Such discharges shall be controlled, limited and monitored as specified below. 1. Stormwater Pollution Prevention Plan The Pernttee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the Plan. This Plan shall be considered public information in accordance with Part 11, Standard Conditions, Section E.8. of this permit. The Plan shall include, at a minimum, the following items: a. Site Plan. The site plan shall provide a description of the physical facility and the potential pollutant sources which may be expected to contribute to contamination of stormwater discharges. The site plan shall contain the following: . (1) A general location map (USGS quadrangle map or appropriately drafted equivalent map), showing the facility's Iocation in relation to transportation routes and surface waters, the name of the receiving water(s) to which the stormwater outfall(s) discharges, or if the discharge is to a municipal separate storm sewer system; the name of the municipality and the ultimate receiving waters; and accurate latitude and longitude of the point(s) of discharge. (2} A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. (3) A site map drawn to scale with the distance legend indicating location of industrial activities (including storage of materials, disposal areas, process areas and loading and unloading areas), drainage structures, drainage areas for each outfall and activities occurring in the drainage area, building locations and impervious surfaces, and the percentage of each drainage area that is impervious. For each outfall, a narrative description of the potential pollutants which could be expected to be present in the stormwater discharge. (4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3 previous years and any corrective actions taken to mitigate spill impacts. (5) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges. The certification statement will be signed in accordance with the requirements found in Part I1, Standard Conditions, Section B. 9. Page 4 Permit No. NCS000334 b. Stormwater Management Plan. The stormwater management plan shall contain a narrative description of the materials management practices employed which control or minimize the exposure of significant materials to stormwater, including structural and nonstructural measures. The stormwater management plan, at a minimum, shall incorporate the following: (1) A study addressing 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 stormwater. Wherever practicable the permittee shall cover all storage areas, material handling operations, manufacturing or fueling operations to prevent materials exposure to stormwater. In areas where elimination of exposure is not practicable, the stormwater management plan shall document the feasibility of diverting the stormwater runoff away from areas of potential contamination. (2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of hazardous materials to prevent leaks and spills from contaminating stormwater runoff. If the secondary containment devices are connected directly to stormwater conveyance systems, the connection shall be controlled by manually activated valves or other similar devices [which shall be secured with a locking mechanism] and any stormwater that accumulates in the containment area shall be at a minimum visually observed for color, foam, and visible sheens, prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated. 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 years. (3) A narrative description shall be provided of Best Management Practices (BMPs) to be considered such as, but not limited to, oil and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or retention, where necessary. The need for structural BMPs shall be based on the assessment of potential of sources to contribute significant quantities of pollutants to stormwater discharges and data collected through monitoring of stormwater discharges. (4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit or prevent erosion associated with the stormwater systems. C. Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall incorporate a risk assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or team) responsible for implementing the plan shall be identified in the plan. A responsible person shall be on -site at all times during facility operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated with the facility operations. d . Preventative Maintenance and Good Housekeeping Program. A preventative maintenance program shall be developed. The program shall document schedules of inspections and maintenance activities of stormwater control systems, plant equipment and systems. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. e. Employee Training. Training schedules shall be developed and training provided at a minimum on an annual basis on proper spill response and cleanup procedures and preventative maintenance activities for all personnel involved in any of the facility's Page 5 Permit No. NCS000334 operations that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the training shall be identified in the Plan. f. Responsible Party.

