The storm water drainage system consists of approximately 50 miles of drainage pipe that collects and empties storm water into nearby surface water bodies through outfalls. Of the 50 miles of drainage pipe, 20 miles of pipe are associated with Military Family Housing. The main watercourses throughout the installation consist of the Neuse River, Stoney Creek, Hospital Creek, Burge Ditch, Mayfield's Ditch (a tributary to Stoney Creek and Burge Ditch), Prison Ditch (a tributary to Stoney Creek), Golf Course Ditch and Golf Course Lake (a tributary to Burge Ditch), and Bulk Fuels Ditch (a tributary to Prison Ditch). 1.6 Existing Pertinent Permits Storm water at Seymour Johnson AFB is permitted under the NCDEQ, Division of Energy, Mineral, and Land Resources General Permit Numbers NCS000335, NCG150000, and NCG080000, presented in Appendix A. 1-6 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE 2.0 PROPOSED MONITORING LOCATIONS Two outfalls (Outfalls 1 and 15d) have been associated with three vehicle maintenance activities at buildings 3100, 3220, and 3105 using oil or hydraulic oil > 55 gallons per month when averaged over the calendar year and require initial baseline monitoring of storm water runoff. The monitoring locations are shown in Figure 2-1. The observed historical discharge from the outfalls will be evaluated during a measurable storm event. NCGO80000 Part K defines measurable as "a storm event resulting in an actual discharge from the permitted site outfall". NCG150000 Part VI defines measurable storm event as "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 may not apply if the permittee documents that a shorter interval is representative for local storm events during the sampling period, and obtains approval from the local Division of Energy, Mineral, and Land Resources (DEMLR) Regional Office. Two copies of this information and a written request letter shall be sent to the local DEMLR Regional Office. After authorization by the DEMLR Regional Office, a written approval letter must be kept on site in the permittee's [Storm Water Pollution Prevention Plan]. " Following plan concurrence by NCDEQ, these locations will be sampled during subsequent full quarters as established in NCGO8000 and presented in Section 4.3.1. The outfalls will be monitored and any discharge will be reported. If the historical discharge location cannot be accessed for sampling immediately after a measurable storm event, discharge observations and samples will be taken as soon as possible following the measurable storm event. Access improvements for the historical discharge monitoring location will be evaluated, proposed, and upon approval, implemented. The selection of other monitoring sites was based on the following criteria: 1. Facilities that use greater than 55 gallons of new motor and/or hydraulic oil per month when averaged over one year, 2. Discharge flow paths, 3. Location nearest the point of discharge from the facilities outlined above, and 4. Accessibility. Seymour Johnson AFB will adjust sample locations to obtain the most representative and accessible samples as actual discharges are observed and changes occur at monitoring sites. 2.1 Basins and Outfall Descriptions The following storm water outfalls drain the Seymour Johnson AFB installation. The drainage basins associated with these outfalls are described in Section 2.1.1, and outfall descriptions and photographs are included in Section 2.1.2. Delineated drainage basin areas are identified by September 2022 FINAL 2-1 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE number in Figure 2-1.

Drainage Basins 13a and 13b are located on the east side of the installation. These basins include former golf course areas that are primarily pervious surfaces. Runoff from these drainage areas is conveyed through Outfalls 13a and 13b to an area along Oak Forest Road. Drainage Basins 13c through 13i are located on the northeast side of the installation and drain a large portion of installation housing. The outfalls for these basins discharge to Hospital Creek. 2-6 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE Drainage Basin 13j drains residential and commercial areas from the center of the installation and the northwest portion of installation housing. Storm sewers serving this drainage basin discharge to Hospital Creek in multiple locations via underground piping throughout the installation. As a result, a distinct outfall representing the entire basin could not be located. However, Outfall 13k drains a portion of Drainage Basin 13j. Outfall 13k was identified adjacent to the "Boston Harbor" concrete headwall at the intersection of Vermont Garrison Street and Dargue Drive. The outfall discharges to Hospital Creek. Drainage Basins 15a, 15b, 15c, and 15e are located on the north side of the installation and include administrative facilities, the installation clinic, a campground, and single-family housing. Runoff from these drainage areas is conveyed to Hospital Creek before discharging to Stoney Creek. Outfalls for basins 15b and 15c could not be located. Drainage Basin 15d is located in the northwest portion of the installation. Runoff is conveyed through Outfall 15d to Hospital Creek. Hospital Creek enters the installation under Oak Forest Road and flows along the edge of the former golf course, near the 15th hole. It is piped under Vermont Garrison Street, running parallel for approximately 1,000 feet. It is piped underground and reappears on the northern side of Wright Brothers Avenue near the clinic.

