The use of risk assessment in clean closure equivalency demonstration
This paper describes the use of risk assessment in a clean closure equivalency demonstration for a 127-acre wastewater treatment lagoon at a chemical manufacturing facility in southeast Texas. It presents a case study of a RCRA permittee successfully using a realistic risk assessment to eliminate the barriers to returning valuable industrial land to produce use. The lagoon was built in 1963 adjacent to an industrial ship channel. Beginning in 1967 and continuing until November 1983, the lagoon was used to treat process wastewater from a nearby petrochemical manufacturing site. Ecological impacts of the discharge of ground water into an adjacent surface water body were evaluated. Constitutents of concern are 2-butanone, acetone, benzene, carbon disulfide, 1,4-dioxane, ethylbenzene, 4-methyl-2-pentanone, styrene, toluene, vinyl chloride, xylenes, phthalates, bis(2-chloroisopropyl)ether, polynuclear aromatic hydrocarbons, and Appendix IX metals.
