If subject to an approved TMDL with a NPDES MS4 regulated WLA assigned to the permittee, the permittee will be considered in compliance with the TMDL if the permittee complies with the conditions of this permit, including developing and implementing appropriate BMPs within the six minimum measures to address the permittec's MS4s NPDES regulated WLA to the maximum extent practicable (MEP). While improved water quality is the expected outcome, the permittee's obligation is to implement BMP's designed to address the NPDES regulated waste load allocation assigned to the permittee to the maximum extent practicable (MEP). The permittee is not responsible for attaining water quality standards (WQS). The Division expects attaining WQS will only be achieved through reduction from all point and nonpoint source contributors identified in the approved TMDL. 2. TMDL Plans a. If the permittee has an existing TMDL Plan designed to address the NPDES MS4 regulated WLA assigned to the permittee, that includes monitoring to evaluate progress, and which addresses the POC through the six minimum control measures; it satisfies the objectives of this Section H. b. The permittee may comply with a Department approved management strategy to address an impairment or TMDL, such as a Nutrient Management Strategy, to satisfy the objectives of this Section H. c. The permittee may develop and submit, within 24 months, to the Department for approval of an alternative approach, such as an Integrated Report - Category 4(b) watershed plan, to satisfy the objectives of this Section H. d. For new TMDLs that are not addressed by H.2. a, b, or c above, a TMDL Plan shall be developed according to H.3 below, and submitted to the Division. Time periods shown are from the later of the effective date of this permit or the TMDL as approved by EPA. Part II Page 14 of 18 PERMITNO. NCS000406 3.

NCS000406 PART I PERMIT COVERAGE 1. During the period beginning on the effective date of the permit and lasting until expiration, the City of Wilmington is authorized to discharge stormwater from the municipal separate storm sewer system (MS4) to receiving waters of the State within the Cape Pear River Basin. Such discharge will be controlled, limited and monitored in accordance with the permittee's Comprehensive Stormwater Management Program, herein referred to as the Stormwater Plan. The Stormwater Plan must detail the permittee's stormwater management program for the five- year term of the stormwater permit including, for each of the measure identified in the permit, a narrative description of the program, a table that identifies each best management practice (BMP) used, the frequency of the 13MP, the measurable goals for each BMP, the implementation schedule, funding and the responsible person or position for implementation.. 2. All discharges authorized herein shall be adequately managed in accordance with the terms and conditions of this permit. Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non-stormwater discharge or is covered by another pennit, authorization, or approval. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree. This pen -nit covers activities associated with the discharge of stormwater from the MS4 within the jurisdictional area of the pennittee as described in the approved local Stormwater Plan to control potential pollution from the MS4. The pen -nit applies to current and future jurisdictional areas of the permittee, as well as areas that seek coverage under this pen -nit through inter -local or other similar agreements with pennittee. Agreements for coverage under this permit must be approved by the Division of Water Quality; herein referred to as the Division. The Division may deny or revoke coverage under this permit for separate entities and require independent permit coverage as deemed necessary. In addition, the pernittee.may petition the Division to revoke or deny coverage under this permit for specific entities. Under the authority of Section 402(p) of the Clean Water Act and implementing regulations 40 CI+R Part 122, 123 and 124, North Carolina General Statutes 143-215.1 and Session Law 2004- 163 and in accordance with the approved Stonnwater Plan, all provisions contained and referenced in the Stormwater Plan are enforceable parts of this permit. The pennittee will develop and implement its approved Stonnwater Plan in accordance with Section 402(p)(3)(B) of the Clean Water Act, provisions outlined by the Director, and the provisions of this pennit. 