The permittee shall amend the SPPP whenever there is a change in design, construction, operation, site drainage, maintenance, or configuration of the physical features which may have a significant effect on the potential for the discharge of pollutantsto surface waters. Date Description of Amendment/Update Authorized Signature • 1. GENERAL INFORMATION 1.1 STORMWATER DISCHARGE PERMIT In North Carolina (NC), coverage must be obtained under General Permit No. NCG190000 (NCG 190) to discharge stormwater associated with operating Marinas, standard industrial classification (SIC) 4493, and/or Ship and Boat Building and Repair, SIC 373, to surface waters under the National Pollutant Discharge Elimination System's (NPDES) program established under the Clean Water Act (CWA). Part II, Section A of the NCG190 requires the development, maintenance and implementation of a Stormwater Pollution Prevention Plan (SPPP). This document shall serve as the SPPP for Dudley's Marina, Inc. A copy of this general permit has been included as Appendix A and should be replaced once coverage has been obtained by the State to ensure any specific requirements have been captured. 1.2 STORMWATER POLLUTION PREVENTION PLAN A SPPP defines a program to control stormwater discharges from potential pollutant sources identified at a specific facility. Additionally, a SPPP maps these potential pollutant sources that are exposed to and may reasonably be expected to contribute to the contamination of stormwater discharges. Potential pollutant sources usually generate from facility practices classified as • industrial activities. Such sources can include outdoor hazardous material storage areas, fueling and maintenance areas and waste disposal practices exposed to stormwater. • Based on pollutant sources and exposures, best management practices (BMPs) are implemented to either eliminate materials from stormwater exposure or provide adequate control to reduce pollutant discharges. BMPs may be either structural, such as secondary containment structures for aboveground storage tanks (ASTs), or non-structural, such as standard operating procedures (SOPs) for maintenance and repair. This plan shall be considered as the SPPP for Dudley's Marina, Inc. and must be reviewed in its entirety and updated on an annual basis. At a minimum, updates shall include the following: ■ a list of significant spills and/or leaks of pollutants for the previous three (3) years, or notation that no spills and/or leaks have occurred; ■ re -certification that stormwater outfalls have been evaluated for the presence of non- stormwater discharges; ■ documentation of re-evaluation of on-site stormwater BMP effectiveness; ■ review and comparison of past year's monitoring data to benchmark values. 1 of 14 • 1.3 PROCEDURAL REQUIREMENTS All requirements of the NCG190 must be met in order to maintain a compliant facility. The site specific issued permit should be referenced for more detailed information. Requirements of the general permit include the following: ■ Develop and implement a SPPP; ■ Conduct facility inspections; ■ Provide training to personnel; ■ Identify facility personnel responsible for implementation of the SPPP ■ Implement a monitoring program ■ Update the SPPP annually; ■ Maintain the SPPP and reports included herein for a minimum period of 5 -years. 1.4 FACILITY INFORMATION Dudley's Marina, established in 1938, is a full service marina located in Carteret County, North Carolina (NC), and is bordered to the north by State Route 24 (Cedar Point Boulevard) and the White Oak River, and to the south and west by the Intracoastal Waterway (Figure 1). Dudley's Marina offers both floating and stationary docks that can accommodate vessels up to 125 feet in • length as well as inside and outside dry storage. In addition to docking accommodations, other services are offered including refueling areas, maintenance and repair services and a complete ship's store. Dudley's Marina is owned and operated by John W. Dudley. • 2of14 • • Fiume 1. Dudley's Marcia Location Map • • 2. STORMWATER POLLUTION PREVENTION TEAM The Stormwater Pollution Prevention Team (SPPT) at Dudley's Marina is tasked with the responsibility of overseeing implementation of the SPPP and associated BMPs at the facility. The predominant functions of the SPPT include, but are not limited to, the following: ■ Ensure compliance with NCG190 permit requirements ■ Determine and procure appropriate pollution control equipment and materials. ■ Review and prioritize the implementation of structural and non-structural BMPs. ■ Supervise the implementation of appropriate BMPs. ■ Inspect and oversee the maintenance of structural BMPs. ■ Conduct facility inspections. SPPT members have been identified in Table 1. This table should be updated whenever there is a change in SPPT personnel. The following sections discuss individual SPPT roles and associated responsibilities. 2.1 STORMWATER POLLUTION PREVENTION MANAGER (SPPM) The SPPM is responsible for overall implementation of pollution prevention initiatives, including • SPPP provisions at Dudley's Marina. The SPPM will perform the following: ■ Supervise and direct staff and contractors' work to support pollution prevention initiatives. ■ Provide pollution prevention awareness guidance and education to facility patrons ■ Track the progress of SPPP implementation ■ Update the SPPP on an annual basis ■ Provide SPPP training to all staff members and outside contractors ■ Oversee spill prevention and response operations ■ Have oversight of facility inspection and monitoring programs 2.2 STORMWATER COMPLIANCE ASSESSORS The SPPP Compliance Assessors are responsible for ensuring compliance with SPPP provisions by conducting inspections and providing training to facility personnel and patrons. SPPP Compliance Assessors report to the SPPM and will carry out the following: ■ Assist the SPPM in implementing and ensuring compliance with SPPP and NCG190 permit provisions. ■ Maintain proper records as required by the SPPP and NCG190 permit. ■ Conduct and document facility inspections. ■ Monitor stormwater discharges in accordance with permit specifications. 4 of 14 �J • Table is Sttiriat+et P1lufio Prevnft:.,�".

