percent of the flow was from the Suwannee, a transmissivity

of 24,300 gpd/ft was calculated from drawdown data  and  37,000  gpd/ft
from recovery data.  Also, a storage coefficient  of 0.00005  for  the
Suwannee was calculated based on the drawdown data.

Total transmissivity for the 6-hour test  at  the DF  well was
approximately 170,000 gpd/ft.  Using the  method previously discussed,
transmissivities for individual formations were as  follows:
     Suwannee Limestone                       T =     53,000
     Ocala Group                              T =     12,000
     Upper Avon Park Limestone                T =     25,000
     Top 50 feet of Avon Park dolomite        T =     80,000
     TOTAL                              Total T =    170,000
Additional zones of the Floridan Aquifer  were  tested  using  airlift
pumping in combination with another  flowmeter  survey.   An average of
3,200 gallons per minute was  pumped  from  depths  between 514  and  1,356
feet.  Total transmissivity for the  zone  which  included the  complete
Avon Park dolomite, was calculated  from recovery data in the DF  well.
The calculated value of 2,600,000 gpd/ft  is  basically a value for  the
highly transmissive dolomite  zone.

A final flowmeter survey was  conducted when  the  DF  well reached  a  total
depth of 1,702 feet.  The zone tested was  between 514 and  1,702  feet and
included the Suwannee, Ocala, Avon  Park,  and part of  the Lake City
formations.  Approximately 3,700 gallons  per minute were pumped  using
the airlift method.  A total  transmissivity  of  about  3,800,000 gpd/ft
was calculated based on recovery data from the  DF well.  Since this
number appeared high compared to other test  results,  a second
calculation utilizing the specific  capacity  method  (USGS,  1962)  was
made.

Specific capacity, or discharge divided by drawdown in the  pumping  well,
was equal to approximately 925 gpd/ft.  The  calculation was  based  on a
pumping rate of 3,700 gpm and a drawdown  in  the  DF  well of  4 feet.
                               6-25

-------
 Drawdown in the well was determined by using a down-hole pressure sensor
 which measures the change in formation pressure and  thus cancels out
 drawdown due to friction loss of water moving up-hole.  Transmissivity
 based on a specific capacity of 925 gpd/ft and storage coefficient of
 0.00005 was about 2,100,000 gpd/ft which is in line with previous
 calculated values.

 A 1,000 gallon-per-rainute airlift test was performed for 11 hours in
 LF-3.  The pumping well was  cased to 950 feet and had open hole to a
 depth of 1,121 feet.   Transmissivity calculated from recovery data was
 for the Avon Park Limestone  and approximated 880,000 gpd/ft.

 During a 12-hour  pumping test of Lake City Limestone conducted in the DF
 well,  approximately 40 gallons  per minute were  pumped from the zone
 between 1,500  and  1,702 feet using the airlift  method.   After 12 hours
 of  pumping,  there  was  a total drawdown of about 58 feet giving a
 specific  capacity  of about  17 gpd/ft.   Calculations made from recovery
 data  show that  transmissivity for the Lake  City Limestone is about
 1,400  gpd/ft,  significantly  lower than that for the overlying Avon
 Park Limestone.

 A large scale  pump and  recovery test  of the Avon Park limestone and
 dolomite  was conducted  at the CF  site  in  Hardee  County  beginning
 December  13, 1975  and  continuing  for  six  days of pumping and six days of
 recovery.  Water was pumped  from  the  Production  Test  Well  (PTW) at  a
 constant  rate  of about  5,700 gallons  per  minute.   Thirty-eight
 observation wells  (including 18 shallow aquifer  wells on the CF
 property) at varying distances  and  direction  from  the PTW were used  to
monitor water  levels in the  shallow aquifer,  the Hawthorn  Formation,  the
 Tampa  Formation, the Suwannee Limestone,  the Avon  Park  Limestone, and
 the Lake  City Limestone.

An observation well 15,000 feet to  the  west-northwest of  the cluster  was
the only outlying  well  which reacted  to the pump test.   Its  corrected
                             6-26

-------
drawdown of 2.3 feet is considered large in comparison to drawdowns of
3.5 and 3.3 feet for two wells which are 414 feet and 990 feet,
respectively, from PTW.

Because anisotropic conditions were encountered, dolomite aquifer
characteristics of transmissivity and storage coefficient and leakage
for confining beds could not be calculated by normal radial flow ground
water hydrology analytical methods.  In order to obtain an indication of
the magnitude of the transmissivity of the "permeable zone" between a
well 15,000 feet from the test well cluster, Darcys Law Q=TIW was used
and a transmissivity value of 20,000,000 gpd/ft was obtained.

Variability within the "permeable zone" is shown by the specific
capacity (SC) of PTW and DF which are located only 153 feet apart.  The
DF test well had only 4 feet of drawdown for a pumping rate of 3,700 gpm
(SC = 925 gpm/ft) whereas PTW had a drawdown of 20 feet for 5,700 gpm
(285 gpm/ft).  However, during the PTW pumping test, a test well cluster
area drawdown of only 3.3 feet occurred (SC = 1,727 gpra/ft).

Outside of the permeable zone, traosmissivities are lower and may be on
the order of 500,000 gpd/ft or less.

A composite or areawide transmissivity value for the low and high value
zones combined may exceed 2 million gpd/ft based upon specific capa-
cities, potentiometric contours, and previous flow meter surveys
conducted.

The storage coefficient for the Floridan Aquifer has been estimated to
be 0.001 and 0.01 based upon the drawdowns observed.  This is considered
a high artesian storage value but is believed to be reasonable due to
the great aquifer thickness which exceeds 1,300 feet.  A reliable
leakage value cannot be obtained from the PTW pumping test.
                             6-27

-------
 Based upon  the  large-scale  pump test (6 days)  data collected  on  the
 production  test  well  and  the  analyses completed,  the  following
 conclusions have been  reached:
      1.  The Avon Park dolomite is  very much  anisotropic  such that  a
          "permeable zone" trends  west-northwest between the test well
          cluster and an area  about  one-half mile  north of LP-4.
      2.   The highly permeable zone  probably controls  potentiometric
          water level contours.  This  is  illustrated by water  level
          contours plotted for Hardee  County (Wilson,  1975).
      3.   Identical Suwannee water level  responses  at  the cluster
          indicate that the "highly  permeable" zone penetrated by PTW is
          greater than 1,200 feet wide.
      4.   The Floridan Aquifer includes geologic formations from the Lake
          City Limestone up through the Tampa Formations indicated by
          pumping water level responses in these formations.  The total
          thickness exceeds 1,300 feet.
      5.   A confining bed exists  between the Floridan Aquifer and
          secondary artesian  aquifer  as indicated by Hawthorn water
          levels  monitored  during the PTW pumping test.
      6.   Transmissivities  of the Avon Park dolomite may range  from less
          than 500,000  to more  than 20,000,000  gpd/ft on an areal  basis.
          The  storage coefficient is  believed  to be in  the  order  of 0.001
          to  0.01.  A leakage value for confining beds  bounding the
          Floridan Aquifer  was  not  calculated based upon the PTW  pumping
          test.
      7.   Determination  of  pumping  levels for  pumping rates  other  than
          5,700 gpm can  be  extrapolated directly  from plots  of  the  pump
          test data.

Water level  recorders have been  maintained  since February  1976 by  CF on
5 wells in the Floridan Aquifer.  One of these  wells is  in  Complex I
(LF-5), and  the  remaining  four wells are on Complex II (LF-1,  LF-4,
LF-6, and DF).  The  hydrograph from  LF-4 is presented  in Figure 6.1-12
for the period from  February 1976  through June  1982.   The  hydrograph
indicates that the highest level (55.5 feet MSL) occurred  in October
                                    6-28

 1980  and the lowest level (15.5  feet MSL)  occurred  in May  1981.   The
 general trend of the levels does not indicate  a  decline  in  the overall
 potentiometric surface over the  six-year period.  The low water  level  in
 May 1981 corresponds with a regional drought in  which heavy  agricultural
 pumping occurred west of the site according to Southwest Florida  Water
 Management District personnel (1982).

 The hydrology from LF-1,  LF-4,  and LF-6 for the  period from  July  1981
 through June 1982  are shown in Figure 6.1-13.  LF-5 was not  included on
 the figure because its  water level was nearly identical (within  1  foot)
 of  LF-6.   The water level for Well DF was  between the water  levels
 recorded  at LF-l  and LF-4 for the entire year.

 The hydrographs  indicated that  during the  study  period, levels in  the
 Floridan Aquifer  fluctuated  about 21 feet.   The highest level was  at
 LF-6 (63 feet MSL)  and  the lowest was at LF-4 (30 feet MSL).  The
 gradient of  the  potentiometric  surface  across the property is about
 1 foot/mile  pitching downward in the southwestern direction.

 Water-bearing zones  in  the  secondary artesian are separated  from the
 underlying  Floridan Aquifer  by  about 50 feet of basal Hawthorn or upper
 Tampa clays.  The  effectiveness  of  the  clays as confining material is
 indicated  by  significant  differences in water levels measured in the
 two aquifers.  The  less  permeable material  in the second  confining bed
 tends to retard  downward  movement of water  from the Hawthorn Formation
 into the Tampa Formation.

This resistance  to  downward  movement on the west side of  Complex II with
head differences as  great  as 55  feet,  appears  to be  greater than the
east side  where  the  head  difference  was a maximum of 8 feet.  However,
 this difference  could be  due to  greater drawdowns on the  west side from
the long pumping center on  the Hillsborough/Manatee  County line,  as
shown in Figure 6.1-2.

-------
 The resulting head differences measured between the shallow aquifer and
 Floridan Aquifer was also greater on the western portion of Complex II
 (as high as 87 feet) than on the eastern area (maximum measured was
 about 71 feet).

 6.1.2.4  RECHARGE AND WATER MOVEMENT
 Precipitation is the ultimate source of recharge to the ground water
 system at the CF project area.  The shallow aquifer contains water
 derived from direct  recharge of local precipitation.  Water entering the
 shallow aquifer by infiltration moves laterally in a direction that is
 controlled  for  the most  part by topography.  After the periods of high
 rainfall, water generally moves through the shallow aquifer into the
 surface drainage courses to  provide base flow to the streams on
 Complex II  for  several weeks.

 Recharge  of  the  secondary artesian aquifer is supplied by downward
 movement  of  water  from the shallow aquifer and by lateral movement of
 water  from  areas  to  the  north  and east  where the potentiometric surfaces
 of  both  the  secondary artesian and Floridan Aquifer are higher (Wilson,
 1975).  The  principal for both vertical and lateral movement is
 essentially  the  same  in  that water moves in the  direction of decreasing
 head.   For  example,  at the CF  site,  July 1981, the water level in the
 shallow aquifer  (approximately 116 feet MSL) was about 62 feet above the
 water  level  in  the secondary artesian aquifer (approximately 54 feet
 MSL).   Thus,  water from  the  shallow aquifer had  the potential  to move
 through the  first  confining  bed and  into the secondary artesian aquifer
 in  response  to  the vertical  hydraulic gradient.

 Recharge  to  the  Floridan Aquifer  also occurs both laterally and
 vertically.   Lateral  inflow  is  from  the north and  east where
 potentiometric  levels are higher  than at the project area.   There is the
potential on  the site for vertical  recharge through the confining beds
and the secondary  artesian aquifer into the Floridan Aquifer.
                                      6-32

-------
The difference in potentiometric head above  and  below confining  beds  in
combination with the vertical permeablilLtes of  the  confining  beds
control the rate or amount of water moving through the system.   During
the study period, July 1981 through June  1982,  the head  difference  was
observed to be greater on the western portion of the property  (therefore
it had a greater recharge potential), than on the eastern  portion.

Even though a downward gradient exists on the site,  the  results  of  the
CUP pump tests indicate that no measurable leakance  occurs in  the  site
area.  This is attributable to the confining beds between  the  aquifers.

An inventory of water wells was conducted to determine the location,
depth, and other pertinent information about water wells in the  vicinity
of the project site.  A summary of water  well data  is presented  in
Table 6.1.2-2, Inventory of Wells in the  Vicinity of CF  Industries'
Hardee County Phosphate Project Site (CF  Industries, Inc.  1975).  Well
locations are shown on Figure 6.1-14.

6.1.2.5  SUMMARY
One major and two minor aquifers underlie the CF Hardee  phosphate
project site in northwestern Hardee County.  The major aquifer  is the
Floridan Artesian Aquifer.  The minor aquifers  are  the shallow aquifer
and the secondary artesian aquifer.  The  aquifers are separated  by
confining beds.

The Floridan Aquifer consists of more than 1,300 feet of limestone  and
dolomite within the Tampa, Suwannee, Ocala,  Avon Park, and Lake  City
Formations.  The aquifer is confined above by clays  of the basal
Hawthorn or Upper Tampa Formations.  Static  water level  measurements,
pump tests and flowmeter surveys indicate that  differences in
potentiometric head exist between formations and that there are  signifi-
cant differences in permeabilities within the aquifer.  A  representative
transmissivity for1 the entire Floridan Aquifer  at the CF site  is more
than 2,000,000 gpd/ft.  Transmissivities  for the individual formations
                                    6-33

are as  follows:  Tampa—3000 gpd/ft;  Suwannee—30,000 to 50,000 gpd/ft;
Ocala—12,000 gpd/ft;  Upper Avon Park Limestone—25,000  god/ft; Avon
Park dolomite—approximately 2,000,000 gpd/ft; and  part  of the Lake  City
Limestone—1,400 gpd/ft.

The secondary artesian aquifer consists  of  about 250  feet  of alternating
limestone and clay within the Hawthorn Formation and  is  confined above
by clay beds at the base of the shallow,  undifferentiated  clastic
material.  A representative transmissivity  for the  secondary artesian
aquifer at the site is 100 gpd/ft.

The shallow aquifer underlies most of the CF property varying in thick-
ness from 15 to 40 feet.  Lithic compositon is dominantly  clay and  fine
sand with some coarser sand and gravel.   Rvalution  of data collected
during  18 shallow aquifer tests indicated that the  aquifer exhibited
both artesian and water-table characteristics and that  a representative
transmissivity would be about 3,000 gpd/ft.

Table 6.1.2-3 is a summary of the physical  and hydrological  properties
of aquifers and confining beds at the  CF  Hardee phosphate  project area.

The ground water monitoring of the potentioraetric surface  in the
shallow, secondary artesian aquifer and  Floridan Aquifer from July  1981
through June 1982 indicated that the  site is in a recharge condition.
The head difference between the shallow  aquifer and Floridan Aquifer has
a downward gradient and, in July 1981, was  as high  as 87 feet  on the
western portion of the site and about  71  feet on the  eastern portion.
The smallest difference between the potentiometric  surfaces  of the
shallow and deep aquifers was in September  1981 when  the shallow aquifer
was about 65 feet above the Floridan Aquifer.

6.1.3  REGIONAL DESCRIPTION—QUALITY

overpuraping of public-supply wells have resulted  in  local  degradation  of
some areas through contamination.  The EPA (1978)  document  presents  an
overview of the ground water quality in the region.   The  following
section presents summaries of descriptions from  this  overview  on  the
shallow (also called the surficial or water table) aquifer,  secondary
artesian aquifer and the Floridan Aquifer.

6.1.3.1  SHALLOW AQUIFER
The water in the Shallow Aquifer is generally  soft and has  a low
dissolved-solids content (less than 100 milligrams per liter)  in  the
inland areas.  The shallow aquifer is contaminated locally from
nutrients from fertilized agricultural land, and  leakage  from  sewers,
seepage from industrial lagoons, septic systems,  and  landfills.
Contamination of the shallow aquifer is generally evidenced  by increased
concentrations of dissolved constituents  such  as  chloride,  nitrate,
fluoride, phosphate, sulfate, and, in some areas,  bacteria and viruses
(U.S. Army Corps of Engineers, 1977).

In Hardee and DeSoto Counties, the shallow aquifer is believed to
increase in thickness from north to south and  is  capped  at  a depth
between 40 to 65 feet.  Wells completed in the shallow aquifer are
generally used for domestic purposes, lawn-watering,  or  stock-watering.
In general, this aquifer has high iron concentrations and  has  a pH  value
below 7 (i.e., it is slightly acidic).

6.1.3.2  SECONDARY ARTESIAN AQUIFER
Regional water quality data for  the secondary  artesian aquifer are
limited and most of the existing information  is  combined  with  the
results of sampling in the lower Floridan Aquifer.   The  secondary
artesian aquifer is widely used  as a source of water, although yields  of
individual wells and total withdrawals from this  aquifer  are generally
less than those associated with  the Floridan  Aquifer (USGS, 1977).
                                     6-41

-------
 In general, water  quality  in  the  secondary artesian aquifer is better
 than  that  of  the Floridan  Aquifer.   The median values for dissolved
 solids,  calcium and magnesium,  sulfate, and hardness are all
 substantially  less  for  the secondary artesian aquifer.   Median concen-
 trations of chloride  and sodium are  nearly equal  to slightly lower  while
 fluoride concentrations are slightly higher in value (see
 Table 6.1.3-1).

 6.1.3.3  FLORIDAN AQUIFER
 The Floridan Aquifer  is an underground  freshwater reservoir which
 extends under the entire peninsular  portion of the  state.  Under  natural
 conditions, highly mineralized  water underlies the  Floridan Aquifer at
 various depths.  As shown  in  Figure  6.1-15,  water obtained  on-site  from
 the Floridan Aquifer  generally  can be used as potable water,  e.g.,  it
 provides the public water  supply  for the  City of  Arcadia.  However,  in
 the coastal areas (0-10 miles inland) from Hillsborough  County to
 Charlotte County,  the Floridan  Aquifer  contains essentially no potable
water.

 In coastal  areas where drainage canals  and tidal  channels,  as  well  as
 pumping near the coast,  have reduced the  potentiometrie  head,  saltwater
 intrusion is an important  concern.   As  a  result of  these influences,  a
 saltwater wedge has migrated  inland.  The  pumping of  the deep  aquifer
water for irrigation  is largely responsible  for inland saltwater
 intrusion in the Floridan Aquifer.

The following discussion of ground water  quality  of  the  Floridan Aquifer
in Hardee and DeSoto Counties  is extracted  from EPA  (1978):

     Within the Floridan Aquifer,  dissolved-solids  concentrations
     generally increase  from northern Hardee  County toward  southern
     DeSoto County  and also increase with  depth.  Concentrations exceed-
     ing 500 milligrams  per liter  occur in  the upper  part of the Aquifer
     in southeastern and southwestern HeSoto  County,  in  the  lower
     Floridan Aquifer, along the Peace  River,  in  the  southern  part of
     Hardee County, and  in all of DeSoto County.  The water  temperature

generally increases from northern Hardee  to  southwestern DeSoto
County, as well as with depth.  The water  underlying  Hardee and
DeSoto Counties is generally hard because  of the  predominance of
calcium- and magnesium-rich limestone  and  dolomite  in the matrix.
Generally, water from the upper part of the  Floridan  Aquifer is
moderately hard to hard (61 to 180 milligrams per liter)  in north-
ern Hardee County, increasing in hardness  toward  southern DeSoto
County where the water is very hard (exceeding 500  milligrams per
liter).  Within the lower part of the  Floridan Aquifer,  the only
moderately hard to hard water occurs in the  northeast corner of
Hardee County, with hardness increasing toward the  southwest.

Sulfate concentrations in Hardee and DeSoto  Counties  generally
increase with depth.  Most is probably derived from the  solution of
gypsum and anhydrite (calcium-sulfate  minerals)  found in the lower
Floridan Aquifer.  In the upper Floridan,  concentrations  generally
increase from north Hardee to southwest DeSoto.   Southwest of
Arcadia, concentrations range from 100 to  more than 250  milligrams
per liter.  Only in the northern half  of  Hardee  County does water
from the lower Floridan contain less than  100 milligrams  per liter
of sulfate.  A zone exhibiting more than  250 milligrams  per liter
extends across southernmost Hardee County, northern DeSoto County,
and along the Peace River valley, with the water  in most  of south-
ern DeSoto County containing less sulfate  (101-250  milligrams per
liter).

Chloride concentrations in the Floridan Aquifer  in  Hardee and
DeSoto Counties generally are less than 50 milligrams per liter
although in areas south of Arcadia they range from  50 to  250 milli-
grams per liter and near the southwest Sarasota-DeSoto County line
exceed 250 milligrams per liter.  Concentrations  of fluoride in the
Floridan Aquifer underlying the two counties form a concentric
pattern, increasing toward the center. In both  the upper and lower
Floridan Aquifers, concentrations are  0.8  milligrams  per  liter or
less only along the periphery of Hardee and  DeSoto  Counties (except
along the western boundary where concentrations  are higher).  In
much of the central area along the Hardee-DeSoto  County  line,
Aquifer concentrations in the upper Floridan exceed 1.4  milligrams
per liter (and some exceed 2.0 milligrams  per liter).  In the lower
Floridan, concentrations exceeding 1.4 milligram  per  liter are
restricted to western DeSoto County.   The  principal source of
fluoride in Hardee and DeSoto Counties is  fluorapatite,  a mineral
restricted to rocks of the upper Floridan  Aquifer and younger
deposits.  Fluorapatite is the principal  source mineral  of phos-
phate in the land-pebble raining district  of  central Florida.

 6.1.4   SITE-SPECIFIC DESCRIPTION—QUALITY
 6.1.4.1  DATA COLLECTION
 Previous  Studies
 As  part of the previous studies on the OF property, extensive ground
 water  quality data  have been collected.   During the CF DRI and the CUP
 investigations by Dames and Moore, water quality data were collected
 during aquifer pump tests.   From early 1976 until June 1982 monthly
 ground water  samples  were  collected from 18 shallow aquifer wells (SA-1
 through SA-18),  4 secondary artesian aquifer wells (UF-3 through UF-6),
 and  7  Floridan Aquifer  wells (UF-2,  LF-1,  LF-4, LF-5,  LF-6, OF,  and
 PTW) .   Well UF-2 was  originally a secondary artesian well  that was
 re-drilled  to  the present  depth of 443 feet.  It is in the uppermost
 area of the Floridan  Aquifer.   The monthly analyses conducted on these
 samples include:  temperature,  pH, ammonia,  nitrite, nitrate, ortho-
 phosphate,  total  phosphorus,  sulfate,  alkalinity (bicarbonate and
 carbonate), dissolved silica,  total  dissolved solids (TDS), fluoride,
 and conductivity.

 Semi-annual analyses  from early 1976 until June 1982 were  also conducted
on seven of the  shallow aquifer  wells  (SA-1, 2, 3,  4,  6, 8,  and  17),
 three  secondary  artesian wells  (UF-4,  UF-5,  and UF-6)  and  five Floridan
Aquifer wells (LF-4, LF-5, LF-6;  PTW,  and  OF).   These  semi-annual
analyses include  calcium, magnesium,  sodium,  potassium,  chloride,  iron,
and strontium.   Radium-226 sampling  is discussed  in Section 5.0—
Radiation.

EIS Monitoring
Because of  the detailed and  continuing  field monitoring  program,
monitoring for the EIS was limited  to  split  sampling with  CF  from  one
shallow aquifer  well  (SA-17), one  secondary  artesian well  (UF-4),  and
one Floridan Aquifer well (LF-4).  ESE and CF analyzed these  samples for
all parameters in CF's monthly  and' semi-annual  parameter list  (see  Table
6.1.4-1).   In addition, ESE analyzed the samples  for metals.

The wells were sampled by  the  same  procedure  that  CF  uses  during monthly
sampling.  The method used  by  CF  to extract  the  samples  utilized a thief
sampler.  This sampler consisted  of a  bailing  device  which allows  the
sample to be extracted from a  selected depth.  The wells are  not pumped
before sampling in order to obtain  an  undisturbed  sample from a
discrete depth interval.   In general,  the  split  sample analyses compare
moderately favorably.  Major differences exist in  the analyses of
cations and anions.  A cation-anion balance was  calculated and is
included in Table 6.1.4-1.

6.1.4.2  DATA ASSESSMENT
Shallow Aquifer
The 18 Shallow Aquifer wells were divided  into 3 groups  for discussion
purposes:
     1.  Complex I,
     2.  Complex II-East, and
     3.  Complex Il-West.

Details of well depths and  location can be found in Table  6.1.4-2.
Complex I included Wells SA-1  through  SA-4, which  range  in depth from  25
to 51 feet and have monitor  zones between  5 and  51 feet  below the
surface.  Complex II-East included  Wells SA-5  through SA-10 and ranged
in depth from 35 to 66 feet with  monitor zones between 5 and  66 feet.
Complex Il-West included Wells SA-11 to SA-18  and  ranged in depth  from
45 to 66 feet with monitor  zones  between 5 and 66  feet.

The mean concentration of the  analyses conducted by CF for the 18
shallow aquifer wells are summarized for July  1981 through June 1982 in
Table 6.1.4-3.  The monthly  analyses used  to compile  this  table are
presented in Appendix A to  this report.

Average total dissolved solids (TDS) concentrations were somewhat
variable with location as a direct  function of the substrate  (i.e.,
carbonaceous versus clayey  or  siliceous) characteristics of the aquifer.
Linear regression analysis  indicates a highly  significant  correlation

between TDS and alkalinity (r2 = 0.74, p<0.01).  The average IDS
levels in Complex I was 83 rag/1.  TDS concentrations in Complex II-West
and Complex II-East show a gradation of increasing TDS concentrations
with observed average values of 164 and 190 mg/l, respectively.

Specific conductance, which is a measure of the electrical activity of
dissolved constituents (i.e., TDS), was highly variable in the shallow
aquifer, ranging from 17 to 570 umhos/cra.  Variability in conductivity
was consistent with TDS levels and the observed range agrees with values
predicted from TDS concentrations.  Complex I had the lowest values,
with an average value of 114 umhos/cm; conductivities observed in
Complex II-East and Complex 11-West were approximately the same with
average values of 222 and 192 umhos/cm, respectively.

Sulfate levels were highly variable, ranging from 1 to 123.3 mg/l.
Average sulfate levels were approximately the same within the Complex I
and Complex II-East groups.  Average sulfate concentrations ranged from
11.2 to 13.7 mg/l for Complex I and Complex II-East, respectively.
Observed levels within the Complex II-West (Horse Creek basin) were
substantially lower; sulfate concentrations during the study period
averaged 4.1 mg/l.  Well SA-18 within the Horse Creek basin exhibited
apparently anomalous behavior; sulfate concentrations detected at this
location averaged 13.3 mg/l and ranged as high as 123 mg/l.

Fluoride levels ranged from 0.06 to 1.16 mg/l, with little difference
observed between the three sampling complexes.  No correlation between
fluoride and phosphorus was observed.  Florida Class G-II ground water
quality criteria for fluoride is 1.6 mg/l; no violations of this
criteria were observed.

Nutrients
Three inorganic forms of nitrogen (i.e., ammonia, nitrate, and nitrite)
were analyzed in the shallow aquifer.  Elevated concentrations of
nitrogen generally reflect anthropogenic inputs (primarily fertilizer)
                                    6-51

-------
 from surface water seepage.  Ammonia levels ranged from O.OS to 0.50
 mg/1 with many of the higher measurements occurring in Goranlex II—East.
 Oxidized nitrogen (nitrate-nitrite) is primarily in the form of the more
 stable  nitrate (0-3 mg/1);  nitrite ranged from 0 to 0.094 mg/1.  In
 general, average nitrate and nitrite levels were quite low and, with the
 exception of Wells SA-5, SA-7,  SA-11,  and SA-14, were less than 0.05
 mg/l.  The highest average  concentration was observed in SA-14 with a
 reported average value of 0.30  mg/1.  Florida Class G-II ground water
 quality criteria for ground water nitrate is 10.0 mg N/l; no violations
 of  this standard were observed.

