SYNOPSIS
BACKGROUND
Public Law 92-500 authorizes the United States Environmental Protection Agency (EPA) to be the ad-
ministering agency for a major Federal environmental program entitled "Grants for Construction of
Treatment Works". Under this program, the EPA Administrator may provide up to 75 percent of the
funding for the construction of publicly-owned wastewater treatment facilities to any qualifying state,
municipality, intermunicipal agency, or interstate agency. Before granting federal funds, the National
Environmental Policy Act (NEPA) and Executive Order 11514 require all federal agencies to prepare En-
vironmental Impact Statements (EIS) on any projects which may significantly affect the quality of the
environment or may be highly controversial.
EPA Region III has prepared this EIS to assess the environmental impacts associated with the proposal
of the Hampton Roads Sanitary District (HRSD) to construct a 15 million gallon per day (mgd) sewage
treatment plant (STP) on the York-James Penninsula immediately west of Seaford, York County,
Virginia.
The Facilities Plan for the proposed project was completed in 1975 and forwarded to the Virginia State
Water Pollution Control Board (SWCB) for the required state certification before EPA could finally ap-
prove the construction grant application. During the SWCB review, EPA received copies of the Facilities
Plan for internal review. After careful review and consideration, EPA, on March 31, 1976, published a
Notice of Intent to prepare an EIS. As a result of a competitive review, Ecol Sciences, Inc. was contracted
by EPA to prepare the EIS. Preparation of the Draft EIS was made available for public review on May
19, 1977 and a public hearing to solicit comments concerning the Draft EIS was held on June 20, 1977.
This Final EIS addresses the comments received during the review period of the Draft EIS in an issue-
oriented manner and references the Draft EIS as an appendix.
DESCRIPTION OF THE APPLICANT'S PROPOSED PROJECT
HRSD has proposed to construct a 15 mgd conventional sewage treatment plant by 1980. A simple
schematic of a typical secondary wastewater treatment is shown below. Effluent from the facility would
be chlorinated, dechlorinated, and discharged to the York River through the cooling water discharge of
the nearby Virginia Electric Power Company (VEPCO) electric generating station. Capital costs for the
York River STP were estimated to be $20,031,000 and initial operation and maintenance costs for the
facility were estimated to be $673,000 by GFCC in 1977.
The service area of the proposed York River STP encompasses an area of approximately 69,400 acres and
would include most of York County, the City of Poquoson, and the northern half of the City of Hampton.
HRSD currently operates three municipal sewage treatment plants on the York-James Peninsula. These
facilities, Boat Harbor, James River, and Williamsburg, are connected by a series of force mains, pum-
ping stations, and interceptors. The "interconnect" system was designed to permit HRSD to avoid the
discharge of untreated wastewater by diverting flows from an overloaded or malfunctioning facility to
another facility in the system for treatment until the problem at the first facility could be corrected. The
ability to transfer flows between service areas is regulated by the capacities of the conveyance system
and the excess treatment capacity of the connected treatment facilities. In its review of wastewater
management alternatives for the York-James Peninsula, the Virginia State Water Control Board
(SWCB) recommended that the York River STP be included in the interconnect system.
The plant service area is included in the Hampton Roads Air Quality Control Region (AQCR). Two air
pollutant sources in the immediate vicinity of the proposed facility, VEPCO and the Amoco refinery,
emit more than 90 percent of the sulfur dioxide (S02), particulates, and carbon monoxide (CO) emitted in
York County. Both of these sources are currently in compliance with air quality regulations. Odorous
pollutants are a problem in the immediate vicinity of the proposed facility. VEPCO and Amoco are the
probable sources of the these pollutants.
Water quality in the lower York River generally conforms with state water quality standards.

Closures of shellfish harvesting areas have occurred in tributaries to the lower York River and around
small sewage outfalls. These closures have been related to contamination from small STP's, marinas, ur-
ban runoff, and failing septic tanks.
Aquatic animals of commercial importance include: the blue crab, the hard clam, and numerous fish
species. No known endangered plants occur within the primary study area. No endangered animal
species have been recently reported in the study area, but endangered or undetermined species which
may utilize the area for feeding include the southern bald eagle, the osprey, and the Peregrine falcon.
SOCIAL AND ECONOMIC ENVIRONMENT OF THE STUDY AREA
In 1975 the population of the service area of the proposed York River STP was 80,902. Approximately 60
percent of the population was concentrated in the City of Hampton which is the urban center of the study
area. Approximately 6 percent of the 1975 population was housed on military reservations. The cities of
Hampton and Poquoson are the major developed portions of the study area. In contrast, lower York
County is principally rural.

The economy of the study area is highly dependent, both directly and indirectly, upon federal govern-
ment expenditures. Military employment includes 23,000 military and 15,000 civilian personnel. The
Newport News Shipbuilding and Drydock Company employs approximately 24,500 persons for federal
contract construction. Agriculture is not a significant contributor to the Peninsula economy. York Coun-
ty and Poquoson are "bedroom" suburbs of the Newport News-Hampton economic center. Commuting
patterns in the area have been dictated by tolls on the major access routes. The recent removal of these
tolls may significantly alter previous growth patterns in the area.
Three public services appear to control development in the study area: sewage treatment capacity, water
supply, and transportation. The applicant's proposed project is designed to provide adequate sewage
treatment capacity for future growth. Water is supplied to the study area by the Newport News Water
System. The safe yield of this system, with the completion of the Little Creek Reservoir during 1976, is
approximately 65 mgd and is sufficient to satisfy water requirements to the year 2000. Development in
the York County Portion of the study area has concentrated along major transportation routes or near
the York River.
The study area is rich in history and contains 50 sites of historic value. Twelve of these sites are included
in the National Register of Historic Places. None of the National Register sites will be directly affected
by the proposed project. The Virginia Research Center for Archaeology has stated that the proposed site
for the York River STP has a high potential for containing prehistoric relics. The applicant is currently
evaluating the archaeological potential of the site. The study area contains 9,191 acres of wetlands.
STATUS OF COMPREHENSIVE PLANNING
Three regional planning agencies have jurisdiction in the study area:
Peninsula Planning District Commission (PPDC)
Hampton Roads Sanitation District (HRSD)
Hampton Roads Water Quality Agency (HRWQA)
These agencies coordinate the planning activities of the municipalities on the York-James Peninsula. The
municipalities are empowered by the state to plan and zone for future development within their boun-
daries. York County adopted the land use plan included in its Comprehensive Plan in 1976. That plan
projects that York County will remain a residential suburb of the Newport News-Hampton economic
center. Poquoson became a City in 1975 but has been planning land use since 1952. The present land use
plan envisions additional development of residential, commercial and industrial sites with minimal in-
fringement upon conservation areas. Hampton adopted a land use plan in 1971. The plan projects con-
tinued dominance by residential development. The plan also projects a significant area of land for public
use. Projections of future land use in the service area of the York River STP are summarized below:
Percent of
Projected Land Use Acres Total Area
Residential 23,115
Commercial 1,394
Industrial 1,712
Public/Semi-public 7,588
Vacant/Conservation 27,739
Reserved 4,651
Water Areas 872
69,071 100.0
The principal local growth controls available to the municipalities in the study area are zoning and sub-
division ordinances, capital improvements programs, and open space and recreational planning. York
County's current zoning ordinance is not in compliance with the goals of the 1976 land use plan. The
County has recognized the discrepancies between these two documents and is initiating a comprehensive
rezoning process. The County zoning ordinance was not adequately enforced during the past eight years.
York County's capital improvements budget is currently insufficient to provide adequate facilities if
-------
rapid growth should occur in the County. York County identified a series of "Open Space/Conservation"
areas in the 1976 land use plan. The County is currently identifying alternative methods of preserving
these areas. The zoning ordinance of the City of Poquoson conforms with the most recent land use plan.
Enforcement of, and adherence to, the zoning ordinance has been strict. The rate of capital improvement
expenditures in Poquoson will decline during the next five years but will be sufficient to maintain essen-
tial services. Open space and recreation planning in Poquoson is limited and all planned facilities are
designed for local use. The City of Hampton has strictly enforced its zoning ordinance. When the new
land use plan for the City is adopted, the zoning ordinance will be amended to include new land use
policies. The capital improvements program for the City of Hampton includes significant expansion of
public facilities. Open space and recreational facilities are included in the City's land use plan and capital
improvements program.
Environmental Evaluation of the Applicants Proposed Project
The principal, primary, long term impact of the applicant's proposed project will be an increase in point
source pollutant loading of the York River. However, based on the Hydroscience model, this increased
loading should have only a minimal impact. The increased air pollution load generated by incinerating
the sludge from the facility will not violate any primary or secondary air quality standards. Secondary
impacts of the applicant's proposal are generally minimal. These impacts are mitigated, in part, by the
presence of large areas of open space in York County, local ordinances for growth management and the
protection of environmentally sensitive areas, and the concentration of growth in the cities of Poquoson
and Hampton. The principal beneficial effects of the proposed project are the provision of capacity to
allow treatment of sewage now being undertreated by individual septic tanks and to allow orderly
growth with minimum environment impact.
ALTERNATIVES TO THE APPLICANT'S PROPOSED PROJECT
EPA has reviewed the applicant's proposed project and has determined that the proposed treatment
processes are acceptable and will achieve the required degree of treatment. Chlorination and dechlorina-
tion will provide the required disinfection and remove residual chlorine from the effluent. Advance waste
treatment units are not required at the proposed facility.
HRSD has proposed incineration as a sludge-volume reduction technique. Because the study area is in-
cluded in an Air Quality Control Region (AQCR), EPA has questioned the continued reliance upon in-
cineration. Sludge disposal through land application appears feasible because large areas of open space
are included in the military bases and parks on the York-James Peninsula. Composting also appears to be
a feasible sludge disposal technique.
EPA has reviewed the alternative of constructing a regional facility at the existing James River Facility.
EPA has also investigated the use of staged construction of such a regional facility. Neither of these
alternatives offer a cost savings over the applicant's proposal to construct the York River Plant.
Continued reliance upon septic tanks for sewage disposal in the York County portion of the service area is
not practical because minimum lot sizes are too small for septic tanks, and most of the land is unsuitable
for septic tanks.
Thus, the No-Action alternative would have significant adverse impacts upon growth in the service area
and could promote adverse impacts upon water quality.
Summary Recommendations
EPA's review of population forecasts, wastewater flows and economic projections for the service area in-
dicates that 15 mgd would provide applicant with sufficient treatment capacity to alleviate existing
water quality problems in the service area and to accommodate projected wastewater flows for a short
period of time in excess of the 1995 design year.
EPA's analysis has taken into consideration the most recent State of Virginia population figures and also
assumed that residential per capita water use will remain at 62.7 gallons per capita per day throughout
-------
the design life of the plant. Providing treatment capacity in the system for infiltration and inflow has
been determined to be more cost-effective than embarking on a rehabilitation program.
Sludge disposal techniques need further evaluation by HRSD. Thus, EPA will condition the construction
grant application to provide for the evaluation of land application as a sludge disposal alternative.

Administrative (X)
Legislative ( )
2. The Hampton Roads Sanitation District (the applicant) has requested Federal financial assistance for
the construction of a 15 million gallon per day (mgd) wastewater treatment facility to be located near
v Seaford, York County, Virginia. Federal financial assistance has been requested under the statutory
authority of the Federal Water Pollution Control Act Amendments of 1972 (PL 92-500). The service
area of the proposed facility includes York County, the City of Poquoson, and the northern half of the
City of Hampton. However, because the applicant's sewage treatment facilities are interconnected,
the service area of the proposed facility could be extended to other areas of the York-James Peninsula.
The proposed project does not include the development of a collection system, but two collection
systems are being development of a collection system, but two collection systems are being developed
in the service area.
3. The proposed facility was designed to alleviate public health hazards, to improve water quality, and to
promote orderly growth in the service area. The proposed facility was also designed to satisfy the pro-
jected 1995 wastewater treatment requirements of the service area. EPA's review of population
forecasts, wastewater flows and economic projections for the service area indicate that 15 mgd would
provide the applicant with sufficient treatment capacity to alleviate exisiting water quality problems
in the service area and to accommodate projected 1995 wastewater flows. The applicant's proposed
future wastewater flows incorporate a 12.4 gcd increase in residential flows between 1980 and 1995;
capacity will be provided only for maintenance of the 1980 projected consumption of 62.7 gcd, ad-
ditional increases are not justified.
Minor short-term adverse impacts will occur during construction of the proposed facility. These
construction-related impacts will result in increased noise levels, dust and air pollutant concen-
trations, and sedimentation and erosion. These adverse impacts will be concentrated near the site of
the facility and along the outfall corridor, and can be minimized through sound conservation practices
and contemporary construction techniques.
Long-term primary impacts of the applicant's proposed project include substantially increased pollu-
tant loading of the lower York River and increased air pollution loading resulting from incineration of
the sludge from the facility. However, according to the Hydrosciences, Inc. (1975) modeling of the
lower York River, the proposed discharge would have minimal adverse impact upon the water quality.
Further, no primary or secondary air quality standards would be violated.
Secondary environmental impacts resulting from the applicant's proposed project include increased
air and water pollution from area sources, blockage of groundwater recharge areas, increased
demands for water, recreational facilities and other public servcies, and encroachment upon historic
and archaeological sites. Many of these secondary impacts may be minimized as a result of local or-
dinances to manage growth and protect environmentally sensitive areas, the presence of substantial
areas of land which cannot be developed (military reservations and the Yorktown National Battlefield
Park), and the concentration of future growth in the cities of Poquoson and Hampton. EPA's effort
has been directed toward the preservation of environmental quality as it is affected by secondary im-
pacts resulting from land use, and social and economic development of the service area. As part of this
analysis, EPA has evaluated the status of each municipality's land use plan, comprehensive plan, and
zoning ordinance. EPA has also identified environmentally sensitive areas which require protection
through strong local ordinances (existing and revised) while managed development proceeds.
4. EPA analyzed numerous alternatives to the applicant's proposed project. These alternatives were
assessed on the basis of environmental and socioeconomic information contained in this statement.
iii
-------
Alternatives evaluated by EPA ranged from specific treatment processes to the concept of
regionalization at other existing facilities in the interconnect system. Non-structural alternatives and
the no action alternatives were also evaluated.
Several mitigating measures would permit the applicant to avoid some of the adverse primary and
secondary environmental impacts of the proposed project. EPA is providing assistance to the appli-
cant in the further development and implementation of these measures.
5. A public hearing on the York River STP Draft EIS was conducted on June 20,1977 at 6:30 PM in Tabb
High School Auditorium in York County. A list of persons appearing or submitting comments for the
record is included following this summary. Persons submitting written comments on the DEIS are
also listed.
6. This Final EIS addresses issues and errors raised through written comments, appearances at the
public hearing, and by new information developed since publication of the Draft EIS. Additionas 01
new information and corrections of errors are contained in Appendix B in the form of errata. Substan-
tive issues are discussed under the appropriate heading in the body of the EIS. Issues discussed are

I. DESCRIPTION OF THE APPLICANT'S PROPOSED ACTION
A. BACKGROUND
No substantive issues were raised since publication of the Draft EIS which were related to this sub-
ject. Therefore, for a discussion of this subject, refer to page 1-1 of the Draft EIS, Appendix A (not in-
cluded).
B. EXISTING WASTEWATER TREATMENT FACILITIES
No substantive issues were raised since publication of the Draft EIS which were related to this sub-
ject. Therefore, for a discussion of this subject, refer to page 1-4 of the Draft EIS, Appendix A (not in-
cluded).
C. APPLICANT'S PROPOSED PROJECT
No substantive issues were raised since publication of the Draft EIS which were related to this sub-
ject. Therefore, for a discussion of this subject, refer to page 1-18 of the Draft EIS, Appendix A (not in-
cluded).
The Hampton Roads Sanitation District (HRSD) has extended sewer service to the entire York-
James Peninsula by realigning the boundaries of its three existing sewer service areas and constructing
the York River Sewage Treatment Plant. The site of the proposed York River STP is located west of
Seaford in York County, Virginia, on the southern bank of Back Creek. The site is included on the USGS
"Poquoson West" topographic quadrangle and is located within the 100-year flood plain of Back Creek.
Through this action, the applicant proposes to implement the recommendations of the following studies:
Water and Sewage Facilities Plan, Malcoln Pirnie, Inc. (1969),
Interim Metropolitan/Regional Water Quality Management Plan, Malcolm Pirnie, Inc. (1971),
Lower James River Comprehensive Water Quality Management Study, Virginia State Water
Control Board, (1974),
York River Wastewater Treatment Plant Preliminary Engineering Report, Gannett, Fleming,
Corddry, and Carpenter (1974).
HRSD proposes to construct the York River STP with a capacity of 15 mgd and to use the conven-
tional activated sludge process. GFCC (1974) recommended to HRSD that the wastewater treatment
facility include unit processes for degritting, primary clarification, singlestage activated sludge aeration,
secondary clarification, disinfection by chlorination, gravity thickening of primary sludges, anaerobic
digestion, vacuum filtration, and incineration. However, based upon a cost-effectiveness analysis of in-
cinerator capacities at its existing facilities, HRSD decided not to construct an incinerator at the York
River STP.
Sludge from the proposed facilities will be disposed of in the existing incinerators at the Boat Har-
bor STP. Dechlorination was also included in the design after the SWCB adopted the position that
dechlorination facilities should be provided at the proposed facility. Dechlorination will be accomplished
through the addition of sulfur dioxide (S02) to the effluent.
The conventional activated sludge process biologically stabilizes wastewater through the metabolic
activities of microorganisms in an aerobic environment. Single-stage activated sludge aeration is design-
ed to remove carbonaceous oxygen demand, but some nitrification may occur depending upon operating
conditions. Operating at 15 mgd the proposed facility would receive daily loads of 26,900 Ibs. of BOD and
29,400 Ibs. of suspended solids. Removal rates for BOD and suspended solids would be 86 percent and 87
percent respectively (GFCC, 1976, Personal Communication). Total phosphorus and total nitrogen
loading of the facility would occur at rates of 1,250 Ibs. and 5,000 Ibs. per day, respectively. Removal rates
for these constituents will be 20 and 12 percent, respectively.
1-1
-------
Influent sewage to the York River STP will be screened before flowing through the grit collectors
(detntors). The degritted waste will flow into the primary clarifiers, which will remove most inorganic
suspended solids and some of the larger, denser organic suspended solids. Settled wastewaters will then
flow into aeration tanks where biologically active microorganisms (activated sludge) will be maintained.
The mixture of sewage and secondary clarifier sludge, "mixed liquor", will be turbulently mixed in the
aeration tanks. This will permit the microorganism to efficiently degrade the carbonaceous matter in the
waste and convert it into more biomass. The mixture of bacteria and wastes produced in the aeration
tanks will flow into the secondary clarifiers where the bacteria and other solids will settle out of suspen-
sion. Some of the sludge from this process will be returned to the aeration tanks to maintain the
necessary biological population for optimum treatment. The remainder of the sludge will be diverted to
the sludge digester. Treated wastewater will flow over the weirs of the secondary clarifiers and will enter
the chlorination units for disinfection. The disinfected effluent will flow through dechlorination units
before being conveyed to and through the VEPCO outfall into the York River.
Since the plant discharges into shellfish waters, it will be of Class I reliability, that is, auxiliary
electrical power will be required so that the plant car operate in the event of a power failure.
Sludge from the primary clarifiers will be thickened by gravity. Sludge from the secondary
clarifiers will be thickened by flotation. The thickened sludges will be stabilized through anaerobic diges-
tion. During this process the facultative bacteria will utilize the organic wastes for food and produce
volatile organic acids. The anaerobic bacteria will convert most of these acids to methane and carbon
dioxide. This process will reduce the mass and volume of sludge, reduce the number of pathogenic
organisms, and provide a useful by-product (methane). After digestion, the sludge will be dewatered on
vacuum filters. The filtrate will be returned to the process flow. The dewatered sludge, which is ap-
proximately 22 percent dry solids by weight, will be collected from the filters and will be disposed of in
the existing incinerators at the Boat Harbor STP.
No substantive issues related to this subject have been raised since the publication of the Draft EIS.

In the Draft EIS on Page 11-24 in Figure II-4 flood-plains are shown incorrectly. This was pointed
out by Hampton Roads Sanitation District (HRSD) in written comments dated June 18,1977 (Appen-
dix E). The correct outline of the 100-year floodplain at the proposed site of the York River STP is
shown in "Exhibit E," an attachment to the forementioned letter. This information indicates that suf-
ficient area above the 100-year floodplain is available for the necessary structures.
Issue: Acceptability of soils on site for necessary structures
This issue was raised by the Chespeake Bay Foundation in their statement at the public hearing
held June 20, 1977 (Appendix E). Page 11-23 of the Draft EIS indicates that soil associations] iden-
tified by SCS on the proposed STP site are classified as exhibiting severe and moderate limitations
for construction of roads or structures. However, it must be recognized that SCS assessments of the
limitations of soil types are generalized to an entire soil group; a much more accurate assessment of
soil capabilities on a site can be gained by performing and analyzing soil borings. "Attachment A" to
HRSD's letter of July 18 (Appendix E) indicates the engineering firm of Gannett, Fleming, Corddry,
and Carpenter performed an investigation of foundation conditions at the site including core borings
and soil tests which established the acceptability of the site for the proposed types of structures.

