It <br />considered any natural hazard responsible for releasing 500 or more barrels of oil a <br />significant impact. Additionally, hazards which could release large quantities of <br />household hazardous materials were considered. <br />A JRC Science and Policy Report is helpful in determining the frequency of natural <br />hazard induced HazMat incidents. The report analyzed the U.S. Department of <br />Transportation's hazardous liquid transmission pipeline incident data from 1986-2012. <br />The review included crude, hot, and white oil (paraffin, liquid petroleum, etc.) products <br />in pipelines, terminals, tank farms, pumps, and metering stations. This report <br />determined 5.5% of all oil industry spills in the United States were due to natural <br />hazards.95 <br />95 Girgin, Serkan, and Elisabeth Krausmann.
