Environmental Protection Agency August 28, 2020 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the Navajo Nation revised its approved Public Water System Supervision (PWSS) Program under the federal Safe Drinking Water Act (SDWA) by adopting the Arsenic Rule, Consumer Confidence Report (CCR) Rule, Filter Backwash Recycling Rule (FBRR), Lead and Copper RuleMinor Revisions (LCR-MR), and Stage 1 Disinfectants and Disinfection Byproducts (DBP) Rule. The Environmental Protection Agency (EPA) has determined that these revisions by the Navajo Nation are no less stringent than the corresponding Federal regulations and otherwise meet applicable SDWA primacy requirements. Therefore, the EPA intends to approve these revisions to the Navajo Nation's PWSS Program.

EPA has received applications to register pesticide products containing active ingredients not included in any currently registered pesticide products. Pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is hereby providing notice of receipt and opportunity to comment on these applications.

The Environmental Protection Agency (EPA) is providing notice of the availability of data on the administration of the assurance provisions of the Cross-State Air Pollution Rule (CSAPR) trading programs for the control periods in 2019. Total emissions of nitrogen oxides (NOX) reported by Mississippi units participating in the CSAPR NOX Ozone Season Group 2 Trading Program during the 2019 control period exceeded the state's assurance level under the program. Data demonstrating the exceedance and EPA's final calculations of the amounts of additional allowances that the owners and operators of certain Mississippi units must surrender have been posted in a spreadsheet on EPA's website.

On April 17, 2015, the Environmental Protection Agency (EPA or the Agency) promulgated national minimum criteria for existing and new coal combustion residuals (CCR) landfills and existing and new CCR surface impoundments. On August 21, 2018, the U.S. Court of Appeals for the D.C. Circuit issued its opinion in the case of Utility Solid Waste Activities Group v. EPA, 901 F.3d 414 (per curiam) (USWAG). This rule finalizes regulations, proposed on December 2, 2019, to implement the court's vacatur of the 2015 provisions. The court vacated provisions that allowed unlined impoundments to continue receiving coal ash unless they leak, and classified ``clay-lined'' impoundments as lined, thereby allowing such units to operate indefinitely. In addition, EPA is establishing a revised date by which unlined surface impoundments must cease receiving waste and initiate closure, following its reconsideration of those dates in light of the USWAG decision. Lastly, EPA is finalizing amendments proposed on August 14, 2019, to the requirements for the annual groundwater monitoring and corrective action report and the requirements for the publicly accessible CCR internet sites.

Pursuant to the Resource Conservation and Recovery Act (RCRA or Act), the Environmental Protection Agency (EPA) is proposing to approve revisions to the State of New Mexico's Underground Storage Tank (UST) program submitted by the State. This proposed action is based on EPA's determination that these revisions satisfy all requirements needed for program approval. This proposal action also proposes to codify EPA's approval of New Mexico's state program and to incorporate by reference those provisions of the State regulations that we have determined meet the requirements for approval. The provisions will be subject to EPA's inspection and enforcement authorities under sections 9005 and 9006 of RCRA subtitle I and other applicable statutory and regulatory provisions.
