S-2 Spill Prevention, Containment and Control
• Drain or replace motor oil and other automotive fluids in a designated area away from storm sewer
inlets. Collect spent fluids and recycle or dispose of properly. Never dispose of these fluids in the
storm sewer or sanitary sewer.
• In fueling areas, clean up spills with dry methods (absorbents) and use damp cloths on gas pumps and
damp mops on paved surfaces. Never use a hose to “wash down” a fuel spill.
• Where practical, reduce stormwater contact with equipment and materials by implementing indoor or
covered storage, implementing stormwater run-on control measures and following good housekeeping
practices.
Identification of Spill Areas
Identify potential spill areas, potential spill volumes, material types, frequency of material use, and
drainage paths from spill areas with relation to storm sewer inlets, adjacent waterbodies, structural BMPs,
and containment structures. Use this information to determine the types of spill prevention and control
measures needed specific to the site conditions. Examples of potential spill locations include:
• Loading and unloading areas
• Outdoor storage areas
• Outdoor manufacturing or processing activities
• Waste disposal/storage areas
• Areas that generate significant dust or particulates (that may be subsequently deposited on the
ground)
• Salt piles
• Areas prone to spills based on past experience at the site
• Locations where other routine maintenance activities occur such as equipment maintenance and
cleaning, pesticide/fertilizer application, etc.
Additionally, areas where smaller leaks may occur such as parking should also have basic spill cleanup
procedures.
Material Handling Procedures
From a water quality perspective, the primary principle behind effective material handling practices is to
minimize exposure to stormwater. This can be accomplished by storing the material indoors under
weather-resistant covering, elevating the material off the ground by using pallets, and diverting
stormwater around materials storage areas. Representative outdoor materials handling procedures
include:
• Keep bulk solid materials such as raw materials, sand, gravel, topsoil, compost, concrete, packing
materials, metal products and other materials covered and protected from stormwater.
• When practical, store materials on impermeable surfaces.
• Store hazardous materials according to federal, state, and local hazardous materials requirements.
