ENVIRONMENTAL MANAGEMENT COMMISSION
COUNTY OF STANLY
IN THE MATTER OF
NORTH CAROLINA
NPDES PERMIT NO. NC0024244
PERMIT NO. WQCS00016
HELD BY
THE CITY OF ALBEMARLE
SPECIAL ORDER BY CONSENT
EMC SOC WQ S19-007 Ad I
Pursuant to provisions of North Carolina General Statute (G.S.) 143-215.2 and G.S. 143-215.67,
this amendment to a Special Order by Consent is entered into by the City of Albemarle,
hereinafter referred to as the City, and the North Carolina Environmental Management
Commission, an agency of the State of North Carolina created by G.S. 143B-282, and hereinafter
referred to as the Commission:
1. The City and the Commission hereby stipulate the following:
(a) The City holds North Carolina NPDES Permit NC0024244 for operation of an existing
wastewater treatment works and for making an outlet therefrom for the discharge of
treated wastewater to Long Creek, Class C waters of this State in the Yadkin -Pee Dee
River Basin. The City is unable to consistently comply with the final effluent limits,
including Biochemical Oxygen Demand (BOD), Ammonia Nitrogen, Total Suspended
Solids (TSS), and Fecal Coliform. The City is unable to comply with operational
requirements as set forth in NPDES Permit NC0024244 due to high levels of inflow and
infiltration entering the City's sewer lines, and the WWTP's inability to handle low
influent concentrations of BOD. The City also holds North Carolina Collection System
Permit WQCS00016 for operation of an existing wastewater collection system, but is
unable to consistently comply with permit Condition 1.2 regarding sanitary sewer
overflows (SSOs) as set forth in Collection System Permit WQCS00016. Compliance
will require preparation of plans and specifications for collection system upgrades
including, but not limited to, pump station upgrades/improvements and sewer line (force
main) rehabilitation to be conducted in three phases.
(b) Noncompliance with final effluent limitations constitutes, causing, and contributing to
pollution of the waters of this State named above, and the City is within the jurisdiction
of the Commission as set forth in G.S. Chapter 143, Article 21.
(c) The City has secured a grant or has otherwise secured financing for planning, design, and
construction/repairs of the following:
i. New or improved wastewater treatment and disposal system components as described
in Attachment B which, once constructed and operated, will be sufficient to
adequately convey and treat wastewater presently being discharged, to such an extent

City of Albemarle — Long Creek WWTP
EMC SOC WQ S19-007 Ad I
Page 2 of 6
that the City will be able to comply with the final effluent limits and operational
requirements as set forth in NPDES Permit NC0024244.
ii. A new or improved wastewater collection system which, once constructed and operated,
will be sufficient to adequately collect wastewater presently being made tributary to the
collection system, within the Sanitary Sewer Rehab Phase 1, Phase 2, and Phase 3 such
that the City will be able to comply with permit Condition 1.2 regarding sanitary sewer
overflows (SSOs) as set forth in Collection System Permit WQCS00016.
(d) Since this Special Order is by Consent, neither party will file a petition for a contested
case or for judicial review concerning its terms.
2. The City, desiring to comply with the Permits identified in paragraph 1(a) and 1(b) above,
hereby agrees to do the following:

4. The City and the Commission agree that the stipulated penalties are not due if the City
satisfies DWR that noncompliance was caused solely by:
a. An act of God;
b. An act of war;
c. An intentional act or omission of a third party, but this defense shall not be available if
the act or omission is that of an employee or agent of the defendant or if the act or
omission occurs in connection with a contractual relationship with the permittee;
d. An extraordinary event beyond the permittee's control. Contractor delays or failure to
obtain funding will not be considered as events beyond the permittee's control; or
e. Any combination of the above causes.
Failure within thirty (30) days of receipt of written demand to pay the penalties, or challenge
them by a contested case petition pursuant to G.S. 150B-23, will be grounds for a collection
action, which the Attorney General is hereby authorized to initiate. The only issue in such an
action will be whether the thirty (30) days has elapsed.
5. Noncompliance with the terms of this Special Order by Consent is subject to enforcement
action in addition to the above stipulations, including injunctive relief pursuant to G.S. 143-
215.6.C.
6. This Special Order by Consent and any terms or conditions contained herein, hereby
supersede any and all previous Special Orders, Enforcement Compliance Schedule Letters,
terms, conditions, and limits contained therein issued in connection with NPDES permit
number NC0024244 and Collection System Permit WQCS00016. In the event of an NPDES
permit modification or renewal, any effluent limit or monitoring requirements contained
therein shall supersede those contained in Attachment A of this Special Order by Consent,
except as modified and contained in paragraph 2(c) above.
7. This Special Order by Consent may be amended provided the City has made good faith
efforts to secure funding, complete all construction and achieve compliance within the dates
specified.
8. During the term of this Special Order by Consent, the City will not be permitted to accept
additional wastewater from any domestic, industrial, or commercial sources without prior
approval from the Mooresville Regional Supervisor and the Water Quality Permitting
Section.

* SOC Limits are effective beginning on the effective date of the SOC and lasting until the SOC
compliance date on May 31, 2026. The SOC shall expire on August 31, 2026.
Footnotes:
1. The Permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system; see Section A. (9.).
2. U = at least 100 feet above the discharge point. D1 = approximately 2620 feet below the discharge point. D2
= 3.9 miles downstream at NCSR 1967. D3 = approximately 200 yards downstream from the discharge point,
for color samples only. Stream samples shall be collected monthly from October 1 through May 30, and
weekly from June 1 through September 30.
3. The monthly average effluent BOD5 and TSS concentrations shall not exceed 15% of the respective influent
value (85% removal).
4. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the
permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina
certified laboratory (including field certified), even if these values fall below 50 µg/L.
5. Whole Effluent Toxicity shall be monitored using the Pass/Fail Chronic Toxicity test with Ceriodaphnia
dubia at 90% effluent. Samples shall be taken in March, June, September, and December; see Section A. (4.).
6. Effluent Hardness samples shall coincide with sampling of metals.
7. Total Silver shall be monitored using "clean" sampling techniques and reported to the lower reporting level of
the procedure.
8. See Section A. (6.) for Color Reopener and Monitoring Requirements.
9. The Permittee shall perform three Effluent Pollutant Scans during the term of this permit; see Section A. (5.).
10. The Permittee shall sample instream hardness, upstream of the facility's discharge. The sample shall be
representative of the hardness in the receiving stream.
b. There shall be no discharge of floating solids or visible foam in other than trace amounts.

City of Albemarle — Long Creek WWTP Improvements
Brief Project Description
The Long Creek WWTP improvements will include implementation and/or construction of the
following items:
• Perform electrical upgrades to the electrical grid at the WWTP to ensure reliability of
WWTP in accordance with 15A NCAC 2H .0124.
• Conduct engineering study of hydraulic loading to individual waste treatment trains to
operate aeration basin and secondary clarifier train independently of other treatment trains to
accommodate fluctuating flows into WWTP.
• Perform necessary construction, piping, and valving to operate each treatment train
independently of each other.
