Subject: Issuance of NPDES Permit NCO061638
Amherst WWTP
Wake County
Dear Mr. Highley:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as
subsequently amended).
This facility's discharge is one of four discharges within a 1.5 mile radius, all discharging into Middle
Creek or a tributary to Middle Creek:
NCO061638 Amherst Subdivision
NCO066150 Brighton Forest
NCO062715 Crooked Creek Subdivision
• NCO035181 NC Center for Mature Adults
The Permittees for the facilities listed above are hereby required to submit an Engineering Alternatives
Analysis (EAA). The EAA must evaluate the feasibility of pooling resources to bear the cost of sewer
line extension, with the goal of eliminating these discharges. If sewer line extension is economically
prohibitive, the EAA should evaluate the feasibility of managing the wastewater from all four sites
through one of the existing treatment facilities.
The Division will coordinate this process with the referenced Permittees. Contact Shannon Langley of
the NC DENR Raleigh Regional Office (919 571-4700) or Mike Templeton of the NPDES Unit (919
733-5083, extension 541) to arrange a meeting. The completed EAA must be submitted to the Division no
later than January 1, 2005.
This facility discharges in the Neuse River Basin (NRB). All streams in the NRB have been designated
as nutrient sensitive waters (NSW) as a result of algal bloom problems in the estuary. The North Carolina
Environmental Management Commission recently adopted rules establishing the Neuse River Basin
Nutrient Sensitive Waters Management Strategy for the reduction of phosphorus and nitrogen inputs. The
point source rule (15A NCAC 2B.0234) is intended to reduce total nitrogen (TN) discharges by 30% by
2003. It specifies that individually permitted wastewater discharges to the NRB with permitted flows less
than 0.5 MGD in 1995 shall be allocated a collective annual mass TN load of 155,400 pounds/year. This
is equivalent to an allocation in the range of 5 - 10 mg/L TN for each small facility. Although no TN
limit appears in this permit, your facility may be subject to nitrogen limits in the next permitting cycle.
The Division recommends that you evaluate the cost of installation for nutrient removal facilities in the
event that a nutrient limit is imposed on your plant. It is also recommended that alternative discharge
options be evaluated such as such as spray irrigation, subsurface systems, wastewater reuse, or connection

to a larger regional system.
The Division recommends that you consider ultraviolet (UV) disinfection for your facility. Chlorine can
be acutely toxic to aquatic organisms and forms secondary compounds that can also be detrimental to
aquatic life. UV disinfection would reduce the chemical load in your facility's effluent and reduce risks to
aquatic life instream.
As stated in the draft permit, the total residual chlorine limit will be instituted 18 month after the effective
date of the permit, June 1, 2005.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable
to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days
following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is
made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, the Coastal Area Management Act or any other Federal or
Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Sergei Chernikov at telephone number
[phone], extension 594.

year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the
discharge monitoring report for that month and shall report each year's annual results
(pounds/year) in the December report for that year.
A. (4) ANNUAL LIMITS FOR TOTAL NITROGEN
(a) TN limits for NPDES dischargers in the Neuse River basin are as prescribed in the basin's
Nutrient Management Strategy rule for wastewater treatment facilities, T15A NCAC 2B
.0234.
(b) The Permittee's TN discharge is governed by this Permit unless the Permittee is a member
and co-permittee of an approved compliance association, in which case its TN discharge is
governed by the association's group NPDES permit and the limits therein.
(c) TN limits for NPDES dischargers in the Neuse River basin are annual, calendar -year limits.
All such limits in effect on January 1 of a given year remain in effect for the entire calendar
year. Changes in TN limits become effective on January 1 of the year following permit
modification and remain in effect for the full year. Similarly, changes in membership in a
compliance association become effective on January 1 of the year following the change and
remain in effect for the full year.
(d) For any given calendar year, the Permittee shall be in compliance with the annual TN Load
limit in this Permit if:
(1) the Permittee's annual TN Load is less than or equal to said limit, or
(2) the Permittee is a Member of a compliance association and a Co-Permittee to the association's
group NPDES permit.
(e) The Permittee's effective TN limit (if any) may change due to changes in its TN allocation or
membership changes in a compliance association.
(1) The Permittee may notify the Division and request a modification of this Permit to incorporate
allowable changes in its TN Load limit. Allowable changes include those resulting from purchase
of TN allocation from the Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation
between the Permittee and other dischargers; regionalization; and other transactions approved
by the Division.
(2) If the Permittee intends to join or leave a compliance association, the Division must be notified of
the proposed change.
(3) Upon receipt of timely and proper notification, the Division will modify the affected permit(s) as
necessary to incorporate the allowable changes in TN limits or to reflect the change in
membership.
a. The Division must receive notification no later than August 31 for changes proposed for the
following calendar year.
b. Notification shall be sent to:
NC DENR / DWQ / NPDES Unit
Attn: Neuse River Basin Coordinator

MEMORANDUM
TO: Christie Jackson, NPDES Unit

FROM: _r"i L. Bryant, Piedmont Region Coordinator
Habitat Conservation Program
DATE: 22 September 2003
SUBJECT: Proposed Permit Renewal for Amherst WWTP, Wake County, NPDES Permit No.
NC0061638.
Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject
application for impacts to fish and wildlife. Our comments are provided in accordance with provisions of
the Clean Water Act of 1977 (as amended), the Fish and Wildlife Coordination Act (48 Stat. 401, as
amended; 16 U.S.C. 661-667d), and North Carolina General Statutes (G.S. 113-131 et seq.).
Nero Utilities, Inc., Amherst WWTP, has submitted a request for a permit renewal to discharge
treated wastewater into Middle Creek in the Neuse River basin. It appears that this plant may utilize
chlorine in their treatment system. Chlorine is acutely toxic to aquatic organisms and forms secondary
compounds that are also detrimental to aquatic life. In addition, the dechlorination agent, hydrogen
disulfide, is also very toxic to aquatic life. We are especially concerned with impacts of this project on
the sensitive species that are found in this system. We have records for the existence of several federal
and state endangered mussels, including the federal endangered dwarf wedge mussel (Alasmidonta
heterodon) in Middle Creek.
We recommend that the following conditions be incorporated into the permit to reduce impacts to
fish and wildlife resources and in particular to listed species.
We request that ozone or ultraviolet light systems replace the chlorine systems. These
disinfectants also provide an additional benefit of removing a hazardous material from the
workplace.
2. If not already in place, we suggest the installation of a stand-by power system.
Thank you for the opportunity to provide input on this permit renewal. If we can be of further
assistance, please contact our office at [phone].

PART IV - EVALUATION AND RECOMMENDATIONS
Nero Utilities was purchased by Utilities, Inc. (CWS) in 2000. Since that time the
facility has undergone many improvements. The last compliance inspection revealed that the
facility is well operated and maintained. There is no TRC limit on the current permit,
however the operator has dechlorination equipment and removes 90% of the initial TRC
before discharge. The staff of the RRO recommends that the permit be renewed in
accordance with the basin wide plan.