 As  expected,  total  phosphate concentrations were relatively high,
 ranging from 0 to 7.7 rag/I  with the highest measurement occurring  at
 Well  SA-7  in Complex II-East.   Average TP concentrations were highest in
 Complex II-East  (1.95 ragP/1).   Orthophosphate levels  also were high with
 the  highest  average  concentration detected in Complex II-West (0.74
mgP/1).  Average  concentration  on Complex II-East was 0.59 ragP/1 while
 the  lowest average value  was  in Complex I (0.33 tngP/1).   The spatial
distribution  of  orthophosphorus did not conform to any discernible
 pattern, but  showed  a great  deal  of variability even  within a particular
drainage basin.   Average  concentrations by station ranged from 0.06 mg/l
(SA-11)  to 1.78 mg/l  (SA-16).   Well  SA-7 had  the two  highest  individual
readings of 7.6 and  3.0 mg/l which  occurred  in October and November of
1981.   No correlations of total  and  orthophosphorus were  observed.

Alkalinity and pH
Alkalinity was generally  in  the  form of bicarbonate,  the  predominant
form of  carbonate below a pH value  of  8.3.   Carbonate  alkalinity was
measured in Well  SA-11 (Complex  II-West)  during the months of July  and
August  1981 when  pH  reached  8.5  and  8.4,  respectively.   Bicarbonate
alkalinity was highly  variable,  ranging from 0.3 to 342.5  mg/l  as
CaC03.   The high  degree of  variability apparently is  a reflection of
the heterogeneity of  the  shallow aquifer  lithology.
                                  6-52

-------
Average alkalinity was highest in Complex  II-West  with  an  average
concentration of 86.5 mg/1 as CaC03 observed.   Average  alkalinities  by
station were relatively low within Complex I and did  not exceed 25 mg/1
as CaCO-j.  Highest average alkalinities by station were observed in
SA-11 (322 mg/1 as CaC03) and SA-18 (177 mg/1  as CaC03).

Measurements of pH reflect generally acidic conditions; pH ranged from
4.9 to 8.5.  Average pH levels for Complex I and Complex II were similar
and ranged between pH 6.1 and pH 6.6.  No  basin-wide  differences were
apparent; however, some wells reflect basic conditions  (SA-11  and SA-18)
as a function of high ambient alkalinity concentrations.   Acidic
ground water is probably the result of seepage  of  colored  acidic surface
waters into the shallow aquifer.  The amount of alkalinity (acid
neutralization) also will determine pH.

Secondary Artesian Aquifer
Secondary artesian wells included UF-3 through  UF-6 and ranged in depth
from 360 to 418 feet (see Table 6.1.4-2),  with  monitor  zones between 65
and 418 feet.  A summary of the data from  samples  collected at these
wells from July 1981 through June 1982 is  presented in  Table 6.1.4-4.

Dissolved Ions
Average conductivity values are comparable in  Stations UF-3 to UF-6
(423 to 629/umhos/cm).  Sulfate levels were similar in  the wells and
ranged from 0.2 to 29.1 mg/1.

Average fluoride levels were twice as high in  Wells UF-3,  UF-4, and  UF-5
(2.03 to 2.31 mg/1) as Well UF-6 (1.14 mg/1).   The Florida Class G-II
criteria for fluoride in ground water (1.5 mg/1) was  exceeded  in all of
the samples from Wells UF-3, UF-4 and UF-5; observed  concentrations  in
Well UF-6, however, were substantially lower and did  not exceed
criteria.

Nutrients
Ammonia, nitrate and nitrite concentrations  were  measured at  all
stations.  Average ammonia levels were relatively constant between
stations ranging from 0.10 to 0.34 mg/1, with  values  generally lower  at
UF-6.  Nitrite was generally less than 10 ug/1; however,  two  somewhat
elevated peaks (69 and 78 ug/1) were observed  at  two  sampling points.
Nitrate was also observed to have relatively high peaks  (UF-4,  UF-5)  but
generally remained below 0.07 mg/1.  No violations of the Florida
Class G-II nitrate criteria (10 rag N/l) were observed.

Average total phosphorus levels were somewhat  variable between stations
and ranged from 0.21 to 0.63 mgP/1.  Minimum concentrations were
observed in Well UF-3; total phosphorus concentrations in the remaining
wells were approximately a factor of 2 to 3  times higher.  Average
orthophosphate was found at similar levels at  all stations and ranged
from 0.07 to 0.13 mgP/1.  No correlations between total  and
orthophosphate were observed.  In addition,  no relationship was observed
between orthophosphorus and fluoride concentrations,  thus suggesting
that some other mineral phase besides fluorapatite controls the aqueous
solubility of these two species in the secondary  artesian aquifer.

Alkalinity and pH
Alkalinity was found predominantly as bicarbonate, however, depending
upon the pH levels at each station, some carbonate alkalinity was
measured.  The mean pH levels were all alkaline,  as would be  expected,
ranging from 7.9 to 8.2.

Floridan Aquifer
The Floridan Aquifer well group included Wells LF-1 through LF-6, UF-2,
PTW, and DF.  The other wells range in depth from 948 to  1,702 feet  (see
Table 6.1.4-2).  Wells LF-2, LF-3, and DF have monitor zones  at multiple
depths, and the remaining wells have monitor zones between 374 and
1,200 feet.  A summary of the mean concentration  of data  from samples
collected from each well during monthly sampling  from July 1981 through
                                     6-55

-------
 June 1982 is presented in Table 6.1.4-5.  The results of water quality
 sampling during purap tests conducted in 1975 are presented in Table
 6.1.4-6.

 Dissolved Ions
 Conductivity values in UF-2 were high with an average concentration of
 1,765  umhos/cm,  and may be the result of subsurface contamination.
 Average conductivity levels ranged from 301 to 363 umhos/cm in Wells
 LF-1,  LF-5,  and  LF-6.   Observed conductivities in Well LF-4 were
 somewhat higher,  averaging 539 umhos/cm.  Well DF was much higher and
 averaged 1,550 umhos/cm;  this  value of  conductivity probably reflects
 saltwater intrusion at  the deepest level.

 IDS  levels were  also generally much higher in Wells UF-2 and DF; an
 average concentration of  750 and 1,240  mg/1 was observed in Wells UF-2
 and  DF,  respectively, compared with average TDS levels ranging from 202
 to 413 mg/1  in the  remaining Floridan Aquifer wells.  The federal
 secondary drinking  water  standard  for TDS  is 500 mg/1 for primarily
 aesthetic reasons;  water  from  these two wells is unsuitable for drinking
 purposes.  No  general trend of increasing  TDS with depth was  observed
 except  for Well DF.

 Sulfate  levels in Wells UF-2,  LF-1,  LF-4,  LF-5,  LF-6, and PTW were
 variable  and ranged from  0 to  60.3 mg/1.   No  pronounced  differences  were
 apparent  between these wells;  however,  Well  DF,  which was the deepest
 Floridan  Aquifer well, exhibited much higher  levels  which ranged  from
 407.6  to  1,561 rag/1 at the deepest level.   High sulfate  levels generally
 reflect dissolution of sulfate  minerals (e.g.,  gypsum and anhydrite)  or
 may  be  indicative of saline intrusion.   Using chloride as a tracer for
 saline  intrusion (see Table 6.1.4-6)  indicates  that  the  accretion of
 sulfate  in the Floridan Aquifer is primarily  marine  in origin.  This  is
 not  true  for Well DF where  sulfate levels  greatly  exceed predicted
 levels based upon ambient  chloride levels;  an average concentration  of
830 mg/1 was observed
                                     6-56

compared with a predicted concentration of 6.5 mg/1.  The elevated
sulfate levels are probably due to the dissolution of sulfate-bearing
minerals.

Fluoride levels in Wells LF-1, LF-5, LF-6, and PTW were  similar,
generally ranging from 0.37 to 0.59 mg/1; however, Well  LF-5 had a peak
(1.13 mg/1) in November 1981.  Wells UF-2 and DF averaged 1.05 and 1.01
mg/1, respectively, with a peak of 1.61 mg/1 observed in July 1981 in
Well DF.  Well LF-4 exhibited fluoride levels greater than all other
wells ranging from 1.89 to 2.32 mg/1.  Florida Class G-II fluoride water
quality standards were exceeded in 14 percent of samples from Well DF
and in all of the samples from Well LF-4.

Ionic content (including calcium, magnesium, sodium, potassium,
chloride, and strontium) was much higher in Well DF; however, Well LF-4
in October 1981 had higher sodium and chloride levels than all wells
except DF.

Nutrients
Inorganic nitrogen levels were relatively constant in all stations, with
the exception of a slight nitrate-nitrite peak observed  in Well DF.  In
March 1982, nitrate levels were observed to reach a maximum concentra-
tion of 0.19 mg/1 in Well DF; otherwise, during the study period,
nitrate levels remained below 0.06 mg/1.  Observed levels were
approximately two orders of magnitude below the established criterion
for Class G-II ground waters in Florida (10 mgN/1).  Excluding
Well UF-2, ammonia levels were also quite low, averaging less than
0.20 mg/1.  No violation of the Florida Class G-II nitrate standard
(10 mgN/1) was observed.

Total phosphate levels were also similar in all stations; however, a
peak was observed in Well LF-5 in March 1982.  Levels generally ranged
                                       6-59

-------
from 0 to  1.6 mg/1; however,  the  LF-5  peak reached  2.9  mg/1.
Or tho phosphate  levels  ranged  from 0  to 0.9 mg/1  in  all  wells;  no
correlation with  total  phosphate  was observed.

Alkalinity and  pH
Alkalinity was  generally of the bicarbonate form in all wells  except
UF-2 ; however,  some carbonate  alkalinity  was  also observed  indicating
some pH values  of 8.3 or greater.  Well UF-2  showed basic conditions
(pH = 11.1 to 11.9) and, subsequently,  alkalinity was predominantly
carbonate  in form, ranging from 78.1 to 155.6 mg/1  as CaCO,.   These
levels are unusually high and may be indicative  of  subsurface
contamination.  Aqueous solutions in contact  with calcite and  in  equili-
brium with typical levels of gaseous CO-  observed in subsurface  soils
(10~2 to 10~3 atm) have pH levels of 8.4  or less (Stumm and
Morgan, 1981).  Data from all other  stations  generally  conform to this
model for the Floridan Aquifer.   Wells  LF-1 and  DF  had  the  least  alka-
linity and were also the deepest  wells.   Total alkalinity averaged
78 mg/1 as CaCO, in Well LF-1 and 70 mg/1  as  CaCOj  in DF; elevated
levels of alkalinity were observed in  both wells in July 1981  (141 and
152 mg/1 as CaCOg, respectively).  Alkalinity in Wells  L^-S, LF-6 and
PTW were observed at similar levels which ranged from 62 to 245 mg/1 as
CaC03.  Well LF-4 had the highest levels  of total alkalinity which
averaged 212 mg/1 as
Excluding Well UF-2, carbonate alkalinity was detected most  often  in
Well PTW where pH values were never below 8.3 (8.3  to 9.5).  Well  LF-1
also had high pH values which averaged 8.5.  Most other  wells  had  pH
values between 8.0 and 8.5, except  for Well  DF  which had values  ranging
from 7.0 to 8.1.  Violations of  federal  secondary water  quality  pH
standards (6.5-8.5) were observed in Wells LF-1  (6/9 samples), PTW (6/9
samples), and UF-2 (11/11 samples).
                                       6-60

-------
Water Quality Aquifer Testing
Several airlift pump tests were conducted during  late  1975  on Wells OF,
LF-3, UF-2, UF-3, and SA-14.  Water samples were  collected  at various
depths during the pumping; water quality data  are  presented in
Table 6.1.4-6.  A comparison of parameters sampled during both the
monthly sampling and the Dump test sampling is  presented  in the
following section.

In the pump test sampling of the shallow aquifer  well  (SA-14), conduct-
ivity, bicarbonate alkalinity (CaC03),  TDS (residue),  nitrite (NC^),
sulfate (S0^)f  and fluoride were all  higher than  the ranges recorded
in the monthly  sampling.  Ammonia  (NHj), nitrate  (NC^) and  total
phosphate all fell within the monthly ranges,  whereas  silica (Si02>
       •
fell below them.

In the secondary artesian well  (UF-3),  only nitrate and nitrite was
above the ranges of the monthly sampling.  Total  phosphate  and sulfate
were at the upper limits of the monthly ranges, but silica  fell below
the range.  All other parameters duplicated were  within the ranges  of
the monthly sampling.

Of the samples  taken from the deep Floridan wells, alkalinity, nitrite,
total phosphate, and silica all fell  within the ranges, although silica
was near the higher end of the  range  on two occasions.  Conductivity,
total dissolved solids, sulfate, and  fluoride  all fell below the ranges.
Nitrate was above the range on  all 3  occasions, and ammonia was above
the range on 2 of the 3 days.

The DF well was also sampled at selected depths during October of 1975,
but ,only five parameters were tested.   TDS, total hardness, sulfate and
chloride concentrations all increased slightly as the  depth increased,
and then increased significantly at the lowest two depths.   Sodium
concentration also increased as depth increased,  but not  as
significantly.
                                       6-61

-------
 The  Florida Deoartraent of Natural Resources has published average
 concentrations of TDS, sulfate,  chloride and fluoride in the lower
 Floridan Aquifer (RI 83).  Concentrations of chloride and fluoride from
 the  lowermost  water sample (1,650 feet)  in the DP well agree with the
 results  of the report.  The concentration of TDS (2,792 pom) was about
 five  times higher than maximum concentration (500 mg/1) listed in the
 text,  and  sulfate (1,590 ppm)  was about  15 times the concentration of
 100 mg/1  reported in the text.

 6.1.4.3   SUMMARY
 A  total  of 18  wells  ranging in depth  from 25 to 66 feet were used to
 monitor  the  surficial  aquifer.  These  wells were sampled monthly for
 14 parameters;  7 of  the  wells  were sampled once for an additional
 7 parameters.   As expected,  a  close relationship between TDS and
 conductivity was  observed;  these parameters in turn were apparently
 dictated to a  large  extent  by  the localized presence or absence of
 carbonaceous material  within the surficial aquifer.  Conductivity had a
 low measurement  of 17  umhos/cm and a high reading of 570 uhmos/cm,
 whereas TDS (residue)  ranged between 2 and 501  ppm.  Tn general, the
 average concentrations of TDS  and conductivity on Complex II were about
 twice  those of  Complex I.   Levels of pH  were somewhat low relative to
 ambient alkalinities and  may reflect organic acids leaching  from
 detrital material in surface soil horizons.  Within the wells,  pH ranged
 from 4.9 to 8.5.  Sulfate levels ranged  from 1  to 123 mg/1.   The average
 sulfate  levels  on Complex II-East and  Complex I were about  three times
 greater  than those on  Complex  II-West.   No violations of fluoride were
 observed with  all values  less  than 1.16  mg/1.

 Nutrient sampling included  ammonia, nitrate,  nitrite, total  phosphorus,
 and orthophosphate.  In  general,  average nitrate and nitrite values  were
 low.  Ammonia  levels ranged  from 0.05  to 0.5 mg/1,  with the  majority of
 high values occurring on  Complex II-East.   Average TP and orthophosphate
 concentrations  were  relatively high with ranges from 0 to 7.7 mg/1  and
0 to 7.6 mg/1,  respectively.
                                        6-62

-------
A total of 4 wells ranging in depth from 360  to 418  feet were  used  to
monitor the secondary artesian aquifer.  These wells were  sampled
monthly for the same parameters as those in the surficlal  aquifer.
Conductivity had a low measurement of 200 uhmos/cm and  a high  reading of
660 uhmos/cm, whereas TDS ranged between 58 and 517  ppm.   The  average
values were about two to three times larger than  the surficial aquifer
averages.  Inorganic nitrogenous species generally were low.   Orthophos-
phate and total phosphorus were lower than the surficial aquifer, with
ranges from 0.0 to 0.8 ppm and 0.0 to 1.3 ppm, respectively.
Alkalinities reflected the calcareous matrix  of the  secondary  artesian
aquifer with a bicarbonate alkalinity range between  146.6  and  341.3 ppm.
All samples in three of the four wells exceeded the  1.6 mg/1 fluoride
ground water criteria.

A total of 7 wells, ranging in depth from 433 to  1,702  feet, were used
to monitor the Floridan Aquifer.  These wells were sampled monthly  for
the same parameters as those In the surfical  aquifer.   pH  in the wells
ranged between 7.0 and 9.5, except in Well UF-2 (11.1 to 11.9), which is
apparently influenced by subsurface contamination.   Conductivities  were
typically moderate, averaging less than 550 umhos/cm with  the  exception
of Wells UF-2 and DF; similarly, average TDS  levels  (excluding Wells
UF-2 and DF) ranged between 202 and 413 mg/1. With respect to other
wells in the Floridan Aquifer group, Well DF  was  unique chemically, and
apparently is influenced by dissolution of sulfate-bearing minerals;
conductivity, TDS and sulfate levels were all approximately 3  to 10
times in excess of observed values in the other wells.  Sulfate levels
were less than 100 mg/1 in all wells, except  Well DF which had values
between 400 and 1,600 mg/1.  Nutrients were generally low  and  no
violations of Florida Class G-II criteria of  10 mgN/1 were observed for
nitrate.  TP and orthophosphate were generally less  than 1.6 mg/1 and
0.9 mg/1, respectively.

Alkalinity was generally of the bicarbonate form  in  all wells  except
UF-2.  The two deepest wells, LF-1 and DF, had the least alkalinity.
                                      6-63

-------
 Carbonate  alkalinity was detected most often in Well PTW.  Violations of
 federal  secondary water quality standards for pH were observed in Wells
 LF-1  (6  of 9  samples),  PTW (6 of 9 samples), and UF-2 (11 of 11
 samples).   Fluoride  levels were similar in four of the wells with values
 less  than  0.6 mg/1.   The Florida Class G-II fluoride criteria was
 exceeded,  however,  in one of  the Well  DF samples and in all of Well  LF-4
 samples.

 The mean concentrations  of the ground  water parameters measured in well
 PTW were compared to  the  Florida Class III surface  water  standards to
 evaluate the  effects  of  deep  well  make-up on mine  discharge water
meeting Class III standards.   The  comparison indicated that all para-
meters measured were  below the  standards  except  pH,  which had a mean
value of 8.7  (which is a  0.2  units  above  the criteria).   This pH in
make-up water will buffer  the  recirculation water.   Since the streamflow
water quality is generally  acidic  and  often  below  the  minimum standard
of 6.0, mine discharge from the  more buffered  recirculation waters will
generally improve the acidic conditions  in  the  receiving  streams.

Effective January 1,  1986,  CF modified its  groundwater monitoring
 program after generating  a  10-year data base.   In  this revised  program,
groundwater levels are being  recorded  continuously  at  10  monitoring
wells.  In addition, groundwater quality  information  is being generated
 from seven monitoring wells.

7.1.L  REGIONAL DESCRIPTION—QUANTITY
The CF Industries Hardee Phosphate Complex  II  is  located  in  the  west-
central portion of the Peace River Basin as  shown  in  Figure  7.1-1.   The
site is drained primarily by two tributaries of the Peace  River:  Payne
Creek and Horse Creek.

The Peace River Basin drains portions of Polk, Highlands,  Hardee,
Manatee, Sarasota, DeSoto, and Charlotte Counties.  The  total  drainage
area at the mouth of the Peace River is approximately 2,300  square
miles; total main channel length is approximately 105 miles  (Florida
Board of Conservation, Division of Water Resources  and Conservation,
1966).  Other major tributaries of the Peace River  include Peace,
Charlie, Joshua, and Prairie Creeks.

Terrain in the northern portion of the basin is generally  above  100  feet
MSL and decreases southward toward Charlotte Harbor.  The  northern  Peace
River Basin lies in the Polk Uplands which  are characterized by  marshy
flatlands and rolling hills.  The Southern  Peace  River basin lies
                                d
primarily in the DeSoto Plain which is characterized  by  many lakes  and
large areas of poorly drained swampland.  The  DeSoto  Plain is  flat,
having an incline of about 15 to 25 feet in 40 miles. The depressional
areas within the basin are an important factor in  recharging the
shallow aquifer and in retarding runoff to  provide  natural flood control
and a source of baseflow during dry periods.

The USGS has maintained numerous stream gauging stations on  the  Peace
River and its tributaries.  Pertinent data  from those stations in the
vicinity of the CF site are summarized in Table 7.1.1-1.   Station
locations are shown in Figure 7.1-1.

Average  annual  rainfall  in Hardee County is 54 inches (Hughes et al.,
1971); however, monthly  and annual variation can be significant.
Approximately 60  percent  of the total annual average precipitation
occurs during the months  of June, July,  August, and September.  During
these months, intense  thunderstorms of relatively short duration
saturate  the surface  soils and raise the shallow aquifer.  As a result,
stream discharges  may  rapidly  increase and local flooding often occurs.
During the remainder  of  the year, rains  are generally of the gentle
frontal type.  During  this  drier  period,  the water table normally drops
and some  streams  become dry.   On  an annual basis, EPA (1979) character-
izes the  area as  having an  average  rainfall of about 55 inches, an
average evapo-transpiration of 39 inches,  an average total surface
runoff of 15 inches, and  an aquifer recharge of between 1/2 and
5 inches.

7.1.2  SITE-SPECIFIC DESCRIPTION—QUANTITY
7.1.2.1   BASIN DESCRIPTIONS
The CF property consists  of two complexes,  Complexes I  and II.
Complex I is the northern  tract of  property and is currently being mined
by CF;  Complex II is the  southern portion  of the property which is
proposed  for mining and is  the  study  area  for this EIS.   Complex I is
drained primarily  by Payne  Creek,  and Hickey Branch which is one of its
tributaries.  Complex  II  is  primarily drained by Horse  Creek,  Payne
Creek and, to a much lesser extent,  Troublesome Creek.   Drainage areas
on Complex II are  shown in  Figure 7.1-2.

Portions  of ten drainage  basins are  present on the Hardee Phosphate
Complex II site.  Six  of  these  basins (Horse Creek,  Brushy Creek,
Shirttail Branch, Doe  Branch,  Plunder Branch,  and Coons  Bay Branch)  have
defined stream or channel  systems on  the site.   Lettis  Creek,  Gum Swamp
Branch,  Hog Branch, and Troublesome Creek  have poorly defined  on-site
drainages.

-------
The property  is  located  on  a  regional  drainage divide with the western
half of  the property  draining south and the eastern half draining to the
north and  then east.

Other than the two minor  drainages  (Hog Branch and Gum Swamp Branch),
Horse Creek is the only  drainage  system which  does not begin with a
headwater  area on the  property.   Horse Creek is an intermittently
flowing  stream within  the property  which has an average annual flow of
over 5 cfs at the property  exit.  The  headwater region of Horse Creek
lies about 4 river miles  above  the  property.

In addition to Horse Creek, the other  on-site  drainages flowing to the
south are Brushy Creek, Lettis  Creek,  and Troublesome Creek.  Horse
Creek and Troublesome Creek are direct tributaries of the Peace River,
joining  the Peace River at  approximately 40 and 9  river miles down-
stream of the  site,  respectively.   Brushy Creek is a direct tributary of
Horse Creek,  which it joins south of Ona,  about 11 river miles down-
stream of the  site.   Lettis Creek is a minor tributary of Brushy Creek,
which it joins about 3 miles  south  of  the property.

The four streams  flowing to the south  vary considerably and do not
exhibit uniform characteristics.  Brushy Creek basin consists primarily
of two main headwater areas,  one  of which is called Mitchell Hammock,
draining into  a relatively  large  floodplain swamp  conveyance system
extending off  the site.  Although Lettis and Troublesome Creeks have a
portion of their  headwater  drainage area on the CF site, neither of
these creeks has  a defined  channel  existing on the site.

Plunder  Branch, Shirttail Branch, Coons Bay Branch,  Doe Branch and Gum
Swamp Branch  flow north  to  Payne  Creek, which empties into the Peace
River about 8 river miles downstream  of the site.   Each of these
drainages  joins  Payne Creek within approximately  I mile  of  the  property
boundary.

 Drainage profiles for the  five drainages flowing  into Payne Creek are
 similar.  Each drainage begins in  an  elevated  plateau region characterized
                                      7-6

-------
by relatively flat elevations and  large wetland  complexes,  generally
marshes with intermixed oak hammock.  Each  of  these  headwater wetlands
has a high natural lip or barrier  which retains  water  in the wetland.
The headwater wetlands complexes are generally marshes,  most often
dominated by maidencane.  Vegetation along  the well-defined channels and
the lower reaches of the systems usually  consists  of oak hammock, maple/
tupelo swamp, pop ash swamp, or bottomland  hardwoods forest.

Immediately adjacent to the headwater wetlands,  the  downstream segment
is represented largely by incised  stream  channels  or by  narrow distinct
floodplains serving as conveyances for  transporting  waters  from the
plateau wetland headwaters.  While some of  the headwater wetlands likely
retain water throughout the year,  these conveyance systems  flow only
seasonally to ephemerally and are  usually dry  for  portions  of the year.

The lowest portion of each stream,  near the northern property boundary,
could generally be characterized as an  area of reduced velocity and
lower stream gradient in which water begins to spread out over a broad
floodplain depositing materials carried in  the flowing waters.  Through-
out the year, these lower reaches  generally contain  isolated pools of
water along the primary stream channel.

The tenth drainage basin, namely Hog Branch, drains  to  the  east by
overland flow across upland regions.  No  wetlands  nor defined stream
channels are associated with the onsite drainage system.

7.1.2.2 DATA COLLECTION
Previous Studies
CF Industries has maintained an extensive monitoring network of stream
level recorders and rainfall stations on  the property since July 1975,
as shown in Figure 7.1-3.  -Continuous recorders  are  located at
Stations WQ-1, WQ-2, WQ-3, WQ-4, and WQ-7,  and current measurements are
generally taken every six months to calibrate  stage/discharge curves for
each station.  These level recordings! have  been  reduced  by  CF into
average daily discharges.  A staff gauge  has been  read  since July 1979
on Doe Branch at WQ-8 at a minimum of once  per week  in  the  dry periods
and twice per week in the wet periods.  These  staff  heights have also
been reduced by CF into instantaneous discharges.  A summary of the

annual range of discharges  recorded  on Rickey Branch,  Gum Swamp Branch,
Doe Branch, and Payne Creek is  presented  in Table 7.1.2-1.  Continuous
rainfall recordings have been collected at  eight  stations since July
1975 and have been reduced  and  tabulated  by CF Industries.  The total
rainfall which occurred each year on  the  CF site  is  shown in the right
column of Table 7.1.2-1.

EIS Monitoring
The monitoring period for  the EIS data collection effort was from July
1981 through June 1982 and  includes  data  collected by  both CF Industries
and ESE.  The surface water level recorders, staff gauge readings, and
continuous rainfall recordings  as described in the preceding section
(Previous Studies) were maintained  from July 1981 through June 1982 and
were reduced by CF Industries.  ESE measured stream  flows monthly at
Stations WQ-5, WQ-8, WQ-9,  WQ-10, WQ-11,  and WQ-12 from July 1981
through September 1981.  After  meetings with EPA  in  late September 1981,
the monitoring program was  revised  and additional flow measurements were
taken in September 1981 at  Stations WQ-1  through  WQ-4,  WQ-7, WQ-13, and
WQ-14.  Stations WQ-9 and WQ-12 were  dropped from the  program after
September 1981.  These changes  resulted in  monthly stream measurements
taken from October 1981 through June  1982 at Stations  WQ-1 through WQ-5,
WQ-7, WQ-8, WQ-10, WQ-11, WQ-13, and  WQ-14.

ESE installed a Stevens Type-A  level  recorder on  Horse  Creek at
Station WQ-11 in July 1981  and  maintained this gauge  through June 1982.
The monthly flows measured  at this  station  were used  to develop a
stage/discharge curve.  This stage/discharge curve was  used to reduce
the level recordings into average daily flows.

