Environmental Protection Agency March 13, 2006 – Federal Register Recent Federal Regulation Documents

EPA is proposing to revise the EPA Acquisition Regulation (EPAAR) Subparts 1532 and 1552 to implement a procedure for simplified acquisition procedures financing. This proposed EPAAR revision will add a prescription and clause for contracting officers to use when approving advance or interim payments on simplified acquisitions. The proposed prescription and clause apply to commercial item orders at or below the simplified acquisition threshold. This action revises the EPAAR, but does not impose any new requirements on Agency contractors. The procedure will allow contractors to invoice for advance and interim payments in accordance with standard commercial practices when authorized by the contracting officer and identified in the clause payment schedule.

EPA is announcing the partial approval and partial disapproval of revisions to the Restriction of Emission of Sulfur Compounds rule in the Missouri State Implementation Plan (SIP). This Missouri rule establishes general requirements for emissions of sulfur compounds from various source categories and establishes specific emissions requirements for certain named sources. EPA is approving most of the revisions to the rule because the changes involve clarifications, updates, and other improvements to the current rule. This action does not include a portion of the rule that regulates ambient concentrations of sulfur compounds, because this provision is not in the current SIP, and EPA does not directly enforce Missouri's Air Quality Standards. EPA is disapproving Missouri's request to include in the SIP a revision to two source-specific references because the state has not demonstrated that the revisions are protective of the short-term SO2 National Ambient Air Quality Standard (NAAQS).