POTENTIAL POLLUTANT SOURCES AND BMPS Due to a marina's close proximity to waterways, there is a higher potential for marina waters to become contaminated from polluted stormwater runoff generated during various facility specific activities such as boat cleaning, fueling operations, and boat maintenance. Runoff can be in the form of sheet flow across generally flat areas or can be channeled into discernable conveyances, ultimately discharging through outfalls into surface water. Dudley's property can be divided into seven (7) separate drainage areas; each with its own individual stormwater discharge outfall (SDO) point. Of these, three (3) contain practices that can be considered as industrial activities and should therefore be included in the monitoring program discussed in Section 5. Table 2 provides a list of facility specific practices, associated potential pollutants as well as implemented good housekeeping practices and BMPs currently in place. Additionally, drainage areas and facility practices have been identified on Figure 2. 3.1 SURFACE PREPARATION AND PAINTING ACTIVITIES Hull maintenance, to include sanding, pressure washing and scraping, is a common practice at marinas and aims to control fouling and corrosion. Wastes generated from these practices can contain metals, solvents and hydrocarbons. Boats are routinely removed from the water for hull maintenance by the boat owner or their hired contractor or by marina staff. Dudley's Marina prohibits the use of any detergents or additives in pressure wash water as well as any surface preparation activities during windy conditions. Plastic sheeting and/or tarps are used where possible to collect waste generated during these activities and the area is visually inspected and cleaned at the end of surface preparation and painting activities. When possible, wash water from pressure washing activities is collected and allowed to settle prior to discharging to grassy areas. All paints and solvents used are mixed indoors to reduce the chance of spillage into the environment. Materials are readily available for the immediate cleanup of drips and spills. 5of14 • Table 2.

Dudley's Marina conducts engine maintenance at designated facility locations. Materials used in these day-to-day operations such as solvents, antifreeze, acids, fuels and lubricants, and batteries are stored indoors. These materials are only brought out during use and returned to their inside storage locations following use. Rags used during maintenance, which contain oils and solvents, are collected in on-site containers and picked up by an outside contractor for cleaning and/or disposal. In the event of rain, engine maintenance operations either cease or are moved to an indoor location if possible. Limiting engine maintenance to dry weather conditions and maintaining materials indoors prevents exposure to stormwater and therefore greatly reduced the likelihood of these materials reaching surface waters. 3.3 MATERIAL HANDLING, TRANSFER, STORAGE AND DISPOSAL Used Oil Tank All hazardous material storage areas are located indoors to eliminate exposure to the elements with the exception of the used oil, above ground storage tank (AST). Used oil from facility maintenance activities is collected in a container located adjacent to the large bay doors of the • maintenance shop. The container is marked "Used Oil" and has a lid that remains closed when not in use. To ensure that the container is used for its intended purpose, only marina personnel are authorized to dispose of used only in the container. The AST sits in a diked concrete secondary containment structure that has more than sufficient space to contain 110% of the container's contents in the event of total tank failure. Personnel will move the container into the maintenance shop in the event of potential flooding due to heavy rains, tropical storms and/or hurricanes. Rainwater accumulated in the secondary containment can be released to adjacent grassy areas if found to be uncontaminated following a visual inspection. The secondary containment shall be visually inspected for the presence of a sheen or other POL indicator. All inspections shall be documented prior to releasing any accumulated rainwater from the secondary containment. Under no circumstances should rainwater with a visible oily sheen be released from the containment area. Records documenting accumulated rainwater release shall be maintained in Appendix B for a period of five (5) years. Fueling Dudley's Marina has four (4) dockside fueling areas and one (1) vehicle fueling area. All fueling areas are fed from centrally located underground storage tanks (USTs). The USTs are connected to a Veeder-Root tank gauging system with a visual and audible alarm. Ullage reports are pulled from the system and discussed with the fuel delivery contractor before any fuel deliveries are 8of14 • received. All fuel pumps are connected to an audible notification system inside the ship's store. Before a patron can use a fuel pump, it must be turned on by a marina staff member. This allows the marina to control use of the fueling stations and limits any misuse outside of normal operating hours. The vehicle fueling area is under a canopy and is protected from direct rainfall. Incidental spills and drips are cleaned up with absorbent material as soon as they are observed. All stormwater runoff from this area is collected in a bioretention basin which was voluntarily installed by the facility owner. Dockside fueling areas are continuously monitored by personnel. A spill kit is centrally located which allows for quick response in the event of an accidental release. Marina patrons are discouraged to "top off' fuel tanks as this usually results in minor overflows and spillage. Solid Waste Individual solid waste containers are located throughout the property and are enclosed within wooden frame structures which keep the containers secure and eliminates the risk of them being turned over. Solid waste from individual trash cans are transferred to a large, onsite dumpster. Cans are emptied into the facility dumpster as needed, but no less than once each day. Dumpster lids and doors remain closed whenever dumpsters are not in use. Marina personnel periodically conduct visual inspections of solid waste containers to ensure hazardous materials are not being • improperly disposed of in the trash. 4. SPILL PREVENTION AND RESPONSE PROCEDURES Everyday materials have the potential to contaminate stormwater runoff through spills and/or exposure of materials. In order to reduce the potential for pollution, all staff members must ensure that materials are properly maintained and disposed of. Additionally, any accidental spills or releases of hazardous materials shall be contained and cleaned up in accordance with this section. A list of all significant spills and/or leaks occurring during the previous three (3) years shall be maintained. Document information related to the spill on the Spill or Incident Reporting Form and maintain a copy with the listing of significant spills. Additionally, it is recommended to take inventory of and document the condition of spill response equipment on hand to ensure that the facility is as prepared as possible in the event of an accidental release. Documentation of significant spills and leaks and spill response equipment inventory shall be maintained in Appendix C. Dudley's Marina maintains and utilizes hazardous materials in very small, individual sized quantities with the exception of gasoline, diesel fuel, and used oil. These three petroleum products are the largest potential pollutant sources, with regard to stormwater contamination and • entering waterways. 9of14 The SPPT identified in Table 1 is responsible for implementing these spill prevention and response procedures. In addition to the implementation of response procedures, SPPT members are responsible for conducting monthly inspections and maintaining inventory of spill response equipment and educating fellow employees on these procedures. Spill response priorities are as follows: 1. Stop the source of the release if it is safe to do so. 2. If spill is on land, prevent material from reaching surface waters. 3. If spill is in water, contain the spill so it doesn't spread. 4. Conduct clean-up operations. Upon discovery of a petroleum spill on land or in the water immediately stop the source of the release if safe to do so. If the spill is on land, prevent the product from entering waterways by blocking waterway entry points. Use adsorbent pads, matting, booms and earthen dikes and diversionary measures to contain spilled product. If the spill occurs in the water use best judgement as to what measures shall be deployed (i.e. absorbent pads, matting and/or boom). If spill is large, the boom shall be deployed to contain product or deflect product to an isolated area where it can be collected. If any danger to the health and/or safety of employees exists from the spill, only those methods • which would allow for minimum contact with the spill area will be undertaken. Note: Fuel/Oil spills that reach surface waters must be immediately reported to both the NCDEQ and the National Response Center (NRC). A discharge of fuel/oil on land must be reported to the NCDEQ within 24 hours of the discharge if any of the following apply: • Volume discharged to land is 25 gallons or more • Any amount discharged to land that is 100 feet or less from any surface water Volume discharged to land is less than 25 gallons and is not able to be cleaned up within 24 -hours Contact the identified contractor to perform clean-up procedures. Document information on spill response and maintain a copy of all spill records in this SPPP.