The survey was conducted to obtain baseline information 18 on the presence and nature of potential discharges of storm water, and to choose appropriate 2-32 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE 1 discharge monitoring points. The site reconnaissance was conducted during working hours to 2 assess site activities at Seymour Johnson AFB. 3 DAWSON and Seymour Johnson AFB personnel inspected vehicle maintenance facilities on 4 August 24, 2022. Preliminary assessment of potential discharge monitoring points included the 5 following activities: 6 1. Analysis of purchase orders and waste oil reports for vehicle maintenance facilities, 7 and 8 2. Visual inspections of drainage outfalls. 9 2.5 Proposed Discharge Monitoring Points for Analytical Monitoring 10 Two locations were selected for monitoring based on the site reconnaissance, review of storm 11 water control features, and analysis of the installation facilities that use greater than 55 gallons of 12 motor and/or hydraulic oil per month when averaged over a year. The following criteria were 13 considered for the selection of proposed discharge monitoring points: 14 1. Facilities that use greater than 55 gallons of new motor and/or hydraulic oil per month 15 when averaged over one year, 16 2. Discharge flow paths, 17 3. Location nearest the point of discharge from the facilities outlined above, and 18 4. Accessibility. 19 Table 2-3 Proposed Analytical Monitoring Points Outfall Number Location Sample Location East of Collier Avenue and Luke 01 15-inch diameter concrete pipe Street intersection Northwest side of Jabara Avenue and 15d 40-inch diameter concrete pipe Hospital Creek intersection 20 Monitoring and sampling will occur following exit from the outfall piping or stream as close to 21 the discharge point as possible.

Seymour Johnson AFB personnel are pending access to the eDMR and will continue to 33 submit results in accordance with the process outlined in part G-2 of NCGO80000 included in 34 Appendix A until access to eDMR is received. 3-2 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE 4.0 MONITORING CONSTITUENTS, MONITORING PROCEDURES, AND ANALYTICAL TEST PROCEDURES 4.1 Monitoring Constituents NCDEQ requires monitoring for three parameters: Total Suspended Solids (TSS) (EPA method 160.2), Non -Polar Oil and Grease (EPA Method 1664 [SGT-HEM]), and pH. Test procedures for the analysis of pollutants must conform to the North Carolina Environmental Management Commission regulations published under North Carolina General Statutes 143-215.63 et seq., the Water and Air Quality Reporting Acts, and to regulations issued under Section 304(g), 33 United States Code 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136. 4.2 Monitoring Equipment Manual grab samples will be taken at a given discharge monitoring point for each sampling event. The contractor completing sampling will furnish rain gauge and pH equipment. For confirmation weather station data, two rain gauges are located at the Seymour Johnson AFB airfield on each side of the runway. The rain gauges are telemetric. Data from the two airfield gauges are available to USAF personnel via the 4th Operations Support Squadron Weather Flight at (919) 722-4089. The telemetric data is updated in 10-minute intervals. The contractor furnished rain gauge and telemetric rain gauge data will be monitored during storm events by the base sampling contractor and confirmed with the Seymour Johnson AFB Water Quality Program Manager to determine if a measurable event has occurred. Rainfall accumulation will be recorded for the rain gauges during the measurable event. 4.3 Monitoring Procedures To meet the intent of the monitoring required by NCGO80000 all test procedures must produce minimum detection and reporting levels, and all data generated must be reported down to the procedure's minimum detection or lower reporting level. If no approved methods are determined to achieve minimum detection and reporting levels below permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method will be used. All lab sample results will be provided to the installation in the units stated in the permit (mg/L, gallons/month, inches) for easy comparison. Grab samples will be sent to a North Carolina- certified laboratory. 4.3.1 Quantitative Sampling Seymour Johnson AFB will implement quantitative monitoring per this BWMP as outlined in the NPDES Permit NCGO80000 for industrial activity classified as vehicle maintenance facilities that use more than 55 gallons of new motor oil and/or hydraulic oil per month when averaged over the September 2022 FINAL 4-1 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE calendar year. Results of the monitoring program will be submitted to NCDEQ according to the provisions of Part E of the NCGO80000 permit. The permit requires that all samples must be taken before the discharge joins or is diluted by any other waste stream, a body of water, or substance. Monitoring points must not be changed without written notification to and approval by NCDEQ (40 CFR 122.41 U]). Total rainfall amount for each sampling event will be recorded in inches and will be determined from the contractor furnished rain gauge located on Seymour Johnson AFB. Samples will be collected quarterly unless the facility is in Tier Two or Tier Three status; a minimum of 30 days will separate any two sampling events during the following periods: 1. January 1 — March 31 2. April 1 — June 30 3. July 1 — September 30 4. October 