PURPOSE: This rule provides for procedures or requirements for activities as part of oil 10 CSR 50-2

and gas production operations. General operations include hydrocarbon storage, metering of produced gas, and spill response.

1. (1) Tank identification. All oil tanks, tank batteries, tanks used for produced water collection or disposal, and tanks used for oilsediment treatment or storage shall be identified by a sign posted on, or not more than fifty feet (50') from, the tank or tank battery. The sign shall be of durable construction and shall be large enough to be legible under normal conditions at a distance of fifty feet (50'). The sign shall identify—

   1. (A) Name, license number, and contact information of the operator;
   2. (B) Name of the lease or unit being served by the tank;
   3. (C) Location of the tank, including section, township, range, and county; and
   4. (D) Contents of the tank.

2. (2) Gas to be metered. All gas, when produced or sold, shall be metered with a meter of sufficient capacity. Meters shall not be required for gas produced and used on site for development purposes, production unit operations, primary dwellings, or non-commercial gas wells.

   1. (A) Each party who owns, maintains, or operates the metering device used to record gas sales from each well or production unit in a gas field shall, at a minimum, test and calibrate the metering device on an annual basis and retain the record of the testing and calibration for at least two (2) years. Each party shall also retain, for at least two (2) years, the original field record consisting of meter charts, electronic records, records of gas purchases, or other approved method. All information retained shall be made available to the state geologist upon request.
   2. (B) By-passes shall not be connected around meters in a manner that will permit the improper taking of gas.
3. (3) Spill Notification. Each operator, immediately upon discovery or knowledge of any spill or release, shall take immediate action in accordance with the Spill Bill, section 260.500 to 260.550, RSMo, and the implementing regulations in 10 CSR 24. This does not alter responsible parties’ obligations under any other applicable law.
