EPA begins ruling process to phase out leaded avgas
With the deadline for the comment period on the Environmental Protection Agency’s advanced notice of proposed rulemaking (ANPRM) to phase out leaded avgas

With the deadline for the comment period on the Environmental Protection Agency’s advanced notice of proposed rulemaking (ANPRM) to phase out leaded avgas having just passed, many in the industry remain galvanized for possible effects of the proposed mandate.

The EPA published the ANPRM at the end of April, stating its intention to determine whether emissions from aircraft using leaded aviation gasoline (avgas) cause or contribute to air pollution, which can endanger public health. While the Industry Avgas Coalition, a group consisting of aviation associations such as NBAA, AOPA and NATA, along with petroleum industry representatives asked the agency to extend the deadline to the end of October, the EPA settled on August 27.
