The Storm Water Plan provides procedures for managing storm water discharges from Seymour Johnson AFB (SJAFB) industrial facilities, construction sites (greater than 1 acre), and from oil water separators not associated with wastewater discharges to receiving waters in the Neuse River Basin. State waters described in this plan are identified as Stoney Creek, Hospital Creek, Burge Ditch, Mayfield's Ditch, Prison Ditch, Golf Course Ditch, and Golf Course Lake. This Storm Water Plan (SWP) was prepared to meet all requirements of the North Carolina Department of Water Quality, Division of Energy, Mineral, and Land Resources, National Pollutant Discharge Elimination System (NPDES) Permit # NCS000335 to discharge storm water from the SJAFB to waters of the state (refer to Appendix A). In accordance with NPDES Permit NCS000335, Part I, this SWP will: a. Provide tables to identify each best management practice (BMP) used, frequency of the BMP, measurable goals for each BMP, Implementation Schedule, funding, and the responsible person or position for implementation (see Appendix H). b. Serve as the planning document and directive to be used by military personnel, civilian staff, contractors, and members of the general public at Seymour Johnson AFB who have access the base. c. Function as a living document that is amended to address changes in industrial discharges or processes. Any point discharge to surface waters of the state is prohibited unless it is an allowable non -storm water discharge or is covered by another permit authorization or approval. d. Define and detail a 5-year schedule for Storm Water Management Program implementation and a narrative description of the program (see Appendix H). e. Address current and future status of activities associated with industrial storm water discharges and reduces the discharge of pollutants from the base to the maximum extent practicable (see Appendix H). 1.2 Regulatory Background L Z I Phase I NPDES Program In 1972, the NPDES program was established under the authority of the Clean Water Act. In November 1990, federal storm water discharge requirements (known as the Phase I NPDES Program) were promulgated as part of the NPDES under the Clean Water Act (55 Federal Register 48062-48901). These regulations, as stated in 40 Code of Federal Regulations (CFR) Parts 122, 123, and 124, require the owners of "facilities that discharge storm water associated with industrial activity" to apply for a storm water permit if storm water is discharged to: (1) waters of the United States or (2) municipal separate storm sewer systems (MS4s). A facility is subject to the regulations only if its activities fit the definition of Storm Water Plan 1-1 Seymour Johnson AFB "industrial" as specified by the 11 categories in 40 CFR 122.26(b)(14)(i)-(xi). These categories constitute the definition of industrial activity. If a discharger does not fit the requirements for any of the categories a storm water permit is not required. Five of the categories are defined relative to Standard Industrial Classification (SIC) codes and the remaining six categories are defined descriptively. The General Permit incorporates the definition of industrial activity from 40 CFR 122.26. NPDES permits are issued either by a US Environmental Protection Agency (EPA) Regional office or by states that have been granted NPDES permitting authority. Seymour Johnson AFB is located in the State of North Carolina, which has NPDES permitting authority. The North Carolina Department of Environment Quality, Division of Energy, Mineral, and Land Resources administers the state's NPDES. The EPA has defined 11 categories of industrial activity that are subject to this regulation. The primary SIC Classification for Seymour Johnson AFB is 4581 - "establishments primarily engaged in operating and maintaining airports and flying fields; in servicing, repairing, maintaining, and storing aircraft; and in furnishing, coordinating, and handling services for airfreight or passengers at airports". Current industrial activities at the base fall primarily within the EPA -defined category viii (see below) are limited to portions of the base involved in aircraft and vehicle maintenance. The following excerpt from CFR Volume 40, Part 122, and EPA Administered Permit Programs: The NPDES, Subpart A, Section 26, describes the regulated activities: "(14)(viii) Transportation facilities classified as Standard Industrial Classifications 40, 41, 42 (except 4221-25), 43, 44, 45 and 5171 which have vehicle maintenance shops, equipment cleaning operations, or airport deicing operations. Only those portions of the facility with applicable SIC codes that are either involved in vehicle maintenance (including vehicle rehabilitation, mechanical repairs, painting, fueling, and lubrication), equipment cleaning operations, or areas where airport de-icing occurs, or which are otherwise identified under paragraphs (b)(14) (i)-(viii) are identified and associated with an industrial activity." "(14) (X) Construction sites that disturb 5 acres or more (permitted separately)" Section 11 describes industrial activities which have exclusions to stormwater permitting rules. 1.2.2 Other Regulatory Requirements NPDES Permit NCS000335, Section H, requires SJAFB to comply with the requirements of the NC General Permit NCG080000: to control storm water from point source discharges associated with industrial activities that have vehicle maintenance areas or activities (including vehicle rehabilitation, mechanical repair, painting, fueling, lubrication, equipment cleaning operations) and like activities deemed by DWQ to be similar in process and/or the exposure of raw materials, products, by-products, or waste materials. Sanitary sewer wash water from steam cleaning operations or other equipment cleaning operations (including tank cleaning) 1-2 and Transportation by Air (SIC 45) are excluded and not authorized under this permit and are handled by other permits (Goldsboro's Sanitary Sewer Use Ordinance). NCG080000, as with similar requirements in NCG15, also requires: • Implement the Stormwater Plan (Part II, Section A) with the authority to implement all provisions of the Stormwater Plan. • A list of significant spills or leaks of pollutants during the previous (3) years and any corrective actions taken to mitigate spill impacts. List of significant spills are added to the Non-Stormwater and Illicit Discharge Survey and recorded in the Air Force SIRIS Database. Spill locations have also been entered on the base GIS map. • 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 presences of non-stormwater discharges. A Non- Stormwater and Illicit Discharge Survey is competed annually and is added in Appendix C of the Storm Water Plan. • Records documenting releases from secondary containment structures at vehicle maintenance areas (individual making observations, description of storm water, date/time of release). Secondary containment discharge records at SJAFB are maintained at each individual shop that releases uncontaminated water from secondary containment structures. A list of each secondary containment areas for bulk storage of liquid materials is located on the base GIS system map. Also, Appendix 13-1 provides a copy of SPCC containment storm water release form. Manual releases of rainwater from secondary containment structures are documented as required and in accordance to the base SPCC Plan -Appendix C.2.4th CES/CEI also records spills in Microsoft Access Database. • Narrative Description of BMPs used for vehicle maintenance activities and measures to minimize contamination. SJAFB directs all cleaning operations at government vehicle maintenance facilities to be completed indoors and all discharges from maintenance activities to go to the base sanitary sewer system. Spill Prevention, Control, and Countermeasures Plan (SPCC) will be initiated to control and regulate spills (absorbents, spill pans, booms, etc) and minimize releases from oil water separators, fueling operations, vehicle maintenance, and secondary containment areas discharging to storm. Oil water separators are on a pump -out and cleaning schedule and are maintained by a service contract. Oil water separators are inspected by the shops owning OWS and periodically by the 4th CES Utility Shop Oil Water Separator Manager — via contract. Records of contractor inspections are reviewed and maintained by 4th CES Utility Shop OWS Mgr. In addition, wherever practical, the base will prevent exposure from rainfall to all storage areas, material handling operations, and fueling operations. In Lieu of complying with the requirements of paragraph 2 of Section H of the NPDES Permit NCS000335, SJAFB has provided the state and EPA the status of its Stormwater Plan and Monitoring Plan and the status of the storm water program via its annual reports. SJAFB will proceed with the analytical monitoring requirements stipulated in Section J of the NPDES Permit. Because SJAFB did not exceed any required cutoff concentrations limits required in Section J (2c)of the permit in 2016; therefore, SJAFB does not have to complete any additional sampling for those parameters for the remaining term of the permit. NCG080000 excludes Storm Water Plan 1-3 Seymour Johnson AFB vehicle maintenance areas at activities classified as Transportation by Air (SIC 45) and wash water from steam cleaning operations or other equipment cleaning operations. Vehicle and equipment cleaning is directed to be completed "in doors" at on base wash racks that discharge to the base sanitary sewer system. The point source discharge of vehicle and equipment washing to storm water is not authorized by NCG080000 and must be covered by a separate NPDES permit (most likely for sewer discharge). AFI 32-1067 (Section 2.9.2.2.2.2) provides the Installation Management Flight (CEI) the authority and instructions to ensure the installation is in compliance with all water quality permits. It requires CEI to establish local procedures and provide technical expertise regarding water quality management requirements. This Storm Water Plan provides the procedures for SJAFB to comply with all requirements of NPDES Permit NCS000335. NPDES Permit NCS000335, Section H, requires SJAFB to comply with the requirements of the General Permit # NCG150000, Part II, 4(b) 2 which is applicable to facilities that conduct aircraft deicing/anti-icing operations and industrial facilities with point source discharges from Air Transportation Facilities (SIC Code 45). The NPDES Permit NCG150000 (Section C - Deicing Operations) requires the base to: • 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. • Evaluate whether excessive application of deicing chemicals occurs and adjust as necessary, consistent with considerations of flight safety. • The base must also determine annual usage rate of deicing/anti-icing chemicals and report usage rate to the state (see Appendix B-2). • Produce and implement a plan for the minimization of the release of materials used for deicing into the stormwater system. This plan shall address, as a minimum: a. The current use and practices employed at the airport for the control and minimization of entry of the deicing materials into the stormwater system; b. 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 deicing materials; and c. 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 commercial 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. • Annual usage rate of deicing/anti-icing chemicals shall be reported annually to the state. The Division may require facilities that conduct aircraft and/or runway (including taxiways and ramps) deicing/anti-icing operations to apply for an individual permit. SJAFB has evaluated the use of anti -icing and deicing use on the base by reviewing past stormwater sampling reports, locations, and quantities of chemicals used. To control the use of 1-4 deicing chemicals, there are only two locations where aircraft are directed to be deiced on SJAFB - KC135 Ramp and the F-15 Apron (on pavement). Flight line personnel are required to contact the Water Quality Manager (4th CES/CEI) after use of deicing and anti -icing fluid (Propylene Glycol - HOC Industries - NSN 6850-01-435-6465). CE Heavy Repair uses Safeway SF Runway Deicer product (Sodium Formate with inhibitor - NSN: 6850-01-435- 6473) for deicing runways and taxiways. This is a good deicer because it produces very a low biological oxygen demand (BOD5). Deicing chemicals are stored at the snow barn Building 3300, Building 3507, and on the east side of Building 4909. Prior to the issuance of the 2011 NPDES SJAFB stormwater runoff was monitored for the presence of glycol following each deicing event at outfall 2. Because the sample results showed very little evidence of deicing chemical runoff at outfall 2 the state did not require SJAFB to sample for deicing chemicals in the 2018 NPDES Permits. The annual usage rates for deicing and anti -icing chemicals are listed in the table below. Since 2011, deicing chemical quantities at SJAFB have been used very sparingly and not excessive, only on impervious surfaces, and at two locations F 15 and KC 135 Ramp areas. The following table presents anti -icing and deicing chemicals usage and locations at SJAFB.

