Such discharge will be controlled, limited and monitored in accordance with the permittee's Comprehensive Stormwater Management Program Report, herein referred to as the Stormwater Management Plan (SWMP). The SWMP includes components of the permittee's NPDES Stormwater Permit Application, NPDES Stormwater Permit Application Comprehensive Stormwater Management Program Report and any approved modifications, and the permittee's industrial stormwater control plan. The requirements in this permit apply to stormwater discharges associated with industrial activity from Air Transportation facilities identified by the SIC Codes in Major Group 45, namely air transportation, scheduled, and air courier (SIC 4512 and 4513); air transportation, non scheduled (SIC 4522); airports, flying fields, except those maintained by aviation clubs, and airport terminal services including: air traffic control, except government; aircraft storage at airports; aircraft upholstery repair; airfreight handling at airports; airport hangar rental; airport leasing, if operating airport; airport terminal services; and hangar operations; and airport and aircraft service and maintenance including: aircraft cleaning and janitorial service; aircraft servicing/repairing, except on a factory basis; vehicle maintenance shops; material handling facilities; equipment clearing operations; and airport and aircraft deicing/anti-icing. (SIC 4581) The types of activities that Air Transportation facilities are primarily engaged in are: (a) Servicing, repairing, or maintaining aircraft and ground vehicles, (b) Equipment cleaning and maintenance (including vehicle and equipment rehabilitation mechanical repairs, painting, fueling, and lubrication), and (c) Deicing/anti-icing operations. Deicing will generally be used to imply both deicing (removing frost, snow or ice) and anti -icing (preventing accumulation of frost, snow or ice) activities. 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 permit, authorization, or approval. 3. 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. 4. This permit covers activities associated with the discharge of stormwater from the storm sewer system and industrial activities identified herein within the jurisdictional area of the permittee as described in the approved SWMP. The permit applies to current and future jurisdictional areas of the permittee, as well as areas that seek coverage under this permit through inter -local or other similar agreements with the permittec. Agreements for coverage under this permit must be approved by the Division of Water Quality, herein referred to as the Division. If a tenant obtains authorization under this permit and develops a Plan for discharges from the commercial tenant's own areas of the airport, that Plan must be coordinated and integrated with the Plan for the entire airport. North Carolina Global TransPark Authority shall maintain a list of all current tenants by type and SIC Code. The Director may require a tenant to apply for and obtain an individual Part 1 Page 1 of 3 Permit No. NCS000516 permit or an alternative General Permit for industrial activities outside the scope of this permit per Part I - Permit Coverage, paragraph 1 above. 5. The Division may deny or revoke coverage under this permit for separate entities and require independent permit coverage as deemed necessary. In addition, the permittee may petition the Division to revoke or deny coverage under this permit for specific entities. 6. Under the authority of Section 402(p) of the Clean Water Act and implementing regulations 40 CFR Part 122, 123 and 124, North Carolina General Statutes 143-215.1 and Session Law 2006- 246 and in accordance with the approved SWMP, all provisions contained and referenced in the SWMP are enforceable parts of this permit. The permittee will develop and implement its approved SWMP in accordance with Section 402(p)(3)(B) of the Clean Water Act, provisions outlined by the Director, and the provisions of this permit. . This permit includes provisions to ensure that discharges do not cause or contribute to exceedances of water quality standards. This permit sets technology -based limitations in the form of Best Management Practices that apply to all pollutants associated with industrial activity. The permit requires the development and proper implementation of the SWMP. The purpose of the SWMP is to reduce the discharge of pollutants from the stormwater sewer system 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 SWMP constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. Successive iterations of the SWMP 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 SWMP. 8. If at any time the Division determine(s) that the permittee's discharge causes or contributes to an exceedance of applicable water quality standards, the permittee must take corrective actions and conduct follow-up monitoring. If the Division makes the determination that the permittee's discharge causes or contributes to an exceedance of a water quality standard, the permittee must comply with any requirements or schedules, including submitting additional information concerning the potential cause of the exceedance. 