AGA Comments on EPA GHG Inventory – Update Natural Gas Emissions Estimates from Local Distribution
On January 14, 2016, AGA provided EPA with comments on the Agency’s proposal to incorporate new data on natural gas emissions from the natural gas distribution segment into EPA’s Inventory of U.S. Greenhouse Gas Emissions and Sinks (GHGI). Most of the new data comes from the March 2015 Washington State University Study by Dr. Brian Lamb that AGA co-sponsored with 13 AGA member utility companies and the Environmental Defense Fund (EDF). The Lamb study also incorporated data from the 2009 GTI study on residential, commercial and industrial customer metering and regulating equipment. AGA supported the incorporation of new emission factors where the factors were based on robust data sets. Where robust emission factors are not available, AGA offered to assist EPA in collecting this information so that the inventory can reflect the trend of decreasing emissions from the natural gas distribution sector. As EPA indicated in its proposal, the net result of incorporating the new, more robust emission factors will be to significantly reduce EPA’s estimate of the current level of methane emissions from U.S. natural gas distribution operations.
