CO HB1372

Establishes an exemption from Colorado air emission limits for stationary engines used to support critical military infrastructure during emergency events, such as loss of utility service or natural disasters.

Limits the exemption to engines providing power to military facilities or facilities under control of the U.S. Department of Defense that comply with federal standards (40 CFR 60, Subparts IIII and JJJJ as of January 1, 2022).

Requires operators to minimize engine use, report emergency events within 48 hours or by noon the next business day, and maintain detailed records of operations for five years, including maintenance, monitoring results, and operation procedures.

Mandates annual compliance reports to the state division detailing engine operations, dates, durations, reasons for use, and actions taken to minimize emissions.

Takes effect only upon approval by the federal Environmental Protection Agency's inclusion in Colorado's State Implementation Plan; automatically repeals October 1, 2025 if EPA approval is not obtained by September 1, 2025.