9. The permit authorizes the point source discharge of stormwater runoff from the storm sewer system and industrial activities identified herein. In addition, discharges of non-stormwater are also authorized through the storm sewer system of the permittee if such discharges are: (a) Permitted by, and in compliance with, another permit, authorization, or approval, 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 and fire hydrant flushing; • landscape irrigation; • diverted stream flows; • rising groundwaters; • uncontaminated groundwater infiltration; Part I Page 2 of 3 Permit No. NCS000516 • uncontaminated pumped groundwater; • discharges from uncontaminated potable water sources; • foundation or footing drains; • air conditioning condensate (commercial/residential); • irrigation waters; • ground water or spring water; • 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; • routine external building wash down that does not use detergents; • incidental windblown mist from cooling towers that collects on rooftops or adjacent portions of the facility, but NOT intentional discharges from the cooling tower (e.g., piped cooling tower blowdown or drains); and • flows from emergency fire fighting. The Division may require that non-stormwater flows of this type be controlled by the permittee's Stormwater Plan. 10. Unless otherwise stated, full compliance with the requirements of the permit is expected upon the effective date of the permit. Part I Page 3 of 3 PART II FINAL LIMITATIONS AND CONTROLS FOR PERMITTED DISCHARGES SECTION A: PROGRAM IMPLEMENTATION The permittee will manage and oversee all provisions of its SWMP to reduce pollutants discharged from the separate stormwater sewer system. This includes, but is not limited to, the following areas: The permittee will maintain adequate legal mechanisms, such as regulations, ordinances, policies and/or procedures to implement all provisions of the SWMP. 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 SWMP. 2. The permittee's SWMP will be managed such that the discharge of pollutants from the stormwater sewer system is reduced to the maximum extent practicable. It is anticipated that in order to meet this provision, implementation of the SWMP 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 permittee will maintain the components of the SWMP to prohibit, to the maximum extent practicable, illicit connections, spills and illegal dumping into the stormwater sewer system. 4. The permittee will maintain adequate funding and staffing to manage the provisions of the SWMP. The permittee will implement appropriate education, training, outreach, and public involvement programs to support the objectives of this stormwater discharge permit and the SWMP. The permittee will maintain a program to reduce pollution from construction site runoff as described in the SWMP and in accordance with this permit. The permittee will maintain 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 BMPs. The permittee will develop and maintain an appropriate program to reduce the potential for stormwater pollution. 9. Proposed permit modifications must be submitted to the Director for approval. 10. Discharges of a hazardous substance or oil in excess of reporting quantities caused by a non- stormwater discharge (e.g., a spill of oil into a separate storm sewer) are not authorized by this permit. In the event of a spill, the requirements of Section 311 of the CWA and other applicable provisions of Sections 301 and 402 of the CWA continue to apply. Part It Page 1 of 14 Permit No. NCS000516- 1 l . If the permittee becomes subject to an approved TMDL, and following notice of such by the Division, the permittee shall implement a TMDL Water Quality Recovery Program. The following additional requirements apply. (a) Within two years after receiving the Division's notice that the permittee is subject to a TMDL, the permittee shall establish a TMDL Water Quality Recovery Program and shall identify the locations of all currently known storm sewer system outfalls within its jurisdictional area with the potential of discharging the pollutant(s) of concern: to the impaired segments, to their tributaries, and to segments and tributaries within the watershed contributing to the impaired segments. The permittee shall also develop a schedule to discover and locate all other storm sewer system 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 pennittee shall develop a monitoring plan for each pollutant of concern. The monitoring plan shall include the sample location by verbal description and latitude and longitude coordinates, sample type, frequency, any seasonal considerations, and a monitoring implementation schedule for each pollutant of concern. Where appropriate, the permittee may reduce the monitoring burden by proposing to monitor outfalls that the Division would'consider substantially similar to other outfalls. The permittee may also propose in -stream monitoring where it would complement the overall monitoring plan. The monitoring plan shall be adjusted as additional outfalls are identified in accordance with the schedule required in (a) above and as accumulating data may suggest. (c) The permittee shall include the location of all currently known stormwater sewer system outfalls with the potential of discharging the pollutant(s) of concern, the schedule for discovering and locating currently unknown stormwater sewer system 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 SWMP 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 SWMP 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. Implementation of the appropriate best management practices constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. (e) Following any review and comment by the Division on the TMDL Water Quality Recovery Program, the permittee shall incorporate any necessary changes into the program. The permittee shall incorporate the revised TMDL Water Quality Recovery Program into the SWMP. The permittee can identify the impaired stream segments in the stormwater sewer system jurisdictional area by referencing the 2004 Integrated 305(b) and 303(d) Report (or current version), available on the website of the Division of Water Quality Modeling and TMDL Unit. Part II Page 2 of 14 Permit No. NCS000516 12 If a wasteload allocation (WLA) has been established that applies to the permittee's discharge, the permittee must develop and implement all necessary controls to meet that allocation. The permittee must verify that their discharge complies with the WLA through the appropriate discharge monitoring. Failure to comply with a relevant WLA is a violation of this permit. If the permittee has properly complied with the requirements of this permit, and finds that the applicable TMDL does not specify a wasteload allocation or other requirements either individually or categorically for the permittee's discharge (including disallowing such discharge), compliance with this permit will be deemed adequate to meet the requirements of the TMDL. If a TMDL has not been established that applies to the permittee's discharge the permittee must comply with the requirements of this permit and any additional conditions stipulated by the Division. If the permittee has properly complied with all such requirements then compliance with this permit will be deemed adequate to meet the requirements for discharging to an impaired water. 