The Gas Technology Institute (GTI) is developing guidance on cost-effective and practical solutions to the permitting of fleet maintenance and repair facilities. The guidance will aid facility owners, authorities having jurisdiction (AHJ’s), designers, fire officials, and other stakeholders in interpreting and understanding regulatory requirements of needed modifications to maintenance facilities. GTI is working with industry experts to address necessary maintenance facility and garage upgrades for three major alternative fuels currently being used in heavy duty vehicles: compressed natural gas, hydrogen, and propane. The guidance will address gas detection, ventilation, electrical classification compliance, heating devices, alarm system configuration, and behavior of lighter-than-air fuels.

As of 2019, GTI has developed multiple reports, safety technology summaries, code reports, best practice documents, presentation materials, and videos for each of the three gaseous fuels. These materials are available to the public through the project’s website that features an interactive diagram of a maintenance garage. Using these materials, GTI has conducted online outreach and hosted workshops across the country including at multiple large conferences in Chicago, Illinois; Emeryville, California; Los Angeles, California and Pittsburg, Pennsylvania.
