School districts; require to test liquefied petroleum gas piping systems in their facilities.

New Section 10 amends Mississippi Code Section 77-11-405 to require pressure testing of natural gas piping systems in school facilities, expanding the bill beyond its original LPG-only focus.

The long title was expanded to reference the amendment to Section 77-11-405 regarding natural gas testing, reflecting the broadened scope of the bill.

Phased implementation for natural gas testing: 50% of systems must be tested by January 1, 2027 (reported before the 2027-2028 school year), and the remaining 50% by January 1, 2028 (reported before the 2028-2029 school year).

After January 1, 2028, annual pressure tests on all natural gas piping systems in school facilities are required, with results reported to the facility's natural gas supplier before the start of each academic year.

Schools operating on a year-round calendar must complete and report natural gas pressure tests by July 1 of the year in which the test is performed, rather than before the start of the school year.

A natural gas piping pressure test performed under a municipal code satisfies the state's pressure testing requirements, creating a mutual recognition provision between local and state standards.
