EPA issues greenhouse gas permit for $607m Tenaska Roan’s Prairie plant

The U.S. Environmental Protection Agency (EPA) has issued a final greenhouse gas (GHG) air permit allowing construction of the Tenaska Roan’s Prairie power plant in Grimes County, Texas.

EPA said Aug. 1 that it has issued the GHG Prevention of Significant Deterioration (PSD) construction permit for the project. The company plans to construct three gas-fired turbines for power generation.

Once completed, the facility will provide up to 694 MW (nominal gross) of power to supplement the Texas power grid during peak demand.

The facility will consist of three simple-cycle, gas-fired turbines, as well as a diesel-fired emergency generator and a diesel-fired fire pump engine. The projected is expected to bring $607 million in economic development, 150 construction jobs and ten full-time positions, according to an EPA news release.

EPA’s final permit held that the power plant would pass muster when it came to issues like the National Historic Preservation Act (NHPA) and the Endangered Species Act (ESA).

In June 2010, EPA finalized national GHG regulations, which specify that beginning on January 2, 2011, projects that increase GHG emissions substantially will require an air permit.

Texas is working to replace the federal implementation plan with its own state program, which will eliminate the need for businesses to seek air permits from EPA.

EPA has finalized 46 GHG permits in Texas, proposed an additional five permits and currently has 14 additional GHG permit applications under review and permit development in Texas.

On Aug. 1, EPA Region 6 also announced a final permit for the Pinecrest Energy Center LLC gas plant in Angelina County, Texas,
