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 target audiences have been identified as construction contractors and inspectors, housing residents, environmental compliance officers, and range operation personnel. The following Public Education and Outreach activities were completed during this year's reporting period: • 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 (ECO)/Environmental Compliance Assistant (ECA) training continued each month with 902 students trained. Additionally, 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 stormwater 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 • Procedures for sanitary sewer overflows are investigated and cleaned up by American States Utilities Service (ASUS, formerly Old North Utilitiets Service (ONUS)) and reported to the contracting officer representative, Stormwater Manager, and NCDNER as necessary.

Construction Site Stormwater Runoff Control According to Part II, Section E of the Phase II permit, Fort Bragg's compliance with the NCDENR Division of Energy, Mineral and Land Resources Erosion and Sediment Control Program effectively meets the requirements of the Construction Site Runoff Controls. The following activities were completed within this year's reporting period: Construction Site Runoff Control Program Assessment QTY Active NCDEQ Land Disturbing Permits 43 Completed/Closed Out NCDEQ Land Disturbing 21 Permits Water Management Land Disturbing Project 81 Approvals Water Management/Environmental Clearances 139 Project Reviews Projects Receiving NOVs 1 NCDEQ Erosion &Sediment Control 137 Inspections Water Management Erosion &Sediment 67 Control Inspections E. Post-Construction Site Runoff Controls According to Part II, Section F, 2 of the Phase II permit, to comply with the Post Construction requirements in 15 NCAC 02H Section .1000, Fort Bragg shall submit, for approval, plans, supplement forms, specifications, and calculations to the Division for 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. Fort Bragg may reference their approved base wide SCM O&M Plan to meet a project's O&M requirements. Additionally, to protect water quality in North Carolina rivers, streams, and lakes, and the existing uses of such surface waters for their scenery, swimming, boating, as well as for commercial and recreational fishing Fort Bragg shall maintain an inventory and all plans and documents for Stormwater Control Measures approved by the State after July 1, 2007. Fort Bragg shall inspect and maintain all Stormwater Control Measures approved by the State after July 1, 2007 in accordance with the schedule developed by Fort Bragg The following activities were completed this reporting period: Post-Construction Site Runoff Controls Program Assessment QTY Stormwater plans reviewed/submitted for 41 State a p p r o v a l Reviews 6 submitted Stormwater Control Measures approved by the 255 State after July 1, 2007 total inventory Stormwater Control Measures total inventory on 821 Ft Bragg Stormwater Control Measures added 17 Stormwater Control Measures inspections. 575 Stormwater Control Measures completed routine 1725 maintenance procedures. • 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. • Vegetation, sediment and trash removal maintenance was conducted prior to the accomplishment of the semiannual qualitative monitoring of 87 outfalls. G. Monitoring & Evaluation As required by Part II, 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 listed 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.