Such documentation shall be kept on -site for a period of five years and made available to the Director or his authorized representative immediately upon request. 2. Minimum Monitoring and Reporting Requirements Minimum monitoring and reporting requirements are as follows unless otherwise approved in writing by the Director of the Division of Environmental Management. a. 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 sampling requirements may be performed at a reduced number of outfalls. b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry weather flow shall be performed at all stormwater discharge outfall locations. All visual monitoring shall be documented and records maintained with the Stormwater Pollution Prevention Plan. The initial visual monitoring event shall be performed simultaneously Page 6 Permit No. NCS000334 with the first analytical monitoring event and documentation of only this initial visual monitoring event shall be submitted along with the required analytical monitoring submittal. C. For purposes of the stormwater sampling required in this permit, all samples shall be collected from a discharge resulting from a representative storm event (See Part II, Standard Conditions, Section A). Failure to monitor storm events in accordance with the specified frequency shall constitute a violation of this permit. If the stormwater runoff is controlled by a detention pond, the following sampling requirements shall apply: (1) If the detention pond detains the runoff generated by one inch of rainfall for 24 hours, visual observations for color, foam, outfall staining, visible sheens, and dry weather flow are required, but analytical sampling shall not be required. (2) If the detention pond discharges only in response to a storm event exceeding a 25- year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall be considered a non -discharging stormwater control system and not subject to NPDES requirements, unless the discharge causes a violation of water quality standards. d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms provided by the Director no later than January 31 for the previous year in which sampling was required to be performed. e. Analytical results from sampling during the final year of the permit term shall be submitted with the permit renewal application. f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be allowed in the stormwater conveyance system are: (1) All other discharges that are authorized by a non-stormwater NPDES permit. (2) Uncontaminated groundwater, foundation drains, air -conditioner condensate without added chemicals, springs, discharges of uncontaminated potable water, waterline and fire hydrant flushings, water from footing drains, flows from riparian habitats and wetlands. (3) Discharges resulting from fire -fighting. If the storm event monitored and reported in accordance with this permit coincides with a non-stormwater discharge, the permittee shall separately monitor and report all parameters as required under the non-stormwater discharge permit and provide this information with the stormwater discharge monitoring report. Page 7 Permit No. NCS000334 g. Specific Stormwater Monitoring Requirements The specific stormwater monitoring requirements includes both analytical and visual monitoring of stormwater samples. Specific monitoring requirements are defined below. (1) Analytical Monitoring Proposed facilities are required to perform sampling and analyses of the parameters prescribed in the Form 2F one time during the first two years of operation of the facility. Based upon review of the data from the operating facility, the Division may amend the monitoring requirements of this permit. (2) Visual Monitoring Visual monitoring requires a qualitative visual inspection of each stormwater outfall, regardless of representative outfall status, for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SWPPP) and assessing new sources of stormwater pollution. No analytical tests are required. Visual monitoring of stormwater outfalls does not need to be performed during a representative storm event.

Total Precipitation and duration of the rainfall event measured shall result from the sampled representative storm event. 5 Total recoverable lead monitoring is required only at facilities where fueling occurs. 6 Detergent monitoring is required only at facilities which conduct vehicle cleaning operations. Page 9 Permit No. NCS000334 (4) Cut-off Concentrations for Vehicle Maintenance Activities The arithmetic mean of all analytical sampling results collected during the term of the permit shall be calculated for each parameter and compared to the cut-off concentrations listed below. If the arithmetic mean meets the specified cut-off concentration condition for a given parameter, then the facility is not required to continue annual analytical monitoring for that parameter during the term of the permit unless a significant change in facility operations or configuration occurs. If a cut-off concentration results in discontinued analytical monitoring, the permittee is required to maintain facility operations that ensure the continuation of stormwater runoff quality. The permittee must perform analytical sampling during the first and last year of the permit term regardless of cut-off concentration conditions. Analytical results from sampling during the final year of the permit term must be submitted with the permit renewal application. Stormwater Discharge Characteristics Cut-off Concentration HI within range 6.0 - 9.0 s.u. Oil and Grease < 30 m Lead, Total Recoverable < 0.033 m Total Suspended Solids < 100 m Detergents (MBAS) < 0.50 m Footnotes: 1 pH cannot be averaged due to the nature of the logarithmic pH scale. The most recent pH sample result shall be used for cut-off concentration purposes. Page 10 Permit No. NCS000334 SECTION B: SCHEDULE OF COMPLIANCE 1.
