Morris Compressor Station is located in Richhill Township, Greene County, PA. Natural gas from off-site wells is brought in via pipeline to be compressed and dried prior to being piped off site. The site comprises eight (8) natural gas fired reciprocating compressor engines, two (2) dehydration units, and supporting process equipment and emission control devices including tanks, vapor destruction unit/vapor recover unit, flares, emergency generators, truck loadout appurtenances, and associated pipeline pigging chambers.
Upwind and downwind air quality monitoring equipment measuring PM2.5 (particulate matter) and VOCs known as BTEX was installed within 500’ of the station pad center.
The prevailing wind direction for this region is from the south-southwest. CNX positioned the PM2.5 monitors such that one would be subject to winds from upwind of the station and the other would be in the path of wind traveling across the station pad (downwind).