7.1.2.3  DATA ASSESSMENT
In order to estimate long-term  average daily discharges for the ungauged
streams on the property, a  correlation was  needed between a long-term
gauging station and streams on  the  property.  As  stated in the CF DRI
(1976), the Payne Creek Basin is hydrologically similar to the upstream
                                 7-9

portion of the Little Manatee River Basin.  Therefore,  the USGS gauging
station 02300100 on the Little Manatee River  at  Fort  Lonesome  was
chosen.  This gauge has been operating since  September  1963 and has  a
drainage area of 38.4 square miles (USGS,  1978).   The on-site  stations
for correlation were limited to WQ-4, Gum  Swamp  Branch,  and WQ-8,  Doe
Branch, since the other gauges are influenced by discharge from existing
mining operations.  Station WQ-4 has a drainage  area  of 10.1 square
miles (CF Mining Corporation, 1976) and WQ-8  has a drainage area of  8.0
square miles.

The correlation between Station WQ-4 and the  USGS station was  determined
by performing a regression analysis between the  average monthly flows at
each of these stations from January 1976 through September 1981.  The
   *
correlation coefficient (r) was determined to be 0.72.   The regression
analysis between the average monthly flows at WQ-8 and  the USGS station
was performed for the period of overlapping record,  i.e.,  February 1979
through September 1981.  The correlation coefficient  (r) for this
analysis was 0.76.  The results of these regression  analyses showed  that
the average 17-year flow rate was 0.35 cfs per square mile (cfsm)  for
the CF property.

For each of the other surface water stations  on  Complex II, total
drainage basins were delineated on 2-foot  interval topographic maps
provided by CF Industries.  The results are depicted  in Figure 7.1-2.
The size of the basins and the percent of  each basin  in the mine
property were planimetered from these maps.   The average flows at  each
station on Complex II were calculated by multiplying  the drainage  area
of each basin by the 17-year flow rate (0.35  cfsm) as determined in  the
previously described regression analyses.  The basin  areas and average
flows are presented in Table 7.1.2-2.

The results of the on-site rainfall monitoring are presented as monthly
totals in Table 7.1.2-3.  By comparing the site  average rainfall to  the
NOAA gauge located in Wauchula, the site rainfall during the monitoring
                                      7-11

 year  is  4 inches above "normal" (the 30-year average precipitation).
 According to SWFWMD (1981)  classification, the monitoring year would be
 classified  as  a normal year.   Even though the annual rainfall for the
 site  is  classified as  normal, the monthly precipitation totals varied
 widely  from monthly normals.   The months of July, September, October,
 and January had rainfall deficits of more than 1 inch, the  largest being
 over  3  inches  in September.   These deficits were balanced primarily by
 rainfall  in excess of  normals by +2.74, +3.05, +5.23, and +4.34 inches
 in August,  March,  May,  and  June.  The result of the high monthly
 rainfall  in August was a steep increase in the stream flows and peaks
 occurring in September 1981.   Likewise, the surplus rain in May and June
 caused  local flooding  on several of the streams.  The average daily
 discharges  at  Stations  WQ-3,  WQ-4,  WQ-7 and WQ-11 are presented in
 Figures 7.1-4  through  7.1-7.   The results of the monthly flow
 measurements are presented  in Table 7.1.2-4.

 The results  of  the EIS  flow measurements and CF monitoring program on
 the Complex  II  tract yielded  the following information:
      I.  Stations  WQ-9  and WQ-12 were dry or ponded during July and
         August  sampling  and  were flowing in September as a result of
         about  3 inches  of  rainfall during the six days  prior to
         sampling.
      2.   In  general, the monthly measurements at WQ-5, WQ-8, and WQ-10
         showed  similar  flow  patterns,  i.e.,  dry or ponded during the
         monthly sampling for the entire year except during heavy
         rainfall  periods in  August,  September,  and June.
      3.  The reduction of the level recording at Station WQ-11 showed
         that  Horse Creek was dry or  ponded during December and January
         and during parts of  November,  February, and May.  During the
         remaining months,  the stream had flowing conditions.

The monitoring  on  the  Complex I tract indicated that, in general, all
 the streams  on  the existing mine site were flowing during the  sampling
 period.

 7.1.3  REGIONAL DESCRIPTION—QUALITY
 The CF property is drained primarily by Horse Creek and tributaries of
 Payne Creek,  which drain to the Peace River.  The following section
 presents a brief discussion of the regional water quality of Horse Creek
 and the Peace River.

 7.1.3.1  HORSE CREEK
 The CF properties  are located near the headwaters of Horse Creek.  Water
 quality data  have  been collected in this reach of the creek by CF at
 Station WQ-6.   Downstream,  water quality data have been collected for
 Mississippi Chemical  Corporation (MCC)  at Station MCC-2 (see
 Figure 7.1-8).   Further downstream near Arcadia, extensive water quality
 data have  been  collected by USGS.

 A  comparative  summary of water quality changes along the length of Horse
 Creek is presented  in Table 7.1.3-1.   Although collected at different
 times  and  during different  flow conditions, these data are useful for
 the  assessment  of general  similarities,  differences,  and changes within
 the  basin.  In  general,  dissolved  material in the water increases from
 upstream to downstream,  as  is  observed  for alkalinity, conductivity,  and
 total  phosphate.  Although  some minor differences are observed, the two
 upstream stations have  similar water  quality.   These  stations  differ
 significantly  from  the  downstream  station at Arcadia.

 USGS  has maintained a water quality station on Horse  Creek near Arcadia
 since  1962.  The drainage area at  this  station is approximately
 212  square miles.   The  water  quality observations made at this site  are
 summarized in Table 7.1.3-2.   For  comparative  purposes,  this  table  also
 reflects applicable Florida Class  III water quality  standards.

The  following observations  were made  from the  water  quality summary for
Horse Creek near Arcadia.   No  mean  concentrations violate  Florida
Class III standards.  However,  violations  occur  for  the extreme values
of alkalinity,  conductivity, dissolved oxygen  (DO), pH,  and mercury.
Since alkalinity is generally  low  (38 mg/1 as  CaCC^),  even the  low  to
                              7-20

 moderate  color levels (125 PCU) produce acidic conditions.  Nitrogen
 levels are low;  however, nitrate-nitrite are moderate to high,
 indicating fertilizer input from leached ground water or runoff.  Total
 phosphate is high,  averaging 1.37 mg/1.  Waters are generally well
 oxygenated,  with DO average 7.7 mg/1 and biological oxygen demand (BOD)
 average 0.9  mg/1.   Dissolved ions are moderate.  Specific conductivity
 averaged  251 umhos/cm,  indicating a TDS concentration of 140 to
 225 mg/1.

 7.1.3.2  PEACE RIVER
 Payne  Creek  flows  into  the Peace River downstream of its confluence with
 Little Payne Creek.   No  long-term water quality stations are located on
 Payne  Creek.   Over  the  past 30  years, water quality data in the Peace
 River  have been  collected  by USGS at Zolfo Springs, south of the Payne
 Creek  inflow.  Table 7.1.3-3 summarizes the water quality gathered at
 this site  from August 1951  to May 1981.

 The following  observations  were made from the water quality summary at
 this USGS station.   Waters  in the Peace River at  Zolfo Springs have low
 to moderate  color levels,  high  conductivity,  and  high phosphate levels.
Color  averages 65 PCUs,  with moderate alkalinity  (52 mg/1 as CaC03).
 pH averaged  slightly in  the  basic  range (7.16).   Dissolved solids are
high at the  station.  Specific  conductance  averaged 388  umhos/cm, indi-
cating  a Total Dissolved Solids concentration of  210 to  350 mg/1.
Nitrogen is  low  in  the river; however,  nitrate-nitrite is high
 (1.13  mg/1),  indicating  fertilizer  input  from ground water or  runoff.
Total  phosphate  is  high, averaging  7.17 mg/1.   Dissolved oxygen was
observed at moderate  levels, averaging  6.9  mg/1,  and BOD was generally
 low, averaging 1.4 mg/1.

Water  quality  has also been  monitored by  USGS on  the Peace River near
Arcadia, at a  station located about 33  miles  downstream  of the Zolfo
Springs station.   Water  quality at  this station is  similar to  that
observed at Zolfo Springs.   These  similarities may  be  seen in  the
comparison of  the two stations  which appears  in Table  7.1.3-4.

         twice during 1981.

Continuous measurements of temperature, dissolved oxygen,  pH,  and
conductivity are made at  Stations WQ-1, WQ-2, WQ-3,  and WQ-7.

Water  quality data  are  reported  quarterly to Hardee  County,  FDER and
EPA.

EIS  Monitoring
ESE  initiated water  quality  sampling  efforts on the  CF property in July
1981,  and conducted  a l-year monitoring  program that  covered the period
July 1981 through June  1982.   ESE visited the CF property in June 1981
and  observed that,  except for  Horse Creek,  none of the other  five
                                   7-27

-------
 streams on the South Pasture mine site were flowing at the property
 boundaries.  Therefore, the period of July 1981 through June 1982 is
 representative of a complete wet and dry season annual cycle.
 Streamflow hydrographs showing water quality sampling dates are
 presented in Figures 7.1-4 through 7.1-7 for Stations WQ-3, WQ-4, WQ-7,
 and WQ-11.

 ESE performed the following sampling and analyses for the water year
 July 1981 through June  1982 (see Table 7.1.4-1  for referenced parameter
 listings  and  Figure  7.1-3  for  station locations).

 7.1.4.2   DATA ASSESSMENT
Water quality data gathered  during the EIS  and  during  previous  studies
have been summarized by statistical  analyses using the  raw data values.
The raw water quality data  for the EIS monitoring  are  included  in
Appendix B.  The raw data  for  sampling conducted  by  CF  Industries,
Mississippi Chemical Corporation (MCC), and Farmland Industries are
extensive and are, therefore,  not included  in this report.

Horse Creek Basin
Three streams are discussed  in Horse Creek  Basin,  including  Horse Creek
(WQ-ll), Brushy Creek (WQ-9), and Lettis Creek (no  sampling  on CF
property).  Water quality data on the CF site for Horse  and  Brushy
Creeks include three months  (July through September)  during  1981.
Historical data near the property on Horse  Creek were  collected by CF
Industries (WQ-6) and by Mississippi Chemical Company  (MCC-2).
Historical data on Brushy Creek were collected at MCC-10 and Farmland
Industries Station S-2 downstream of the site.  Data  for Lettis Creek
were collected during previous studies of MCC's proposed mine  at Station
MCC-12 located about 3 miles south of Complex II (see  Figure 7.1-8 for
location of stations).

Horse Creek traverses the western end of Complex II,  with 9.5  percent of
Lts basin upstream of Station WQ-ll draining CF property.  The  water
quality sampling station on Horse Creek (WQ-ll) was  located  about  one-
half mile north of CF's southern boundary in an open  area.   The channel
at this location was generally broad and shallow.  The stream bottom  was
primarily sand with some organic muck in the pooled  areas.   Brushy Creek
drains 4.2 square miles at Station WQ-9, with 98 percent of  that
drainage on CF property.  The sampling station on  Brushy Creek  was
located on the upstream side of the dirt road that  runs  along  CF's south
property line.  The ditch-like channel was  in a open  area.   The channel
was shallow and heavily vegetated.  Lettis  Creek does  not traverse CF
property, but has a small portion of its drainage  basin  on the  property
(but no defined channel exiting the property).  Therefore, no  sampling
was conducted on this creek.

Land use in the basin consists primarily of rangeland, marsh and flat-
woods, and forested swamps bordering the streams.

Water quality data collected for the basin  during  the  EIS monitoring  and
previous studies are summarized in Tables 7.1.4-2  through 7.1.4-5.

General Parameters
Waters in the basin can  generally  be  considered to be colored waters of
low turbidity.  Color  levels were  highest  in Brushy Creek (383 PCU), and
lowest in Lettis Creek (275 PCU).   These  levels can be considered
typical for Florida streams traversing  the swampland areas.   Color
reflects the effects of  contact  with  swamplands where decaying organic
vegetation forms humic and  fulvic  acids.   These materials make up most
of the color in Florida  waters,  and affect pH,  productivity,  and metal
transport.  Suspended solids were  lowest  in Horse Creek during the EIS
monitoring «5 mg/1), but historically,  the data appeared variable with
a maximum of 1,437 mg/l.  Brushy Creek  experienced a buildup  of
suspended matter during  ponded conditions.  Turbidity was generally less
than three NTUs for all  the streams,  but  historically, Horse  Creek
experienced higher turbidities,  reaching  a maximum of 52 NTUs.  Lack of
turbulence and slow moving  conditions are  probably the reasons for
little suspended material in the streams.

Dissolved Ions
Total Dissolved Solids (TDS) were  highest  in Lettis Creek, and lowest in
Brushy Creek.  Specific  conductance,  historically, averages  115 umhos/cm
for Lettis Creek, indicating a TDS  level  of 85  to 140 mg/1.   Brushy
Creek averages 66 umhos/cm  indicating a TDS level of 36 to 59 mg/1.

Alkalinity and pH
Alkalinity is highest in Lettis  Creek (51.63 mg/1 as CaCC^).   EIS
monitoring indicated Horse  Creek had  the  lowest alkalinity (5 mg/1 as
      , but historically levels  were  slightly higher (11.6 mg/l as
      .  Alkalinity in the  streams  was often below the minimum
standard for Florida Class  III waters; historically,  Horse Creek was
below the standard in 117 of the 145  samplings.  Low alkalinity suggests
low buffering capacity in the stream  and,  with  acidic input,  acidic
conditions could be expected.  Generally,  acidic conditions  are found in
the streams;  Brushy Creek is the most acidic with a mean pH of 5.17,
while Lettis Creek is the least  acidic with a pH of 6.22.  The same
order is observed with organic color, and  these acids may be
determinative of pH in the  streams.
                                  7-36

-------
Nutrients
Nitrogen was lowest in Lettis Creek  and  highest  in Brushy  Creek.   Lettis
Creek had an organic nitrogen concentration of  1.51  mg/1,  whereas
concentrations in Brushy Creek  averaged  2.79 mg/1.   Values of organic
nitrogen were higher in Brushy  Creek during ponded  conditions indicating
the buildup of organic matter when flushing is  reduced.   Inorganic
nitrogen (ammonia, nitrate, nitrite) was observed  at lower levels in
Horse Creek.

Total phosphorus levels were highest in  Brushy  Creek (0.708 mg/1) and
lowest in Lettis Creek (0.30 mg/1).  The form of  this phosphate was
primarily ortho-phosphate which represented as  much  as 85  percent of the
total.  These conditions illustrate  the  low productivity levels in the
stream.  In a productive system,  inorganic phosphate is  taken up rapidly
and converted to an organic form.  These organic  forms are generally
less accessible to organisms and  therefore build  up  and  become the
predominant form in the water body.

DO/BOD
Both DO and BOD were low in the streams.  DO averaged less than 3 mg/1
in all the streams, whereas potential  DO saturation  values ranged from 7
to 11 mg/1.  Low DO values can  be expected when BOD  is high; however,
BOD averaged less than 4 mg/1 for all  the streams.

The possible mechanisms that can  cause the loss  or consumption of oxygen
are:
     I.  Oxidation of organic and inorganic substances,
     2.  Respiration by aquatic organisms (both  plant and  animal),
     3.  Oxygen diffusion to the  atmosphere,
     4.  Nitrification of ammonia, and
     5.  Iron organic matter interactions in colored waters.

Microbiology
Fecal coliform counts were highest in  Brushy Creek (687/100 ml),
possibly due to ponded conditions, and were lowest (historically) in
Horse Creek (212/100 ml).  These  conditions probably reflect impact from
cattle and rangeland runoff.

Payne  Creek Basin:   Tributaries Draining Complex II
Water  quality samples  were  collected from four tributaries draining
Complex  II  north  to Payne Creek.   These tributaries include Shirttail
Creek  (WQ-10),  Doe  Branch (WQ-8),  Plunder Branch (WQ-5), and Coons Bay
Branch (WQ-12).   Samples  were  collected monthly at Station WQ-5,
Station  WQ-8,  and Station WQ-10 during the period July 1981 to June
1982,  and  from July 1981  through  September 1981 at Station WQ-12.
Historical  data collected by CF Industries at WQ-5 were also used to
assess water  quality.

Water  quality  data  on  these streams during the EIS monitoring are
summarized  in Tables 7.1.4-6 and  7.1.4-7.  Historical data at
Station  WQ-5  are  presented  in  Table 7.1.4-8.   These streams are
generally slow moving  and most samplings were collected from ponded
water.   All  streams were  observed  to have some movement in September
1981.  Flow was also observed  at  Stations WQ-5, 8,  and 10 during the
month  of June  1982.  Land use  in  the basin is primarily forested swamp,
rangeland,  flatwoods,  and marsh.   Drainage basin areas and estimated
average  flows  at  each  station  are  presented in Table 7.1.2-2.

The sampling  station on Plunder Branch (WQ-5) was a pooled area approxi-
mately 30 feet  upstream of  the culverts at SR 62.  This pooled area is
about  30-feet  across,  2-feet deep  and  densely wooded.   The samples were
collected where the  pool  drained  into  a small, poorly defined channel
which  was heavily vegetated.   The  sampling station  on Doe Branch (WQ-8)
was on the upstream side  of the culverts at SR 62.   The stream channel
at this  location  was open,  very broad  and shallow.   The stream bottom
was primarily  organic  muck.  The channel was  usually ponded and covered
with vegetation.  Shirttail Branch (WQ-10) was sampled about  one-half
mile south of SR  62 at CF's property boundary.  Samples were  collected
from a stream channel  which was moderately wooded with moderate under-
story.  The stream  channel  contained much wood debris.  Coons Bay Branch
(WQ-12)  sampling  location was  on the upstream side  of  the culvert at
SR 62.  The channel was poorly defined.

-------
General  Parameters
As  in  the Horse  Creek Basin,  organic color is an important part of the
water  chemistry  of  the streams  draining Complex II.  Coons Bay branch
had  the  highest  organic color levels, averaging 313 PCU, whereas Doe
Branch had  the lowest,  averaging 183 PCU.  Color appeared to be higher
during  flow conditions, indicating the effect of flushing in swamps.  In
contrast, suspended  matter  was  higher during ponded conditions.

Suspended solids were highest in Coons Bay Branch (111 mg/l) and lowest
in Shirttail  Branch  (9  mg/l).   Turbidity was highest in Doe Branch
(14.3  NTU)  and lowest in Shirttail Branch (3.06 NTU).  Methylene Blue
active substances and oil and grease were not detected in.any of the
streams  sampled  indicating  little impact from man.

Dissolved Ions
Specific conductance  measurements were highest in Coons Bay Branch
(450 umhos/cra) and lowest,  historically, in Plunder Branch (139 urnhos/
cm).  These  levels correspond to Total Dissolved Solids levels of 247 to
405 mg/l in Coons Bay Branch  and 76  to 125 mg/l in Plunder Branch.
Dissolved ions appeared to  have negative correlation with flow (i.e.,
dissolved ions were  low when  flow was high) probably due to less
influence by  ground water inflow.

Alkalinity  and pH
The balance of acidity  and  alkalinity determines the pH of waters.   In
the four streams considered,  high  organic acid inflow would infer acidic
conditions.   This is  substantiated by pH measurements; historically,
Plunder Branch had the  highest  pH (6.66), and the measurements in Coons
Bay Branch  were  the  lowest  (5.23).   Alkalinity would be expected to
neutralize  some  of the  acid.  However,  when alkalinity is low, its
buffering may not be  substantial.

Plunder Branch had the  highest  alkalinity (69 mg/l  as CaCC^)  and
highest pH.    Shirttail  Branch had  the lowest  alkalinity (17 mg/l as
       and  the second  lowest  pH (5.90).
                                7-42

-------
Nutrients
Nitrogen levels were higher during  ponded conditions,  possibly reflect-
ing the buildup of organic matter when little  flushing  is  occurring.
Plunder Branch exhibited the lowest  total Kjeldahl  nitrogen (1.64 mg/1)
and Coons Bay Branch the highest (4.10 mg/1).

Nitrate-nitrite was highest in Doe  Branch (0.28 mg/1) and  may  indicate
fertilizer input.  Total phosphorus  was highest in  Plunder Branch
(1.29 mg/1) and lowest in Doe Branch (0.541 mg/1).  Total  phosphorus  was
primarily ortho-phosphate (50 to 70  percent),  however,  the proportion of
ortho-phosphate decreased during ponded conditions, indicating the
buildup of organic matter with little flushing.

DO/BOD
As in the Horse Creek Basin, both DO and BOD were low,  possibly indicat-
ing the effect of oxygen removal in  swamps and  little DO replacement.
All dissolved oxygen averages were  below 4 mg/1 while expected satura-
tion values might range from 7 to 11 mg/1.  BOD averaged 4 mg/1 and less
for all the streams.  Lower DO and  higher BOD  were  observed during
ponded conditions at some samplings.

Metals
Water quality standards violations  were observed  at all stations for
zinc, mercury, and iron (Coons Bay  Branch was  not sampled  for  metals).
In addition, violations of the cadmium and silver standard were observed
in Doe Branch and Plunder Branch.   Metals solubility  is affected by pH
and acidic conditions may be a factor in metals levels.  In addition,
the complex ing of metals with humic  and fulvic  acids  (chelation) will
affect dissolution and transport of metals.

Microbiology
Coliform levels were highest (historically) in Plunder  Branch
(349/100 ml) and lowest in Shirttail Branch (149/100  ml).   Coliform
counts probably reflect runoff from rangeland  and cattle grazing areas.
                                     7-43

-------
 Payne Creek Basin;  Tributaries Draining Complex i
 Tea water quality samples were collected during the period September
 1981 to June 1982 from five stations on tributaries draining Complex I.
 Tributaries include Rickey Branch (WQ-1 and 7), Gum Swamp Branch (WQ-4),
 and Payne Creek on the property (WQ-2 and 3).  These data, along with
 historical data obtained from CF are summarized in Tables 7.1.4-9
 through 7.1.4-16.   The existing Agrico mine located north of CF property
 discharges water to Payne Creek and Hickey Branch upstream of the CF
 sampling  stations  (see Figure 7.1-9).  All stations were flowing during
 monthly sampling except WQ-4  during October 1981.

 The  water  sampled  at  Station  WQ-1  is predominantly Agrico's mine
 discharge.   Samples were  collected on the  downstream side of four 18-
 inch  culverts which drained into a shallow,  sand bottom channel.  The
 area  was open and  moderately  vegetated.  The water sampled at
 Station WQ-7 is  a  combination  of CF's discharge from their  existing
 mine, Agrico's discharge,  and  about  5 square miles of  natural drainage.
                                      H
 Sampling stations  at WQ-2, WQ-3, and WQ-7  were  similar,  i.e., they  were
 well-defined sand  bottom  channels  through  moderately wooded areas.   It
 is important to  note that CF's Discharge Point  001 is  essentially
 Agrico's discharge with no discharge water added from  CF's  operations.
 All discharges from CF's  operations  are  from CF's  Discharge Point 002.

 The samples collected  at  WQ-2  and  WQ-3  are representative of Agrico's
 discharge and about 50 square  miles  of  natural  drainage.  Gum Swamp
 Branch has a drainage  basin of about  10 square  miles and  no point source
 discharges.  The stream channel at  the  sampling location  was well-
 defined with a sandy bottom.   The  station  was in a thickly  wooded area
 with moderate understory.  Average  daily flows  at  WQ-3, WQ-4, and WQ-7,
 along with water quality  sampling  dates  indicated  are  presented  in
 Figures 7.1-4 through  7.1-6 in the  surface  water quantity discussion.

 Land  use in the  basin  is  primarily flatwoods,  rangeland,  forested
wetlands, marsh, and disturbed areas (mined  land).

-------
General  Parameters
Color  levels in Payne Creek Basin are generally much lower Chan those in
Horse  Creek Basin.   Gum Swamp Branch had the highest color levels
(141 PCU)  and Mickey Branch upstream had the lowest (29 PCU).  Suspended
solids in  all screams averaged less than 15 mg/1, both historically and
in EIS monitoring.   Turbidity was generally less than 5 NTH at all
stations.

Dissolved  Ions
Specific conductance was  highest  in Hickey Branch (290 to 325 umhos/cm)
and lowest  in Gum Swamp Branch (158 to 179 umhos/cm).  These values
correspond  to total  dissolved solids levels of 159 to 361 mg/1 for
Hickey Branch and 87 to 161  mg/l  in Gum Swamp Branch.  Specific
conductance  was  somewhat  negatively correlated with flow.

Alkalinity  and  pH
Acidity  in  these  streams  is  determined by natural organic acid input and
alkalinity,  however,  Agrico's mine  discharges may have higher alkalinity
and may  produce more buffering in the streams.

Hickey Branch upstream  had  the highest alkalinity of the stations
sampled  (102  mg/1 as CaCG^j).   Gum Swamp Branch had the lowest (31  mg/1
as CaCO}).   These same  trends were  observed for pH;  Hickey Branch
reflected  the most basic  conditions (7.69)  while Gum Swamp Branch was
the only stream  to exhibit  predominantly acidic conditions (6.42).
These  trends  are  confirmed  historically.

Nutrients
Total  KjeldahL  nitrogen averaged  less than 1.2  mg/1  for all streams;
Hickey Branch downstream  had  the  highest levels (1.14 mg/l) and Payne
Creek  upstream  had the  lowest (0.60 mg/l).   Inorganic nitrogen,
(nitrate-nitrite, ammonia),  was high in comparison to most natural
Florida streams and  probably  reflects input from fertilizer.   Nitrate-
nitrites were highest in  Gum Swamp  Branch (0.923 mg/l)  and lowest  in
Hickey Branch upstream  (0.045 mg/l).

Total  phosphorus  was highest  in Payne Creek downstream (0.774 mg/l)  and
lowest in Hickey  Branch (0.340 mg/l), but historically,  all streams  had
                                  7-54

-------
much higher levels averaging more than 0.8 mg/l  in  the  past  six  years.
Total phosphorus concentrations were variable, historically  (i.e.,
Hickey Branch upstream ranged from 0.10 to 5.0 mg/l) which may reflect
mine discharge.  Ortho-phosphate was the  predominant  form of phosphorus
ranging from 50 to 90 percent.

Dissolved Oxygen/BOD
Dissolved oxygen was much higher in comparison to  levels  in  other
basins, possibly indicating less contact  with wetlands.  DO  was  highest
at the Payne Creek upstream station (7.9  mg/l) and  lowest  in Gum Swamp
Branch (6.2 mg/l).  BOD was less than 4 mg/l at  all stations, but was
lowest in Gum Swamp Branch (l.l mg/l).

Metals
Violations of water quality standards were observed for cadmium,
mercury, and zinc for all stations.  In addition,  violation  of  the iron
standard was observed in Gum Swamp Branch, reflecting  greater solubility
in acidic waters and complexing with organic acids.

Microbiology
Fecal coliform  counts were highest in Hickey Branch downstream
(648/lOOml) and lowest in Hickey Branch upstream (33/100ml).  The high
col iforra levels probably reflect runoff  from rangeland and  cattle
grazing areas.

Comparison of Upstream and Downstream Stations—Stations WQ-1 (upstream)
and WQ-7 (downstream) can be used  to detect changes in water quality in
Hickey Branch.  Waters downstream  appear  to have more organic color but
less suspended matter.  As might be expected  from this, pH and
alkalinity are  both  lower downstream as  a result of the color from
wetlands.  Nitrogen  levels are  comparable at both stations;  however,
nitrate-nitrite levels are higher  downstream  indicating some fertiliza-
tion in the drainage basin.  Total phosphorus  is also higher downstream
(WQ-1 « 0.340 mg/l; WQ-7 - 0.510 mg/l).   No  significant differences are
apparent in dissolved oxygen concentrations;  however,  BOD was slightly
higher upstream (3.5 mg/l).  Coliform  levels  were much higher
downstream.