The permittee shall re -certify annually that the storm water outfalls have been evaluated for the presence of non -storm water discharges (see Appendix C). The certification statement will be signed in accordance with Part III, General Conditions, Section B, Paragraph 5 of the permit and include: • Date of testing and/or evaluation. Visual sampling must be made during daylight hours (Part II, Section B, 2(a)). Visual Monitoring shall be documented and records maintained at the facility. Non -Storm Water and Illicit Discharge Survey will be completed during the qualitative sampling and monitoring periods and placed in Appendix C of the SWP. Storm Water Plan 1-5 Seymour Johnson AFB • Description of evaluation criteria or testing method. Semi -Annual Visual Monitoring documented on similar forms provided by the DWQ and placed in Appendix E of the SWP. • List of the outfalls or onsite drainage points that were directly observed during the test. Qualitative and Quantitative Analysis results of outfall inspections are included in the SWP in Appendix E. • Description of the results of any test or evaluation for the presence of non -storm water discharges (origin, composition). Qualitative sampling results are included in Appendix E of the SWP. • Actions taken to eliminate unauthorized discharge(s) if any were identified. For example floor drain sealed, sink drain rerouted to sanitary. Corrective action plans to eliminate unauthorized discharges will be included in Non -Storm Water and Illicit Discharge Survey and tracked in the Illicit Discharge Spill database. • List and narrative identifying each area where industrial materials or activities are exposed to stormwater and potential pollutants. Areas include locations of raw materials, material handling equipment, industrial machinery, and storage, loading and unloading, disposal, and waste products. Locations of storage piles containing salts for deicing. The base GIS Map will list locations and of areas exposed to storm water and locations used to store salts and deicing chemicals. AF132-1067, Section 4.3.1.4. Requires Air Force installations shall conduct cross -connections and illicit discharge inspections/elimination/construction/repair. An illicit discharge is an unlawful act of disposing, dumping, spilling, emitting, or other discharge of any substance other than storm water into the storm water drainage system. Fuel spills to the storm water system can be a violation of the base SPCC Plan and SWP if not properly clean up and/or reported in a timely manner. Actions including stop work orders, administrative penalties, or NOVs could result if procedures are not properly followed. There is also another activity at that the base that falls under the industrial activity requirement: "(b) (14) (x) Construction activity including clearing, grading and excavation, except operations that result in disturbance of less than five acres of total land area. Construction activity also includes the disturbance of less than five acres of total land area that is a part of a larger common plan of development or sale if the larger common plan will ultimately disturb five acres or more." The NC General NPDES Pesticide Permit NCG 560000 applies to SJAFB pest management operators that discharge to waters of the state from the application of (1) biological pesticides or (2) chemical pesticides that leave a residue when the pesticide application is for one of the following pesticide use patterns: a. Mosquito and Other Flying Insect Pest Control - to control public health/nuisance and other flying insect pests that develop or are present during a portion of their life cycle in or above standing or flowing water. Public health/nuisance and other flying insect pests in this use category include but are not limited to mosquitoes and black flies. 1-6 b. Aquatic Weed and Algae Control - to control invasive or other nuisance weeds and algae in water and at water's edge, including irrigation ditches and/or irrigation canals. c. Aquatic Nuisance Animal Control - to control invasive or other nuisance animals in water and at water's edge. Aquatic nuisance animals in this use category include, but are not limited to fish, lampreys, and mollusks. d. Forest Canopy Pest Control - aerial application of a pesticide over a forest canopy to control the population of a pest species (e.g., insect or pathogen) where to target the pests effectively a portion of the pesticide unavoidably will be applied over and deposited to water. An NOI provides notice of an operators' intent for discharges from its pesticide application activities to be covered under this permit. Coverage is for the operator who filed the NOI, including its employees, contractors, subcontractors, and other agents, for all activities identified on the NOI for the duration of the permit unless coverage is terminated. The following operators are required to submit a Notice of Intent to obtain coverage under this general permit for discharges to waters of the U.S. resulting from the application of pesticides: a. If you are in control over the financing for, or over the decision to perform pest control activities that will result in a discharge and know or reasonably should have known that those activities will exceed one or more of the annual (i.e., calendar year) treatment area thresholds listed in Table 1-1 below for the "treatment area", or b. If you apply pesticides that result in a discharge and know or reasonably should have known that those activities will exceed one or more of the pesticide application annual (i.e., calendar year) treatment area thresholds listed in Table 1-1 below for the "treatment area," as defined in the permit. To determine whether an entity's activities will exceed one or more of the annual treatment area thresholds, the entity should exclude from its calculation any pesticide application activities conducted under another entity's NOI required under (a) above.

