Environmental Protection Agency July 26, 2019 – Federal Register Recent Federal Regulation Documents

Pursuant to the Resource Conservation and Recovery Act (RCRA or Act), the Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State of Oregon's Underground Storage Tank (UST) program submitted by the State. The EPA has determined that these revisions satisfy all requirements needed for program approval. This action also codifies the EPA's approval of Oregon's State program and incorporates by reference those provisions of the State's regulations that we have determined meet the requirements for approval. The State's federally-authorized and codified UST program, as revised pursuant to this action, will remain subject to the EPA's inspection and enforcement authorities under Sections 9005 and 9006 of RCRA Subtitle I and other applicable statutory and regulatory provisions.

The Environmental Protection Agency (EPA) is proposing amendments to the General Provisions to the National Emission Standards for Hazardous Air Pollutants (NESHAP). The proposed amendments implement the plain language reading of the ``major source'' and ``area source'' definitions of section 112 of the Clean Air Act (CAA) and provide that a major source can reclassify to area source status at any time by limiting its potential to emit (PTE) hazardous air pollutants (HAP) to below the major source thresholds of 10 tons per year (tpy) of any single HAP or 25 tpy of any combination of HAP. The EPA is proposing that PTE HAP limits must meet the proposed effectiveness criteria of being legally and practicably enforceable. The proposal also clarifies the requirements that apply to sources choosing to reclassify to area source status after the first substantive compliance date of an applicable NESHAP standard. The EPA is proposing electronic notification when a source reclassifies. We are also proposing to revise provisions in specific NESHAP standards that specify the applicability of General Provisions requirements to account for the regulatory provisions we are proposing to add through this rule.