                                     7-55

-------
 Two stations on Payne Creek (WQ-2, WQ-3) were also sampled at entrance
 and exit points of CF property.  Agrico discharge enters Payne Creek
 upstream of WQ-2 and Gum Swamp, Shirttail and Doe Branches enter  the
 stream between WQ-2 and WQ-3.   Color levels are higher downstream  (as
 expected) as a result of confluence with streams of higher color  levels
 (Shirttail, Gum Swamp, and Doe Branches).  Acidity and alkalinity  are
 both lower downstream, probably as a result of higher color levels.
 Nitrogen levels are also higher downstream, however, nitrate-nitrite is
 much higher indicating the possibility of fertilizer input from Gum
 Swamp or Doe Branch.   Total phosphorus levels are very similar (0.725
 through 0.774 mg/1) and are made up primarily of ortho-phosphorus  (80 to
 90  percent).  Dissolved oxygen, BOD, metals and coliform levels did not
 change significantly  downstream.

 Payne Creek Downstream of Site
 Two stations (WQ-13,  WQ-14) east of Complex I,  above and below the
 Little Payne Creek  confluence,  were sampled between September 1981 and
 June 1982.   The stream cross-sections at these  stations are generally
 well-defined with steep banks.   The stream bottoms  were primarily sand.
 The areas were moderately wooded with some understory.   These data are
 summarized  in Table 7.1.4-17.   These stations  represent the accumulation
 of  all CF runoff, and  can be used to assess the  influence of  Little
 Payne  Creek  on  water quality.

General  Parameters
Color  levels  were similar  between upstream and  downstream stations (93
 and  85  PCU)  and represent  no significant  change  from  stations  further
 upstream  (87  PCU at Station WQ-3).   Suspended matter  was  low  at  both
 stations, however,  November  1981  samplings  showed higher  values
 (>100  NTU),  a phenomenon! which  was  also  observed  upstream.  Methylene
Blue active  substances  and  oil  and  grease  were  low  at both  stations.

Dissolved Ions
Specific  conductance was  higher  at  the downstream station
(320 umhos/cm), and lower  upstream  (266  umhos/cm).  These  levels
                                    7-56

 represent  a Total  Dissolved Solids range of 176 to 280 mg/1 downstream
 and  146  to 239  mg/1  upstream.   No significant difference in dissolved
 ion  concentration  from  upstream was detected.

 Alkalinity and  pH
 Alkalinity was  highest  downstream (66  mg/1),  however levels were not
 significantly different (59 mg/1  at WQ-13)  and did not differ greatly
 from stations further upstream (64 mg/1 at  WQ-3).   Measurements of pH
 revealed near neutral conditions  at Stations  WQ-3, WQ-13,  and WQ-14.

 Nutrients
 Total Kjeldahl  nitrogen levels were similar at both stations and further
 upstream (0.81  to  0.92  mg/1),  however  nitrate-nitrite  showed a gradual
 increase in  concentation  with  progression downstream.   Payne Creek
 exiting CF property averaged 0.222 mg/1 nitrate-nitrite while just above
 the  Little Payne Creek  confluence measurements averaged 0.568 mg/1
 reflecting higher  levels  with  greater  drainage basin area.   Confluence
 with Little  Payne  Creek greatly increased nitrate-nitrite  levels;
 measurements averaged 1.56  mg/l  at Station  WQ-14.   Total phosphorus
 concentrations  were slightly higher downstream of  Little Payne Creek
 (0.705 mg/1), but  lower than values found at  Station WQ-3  (0.774 mg/1).
 Ortho-phosphate was the primary constituent of the total phosphorus,
 ranging from 80 to 90 percent.

 Dissolved Oxygen/BOD
Dissolved  oxygen and BOD  levels  were similar  at both stations and
 upstream (DO »  7.3 to 7.7 mg/l;  BOD »  1.3 to  1.5 mg/1).

Metals
Metals values were similar  to  those near  CF property;  cadmium,  however,
decreased downstream of confluence with Little Payne Creek.   Mercury and
zinc violated water quality standards  at  both stations  and  cadmium
violated standards only upstream  of Little  Payne Creek.

Microbiology
Fecal coliform  levels appeared to increase  after confluence with Little
Payne Creek.  Average values increased  from 177 to 311  MPN/lOOral.
                                    7-58

Troublesome Creek
The headwater wetlands  for Troublesome Creek are contained in the south
central portion of  the  CF property.   The  drainage basin on the property
comprises  approximately 0.9  square  miles  of the upper headwaters for the
Troublesome Creek system.  The  property contains no defined channel or
conveyance system.  The systems on  the property are characterized by
seasonably wet marshes  and a  small  maple  hardwood swamp.

Although no samples were collected  in Troublesome Creek on the CF site,
data have  been collected downstream of the site at MCC-5 and SW-11
during previous studies of the  Mississippi Chemical Company and Farmland
proposed mine sites.  The locations  of these stations are shown in
Figure 7.1-8 and the data are summarized  in Table 7.1.4-18.

Water quality in Troublesome  Creek  is similar to that of streams drain-
ing Complex II.  Color  levels are almost  as high as the most colored
stream draining Complex II (294 PCU)  and  this is reflected in the
slightly acidic conditions CpH  » 6.11).  The stream may be more acidic
if not for the buffering capacity in the  stream; alkalinity was high in
comparison to other streams draining Complex II (64 mg/1).  Specific
conductance averaged 229 umhos/cm indicating a Total Dissolved Solids
level of 126 to 206 mg/1.  Nitrogen levels were lower than the other
streams, however nitrate-nitrite was  much higher (1.09 mg/L).  Some
nitrogen data appear to conflict (TKN and Org N), however, this is
probably the result of  different samples  collected and one high organic
nitrogen measurement (36 mg/l). Total phosphorus was moderate in
comparison to other streams draining Complex II and was made up
primarily  of ortho-phosphate  (68 percent) .  Dissolved oxygen was higher
than in the other streams (6.7  mg/l)  and  BOD was observed at a
comparable level (3.40  mg/l).

Violations of Water Quality Criteria
Violations of water quality criteria have been assessed for EIS monitor-
ing and historical data, and  are summarized in Tables 7.1.4-19 and
7.1.4-20.

 Streams  in Horse Creek Basin primarily violated alkalinity and dissolved
 oxygen criteria.   Horse Creek violated the <20 rag/1 as CaC(>3
 alkalinity criteria  in all  three EIS monitoring samples, indicating the
 poor  buffering  capacity of  the stream.  The dissolved oxygen criteria of
 5.0 mg/1  was  also violated  in all samples.

 In the streams  draining Complex II to Payne Creek, a number of criteria
 were  violated.   Alkalinity,  pH, DO,  iron,  mercury and zinc criteria were
 violated  in all  streams and  the cadmium standard was violated in one of
 five  samples  in Doe  Branch.   Alkalinity was violated most often in
 Shirttail  Branch (71  percent of samples) and in only one or two samples
 for the other streams.   A similar trend was observed in pH violations;
 Shirttail  Branch  had  a  pH of <6.0 in 67 percent of the samples while the
 others were in  violation in  30 percent or  fewer of the samplings.

 Dissolved  oxygen  criteria were violated in all samples except in
 Plunder Branch  where  80 percent of the samples violated standards.  Iron
 and zinc standards were violated  in  40 to  75 percent of the samples
 while the  mercury standard was violated in 75 to 100 percent of the
 samples taken.   EIS monitoring revealed no violations of fecal coliform
 levels, however,  Plunder Branch has  historically violated the standard
 in 10 percent of  the  samples.

 Tributaries draining  Complex I to Payne Creek violated several standards
 including  alkalinity,  pH, DO,  cadmium, mercury, zinc, iron, and fecal
 colifonus.  The  alkalinity standard  was violated during EIS monitoring
 by Gum Swamp Branch (only 10 percent  of samples) but historically  Hickey
 Branch (1  percent), Payne Creek (5 to 10 percent)  and Gum Swamp Branch
 (50 percent of  samples)  all  showed some violations.   Violations of the
 upper pH standard  (>8.5) were  observed in  Hickey Branch in 1  to
22 percent  of the  samplings, while violations  of the lower  pH standard
 (6.0)  were  observed in Gum Swamp  Branch (I  to  22 percent).   Payne  Creek
violated the lower pH standard  only  once both  historically and  during
EIS monitoring.   DO violations  were  observed least frequently in Hickey
Branch (0 to 1 percent)  and most  frequently  in Gum Swamp Branch (30
percent).  Violations of cadmium, mercury  and  zinc standards  were
                                       7-64

-------
observed at all stations (20 to 75 percent)  and  iron  violated  standards
in Gum Swamp Branch in 1 out of 4 samplings.  Fecal coliform violations
were not detected during EIS monitoring, but historically violations
have been detected in all streams in  1  to 5  percent of  the  samplings.

Violations of water quality standards for pH, DO,  alkalinity,  iron  and
fecal coliforms were observed  in Troublesome Creek downstream  of  the CF
property.  Alkalinity standards were violated in I out  of 7  samples
while the lower pH standard was violated in 3 out  of  18.  Dissolved
oxygen levels were below 5 rag/1 in 5 out of  18 samples.  Iron  violated .
standards in 3 out of 7 samples and  fecal coliforms were at  violating
levels in 2 out of 19 samples.

Stations on Payne Creek near Little Payne Creek  violated alkalinity, pH,
DO, cadmium, mercury and zinc  standards.  Alkalinity  (10 percent) and  pH
(20 percent) violated standards only  at the  upstream  station indicating
moderating effects of Little Payne Creek.  Dissolved  oxygen  standards
were violated at both stations in 10  to 20 percent of the samples.
Mercury and zinc violated standards  in  2 out of  4  samples at both
stations and cadmium was in violation on 1 out of  4 samples  at the
upstream station.

Sampling of Sediments and Mine Discharge Samples
In order to characterize the quality of discharge  water from the
proposed mine site, ESE collected water quality  samples from the water
recirculation system at the two overflow weirs (MDW-1 and MDW-2)  in CF's
existing clay settling pond once each season (see  Figure 7.1-9).  The
results of this sampling have been summarized in Table  7.1.4-21.  These
data will be used for the impact assessment  discussions, since they are
site-specific (Complex I).  However,  the concentrations measured  are
probably worse than those expected from Complex  II because  the samples
collected represent mostly recycled water with little ground water
make-up water (approximately 0.08 percent of total recirculation  flow  at
Complex I).  On the other hand, the proposed water balance  for
Complex II, which specifies a  total CF  discharge of 3.8 cfs, assumes a
ground water pumping rate of 7.5 cfs  (approximately 5.3 percent of  the
total recirculation flow).  Therefore,  water quality  concentrations on
Complex II should be diluted from those measured in Complex I.

ESE also collected  sediment  samples  at  Stations  WQ-2,  3,  5,  8,  and 10 in
October 1981 and the results of  these samplings  are  presented in
Table 7.1.4-22.

Chemical content of waters  is  generally a  reflection of sediment
content, due either to dissolution or deposition.  This can  be  seen in
many of the sediment samples taken  from water  quality stations  during
October 1981.

Stations in Shirttail Branch,  Doe Branch,  and  Plunder Branch all had
sediment samples taken and  analyzed.  Acidity  in the sediment appeared
to be directly correlated with alkalinity  in the water column and may
reflect the buffering capacity of the sediment.   Nitrogen levels are
also consistent between water  and sediment;  October  1981  showed high TKN
values for Station WQ-10 in  both sediment  and  water.  In  contrast,
phosphorus water concentations did not  correlate with sediment
concentrations.  Metals which  exceeded  water quality standards  (cadmium,
mercury, iron, zinc) were higher in  sediments  from these  stations than
other sediments sampled.

Other sediments sampled during October  1981  were from two Payne Creek
stations (WQ-2 and WQ-3).   These stations  both had moderate  levels of
alkalinity and neutral pH in the water  column.  This was  also observed
in the sediment pH which is  near neutral.  Nitrogen  levels were low in
both water and sediment.  Phosphorus concentrations  were  not correlated
between sediment and water.  Metals  appeared to  be low in sediments,
however, cadmium, mercury,  and zinc  violated water quality standards.

7.1.4.3  SUMMARY
Water quality of streams at  the mine site  can  generally be separated
into two large groups—those draining Complex  II,  and those  draining
Complex I.  Streams draining Complex II are  impacted from swampland more
than those draining Complex  I.  Color levels are higher and  pH  and
alkalinity are lower indicating  primarily  acidic conditions.  Dissolved

oxygen is lower in Complex II streams,  probably as a  result of  contact
with swampland.  Nutrient levels are about  the same  in  the streams
draining both Complexes.  However, nitrate-nitrite levels are high  in
Complex I, probably as a result of fertilizer input.  Zinc and  mercury
violated water quality standards in both basins; iron violated  standards
most often in Complex II streams; cadmium violated standards more often
in Complex I.

All on-site streams, except for Horse Creek, Brushy Creek, Troublesome
Creek and Lettis Creek drain into Payne Creek.  Water quality in Payne
Creek after inputs from all streams is  generally similar to that of
streams in Complex I.  Alkalinity, pH,  nutrient, and DO levels  are  all
comparable to Payne Creek levels before entering CF property.   Little
Payne Creek has a moderating effect on  alkalinity, pH,  arid cadmium
levels, but increases nitrate-nitrite levels.

Effective January 1, 1986, CF modified  its  surface water monitoring
program after generating a 10-year data base.  In this  revised  program,
continuous surface water streamflow data and water quality information
are being generated at Stations WQ-3 and WQ-7.  Station WQ-3 is located
on Payne Creek, and Station WQ-7 is located on Hickey Branch (see Figure
7.1-3).

                           8.0   AQUATIC ECOLOGY
                     8.1   THE  AFFECTED ENVIRONMENT
8.1.1  REGIONAL DESCRIPTION
Two  central Florida  aquatic community types  were identified in the
Phosphate  Industry Areawide Environmental  Impact Statement (U.S.
Environmental Protection Agency,  1978).  Standing water,  or lentic,
aquatic communities  is one  type which includes natural  or manmade lakes
and  impoundments, ponds, pits  and seasonal or  permanent wetlands.
Except for some interconnections  between low lying wetlands,  the  lentic
communities represent essentially discrete ecosystems.   Many  of the
smaller lentic systems are  intermittent, generally becoming dry during
early spring.  They  provide support  for transitio.nal  communities  during
only part of the year.  Most of the  natural  large lentic  water bodies
have permanent water.  They are shallow with wide littoral zones  which
support comparatively large  populations of aquatic flora  and  fauna.

A second aquatic community  type is  the lotic,  or flowing-water,
community, which includes rivers,  streams and  their tributaries.   Most
of these systems have water  that  is  stained  red-brown due to  humic acids
being washed downstream from adjacent lentic systems.   The streams are
relatively slow-moving and moderately to densely covered  with emergent
aquatic vegetation.  They usually have well  developed shoreline terres-
trial communities.   Flows vary  greatly between wet and  dry seasons.
During the dry season, stream  flow  is confined to main  channels while
most of the smaller  tributaries cease flowing  and either  form a series
of pools, or become completely dry.   During  the  wet season, streams
become contiguous with lentic  systems within the floodplain.   A divers-
ity of flora and fauna utilize lotic  habitats.

CF Industries'  proposed Hardee Phosphate Complex II is  located in a
portion of central Florida which  is devoid of  major lakes.  The primary
lentic systems within this  area are composed of  either  seasonal or
permanent wetlands.   Lotic systems within CF Hardee Phosphate  Complex II
are comprised of 2nd and 3rd order  streams that  are seasonally
                                    8-1

-------
influenced.  Horse Creek is a 2nd order  stream,  and  all  others are 3rd
order.  In this phosphate mining  region,  drainage  patterns have been
altered in many places by channelization  for  flood prevention or for
agricultural (citrus, cattle) purposes.

8.L.2  SITE-SPECIFIC DESCRIPTION
CF Industries' Hardee Phosphate Complex  II comprises  agricultural lands
(cattle), flatwoods, hardwood hammocks,  riparian forests,  marshes,  and
sloughs.  As discussed in Section 7.0, portions  of ten drainage systems
within the Peace River drainage basin are present  on  this  site:
     1.  Horse Creek
     2.  Brushy Creek
     3.  Shirttail Branch
     4.  Doe Branch
     5.  Plunder Branch
     6.  Coon's Bay Branch
     7.  Lettis Creek
     8.  Troublesome Creek
     9.  Gum Swamp Branch
    10.  Hog Branch

Only Lettis Creek and Troublesome Creek  have  poorly defined  on-site
drainages, as they represent only the upper extremities  of their
respective watersheds.  All other systems have defined on-site streams
or channels.   At least one aquatic ecology sampling station  was
established in the vicinity of the property boundary  and channel exit
point for each of the six major drainage  systems (Figure 8.1-1).
Additional sampling stations were established  for  Horse  Creek and Brushy
Creek to provide further documentation of these  stream habitats.  The
property is located on a regional drainage divide  with the western half
of the property draining south and the eastern half draining to the
north and then east.  Specific descriptions of sampling  stations are
provided in the following paragraphs.

8.1.2.1  HORSE CREEK
Of the eight systems, Horse Creek  is  the  only  system which does not
begin as a headwater area on the property.  Horse  Creek  flows
intermittently in a southerly direction within the property,  and has  an
average annual flow of over 5 cfs  at  the  point where it  leaves  the
property.  The headwater region of Horse  Creek lies about  4 river miles
north of the property.  Initially, only one sampling station  (HC-S) was
located within a laurel oak hammock near  the southern property  boundary.
The channel at this location was approximately 15  meters wide and
1 meter deep during the dry season.   Stream reaches above  and below  the
sampling location were less channelized.

Two additional stations were included  in  October  1981.   One station,
Horse Creek-Middle, HH, was centrally  located  along the  stream  course
on-site and within a marsh dominated  by a mixed assemblage of maiden-
cane, pickerelweed, galingale, and buttonbush. Water depths  at
Station HC-M were generally less than  0.5 meter and the  channel was
relatively diffuse.  The northernmost  Horse Creek  station  (HC-N) was
near the northwestern property boundary and within an oak  hammock/pine
flatwoods area.  At this station,  the  channel  was  well defined; however,
it was narrower (5 to 10 meters) and  shallower (0.25 meters to
0.5 meters) than at Station HC-S.

8.1.2.2  BRUSHY CREEK
The major portion of Brushy Creek's headwaters are within  the site's
boundaries.  Although they are separate systems on-site, Brushy Creek
becomes a tributary to Horse Creek approximately 20 kilometers  south  of
the property.  The Brushy Creek drainage  system includes two  lobes of
hardwood swamp/herbaceous marsh which  are separated by a dirt road.
Mitchell Hammock is the largest of the two lobes and is  located east  of
Brushy Creek's main channel.  Initially,  one sampling station (BC) was
established in a pickerelweed/arrowhead marsh  along the main channel.
This area was chosen primarily because of the  persistence  of  an aquatic
habitat within the "pool" area of  the marsh.   As with all  of  the
drainage systems during the initial sampling trips, the  drought of the
                                8-4

-------
preceding year had diminished aquatic habitats,  complicating  selection
of aquatic ecology sampling stations.

One additional sampling station (BC-2) was  located  in  an herbaceous
marsh on the perimeter of a tupelo swamp  which  received  flow  from
Mitchell Hammock.  This station was sampled only in October 1981.

Four stations were added to represent Mitchell  Hammock:  Ml was  located
along a transect within a maple/tupelo swamp, M2 and M3 were  within
separate maidencane marshes, and M4 was  located in  a raaidencane/
pickerelweed/arrowhead marsh.  The marsh  containing M4 eventually
channelized and connected to the main body  of Brushy Creek through
BC-2.  These Mitchell Hammock stations were sampled only in February
1982.

8.1.2.3  SHIRTTAIL BRANCH
Shirttail Branch was the only drainage system in the western  section of
the property that had a northerly flow, becoming a  tributary  to  Payne
Creek.  The aquatic ecology station (SB)  was  located in  a  pooled  (0.5 to
1.0 meter deep and 8 meters wide) area along the northern  boundary.
This area was connected to a laurel oak  hammock by  a well  defined
channel.  No additional sampling stations were  added for this drainage
system throughout the program.

8.1.2.4  DOE BRANCH
Doe Branch represents Che largest and most  complex  drainage system on
the CF Hardee Phosphate Complex II site.  The headwaters of Doe  Branch
are located near the southern property boundary and, when  flowing,
become a tributary of Payne Creek approximately I mile north  of
Highway 62 (which is a part of the northern property boundary).   The
east and west pastures are separated by both a  railroad  and Fort  Green-
On a Road.  Portions of Doe Branch's western sub-basin  were isolated  by
this east-west boundary.  Only one aquatic  ecology  sampling station  (DB)
was established  for Doe Branch in a pool  which  drains  a  pop ash/hardwood
                                8-5

-------
swamp  forest, south of Highway 62.   Station  DB  was  between 25 and
30 meters wide and ranged  from 0.75 meters  to  1.5 meters  in depth.   The
hardwood swamp channel was included  for  qualitative sampling during the
last three  sampling trips.

8.1.2.5  PLUNDER BRANCH
Plunder Branch is a complex drainage  system  consisting  of numerous
marshes and swamps which are interconnected  by  sand-bottomed channels.
Plunder Branch is also a tributary of Payne  Creek,  approximately
1 mile north of Highway 62.  The aquatic ecology sampling station,  PB,
was located in a small pooled area north of  Highway 62  and was  surround-
ed by a mixed hardwood swamp.  Most of the Plunder  Branch drainage
system is south of Highway 62 and within the CF Hardee  Phosphate
Complex II site.

8.1.2.6  COON'S BAY BRANCH
Coon's Bay Branch is a 3rd order intermittent stream course which,  when
flowing, connects to Payne Creek.  The headwaters for Coon's Bay Branch
are located within the extreme northeastern  corner  of CF  Hardee
Phosphate Complex II.  Areas off-site but adjacent  to the hardwood  swamp
have been altered for agricultural (citrus)  interests.  One aquatic
ecology sampling station (CB) was located in the main "channel"  of
Coon's Bay Branch along the northern  property boundary  and Highway  62.
The water level at this location seldom exceeded 0.2 meters  in depth  and
4 to 5 meters in width.

8.1.3  METHODOLOGY
Due to the complexity of each drainage system,  the  aquatic  sampling
program had to be designed to ensure  collection of  system-representative
populations.  The shallow nature of all six  systems  and their sampling
stations restricted the types of sampling methodology available  for use.
However, collection methods remained  consistent for  all sampling
efforts.
                                8-6

-------
Additional sampling stations were added for both Horse  Creek  and  Brushy
Creek during the final two sampling episodes.   In  addition,  four
transects with aquatic sampling stations were  included  in Mitchell
Hammock  for one sampling event  in February 1982.

8.1.3.1  PHYTOPLANKTON
Representative phytoplankton samples were collected  from just below the
surface at all stations.  Samples were preserved with Acid-Lugol's
solution.  An aliquot of 800 milliters was concentrated by  sedimentation
to a final count volume of 5 milliliters.  Population estimates were
derived  from counts in a Palraer-Maloney Chamber.   At  least  200 cells
were counted from each sample utilizing a magnification of  400X.  Counts
were converted to cells per railliliter.

Algal dominance was defined by  the algae with  the  greatest  abundance  at
a particular station.  Codominant algae were  those algae which comprised
10 percent or more of the population density.

8.1.3.2  PERIPKYTON
Submerged twigs, rocks and aquatic macrophytes were  sampled by scraping
off sections of the attached periphyton community.  Diatoms were  acid
cleaned  and mounted on slides for microscopic  examination  at  1000X
magnification.  Other algal groups were examined qualitatively under  the
compound microscope to obtain presence/absence data  for each stream
station sampled.

8.1.3.3  BENTHIC MACROINVERTEBRATES
Infaunal benthic macroinvertebrates were sampled quantitatively  with  a
10.8-centimeter (internal diameter) stainless  steel  coring  device which
penetrated sediments to a depth of 15 centimeters.  Each  sample  was
washed through a 0.5 millimeter mesh sieve and preserved with a
10 percent formalin solution containing rose  bengal  stain  (Mason  and
Yevich,  1967).  During the initial sampling effort in July 1981,  three
core samples per station were collected.  Beginning  in  August 1981, a
                              8-7

-------
total of nine cores  per  sampling  station  were collected and sieved in
the  field.   Six  cores  per  station were  processed for quantitative
population estimates.  The  remaining  cores  were  stored for future use on
an as needed basis  to  refine  the  quantitative data.

Epifaunal macroinvertebrates  were sampled qualitatively with Hester-
Dendy multiple plate artificial  substrate samplers,  a 0.5-millimeter
mesh dip net, and 30-centimeter  square  0.5-millimeter mesh drift nets.
HesCer-Dendy samplers  were  suspended  for  4  weeks from stationary
structures so that they  hung  just above the sediment/water interface.
Colonization was allowed to occur for approximately  one month.   Attached
organisms were removed and preserved  as described  for the infauna.

  »
Following a  field visit  by  an EPA project team in  October 1981,  the
quantitative sample collection was  replaced by a more intensive  qualita-
tive survey of all stream stations.   This change was requested  by EPA to
allow greater collection coverage and,  therefore,  more population
information on the diverse habitats present around each sampling
station.

8.1.3.4  FISH
Dip netting was used to  collect  small fish  at most sampling locations.
Where possible, a beach  seine was  used  to sample larger fish in  wide
channels and pools.  Representative individuals  of each taxon were
preserved and retained as reference specimens.   All  remaining fish were
returned to the water unharmed.

8.1.4  COMMUNITY ANALYSIS
8.1.4.1  PHY TOPLANKTON
Algal populations found  on the CF Hardee  Phosphate Complex II site
generally fit into two categories:  (1) phytoplankton (free-floating),
and (2)  periphyton (attached).  Both  populations are integrated  in
shallow water.   Algal populations  are important  primary producers in
lakes,  ponds, and rivers.  In areas of  extensive marsh with intermittent
flooding, rooted vascular plants  are  the  major primary producers  and the
                                8-8

-------
importance of phytoplankton is diminished.  However, Che stems of
vascular plants and other substrates may be a source of attachment  for
periphyton.

Descriptions of populations found on the OF Hardee Phosphate Complex II
site are based on the results of five sampling periods:  July, August,
September, and October 1981; and February 1982.  Presence/absence
matrices of taxa identified at each sampling station and during each
trip are found in Tables 8.4.1-1 through 8.4.1-5.

July 1981
Phytoplankton populations in Horse Creek were dominated by  the
blue-green alga, Anabaena sp., which comprised 56.6 percent of the  cells
counted (Table 8.1.4-6).  Green algae made up most of  the remaining
cells, with Chlamydomonas sp. accounting for 13.8 percent of the total.
Ch1amydomonas sp. was dominant in Brushy Creek (35.6 percent of the
total), along with other green algae and the diatoms,  Melosira sp.  and
Nitzschia sp.

The Shirttail Branch phytoplankton community was dominated  by
Chlamydomonas sp. (28.2 percent of the cells) and other unidentified
green algae (11.7 percent) in July 1981.  Other numerically important
algae found in Shirttail Branch included the euglenophyte,  Trachelomonas
volvocina (19.4 percent), and the cryptophyte, Chroomonas sp.
(13.6 percent).

The diatom, Navicula confervacea, comprised 31.7 percent of the total
cells counted from Doe Branch samples, followed by the blue-green  alga,
Oscillatoria sp. (22.2 percent).  Chlamydomonas sp. and other  species  of
diatoms were also abundant in this stream.

