(A) Indoor operations for the storage of deicing materials must be provided whenever possible in order to prevent such material from being affected by rain, snow, or melt water.
(B) All salt, sand, and other deicing materials stored outdoors must be covered at all times. When not using a permanent roof, a waterproof impermeable, flexible cover must be placed over all storage piles. 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.
(C) Facility siting.
(1) The facility must be in close proximity to the area in which the deicing materials are to be used, if practical.
(2) Each facility must be located outside of floodplains and 200 feet 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 surface water features, water supplies, wells or drywells.
(3) A facility must be located on impermeable surfaces.
(4) The property's slope must be away from the facility's salt, deicer, and sand storage area.
(5) Salt vulnerable 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 areas include, but are not limited to:
(a) Areas with salt sensitive vegetation;
(b) Areas serving as a source of drinking water (surface water and groundwater);
(c) Areas with bodies of water with low dilution, low volume, or salt sensitive species; or
(d) Areas associated with groundwater recharge zones or shallow water table, with medium to high permeable soils.
(6) Snow piles. 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.
(7) Transfer of materials. Practices must be implemented in order to reduce exposure (e.g., sweeping, diversions, and/or containment) when transferring salt or other deicing material.
