Arcadis Geraghty & Miller Project No. NC039477.0005
Dear Ms. Swank:
Our frrm has been retained by the City of Goldsboro to assist in planning for an
upgrade and expansion to the City's wastewater treatment plant (WWTP). The plant
currently operates under NPDES Permit No. NC0023949. The permit was last
renewed an February 1, 1994 and expires on January 31, 1999, The WWTP is
currently permitted to discharge 10.1 MGD to the Neuse River.
As part of our planning and development of a 201 Facilities plan, we would appreciate
receiving an opinion regarding effluent limits that may be imposed on the Goldsboro
WWTP for the proposed expansion. We request that speculative limits be provided
for two permitted flow conditions: 13.5 MGD and 16.9 MGD.
We recognize that the limits developed for this request by the Modelin /T'MDL Unit
will be speculative in nature. We would appreciate as prompt a response as possible
so that we may proceed with our planning. Please don't hesitate to call me at 782-
5511 x-164 if you should have any questions or need more information.
Sincerely,

FROM: Coleen Sullir(,�,H,. l
SUBJECT: Goldsboro's Wastewater Treatment Plant Expansion
NPDES Permit # NC0023949, Wayne County
Michelle Suverkrubbe
I have reviewed the scoping letter submitted by the City of Goldsboro for a proposed expansion of their
wastewater treatment plant to 16.9 MGD. I have also reviewed Ruth Swanek's comments on the nitrogen
and oxygen -consuming waste strategies that apply in the Neuse River. In addition to these comments,
Goldsboro needs to be aware that any proposed expansion of a wastewater treatment facility requires an
engineering alternatives analysis of the options available to dispose of the wastewater. The alternatives
analysis must discuss the feasibility of handling some or all of the expansion volume through a
nondischarge alternative (spray irrigation or reuse) and contain a present worth cost analysis of the
different options. Such an evaluation must also include a justification and demonstration of the need for
the increased volume, including any flow reductions that can be realized through reduction of infiltration
and inflow to the existing system and use of water conservation measures. Finally, the Environmental
Assessment should discuss the impact on water quality from the change in land use that may occur as a
result of the expansion and measures proposed to be taken to mitigate such impacts.
If you have any questions concerning the above comments, please call me at extension 550.

MEMORANDUM
TO: Michelle Suverkrubbe
THROUGH: Don S
FROM: Ruth Swanek 2E5
SUBJECT: Goldsboro Scoping Letter Comments
I have reviewed the-scoping letter submitted by the City of Goldsboro fora proposed expansion of
its WWTP to 16.9 MGD. The City should be informed of strategies to control nitrogen and
oxygen -consuming waste in the Neuse River. I have briefly outlined these strategies below:
The lower Neuse River Basin is experiencing eutrophication problems, .and the Division of Water
Quality (DWQ) is developing a strategy to control the nutrient loading to the estuary from point and
nonpoint sources. DWQ drafted rules to reduce nutrient loading in the basin, and these rules were
publicly noticed and sent to public hearing. DWQ is currently revising this draft nutrient sensitive
waters (NSW) strategy based on comments we received during the public comment period. Based
on these comments, we are reviewing the possihility of including mass based nitrogen limits in the
NPDES permits instead of the concentration limits currently proposed. Annual nitrogen loading
Limits based on an effluent total nitrogen concentration of 3-4 mg/land 1995 permitted flow may he
included in the final strategy. For example, a 10 MGD facility would receive annual TN loading
limits based on the following equation:
TN load limit (lb/yr) _ (10 MGD)*(3.5 mg/1 TN)*(8.34)*(365) = 106,500 lb/yr
This annual Ioad limit would be assigned in lieu hf the monthly average TN limit of 6 mg/I
proposed in the current draft rules. Since these lower concentrations will be used to assign limits
in terms of annual load and not monthly concentration limits, we do not expect that major
cliffi'.rences in facility design would result from changing the current draft rules to annual loading
requirements. Although a final strategy is not yet available, Goldsboro should plan on installing
state-of-the-art nitrogen removal at its facility in order to meet the requirements of any finalized
rules.
The General Assembly is also examining the possihility of requiring dischargers in NSW waters to
install hest available nitrogen removal technology. Goldsboro may wish to review any proposed
legislation that would impact point sources.
Finally, the 1993 "Neuse River Basinwide Water Quality Management Plan" outlines a strategy for
oxygen consuming wastes on the Neuse tnainstem. A water quality model for the mainstem
predicted that dissolved oxygen violations would occur if facilities discharged at their permitted
levels. In order to protect the river, it is recommended that all new and expanding dischargers
receive BOD and ammonia limits of 5 mg/I and 2 mg/1 respectively.
If you have any questions, please call me at extension 503.

RE: Environmental Assessment for Wastewater Treatment Plant Expansion
City of Goldsboro, NC
Dear Mrs. Baggett:
The City of Goldsboro is initiating a State Environmental Assessment for the proposed project
which includes an expansion of the existing wastewater treatment plant to provide capacity
for growth and improvements. to the plant to increase nutrient removal. We are requesting
a state project review number and agency scoping comments. The project location is shown
on the attached map.
The existing wastewater treatment plant is currently permitted to discharge 10.1 MGD into
the Neuse River. The proposed project will expand the plant to 16.9 MGD. The expansion
will allow Goldsboro's wastewater treatment plant to serve as a regional facility as well as
accommodating Goldsboro's growth. The City has recently received requests from the nearby
Towns of Fremont and Pikeville and from Wayne County to accept wastewater, thus allowing
those small facilities with documented treatment problems to be removed from service. It is
anticipated that Goldsboro will continue to receive similar requests to provide wastewater
treatment services for other communities in the region. The proposed project will also allow
the plant to meet the proposed State regulations for nutrients in effluent discharges to the
Neuse River.
The proposed project includes sludge dewatering facilities to be located on the site of the
existing wastewater treatment plant. The City will use the dewatered sludge for composting
with yard waste to produce a beneficial product. The composting facility will be addressed
in a separate Environmental Assessment.

The City of Kinston is proposing to install a WS intake on the Neuse mainstem in the vicinity of
Pot Neck. This WS intake will serve the City of Kinston's growth as well as provide water for the
Global TransPark. A withdrawal of up to 24 MGD is proposed. There are several notes about this
project as well as a letter to the City of Kinston outlining our concerns in the basin files in Juan's