1 — December 31 Outfall monitoring will begin with the first measurable storm event in the monitoring period meeting all of the following conditions: 1. Occurs at least 72 hours after the previous measurable storm event, 2. Occurs during the facility's normal operating hours, 3. Does not coincide with adverse weather conditions, and 4. Is characteristic of the volume and nature of the permitted discharge. The 72-hour storm interval may not apply if 1. The installation is able to document that a shorter interval is representative for local storm events during the sampling period, 2. The installation obtains approval from the NCDEQ Regional Office, and 3. After authorization by the NCDEQ Regional Office, a written approval letter must be kept on site in the SWPPP. Outfalls not sampled during the first measurable storm event in the monitoring period will be sampled during the next measurable storm event in the monitoring period until a sample has been collected. If, during the entire monitoring period, there is no discharge from an outfall during any measurable storm event, Seymour Johnson AFB will: 1. Report "No Discharge" in the DMR, 2. Note "No Discharge" in the SWPPP, and 3. Submit the DMR within 30 days after the end of the monitoring period. According to NCDEQ, a lack of discharge from an outfall for the monitoring period will not constitute a failure to monitor so long as the above conditions are met. If the sampled storm event 4-2 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE coincides with a known non -storm water discharge deemed permitted under 15A North Carolina Administrative Code 02 .0106, this will be noted on the DMR, presented in Appendix C. Grab samples will be collected, analyzed, and reported for the parameters listed in Table 4-1. Grab samples will be collected from all discharging outfalls within the first 30 minutes of discharge. Typically, automatic grab samplers that acquire true first -flush samples from each qualifying rainfall event, regardless of the time of day or nature of the storm event, are used to collect the storm water runoff from the outfalls. Measurements of pH will then be recorded simultaneous with grab sample collection but no later than 15 minutes after collection. The pH of the runoff will be measured using an electronic pH meter in conjunction with the transfer of the storm water sample from the automatic sampler to the sample bottles provided by the laboratory. The automatic samplers protect the integrity of the sample by completely closing the inlet after the sample is acquired, leaving no head space or other means by which the water sample could be exposed to the air. If an automatic sampler is not completely full (i.e., there is head space because the inlet has not been closed off), depending on the nature of the occurrence, the sampling event may not be considered valid, such that measurements may not be taken. As soon as a qualifying event is known to have occurred, field personnel go to each location, acquire the storm water captured by the automatic samplers, and transfer the sample to the appropriate bottles for transport to the laboratory. Depending on the time of day of the event, the captured storm water will be transferred to the bottles (and the field pH measurement performed) within minutes to hours of the beginning of the storm event. Depending on the intensity of the qualifying storm event, the travel time (referred to as the Time of Concentration) for sufficient storm water from the industrial unit to reach the sampler location may vary from a few minutes to an hour or more after the beginning of the rainfall event. Thus, except for very high intensity storm events, there is typically not a sufficient volume of storm water to acquire a sample until late into the storm event.

According to NCG080000, exceeding a benchmark value is not a permit violation; however, failure to respond according to the methods indicated below is a violation. An exceedance of any benchmark value will require a tiered response for that outfall as described in NCG080000, Section E-5 through E-7. A single exceedance of a benchmark value requires a Tier One response for that outfall. Two benchmark value exceedances for the same parameter in a row requires a Tier Two response for that outfall. Four benchmark exceedances for a single parameter within the permit term require a Tier Three response for that outfall. 4.3.2 Qualitative Sampling Qualitative monitoring (color, odor, clarity, floating solids, suspended solids, foam, oil sheen, erosion or deposition at the outfall, and other visual indicators of storm water pollution) requires a visual inspection of each storm water outfall associated with industrial activities. Figure 4-1 shows the location of industrial storm water outfalls. No analytical tests are required. The purpose of qualitative monitoring is to implement a quick and inexpensive way to evaluate the effectiveness of Seymour Johnson AFB's SWPPP, identify the potential for new sources of storm water 4-4 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE pollution, and prompt Seymour Johnson AFB's response to pollution. Qualitative monitoring will follow the installation's NCDEQ-approved BWMP procedures. Qualitative monitoring will occur during a measurable storm event (NCGI50000, Part III). The following outline the qualitative monitoring requirements: • Visual inspections will be performed concurrently with required analytical monitoring (NCG080000). • Visual