 Subject:      Naval Air Station Cecil Field, Jacksonville, Florida
              Record of Decision for Operable Unit 3 (Site 7)

 Dear Mr. Glass:

       The U.S. Environmental Protection Agency (EPA) has reviewed the final Record of
 Decision (ROD) for Operable Unit 3 (Site 7) and concurs with the selected remedies for the
 remedial actions. These remedies are supported by the previously completed Remedial
 Investigation, Feasibility Study, Technical Memorandum for Surface Soil Remediation, and the
 Baseline Risk Assessment The selected remedies includes institutional controls on future
 groundwater usage, soil excavation and long term groundwater monitoring.

       EPA Region 4 issued, on April 21,1998, a memorandum titled "Assuring Land Use
 Controls at Federal Facilities." The content of that memorandum deals with land use controls for
 properties which are not imminently being transferred to a non-federal entity. However, until
 that time in which Site 7 is transferred by deed to a non-federal entity, EPA believes that our
 April 21,1998, policy on land use controls should apply.  Therefore, we are concurring with the
 condition that a Land Use Control Assurance Plan (LUCAP) be developed.

      Thus, EPA's concurrence with the Record of Decision (ROD) for OU 3 (Site 7) is
 conditioned on the express understanding that the Navy is committed to entering a Memorandum
 of Agreement (MOA) with EPA Region 4 and the Florida Department of Environmental
protection (FDEP) that complies with the April 1998 Memorandum mentioned above withia 90-
days of this letter. This MOA will serve as the LUCAP for NAS Cecil Field.  Once the LUCAP
is in place, the NAS Cecil Field BRAC Cleanup Team (BCT) will be expected to develop

 specific provisions for land use controls as part of the resulting Land Use Control
 Implementation Plan for Site 7, that will prohibit unrestricted property reuse until cleanup goals
 are met.

        EPA appreciates the coordination efforts of the Navy and the level of effort that was out
 forth m the documents leading to this decision. EPA looks forward to continuing the excellent
 working relationship with NAS Cecil Field and Southern Division Naval Facilities Engineering
 Command as we move toward a final cleanup of the NPL site.  Should you have any questions*

                  1.0   DECLARATION FOR THE RECORD OF DECISION


1.1  SITE NAME AND LOCATION.  Site 7, Former Firefighting Training Area, Operable
Unit  (OU)  3, is  located near  the  northwest  end  of  the  old 310  flightline
approximately 800 feet east  of Lake Fretwell and 1,200  feet  northwest of the
east-and-west flightline on the main base of Naval Air Station (NAS) Cecil Field,
Jacksonville, Florida.   Approximately 2,000 feet east of Site 7 are the aircraft
hangars, Buildings 13 and 14.


1.2  STATEMENT  OF BASIS AND PURPOSE.    This  decision document presents the
selected remedial action (RA) for Site 7, located at NAS Cecil Field, Jackson-
ville, Florida,  which was chosen in accordance with the Comprehensive Environmen-
tal  Response,  Compensation,   and  Liability  Act (CERCLA),  as  amended  by the
Superfund Amendments and Reauthorization Act of 1986, and the National Oil and
Hazardous  Substances   Pollution  Contingency Plan  (NCP)  (40  Code  of Federal
Regulations  300)  (U.S.  Environmental  Protection Agency  [USEPA],  1990).   This
decision document was  prepared in accordance with  the USEPA decision document
guidance (USEPA, 1992).  This decision is based on the Administrative Record for
Site 7, OU 3.

The USEPA and the State of Florida concur with the selected remedy.


1.3  ASSESSMENT OF THE  SITE.  Releases of hazardous substances from this  site,
if not addressed by implementing the response actions selected in this  Record  of
Decision (ROD), may present  an  imminent  and substantial endangerment  to public
health,  welfare,  or the environment.    Human  health  risks are posed if the
groundwater from the surficial aquifer was used as a potable water source.   Human
health  and possibly wildlife may be at risk  if exposed to Site 7 surface  soil.


1.4  DESCRIPTION  OF  THE SELECTED REMEDY.   This ROD is the  final action for
Site 7, OU 3.   Final RODs  have been approved for OUs 1, 2,  4, 6, 7,  and  8 and
Site 14, which is part  of OU  5.  Remedial investigations (RIs)  and baseline risk
assessments  (BRAs) have been completed for OU 3 (Site 8)  and OU  5 (Site 15) and
are  underway for  OU 9.

