At its meeting on August 23, 2011, the Arkansas Oil and Gas Commission (AOGC) approved a new rule that will limit the amount of noise a natural-gas compressor station can emit. The new rule will limit the noise levels of a non-wellhead natural gas compressor to 55 decibels, as measured from the exterior of the nearest pre-existing “noise-sensitive area.” A noise-sensitive area is defined as a “private residence … school, hospital, church, nursing home or other building regularly used for overnight accommodations.” Compressor stations re-pressurize natural gas to keep it flowing through a pipeline. They are 40 to 100 miles apart and typically run 24 hours a day.
