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.

Marathon Technical Services USA Inc. (Marathon) and its partners aim to enhance the safety of gaseous fuel vehicle garages by developing easily understood facility design resources. The resources are aimed at facility owners, consulting engineers, fire marshals and code officials. The development of visual manuals, online and in-person instruction, and case studies will provide a more interactive approach to interpreting codes for garage facility upgrades and building modifications. The guidance is focused on the facilities that store and maintain compressed natural gas (CNG), liquefied natural gas (LNG), liquified petroleum gas (propane or LPG), and compressed hydrogen.

Marathon and Clean Fuels Ohio developed a training manual and presentation materials for each of the four fuels that explains concepts and applications in an easy to understand format. The manuals and presentation materials were used at numerous in-person trainings and facility tours that Marathon hosted across the country in 2018 and 2019. These materials along with narrated, modular training webinars are now hosted on the project website so that users can continue to use and benefit from these resources.