GOOD HOUSEKEEPING PRACTICES Implementing good housekeeping practices is a cost-effective way to maintain a clean and orderly facility. Good housekeeping practices include establishing procedures to reduce the likelihood of material and/or equipment mishandling, operation and maintenance schedules, routine inspections, and a training program to ensure all staff members understand proper procedures and to ensure continued implementation of these measures. • Facility inspections are a requirement of the NCG190 and are to be completed by a SPPT member semi-annually, at a minimum. One inspection must be conducted during the first half of the year (January -June) and one during the second half (July -December), with at least 60 days in between. Facility inspections must be documented, including any planned or taken corrective actions. Any deficiencies identified during each inspection shall be elevated to the SPPM with proposed corrective actions. Maintain a copy of these reports in Appendix D. Providing proper initial training as well as refresher training to all personnel is key for complete implementation of stormwater management and pollution prevention practices. Training will be provided to employees on an annual basis at a minimum. Document all training in Appendix E. 6. MONITORING AND REPORTING Each of the previously identified drainage basins have their own outfall points where the basin discharges to surface waters, also known as the stormwater discharge outfall (SDO). Refer to Figure 2 for a map of the drainage basins and associated SDOs. Per NCG190 requirements, a monitoring program shall be established for conducting both analytical and qualitative monitoring from the three (3) industrial drainage areas. Both analytical and qualitative monitoring will be conducted twice per year; once from January— June and once from July -December with a minimum of 60 days separating monitoring events. Sample collection shall take place during a measureable storm event at each SDO from drainage areas with industrial practices.

If no discharge occurs during any sampling period, document "No Flow" on the DMR. Maintain a copy of all analytical results and DMRs in Appendix F. 6.2 QUALITATIVE MONITORING Qualitative monitoring is subjective and provides a quick, inexpensive way to evaluate sources of stormwater pollution by conducting a visual inspection. Qualitative monitoring will be conducted by a SPPT member at the same SDOs which require analytical monitoring. Qualitative monitoring can be conducted at the same time analytical samples are being collected and should be visually inspected for the following characteristics: ■ Color ■ Odor ■ Clarity ■ Floating Solids • Suspended Solids ■ Foam ■ Oil Sheen ■ Erosion or deposition at the outfall ■ Other obvious indicators of stormwater pollution Document visual inspection on the SDO Qualitative Monitoring Report included in Appendix G. A copy of the State guidance document, SDO Qualitative Monitoring Report Supplement SWU- 242a: Guidance for Rating Stormwater Discharge, has been included in Appendix G for reference. Any instances that stormwater contamination is present shall be investigated for potential cause(s). If a potential cause can be identified, Dudley's Marina shall evaluate the feasibility of corrective actions and implementation of those corrective actions within 60 days. All findings from these investigations shall be documented and maintained in the SPPP. 13 of 14 0 6.3 NON-STORMWATER DISCHARGES 1 In addition to the analytical and qualitative monitoring, all SDOs will be evaluated for the presence of non-stormwater discharges. At least annually, an SPPT member will visually inspect each SDO, during a dry weather period, for any flows. Dudley's Marina is not permitted for any other discharges, therefore there should not be flow from any SDO during dry weather. If non- stormwater discharges are observed, the SPPT member must investigate to determine the source. Complete the Non-Stormwater Discharge Certification after each annual evaluation and maintain a signed copy in Appendix H for the life of the permit. 6.4 MONITORING, REPORTING AND RECORDKEEPING A copy of all analytical monitoring results and monitoring event documentation, to include submitted DMRs, shall be maintained in Appendix F for the life of the permit. Qualitative monitoring documentation shall be maintained in Appendix G. Reporting and recordkeeping requirements for both analytical and qualitative monitoring are summarized below: Semi -Annual, Analytical Monitoring: o Complete a DMR (form SWU-253-060515) upon receipt of sampling results o Submit completed DMR to the state within 30 days from the date sampling results are received; o Complete a SDO Annual Summary DMR Report (form SWU-250NCG19- 060815) following the completion of both analytical sampling events per each calendar year; o Submit completed SDO Annual Summary DMR Report to the state o Maintain a copy of the laboratory sampling results, completed chain of custody forms and submitted DMRs in Appendix F. Semi -Annual, Qualitative Monitoring: o Complete a SDO Qualitative Monitoring Report (form SWU-242) for each evaluated outfall; o Maintain a copy of all SDO Qualitative Monitoring Reports in Appendix G; o Qualitative monitoring results should only be submitted to the State when specifically requested. 14 of 14 Permit No. NCG190000 STATE OF NORTH CAROLINA • DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES DIVISION OF ENERGY, MINERAL, AND LAND RESOURCES GENERAL PERMIT NO, NCG190000 TO DISCHARGE STORMWATER UNDER THE NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM For establishments primarily engaged in: Marinas In compliance with the provision of North Carolina General Statute 143-215.1, other lawful standards and regulations promulgated and adopted by the North Carolina Environmental Management Commission and the Federal Water Pollution Control Act, as amended, this permit is hereby issued to all owners or operators, hereafter permittees, which are covered by this permit as evidenced by receipt of a Certificate of Coverage by the Environmental Management Commission to allow the discharge of stormwater to the surface waters of North Carolina or separate storm sewer systems conveying stormwater to surface waters in accordance with the terms and conditions set forth herein.