inspections are not required to be performed outside of the facility's normal operating hours. • Visual inspections will be made at each storm water discharge outfall associated with vehicle and aircraft maintenance facilities unless representative outfall status specifically for visual monitoring has been approved in writing by the Division. • Inability to perform inspections because of adverse weather or lack of discharge during the monitoring period will not constitute a failure to monitor if the event is documented in the SWPPP and recorded on the Qualitative Monitoring Report. • When qualitative monitoring indicates that the SWPPP and/or existing storm water Best Management Practices are ineffective, or that significant storm water contamination is present, the installation will investigate potential causes, evaluate the feasibility of corrective actions, and implement those feasible corrective actions within 60 days. • A written record of the installation's investigation, evaluation, and response actions will be kept in the Storm Water Plan or in Enforcement Actions, Spills, and Inspections Environmental Reporting (EASIER). Seymour Johnson AFB will record the required qualitative monitoring observations on the storm water discharge outfall Qualitative Monitoring Report form provided by the Division and will retain the completed forms on site. Visual monitoring results should not be submitted to the Division, except upon the NCDEQ's specific requirement to do so. The inability to monitor because of adverse weather conditions or lack of discharge during the monitoring period must be documented in the SWPPP and recorded on the Qualitative Monitoring Report. Qualitative sampling forms are included in Appendix C. 4.3.3 Non -Storm Water and Illicit Discharge Survey The Illicit Discharge Detection and Elimination Program identifies, detects, and eliminates all non - storm water discharges from Seymour Johnson AFB's Municipal Separate Storm Sewer System. Target pollutants include total petroleum hydrocarbons (fuels and oils), foam, nutrients, sewage, sediment, and litter. Illicit discharges are defined as a storm drain that has measurable flow during dry weather conditions containing pollutants and/or pathogens. In accordance with NCS000335, Section H, NCG150000, and NCG080000, Seymour Johnson AFB must re -certify annually that the storm water outfalls have been evaluated for the presence of non -storm water discharges. The Non -Storm Water and Illicit Discharge Survey is not submitted to the NCDEQ, but instead September 2022 FINAL 4-5 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE becomes a part of the Storm Water Plan. The survey is included in Appendix C. All industrial storm water outfalls presented in Figure 4-1 will be surveyed. 4.4 Analytical Test Procedures Analytical test procedures for constituents will conform to applicable regulations (40 CFR Part 136, including modifications associated with the publication of 40 CFR 445). A summary table of analytical test methods for the specified constituents, sample container size, type, number, sample preservation requirements, and sample holding times is provided in Table 4-2.

An example form is presented in Appendix C. Sample packaging and shipping requirements are outlined as follows: 1. Suitable bottles and preservatives are to be used for the samples collected. Add correct preservatives as necessary. Generally, the laboratory will add preservatives when the containers are prepared. Do not rinse out preservatives in the field. 2. Print clearly in waterproof ink or indelible marker on the proper sample stickers the sample identification, data, and the preservatives, if any, that have been added to each sample bottle (refer to Section 5.1.1). 3. Cover the sample labels with clear tape if adhesion to the sample container may be a problem. 4. Close each glass bottle or polyethylene bottle and immediately seal with a chain -of -custody seal. 5. Glass bottles are to be rolled in a bubble pack. Sample bottles are then placed in protective plastic bags upright in the ice chest. Pack enough blue ice or ice in the ice chest to last until the laboratory receives the samples. 6. Seal a copy of each chain -of -custody record inside a sealable plastic bag. Place the sealed plastic bag with the chain -of -custody record in the ice chest (retaining the field copy). 7. Seal the ice chest with tape. Place two custody seals on each ice chest. 8. The laboratory -specified holding time must not be exceeded. 5. L I Sample Bottle Labeling Each sample bottle will include a standard label with a unique discharge monitoring point site - identifiable sample number. Samples will be assigned individual identification letters corresponding to the monitoring point letter and number designation. Samples from each discharge point will be assigned in the general number format followed by the date (e.g., OF 15d 03/03/2023, OF03_03/03/2023). Sample containers are to be labeled with: 1. Time and date of sample collection, 2. Unique sample identification, 3. Sampler's initials, 4. Laboratory analysis required, and 5. Sample preservative, if any. September 2022 FINAL 5-1 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE The preceding information will also be recorded in the Storm Water Sampling Field Log, presented in Appendix C. Field parameters like flow depth and rainfall will be assessed and recorded in the field notes. 