The  selected  remedy addresses risk reduction in soil and groundwater at Site  7.
Remedial  alternatives  selected for  Site 7 include surface  soil  excavation and
groundwater  monitoring.

The major components of the selected remedy are listed below.  The selected soil
alternative  includes

          excavating approximately 3,901  cubic  yards  (yd3) of  surface  soil (for
          a residential land-use scenario to  a  depth  approximately  1  foot  below
          land surface  [bis]) located in  an open field at the end of the old  310
          flightline;

      •    disposing of  the excavated surface soil to an eligible landfill, either
          a  Resource Conservation  and Recovery  Act (RCRA)  Subtitle D  (solid
          waste) landfill or  an RCRA Subtitle C (hazardous waste) landfill;

 Cec-S7.ROD
 PMW.O2.99                                1 -1

-------
         backfilling the excavated area with clean soil; and

         seeding  and fertilizing  the  excavated  area  to promote  vegetative
         growth.

The selected groundwater alternative includes

         restricting use of the surficial aquifer groundwater at Site 7,

         monitoring the groundwater for a period for 30 years or  less if benzene
         concentrations meet guidance criteria (State of Florida drinking water
         standards), and

     •   reviewing the status every 5 years until cleanup goals are achieved.


1.5  STATUTORY DETERMINATIONS.  The selected remedy is protective of human health
and the environment, and is cost effective.  The nature of the  selected remedy
for Site 7 is such that the single benzene detection  in groundwater may remain
above regulatory  standards during the RA.  As a result, applicable or relevant
and appropriate requirements  (ARARs)  will  not be met as a near-term goal, but
will be met  as a  long-term goal.   The remedy utilizes permanent solutions and
satisfies the statutory preference for remedies that reduce  toxicity, mobility,
or volume as a principal element.  Because this remedy would result in hazardous
substances remaining onsite above heath-based levels,  a review will be conducted
within 5 years of the commencement  of RAs to ensure that the remedy continues  to
provide adequate  protection of human health  and  the  environment.


1.6  SIGNATURE AND SUPPORT AGENCY ACCEPTANCE OF  THE  REMEDY.

                             2.0  DECISION SUMMARY


2.1  SITE SAME. LOCATION. AND DESCRIPTION.  NAS  Cecil Field is located 14 miles
southwest of  Jacksonville,  Florida.   The majority of Cecil  Field is located
within Duval County;  the southernmost part of the facility is located in northern
Clay County (Figure  2-1).

NAS Cecil Field was  established in 1941 and provides facilities, services, and
material support for the operation and maintenance of naval weapons, aircraft,
and other units  of  the operation  forces  as designated by the  Chief of Naval
Operations.    Some  of the tasks required  to accomplish  this  mission over past
years included operation of fuel storage  facilities, performance  of aircraft
maintenance, maintenance and operation of engine repair facilities and test cells
for turbo-jet engines, and support of special weapons systems.

NAS Cecil Field is scheduled for closure in 1999.   Much of the facility will be
transferred to the Jacksonville Port Authority.  The facility will have multiple
uses, but will be used primarily for  aviation-related  activities.  The area,
which includes Site  7, is scheduled for aviation-related activities.

Land surrounding  NAS Cecil  Field is used primarily for forestry,  with some
agriculture and ranching use.   Small communities and individual dwellings are in
the vicinity of NAS Cecil Field.  The closest  community, located on Nathan Hale
Road,  abuts  the  western  edge of  the  facility.    The nearest  incorporated
municipality, Baldwin, is approximately 6 miles northwest of the main facility
entrance.

To the east of NAS Cecil Field, the rural surroundings  grade into a suburban
fringe bordering the major east and west roadways.   Low commercial  use, such as
convenience stores,  and low density residential  areas characterize  the land use
(ABB Environmental Services, Inc. [ABB-ES], 1992).  A development  called Villages
of Argyle,  when complete, is planned to consist  of seven separate villages that
will ultimately abut NAS Cecil Field to the south  and southeast.  A golf course
and residential area also border NAS Cecil Field to the east  (Southern Division,
Naval Facilities Engineering Command [SOUTHNAVFACENGCOM], 1989).

