Box 459 Magnolia, NC 28453 Subject: Permit No. WQCS00332 Town of Magnolia Magnolia Collection System Duplin County Dear Mayor Vann: ROY COOPER Uorernar MICHAEL S. REGAN Secretary LINDA CULPEPPER lnlrrim Mreelur In accordance with your application received October 17, 2017, we are forwarding herewith Permit No. WQCS00332, dated November 9, 2017, to the Town of Magnolia for the operation and maintenance of the subject wastewater collection system. This permit shall be effective from November 9, 2017 until October 31, 2025 and shall be subject to the conditions and limitations specified herein. It is your responsibility to thoroughly review this permit. Please pay particular attention to the monitoring and reporting requirements in this permit and any special conditions. Changes have been made to the boiler plate language of the permit. Most of the changes are for clarification purposes, however Condition 1(3) has been removed. The Department of Environmental Quality (DEQ) believes that condition was included erroneously in previous permits. It was included based on proposed rulemaking by EPA which was never promulgated and, in the continued absence of Federal regulations, DEQ lacks authority to include such language in a permit. DEQ will continue to exercise enforcement discretion when evaluating sanitary sewer overflows that may be considered to be beyond the reasonable control of the Permittee. A highlighted copy of the permit identifying the changes made is available at: http://ncdenr.s3.amazonaws.com/s3fs- public/Water%20Quality/Surface%20Water%20Protection %20WQCS%2OTem pdf E For purposes of permitting, the collection system is considered to be any existing or newly installed system extension up to the wastewater treatment facility property or point of connection with a separately owned sewer system. The collection system is considered all gravity lines, pump stations, force mains, low pressure sewer systems, STEP systems, vacuum systems, etc, and associated piping, valves and appurtenances that help to collect, manage and transport wastewater to a wastewater treatment plant under the Permittee's ownership or maintained and operated by the Permittee through a perpetual•legal agreement. Satellite systems are systems tributary to the Permittee's collection system but those collection systems are not owned or maintained by the Permittee. The system description provided on Page 1 of this permit is meant to provide a general idea about the size of the system and may not be all inclusive of the collection system at the time of permit issuance or afterward. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Phone: 919-807-630011nfernet: www.ncwaferquality,o,•g An Equal Opportunity %Affirmative Action Employer— Made in part by recycled paper Magnolia Collection System November 9, 2017 A discharge of wastewater to the environment from the Permittee's wastewater collection system prior to reaching the wastewater treatment facilities is referred to herein as a Sanitary Sewer Overflow (SSO). The evaluation of enforcement options after an SSO will be determined considering all relevant information available or requested of the Permittee. Compliance with all conditions of the permit as well as all statutes and regulations pertaining to the wastewater collection system must be maintained or appropriate enforcement actions may be taken as noted in Condition VI(2). A reportable SSO is an SSO greater than 1,000 gallons to the ground or an SSO of any amount that reaches surface water (including through ditches, storm drains, etc.). Reporting requirements including the required verbal report and written report to the appropriate regional office are referenced in Condition IV(2). Form CS-SSO can be downloaded from the SSO Reporting area at: http://ncdenr.s3.amazonaws.com/s3fs- public/Water%20Quality/Surface%20Water%20Protection/PERCS/WCS%20(SSO%20Documents)/CS- SSO(2015).doc A notice of deficiency (NOD), notice of violation (NOV), civil penalty, and/or a moratorium on the addition of waste to the system may be issued if adequate justification for an SSO is NOT submitted to the regional office. In order to submit a claim for justification of an SSO, you must use Part II of form CS-SSO with additional documentation as necessary. DWR staff will review the justification claim and determine if enforcement action is appropriate. Please be advised that the information needed to justify a spill is very comprehensive. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within thirty days following the receipt of this permit. 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, NC 27699-6714.