Timing for NOI submittal is based on when an operator is aware or reasonably should be aware through consideration of past experience, planned activities, planning, and other analyses, that it will exceed an annual treatment area threshold during the calendar year, not on the time when the threshold is actually exceeded. You must monitor the amount of pesticide applied to ensure that you are using the lowest amount to effectively control the pest, consistent with reducing the potential for development of pest resistance. All applicators covered under this permit must conduct spot checks in the area to and around where pesticides are applied for possible and observable adverse incidents as defined in Appendix A of the permit. If you are required to submit a NOI the base will be required to prepare a Pesticide Discharge Management Plan which will be kept up to date at the base. Contents of the plan can be found in Section 5 of the NPDES Permit NCG560000 in Appendix D of the SWP. The office responsible for SJAFB pesticide management is the 4th CES/ CEOIE Pest Management. Seymour Johnson AFB relies on the NCDENR Division of Land Resources (DLR) to implement the Phase II Construction Site Minimum Measure (Appendix H (4) of SWP). a. The NCDENR Division of Land Resources Erosion and Sediment Control Program via the state General Construction Permit NCG010000 (Refer to Appendix D) effectively meets the requirements of the Phase II Construction Site Runoff Controls Minimum Measure 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. The NCDENR Division of Land Resources Erosion and Sediment Control 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 1-8 which incorporates consideration of potential water quality impacts, and procedures for site inspection and enforcement of control measures. b. The permit NCG010000 (Appendix D of SWP) also 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. The permit additionally requires: (1) Ground cover to be in place within 14 days on disturbed flat areas and 7 days of temporary or permanent stopping of work on "all perimeter dikes, swales, ditches, perimeter slopes and all slopes steeper than 3 horizontal to 1 vertical." (2) Permit requires designated areas for debris, construction waste, earthen stock piles, concrete washouts, and other wastes to be located "at least 50 feet away from storm drain inlets and surface waters." Liquid and solid wastes from washout operations must be contained in leak -proof containers. Cement truck washouts are allowed only in designated areas and labeled with a sign. (3) On -site pits are only allowed if designed to handle the waste volume and approved by agency. (4) Visible deposition of sediment off -site and to state waters must be reported to DWQ within 24 hours of inspections. Written submission shall be provided to DWQ within 5 days of the time the permittee becomes aware of circumstances. (5) Rain gauge shall be maintained on site. Inches of rainfall documented. (6) Written record of rainfall amounts shall be retained. If not rainfall occurred, record "zero" (7) At least once every seven calendar days each control measure and outfall shall be inspected to ensure proper operations, no sediment discharges, and records maintained. Inspections shall be made within 24 hours of 0.5 inch rain event. (8) Storm water discharges shall be observed and recorded. Self inspections continue to be a part of the permit but will only be required during "normal business hours." (9) Sedimentation/Erosion Plans must be approved before disturbance occurs. (10) Records of inspections during the previous 30 days shall remain on the site for agency inspections at all times during normal working hours unless exempted. (11) Once land disturbance begins, stormwater runoff discharge outfall shall be inspected for evidence of erosion, sedimentation and other stormwater discharge characteristics such as clarity, floating solids, and oil sheens. Inspections are required only during normal business hours. Twenty-four hour reporting for visible sediment deposition in state waters. Storm Water Plan 1-9 Seymour Johnson AFB Sedimentation and Control Act Self -Inspection Program. Effective October 1, 2010, the Sedimentation and Control Act was amended to require that persons responsible for land -disturbing activities larger than one acre to inspect a project after each phase of the project to make sure that the approved erosion and sedimentation control plan is being followed. The self -inspection program is separate from the weekly self -monitoring program of the General NPDES Storm Water Permit NCGO10000 for Construction Activities. The focus of the self -inspection report is the installation and maintenance of erosion and sedimentation control measures according to the approved plan. The inspections should be conducted after each phase of the project, and continued until permanent ground cover is established. All erosion control measures (sedimentation control basins, sedimentation traps, sedimentation ponds, rock dams, temporary diversions, temporary slope drains, rock check dams, sediment fence or barriers, all forms of inlet protection, storm drainage facilities, energy dissipaters, and stabilization methods of open channels must be inspected. A "Self -Inspection Report for Land Disturbing Activity as required by NCGS113A-54-1" can be used or an alternative Excel spreadsheet. Documentation shall be accomplished by initialing and dating each measure or practice shown on a copy of the approved erosion and sedimentation control plan or by signing the inspection report. This report does not have to be done weekly but after each completed phase of the approved erosion and control plan. Phases include: • Installation of perimeter erosion and sedimentation control measures; • Clearing and grubbing of existing ground cover; • Completion of any phase of grading of slopes or fills; • Installation of storm water drainage facilities; • Completion of construction or development; and • Establishment of permanent ground cover sufficient to restrain erosion. To simplify documentation of Self -Inspection Reports and NPDES Self -Monitoring Reports, a combined form is available. The new form satisfies the requirements of the Sedimentation Pollution Control Act and the NPDES Stormwater Permit for Construction Activities, NCG 010000. Beginning August 1, 2013, the Division of Energy, Mineral, and Land Resources is responsible for administering both the SPCA and the NPDES Stormwater Permit for Construction Activities, NCG 010000. The form can be found and downloaded at: hgps:Hfiles.nc. gov/ncdeq/Energy+Mineral+and+Land+Resources/Land+Resources/Land+Qualit y/Combined+Construction+Stormwater+Monitoring+Form/DEMLR%20C S W %20Monitoring% 20Form%20Rev%2008012013.FINAL.pdf. Any construction activities that have an E&SC Plan approved on or after April 1, 2019 are required to fill out and submit an electronic Notice of Intent (e-NOI) form at the link below. All construction activities are required to follow the new NCGO 1 permit regardless of when they 1-10 were approved. The new permit and the two standard detail sheets (or similar) shall be available at every construction site. e-NOI form (live as of April 2, 2019) Engineering Technical Letter (ETL) 14-1: Construction and Operation and Maintenance Guidance for Storm Water Systems (7 August 2014). The ETL provides procedures and practices for minimizing storm water pollution from Air Force construction activities, guidance for construction inspectors regarding temporary sediment and erosion controls, operations and maintenance (O&M) guidance for storm water infrastructure (i.e separate storm sewers, associated appurtenances, and drainage areas), and permanent storm water best management practices (BMP). Spill Prevention Control and Countermeasures Plan Seymour Johnson AFB has prepared its SPCC plan per EPA's Oil Pollution Prevention regulation, 40 CFR 112. Under 40 CFR 112, facilities must detail and implement spill prevention and control measures in their SPCC Plans for all oil/fuel storage areas/equipment. 1.2.3 Phase H NPDES Program Phase H of the NPDES Storm Water Program was signed into law in December 1999. This regulation builds upon the existing Phase I program by requiring smaller communities, also known as MS4s, to be permitted. SJAFB has been designated as a "NPDES Permit - Phase I MS4/Military" facility. MS4s permitted under Phase II are required to develop and implement a comprehensive storm water management program that includes six minimum measures: (1) Public education and outreach on storm water impacts; (2) Public Involvement/Participation; (3) Illicit discharge detection and elimination; (4) Construction Site Storm Water Runoff Control; (5) Post - Construction Storm Water Management for new development and redevelopment; and (6) Pollution Prevention/Good Housekeeping for municipal operations. Under the new NPDES Permit Seymour Johnson AFB is considered a small MS4 and is now regulated under the Phase I MS4/Military NPDES program. Session Law 2006-246 (Senate Bill 1566), Section 9(b, provided for the implementation of the Federal Phase II Storm Water requirements in North Carolina for post -construction requirements. The Law and the base NPDES Permit require SJAFB to implement its Watershed Protection Plan, approved by the state, to meet its post - construction stormwater minimum measure. Storm Water Plan 1-11 Seymour Johnson AFB 1.3 Program Management 1.3.1 Implementation Authority Base -wide orders to implement this SWP and the aspects of the Storm Water Management Program are established in Air Force Instructions (AFI) 32-1067- Water and Fuel Systems; Engineering Technical Letter (ETL) 03-1 Storm Water Construction Standards, and ETL 14-1 Construction and Operation and Maintenance Guidance for Storm Water Systems. The Office of Primary Responsibility for this SWP document is the Installation Management Flight, 4 CES/CEI. The storm water NPDES Permit NCS000335 (Part II, Section A, 1) requires Seymour Johnson to "develop and maintain a Storm Water Plan with the authority to implement all provisions of the Storm Water Program." In addition to this base -specific order, the following Air Force guidance documents are applicable to the implementation of the program: ➢ Air Force Instruction (AFI) 32-1067, Water and Fuel Systems, 4 February 2015 - This AFI implements AFPD 32-70, Environmental Quality, and provides details of the Air Force Water Quality Compliance Program. This AFI also mandates that a water quality compliance program be established at all Air Force installations. ➢ Executive Order 13514: Federal Leadership in Environmental, Energy, and Economic Performance, October 5, 2009 - directed the EPA to issue EISA Section 438 guidance and ensure new construction and major renovations meet Guiding Principles. ➢ DUSD Memorandum: