Environmental Protection Agency July 2018 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) submission, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), on October 24, 2017, and a portion of a December 9, 2015, infrastructure SIP submission. The October 24, 2017 submission addresses the general Clean Air Act (CAA or Act) conflict of interest requirements applicable to Alabama state boards or agency personnel with respect to the approval of permits or enforcement orders. This submission also specifically addresses requirements for implementation of the following national ambient air quality standards (NAAQS): 1997, 2006, and 2012 Fine Particulate Matter (PM2.5), 2008 8-hour Ozone, 2008 Lead, 2010 Nitrogen Dioxide (NO2), and 2010 Sulfur Dioxide (SO2). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA. Whenever EPA promulgates a new or revised NAAQS, the CAA requires the state to make a new SIP submission establishing that the existing SIP meets the various applicable requirements, or revising the SIP to meet those requirements. This type of SIP submission is commonly referred to as an ``infrastructure'' SIP. In this action, EPA is approving the October 24, 2017, submission with respect to: The CAA conflict of interest requirements; and the related conflict of interest infrastructure SIP requirements for the 1997, 2006, and 2012 PM2.5, 2008 8-hour Ozone, 2008 Lead, 2010 NO2, and 2010 SO2 NAAQS. In addition, EPA is approving a portion of ADEM's December 9, 2015, infrastructure SIP submission (as supplemented by the October 24, 2017 submission) related to the conflict of interest requirements for the 2012 PM2.5 NAAQS. This action removes EPA's obligation to promulgate a Federal Implementation Plan (FIP) to address these CAA state board requirements for Alabama.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) for Oklahoma submitted by the State of Oklahoma designee with a letter dated February 14, 2017. The submittal covers updates to the Oklahoma SIP, as contained in annual SIP updates for 2013, 2014, 2015, and 2016, and incorporates the latest changes to EPA regulations. This action will address the revisions submitted to the Oklahoma SIP pertaining to incorporation by reference of federal requirements and emission inventory reporting requirements.

The Environmental Protection Agency (EPA) is announcing a 30- day public comment period associated with release of the draft IRIS Assessment Plan for naphthalene. This document communicates information on the scoping needs identified by EPA program and regional offices and the IRIS Program's initial problem formulation activities. Specifically, the assessment plan outlines the objectives for each assessment and the type of evidence considered most pertinent to address the scoping needs. EPA is releasing this draft IRIS Assessment Plan for public comment at least 30 days in advance of a public science webinar planned on August 23, 2018.

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Colorado on May 26, 2017, addressing regional haze. The revisions include source-specific revisions to the nitrogen oxides (NOX) best available retrofit technology (BART) determination for Craig Station Unit 1 and to the NOX reasonable progress determination for the Nucla Station. Both Craig Station Unit 1 and Nucla Station are owned in part and operated by Tri-State Generation & Transmission Association, Inc. (Tri-State). The EPA is taking this action pursuant to section 110 of the Clean Air Act (CAA).

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving portions of Oklahoma's State Implementation Plan (SIP) submittal, that addresses a CAA requirement that SIPs account for potential interstate transport of air pollution that significantly contributes to nonattainment or interferes with maintenance of the 2012 fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS) in other states. EPA finds that emissions from Oklahoma sources do not contribute significantly to nonattainment in, or interfere with maintenance by, any other state with regard to the 2012 PM2.5 NAAQS.

The Environmental Protection Agency (EPA) is proposing to approve a portion of the state implementation plan (SIP) revision submitted by the District of Columbia (the District) that pertains to the good neighbor and interstate transport requirements of the Clean Air Act (CAA) for the 2008 ozone national ambient air quality standards (NAAQS). The CAA's good neighbor provision requires EPA and states to address the interstate transport of air pollution that affects the ability of other states \1\ to attain and maintain the NAAQS. Specifically, the good neighbor provision requires each state in its SIP to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in another state. The District has submitted a SIP revision that addresses the good neighbor provision for the 2008 ozone NAAQS. In this action, EPA is proposing to approve the District's SIP as having adequate provisions to meet the requirements of the good neighbor provision for the 2008 ozone NAAQS in accordance with section 110 of the CAA.

On June 13, 2018, the Environmental Protection Agency (EPA) proposed an advance notice of proposed rulemaking titled, ``Increasing Consistency and Transparency in Considering Costs and Benefits in Rulemaking Process.'' The EPA is extending the comment period on the proposed rule, which was scheduled to close on July 13, 2018, until August 13, 2018. The EPA is making this change in response to public requests for an extension of the comment period.

The Environmental Protection Agency (EPA) is planning to submit the information collection request (ICR) Facility Ground-Water Monitoring Requirements (Renewal) (EPA ICR No. 0959.16, OMB Control No. 2050-0033) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act (PRA). Before doing so, the EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed extension of the ICR, which is currently approved through October 31, 2018. An Agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.

The Environmental Protection Agency (EPA) is planning to submit the information collection request (ICR), Hazardous Waste Generator Standards (Renewal) (EPA ICR No. 0820.14, OMB Control No. 2050-0035) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act (PRA). Before doing so, the EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed extension of the ICR, which is currently approved through October 31, 2018. An Agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.

The Environmental Protection Agency (EPA) is approving two state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions pertain to base year emission inventories for the Lebanon County and Delaware County nonattainment areas for the 2012 annual fine particulate national ambient air quality standard (NAAQS). The Clean Air Act (CAA) requires states to submit a comprehensive, accurate and current inventory of actual emissions from all sources of direct and secondary ambient fine particulate matter less than 2.5 microns in diameter (PM2.5) for all PM2.5 nonattainment areas. EPA is approving these revisions in accordance with the requirements under Title I of the CAA.

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Yolo-Solano Air Quality Management District (YSAQMD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns the District's negative declarations for several volatile organic compound (VOC) source categories included in its Reasonably Available Control Technology (RACT) State Implementation Plan Analysis. We are approving these negative declarations under the Clean Air Act (CAA or ``the Act'').

The Environmental Protection Agency (EPA) is taking final action to extend the period during which certain electronic reports required by the Mercury and Air Toxics Standards (MATS) may be submitted as portable document format (PDF) files using the Emissions Collection and Monitoring Plan System (ECMPS) Client Tool. This action will extend the end date of that period from June 30, 2018, to July 1, 2020. This extension is necessary because the electronic reporting system that owners or operators of affected MATS sources will be required to use when PDF filing is no longer allowed will not be available by June 30, 2018. This extension does not alter the responsibility of owners or operators of affected MATS sources to comply with the applicable MATS and report their compliance information to the appropriate authority. In addition, this extension ensures that the compliance information can be submitted in a timely manner and made available to the public. Finally, this rule is effective on July 1, 2018, to provide the regulated community a continuous and viable vehicle to submit compliance reports.

Addressing childhood lead exposure is a priority for EPA. As part of EPA's efforts to reduce childhood lead exposure, EPA evaluated the current dust-lead hazard standards (DLHS) and the definition of lead-based paint (LBP). Based on this evaluation, EPA is proposing to lower the DLHS from 40 [mu]g/ft\2\ and 250 [mu]g/ft\2\ to 10 [mu]g/ ft\2\ and 100 [mu]g/ft\2\ on floors and window sills, respectively. EPA is proposing no changes to the current definition of LBP due to insufficient information to support such a change.
