IN THE MATTER OF )
NORTH CAROLINA ) SPECIAL ORDER BY CONSENT
NPDES PERMIT NCO020737 ) EMC SOC WQ S16-001 Ad I
HELD BY THE CITY OF KINGS MOUNTAIN)
Pursuant to provisions of North Carolina General Statute (G.S.) 143-215.2 and G.S. 143-215.67, this
Special Order by Consent is entered into by the City of Kings Mountain, 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. 14313-282, and hereinafter referred to as the Commission:
The City and the Commission hereby stipulate the following.
(a) The City holds North Carolina NPDES Permit NCO020737 for operation of an existing
wastewater treatment works and for making an outlet therefrom for treated wastewater to
Buffalo Creek, Class C waters of this State in the Broad River Basin, but is unable to
consistently comply with effluent thallium limitations as set forth in NPDES Permit
NCO020737 due to the indirect discharge of thallium by a permitted significant industrial
user. Compliance will require the City to provide appropriate oversight of its permitted
industrial pretreatment program to ensure the significant industrial user implements the
necessary corrective actions to comply with the industrial user's permitted thallium limits.
(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) Implementation of the City's industrial pretreatment program is authorized under the
NPDES Permit NC0020737, including the authority to approve construction/repairs and/or
improvements to the industrial user's wastewater treatment system, which, once
implemented, will be sufficient to adequately treat wastewater presently being discharged to
the City's collection system to the extent the City will be able to comply with final effluent
permit limitations in NPDES Permit NC0020737.
(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 Permit identified in paragraph 1(a) above, hereby agrees
to do the following:
(a) Provide the Mooresville Regional Office of the North Carolina Division of Water
Resources (DWR), located at 610 East Center Ave, Suite 301, Mooresville, NC 28115,
with a list of all additions of flow (see paragraph 5) under the City's Special Order by
Consent, and update this list each time flow is added to the collection system.

4. The City and the Commission agree stipulated penalties are not due if the City satisfies to the
Division of Water Resources 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. 15013-23, 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.
In accordance with the provisions of G.S. 143-215.67(b) the Commission allows the City to
accept 2.0 MGD of additional wastewater to its waste treatment system during the term of the
SOC.
The nature of the additional flows is such 'Chat the waste characteristics do not exceed those
generally associated with domestic waste or are pretreated to domestic strengths. Waste of
greater than normal domestic strength may be accepted if the parameter(s) that exceed normal
domestic strength wastewater are not those for which interim limitations have been developed
and it can be demonstrated to the satisfaction of the Director the additional waste will not
adversely affect the treatment efficiency of the treatment system for any modified parameter or
result in the violation of any other permit limitation. All new and proposed industrial waste
tributary to the system must be controlled using all needed mechanisms including but not
limited to adoption and implementation of industrial waste control and pretreatment
ordinances. No wastewater can be accepted which will add toxic pollutants in quantities not
generally associated with domestic wastewater characteristics, unless the acceptance of the
additional wastewater can be supported through appropriate analyses acceptable to the Director.
6. This Special Order by Consent and any terms, conditions, and interim effluent limitations
contained herein, hereby supersede any and all previous Special Orders, Enforcement
Compliance Schedule Letters, terms, conditions, and limitations contained therein issued in
connection with NPDES Permit NC0020737. In the event of an NPDES Permit modification or
renewal, any effluent limitations 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(d) above.
7. Any violation of the terms of this Special Order by Consent, including paragraphs 2(b), 2(c) and
2(d) above and Attachment A may, upon the discretion of the Director, terminate paragraph
five (5) of this Order.
8. 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).
9. The Permittee, upon signature of this Special Order by Consent, will be expected to comply
with all schedule dates, terms, and conditions of this document.
