The following section applies to all indoor and outdoor bulk deicer storage facilities (temporary and permanent) including salt piles, salt bag storage, salt/sand piles and other storage of deicing materials on commercial, institutional, and non-NPDES permitted industrial properties within the city.
(1) 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.
(2) All salt, salt/sand mix and other deicing materials stored outdoors must be covered at all times.
(a) 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).
(b) The cover must prevent runoff and leachate from being generated by the outdoor storage piles.
(c) 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.
(3) Facility siting.
(a) Outdoor storage of deicing materials must be located on an impervious surface.
(b) Each facility must be located outside of floodplains and 75 feet from lakes, rivers, streams, ditches, wetlands and any other areas likely to absorb runoff.
(c) The property must be sloped away from the facility's deicer storage area.
(d) Practices must be implemented in order to reduce exposure (e.g., sweeping, diversions, and/or containment) when transferring deicing material.
