The facility handles quantities of propane in excess of the Environmental Protection Agency's Risk Management Planning (RMP) threshold planning quantity for a flammable substance. The facility is considered a RMP program 3 facility. 
The facility receives propane via a U.S. Department of Transportation-regulated pipeline, stores propane in one 75,000 gallon "bullet" tanks ("water" capacity), and loads propane onto highway trucks using two truck loading racks and product pumps. The facility also has storage capacity for up to 13,000 pounds of ethyl mercaptan, an odorant that is injected into the propane for safety.
