Permit No. VA0088641 Page 15 of 42 3) High Priority Municipal Facilities (a) The permittee shall maintain a list of all high priority municipal facilities that do not require a separate VPDES industrial stormwater permit, as well as identify which of the high priority municipal facilities have a high potential of discharging pollutants. Facilities with a high potential for discharging pollutants are those facilities where any of the following materials or activities occur and are expected to have exposure to stormwater resulting from rain, snow, snowmelt, or runoff: (1) Areas where residuals from using, storing or cleaning machinery or equipment remain and are exposed to stormwater; (2) Materials or residuals on the ground or in stormwater inlets from spills or leaks; (3) Material handling equipment (except adequately maintained vehicles); (4) Materials or products that would be expected to be mobilized in stormwater runoff during loading/unloading or transporting activities (e.g., rock, salt, fill dirt); (5) Materials or products stored outdoors (except final products intended for outside use where exposure to stormwater does not result in the discharge of pollutants); (6) Materials or products that would be expected to be mobilized in stormwater runoff contained in open, deteriorated or leaking storage drums, barrels, tanks, and similar containers; (7) Waste material except waste in covered, non-leaking containers (e.g., dumpsters); (8) Application or disposal of process wastewater (unless otherwise permitted); or (9) Particulate matter or visible deposits of residuals from roof stacks, vents or both not otherwise regulated (i.e., under an air quality control permit) and evident in the stormwater runoff. (b) The permittee shall develop and/or update and implement individual stormwater pollution prevention plans for each high-priority municipal facility identified under Part I.B.2.i)3)(a) no later than 36- months after the effective date of this state permit. Stormwater pollution prevention plans (SWPPP) shall include: (1) A site description that includes a site map identifying all outfalls, direction of flows, existing source controls and receiving water bodies; (2) A discussion and checklist of potential pollutants and pollutant sources; (3) A discussion of all potential non-stormwater discharges; (4) A maintenance schedule for all existing source controls; (5) All policies and procedures implemented at the facility to ensure source reduction; (6) An inspection schedule and checklist to ensure that all source reductions are continually implemented and all source controls are appropriately maintained. The date of each inspection and associated findings and follow-up shall be logged in each SWPPP; (7) Appropriate training as required in Part I.B.2.k); (8) Procedures to conduct an annual comprehensive site compliance evaluation;
