Environmental Protection Agency June 6, 2019 – Federal Register Recent Federal Regulation Documents

The Director of the Water Division, EPA Region 10, is proposing to reissue two aquaculture National Pollutant Discharge Elimination System (NPDES) General Permits; Aquaculture Facilities in Idaho Excluding Facilities Discharging into the Upper Snake-Rock Subbasin, and Aquaculture Facilities Located in Indian Country in Idaho. As proposed, the General Permits will authorize discharges of wastewater from cold water and warm water Concentrated Aquatic Animal Production facilities (also referred to as CAAPs or ``hatcheries''). The permits will largely replace and combine the NPDES General Permit for Cold Water Aquaculture Facilities in Idaho (not subject to Wasteload Allocations) (IDG131000) and the NPDES General Permit for Aquaculture Facilities in Idaho (subject to Wasteload Allocations) (IDG130000) but will exclude facilities discharging within the Upper Snake-Rock Subbasin. The EPA is not taking action on coverage for facilities that discharge within the Upper Snake-Rock Subbasin under IDG130000 at this time; those facilities with coverage will remain covered under IDG130000. Coverage for facilities under IDG130000 that are not within the Upper Snake-Rock Subbasin will be terminated once coverage under IDG131000 or IDG133000 is available. In addition, with this reissuance, the EPA is separating out discharges from aquaculture facilities located in Indian County in Idaho under a separate General Permit number (IDG133000). This will facilitate the transfer of IDG131000 to the State of Idaho in 2020 as part of the phased implementation of Idaho's administration of the NPDES Program. EPA will remain the permitting authority for IDG133000.

Whenever a new or revised National Ambient Air Quality Standard (NAAQS) is promulgated, the Clean Air Act (CAA) requires states to submit a plan for the implementation, maintenance, and enforcement of the standard, commonly referred to as infrastructure requirements. The Environmental Protection Agency (EPA) is approving the Oregon Department of Environmental Quality's (ODEQ) State Implementation Plan (SIP), submitted on September 25, 2018, as meeting infrastructure requirements for the 2015 ozone NAAQS. In addition, the EPA is approving the addition of an Oregon Administrative Rule to the SIP, submitted as part of the Cleaner Air Oregon SIP submission on December 11, 2018. This rule identifies the November 2018 edition of the Code of Federal Regulations (CFR) as the CFR version referred to throughout the state's rule.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving revisions to the Texas State Implementation Plan (SIP) submitted by the Texas Commission on Environmental Quality. The revisions remove rules from the Texas SIP that address vehicle anti-tampering requirements and the Low Income Repair Assistance Program for certain participating counties.