IV. ENVIRONMENTAL EVALUATION OF THE APPLICANTS PROPOSED PROJECT
A. ENVIRONMENTAL IMPACTS OF THE APPLICANT'S PROPOSED PROJECT
The following substantive issues related to environmental impacts at the applicant's proposed project
were raised through comments or new developments since publication of the Draft EIS.
Issue: Salinity verification of Hydroscience model
The Virginia Institute of Marine Science (VIMS) in comments dated August 15,1977, (Appendix E)
questioned the salinity verification of the model prepared by Hydroscience, inc. to assess water quali-
ty effects of the proposed York River STP. EPA concurs with the model's theoretical shortcomings as
raised by VIMS; however it is felt that the model is sufficiently accurate for the purposes of analysis
and that improvement would involve extensive research efforts beyond the needs and scope of this
EIS.
Issue: Ground water export via effluent
The U.S. Department of the Interior in their letter of July 14,1977 (Appendix E), raised the ques-
tion of possible ground water depletion through the export of domestic well water in the STP effluent
which had previously recharged to the ground water through septic tanks. The Chesapeake Bay
Foundation, York Chapter, also raised this issue in their public hearing comments on June 20, 1977
(Appendix E). However, sewer and water service are most often provided together and for this reason
as service becomes available the quantity of ground water extracted from individual domestic wells
will decrease reducing the impacts of removing septic tank recharge. For this reason, ground water
export via STP effluent will not be a significant problem.
Issue: New data on the Boat Harbor incenerators
At the time the Draft EIS was prepared no emissions data were available for the Boat Harbor STP
incinerators. Estimates of particulate concentrations in the Draft EIS due to incineration of sludge
assumed emissions from the incinerators would be 1.3 Ib/dry ton sludge which is the applicable New
Source Performance Standard (NSPS).
Since the Draft EIS was released, the Boat Harbor incinerators have completed compliance tests
for particulate emissions. Average particulate emissions were 0.545 Ib/ton dry sludge for Furnace #1,
and 0.572 Ib/ton dry sludge for Furnace #2. These values are less than 45% of the applicable NSPS.
Therefore, the actual impact of particulate emissions will be lower than predicted in the DEIS as
shown in Table IV-1, below:

Issue; Economic impact of shellfish closure zone
VIMS, in their letter of July 21,1977, (Appendix E) questioned the conclusion of the Draft EIS that
because of MSC the shellfish closure zone necessary around the effluent discharge point would not
cause significant economic impacts. This disease currently renders the affected beds unprofitable.
VIMS pointed out that research is currently underway to produce an MSX-resistant variety of oyster.
They felt this potential was not recognized by the EIS. While such research is currently underway at
VIMS, no natural plantings have yet been successful. In the event that a resistant strain is developed
which could support a commercial fishery in MSX-infested higher salinity waters, it will be necessary
to reevaluate the economic impact of the closure zone, based on oyster market values and operating
costs at that time. Steps to reduce the size of the closure zone may then be justified.
Issue: Growth inducement and the York River STP
The issue of the growth inducement effects of the proposed York River STP was raised by a number
of comments from citizens and governmental agencies. Letters from the U.S. Department of
Commerce (August 16,1977; Appendix E), Richmond Regional Planning District Commission (July 1,
1977; Appendix E), Mr. H. A. Ross-Clunis (July 21, 1977), and Mr. Fred Schaumburg (July 21, 1977)
raised this issue along with numerous persons at the public hearing on June 20, 1977, including Mr.
Paul Baker for the York Chapter of the Chespeake Bay Foundation, Ms. Elizabeth Rogers of the
Williamsburg Area League of Women Voters, and Mr. H. A. Ross-Clunis. Essentially, the assertion is
made that the proposed York River STP induces or attracts the growth on which basis it is justified.
The reader is referred to the discussion of accommodated and induced growth in the Draft EIS, page
IV-48 (Appendix A).
EPA has reviewed population projections used in sizing the York River STP and found them
reasonable. These conclusions are discussed in the Draft EIS beginning on pages 111-16 and V-5
(Appendix A). Recent changes in the Virginia Office of Planning and Budget population projections
are assessed in this Final EIS under Section V-A, Component Alternatives. Under this type of situa-
tion, where sizing of STP capacity is not excessive, local conditions and the availability and costs of
collectors will determine the potential for growth inducement.
As discussed in the Draft EIS (Appendix A) on page IV-37, without previous decisions regarding
public funding of collector sewers, growth inducement is difficult to tie to a reasonable increase in
regional treatment capacity. However, collectors are currently being installed in some limited
developed areas of Sanitary District #2 under EPA Contract # 510405 and may be extended into large
areas of partially developed land under EPA Contract # 510585. A map designating the areas of these
contracts is included as Figure 1-17 on page 1-28 of the Draft EIS (Appendix A).
In light of the preliminary indications of growth inducement potential discussed in the Draft EIS,
environmental assessment activities currently underway on EPA Contract # 510585 will fully con-
sider this issue. EPA Program Requirements Memorandum 77-8 (July 21, 1977, Appendix F) strictly
regulates funding of collector systems.
Collectors are eligible for funds only if they are built for a community having "substantial human
habitation" as of October 18, 1972, with adequate treatment capacity in existence or planned.
The memo states "that substantial human habitation is considered to be an average density of 1.7
persons per acre or one household for every two acres. Density is to be evaluated block by block or by
areas of five acres or less. Two-thirds of the flow design capacity of the collector must be for
wastewaters originating from the habitation. This two-thirds rule would apply to each area
evaluated. New collectors must also be necessary and cost-effective, as documented in facility plans,
and the public must be informed as to their cost. (Air/Water Pollution Report, 1977)."
This process will assure that collectors are not oversized, therefore do not promote induced growth.
In addition, planning for EPA Contract # 510585 will identify area by area the environmental and
cost factors related to decentralized on-site alternatives for waste treatment such as cluster systems
or sand mounds as well as conventional collection and centralized treatment. EPA feels this process is
adequate to deal with potentials for growth inducement in Sanitary District #2.

Issue: Water quality impacts
A number of comments compared projected adverse impacts of effluent with the beneficial impacts
of relieving existing problems with septic tanks. This issue was raised by many of the commentors
listed above as concerned about growth impacts. In addition, Mr. Bruce Flagge and Mr. Henry Elksin
voiced the same issue at the public hearing on June 20,1977. It is erroneous, however, to make this
comparison. In evaluating alternatives a comparison must be made between the minimal to moderate
impacts identified for the applicant's proposed effluent discharge and the severe impacts identified
for the no-action alternative. These impacts are discussed on pages IV-7 and V-26, respectively, of the
Draft EIS (Appendix A).
In addition, the public's concern regarded the potential non-point runoff-related water quality im-
pacts of projected growth. The Hampton Roads Water Quality Agency (HRWQA) is currently prepar-
ing an Areawide Waste Treatment Management (AWTM) Plan which has responsibility for examin-
ing non-point pollution from existing and future development and establishing workable manage-
ment strategies to control this pollution. Ms. Elizabeth Rogers, in her comments at the public hearing
on June 20,1977, for the Williamsburg Area League of Women Voters, suggested delaying the Final
EIS and planning for the York River STP until completion of this plan. However, it is EPA's position,
detailed in Program Requirements Memorandum 75-38 (February 9,1977, Appendix F) that ongoing
facilities planning should not be delayed for the completion of AWTM Plans.

V. IDENTIFICATION AND EVALUATION OF ALTERNATIVES TO THE APPLICANT'S
PROPOSED PROJECT
A. COMPONENT ALTERNATIVES
The following substantive issues related to component alternatives were raised through comments or
new developments since publication of the Draft EIS.
Issue: Effluent disinfection
Questions concerning alternative techniques for effluent disinfection and for dechlorination of
chlorinated effluent were raised by Mr. Paul Baker for the York Chapter of the Chesapeake Bay
Foundation at the public hearing on June 20, 1977, as well as by Mr. John Demerit and Mr. Allen
Sower.
As indicated by Table V-3, page V-5 of the Draft EIS, dechlorination with sulfur dioxide (S02) was
considered as an alternative. Sulfur dioxide dechlorination is a relatively simple process, similar to
chlorination, and highly effective in removing residual chlorine. A case of chlorinated effluents caus-
ing fish mortalities at the James River plant has been reported by Mellanca and Bailey (1975). In this
case, the problem was excessive use of chlorine for disinfection, and was resolved by better control of
the chlorination process. Due to such operational problems, both EPA and the SWCB are recommen-
ding that dechlorination be utilized as an environmental safeguard.
Although chlorine has a long record as a proven disinfectant for wastewater, it is suspected of reac-
ting with the residual organic material in the treated wastewater to form chlorinated hydrocarbons.
Dechlorination with sulfur dioxide (a reducing agent) removes residual chlorine but does not remove
chlorinated hydrocarbons. Ozone will not form chlorinated hydrocarbons, but it is not known if ozone
will react with organic material in wastewater to form other compounds in trace amounts. Little in-
formation exists to document the long-term impacts of either chlorination or ozonation on natural
water. As the vast majority of wastewater treatment plants disinfect their effluent with chlorine or
ozone, resolution of this issue is national in scope, and beyond the scope of this statement. In any
case, much of the basic disinfection equipment is the same for chlorine and for ozone, so installing one
process now would not preclude switching to the other at a later date, should more information
become available.
Issue: Class I reliability
The measures necessary for plant reliability to meet Class I reliability requirements for discharg-
ing in shellfish waters were not detailed in the Draft EIS. Class I reliability for the York River STP
will include multiple units and equipment, auxiliary power for essential plant elements, and
automatic alarms to give warning of high water, power failure, and equipment malfunction.
Chlorination must be continuous and the chlorine contact time will be half hour at peak flow with one
hour contact at average flow. This should provide 75-80% disinfection efficiency. Class I reliability
will eliminate all raw sewage bypasses and assure consistently a minimum of primary treatment
with chlorination.
Issue: Sludge disposal by incineration in an AQMA
This issue, raised by Ms. Elizabeth Rogers for the Williamsburg Area League of Women Voters at
> the public hearing held June 20, 1977, relates to the proposed incineration of sludge from the York
"River STP. Even though the incinerators at the Boat Harbor STP which are to be used meet
applicable emission standards and will not directly cause the violation of ambient air quality stan-
dards, additional pollutant emissions in an AQMA for particulates must be considered unacceptable
if viable alternatives such as land disposal exist. HRSD should formulate a comprehensive sludge
management program for all of its treatment facilities on the Peninsula and continue to evaluate
land application as a disposal alternatiave, including its water quality impacts.
It is estimated that, at an average daily flow of 63.5 mgd, HRSD facilities on the peninsula will
V-l
-------
produce 593 tons per day, dry weight, of sludge for disposal. This could be converted into about 508
cubic yards of compost per day.
The estimated costs of composting 59.3 tons of sludge per day, based on Colacicco (1976), are $6 per
ton of dry sludge for capital costs and $27 per ton of dry sludge for operation and maintenance. Total
costs would be about $33 per ton of dry sludge. Approximately 20 acres of land would be required for
the composting operation.
Spreading of compost on parklands or woodlands is limited primarily by the nitrogen uptake rate;
nitrogen in the sludge can not be applied faster than it can be utilized by plants, or it will leach to the
ground water. Heavy metals must also be considered. There is little information available regarding
the characteristics of HRSD sludge. However, assuming typical characteristics for domestic
wastewater sludges, and assuming that parklands have a relatively modest nitrogen uptake rate of
100 Ib/ac/y, over 8,000 acres of land will be necessary for the safe application of compost over the
next twenty years.
Inquiries made by EPA to other agencies in the peninsula area indicated that there may be some
interest in using compost. However, there have been no firm commitments, and the "market" for
compost must be considered unknown.
Since capital costs for constructing a composting site are low, and at least a potential market ex-
ists, it appears worthwhile to establish a pilot composting program on the York-James Peninsula. A
test project is currently underway by HRSD at the site of the new Atlantic STP in Virginia Beach. It
is possible that, with compost available, various agencies on the peninsula will be encouraged to ex-
periment with the use of compost on their lands. Should this prove successful, the net result would be
a more beneficial means of sludge disposal than the present incineration and landfill process.
It is therefore recommended that a pilot composting study be included as part of the Step II plan-
ning process. This study should include the following elements:
(1) Sludge Testing
Sludge from the existing James River plant, and the York River WWTP when it goes on-line,
should be tested for nutrients, metals and pesticides. The results of these tests will help determine
safe application rates.
(2) Pilot Composting Operation
A small composting operation should be established to help determine the design of a full-scale
facility. The compost produced should be used for test plots and preliminary marketing studies.
(3) Test Plots
Test plots would be established on parklands and woodlands with a range of application rates.
These plots would not only serve a safety purpose, by detecting buildups of heavy metals or nitrogen,
but should also be used as demonstration plots for the marketing effort.
(4) Marketing Program
The studies mentioned above should demonstrate the feasibility, safety and direct costs of the
composting alternataive. However, the success of a land application program hinges on the
willingness of the federal and state agencies on the peninsula to utilize the compost on the lands un-
der their control.
A marketing and costing program should address the following items.:
Benefits of sludge application and the willingness of users to obtain these benefits.
Cost of producing sludge, and a fair market price.
Maximum demand for sludge.
'Optimal distribution strategy.
« Public relations.
V-2
-------
Issue: Treatment capacity
HRSD has applied to EPA for PL 92-500 funding to construct a wastewater treatment facility
designed for the following wastewater flows:
Average daily flow - annual = 15.00 mgd
Average daily flow - maximum
30 day = 18.75 mgd
Average daily flow - maximum
7 day = 22.50 mgd
Peak daily rate = 37.50 mgd
HRSD's request was based upon existing and future needs within the proposed service area and in
the interconnect system.
It must be recognized that the different units of a wastewater treatment plant are sensitive to
different design flows. For example, a pumping station would be sized primarily to handle the peak
wastewater flow, while sludge digesters (which are sensitive mostly to long-term solids loading) are
usually sized for the average annual daily flow. Thus a "15 mgd plant" is actually a nominal rating
and implies a variety of design flows for different periods of time.
After a considerable amount of discussion with EPA regarding population projections, per capita
water consumption, and calculation of infiltration/inflow, GFCCpresented HRSD's rationale for flow
projections to EPA in a letter dated February 1, 1977. A copy of this letter is Contained in the cor-
respondence section of the DEIS.
HRSD's projections are based on the maximum 30-day wastewater flow. This is because the HRSD
service area is subject to a seasonally high groundwater table, which causes increased infiltration
into the system for part of the year. As the plants' discharge permits are all written with a 30-day dis-
charge limitation, HRSD considers the maximum 30-day wastewater flow to be the principal design
flow for a treatment plant.
EPA has questioned these proposed flow projections on two points: (1) the allowance for in-
filtration/inflow; and (2) increases in per capita flows.
In addition, the York Chapter of the Chesapeake Bay Foundation in their letter of July 25, 1977,
(Appendix E) as well as at the public hearing on June 20,1977, raised the issue of excessive infiltra-
tion and inflow in the HRSD system.
GFCC calculated infiltration/inflow on the basis of observed wastewater flows less residential and
non-residential flows. While this is an acceptable method for calculating system-wide I/I, it assumes
that it is not cost-effective to rehabilitate the sewerage system to remove the extraneous flows. The
Virginia State Water Control Board has certified to EPA that the Boat Harbor, James River, and
Williamsburg systems (i.e., the existing sewerage system of the Peninsula) are not subject to ex-
cessive I/I, which means that it is cheaper to treat the extraneous flows at the treatment plants than
to repair the leaks in the sewerage system. McGeorge (1977, Personal communication) estimated that
I/I correction in the Boat Harbor system would cost $19,760,000 or about $3.80 per gpd removed.
Anthony Koller, EPA, in a memorandum on May 31,1977, (Appendix C) on the other hand, estimated
rehabilitation costs at only $3,300,000, or $0.63 per gpd, not including the costs of an evaluation sur-
vey. Such a survey would cost an additional $1,660,000 to $3,700,000 or $0.71 per gpd. By comparison,
the cost of wastewater treatment at the proposed York River plant will be about $1.80 per gpd, but
only about 21 percent, or $0.38/gpd of these costs are actually attributable to the design 30-day
average flow. The remaining costs are a function of other design parameters such as BOD and
suspended solids. Therefore, EPA concluded that, despite the inconsistencies in the I/I cost-effective
analysis, I/I was non-excessive. It must be pointed out, however, that the specified allowances for I/I
must be maintained in the system and cannot, at a later date, be reallocated to residential or commer-
cial wastewater flows, without proof that I/I flows have, in fact, been reduced through rehabilitation
or are lower than originally anticipated.
Flow equalization has been suggested as a means of reducing the amount of treatment plant
capacity necessary for treating infiltration/inflow. However, the infiltration/inflow component of
V-3
-------
flow used by GFCC is the maximum 30-day I/I, and is primarily long-term infiltration caused by an
elevated ground water table, rather than short-term inflow caused by storms. Thus, extensive
amounts of storage would be required to reduce this peak 30-day flow significantly.
Regarding the second issue, per capita flows, EPA (1977) proposed that allowances for future in-
crease of per capita wastewater flows with time will not be approved unless a complete justification
for such increases is provided and conservation factors tending to decrease per capita flows have been
thoroughly analyzed in the facility plan. The GFCC (1977) flow projections propose that per capita
flows on the Peninsula will increase from 62.7 gcd in 1980 to 75.1 gcd in 1995. Both the City of New-
port News and the PPDC have indicated that sufficient water is available to support total residential
and non-residential consumption rates of 165 gcd in 1995. However, the immediate availability of
water is not sufficient reason to justify increasing per capita use.
It is EPA's opinion that, although HRSD has been unsuccessful in attempts to reduce increasing
domestic consumption, there is no justification for further increased beyond projected levels for 1980.
Therefore, capacity will be provided for only these levels of domestic consumption in the future. In
fact, at some future date, actual reductions in domestic consumption may become necessary.
Maintenance of per capita residential consumption at 62.7 gcd would result in projected 1995 Penin-
sula wastewater flows as shown in Table V-l.

(5) Existing treatment plant design flows: Boat Harbor - 25.0 mgd; James River - 15.0 mgd; Williamsburg - 9.6 mgd. Total
equals 49.6 mgd.
EPA reviewed the availability of the existing treatment plant capacity of the interconnected
system based upon data presented by GFCC (1974; 1977, Personal Communication) and HRSD (1977,
Personal Communication). EPA concluded that the existing system capacity in 1977 was 49.6 mgd,
compared to a projected 1980 flow of 51.5 mgd. Thus, it appears that at least some increment of
capacity will be required. HRSD (1977, Personal Communication) proposed that approximately 3.5
and 3 mgd can be transferred from the York River service area to the Boat Harbor and James River
plants respectively. This leaves about 3.7 mgd of the 1980 flow from the York River service area
which either must be treated at a new facility, or pumped to another treatment plant via a new inter-
connection.
It appears that, by 1995, the peninsula will require a total wastewater treatment capacity of 63.47
mgd, or an increase of 13.9 mgd over the present capacity. The 1995 flows for the York River service
area will be 14.40 mgd of which only 6.5 mgd could be transferred to other interconnected plants. In
this respect, a 15 mgd (30 day) initial capacity appears to be proper for initial construction of the York
River plant. Therefore, it is included that the design flows for the York River wastewater treatment
plant shall be as follows:
Average daily flow - annual* = 13.7 mgd
Average daily flow - maximum
30 day = 15.0 mgd
Average daily flow - maximum
7 day** =20.6 mgd
Peak daily flow*** = 34.3 mgd
* Assumes I/I at 1/2 of the 30 day maximum
**1.5 times annual average
***2.5 times annual average
New population projections for the Peninsula have been developed by the Tayloe-Murphy Institute
for the State of Virginia.
The York Chapter of the Chesapeake Bay Foundation, in the inquiries regarding regionalization
mentioned above, questioned the effects of these new figures in computing treatment capacity.
Applying these new population figures to the methodology previously used by EPA to predict
wastewater flows, the following flow projections were determined:

Total Wastewater Flow 59.18 mgd 13.07 mgd
Subtracting the existing HRSD system capacity of 49.6 mgd, it is seen that, under these projec-
tions, only 9.6 mgd of additional capacity is needed in the entire system by 1995, although 13.07 mgd
will be needed in the York River Service Area. For this reason a 13 or 14 mgd plant size for York River
would more closely fit service area projections. The net effect of this "oversize" would simply extend
the design life of the facilities by an increment within the design life recommended by EPA
regulations.
For additional discussion of component alternatives, refer to page V-l of the Draft EIS, Appendix
A (not included).
B. SYSTEM ALTERNATIVES
The following substantive issues related to system alternatives were raised through comments or new
developments since publication of the Draft EIS.
Issue: Staged construction versus regionalization
A discussion in the Draft EIS beginning on page V-21 concluded that regionalization at the James
River STP was more cost-effective than construction of the new York River STP. New cost figures
which include data specific to the physical constraints of this project, however, generate a different
conclusion. Since the alternative of regionalization generated support from individuals opposed to the
proposed York River STP, a discussion of the new computations which change the conclusion of the
Draft EIS is given below. This discussion originally took the form of errata sheets distributed at the
public hearing on June 20, 1977.
The applicant proposed that 20 mgd additional treatment capacity (15 mgd at York and a 5 mgd ex-
pansion at James) will be needed for the Peninsula by 1996. Cost of expanding to 20 mgd in other in-
crements of capacity, which were not evaluated by the applicant, are summarized below in Table V-2.
The costs presented are based on general guidelines and may vary for specific facilities. Alternatiaves
III and IV are both more expensive than the proposed alternative and would be justified only if flow
projections are highly uncertain.
Alternative II, which is the cost of expanding a generalized facility in a single increment of 20 mgd,
would save 16 percent over the expansion as presently proposed in Alternative I. However, the
analysis of this generalized alternative must be modified to include the data from Table V-3 which is
specific to the physical constraints of this particular project. In order to accomplish this modification,
the applicant's cost estimate for a 15 mgd plant was scaled according to the following method.