DOD Implementation of Storm Water Requirements under Section 435 of the Energy Independence and Security Act,19 Jan 2010 — Requires post -construction analysis be conducted and design cost to implement EISA 438. ➢ Engineering Technical Letter (ETL) 03-1: Storm Water Construction Standards - This ETL prescribes procedures and practices to eliminate or minimize storm water pollution resulting from Air Force construction activities. ETL establishes Air Force mandatory requirements for soil and erosion control at construction sites and requires implementation of Best Management Practices (BMPs) and pollution prevention measures to achieve compliance with all applicable local, state, or federal regulation. ➢ Engineering Technical Letter (ETL) 14-1: Construction and Operation and Maintenance Guidance for Storm Water Systems — provides procedures for minimizing storm water pollution from construction sites. Defines a "Federal Facility" as a building that is constructed, renovated, leased, or purchased in part or in whole for use by the Federal Government. "Building," defined by DODI Real Property Inventory and Forecasting, pg9, is a roofed and floored facility enclosed by exterior walls and consisting of one or more levels suitable for single or multiple buildings. ETL 14-1 states that a project involving a federal facility that does not include a building structure is not applicable for EISA Section 438, e.g. runway repair projects, runway extension projects, road rehab or extension/construction. If there is no building work, EISA does not apply. However, public transportation projects > 1 acre maintained by SJAFB are required to be tracked IAW the SJAF13 NPDES Permit NCS000335. 1-12 1.3.2 Program Prioritization NPDES Permit No. NCS000335, Part H, Section A (2) states that it is anticipated in order to reduce pollutants to the "maximum extent practicable"; Seymour Johnson will implement its SWP with an 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 following are components of the Seymour Johnson's storm water management program and their respective prioritization: Priority 1 - Maintain adequate funding and staffing to implement and manage the provisions of the plan (Part H, Section A (3)). Priority 2 - Implement programs to address the contribution of pollutants to the storm drainage system from industrial areas including six minimum measures (Part H, Section A (4)). Priority 3 - Implement components of the plan to prohibit, to the maximum extent practicable, illicit connections, spills, and illegal dumping (Part H, Section A (5)). Priority 4 - Implement provisions to monitor and assess the performance of the various management measures of the SWP (Part H, Section A (6)). Priority 5 - Implementation appropriate education, training, outreach, and public involve programs to support the objectives of the storm water discharge permit and SWP (Part H, Section A (7)). Priority 6 - Implement a program to reduce pollution from construction site runoff as described in the SWP and in accordance with the permit (Part H, Section A (8)). Priority 7 - Implement a monitoring program as described in the permit. Monitoring will be used to assess the effectiveness of program components and modify program components as necessary (Part H, Section A (9). Each of these program priority components are discussed in detail throughout the text of this SWP. The first four sections of the SWP contain: • Introduction - Discussion of the purpose of the SWP and regulatory background; • SWPPT - Storm Water Pollution Prevention Team membership; • Plan Maintenance - Discussion of how the plan will be updated, annual reports ; • Site Plan - General Base Description, Topography, Drainage Basins, Outfalls, Authorized Discharges, Spill Prevention Procedures, Sanitary Sewer Overflow Guidance, and Training; Storm Water Plan 1-13 Seymour Johnson AFB The next six sections describe the Phase II Six Minimum Measure Goals and Status: Section 5 - Public Education and Outreach (see Appendix H for measures, goals, and status); Section 6 - Public Involvement and Participation (see Appendix H for measures, goals, and status); Section 7 - Illicit Discharge and Elimination (see Appendix C for non -storm water & illicit discharge survey and Appendix H for measures, goals, status, and training info); Section 8 - Construction Site Storm Water Management (see Appendix D for information on NPDES General Construction Permit NCGO 10000); Section 9 - Post -Construction Site Runoff Controls (see Appendix H for measures, goals, and status); and Section 10 - Pollution Prevention and Good Housekeeping (see Appendix H for measures, goals, and status). Also added to the SWP are discussions for Impaired Waters (see Appendix I) and Total Maximum Daily Load requirements (see Appendix J) for SJAFB. NCDEQ MS4 Permit compliance audits will become a regular part of DEMLR's MS4 Program beginning in 2019. Each MS4 will be audited at least once per permit term, typically right before the permit renewal application is developed. All Phase II MS4 audits and self -audits will utilize the MS4 Permit Compliance Audit Report Template, which is part of the MS4 Toolbox currently under development.

AFI 32-1067 requires each Air Force regulated installation to ensure compliance in cooperation with other stakeholders with all water discharge permit conditions including: ➢ Sampling, Analysis, Recordkeeping Inspections, Notice of Intent (NOI) and Notice of Termination (NOT); ➢ Reporting, training, submitting discharge monitoring reports (DMRs) on time by certified mail; and ➢ Submit NPDES permit renewal applications by certified mail, typically 180 days before permit expiration. 2.2 Team Members and Responsibilities There are two distinct groups at Seymour Johnson AFB that are involved in storm water pollution prevention planning. These groups include the Environmental, Safety and Occupational Health Council (ESOHC) and the Water Quality Working Group. These groups are discussed below. 2.2.1 Environmental, Safety and Occupational Health Council ESOHC is established by AFI 90-801 as the forum for engaging senior leadership in ESOH management. The ESOHC ensures a systematic, interdisciplinary approach to environment, safety and occupational health at each Air Force installation. The ESOHC meets quarterly and members include commanders, senior staff, and representatives from tenant organizations. The base Installation Management Flight (4 CES/CEI) briefs the status of the environmental programs to the ESOHC. 2.2.2 Water Quality Working Group The individual ultimately responsible for all activities at the base, including implementation of the SWP, is the Wing Commander. However, the SWP requires implementation of actions at all levels. The 4 CES/CEI Office is a member of the Water Quality Working Group (Cross Functional Team) who provides information to the base to support the SWPPT. The base Water Quality Manager (4 CES/ CEI) is the base representative and has the duties for implementing, reporting, and inspection of all aspects of the SWP. The Water Quality Working Group includes, at a minimum, the following squadron representatives: ➢ 4 CES/CEIE - Water Quality Program Manager ➢ 4 CES/CEIE - Natural Infrastructure Element Leader Storm Water Plan 2-1 Seymour Johnson AFB ➢ 4 CES/CEIE - Storage Tank Program Manager ➢ 4 CES/CEOH — Heavy Repair ➢ 4 CES/CENPM - Construction Management Inspectors ➢ 4 CONS/LGC - Contract Management Flight Representative ➢ 4 AMDS/SGGB - Bioenvironmental Flight Representative ➢ 4 OMRS — Operational Medical Readiness Squadron ➢ 4 EMS - Equipment Maintenance Squadron Representative ➢ 4 AMXS - Aircraft Maintenance Squadron Representative ➢ 4 FW/PA - Public Affairs ➢ 4 FW/JAC - Base Legal Office ➢ 4 LRS - Logistics Readiness Squadron Representative ➢ 4 CMS - Component Maintenance Squadron Representative ➢ 916 ARW - 916th Air Refueling Wing Representative Table 2-1 summarizes the minimum Water Quality Working Group/SWPPT information.

The most current list of unit environmental coordinators can be found on the base intranet EDASH website at: https:Hacc.eim.acc. of.mil/org/a7/A7A/edash/seMourj ohnson/Web%20Part%20Pages%20%20E nvironmental/Unit%20Environmental%20Coordinators%20(UECs). aspx. Unit Environmental Coordinators (UECs) maintain and improve environmental compliance and performance within their organizations, recognize and address problems when they occur, and act as points of contact for environmental issues concerning their organization (in accordance with Air Force Guidance). Key functional responsibilities including the management of hazardous materials and waste; air and water resources; spills management; natural and cultural resources; pollution prevention; toxic pollutants; and inspections. Training for UECs can be accomplished at the Air Force Institute of Technology (AFIT) via COURSE: WENV 220 Unit Environmental Coordinator (UEC). Storm Water Plan 2-3 Seymour Johnson AFB THIS PAGE INTENTIONALLY BLANK 2-4 3 PLAN MAINTENANCE 3.1 Plan Updates This Storm Water Plan provides a comprehensive review of the base industrial processes, storm water distribution system, and satisfies the requirements of NPDES Permit No. NCS000335 issued by the NCDEQ Division of Environmental Quality effective April 1, 2016. Data for the current SWP is collected during site visits, personnel interviews, telephone conversations, and correspondence conducted during the facility surveys and inspections. The plan includes the Annual Report, qualitative and quantitative monitoring data, Non -Storm and Illicit Discharge Survey, and updated tables with information describing the base compliance with the six minimum measure requirements. The SWP is intended to be a "living document" that is reviewed and updated as changes to facility operations and activities occur. The plan updates should reflect modifications in the management practices necessary to protect water quality. This plan will be reviewed, at a minimum, annually and revised as necessary by the 4 CES/CEI Water Quality Manager. During the qualitative monitoring periods, inspection of the industrial facilities, outfalls, BMP(s), and the base storm water distribution system is conducted by the Water Quality Manager, with assistance and inputs from the SWPPT. If monitoring and sampling are being performed, documentation of results shall be included. 3.2 Annual Storm Water Plan Review and Reports (NCS000332, Part III, (2) and Part I i) The base will submit a report of the evaluation and monitoring information to the state on an annual basis (beginning 1 April 2017). The annual report (see Appendix G) will include appropriate information to accurately describe the progress, status, and results of SJAFB SWP review and include, but are not limited to, the following information: ➢ Detailed description of the status of implementation of the SWP.

