PPL gets air permit for dry sorbent injection installation at Brunner Island

The Pennsylvania Department of Environmental Protection said in a brief notice in the May 16 Pennsylvania Bulletin that on April 27 it issued an air permit to PPL Brunner Island LLC for the installation of a mercury dry sorbent injection (MDSI) system to control mercury emissions from the three existing coal-fired utility boilers at the Brunner Island Steam Electric Station.

This 1,411-MW power plant is located in East Manchester Township, York County. The MDSI system will consist of fully enclosed material transfer equipment and two mercury dry sorbent storage silos whose particulate matter (PM) emissions will be controlled by a dedicated bin vent collector during storage silo loading, the notice said.

Brunner Island is one of the PPL Corp. (NYSE: PPL) power plants that is about to be spun off into the newly-created Talen Energy. PPL will contribute to Talen its PPL Energy Supply plants, with other plants being contributed by RJS Power.

Brunner Island is already equipped with scrubbers for SO2 control. Said a May 1 Talen Energy prospectus about compliance with the federal Mercury and Air Toxics Standards (MATS): “Energy Supply and RJS Power are generally well-positioned to comply with MATS, primarily due to recent investments in environmental controls. Energy Supply is evaluating chemical additive systems for mercury control at Brunner Island, and modifications to existing controls at Colstrip for improved emission reductions.” Colstrip is a coal-fired plant in Montana.