Tables 1-9 and 1-10, from the Draft EIS, which present the applicant's capital and O&M costs for the
York River 15 mgd plant were used. The costs of the effluent pumping station and force main, which
are not necessary if Alternative II is selected, were deducted from these capital and O&M costs. The
remaining costs are $16,951,000 capital and 525,000/yr O&M. The generalized estimates of plant cost
based on Table V-2 are:
20 mgd 15 mgd 5 mgd
Capital $5,968,000 $5,039,000 $1,252,000
O&M 605,000/yr 520,000/yr 275,000/yr
Thus, the applicant's capital cost estimate for a 15 mgd facility are 3.36 times the estimates of Table
V-2 ($16,951,000/$5,039,000 = 3.36). The O&M cost estimate made by the applicant is 1.01 times
greater than estimated in Table V-2 ($525,000/$520,000 = 1.01). These scale factors are then applied to
the generalized plant costs listed above to provide normalized figures for comparison with Table V-3.
Difference

Capital $20,076,000 $16,951,000 $4,212,000 $21,163,000 $1,087,000
O&M 611,000/yr 525,000/yr 278,000/yr 803,000/yr 192,000/yr
The savings of $1,087,000 in capital costs and $192,000/yr in O&M costs can now be added to the
costs of Table V-3.
Capital O&M
Additional Costs Incurred (Table V-2) -$11,330,000 -$ 70,000/yr
Cost Savings (Table V-2) 8,250,000 99,000/yr
Economy of Scale Savings (above) 1,087,000 192,000/yr
Total Savings -$ 1,993,000* $221,000/yr
(savings)
Using a present worth factor of 11.13, the net present worth of the total savings is $467,000.00 less
than 2 percent of the total project of the total project costs of. Since estimates of costs are rarely con-
sidered more accurate than ±10 percent, it appears that both a 20 mgd plant and a 15 mgd plant with
a 5 mgd future expansion are equally cost-effective.
The additional cost of increasing capacity of the James River STP by 15 mgd rather than building a
15 gd plant at York is estimated to be $2,730,000. Thus, this alternative does not appear to be cost
effective.
Constructing a 20 mgd facility at the James River site which would incorporate the 15 mgd propos-
ed capacity for the York River STP and a proposed 5 mgd expansion of the James River facility would
result in a savings of $467,000 or less than 2 percent of the total project costs. Since cost estimates are
rarely considered more accurate than ±10%, it appears that a 20 mgd expansion and a 15 mgd plant
with a 5 mgd future expansion are equally cost-effective.
Issue: Alternative STP sites
Numerous comments on the Draft EIS questioned the lack of an explicit evaluation of alternative
STP sites. Areas north of Fort Monroe, in Hampton, have been identified as potentially surplus by the
U.S. Army and were suggested as potential alternative sites in comments on the Draft EIS. This issue
was raised by the York Chapter of the Chesapeake Bay Foundation in letters dated June 25 and July
25, 1977 (Appendix E), and at the public hearing on June 20, 1977. Letters regarding this issue were
also received from the U.S. Department of Commerce (August 16, 1977, Appendix E), Mr. Fred
Schaumburg (July 21, 1977) and Mr. Prentis Smiley (July 15, 1977, Appendix E).
V-8
-------
Discharge points upriver of the proposed location at the VEPCO outfall were not considered since
the severity of impacts would increase upstream. Commercial shell-fishing, not viable below the near-
by bridge at Gloucester Point, is practiced north of this point. In addition, flows in the York River
would be less upriver and tidal mixing would decrease, also tending to increase impacts.
An expansion on the James River is discussed elsewhere in Section V-B.
An outfall on the Chesapeake Bay, such as would be used with the suggested Fort Monroe site, was
examined by Hydroscience, Inc. in their analysis for the facility plan. The Hydroscience assessment
concluded that a bay outfall would have slightly less impact than the applicant's proposed discharge,
but this difference was described as below the level of reliable measurement.
Construction of a new wastewater treatment plant on the bay at Fort Monroe, instead of at the
York River site, would necessitate transferring the sewage flows from the York River service area
througlrthe City of Hampton. This would be possible using force mains and interceptors. However,
using the costs developed .in evaluating the interconnect system, it is estimated that this construction
would cost approximately $13 million in additional expenditures.
Also, the structures and operations of a wastewater treatment plant may not be compatible with
the historic nature of the nearby fort. There is also a problem with site acquisition, as the property
must now be offered to all federal agencies, including the Interior Department (which may also be in-
terested in acquiring the property), before it can be offered to a unit of local government. These
procedures would almost certainly result in a lengthy delay in plant construction, and there is no
guarantee that the property would ultimately be available.
Therefore, the alternataive of a site at Fort Monroe must be rejected due to increased cost and
questionable availability.
For additional discussion of system alternatives, refer to page V-18 of the Draft EIS, Appendix A
(not included).

VI. RECOMMENDATIONS
EPA has developed the following recommendations based on the Draft EIS, comments received, and ad-
ditional information analyzed since publication of the DEIS. The following list is a summary of these
conclusions; a complete discussion of the rationale for each conclusion is provided in this EIS or the Draft
EIS (Appendix A).
1. HRSD has applied to EPA for PL 92-500 funding to construct a wastewater treatment facility
designed for the following wastewater flows:
Average daily flow - annual = 15.00 mgd
Average daily flow - maximum
30 day = 18.75 mgd
Average daily flow - maximum
7 day = 22.50 mgd
Peak daily rate = 37.50 mgd
EPA has questioned proposed flow projections on two points: (a) the allowance for in-
filtration/inflow; and (b) increases in per-capita flows.
(a) EPA has concluded that I/I was non-excessive. It must be pointed out, however, that the
specified allowances for I/I must be maintained in the system and cannot, at a later date, be
reallocated to residential or commercial wastewater flows, without proof that I/I flows have, in fact,
been reduced through rehabilitation or are lower than originally anticipated.
(b) Regarding per capita flows, GFCC (1977) projections propose that per capita flows on the Penin-
sula will increase from 62.7 gcd in 1980 to 75.1 gcd in 1995. EPA concludes that this increase is not
justified and capacity will be provided to meet a projected consumption of 62.7 gcd in 1995.
After reviewing the availability of the existing treatment plant capacity of the interconnected
system, it was concluded that the design flows for the York River wastewater treatment plant shall
be as follows:
Average daily flow - annual* = 13.7 mgd
Average daily flow - maximum
30 day = 15.0 mgd
Average daily flow - maximum
7 day** =20.6 mgd
Peak daily flow*** = 34.3 mgd
*Assumes I/I at 1/2 of the 30 day maximum
*1.5 times annual average
***2.5 times annual average
New population projections for the Peninsula have been developed by Tayloe-Murphy. Applying
these new population figures to the methodology previously used by EPA to predict wastewater
flows, leads to the conclusion service area projections for York River. The net effect of this "oversize"
would simply extend the design life of the facilities by an increment within the design life
recommended by EPA regulations.
2. EPA has concluded that the applicant has had difficulty developing adequate pretreatment re-
quirements for Anheuser-Busch brewery discharges, with the result being operational difficulties at
the Williamsburg facility. This problem is under study and will be resolved by HRSD as part of a
Step I Construction Grant application for modifications to the Williamsburg STP.
3. The applicant's proposal to rely upon incineration as a sludge volume-reduction method in an
AQMA for particulates requires further evaluation. Even though the incinerators meet applicable
emission standards and will not directly cause the violation of ambient air quality standards, ad-
ditional pollutant emissions in an AQMA must be considered unacceptable if viable alternatives such
as composting and land disposal exist. Thus, EPA views land application of sludge as the preferred
method and incineration should be used only as a final alternative. In order to accomplish this end,
VI-1
**i
-------
EPA is recommending that a pilot composting study be included as part of the Step Two grant. The
study will include sludge testing, a pilot composting operation, test plots and a marketing-feasibility
study.
4. The principal, primary, long-term impact of the applicant's proposed project will be a substantial
increase in point-source pollutant loading of the lower York River. During normal operations at 15
mgd the proposed facility will discharge 3750 Ibs/day BOD, 2500 Ibs/day ammonia-nitrogen, 4380
Ibs/day total nitrogen, and 1000 Ibs/day total phosphorus into the estuary. These loadings will in-
crease the average concentrations of total phosphorus in the estuary by approximately 20% and total
nitrogen by approximately 10%. The Hydroscience model has predicted that the net effect of the
York River discharge will be minimal and will not preclude any beneficial use of the River. Further
the effect of the increased loadings must be balanced against both the detrimental effects of existing
and future failing septic tank systems on groundwater, surface waters and public health, and
against the severe economic effects of the no-action alternative.
5. Without extensive collectors, growth inducement cannot be tied to an increase in regional treat-
ment capacity such as the proposed York River WTP represents. However, if extensive collectors are
constructed, growth inducement may easily result. In light of preliminary indications of growth in-
ducement potential, further "201" planning efforts for collectors in Sanitary District No. 2 will fully
consider secondary land use effects of collectors. This process will assure that collectors are not over-
sized, and therefore do not promote induced growth.
HRWQA is currently preparing an Areawide Waste Management Plan which will address the water
quality impacts of growth and which jurisdictions served by HRSD should adhere to as strictly as
possible.
For these reasons, secondary impacts from growth related to the York STP are not considered to be
excessive.
6. A committment must be secured by HRSD from VEPCO for the joint use of the proposed outfall
as part of the Step Two Construction Grant process.

Section Page
I. DESCRIPTION OF THE APPLICANT'S PROPOSED ACTION
First line below "Type of Treatment" and "Design Capacity": delete 1-6
"Secondary" and "25.0"; add "Primary" and "22.0". *
Reverse information in items 16 and 17. 1-7
Second paragraph: delete last sentence, "Based. . . ." This deletion is made 1-8
due to a comment from HRSD in their "Attachment A" to their letter
of July 18, 1977 (Appendix E) indicating the data utilized could not be
relied on for the conclusion given; EPA concurred with this opinion.
Delete second paragraph; add: "The James River facility provides 1-13
secondary treatment, using the activated sludge process and chlorination
of wastewater entering the collection system. Treatment units at the
facility currently consist of screen chambers, grit collectors, pre-aeration
tanks, primary clarifiers, aeration tanks, secondary clarifiers, chlorine
contact tanks, waste activated sludge thickeners, anaerobic digesters,
and sludge drying lagoons. Effluent from the facility is discharged through
60 and 36-inch diameter outfalls which extend approximately 3,900 feet
into the James and Warwick Rivers at their confluence. In the past,
sludge from the James River plant has been land applied, but, according
to the HRSD, digested primary and waste activated sludge will be trans-
ported to the Boat Harbor plant for incineration; the reson for this
change is that the HRSD has not been able to find sufficient land for
sludge disposal. The annual operation and maintenance costs are pro-
jected to be approximately $644,000 in Fiscal Year 1976-77 (Table 1-5)."
This paragraph modifies and replaces the original in accordance with new
information supplied by HRSD in "Attachment A." This new informa-
tion relates to the number and size of outfalls and the current method of
sludge disposal at the James River STP.
Second paragraph, second line: delete "as a"; "This problem is currently 1-14
unresolved."
These changes are made due to data in HRSD "Attachment A" which
indicate that operational difficulties at the James River STP were not
conclusively due to toxic discharges to the facility.
Third paragraph, delete last line "Based upon an operational. . .", 23rd 1-14
line, add: "However, levels of BOD and SS from this lesser flow equaled
those originally anticipated from flows of 2.8 mgd (HRSD communication)."
First paragraph, delete last two sentences. Add "HRSD is negotiating 1-16
BOD and suspended solids limitations with the brewery, and has sub-
mitted a Step I grant application to solve this problem.
Third paragraph, last sentence: add "under construction and therefore" 1-16
between "were" and "not"; delete "due to unknown difficulties."
First paragraph; delete entire paragraph: Substitute "The Interconnect 1-17
System". In 1974, the SWCB directed that HRSD "prepare a plan for the
interconnection of all Peninsula treatment plants to provide protection
B-l

against pollution due to total or partial failure of anyone treatment unit".
The intent of the directive was to increase system reliability and maximize
existing capacity. The generally flat terrain of the Peninsula requires
that most wastewater flows be pumped to treatment facilities in the
service area of their origin. Because all flows must be pumped, intercon-
nection of the force main system was congruous with the existing system.
"The ability to transfer flows from treatment plant to treatment plant
makes it possible for the Commission to plan and manage the treatment
of its wastewaters in a highly cost-effective manner" (GFC&C, 1974).
The interconnect system allows HRSD some flexibility to define the serv-
ice area of its plants. The decisions are based on conditions and charac-
teristics of systems and pumping costs as well as development and growth
patterns in an area. A system model proposed by Gannett, Fleming,
Corddry and Carpenter will enable HRSD to more efficiently predict line
pressures resulting from projected flows and the effects of proposed
emergency or minor permanent service area changes.
First paragraph, first subsection: delete "Route 17 interceptor" add "York- 1-27
town/York County Interceptor force main. . .".
First paragraph, second subsection, sixth line: delete "Route 17 inter- 1-27
ceptor" add "Yorktown/York County Interceptor force main. . .".
First paragraph, third subsection, second and sixth lines: delete "Route 17 1-27
interceptor" add "Yorktown/York County Interceptor force main. . .".
II. ENVIRONMENTAL SETTING
First paragraph, tenth line: change "10" to "11". 11-19
Directly above "Flood" and "Ebb": replace "York River" with "Back Creek". 11-24
Legend, following "Shellfish Closure Zones": add "in the vicinity of the 11-31
York River STP".
Delete last paragraph 11-34
Delete first paragraph 11-35
These deletions are made due to their material being inappropriately
located. This material is repeated on page IV-34 of the Draft EIS.
Delete third paragraph; add "The blue crab (Callinectes sapidus) is the 11-40
only genus of crab commercially harvested in the York River. Harvesting
activity is restricted by the Coast Guard to areas outside of the shipping
channels (Van Engle, 1976). Because of their mobility, and because themeat
is not eaten raw, shellfish closure regulations do not apply to crabs
(HRWQA, 1976). In the York River system (including Back River, Poquoson
River and Mobjack Bay), the approximately 300 commercial hard crab
fishermen begin working near the bay in March or May and follow the
crabs upstream to shallow waters in the tributaries by June or July
(Horrell, 1976). Approximately 50 individuals commercially harvest soft
crabs from the York River (Horrell, 1976). In the lower York River,
from the U.S. Naval Weapons Station to the mouth, approximately
4,400 pounds of soft crabs and 1,200,000 pounds of hard crabs were har-
vested in 1976, valued at $3,200 and $260,000, respectively (Gordon, 1977).
Although far fewer total pounds of soft crabs are harvested, these figures
show their dollar value per pound to be more than three times that of

hard crabs. No crab "pots" are currently being set in the vicinity of the
VEPCO outfall, and "peeler" or softcrab fishing is primarily restricted
to that portion of the York River upstream from the Route 17 bridge
(Horrell, 1976)."
This change incorporates information provided by the U.S. Dept. of Com-
merce in their letter of August 16,1977 (Appendix E).

These mitigating measures are deleted since they are not being pursued
as a direct attempt to ameliorate an impact and are therefore not technic-
ally "mitigating measures". This change responds to comments from the
U.S. Department of Commerce in a letter dated August 16, 1977
(Appendix E).
Second paragraph, add: "These loadings are in addition to those from IV-8

This paragraph is changed to reflect corrections supplied by HRSD in
"Attachment A."
First paragraph, first line, delete "$1,244,000" add "$980,052."
Second paragraph next to last sentence: change to read "Instead any

place "22.00" with "15.50".
Fifth paragraph, following the second sentence: delete remainder of text.
Add "Sewage treatment is a permitted use in this District."
Delete first paragraph.
This section is changed due to an incorrect description of the York County
Zoning Ordinance. Uses permitted in B-l include sewage treatment;
uses in B-l are included M-l; uses in M-l are permitted in M-2. There-
fore, M-2 allows sewage treatment as a conforming use.

In reply to your memo dated April 28, 1977, the Virginia State Water
Control Board certified to EPA on April 22, 1976 that the Boat Harbor
System was subject to non-excessive I/I. A copy of their certification
and their determination is attached.
The following is an estimate of possible costs for an I/I Evaluation sur-
vey and possible costs for corrective action:
1. Estimated costs for I/I Evaluation Survey
High = $2.U5/ft x 285.89 miles x 5280 ft/mile = $3,698,273
Low= $1.10/ft. x 285.89 miles x 5280 ft/mile = $1,660,UH9

c. Grouting of connections
Estimate 5 joints per MH Reach
Material = 20 x 5 x $UO.OO = $1*,000.00 U,000.00
Equipment Rental & Setup = 20 x $150.00 = $3.000.00
TOTAL PER MILE - $13,500.00
TOTAL COST OF CORRECTIVE ACTION

and manholes to correct infiltation. It does not represent any correc-
tive action to reduce inflow, such as cross-connection between sanitary
and storm sewers, elimination of roof leaders, etc. These costs would
be added on.
The cost figures used were from the 197^ Needs Survey Procedural Bulletin
and do not reflect higher costs due to inflation.