5.1.2 Grab Sampling Duplicate manual grab samples will be taken at a given discharge monitoring point for each sampling event as follows: 1. Reasonable attempts will be made to obtain grab samples from the horizontal and vertical center of the discharge. 2. The appropriate laboratory container is held below the water surface with the opening facing upstream. 3. Latex gloves are worn, and care is taken to avoid touching the inside of the container. 4. Samples are kept free of uncharacteristic debris. 5. A second appropriate sample is then taken from the same location. 6. Bottles are capped, sealed with a chain -of -custody seal, placed in plastic bags, and chilled to 4°C (39.2° F). 5.2 Sample Storage and Transport Clean insulated containers used for sample storage will generally be obtained from the laboratory performing the analysis. The samples should immediately be cooled to approximately 4°C (39.2° F). The container should be suitable for shipment of samples to the laboratory following the chain - of -custody procedures outlined in this report. Place containers in polyethylene plastic bags to minimize atmospheric contamination. All samples will be adequately packed and maintained at proper temperatures (i.e., 4°C [39.2° F]) during transport. Transport samples directly to an analytical laboratory to accommodate laboratory -specified holding time(s). 5.3 Chain -of -Custody Chain -of -custody procedures must be followed to ensure and document the validity of the samples. Chain -of -custody can be summarized as knowing who has the sample and where the sample has been from the time of collection until the laboratory analyzes the sample. Field chain -of -custody procedures include inventory and record keeping during sample collection, shipment, and receipt at the laboratory. The field sampler is personally responsible for the care, custody, and shipment of collected samples. In general, a sample is under chain -of -custody control if sample containers are: 1. In the sampler's actual possession 5-2 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE 2. In the sampler's view after being in his/her physical possession 3. Secured in an area so no one can tamper with the sample 4. Secured in an area which is restricted to authorized personnel Sample identification documents must be carefully prepared so that identification and chain -of - custody can be maintained, and sample disposition can be controlled. The sampler must fill out adhesive sample labels and secure them to the sample bottle(s) as outlined in Section 5.1. The information on these labels should correspond to the chain -of -custody record, which shows the identification of individual samples and the contents of the insulated sample container. Insulated sample containers are sealed with custody seals for delivery to the laboratory. Once the laboratory custodian receives the samples, laboratory personnel are responsible for the care and custody of the samples. When transferring sample custody, the individual relinquishing and receiving the samples will sign, date, and note the time on the record to document sample custody transfer.

Storm Water Sampling Field Log 2. NCDEQ Qualitative Sampling Report 3. Non -Storm Water and Illicit Discharge Survey 4. Chain -of -custody records The Consultant Project Manager's responsibility is to ensure these documents are appropriately used, filed correctly, and distributed to the Responsible Party in Table 1-2. 6.2 Data Validation Data validation and reporting procedures for field data will include the following: 1. Checking the calibration procedures/measurements (if any) used during sampling. 2. Comparing the data to previous measurements obtained at the sample location. 3. Reviewing the daily reports for adherence to established protocols. 4. Reviewing the data for completeness and reasonableness. 6.3 Field Quality Control Checks Field quality control refers to the preparation and subsequent analysis of blank and duplicate samples. Field quality control checks refer to the efforts made to evaluate the accuracy, reproducibility, or representatives of the system parameters being measured. Field quality control procedures will be used during storm water sampling events. 6.3.1 Field Blanks Field blanks will be prepared in the field to evaluate if the methods and procedures used to collect the samples result in contamination of the sample. One field blank will be prepared and analyzed for every ten samples or each storm water sampling event. Field blanks will be collected by filling a sampling container specific for the analytical method with distilled water in the field, in the same manner that field samples are collected. 6.3.2 Field Sample Duplicates Field duplicates will be collected during each storm water sampling to evaluate the reproducibility of laboratory data or physical measurements. Field duplicate samples will be prepared by the immediate sequential filling of sample containers at the same sample location. Field duplicates will be labeled with an additional "D" in such a manner to prevent the laboratory from identifying September 2022 FINAL 6-1 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE the sample as a duplicate (e.g., 0F15dD_03/03/2023, OF03D_03/03/2023. Field duplicate samples will be collected for approximately one out of every ten samples. 6-2 FINAL September 2022 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE 7.0 LIMITATIONS This Monitoring Plan is for the use of Seymour Johnson AFB as it applies to the subject site in Wayne County, North Carolina.

