Environmental Protection Agency October 21, 2014 – Federal Register Recent Federal Regulation Documents

EPA is approving changes to Wyoming's State Implementation Plan (SIP). On February 10, 2014, the Wyoming Department of Environmental Quality (WDEQ) submitted to EPA revisions to the Wyoming SIP. These revisions included the removal of an exemption from Wyoming Air Quality Standards and Regulations (WAQSR) Chapter 3, section 2(d). In this action, EPA is approving the revision of this provision into the SIP because the revision is consistent with Clean Air Act (CAA) requirements. The revision will correct certain deficiencies related to the treatment of excess emissions from sources. EPA will address the remaining revisions from Wyoming's February 10, 2014 submission in a separate action.

The Environmental Protection Agency (EPA) proposes to approve the State Implementation Plan (SIP) revision submitted by the state of Nebraska to address the requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA) for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS) and the inclusion into the SIP, of Nebraska's conflict of interest provisions. Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated or revised by the EPA. On October 18, 2011, the Nebraska Department of Environemtal Quality (NDEQ) submitted a revision to Nebraska's SIP which describes the State's provisions for implementing, maintaining, and enforcing the standards listed above. In addition, NDEQ submitted on March 11, 2014, a request to include conflict of interest provisions into the Nebraska SIP. These revisions are necessary to properly implement, maintain and enforce the 2008 Pb NAAQS and also recognizes the state's request to include Nebraska's conflict of interest provisions into the SIP.

The Environmental Protection Agency (EPA) proposes to approve the State Implementation Plan (SIP) revision submitted by the state of Missouri on May 8, 2012, related to a Missouri rule titled ``Control of Emissions from Hand-Fired Equipment.'' This SIP revision provides a rule to allow the burning of discarded clean wood in non-residential (commercial owned and operated) heating devices, with restrictions to ensure environmentally-sound operation, in the St. Louis metropolitan area.

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) revision submitted by the state of Iowa for the purpose of approving the 2008, 2009, 2011, 2012, and 2013 updates to the Linn County Air Quality Ordinance. EPA is proposing approval of Iowa's request to include revisions to the Linn County Air Quality Ordinance, Chapter 10, because the revisions improve the stringency of the Iowa SIP.

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the applicable state implementation plan for the State of Nevada submitted by the Nevada Division of Environmental Protection. The revisions include amended State rules related to applications for, and issuance of, permits for stationary sources, but not including review and permitting of major sources and major modifications under parts C and D of title I of the Clean Air Act. EPA is taking action under the Clean Air Act obligation to take action on State submittals of revisions to state implementation plans. The intended effect of the approval is to fix deficiencies in the previously-approved version of the permitting rules and to ensure that new or modified stationary sources do not interfere with attainment or maintenance of the national ambient air quality standards.

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State Implementation Plan (SIP) submitted by the State of Missouri on May 8, 2012, and October 17, 2013, related to a Missouri rule titled ``Restriction of Emission of Particulate Matter from Industrial Processes.'' This action amends the SIP in four ways. The first is it updates an outdated reference in the current SIP approved rule. Second, it provides a hierarchy of compliance measurement approaches for Particulate Matter (PM) emissions from industrial processes. Third, it provides a clarification on applicability of the provisions. And fourth, it deletes redundant definitions.