SJAFB has occupied its current location and conducted operations since April 1956. The 4th Fighter Wing, the base's host wing, is home to the multi - role, all-weather F-15E Strike Eagle and provides worldwide deployable aircraft and personnel capable of executing combat missions in support of the Aerospace Expeditionary Force. The 4th Fighter Wing provides logistical support to an Air Force Reserve wing, 916th Air Refueling Wing, which is a tenant wing responsible for maintaining and operating the KC-46A Pegasus tankers. Also the 567th Red Horse Squadron provides the Air Force with a highly mobile civil engineering capability in support of contingency and special operations worldwide. According to the Base Comprehensive Plan (Section 3.2.3 Population), the installation supports and serves a workforce population breakdown as follows: PERSONNEL Active Dufty Military 4,510 Reservists , 554 Tn�l Military ,054 t663 Appropriated Fund Civilians NAF - Appropriated Fund 61 DeCA - Appropriated Fund 58 T[t1a Civilian 782 Dependents 5,721 Retirees 10,178 A.*toersonnel..................22,73-5 The base Spill Prevention and Response Plan (Section 5.5) provides a description of the base storage practices. All fuel delivered via this pipeline is initially stored in five field -constructed ASTs, holding a total of 3.4 million gallons, located in the Petroleum, Oils, and Lubricants (POL) Bulk Storage Yard. From the bulk storage facility, fuel is distributed to six 50,000-gallon USTs at Pumphouse #2 via a 10-inch pipeline, and to two 420,000-gallon, field -constructed ASTs at the Type III Fuel Hydrant System via another 10-inch pipeline. From Type III Fuels Storage, fuel is piped to the KC-46 aircraft parking ramp fuel hydrants. The USTs at Pumphouse #2 are used to distribute fuel to the F-15 aircraft parking ramp fuel hydrants. In the future, all ramp hydrants will be supplied from the Type III ASTs, and Pumphouse #2 will be decommissioned. 4-1 4.2 Topography The main base occupies 3,233 acres (5.05 square miles) and is bounded on the north and northwest by Stoney Creek and on the west and southwest by the Neuse River. Figure 4-2, Seymour Johnson AFB Facility Map, (located on the base Geographical Information System (GIS)) provides an overview of the base facility layout including buildings, outfalls, parking areas, roads, runways, aprons, streams, deicing areas, vehicle and aircraft maintenance areas, storm water delineations, and oil water separators. A copy of the Existing Land Use Plan map from the SJAFB Installation Development Plan is shown in Figure 4-3. Seymour Johnson's topography includes the floodplain of the Neuse River. Elevations on base vary from approximately 45 to 110 feet, gradually sloping downward from the northeast to the southwest. The thickness of the surficial sediments beneath the base ranges from approximately 10 to 20 feet. Seymour Johnson AFB has a network of piped and open -channel storm water drainage systems that collect and transport rainfall runoff on the installation. The storm water drainage system consists of approximately 50 miles of drainage pipe which collects and empties storm water into nearby surface water bodies through a system of outfalls. Of the 50 miles of drainage pipe, 20 miles of pipe are associated with Military Family Housing (MFH). The main watercourses throughout the base consist of the Neuse River, Stoney Creek, Hospital Creek, Burge Ditch, Mayfield's Ditch (tributary to Stoney Creek and Burge Ditch), Prison Ditch (tributary to Stoney Creek), Golf Course Ditch and Golf Course Lake (tributary to Burge Ditch), and Bulk Fuels Ditch (tributary to Prison Ditch). 4.3 Groundwater Seymour Johnson AFB is located within the Piedmont physiographic province. The surficial unconfined aquifer is underlain by a series of interbedded sands and clays making up the regional, confined aquifer units of the Black Creek aquifer. At Seymour Johnson AFB the productive zones of the Black Creek aquifer are found below 10 feet mean sea level, which is approximately 90 feet below land surface at the base beneath the Black Creek aquifer, the Cape Fear Formation contains the third major aquifer system in the area. Depth to groundwater within the surficial aquifer ranges from approximately one foot below land surface near the Neuse River and its tributaries to about 15 feet below land surface in the central portion of Seymour Johnson AFB. The average hydraulic conductivity of the surficial aquifer in the vicinity of Seymour Johnson AFB has been reported to range from 5 to 40 ft/day. 4-2 13 Seymour Johnson AFB Raleigh 13 Seymour Johnson AFB Figure 4-1.

Flows from Stoney Creek and Burge Ditch ultimately discharges to the Neuse River. Stoney Creek is a small, winding stream that defines the northwestern and western boundaries of the base. Stoney Creek discharges to the Neuse River near the southwestern corner of the munitions storage area. The Neuse River, with headwaters near Danville, Virginia, drains a large watershed extending from the upper Pamlico Sound. This river forms the southwestern boundary of the base. Burge Ditch, located several hundred feet south of the flight line, begins near the eastern end of the runway. Burge Ditch begins as a grassy ditch and increases to a 10- to 12-foot wide stream with thick shrubs and herbaceous vegetation established on its banks. Burge Ditch receives water runoff from the Golf Course Lakes and from the 916th ramp area. As Burge Ditch nears the Neuse River, it widens to approximately 20 to 25 feet and its banks support riparian forest. Prison Ditch begins in a wooded area between the Red Horse Squadron and the Petroleum, Oils, and Lubricants (POL) Yard. It then flows through Red Horse Facility yards, under Peterson Avenue, and to its confluence with Stoney Creek. In the wooded area, the creek maintains a natural appearance. Hospital Creek is collects runoff from the areas around the hospital, Base Exchange (BX), Commissary, and Base Housing. Hospital Creek also receives runoff from a drainage ditch that flows from off base near Oak Forest Gate. 4-31 Mayfield's Ditch is located north of Building 2115, AGE Facility. The ditch continues underneath Propulsion Road and ultimately to Stoney Creek. The ditch collects runoff from AGE equipment and parking area. 4.9 Authorized Non -Storm Water Discharges (Part I (7)) The permit authorizes the point source discharge of storm water runoff from Seymour Johnson AFB. In addition, discharges of non -storm water are also authorized through the Seymour Johnson AFB if such discharges are: a. Permitted by, and in compliance with, another NPDES discharge permit including discharges of process and non -process wastewater, and storm water associated with industrial activity; or b. Determined to be incidental non -storm water flows that do not significantly impact water quality and may include: • Water line flushing; • Landscape irrigation; • Diverted stream flows; • Rising groundwater; • Uncontaminated groundwater infiltration; • Uncontaminated pumped groundwater; • Discharges from potable water sources; • Foundation drains; • Air conditioning condensate (commercial/residential); • Irrigation waters except reclaimed water as described in 15A NCAC 2H .0200; • Springs; • Water from crawl space pumps; • Footing drains; • Lawn watering; • Residential and charity car washing; • Flows from riparian habitats and wetlands; • Dechlorinated swimming pool discharges; • Street wash water; • Flows from emergency fire fighting; or • Releases of clean waters from hydrostatic testing. 4-32 4.10 Spill Prevention and Response Procedures Seymour Johnson AFB has prepared its SPCC plan per EPA's Oil Pollution Prevention regulation, 40 CFR 112. Under 40 CFR 112, facilities must detail and implement spill prevention and control measures in their SPCC Plans. The SPCC Plan, maintain by 4th CES/CEI, is to be used in preventing, to the maximum extent practical, the accidental release of oil discharges to the environment. In the event that a high risk spill does occur the SPCC Plan is written to assist spill response actions to minimize the potential impact to human health and the environment. The SPCC Plan enables the base personnel to: ➢ Become familiar with spill prevention and response procedures, including related regulatory requirements; ➢ Prevent injury to spill response personnel; Contact the SJAFB Fire Department; ➢ Appropriately respond to spills in a manner that will greatly reduce or eliminate contamination and prevent spill material from entering waters surrounding the base; ➢ Facilitate compliance with applicable regulatory requirements; and ➢ Maintain a safe installation working environment. If a spill occurs, the primary goal after the safety of personnel has been ensured is environmental protection by containing the spill material as close to the source as possible. Spill containment may be accomplished as individual events dictate with any one or combination of the following: ➢ Use of portable spill containment equipment such as booms and oil absorbent material; ➢ Blocking the flow at a storm water inlet; or ➢ Constructing an earthen dam/berm in the path of or around a spill. Spill prevention and response BMPs include the following: ➢ Spill kits; ➢ Spill response and reporting (SPCC