The NOI shall be submitted and a certificate of coverage issued prior to any discharge of stormwater associated with industrial activity that has a point source discharge to the surface waters of the state. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit should be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has expired or has been revoked. Any person conducting an activity covered by an individual permit but which could be covered by this General Permit may request that the individual permit be revoked and coverage under this General Permit be provided. If industrial materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion from permitting must submit a No Exposure Certification N01 form to the Division; must receive • approval by the Division; must maintain no exposure conditions unless authorized to discharge under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater discharges is established. A TMDL sets a pollutant -loading limit that affects a watershed, or portion of a watershed, draining to an impaired water. For stormwater discharges to watersheds affected by a TMDL, coverage under this permit may depend on the facility demonstrating it does not have reasonable potential to violate applicable water quality standards for those pollutants as a result of discharges. If the Division determines that discharges have reasonable potential to cause water quality standard violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this General Permit. Once that individual permit is effective, the facility will no longer have coverage under this General Permit. Note that the permittee must identify impaired waters (scheduled for TMDL development) and waters already subject to a TMDL in the Site Overview, as outlined in the Stormwater Pollution Prevention Plan (SPPP), Part II, Section A.1. A list of approved TMDLs for the state of North Carolina can be found at hip: / /nortal.ncdenr.org f web f wa /us /mtu/tmdl. • Part I Page 1 of 2 . SECTION B: PERMITTED ACTIVITIES LJ • Permit No. NCG190000 Until this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater to the surface waters of North Carolina or separate storm sewer system which has been treated and managed in accordance with the terms and conditions of this General Permit and the requirements of the permittee's Certificate of Coverage (COC). The permittee's COC is hereby incorporated by reference into this General Permit. Any violation of the COC is a violation of this General Permit and subject to enforcement action as provided in the General 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 permit, authorization, or approval. The stormwater discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. This General Permit does not authorize discharges determined by the Division to be wastewaters. 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. Part I Page 2 of 2 Permit No. NCG190000 PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED • DISCHARGES SECTION A: STORMWATER POLLUTION PREVENTION PLAN The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP is public information in accordance with Part III, Section E, paragraph 3 of this permit. The SPPP shall include, at a minimum, the following items: 1. Site Overview. The Site Overview shall provide a description of the physical facility and the potential pollutant sources that may be expected to contribute to contamination of stormwater discharges. The Site Overview shall contain the following: (a) A general location map (USGS quadrangle map or appropriately drafted equivalent map), showing the facility's location in relation to transportation routes and surface waters; the name of the receiving waters to which the stormwater outfalls discharge, or if the discharge is to a municipal separate storm sewer system, the name of the municipality and the ultimate receiving waters; and latitude and longitude of the points of stormwater discharge associated with industrial activity. The general location map (or alternatively the site map) shall identify whether any receiving waters are impaired (on the state's 303(d) list of impaired waters) or if the site is located in a watershed for which a TMDL has been established, and what the parameters of concern are. (b) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. A narrative description of the potential pollutants that could be expected to be present in the stormwater discharge from each outfall. (c) A site map drawn at a scale sufficient to clearly depict: the site property boundary; the stormwater discharge outfalls; all on-site and adjacent surface waters and wetlands; industrial activity areas (including storage of materials, disposal areas, process areas, loading and unloading areas, and haul roads); site topography, all drainage features and structures; drainage area boundaries and total contributing area for each outfall; direction of flow in each drainage area; industrial activities occurring in each drainage area; buildings; stormwater Best Management Practices (BMPs); and impervious surfaces. The site map must indicate the percentage of each drainage area that is impervious, and the site map must include a graphic scale indication and north arrow. In addition, the following industrial activity areas must also be identified on the site map: fueling, engine maintenance and repair, vessel maintenance and repair, washing, painting, sanding, blasting, welding, and metal fabrication. (d) A list of significant spills or leaks of pollutants during the previous three (3) years and any corrective actions taken to mitigate spill impacts. (e) Certification that the stormwater outfalls have been evaluated for the presence of non- stormwater discharges. The permittee shall re -certify annually that the stormwater • outfalls have been evaluated for the presence of non-stormwater discharges. If non- stormwater discharges are present, the permittee shall identify the source and record whether Part II Page 1 of 10 Permit No. NCG 190000 • the discharge is otherwise permitted (by rule or a different permit). The permittee shall evaluate the environmental significance of the non-stormwater discharges and include a summary written record with the certification. The certification statement and summary written record shall be retained with the SPPP, and shall be dated and signed in accordance with the requirements found in Part III, Section B, paragraph 5. 2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a narrative description of the materials management practices employed which control or minimize the stormwater exposure of significant materials, including structural and nonstructural measures. The Stormwater Management Strategy, at a minimum, shall incorporate the following: (a) Feasibility Study. A review of the technical and economic feasibility of changing the methods of operations and/or storage practices to eliminate or reduce exposure of materials and processes to rainfall and runoff flows. Wherever practical, the permittee shall prevent exposure of all storage areas, material handling operations, and manufacturing or fueling operations. In areas where elimination of exposure is not practical, this review shall document the feasibility of diverting the stormwater runoff away from areas of potential contamination. (b) Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage of liquid materials including petroleum products; storage in any amount of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals: and storage in any amount of hazardous substances. in • order to prevent leaks and spills from contaminating stormwater runoff. A table or summary of all such tanks and stored materials and their associated secondary containment areas shall be maintained. If the secondary containment devices are connected to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices, which shall be secured closed with a locking mechanism. Any stormwater that accumulates in the containment area shall beat a minimum visually observed for color, foam, outfall staining, visible sheens, and dry weather flow, prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated by any material. Records documenting the individual making the observation, the description of the accumulated stormwater, and the date and time of the release shall be kept for a period of five (5) years. For the purposes of effective stormwater pollution prevention the SPPP is intended to be broader and more comprehensive than a federal oil Spill Prevention, Control, and Countermeasure Plan (SPCC). For facilities subject to a federal SPCC plan, any portion of the federal SPCC plan fully compliant with the requirements of this permit may be used to demonstrate compliance with this permit. (c) BMP Summary. A listing of site structural and non-structural Best Management Practices (BMPs) shall be provided. The installation and implementation of BMPs shall be based on the assessment of the potential for sources to contribute significant quantities of pollutants to stormwater discharges and on data collected through monitoring of stormwater discharges. The BMP Summary shall include a written record of the specific rationale for installation and implementation of the selected site BMPs. The BMP Summary shall be reviewed and updated annually. 3. Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and dated by each individual Part II Page 2 of 10 Permit No. NCG190000 acknowledging their responsibilities for the procedures. A responsible person shall be on-site • at all times during facility operations that have increased potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be incorporated by reference into the SPRP. 4. Solvent Management Plan. The Solvent Management Plan shall be incorporated as a separate chapter into the Stormwater Pollution Prevention Plan (SPPP). The Solvent Management Plan shall include an annually updated and quantified inventory of the solvents present on site during the previous three years; a narrative description of the facility locations and uses of the solvents, the method of disposal including quantities disposed on-site and off-site; and the management procedures and engineering measures for assuring that solvents do not spill or leak into stormwater. If solvents are not stored or used onsite, then the owner must certify that in the SPPP. DEMLR may at its discretion require submittal, review, and approval of the Solvent Management Plan. The discharger shall include the following signed certification statement on each discharge monitoring report: "Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit requirement for managing solvents, I certify that to the best of my knowledge and belief, no leak, spill, or dumping of concentrated solvents into the stormwater or onto areas which are exposed to rainfall or stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing all the provisions of the Solvent Management Plan included in the Stormwater Pollution Prevention Plan." Preventative Maintenance and Good Housekeeping Program. A preventative maintenance • and good housekeeping program shall be developed and implemented. The program shall address all stormwater control systems (if applicable), stormwater discharge outfalls, all on-site and adjacent surface waters and wetlands, industrial activity areas (including material storage areas, material handling areas, disposal areas, process areas, loading and unloading areas, and haul roads), all drainage features and structures, and existing structural BMPs. The program shall establish schedules of inspections, maintenance, and housekeeping activities of stormwater control systems, as well as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or stormwater pollution where not already addressed under another element of the SPPP. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. Timely compliance with the established schedules for inspections, maintenance, and housekeeping shall be recorded and maintained in the SPPP. 6. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi- annual schedule, once during the first half of the year (January to June), and once during the second half (July to December), with at least 60 days separating inspection dates (unless performed more frequently than semi-annually). These facility inspections are different from, and in addition to, the stormwater discharge characteristic monitoring at the outfalls required in Part II B, C, and D of this permit. 7. Employee Training. Training programs shall be developed and training provided at a minimum on an annual basis for facility personnel with responsibilities for: spill response and cleanup, preventative maintenance activities, and for any of the facility's operations that have the potential to contaminate stormwater runoff. The annual training shall be documented by the signature and printed or typed name of each employee trained. Additional required training items include: used oil management, spent solvent management, disposal of spent Part II Page 3 of 10 Permit No. NCG190000 • abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting procedures, and used battery management. 8. Responsible Party. The SPPP shall identify a specific position or positions responsible for the overall coordination, development, implementation, and revision of the SPPP. Responsibilities for all components of the SPPP shall be documented and position assignments provided. 9. SPPP Amendment and Annual Update. All aspects of the SPPP shall be reviewed on an annual basis. The permittee shall amend the SPPP whenever there is a change in design, construction, operation, site drainage, maintenance, or configuration of the physical features which may have a significant effect on the potential for the discharge of pollutants to surface waters. The annual update shall include at a minimum: (a) an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the notation that no spills have occurred (element of the Site Overview); (b) a written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges (element of the Site Overview); (c) a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP Summary element of the Stormwater Management Strategy). (d) a review and comparison of sample analytical data to benchmark values (if applicable) over the past year, including a discussion about Tiered Response status. The permittee shall use the Division's Annual Summary Data Monitoring Report (DMR) form, available from the Stormwater Permitting Program's website (See'Monitoring Forms' here: httl2:1112ortal.ncdenr.org/web/ir/npdes-stormwater). • The Director may notify the permittee when the SPPP does not meet one or more of the minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the SPPP to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part III, Section B, Paragraph S) to the Director that the changes have been made. C-1 10. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan and all appropriate BMPs consistent with the provisions of this permit, in order to control contaminants entering surface waters via stormwater. Implementation of the SPPP shall include documentation of all monitoring, measurements, inspections, maintenance activities, and training provided to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such documentation shall be kept on-site for a period of rave (S) years and made available to the Director or the Director's authorized representative immediately upon request. Part 11 Page 4 of 10 Permit No. NCG190000 SECTION B: ANALYTICAL MONITORING REQUIREMENTS Analytical monitoring of stormwater discharges shall be performed as specified in Table 1 at each stormwater discharge outfall (SDO).

If the facility is monitoring monthly because of Tier Two or Tier Three response actions under the previous General Permit, the facility shall continue a monthly monitoring and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this permit or the Division. 2 Grab samples shall be collected within the first 30 minutes of discharge. Where physical separation between outfalls prevents collecting all samples within the first 30 minutes, the permittee shall begin sampling within the first 30 minutes, and shall continue until completed. 3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be kept on site with the SPPP. 4 For each sampled measureable storm event, an on-site rain gauge reading must be recorded. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading may be substituted for an on-site reading. All analytical monitoring shall be performed during a measurable storm event. A measurable storm event is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72 -hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local DEMLR Regional Office. See Definitions. u Part II Page 5 of 10 Pages • Permit No. NCG190000 The permittee shall complete the analytical samplings in accordance with the schedule specified in Table 2. A minimum of 60 days must separate Period 1 and Period 2 sample dates unless monthly monitoring has been instituted under other requirements of this permit.

If at the expiration of the general permit, the permittee has submitted an application for renewal of coverage before the submittal deadline, the permittee will be considered for renewed coverage. The applicant must continue semi- annual monitoring until the renewed Certificate of Coverage is issued. 2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report indicating "No Flow' within 30 days of the end of the six-month sampling period. In all cases, the permittee shall report the analytical results from the first sample with valid results within the monitoring period. The permittee shall compare those results to the benchmark values in Table 3 or Table 4. Exceedances of benchmark values require the permittee to increase monitoring, increase management actions, increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered program.

