The U.S. Environmental Protection Agency (EPA), Washington, D.C., has proposed new rules to reduce the emission of air pollutants from “other solid waste incinerators” (OSWI). OSWI include institutional waste incinerators — located at sites such as schools — and very small municipal incinerators, which burn less than 35 tons per day of municipal solid waste. The proposed rules were published in the Federal Register on Dec. 9. Comments on the proposal can be submitted for 60 days following publication. To view the rules in the Register, visit www.gpoaccess.gov/fr/ and enter “other solid waste incinerators” in the 2004 search engine. Then, click on “Standards of Performance for New Stationary Sources and Emission.”