13. This permit stipulates pollutant benchmark concentrations. The benchmark concentrations do not constitute direct numeric effluent limitations; a benchmark exceedance, therefore, is not a permit violation. Benchmark monitoring data are primarily to determine the overall effectiveness of the SWMP and to assist in knowing when additional corrective action may be necessary to protect water quality. If the average of four quarterly discharge samples exceed a benchmark concentration the permittee must review their SWMP and BMPs to determine whether any improvement or additional controls are needed to reduce that pollutant in the stormwater discharge(s). Failure to undertake and document the review, take the necessary corrective actions, or follow notification procedures stipulated in this permit are violations of this permit. SECTION B: STORMWATER MANAGEMENT PROGRAM The permittee must maintain and enforce a storm water management program designed to reduce the discharge of pollutants from the MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act. The storm water management program should include management practices; control techniques and system, design, and engineering methods; and such other provisions as the permitting authority determines appropriate for the control of such pollutants. The storm water management program must include the following information for each of the six minimum control measures described in Section B.2 of this permit: (a) The best management practices (BMPs) that the permittee or another entity will implement for each of the storm water minimum control measures; (b) The measurable goals for each of the BMPs including, as appropriate, the months and years in which the permittee will undertake required actions, including interim milestones and the frequency of the action; and (c) The person or persons responsible for implementing or coordinating the BMPs for the stormwater management program. Part Il Page 3 of 14 Permit No. NCS000516- 2. Minimum Control Measures: The six minimum control measures that must be included in the stormwater management program are: (a) Public Education and Outreach on Storm Water Impacts: The permittee must maintain a public education program, to distribute educational materials to the community, conduct equivalent outreach activities about the impacts of storm water discharges on water bodies, raise public awareness on the causes and impacts of stormwater pollution and inform the public on the steps they can take to reduce pollutants in storm water runoff. (b) Public Involvement/Participation: The permittee must at a minimum, provide opportunities for the public to participate in program development and implementation and comply with State, Tribal, and local public notice requirements when implementing a public involvement/participation program. (c) Illicit Discharge Detection and Elimination: (i) Develop, maintain and enforce a program to detect and eliminate illicit discharges (as defined in 40 CFR §122.26(b)(2)) into the MS4; (ii) Develop and maintain a storm sewer system map, showing the location of all outfalls and the names and location of all waters of the United States that receive discharges from those outfalls; (iii) To the extent allowable under State, Tribal or local law, effectively prohibit, through ordinance, or other regulatory mechanism, non -storm water discharges into the storm sewer system and implement appropriate enforcement procedures and actions; (iv) Develop and maintain a plan to detect and address non -storm water discharges, including illegal dumping, to the system; (v) inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste; and (vi) Address the following categories of non -storm water discharges or flows (i.e., illicit discharges) only if identified as significant contributors of pollutants to the MS4: water line flushing, landscape irrigation, diverted stream flows, rising ground waters, uncontaminated ground water infiltration (as defined at 40 CFR §35.2005(20)), uncontaminated pumped ground water, 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 effective prohibition against non -storm water and need only be addressed where they are identified as significant sources of pollutants to waters of the United States). (vii) The permittee may also develop a list of other similar occasional incidental non - storm water discharges (e.g. non-commercial or charity car washes, etc.) that will not be addressed as illicit discharges. These non -storm water discharges must not be reasonably expected (based on information available to the permittees) to be Part II Page 4 of 14 Permit No. NCS000516 significant sources of pollutants to the Municipal Separate Storm Sewer System, because of either the nature of the discharges or conditions established for allowing these discharges to the MS4 (e.g., a charity car wash with appropriate controls on frequency, proximity to sensitive waterbodies, BMPs on the wash water, etc.). The permittee must document in the SWMP any local controls or conditions placed on the discharges. The permittee must include a provision prohibiting any individual non -storm water discharge that is determined to be contributing significant amounts of pollutants to the MS4: (d) Construction Site Storm Water Runoff Control (i). The permittee relies on the NCDEQ Division of Land Resources (DLR) Erosion and Sediment Control Program to comply with this minimum measure. (ii). The NCDEQ Division of Land Resources Erosion and Sediment Control Program