Sierra Club, Notice of Intent to File Suit Against EPA for Failure to Conduct Triennial Reports to Congress on Environmental and Conservation Impacts of the Renewable Fuel Standard

Sierra Club submitted a notice of intent to file a Clean Air Act citizen suit against EPA for failing to report to Congress triennially on the environmental and resource conservation impacts of the Renewable Fuel Standard (RFS) program. Sierra Club asserted that EPA also had failed to comply with a requirement that it complete an “anti-backsliding” study to determine whether RFS volumes adversely impact air quality.
