average total phosphorus NPDES permit limits. The proposed upgrade
will also expand the sludge thickening and aerobic sludge
stabilization/storage facilities. The proposed project will not include an
increase in design capacity.
mitigative measures are implemented, and an environmental impact statement will not be
required. The decision was based on information in the 201 Facilities Plan Amendment and
reviews by governmental agencies. An environmental assessment supporting this action is
attached. This FNSI completes the environmental review record, which is available for
inspection at the State Clearinghouse.
Article I, Chapter 113A of the North Carolina General Statutes requires an action to be subject to
the requirements of the North Carolina Environmental Policy Act (NCEPA) if it involves the
expenditure of public funds and a potential impact is anticipated to the environment. The project
has been evaluated for compliance with the NCEPA and determined to be a major agency action
which will affect the environment.

ENVIRONMENTAL ASSESSMENT
A. Proposed Facilities and Actions
Figure 1 identifies the location of the proposed wastewater treatment facilities.
B. Existing Environment
New Treatment Facilities. The town of Clayton proposes to upgrade its Little Creek Water
Reclamation Facility (LCWRF) at the existing flow capacity of 2.5 million gallons per day
(MGD). To meet more stringent NPDES permit limits and expand the sludge thickening and
aerobic sludge stabilization/storage facilities, the Clayton LCWRF requires new anaerobic tanks
and new denitrification filters for nutrient removal. A methanol feed system will be constructed
to augment the treatment by the filters. There will be an upgrade of the aeration systems in the
existing oxidation ditches, and the oxidation ditches will be modified to include first stage anoxic
tanks and denitrification gates for use as a denitrification system. The existing alum and polymer
feed systems will be used for either polishing chemical phosphorus removal or improved
clarification, when necessary. The existing magnesium hydroxide or liquid sodium hydroxide
feed systems will be used for pH and alkalinity control, when necessary, for improved
phosphorus removal and nitrification. The existing traveling bridge filters will be used for
additional treatment when necessary, for instance during a high flow event. This alternative will
also expand the sludge thickening and aerobic sludge stabilization/storage facilities.
Surface Water. The two major surface waters in the Clayton service area are Little Creek and
the Neuse River. Little Creek flows through the Clayton service area from the northwest to the
south and is a tributary to Swift Creek, which flows into Middle Creek immediately before
Middle Creek’s confluence with the Neuse River to the southwest of the Clayton service area.
Little Creek is classified as a nutrient sensitive (C-NSW) water. In the Clayton service area,
Little Creek is currently impaired because of a “Fair” bioclassification at one of its ambient
monitoring sites. Ambient monitoring of Swift Creek at sites downstream of the Clayton service
Topography and Soils. The project area lies within the transition zone between the Piedmont
and Coastal Plain physiographic provinces. Elevations within the town of Clayton range from
130 feet to 330 feet above sea level. Most of the area has gently rolling to steep topography and
depositional areas along streams are flat. Natural surface drainage is generally medium to rapid,
and drainage tends toward the northeast and south. The Clayton service area is primarily
composed of the Appling-Cecil Association and Norfolk-Wagram Association of soils. The
Appling-Cecil Association soils are derived from gneiss and schist and are deep and well-
drained. They have moderate permeability and susceptibility to erosion. The Norfolk-Wagram
Association of soils are derived from coastal sedimentation. These soils are deep and well-
drained to excessively well-drained. They have rapid to very rapid permeability and slight to
moderate susceptibility to erosion.

C. Existing Wastewater Facilities
D. Need for Proposed Facilities and Actions
The town of Clayton has recently expanded its LCWRF from 1.9 MGD to 2.5 MGD. As per its
NPDES permit, the town will be required to comply with an annual limit for total nitrogen of
21,400 pounds/year. Because the 2.5 MGD expanded plant was not designed to comply with this
annual limit for total nitrogen, Clayton has become a member of a group compliance association
(Neuse River Compliance Association) and a co-permitee of the association’s group NPDES
permit. The proposed upgrade will also allow the Clayton LCWRF to comply with the quarterly
average total phosphorus limit of 2.0 mg/L by coverage under the association’s group permit,
instead of having to comply with the more stringent monthly average total phosphorus limit of
1 mg/L, which would be required if the facility was not a member of a group compliance
association. Although the town of Clayton has selected the option of complying with the annual
limit for total nitrogen and quarterly average total phosphorus limit of 2.0 mg/L by joining the
Neuse River Compliance Association, it is the town’s intention to provide such total nitrogen and
total phosphorus facilities at the plant to meet an annual total individual nitrogen limit of 21,400
pounds/year and a quarterly average total phosphorus limit of 2.0 mg/L. The biological nutrient
The town of Clayton operates the 2.5 MGD LCWRF, which discharges its effluent to Neuse
River. The treatment facility consists of a mechanically cleaned bar screen, a manually cleaned
bar screen, vortex type grit removal system, 9-inch Parshall flume for influent flow metering,
influent wastewater pumping, extended aeration Carrousel type oxidation ditches, secondary
clarifiers, sludge recirculation/waste pumping, magnesium hydroxide feed system for pH and
alkalinity controls, alum feed system for chemical phosphorus removal, polymer feed system for
enhanced clarification, tertiary shallow bed traveling bridge filters, UV disinfection,
chlorination/dechlorination facilities (back-up only), effluent pumping to the Neuse River,
aerobic sludge digestion tank, polymer sludge conditioning and thickening by drum thickener,
sludge storage tank, sludge drying beds, and sludge loading station for sludge disposal by land
application. The wastewater collection and outfall system consists of sewer pipe ranging in size
from 6 to 18 inches in diameter and eight pump stations.
