Noise control designs and post-construction assessments were performed for a natural gas compressor station that was under Federal Energy Regulatory Commission requirements. Compression equipment was housed in three individual buildings, one per project phase. One building housed three reciprocating compressors driven by gas-fired engines; another building housed two centrifugal compressors driven by two different models of turbine engines. The third building housed a single reciprocating compressor. Project challenges included close proximity of the nearest noise sensitive area (less than 800 feet), excessive piping and exhaust noise, coordinating test conditions for equipment that served two different pipelines, and competing area sound sources. Diagnostic sound level measurements were used to rank-order sound sources. Noise control design and additional treatments were evaluated using a computer noise model. Problems were identified, treatments were recommended and implemented, and the station met the noise goal.