Need to Halt or Reduce not a Defense PART K DEFINITIONS Im Permit No. NCG080000 PART A: NCGO80000 PERMIT COVERAGE All persons desiring to have facilities covered by this General Permit must register with the Division of Energy, Mineral, and Land Resources (the Division) by the filing of a Notice of Intent (NOIJ and applicable fees. The NOI shall be submitted and a Certificate of Coverage (COCA issued prior to any discharge of stormwater associated with industrial activity to the surface waters of the state or to a municipal separate storm sewer system (MS4) conveying discharges to surface waters. 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 shall 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 been revoked or rescinded. 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 rescinded 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 NOI form to the Division; must receive approval from 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 is for one or more watersheds with one or more impaired waters. The TMDL sets one or more pollutant -loading limits that affects one or more watersheds, or portion of a watershed, draining to one or more impaired waters. A list of approved TMDLs for the state of North Carolina can be found at https:lldeg.nc.govlabout/divisions/water-resources/planning/modeling-assessment/tmdls. To not be subject to the TMDL, each facility with one or more discharges to watersheds affected by a TMDL must demonstrate it does not have reasonable potential to violate applicable water quality standards for those pollutants identified in the TMDL 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. After that individual permit becomes effective, the facility will no longer have coverage under this General Permit. Although there is not a TMDL for every impaired water, the permittee must identify impaired waters in the General Location Map, as outlined in Part B of this permit. The Department of Environmental Quality - Division of Water Resources integrated reports (https: I Ideq.nc.govlabout/divisions/water-resources/planning/modeling-assessment/water- quality-data-assessment/integrated-report-files) include assessments of waters monitored in North Carolina. Use the most recent final report to identify impaired waters. Until this permit expires or is modified, rescinded, or revoked, the permittee is authorized to discharge stormwater to the surface waters of North Carolina or a MS4 which has been treated and managed in accordance with the terms and conditions of this General Permit and the requirements of the permittee's 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. Page 1 of 35 Permit No. NCG080000 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 discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 213.0230 and .0231 and water quality certification requirements as outlined in 15A NCAC 2H .0500. If industrial activities expand or change after issuance of the COC such that the types of discharges are affected, the permittee must first contact the Division to determine if modifications to the COC are necessary. This permit does not relieve the permittee's responsibility for compliance with any other applicable federal, state or local law, rule, standard, ordinance, order or decree. Page 2 of 35 Permit No. NCG080000 PART B: STORMWATER POLLUTION AND PREVENTION PLAN (SWPPP) The permittee shall develop a Stormwater Pollution Prevention Plan (SWPPP).

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 and must be secured 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 NOI 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 stormwater discharges do not have reasonable potential to violate applicable water quality standards for those pollutants. 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 permiee 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 http: JJportal.ncdenr.orgJweb Jwq [ps /mtu Jtmdl. Part I Page 1 of 2 Permit No. NCG150000 SECTION B: PERMITTED ACTIVITIES 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). All discharges shall be in accordance with the conditions of this permit. The types of authorized discharges are dependent upon DEMLR approval and are detailed in the permittee's individual 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. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 2B .0230 and .0231 and water quality certification requirements as outlined in 15A NCAC 2H .0500. This General Permit does not authorize discharges determined by the Division to be wastewaters. Wash water and rinse water must be directed to a sanitary sewer system or permitted by a separate wastewater permit issued by the Department. 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. NCG150000 PART II STORMWATER POLLUTION PREVENTION PLAN The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). This plan shall be considered public information in accordance with Part V, Standard Conditions, Section E of this General Permit. The SPPP shall include, at a minimum, the following items: A. 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 general location map (USGS quadrangle map or 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 accurate latitude and longitude of the points of stormwater discharge associated with industrial activity. The general location map (or alternatively the site map) shall identify any receiving waters that are impaired (on the state's 303(d) list of impaired waters) or if located in a watershed for which a TMDL has been established, and what the parameters of concern are. 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. A narrative description of the potential pollutants that could be expected to be present in the stormwater discharge from each outfall. 3. A site map drawn at a scale sufficient to clearly depict: the site property boundary; the stormwater and/or wastewater 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 and finished grade; 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. B. A list of significant spills or leaks of pollutants during the previous three (3) years and any corrective actions taken to mitigate spill impacts. C. 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. The certification statement will be signed in accordance with the requirements found in Part V, Standard Conditions, Section B, Paragraph 3. D. 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: 1. 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 Part I1 Page 1 of 4 Pages Permit No. NCG150000 materials and processes to rainfall and run-on 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 run-on away from areas of potential contamination. 2. Secondary Containment Requirements and Records. 