effective meets the requirements of the Construction Site Runoff Controls by permitting and controlling development activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development. This program is authorized under the Sediment pollution Control Act of 1973 and Chapter 4 of Title 15A of the North Carolina Administrative Code. This program includes procedures for public input, sanctions to ensure compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices, review of site plans which incorporates consideration of potential water quality impacts, and procedures for site inspection and enforcement of control measures. (iii). NCDEQ Division of Energy, Mineral and Land Resources NPDES general permit for construction activitics (NCGO10000) effectively meets the above requirements. The NCGO10000 permit establishes requirements for construction site operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality. (iv). The permittee must provide and promote a means for the public to notify the appropriate authorities of observed erosion and sedimentation problems. The permittee may implement a plan promoting the existence of the NCDEQ, Division of Land Resources "Stop Mud" hotline to meet the requirements of this paragraph. (v). The permittee may pursue local government implementation of the Erosion and Sediment Control Program by requesting a "minor modification" to the permit. Part 11 Page 5 of 14 Permit No. NCS000516 (e) Post -Construction Storm Water Management in New Development and Redevelopment (i) Implement and enforce a program to address storm water runoff from new development and redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that discharge into the MS4. The program must ensure that controls are in place that would prevent or minimize water quality impacts; (ii) Develop and implement strategies which include a combination of structural and/or non-structural best management practices (BMPs) appropriate for the community; and (iii) Use an ordinance or other regulatory mechanism to address post -construction runoff from new development and redevelopment projects to the extent allowable under State, Tribal or local law; and (iv) Ensure adequate long-term operation and maintenance of BMPs. (f) Pollution Prevention and Good Housekeeping for NCGTP Operations (i) Identify each area where industrial materials or activities are exposed to stormwater. Industrial materials or activities include, but are not limited to: material handling equipment or activities; industrial machinery; raw materials; industrial production and processes; intermediate products, by-products, final products and waste products. (ii) Material handling activities include, but are not limited to: the storage, loading and unloading, transportation, disposal, or conveyance of raw material, intermediate products, final products and waste products. (iii) Maintain and implement an operation and maintenance program for each industrial activity where industrial materials or activities are exposed to stormwater and for each structural stormwater BMPs. For each area where industrial materials or activities are exposed to stormwater, include a narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or particulate generating or control processes, and waste disposal practices. List all stormwater control systems, 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 specify the frequency of inspections, operation and maintenance, and housekeeping activities, as well as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or stormwater pollution. Inspection of material handling areas and regular cleaning schedules of these areas shall be incorporated into the program. The inspection and any subsequent maintenance activities performed shall be documented, recording date and time of inspection, individual(s) making the inspection, and a description of the facility's stormwater control and systems. NCGTP must identify and map all structural stormwater BMPs. The map must identify the stormwater outfalls corresponding to each of the BMP as well as the receiving waters to which these BMPs discharge. The map must be maintained and updated regularly and be available for review by the Part II Page 6 of 14 Permit No. NCS000516 permitting authority. NCGTP shall maintain and implement, assess annually and update as necessary an O&M program for all structural stormwater BMPs. The O&M program shall specify the frequency of inspections and routine maintenance requirements. NCGTP shall inspect and maintain all structural stormwater BMPs in accordance with the schedule developed by NCGTP. NCGTP must document inspections and maintenance of all structural stormwater BMPs. (iv) Describe and assess the potential for the following activities and facility areas to contribute pollutants to stormwater discharges: aircraft, runway, ground vehicle and equipment maintenance and cleaning; aircraft and runway deicing operations (including apron and centralized aircraft deicing stations, runways, taxiways and ramps). If deicing chemicals are used, the permittee must maintain a record of the types (including the Material Safety Data Sheets [MSDS}) used and the monthly quantities, either as measured or estimated. This includes all deicing chemicals, not just glycols and urea (e.g., potassium acetate), because large quantities of these other chemicals can still have an adverse impact on receiving waters. Commercial tenants or other fixed -based operations that conduct deicing operations must provide the above information to the airport authority for inclusion in the airport authority's Plan. The pollutant list must include all significant materials, including any hazardous substances or oil handled, treated, stored, or disposed of that may be exposed to stormwater. (v) Secondary Containment Requirements. Secondary containment is required for: bulk storage of liquid materials; 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 directly 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), and any stormwater that accumulates in the containment area shall be at 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 the material stored within the containment area. (vi) Conduct and document regular inspections at industrial activities where industrial materials or activities are exposed to stormwater, structural stormwater BMPs, and stormwater conveyance systems. Evaluate the sources, document deficiencies, plan corrective actions, implement appropriate controls, and document the accomplishment of corrective actions. (vii) Describe measures that prevent or minimize contamination of the stormwater runoff from industrial activities with the potential for generating polluted stormwater runoff. (viii) Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel (or the team) responsible for Part 11 Page 7 of 14 Permit No. NCS000516 implementing the SPRP shall be identified in a written list incorporated into the SPRP. 