Withdrawal of Approval for Use of Phosphogypsum in Road Construction
The Environmental Protection Agency (EPA) is withdrawing its October 14, 2020 approval for use of phosphogypsum in government road projects. Under the Clean Air Act, the EPA may approve a request for other use of phosphogypsum if it includes certain prescribed information. Upon further review, EPA has determined that the approval was premature and should be withdrawn because the request did not contain all of the required information. With this action, phosphogypsum remains prohibited from use in road construction projects.
Air Plan Approval; AL; NOX
The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) revision submitted by the State of Alabama through a letter dated February 27, 2020, to add regulations maintaining compliance with the State's nitrogen oxides (NOX) SIP Call obligations for large non-electricity generating units (non-EGUs), to repeal the State's previously sunsetted NOX Budget Trading Program regulations, and to repeal the State's Clean Air Interstate Rule (CAIR) regulations. EPA is also conditionally approving into the SIP state regulations that establish monitoring and reporting requirements for units subject to the NOX SIP Call, including alternative monitoring options for certain sources for NOX SIP Call purposes. In addition, EPA is making ministerial changes to reflect the State's renumbering of an existing regulation for ``New Combustion Sources.''
Air Plan Approval; FL; Prevention of Significant Deterioration Infrastructure Elements
The Environmental Protection Agency (EPA) is approving revisions to the Florida State Implementation Plan (SIP), submitted by the Florida Department of Environmental Protection (FDEP), Division of Air Resources Management, to EPA on August 26, 2020. The Clean Air Act (CAA or Act) requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each national ambient air quality standard (NAAQS) promulgated by EPA, commonly referred to as an ``infrastructure SIP.'' This submission addresses certain greenhouse gas (GHG) Prevention of Significant Deterioration (PSD) permitting requirements for the 2008 and 1997 8-hour Ozone and the 1997 Annual and 2006 24-hour Fine Particulate Matter (PM2.5) NAAQS. Additionally, EPA is converting the previous disapprovals of Florida's infrastructure SIPs related to the CAA GHG PSD permitting requirements for the above NAAQS to full approvals.
