On December 1, 2011, the Pennsylvania Department of Environmental Protection issued a technical guidance explaining the use of natural gas conversion systems, which are permitted under the Pennsylvania Clean Vehicle Program. Under the program, conversion systems that have been approved by the United States Environmental Protection Agency or the California Resources Air Board may be installed on vehicles in Pennsylvania. According to DEP's statement, when used as a transportation fuel, natural gas "emits fewer pollutants, such as volatile organic compounds and nitric oxide" than traditional diesel or gasoline. The Policy on Clean Alternative Fuel Conversion Systems was published in the Pennsylvania Bulletin on December 3, 2011.
