39 Miss. Admin. Code Pt. V, Ch. 03 - Testing and Reporting

A natural gas piping pressure test performed under a municipal code satisfies the pressure testing requirements prescribed by this section. A pressure test to determine if the natural gas piping in each school facility will hold at least normal operating pressure shall be performed as follows: 1. School facility pipe testing includes all gas piping from the outlet of the purchase meter to each inlet valve of each appliance. 2. The test procedure used must ensure discovery of all potentially hazardous leaks in the segment being tested. 3. For systems on which the normal operating pressure is less than 0.5 psig, the test pressure shall be 5 psig and the time interval shall be thirty (30) minutes. 4. For systems on which the normal operating pressure is 0.5 psig or more, the test pressure shall be 1.5 times the normal operating pressure or 5 psig, whichever is greater, and time interval shall be thirty (30) minutes. 5. A pressure test using normal operating pressure shall be utilized only on systems operating at 5 psig or greater, and the time interval shall be one hour.#

102The testing shall be conducted by a licensed plumber.#

103During the pressure test, each system supply inlet and outlet in the school facility must be closed.#

104The testing shall be completed annually, no later than July 1.#

105A person responsible for a school facility shall provide written notice to the natural gas supplier specifying the date and result of each pressure test or inspection no later than July 15, annually. The results of the annual pressure test in any school facility must also be reported to the State Department of Education within thirty (30) days of testing.#

106If the school facility operates on a year-round calendar, the results of the required pressure testing must be completed and reported to the facility's natural gas supplier no later than July 1 of the year in which the pressure test is performed.#

107If any leaks are identified during the test, the firm or individual conducting the test shall immediately report such findings as follows: 1. For all school facilities, an identified natural gas leakage shall be reported to the natural gas supplier and the State Department of Education. 2. In a public school facility, an identified natural gas leakage shall also be reported to the person responsible for the school facility and to the board of trustees of the school district. 3. In a charter or private school facility, an identified natural gas leakage shall also be reported to the person responsible for the school facility.#
