(A)   Indoor operations for the storage of deicing materials must be provided wherever possible in order to prevent such materials from being affected by rain, snow and melt water.
   (B)   All salt, sand and other deicing materials stored outdoors must be covered at all times.
      (1)   When not using a permanent roof, a waterproof impermeable, flexible cover must be placed over all storage piles (to protect against precipitation and surface water runoff). The cover must prevent runoff and leachate from being generated by the outdoor storage piles. The cover must be secured to prevent removal by wind or other storm events. Piles must be formed in a conical shape and covered as necessary to prevent leaching.
      (2)   Any roof leaks, tears or damage should be temporarily repaired during winter to reduce the entrance of precipitation. Permanent repairs must be completed prior to the next winter season.
   (C)   The facility must be in close proximity to the area in which the deicing materials are to be used, if practical.
   (D)   Each facility must be located outside of floodplains and [insert distance] from lakes, rivers, streams, ditches, storm drains, manholes, catch basins, wetlands and any other areas likely to absorb runoff. A facility must not be located in close proximity to, within a certain distance of surface water features, water supplies, wells or drywells.
   (E)   A facility must be located on impermeable surfaces.
   (F)   The property slope must be away from the facility's salt, deicer, and sand storage area.
   (G)   Salt vulnerable/intolerant natural areas should be avoided as storage facilities to the extent possible. Where they cannot be avoided, specific measures should be instituted to protect vulnerable areas. Salt vulnerable/intolerable natural areas include, but are not limited to:
      (1)   Areas with salt sensitive vegetation;
      (2)   Areas serving as a source of drinking water (surface water and ground water);
      (3)   Areas with bodies of water with low dilution, low volume or salt sensitive species;
      (4)   Areas associated with ground water recharge zones or shallow water table, with medium to high permeable soils.
   (H)   Snow piles must be located downslope from salt and deicer storage areas to prevent the snow melt from flowing through storage areas and carrying material to the nearest drainage system or waterway.
   (I)   Deicer- and salt-containing truck wash water must be captured, treated, and recycled for use as salt-brine in pre-wetting and anti-icing activities.
   (J)   Practices must be implemented in order to reduce exposure (e.g., sweeping, diversions, and/or containment) when transferring salt or other deicing material.