Plan, Appendix B.4.1, Initial Shop Spill Report); ➢ Containment diking and release inspections (SPCC Plan, Appendix C.2, Release Form); ➢ Cathodic protection; ➢ AST Monthly Inspection Forms (SPCC Plan, Appendix C.1); ➢ Overflow protection devices; 4-33 ➢ Refueling, overflows; ➢ Refueling, topping -off tanks during refueling; ➢ Security, locked funnels; ➢ Security, locked containment discharge drains; and ➢ Security, traffic guards. North Carolina General Statues 143-215.94 (A) requires reporting to the department 24- hour emergency response number, Washington Regional Office (252) (946-6481 if: a. Hazardous Substances are spilled in excess of the reportable quantity b. If petroleum products released or spilled is 25 gallons or more c. If petroleum products causes a sheen on nearby state surface waters d. If spill or release is 100 feet or less from state surface water bodies Trained spilled response personnel must immediately take measures to collect and remove the discharge. The Civil Engineer Squadron Installation Management Flight is responsible to report the discharge to regulatory agencies. A report to NCDEQ must be made within 24 hours and begin to restore area affected by discharge. If a petroleum discharge is less than 25 gallons and cannot be cleaned up within 24 hours of the discharge, or if the discharge causes sheen on nearby state surface waters, the SJAFB shall immediately notify the department. 4.11 Sanitary Sewer Overflows Compliance Guidance Sanitary Sewer Overflows (SSOs) are discharges of untreated wastewater to the base storm water drainage system. SSOs are unsightly and a public health issue. Problems that can cause SSOs include: • Infiltration/Inflow (I&1): too much rainfall infiltrating through the ground into sanitary sewers not designed to hold storm water; leaking manholes; and excess water inflowing through illegal connections such as roof drains. Pipe Failures: blocked, broken or cracked pipes which can be caused by tree roots growing into the sewer lines; fats, oils and grease being poured down drains; and settlement/shifting of ground or pipe. • Deteriorating Sewer System: older infrastructure systems can be expensive to repair over time; or system capacity may need to be increased. 4-34 Seymour Johnson AFB has an aggressive Infiltration and Inflow (I&I) program to significantly reduce and/or eliminate SSOs. Replacing and rehabilitating sanitary lines and manholes reduces I&I into the sanitary sewer system, thereby protecting the public health, improving treatment plant efficiency and reducing system maintenance. Base personnel who observe a sanitary sewer overflow shall report these as emergencies to the 4th Civil Engineering Squadron Customer Service at 722-5126 and the Water Quality Manager at 722-5168. Because SSOs can carry bacteria and viruses, do not approach an overflow. Verbal reports will be made to DWQ no more than 24 hours following knowledge of • Any SSO and/or spill over 1,000 gallons to the ground or; • Any SSO and/or spill, regardless of volume, that reaches surface waters. SSOs (and other types of spills) occurring outside normal business hours may also be reported to the Division of Emergency Management at telephone number (800) 858-0368 or (919) 733- 3300. State Emergency Notifications and Release Forms: Form and Content for Press Release - Required for a discharge of 1,000 gallons or more of untreated wastewater to surface waters of the State (see Memo/General Statute for detailed distribution requirements) Form and Content for Public Notice - Required for a discharge of 15,000 gallons or more of untreated wastewater to surface waters of the State (see Memo/General Statute for detailed distribution requirements) SSO Reporting Form (CS-SSO Form) - 5-Day Report (Word Version) 4.12 Erosion and Sedimentation Control Guidance Personnel at Seymour Johnson AFB should report evidence of prohibited amounts of sediment or any illicit discharges (foam, unknown substances, etc.) into the base streams to the Water Quality Manager at 4 CES/CEI, 722-5168. In addition, the state has set up a toll free hotline for citizens to report possible violations of erosion control measures at 1-866-STOPMUD (786-7683) -- Sedimentation Pollution Control Act. 4.13 Spill Response and Storm Water Training Seymour Johnson AFB personnel involved in spill response will have the required training as specified in AFI 32-4002. Spill prevention awareness training is provided annually to base personnel through the base website "TEACH" and page identified as "Spill Prevention, and Countermeasures". A copy of the front of the webpage is shown below in Figure 4-4. In addition, the Defense Logistics Agency Energy contractor trains and conducts annual spill response equipment deployment exercises for fuels Airmen as well as other base agencies in accordance with the Oil Pollution Act of 1990. 4-3 5 Figure 4-4. TEACH AWARENESS Webpage r rE—" course eomaieuon Loq m........- .., Teach Link: htt2s://usaf.leaminybuilder.com/account/login/?RetumUrl=%2fLEARER%2fLEARNINUpLAN%2fVIEW Specific training requirements are mandated by Federal regulations, including 29 CFR 1910 and National Fire Protection Association standards. All personnel assigned to the Hazardous Materials (HAZMAT) Response Team, including the Fire Department, will receive HAZMAT training. Other response organizations will receive training in the area of their response responsibility, such as emergency medical technician training. To prevent expiration of training requirements, yearly refresher courses are provided for personnel, when applicable. Individual training records, such as AF Form 55, Employee Safety and Health Record, or other approved documentation is used to record participation in training courses. An annual employee -training web -based course entitled "Storm Water - Basic Information" and a "Storm Water - Comprehensive Overview" are provided to personnel and contractors who may come into contact with pollutants that may be discharged to storm water. The courses are designed to educate personnel on the practices that are required to minimize on -site pollution of storm water. At a minimum, all personnel (military and civilian) need: • Environmental Management System (EMS) General Awareness Training(per AFI 32- 7001, Section 5.7), via ADLS(ZZ133070)or TEACH(Course Number EMS 100AFIT00004) • Storm Water Management-Awareness(per the SJAFB Stormwater permit issued by the State of North Carolina), via TEACH(Course Number SWM100AFIT00026) • All personnel handliniz liauid petroleum products or used cookine oil/crease and personnel who oversee or administer government contracts involving liquid petroleum products should complete: Petroleum, Oils and Lubricants (POL) Management - Awareness(per the SJAFB Spill Prevention Control, and Countermeasures Plan, Section 4.1.1; also known as SPCC training), via TEACH(Course Number POL100AFIT000 • The SPCC Plan can be viewed using the followin lg ink: https://cs2.eis.af.mil/sites/1 0623/Seymou r/Shared %20Documents/Envi ron me ntal%20Docurnents/Fuel POL Tanks/SPCC-SJAFB-2016.pdf 4-36 (Note: The Microsoft Edge web browser will not open many .mil sites; use Internet Explorer instead) The 4 CES/CEI also conducts briefings and distribute emails to contract managers and conducts training on Storm Water Management at Construction Sites periodically. The target audience typically consists of environmental managers, construction engineers, and construction supervisors. Subjects include topics on erosion and sedimentation control, monitoring and sampling, BMPs, site inspections, oil water separator management, grease management, spill prevention, and record keeping. Specific Storm Water Training classes and documents are also available and can be found on the CEI Environmental Website "EDASH". 4.14 Unit Environmental Coordinator Training The Unit Environmental Coordinator (UEC) represents their respective squadron in all environmental matters. They conduct facility assessments of each work center, assist and identify industrial processes and discharges at their faculties, ensure environmental findings are acted upon and corrected, ensure environmental training requirements within their respective squadron are identified to 4 CES/CEI, and report status of MICTI findings to their respective squadron commanders and/or group commanders. In accordance with Executive Order 13423, Strengthening Federal Environmental, Energy, and Transportation Management, SJAFB developed an ISO 14001 based EMS. EMS is a set of processes and practices that enable an organization to reduce its environmental impacts and increase its operating efficiency. EMS is built on the "Plan, Do, Check, Act" model. Plan by identifying environmental aspects and establishing goals; Do require training and operational controls; and Check includes monitoring and corrective actions; Act involves conducting a self -evaluation of the effectiveness of the EMS in achieving desired levels of environmental performance. 4-37 THIS PAGE INTENTIONALLY BLANK 4-3 8 5 PUBLIC EDUCATION AND OUTREACH (NCS000335, Section B) 5.1 Objective for Public Education and Outreach - see APPENDIX H "Six Minimum Measures and Status/Public Education and Outreach Section" for distributed materials and filled in BMP tables.