An exceedance of a stormwater benchmark value is not a permit violation; however, failure to respond to the exceedances as outlined in this permit is a violation of permit conditions. The benchmarks are intended to reduce polluted discharges by triggering the permittee's required response actions under Tiers One, Two, and Three. See below the descriptions of Tiers One, Two, and Three response actions. Tier One If: The first valid sampling results are above a benchmark value for any parameter at any outfall; Then: The permittee shall: 1. Conduct a stormwater management inspection within two weeks of receiving the sample results. 2. Identify and evaluate possible causes of the benchmark value exceedance. 3. Identify potential, and select the specific feasible: source controls, operational controls, or physical improvements to reduce concentrations of the parameters of concern. 4. Implement the selected feasible actions within two months of the inspection. 5. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark exceedance, the inspection date, the personnel conducting the inspection, the selected feasible actions, and the date the selected feasible actions were implemented. 6. Note: Exceedances for a different parameter separately trigger the tiered response requirements. Part II Page 7 of 10 Pages • 1� u • • Permit No. NCG190000 Tier Two If: The first valid sampling results from two consecutive monitoring periods are above the benchmark values for anv specific parameter at a Then: The permittee shall: outfall: 1. Repeat all the required actions outlined above in Tier One. 2. Immediately institute monthly monitoring and reporting for all parameters at every outfall where a sampling result exceeded the benchmark value for two consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values. 3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly monitoring report indicating "No Flow" to comply with reporting requirements. 4. Alternatively, in lieu of steps 2 and 3, the permittee may exercise the option of contacting the DEMLR Regional Office Engineer as provided below in Tier Three. The Regional Office Engineer may direct the response actions on the part of the permittee as provided in Tier Three. The permittee will be considered to be obligated under the Tier Three provisions. 5. Maintain a record of the Tier Two response in the SPPP. 6. Continue Tier Two out the permit COC renewal Tier Three If the valid sampling results required for the permit monitoring periods exceed the benchmark value for any specific parameter at any specific outfall on four occasions, the permittee shall notify the DEMLR Regional Office Engineer in writing within 30 days of receipt of the fourth analytical results. DEMLR may but is not limited to: • require the permittee to revise, increase, or decrease the monitoring and reporting frequency for some or all parameters, including requiring sampling of additional or substitute parameters; • rescind coverage under the General Permit, and require that the permittee apply for an individual stormwater discharge permit; • require the permittee to install structural stormwater controls; • require the permittee to implement other stormwater control measures; • require the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters; • require the permittee implement site modifications to qualify for a No Exposure Exclusion; or • require the permittee to continue Tier Three obligations through the permit COC renewal process. Failure to monitor and report per the permit terms may result in the Division reauirin monthlv monitorine and reportine for all parameters for a specified time period. Lack of a discharge from an outfall for the monitoring period, or inability to collect a sample because of adverse weather conditions during a monitoring period will not constitute failure to monitor, as long as those conditions are reported on the monitoring period DMR and noted in the SPPP. (See Adverse Weather in Definitions.) Similarly, sampling is not required outside of the facilit-y s normal operating hours. However, if a facility is inactive for an extended period of time, the permittee must request, and obtain, dormant site status from the DEMLR Regional Engineer in order to be excused from sampling during the dormant period. The DEMLR letter granting dormant status must be kept with the SPPP, and available for inspection. Part II Page 8 of 10 Pages Permit No. NCG190000 In the event that the Division releases the permittee from continued monthly monitoring and reporting under Tier Two or Tier Three, DEMLR's release letter may remain in effect through subsequent reissuance of this permit, unless the release letter provides for other conditions or duration. The permittee must report all results from all valid discharge samples taken during each monitoring period. However, for purposes of benchmark comparison and Tiered response actions, the permittee shall use the analytical results from the first sample with valid results within the monitoring period. SECTION C: QUALITATIVE MONITORING REQUIREMENTS The purpose of qualitative monitoring is to implement a quick and inexpensive way to evaluate the effectiveness of the permittee's SPPP and to identify the potential for new sources of stormwater pollution. Qualitative monitoring of stormwater discharge outfalls must be performed during a measurable storm event. Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of representative outfall status. Qualitative monitoring shall be performed as specified in Table 5 with each required analytical monitoring event: whether semi-annual or more frequently as may be subsequently required under Tier Two, Tier Three, or per the Qualitative Monitoring Response requirements below. Inability to monitor because of adverse weather or lack of discharge during the monitoring period must be documented in the SPPP and recorded on the Qualitative Monitoring Report (see Adverse Weather in Definitions). Only stormwater discharge outfalls (SDOs) discharging stormwater associated with industrial activity must be monitored (See Definitions). In the event an atypical condition is noted at an SDOs, the permittee shall document the suspected cause of the condition and any actions taken in response to the discovery. This documentation will be maintained with the SPPP.

Monitoring Frequency: Twice per year (unless other provisions of this permit prompt other frequency) during a measureable storm event. See Table 2 for schedule of monitoring periods. The permittee must continue qualitative monitoring throughout the permit renewal process. 2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall (SDO) associated with industrial activity, regardless of representative outfall status (ROS). A minimum of 60 days must separate monitoring dates, unless additional sampling has been instituted as part of other analytical monitoring requirements in this permit. If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement those corrective actions within 60 days, per the Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation, and response actions shall be kept in the SPPP. �.: -art �xrx s`sa-a�< �,� lld tlt Ver' Ot oi'II ' a f * �5 � J 3 Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying the potential for new sources of stormwater pollution, and prompting the permittee's response to pollution. If the permittee repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if the discharge causes or contributes to a water quality standard violation, DEMLR may but is not limited to: • require that the permittee revise, increase, or decrease the monitoring frequency for some or all parameters (analytical or qualitative); • require the permittee to install structural stormwater controls; • require the permittee to implement other stormwater control measures; • require the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters; or • require the permittee implement site modifications to qualify for a No Exposure Exclusion.