7. The permit requires the development and proper implementation of the Stormwater Management Plan. The purpose of the Stonnwater Management Plan is to reduce the discharge of pollutants from the MS4 to the maximum extent practicable, to protect water quality, and to satisfy the applicable water quality requirements of the Clean Water Act. Implementation of best management practices consistent with the provisions of the Stonnwater Management Plan constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. Successive iterations of the Stormwater Management Plan and other components of this permit will be driven by the objective of assuring that discharges do not cause or contribute to the violation of water quality standards, through the expansion and tailoring of management measures within the scope of the Stormwater Management Plan. Part I Page 1 of 2 PERMIT NO. NCS000406 8. The permit authorizes the point source discharge of stormwater runoff from the MS4. In addition, discharges of non-stormwater are also authorized through the MS4 of the permittee if such discharges are: (a) Permitted by, and in compliance with, another NPDES discharge permit including discharges of process and non -process wastewater, and stormwater associated with industrial activity; or (b) Determined to be incidental non-stormwater flows that do not significantly impact water quality and may include: • water line flushing; • landscape irrigation; • diverted stream flows; • rising groundwaters; • uncontaminated groundwater infiltration; • uncontaminated pumped groundwater; • discharges from potable water sources; • foundation drains; • air conditioning condensate (connrterciai/residential); • irrigation waters (does not include reclaimed water as described in 15A NCAC 214 .0200); • springs; • water from crawl space pumps; • footing drains; • lawn watering; • residential and charity car washing; • flows from riparian habitats and wetlands; • dechlorinated swimming pool discharges,' • street wash water; • Mows from emergency fire fighting. The Division may require that non-stormwater flows of this type be controlled by the permittee's Stonnwater Plan. Part I Page 2 of 2 PERMIT NO. NCS000406 PART 11 FINAL LIMITATIONS AND CONTROLS FOR PERMITTED DISCIIARGES SECTION A: PROGRAM IMPLEMENTATION The pennittee will implement, manage and oversee all provisions of its Stormwater Plan to reduce pollutants discharged from the MS4. This includes, but is not limited to, the following areas: The pennittee will develop and maintain adequate legal mechanism, such as regulations, ordinances, policies and procedures to implement all provisions of the Stormwater Plan. The permittee will keep the Division advised of the status of development of appropriate ordinances and legal authorities and will pursue these authorities in accordance with the schedule outlined in the Stonnwater Plan. The permittee's Stonnwater Plan will be implemented and managed such that the discharge of pollutants from the MS4 is reduced to the maximum extent practicable. It is anticipated that in order to meet this provision, implementation of the Stormwater Plan will occur with emphasis given to priority areas and to management measures and programs that are most effective and efficient at varying stages of the plan's implementation. The pennittee will implement the components of the Stormwater Plan to prohibit, to the maximum extent practicable, illicit connection§, spills and illegal dumping into the MS4, 4. The permittee will implement provisions of the Stonnwater Plan as appropriate to monitor and assess the performance of the various management measures that are a part of the Stormwater Plan. This will include the provisions of this permit. The permittee will implement appropriate education, training, outreach, and public involvement programs to support the objectives of this stormwater discharge permit and the Stormwater Plan. 6. The permittee will implement a program to reduce pollution from construction site runoff as described in the Stormwater Plan and in accordance with this permit. 7. The pennittee will implement a post -construction site runoff control program to regulate new development and redevelopment by requiring structural and non-structural best management practices to protect water quality, to reduce pollutant loading, and to minimize post -development impacts. This program will include provisions for long-term operation and maintenance of 13MPs. The permittee will evaluate municipal operations and develop and implement an appropriate program for municipal activities and ongoing operation and maintenance of municipal facilities to reduce the potential for stonnwater pollution. 9. Proposed permit modifications must be submitted to the Director for approval. 10. ' 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 pennittee is subject to a 'TMDL, the permittee shall establish a TMDL Water Quality Recovery Program and shall Page I of 15 PERMIT NO. NCS000406 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 schcdulc 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 pernttee 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 pemiittee 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 Management 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 Management 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 with state water quality standards. The permittee shall implement appropriate BMPs to control the pollutant(s) of concern to the maximum extent practicable. I nplementation 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 permittce shall incorporate the revised 'TMDL Water Quality Recovery Program into the Stormwater Management Plan.