STATEMENT FOR PRESENTATION AT THE PUBLIC HEARING ON THE DRAFT ENVIRONMENTAL
IMPACT STATEMENT FOR THE PROPOSED YORK RIVER WASTEWATER TREATMENT FACILITY
CONDUCTED BY THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY, REGION III
MONDAY, JUNE 20, 1977
TABB HIGH SCHOOL, YORK COUNTY, VIRGINIA
The Chesapeake Bay Foundation, York Chapter has been involved in
this project for a long time, and is pleased that the draft EIS addresses
many of the concerns we expressed in our presentation at the hearing here
two years ago. In general, we consider the draft EIS a well prepared
document of appropriate scope and treatment of the subject, and we find
ourselves in agreement with the thrust of its Preliminary Conclusions
(page VT 1,2), though with some significant exceptions which are described
later. The draft EIS describes the substantial adverse environmental im-
pacts of the presently projected York River STP and points out that
there are desirable alternatives with less adverse impact, which have not
yet been adequately studied or considered. For the most part, the EIS
is cautiously worded with respect to its findings. Presumably, the bur-
den is on the applicant to substantiate that the York River STP is the
best solution.
Our immediate conclusion from the draft EIS itself (without taking
into account the questions and points we make below) is that in view of
the questions the EIS raises with regard to infiltration/inflow, per capita
flow projections, capabilities of the interconnect systems, over-capacity
at 15 mgd, alternatives to the York River site, and others, the EPA cannot,
Ude. g-nvitonmcntaC Untcgiity Of 1/h Cfuia foak
-------
in justice to its mission and the objectives of PL 92-500, approve the 15
mgd York River STP until and unless all of these questions are resolved
to show that it is the optimum solution, As we try to make clear below,
it is indeed not the optimum solution.
The relatively short time available between the receipt of the draft
EIS on Friday, May 27th and the hearing on June 20th has made it very
difficult to complete the work necessary for thorough review of the document
and preparation of a statement for the hearing. As stated in the last
paragraph of page xx, the matter under study is one of considerable com-
plexity. Time did not permit our dealing with such important topics as
Air Quality, Sludge Disposal, Land Application and Toxic Substances. How-
ever, these are discussed in our earlier letters and statements. The
following topics or issues are addressed in this statement:

draft EIS. Some are quite important and some relate to the listed topics.
Appendix B is
-------
A. POPULATION PROJECTIONS
(reference, Section III.C, p. 111-16)
We were rather surprised to see that EPA's population projections for
the York River STP Service Area (Table III-9) exceeded those of the PPDC
(Table III-7). We confidently expected PPDC to top all others. However,
GFCC's were highest.
The discussion recites how the EPA rejected the HRWQA projections and
proceeded to make its own projections for the York River STP Service Area.
From the information given, it is not possible to correlate the various
Service Area Projections and corresponding City/County Projections. In any
event, the population projections of interest are those for the cities,
the counties, and the Peninsula, not for the arbitrary York River Service
Area, and it is the sewered population that is the source of the residential
wastewater flow. We know that PPDC has been dissatisfied with the DSPCA
(now OPB) projections that came out in March, 1975. These were appreciably
lower than the projections used in the York River STP Preliminary Engineer-
Ing Report. A new edition of the OPB projections is about to be published.
It is interesting to compare the various projections for the Peninsula, all
in thousands:
1970 1975 1980 1995
GFCC, 1974 350.3 403.0 (525)
DSPCA, 1975 319.1 373.5 460.0
HRWQA, 1976 319.9 341.2 401.4
(OPB,1977) 319.1 332.8* 350.3 386.9
* 1974
The projections of future population are seen to be shrinking substantially
as the years go by. No doubt, PPDC will object to the latest projections
as being too low. We believe the PPDC, GFCC and EPA projections are inflated.
4
-------
We must point out again that population projections used for planning
sewers and roads are, to a very large degree, self-fulfilling prophecies
if they are acted on, and this should be recognized by all concerned.
An entirely different aspect of the population projections for the
York River Service Area, that deserves comment is that the portions of the
service area showing the greatest numerical growth, in Hampton and
Poquoson, lie in the 100 year flood plain, as can be seen by transfering
the flood plain boundary from Figure 11-15 to Figures 111-2,3,4 and 5.
(The more frequent flood plain boundaries will be related but show somewhat
smaller area.) While developers may choose to ignore the dangers of the
flood plain, it would appear that some fraction of prospective residents
will be aware and prudently avoid the area, or in the course of time a
disaster affecting the population numbers will occur. Was any notice taken
in the population projections? On the other side of the coin, it would
appear that local jurisdictions have some responsibility to avoid relatively
large populations on the flood plain. The reality of these concerns will
be apparent to those who remember the hurricane in the fall of 1933 and the
Ash Wednesday northeaster of April, 1962, when the water levels reached
nine and eight respectively above normal high water in Poquoson. Or will
Federal disaster assistance take care of everything?
-------
B. UNSATISFACTORY ON-SITE SEWAGE DISPOSAL SYSTEMS
(reference, page 1-18)
This list was prepared by the York County Health Department at the
request of the former County Administrator. The sole use for the list
was as justification for a Health Hazard declaration to improve the
probability of state and federal funding for the County's sewage col-
lection system. No other use has been made of the list, nor (even after
the declaration of a "most urgent health hazard") has there been any at-
tempt by any level of government to confirm the correctness of the list
or to have the problems corrected.
The 35 satisfactory and 60 unsatisfactory privies and the 24 cases
of no sanitary facilities listed are almost entirely in Lackey, a sub-
standard residential area immediately outside the main gate of the Naval
Weapons Station. There are no known plans for sewering this area. It is
inconceivable that the residents of this area could afford the several
thousand dollars per residence cost of sewage collection, even considering
75% federal funding. It is possible that at some future date a special
arrangement could be worked out with the Naval Weapons Station.
The other lists of some several hundred malfunctioning septic systems
are hard to evaluate. Spot checks have shown the list to be wrong. Ap-
proximately half the lists came from a drive around the area, and certain-
ly are questionable, A check of the locations of the malfunctions showed
that only about 20% would be included in the initial Sanitary District No. 2
collection systems. The CBF, YC urged York County to check the list, and
to seek alternative solutions to the identified problems. For example,
a CBF,YC member had a chronically malfunctioning septic tank during the
time interval involved (he was not on the list). He cured the problem by
adding on to the septic system at far less cost than connecting to a central
sewer and at zero cost to any governmental agency.
6
-------
The accuracy of the lists is known to be low. There are certainly
malfunctioning septic systems, but their nature and location are not
derivable from the lists. (We obtained the location information by
research of the original data.) The shame of the matter is that this list
was contrived for the special purpose of promoting the sewage collection
systems along Route 17. Its usefulness as a tool for seeking correction
of the malfunctions or for identifying the areas most needful of sewage
collection was, to the best of our knowledge, ignored completely by all
levels of government from local to federal (EPA).
-------
C. SOILS INFORMATION
The draft EIS presents a large volume of information on the natural
setting of the proposed STP. However, some glaring deficiencies are
obvious. The data on ground-water and the regional changes in ground-
water tables is out of date or it does not apply to the service area of
the STP. Similarly, the EIS does not address in a meaningful way the effects
on the ground-water of the diversion of the desseminated septic tank
effluents to surface discharge or the reduced infiltration created by
STP stimulated development. Without these data is is not possible to conclude
what effects the STP will have on the ground-water tables.
The report indicates that the soils in the proposed service area will
not support developments using septic tank drainfields. This is based in
part on the soils map (Figure II-3) which was gathered on a reconnaissance
survey. The map does not delineate major tracts of land that are suitable
for more intensive land uses and is not sufficiently detailed. Consequently
the soil data base is inadequate and cannot be used to support the position
that most of the area within the service area must be sewered.
The draft EIS contains a lengthy discussion of the soils on the STP
site (Figure II-4) and the geology of the area. Although the report points
out the inadequacy of the soils for various purposes, including roads, it
fails to indicate whether or not the site has adequate geology or soil con-
ditions to support large facilities, such as the large aeration and settling
tanks of a sewage treatment plant.

-------
D. HRSD PENINSULA INTERCONNECT SYSTEM
The draft EIS makes clear the significant discrepancies between gener-
alizations about the interconnect system on the Peninsula and its apparent
actual capabilities. For generalities, see first paragraph, page 1-17,
and also paragraph 7, SWCB letter of January 6, 1977, page 9 of section
VII: "Another reason for the increased capacity is that all of the facil-
ities in the Peninsula have to be interconnected so that all the wastes
from a facility can be transferred to the others in case of a malfunction."
(?). Actual diversion capabilities are discussed on pages 1-17,18; 1-29;
V-9,10; and VII-49 (HRSD letter of 4/4/77), but the situation appears
confused, and the nature of the limitations on diversion capability are
not made clear. It appears to us that indeed the system should be made
capable of diverting substantial flows both from and to any given STP,
and that it is worth a study to secure an optimum capability to minimize
individual STP capacity requirements, and for emergency use in event of process
or equipment breakdown at one of the STPs. This study should be a factor
in decisions on future STP capacities, including the present case.
-------
E. HRSD PENINSULA INFILTRATION/INFLOW
(reference, page 1-11)
The Boat Harbor 11.3 mgd maximum average 30-day I/I flow is 46% of
the maximum total flow for any month during this period (24.6mgd),
which appears to us to be excessive, even though I/I is certified to
be non-excessive by the SWCB. Examination of Table 2 of GFCC's 2/1/77
letter (VII-44) shows that the maximum 30-day I/I flow at 2.2 mgd was also
a relatively high proportion of the total flow at the Williamsburg STP-
Table 3 of the GFCC letter of 2/1/77 projects much lower (but still very
high) Boat Harbor I/I flows, but it is not made clear how the re-
ductions are to be achieved.
It is interesting to compare the projected total wastewater flows on
the Peninsula as calculated by GFCC in Table 3 of the reference letter
and those of Table 13 of the 1974 Preliminary Engineering Report (mgd).
Table 13(1974)

Table V-6
EIS
47.38
57.96
It is seen in the table that the GFCC projected flows are about
the same, achieved by using the maximum 30-day I/I flows, (Table 3)
Instead of average I/I, as the sewered population projections reduced
from those used in Table 13 (from 463,700 to 406,300 for 1995). The
gpcd increased with time in both cases, from 58 to 75 for Table 3, and
60 to 79 for Table 13. The non-residential component (shown in parentheses)
remains the same. The EIS projection, Table V-6, with average I/I and con-.
stant gpcd is shown for comparison.
10
-------
The actual average total flow for 1974 was 33.8 mgd and for 1975 was
39.8 mgd (a wet year). For 1976 it was 36.3 mgd. So far this year it
is 38.6 mgd. Inspection of,the monthly average flow at the Peninsula STPs,
together with the information presented in Table 2 of the GFCC 2/1/77
letter, clearly shows the great importance of the I/I characteristics of
a system. The contrast between the flows in November 1974 (27.5 mgd total)
and 4 months later in March, 1975 (48.8 mgd total, 21.3 mgd greater) is
impressive, as is the Boat Harbor STP component of the flow, which went
from 14.7 mgd to 31.3 mgd, 16.6 mgd higher.
Table 3 of the reference letter projects the Peninsula 1975 I/I flow
to be 10.7 mgd (30-day maximum I/I), about 26% of the total flow. STP
capacity to treat the I/I component represents a substantial investment,
and points out the importance of the cost study on rehabilitating the Boat
Harbor conveyance system. It appears to us that there is more than cost-
effectiveness involved in a decision on rehabilitation of the system. It
is not simply a matter of comparison of the costs with the cost of addition-
al treatment capacity at the York River or James River sites. The en-
vironmental and social impacts of the increased STP capacity and effluent
flow must also be considered. It appears to us that the value of rehabil-
itation is very much greater than the dollar cost of treatment capacity
for the I/I flow reduction.

F. HRSD PENINSULA. OPERATIONS
The draft EIS cites a number of instances of problems in the operations
of the James River STP (page 1-13) and the Williamsburg STP (page 1-15,16).
The third paragraph on page 1-16 cites thr EPA requirements for pre-
treatment regulations to be established by the public treatment authority,
and that HRSD has not formulated the required standards for Anheuser Busch.
A hearing on these problems was held before the SWCB on June 6, 1977 (being
continued from the previous December) to consider the permit violations at
the two plants, and the two matters were voted to be continued until
September. At the hearing, there was no discussion of the reasons for the
James River STP being out of compliance from December through April. It was
stated that the plant was back in compliance with the new 30 BOD/30 Sus-
pended Solids mg/1 requirement (replacing the former 20/20) in April and May,
and the matter was continued, dn the problems of the Williamsburg STP, HRSD
testified at length as described in the press reports, but it was not made
clear just how the "spill" or "pretreatment failure" at Jeffco occured,
whether it was human failure or process failure; structural failure or what
the cause of the failure was. No questions were asked about this. The
major part of the testimony related to problems in treating brewery waste,
with the very large fluctuation in flow now being considered a major dis-
turbing factor. It was reported that the plant was back in compliance the
last two weeks in May and the matter was continued. It should be noted
that there has been a continuing history of violation of permits and re-
duction of permit requirements going back at least to 1974. A summary per-
formance report in the SWBC's quarterly newsletter of September, 1974
illustrates the situation at that time.
The continuing problems at the Williamsburg STP makes one wonder about
the wisdom of HRSD's having contracted with Anheuser Busch to treat
2.8 mgd of brewery waste as an inducement for location of the brewery on
12
-------
the Peninsula. With the continuing problems since the start of operations,
the prospect of having to treat an additional 2.8 mgd when the brewery
decides to expand, is positively discouraging. Any expression that extra
capacity is needed because of the difficulties of treating the brewery
waste are inadmisable. Anheuser Busch must conform to pretreatment re-
quirements .
We are dismayed by HRSD's defense of chlorine as a disinfectant and
the questioning of chlorine's toxic effect on aquatic life, as reported in
the press in mid-May. This is a very serious matter for the waters around
the Peninsula. The occurance reinforces our impression the HRSD's interest
in environmental problems is strictly secondary.

G. ENVIRONMENTAL IMPACT
In Table IV-1, Summary of Environmental Impact of the York River STP,
the Impacting Action "Relief/Elimination of peptic tanks and samll/pro-
liferated sewage treatment plants/facilities" is rated as Primary, long
term; Beneficial, and Significant with respect to Surface Water Quality and
Public Health. No other unequivocal Significant rating appears in the
table. This impacting action is discussed under related headings (pages
IV-7, IV-14, IV-24, IV-29). The basis for the beneficial rating of this im-
pacting action (also cited at lessee degree on 3 other parameters) is
evidently the unsatisfactory on-site sewage disposal systems listed on page
1-18 (the Health Hazard declaration) and also the Back River paragraph
(page 290) and the last paragraph on page 321 (lower York River) of the
referenced SWCB Water Quality Inventory 305 (b) Report.
An interesting aspect not referred to in the EIS is quoted from the
paragraph on page 290: "... and receive some suspected over-flows from
local pump station interceptors. These interceptors are faulty at times
and release raw wastewater into New Market Creek". This is mentioned as
"minimal to moderate" in Table IV-1.
The health hazard matter has been the subject of extensive corres-
pondence with EPA, covered elsewhere. The point to be made here is that
the relation between the 15 mgd York River STP and this impacting action is
so slight as to be practically non-existent. This is because no beneficial
impacting action will exist until sewage collection from the malfunctioning
sites exist, and when it does exist, it will be to an interceptor capable
of conveying the wastewater to any of the HRSD STPs.> It is seen that it is
the collection system, not the STP, which has the key role in locations
where the on-site system cannot be made to function properly. It should
also be noted that the failing York County Sanitary District No.l STP at
14
-------
0.368 mgd does not relate to the York River STP nor to the York County
Interceptor. It will be connected to a Williamsburg STP force main. In the
meantime, it does contribute pollution to the upper York River.
We notice that the STP effluent loading of the lower York River is
rated as "minimal to moderate, adverse". The contrast is between this
rating applied to the daily discharge (at 15 mgd) of 1.9 tons each of
BOD and Suspended Solids. 0.5 tons of total phosphorus, 2.2 tons of total
nitrogen, and substantial coliform bacteria when the STP is operating as
designed (page 1-19), and the "significant beneficial" rating applied
to the elimination of the intermittent polluted wastewater overflows of
the on-site facilities enumerated on page 1-18, the pollutant loading of
which at most, amounts to a small fraction of a pound on a daily basis.
We consider that the adverse impact of the STP discharge must be rated
"significant", to put it mildly.
15
-------
H. SURFACE RUNOFF
The York River STP proposes to eliminate the "health hazard" problems
in the small eastward flowing tidal streams south of Seaford by eliminating
the seepage from septic tank drainfields. However, the growth in develop-
ment induced by the STP along and east of Route 17 will create highly
polluted stormwater runoffs. The organic and inorganic pollutants in first
flow runoff from streets, parking lots, service areas and other impervious
areas is commonly comparable to domestic waste levels and the release of this
water directly into natural streams in the area east of Route 17 will have a
deleterious effect on" the stream biota and water quality.
Furthermore, STP stimulated development will necessitate the channeli-
zation and dredging of the natural upland drainage-ways to accomodate the
additional storm runoff. This will result in greater flood flows and lower
non-storm stream flows. As a consequence, these streams and their plant
and animal life will be destroyed and the streams will become as unsightly,
polluted and devoid of life as Newmarket Creek above Mercury Boulevard in the
Hampton-Newport News area. One of the principle objectives of the proposed
STP, the improvement of stream water quality, will be negated by its con-
struction.
16
-------
I. BIOLOGY OF THE YORK RIVER ESTUARY
A serious reservation still remains with respect to the calibration
and verification of the Hydroscience model, as cited on page IV-25 (also
page VII-63). Although there may be some acceptance of the model's ability
to simulate dispersion and dilution of conservative substances (N and Po),
the effects of these nutrients on the phytoplankton community is still
open to question because it is unknown whether or not the growth of the
phytoplankton community is nutrient limited (Jordan ^t _al_, 1975). In
addition, a high value of chlorophyll a_ is assumed as an initial condition
in the model with a result that an inconsequential increase of 5 ug/1
in chorophyll a_ will occur.
In aquatic studies, interpretations of the meaning of chorophyll. a.
do vary with respect to the phytoplankton communities which serve as the
base of the autotrophic food webs for higher trophic levels. Although
chlorophyll a_ levels of 50 ug/1 are considered "bloom" conditions for green
(Chlorophyta) and blue-green (Cyanophyta) algae in fresh water environments,
some authorities consider levels of chlorophyll a_ greater than 20 ug/1 for
diatoms and dinoflagellates in the estuarine (saline) environment to be bloom
levels. In a two year study at the mouth of the York River (1972-1973),
five out of 44 measurements of chlorophyll a_ were in excess of 20 ug/1 and
these were made when noticeable phytoplankton blooms were observed (Zubkoff
and Warinner, 1977). In another study at the same location on diurnal
productivity measurements in 1974, during 8 intensive study periods, only
rarely were levels of chlorophyll a_ greater than 20 ug/1 (Haas, 1975, Ap-
pendix B).
These two studies, in addition to that cited in the EIS, indicate that
the existing chlorophyll a level used in the Hydroscience model should have
a lower initial condition for chlorophyll a_ - possibly at the highest level
17
-------
of 20 ug/1 or even more reasonably at 10 ug/1.
Thus, there is another weakness concerning the effectiveness of the
proposed model with realistically simulating non-conservative biological
parameters, as cited on page IV-25.

J. EFFLUENT DISINFECTION
This matter is extremely important for the waters around the Peninsula,
but its treatment (page V-4) in the draft EIS is about as perfunctory as
it has been in the HRSD and SWCB documents. The one reference is not even
included in the reference list. We have been seeking information on de-
chlorination in practice for some time without results. It seems to us
that if we in Tidewater Virginia are serious about our shellfish commerce,
we must pay far more attention to protecting it from toxic pollutants than
we have paid in the past, including the elimination of the use of chlorine.
As of now, we have no confidence in dechlorination by SC>2. This is just
another chemical that can be overdosed by careless operators. We consider
that it would do much more for clean water and the environment C and our
shellfishery) for EPA to provide funds for non-toxic disinfection of the
effluent at all the STPs operated by HRSD, than the funding contemplated
for additional capacity "to promote orderly growth" (page xi).

K. HAMPTON ROADS WATER QUALITY AGENCY
(REFERENCE, pages III-2, IV-12)
This Agency is composed of the Peninsula Planning District Commission,
the Southeastern Virginia Planning District Commission, and the Hampton
I
Roads Sanitation District Commission, and was formed in 1974 under Section
208 of PL 92-500 to develop wastewater management plans. The Peninsula is
the northern half of the critical area. The completion date was originally
in 1976, subsequently extended to June .1977, -and most recenjtly to April, 1978.
EPA has provided 2.6 million dollars for this effort, which by its nature
provides vital information pertinent to the subject of this draft EIS.
In view of the need for this information and the investment of the sub-
stantial sum in the 208 effort, it would appear that extraordinary efforts
should be made to have the resolution of the York River STP problem
benefit from the 208 effort. It would appear from the trend toward down-
ward revisions in population and wastewater flow projections, as well as
the actual Peninsula wastewater flows in the past 4% years, that the situation
is not so critical as to require decision before the data from the 208 study
can be made available.

L. ADDITIONAL ALTERNATIVE SITE
It has never been made clear why effort was not made to secure
sufficient acreage for a STP on a small portion of the Federal land in
Hampton, between Fort Monroe and Buckroe Beach. This site is nearby to
the areas in Hampton which are projected to transfer from the Boat Harbor
to the York River service area. It is a natural low point on the Peninsula,
topographically. Its outfall would be furthest downstream of any site on
the Peninsula. The value of Fort Monroe to the Army as an operational
site is obviously diminishing, and it would appear that the transfer of
a small portion sufficient for a regional STP would not be unreasonable.
About 15^30 acres would be required, Obviously, the historical value of
Fort Monroe itself is beyond estimation, but the area under discussion is
considerably removed from the old Fort. Although Hampton is a major
contributor of present and future wastewater flows, all HRSD treatment
plants are distant from its boundaries.