Site 7  is located near the west end of the east-and-west flightline (SOUTHNAVFAC-
ENGCOM,  1989).  Resultantly,  there  is  no housing  in the immediate  vicinity of
Site  7.    The nearest housing,  the  bachelor  officer  quarters,   is  located
approximately  2,500  feet north to northeast of the site.

Site 7, Former Firefighting Training Area, is  located near  the northwest end of
the old  310 flightline on  the main base  (Figure  2-2) .   The site is located
approximately  800  feet  east of Lake Fretwell and  1,200  feet northwest of the
east-and-west  flightline.   Approximately 2,000 feet east  of  the site are the
active aircraft hangars, Buildings 13 and  14.

Site 7  is relatively  flat, gently sloping to the west and southwest (Figure 2-3).
The dominant  features at Site  7 are  the old flightline and adjoining apron and
a  storage   unit,  Building  865.    The  areas  immediately  surrounding  the old
flightline are open,  grassy fields.   There  is no obvious surface  drainage at the
site.  Site  7  is accessible by the current east-and-west flightline apron and by

an unpaved service road.  Immediately west of the end of the old flightline is
the Lake Fretwell access  road,  which is  separated from the site by a security
fence.

Currently, Site  7 is  used  as an  ordnance  storage and general  storage area..
Storage structures are located at the end of the  old 310 flightline.  Explosive
ordnance is stored in  Building 865, and unarmed ordnance is stored in portable
storage units.   Building  865 was erected sometime after firefighting training
ceased in 1975 and before 1980,  as evidenced by aerial photographs.


2.2  SITE  HISTORY  AND ENFORCEMEHT  ACTIVITIES.    Site  7  consisted  of  two
firefighting training  areas on the old asphalt  flightline (both of which arc
located within the large circle shown on Figure 2-3) and an unlined pit northeast
of and adjacent  to the old  flightline.   From the 1950s to 1965, firefighting
training activities were  conducted on the old flightline.  From approximately
1965 until firefighting training ceased in 1975, firefighting training activities
were  also conducted  in  the unlined pit.   Firefighting  training activities
included placing aircraft frames on the old flightline  and in the pit and  dousing
the  frames with  flammable   liquids.    The  aircraft  frames were  ignited,  and
firefighting personnel practiced fire containment and extinguishing techniques
on  the  burning  frames.  Flammable  liquids used in  the  training activities
included waste paints  and paint  thinners, spent  chlorinated and nonchlorinated
solvents,  and  petroleum,  oil, and lubricant wastes.   Extinguishing  materials
consisted of water and nontoxic  proteinaceous materials such as  fish, feather,
horn, or hoof meal.  Extinguishing materials and unburned wastes were left on the
site, where they evaporated, infiltrated  through the  cracks  in  the  asphalt and
into the soil, or migrated  from the  site  via surface  runoff.

NAS Cecil Field was placed on the National Priority List (NPL) by the  USEPA and
the  Office of Management and  Budget in December 1989.    a Federal Facility
Agreement  (FFA)  for NAS  Cecil  Field was signed by  the Florida Department  of
Environmental Protection (FDEP)  (formerly the Florida Department of Environmental
Regulation) , the USEPA, and the Navy  in 1990. Following the listing of NAS Cecil
Field on  the  NPL and  the signing  of the site management  plan  (SMP), remedial
response  activities at the  facility  were  conducted under  CERCLA authority.

Investigations at Site 7 began in  1985.  The previous  investigations are listed
in  chronological order:                "

 2.3  HIGHLIGHTS OF COMMOHITY PARTICIPATION.  The results of the RI and the  BRA,
 the remedial alternatives of the FS, and the preferred alternative given in the
 Proposed Plan have been presented to the NAS  Cecil  Field  Restoration Advisory
 Board (composed of community members as well as representatives from the Navy and
 State and Federal regulatory agencies).

 The RI and BRA results and the remedial alternatives  of  the FS were presented at
 RAB meetings held on August 19, 1997, and September 16,  1997, respectively.   The
 preferred alternative was presented at the November 18, 1997,  RAB meeting. A 30-
 day public comment period  was held from October 28  through November 28, 1997.
 No  comments were received during the comment period.