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 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 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 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 facilities subject to a federal oil Spill Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan fully compliant with the requirements of this permit may be used to demonstrate compliance with this permit. The Division may allow exceptions to secondary containment requirements for mobile refuelers, as with the exemption provided by amendments to federal SPCC regulations, as long as appropriate spill containment and/or diversionary structures or equipment is used to prevent discharge to surface waters. Exceptions do not apply to refuelers or other mobile tankage used primarily as bulk liquid material storage in a fixed location in place of stationary containers. 3. BMP Summary. A listing of site structural and non-structural 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. E. 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. Facility personnel responsible for implementing the SPRP shall sign and date the SPRP acknowledging their responsibilities for the plan. A responsible person shall be on -site 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. Part II Page 2 of 4 Pages Permit No. NCG150000 F. 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. G. 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 IV B, C, and D of this permit. H. 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 facility personnel responsible for implementing the training shall be identified, and their annual training shall be documented by the signature of each employee trained. I. 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. J. SPPP Amendment and Annual Update. 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. All aspects of the SPPP shall be reviewed and updated on an annual basis. The annual update shall include: 1. 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); 2. a written re -certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges (element of the Site Overview); 3. a documented re-evaluation of the effectiveness of the on -site stormwater BMPs (BMP Summary element of the Stormwater Management Strategy). K. 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 V, Standard Conditions, Section B, Paragraph 3) to the Director that the changes have been made. Part II Page 3 of 4 Pages Permit No. NCG150000 L. Vehicle and equipment cleaning 1. Describe measures that prevent or minimize contamination of the stormwater runoff from areas used for vehicle and equipment cleaning, Perform all cleaning operations indoors, cover the cleaning operations, ensure washwater drains to the sanitary sewer system, or collect stormwater runoff from the cleaning area and provide treatment, recycling, proper disposal, or other equivalent measures. If sanitary sewer is not available to the facility and cleaning operations take place outdoors, the cleaning operations shall take place on grassed or graveled areas to prevent point source discharges of the washwater into the storm drains or surface waters. 2. Where cleaning operations cannot be performed as described above and when operations are performed in the vicinity of a storm drainage collection system, the drain is to be covered with a portable drain cover during cleaning activities. Any excess standing water shall be removed and properly handled prior to removing the drain cover. 3. For facilities that house or operate three or fewer emergency response vehicles staff the permittee shall minimize runoff from vehicle washing shall describe measures that prevent or minimize contamination of the stormwater runoff from areas used for vehicle and equipment cleaning to the maximum extent practicable. 4. vehicle and equipment cleaning areas that drains to an open grass field and infiltrates so there is no discharge is an acceptable practice since there is no discharge. 5. Except as provided above, the point source discharge of vehicle and equipment wash waters, including tank cleaning operations, are not authorized by this permit and must be covered under a separate NPDES permit or discharged to a sanitary sewer in accordance with applicable industrial pretreatment requirements. M. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan and all appropriate BMPs consistent with the provisions of this permit, 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 five (5) years and made available to the Director or the Director's authorized representative upon request. Part II Page 4 of 4 Pages Permit No. NCG150000 PART III 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 outfalls must be performed during a measurable storm event. Qualitative monitoring shall be performed as specified in Table 1. Monitoring results shall be recorded on the Qualitative Monitoring Report forms available from the Division's website. Completed forms shall be maintained on site with the SPPP. Table 1 Qualitative Monitoring Requirements Discharge Characteristics Frequency' Monitoring Locationz Color Semi -Annual SDO Odor Semi -Annual SDO Clarity Semi -Annual SDO Floating Solids Semi -Annual SDO Suspended Solids Semi -Annual SDO Foam Semi -Annual SDO Oil Sheen Semi -Annual SDO Erosion or deposition at the outfall Semi -Annual SDO Other obvious indicators of stormwater pollution Semi -Annual SDO Footnotes: 1 Monitoring Frequency: Twice per year (unless other provisions of this permit prompt other frequency) during a measureable storm event. 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. Monitoring must begin within the first 30 minutes of discharge,. Qualitative Monitoring Response 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 institute analytical sampling for suspect chemical and physical parameters • increase the frequency of qualitative monitoring; • 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 Part III Page 1 of 2 Pages Permit No. NCG150000 Inability to monitor because of adverse weather conditions 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 SDOs discharging stormwater associated with industrial activity must be monitored (See Definitions). Part III Page 1 of 2 Pages Permit No. NCG 150000 PART IV DEICING OPERATIONS Airports that conduct aircraft and/or runway (including taxiways and ramps) deicing/anti-icing operations shall maintain a record of annual usage rate of deicing/anti-icing chemicals. The Division may require airports that conduct aircraft and/or runway (including taxiways and ramps) deicing/anti-icing operations (other than for emergency reasons) to apply for an individual permit if the usage is determined to be a common practice.

