Ineffective oversight of the federal diesel emissions reduction grant program by the Environmental Protection Agency may have caused EPA to overstate the environmental benefits of the program, according to a new audit by the agency’s inspector general.
The report said that although EPA in 2009 doled out nearly $300 million in Diesel Emissions Reduction Act funding, grant-activity documentation “was not always sufficient to demonstrate that funded work met the specific requirements needed to achieve the desired emissions reductions.”