 Public notices of the availability of the Proposed Plan  were placed in the Metro
 section  of the Florida Times Union on November 1, 1997.   These local editions
 target  the communities  closest to NAS Cecil  Field.   Documents pertaining  Co
 Site 7 are available to the public at the Information Repository, located at the
 Charles  D. Webb Wesonnett Branch of the Jacksonville Library, 6887  103rd Street,
 Jacksonville, Florida.


 2.A....SCOPE..AND ROLE OF OP.  The environmental concerns at NAS  Cecil  Field are
 complex.   As a result,  work at the various sites  has been  organized  into eight
 Q\JS  along with  more  than 100  other areas undergoing  evaluation in the  Base
 Realignment  and Closure and underground  storage tank programs.

 Final RODs have been approved for OUs 1,  2, 4,  6,  7, and 8 and Site 14, which is
 part of OU 5.  RIs and BRAs have been completed for OU 3 (Site 8) and OU 5 (Site
 15)  and  are  underway for OU 9.

 Investigations  at OU  3,  Site  7,  indicated  the presence  of surface soil  and
 groundwater  contamination.  The  purpose of  this RA  is to remediate the  soil
 contamination and monitor and remediate the groundwater  contamination that  pose
 human health risks.   Inhalation or ingestion of surface soil and  ingestion  of
 groundwater  extracted  from the surficial aquifer pose human health risks  that
 exceed the State, of Florida  threshold of 1x10"*.

 The  remedial  action objectives  (RAOs) listed below were  established for Site  7.

          Prevent exposure to contaminants that pose an unacceptable human health
          risk and are  present  at  concentrations exceeding  the  Florida  soil
          cleanup goal  for  industrial  sites.

          Prevent exposure to groundwacer that contains benzene at concentrations
          greater than  the  Florida  groundwater  cleanup goal.

The RA documented in chis  ROD  will  achieve these  RAOs.

2.5  SUMMARY OF SITE CHARACTERISTICS.

Geology.  Geologic materials  recovered during drilling  operations at  Site 7
indicate that the site  is  underlain by approximately 85  feet fine- to medium-
grained sand with some  silty sand, clayey sand, and clay stringers.   Beneath
these sandy materials is a sandy clay with dolomite pebbles unit.  This clayey
unit is approximately 5  feet thick, dense,  and moist.  Underlying this sandy clay
unit is a dense dolomite layer.

Hvdrogeology.   In the  area of  investigation,  there are  three water-bearing
systems: (1) the  surficial  aquifer,  (2)  the  intermediate aquifer, and (3)  the
Floridan aquifer  system.   Between each system is  an aquitard (less permeable
unit).  Only the surficial aquifer was investigated at Site 7.

The surf icial aquifer is unconf ined and composed of fine- to medium-grained sand,
with minor amounts of silt and clay stringers.  These geologic deposits extend
to  approximately  85 feet  bis and  are underlain by  clay and  dolomite.    The
surficial aquifer is considered to behave as one hydrological unit.

The water cable  in the surf icial aquifer is typically between 5 and 10 feet bis.
Groundwatar flow  is  generally to  the  northwest,  toward Lake  Fretwell,  at an
average rate  of  19  feet per year.   Water  elevation data  indicate  that  the
vertical flow direction is  downward at Site  7 and is predicted (based on U.S.
Geological Survey data)  to be upward off site in the vicinity of Lake Fretwell.

Contaminant Sources.  The primary  source of contamination at  Site  7  was  the
liquid wastes,  i.e., waste solvents, paints and paint thinners, and fuel, used
to ignite aircraft frames.   Training activities have  ceased and  waste materials
are not stored at  Site 7; therefore, there is  no source for continued contamina-
tion at the site.

RI Results.  RI  activities were conducted by ABB-ES during the fall of 1994,  the
spring of 1995,  and the  summer of 1997  to  characterize the nature  and extent of
contamination at  Site  7.  Environmental  samples  for laboratory analysis were
collected  from  surface  soil,  subsurface  soil,  and  groundwater.   Analytical
results  indicated  the   presence  of  volatile  organic  compounds  (VOCs)   and
semivolatile organic compounds (SVOCs), as well as  inorganics,  in  surface soil,
subsurface  soil,  and groundwater.   A  summary of  analytical results  for each
medium is presented below.