Euglenophytes were dominant  in Plunder Branch during  the July  1981
sampling effort (Table 8.1.4-6); Euglena gracilis  (27.3 percent) and
Trachelomonas volvocina (16.7 percent) were the most  abundant  species  in
                                8-9

-------
this group.  The cryptophyte, Chroomonas nordstedtii (18.3 percent), and
Chlamydomonas sp. were also relatively important in Plunder Branch.  Of
the six sampling stations, Coon's Bay Branch was the only creek that was
completely dry during the July 1981 trip.  Phytoplankton populations in
the remaining creeks had densities which ranged from 10,110 cells/ml in
Plunder Branch to 607 cells/ml in Shirttail Branch (Table 8.1.4-7).  A
total of 66 taxa were enumerated for all stations, ranging from 26 taxa
at Horse Creek to 36 taxa at Brushy Creek.  Although population
densities were low, the algal taxa were fairly evenly distributed, as
evidenced by species diversity, evenness, and richness (Table 8.1.4-7).

August 1981
The density of blue-green algae in Horse Creek declined in August 1981,
when compared with July 1981.  Green algae, particularly
Chlamydomonas sp., were dominant, accounting for 56 percent of the total
cells identified (Table 8.1.4-8).  Chroomonas sp. and Nitzschia palea
each accounted for more than 10 percent of the total phytoplankton
community in Horse Creek during August 1981.

Chlamydomonas sp. (41.4 percent of the total) continued to be the domi-
nant alga in Brushy Creek, and various euglenophytes comprised most of
the remaining cells.  A shift in dominance was observed in Shirttail
Branch populations in August 1981, when the blue-green alga,
Oscillatoria geminata, was the most abundant species (29.9 percent),
followed by Chlamydomonas sp. (13.9 percent), and Nitzschia sp.
(13.7 percent).

Diatoms continued to be the most abundant algae in Doe Branch,
(76 percent of the total) with species of Nitzschia and Navicula
accounting for the majority of the ceils (Table 8.1.4-8).  Blue-green
algae declined in relative importance to 11 percent of the total.

The two dominants in Plunder Branch during July 1981, Chlamydomonas sp.
and Chroomonas nordstedtii, were also dominant during August 1981.  The
                                 8-10

-------
euglenophytes, Lepocinclis  fusiformis  and  Trachelomonas  pulcherrima,  and
the  pyrrophyte, Glenodinium sp., each  represented  over  10 percent  of  the
total cells collected in Plunder Branch during  August.   Total
phytoplankton abundance (Table 8.1.4-7) followed  the  trend observed  in
July 1981, with highest densities  found in Plunder  Branch
(7,132 cells/ral), and lowest densities  found  in Shirttail Branch
(324 cells/ml).

September 1981
Green algae continued to be  the dominant group  in Horse  Creek  during
September 1981 with Hyalotheca sp. and unidentified flagellated green
algae accounting for most of the cells (Table 8.1.4-9).   Several species
of diatoms comprised an additional 23  percent of the  phytoplankton
community.  Blue-green algae, particularly Oscillatoria  geminata,  were
dominant in Brushy Creek (57 percent of the total), and  chrysophytes
represented 20 percent of the cells counted.

The species composition in  Shirttail Branch during  September 1981 was
different from the species  composition during each  of the two  preceding
months.  Navicula confervacea accounted for 64.7 percent  of the total
cells identified in September 1981, and all the diatoms  taken  together
comprised 79 percent of the algal population (Table 8.1.4-9).  Green
algae made up most of the remaining cells,  with 19  percent of  the  total.
Doe Branch algal populations were codorainated by several  groups,
including chrysophytes (32 percent), green algae (25  percent), diatoms
(22 percent), and euglencphytes (10 percent).

Diatoms were dominant in Plunder Branch during  September  1981, unlike
during the previous sampling efforts, accounting for  89  percent of the
total cells identified.   Navicula confervacea was the most abundant
species in Plunder Branch,  as it was in Shirttail Branch, with
18.4 percent of the total cells.
                               8-11

-------
The phytoplankton community in Coon's Bay Branch was dominated  by
unidentified flagellated green algae (83.9 percent) in  September  1981.
Cryptophytes and diatoms made up the remainder of the Coon's  Bay Branch
population.  Total densities ranged from 148 cells/ml in Coon's Bay
Branch to 1,600 cells/ml in Plunder Branch (Table 8.1.4-7).

October 1981
The three stations sampled in Horse Creek during October 1981 had
similar algal communities.  Green algae, cryptophytes,  and diatoms all
made up substantial fractions of the total cells counted
(Table 8.1.4-10).  Numerically dominant species in Horse Creek  included
the green alga, Chlamydomonas sp.; the cryptophyte, Chroomonas  sp.;  and
the diatom, Nitzschia sp.  Blue-green algae continued to be  important in
Brushy Creek during October 1981 (23 percent), but several species of
diatoms together comprised 69 percent of the total cells identified.

The blue-green alga, Oscillatoria geminata, was dominant in  Shirttail
Branch with 55 percent of the population (Table 8.1.4-10).   Unidentified
flagellated chrysophytes and Chroomonas sp. accounted for most  of  the
remaining cells found in Shirttail Branch during October 1981.

Chroomonas sp. was also abundant in Doe Branch, accounting for
42.1 percent of the total cells.  Oscillatoria sp. and  an unidentified
flagellated chrysophyte each represented more than 11 percent of  the
algal population in Doe Branch.

Chroomonas sp. was also abundant in Plunder Branch during October  1981
(30.1 percent), but euglenophytes, particularly Lepocinclis  sp. and
Trachelomonas volvocina, were dominant, with 59 percent of the  total
cells.  Total densities ranged from a mean of 505 cells/ml for  the three
stations in Horse Creek to 7,376 cells/ml in Brushy Creek
(Table 8.1.4-7).
                               8-12

-------
February 1982
There was considerable variation in the algal communities observed  at
the different Horse Creek stations during February  1982
(Table 8.1.4-11).  The Cijrptophyte, Chroomonas nordstedtii,  was  dominant
at the southernmost station (HC-S), with 63 percent of the total cells.
Several species of diatoms combined accounted for a total of 65  percent
of the cells at the central station (HC-M), and algal dominance  was
evenly divided among green algae, euglenophytes, chrysophytes, and
eryptophytes at the northernmost Horse Creek station (HC-N).

Blue-green algae were not found at all in Brushy Creek during February
1982, unlike previous months.  Trachelotnonas volvocina was the dominant
species (40.7 percent) during the winter sampling episode, followed  by
several species of diatoms and green algae.

T\ volvocina was also the single most abundant  species in Shirttail
Branch during February 1982 with 30.5 percent of the total cells.   Other
numerically important algae found at that time  included  green algae,
eryptophytes, and diatoms.

Several species of diatoms, including Eunotia sp. (23.4  percent) and
Achnanthes hungarica (16.4 percent), taken together accounted for
73 percent of the total cells collected in Doe  Branch  in February  1982
(Table 8.1.4-11).  Species of green algae, eryptophytes, and diatoms
were all numerous in Plunder Branch collections, with Chroomonas
nordstedtii representing the dominant species (37.2 percent  of total
cells).  Diatoms comprised 74 percent of the total  cells found in  Coon's
Bay Branch during February 1982, with Nitzschia sp. accounting for
50.3 percent of all cells (Table 8.1.4-11).

Four transects in Mitchell Hammock were sampled for phytoplankton  during
                          t
February 1982.  Transects 1 and 4 were dominated by diatoms
characteristic of nonsubmerged to shallow water areas  (Lowe, 1974).
Transect 2 was dominated by one species, Synura uvella,  which  is
                                8-13

-------
flagellated and therefore more mob Lie  than diatoms.   The  cryptophytes,
chlorophytes, and euglenophytes  numerically  dominant  at Transect  3 are
characteristic of an area receiving organic  loading.   Total
phytoplankton densities during February  1982 ranged  from  941  cells/ml  in
Doe Branch to 30,768 cells/ml in Mitchell Hammock  Transect  2
(Table 8.1.4-7).

Analysis of algal populations found on the CF Hardee  Phosphate
Complex II site reveals two basic species groupings.   Several diatom
genera which were dominant or codominant  at  many of  the stations  are
characteristic of shallow systems and  were of a benthic or  epiphytic
origin.  In these shallow areas, phytoplankton supply a small portion  of
the total primary production, due to the  presence  of  vascular plants.
However, the algae are important as food  for grazing  macroinvertebrates.
The second species group includes cryptophytes, chlorophytes, and
euglenophytes which are characteristic of areas with  permanent  water
receiving organic loading, such  as stock  ponds.

8.1.4.2  PERIPHYTON
Periphyton samples were collected at the  CP  Hardee Phosphate  Complex II
site during five sampling periods:  July, August,  September,  and October
1981; and February 1982.  As discussed previously  in  the  phytoplankton
section, phytoplankton and periphyton  populations  interact  in shallow
water, and sharp distinctions between  the communities  become  impossible.
Periphyton growth is often extensive on stems  of vascular plants,
submerged tree trunks and limbs, and other surfaces available in shallow
water.  Periphytic organisms are grazed upon by many  aquatic
invertebrates as well as some fish.

An examination of the presence/absence matrices for periphyton  taxa
identified from each of the five collecting  efforts (Tables 8.1.4-12
through 8.1.4-16)  reveals lists of algae closely resembling the phyto-
plankton list of taxa (Table 8.1.4-1).  The  similarity in populations of
algae collected from different habitats (attached versus  free-floating)
underscores the significant interaction between the phytoplankton  and
                               8-14

-------
periphyton in the predominantly shallow waters  of  the  CF  Hardee
Phosphate Complex II site.  Most of  the periphyton were  species typical
of shallow water bogs or marsh systems.  Many of  these,  particularly the
diatoms, have resting stages that  are  resistant to desiccation.  The
resting stages remain viable in the  soil surface during  the  dry season,
ready to initiate rapid asexual reproduction when  the  area is
re flooded.

8.1.4.3  BENTHIC INFAUNA
Benthic infauna are aquatic invertebrates  which live  in  the  substrate
and are generally large enough to  be seen  with  the unaided eye.  They
feed on a variety of organic materials  including  detritus, algae, and
other invertebrates, and are important  food  items  for  larger
invertebrates, fish, and some water  fowl.  Benthic invertebrate
communities have been analyzed for their capacity  to  reflect
environmental quality, especially  degradation  in  water quality due to
organic pollution.  Since benthic  invertebrates have  relatively long
life cycles, are limited in mobility,  and  occupy  diverse  aquatic
habitats, they are indicators of present and past  water  quality,
substrate type, and flow regime.

Characterizations of benthic infaunal  populations  found  on the CF Hardee
Phosphate Complex II site are based  on  the results of  five sampling
periods:  July, August, September, and  October  1981;  and  February 1982.
Not all stations were sampled during all field  efforts.   A list of the
taxa identified and presence/absence matrices  by  trip  are presented in
Tables 8.1.4-17 to 8.1.4-21.

July 1981
Oligochaete worms accounted for 90 percent of  the  benthic infauna
collected in Horse Creek during July 1981  (Table  8.1.4-22).   Most of the
individuals were the tubificid, Limnodrilus  hoffmeisteri, and immature
tubificids which probably also represented L.  hoffmeisteri.
                               8-15

-------
 Populations  in  Brushy  Creek were  also  dominated by tubificids
 (85  percent  of  the  individuals) which  were mostly immature.  Beetles of
 the  family Heteroceridae made  up  the remaining 15 percent of the indivi-
 duals  found  in  Brushy  Creek (Table  8.1.4-22).

 Core samples  from Shirttail Branch  were  relatively evenly populated by
 tubificids and  chironomid  larvae.   Insects were dominant in Doe Branch,
 where  two chironomid species and dragonfly larvae combined to account
 for 80 percent  of the  organisms.  Immature tubificids and one species  of
 naidid oligochaete were the only  infauna collected from Plunder Branch
 (Table 8.1.4-22).  Highest  total densities were found in Brushy Creek
 during July  1981 (3,175 individuals/m2)  and lowest densities were
 found  in Doe  Branch and Plunder Branch (182/ra2).

 August 1981
 Oligochaete worms continued to numerically dominate the infauna of Horse
 Creek  during  August 1981, comprising 97  percent of all  organisms
 identified.   The tubificid,  Aulodrilus pigueti, was the most abundant
 species collected (Table 8.1.4-23).

 Oligochaetes  also continued  their dominance in Brushy Creek (84 percent
of the total), with immature tubificids  forming the largest  group.
 Cores  from Shirttail Branch were again populated  by oligochaetes and
 insect larvae (41 percent and 59 percent  of total  individuals,  respect-
 ively) with larvae of midges (Chironomus  spp.)  comprising the roost
abundant group.  The only two species  of  infauna  collected  in Doe  Branch
during August 1981 were the  amphipod,  Hyalella azteca (50 percent  of the
 total) and the chironomid,  Polypedilum illinoense  (50 percent  of the
 total).  Plunder Branch samples were again strongly dominated by
oligochaetes, including immature individuals,  as  well as  tubificids  and
naidids.  These worms accounted for 93 percent  of  the organisms
collected in  Plunder Branch.  Total densities  were  highest  in Horse
Creek  during August 1981, at 6,114  individuals/m2,  and  lowest  in Doe
Branch, at 73 individuals/ra2 (Table 8.1.4-23).
                              8-16

-------
September 1981
Oligochaetes were still the dominant  infaunal group  in Horse Creek
during September 1981, but many more  species of tubificids and naidids
were  found.  Immature oligochaetes remained  the most  abundant group
collected.  A total of 20 percent of  the collections  was composed of
insect larvae, almost all belonging to the Chironomidae
(Table 8.1.4-24).

Brushy Creek collections also continued to be dominated by oligochaetes,
particularly tubificids.  Limnodrilus hoffmeisteri and immature tubifi-
cids  (probably also L. hoffmeisteri)  were the most abundant oligochaetes
found in Brushy Creek.  Several insect species, predominantly chirono-
mids, made up the remainder of the samples (Table 8.1.4-24).

The infauna of Shirttail Branch became more diverse  in September 1981,
although oligochaetes were still dominant, representing 65 percent of
the total organisms collected.  Various insect species accounted for
23 percent of the organisms, and molluscs, particularly gastropods of
the family Ancylidae, made up the remaining  13 percent of the total
(Table 8.1.4-24).

Naidid oligochaetes were the dominant group  in Doe Branch during
September 1981, when all oligochaete groups comprised 92 percent of the
organisms collected.  Tubificid oligochaetes, especially immature and
adult Limnodrilus hoffmeisteri, represented 99 percent of the infaunal
population at Plunder Branch during September 1981 (Table 8.1.4-24).

Several tubificid and naidid oligochaete species were identified from
Coon's Bay Branch core samples; all oligochaetes added up to 62 percent
of the total organisms counted.  The  remaining 38 percent of the
organisms were various insects, including Collembola  (springtails) and
several chironomid species.  Highest  total densities  were found in Horse
Creek, with 11,753 individuals/m , and lowest densities were found in
Brushy Creek, with 2,628 individuals/m2 (Table 8.1.4-24).
                              8-17

-------
October 1981
Three stations in Horse Creek were  the  only  sites  investigated  for
benthic infauna during October  1981.  As mentioned  previously,  the
emphasis on benthic communities  shifted  from quantitative  cores to
qualitative population samples  at the request of EPA  field  team members.
Oligochaetes and insects were the dominant groups  at  all  the  stations,
but there were differences in species composition  within  these  groups.
Limnodrilus hoffmeisteri and Aulodrilus pigueti were  the  dominant
tubificids at the southern Horse Creek  station (HC-S),  and  larval
chironomids were the dominant insects.  L. hoffmeisteri and A.  pigueti
were also dominant at the central Horse Creek station (HC-M), but the
most abundant insect was Caenis  sp., a  mayfly larva.   Populations at  the
northern Horse Creek station (HC-N) included the same oligochaetes  that
were found at the other stations in Horse Creek.   Two chironomid species
were the most abundant insects  found at this station.   Total  densities
at all three stations were similar, ranging  from 3,139 to  3,741
individuals/m2 (Table 8.1.4-25).

February 1982
Once again, the three stations  in Horse Creek were  the only stations
sampled.  In general, the populations were similar  at  all  stations, with
oligochaetes accounting for 61  percent  to 82 percent  of the total
organisms identified.  The central station was inhabited by a greater
variety of insect species than  the other two stations,  probably because
it was in a marshy area with a  greater variety of habitat  types.
Chironomid larvae comprised all  of  the  insects collected  at the northern
and southern stations in Horse  Creek.  Total densities  ranged from  1,186
individuals/m2 at the southern  station  to 310 individuals/m2  at the
northern station (Table 8.1.4-26).

The Shannon-Weaver diversity index calculated for  benthic  infauna ranged
from a low of 0.72 in Plunder Branch to a high of  3.97  in  Coon's Bay
over the first three collection  episodes (Table 8.1.4-27).  Diversity
generally increased from July 1981 to September 1981,  which resulted
                               8-18

-------
primarily from increases in species richness rather  than  species
evenness.  Doe Branch and Plunder Branch  stations  were  generally  the
least diverse due to low species richness.  The  low  species  richness  at
these two stations probably resulted  from bottoms  composed  principally
of organic fine sediments.

In Horse Creek during October 1981 and February  1982 the  highest  diver-
sity was displayed by the central station, which resulted from a  higher
species richness.  The higher species richness resulted  from the  greater
complexity of the habitat due to the aquatic macrophytes  present.

The benthic infauna in the streams on the CF Hardee  Phosphate Complex II
site were numerically dominated by a relatively  limited variety of
organisms.  Tubificid oligochaetes, especially Limnodrilus hoffmeisteri,
were ubiquitous during all sampling periods.  Several species of  insects
usually comprised the remainder of the samples,  with larval  chironomids
found most often.

8.1.4.4  EPIFAUNA
Epifaunal organisms are aquatic invertebrates living on  substrates  such
as vegetation, rocks, logs, etc.  Some of the species recovered in
infaunal core samples are also found  in epifaunal  samples, but the
assemblages found in the two habitats are usually  distinct.  Epifauna
feed on organic materials such as detritus, algae, and other inverte-
brates.  They are fed upon by other invertebrates, fish,  and some water
fowl.

The presence/absence data (Tables 8.1.4-28 through 8.1.4-32), although
qualitative, nevertheless reveal differences between sampling stations.
These data will be discussed separately for each trip.
                              8-19

-------
July 1981
Epifaunal populations sampled  in Horse Creek during July  1981  included
species of leech, gastropod, water mite, shrimp, and  insects belonging
to several families (Table 8.1.4-28).  Only a  few  species were  found  in
Brushy Creek; these included oligochaete worms, shrimp, and two species
of mosquito larvae.  The Shirttail Branch epifaunal community  also
included oligochaetes and a crustacean, but supported a more diverse
insect fauna than was found in Brushy Creek.   Various mayflies, water
scorpions, water beetles, mosquito larvae, and chironomids were
collected in Shirttail Branch during July 1981.  Few  epifaunal  species
were collected in Doe Branch; those found included one species of naidid
oligochaete, a gastropod, an amphipod, and five species of insects.
More epifaunal species were found in Plunder Branch than  at any other
»
station sampled during July 1981 (Table 8.1.4-28).  Various species of
oligochaetes, molluscs, and insects contributed to the diverse epifaunal
community found in Plunder Branch.

August 1981
A large number of epifaunal species was collected  in Horse Creek during
August 1981 (Table 8.1.4-29).  Many aquatic groups were represented
including turbellarians, oligochaetes, leeches, several molluscs, water
mites, various crustaceans, and numerous insect families  and species.
Considerably fewer epifaunal species were found in Brushy Creek than  in
Horse Creek, but most of the groups listed for Horse Creek were
represented by at least one species in Brushy  Creek.  More species of
insects were collected than any other group.   Shirttail Branch was
inhabited by relatively large numbers of oligochaete  and  mollusc
species, along with a moderate number of insect species.  Many of the
insects found in Doe Branch during August 1981 were not dipterans, which
were the dominant insect group at most stations.  Various mayflies,
dragonflies, beetles, and other insect groups  were represented  in Doe
Branch, as well as several dipterans.  Several species of the ubiquitous
oligochaetes were found, as well as some crustaceans  (Table 8.1.4-29).
Cpifaunal populations in Plunder Branch were similar  to those in Doe
                               8-20

-------
Branch, except that more species of molluscs and dipterans were  found  in
Doe Branch during August 1981.

September 1981
Large numbers of epifaunal species were collected  from  the six stations
sampled during September 1981 (Table 8.1.4-30).  The majority of  the
species collected at all stations were insects.  Various  species  of
oligochaete worms were found at each station; Coon's Bay  Branch  and
Horse Creek had the fewest species, and Plunder Branch  had the most
species of oligochaetes.  Leeches were found in Brushy  Creek, Doe
Branch, Plunder Branch, and Shirttail Branch.  Various  molluscs  were
collected at all stations except Coon's Bay Branch; Doe Branch supported
the most species.  At least one species of crustacean was found  at every
station sampled during September 1981.  Eight types of  crustaceans were
collected from Shirttail Branch; these included cladocerans, ostracods,
copepods, isopods, shrimp, and crayfish (Table 8.1.4-30).  A lesser
number of crustacean types was found at the other  stations.  A large
number of insect species was found at each station sampled.  Insect
orders represented in the collections included Collerabola (springtails),
Epheraeroptera (mayflies), Odonata (dragonflies and damself1ies),
Hemiptera (bugs), Lepidoptera (moths and butterflies),  Coleoptera
(beetles), Trichoptera (caddisflies), and Diptera  (flies  and
mosquitoes).

October 1981
Each of the eight stations sampled in October 1981 was  inhabited by  a
variety of epifaunal species (Table 8.1.4-31).  Oligochaete worms and
insects were the dominant groups, in terms of number of species,  at  all
stations.  Plunder Branch and Doe Branch were inhabited by the largest
variety of tubificid and naidid oligochaetes; the  central Horse  Creek
station produced only immature worms.  No molluscs were collected from
Brushy Creek 2 or Horse Creek Middle, while Doe Branch  samples contained
several species of bivalves and gastropods.  Crustaceans  were collected
at every station sampled during October 1981.  Crayfish were  found  at
                               8-21

-------
every station, araphipods were found at  five of  the eight  stations,  and
other crustacean groups were represented  at four  or  fewer stations.
Large numbers of insect species were collected  at most of the  stations
sampled during October 1981 (Table 8.1.4-31).   Insect orders  represented
included Collembola, Epheraeroptera, Odonata, Hemiptera, Coleoptera,
Trichoptera, Lepidoptera, and Diptera.  Each station had  its  own,
different insect community, composed of a unique  combination  of  species
belonging to these orders.  The community at each station was
established in response to a large number of abiotic and  biotic  factors
which combined to create a unique environment at  each location sampled.

February 1982
A presence/absence matrix of the invertebrate epifaunal taxa  collected
from the eight stations sampled during February 1982 is presented  in
Table 8.1.4-32.  As was the case during preceding sampling efforts,
naidid and tubificid oligochaetes and insects were the most abundant
groups represented.  The greatest number  of oligochaete species  was
found in Plunder Branch, while Horse Creek North  and Shirttail Branch
samples did not contain any oligochaetes.  Leeches were found  in Brushy
Creek, Doe Branch, and Horse Creek North.  Bivalve and gastropod
molluscs were found in Brushy Creek, Doe  Branch,  Horse Creek  Middle,
Plunder Branch, and Shirttail Branch.  At least one species of
crustacean was found at every station except Horse Creek  North.
Cladocera, copepods, isopods, araphipods,  and crayfish were the
crustacean groups represented in the February 1982 collections.  There
were more insect species collected at each station than species  of  any
other group.  Orders of insects represented in  the samples included
Collembola, Epheraeroptera, Odonata, Hemiptera,  Lepidoptera, Coleoptera,
Trichoptera, and Diptera.  There was a different  species  mix  at  each
station, established in response to the different environmental  factors
present.
                                8-22

-------
Hester-Dendy raultiplate samplers were submerged  in  July 1981  and
retrieved approximately 4 weeks  later in August  1981,  and  were  colonized
by a wide variety of organisms (Table 8.1.4-33).  Hester-Dendy  samplers
deployed at Brushy Creek were numerically  dominated by neraatodes  (44
percent).  Oligochates, principally naidids,  and  insects comprised  the
majority of the remaining taxa.  Samplers  placed  in Doe Branch  were
numerically dominated by insect  taxa (64 percent).   The dominant  insects
were the chironoraids, Polypedilum illinoense  (17.3  percent) and
Nembocera sp. (32.7 percent).  Naidid oligochaetes  comprised  an
additional 18 percent of the  fauna which colonized  the substrates.
Horse Creek samplers were dominated by naidid oligochaetes (71  percent),
particularly Haemonais waldvogeli (46.1 percent).   Insects, principally
chironomids, comprised an additional 23 percent  of  the organisms.   In
Plunder Branch the naidid oligochaete Bratislavia unidentata  accounted
for 58.4 percent of the organisms found on Hester-Dendy samplers;
insects, principally chironomids, accounted for  an  additional 25  percent
of the organisms.  Seven mollusc taxa were identified  from Plunder
Branch samplers.  Shirttail Branch samplers were  dominated by
Chironomus spp. and Dero vaga which accounted for 30.8 percent  and
20.5 percent of all organisms, respectively.

Hester-Dendy samplers were deployed in August 1981  and retrieved  in
September 1981 (Table 8.1.4-34).  Ninety-seven percent of  the fauna
which colonized the samplers  in  Brushy Creek  were oligochaetes.  These
were principally naidid species, with Dero trifida  accounting for
74.1 percent of all'organisms.   Doe Branch samplers were codorainated by
oligochaetes (45 percent) and insects (42  percent) .  Immature tubificids
were the most common oligochaete (31 percent), and  Chironomus sp.
(12 percent) and Nembocera sp. (12.4 percent) were  the roost common
insects.  Hester-Dendy samplers  in Horse Creek were colonized
predominantly by insect taxa  (73 percent), with  Chironomus spp.
.accounting for 47 percent.  Naidid oligochaetes  accounted  for an
additional 27 percent of the  organisms.  Plunder Branch samplers  were
dominated by _B. unidentata (66 percent) as in the previous sample

period.  Oligochaetes as a group comprised 79 percent of the organisms
on Plunder Branch Hester-Dendy samplers, and insects comprised
15 percent.  Thirty-three taxa colonized Hester-Dendy samplers in
Shirttail Branch.  No one taxa heavily dominated the collection; the
gastropods Laevapex sp. and Helisoma sp. were most common, equalling
19.4 percent and 17.7 percent of all organisms.

The final Hester-Dendy sampling period was from September 1981 to
October 1981 (Table 8.1.4-35).  The samplers placed  in Doe Branch were
colonized predominantly by insect taxa (83 percent), with the dominant
organism the ceratopogonid Palpomyia sp.  (40.4 percent).  Naidid
oligochaetes accounted for the remaining 17 percent of the organisms.
Samplers in Doe Branch were more evenly colonized with naidid
oligochaetes (23 percent), molluscs (13 percent), arachnids (8 percent),
crustaceans (4 percent), and insects (50 percent), and no one species
numerically dominated the collection.  Ninety-three percent of the
organisms which colonized Hester-Dendy samplers deployed in Horse Creek
were insects.  Chironomus spp. were the most prevalent, accounting for
57.3 percent of all organisms.  Naidid oligochaetes equalled 6 percent
of the organisms.  Plunder Branch samples were comprised of 70 percent
insects and 22 percent naidid oligochaetes.  Laevapex sp.
(21.4 percent) was again the most common animal on Hester-Dendy samplers
in Shirttail Branch.

Shannon-Weaver diversity calculated for Hester-Dendy collections ranged
from 1.54 to 4.45 over all sites and collections (Table 8.1.4-36).
Diversity was generally highest for samplers deployed from September
1981 to October 1981 which resulted primarily from an increase in
species richness.  The lowest value (1.54) recorded  for Brushy Creek in
August 1981 to September 1981 resulted from both low species richness
and low evenness components.