Water Supply. The town of Clayton receives its potable water from the Johnston County water
plant, which takes its water from the Neuse River. There are residences within the Little Creek
WRF service area that rely on wells for their potable water supply. The groundwater table is
generally 10-15 feet from the surface, and most wells are drilled to depths of 100-200 feet.
Groundwater supplies are generally adequate and of a good quality.
area does not indicate any water quality impairment. The Clayton wastewater treatment plant
discharges its effluent to the Neuse River, which is classified as a nutrient sensitive water supply
(WS-IV-NSW). The Clayton service area lies within the 03-04-02 subbasin of the Neuse River.
Benthic microinvertebrate community samples from this subbasin are rated “Good.” Fish
consumption use support rating for subbasin 03-04-02 indicated that all waters within the
subbasin are impaired for this use support category.
E. Alternatives Analysis
The option of optimizing operation of the existing facilities was considered. Evaluation of the
overall treatment plant and unit processes indicates that the plant is currently operating at
optimum efficiency and is in compliance with the effluent limitations given in its NPDES permit.
The July 2002 rerating of the plant to 2.5 MGD did not include an upgrade of its nutrient
removal facilities. Although the town of Clayton has selected the option of complying with the
annual limit for total nitrogen and quarterly average total phosphorus limit of 2.0 mg/L by
joining the Neuse River Compliance Association, it is the town’s intention to provide adequate
total nitrogen and total phosphorus facilities at the plant to meet an annual total individual
nitrogen limit of 21,400 pounds/year and a quarterly average total phosphorus limit of 2.0 mg/L.
Because the current nutrient removal facilities at the Clayton LCWRF will not provide adequate
nutrient removal at its cunent permitted flow of 2.5 MGD, the option of optimally operating the
existing facilities was rejected.
A facilities plan was prepared, and six options were evaluated: 1) no action; 2) optimum
operation of existing facilities; 3) wastewater reuse; 4) relocation of the effluent discharge;
5) a regional treatment facility; and 6) upgrading the existing facility.
The alternative of relocating the effluent discharge point of the Clayton LCWRF from the
nutrient sensitive waters of the Neuse River to the Cape Fear River Basin was evaluated. This
alternative would require the installation of approximately 27 miles of force main and several
booster pump stations. The permitting issues and construction costs associated with transporting
the Clayton LCWRF effluent to the Cape Fear River Basin would raise several issues and
concerns. One primary issue would be the interbasin transfer of water from the Neuse River
Basin to the Cape Fear River Basin. Considering the construction cost, permitting issues, and
environmental concerns associated with relocating the discharge of the Clayton LCWRF to the
Cape Fear River Basin, this alternative was removed from further consideration.
removal processes at the Clayton LCWRF must be upgraded to allow the town to achieve
enhanced nutrient removal at its current permitted flow of 2.5 MGD.
The “No Action” alternative will result in the town of Clayton not taking any action to comply
with more stringent nutrient removal requirements and EPA 503 and NCDWQ sludge
regulations on sludge stabilization and disposal. The “No Action” alternative would cause the
plant to continue to discharge increased nutrient loadings to the Neuse River, resulting in adverse
impacts on the aquatic habitat downstream of the discharge. The “No Action” alternative was
rejected.
The alternative of employing wastewater reuse for a portion of the LCWRF effluent was
explored. The town of Clayton is currently engaged in a reuse project involving the use of some
of the LCWRF effluent at the Pine Hollow golf course for irrigation. Plans and specifications
are being prepared for this project. It is anticipated that this project will reduce an average of
175,000 gallons per day (GPD) of direct discharge to the Neuse River.
