Any emergency generator, whether or not located on a military installation as defined in § 15.2-2201 of the Code of Virginia, that has been certified in accordance with 9VAC5-20-230 by the U.S. Department of Defense or relevant branch of the U.S. Armed Forces to the department as mission-critical and essential to the defense of the United States may operate up to 50 hours per year for non-emergency purposes, including planned outages and switch gear and related electrical system testing. Such non-emergency operation shall be consistent with the requirements for emergency engines pursuant to 40 CFR 60.4211(f)(3), 40 CFR 60.4243(d)(3), and 40 CFR 63.6640(f)(3) and (4).

Each owner of such emergency generator, whether or not located on a military installation as defined in § 15.2-2201 of the Code of Virginia, shall maintain a copy of each certification, or revision thereof, submitted to the department in accordance with 9VAC5-40-50 or 9VAC5-50-50, as applicable. In accordance with 9VAC5-20-230, any certification shall be revised and submitted to the department upon a determination that the provisions of this section no longer apply. These certifications shall be maintained for the life of each applicable emergency generator.
