Aquatic Life Criteria for Cadmium in Oregon
The Environmental Protection Agency (EPA) is establishing a federal Clean Water Act (CWA) aquatic life criterion for freshwaters under the state of Oregon's jurisdiction, to protect aquatic life from the effects of exposure to harmful levels of cadmium. In 2013, EPA determined that the freshwater acute cadmium criterion and freshwater acute and chronic copper criteria that Oregon adopted in 2004 did not meet CWA requirements to protect aquatic life in the state. Since that time, the state adopted revised criteria for copper (which EPA is approving in parallel with this final rulemaking), but has not adopted a revised acute criterion for cadmium and thus EPA is establishing a federal freshwater acute criterion for cadmium that takes into account the best available science, EPA policies, guidance and legal requirements, to protect aquatic life uses in Oregon.
Approval and Disapproval and Promulgation of Air Quality Implementation Plans; Interstate Transport for Wyoming
The Environmental Protection Agency (EPA) is taking final action on portions of six submissions from the state of Wyoming that are intended to demonstrate that the State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA). These submissions address the 2006 and 2012 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS), 2008 ozone NAAQS, 2008 lead (Pb) NAAQS, 2010 sulfur dioxide (SO2) NAAQS and 2010 nitrogen dioxide (NO2) NAAQS. The interstate transport requirements under the CAA consist of four elements (or prongs): Significant contribution to nonattainment (prong 1) and interference with maintenance (prong 2) of the NAAQS in other states; and interference with measures required to be included in the plan for other states to prevent significant deterioration of air quality (prong 3) or to protect visibility (prong 4). Specifically, the EPA is approving Wyoming's submissions for interstate transport prongs 1 and 2 for the 2008 Pb and 2010 NO2 NAAQS, and approving prong 1 and disapproving prong 2 for the 2008 ozone NAAQS. The EPA is also approving interstate transport prong 4 for the 2008 Pb and 2010 SO2 NAAQS, and disapproving prong 4 for the 2006 PM2.5, 2008 ozone, 2010 NO2 and 2012 PM2.5 NAAQS.
Approval of Air Quality State Implementation Plans; Nevada; Infrastructure Requirements To Address Interstate Transport for the 2008 Ozone NAAQS
The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the Nevada Division of Environmental Protection (NDEP) to address the interstate transport requirements of Clean Air Act (CAA) with respect to the 2008 ozone national ambient air quality standard (NAAQS). We are approving the portion of the Nevada SIP pertaining to requirements prohibiting significant contributions from Nevada to nonattainment or interference with maintenance in another state.
Approval and Promulgation of Air Quality Implementation Plans; State of Utah; Revisions to Nonattainment Permitting Regulations
The EPA is taking final action to conditionally approve all but one of the State Implementation Plan (SIP) revisions submitted by the State of Utah on August 20, 2013, with supporting administrative documentation submitted on September 12, 2013. These submittals revise the Utah Administrative Code (UAC) that pertain to the issuance of Utah air quality permits for major sources in nonattainment areas. The EPA is not taking final action on the portion of the August 20, 2013 submittal that revised rule R307-420 at this time. The EPA is taking final action to conditionally approve the other revisions because, while the submitted revisions to Utah's nonattainment permitting rules do not fully address the deficiencies in the state's program, Utah has committed to address additional remaining deficiencies in the state's nonattainment permitting program no later than a year from the EPA finalizing this conditional approval. Upon the EPA finding of a timely meeting of this commitment in full, the final conditional approval of the SIP revisions would convert to a final approval of Utah's plan. This action is being taken under section 110 of the Clean Air Act (CAA) (Act).
Findings of Failure To Submit State Implementation Plan Submittals for the 2008 Ozone National Ambient Air Quality Standards (NAAQS)
The Environmental Protection Agency (EPA) is finding that 15 states and the District of Columbia have failed to submit State Implementation Plan (SIP) revisions in a timely manner to satisfy certain requirements for the 2008 ozone National Ambient Air Quality Standards (NAAQS) that apply to nonattainment areas and/or states in the Ozone Transport Region (OTR). As explained in this action, consistent with the Clean Air Act (CAA) and EPA regulations, these findings of failure to submit establish certain deadlines for the imposition of sanctions, if a state does not submit a timely SIP revision addressing the requirements for which the finding is being made, and for the EPA to promulgate a Federal Implementation Plan (FIP) to address any outstanding SIP requirements.
Approval and Promulgation of State Implementation Plans; Interstate Transport for Utah
The Environmental Protection Agency (EPA) is taking final action on a portion of a January 31, 2013 submission and a December 22, 2015 supplemental submission from the State of Utah that are intended to demonstrate that the Utah State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2008 ozone National Ambient Air Quality Standards (NAAQS). The interstate transport requirements under the CAA consist of four elements: Significant contribution to nonattainment (prong 1) and interference with maintenance (prong 2) of the NAAQS in other states; and interference with measures required to be included in the plan for other states to prevent significant deterioration of air quality (prong 3) or to protect visibility (prong 4). Specifically, the EPA is approving interstate transport prong 1 for the 2008 ozone NAAQS.
