Subject: Issuance of NPDES Permit NCO061492
Maury Sanitary Land District'vV`WTP
Greene County
Dear Mr. Move:
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 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. All facilities with permitted
flow greater than or equal to 0..5 MGD are receiving a TN limit in this permit 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.

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 (50) 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 Christie Jackson at telephone

Hi Charles:
I recommend that MSD be required to "declare" a final disposal for its sludge. It can be the old lagoon. However,
final disposal in the lagoon is complex per 503 rules. MSD is sliding -by now. I recommend a condition requiring MSD
to declare the final disposal method and apply for a permit(land application, lagoon disposal, etc.) within tweleve
months after the NPDES permit is issued.

PART IV - EVALUATION AND RECOMMENDATIONS
The facility is currently preparing an A to C for the additions outlined in
the proposed wastewater treatment facility section. McDavid and assoc. is the
Town's current engineering firm responsible for initiating the proper paper
work.
The Town is utilizing the old lagoon system as their sludge storage facility.
Currently there is no piping available to return water from the sludge lagoons
to the WWTP. In order for this to be permitted the Town should be required to
submit a management plan assuring that the hydraulic balance on the old
lagoons can be controlled in times of heavy moisture. The Town will likely
need to add another line coming from the lagoon system to the head of the
treatment works. The Town should be given 90 days from issuance of the permit
to submit a plan describing how they will use the old lagoon system as a
sludge storage facility.
It is recommended that the permit be reissued with the condition that the Town
submit a management plan to address the use of their lagoons as sludge
storage.