Reduce pollutants in storm water runoff from construction 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. b. Provide 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. c. Establish 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. Sedimentation and Erosion control practices at construction site will primarily be managed through base contracts, the work order review process, digging permits, and statement of works. Contractors are required to abide by the requirements of their state approved erosion and sedimentation control plans. The base contracting officer and the base qualified assurance inspector have the ability to cease all work on base. The base must also complete storm water Self -Inspection Program. The self inspection program is separate from the weekly self -monitoring program of the NPDES Storm Water Permit for Construction Activities. The focus of the program is on installation and maintenance of erosion and sedimentation control measures according to the approved plan. Inspections are required and should be conducted after each phase of the project and continued until permanent ground cover is established. Copy of the state self -inspection form can be found in Appendix H. 8.2 Seymour Johnson AFB Relies on the NCDENR Division of Land Resources The NCDENR Division of Energy, Mineral, and Land Resources (DEMLR) Erosion Sediment Control Program effectively meets the requirements of the Construction Site Runoff Controls by permitting (NCGO1) 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. DEMLR 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. A copy of the General Construction Permit NCGOIcan be found in Appendix D. Discharges that do require NPDES Permits: §122.3 CWA Exclusions. The following discharges do not require NPDES permits: (e) Any introduction of pollutants from nonpoint-source agricultural and silvicultural activities, including storm water runoff from orchards, cultivated crops, pastures, range lands, and forest Storm Water Plan 8-1 Seymour Johnson AFB lands, but not discharges from concentrated animal feeding operations as defined in § 122.23, discharges from concentrated aquatic animal production facilities as defined in § 122.24, discharges to aquaculture projects as defined in § 122.25, and discharges from silvicultural point sources as defined in § 122.27. NCGO10000 shall not apply to land -disturbing activities that are covered under the NCG020000 (Mining Activities) permit or the NCG120000 (Landfills) permit. • The NCGO1 permit provides protection for projects that are subject to both the Clean Water Act and the SPCA. • The NCG25 protects the relatively few projects that are subject to the Clean Water Act but not the SPCA. Point source means any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharged.

NPDES Permit NCS000335 requires SJAFB to develop, implement, and enforce a program to address storm water runoff from new development and redevelopment projects, including public transportation maintained by Seymour Johnson AFB. b. Develop and implement strategies which include a combination of structural and/or non-structural best management practices (BMPs) appropriate for the base; and c. Ensure adequate long-term operation and maintenance of BMPs. d. Comprehensive Watershed Protection Plans. SJAFB has developed and implemented a comprehensive watershed protection plan, approved by the State, to meet part or all of the requirements for a post -construction program. 9.2 Post -Construction Site Runoff Controls To meet all of the objectives of the Post -Construction Site Runoff Controls, SJAFB has decided to implement a Comprehensive Watershed Protection Plan which includes future planning requirements in the Seymour Johnson Base Master Plan (15A NCAC 0211.1017 (13). This report assists SJAFB with meeting Section F (2b), NPDES NCS000335, Post -Construction Site Runoff Control requirements, in providing a strategy to implement a comprehensive watershed protection program. All projects, including public roads and bridges 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 that are performed by, or under contract for, Seymour Johnson AFB, including roads and bridges must meet the requirements of the stormwater management and water quality protection required by Session Law 2006-246 and 15A NCAC 2H .1000 rules (hereafter referred to as the "stormwater rules'). Roads and bridges must minimize built -upon surfaces, divert stormwater away from surface waters as much as possible and employ other best management practices to minimize water quality impacts to the maximum extent practicable. The base NPDES NCS000335 Permit has no requirements to meet EISA 438; however, all DoD construction projects with a building footprint greater than 5,000 square feet or expand the footprint by more than 5,000 square feet must comply with EISA 438. Management is only for the additional impervious area added. NC DEO on October 11, 2015 approved Seymour Johnson AFB Comprehensive Watershed Protection Plan. NC DEQ requires that in the future, all Storm Water Annual Reports, for each demolition project and/or added projects (development or redevelopment) that added impervious areas, other than routine maintenance and improvement projects, that are greater than 5,000 s.£, will be determined and reporting using details Storm Water Plan 9-1 Seymour Johnson AFB mentioned in Table 9-1. Required for projects that create and/or replace 5, 000 square feet or greater of impervious surface (i.e. asphalt roads, concrete structures, building area, sidewalks, etc). Impervious surfaces are those that water cannot infiltrate/soak into. SESSION LAW 2014-90 HOUSE BILL 201: PART IL STORMWATER PROGRAM IMPERVIOUS SURFACE CALCULATIONS FOR REDEVELOPMENT. (a) Definitions. — The following definitions apply in this law: (1) Development. — Any land -disturbing activity that increases the amount of built -upon area or that otherwise decreases the infiltration of precipitation into the subsoil. (2) Redevelopment. — Any land -disturbing activity that does not result in a net increase in built -upon area and that provides greater or equal stormwater control to that of the previous development. Session Law 2014-120, which was signed into law on September 18, 2014, further amended the definition of "built -upon area" in G.S. 143- 214.7 such that "gravel" is no longer excluded from being considered "built -upon area." Session Law 2014-120 also prohibited the EMC from defining the term "gravel" in the context of its stormwater programs. However, the proposed rule will not require local governments who administer stormwater programs to deviate from current practices; as such, there will be neither a direct cost nor opportunity cost for local governments as a result of the proposed rule change. Local governments may, at their discretion, choose to revise their local ordinances to match the State's definitions of "built -upon area" and "gravel," but they would not be required to do so as long as their ordinances continue to be at least as stringent as the State's rules. SESSION LAW 2012-200 SENATE BILL 229, directs the Department shall not require the use of stormwater retention ponds, stormwater detention ponds, or any other stormwater control measure that promotes standing water in order to comply with this section at public airports that support commercial air carriers or general aviation services. Development projects located within five statute miles from the farthest edge of an airport air operations area, as that term is defined in 14 C.F.R. § 153.3 (July 2011 Edition), shall not be required to use stormwater retention ponds, stormwater detention ponds, or any other stormwater control measure that promotes standing water in order to comply with this section. SESSION LAW 2006-246 SENATE BILL 1566 (2) Permittees and regulated entities must implement or require an operation and maintenance plan that ensures the adequate long-term operation of the structural BMPs. The O&M plan must require the owner of each structural BMP to submit a maintenance inspection report on each structural BMP annually to the local program. 15A NCAC 02H .1017 - FECAL COLIFORM REDUCTION. Regulated entities and delegated programs shall implement a fecal coliform reduction program that controls, to the maximum extent practicable, sources of fecal coliform. At a minimum, the program shall include a pet waste management component, which may be achieved by revising an existing litter ordinance, and an on -site domestic wastewater treatment system component to ensure proper operation and maintenance of such systems, which may be O coordinated with local county health departments. Corvias (MFH Privatized Area) has a Resident Responsibility Guide that details procedures for maintaining pets and pet waste. All maintenance areas must be free of pet waste. http://airforce.corviasmilita . lr�g.com/sites/default/files/document_center/Continental%20Group%20RRG%20FINAL.pdfI SJAFB has three dog parks with pet stations and rules posted on how to handle pet waste.

Seymour Johnson AFB will submit reporting and monitoring information on an annual (by 31 March of the following year) basis per Part III of the NPDES Permit on forms provided by the DWQ. Storm Water Plan 13-1 Seymour Johnson AFB Cutoff Concentrations. For each parameter, the arithmetic mean of all analytical sampling results collected during the term of the permit shall be calculated for each individual outfall and compared to the cut-off concentrations listed below. At a minimum, Seymour Johnson AFB must perform analytical sampling during the first year of the permit. If the analytical results fall at or below the cutoff concentrations listed below, Seymour Johnson AFB is not required to sample that parameter at that outfall for the remainder of the permit. If analytical results exceed the cutoff concentration, subsequent sampling is required annually. Each year, Seymour Johnson AFB has the option to assess if the arithmetic mean of data collected for each parameter at each outfall is below the cutoff concentration. If the arithmetic mean is less than the cutoff concentration then Seymour Johnson AFB is not required to continue analytical monitoring for that parameter at that outfall during the remainder of the term of the permit unless a significant change in the operations in the drainage area occurs. In FY2016 SJAFB has submitted and met all requirements for meeting cutoff concentrations and will not have to complete quantitative sampling at outfalls for the remainder of the permit period. Cutoff Concentration Table 13.3 Parameter Cut-off Concentration Oil and Grease 30 mg/l pH (do not take average, use most recent pH sample result) 6-9 standard units TSS 100 mg/l When required herein, stormwater samples collected and measurements taken shall be characteristic of the volume and nature of the permitted discharge. Analytical stormwater sampling shall be performed during a representative storm event. These samples shall be taken on a day and time that is characteristic of the discharge. Where appropriate, all stormwater samples shall be taken before the discharge joins or is diluted by any other waste stream, body of water, or substance. When specified herein, monitoring points established in this permit shall not be changed without notification to and approval of the Director. Seymour Johnson AFB shall retain all monitoring information for a period of at least 5 years from the date of the sample, measurement, report or application. This period may be extended by request of the Director at any time. When no discharge has occurred from the facility during the report period, Seymour Johnson AFB indicate "NO FLOW" as per NCAC T15A 02B .0506. 13.2 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 and/or oil water separator discharging to storm regardless of representative outfall status. No 13-2 analytical tests are required. Qualitative monitoring of storm water outfalls does not need to be performed during a representative storm event. All qualitative monitoring will be performed twice per year, once during the spring (April -June) and once in the fall (September -November). If the permittee's qualitative monitoring indicates that existing storm water BMPs are ineffective, or that significant storm water contamination is present, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement those corrective actions appropriate. A written record of the permittee's investigation, evaluation, and response actions shall be kept in the SWP. Seymour Johnson AFB shall record the required qualitative monitoring observations on the SDO Qualitative Monitoring Report form provided by the Division, and shall retain the completed forms on site.