(9) The Randleman Lake Water Supply Watershed Nutrient Management Strategy — 15A NCAC 2B.0251. (b) In order to fulfill the post -construction minimum measure program requirement, a permittee, delegated program, or regulated entity may use the Department's model ordinance, design its own post -construction practices based on the Department's guidance on scientific and engineering standards for best management practices (BMPs), incorporate the post -construction model practices described herein, or develop its own comprehensive watershed plan that is determined by the Department to meet the post -construction stormwater management measure: (c) Permittees must require stormwater controls for a project that disturbs one acre or more of land, including a project that disturbs less than one acre of land that is part of a larger common plan of development or sale. The stonnwater controls shall be appropriate to the project's level of density as follows: (1) Post -construction model practices for low -density projects. —A project that is located within one-half mile of and draining to Shellfish Resource Waters is a law -density project if it contains no more than twelve percent (12%) built -upon area. A project that is not located within one-half mile of Shellfish Resource Waters is a low -density project if it contains no more than twenty-four percent (24%) built -upon area or no more than two dwelling units per acre. Low -density projects must use vegetated conveyances to the maximum extent practicable to transport stormwater runoff from the project. On -site stonnwater treatment devices such as infiltration areas, bioretention areas, and level spreaders may also be used as added controls for stormwater runoff. A project with an overall density at or below the low -density thresholds, but containing areas with a density greater than the overall project density, may be considered low density as long as the project meets or exceeds the post -construction model practices for low -density projects and locates the higher density in upland areas and away from surface waters and drainageways to the maximum extent practicable. (2) Post -construction model practices for high -density projects. — A project that is located within one-half mile of and draining to Shellfish Resource Waters is a high -density project if it contains more than twelve percent (12%) built -upon area. A project that is not located within one-half mile of Shellfish Resource Waters is a high -density project if it contains more than twenty-four percent Page 11 of 15 PERMIT NO. NCS000406 (24%) built -upon area or more than two dwelling units per acre. High -density projects must use structural stormwater management systems that will control and treat control and treat runoff from the first one and one-half inches of rain. In addition, projects that are located within one-half nine and draining to Shellfish Resource Waters must control and treat the difference in the stormwater runoff from the predevelopment and post -development conditions for the one-year, 24- hour storm. The structural stormwater management system must also meet the following design standards: A. Draw down the treatment volume no faster than 48 hours, but no slower than 120 hours. B. Discharge the storage volume at a rate equal to or less than the predevelopment discharge rate for the one-year, 24-hour storm. C. Remove an eighty-five percent (85%) average annual amount of Total Suspended Solids. D. Meet the General Engineering Design Criteria set out in 15A NCAC 02H .1008(c) or a locally approved stormwater management manual. E. Wet detention ponds designed in accordance with the requirements of Paragraph (3)(d) may be used for projects draining to Class SA waters. (d) For areas draining to Class SA waters, permittees, delegated programs, and regulated entities must: (1) Use BMPs that result in the highest degree of fecal coliform die -off and control to the maximum extent practicable sources of fecal coliform while still incorporating the stormwater controls required by the project's density level. (2) Implement a program to control the sources of fecal colifonn to the maximum extent practicable, including a pet waste management component, which may be achieved by revising an existing litter ordinance, and an on -site domestic wastewater treatment systems component to ensure proper operation and maintenance of such systems, which may be coordinated with local county health departments. (3) Prohibit new points of stormwater discharge to Class SA waters and prohibit both increases in the volume of stormwater flow through conveyances and increases in capacity of conveyances in existing stormwater conveyance systems that drain to Class SA waters. Any modification or redesign of a stomwater conveyance system within the contributing drainage basin must not increase the net amount or rate of stormwater discharge through existing outfalls to Class SA waters. Diffuse flow of stormwater at a nonerosive velocity to a vegetated buffer or other natural area capable of providing effective infiltration of the runoff from the one-year, 24-hour storm shall not be considered a direct point of stormwater discharge. Consideration shall be given to soil type, slope, vegetation, and existing hydrology when evaluating infiltration effectiveness. (e) For BMPs that require a separation from the seasonal high-water table, the separation shall be provided by at least 12 inches of naturally occurring soil above the seasonal high-water table.

Certain waters provide habitat for federally -listed aquatic animal species that are listed as threatened or endangered by the U.S. Fish and Wildlife Service or National Marine Fisheries Service under the provisions of the Endangered Species Act, 16 U.S.C. 1531-1544 and subsequent modifications. 2. The shortnose sturgeon (Rcipenser brevirostrum) was listed as endangered on March 11, 1967 (32 FR 4001) and remained on the endangered species list with enactment of the ESA in 1973. Shortnose sturgeon occur in most major river systems along the eastern seaboard of the United States. Shortnose sturgeon inhabit the main stems of their natal rivers, migrating between freshwater and mesohaline river reaches. Spawning occurs in upper, freshwater areas, while feeding and overwintering activities may occur in both fresh and saline habitats. Under the provisions of the Final Recovery Plan published by the National Marine Fisheries Service (NMFS) in December 1998, the permittee shall implement measures to increase awareness of shortnose sturgeon and their status by formulating a public education program that generates public interest in sturgeon and sturgeon recovery by contacting media outlets, suggesting feature stories, and using existing forums for educating the public (e.g., public aquaria, FWS Partners for Wildlife Program, private foundations). Articles, posters, and pamphlets should be published to increase public knowledge of shortnose sturgeon and their unique and complex life history. This information may include identifiable features of the species, listing status, range, susceptibility to incidental captures, and a number or address to report sightings or captures. The permittee shall offer to work with schools to develop and evaluate educational materials and curricula that introduce students to sturgeons, the river/estuarine environment, and the ESA.

