The Army Corps of Engineers regulates pipeline rights of way and waterway crossing. Pipeline rights of way are defined parcels of land where pipelines and related equipment are installed under- and above ground. Utilities have rights to access public and private land to inspect and maintain their facilities. The right of way is usually mowed and cleared of trees, high shrubs and other obstructions on an annual basis.
The Department of Energy regulates energy supplies and refinery operations.
TSA regulates security for all transportation-related operations, including pipelines, gas plants and docks.
The U.S. Fish and Wildlife Service regulates pipeline rights of way and facility siting impacts. It also administers the Endangered Species Act, which intends to protect and recover species subject to potential extinction.
PHMSA regulates and ensures the safety and integrity of pipelines.
The Environmental Protection Agency handles emissions tracking and reporting for air emissions, water, waste and spills.
The commission requires that all tariffs for gas transmission must be filed electronically, which may include gathering rates.
Most states implement Pipeline and Hazardous Materials Safety Administration regulations for intrastate gathering lines, and some states also regulate other aspects of gathering (siting, economics, etc.). States sometimes implement Environmental Protection Agency regulations, and some states have open access-type rules.