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. 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. Response procedures must include notification of appropriate facility personnel, emergency agencies, and regulatory agencies, and procedures for stopping, containing and cleaning up spills. Employees who may cause, detect or respond to a spill or leak must be trained in these procedures and have necessary spill response equipment available. Include contact information for individuals and agencies that must be notified in the event of a spill in the Plan and in other locations where it will be readily available. (ix) Develop training program materials. Maintain and implement annual training of GTP staff specific training for pollution prevention and good housekeeping procedures. The permittee must document all training sessions and the employees who received the training. All employees who work in areas where industrial materials or activities are exposed to stormwater, or are responsible for implementing good housekeeping activities (e.g., inspectors, maintenance personnel), must participate in the annual training. Training must include such topics as spill response, good housekeeping, material management practices, inspection and operation and maintenance. The program must include employee training to prevent and reduce storm water pollution from activities such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm water system maintenance. (x) Deicing and Anti -Icing Industrial Control Plan: NCGTP maintain and implement a management plan to minimize possible glycol and urea discharges from airport areas with these operations. Plan requirements shall address: (A) Include Best Management Practices (BMPs), economically reasonable and appropriate in light of current industry practices, that are selected, designed, installed, implemented and maintained in accordance with good engineering practices to eliminate or reduce pollutants in the permittee's discharge; (B) Describe and ensure implementation of practices used to eliminate or reduce pollutants in stormwater discharges; (C) Evaluate present operating procedures to consider alternative practices that would reduce the overall amount of deicing/ anti -icing chemical used and/or lessen the environmental impact of the pollutant source. (D) Evaluate whether excessive application of deicing chemicals occurs and adjust as necessary, consistent with considerations of flight safety. Part 11 Page 8 of t4 Permit No. NCS000516 (E) Maintain and implement the plan for the minimization of the release of materials used for de-icing into the stormwater system. This plan shall address: • The current use and practices employed at the airport for the control and minimization of entry of the de-icing materials into the stormwater system; and • The means that may be practicable for modifying current use and practices to collect the runoff that occurs during and following the application of the de-icing materials. • Feasible alternatives to the use of urea and glycol -based deicing chemicals to reduce the aggregate amount of deicing chemicals used and/or lessen the environmental impact, consistent with considerations of flight safety. • Airport authorities must determine annually the usage rate of deicing/anti-icing chemicals at their facility. The total amount of deicing/anti-icing chemicals used at an airport facility is the cumulative amount used by the airport authority and each tenant of the airport facility. In determining the fluid amounts of deicing/anti- icing chemicals used at a facility, operators should use the pre - dilution volume. (vi) Prepare estimates of annual pollutant loadings discharged to storm sewer systems or surface waters resulting from discharges of spent deicing/anti-icing chemicals from the facility. The loading estimates shall reflect the amounts of deicinglanti- icing chemicals discharged to separate storm sewer systems or surface waters. SECTION C: MONITORING REQUIREMENTS 1. Benchmark Monitoring where Deicing/Anti-icing Activities Occur (a) The permittee must monitor those outfalls from the airport facility that collect runoff from areas where deicing/anti-icing activities occur (SIC 45124581) for all benchmark parameters listed in Table 1. Monitoring for all benchmark parameters must be conducted according to the procedures in Part 11 Section C, Paragraph 3. Table l - Benchmark Monitoring Parameters and Concentrations Paratnetei• . _ Benchynark Monitorin Concentration -; Biochemical Oxygen Demand BODS 30 m L Chemical Oxygen Demand COD 120 m L Ammonia 19 m PH 6.0 - 9.0 s.u. Total Suspended Solids (TSS) 100 m L Oil and Grease 30 m I Part II Page 9 of 14 Permit No. NCS000516- (b) Benchmark monitoring must be conducted once during the December through February time period provided a deicing event occurs, except as provided in Part Il Section C, Paragraph 3. (c) Submit results from all benchmark monitoring to the Division. (d) If the monitoring values exceed the benchmark the permittee must review their SWMP within 14 days to determine if it satisfies the requirements of this permit. The permittee must