The following Public Education and Outreach activities were completed during this Year's reporting period; • Fort Bragg Environmental Division Water Management Section partnered with PWC and the Junior League of Fayetteville to educate 500 Fort Bragg students at Westarea Elementary School Career Day May 3, 2019. Students received; coloring books, backpacks, and a hands-on Stormwater Pollution demonstration. Instruction was provided on "Only Rain in the Storm Drain", importance of keeping waterways clean, and what pollution prevention can be accomplish through recycling. • Fort Bragg has completed its sixteenth year of its stormwater inlet labeling campaign "Only Rain in the Storm Drain". To date well over seven thousand storm drain markers have been installed or replaced as a component of Fort Bragg's continuing efforts to educate soldiers and their families to better understand the consequences of allowing pollutants to enter our storm drain system. The initial 20 hour and 8 hour refresher Environmental Compliance Officer/Environmental Compliance Assistant training continued each month with a total of 902 students trained. Additional, training and outreach occurred throughout the year at the unit level during the Compliance Assessment Team (CAT) inspections of industrial areas. • WMS continued sediment/erosion control and stormwater controls training on an ad hoc basis during numerous construction site inspections. This training includes project design, NCDEQ requirements, and control measures installation and maintenance. B. Public Involvement and Participation According to Part 11, Section C of the Phase 11 permit, the objectives of the Public Involvement and Participation measure is to comply with State and local public notice requirements when implementing a public involvement and participation program. The target audience for this measure has been identified as the Installation population and local volunteers that can be involved in stream/lake cleanup or storm drain stenciling activities. The following activities were completed for this Year's reporting period. • Sustainable Fort Bragg "Green Boot program" continues to enhance our environment through resource stewardship. The goal is to reduce environmenta impacts through initiatives such as water conservation, pollution prevention and recycling to name a few initiatives promoted within the installation. Fort Bragg continued "Operation Clean Sweep" initiatives across the installation. All units on Fort Bragg (over 70,000 Soldiers) participate in the week long installation wide clean-up program. The soldiers police -up trash and sweep common areas to include around barracks, offices, parking lots, recreational areas, and roads. C. Illicit Discharge Detection and Elimination According to Part II, Section D of the Phase II permit, the objective of the Illicit Discharge Detection and Elimination measure is to develop, implement, and enforce a program to detect and eliminate illicit discharges into the State's waters. The following activities were completed or were ongoing within this Year's reporting period; Fort Bragg's GIS contains information depicting the stormwater MS4 system information including pipe material shapes and sizes, drainage structures, outfalls, detention/retention basins, and monitoring locations. Data is updated continuously on a regular basis. Approximately 10,000 edits/updates were made to the Stormwater MS4 system layers. Fort Bragg conducts dry weather flow inspections of stormwater outfalls. For this reporting year, a total of 272 outfalls were inspected at Fort Bragg, Pope and Simmons Army Airfields, and Camp Mackall. No illicit discharges were detected. All Illicit discharges/spills, including sewage, are reported to the Fort Bragg Fire Department/Spill Response Team and/or DPW Environmental Compliance Branch. These reports are then forwarded to NCDENR. Copies of spill reports are maintained in the DPW Environmental Compliance Branch. From 1 April 2019 through 31 March 2020, there were 3 reportable hazardous substance spills (fuel, oil, gasoline) that reached the Fort Bragg storm drain system. • Procedures for sanitary sewer overflows are investigated and cleaned up by Old North Utilities Service (ONUS) and reported to the contracting officer representative, Stormwater Manager, and NCDNER as necessary.

These inspections and maintenance procedures ensure long term operation and a sustainable return on investment. F. Pollution Prevention/Good Housekeeping for Municipal Operations According to Part II, Section G, of the Phase If permit, the objective of the Pollution Prevention measure is to implement a program that has a training component and has the ultimate goal of preventing or reducing pollutant runoff. The majority of industrial activities on Fort Bragg are located in the cantonment area. ECO's and ECA's are trained in areas of good housekeeping, materials management, spill control, stormwater management, and wash rack/oil water separator management. Compliance in these areas is determined by formal inspections performed by the Compliance Assessment Team. Operation and Maintenance Division Road Section sweeps leaves and debris from streets/roads, airfields, and parking lots. The following activities were completed within this Year's reporting period; • The Compliance Assessment Team conducted over 1,852 Inspections of all military units, directorates and contractors that produce hazardous waste (HW) or Universal Waste (UW) to ensure compliance with applicable Federal, State and DoD environmental regulations. • Water Management Section continuously updates GIS Outfall, sampling locations, and stormwater control measures maps. • Continued use of OWS systems to capture oil and grease from vehicle and equipment cleaning. Fort Bragg has an O&M Plan for oil/water separators. ECOs and ECAs inspect their industrial areas once each month. • Fort Bragg continues street sweeping activities to remove leaves and debris from streets/roads, airfields, and parking lots. A total of 9,247 miles were swept during this reporting period. • Continued to ensure that Fort Bragg personnel are properly trained for pesticide, herbicide, and fertilizer application according to DOD instruction 4150.07. • Continued the 20-hr ECO/ECA Training Class providing information on pollution prevention, spill prevention/response procedures, and good housekeeping practices. The Compliance Assessment Team trained 1,180 students in the ECOIECA course. • In addition to the SWMP required activities, Fort Bragg also conducted ongoing activities including collection of refuse, recycling, HHW, electronics, green waste, and a green building program. These programs all contribute to the goal of reducing or eliminating the potential pollutants impacting stormwater. • Fort Braggs Grease Interceptor Consolidation and Management Plan and the Grease Control Plan minimize discharge of fats, oils and grease into the sanitary sewer collection system to reduce overflows. • Stormwater outfall maintenance was conducted in the spring & fall prior to the accomplishment of the permit required semiannual qualitative monitoring on 91 outfalls. Periodic vegetation, sediment and trash removal maintenance is required in order to safely access these sites for regulatory monitoring purposes. G. Monitoring & Evaluation As required by Part ll, Section J of Permit No. NCS000331, 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 fisted below. At a minimum, Fort Bragg must perform analytical sampling during the first year of the permit. If the analytical results fall at or below the cutoff concentrations listed below, Fort Bragg 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, Fort Bragg 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 Fort Bragg 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. Fort Bragg has elected to use the option of arithmetic mean. Table 1 provided below summarizes the sampling Arithmetic Mean results.
