PPL nears air permit for new mercury controls at Brunner Island coal plant

PPL Generation LLC is nearing an air permit from the Pennsylvania Department of Environmental Protection 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 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, said the DEP in a notice in the March 28 Pennsylvania Bulletin. The maximum expected increases in facility emissions as a result of the changes proposed are: 0.01 TPY PM; 0.01 TPY PM10; and 0.01 TPY PM2.5. This is a Title V facility.

The department’s review of the information submitted by the applicant indicates that the air contamination sources as constructed or modified will comply with all regulatory requirements pertaining to air contamination sources and the emission of air contaminants including the best available technology (BAT) requirement under Pennsylvania code. Based on these findings, the department proposes to issue a plan approval for the proposed construction.

PPL Generation is part of PPL Corp. (NYSE: PPL), though the 1,411-MW Brunner Island facility is one of the power plants that PPL Corp. plans to spin off within the next few weeks to the newly-formed Talen Energy.