M. PL 92-500, SEWERS AND GROWTH
It has been said that we (CBF,YC)are against growth. This is not so.
We recognize that the population of this country and of this state is going
to continue to grow for decades to come, and likewise the population of
the Peninsula and the upper counties. We hope that the economic growth in
terms of constant dollars will continue. But we are concerned about growth,
because we are concerned about our natural environment, and we are aware
how much the environment deteriorated as a result of growth in the recent
past. We are concerned that our growth and development, particularly in
York County, take place at a reasonable rate and within the carrying capacity
of the land, soils, water, and air (not to mention our financial capacity)
so that we maintain the attractive qualities of our environment as we grow.
We believe that most agree with us. We consider it imperative that the
"carrying capacity" concept be a basic condition for all growth and develop-
ment. By this we mean that our free enterprise system progress must be
made consistent with the carrying capacity of both our natural environment
(land, water and air) and our social environment, at the same time we are
repairing our past environmental insults. Perhaps it is noteworthy that a
page or two past the two page spread in the 6/12/77 Newport News Daily Press,
which focussed on the controversy about the York River STP, the results of
a recent Harris poll were reported. The headline was "Americans wary of
growth". A message to our officials and planners perhaps?
It seems evident that the goal of our local officials is unreservedly
"get the federal 75% of the money for the STP so that growth will not be
held up". The environment and clean water are secondary matters. There is
no question about their wanting clean water and a healthy environment, but
they want to be told that the impact of increasing effluent flows, urban run-
off, air emissions and so forth are tolerable, and they willingly accept
studies or interpretations that support this, as they did in the completely
22
-------
useless "Environmental Assessment" appendix to the Preliminary Engineering
Report.
The obsession with growth appears to stem from the belief that not only
is continuing economic growth the most beneficial state of affairs for all
of uss but it is essential for the solution of our social problems. It
appears that this belief is almost universally accepted at all levels of
government. Some appear to believe that when they conflict, environmental
considerations must bow to those of growth. This is a narrow, short term
point of view. We believe the long term considerations must prevail, with
growth and a healthy environment for ourselves and our future generations.
With this universal belief in the desirability of growth, there is of
course competition between localities and regions to secure the location of
new industries, new federal installations, new state installations, new
residents in one's own locality, etc. At the same time we also have the
phenomenon of net migration of residents from the inner city to the suburbs,
within the same commuting area, and the deterioration of the inner city.
This is already happening on the Peninsula, especially in downtown Newport
Newsand Hampton.' Suburban sprawl at the expense of the inner city is taking
place here. And it appears to us, that in funding the Yorktown Interceptor
(EPA C-510-465) and the Sanitary District No. 2 Collection System (EPA C-
510-405), EPA is contributing to suburban sprawl. We objected as strenuously
as we could to what is now the Phase I, Sanitary District No. 2 Collection
System (EPA, Region III has a substantial file of our letters and exhibits
in support of our position), but EPA chose to support the project as applied
for. The Route 17 Interceptor Project went through before we had learned our
lessons about sewers. The York River STP is another growth promoting pro-
ject.
The first words of PL 92-500, the Federal Water Pollution Control Act
23
-------
Ammendments of 1972, in it Declaration of Goals and Policy are: "Sec.
101.(a). The objective of this Act is to restore and maintain the chemical,
physical, and biological integrity of the Nation's waters.", but this and
the listed national goals and policies are rather pushed aside by the Act's
funding provisions, and growth is catered to under the otherwise prudent
condition: "Sec. 204(5). ..that the size and capacity of such works relate
directly to the needs to be served by such works, including sufficient
reserve capacity." It appears that in practice, the concept of reserve in
the sense of "keeping back" for special needs is utterly lost, and in the
absence of controls on the rate of use of the reserve, it's "first come,
first served". It appears to us that despite the disclaimer (page III-ll,
first paragraph) emphasizing environmental laws and regulations and which
leaves open the question of whether EPA regulations on qualifications for
grants are adequate uiider the goals and policy of LP 92-500, EPA has
greater responsibility for action than the relatively ineffective (in terms
of results) method of being satisfied with local intentions or agreements.
The discussion on pages IV-38 and 44 seeks to differentiate between
"accommodated growth" and "induced growth", with accommodated growth de-
fined as previously projectd population increases. The discussion does not
make very clear what induced growth is. Presumably, it is growth beyond the
original population projections. It is noted in the discussion that "lower
York County and Poquoson have the highest potential for single-family res-
idential growth inducement" (page IV-42) and also that: "lower York County
also has a significant potential for multi-family growth inducement". The
last paragraph on page IV-42 arid the five paragraphs on page IV-43 recite
studies by EPA which show undesirable sewage-related effects in undeveloped
and developing areas. For all this discussion, an extremely important part
of the problem is not addressed. This is the problem of controlling the
24
-------
growth of a region so that it proceeds at a reasonable rate, within the
capabilities of the locality involved. Some reference is made to this
problem in Section III-B., but the experience in York County in achieving
growth control means and in implementing them has been poor in the extreme.
This is mentioned in the draft EIS (page III-ll), but progress on the County
Master Plan and on up-dating the zoning ordinances to conform with the Land
Use Plan adopted March 4, 1976, has been insignificant. It appears that
resolution during 1977 will be impossible.
In considering regional growth, a most important component is res-
idential growth. It is instructive to compare growth rates correspond-
ing to population projections for the country, the state and our region.
The table below shows the average annual rates, in percent, with the Virginia
data taken from the DSPCA projections of March, 1975.

The principal question that arises is whether the higher rates on the Pen-
insula involve environmental degradation. It seems to us that for growth
rates higher than the national or state average to be acceptable, environmen-
tal degradation must not be allowed to occur.
We consider that EPA must face up to its responsibilities, because
events have shown that local and state governments cannot be relied upon
to exercise the necessary responsibility for the environment.

N. CONCLUDING REMARKS
We find ourselves in general agreement with the Preliminary Conclu-
sions (page VI-1) with some exceptions. We believe the conclusions can,
from information in the draft EIS, be taken further, and that additional
preliminary conclusions can be drawn, as follows:
Paragraph 1. additional Since they relate directly to required treatment
capacity, HRSD should institute a program to promote water conser-
vation and arrange its fee structure accordingly. HRSD studies and
estimates relating to the rehabilitation of the Boat Harbor collection
system to reduce excessive I/I should be expedited and also independently
reviewed to insure that the estimated costs are not inflated.
Paragraph 2. additional HRSD should conduct studies to establish the
requirements for an optimum interconnect system to secure maximum
system reserve capacity. If modification of the interconnect mains
and pumping stations are required, these should be undertaken.
Paragraph 3. additional HRSD should conduct a study in connection with
those mentioned above to arrive at the most cost effective and en-
vironmentally sound means for providing for reasonably projected waste-
water flows on the Peninsula for the ten years beyond 1980, at the
James River and Fort Monroe sites.
Paragraph 6. We disagree with this conclusion. Local ordinances to
manage growth and protect environmentally sensitive areas are not
present and have little prospect. Future growth in urban areas will
increase pollution through storm run-off.
Paragraph 7. additional paragraph The need for, and acceptable siting
of the proposed 15 mgd York River STP has not been established.
Our principal conclusion is that the draft EIS brings out very clearly
that in view of the lack of essential information (on the interconnect system,
26
-------
on I/I, on water conservation to maintain present per capita flows), an
intelligent decision on the capacity and siting of an addition to the HRSD
Peninsula system cannot be made at this time. It is very important that
a good decision be made because the environmental impact of additional STP
effluent will be significantly adverse. We are within a relatively short
time of having important needed data as a result of the HRWQA 208 project
work. It is evident that the present Peninsula system capacity is sufficient
to handle wastewater flows until a decision can be made and a facility put
into operation.
We request that we be informed directly and promptly of any action by
EPA, Region III on the application for funding of Step II and Step III for
the HRSD York River STP project.

Environmental Impact Statement Section
Re: Draft Environmental Impact Statement,
York River Wastewater Treatment Facility,
York County, Virginia.
Dear Mr. Morris:
I am writing regarding the above referenced document pursuant to the
opportunity for comments per 40 CFR 6, April 14, 1975. My understanding
is that comments received by July 8, 1977 will be considered for inclusion
scheduled for completion in August, 1977.
One of my concerns is that neither myself, Planning District Commission
ers, nor local officials particularly in New Kent and Charles City Counties
have been involved in the York STP/EIS process. This is quite perplexing
given this correspondence exchanged during the past two years, the major
pieces of which I have attached to this letter for your information, as
well as to elaborate our concerns for the benefit of the recipients of this
letter who prepared the York STP/EIS. It was on inquiry at my initiative
that I received the information ( the EIS draft) and that a public hearing
had been scheduled. Unfortunately, such was scheduled for the same date
and hour as our own 208 Study meeting.
Assuming that we will be dealt with on this matter in the future, I
offer the following comments to the Draft EIS which are in addition to the
attached materials and which illuminate our continuing concerns:

1. Environmental Evaluation of the Applicant's Proposed Project
pages S-9 through S-14 is a focal point of concerns of Planning District
15. I am specifically concerned that the statement, "secondary impacts
of the applicant's proposal are generally minimal", does not agree
with the resource allocations which impact the water resources of
the York available to localities upstream and the anticipated induced
growth with its ramifications on future increases in water resources
demand on the Chickahominy River. Regarding the former, I am concerned
that the allocation of conservative substances to the York STP outfall
will preclude the allocation of such substances to upstream development.
In the second point, I am not convinced that the proposed York STP will
not provide excess wastewater treatment capacity beyond existing available
water resources in the Peninsula Planning District (PPD). Apparently
the EIS shares one part of this concern (see page S-15 and the statement
that "EPA has concluded that 15 mgd may provide extra capacity ...")
but ignores secondary impacts which we see as occurring outside the PPD
but rather quite resident within the Richmond Regional Planning District,
(RRPD). Simply stated, figures shown me and included in EIS indicate
that the proposed increase in capacity can only reach full utilization at
the expense of water resources residents in RRPD. While the impact
of this situation may be "minimal" in PPDC, it is more than "potentially
significant" to RRPD.
2. These comments apply also to the "Summary of Environmental Impacts
Resulting from the Proposed Construction and Operation of the York
River Sewage Treatment Plant" beginning with the parameters of
Surface Water Quality and including that of Water Supply. In both
cases the impact, its "Degree of Impact", and "Mitigating Measures"
all apply only to the PPDC and/or the York STP Service Area. While
the statements may be true in that regard, I am concerned and assessment
of impacts on these parameters in the RRPD and recommend consideration
thereof prior to arriving at a final decision by EPA.
3. Additionally, regarding the Parameters Impacted of Social and Economic
Factors (see pages S-14), while EPA's consultant views the degree of
impact as "minimal" given the Federal subsidies for 75% of eligible
costs, two comments occur to me. First, that over the life span of such
a facility, the "0 and M" costs will far exceed the federal investments,
which, in my judgment fall in a category beyond "minimal". Second , again
I do not see any consideration of the social and economic dislocations
resulting from allocation of RRPD's water resources to the PPD in the
RRPD.
4. Finally, the Parameter Impacted of Land Use (page S-14) begins to reflect
some of my concerns expressed both abo-ve and attached. I feel its
degree of impact to be significant, and would urge EPA to look at this
parameter, along with those above, as it relates also to RRPD.

Dear Mr. Morris:
The Department has asked for our review and comments on the subject
document: DEIS:EPA--York River Waste Water Treatment Facility, York
County, Virginia.
Our comments are as follows. All sewage treatment plants that dis-
charge into shellfish growing areas are required to meet structural
and physical plant design requirements. These design requirements
are outlined in the Technical Bulletin entitled "Protection of
Shellfish Waters" (EPA430/9-74-010) and the Technical Bulletin
entitled "Design Criteria for Mechnical , Electric, and Fluid System
and Component Reliability" (EPA-430-99-74-001). At the present time,
all discharges of sewage treatment plant effluents into shellfish
growing waters should be from plants of reliability class I.
The above guidelines are necessary because of the'public health
hazards resulting from the harvesting of edible molluscan shellfish
from waters subject to discharge of pollutents. Shellfish are known
to concentrate pollutents from the aquatic environment. The
quality of the shellfish is directly related to the quality of the
overlying waters. Several outbreaks of enteric diseases related to
consumption of shellfish that have grown in sewage contaminated waters
have been documented. Since shellfish are frequently eaten uncooked or
partially cooked, there habitat must be protected to preclude contam-
ination and the resulting health hazard.
The National Shellfish Sanitation Program which is administrated by the
Food & Drug Administration requires shellfish growing area closures
surrounding sewage treatment plant discharges. The York River waste
water treatment plant facility will discharge into an approved harvest
area of shellfish. A closure is necessary and should be of sufficient
size to protect the public health as described in the Manual of
Operations of the National Shellfish Sanitation Program.
-------
Mr. Alvin R. Morris

This proposed waste water treatment facility will have impact on
shellfish growing areas. The upgrading of this plant to include
advanced waste treatment would reduce the BOD and suspended solids,
This changing concept would reduce the effect of this plant's
affluent on the shellfish growing area. A reduction of closure
size may, in fact, be possible due to a heightened disinfection
capability due to the lowering of the organic load of the effluent.
If you have any questions, you may contact Mr. Robert H. Brands at
301/962-4052.

Dear Mr. Morris:
Thank you for the letter of May 18, 1977, requesting our
views and comments on the draft environmental statement for
the York River Wastewater Treatment Facility, York County,
Virginia. Except for the comments and suggestions listed
below, the document adequately considers those areas within
our jurisdiction and expertise.
Page 1-23, paragraph 2 -- The frequency and magnitude of
storm-generated tidal flooding of greater than 100-year
frequency should be considered. Such data would be use-
ful to evaluate any adverse effects of potential flooding
of the proposed site that may exceed the 100-year flood
protection.
Page 11-79, paragraph 3 Inland, wetlands not dependent
upon or associated with tidal action should be included in
this section if they are present. Such wetlands are
generally more subject to development as they are less
protected by state and Federal laws.
Page 11-81, Endangered Species -- The fact that no endangered
animal species are reported in the study area does not
necessarily mean they do not exist there. If there are
any plans to determine if the primary study area as well as
the service area contain endangered species these plans
should be described in this section.
-------
Was a specific reconnaissance made to determine the presence
or absence of endangered plants in the primary study area?
If so, this should be indicated in this section.
Page 11-33, Terrestrial Fauna The reference to wooded
tracts which are large enough to meet territorial requirements
should be amplified by inclusion of wildlife population
density data which is available from the Virginia Commission
of Game and Inland Fisheries.
Page IV-1 If land application of sludge is to be considered
more fully as suggested by the Environmental Protection Agency,
resultant impacts on ground water should be fully assessed.
The consideration of the use of outfalls in the river or bay
for effluent disposal (p. V-4 through V-6) should include
as assessment of impacts related to the export of ground
water over and above those resulting from elimination of the
recharge from septic tanks.
Pages IV-2-6, Table IV-1 The mitigating measures cited in
Table IV-1 should be considered carefully. In reference to
"Recreation," the phrase "Preservation of the sewage treat-
ment plant site" is inaccurate since preservation is an
alternative rather than a mitigation measure. If the pro-
ject is designed to provide access to waterfront or a tot
lot or other recreation facility, then such a facility
would be a mitigating measure in regard to recreation.
The provision of open area around the treatment plant is a
minor mitigating measure at that site in regard to open
space. However, the "Preservation of critical open space
and environmentally sensitive areas" is not a program respon-
sibility assumed by this project nor by those who are managing
the project. Further, the phrase "Preservation of critical
open space . . . ." is to general to be considered a specific
mitigating measure.
The Summary, Item 3, asserts that "Many of these secondary
impacts will be mitigated as a result of local ordinances to
manage growth and protect environmentally sensitive areas,
" Again, this project cannot assure managed growth.
The sponsoring agency does not have authority to control
any of the specific areas listed. Further, the mere "...
presence of substantial areas of land which cannot be
developed . . ."is not a mitigating measure. This para-
graph should be rewritten.
-------
Mitigation measures should properly be defined as those
specific items and actions to be undertaken as a part of
the proposed project, and by the project sponsor, rather
than a general list of community goals.
The term "secondary development" is used several time in
Chapter IV, especially in regard to recreation and aesthetics.
It would seem that a more accurate term would be "induced
development" as used in regard to Land Use in Table IV-1.
Page IV-7, Section A.I, Section IV.A.I, Surface Water Quality --
In the discussion of erosion and sedimentation, the statement
is made that strict enforcement of state and local erosion
and sediment control ordinances will minimize undesirable
affects. We believe that erosion and sedimentation are
major habitat disruption elements when considering develop-
ment of an area. As such our interpretation of the above
statement leads us to believe that there will be strict
observation of such laws. We believe that an evaluation of
past local and state enforcement efforts should be included
to support the positive position taken in this section with
regard to erosion control.
Page IV-26, Biology The section dealing with secondary
environmental impacts upon vegetation and wildlife should be
expanded and quantified. Additionally, secondary environmental
impacts regarding endangered species, if any, in the study
area should also be addressed.
Page xV-UV -- Irreversible and Irretrievable Commitment of
Resources Which Would Be Involved In the Applicants Proposed
Project Should It Be Implemented. The loss of public fish
and wildlife resources through habitat destruction should be
thoroughly addressed in this section.
We hope these comments and suggestions will be of assistance
to you.

EIS PREPARATION SECTION - YORK RIVER DRAFT EIS
Environmental Impact Branch
United States Environmental Protection Agency
Region III
Curtis Building 6th and Walnut Streets
Philadelphia, PA 19106
Dear Sir:
I have followed, with great interest and concern, the irrelevant
and irrational statements presented by those in opposition to the
York River Wastewater Treatment Facility at your hearing on June 20, 1977
in Tabb High School.
Our economy minded Board of Supervisors have spent many hours
cutting $420,000 out of the County Administrator's recommended budget,
but have lost all sense of fiscal responsibility by suggesting that the
additional 15 MGD sewage treatment capacity needed for this area be
built at the James River Facility at an added cost of $3,050,000.00.
Speaking as a York County resident and taxpayer and as Federal taxpayer,
this additional cost cannot be justified.
As a potential HRSD customer (the York County local collection
system is under construction now adjacent to my place of business) the
additional costs cannot be justified.
My good friends from the Chesapeake Bay Foundation York Chapter
say that an intelligent decision cannot be made until more study is done.
This group of self acknowledged experts (the Draft EIS contains a letter
in which they say the group "has among its membership experts in many
disciplines related to this problem, including numerous holders of ad-
vanced degrees.") either do not want a decision to be made or are not
capable of making a decision. They say in the Draft EIS that the group
is particularly aware of the "pristine" condition of the York River and
"wish to see no significant alteration of its condition." The Draft EIS
shows that the construction of a York River Facility will improve water
quality in the York River. Mr. Baker in his opening statement said the
Draft EIS was well prepared and that they were in agreement with the
thrust of the document - Mr. Ross Clunis emphasized the environmental
objectives of 92-500, but CBF YC wants no significant alteration of
conditions in the York River even if they are beneficial. CBF YC wants
-------

more study. Perhaps this additional study is desired to feather their
own nests by allowing them to apply for more EPA funded CBF YC sponsored
seminars as each additional study is unveiled. I have seen 7 years
worth of studies relating to the York River Facility including the
Draft EIS. These six documents weigh a total of 16 pounds, contain
2000 pages and over 500,000 words. The bottom line in each of these
studies is that a 15 MGD secondary treatment facility is needed now
and that it is more cost-effective to build a facility at York River
with only minimal adverse impacts both primary and secondary. Addi-
tional study is not needed. I have seen sufficient evidence to make
a decision and I know that EPA has also.
As further evidence of their inability to arrive at a decision,
(CBF YC believes the York to be Pristine and the James to be heavily
stressed) they now pick on their namesake Chesapeake Bay and say
build the facility at Ft. Monroe and discharge into the Bay, even
though their letterhead proclaims "Preserve the Environmental Integ-
rity of Chesapeake Bay". A similar alternative was studied and dis-
carded in 1968 when the PPDC was preparing its 1969 Water and Sewerage
Facilities Plan. It was also studied and discarded in 1972 when HRSD
proposed the construction of the York County Interceptor that was de-
signed to serve a York River Plant location and approved and funded
by EPA. The problems associated with a Chesapeake Bay outfall were
also evaluated in the York River Facilities Plan in 1975. There is
no need to pursue this alternative further.
I personally do not concur with CBF YC's classification of the
York River as pristine. Webster's dictionary defines pristine as char-
acteristic of the earliest, or an earlier period or condition; original;
still pure and untouched. Mrs. Matthews in her statement described how
God created the world. Unfortunately she neglected to point out how
the York - James Peninsula was created millions of years later by those
infamous adverse environmental impacts of erosion, sedimentation and
flooding, not exactly pristine conditions. Surely EPA does not want
to return to the pristine conditions that existed in October 1781 when
the York River assimilated the wastes generated by the 32,140 British,
French and American troops assembled at Yorktown or the 103 ships in
the British Naval Force on the York River or the pristine condition
that existed when Cornwallis ran out of forage for his horses and ex-
peditiously solved the problem by slitting the throats of 400 horses
and casting the carcasses into the York River. This pristine condition

the pristine conditions that existed in 1931 when 300,000 people attended
the 4 day Sesquicentennial where they actually constructed 6 permanent
comfort stations to accommodate the planned attendance of 100,000 people.
I, for one, believe that adequate sewage treatment capacity will be es-
sential for the health and safety of those that will come to visit in
1981 for the Bicentennial celebration.
The Williamsburg League of Women Voters wants a decision on this
facility delayed until the completion of the Hampton Roads Water Quality
Agency 208 Study. I have participated in the past as a member of the
public participation committee of that agency and am aware of the fact
that the HRWQA has accepted the facilities plan as an integral part of
the study. The HRWQA considers that the York River facility will be
constructed by 1980 and that wastewater flows will be treated at the
York River Facility from 1985 on. Therefore, there is no need to de-
lay this project until completion of the 208 Study.
Mr. Flagge, in his testimony, acknowledged the citizen support for
this project while he suggests that the environment continue to be sub-
jected to septic tank effluents such as his, with "77 mg/1 suspended
solids and 305 mg/1 of BOD" as opposed to the secondary treatment con-
centrations of 30 mg/1 suspended solids and BOD of the proposed HRSD
facility. I concur with EPA's Draft EIS conclusions that continued
reliance on septic tanks is not practical and that HRSD's secondary
treatment is adequate.
Mr- Elksnin, as usual, is confused with his facts. He described
the plight of the famous Lynnhaven oyster. The entire Lynnhaven Bay
was closed for the taking of shellfish in March 1975 due to the same
conditions that exist in York County - inadequate sewage treatment,
mainly from malfunctioning septic tanks. At that time you could not
buy a Lynnhaven oyster. The provision of adequate sewage treatment
has contributed to the opening of selected areas of Lynnhaven Bay in the
fall of 1976. Since that time Lynnhaven oyster have reappeared in sea-
food markets.
Mrs. Cooper, Chairman of the York County Board of Supervisors, is
also confused. She voted in favor of the York County resolution re-
questing EPA to give consideration to expansion at the James River.
At the public hearing she personally concurred with the statement of
Mr. McBride of the SWCB in support of the York River Facility.
Mr. Burgess indicated that our problems will be solved by water
conservation. Water conservation practiced by Anheuser BusQh in regard
to the Williamsburg STP has reduced their hydraulic volume but has not