One grab sample is collected from each outfall (Outfall 2, 3, and 4) during a representative storm event. Quantitative NPDES reporting forms can be found in Appendix F. Definitions of Grab sample and representative storm event as defined in the NPDES permit are as follows: • Grab sample - An individual sample collected instantaneously. Grab samples that will be directly analyzed or qualitatively monitored must be taken within the first 30 minutes of discharge. • Representative storm event (Part VIII Page 4 of 7) - A storm event that measures greater than 0.1 inches of rainfall. The time between this storm event and the previous storm event measuring greater than 0.1 inches must be at least 72 hours. Therefore as long as you do not have a rain event greater than 0.1 inches in 72 hours, you can sample. A single storm event may contain up to 10 consecutive hours of no precipitation. For example, if it rains for 2 hours without producing any collectable discharge, and then stops, a sample may be collected if a rain producing a discharge begins again within the next 10 hours. Prior to sampling, the storm water contractor verifies and ensures rainfall amount 0.1 inch with an onsite rain gauge that the storm event is representative. Bottles received from the lab are labeled according to site number, sample type, and preservatives. Take cooler with ice and samples to the site (samples should be 0.4 degrees). Contractor will manually collect grab samples from each of the base representative outfalls by inserting a container under or down current of a discharge with the container opening facing upstream. Sample sites should be free flowing (avoid still water sampling) and not affected by backwater and/or tidal conditions. Use pole or buckets for less accessible outfalls. Care must be used to avoid touching the inside of the container, stirring up bottom sediment in the open channels, and keeping the sample free from uncharacteristic floating debris. Sample where the water has moderate flow. Sampling in still water should be avoided. Take sample from the central portion of the storm water flow while avoiding touching the bottom of stream. Do not rinse or overfill the bottle. Always wear protective equipment (gloves and glasses). Notify someone before you go out to complete sampling. Sample data (TSS, Oils and Grease, and pH) are collected from the outfalls using long -handled dippers and sample aliquots supplied by the lab and are delivered directly into labeled sample containers. TSS bench mark is 100 mg/L. When sampling for Oils and Grease (O&G, bench mark 30 mg/L), use sample bottles supplied by the lab. O&G will adhere to containers and thus should not be transferred from one container to another. Create head space in sample bottles for mixing (do not overfill bottles with preservatives). Sample containers are taken at the site and placed in plastic bags before introducing them to a cooler completely surrounded by ice. Samples must be labeled to prevent misidentification of samples. Field notes (Rite -in Rain) should be completed before leaving the sites (weather, conditions of outfall, etc). Storm Water Plan 15-1 Seymour Johnson AFB Note should say location/site #, name of collector, date and time (to ensure holding times are met), analysis requested, and preservative. pH is the only parameter that must be measured in the field. Also include pH calibration information for meter, ambient field conditions, how many bottles for each sample, temperature of water in field notes. Temperature at lab is normally checked to see if it is stored at 4 degrees C. Under no condition shall a thermometer be placed into the container. Temperature readings are taking in the outfall discharge. Bottom of cooler should have absorbent pad and large plastic bag to hold containers and ice. Fill two 3-gallon bags with ice and one 1-gallon bag with ice. Place one 3-gallon bag on bottom of cooler and one 1-gallon bag on side of containers. Place second 3-gallon bag on top of containers and seal plastic bag. Tape chain of custody form to inside lid of cooler. Samples are mailed (FEDEX) to a NC contracted laboratory (e.g., SGS North America Inc, Wilmington, North Carolina) under standard chain -of -custody procedures. Samples analyzed in accordance with the terms of the permit shall be submitted to the Division on Discharge Monitoring Forms provided by the Director. Submittals shall be delivered to the Division no later than 30 days from the date SJAFB receives the sampling results from the lab. In addition, SJAFB will submit a report of this evaluation and monitoring information to the Division on an annual basis (31 March). When no discharge has occurred from the facility during the report period, SJAFB is required to submit a discharge monitoring report and indicating "NO FLOW" as per NCAC TI5A02B.0506. Never conduct storm water sampling during unsafe conditions (thunder storms, lightning, etc). Storm water sample containers should be cleaned and prepared for field use (or supplied by the lab) according to the procedures set forth in 40 CFR Part 136. However do not decontaminate sample bottles prior to sample collection. A summary of the procedures is presented below for plastic containers: • Nonphosphate detergent and tap water wash • Tap water rinse • 10 percent nitric acid rinse (only if sample is to be analyzed for metals) • Distilled/deionized water rinse • Total air dry The contractor will use the HI 9126 Ph/ORP Meter (or similar) to collect the pH and temperature samples. Calibrate the meter using the HANNA Instrument Solutions pH 4.01 (HI70004), pH 7.01 (HI 70007), and Cleaning Solution for Agriculture Application (HI700661). Place the temperature probe and the pH meter probe into the deionized water. Turn on the 15-2 meter and let the LCD completed load into measurement mode. Push the Cal button and move into the calibration mode. The meter will ask for 7.01 buffer. Put the temperature probe and meter probe into 7.01 package. Meter should calibrate to near or at 7.01 and then push the confirm button (bottom left hand corner). Meter then will ask for the 4.01 button. Now take the probes and rinse in deionized water and then place in 4.01 buffer. Wait for confirmation. Hit confirm button and meter will move into measurement mode and you are ready to begin taking pH meter readings. 15.2 Runoff Volume Calculation As required by the NPDES permit, total runoff volume (flow) is also calculated. The runoff calculation for each drainage basin is based on the amount of area draining to the sampling outfall, the amount of impervious and pervious area, and the total amount of rainfall. Sampling site Outfall 02 receives runoff from drainage area 09, 10, 1 lb, and 1 lc. Sampling site Outfall 03 receives runoff from drainage areas 03a, 03b, 03c, and 03d. Sampling site Outfall 04 receives runoff from drainage area 04 only. The total flow to a particular sampling outfall must include the flow from each drainage area that discharges the respective sampling outfall. The flow equation that Seymour Johnson uses to determine runoff volumes is presented below. Vt = Rt X [(Apaved X C..ff) + (Apaved X Crwoff)l Where: Vt = the total runoff volume (ft) Rt = the total rainfall (ft) Apaved = the area within the drainage basin that is paved or roofed (ft) Aupaved = the area within the drainage basin that is unpaved (ft) C.off = a specific runoff coefficient for the drainage area ground cover (unitless) VT = Sum of Vt for each sampling outfall (ft3) Assume: C.off for paved area is 0.90 Crumff for unpaved area is 0.50 The flow calculation can be determined using a spreadsheet once rainfall data is available. A typical spreadsheet set up for this calculation is presented in Table 15-1. Storm Water Plan 15-3 Seymour Johnson AFB Table 15-1.

Qualitative Storm Water Monitoring Locations, Seymour Johnson AFB 15-5 15.3 Qualitative Requirements In accordance with NPDES NCS000335 Section J, 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 industrial storm water outfall associated with industrial activities and/or oil water separators regardless of representative outfall status. Qualitative monitoring of storm water outfalls does not need to be performed during a representative storm event. All qualitative monitoring will be performed twice per year, once during the spring (April -June) and once in the fall (September -November). If the permittee's qualitative monitoring indicates that existing storm water BMPs are ineffective, or that significant storm water contamination is present, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement those corrective actions appropriate. A written record of the permittee's investigation, evaluation, and response actions shall be kept in the SWP. Copies of the qualitative monitoring forms can be found in Appendix E. The 4 CES/CEI Water Quality Manager also maintains a Storm Water Sampling Plan which contains storm water sampling procedures, the state Qualitative Monitoring Report Supplement (SWU-242A), Qualitative Monitoring Report Forms, and pH Calibration Instructions.
