Sullins, Director Subject: NPDES Permit Number NCS000454 Town of Stallings Dear Ms; Paxton: In accordance with the Environmental Management Commission's (EMC) Final Agency Decision of March 7, 2007, the Division is forwarding herewith your revised NPDES Phase II stormwater permit, number NCS000454. The revised permit includes new provisions for. the Goose Creek watershed, in accordance with the agency decision. Persons wishing to comment were invited to submit their comments in writing to DWQ no later than May 4, 2007. All comments received prior to that date were considered in the final determination regarding permit issuance. Our office received comments recommending more stringent stormwater controls, and other comments recommending less stringent stormwater controls. Our office also received numerous letters requesting a hearing on the permit requirements for the Goose Creek watershed. The Goose Creek watershed area has been under significant review over the last few years related to the protection of areas that support a federally listed and endangered species - the Carolina heelsplitter mussel. Further, Goose Creek is subject to an EPA approved TMDL for fecal coliform. In 2005, federally mandated stormwater discharge permits were issued for a number of local governments in the Goose Creek watershed. Environmental interest groups challenged the permits to three communities in the watershed and contended that they were not protective of the Carolina heelsplitter or its habitat. In review of this challenge an Administrative Law Judge and the EMC have set specific management strategies to be implemented in the Goose Creek watershed while a Site Specific Management Strategy is under development. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 512 N.

The revised permit includes new provisions for the Goose Creek watershed, in accordance with the agency decision. Persons wishing to comment were invited to submit their comments in writing to DWQ no later than May 4, 2007. All comments received prior to that date were considered in the final determination regarding permit issuance. Our office received comments recommending more stringent stormwater controls, and other comments recommending less stringent stormwater controls. Our office also received numerous letters requesting a hearing on the permit requirements for the Goose Creek watershed. The Goose Creek watershed area has been under significant review over the last few years related to the protection of areas that support a federally listed and endangered species -- the Carolina heelsplitter mussel. Further, Goose Creek is subject to an EPA approved TMDL for fecal coliform. In 2005, federally mandated stormwater discharge permits were issued for a number of local governments in the Goose Creek watershed. Environmental interest groups challenged the permits to three communities in the watershed and contended that they were not protective of the Carolina heelsplitter or its habitat. In review of this challenge an Administrative Law Judge and the EMC have set specific management strategies to be implemented in the Goose Creek watershed while a Site Specific Management Strategy is under development. 1617 Mail Service Center, Raleigh, North Carolina 27699.1617 512 N.

Proposed permit modifications must be submitted to the Director for approval. i 1. If the permitted MS4 becomes subject to an approved TMDL, and following notice of such by the Division, the permittee shall implement a TMDL Water Quality Recovery Program. The following additional requirements apply. (a) Within two years after receiving the Division's notice that the permittee is subject to a TMDL, the permittee shall establish a TMDL Water Quality Recovery Program and shall identify the locations of all currently known MS4 outfalls within its jurisdictional area with the potential of discharging the pollutant(s) of concern: to the impaired segments, to their tributaries, and to segments and tributaries within the watershed contributing to the impaired segments. The permittee shall also develop a schedule to discover and locate all other MS4 outfalls within its jurisdictional area that may be discharging the pollutant(s) of concern: to the impaired stream segments, to their tributaries, and to segments and tributaries within the watershed contributing to the impaired segments. (b) Within two years after receiving the Division's notice that the permittee is subject to a TMDL, the permittee shall develop a monitoring plan for each pollutant of concern. The monitoring plan shall include the sample location by verbal description and latitude and longitude coordinates, sample type, frequency, any seasonal considerations, and a monitoring implementation schedule for each pollutant of concern. Where appropriate, the permittee may reduce the monitoring burden by proposing to monitor outfalls that the Division would consider substantially similar to other outfalls. The permittee may also propose in -stream monitoring where it would complement the overall monitoring plan. The monitoring plan shall be adjusted as additional outfalls are identified in accordance with the schedule required in (a) above and as accumulating data may suggest. (c) The permittee shall include the'location of all currently known MS4 outfalls with the potential of discharging the pollutant(s) of concern, the schedule for discovering and locating currently unknown MS4 outfalls with the potential of discharging the pollutant(s) of concern, and the monitoring plan, (all as required in (a) and (b) above, and all part of the TMDL Water Quality Recovery Program) in the first Stormwater Plan annual report due no earlier than two years after the Division's initial notification of the applicability of a TMDL. (d) The next and each subsequent Stormwater Plan annual report shall include an assessment of the available data for each pollutant of concern, and an assessment of the effectiveness of the BMPs employed, to determine what, if any, additional BMP measures may be necessary to return the impaired segments to compliance Part H Page 2 of 12 Permit No. NCS000454 with state water quality standards. The permittee shalt implement appropriate BMPs to control the pollutant(s) of concern to the maximum extent practicable. Implementation of the appropriate best management practices constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. (e) Following any review and comment by the Division on the TMDL Water Quality Recovery Program, the permittee shall incorporate any necessary changes into the program. The permittee shall incorporate the revised TMDL Water Quality Recovery Program into the Stormwater Plan. The permittee can identify the impaired stream segments in the MS4 jurisdictional area by referencing the 2004 Integrated 305(b) and 303(d) Report (or current version), available on the website of the Division of Water Quality Modeling and TMDL Unit. 12. Municipalities shall incorporate in their Stormwater Plan site -specific stormwater management requirements for streams supporting federally -listed threatened and endangered aquatic animal species required by site -specific management plans and .schedules developed under provisions of 15A NCAC 2B .0110.

The NCDENR Division of Land Resources Erosion and Sediment Control Program meets the requirements of the Construction Site Runoff Controls by permitting and controlling development activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development. This program includes procedures for public input, sanctions to ensure compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices, review of site plans which incorporates consideration of potential water quality impacts, and procedures for site inspection and enforcement of control measures. NCDENR Division of Water Quality NPDES general permit for construction activities (NCG1.0000), specifically Part I, Section A, Paragraphs 3, 4, 5, and 6, establishes requirements for construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality. The permittee must provide and promote a means for the public to notify the appropriate authorities of observed erosion and sedimentation problems. The permittee may implement a plan promoting the NCDENR, Division of Land Resources "Stop Mud" hotline to meet the requirements of this paragraph. The permittee may pursue local government implementation of the Erosion and Sediment Control Program by requesting a "minor modification" to the permit.

Total Maximum Daily Load (TMDL) A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed water quality assessment that provides the scientific foundation for an implementation plan. The implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to restore and maintain water quality standards in all seasons. The Clean Water Act, Section 303, establishes the water quality standards and TMDL programs. 23. Toxic Pollutant Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
