ANSI Seeks Comments on Work Item Proposal for Natural Gas Filling Stations


New York, Mar 19, 2009

The International Association for Natural Gas Vehicles (IANGV) has submitted two new work item proposals to the International Organization for Standardization (ISO) on liquefied natural gas (LNG) and compressed natural gas (CNG) vehicle filling stations. As the U.S. member body to ISO, the American National Standards Institute (ANSI) invites all interested U.S. stakeholders to submit comments by May 1, 2009.

The first proposal seeks to address the design and construction of LNG filling stations for vehicles, including equipment, safety devices, maintenance, and periodic inspection. LNG – gas that has been converted temporarily to liquid form for ease of storage or transport – is being used increasingly to fuel vehicles in many countries, including the United States, the United Kingdom, Australia, and Korea.

The second work item proposal calls for guidelines on the design and construction of CNG filling stations for vehicles, including equipment, safety devices, maintenance, and periodic inspection. A fossil fuel substitute for gasoline, diesel, and propane fuel, CNG has had a rise in use as a vehicle fuel in recent years as well.

According to IANGV, concerns about security of oil supply, local air pollution, and greenhouse gases, as well as the decreasing supply and rising prices of gasoline and diesel, will continue to increase usage of LNG and CNG worldwide.

All comments on the two proposals should be sent to Steven Cornish, ANSI senior director for international policy (scornish@ansi.org). Feedback received by the May 1 deadline will be compiled for consideration in the development of a recommended ANSI position and comments, which will then be presented to the ANSI ISO Council (AIC) for formal approval.
