In March, the State of New York filed a petition with EPA under Section 126 of the Clean Air Act asserting that nine upwind states were interfering with New York’s compliance with the 2008 and 2015 national ambient air quality standards for ground-level ozone. The CAA directs EPA to respond to CAA §126 petitions in 60 days, but the Act authorizes EPA to extend its time to respond to these petitions for six months. On May 4, EPA issued a notice extending the deadline for the agency to respond to the state’s petition until Nov. 9, citing its authority under CAA §307(d)(10) and the need for the agency to have more time to consider the petition and allow for public participation in the process.