document the date and findings of their review. If the permittee determines that the SWMP satisfies the requirements of this permit, the permittee must document the justification for this determination. If the permittee determines that the SWMP does not satisfy the requirements of Part II the permittee must initiate corrective action. (f1 The permittee may exercise a waiver of the benchmark monitoring requirements at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. If the permittee exercises this waiver, the permittee must maintain a certification with the SWMP stating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to stormwater. The permittee must sign and certify the waiver. (g) Where two or more outfalls discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and stormwater management practices occurring within the drainage areas of the outfalls, the permittee may conduct visual monitoring of the discharge at just one of the outfalls and report that the results also apply to the substantially identical outfall(s), provided the permittee documents in the SWMP the following: locations of the outfalls, why the outfalls are expected to discharge substantially identical effluents, estimates of the size of the drainage area (in square feet) for each of the outfalls, and an estimate of the runoff coefficient of the drainage areas (low: under 40 percent; medium: 40 to 65 percent; high: above 65 percent). Discharges to Impaired Waters. Monitoring is required for discharges to impaired waters unless the permittee documents that there is no exposure of the pollutant of concern to stormwater at the permittee's site. (a) The permittec must submit results from all monitoring to the Division. Discharge Monitoring Reports shall be delivered to the Division no later than 30 days from the date the facility receives the sampling results from the laboratory. (b) For discharges that are conveyed directly or indirectly to impaired waters, monitoring for the pollutant of concern must be conducted at a minimum of once each permit year throughout the term of the permit. This monitoring requirement is waived after one year if the pollutant of concern is not detected in the permittee's stormwater discharge. (c) For discharges that are conveyed directly or indirectly to waters for which EPA has approved or established a TMDL with a wasteload allocation applicable to the permittee's discharge (either specifically or categorically), monitoring for the wasteload allocation pollutant of concern must be conducted, consistent with any instructions in TMDL documentation. If the TMDL documentation does not specify monitoring requirements, monitoring for the pollutant of concern must be conducted at a minimum of once each permit year throughout the term of the permit, unless this permit already Part II Page 10 of 14 Permit No. NCS000516 assigns the permittee's discharge a benchmark for the pollutant of concern, in which case the permittee must follow the benchmark monitoring schedule. The monitoring year begins on the day the permittee's discharge is authorized. This monitoring must be conducted in addition to all other monitoring requirements prescribed in this permit. Monitoring of a pollutant of concern for which the discharge has been assigned a wasteload allocation cannot be waived unless the WLA is specified only in terms of BMPs, in which case the monitoring requirement is waived after one year if the pollutant of concern is not detected in the stormwater discharge and the permittee documents that the permittee has adopted the required BMPs. Monitoring Instructions (a) The permittee must sample in accordance with the following provisions: i. Take a minimum of one grab sample from a discharge resulting from a storm event with at least 0.1 inch of precipitation (defined as a measurable, event), provided the interval since the preceding measurable storm is at least 72 hours. The 72-hour storm interval is waived when the preceding measurable storm did not yield a measurable discharge, or if you are able to document that less than a 72-hour interval is representative for local storm events during the sampling period. ii. Take the grab sample during the first 30 minutes of the discharge. If it is not possible to take the sample during the first 30 minutes, sample during the first hour of discharge and describe why a grab sample during the first 30 minutes was not possible. Submit this information on or with the Discharge Monitoring Report. If the sampled discharge co -mingles with discharges not authorized under this permit prior to reaching the receiving water body, attempt to sample the stormwater discharge before it mixes with other waste streams. iii. Sample collection, preservation and analysis must be conducted according to test procedures approved under 40 CFR Part 136. (b) Along with the results of the monitoring, provide the date and duration (in hours) of the storm event(s) sampled, rainfall measurements or estimates (in inches) of the storm event that generated the sampled runoff, the duration between the storm event samples and the end of the previous measurable (greater than 0.1 inch rainfall) storm event, and an estimate of the total volume (in gallons) of the discharge samples. (c) When adverse weather conditions prevent the collection of samples according to the relevant monitoring schedule, take a substitute sample during the next qualifying storm event. Adverse conditions (i.e., those that are dangerous or create inaccessibility for personnel) may include events such as local flooding, high winds, electrical storms, or situations that otherwise make sampling illogical, such as drought or extended frozen conditions. (d) The Division may provide written notice requiring additional discharge monitoring briefly stating the reasons for the monitoring, locations and parameters to be monitored, frequency and period of monitoring, sample types, and reporting requirements. Part 11 Page 11 of 14 Permit No. NCS000516- 4. Qualitative Monitoring Requirements (a) The