Program Summary and Assessment Fort Bragg is authorized to discharge stormwater and continue operation of oil water separators not associated with wastewater facilities under North Carolina Department of Environment Quality (NCDEQ), Division of Energy, Mineral and Land Resources Quality, Permit Number NCS000331 (initial effective 1 April 2011 — 31 March 2016, renewal effective 1 April 2016 — 31 March 2021, amended 6, July 2016), hereinafter "the Permit." In accordance with Part III and Part 1V of the permit, Fort Bragg hereby submits this report in fulfillment of its annual reporting requirement. Fort Bragg believes the single best indicator of how the Stormwater Management Program is performing is by monitoring the amount of pollution entering the stormwater. The results of this Year's sampling analysis did not detect frequencies of exceedance of water quality standards. Additionally, no detectable trends in concentrations of constituents occurred upon review of the historical stormwater sampling data. This annual report provides the updated status of the Installations implementation of the Permit requirements, including compliance with the standard of reducing the discharge of pollutants to the Maximum Extent Practicable (MEP). ll. Minimum Control Measures Discussions A. Public Education and Outreach According to Part 11, Section B of the Phase II permit, the objectives of the Public Education and Outreach measure is to distribute educational materials to the community or conduct equivalent outreach activities about the impacts of stormwater discharges on water bodies and the steps that the public can take to reduce pollutants in stormwater runoff.

The following activities were completed for this Year's reporting period. • Fort Bragg Continued "Adopt a Lake" activity for McFayden Pond by having an individual military unit commit to revisit the lake annually to perform cleanup around the lake and adjacent park. • Fort Bragg continued "Operation Clean Sweep" initiatives across the installation. All units on Fort Bragg (over 50,000 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. • Earth Day April 22, 2018- Fort Bragg's social media campaign for Earth Day asked the community, What can you do to be sustainable? Sustainability is a team effort seeded in integrity. Whether it is conserving energy and water, not littering and picking up trash, or recycling, it is The Right Ways The Green Way! Ali the Way! 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 maps and 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. Fort Bragg conducts dry weather flow inspections of stormwater outfalls. For this reporting year, a total of 210 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 2017 through 31 March 2018, there were 10 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.