In February 1982, core and dipnet samples were collected in Mitchell
Hammock to provide baseline data on benthos of a "nonflowing" system.
                               8-24

-------
Sampling by both core and dipnet resulted in the collection of 92
benthic macroinvertebrate taxa (Table 8.1.4-37).  Dipnet samples
collected 82 of the total taxa, while core samples collected 46 of  the
total taxa.  Forty-five taxa were collected only in dipnets.  The number
of taxa per station ranged from 24 to 60.  Within Mitchell Hammock  as a
whole, Coleoptera, Diptera and Oligochaete were the dominant taxa
collected, representing 28.6 percent, 24.2 percent, and 17.6 percent,
respectively, of the total taxa collected.

Epifaunal invertebrates collected from the CF Hardee Phosphate
Complex II site were predominantly oligochaete worms, molluscs,
crustaceans, and insects.  The majority of the animals collected were
insects; tubificid and naidid oligochaetes formed the second most
abundant group found at most stations during most sampling trips.   Many
more epifaunal species were collected from each station than infaunal
species.  This diversity difference is to be expected, and is usually
due to the wide variety of habitat types available to epifauna.

8.1.4.5  FISH
Fish are an important component of freshwater ecosystems and ah integral
part of food webs.  They are consumers of phytoplankton and benthos and
serve as food for higher trophic levels, including birds and man.
Cyprinodontidae (killifishes and topminnows) and Centrarchidae
(sunfishes and basses) are the most important freshwater fish families
in Florida.  A comparatively large number of exotic species are
established in the state's waters, and there is significant penetration
of marine fishes into Florida's freshwater habitat.

At least 21 species cf fish and 2 species of amphibians were collected
on the CF Hardee Phosphate Complex II site between August 1981 and
February 1982 (Table 8.1.4-37).  Direct, quantitative comparisons
between stations and sampling trips cannot be made, due to the
relatively limited, qualitative sampling efforts.  In addition, all
stations were not sampled during each sampling trip due to water level
conditions.
                               8-25

-------
Most of Che fish collected belonged to one of  four  families.
Representatives of the Centrarchidae  included  several  species  of sunfish
(Elassoma evergladei, Everglades pygray sunfish; Lepomis macrochirus,
bluegill; L. marginatus, dollar sunfish; and L. punctatus,  spotted
sunfish), warraouth (Chaenobryttus gulosus), and largemouth  bass
(Micropterus salmoides).  Catfish species  collected  included  the native
brown and yellow bullheads (Ictalurus nebulosus and  I. natalis),  and  the
tadpole madtorn (Notorus gyrinus), as  well  as the  exotic walking  catfish
(Clarias batrachis).  Members of the  Poeciliidae, or livebearer  family,
found on the property included the sailfin molly  (Poecilia  latipinna),
mosquito fish (Gambusia affinis), and  least killifish (Heterandria
formosa).  The fourth family represented by.several  species was  the
killifish family, Cyprinodontidae.  The flagfish  (Jordanella  floridae),
 »
bluefin killifish (Lucania goodei), and a  killifish  (Fundulus  sp.),  are
members of the Cyprinodontidae family which were  collected  on  the site.

The fish species collected on the site can be  roughly  divided  into two
habitat-associated assemblages.  The  areas characterized by soft
bottoms, sluggish flow, dense aquatic vegetation, and  periodic low
dissolved oxygen are inhabited primarily by groups such as  the
livebearers.  These types, of fish are generally small  and find refuge in
                                 h
aquatic vegetation.  They are tolerant of  low  dissolved oxygen levels
and, because they are livebearers, their reproductive  success  is not
dependent upon substrate type.

The second habitat type is characterized by more  open, flowing water;
sandy bottoms; and fewer periods of low dissolved oxygen.   These  areas
favor the survival of the larger predatory species such as  centrarchids.
The greater flow in these water bodies leads to a more scoured,  sandy
bottom, which is conducive to nest building by egg-laying species.

8.1.5  SUMMARY
The aquatic communities on the CF Industries Hardee Phosphate Complex  II
site were examined between July 1981 and February  1982.  The communities
studied included phytoplankton, periphyton, benthic infauna, epifauna,
and fish.  Sampling stations were located in Horse Creek, Brushy Creek,
Shirttail Branch, Doe Branch, Plunder Branch, Coon's Bay Branch, and
Mitchell Hammock.

In areas of extensive marsh with intermittent flooding, rooted vascular
plants are the major primary producers and the importance of phytoplank-
ton is diminished.  However, periphyton and epifauna may attach to  the
plant stems and the substrate.  Several genera of diatoms were usually
the dominant or codominant algae in these shallow  areas.  Areas with
permanent water receiving organic loading were characterized by crypto-
phytes, chlorophytes, and euglenophytes.

Benthic infaunal populations were numerically dominated by a relatively
limited variety of organisms.  Tubificid oligochaetes, especially
Limnodrilus hoffmeisteri, were ubiquitous during all sampling periods.
Larval chironomids (midges) usually comprised the  remainder of the
samples.  Epifaunal populations contained more species than infaunal
populations, due to the wider diversity of habitats utilized by epi-
faunal organisms.  Major groups represented included naidid oligo-
chaetes, molluscs, crustaceans, and insects.  Several orders of insects
were normally represented in the epifauna of each station.  Dipterans
were usually the most numerous insects collected.

Most of the fish species collected belonged to the sun fish, catfish,
livebearer, and killifish families.  Areas characterized by soft
bottoms, sluggish flow, dense aquatic vegetation, and periodic low
dissolved oxygen were inhabited primarily by the smaller livebearers and
killifish.  Areas with more open, flowing water; sandy bottoms; and
fewer periods of low dissolved oxygen were inhabited by larger,
predatory forms such as sunfish.

                     9.1  THE AFFECTED ENVIRONMENT

9.1.1  REGIONAL DESCRIPTION
The CF Hardee Phosphate Complex II site, located in the northwestern
quarter of Hardee County, occurs within the coastal lowland ecoregion  of
the Beech-Sweetgum-Magnolia-Pine-Oak Province of Peninsular Florida
(Bailey, 1976).  The vegetative pattern in the region can be  character-
ized as temperate/sub-tropical plant associations.  Their distribution,
community structure, and species composition are influenced by  intrinsic
biological interactions  and various topographic, edaphic, hydrologic,
geologic, and climatic  factors.

A  general description  of the  land  use  and  cover  types  occurring in the
site region  is  presented in the Central Florida  Phosphate Industry Area-
wide Impact  Assessment (U.S.  Environmental Protection  Agency, 1977).
The  study encompassed  a seven-county area  of western Peninsular Florida,
including Hardee County.  Five major plant community types  were
described for  the  region:
      1.  Agricultural  Land—including  cropland,  pasture,  orchards,
         citrus groves, nurseries,  parklands  for recreation,  and old
          fields;
     2.  Rangeland—including herbaceous  rangeland, shrub and brush
         •rangeland,  and mixed rangeland;
      3.  Forest Uplands—consisting of oak hammocks, pine flatwoods,
          scrubby flatwoods or oak scrub,  sandhill, and sand pine scrub;
      4.  Wetlands—including wooded wetlands  (mixed hardwood swamp,
          cypress swamp, bayhead,  shrub swamp)  and nonwooded wetlands
          (wet  prairie, deep freshwater marsh,  salt marsh, artificially
          created marsh); and
      5.   Water—inclvding lakes',  ponds, borrow pits, stock ponds,
          canals, and streams.

 All of the  five major  plant community types outlined in  the  Central
 Florida Phosphate Industry Areawide Impact Assessment occur  on  and in
                                 9-1

 the  immediate vicinity of  the  site.   Citrus grove is the dominant agri-
 cultural  land use  north  of the site;  however,  only 2.6 acres of citrus
 grove occur on  the  site  proper.   The  rest of the land adjacent to the
 site  is predominantly palmetto rangeland and pine flatwoods.  Topo-
 graphic relief  to  these  relatively  flat  uplands is provided by natural
 creeks.   Major  wetlands  and  hardwood  hammocks  occur along creek drain-
 ages  both on and off the site.  The only vegetation associations which
 do not occur onsite and  are  rare or nonexistent within the immediate
 vicinity  of the site are sandhill,  sand  pine scrub, cypress swamp, and
 salt  marsh.

 9.L.2  SITE-SPECIFIC DESCRIPTION.
 9.1.2.1  VEGETATION AND WILDLIFE
 The CF Industries Hardee Phosphate Complex II  mine site property is
 located south of State Road  (SR)  62 near Fort  Green Springs in the
 northwestern quarter of Hardee County and occupies an area approximately
 10 miles by 2.5 miles.  The  14,994.0-acre site extends from Horse Creek
 on the west to Coon's Bay  Branch on the  east.

 Vegetation within the CF Hardee  Phosphate Complex II site generally is
 typical of regional plant  community types.   The property consists of
 wetland and upland associations,  most  of which have been altered by
 logging,  fire, draining, and other agricultural practices.  Currently,
 the proposed mine site is  predominantly  managed for cattle (fire main-
 tenance, grass seeding and combining,  and cattle rotation).  Wetland/
 floodplain complexes exist along  eight major on-site drainages (i.e.,
 Horse Creek, Brushy Creek, Shirttail  Branch, Doe Branch, Plunder Branch,
 Coon's Bay Branch,  Lettis  Creek,  and  Troublesome Creek), and one minor
 on-site drainage (Gum Swamp  Branch).   A  tenth  minor drainage area on the
 CF mine site,  Hog Branch,  drains  to the  east by overland sheet flow
 through pine flatwoods and palmetto rangeland.

Vegetation within the site has been separated  into nine major groupings
 based upon the Florida Land Use  and Cover Classification System
 (FLUCCS),  1976.   Table 9.1.2-1 provides  the  FLUCCS Level III legend,
 acreages,  and  percentages  for  the CF mine site vegetation map.  The
vegetation map (see Figure 9.1-1) is  divided into  both eastern and
western portions by the Seaboard  Coast Line  Railroad.   A plant species

 inventory of the site by plant community  type  is  presented in
 Table 9.1.2-2.  Taxonoraic  identification  of  plant  species  follows that
 of Wunderlin (1982).  Plant species  identified  during  the  botanical
 investigations by Dames and Moore (CF DRI, 1976) which were not observed
 during the latest surveys  (i.e., 1981 to  1982)  were  taxonoraicaily
 updated and included in the plant species  inventory  table.

 The wildlife composition of an area  is ultimately  determined  by the
 natural resources available within it.  These resources make  up a life
 support system for  a given species requirement.  Basic  requirements for
 survival of a wildlife species include an adequate supply  of  food,
 water,  shelter from predators  and varying climatic conditions  and
 resources to successfully breed and rear offspring.

 The CF  Hardee Phosphate  Complex II site is located within a region  that
 is  characterized  by a climate  of widely ranging temperatures  and high
 rainfall,  nearly  level  topography resulting in large or numerous areas
 of  water drainage and retention (wetlands), and complex soil  structure
 and  plant  community  composition.   These  combined factors produce
 suitable habitat  for a diverse composition of wildlife species
 represented  by amphibians,  reptiles,  birds,  and mammals.

 A particular  animal's habitat  is  usually considered in terms of the
 plant community in which  it is  found.  Many animals have life require-
 ments that  are not satisfied by a single plant community.   An animal's
 mobility enables it  to move to  numerous  communities until  its needs are
 met.  Some  animals spend much  time on the  edge of  two adjacent and
 different communities (ecotones)  where they benefit from resources found
 in both.  To describe the habitat utilized by each  animal  occurring on
 the CF mine site property would be a  very  complex  presentation.
 Instead, a discussion of the major plant communities  is provided,
 including the important faunal  species found  in  each.   Tables 9.1.2-3
 through 9.1.2-5 list  the fauna  known  or  expected to occur  on the CF mine
site property and the major plant communities  utilized  by  each.

-------
Field surveys were conducted in August to September  1981  and  February to
May 1982 for vegetation, and in August to September  1981  and  February
1982 for wildlife.  Information also was taken  from  the CF  DR1  (1976)
field investigations.

Row Crops—211
A small open field (13.1 acres) situated along  the  northern property
boundary has been planted with truck crops.   Crops  within this  field are
rotated and can, during the appropriate season,  consist  of  corn,  tomato,
watermelon, cucumber, green pepper, or strawberry.   Depending upon the
amount of maintenance, the cultivated  field  could provide some  cover for
small animals.  Newly sown and mature crops  also could provide  a  food
resource for urban-adapted small mammals (e.g.,  squirrels,  rabbits)  and
passerine birds (e.g., Common and Boat-tailed Crackle, Common Crow).

Field Crops—212
A single tract of land (44.1 acres) on a western portion  of the site has
been fenced off and cultivated in millet, sunflower,  and  sorghum.   The
management objective  for the cultivated field was to  establish  a  grain
crop for local game birds such as doves and  quail.  Ground  Dove,
Mourning Dove, Red-winged Blackbirds and Boat-tailed  Crackles were
observed feeding in the field.  Although cultivated  land  such as  the
grain field on the property is similar to improved  pasture  (i.e.,  both
are maintained in an early successional state),  the vegetation  usually
is higher and gives more wildlife cover.

Improved Pasture—213
Approximately 1,310.3 acres (or 8.74 percent) of the  site is  composed of
improved pasture.  Improved pastures consist  of  native pine flatwoods
that have been cleared of all vegetative strata  and  seeded  with grasses
(bahia grass, rye) and legumes (white clover, Korean  clover,  prairie
clover)  for cattle.  Pastures are maintained  through  fertilization,
cattle rotation and seeding/combining operations.   Pasture  land has  a
low degree of physical structure, a single level of  herbaceous  vegeta-
tion, and does not support a high diversity  of wildlife.  The pasture
habitat provides little cover for large animals  such  as  white-tailed
                                 9-39

-------
deer,  gray  fox,  wildhog,  and bobcat.  However, these mammals may use
pasture  edges  close to the cover of forested areas.  Armadillos and
raccoons  are often found  digging and scavenging in improved pastures.
Small  mammals  trapped in  pastures include the house mouse, cotton mouse
and  cotton  rat which become prey for such raptors as Red-shouldered and
Red-tailed  Hawks,  American Kestrel,  and Marsh Hawk.  Other birds using
pasture  lands  include Loggerhead Shrike, Eastern Meadowlark, Boat-tailed
Crackle,  Red-winged Blackbird,  Carolina Wren, White-eyed Vireo, Yellow-
throated  Warbler  and Common Yeilowthroat.  Cattle Egrets feed in
pastures, and  when pastures are flooded, other colonial waterbirds may
be seen where  food sources  are  concentrated.   These include herons,
egrets, White  Ibises,  Woodstorks and Sandhill Cranes.  Black and Turkey
Vultures  are carrion eaters and scavenge over pastures as well as every
other  terrestrial  community on  the  site.

Orange Grove—231
Only one  citrus grove  of  approximately 2.6 acres is present on the site
proper.  The citrus  grove,  which is  of a sweet orange variety, is well
maintained  and exhibits a low structural diversity.  Although wildlife
usage  is  limited,  a  few frequent visitors to  citrus grove habitat
include gray and  fox squirrel,  Northern Cardinal,  Blue Jay, and Mocking-
bird.

Palmetto Prairies  or Palmetto Rangeland—321
Palmetto  rangeland  is  the dominant plant community on the CF mine site,
encompassing 46.4  percent of the total area   (6,957.2 acres).   Palmetto
rangeland was  pine  flatwoods before  the land  was  logged and cattle were
introduced.  Palmetto  rangeland is characterized  by a conspicuous dense
shrub  layer of saw  palmetto.  Although rangeland  has  no true understory
or overstory tree  stratum,  a few remnant pines  are scattered throughout
the association.   Scattered woody shrub associates include  sand live
oak,  gallberry, and  wax-myrtle.   A yearly fire  management program opens
shrub layers and promotes a proliferation of  indigenous herb species
(wiregrasses, broomsedges,  and  composites).
                                 9-40

-------
 The  saw palmetto  shrub  layer provides good cover for numerous upland
 dwellers.   Palmetto  berries and seeds produced by the herbaceous vegeta-
 tion supply food  for herbivores and granivores.  Common mammals of
 rangeland  include the cotton rat, cotton mouse, armadillo, raccoon,
 opossum, and  eastern cottontail.   Larger mammals include wild hog,
 white-tailed  deer and predators such as bobcat and gray fox.  Several
 bird species  common  to  rangeland  are Mourning Dove,  Ground Dove,
 Bobwhite Quail, Common  Nighthawk, Western Kingbird,  Great-crested
 Flycatcher, Carolina Wren,  Rufous-sided Towhee, Mockingbird, American
 Robin,  and  both Palm and  Pine Warblers.

 Predator species  include  the Red-shouldered Hawk, American Kestrel, and
 Loggerhead  Shrike.   Amphibians and reptiles commonly encountered include
 oak  toad, green anole,  six-lined  racerunner, black racer, and gopher
 tortoise.   Gopher tortoise  are usually found in dryer, well-drained
 sites.

 Pine Flatwoods—411
 Large tracts  of pine flatwoods are distributed along the northern areas
 of the  property (732.7  acres or 4.89 percent).  Pine flatwoods are open
 to dense woods dominated  by an overstory of pines.  Longleaf pine occurs
 on the  drier  sites;  slash pine is frequently found along wetter areas.
 Shrub layers  are  dominated  by thick saw palmetto and other associated
 woody taxa  (e.g., gailberry,  wax-myrtle,  sand live oak).  In the absence
 of fire, woody plants form  an understory layer.  Pine flatwoods on the
 property are  remnant  associations that  most probably were left as a seed
 source  to the surrounding,  logged flatwoods (i.e.,  rangeland).

Rangeland,  therefore, is a modified  form  of pine  flatwood with the
canopy  species of longleaf  pine and  slash pine removed.   Ground cover
and shrub vegetation composition  is  much  the  same  in  both communities.
Therefore,  wildlife resources  discussed  for the palmetto rangeland are
generally similar for pine  flatwoods.  However,  pine  flatwoods differ
                                 9-41

-------
by the presence of a pine canopy  and  a  woody  understory.   There  is  more
vegetative cover  for wildlife within  the  flatwoods,  and  the  addition of
vegetative strata (i.e., canopy,  understory)  allows  for  greater  niche
and species diversity.  The occurrence  of woodpeckers,  for instance, is
much more indicative of a forested  flatwoods.

Woodpeckers present in the  flatwoods  are  represented by  the  Red-bellied,
Pileated, Red-headed, Hairy and Downy Woodpeckers, Common  Flicker  and
Yellow-bellied Sapsucker.  The endangered Red-cockaded Woodpecker
inhabits pine flatwoods, but has  specific requirements  for nesting  and
roostiag.  The pine flatwoods on-site were searched  for  Red-cockaded
Woodpecker evidence, and none was  found.

Other Hardwoods or Oak Hammocks—422
Less than 16 percent (2,354.0 acres)  of the site  supports  hardwood
hammock.  Hardwood forests on the  property have  a dominant tree  crown of
oaks.  Oak hammocks usually encircle  wetland  associations  or fringe
drainage channels on the property.  Hammocks  occur on well-drained
upland sites to poorly drained lowland  areas  with thin organic  soil
layers.  Overstory vegetation is  usually  indicative  of hydric  and
edaphic conditions.  Xeric, live  oak-dominated  forests with  well-
developed saw palmetto layers are  found along dry highlands  and  usually
occur on the same elevations/soils  as palmetto  rangeland.  Mesic  laurel
oak/cabbage palm associations usually occur along slightly lower
elevations adjacent to wetlands and are flooded  for  short  periods  of
time during high rainfall events.   Hydric,  laurel oak-dominated  areas
(bottomland hardwoods) occur within drainage  lowlands and  are  seasonally
inundated.  Other arboreal associates of  the  bottomland  hardwoods
community are elm, pop ash, tupelo, hackberry,  sweetgum, and maple.
Although FUJCCS recognizes all oak-dominated  communities as  uplands,
bottomland hardwoods are considered to  be a freshwater  swamp type  in
other vegetation classification schemes (COE, 1977).

In climax or near climax hammocks,  the  canopy cover  (primarily oak
species) intercepts  light and  limits  development of  vegetation in the
                                  9-42

-------
shrub and herbaceous layers.  Hammocks with sparse understory  develop-
ment provide little cover or  food  for ground  and  shrub  dwelling fauna.
The sa.ne effect is felt in hammocks that have been overgrazed  by cattle.
In these hammocks most wildlife utilize edge  areas where  light penetra-
tion is greater.

Mast production from oak species  is high and  is  an  important resource
for white-tailed deer, wild hog,  eastern gray squirrel,  southern flying
squirrel, Wild Turkey and Bobwhite Quail.  The  tree  component  is especi-
ally important to birdlife including Common Flicker,  Red-bellied
Woodpecker, Pileated Woodpecker, Yellow-billed Cuckoo,  Barred  Owl and
numerous passerine (perching) species.  Passerines observed in the
hammock communities include Blue  Jay, Carolina Chickadee, Tufted
Titmouse, Carolina Wren, Mockingbird, Catbird, White-eyed Vireo, Yellow-
throated Warbler, Parula Warbler,  Common Yellowthroat and Rufous-sided
Towhee.

Heavy accumulations of leaf litter, tree stumps  and  downed trunks
provide excellent cover for small mammals  including  cotton mouse and
golden mouse.  This habitat is also used by herpetofauna  including oak
toad, southern leopard frog,  ground skink, black racer,  corn snake,
yellow rat snake, and Florida box  turtle.

Freshwater Swamp—621
The swamp community represents approximately  8.27 percent (1,240.4
acres) of the CF property area.   Freshwater swamps  are  forested wetlands
which are dominated by water  tolerant hardwoods.   Arboreal overstory and
understory components of freshwater swamps include  either single
dominant or mixed assemblages of  red maple, water tupelo, pop  ash, sweet
bay, swamp red bay, loblolly  bay,  dahoon holly,  and  elm.   Hardwood
swamps usually have deep organic  layers and hold stagnant water for long
periods of time.  Included in this category are  shrub swamps.   Shrub
swamps are young serai stages leading to the  formation  of hardwood
swamps.  Buttonbush, red maple, and willow form  monotypic stands,
usually in association with freshwater marshes  and  tree swamps.  The
                                 9-43

-------
mature  swamp  is  similar  in  structure to the hardwood hammock,  and there
is much overlap  in  faunal  species composition.   Passerine birds observed
in mature  swamps (in  addition  to  those of the hammock communities) were
Yellow-breasted  Chat,  Prothonotary Warbler, Northern Cardinal, Blue-gray
Gnatcatcher and  Summer Tanager.   The hydrologic aspect of the  swamp
provides an additional dimension  not found in the hammock.   Swamps
provide a  moderated climate  in terms of temperature and moisture.
During  the dry season  the  swamp  acts as a sink, attracting  numerous
wildlife species  as other water  sources become  unavailable.   Swamps
provide year-round habitat  for many amphibians  and reptiles  including
eastern narrowraouth toad; barking,  green and  squirrel treefrogs;  Florida
chorus  frog; Florida  cricket  frog;  southern leopard frog; American
alligator; Florida mud turtle; Florida red-bellied turtle;  water  snakes
of the  genus Nerodia;  eastern  indigo snake; and Florida cottonmouth.
Wild hog,  raccoon, armadillo,  gray  squirrel,  and white-tailed  deer were
frequently observed within the swamps  on-site.   An Eastern  wood rat den
was discovered in a maple/tupelo  swamp within Mitchell Hammock.

Shrub swamps lack canopy development and associated canopy-dwelling
wildlife.  Shrub swamps on the CF mine site were judged suitable  for
colonial wading  bird roosting  and nesting,  but  no rookeries  were  found.

Freshwater Marshes—641
Total area of freshwater marsh on the  site equals nearly 2,339.6  acres
(15.6 percent).  Freshwater marshes  are usually circular (highland
depressions) to  oblong (drainage  lowlands), herb-dominated wetlands.
Maideucane, sawgrass,   pickerelweed,  common  flag,  and  wapato  are some  of
the deep water marsh associates.  Herbs such  as cordgrass,  soft rush,
broomsedge and iris may form transitional,  outer fringes to  the deep
water areas.  Marshes  protected  from fire  during the  dry seasons  may
have scattered shrub (buttonbush, willow)  and tree species (tupelo, red
maple) throughout.
                               9-44

-------
The marshes vary in depth, plant composition, and amount  of  open  water.
The larger marshes normally have more developed  zonation  and support a
diversity of wildlife.  Most mammals of the marsh system,  such  as
raccoon, armadillo, rodents, marsh and eastern cottontail rabbits, wild
hog, fox and bobcat, utilize the shallow edge zones  feeding  on  crayfish,
insects, vegetation or other animals.  Some marshes  support  the round-
tailed muskrat which uses deeper pool areas where it  builds  nests and
feeding platforms.  Marshes also support several species  of  frogs and
snakes and, occasionally, turtles and alligators.   The  freshwater marsh
is a very productive system and is an important  food  resource for wading
birds.  Waders commonly seen using marshes are Great  Blue Heron,  Little
Blue Heron, Green Heron, Snowy Egret, Great Egret and White  Ibis.  Up to
800 White Ibises were seen in one feeding congregation.   Other  birds
using the marsh system include Sandhill Crane, Greater  and Lesser
Yellowlegs, American and Least Bittern,  Spotted  Sandpiper  and Long-
billed Dowitcher.  Tree swallows were often observed  feeding on insects
over the marsh, and shrubby marsh edges provide  habitat for  Common and
Boat-tailed Crackles, Red-winged Blackbirds and  several other passerine
species.

Ruderal Land
Ruderal lands on the property comprise an extremely  small percentage of
disturbed upland, wetland, and permanent water bodies,  including  borrow
pits (stock ponds), unimproved roads, maintained drainage ditches, rail-
road perimeters, fence rows, and transmission line corridors.  Since the
ruderal land component of the CF mine site was considered a  minor part
of the land use on-site, the areas of disturbance were  not delineated on
the vegetation map by a separate land use category.   Ruderal lands,
therefore, are incorporated into the major cover classification in which
they are situated.

Disturbed upland sites exhibit low structural diversity and  high species
diversity.  Opportunistic, herb taxa usually dominate ruderal lands and
are able to survive in a variety of  soil types.   Typical  upland ruderal
plants include dropseed, Caesar's weed, beggar-tick,  broomsedge,  and
                                9-45

-------
dog fennel.  The borrow pits/stock  ponds  on  the  property support
permanent water and may be dominated  by  floating aquatics such as float-
ing hearts, frogs-bit, and duckweed.  These  altered  habitats  support
wildlife associated with early  successional  communities  such  as pasture
and cropland (previously described).  Fauna  inhabiting ruderal land  may
be complemented by species of adjacent communities.   This concept is
illustrated when a transmission corridor  intersects  a wooded  swamp or
other dissimilar community.  Borrow pits  on  the  site have been excavated
for elevating roadbeds.  The resultant flooded depressions  are used  for
watering cattle and provide habitat for  the  American alligator, Florida
snapping turtle, peninsula cooter,  Florida red-bellied turtle and
Florida softshell turtle.  These  aquatic  resources may provide
concentrations of food for wading birds  and  other wildlife.

9.1.2.2  WETLAND/DRAINAGE UNIT  DESCRIPTIONS
Portions of ten drainage basins are present  on the Hardee Phosphate
Complex II site.  Six of these  basins (Horse Creek,  Brushy Creek,
Shirttail Branch, Doe Branch, Plunder Branch, and Coon's Bay  Branch)
have defined stream or channel  systems on the site.   Lettis Creek and
Troublesome Creek have poorly defined drainages  on-site, representing
the upper end of their respective watersheds.  Small portions of the Gum
Swamp Branch and Hog Branch drainages are also present on-site.

Each drainage basin on-site was qualitatively surveyed to validate and
supplement 'the existing data base and accurately characterize conditions
and functions of each area.  Information  from these  surveys also was
used to identify structural breakpoints  in the drainage  systems and
divide the basins into the wetland/drainage  study units
(Figure 9.1-2).

