Risk - Based Methodologies for Evaluating Petroleum Hydrocarbon Impacts at Oil and Natural Gas E&P Sites The process of calculating human health risk - based screening levels for total petroleum hydrocarbons (TPH) is described in an easy - to - understand question and answer format. [Risk - ba sed screening levels (RBSLs) are chemical - specific concen trations in environmental media that are considered protective of human he alth.] Risk assessment concepts developed by the U.S. Environmental Protection Agency and research groups such as the Petroleum Environmen tal Research Forum and the Total Petroleum Hydrocarbon Criteria Workin g Group are used to calculate RBSLs for TPH in crude oil and condensates ob tained from around the world. These methodologies were also applied to polyaromatic hydrocarbons, metals, and benzene in TPH. Addition al resources contained in this manual include a description of the physical and chem ical characteristic s of crude oil, condensate, and exploration and prod uction (E&P) wastes (contrasted with refined products), a summary of the fede ral regulatory status of E&P wastes, and a listing of key equations used for calculating RBSLs