Re: York River Wastewater Treatment Plant
Draft Environmental Impact Statement
Dear Sir:
HRSD concurs with many of the conclusions in the Draft Environmental
Impact Statement for the York River STP. The majority agree with those
obtained in the environmental assessment for the York River Plant pre-
pared by our Consultants, Gannett, Fleming, Corddry and Carpenter, in
December, 1974. It is significant that both EPA and the EIS conclude ,
that at least 15 MGD of additional sewage capacity is required on the
Peninsula. The secondary impacts resulting from new capacity is con-
sidered neither controlling nor sufficiently serious to warrant reliance
on "no action" or "non structural controls" alternatives. Other conc}.u-
sions considered relevant are listed below and quoted from statements in
the EIS. Without a careful reading of the draft, it would be difficult
to appreciate some of these findings.
1. EPA has reviewed the applicant's proposed project and has deter-
mined that the proposed treatment disposal, and disinfection processes
are acceptable.
2. Advanced water treatment units are not required at the proposed
facility.
3. The "no action" alternative (i. e., no new additional sewage
capacity) would have significant adverse impacts upon growth in the ser-
vice area and could promote adverse secondary impacts upon air and water
quality.
4. That EPA generally concurs with the Hydroscience Model which
denotes that discharge from the York River STP would have minimal adverse
impact upon water quality in the lower York River.
-------
Page 2 July 18. 1977_
5. The addition of particulate emissions from the incinerators would
not cause the primary or secondary air quality standards to be violated.
6. No air quality standard should be violated by the secondary im-
pacts of the proposed project.
7. Treatment plant operation will not significantly increase ambient
noise levels.
8. The entire area does have significant visual appeal, but sewage
treatment facilities on the site will not destroy any significant visual
amenities.
9. The effects of the condemnation on oyster production will be
negligible.
Although HRSD supports many of the conclusions in the EIS, there are
basic disagreements with several portions of the draft and with several
of EPA's preliminary draft conclusions. Prior to the June 20, 1977 public
hearing, the District's primary objection to the EIS was EPA's proposal
to construct a 20 MGD increment at the existing James River STP in lieu
of the 15 MGD York River facility. This proposal was not considered either
economically or environmentally advantageous. Not even a preliminary
evaluation was made by EPA of the environmental effects of a 20-35 MGD
additional discharge to the James River (now designated as a National
Priority River). Furthermore, this proposal directly conflicted with pre-
vious EPA actions supporting the York River Plant. The major interceptors
for the York River Plant were constructed with an EPA Grant (C-510465).
These interceptors were sized for a plant on the York River and not as
peripheral sewers for the James River STP. Through statements in the
"errata sheets" issued at the public hearing, EPA concurs that the York
River site is more cost effective than a plant on the James River. A copy
of the Hydroscience testimony (Exhibit A) adequately addresses the environ-
mental impacts of a large incremental discharge from the James River STP.
The following will specifically address EPA's preliminary conclusions
and specific statements on the EIS which require clarification.
EPA Preliminary Conclusion 1
The applicant's proposed treatment capacity of 15 MGD is
sufficient to accomodate maximum wastewater flows projected
by 1995. The applicant's flow projections incorporate a 12.4
gpcd increase in residential wastewater flows between 1980 and
1995 and assume that removal of infiltration/inflow from the
Boat Harbor sewer system is not cost effective. EPA has cal-
culated that maintenance of 1980 residential per capita flows
throughout the Peninsula would reduce projected 1995 resi-
dential wastewater flows by 5 MGD. Cost-effective removal
of infiltration/inflow from the Boat Harbor collection system
could also provide the applicant with additional available
treatment capacity for residential and non-residential waste-
water .
-------
Refer also to pages: xi, S-15, 1-4, 1-11, V-5, V-10, V-25.
HRSD has been a long term advocate of water conservation. In 1972,
i program^was initiated by the District to inform industry and the gen-
sral public of means available to reduce water consumption. Many of the
:ommercial and industrial establishments served by HRSD have responded,
showing dramatic decreases in consumption. Unfortunately, the effect
pf the program on residential users has not been significantly measure-
able - despite a substantial increase in HRSD sewer rates.
Accordingly, current planning for future sewage capacity relied on
predictions available at the time of planning. Exhibit B presents the
documentation for the projected increase in residential sewage flows from
62.7 gpcd in 1980 to 75.1 gpcd in 1995. The 75.1 gpcd was used as a
basis for projecting long range regional planning on Peninsula treatment
capacity. The York River STP is the scheduled treatment facility in the
regional plan as reflected by the existing interceptors for the plant.
Even with no increase in per capita water consumption from 62.7 gpcd,
a 15 MGD York River Plant is still needed. Planned expansion of other
HRSD facilities is not locked into any definite time phase, but will be
made as needed and according to the demands of the system.
Throughout the EIS in general and EPA Conclusion #1 in particular,
it is implied that additional sewage treatment capacity would be avail-
able by removal of infiltration/inflow. At the public hearing, EPA ack-
nowledged that it was not cost effective to remove infiltration/inflow.
Accordingly, the continued references in the EIS to the capacity avail-
able from additional infiltration/inflow removal are no longer germane
and should be deleted.
EPA Preliminary Conclusion 2
The interconnect system has not functioned as the appli-
cant had proposed with the result that two treatment faci-
lities frequently violate their NPDES permit limitations. In
addition, the capacity of the interconnect system to provide
long-term diversion with complete treatment at a second faci-
lity is not sufficient to efficiently utilize the total re-
serve capacity of all HRSD Peninsula treatment facilities.
The applicant has failed to comply with EPA's 1973 pre treat-
ment requirements with the result that the James River and
Williamsburg facilties have experienced operational diffi-
culties from industrial waste discharges.
Refer also to pages S-3, S-15, 1-16, 1-17, 1-18, 1-29,
IV-46, V-18, V-20, V-21.
It is apparent from this statement and other contained throughout
the EIS that the purpose and operation of the HRSD interconnector system
is not understood in the draft. The intent of the SWCB directive to
interconnect the Peninsula systems was to a) increase system relia-
bility; b) maximize existing capacity. HRSD & and State never considered the
-------
Page 4 July 18, 1977
system would be utilized to accept all the flow from a plant experiencing
major failure. Nor did they intend the system to allow the District to
violate long-term planning of defined service areas. Instead, the inter-
connection allows for temporary diversion from a plant experiencing
operational difficulties or an overloaded system or pump station, and an
alternate route for sewage in case of line or pump station failure. As
in the case of York County, it enabled the District to temporarily extend
service boundrles of existing plants to provide needed sewage treatment
capability long before construction of the York River Plant.
The interconnect system allows HRSD some flexibility to define the
service area of Its plants. However, the process is not arbitrary as
suggested by EPA. The decisions are based on conditions and character-
istics of systems and pumping costs as well as development and growth
patterns in an area. The system model proposed by Gannett, Fleming,
Corddry and Carpenter will enable HRSD to more efficiently predict line
pressures resulting from projected flows and the effects of proposed
emergency or minor permanent service area changes, procedures which now
consume considerable time.
As portions of the interconnect system on the North Shore have
either recently been completed or now are under construction, its use has
been somewhat limited. Flow transfer between Williamsburg and James River
was not possible until mid-1976. Due to available capacity and opera-
tional difficulties at these plants, it was HRSD's decision not to trans-
fer any flows in recent months. Diversions from James River to Boat
Harbor STP will be limited until the Boat Harbor influent line is rein-
forced (now awaiting resolution of PG-62). The system, although incom-
plete, has already increased system reliability. Flows have been diverted
from several overloaded pump stations in the Boat Harbor area to prevent
bypasses and to allow repair of force mains with a minimum of sewage
overflow.
Hampton Roads Sanitation District has been acutely aware of treat-
ment difficulties at the Williamsburg Treatment Plant and those occas-
sionally experienced at the James River Plant for the past several years.
The District has expended considerable effort in trying to optimize treat-
ment processes and meet effluent limitations as specified in the NPDES
permit. In addition, many studies of influent wastes to the plant have
been accomplished. These studies have included wastewater character-
ization, effects of mixing of various waste streams, and effects of load-
ings (hydraulic and organic) on the treatment plant itself. This work
has culminated in our belief that the Williamsburg Treatment Plant cannot
successfully treat waste as are presently discharged from the Anheuser-
Busch Brewery. Treatment difficulties at James River have never been
conclusively attributed to an industrial discharge.
Hampton Roads Sanitation District has enforced a pH effluent limi-
tation on Anheuser-Busch since 1972. This limitation is in keeping with
those promulgated by EPA in 1973. Even though these effluent limitations
state that no discharge shall be allowed which impairs treatment struc-
tures and processes, HRSD had not satisfactorily concluded that the
Brewery wastes could not successfully be treated at the treatment plant
until mid-1976. In absence of specific EPA pretreatment requirements for
brewery wastes, HRSD has attempted to define reasonable standards during
-------
Page 5 July 18. 1977
the process of optimizing treatment. Negotiations to implement these re-
quirements are ongoing and will continue until problems associated with
waste treatment at the Williamsburg Plant are solved.
EPA Preliminary Conclusion 3
Regionalization of treatment capacity at the site of
the existing James River facility would provide HRSD with
long-term cost savings. Constructing a 20 MGD facility at
the site to incorporate the 15 MGD proposed capacity for
the York River STP and a proposed 5 MGD expansion of the
James River facility would save HRSD approximately $450,000
in capital costs and $29,000 annually in operation and
maintenance costs.
Refer also to pages: S-15, V-18, V-19, V-22, V-23.
The cost analysis and the resultant EPA preliminary conclusion #3
were revised by the "errata sheets" issued at the public hearing. In
essence, the "errata sheets" noted that the cost differences between build-
ing a 20 MGD plant in 1981 versus providing 15 MGD of capacity in 1981,
followed by 5 MGD in 1991 were negligible. More importantly, they con-
firmed that construction of a 15 MGD York River Plant is more cost-
effective than expansion of the James River Plant by 15 MGD.
Based on the review of the "errata sheets", our consultants still
have doubts regarding the procedures which were used for conducting the
present worth analyses as well as the logic used in assessing the feasi-
bilities of phased construction. While the EIS methodology and its appli-
cation to the EPA document "A Guide to the Selection of Cost-Effective
Wastewater Treatment Systems", (EPA, July 1975) cannot be accepted, the
revised Preliminary Conclusion Number Three, as contained in the "errata
sheets", better reflects the results of our own independent analysis.
Nevertheless, it is believed that the prepared testimony by Gannett,
Fleming, Corddry and Carpenter, presented at the public hearing, is still
pertinent and accordingly again will be filed with EPA (Exhibit C).
EPA Preliminary Conclusion 4
The applicant's proposal to rely upon incineration as
a sludge volume-reduction technique in an AQCR for particu-
lates requires further evaluation. HRSD should formulate
a comprehensive sludge management program for all of its
treatment facilities on the Peninsula and continue to eval-
uate land application as a disposal alternative.
Refer also to;pages: S-4, S-15, xii, 111-16, IV-48, V-io-18.
-------
Page 6 July 18. 1977
EPA's concern over particulate emissions is unclear, as the EIS
stated that no secondary or primary air quality standards would be vio-
lated by the Boat Harbor incinerators. To clarify any ambiguity, HRSD
is submitting the Boat Harbor Compliance Test for Particulate Emissions
(Exhibit D) which states the incinerator meets air quality standards.
Incineration is presently the major thrust of HRSD's sludge manage-
ment program. It is the product of an extensive effort by HRSD to find
a reliable and economically and environmentally acceptable sludge disposal
method. Land application has been the traditional means of sludge appli-
cation for the District since its inception. The James River Plant con-
tinues to rely solely on land application. HRSD has applied liquid sludge
via tank trucks, spray irrigation and plow injection. Dried sludge from
lagoons and drying beds has also been applied to the land. In recent
years, the spread of residential development and increased quantities of
sludge have reduced the availability of disposal sites. The relatively
high groundwater table, the number of reservoirs, and concern over drain-
age to shellfish areas has made it difficult to locate new sites. In one
year, the District examined almost 60 areas extending from North Carolina
to the suburbs of Richmond to the mines in the Western portion of the
state, before a suitable location could be found to dispose of sludge
from an upset digester. A good sampling of these problems is indidated
in the EIS appendix where requests to receive composted sludge were re-
ceived with "little" enthusiasm.
To obtain a reliable sludge disposal method, HRSD made the committ-
ment to incineration in 1972. It is recognized that incineration is ex-
pensive and wastes a potentially valuable resource. Thus, the District
continues efforts to find other alternatives. At considerable expense,
HRSD piloted a sludge dryer. Purifax was also used. A small scale com-
positing study will begin this fall. Underway at the Atlantic Plant site
is the most extensive effort in Virginia to study the viability of land
application. This project, initiated by HRSD, has just received EPA fund-
ing as a portion of the Step I Atlantic Plant Grant.
Hayes, Seay, Mattern and Mattern made an extensive study to cover
available sludge options for the District thru 2000. The study includes
potential sites for sludge disposal on the North and South Shores. How-
ever, until the results of the Atlantic Plant project can conclude that
land application is environmentally and economically acceptable for this
area, incineration will be the main sludge disposal method for the
District.
EPA Preliminary Conclusion 5
The principal, primary, long-term impact of the appli-
cant's proposed project will be a substantial increase in
point-source pollutant loading of the lower York River.
During normal operations at 15 MOD, the proposed facility
will discharge 3750 Ibs/day BOD, 2500 Ibs/day ammonia-nitro-
gen, 4380 Ibs/day total nitrogen, and 1000 Ibs/day total
phosphorus into the estuary. These loadings will increase
the average concentrations of total phosphorus in the estuary
-------
Page 7 July 18. 1977
by approximately 20% and total nitrogen by approximately
10%. According to a model of the estuary, this nutrient
addition will increase maximum chlorophyll concentrations
to approximately 50 ug/1. However, the effects of failing
septic tank systems on groundwater, surface waters and
public health. Additional study may also be needed to
compare the loading effects of the proposed York STP versus
the alternative of the James River STP expansion.

The enclosed copy of (Exhibit A) of John St. John of Hydroscience
adequately addresses this conclusion.
The following attachment "A" addresses specific items in the EIS
which also warrant your attention. I hope our comments have been helpful,

Dear Mardene:
Re: York River Wastewater Treatment Plant
Documentation of Increasing Water Consumption
As requested in the Draft EIS on the York River Wastewater Treatment Plant,
we are documenting in this letter the basis for the projected increases in per capita
water consumption used in the development of wastewater flows. In our Preliminary
Engineering Report on the York River Wastewater Treatment Plant, we indicated that per
capita water consumption is likely to increase for the foreseeable future, based upon
estimates made by Pitometer Associates for the Newport News Water System, on long-
term projected trends in water consumption, and on projections of the Virginia State
Water Control Board.
Long-term trends in most areas show that per capita water consumption is
increasing. This is particularly the case on the Virginia Peninsula, as is well doc-
umented in the 1972 report by The Pitometer Associates on their Engineering Study of
the Newport News Water Distribution System. Table Number 5 of the Pitometer report,
enclosed herein, presents over 20 years of water consumption data for the Newport
News Water System service area. This data is displayed graphically in Chart Number 2
of the report, which is also enclosed. The long-term per capita water consumption
trend is obviously toward increasing consumption.
We analyzed the per capita water consumption data for both 20-year and
10-year trends using a least squares fit. The results of the analysis show a long-term
(1951-1970) trend of consumption increasing at 1.42 gallons per capita per day per
year (gpcd/year), and a more recent shorter term (1961-1970) trend at a 2.43 gpcd/year
rate of increase. This analysis also indicated that there is an apparent positive
rate of increasing water consumption rates.
-------
Mrs. Marjorie McLemore -2- July 18, 1977
Project Coordinator,
York River EIS
The Pitometer report also developed projections of per capita water
consumption, which are presented in the enclosed Chart Number 2. These projections
began with a higher per capita rate of increasing water consumption (6 gpcd/year for
1972-1977), with lower rates farther into the future (1.2 gpcd/year for 1977-1982
and 1.0 gpcd/year for 1982-1987).
In projecting future water consumption and wastewater flows for the York
River Facilities Plan, we were cognizant of the increased interest in water conser-
vation on the part of the general public and as mandated in Public Law 92-500. How-
ever, we were also obligated to provide for wastewater needs based upon a realistic
evaluation of actual conditions. Therefore, we projected a continuation of increasing
per capita water consumption, but at a lesser rate than that projected by Pitometer
Associates. Our projections were for a rate of increase of 1.0 gpcd/year for the
near future (until 1990), decreasing to 0.5 gpcd/year after 1990. For the period
1980 to 1995, this corresponds to 12.43 gpcd after adjustment for water not discharged
to'the sewer system, as compared to 15.4 gpcd as provided by Pitometer Associates.
The increase of 12.4 gpcd is approximately one-half of the increase that would be
justified by extrapolating past trends.
We are aware of the recent public information program developed by the
HRSD directed toward water conservation, but the effect of such a program is gradual
and cannot be quantified until it has been underway for several years. The projections
of wastewater flows must balance anticipated decreases in water consumption with doc-
umented historical trends. We believe that the projections developed by us provide
that balance and are the most accurate and realistic projections available for the
Virginia Peninsula. To project any lower water consumption (and wastewater flows)
would not be responsible planning toward the elimination of public health hazards
and protection of water quality.
Please feel free to contact us should you have any questions concerning
this information.

HRSD has projected 182,000 Ibs/day
of sludge will be produced at a 20%
cake. Incineration capacity at the
Boat Harbor incinerator is 810,000
Ibs/day of a 20% cake. Boat Harbor
will produce secondary and primary sludge.
York River sludge will be roughly equi-
valent to 50% of the total sludge burned
in 1995, provided only York River and
Boat Harbor STP sludge are incinerated
at this site.
The emissions data is now available and
is enclosed as Exhibit D. Refer to

clusion #4.
According to figures on IV-30, the

not be necessary.
The average Family (HRSD) quarterly
User Rate is $15.50 not the $22.00
indicated.
Land Use Impacts - EPA is referred to
the York County Zoning Ordinance

expansions to follow later when required.
The proposed Peninsula treatment
capacity is thus 64.6 MGD. When flow
projections are compared to this figure,
a 3.9 MGD deficit results in 1995
(Table on page V-10).

Status of the York River, Virginia in Relation to the Proposed
York River Sewage Treatment Plant (STP)
The Institute has reviewed the DRAFT Environmental Impact State-
ment on the York River Sewage Treatment Plant and is seriously concerned
that the present status of the river was not adequately considered in
developing the impact statement.
There are four areas of principal concern, these are:
1) Oxygen depletion
2) Phytoplankton growth and population changes
3) Loss of potentially productive shellfish grounds
4) Potential impacts of the plant on the use of the river
and its water for research purposes.
We will develop our concern for each of these areas separately
in the following sections.

SYNOPSIS OF SUMMER DISSOLVED OXYGEN CONDITIONS IN THfe LOWER YORK RIVER,
1960-1976.
Oxygen conditions in the lower estuary are difficult to compare
because of the paucity of data in certain years and because of the often
complex and dynamic vertical and horizontal distribution of dissolved 02.
The following summarizes* data available in the VIMS hydrographic data
base and in various reports and publications by Institute staff. Almost
no reliable data on dissolved G£ concentrations in deeper waters of the
lower York prior to 1960 are available from these sources.
I960 Patten et al. conducted productivity experiments at the "plankton
buoy" station located directly off VIMS in 9 m of water (approx-
imately river mile 4.5). Experiments were conducted from June 22
to October 11, thus abundant data are available. Bottom dissolved
oxygen concentrations during the summer ranged from 2.70 - 6.14
mg/1. Most values were in the 4.5 - 5.5 mg/1 range, but levels
below 4.0 mg/1 were found on 4 of the 16 sampling occasions, and
only once was the DO much below 4 mg/1 - 2.7 (August 24). Bottom
values were considerably lower than those just above the bottom
due to benthic oxygen demand. DO at 7 m was never below 4 mg/1.
1961 Patten continued experiments during the early summer of 1961.
The lowest DO value observed on the bottom (9 m) was 5.92 mg/1.
1962 Essentially no relevant data from the summer of 1962 were uncovered.
1963 Patten and Chabdt conducted 8 factorial productivity experiments
at the plankton buoy from 24 June to 14 August. Bottom D.O ranged
from 3.35 - 6.16 mg/1 and was reduced below 4 mg/1 (mean 3.7 mg/1)
through 15 July, however DO at 6 m remained dbove 4 mg/1.
1964 Few data are available from the lower York River. Collections
at the mouth of the river (YOO) showed 6 mg/1 at 15 m in May, a
low value of 1.1 mg/1 at 12 m on 23 June, ancfl 5.3 and 6.7 mg/1
deeper than 15 irl in July and September, respectively. Surface
DO was reported as 4.0 mg/1 on 23 June. The^e low values must
be regarded with some caution since they represent single samples.
1965 Relevant data are sparse to non-existent.
1966 Data are available for YOO for May, June, July and August. 5.1 -
6.9 mg/1 were found at 10 m except on August 23 when the DO level
was reported as 4.2 mg/1.
1967 Relevant data are extremely sparse.
I968 Brehmer conducted hydrographic surveys of the major Virginia
subestuaries and visited one station (river mile 4-5) in the
lower York monthly on slack water runs. DO levels in May and
June were 76 mg/1 at 11 m. On July 16 4.93 mg/1 were found at
15 m and on Sept. 10 4.54 mg/1 were found at 11 m.