Grab Sample An individual sample collected instantaneously. Grab samples that will be directly analyzed or qualitatively monitored must be taken within the first 30 minutes of discharge. 11. Hazardous Substance Any substance designated in 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. 12. Illicit Discharge Any discharge to a MS4 that is not composed entirely of stormwater except discharges pursuant to an NPDES permit (other than the NPDES MS4 permit), allowable non-stormwater discharges, and discharges resulting from fire -fighting activities. 13. Industrial Activity For the purposes of this permit, industrial activities shall mean all industrial activities as defined in 40 CFR 122,26. 14. Major municipal separate storm sewer outfall (or "major outfall") Major municipal separate storm sewer outfall (or "major outfall") means a municipal separate storm sewer outfall that discharges from a single pipe with an inside diameter of 36 inches or more or its equivalent (discharge from a single conveyance other than circular pipe which is associated with a drainage area of more than 50 acres); or for municipal separate storm sewers that receive storm water from lands zoned for industrial activity (based on comprehensive zoning plans or the equivalent), an outfall that discharges from a single pipe with an inside diameter of 12 inches or more or from its equivalent (discharge from other than a circular pipe associated with a drainage area of 2 acres or more). 15. Municipal Separate Storm Sewer System (MS4) Pursuant to 40 CFR 122.26(b)(8) means a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains): (a) Owned or operated by the United States, a State, city, town, county, district, association, or other public body (created by or pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under State law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or Part VIII Page 2 of 4 • PERMIT NO.

Non-stormwater Discharge Categories The following are categories of non-stonnwater discharges that the permittee must address if it identifies them -as significant contributors of pollutants to the storm sewer systern: water line flushing, landscape irrigation, diverted stream flows, rising groundwater, uncontaminated groundwater infiltration, [as defined in 40 CFR 35.2005(20)], uncontaminated pumped groundwater, discharges from potable water sources, foundation drains, air conditioning condensation, irrigation water, springs, water from crawl space pumps, footing drains, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, dechlorinated swimming pool discharges, and street wash water (discharges or flows from fire fighting activities are excluded from the definition of illicit discharge and only need to be addressed where they are identified as significant sources of pollutants to waters of the United States). 17. Non-structural BMP Non-structural BMPs are preventive actions that involve management and source controls such as: (1) Policies and ordinances that provide requirements and standards to direct growth to identified areas, protect sensitive areas such as wetlands and riparian areas, maintain and/or increase open space, provide buffers along sensitive water bodies, minimize impervious surfaces, and/or minimize disturbance of soils and vegetation; (2) policies or ordinances that encourage infill development in higher density urban areas, and areas with existing storm sewer infrastructure; (3) education programs for developers and the public about minimizing water quality impacts; (4) other measures such as minimizing the percentage of impervious area after development, use of measures to minimize directly connected impervious areas, and source control measures often thought of as good housekeeping, preventive maintenance and spill prevention. 18. Outfall Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate storm sewer discharges to waters of the United States and does not include open conveyances connecting two municipal separate storm sewers, or pipes, tunnels or other conveyances which connect segments of the same stream or other waters of the United States and are used to convey waters of the United States. 19.

Point Source Discharize of Stormwater Any discernible, confined and discrete conveyance including, but not specifically limited to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater is or may be discharged to waters of the state. 21. Redevelopment Means any rebuilding activity unless that rebuilding activity; (a) Results in no net increase in built -upon area, and (b) Provides equal or greater storrmwater control than the previous development. 22. Stonnwater Runoff The flow of water which results from precipitation and which occurs immediately following rainfall or as a result of snowmelt. 23. 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. 24. Toxic Pollutant Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
