Environmental Protection Agency June 26, 2018 – Federal Register Recent Federal Regulation Documents

This regulation establishes tolerances for residues of fluroxypyr in or on teff forage, teff grain, teff hay, and teff straw. Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).

Environmental Protection Agency (EPA) Region 7 is issuing a Notice of Intent to Delete 101 residential parcels of the Omaha Lead Superfund site located in Omaha, Nebraska, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the state of Nebraska, through the Nebraska Department of Environmental Quality, determined that all appropriate response actions under CERCLA were completed at the identified parcels. However, this deletion does not preclude future actions under CERCLA. This partial deletion pertains to 101 residential parcels. The remaining parcels will remain on the NPL and are not being considered for deletion as part of this action.

The U.S. Environmental Protection Agency (EPA), Office of Air Quality Planning and Standards (OAQPS), is soliciting information to facilitate the Clean Air Scientific Advisory Committee's (CASAC) consideration of any adverse public health, welfare, social, economic, or energy effects which may result from various strategies for attainment and maintenance of national ambient air quality standards (NAAQS).

The Environmental Protection Agency (EPA) is taking direct final action to withdraw from EPA regulation and management one designated ocean dredged material disposal site, the Grays Harbor Eight Mile Site, located near the mouth of Grays Harbor, Washington. This action is pursuant to the Marine Protection, Research, and Sanctuaries Act, as amended. The disposal site was designated by the EPA for a specific one-time use in 1990. The Grays Harbor Eight Mile Site fulfilled its intended purpose in 1990 as a single-use disposal site, and monitoring indicates that there will be no unacceptable adverse impacts to the marine environment once the EPA relinquishes management of the site. Five other open-water dredged material disposal sites remain in close proximity to the mouth of Grays Harbor. These sites remain available for use for the disposal of suitable dredged material and are not affected by this withdrawal.

The Environmental Protection Agency (EPA) is announcing a public comment period for the draft document titled, ``Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate MatterEcological Criteria'' (EPA/ 600/R-18/097). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development (ORD) as part of the review of the secondary (welfare- based) National Ambient Air Quality Standards (NAAQS) for oxides of nitrogen, oxides of sulfur, and particulate matter. The Integrated Science Assessment (ISA), in conjunction with additional technical and policy assessments, provides the scientific basis for EPA's decisions on the adequacy of the current NAAQS and the appropriateness of possible alternative standards. On January 28, 2016, EPA released a separate ISA as part of an independent review for the primary (health- based) NAAQS for oxides of nitrogen (EPA/600/R-15/068). In addition, EPA also released a separate ISA to support the primary NAAQS review for oxides of sulfur (EPA/600/R-17/451, December 13, 2017), and is currently reviewing the primary and non-ecological secondary (e.g., visibility, climate, materials damage) NAAQS for particulate matter. EPA is releasing this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public (meeting date and location to be specified in a separate Federal Register notice). This draft document is not final, as described in EPA's information quality guidelines, and it does not represent, and should not be construed to represent, Agency policy or views. When revising the document, EPA will consider any public comments submitted during the public comment period specified in this notice.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing approval of revisions to the Texas State Implementation Plan (SIP) addressing volatile organic compounds (VOC) revised rules and the State's reasonably available control technology (RACT) analyses for VOC and nitrogen oxides (NOX). We are proposing to approve the revised VOC rules as assisting in reaching attainment of the 2008 ozone National Air Quality Ambient Air Quality Standards (NAAQS or the standard) and as meeting the RACT requirements in the Houston- Galveston-Brazoria 2008 8-hour ozone nonattainment area (HGB area). We are also proposing to approve negative declarations for certain VOC source categories subject to RACT in the HGB area. The EPA also is proposing to find that the State's RACT analyses demonstrate that the HGB area meets the VOC and NOX RACT requirements for this standard.

The Environmental Protection Agency (EPA) is taking final action to approve State Implementation Plan (SIP) revisions submitted by the State of South Dakota on October 4, 2017 related to South Dakota's Air Pollution Control Program. The October 4, 2017 submittal revises certain definitions and dates of incorporation by reference and contains new, amended and renumbered rules. In this rulemaking, we are taking final action on all portions of the October 4, 2017 submittal, except for those portions of the submittal which do not belong in the SIP. This action is being taken under section 110 of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the South Carolina State Implementation Plan (SIP). The revision makes a modification to the definition of ``volatile organic compounds'' (VOC). EPA is approving the SIP revision submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (DHEC) on September 5, 2017, because the State has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