Industrial Activity: For the purposes of this permit, industrial activities shall mean all industrial activities as defined in 40 CFR 122.26. 11. Major Municipal Separate Storm Sewer Outfall (or "Major Outfall"'): Major municipal separate storm sewer outfall (or "major outfall") means a municipal separate storm sewer outfall that discharges from a single pipe with an inside diameter of 36 inches or more or its equivalent (discharge from a single conveyance other than circular pipe that is associated with a drainage area of more than 50 acres); or for municipal separate storm sewers that receive storm water from lands zoned for industrial activity (based on comprehensive zoning plans or the equivalent), an outfall that discharges from a single pipe with an inside diameter of 12 inches or more or from its equivalent (discharge from other than a circular pipe associated with a drainage area of 2 acres or more). 12. Maximum Extent Practicable (MEP): MEP is defined in the Federal Register (U.S. EPA, 1999, p. 68754). This document says that "Compliance with the conditions of the general permit and the series of steps associated with identification and implementation of the minimum control measures will satisfy the MEP standard." Minimum control measures are defined in the Federal Register as (1) public education and outreach, (2) public participation/involvement, (3) illicit discharge detection and elimination, (4) construction site runoff control, (5) 18 of20 PERMIT NO. NCS000335 post -construction runoff control, and (6) pollution prevention/good housekeeping. MEP are the controls necessary for the reduction of pollutants discharged from a MS4, which consist of a combination of BMPs, control techniques, system design and such other provisions as described in the SWMP. Implementation of BMPs consistent with the provisions of the stormwater management program required pursuant to this permit constitutes compliance with the standard of reducing pollutants to the MEP. Stormwater management programs must be assessed and adjusted, as part of an iterative process, to maximize their efficiency and make reasonable progress toward as ultimate goal of reducing the discharge of pollutants to the MEP. 13. Municipal Separate Storm Sewer System (MS4): Pursuant to 40 CFR 122.26(b)(8) means a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains) owned or operated by the United States, a State, city, town, county, district, association, or other public body (created by or pursuant to State law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under State law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under Section 208 of the Clean Water Act (CWA) that discharges to waters of the United States or waters of the State that is designed or used for collecting or conveying stormwater; that is not a combined sewer; and which is not part of a Publicly Owned Treatment Works (POTW) as defined in 40 CFR 122.2. 14. Non-structural BMP: Non-structural BMPs are preventive actions that involve management and source controls such as: (1) Policies and ordinances that provide requirements and standards to direct growth to identified areas, protect sensitive areas such as wetlands and riparian areas, maintain and/or increase open space, provide buffers along sensitive water bodies, minimize impervious surfaces, and/or minimize disturbance of soils and vegetation; (2) policies or ordinances that encourage infill development in higher density urban areas, and areas with existing storm sewer infrastructure; (3) education programs for developers and the public about minimizing water quality impacts; (4) other measures such as minimizing the percentage of impervious area after development, use of measures to minimize directly connected impervious areas, and source control measures often thought of as good housekeeping, preventive maintenance and spill prevention. 15. Outfall: Outfall means a point source as defined by 40 CFR 122.2 at the point where a municipal separate storm sewer discharges to waters of the United States and does not include open conveyances connecting two municipal separate storm sewers, or pipes, tunnels or other conveyances which connect segments of the same stream or other waters of the United States and are used to convey waters of the United States. 16. Permittee: The owner or operator issued this permit. 17. Point Source Discharge of Stormwater: Any discernible, confined and discrete conveyance including, but not specifically limited to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which stormwater is or may be discharged to waters of the state. 18. Redevelopment: "Redevelopment" has the same meaning as in G.S. 143-214.7. 19. Storm Sewer System: Is a conveyance or system of conveyances which are designed or used to collect or convey stormwater runoff that is not part of a combined sewer system or treatment works. This can include, but is not limited to, streets, catch basins, pipes, curbs, gutters, ditches, man-made channels or storm drains that convey stormwater runoff. 20. Stormwater Associated with Industrial Activity: The discharge from any point source which is used for collecting and conveying stormwater and which is directly related to manufacturing, processing or raw material storage areas at an industrial site. Facilities considered to be engaged in "industrial activities" include those activities defined in 40 CFR 122.26(b)(14). The term does not include discharges from facilities or activities excluded from the NPDES program. 19 of 20 PERMIT NO. NCS000335 21. Stormwater Control Measures (SCM): "Stormwater Control Measure" or "SCM," also known as a structural "Best Management Practice" or "BMP," means a permanent device that is designed, constructed, and maintained to remove pollutants from stormwater runoff by promoting settling or filtration; or to mimic the natural hydrologic cycle by promoting infiltration, evapo-transpiration, post -filtration discharge, reuse of stormwater, or a combination thereof. 22. Stormwater Management Program: The term Stormwater Management Program refers to the comprehensive stormwater management program that is required to be developed and implemented by MS4 permittees. 23. Stormwater Management Plan (SWMP): The Stormwater Management Plan is the written plan that is used to describe and define the various control measures and activities the permittee will undertake to implement the stormwater management program to meet the MEP standard. 24. Stormwater Runoff. The flow of water which results from precipitation and which occurs immediately following rainfall or as a result of snowmelt. 25. Total Maximum Daily (TMDL): A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed water quality assessment that provides the scientific foundation for an implementation plan. The implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to restore and maintain water quality standards in all seasons. The Clean Water Act, Section 303, establishes the water quality standards and TMDL programs. 26. Waste Load Allocation (WLA): A WLA is a TMDL pollutant reduction target allocating a specific load reduction to specific point source discharge(s) of the pollutant. Some stormwater point source discharges are assigned a WLA. 20 of 20 BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE APPENDIX B LARGE FORMAT SITE MAP BASE -WIDE MONITORING PLAN SEYMOUR JOHNSON AIR FORCE BASE This page intentionally left blank.
