Manufactured Gas Plants and the National Priorities List: A Technical Review. Topical Report August 1988-July 1989

摘要

The United States Environmental Protection Agency estimates that there are between 1,000 and 1,500 manufactured gas plant (MGP) sites in the United States. Many of these sites are listed in the Comprehensive Environmental Compensation and Liability Act Information System (CERCLIS), and eight sites are listed on or proposed for the National Priorities List (NPL). Seven of the eight MGP sites that are listed or proposed for the NPL are contaminated with tar associated with the manufacture of coal gas. A research project under the Gas Research Institute program for the management of MGP sites to determine why these seven MGP sites were proposed for the NPL. The study explores factors that triggered the discovery of each site and identifies those factors that confirm the sites as NPL candidates. The objective of the study is to assist in defining key risk issues and technology options at MGP sites and developing site management strategies.
