ii. No Exposure Certification for High Priority Municipal Facilities
  a) Municipal facilities may qualify for No Exposure Certification (Appendix H) when all
  activities and materials are completely sheltered from exposure to rain, snow,
  snowmelt and/or runoff.

  b) High priority municipal facilities with uncovered parking areas for vehicles awaiting
  maintenance may be considered a low priority municipal facility if only routine
  maintenance is performed inside and all other no exposure criteria are met. Details
  on high/low priority municipal facilities are addressed later in this section.

  c) Municipal facilities accepting or repairing disabled vehicles and/or vehicles that
  have been involved in accidents are not eligible for the No Exposure Certification.

  d) Municipal facilities must maintain the No Exposure Certification and document in
  the SWMP Plan. The No Exposure Certification ceases to apply when activities or
  materials become exposed.

b. Follow a Preventive Maintenance Program
  i. The Village of East Aurora has a preventative maintenance program that includes routine
  inspection, testing, maintenance, and repair of all fueling areas, vehicles and equipment and
  systems to prevent leaks, spills and other releases.
  This includes:
  a) Performing inspections and preventive maintenance of stormwater drainage,
  source controls, treatment systems, and plant equipment and systems;

  b) Maintaining non-structural BMPs (e.g., keep spill response supplies available,
  personnel appropriately trained, containment measures, covering fuel areas); and

  c) Ensuring vehicle washwater is not discharged to the MS4 or to surface waters of
  the State. Washing equipment/vehicles in a designated and/or covered area where
  washwater is collected to be recycled or discharged to the sanitary sewer is required.

  ii. Routine maintenance is performed to ensure BMPs are operating properly.

  iii. When a BMP is not functioning to its designed effectiveness and needs repair or
  replacement:
  a) Maintenance is performed before the next anticipated storm event, or as
  necessary to maintain the continued effectiveness of stormwater controls. If
  maintenance prior to the next anticipated storm event is impracticable, maintenance
  must be scheduled and accomplished as soon as practicable; and

  b) Interim measures are taken to prevent or minimize the discharge of pollutants
  until the final repair or replacement is implemented, including cleaning up any
  contaminated surfaces so that the material will not be discharged during subsequent
