The U.S. Environmental Protection Agency (EPA) has issued a final rule concluding that seven states had not submitted complete State Implementation Plans (SIPs) for the 2008 National Ambient Air Quality Standards (NAAQS) for lead. 78 Fed. Reg. 12,961 (2/26/13) EPA says three of the states, Hawaii, Illinois and Massachusetts, submitted plans that covered everything but Prevention of Significant Deterioration-related requirements and that EPA already had a Federal Implementation Plan (FIP) in place to address them. Accordingly, no legal deadlines are associated with the findings for these states.
The remaining states, New Jersey, Oregon, Vermont, and Washington, either did not submit a SIP for the lead NAAQS at all or did not submit SIPs that meet all of the lead requirements. For those states, the notice triggers a 24-month clock under which either an approvable SIP must be submitted or a FIP will be put in place. According to EPA, the agency “is committed to working with these states to expedite submissions” to finalize SIPs for each.