Surface Soil Analytical Results.  The  results of the  confirmatory  surface soil
sampling program indicate the presence  of  a group of SVOCs, polynuclear aromatic
hydrocarbons  (PAHs), total  recoverable  petroleum  hydrocarbons  (TRPH),   and
inorganics.  PAHs and TRPH were detected  in  the  grassy  areas adjacent to  the
asphalt training area, in the vicinity of the training pit, grassy areas parallel
to  the old flightline  and at the end  of  the  old  flightline.   Inorganics were
detected  at one location  south  of the training  area and in  the grassy area
adjacent to the northwest corner of the old flightline.   The  highest concentra-
tions  of  PAH,  TRPH, and inorganics were  detected in the grassy area at  the
northwest corner  of  the  old  flightline.

One detection of lead, 178,000 milligrams per kilogram  (rag/kg) at sample  location
CF7SS12  (Appendix  A) ,   was  interpreted   not  to  be  representative  of  site
conditions.  Additional samples  were collected adjacent  to and beneath sample

 noncancer HI for a child resident is 2  (Figure 2-8), with antimony,  TRPH,  and
 arsenic contributing most of the risk.

 Subsurface Soil. The BRA indicates that the compounds detected in subsurface soil
 do not pose an unacceptable risk to  human receptors.

 Groundwater.   The BRA indicates  that compounds in  groundwater pose no  current
 human health risks at Site  7.   Under a future land-use scenario, a  noncancer
 human health  risk would be posed if the  groundwater  were used as a potable  water
 supply.    The HI  for a resident child  is 2  (Figure  2-9)  and is posed by  the
 presence of benzene,  iron,  aluminum,  and antimony*in  groundwater.

 Ecological Assessment.  Ecological risk  was assessed to  exist  for small  mammals
 and terrestrial plants at Site 7 due to the presence of lead  in surface  soil.
 The risk  is  assessed  to have  a low  probability  of  sub lethal effects  from
 ingestion or uptake of the lead.   The risk is over estimated; however, due Co the
 concentration of 178,000 mg/kg  at sample location CF7SS12.   Additional  soil
 sample data adjacent  to and beneath the CF7SS12 location indicate that the lead
 concentration is anomalous  and not representative of  site conditions.

 Ecological risk was not  assessed for subsurface soil  or groundwater contamina-
 tion.
2.7  DESCRIPTION  OF ALTERNATIVES.  This  section  provides  a narrative of each
alternative  evaluated.    Alternatives  were developed  for surface  soil and
groundwater.  No other media contain contaminants  above risk-based levels.  The
FS for OU 3 (ABB-ES, 1997a) and the technical memorandum for Site 7 surface soil
(TetraTech NUS, 1998)  gives  further information or.  the remedial  alternatives.

2.7.1  Surface Soil Alternatives  Two  alternatives  were developed and analyzed
for Site 7 surface  soil contamination.  They include 7SS1,  No Action, and 7SS2,
Soil Excavation and Disposal.

7SS1. No Action.  Evaluation of the No  Action alternative is required by  law and
provides  a  baseline against which  other alternatives can  be  compared.   This
alternative will involve leaving the site the way Lc  exists today, relying on the
organic contaminants to degrade naturally over time.  Chemical-specific ARARs
would not be met in the short term.  Ecological and human health risks would not
be immediately  reduced.  Contaminant  toxicity, mobility,  and  volume would be
reduced only over time.  Because there is no action, alternative  7SS1 is easily
implemented.  There are no capital costs  associated with 7SS1.

7SS2 . Excavation and Disposal.   This alternative involves removing approximately
3,901 yd of contaminated soil (above residential land-use cleanup criteria) from
the site and disposal of the excavated soil at an eligible landfill.  Areas where
surface soil  will be excavated are shown in Appendix A.   Clean soil will be
placed in the excavated area, seeded, fertilized, and covered with hay or straw.
Chemical-specific ARARs would  be  met and  ecological and human health risk will
be immediately reduced.  Excavated soil will be contained and characterized as
either hazardous  or nonhazardous.  If necessary,  the  soil  will be treated to
reduce toxicity before  disposal.  This alternative  is relatively easy to

 implement, requiring a backhoe and transport equipment.  Capital cost associated
 with this alternative is $568,000.

