HF 2671 Iowa House · 2025-2026 Regular Session

A bill for an act relating to matters under the purview of the department of administrative services, including rules for capitol complex events and the compatibility of passenger vehicles rented or leased by the state with biodiesel blended fuel classified as B-20 or higher, and including effective date and applicability provisions.

This bill requires Iowa state agencies to ensure that any passenger vehicle rented or leased with a diesel engine can use biodiesel fuel blended at 20% or higher (B-20). Specifically, it mandates that private vendors must provide manufacturer documentation confirming the vehicle's engine is compatible with B-20 biodiesel before being awarded state contracts. The requirement applies to all new or renewed rental/lease contracts issued on or after July 1, 2026. It extends an existing certification rule currently used for state vehicle purchases to the rental/lease procurement process. The bill does not mandate biodiesel use but ensures state vehicles can utilize this fuel type if chosen.

The bill was converted from an official 'Enrolled' version signed by the Governor into a 'Reprinted' version for public distribution.

Scope change
No change to the bill's scope, applicability, or legal effect; the document format was updated for public record purposes.
TECHNICAL

Added a header identifying the document as a reprint by the Committee on State Government and noting it is a successor to HSB 708.

Added the date the bill passed the House (March 5, 2026) to the reprint version.

Removed the official signature block from the Governor and Speaker of the House, as this version is a reprint rather than the final enrolled copy.
