Environmental Protection Agency September 10, 2021 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency has submitted an information collection request (ICR), ``NSPS for Lime Manufacturing (EPA ICR Number 1167.13, OMB Control Number 2060-0063), to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through December 31, 2021. Public comments were previously requested, via the Federal Register, on February 8, 2021 during a 60-day comment period. This notice allows for an additional 30 days for public comments. A fuller description of the ICR is given below, including its estimated burden and cost to the public. An agency may neither conduct nor sponsor, and a person is not required to respond to, a collection of information unless it displays a currently-valid OMB control number.

The Environmental Protection Agency (EPA) is finalizing a limited approval and limited disapproval of a revision to the Mojave Desert Air Quality Management District's (MDAQMD or District) portion of the California State Implementation Plan (SIP). This revision concerns oxides of nitrogen (NOX) emissions from stationary internal combustion engines. Under the authority of the Clean Air Act (CAA or the ``Act''), this action approves a local rule that regulates these emission sources into the federally-enforceable SIP, thereby strengthening the SIP, while identifying deficiencies with the rule that must be corrected by the MDAQMD in order for the EPA to grant full approval of the rule.

The Environmental Protection Agency (EPA) (also, ``the Agency'' or ``we'' in this preamble) is taking final action to finalize technical amendments to an existing exclusion from the list of federal hazardous waste (delisting) issued to the United States Department of Energy (Energy) under the Resource Conservation and Recovery Act. These modifications address changes to the 200-Area Effluent Treatment System associated with the delisting necessary to accept liquid effluents expected to be generated from vitrification of certain low-activity mixed wastes at the Hanford Federal Facility, or Hanford Site, in Richland, Washington.
