Whenever possible, vehicle and equipment maintenance is performed in an indoor garage. Outdoor vehicle maintenance takes place in an area designated for vehicle maintenance.
(a) The following are the selected BMPs for vehicle and equipment maintenance at the facility:
(1) Equipment will be kept clean so that a buildup of grease and oil will not wash away when the equipment is exposed to rain.
(2) Vehicle and equipment maintenance areas are paved with concrete wherever possible.
(3) Drip pans or containers are kept under the vehicles at all times during maintenance.
(4) Fluids are drained from any retired vehicles kept on-site for scrap or parts, Stored or out-of service vehicles awaiting restoration or service, and vehicles being held for resale are checked periodically for leakage. Drip pans or containers are to be kept under the vehicles.
(5) A berm or other runoff controls will be installed to prevent run-on and run-off Drainage will be directed to a connection to the sanitary sewer system.
(b) Vehicle and equipment storage areas will be operated with some similar precautions:
(1) Vehicles and equipment will be inspected to identify sources of spills or leaks. Designated facility personnel will perform regular walk-by inspection.
(2) The equipment yard will be kept clean and clear of debris and litter because any runoff then becomes an illegal discharge to the storm drain.
(3) Storm drain inlets will be cleaned on a regular schedule and also after large storms. Special attention will be paid to the kinds of potential pollutants that accumulate there as a result of facility activities so that appropriate measures can be taken to control any pollutant sources.
(4) Improvements to a vehicle or equipment storage areas should grade the area to slope to a longitudinal drain, or install curbs to direct all direct storm water to a single point of discharge to easily visually monitor the storm water discharge. If the vehicle or equipment yard is a large source of oily materials, then the inlet will be fitted with an oil/water separator or oil/grease trap.
(5) Consistent parking spots will be designated for each vehicle so that if a leak is indicated on the ground, the truck can be identified and repaired,
(6) A special area will be constructed for the facility’s dirtiest equipment (tar equipment, asphalt paving equipment, etc.) in order to handle the discharges, leaks, and runoff separately with more intensive BMPs.
