PA-GP5a draft gas compressor station methane reduction permit would require SCR on new/modified LB gas SI RICE >1,380 bhp to meet 0.05 g/bhp-hr NOx limits.

February 3, 2017

On December 8, 2016 the Pennsylvania Department of Environmental Protection (DEP) published a presentation on the state’s proposed “Methane Reduction Strategies for Natural Gas Operations” prepared by DEP’s Air Quality Technical Advisory Committee.

The presentation identifies rich and lean burn stationary natural gas-fired spark ignition engines as being among methane reduction sources included in a proposed update of its current general permit (GP-5) for sources at natural gas compression, processing, and transmission facilities.

It also lists stationary natural gas-fired spark ignition engines among sources for which DEP proposes to develop a new General Permit for new or modified unconventional well sites and remote pigging stations (GP5A).

DEP has also recently published a draft General Plan Approval and General Operating Permit defining emission limits for new or modified sources at natural gas compressor stations, processing plants and transmission stations.

Of special note to Emissions Monitor readers is the draft operating permit’s lower NOx limit of 0.05 g/bhp-hr for lean burn spark ignited engines greater than or equal to 1,380 bhp (see table on page 16). Selective Catalytic Reduction (SCR) would be required to reach this lower NOx level.

The state plan must require that the emission controls be implemented as soon as practicable but no later than January 1, 2021.

What this means to you
Pennsylvania DEP’s draft General Plan Approval and General Operating Permit to achieve its “Methane Reduction Strategies for Natural Gas Operations” requires emission controls be implemented as soon as practicable, and no later than January 1, 2021. NOx limits of 0.05 g/bhp-hr for Lean Burn SI engines >1,380 bhp would require SCR control systems.