The results of these survey efforts were  used to develop the  following
descriptions of the delineated wetland/drainage  units.
                                 9-46

Horse Creek
Horse Creek, an intermittent strearacourse, originates  approximately  3.6
river miles upstream from the site, and joins  the Peace  River,  approxi-
mately 40 river miles downstream.  On-site,  the drainage  basin  supports
the main channel with associated laurel oak  floodplain,  secondary
channels with connections to swamps, and  isolated,  perched maidencane
marshes located within higher pine-palmetto  rangeland.   The main channel
on-site was divided  into four drainage units (H1-H4).

Drainage Unit HI consists mostly of laurel oak floodplain  interspersed
with numerous, small wetland depressions  «1 acres,  collectively)  which
have no recognizable channel connection to Horse Creek.   Depressions
within the  floodplain were dominated by maple, tupelo,  and/or  pop  ash.
One small, maple swamp (1.0 acres) is contiguous to  the  main channel in
HI.  Two hardwood swamps (16.3 acres) within HI connect  to the  Horse
Creek channel via secondary channels off  of  the property.  A large
central marsh (18.3 acres), dominated by  a mixed assemblage of  maiden-
cane, pickerelweed, galingale, and buttonbush, is contiguous to  the
Horse Creek channel within Drainage Unit  H2.   Drainage  Units H3 and  H4
are distinct from one another due to an upland oak hammock; however,
they are connected downstream at the H3-H4/H2  interface  by contiguous
wetland vegetation.  Drainage Unit H3 supports a continuation of the
main channel and a branched secondary channel.  Drainage Unit H4
contains a manmade ditch and 6.7 acres of maple/willow  swamp.

Drainage units (H5-H8) mainly support isolated marshes  of maidencane and
pickerelweed situated within upland, pine-palmetto  rangeland.   One other
minor drainage area of Horse Creek (H9),  situated at  the  extreme
northwest corner of the property, supports approximately 17.3 acres  of
isolated marshes.
                                9-48

-------
Brushy Creek
The Brushy Creek system consists primarily  of  the  three  Mitchell Hammock
units (B4, B5, and B6) and a Y-shaped,  second  major  headwater wetland
(B2) which have channels converging  into  a  large hardwood  swamp complex
(Bl) to form the upper end of Brushy Creek.

Brushy Creek below this convergence  consists of a  poorly defined channel
through a hardwoods-dominated floodplain, grading  from  red  maple and pop
ash at the upper end through a red maple/tupelo swamp.   A very young pop
ash-willow swamp covers the floodplain  south of a  dirt  road which
crosses the channel.

The wetland area (173.2 acres) of Unit  B2 consists of a highly diverse
system containing all ten of the associations  found  in  Mitchell Hammock
(i.e., oak, maple/tupelo, willow, buttonbush,  pop  ash,  maidencane,
maidencane/soft rush, broorasedge/soft rush,  sawgrass and pickerelweed/
flag).  Stands of mature laurel oak  floodplain forest and  pop ash swamps
occur in the north end, grading into red maple swamp and sawgrass/
maidencane marshes at the south end.  With  the exception of the flood-
plain forest area, the woody vegetation is  relatively young in this unit
with few trees with Diameter Breast  Height  (DBH) values in excess of
6-inches.  Although no bird nests were  noted,  the  pop ash/buttonbush
swamp in the north has most of the characteristics required for a
suitable rookery area during high water periods.

Units B4 and B5 in Mitchell Hammock  are dominated  by maidencane marshes
ringed with oak hammock.  A raaple/tupelo  swamp also  occurs  on the north
side of Unit B5.  Unit B6 contains a large,  mature raaple/tupelo swamp on
the north.  This swamp is an exceptionally  well developed  mature system
with large trees and diverse herbaceous and shrub  strata.
                                9-49

-------
Other units of the Brushy Creek system  (B3,  B7,  B8,  B9)  consist of
largely isolated raaidencane marshes or  red maple shrub  swamps with
combined wetland acreages of 248.5 acres.

Shirttail Branch
Shirttail Branch is the only drainage in  the  west  pasture  that has a
northerly flow.  The most downstream unit, SI,  consists  of a  defined
channel through a narrow laurel oak hammock.   In Unit S2,  the channel
area flows into a broad floodplain bottomland  hardwoods  community
dominated by laurel oak, elm, pop ash,  and tupelo.   Units  S3  and S4
consist of maple shrub swamps.  Upstream  of  Unit S4  are  several maiden-
cane and sawgrass marshes and maple swamps in plateau depressional areas
(Units S5 and S6).  Shirttail Branch has  a total of  343.7  acres of
forested and non-forested wetlands.

Doe Branch
Doe Branch represents the largest and most complex drainage system on-
site.  The Doe Branch drainage basin was  divided into  14 drainage units.
Western drainage units, D12 and Dll, drain into D3.  The most south-
western drainage unit, D14, is isolated from  the rest of the  Doe Branch
system by the Seaboard Coast Line Railroad tracks  and palmetto rangeland
but may still drain via pipe or by overland  flow during  peak  rainfall
periods into D12.  Two maple swamps (25.5 acres)  within  D12 function as
a subsidiary headwater to Doe Branch.   An incised  channel  connects the
two swamps to a 24.1- acre maple/bay swamp within Dll.   A  channel from
the Dll swamp cuts through hardwood forest and  connects  to the D3
drainage unit.  Central and eastern drainage  units also  converge within
the D3 drainage unit.  Drainage Units D9, D10,  and D13  form the central
drainage region.  The central branch begins  within maidencane marsh
willow swamp/maple swamp headwaters (D10) which connect  via channel to
wetland units within D9 (13.3 acres of  maple  swamp).

Drainage Unit D13 supports scattered bay  and  maple swamps  which drain
into D9.  At the interface of D9 and D3,  the  incised channel  widens into
                                      9-50

-------
a bottomland hardwoods.  The eastern Doe Branch drainage  stem  consists
of five drainage units (D4-D8) which also  converge within D3.   Drainage
Unit D6 contains headwaters/wetland units  for  the Doe  Branch system.  A
108.5-acre maple swamp drains directly  into D4  from  the D6 drainage
unit.

The D4 wetlands (217.7 acres) consist mostly of interspersed maidencane/
pickerelweed marshes and maple swamp.   Drainage Units  D5, D7,  and  D8
connect either directly by channel or marginally by  overland  flow  to  DA.
D4 then is directly connected to D3 via an incised channel.  Drainage
Unit D3 consists primarily of incised channels  situated within oak
hammock.  Channels emanating from the three drainage branches  join
within D3 and empty into the Dl drainage unit.  The  major wetland  unit
within Dl is a pop ash swamp (80.5 acres).  This wetland  unit  continues
off the property (Dl), eventually channelizes,  and connects  to Payne
Creek.

Plunder Branch
Plunder Branch is a complex drainage system consisting of numerous
marshes and swamps which are interconnected by  sand-bottom channels.
Offsite, to the north (1.3 river miles), the creek ultimately  joins with
Payne Creek, while on-site the creek splits into a western fork (1.6
river miles) and an eastern fork (2.3 river miles).  The  Plunder Branch
basin was divided into two offsite (Pla, Plb)  and six  on-site  drainage
units (PI, P2, P3, P4, P5, P6).  The western fork (P3, P2) and the
eastern fork (P6, P5, P4) converge at Pi with  P3 and P6 containing the
headwaters  for the Plunder Branch System.  The  combined drainage wetland
area of the two forks and the PI drainage  unit  is 552.6 acres;
32 percent  in the western fork, 64 percent in  the eastern fork and
4 percent in the PI drainage unit.

Within Unit P3, laurel oak hammocks encircle two maple/tupelo  headwater
swamps.  In the surrounding basin, numerous maidencane marshes within
upland rangeland contribute runoff to the  main channel either  directly,
                                   9-51

-------
through secondary channels, or  indirectly  through  ephemeral  ditches.
The main channel oasses  through  rangeland,  flatwoods and  oak hammock
into the drainage unit of P2 which contains  scattered  marshes.   The P2
drainage unit mainly  supports a  maple/tupelo swamp (27.7  acres)  and is
supplemented with 48.7 acres of  isolated wetlands  in the  rest  of the
drainage unit.

Entering the PI drainage unit from P2,  the  western fork joins  with the
eastern fork channel within the  PI drainage  unit.

Headwaters of the eastern fork begin  in  a  large  maidencane/arrowhead
marsh (Hammock Pond) within Drainage  Unit  P6.  Hammock Pond
(95.3 acres) within Unit P6, had recently  burned and was  dry during the
survey.  Isolated marshes (50.6  acres)  are  again the prevalent wetlands
of the P6 drainage unit  rangeland.

A few upper elevational marshes  (11.5 acres)  connect to the  P5 channel
before the channel reaches P4.   P4 contains  three  pop  ash  swamps (26.8
acres) that are directly associated with the  creek.

Finally, the channel exits into  PI and joins  the western  fork  channel.
A 9.9-acre mixed hardwood swamp  occurs  along  the western  edge  of both
channels within the PI unit.  The mixed hardwood swamp exhibits  a high
species diversity within the overstory (pop  ash, sweet bay,  elm, swamp
red bay, red maple, tupelo).  Mature  overstory trees (12  to  18 inches
DBH) reached heights of 45 feet  or more.   The  freshwater  swamp possessed
deep organic layers Olm) and was wet throughout.

Coon's Bay Branch
Coon's Ray Branch is a third-order intermittent  streamcourse,  which
drains south to north, ultimately connecting  to  Payne  Creek.   Coon's  Bay
Branch has headwaters within the extreme northeastern  corner of  the CF
Hardee Phosphate Complex II mine site.  Within the  south  pasture,  Coon's
Bay Branch was divided into four major drainage  units  (C4,  C3, C2,
and Cl).
                                 9-52

-------
The 20.8-acre hardwood swamp  in Unit  C3  is  the  main wetland headwaters
for the Coon's Bay Branch  system.  This  forested  wetland is dominated by
mature maples (LO to  13  inches DBH) which exhibit  an 80- to 100-percent
canopy coverage.  Other  overstory  associates  include tupelo, sweet bay,
and laurel oak, in order of magnitude.   Understory and  shrub species
consist of wax-myrtle, buttonbush, dahoon holly,  stiff  Cornell, southern
elderberry, water willow,  and swamp blueberry,  situated upon raised
hummocks (50 to 57.5  cm).  The ground stratum contains  a 0- (heavy maple
litter) to 100-percent herb cover  (lizard's  tail,  royal fern,  false
nettle, arum, and maple  seedlings).   Unit C3  also  supports a less mature
(4 to 8 inches DBH) and  drier segment of the  C3 headwater unit.  A
channel traverses the central portion of the  swamp and  a manmade ditch
skirts the eastern swamp/citrus grove perimeter.   The ditch and central
channel both join a natural channel,  situated within a mesic oak hammock
(C2).  Mature tupelo, as well as tree and shrub seedlings (stiff
Cornell, buttonbush)  were  frequent within the C2  conveyance.  The deeply
incised channel within C2 meanders through  the  forest and exits into
another maple/tupelo  swamp.  This  hardwood  swamp  exhibits similar
species composition to Unit C3, except for  an open canopy,  a dense shrub
layer, and a contiguous marsh edge.   From the swamp exit, a 183m-long
channel crosses a wet field (Unit Cl).   Within  Unit  Cl,  the channel
skirts a palmetto/bayhead edge and then  cuts  through a  dense palmetto
layer.  Another channel branches east  from  the  main  channel and dead
ends into a bayhead, while the main channel exits  at CR 62.

The C4 drainage unit within site boundaries supports two  small,  isolated
marshes (2.4 acres) in palmetto rangeland.  Offsite, the  C4 drainage
unit contains the main stream channel  with  associated hardwood  swamp.

Lettis Creek
Lettis Creek is a poorly defined drainage measuring  less  than one river
mile on-site and with an estimated wetlands area of  260.2 acres on-site.

Lettis Creek begins in a 78.6-acre marsh/swamp  unit (L4)  containing
sawgrass grading through buttonbush and  willow  into a young red maple
                                      9-53

-------
shrub swamp.  The major community  in L3  is  a bottomland hardwood
community dominated  by  laurel  oak  and red maple.   Small pop ash shrub
swamps also occur along the  primary  drainage,  as  a small  channel leaves
the hardwood community, and  enters  pop ash  and red maple  shrub swamp
complexes in Units Ll and L2.

Troublesome Creek
The Troublesome Creek system oil-site is  represented by four .small units
encompassing a total of 164.6  acres  of wetlands.   There is  no well
defined channel on-site.  Unit T5 consists  of  several small maidencane-
dominated marshes connected  by the Seaboard Coast Line Railroad tracks
along the Fort Green-Ona Road* These have  a very poorly  defined
drainage into a maidencane/buttonbush marsh in Unit T4 which extends
offsite to the south.  Wetlands in Units  Tl and T2 consist  of red maple
shrub swamp and maidencane marsh which also extends offsite.  Drainage
Unit Tl consists of  two separate drainage areas on the property.  One
area is located with the other drainage  units  of  Troublesome Creek (Tl,
T2, T4, and T5), while the other is  at the  extreme southeast corner of
the property.  A drainage unit initially  designated "T3"  has sub-
sequently been incorporated  into Drainage Unit D10 and is not described
here.  The southeast drainage  area of Tl  supports approximately 16.3
acres (i.e., collectively) of  isolated marshes.   Approximately 4.6 acres
of wetlands (marsh/swamp), however,  compose the northern  tip of Reaphook
Swamp, a large wetland complex located off  the site.

Gum Swamp Branch
Three small separate drainage  areas  (Gl,  G2,  and  G3),  located along the
northwestern edge of the property, drain  northerly into Gum Swamp
Branch.  Approximately 23.5  acres of maidencane marshes are isolated
within these drainage areas.  No well-defined  channel  extends from the
drainage areas offsite.
                              9-54

-------
Hog Branch
Two small areas situated along the extreme eastern  property  boundary
drain by overland flow to the east.  These two drainage  areas  do not
support wetlands on-site.

9.1.2.3  WETLANDS CLASSIFICATION
A proposed system for categorization of wetlands within  the  central
Florida region was included in the Final Areawide Environmental  Impact
Statement for the Central Florida Phosphate Industry  [United States
Environmental Protection Agency (EPA), 1978],  This categorization was
intended to establish guidelines for the protection,  mining, and
restoration of wetlands within the phosphate region.  The  following
categories were defined:
     1.  Category I—Protected:
              "...wetlands within and contiguous to rivers and streams
              having an average annual flow exceeding 5  cubic  feet per
              second (cfs) as well as other specific  wetlands  determined
              to serve essential environmental functions,  including
              water quality (these are wetlands  that  provide an
              essential synergistic support to the  ecosystem and that
              would have an unacceptable adverse impact  if they  were
              altered, modified, or destroyed).  This generally  includes
              cypress swamps, swamp forests, wet prairies, and certain
              fresh water marshes."

     2.   Category II—Mine and Restore:
              "...wetlands that should be restored  as wetlands to
              perform useful wetland functions.  This also includes
              certain isolated noncategory wetlands that serve a primary
              function or several minor functions that may be  maintained
              through proper restoration."

     3.  Category III—Mine with No Restoration  to  Wetlands:
              "...wetlands that would not have to be  restored  as wet-
              lands.  These are isolated and normally intermittent in
                                 9-55

-------
              nature, have  less  significant  hydrological  functions  than
              Category LI,  and minimal  life-support  value."

A refinement of the EPA (1978) guidelines  for  wetlands  categorization
was first applied in the ESTECH  Mine EIS  (1979):

Category I - Protected
     A.  Mainstem Stream Wetlands:  These  are  wetlands  of  first  and
         second order rivers and streams  upstream  to  the point where
         mean annual flow  is 5 cfs.  Protection  shall extend  to  the
         lateral wetland boundary which shall  be the  25-year  flood
         elevation unless  such calculated  floodplain  is less  than one-
         half the total floodplain as determined by dominant  vegetation.
         In cases where the 25-year floodplain is  less  than one-half the
         total vegetated floodplain, a minimum of  one-half of the
         vegetated floodplain shall be protected from mining  and
         significant disturbance by mining operations.
     B.  Headwater Wetlands:  These are wetlands as defined by dominant
         vegetation that are found as the continuum of  first  and second
         order rivers and streams upstream of  the  point where mean
         annual  flow is 5 cfs.   A minimum of 25 percent by area of head-
         water wetlands shall be protected from mining  and significant
         disturbance by mining.   It  is the intent  to maintain stream
         wetland continuity by protection of headwater  areas.
     C.   Tr ib utary Wetlands:  Tributaries are  the  lateral streams,
         creeks  and  other contiguous water conveyances (whether
         permanent,  intermittant, or seasonal) that contribute flow  to
         first and second order  rivers and streams.  As the importance
         of  tributary wetlands  to regional hydrology,  water quality,  and
         fish and  wildlife habitat  may vary considerably due  to
         contiguity,  vegetative  structural diversity and hydro-period,
         exact determination as  Category I Tributary Wetlands will be
         made  on a site-by-site  basis.   In all cases,  however, a minimum
                                  9-56

-------
         of 25 percent by area of tributary wetlands shall be protected
         from mining and significant disturbance by mining.
     D.   Special Concern Wetlands:  Although not identified above,
         certain wetlands not part of stream floodplains may deserve
         special consideration for inclusion in Category I.  These
         include unique or unusual wetland vegetation communities  that
         would be difficult if not impossible to re-create, wetland
         communities rare to the  site or area, wetlands  supporting
         populations of endangered or rare animals or plants, wetlands
         of sufficient size to be significant wildlife habitat  (e.g.,  50
         acres with considerable  edge), or serve other essential
         environmental functions  including water quality.

Category II - Mine and Restore
     A.   Mainstern Stream Wetlands;  These are all  non-protected wetlands
         contiguous with the first and second order rivers  and  streams
         upstream to the point of 5 cfs mean annual flow.  This category
         reaches to the upland edge of the floodplain boundary  as
         determined by dominant vegetation from  the designated  limit  of
         Category I wetlands.
     B.   Headwater Wetlands;  These are all non-protected  wetlands that
         are found as the continuum of first and second  order rivers  and
         streams upstream of the  point of 5 cfs  mean  annual  flow.   This
         category reaches to the  upland edge of  headwater  wetlands  as
         determined by dominant vegetation from  the designated  limits  of
         Category I headwater wetlands.
     C.   Tributary Wetlands;  These are all non-protected  wetlands that
         are contiguous with the  lateral streams,  creeks and  other
         natural water conveyances (whether permanent,  intermittant,  or
         seasonal) that directly  contribute flow to the  first  and  second
         order  rivers and streams of  the region.
     D.   Isolated Wetlands;  These are all non-protected wetlands  in
         excess of 5 acres  in size that are not  contiguous to  mainstem
         streams, headwaters or tributaries but  do have  important
                                 9-57

-------
          functions  in  water  quantity and quality control and fish and
          wildlife  production.   Isolated  wetlands need not be replaced in
          their original  location  but must be  replaced in acreage equal
          to  total  acreage  destroyed  within each sub-drainage basin.
          Edge/area  relationship should be considered in isolated wetland
          replacement.

Category  III - Mine With No  Restoration  to Wetlands
          Category  III  wetlands are wetlands less than 5 acres in size as
          defined by dominant vegetation, are  isolated, have insignifi-
          cant hydrological function  and  do not  substantially contribute
          to maintenance  of fish and  wildlife  production in the region.

The above guidelines further defined wetland  category types, but did not
reflect differences  in functional  value.

As a  part of the Environmental Impact Statement (EIS) process and
assessment of potential  impacts resulting from  the proposed mine, the
functional role and supporting value of  on-site wetlands needed to be
evaluated.  This evaluation  would  identify the  environmental functions
of the various wetland areas and determine whether these areas provide
essential, useful, minor, or insignificant functions in support to the
ecosystem.

Wetlands  contained within each of  the 59 drainage units on the proposed
mine  site were delineated.   Each wetland unit was evaluated and noted
for wetland value using  the U.S. Array Corps of  Engineers (COE) wetland
evaluation procedure of  Reppert e_£ al_. (1979).

Reppert et^ al_. (1979)  stated that their  procedure was to be "based upon
available scientific knowledge about  wetlands and [that their system for
wetland evaluation] constitutes an interim tool  capable of filling an
immediate technology gap".  As a first approach,  the COE system is all
encompassing for wetlands from salt  marshes to  ephemeral freshwater
                                    9-58

-------
ponds.  Slight regional modifications to the evaluation  system were
necessary to provide for available scientific knowledge  about  central
Florida wetlands.  The resultant conclusions, based upon  this  evaluation
technique for the CF property, provide a best estimate  for  the wetland
systems functional tendencies.  Limitations with this approach are
inherent to a system based only upon three levels of valuation (i.e.,
high, moderate, low).

After final wetland/drainage unit values and rankings were  completed,
Che Areawide Phosphate EIS wetland categorizations values and  the ESTECH
wetland categorization guidelines were considered before  application of
a final designation.  As a result of the use of the COE  evaluation
procedure, few of the wetlands with mature old-age swamp  or bottomland
hardwood vegetation rated above average in value.  The majority of  these
areas (i.e., B6, S2, Dl, D3, D9, P2, C3) rated as average in overall
value.  The parameters developed in the COE method and used in this
study contain no specific reference to factors such as maturity of
vegetation, diversity of habitat or species, niche diversity (related  to
strata and species composition), or related  factors.  Such  values may  be
incorporated into an evaluation of habitat, but as such  are evaluated
subjectively and are averaged with other factors  so that  their relative
weighting becomes low.  Such values are generally not specific to
wetlands and perhaps should not be considered  in  an evaluation of
strictly wetland or  floodplain areas.  However, these are ecological
attributes of communities which usually require  longer  periods of time
for development.  As such, they may be rare  or even unique  within a
region.  Such factors  thus should be reviewed  in  a  determination of
categorization and have been considered in  the Category  I wetland
classifications.  Ability to restore,  under  existing  technology, also
was a critical factor  in developing wetland  categorizations.

A wetlands delineation map is  provided (Figure 9.1-3),  together with
Tables 9.1.7-6 and 9.1.2-7 listing wetland  acreages,  wetland categories,
sub-basin/drainage units, and  creek basins.

Category I  Wetlands
Horse Creek
Horse Creek is an intermittent stream flowing  through  the  western  end of
the property.  The stream has a reach of 3.ft miles above the  property
and drains approximately 17.9 square miles.  The  average annual
discharge at the exit of the CF property is estimated  to be approxi-
mately 10.7 cubic feet per second  (cfs).  Though  intermittent in nature,
the stream basin does collect and  retain pools  of water along its
primary channel.  The principal water retention area  is located  within
the central marsh system (H2).  This drainage  unit/wetland complex and
adjacent upstream (H3) and downstream units (HI)  provide relatively high
food chain production values, high habitat value, hydrologic  support,
and water purification function.  Therefore, because  of the composite
value of these systems and because of the large drainage basin and
average annual flow (exceeds 5 cfs) to which these interconnected
wetlands provide synergistic support, the Horse Creek  stream  channel and
contiguous wetlands located within HI, H2, and  H3 are  classified as
Category I A—Mainstem Stream Wetlands.

Mature hardwood swamps located in Units H4 and  H7 did  not  receive  high
value ratings due to minimal hydrologic connection and low net primary
productivity.  However, the two mixed hardwoods swamps were  considered
mature, relatively pristine associations and are  included  as  Category IA
—Mainstem Stream Wetlands.  Total acreage of  Category IA--Mainstem
Stream Wetlands within the Horse Creek drainage equals 70.7  acres.

Brushy Creek
Brushy Creek has its headwaters located within the western portion of •
the CF property.  This drainage headwater area composed of approximately
4.2 square miles, is contained almost entirely within the  CF  property
boundaries.  The estimated average annual discharge  from  this basin at
the property boundary is approximately 2.5 cfs.  The  drainage basin is
characterized by two distinct arms; one reach  containing  primarily
Mitchell Hammock (B4, B5, and B6), and another reach  comprising  a  major,
                              9-69

-------
Y-shaped  headwater  wetland  (B2).   These units converge and drain through
a poorly  defined  channel  and associated hardwood floodplain (Bl).  In
comparatively  evaluating  the Brushy Creek system,  it appears that its
highest  functional  values are related to its ability to store and hold
water  for  potential flood protection, the size of  its marsh-dominated
wetland  complex,  and its  associated net primary production values.  The
Mitchell  Hammock  unit (B4,  B5,  and B6) serves as a wetland headwater
area  to  the  Brushy  Creek  system.   However,  investigations conducted for
this  report  indicate that most  of its food-chain production values
(nutrient  transport)  are  not provided to the main  downstream complex
(Bl)  to a  significant  extent.   This occurs  since the poorly defined
channel/overflow  connector  through B4 tends to retain and internalize a
significant  portion of its  primary production values by retaining them
within the system.   This  effect is even further pronounced in the upper
reach of  the Mitchell  Hammock complex (B6)  since its hydrologic
connection is  felt  to  be  even less well defined and contributes to the
downstream units even  less  frequently.

The other major headwater wetland complex (B2) contributing to the
downstream Brushy Creek system  has similar  high storage values and is
characterized  by a  more functional connection and  more frequent and
pronounced hydrologic  transport values.   In evaluating the Brushy Creek
system and developing  a wetland categorization, it is felt that these
headwater wetland complexes  have,  as  their  most significant functional
values,  floodwater  storage,  size,  and the net primary production values
of the larger  marsh  complexes.

The largest  concentration of contiguous  marsh/swamp wetland is located
within Units BA and  B5.   Therefore,  these units are classified as
Category  ID—Special Concern Wetlands.   To  date, the restoration of
hardwood  swamps and  their biological  functions and values has not been
adequately demonstrated.  Therefore,  because of the relative value of  *
these systems  and their geographic extent,  it was  decided that a viable
mature hardwood swamp  component be preserved as a  seed source area.  The
                                 9-70

-------
wetlands determined to be most representative  of  the  mature vegetative
communities within the headwater wetland  complexes  and which would
provide the most viable contribution as a seed source are the central
hardwood swamp in B2 and the eastern mature  hardwoods in 86.  The
marshes immediately contiguous to the maple/tupelo  swamp in B6 and also
connected by channels to Drainage Unit B5 are  included,  together with
the B2 and B6 swamps, as Category I wetlands.   Unit B2 is classified as
a Category 1C—Tributary Wetland, while Unit B6 is  included together
with contiguous Units B5 and BA as Category  ID—Special  Concern
Wetlands.  Total Category I wetland acreage  to be protected from mining
within the Brushy Creek drainage is 446.2 acres.

Doe Branch
Doe Branch is an intermittent stream with its  headwaters located largely
within the CF property.  Doe Branch has a drainage  area  of approximately
7.8 square miles and contributes a calculated  flow  of 4.6 cfs at the
property boundary.  Doe Branch is the largest  and most complex drainage
system contained within the property boundaries.

In evaluating its functional values, the  system rated as moderate to
high for food chain production, wildlife  habitat, floodwater storage,
vegetation density and total area of wetlands.   Doe Branch is character-
ized by three discrete headwater reaches.

Above the principal Dl channel floodplain, one headwater wetland/
drainage area consists of Dll, D12, and D14, another  consists of D9,
DIG, and D13.  The third consists of D4,  D5, and D6.   The Dll, D12, and
D14 reach rated high for vegetation density  and inundation, and moderate
to low for all other values. The D9, D10,  and  D13 reach  rated high for
net primary production and moderate to low for all  other values.  The
D4, D5, and D6 branch rated high for net  primary  production, secondary
production, floodwater storage, inundation,  and total area of wetlands.
This reach received a higher composite rating  than  the other reaches in
the system.  However, it is similar to the Mitchell Hammock area in that
                                 9-71

-------
 much  of its net production values are internalized by a poor hydrologic
 connector to the downstream segments.  The weaker hydrologic connectors
 for D5 and D6 make this effect even more pronounced for these wetland
 units.

