D.C. Mun. Regs. tit. 15, r. 15-2368
Upon a customer's written application to the Commission, a test shall be made of the customer's meter as soon as practicable that shall be witnessed by a representative of the Commission.
A one dollar ($1) fee shall be paid at the same time of the application by check or money order made payable to the gas corporation.
On receipt of the request from a customer, the Commission shall notify the gas corporation, and the gas corporation shall not knowingly remove or adjust the meter until instructed by the Commission.
The customer, or his or her representative, may be present when the meter is tested but shall not interfere with the testing.
Included in the referee test of the meter shall be a test for the accuracy of the following:
A written report of the results of the test shall be sent to the customer.
If a consumer complaint hearing is held at the Commission pertaining to the meter accuracy, all relevant documentation shall be made a part of the official record.
If the meter is found to over-register or under-register consumption by more than two percent (2%), the gas corporation shall credit the customer for the one dollar ($1) testing fee.
