EPA proposes permit for federal coal-fired power plant’s switch to natural gas

The U.S. Environmental Protection Agency (EPA) is seeking public comment on a proposed permit for the Capitol Power Plant in Washington D.C. to allow the plant to burn natural gas instead of coal.

The Plantwide Applicability Limit permit would establish a site-wide emissions cap for greenhouse gases, nitrogen dioxide and particulate matter at the power plant, and reduce the permitting burden for the plant in exchange for limiting its ability to increase emissions. The permit does not authorize construction of the project, but it streamlines the permitting process, which is handled by the D.C. Department of Environment.

The Capitol plant was built in the early 1900’s and provides steam for heat and chilled water for cooling to nearby federal buildings, including the U.S. Capitol. The operator, the Architect of the Capitol, said it intends to install two natural gas-fired cogeneration units to provide steam and electricity to the Capitol and nearby buildings.