Certificate of Coverage Actions Coverage under the general permit may be modified, revoked and reissued, or terminated for cause. The notification of planned changes or anticipated noncompliance does not stay any general permit condition [40 CFR 122.41(f)]. Annual Administering and Compliance Monitoring Fee Requirements The permittee must pay the administering and compliance monitoring fee within 30 (thirty) days after being billed by the Division. Failure to pay the fee in timely manner in accordance with 15A NCAC 2H .0105(b)(2) may cause this Division to initiate action to revoke coverage under the general permit. SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS 1. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve • compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of this permit [40 CFR 122.41(e)]. r, u Need to Halt or Reduce Not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this general permit [40 CFR 122.41(c)]. Bypassing of Stormwater Control Facilities Bypass is prohibited and the Director may take enforcement action against a permittee for bypass unless: a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention of stormwater, or maintenance during normal periods of equipment downtime or dry weather. This condition is not satisfied if adequate backup controls should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and c. The permittee submitted notices as required under, Part III, Section E of this general permit. If the Director determines that it will meet the three conditions listed above, the Director may approve an anticipated bypass after considering its adverse effects. Part III Page 6 of 10 Pages Permit No. NCG 190000 SECTION D: MONITORING AND RECORDS Representative Sampling Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Analytical sampling shall be performed during a measureable storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. Monitoring points as specified in this general permit shall not be changed without notification to and approval of the Permit Issuing Authority [40 CFR 122.41(j)]. 2. Recording Results For each measurement or sample taken pursuant to the requirements of this general permit, the permittee shall record the following information [40 CFR 122.41]: a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling or measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. Flow Measurements Where required, appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. 4. Test Procedures Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136. To meet the intent of the monitoring required by this general permit, all test procedures must produce minimum detection and reporting levels and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below general permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. Representative Outfall If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater discharges are substantially identical and the permittee is granted representative outfall status, then analytical sampling requirements may be performed at a reduced number of outfalls. Records Retention Visual monitoring shall be documented and records maintained at the facility along with the Stormwater Pollution Prevention Plan (SPPP). Copies of analytical monitoring results shall also be maintained on-site. The permittee shall retain records of all monitoring information, including Part III Page 7 of 10 Pages • • • Permit No. NCG190000 • o all calibration and maintenance records, o all original strip chart recordings for continuous monitoring instrumentation, o copies of all reports required by this general permit, including Discharge Monitoring Reports (DMRs) and eDMR or other electronic DMR report submissions. o copies of all data used to complete the Notice of Intent to be covered by this general permit. These records or copies shall be maintained for a period of at least 5 years from the date of the sample, measurement, report or Notice of Intent (NOI) application. This period may be extended by request of the Director at any time [40 CFR 122.411. Inspection and Entry The permittee shall allow the Director, or an authorized representative (including an authorized contractor acting as a representative of the Director), or in the case of a facility which discharges through a municipal separate storm sewer system, an authorized representative of a municipal operator or the separate storm sewer system receiving the discharge, upon the presentation of credentials and other documents as may be required by law, to: a. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this general permit; b. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this general permit; C. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and d. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as • otherwise authorized by the Clean Water Act, any substances or parameters at any location [40 CFR 122.41(i)]. • SECTION E: REPORTING REQUIREMENTS Discharge Monitoring Rem Samples analyzed in accordance with the terms of this general permit shall be submitted to the Division on Discharge Monitoring Report (DMR) forms provided by the Director or submitted electronically to the appropriate authority using an approved electronic DMR reporting system (e.g., eDMR). DMR forms are available on the Division's website (httR//nortal.ncdenr.org/web jlr/npdes-stormwater#tab-3). Regardless of the submission method (paper or electronic), submittals shall be delivered to the Division, or appropriate authority, no later than 30 days from the date the facility receives the sampling results from the laboratory. When no discharge has occurred from the facility during the report period, the permittee is required to submit a discharge monitoring report, within 30 days of the end of the specified sampling period, giving all required information and indicating "NO FLOW" as per NCAC T15A 0213.0506. If the permittee monitors any pollutant more frequently than required by this general permit using test procedures approved under 40 CFR Part 136 and at a sampling location specified in this general permit or other appropriate instrument governing the discharge, the results of such monitoring shall be included in the data submitted on the DMR. Part III Page 8 of 10 Pages Permit No. NCG190000 The permittee shall record the required qualitative monitoring observations on the SDO Qualitative • Monitoring Report form provided by the Division and shall retain the completed forms on site. Qualitative monitoring results should not be submitted to the Division, except upon DEMLR's specific requirement to do so. Qualitative Monitoring Report forms are available at the website above. 2. Submitting Reports Two signed copies of Discharge Monitoring Reports (DMRs) shall be submitted to: Central Files Division of Water Resources 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Visual monitoring results should not be submitted to the Division unless specifically requested. Blank DMR forms, Annual Summary DMR forms, and visual monitoring forms are available at the website of the Division's Stormwater Permitting Program: htW:Ilportal.ncdenr.org/webilrinl2des-stormwater The Permit Issuing Authority may require the permittee to begin reporting monitoring data electronically during the term of this permit The permittee may be required to use North Carolina's eDMR internet application for that purpose. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be • required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the address above. 3. Availability of Reports Except for data determined to be confidential under NCGS 143-215.3(a)(2) or Section 308 of the Federal Act, 33 USC 1318, all reports prepared in accordance with the terms shall be available for public inspection at the offices of the Division. As required by the Act, analytical data shall not be considered confidential. Knowingly making any false statement on any such report may result in the imposition of criminal penalties as provided for in NCGS 143-215.6B or in Section 309 of the Federal Act 4. Non-Stormwater Discharges If the storm event monitored in accordance with this general permit coincides with a non- stormwater discharge, the permittee shall separately monitor all parameters as required under all other applicable discharge permits and provide this information with the stormwater discharge monitoring report. S. Planned Changes The permittee shall give notice to the Director as soon as possible of any planned changes at the permitted facility which could significantly alter the nature or quantity of pollutants discharged [40 CFR 122.41(1)]. This notification requirement includes pollutants which are not specifically listed in the general permit or subject to notification requirements under 40 CFR Part 122.42 (a). • Part III Page 9 of 10 Pages • Permit No. NCG190000 6.

Permit No. NCG190000 Adverse Weather Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local flooding, high winds, or electrical storms, or situations that otherwise make sampling impractical. When adverse weather conditions prevent the collection of samples during the sample period, the permittee must take a substitute sample or perform a visual assessment during the next qualifying storm event. Documentation of an adverse event (with date, time and written narrative) and the rationale must be included with your SPPP records. Adverse weather does not exempt the permittee from having to file a monitoring report in accordance with the sampling schedule. Adverse events and failures to monitor must also be explained and reported on the relevant DMR. 3. Allowable Non-Stormwater Discharges This general permit regulates stormwater discharges. Non-stormwater discharges which shall be allowed in the stormwater conveyance system include: a. All other discharges that are authorized by a non-stormwater NPDES permit. b.