T
F. Environmental Consequences, Mitigative Measures
The proposed Clayton LCWRF upgrades will be located within the property limits of the existing
plant site on previously disturbed land. Therefore, no change in land use is required. There are
no sewer line extensions associated with this project. The proposed project will not include an
increase in design capacity for the water reclamation facility. Because no wetlands have been
observed or delineated within the project area, the proposed facility will not have any direct
impacts on wetlands. The project will not disturb prime or unique agricultural lands since the
existing treatment plant site is located on previously disturbed land. There will be no indirect or
Two options were considered in creating a regional wastewater treatment facility to provide a
solution to Clayton s wastewater treatment and disposal needs: 1) the discharge of Clayton’s
wastewater to the city of Raleigh’s wastewater treatment and collection system, and 2) the
discharge of Clayton’s wastewater to the Johnston County wastewater treatment and collection
system. A request was made to the city of Raleigh for accepting up to 2.5 MGD of Clayton’s
wastewater flow and providing cost of sewer service to the town of Clayton. In response to the
request, Raleigh informed Clayton that it is not considering any additional requests for contract
wastewater treatment capacity sales at this time and, therefore, no capacity is available to the
town of Clayton. The town of Clayton already has an agreement to purchase 250,000 GPD
capacity from the Johnston County Regional Wastewater Treatment plant. This agreement will
not provide adequate capacity to provide all of Clayton’s wastewater treatment and disposal
needs. The option of creating a regional wastewater treatment facility was rejected.
Three alternatives were also considered for modifying or upgrading the existing facilities. Land
application of a portion or all of the 2.5 MGD flow from the LCWRF was considered. However,
due to the difficulty of acquiring an adequate land parcel for land application of wastewater and
the cost of such a project, the alternative of land application was eliminated from further
consideration. An alternative for upgrading the existing facilities that would involve continuing
discharge to the Neuse River was rejected because it will not achieve the desired effluent quality
in a cost-effective manner. The third alternative considered for upgrading the existing facilities
also involves continuing discharge to the Neuse River. To meet more stringent NPDES permit
limits and expand the sludge thickening and aerobic sludge stabilization/storage facilities, the
Clayton LCWRF requires new anaerobic tanks and new denitrification filters for nutrient
removal. A methanol feed system will be constructed to augment the treatment by the filters.
There will be an upgrade of the aeration systems in the existing oxidation ditches, and the
oxidation ditches will be modified to include first stage anoxic tanks and denitrification gates for
use as a denitrification system. The existing alum and polymer feed systems will be used for
either polishing chemical phosphorus removal or improved clarification, when necessary. The
existing magnesium hydroxide or liquid sodium hydroxide feed systems will be used for pH and
alkalinity control, when necessary, for improved phosphorus removal and nitrification. The
existing traveling bridge filters will be used for additional treatment when necessary, for instance
during a high flow event. This alternative will also expand the sludge thickening and aerobic
sludge stabilization/storage facilities. This option will not require an increase in permitted
capacity. This third alternative is the preferred plan and it is the selected alternative because it is
the most cost-effective option.
cumulative effects of the proposed project on prime agricultural lands because there are no
unique agricultural lands within Clayton and its extraterritorial jurisdiction. Because
construction of the proposed wastewater treatment facilities will take place at the existing cleared
plant site, there will be no direct impacts to forest resources. Since the proposed facilities are
located on existing treatment plant property, no public lands or scenic and recreational areas will
be affected by this project. Upgrading the nutrient removal facilities at the Clayton LCWRF will
reduce nutrient loading to the Neuse River. This will improve the water quality for canoeing,
fishing, and other water-related activities, thereby increasing the scenic and recreational value
provided by the Neuse River. No areas of archaeological or historical value will be directly
impacted by the proposed project, because such sites have not been identified along or near the
construction areas of the proposed project. Construction activities associated with the proposed
project will result in minor noise and air quality impacts from construction equipment and
material delivery. These impacts will be localized and of short duration. Noise levels may
increase during construction of the proposed facilities, but their impact will be minimized by
limiting construction to daylight hours only and using muffler systems on all machinery. Direct
impacts to groundwater quality are expected to be minimal. The proposed project will cause a
minimal increase in impermeable surface coverage at the Clayton LCWRF, but this should not
affect groundwater recharge rates. The upgrading of the biological nutrient removal facilities at
the treatment facility will have a beneficial effect on downstream surface waters because of
reduced nitrogen and phosphorus loadings to the Neuse River. Construction of the proposed
project will not impact Clayton’s drinking water supply. Because construction of the proposed
facilities will happen on a previously disturbed site, the proposed facilities will not have a
negative impact on wildlife. There could be negative effects on the soil and water in the project
area due to erosion at the construction site. This erosion could impair the aquatic habitat by
increasing turbidity in streams, which may adversely affect aquatic species, including aquatic
flora, fish and shellfish. However, contractors will be required to prepare and implement an
erosion and sedimentation control plan prior to construction to mitigate the damage to aquatic
resources. Also, during construction of the project, on-site inspections will be provided to ensure
that the best management practices are being employed to reduce the impact of the project on
surface waters. Because the construction area for the proposed facilities will be constructed
within the existing Clayton LCWRF boundaries in a previously disturbed area, there will be no
significant disturbance of natural plant communities. The proposed project will not have an
effect on rare plant species, as none of these species are known to exist in the Clayton service
area. The proposed project will not have an impact on forest resources because no woodland
will be cleared for this project. The North Carolina Division of Water Quality, NPDES Unit
concurs with the proposed project. The North Carolina Wildlife Resource Commission concurs
with the proposed project. The North Carolina Division of Parks and Recreation concurs with
the proposed project. According to the U.S. Fish and Wildlife Service, there are no threatened or
endangered species known to inhabit this previously disturbed site. The North Carolina
Department of Cultural Resources is not aware of any properties of architectural, historical, or
archaeological significance that would be affected by the project. The Raleigh Regional Office
concurs with the project. Other state agencies did not submit objections to this project.

