HB 4678 Michigan House · 2025-2026 Regular Session

Agriculture: weights and measures; certain definitions; provide for. Amends 1964 PA 283 (MCL 290.601 - 290.635) by adding sec. 28g. TIE BAR WITH: HB 4679'25

HB 4678 allows equipment rental businesses to sell motor fuel directly to customers renting fuel-powered equipment (like generators or construction tools) using two clear methods: a flat fee in the rental contract or a per-gallon charge measured by a certified dispenser. It requires all fuel sales to use a "qualified dispenser" (a 110-gallon or smaller container with precise measurement, safety features, and U.S. DOT compliance) and defines key terms like "qualified equipment renter" (businesses renting fuel-powered tools for over 25% of revenue). The bill specifically targets small rental locations selling under 3,000 gallons annually and ties its implementation to another bill passing first. It updates Michigan's Weights and Measures Act to standardize fuel sales practices for this sector without changing tax rates or creating new fees.

MINOR

The bill was revised from a House version to a Senate substitute, primarily adding a requirement that motor fuel sold to equipment renters must meet national air quality standards. The Senate version also reorganized the definitions section and updated the effective date clause to reference a companion bill without a specific request number.

Scope change

The scope of the bill's requirements was expanded to include environmental compliance standards for the fuel itself, whereas the original version focused only on how the fuel is sold and measured.

REQUIREMENT

Added a new requirement that all motor fuel sold by qualified equipment renters must meet United States Environmental Protection Agency national ambient air quality standards.

DEFINITION

Reorganized the definitions section to clarify the list of qualified rental equipment and moved the definition of 'qualified equipment rental location' to appear earlier in the text.

TIMELINE

Updated the effective date clause to reference the companion bill (HB 4679) without including the specific legislative request number found in the House version.