permittee must perform and document a quarterly visual examination of all stormwater discharge outfalls associated with industrial activity, except as provided for in Part II.C.3(c), Adverse Weather Conditions. The visual examination shall be made during daylight hours during a rain event. If no rain event resulted in runoff during daylight hours from the facility during a monitoring quarter, for each stormwater discharge outfall associated with industrial activity, the permittee shall document that no runoff occurred. (b) Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of representative outfall status. Qualitative monitoring is for the purpose of evaluating the effectiveness of the SWMP and assessing new sources of stormwater pollution. No analytical tests are required. Visual examinations must be made on samples collected within the first 30 minutes (or as soon thereafter as practical, but not to exceed 1 hour) of when the runoff or snowmelt begins discharging form the outfall. All samples must be collected from a rain event as defined herein. The 72-hour storm interval is waived when the preceding measurable storm did not yield a measurable discharge, or if it can be documented that less than a 72-hour interval is representative for local storm events during the sampling period. The examination must document observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution. (c) In the event an atypical condition is noted at a stormwater discharge outfall, 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 SWMP. (d) Visual examination reports must be maintained onsite with the SWMP. The report must include the examination date and time, inspection personnel, nature of the discharge (i.e., runoff or snow melt), visual quality of the stormwater discharge (including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution), and probable sources of any observed stormwater contamination. (e) All qualitative monitoring will be performed four times per year, once in the periods of January —March; April — June; July — September; and October — December. In the January — March period the qualitative monitoring shall be performed during a representative storm event and within 60 minutes of deicing/anti-icing activities. (f) If the permittee's qualitative monitoring indicates either 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 appropriate. (g) The permittee may exercise a waiver of the visual monitoring requirements at a facility that is inactive and unstaffed, as long as there are no industrial materials or activities exposed to stormwater. If the permittee exercises this waiver, the permittee must maintain a certification stating that the site is inactive and unstaffed, and that there are no industrial materials or activities exposed to stormwater, The permittee must sign and certify the waiver. Part II Page 12 of 14 Permit No. NCS000516 SECTION D: COMPLIANCE EVALUATION OF INDUSTRIAL ACTIVITIES The permittee must conduct a comprehensive site compliance evaluation of airport facilities subject to industrial stormwater permitting requirements at least once a year. 2. Inspections must cover all the areas where industrial materials or activities are exposed to stormwater, along with areas where spills and leaks have occurred in the past 3 years. Inspectors must examine the following: (a) Industrial materials, residue or trash that may have or could come into contact with stormwater; (b) Leaks or spills from industrial equipment, drums, tanks and other containers; (c) Offsite tracking of industrial or waste materials, or sediment' where vehicles enter or exit the site; (d) Tracking or blowing of raw, final or waste materials from areas of no exposure to exposed areas; (e) Evidence of, or the potential for, pollutants entering the drainage system; and (f) Evidence of pollutants discharging to surface waters at all facility outfall(s), and the condition of and around the outfall, including flow dissipation measures to prevent scouring. (g) Conduct annual site compliance evaluations during periods of actual deicing operations. If not practicable during active deicing, or the weather is too inclement, conduct annual site compliance evaluations when deicing operations are likely to occur and the materials and equipment for deicing are in place. The permittee must consider the results of the past year's visual and analytical monitoring when planning and conducting inspections. Stormwater BMPs associated with airport facilities subject to industrial stormwater permitting requirements identified in the SWMP must be observed during active operation, i.e., during a stormwater runoff event, to ensure that they are functioning correctly. If discharge locations are inaccessible, nearby downstream locations must be inspected. 4. When compliance evaluation schedules overlap with routine facility inspections, the annual compliance evaluation may also be used as one of the routine inspections, as long as all components of both types of inspections are included. SECTION E: CORRECTIVE ACTIONS, FOLLOW-UP MONITORING AND REPORTING 1. The permittee must take corrective action whenever: (a) Routine facility inspections, comprehensive site compliance evaluations, or any other process, observation or event result in discovery of any deficiency; or (b) Following a benchmark exceedance, based on the average of 4 quarterly monitoring events, the permittee determines as a result of reviewing the permittee's SWMP that the permittee's SWMP does not meet the requirements of Part 11 of this permit. Part 11 Page 13 of 14 Permit No. NCS000516' 2. The permittee must review their SWMP and modify it as necessary to address the deficiency(ies). Revisions to the SWMP must be completed within 14 calendar days following the discovery. When BMPs need to be modified or added, implementation must be completed before the next anticipated storm event if possible, but no later than 60 days after discovering the deficiency(ies), or as otherwise provided or approved by the Division. The amount of time taken to modify a BMP or implement additional BMPs must be documented. Any corrective actions taken as a result of inspections must be documented and retained for the 3- year period following permit expiration or termination. 