A public hearing was held on Monday, July 21, 2003 on the proposed project. No objections
were expressed about the project. The proposed project will require the town of Clayton to
increase its rates for sewer service. The increased user charge for a customer using 5,000 gallons
per month will be $11.60 per month, compared to a current user charge of $6.80 per month.

Please contact me at [phone] x260 or mailto:paul.clark(q)ncmail.net if you have any
questions or comments. Thanks.
Following the site visit on December 2, 2003 with Charles Davis (The Wooten Company) and James
Warren (ORC) comments can be summarized as follows:
Wastewater Flow: After leaving the headworks, wastewater will enter two of the three proposed
anaerobic basins. Wastewater will enter the third proposed anaerobic basin via an opening in the wall
between the second and third basins. Wastewater will exit the third basin to the existing splitter box.
From the splitter box, wastewater will go to the proposed anoxic basins. Each anoxic basin will be
connected to the existing aeration basin adjacent to it to allow controlled flow between the basins and
flow recycling. Wastewater exits both aeration basins to an effluent box with weir gate. Wastewater then
goes to another splitter box that divides flow between the three clarifiers. After clarification, wastewater
will go to the new denitrification filters, then to the UV disinfection and finally to discharge.
The construction sequence for proposed project intends to minimize the amount of time that the facility
will have to utilize only one aeration basin.
James Warren was given the Notice of Intent (NOI) application form for the NPDES General Permit for
Wastewater Treatment Works NCG110000. Division of Water Quality Stormwater contacts were also
provided to Mr. Warren.
Sludge Flow: Sludge leaving clarifiers goes to the return sludge pump station where it will be pumped to
either of the following: (a) new anaerobic basins, (b) new anoxic basins (connected to aeration basins) or
(c) new sludge thickener building and then to new sludge stabilization/holding tanks.
Construction of the majority of the proposed project will occur within the existing fenced area. There will
be an access road constructed immediately outside the existing fence and the fence will be relocated in
this area. This road construction should not impact any waters or wetland areas. All construction activity
should occur 50 feet or more from jurisdictional waters and wetlands to abide by Neuse buffer
requirements. If this is not possible, a waiver or permit must be secured.

Dear Mayor McCormac:
1633 Mail Service Center Raleigh, NC 27699-1633Construction Grants & Loans Section
Web Site www.nccql.net
The Construction Grants and Loans Section sent you a letter on May 21, 2003 regarding
the effluent characteristics at the subject municipal wastewater treatment plant. To date we have
not received any response from you or your Engineer regarding this matter. We encourage you
to respond to us as soon as possible or provide a plan for how to address this matter.
The Honorable Douglas A. McCormac, Mayor

To briefly summarize the salient points of the letter sent to you, for land irrigation (non­
discharge permitted) systems, the evaluation of whether or not a municipal wastewater treatment
plant treats industrial wastewater is critical in order to comply with the one/three foot separation
rule, contained in NCAC 2H.0219(e):
■p
—i
“Waste shall not be applied or discharged onto or below the land surface when the
vertical separation between the waste and the seasonal high water table is less than one
foot. If the area is to be utilized for industrial waste and has a separation of less than
three feet, and in other areas as designated by the Director, a demonstration must be
made using predictive calculations or modeling methods, acceptable to the Director, that
such placement will not result in contravention of classified groundwater standards. ”
There are two options available to you for resolution of this matter: demonstrate that the
vertical separation from the land surface to the mounded seasonal high water table is three feet or
greater, or demonstrate that the treated effluent will not violate the groundwater standards at the
compliance boundary. This second option will require that the effluent be tested for a wide
range of conventional wastewater chemicals, in addition to metals and organics. For your
convenience we have included the chemical testing requirements in this letter.
Again, these comments have been written to address existing regulations associated with
the land application of municipal wastewater effluent. Our goal is to approve the plans and
specifications as soon as possible. A thorough and timely response is necessary in order to
accomplish this goal.