Dissolved oxygen in the bottoto water remained 3-4 mg/1 into
October. For the first time in the available data we see evidence of
fairly persistent low oxygen levels throughout the summer.
1972
Regular sampling of 6 stations in the lower York by Jordan began
in the spring, just before the arrival of Tropical Storm Agnes.
The figure below shows mean DO values at 12 m for 1972 and 1973
and values at station 4 (off VEPCO) for 1974. DO was reduced
at about the time of Agnes to <3 mg/1. After a slight rebound
in mid-July it was again very low through late July and August
(<3 mg/1).

1973 DO in bottom water again was drastically lowered in 1973 but
did not fall to very low levels until late August. It remained
low until late September. Water containing 2 mg/1 of DO was
found within 8 m of the surface in early September.
1974 Jordan conducted an extensive study of dissolved oxygen conditions
in the lower York River during May - October. Low oxygen con-
ditions developed in deep water in early June. The density
stratification and oxygen clinograde was periodically broken
down and reformed resulting in at least 5 episodes of oxygen
reduction followed by "ventilation" throughout the summer.
This conforms with Haas' observations of the dynamic nature
of the thermohaline structure of the York. Jordan also observed
lowered DO throughout the water column (below the state standard
of 5 mg/1) after an extended period of overcast skies. On the
average 34% of the volume of the river (below 8 m) and nearly
half of its bottom area was affected by <5 mg/1 water.
1975 Physical Oceanography slack water runs sampled river mile 3.6
on May 15, September 19 and October 15 and found in excess of
5.2 mg/1 at 11 m. However no data are available from June -
August.
1976 Physical oceanography slack water runs on May 15, June 7 and
September 13 show no unusually low DO values. However, synoptic
sampling at several stations in the lower river by Physical
Oceanography on 30 June and 1 July for the 208 study showed
probably the worst DO conditions yet witnessed in the lower
York. At a station near Jordan's station 4 off VEPCO DO in
the 8-11 m layer was found to vary from 1.9 - 4.3 mg/1 (mean
2.7 mg/1). Lower DO levels were found at stations near the
Gloucester Point - Yorktown constriction. Here a value of
0.4 mg/1 was found at 10 m although the levels there averaged
about 2.2 mg/1. Occasionally the low DO water reached the
surface and levels of 3-4 mg/1 were found in surface water
samples.
Ichthyology samples in the lower York taken on 21 July also
showed low DO conditions;near Jordan's station 4 3.7 mg/1 was
found at the surface and 2.6 mg/1 at 7 m. DO levels in surface
water were about 4 mg/1 at several of their stations.
Conclusion:
Because of the paucity of data from many years and the known
dynamic nature of the oxygen depletion phenomenon it is not possible
to statistically demonstrate a worsening of oxygen conditions in the
lower York River. Nonetheless the low DO values observed in recent
years fall outside the range of the extensive observations in the early
1960's. In the 1960's values of <4 mg/1 were not witnessed within 7 ra
of the surface. This condition was observed on several occasions during
1971, 1972, 1973 and 1976. According to Jordan an average of about one-
third of the volume of the lower York River fell below the state long-term
-------
-5-
standards of 5 mg/1 during the summer 1974 (not a particularly severe
year). Furthermore, this oxygen deficient pool blanketed about one
half of the bottom area of the river, and much of this area experienced
<3 mg/1. The oxygen clinograde usually intersects the shoulders of
the channel, thus a slight rise in the depth of the oxygen deficient
zone, say to 5 or 6 m, will affect a very large area of river bottom.
Substantial changes in the benthic biota of the deeper portions (> 7 m)
of the lower York River have been documented since 1972 and these are
thought to be, at least in part, attributable to these degraded oxygen
conditions.
Impact of the Proposed York River Sewage Treatment Plant:
Adequacy of model in simulation of complex physical system -
Previous investigations (particularly those by Jordan and Haas) have
shown that the circulation and thermohaline structure of the lower
York River is extremely complex. The lower river exhibited periodic
stratification and destratification, the cause of which, to our knowledge,
is not explained by variation in freshwater inflow. Also noteworthy
is the response of the river following several overcast days, wherein
4-5 mg/1 DO water was observed at the surface by Jordan.
f
We also note that in earlier reviews of the Hydroscience model
by VIMS' physical oceanographers that the salinity verification of the
model is questionable and no attempts have been made to simulate and
verify the present water quality conditions. All things considered,
we have grave reservations regarding the accuracy of the model's pre-
dictions. Furthermore, the model fails to estimate the effect on
dissolved oxygen distribution of the nutrient additions. Since mass
discharge of total N is greater than that of BOD, given any reasonable
C:N ratios for organic matter produced, it is obvious that the oxygen
demand of organic material which could be secondarily produced through
nutrient stimulation may far outweigh BOD discharged by the STP. And
this N can be used again and again in the production of new carbon!
Phytoplankton Response
Background - The EIS treats the effects of nutrient enrichment
only in terms of increases in standing crop, .i.ja. chlorophyll £. It
concludes that an increase in 5 jig/1 is likely and then compares this
increase to other situations where nuisance blooms occur. Since the
present standing crop levels are well below nuisance levels, the con-
clusion is reached that no significant impacts will occur. This approach
is very much an oversimplified one. At present the average chlorophyll a
levels are usually between 5-10 >ig/l, an increase of between 50 to 100%
can hardly be expected to be insignificant. More importantly are the
potential changes which might occur in species composition. As a measure
of potential impact in this regard, we have summarized the impacts which
-------
dlnoflagellate blooms have on oyster growth.
We began weighing oysters under water as a measure of growth
(shell accretion) and to monitor diseases in the mid 1950's. In the
1950.'s, oysters grew continuously through the warm season from about
1 April to 15 December each year. Growth was fastest: in May-June and
slowest on the two cold ends of the growing season. Temperature was
the chief limiting factor provided diseased and sick oysters were
ignored or removed.
In the 1960's, slummer growth was frequently interrupted by
red tides (dinoflagellate blooms) beginning about 10 July and continuing
4 to 6 weeks depending tlpon weather (temperature) andl other factors.
In the wet years! of 1971 - 1975, a new 4 to 6 week period of
no growth was added in April and early May. This stoppage was also
associated with dinoflagellate blooms. The species involved in both
spring and summer blooms varied from year to year, there were no large
red tide blooms in the summer of 1976 or the spring of 1977 and oyster
growth was not interrupted.
We believe that these red blooms are associated with high
nutrient levels in the water, and they seem to be associated with wet
years and abnormal runoff.
Potential Impact of Nutrients from the STP
It is not possible to predict with accuracy the impact of
nutrient additions from the York STP on the composition of the phyto-
plankton community. However, as shown above, if nutrients released
from the plant were to cause a shift in the plankton community to
increased populations of dinoflagellates, a very serious impact on the
oyster industry in the York could result.
Red tide bloom formation has been studied rather extensively
and the causative agent or agents have yet to be identified. Therefore,
if the STP caused shifts in the plankton community, the addition of
nutrient removal for N and/or P would not necessarily reverse the
situation.
Loss of Shellfish Grounds
It is our opinion that the EIS treats the condemnation of
1500 acres of oyster grounds too lightly. Although of little economic
importance at the present time because of the existence of MSX, the
development of hatcheries to produce disease resistant oysters at
some point in the future could make this a valuable oystering area
again. An acre of productive oyster ground, not of the highest quality,
-------
-7-
can be expected to yield a profit of about $$00/acre/year (Haven,
personal communication). If relaying is necessary, the potential
profit is reduced by at least one half; therefore, uding these
estimates one could project the potential loss, due to the projected
closure, of over one half million dollars per year.
Potential Impact on the River as a Research Asset
The Commonwealth: of Virginia maintains its main marine research
facilities, valued at over 4 million dollars, with research, advisory
service and educational operations totaling around 8 million dollars,
on the shores of the York River. VIMS draws water from the river for
the culture of sensitive marine organisms and also utilizes it as a
source of dilution water for numerous types of bioassay experiments.
If toxic materials were to enter the river from the sewage system,
they could seriously jeopardize this research operation and continued
utility of the facility. Since the plant will be interconnected with
others in the area which have industrial inputs, this concern is even
greater than it would be for a strictly domestic system. The recent
problems with the release of toxic wastes into the Williamsburg Plant
are an example of this concern. In addition, the introduction of
persistent chlorinated organic compounds which will not be neutralized
by dechlorination, could affect our water supplies.
It is difficult to gage the exact magnitude of this potential
problem because of the uncertainty as to the composition of the effluent.
We feel, however, that the risk is significant and that a substantial
public resource may be affected.
Overall Impact
The staff of the Institute believes that environmental conditions
in the Lower York River have been deteriorating over the past 10 years.
This trend is most evident in the dissolved oxygen conditions and is
also indicated by declining and/or interrupted oyster growth rates.
If the plant is allowed to be built, it is our opinion that
monitoring of environmental conditions in the river should be required.
If such studies show conditions to be changing as a result of the
discharge, corrective measures should be mandatory. The river monitoring
should include comprehensive studies of dissolved oxygen distribution,
phytoplankton populations, and toxic substances.

Gentlemen:
Noting that today is the closing date for supplementary
comments on the draft Environmental Impact Statement for the
proposed York River STP, 'we request your indulgence for the
brevity of this communication. The magnitude and complexity of
the matter has resulted in the impossibility of full treatment
within the present time limit. Consequently, we here treat
several topics very briefly, and will provide extension of our
remarks on these and other topics where advisable.
The topics we include here are:
1) York River Site Planning
2) I/I Problem

4) Letters from HRSD, PPDC
Site Planning The draft EIS does not treat the planning nor
refer to the planning reports that led to the Goodwin Neck
site for the proposed York River STP. There is no listing of
these references in the GFCC York River STP "Preliminary Eng-
ineering Report", 1974, but a listing does appear on pagge 2-3,4
of the "Boat Harbor Water Pollution Control Plant Phase II1
Report^; April, 1975, from Hayes, Seay, Mattern and Mattern. We
have not yet been able to examine the Buck, Seifert and Jost
1968 report to verify that the Fort Monroe/Buckroe Beach site
was considered (a copy was not available in the Peninsula Plan-
ning District Commission library), but in any event, conditions
today are much different than they were in 1968. We have re-
examined the Malcolm Pirnie reports and confirmed our view
that the planning is typical of pre-PL 92-500 sewerage reports.
'I Problem We were informed at the hearing on June 20th that
le EPA had decided that'it was cost effective to treat the
Infiltration/Inflow in the Peninsula system, i.e. to pass it
through larger capacity STP's rather than to correct it. We
have requested information on the basis for this decision,
since the I/I in the Boat Harbor system is such a large propor-
tion of the total flow, and we believe any such decision must be
arrived at only after consideration of all the factors involved.

The term "cost-effective" has implication of a restricted scope
in factors. The requested information is urgently needed for
review.
Recent Related Events The events below have all occurred since
t^ie June 20th hearing, and all relate to questionable aspects
of the planning for the proposed York River STP, which must be
adequately dealt with prior to any decision on the York River STP.
a) Anheuser-Busch Brewery Expansion (clipping) Though the ₯111-
iamsburg STP designed capacity of 9.6 mgd should provide
sufficient capacity for the additional 2.8 mgd wastewater
flow, the recent problems show that HRSD must impose appro-
priate effluent requirements on Anheuser-Busch, so that the
Williamsburg STP can in turn meet its effluent requirements.
b) Peninsula Population (clipping) This is another in a contin-
uing series of reports which show continuing reductions in
the population projections for the Peninsula.
c) Fort Monroe Site (clippings) This continuing situation adds
credence to the practical possibility of the proposed "fur-
thest downstream" Buckroe/Fort Monroe site for an STP for Hamp-
ton wastewater flows.
d) Fairfax County (no clipping) A brief citation in the June
issue of the "Water News" from the Virginia Water Resources
Research Center at VPI&SU at Blacksburg led us to an encour-
aging article in the June 20th issue of the Richmond "Times-
Dispatch" referring to the Fairfax County Difficult Run Pump-
down project, in which an EPA Region III spokesman was
quoted as stating the EPA must give priority to cleaning up
the environment and to clean water, with projects to cope
with a community's growth to be of secondary importance.
Letters from HRSD and PPDC (copies herewith) These letters are in
response to ours to Mr. Cox on June 25, 1977, a copy of which
you have. They have not yet been answered. They appear to show
a rather complete lack of understanding of our position. We
will forward copies of our respective responses.
Concluding Remarks We intend to conduct further researches into
the shellfishing situation in the neighboring waters. We also
intend to comment on additional aspects of the York River STP.
We continue to believe that time is available for resolution of
the many questions that have been raised, so that a more reason-
able decision on additional STP capacity for the Peninsula can
be reached than is possible under the present circumstances.

Subject : Comment on Draft Environmental Impact StatementYork
River Wastewater Treatment Facility, York County,
Virginia--EPADEIS #7706.06.
The draft environmental impact statement that accompanied your
memorandum of June 6, 1977, has been received by the National Mar-
ine Fisheries Service (NMFS) for review and comment.
The statement has been reviewed and the following comments are
offered for your consideration.
General Comments
In our opinion, the DEIS contains sufficient biological and envi-
ronmental information to allow an adequate evaluation of the STP's
impacts on the local aquatic resources. However, several sections
describing plant operation and construction should be covered in
greater detail. In addition, it would appear that the majority of
the project's beneficial impacts could be achieved by enforcing
improved septic tank and land use codes along with expansion of the
existing HRSD treatment facilities. We also note that many of the
STP's adverse impacts are to be mitigated through enforcement of
environmental legislation and regulation. Since existing regulations
governing septic systems etc. are apparently not being enforced in
York County, adherence to these new regulations is doubtful (see
page 5-16, V-24, V^.25) . It should be noted that of the 42 impacts
associated with the proposed project, 33 or 78.6% are listed as
adverse. In conclusion, the various contradictory statements con-
cerning the balance of the postulated surface v;ater quality benefits
resulting from closure of failing septic systems and inauequate
package treatment plants against the projected adverse impacts of
increased urban runoff that would result from project-stimulated
construction should be clarified.
The statement on Page IV-48, paragraph 4, "The beneficial impacts
resulting from improved water quality may offset the adverse impacts
resulting from increased flow variations and increased urban runoff."
typifies these statements and appears to eliminate the major posi-
tive benefit claimed for the project. In short, it would appear
-------
August 5, 1977
Page 2
that the entire project is based on a benefit which, will be totally
eliminated by the secondary growth induced and permitted by project
construction. It is our opinion that this secondary growth will
have a significant adverse impact on the aquatic resources within
the project area not to mention the loss of 1,500 acres of poten-
tially productive shellfish grounds as a direct result of the plant's
effluent condemnation zone.
Specific Comments
Section II
ENVIRONMENTAL SETTING
A. NATURAL ENVIRONMENT
7. Biology
Aquatic Fauna
Page 11-41, paragraph 2. The final sentence in this paragraph
indicates that MSX and natural predators have practically elimi-
nated all oyster production in Lower Chesapeake Bay and its trib-
utaries. While it is true that MSX has reduced the oyster produc-
tion to a very low level, efforts are being made to solve the
problem (see comments on page IV-34, paragraph 6).
Page 11-42, paragraph 2. Harvest figures for the commercially
important species mentioned in this paragraph should be included
in this section. We have included a table of catch statistics
for the lower York River (Naval Weapons Station to the river mouth),
giving the 1976 data for your review and inclusion in the final
EIS. The table also lists the shellfish harvest for this reach of
the river discussed on previous pages in the DEIS.
Section IV
IV. ENVIRONMENTAL EVALUATION OF APPLICANT'S PROPOSED PROJECT.
A. Environmental Impacts of Applicant's Proposed Project
Page IV-1, paragraph 1. This paragraph indicates that many of the
project's adverse impacts can be minimized or mitigated through
careful planning and enforcement of regulations designed to protect
environmental quality. This statement becomes suspect when we con-
sider the statements on pages S-16 and V-24, which indicate that
the present standards for septic tanks are ineffective, the minimum
lot size is too small, and the York County Health Department has,
historically, poorly enforced this inadequate standard. We see no
reason to believe that these new criteria, posed as mitigative
measures, will fare any better than present regulations. This will
-------
August 5, 1977
Page 3
result in project damage to aquatic resources. In addition,
paragraph 2 indicates that many of these mitigative measures will
require the development of new and complex programs to ensure their
success. These programs should be described and their potential
effectiveness evaluated.
1. Surface Water Quality
Page IV-9, paragraph 1. This paragraph indicates the STP effluent
will be discharged through the outfall of the VEPCO plant located
on the York River adjacent to the proposed STP site. This section,
however, does not discuss the potential effects of the VEPCO plant's
heated effluent on biocides in the STP effluent. The potential for
a continuous plankton bloom at the discharge pipe, as a result of
the mixing with heated effluent, should be discussed. In addition,
the potential interaction of the combined effluent from the STP and
VEPCO plants with the adjacent Amoco refinery should be considered.
Finally, Virginia Institute of Marine Science (VIMS) has detected
a trend in DO reduction within the York River beginning in the early
1950s (Tom Barnard, VIMS, Gloucester Point, Virginia: personal
communication). This fact should be discussed and related to the
model prediction concerning dissolved oxygen concentrations.
These topics should also be related to Section 6. Biology on page
IV-24.
Page IV-10, paragraph 3. Increased urban runoff will enter the
streams within the study area as the area develops in response to
the project. The extent to which increased urban runoff pollutes
local streams will have a direct effect on the proposed project's
effectiveness in improving surface water quality. Since the elimi-
nation of failing septic tanks and small sewage treatment plants is
a major project benefit, calculation of the difference in projected
benefits from removal of these sources from the increased urban
runoff is critical to project success. Because urban runoff contains
heavy metals, petroleum extracts, pesticides, organic waste, sus-
pended solids, and nutrients, it is more detrimental to aquatic
resources than simple septic leacheate or treatment plant effluent.
In addition, upland runoff has been found to leave very high coli-
form counts, and it therefore appears unlikely that any presently
condemned shellfish areas would be opened as a result of project
construction. In summary, we would take issue with the DEIS con-
clusion (page IV-12, paragraph 3) that the reduction of point source
loads may be reduced sufficiently to allow the receiving streams to
-------
August 5, 1977
Page 4
assimilate the increasing load from non-point source urban runoff.
While this may occur in the short term before significant project-
induced construction takes place, it is our opinion that the long-
term effects of increasing urban runoff will have a decidely
adverse effect on the aquatic resources within the STP's service
area.
6. Biology
Page IV-24, paragraph 4. This section again indicates that the
project's primary beneficial impact will be the improvement of water
quality in the small tributaries to the lower York River. As stated
in the preceding paragraph, it is the opinion of NMFS that these
projected benefits will not be realized and that, in fact, the re-
sultant water quality degradation from increases in urban runoff
will actually effect a net reduction of water quality. This very
fact is alluded to in the third paragraph on page IV-25 which states:
"The adverse results of flash flooding, low stream flow, and pollution
from urban areas may negate the beneficial impacts expected from the
relief of clustered treatment plants and septic tanks." Thus, this
project is, in fact, simply providing a vehicle by which construc-
tion can continue in an area that, by its very physical features,
is not suited for either residential or commercial development, and
that this development with its secondary impacts will result in
adverse impacts to aquatic resources, including the closure of 1,500
acres of potentially productive shellfish beds in the York River.
Page IV-26, paragraph 3. We do not agree with your conclusion that
the effects of salinity changes will be minor. The marine organisms
present within the project area are conditioned to the various
salinity ranges that exist at present. While they are able to tole-
rate moderate changes in salinity, any significant shift in salinity
will result in a concurrent shift in species distribution. In
addition, significant short-term influxes of fresh water such as
Hurricane Agnes, 1972, can cause a shellfish mortality- The likeli-
hood of this occurring in the project area increases with the rise
of urbanization.
12. Social and Economic Impacts
Page IV-34, paragraph 6. This paragraph indicates that the con-
demnation of 1,500 acres of shellfish leases and grounds will have
a negligible effect on oyster production. While this is generally
true at present, it should be noted that plant location at this
site will result in the permanent closure of 1,500 acres of oyster
grounds which will preclude their return to productive use in the
future. In addition, fourth generation oysters resistant to MSX
are presently being cultured in the laboratory at VIMS. This and
other experimental work presently being conducted on solving the
MSX problem indicate that the problems are not insurmountable,
leading us to conclude that the oyster bars in higher salinities
-------
August 5, 1977
Page 5
will again become productive. Thus the closure of 1,500 acres of
potential oyster grounds is, in our opinion, not insignificant.
Page IV-37, paragraph 1. If MSX is eliminated as a problem, as
discussed in the preceding comment, we believe that seed oysters
of a resistant strain will again be planted in the York River.
Page IV-37, paragraph 2. While commercial harvesting of hard clams
in low-density areas (less than 23 bushels/acre ) is not feasible,
the reason for the low density of hard clams in the condemnation
area should be investigated. If the area is potentially useatxLe
for clam production, then the loss of this potential area is more
significant than indicated in the DEIS.
B. Adverse Impacts Which Cannot Be Avoided
Page IV-44, paragraph 2. This section again indicates that enforce-
ment and implementation of the appropriate environmental protection
measures will be required to mitigate or reduce many of the project's
adverse environmental impacts. As indicated in our earlier comments
on this subject, we see no reason to believe that the present lack
of enforcement of existing standards by York County will change
(page 5-16, V-24, V-25) and are therefore skeptical of the useful-
ness of these proposed new regulations to reduce the project's
adverse impacts on the marine environment.
C., Relationship Between Local Short-term Use of Man's Environment
and the Maintenance and Enhancement of Long-term Productivity.
Page IV-46, paragraph 1. This paragraph states: "The requirement
for treating wastes at the proposed site has not been demonstrated."
and that "Capacity is available at the James River and Williamsburg
facilities." Given these two statements, we question the need for
the construction of the STP at this location with its associated
environmental disruptions. This position is further strengthened
when we consider the statement on page IV-48, which indicates that
the projected surface water quality improvements may offset the
adverse impacts resulting from increased flow variations and increase
urban runoff.
SECTION V
V. IDENTIFICATION AND EVALUATION OF ALTERNATIVES TO THE APPLICANT'S
PROPOSED PROJECT
Page V-l. While this section generally addresses the various
alternatives to the project, we note that no consideration has
apparently been given to actually locating the proposed STP at a
site other than the proposed York River location. This topic should
be discussed along with the other listed alternatives.
-------
August 5, 1977
Page 6
Finally, the opening paragraph of this section indicates that
various alternatives are available to HRSD which would allow
them to attain their stated goal while eliminating many of the
adverse impacts of the present proposal. It might prove useful
to list these various options in tabular form for easy comparison.