 In developing a categorization of the wetlands within this drainage
 basin and to ensure consistency with the areawide EIS guidelines, the
 overall high value should be assessed along with the restorability of
 functional components.   Although the wetlands within Units D4 and D5
 rated very high overall,  the majority of wetland type within the units
 is  marsh.   It is  believed that the functional values of these marsh-
 dominated drainage units  can be restored.  Therefore, the D4 and D5
 units are classified  as Category IIC—Tributary Wetlands.   However,
 within the Doe  Branch drainage, two mature hardwood swamps in Units D6
 and Dll  will  be preserved as a future seed source for on-site swamp
 restoration activities.   Because of the  relatively large drainage basin,
 its calculated  4.6 cfs  discharge,  and its high food-chain production
 values,  the mature hardwood  swamp  floodplain of Dl will be protected to
 serve  as  a  natural  buffer for Payne Creek from the upstream mining and
 restoration activities.

 Therefore,  consistent with  the areawide  EIS,  the wetland/floodplain unit
 within DL  (80.5 acres)  and  the mature hardwood areas within D6 and Dll
 (collectively 109.9 acres)  are classified as  Category 1C—Tributary
 Wetlands.

 Plunder  Branch
 Plunder  Branch  is  an  intermittent  stream with headwaters located on the
 eastern  portion of  the  property.   The  drainage basin of 4.5 square miles
 contributes  an  average  annual  flow of 2.7 cfs at the exit  from the
 property.

 In evaluating the  composite  functional values for Plunder  Branch, its
overall  comparative rating established the  system as  having a moderate
                                        9-72

-------
value.  The wetlands within the Plunder Branch system received  their
highest comparative values  for net  primary  production and  vegetation
density with other contributing functional  values being  ranked  moderate
to low.

Plunder Branch is divided  into two  distinct reaches  above  the stream
channel floodplain located  in PI.   One  reach (P2  and P3) contains
approximately one-third of  the upstream drainage  basin.  The wetland/
floodplain units located within this reach  are characterized by a young
maple hardwood swamp (P2) and an oak dominated hardwood  (P3) system.
The second reach (P4, P5, and P6) contains  approximately two-thirds of
the upstream drainage basin.  However,  P5 exhibits  a weak, possibly
ephemeral hydrologic link,  and Unit P6  is,  for all  practical purposes,
isolated.  The wetland  floodplain units within this  reach  are character-
ized by an oak/ash hardwood swamp (P4), an  oak dominated floodplain (P5)
and an open maidencane  marsh (P6).

In analyzing the functional values  for  the  Plunder  Branch  system, only
one unit (Pi) exhibits  characteristically higher  value.  The wetland
unit within PI was ranked high for  food chain production,  habitat value,
hydrologic support, flood retardation,  and  vegetation density.   Various
factors should be noted in  evaluating this  system,  including the unique-
ness of swamp type (species composition, diversity  and maturity), the
presence of an endangered  plant (needle palm) that  is  indicative of
permanent soil saturation conditions, and the presence of  pockets of
water, though intermittent, within  the  stream bed.

In developing the wetland categorizations consistent with  the areawide
EIS, the hardwood swamp within PI is classified as  a Category 1C—
Tributary Wetland.   The hardwood swamp within P2  is  considered  to be a
mature, diverse community and a viable  future seed  source.   Therefore,
P2 is also classified as a Category 1C—Tributary  Wetland.   Together,
the PI and P2 Category  I wetlands amount to 37.6  acres.
                               9-73

-------
Coon's Bay Branch
Coon's Bay Branch has  its  headwaters  located on the eastern border of
the CF property.  The  drainage  basin  and  average annual  discharge
calculated at the exit  from  the CF  property is  0.5  square miles and
0.3 cfs, respectively.  The  Coon's  Bay  drainage system contained on the
CF property  is  characterized by the upper extremities of one reach.  The
wetland units within this  system are  immature and mature maple hardwood
swamp systems ephemerally  to intermittently linked  to the downstream
systems.

In evaluating the composite  functional  values for  the Coon's Bay system,
it is characterized as  a comparatively  low value system.  The higher
functional values for  the  system were  flood retardation and vegetation
density (C3  only), with most  other  values ranking  low.  The maple/tupelo
swamp within Unit C3 is considered  a  mature hardwood wetland that could
be preserved for its flood retardation  value and possible future use as
a seed source.  Therefore, the  C3 (20.8 acres)  unit is classified as a
Category 1C—Tributary  Wetland.

Category II  Wetlands
Approximately 2,264.3  acres  of  wetlands within  each drainage basin
(i.e., if isolated greater than 5 acres in size or  connected or
contiguous to a main drainage channel)  are classified as Category II
wetlands.

Category III Wetlands
A Category III  wetland  designation  is  appropriate  for the remaining 550
acres of isolated, non-contiguous wetlands of less  than 5 acres in
size.

9.1.2.4  THREATENED OR  ENDANGERED SPECIES
Vegetation
Populations  of  endangered  native plant  species  have diminished in both
size and distribution  in Florida by man's disturbances or complete
                                9-74

-------
alterations to their specific habitat requirements.   Several
governmental agencies and private  institutions have  produced  endangered
plant species lists in order to protect  these Florida  plants,  or  other-
wise educate the populace of the existing  condition  and  importance  of
these taxa (USFWS, 1984; FCREPA, 1979; FDA,  1978;  SI,  1978; CITES,  1973;
.IUCN, 1972; USFS, 1970).

Plant species which have been listed by  these agencies and  special
concern groups and which have been observed  or may occur  on-site  are
listed in Table 9.1.2-8.  Officially, protected  plant  species which are
included as endangered or threatened by  the  USFWS  (1984)  were not
observed in the vicinity of  the CF Industries Hardee Phosphate
Complex II proposed mine site.  The only four plants listed as federally
protected [Harper's Beauty (Harperocallis  flava),  Florida Torreya
(Torreya taxifolia), Chapman's Rhododendron  (Rhododendron chapmanii),
and Key Tree-Cactus (Cereus  robinii)] are  either  restricted  to the
panhandle or the Florida Keys.

However, three important plant species  which have a  high likelihood of
occurrence or are present on-site, are  discussed  below,  including their
designated status.  Range and habitat  information, unless otherwise
cited, is from FCREPA (1979).

Spoon-Flower [Peltandra sagittifolia  (Michx.) Morong. ]
Spoon-flower is a rare perennial herb which  is known to occur from North
Carolina to Florida (FCREPA, 1979).   In Florida,  it  occurs throughout
the peninsula from Highlands, Hardee, and  Manatee counties north to
Jefferson County, with a disjunct  population in  the  panhandle.  Spoon-
flower inhabits wet soil areas such as  bogs, ditches,  valley  bottoms,
cypress swamps, bay forests, and  lake  and  stream margins.  There is a
high probability that spoon-flower occurs  within  the mature  bay and
mixed swamps on-site, since  the aroid  is frequent within its  habitat and
range.

Although Peltandra sp. is common within the tree swamps on-site,  the  two
species Peltandra virginica and Peltandra sagittifolia cannot  be  easily
distinguished without the benefit of  flowering and  fruiting  specimens,
which were not present during  the times of  investigation.

Florida Coontie (Zamia pumila  L.)
Zamia pumila L. is considered  the accepted  scientific name for Florida
coontie (Wunderlin,  1982).  In the past,  Florida coontie  was considered
as two  to  three separate  species and  given  specific degrees of protected
status by various scientific reports.  To avoid confusion, the
designated status of synonyms  of Florida  coontie  (i.e.,  Zamia floridana
A.DC., "L.  integrifolia Ait., and "L. umbrosa Small)  will  be collectively
grouped under  the specific  epithet of Zamia pumila  L.  Therefore,
Florida coontie has  been  listed as a  threatened  (FDA, 1978; FCREPA,
1979),  a vulnerable  (IUCN,  1972; CITES,  1973) and  an endangered (SI,
1978) species.

The Florida  coontie  is a  stout plant  which  has its  stem buried beneath
the soil.  The exposed deciduous leaves  are glossy  green and the plant
bears cones.   Coontie inhabits sandhills, pine flatwoods, shell mounds,
hammocks,  and  xeric  oak woods. Although  the coontie's range and
available  habitat occur  almost statewide, its numbers have decreaseed
gifeatly over  the years.   Coontie was  used for flour by the  Indians in
the past,  and  currently  this  cycad  is being exploited in  the nursery
trade as an  ornamental.   In the  CF  Industries DRI  (1976), the Florida
coontie  was  listed  as present  within  the flatwoods on-site.  However,
specific map locations were not  provided, and Florida coontie was not
observed during  the  1982  field investigations.  It  is doubtful that  the
cycad has  disappeared since 1976.   However, since   the occurrence of
Florida coontie  was  not  verified  during field reconnaissance, it  is
rated with a "high  probability of  occurrence" on the site.

Needle  Palm  [Rhapidophyllum hystrix (Pursh) Wendl.  6^ Prude]
Needle  palm  has  dark green, evergreen leaves and a stout  stem which
bears  sharp-pointed  spines at  the  bases of the petioles.  Needle  palm
                                9-77

-------
grows  in  forested  habitats  which are wet throughout the year, such as
hammocks  hammocks  along  spring-fed creeks, swamp and floodplain seepage
areas, hackwater swamps,  and  wooded riverbank ravines.

Needle palm  occurs intermittently from Highlands and Hardee counties
northward  to  Alachua  County and then westward to Walton County in
Florida.   During the  drainage walkover surveys, needle palm was dis-
covered within a mixed hardwood swamp just south of northern site
boundaries,  where  Plunder Branch exits the property (Unit PI).  Needle
palm has been designated  as both a threatened (SI, 1978; FDA, 1978;
FCREPA, 1979) and  a vulnerable species (IUCN, 1972).  Interspersed
throughout the tree swamp were 45 healthy specimens of the palm.
Herbarium  records  (USF Herbarium, 1982), pertinent literature (FCREPA,
1979;  Shuey and Wunderlin,  1977), and personal communications with
needle palm experts (Shuey,  1982; Wunderlin,  1982) agree that needle
palm has never been discovered  within a mixed hardwood  swamp type such
as the habitat situated on  the  property.  Only one other known location
of needle  palm exists in  Hardee County, some  8 miles due south along the
Peace River drainage.  The  two Hardee County  populations, together with
a population center in Highlands  County, constitute the southernmost
limit  of the  palm  in  the  United States.

Wildlife
It has been determined that  a number of wildlife species populations
have declined dramatically  in recent years.   As a result, the U.S. Fish
and Wildlife Service  and"  the  Florida Game and Fresh Water Fish
Commission have afforded  legal  protection to  species considered
endangered,  threatened, rare  or of special concern.

The CF Industries  Hardee  Phosphate Complex II site is  known to provide
habitat for a number  of these protected species and may provide suitable
habitat for others that have  not  yet been observed on  the site.   The
species that are known (or  expected  to occur) in the vicinity of the
CF site are discussed below and are  included  in Table  9.1.2-9.

Reptiles
American Alligator (Alligator mississippiensis)—The American  alligator,
currently federally listed as threatened, inhabits swamps,  streams,
sloughs, lakes, and marshes.  At one time, heavy poaching  for  hides  and
destruction of wetland habitat threatened the continuation  of  this
species.  Since its classification as a  protected  species,  the alligator
has made a remarkable recovery.  This large reptile is  now  fairly  common
throughout Florida.  It has reached  sufficient numbers  to  be  considered
a pest in some areas of the state.

At least two alligators were  frequently  observed  in  the intermittent
drainage which flows from Mitchell Hammock into Brushy  Creek (CF DRI,
1976).  During the 1982 field  investigations, alligators or signs  of
alligators were observed throughout  the  CF Industries  Hardee  Phosphate
Complex II site.  Almost every stock pond or borrow  pit which contained
permanent water supported at  least one alligator.  A  perched,  isolated
freshwater marsh near the northern boundary of the site, within the
Shirttail Branch drainage, supported two alligators.   Within  the Doe
Branch drainage, eight alligator young were discovered  within a marsh
edge to a maple swamp.  A large (approximately 8  feet  long) alligator
has been observed within the  central marsh located in  Mitchell Hammock.
Within the Horse Creek channel, two  large, deep circular pools, cleared
of the surrounding marsh vegetation, appeared to  represent  alligator
holes.  However, alligators were not observed in Horse  Creek  during the
field studies.

Alligators are expected to occupy areas  of suitable  habitat provided by
Brushy Creek, Lettis Creek, and Plunder  Branch.   Some  of the  larger
marsh systems on the CF site  may also be of value  to  the American
alligator.

Gopher Tortoise (Gopherus polyphemus)—The gopher  tortoise is a
terrestrial tortoise of well-drained communities  where it excavates
underground tunnels.  Gopher  tortoise burrows provide shelter for other
                                 9-81

-------
animals including:   gopher  frogs,  indigo  snakes,  diamondback rattle-
snakes, burrowing  owls,  small  mammals  and numerous insects.  Decline of
the tortoise,  listed as  a species  of special  concern,  has been attri-
buted  to their over-harvesting  for food  and  to  loss of habitat.  The
gopher tortoise has  been observed  on the  CF  site  and is considered
common, based  on numerous burrows  present in  pine flatwoods and other
upland communities.

Eastern Indigo Snake (Drymarchon corais  couperi)—The  eastern indigo
snake  is designated  threatened  by  both  federal  and state agencies.  This
large, docile  reptile has been  the target of  many snake collectors, and
its importance in  the pet trade has been  a major  factor in its decline.
The indigo inhabits  both upland and  lowland  communities including
hydric, mesic and  xeric  hammocks,  swamps, marshes, and flatwoods.
During the summer  months, indigo snakes  of upland areas may seek shelter
in gopher tortoise burrows.

At least three indigo snakes have  been  observed in the large southern
tract of the CF property (CF DRI,  1976).   Considering  these sightings
and the large  area of suitable  habitat  on the CF  site, the indigo
snake's occurrence is judged as common.

Birds
Woodstork (Mycteria  americana)—The Woodstork is  a colonial wading bird
considered endangered by the Florida Game and Freshwater Fish Commission
and the U.S. Fish  and Wildlife  Service.   The  Woodstork is North
America's only native stork and inhabits  freshwater and brackish
wetlands.  Nesting occurs in mangrove  and cypress swamps.  Freshwater
marshes, flooded pastures and ditches  are primary feeding areas.  The
decline of Woodstork populations is attributed  to man's manipulation of
wetland water  levels which  alter or eliminate vital feeding areas.
                          4
Woodstorks have been observed  in the vicinity of  the CF site, and they
are expected to feed in  suitable wetlands within  the site boundaries.
                                 9-82

-------
Southern Bald Eagle (Haliaeetus JL_._ leucocephalus)—The  Southern Bald
Eagle inhabits rivers, lakes, and estuaries  of  the southeastern United
States.   Nesting occurs in pine and cypress  trees  in  proximity to water,
with fish being the primary  food.  No  lakes  or  rivers occur  on the CF
site, and the small borrow pits are not suitable for  the  eagle's needs.
Bald eagles are not expected on the CF  site  except as transients.  The
closest  suitable eagle habitat to the  site is  found  in  the Peace River
system to the east and the Manatee River  system to the  west.

Red-cockaded Woodpecker (Picoides borealis)—Florida  populations of the
Red-cockaded Woodpecker are  presently  considered endangered  by the U.S.
Fish and Wildlife Service and threatened  by  the  Florida Game and Fresh-
water Fish Commission.  This woodpecker is found in  southern pine
flatwoods.  Habitat requirements for nesting and daily  roosting include
live, mature, or overmature  pine trees  (longleaf pine is  most commonly
used).  Because of past logging on the  CF site,  few mature stands of
pine exist.  Remaining stands of mature longleaf pine were surveyed and
judged suitable for red-cockaded use.   Individual  trees were examined
and revealed neither nest nor roost cavities,  and  no  Red-cockaded
Woodpeckers were found.  This protected woodpecker is believed to be
absent from the CF site.

Southeastern American Kestrel (Falco sparverius  paulus)—The South-
eastern American Kestrel, a  subspecies of the  American  Kestrel is a
small falcon considered threatened by  the State  of Florida.   This bird
^   •>
inhabits open areas including pastures, rangeland, and  other ruderal
areas on the CF site.  The kestrel feeds  on  insects  and small mammals
and nests in cavities in trees or artificial structures.   Population
decline of this species is attributed  to  loss  of nesting  sites.

Florida Sandhill Crane (Grus canadensis pratensis)—The Sandhill Crane
is listed as threatened by the State of Florida and  is  non-migratory,
unlike the northern subspecies.  Cranes inhabit  shallow marshes, lake
edges, and flooded open pastures.  Nests  are constructed  in  shallow
                                  9-83

-------
water that is approximately one  foot  in  depth.   A naturally low
reproductive rate combined with  loss  of  wetland  habitat  has caused the
decline of this species.  Suitable  crane habitat  exists  on  the  CF
property, and Sandhill Cranes  have  been  observed  on-site.

Wading Birds—Four wading bird species are  designated  Species of  Special
Concern by the State of  Florida  and have been observed on  the CF  site.
These are the Little Blue Heron, Louisiana  Heron,  Snowy  Egret and
Roseate Spoonbill.  The  herons and  the egret utilize  freshwater marshes,
shrub swamps, flooded pastures,  and drainage ditches.   Roseate  Spoon-
bills are primarily coastal waders; however, they do  feed  in freshwater
marshes infrequently.  Cause for concern for these  wading birds is due
to  loss of wetland habitat.  The CF site is observed  to  be  an  important
feeding and staging area for waders, but  positive  nest records  have not
been substantiated.

Burrowing Owl (Athene cunicularia floridana)—The  major  population of
Burrowing Owls is located in south-central  Florida  where it inhabits dry
open areas of prairie, sandhill, and  pasture communities.   Extensive
land development is believed to  play a part in the  decline  of this owl's
population.  Displaced Burrowing Owls have  moved  onto  golf  courses,
grasslands at airports and industrial sites and  landfill areas.
Suitable Burrowing Owl habitat occurs on the CF  site  in  pastures  and
open rangeland, but no owls have been observed.

Mammals
Florida Panther (Felis concolor  coryi)—The Florida panther is  a  large,
light brown-colored cat which  is designated "endangered" by federal and
state agencies.  Requirements  of this secretive  predator's  habitat
include vast areas of relatively undisturbed wilderness  areas.  Such
areas are provided by the Fakahatchee Strand, Big  Cypress Preserve and
Everglades National Park in southern Florida.  No  recent substantiated
sightings have been made in the  vicinity of the  CF  site.  Due  to  the
                               9-84

-------
altered condition and openness of the site,  suitable habitat  is  not
provided, and no Florida panthers are expected  to occur.

Florida Black Bear (Ursus americanus floridanus)—The  Florida black  bear
is considered threatened by the Florida Game and Fresh  Water  Fish
Commission.  This large mammal inhabits swamplands with  dense under-
growth, and feeds on fruits, berries, insects,  honey,  and  occasionally
wild hogs and cattle.  A number of recent records of bear  populations
occur throughout Florida, including portions of Hardee  County.   Bear
populations appear to be stable in national  forests  in  northern  Florida,
but elsewhere in the state populations are vulnerable.   Habitat  loss and
persecution by man have attributed to the decline of bear  populations.
No recent bear sightings have occurred on the CF property, but
considering their wandering nature, bears may be expected  to  occur in
suitable habitat onsite.

9.1.2.5  RECREATIONALLY AND COMMERCIALLY IMPORTANT WILDLIFE
The varied habitat found on the CF site supports several important game
and fur-bearing animals.  These include upland  game  birds, waterfowl,
large mammals, and small game and fur-bearing mammals.

Upland Game Birds
Bobwhite Quail, Mourning Doves, and Wild Turkey are  important game bird
species on the CF site.  Quail and Mourning  Doves are  reported to be
abundant, while turkeys are considered common.  Quail  and  doves  utilize
similar habitat provided by open areas—rangeland, pastures,  flatwoods,
and ruderal areas.   In these open areas they feed on  seeds and
vegetation provided  by dense growth of herbs and shrubs.  Several
turkeys were observed on the site in both ruderal and  hardwood hammock
communities.
                                       9-85

-------
Waterfowl
The numerous wetlands on  the CF  site  are  a valuable  resource  for water-
fowl.  The Mottled Duck is believed to  be  the  only breeding duck in the
region.  Numerous other duck species  utilize marshland  and  wintering
areas.  The most common migrants and  winter residents  include  Blue-
winged Teal, Green-winged Teal,  American  Widgeon,  Ring-necked  Duck and
Lesser Scaup.  The Wood Duck is  a year-round resident,  but  is  believed
to breed further north in Florida.

Large Mammals
Recent wildlife surveys indicated healthy  populations  of  large mammals
on the CF site.  White-tailed deer were observed often  in  flatwoods and
hammock edges and were judged abundant.  Wild  hogs were common to
abundant on-site.  Several hogs  and their  characteristic "rooting" signs
were observed in hardwood hammocks, rangeland,  swamps,  and marsh edges.

Small Game and Fur-Bearing Mammals
The CF site supports a number of small  game and  fur-bearing mammals.
Some of the more common species  include opossum, raccoon, marsh rabbit,
eastern cottontail, and gray squirrel.  Other  more secretive  species
include red fox, gray fox, and bobcat.  The round-tailed muskrat,
although not sighted, is considered abundant in  the  numerous marshes.
Many muskrat feeding platforms, dens  and scat  were sighted during field
surveys.  Other species not sighted,  but  possibly occurring on-site, are
the long-tailed weasel and river otter.

                     10.I  THE AFFECTED ENVIRONMENT
This section, which discusses regional and local socioeconotnic environ-
ments, represents a baseline description of existing and  future condi-
tions without implementation of the proposed project.  Most information
for this section was obtained from recent national,  state, and local
sources.

In general,  the socioeconomic region  is defined as Hardee, DeSoto,
Highlands, Hillsborough, Manatee, and Polk Counties.  The local area
consists of Hardee County, within which the proposed project  is located.
Where appropriate, regional and local boundaries are expanded or
contracted to reflect data availability or impact considerations.   In
addition, site descriptions are provided.  Socioeconomic elements
described in the baseline description include population, income and
employment; land use; transportation; commmunity services and
facilities; public finance; cultural  resources; and visual resources.

10.1.1  POPULATION. INCOME AND EMPLOYMENT
10.1.1.1  POPULATION
In 1983, Hardee County had a population of 19,782 residents or approxi-
mately 1.5 percent of the regional population of 1,293,877 (see
Table 10.1.1-1) [University of Florida, Bureau of Economic and Business
Research (BEBR), 1984],  Hardee County ranks 49th (of 67 counties)  in
population size in Florida and is slightly larger than DeSoto County,
located immediately south of Hardee County (BEBR, 1984).

The county is characterized by rural development, with 65 percent of the
1983 population residing in unincorporated areas.  This figure is simi-
lar to 1970 population distributions which showed 63.2 percent residing
in unincorporated areas.  Three incorporated municipalities are located
in Hardee County.  Wauchula, the county seat, had a 1983 population of
2,971 inhabitants (BEBR, 1984).  The remaining municipalities, Bowling
Green and Zolfo Springs, had 2,305 and 1,592 persons, respectively,
residing within municipal boundaries (BEBR, 1984).

The current (1983) population density in Hardee County is 31.0 persons
per square mile, which ranks 46th in comparison to other Florida
counties.  The regional and statewide population densities are 218.4 and
196.0 persons, respectively.

Between 1970 and 1983 population growth in Hardee County was  less  than
that recorded for the region and Florida (see Table 10.1.1-1).  During
this period, Hardee County's population increased by 33.0 percent,  for
an average annual growth rate of 2.5 percent.  Municipal population
growth in the county averaged 31.8 percent, varying from a 70.0 percent
increase in Bowling Green to a 1.2 percent decrease in Wauchula.

Population change from 1970 to 1980 was a result of both natural
increase and net migration.  The U.S. Bureau of the Census attributed
37.2 percent of the county's total population increase of 4,490 to
natural increase—the number of births being greater than the number of
deaths.  Net migration, the result of in-migration and out-migration,
was responsible for the remainder of the increase—2,818 persons or
62.8 percent.

10.1.1.2  INCOME
Per capita income in Hardee County, other counties in the region,  and
the state is identified in Table 10.1.1-2.  Per capita incomes in  1982
for Florida and Hardee County were $10,907 and $7,792, respectively.
Local  personal incomes averaged 28.5 percent less than statewide
personal incomes.  Hardee County ranks 21st of 67 Florida counties  in
personal income.  Florida per capita income increased by $5,337 between
1975 and 1982.  During the same period, Hardee County per capita income
increased $3,560 (BEBR, 1984).

-------
Per capita income in Hardee County, when compared to statewide statis-
tics, is characteristic of other counties in the region.  Per capita
income in all six counties is less than the state average with the
exception of Manatee County in 1982.  The 1982 figures range from $7,779
in DeSoto County to $11,011 in Manatee County.  Also similar to Hardee
County trends is the tendency of three of the six regional counties to
increase per capita income slower than statewide averages.  Only Manatee
and Highlands Counties increased the percentage of statewide income
averages.

The agricultural sector is the largest source of earned  income in Hardee
County, followed by the government sector and retail trades.  Total
Labor and proprietors' income in the farm sector for Hardee County
during 1982 was $31,399,000.  Non-farm income totalled $50,181,000.
Government-related personal income totalled $13,717,000  (BEBR, 1984).
The breakdown of 1982 private non-farm income indicates  that retail
trades contributed $9,015,000.  Service industries provided $7,429,000
and manufacturing contributed $5,278,000.

10.1.1.3  EMPLOYMENT
The total 1983 labor force in the six-county region was  624,289 (Florida
Department of Labor and Employment Security, 1985).  As  expected,
Hillsborough County had the Largest labor force (362,870 persons) and
DeSoto the smallest (7,665 persons).  The total number of regional labor
force unemployed (1983 annual average) was 62,570 or 10.0 percent.
County level unemployment rates ranged from a high of 15.6 percent for
Polk County, to 7.6 percent for Manatee County.  Hardee  County's unem-
ployment rate for 1983 was 12.3 percent (Florida Department of Labor and
Employment Security, 1985).

Estimated 1982 monthly non-farm employment  in Hardee County averaged
3,330 positions.  Table 10.1.1-3 identifies the industries within which
these positions were classified and compares these figures to
region-wide totals.  In terms of number of employed, services, wholesale
                                     10-5

and retail trades, and government are the largest non-farm employers in
Hardee County.  Over 71.6 percent of Hardee County's non-farm employed
are located in these industrial classifications.  For the region, these
three classifications account  for only 63.5 percent of total non-farm
employment.  The major classifications on a region-wide basis are
wholesale and retail trade, and services.

Estimated 1980 average monthly agricultural employment of proprietors
and wage and salary workers are developed by the U.S. Department of
Commerce.  The agency estimates 1,173 farm proprietors were  located  in
Hardee County in 1980.  In addition, approximately 911 average monthly
wage and salary positions result from agricultural activity  in the
county.  These wage and salary related positions account  for
16.2 percent of all wage and salary employees in Hardee County.

10.1.1.4  PROJECTIONS
Using 1980 census information, BEBR annually projects future population
growth for each county in the state.  These projections, defined by  BEBR
in Florida Statistical Abstract, are based on three assumptions
regarding annual net migration in Florida:
     1.  High projections are similar to the large migration levels  of
         the first half of the 1970s when more people were migrating to
         Florida than ever before.
     2.  Medium assumptions imply annual net migration levels similar to
         the average growth in the 1970s.
     3.  Low migration levels are similar to small migration levels
         experienced during 1975 to 1977.

County projections are based on the ratio of each county's share of  the
total state increase in population from 1970 to 1980.

Table 10.1.1-4 identifies BEBR projections for the state, region, and
Hardee County.  Utilizing the medium growth projections identified by
BEBR, it is estimated that Hardee County will grow in population from
                                      10-7