 2.7.2  Groundwater Alternatives  Two alternatives were analyzed for Site 7.  They
 include 7GW1,  No Action, and 7GW2,  Annual Monitoring.

 7GW1. No Action.  Evaluation of the No Action alternative is required by law and
 provides a baseline  against  which other  alternatives  can  be compared.   This
 alternative will leave the  site the way it exists today, relying on the  organic
 contaminants  to degrade naturally over time.  Chemical-specific  ARARs will not
 be met in the  short  term.   Human health risk would be immediately  reduced by
 restriction of groundwater  use.   Groundwater-use  restrictions would be  imposed
 by deed restrictions  or  land-use plans  and property deeds.  A  formal  request
 would be made  to  agencies administering the well installation permit program in
 Duval County to not issue permits for installation of drinking water wells that
 would pump water  from the shallow aquifer.  Contaminant toxicity, mobility, and
 volume could be reduced only over time, but the processes will not be monitored.
 The effectiveness and permanence of this alternative,  therefore, will be unknown.
 Because there  is  no action,  alternative  7SS1 is easily  implemented.   There are
 no capital costs  associated with  7SS1.

 7GW2. Annual Monitoring.  This alternative will require monitoring of contaminant
 concentrations and  degradation processes as well as restricting groundwater use.
 The final selection  of wells for  annual monitoring will  be provided in the
 remedial design for Site 7.  Human health risk will be immediately  reduced by
 groundwater-use restrictions (as described in the No Action alternative 7GW1) and
 eventually by  the degradation processes.   Over time, the toxicity, mobility, and
 volume  of the contaminants will be reduced.   Site conditions will be reviewed to
 assess  the progress  of  this RA.    This alternative  is   relatively easy to
 implement, requiring  sampling equipment and materials,  laboratory analysis, and
 containment of purge  water  and waste  materials.   Capital costs associated with
 this  alternative  are  $137,000  over  a  30-year period.


 2 . 8   SUMMARY OF COMPARATIVE ANALYSIS OF ALTERNATIVES .  This section evaluates and
 compares  each  of  the  alternatives with respect to  the nine  criteria outlined in
 Section 300.430(s)  of the NCP (USEPA, 1990). These criteria are  categorized as
 threshold, primary balancing,  or modifying.  Table  2-1 gives explanations of the
 evaluation criteria.

 A  detailed analysis was performed on the alternatives using  the nine  evaluation
 criteria  in order to select a site  remedy.  The following  is a  summary of the
 comparison of  each  alternative's strength and weakness with respect to the nine
 criteria.  Table  2-2 presents the evaluation of contaminated surface soil and
 groundwater remedial  alternatives.


 2.9   SELECTED  REMEDIES.  Two remedies were selected to address the contaminants
 in the  surface soil and groundwater at Site 7.   For surface  soil, alternative
 7SS2, Excavation  and Disposal was selected.  For groundwater,  alternative  7GW2,
Annual  Monitoring,  was selected.

2.9.1  Site 7 Surface Soil The  selected alternative,  Excavation and Disposal,
requires the removal of contaminants of concern from the site.  Excavated soil
will be  characterized  and disposed of  in  either a subtitle D  or  C landfill,
depending on soil characteristics.  The excavated area will be backfilled and
revegetated. The estimated cost from this alternative is $568,000 and will take
approximately 10 days to complete.  This  alternative was selected because it will
immediately remove the contaminants of concern, reduce the toxicity, mobility,
and volume of the contaminants, will have a long-term effect on the  site, and is
relatively easy to implement.

2.9.2  Site 7 Groundwater  Much of the risk from groundwater is derived from a
single  detection of benzene.   The  selected alternative,  annual  monitoring,
provides a method of observing the fate  and any migration of benzene over time.
Groundwater use from the surficial  aquifer at Site 7 will be restricted, thereby
providing  immediate  protection  to human health.   This  alternative  provides
monitoring every 5 years until cleanup goals  are  achieved.  During  each review,
site conditions will be reassessed and monitoring continued or other appropriate
actions taken.

2.10 INSTITUTIONAL CONTROLS.   The goals  of institutional controls at Site 7 are
to protect human health and the environment by limiting exposure to groundwater
to  prevent  unacceptable   risk.     The   institutional  controls will  prevent
exposure/consumption of groundwater that exceeds State and Federal drinking water
standards.