4. If at any time monitoring results indicate that the permittee's discharge exceeds a specific wasteload allocation, or the permittee becomes aware that a discharge causes or contributes to an exceedance of a water quality standard, the permittee must take immediate steps to eliminate the exceedances. Within 30 calendar days of implementing the relevant corrective action(s) (or during the next qualifying runoff event, should none occur within 30 calendar days) the permittee must undertake additional monitoring to verify that the modified BMPs are effectively protecting water quality. The permittee need only conduct follow-up monitoring for pollutant(s) with prior exceedances unless the permittee has reason to believe that the modifications may have reduced pollutant prevention or removal capacity for other pollutants of concern. If the follow-up monitoring value does not exceed the effluent limitation or other relevant standard, the permittee must submit the follow-up monitoring data to the Division no later than 30 days after the permittee receives the lab results. In this case, no additional follow-up monitoring is required. Should the follow-up monitoring indicate that the wasteload allocation, water quality standard or other relevant standard is still being exceeded, the permittee must submit an Exceedance Report no later than 30 days after the permittee received the lab results. The report must include the permit identification number; facility name, address and location; receiving water; monitoring data from this and the preceding monitoring event(s); an explanation of the situation; what was done and intend to do (should corrective actions not yet be complete) to further reduce pollutants in the discharge; and an appropriate contact name and phone number. The permittee must continue to conduct follow-up monitoring at an appropriate frequency, but no less often than quarterly, until the discharge no longer exceeds the standard, unless the requirement for additional follow-up monitoring is waived by the Division. 6. Failure to undertake the necessary corrective actions within the stipulated time frames constitutes a violation of this permit. The underlying cause of the inadequacy or discharge standard exceedance, e.g., failure to properly implement the SWMP, may also constitute an independent violation of this permit. Failure to complete follow-up monitoring and reporting within the stipulated time frames constitutes a violation of this permit. Part II Page 14 of 14 Permit No. NCS000516 PART III PROGRAM ASSESSMENT Implementation of the SWMP will include documentation of all program components that are being undertaken including, but not limited to, inspections, maintenance activities, educational programs, implementation of BMPs, enforcement actions, and other stormwater activities. If monitoring and sampling are being performed documentation of results shall be included. Documentation will be kept on -file by the permittee for a period of five years and made available to the Director or his authorized representative immediately upon request. 2. The permittee's SWMP will be reviewed and updated as necessary whenever there is a change in design, construction, operation, or maintenance which has a significant impact on the discharge, or potential for discharge, of pollutants to surface waters, routine inspection or compliance evaluation determines deficiencies in BMPs, an inspection by a local, State, or Federal official determines that modifications to the Plan are necessary, or there is a spill, leak or other release; or any time there is an unauthorized discharge. 3_ All aspects of permittee's SWMP shall be reviewed and updated on an annual basis. The annual update shall include an updated list of significant spills or leaks of pollutants for the previous three years, or the notation that no spills have occurred. The annual update shall include re- certification that the stormwater outfalls have been.evaluated for the presence of non-stormwater discharges. Plan modifications must be made within 30 calendar days after discovery, observation or event requiring a modification. Implementation of new or modified BMPs must be initiated before the next storm event if possible, but no later than 60 days after discovery, or as otherwise provided or approved by the Division. The amount of time taken to modify a BMP or implement additional BMPs must be documented. If the Plan modification is the result of a release or unauthorized discharge, the permittee must document a description of the release, the date of the release; the circumstances leading to the release and actions taken in response to the release; and measures to prevent the recurrence of such releases. 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. 4. The Director may notify the permittee when the SWMP does not meet one or more of the requirements of the permit. Within 30 days of such notice, the permittee will submit a plan and time schedule to the Director for modifying the SWMP to meet the requirements. The Director may approve the corrective action plan, approve a plan with modifications, or reject the proposed plan. The permittee will provide certification in writing (in accordance with Part N) to the Director that the changes have been made. Nothing in this paragraph shall be construed to limit the Director's ability to conduct enforcement actions for violations of this permit. The Division may request additional reporting information as necessary to assess the progress and results of the permittee's SWMP . The permittee must retain a copy of the current Plan SWMP at the facility, and it must be immediately available at the time of an on -site inspection. Part Ili Page 1 of 1 Permit No. NCS000516 PART tV REPORTING AND RECORD KEEPING REQUIREMENTS Annual Report.
