Environmental Protection Agency July 11, 2019 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) Region 7 is issuing a Notice of Intent to Delete the Electro-Coatings, Inc. Superfund Site (Site) located at 911 Shaver, Cedar Rapids, Iowa, 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 (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the State of Iowa, through the Iowa Department of Natural Resources (IDNR), have determined that all required and appropriate response actions at the Electro-Coatings under CERCLA have been completed. However, this deletion does not preclude future actions under Superfund.

The Environmental Protection Agency (EPA) is approving Arizona's Regional Haze Progress Report (``Progress Report'' or ``Report''), submitted on November 12, 2015, as a revision to its state implementation plan (SIP). This SIP revision addresses requirements of the Clean Air Act (CAA) and the EPA's rules that require states to submit periodic reports describing progress toward reasonable progress goals (RPGs) established for regional haze and a determination of adequacy of the state's existing regional haze plan. The EPA is approving the Report on the basis that it addresses the progress report and adequacy determination requirements for the first implementation period for regional haze.

Notification is hereby given in accordance with the provision of section 1413 of the Safe Drinking Water Act, as amended, and the requirements governing the National Primary Drinking Water Regulations Implementation that the State of Delaware is revising its approved Public Water System Supervision Program. The State has adopted several regulations which will provide for better public health protection by reducing exposure to potential contaminants in drinking water. EPA has determined that these revisions are no less stringent than the corresponding Federal regulations. EPA is taking action to tentatively approve these program revisions.

The Environmental Protection Agency (EPA) is proposing to conditionally approve a revision to the State of Nevada's State Implementation Plan (SIP) for Clark County. The revision consists of an update to certain elements of the maintenance plan for the Clark County air quality planning area for the 1997 8-hour ozone national ambient air quality standards (NAAQS or ``standards''), including the emissions inventories, maintenance demonstration, and motor vehicle emissions budgets. The EPA is proposing to conditionally approve the SIP revision because the Clark County ozone SIP, as revised, continues to provide for maintenance of the 1997 ozone NAAQS and, upon fulfillment of certain commitments, will not interfere with attainment or reasonable further progress of the other NAAQS, and the budgets meet the applicable transportation conformity requirements. The proposed approval is conditional because it is based on commitments to submit a SIP revision to reduce the safety margin allocations for the budgets within one year of final conditional approval.

The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the District of Columbia (the District). The District's SIP revision satisfies the volatile organic compound (VOC) reasonably available control technology (RACT) requirements under the 2008 8-hour ozone national ambient air quality standard (NAAQS). The District will address RACT for nitrogen oxides (NOX) in a separate SIP submission. The District's RACT submittal for the 2008 ozone NAAQS includes certification that for certain major sources, previously adopted VOC RACT controls in the District's SIP that were approved by EPA under the 1979 1-hour and 1997 8-hour ozone NAAQS are based on the currently available technically and economically feasible controls, and continue to represent RACT for implementation of the 2008 8-hour ozone NAAQS; a listing of the Control Techniques Guidelines (CTGs) already adopted into the District's SIP, and a listing of those categories of sources subject to CTGs which do not exist in the District and the location of prior negative declarations previously submitted and approved by EPA. The District's SIP submittal also includes an update to the 2002 Mobile Equipment Repair and Refinishing (MERR) rule to incorporate the Ozone Transport Commission's (OTC) 2009 Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations regulations (MVMERR) rule adopted by the District in 2016. EPA is addressing the 2009 MVMERR rule in a separate rulemaking action as it is not related to the 2008 VOC RACT SIP revision and does not impact EPA's proposed approval. This action is being taken under the Clean Air Act (CAA).
