NPGA Secures Extension on Temperature Compensation Rule

The National Propane Gas Association (NPGA) has secured an anticipated important extension to a rule in the 2024 edition of Handbook-130 regarding temperature compensation for meters.

Originally, the National Institute of Standards and Technology (NIST) published a rule requiring all new meters with a flow rate under 20 gallons per minute to have temperature compensation starting January 1, 2026. The rule also made this requirement retroactive for all existing meters by January 1, 2030.

Recognizing the burden this placed on the industry, NPGA successfully negotiated an extension. Now, the retroactive requirement has been delayed until January 1, 2034, but only for states that adopt the 2026 or later edition of the NIST Handbook.

NIST and the National Conference on Weights and Measures (NCWM) agreed that the original four-year retroactive window was too short and acknowledged that a ten-year period is more reasonable.
