Metering and Regulating Stations

Metering and regulating stations ensure the safe and efficient delivery of natural gas to customers. Some are located at the city gate stations or at very large customer facilities, although most are located throughout the system. These stations reduce pipeline pressures, allowing gas to be delivered safely through the distribution system within the maximum allowable operating pressure.

Metering and regulating stations also filter natural gas to remove impurities. If the odorant mercaptan is not already present, metering and regulating stations add it to the gas. Because natural gas is odorless, mercaptan adds a strong sulfur-like or rotten-egg odor that helps people detect gas leaks.

Metering and regulating stations always have a standby system and a shutoff valve. Never open or close this valve. Only trained technicians are permitted to operate them.