Institutional controls will  be  implemented by the use of deed  restrictions to
restrict the installation  of  groundwater wells and extraction of groundwater for
potable  and nonpotable use,   or  other activities which  may  cause  exposure to
groundwater contaminated above regulatory standards; notice to  local agencies;
regular  inspections; and through 5-year reviews  as  required by  CERCLA.


2.11 STATUTORY DETERMINATIONS. The remedial alternatives selected for Site  7 are
consistent with CERCLA and the NCP.  The selected remedy provides protection of
human health and  the environment,  attains ARARs,  and  is  cost affective.  Table
2-3  lists  and  describe Federal  and State requirements  to which  the selected
remedy  must comply.   The  selected  remedy  consists of permanent solutions and
alternative  treatment  technologies  to the  maximum  axzent  practicable  and
satisfies the statutory preference for remedies that reduces toxicity, mobility,
or volume as a  principal element.  The selected remedy also provides flexibility
to  implement additional  remedial  measures,  if necessary,  to  address RAOs or
unforeseen  issues.


2.12 DOCUMENTATION  OF  SIGNIFICANT  CHANGES.  The  Proposed Plan  for Site 7 was
released for public comment  in October 1997.   The Proposed Plan  contains the
alternatives that were  selected for soil  and groundwater remediation: Alternative
7SS2, soil excavation and  disposal, and  alternative  7GW2, annual monitoring.  No
significant changes to the remedy, as originally identified in the Proposed Plan,
were necessary.

Rorida Surface Water Quality Standards
(FAC, 62-302)
Jacksonville, Florida
Description
Defines the listed and characteristic hazardous wastes
subject to RCRA. Appendix II contains the Toxlclty
Characteristic Leaching Procedure.
The Act requires Federal agencies to take action to avoid
jeopardizing the continued existence of federally listed
endangered or threatened species.
Establishes ecological and health-based Federal
Ambient Water Quality Criteria (AWQC) that are non-
enforceable guidelines used by states to set their state-
specific water standards for surface water.
Requires Federal agencies to consider the existence and
location of landmarks on the National Registry of Natural
Landmarks to avoid undesirable Impacts on such land-
marks.
Establishes enforceable standards for potable water for
specific contaminants that have been determined to
adversely affect human health.
Adopts by reference sections of the Federal hazardous
waste regulations and establishes minor additions to
these regulations concerning the generation, storage,
treatment, transportation, and disposal of hazardous
wastes.
Rule distinguishes surface water Into five classes based
on designated uses and establishes ambient water quality
standards (called Florida Water Quality Standards) for
listed pollutants.

Consideration In the
Remedial Action Process
These regulations would apply when deter-
mining whether or not waste onslte Is hazard-
ous, either by being listed or exhibiting a
hazardous characteristic, as described In the
regulations.
If a site Investigation or remediation could
potentially affect an endangered species,
these regulations would apply.
These AWQCs may be used as a basis for
determining cleanup levels In the absence of
State water quality standards.
Prior to remedial activities onslte, Including
remedial Investigations, the existence of
Natural Landmarks must be Identified.
MCLs can be used as protective levels for
groundwaters or surface waters that are
current or potential drinking water sources.
These regulations would apply If waste onslte
Is deemed hazardous and needs to be
stored, transported, or disposed of,

Because these standards am specifically
tailored to Florida waters, they should be
used to establish cleanup levels rather than
the Federal AWQC.

Rorida Groundwater Guidance,
Bureau ol Groundwater Protection,
June 1994.
Rule designates the groundwaters of the State Into five
classes and establishes minimum "free from"  criteria.
Rule also specifies that Classes I & II must meet the
primary and secondary drinking walei standards listed
in Chapter 62-550.
Rule adopts  Federal primary and secondary drinking
water standards.

Establishes a cleanup process to  be followed at all
petroleum-contaminated sites.  Cleanup levels for the
G-l and G-ll groundwater are provided in the gasoline
and kerosene/mixed product analytical groups.
The document provides maximum concentration levels
of contaminants for groundwater in the Slate of Florida.
Groundwater with concentrations lass than the listed
values are considered "free from" contamination.