SUBJECT: Relationship Between 201 Facility Planning and
Water Quality Management (WQM) Planning
FROM: Andrew W. Breidenbach, Assistant
for Water and Hazardous Material
/
TO: Regional Administrators PROGRAM GUIDANCE MEMORANDUM
Regions I - X Construction Grants No. 66
Water Quality Management SAM-1
PURPOSE
This policy statement describes the relationships between 201
facility planning and WQM planning under Section 208 and the minimum
facility planning requirements which an initial WQM plan must meet
for EPA approval of the WQM plan.
The purpose is to assure that facility plans can be completed and
processed expeditiously through EPA approval during those periods when
an initial WQM plan is either being prepared, approved, or implemented.
A second purpose is to have initial WQM plans prepared that satisfy,
at a minimum, certain requirements with respect to facility planning.
As WQM planning requirements overlap with the 201 planning requirements,
this policy seeks to minimize duplication and conflict between the two
planning efforts.
This policy statement supersedes the memo on the same subject
signed March 11, 1975, by James L. Agee (issued as construction grants
program guidance memo number 47 and planning guidance memo AM-1). Any
other policy or guidance statements contrary to this policy are also
superseded. This policy statement applies to all agencies (State and
local) responsible for either 201 or WQM planning.
BACKGROUND
201 Facility Planning
Facility planning consists of the plans and studies prerequisite
to the award of grant assistance for detailed design and construction
of publicly-owned treatment works. In the absence of a completed and
-------
- 2 -
approved WQM plan or approved interim outputs produced by the WQM
planning process, the facility plan must contain the following
elements:
1. Description of the planning area.
2. Selection of service areas.
3. Selection of overall treatment systems, including location,
capacity and configuration of all facilities, treatment
levels, and preliminary identification of type of treatment
and method of disposal of residual wastes.
4. Analysis supporting the selections in 2 and 3 based on
identification, evaluation and cost-effective comparison
of alternatives.
5. Preliminary designs and studies related to the selected
wastewater treatment systems, including sewer evaluation
surveys, surface and subsurface investigations of sites
for proposed facilities, preliminary designs and detailed
cost-effectiveness assessment, and other requirements set
forth in Section 35.917-1 of the Title II regulations.
WQM Planning under Section 208
WQM planning sets forth a comprehensive management program for
collection and treatment of wastes and controlling pollution from all
point and non-point sources. Control measures for abating pollution
from these sources utilize a combination of traditional structural
measures together with land-use or land management practices and regu-
latory programs. These measures are implemented by a management agency
or agencies designated in the plan. An initial WQM plan is developed
over a prescribed planning period and, thereafter, updated and approved
annually.
POLICY: RELATIONSHIP BETWEEN 201 FACILITY PLANNING AND WQM PLANNING
I. THE RELATIONSHIPS BETWEEN 201 AND WQM PLANNING IN THE SAME
GEOGRAPHIC AREA DURING THE PERIOD BEFORE FINAL EPA APPROVAL OF
A WQM PLAN ARE AS FOLLOWS:
A. 201 Planning
All 201 plans underway and on current or subsequent approved
priority lists should proceed expeditiously through to completion,
State certification and approval by EPA. The scope of 201 planning
approved before the final WQM work plan is approved by EPA should
be at a level necessary to complete all required elements of the
facility plan. The scope of 201 planning approved after the final
WQM work plan is approved by EPA should be at a level necessary to
-------
- 3 -
supplement work assigned to and within the capability of the respon-
sible WQM planning agency to accomplish expeditiously so that a
complete facility plan can be provided with minimal delay.
The WQM planning agency's review of ongoing facility plans
will generally be handled in accordance with procedures for the
A-95 review process.
B. Minimum Requirements for Facility Planning by WQM
Planning Agencies
During the initial planning period, WQM planning agencies
must produce the interim outputs specified in Program Guidance
Memorandum AM-2; generally, for designated areawide agencies,
these interim outputs will be completed within 9 months of the
date upon which the planning process becomes operational as
selected by the Regional Administrator. States conducting the
planning in non-designated areas may elect to place a lower
priority on facilities planning outputs, and, with the approval
of the Regional Administrator, may provide alternative schedules
to satisfy this interim output requirement.
For those municipal facilities within the WQM planning area
expected to receive a construction grant award during the five
years following initial WQM plan approval, the initial WQM plan
will include the facility planning information listed below. In
most cases, 201-funded facilities planning is either ongoing or
scheduled in the near term to support facilities construction over
the next several years. Thus, WQM planning agerjcies are expected
during this period to utilize and incorporate (not duplicate) the
201-funded planning information, supplementing the 201-funded or
programmed activities whenever deemed necessary by the Regional
Administrator.
Minimum requirements for facility planning to be summarized in
initial WQM plans for any facilities expected to receive a construc-
tion grant award during the five years following initial WQM plan
approval:
1. Selection of service areas
2. Preliminary estimate of municipal wastewater flows to be
generated during a 20 year planning period based on economic
and population projections for the WQM planning area.
3. Preliminary identification and comparison of the cost of
alternative treatment systems needed to handle projected
municipal wastewater flows, and to meet the requirements of
BPWTT or any more stringent discharge limitation necessitated
under the Act. Cost estimates may be based on streamlined
cost-estimating systems such as those prepared by Bechtel,
Black and Veatch, and ICARUS.
-------
- 4 -
4. Preliminary comparison of the cost of alternative general
configurations for needed wastewater collection at the
trunk line level.
5. Overall summary of environmental impacts of alternative
treatment and wastewater collection configurations.
6. Preliminary determinations, based on the above analysis,
of which municipal treatment systems and conveyance
configurations are likely to be most cost-effective.
7. Estimate of the land area required and possible financial
arrangements which could be utilized to construct these
facilities.
The terms "preliminary", "summary" and "estimate" in this
description are used to emphasize that the WQM plan will satisfy
these requirements by brief, general analysis and conclusions which
are much shorter and less detailed than those in a facility plan.
As such, these conclusions may be modified as a result of 201-funded
facility planning conducted in accordance with policies and procedures
described in Section II (see p. 5).
WQM planning agencies are also required to meet statutory require-
ments which are normally not considered a part of the facility planning
process but which, after approval of the WQM plan, will affect facility
planning. Such requirements include establishment of priorities and
time schedules for completion of treatment works, estimation of municipal
waste treatment system needs, identification of agencies necessary to
construct, operate and maintain treatment works,, and establishment of a
regulatory program that can affect facilities in the area (example -
stormwater or pretreatment controls).
C. Detailed Facility Planning in WQM planning Work Plans
New WQM planning work plans shall not be approved by the
Regional Administrator when they provide for detailed facility
planning beyond the minimum requirements in section B, above.
This detailed facility planning shall be handled by existing and
subsequent 201 facility planning grants.
Existing approved work plans for FY 74 and 75 designated 208
areawide agencies which provide for facility planning beyond the
minimum requirements should be amended to eliminate such detailed
planning, except where designated WQM planning agencies have already
contracted to conduct detailed facility planning and the contractor
has started the work and is too far along for the contract to be
revised or terminated as determined by the Regional Administrator.
If work plans are revised to eliminate detailed facility planning,
Section 201 planning grants should be quickly provided in these areas
in accordance with paragraph A above.
-------
- 5 -
D. Interim 208 Outputs
After interim outputs (AM-2) are approved by the State and
EPA for a WQM planning area, the relationship between 201 and WQM
planning in that area will be the same as described above except
that planning under any 201 grantvawarded after the approval of
the interim outputs must be consistent with these interim WQM
outputs. The scope and funding of new 201 planning should not
extend to developing a justification for the interim outputs,
as this will have been produced by the WQM planning process.
E. Coordination Between Concurrent 201 and WQM Planning
All WQM planning must be coordinated with facility planning
and other construction grant activity so that the final WQM plan
will facilitate needed construction in the area. Each State,
working with the Regional office must assure that effective coor-
dination between concurrent 201 and WQM planning does occur, and
that relationships between the two planning efforts are consistent
with this policy statement. The procedures for securing agreement
on relationships and responsibilities between concurrent 201 and
WQM planning efforts are at the discretion of the State. Conflicts
in approaches between concurrent 201 and WQM planning should be
resolved between the 201 and WQM planning agencies and concerned
State and local officials.
F. Transition to New WQM Requirements Affecting Facility
Planning
Any WQM plan which proposes a significant change in either
management or approach affecting construction grant awards must
allow adequate time and establish detailed procedures for transi-
tion to the new approach or management once the WQM plan is approved
by EPA.
II. THE FOLLOWING SPECIFIES THE RELATIONSHIPS BETWEEN 201 AND WQM
PLANNING AFTER THE WQM PLAN HAS BEEN COMPLETED, AND THE MANAGEMENT
AGENCY OR AGENCIES IDENTIFIED BY THE PLAN ARE APPROVED BY THE STATE
AND EPA.
A. Facility Plans Underway
All facility plans underway at the time of approval will be
completed by the agency which received the Step 1 grant. The
planning effort will continue expeditiously through to State
certification and EPA approval unless the approved WQM plan
clearly justifies a change in required treatment levels or alter-
native approach on the basis of substantially lower costs or major
changes in projected environmental impacts.
-------
- 6 -
B. New Facility Plans; Role of Designated Management
Agency(s)
New grants for 201 plans will be made to the management
agency(s) designated in the approved WQM plan. New facility
planning will be consistent with the approved WQM plan.
The scope and funding of new facility planning starts
should be sufficient to supplement the data and analysis in
the WQM plan to the extent necessary to provide a complete
facility plan as required by Section 35.917 of the Title II
regulations.
Where future 201 planning results in recommended projects
not in general conformance with the recommendations of an
approved WQM plan, review of the proposed change must be made
by the designated agency responsible for operating the continuing
WQM planning process. If the proposed change is accepted by the
WQM planning agency, the WQM plan is to be revised. (Revisions
will then proceed through the normal State certification and EPA
approval process.) If the proposed change is unacceptable, the
approved WQM plan is controlling.
Review of WOM Plans
Regional municipal construction grants personnel should review
sections of the work plans for WQM planning and draft WQM plans
focusing on facility planning elements to assure coordination between
WQM planning and the municipal facilities grant program consistent
with this guidance. State construction grants personnel should be
encouraged to do the same.

CONSTRUCTION GRANTS
Program Requirements Memorandum
NO. 77-8 THE ADMINISTRATOR
MEMORANDUM FOR Regional Administrators
SUBJECT: Funding of Sewage Collection System Projects
I. PURPOSE
This memorandum summarizes Agency policy on the award of grants for
sewage collection system projects under P.L. 92-500. It sets forth
guidance for rigorous review of grant applications to ensure that proposed
projects meet the established requirements of the law and regulations.
II. DISCUSSION
Sewage collection system projects may be grant eligible projects
under P.L. 92-500 (the Act) . Eligibility is limited, however, by Section
211 of the Act which provides for funding of collection systems only 1)
for the replacement or major rehabilitation of an existing collection
system or 2) for new collection systems in existing cormunities .
Sewage collection systems are defined in 40 CFR S 35.905-19 as:
For the purpose of S 35.925-13, each, and
all, of the common lateral sewers, within a
publicly-owned treatment system, which are
primarily installed to receive wastewaters
directly from facilities which convey wastewater
from individual structures or from private
property, and which include service connection
"Y" fittings designed for connection with those
facilities. The facilities which convey waste-
water from individual structures or from private
property to the public lateral sewer, or its
equivalent, are specifically excluded from the
definition, with the exception of pumping units,
and pressurized lines, for individual structures
or groups of structures when such units are cost
effective and are owned and maintained by the
grantee.
-------
The eligibility of sewage collection system projects is further
defined in 40 CFR § 35.925-13 which reads:
That, if the project is for, or includes
sewage collection system work, such work (a) is
for replacement or major rehabilitation of an
existing sewer system pursuant to § 35.927-3(a)
and is necessary to the total integrity and
performance of the waste treatment works
servicing such conntunity, or (b) is for a new
sewer system in a corcnunity in existence on
October 18, 1972, with sufficient existing or
planned capacity to adequately treat such collected
sewage. Replacement or major rehabilitation of
an existing sewer system may be approved only if
cost effective and must result in a sewer system
design capacity equivalent only to that of the
existing system plus a reasonable amount for
future growth. A camnunity, for purposes of
this section, would include any area with sub-
stantial human habitation on October 18, 1972.
No award may be made for a new sewer system in
a comtunity in existence on October 18, 1972
unless it is further determined by the Regional
Administrator that the bulk (generally two-thirds)
of the flow design capacity through the sewer
system will be for waste waters originating from
the cotinunity (habitation) in existence on
October 18, 1972.
This section of the EPA regulations implements Section 211 of
P.L. 92-500.
All treatment works funded under the construction grants program
must represent the most cost effective alternative to comply with the
requirements of the Act. Treatment works are defined in Section 212 to
include sewage collection systems. EPA cost-effectiveness requirements
are found in 40 CFR S 35.925-7 and in Appendix A to 40 CFR Part 35.
A large number of new collection system projects have appeared on
FY 1977 State project priority lists. The lists contain both individual
collection system projects and collection systems associated with treat-
ment plant and interceptor sewer projects. Many of these projects may
not meet the eligibility and cost-effectiveness requirements set forth
above.
Funding must be denied for all collection system projects which are
not grant eligible or not cost-effective. This is important for two
reasons. First, the requirements of the regulations must be satisfied.
Secondly, the funding of collection system projects not meeting the
-------
eligibility and cost-effectiveness requirements will commit limited
Federal dollars to projects which provide fewer pollution control benefits
than more needed treatment plants and interceptors.
Public disclosure of costs is a fundamental prerequisite for all
grants projects, including collection systems. Program Requirements
Memorandum 76-3, "Presentation of Local Government Costs of Wastewater
Treatment Works in Facility Plans," August 16, 1976, requires that cost
information be presented at all public hearings held on facility plans
after January 2, 1977. However, public hearings were held on many
collection system projects prior to this date. Special measures are
necessary to ensure the public is aware of the cost implications of
collection systems prior to their approval.
The following policy is to be followed in reviewing future grant
applications for collection system projects. This policy supplements
all existing Agency regulations and policy statements. It does not levy
any fundamentally new requirements, but provides guidance for more
rigorous review of grant applications to ensure that proposed projects
meet the established requirements of the law and regulations. Compliance
with this policy will help to assure that only grant eligible and cost-
effective collection system projects are funded by EPA.
III. POLICY
EPA policy on the funding of sewage collection systems is as fpllows:
A. Substantial human habitation
New collector sewer projects are eligible for funding only in a
cannunity in existence on October 18, 1972, with sufficient existing or
planned capacity to treat adequately such collected sewage. The Title
II regulation states in Section 35.925-13 that a ccrtmunity would include
any area with substantial human habitation on October 18, 1972. The
bulk (generally two-thirds) of the flow design capacity through the
sewer system is to be for wastewaters originating from the habitation.
The Agency policy is that closely populated areas with average
densities of 1.7 persons per acre (one household for every two acres) or
more on October 18, 1972, shall be considered to meet the requirement
for "substantial human habitation". Population density should be evaluated
block by block or, where typical city blocks do not exist, by areas of 5
acres or less. The "two-thirds" rule would apply within each area
evaluated when making a decision on collector sewer eligibility.
Densities of less than one household for every two acres rarely
result in serious localized pollution or public health problems from the
use of properly operated on-site systems. These areas should not be
considered to have had, on October 18, 1972, substantial habitation
warranting collection sewers from a pollution control standpoint.
-------
B. Cost-Effectiveness
New collector sewers must be proven in the facility plan to be
necessary and cost-effective in addition to being eligible under the
definition of "substantial human habitation" and the two-thirds rule.
New collector sewers should be funded only when the systems in use
(e.g. septic tanks or raw discharges from homes) for disposal of wastes
from the existing population are creating a public health problem, con-
taminating groundwater, or violating the point source discharge require-
ments of the Act. Specific documentation of the nature and extent of
health, groundwater and discharge problems must be provided in the
facility plan. Where site characteristics are considered to restrict
the use of on-site systems, such characteristics, (e.g. groundwater
levels, soil permeability, topography, geology, etc.) must be documented
by soil maps, historical data and other pertinent information.
The facility plan must also document the nature, number and location
of existing disposal systems (e.g. septic tanks) which are malfunctioning.
A community survey of individual disposal systems is recommended for
this purpose, and is grant eligible.
In addition, the facility plan must demonstrate, where population
density is less than 10 persons per acre, that alternatives are clearly
less cost-effective than new gravity collector sewer construction and
centralized treatment. Such alternatives are cited in the previous
Administrator's memorandum of December 30, 1976, subject: "Encouraging
Less Costly Wastewater Facilities for Small Communities" and Mr. Rhett's
memorandum of August 18, 1976 on "Eligibility of Septic Tanks and other
Small Treatment Systems". A draft guidance document accompanied the
August 18 memorandum. The draft policy represents the policy of the
Agency until issued in final form.
The alternatives to be evaluated include the following:
- measures to improve operation and maintenance of existing septic
tanks including more frequent inspections, timely pumpouts, and
prohibition of garbage grinders.
- new septic tanks
- holding tanks and "honey wagons"
- various means of upgrading septic tanks, including mounds,
alternate leaching fields and pressure sewers
- other systems to serve individual households or a cluster
of households. Such systems include, for example, wastewater
separation, water conservation and recycle systems where feasible.
-------
"Okie facility plan, where applicable, must examine alternatives such
as limited sewer service for a portion of a community. For example,
septic systems work very well in many small towns except in one isolated
area such as a business district where open space for adequate on-site
disposal is not available.
C. Public Disclosure of Costs
All projects, including collection systems, on which public hearings
were held after January 2, 1977, must comply fully with the requirements
of Program Requirements Memorandum 76-3 prior to approval.
Agency policy is to ensure public disclosure of the costs of any
collection system projects where a public hearing was held on or before
January 2, 1977. Such disclosure shall take the form of a prominently
published notice in a local newspaper, and the cost is grant eligible.
The Agency shall pay the cost of the notice if necessary to expedite the
project.
The notice shall include the estimated monthly charge for operation
and maintenance, the estimated monthly debt service charge, the estimated
connection charge and the total monthly charge to a typical residential
customer for the new collection system being funded and any other associated
wastewater facilities required. Such associated facilities would include
new treatment capacity needed to handle the flows from the new collection
system.
The charges may be only rough estimates, and may be presented as a
range of possible costs when major unknowns exist such as whether or not
substantial parts of the project are grant eligible.
IV. IMPLEMENTATION
The States are to be advised of the issuance of this policy at
once. All pending and future grant applications for collection system
projects or projects containing collection systems are to be reviewed
for compliance with this policy.
The requirements of sections III-A and III-C are effective immediately.
The requirements of Section III-B are effective immediately for all
projects which have received a step 1 facility planning grant but have
not yet received approval of their facility plan.
For all other projects, the requirements of section III-B are
effective immediately unless the Regional Administrator determines, from
information in the facility plan and other sources, that a project is
necessary and cost-effective even though the full documentation required
by section III-B is not available. In any case, the full requirements
of section III-B shall apply without exception to all projects being
reviewed for funding after September 30, 1977.