Part IV Page 4 of 4 Pages North Carolina Department of Environment and Natural Resources Technical Bulletin for N.C. General Stormwater Permit N CG 190000 Technical Bulletin for NCG 190000 Revised 6/04/2015 What activities are covered by this general permit? N_CG190000 allows stormwater discharges associated with activities classified as establishments primarily en- gaged in: Operating Marinas [standard industrial classification (SIC) 4493] that provide vehicle maintenance activities, and Ship and Boat Building and Repairing [SIC 373]; and like activities deemed by the Division of Energy, Mineral, and Land Resources (DEMLR) to be similar in the process and/or the exposure of raw materials, products, by-products, or waste materials. • This general permit does not authorize discharges at the facility containing waste streams including, but not lim- ited to, bilge and ballast water, cooling water, sanitary wastes, power and hand washing, blasting, sanding, and fish cleaning stations. A separate wastewater permit may be required for these and other similar wastewater dis- charges. What are the key permit requirements? • Implement a Stormwater Pollution Prevention Plan (SPPP) (Part II, Section A). • Provide secondary containment for all bulk storage of liquid materials (Part Il, Section A, 2.(b)). • Perform, document, and report analytical and qualitative monitoring during a measurable storm event twice each year. At the same time perform and document visual monitoring twice each year (Part II, Section B & Q. What has changed since the last renewal? • Made it easier to sample during a measureable storm event (new term), rather than a representative storm event (previous permit) (Part IV Definitions). • Replaced Oil and Grease with a more specific Non -polar Oil & Grease test with a lower benchmark of 15 mg/L. • Twice -per -year monitoring of pH is no longer required. • Refinements and clarifications to the SPPP requirements (refer to Part II, Section A). • The permit allows forgoing sampling if adverse weather conditions prevent collection (Part IV Definitions). • Permittee is not required to obtain runoff samples outside of normal operating hours. • A lower TSS benchmark of 50 mg/L for stormwater discharges into especially protected waters. • New provisions for e -reporting (eDMR), once DEMLR capabilities for eDMR are established. What are BMPs and why are they important? A facility's Stormwater Pollution Prevention Plan should include Best Management Practices (BMPs) to control the discharge of pollutants from all stormwater outfalls. BMPs include a variety of measures that help minimize the potential for pollutants to enter stormwater that drains from a facility. There are different types of BMPs: Non-structural (practices or activities) BMPs include: • Eliminating exposure of materials and equipment whenever possible by moving them to indoor locations. • Practicing good housekeeping on-site. Handle and store materials at the facility in an orderly fashion. • Exchanging hazardous materials for non -hazardous ones wherever possible. • Establishing routine leak and maintenance checks to minimize any chance of spills occurring. Clean up all spills immediately. • Establishing bulk storage tank protocols that minimize the risk of spills during loading and unloading. • Maintaining wash pads and keeping them clear of paint chips, debris, and particles. Structural (equipment or devices) BMPs include: • Containment dikes around the loading areas of bulk liquid storage containers. • Roofs and secondary containment around materials so that they are not exposed to stormwater. • Collection systems around boat wash areas to direct wash water to a holding tank or sanitary sewer. • Converting from a liquid operation to a dry operation for hull maintenance and cleaning. • Collection of debris from paint chips in boat maintenance areas to minimize contamination of stormwater. • Hull maintenance practices that are performed on dry land as far awav from the water as possible. is r� PAGE TECHNICAL BULLETIN FOR N.C. GENERAL STORMWATER REVISED 6/04/2015 Frequently Asked Questions Could I be exempt from a NPDES stormwater permit? Possibly. Facilities with industrial activities subject to NPDES storm - water regulations that eliminate all potential stormwater exposure may be eligible for a No Exposure Exclusion from a permit. Facili- ties that meet this condition may apply by submitting a No Exposure Certification application (see link below). Facilities must re -certify "No Exposure" status every five years. What if I sell my business, or the name changes? This is a minor modification that requires approval of DEMLR's di- rector before a permittee is ab- solved of responsibility for the per- mit. To request this change, com- plete and submit a Name/ Ownership Change Form SWU- 239. Do I have to monitor all the outfalls? Yes. However, you may request Representative Outfall Status (ROS). If approved, this status allows analytical monitoring at fewer outfalls. To make this re- quest, submit a ROS Request Form. Does a certified lab need to analyze my samples? Monitoring under NPDES per- mits must be conducted in accord- ance with test procedures ap- proved in federal regulations in 40 CFR § 136. All labs certified by North Carolina perform analysis in accordance with those proce- dures. While N.C. certification requirements do not apply to test- ing stormwater-only discharges, data gathered under an NPDES permit must still conform to fed- eral reouirements. Using a North Carolina certified lab is one way to ensure compliance. A list of certified labs is available from: http://portal.ncdenr.org/web/wq/ lab/cert/cerlablists Can my boat wash water be discharged to or with my stormwater? No. Boat wash water, whether from hand washing or power wash- ing, is considered wastewater. This stormwater permit does not authorize wastewater discharges. Wastewater is not allowed to mix, or be "diluted", with stormwater for discharge at a stormwater out- let unless permitted by a separate wastewater permit. Once storm - water commingles with wastewater, it is all considered wastewater and must be handled as such. A separate wastewater permit is required in order to dis- charge wastewater. Some possi- ble alternatives (which may re- quire an additional separate per- mit) for minimizing wastewater discharge to surface waters in- clude: discharge to a municipal wastewater treatment plant, water recycling, conversion of activities to dry processes which allow for easy clean-up and maintenance and proper disposal of waste gen- erated from industrial activities. The NCG190000 permit is applica- ble to a marina that offers vehicle maintenance service, which in- cludes boat cleaning. It is not ap- plicable for an individual washing their own boat at a marina. How- ever, it is highly encouraged that facilities educate and monitor the use of appropriate BMPs by boat owners when washing their boats to minimize potential impacts to surface water. Who inspects my site, and for what? DEMLR regional office staff may visit the site to see if you have the permit, an acceptable SPPP, and that you are following your SPPP. These inspections may be routine or they may be the result of public complaints. Please take compliance seriously! Facilities that violate stormwater permit conditions may be subject to fines. Civil penalties of up to $25,000 per day may be assessed for each violation.
