Kinder Morgan Energy Partners, L.P.-Clear Lake - Executive Summary |
The Kinder Morgan Energy Partners, L.P. - Clear Lake Terminal is a propane truck loading terminal. 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 four 63,000 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. The facility is subject to and complies with Occupational Safety and Health Administration's (OSHA) regulations, including the process safety management (PSM) requirements.

Facility personnel undergo operations competency training and testing, and emergency response training. The facility is inspected and audited on a compliance schedule. The maximum quantity of propane that could be stored on site is 227,000 gallons (967,000 pounds). The worst case release scenario is failure of one "bullet" tank of propane filled to the greatest amount allowed, 56,100 gallons (239,000 pounds), resulting in a vapor cloud explosion. The worst case scenario vapor cloud explosion would potentially affect nearby public receptors. The facility has not had any chemical release accidents since starting operations in 1963. |
