Approval and Promulgation of Implementation Plans; Oregon; Interstate Transport of Pollution; Significant Contribution to Nonattainment and Interference With Maintenance Requirements 

EPA is proposing to approve a portion of the State Implementation Plan (SIP) revision submitted by the State of Oregon for the purpose of addressing the interstate transport provisions of Clean Air Act (CAA) section 110(a)(2)(D)(i)(I) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (PM2.5) NAAQS. Section 110(a)(2)(D)(i) of the CAA requires that each State have adequate provisions to prohibit air emissions from adversely affecting air quality in other States through interstate transport. EPA is proposing to approve Oregon’s SIP revision for the 1997 8-hour ozone and 1997 PM2.5 NAAQS as meeting the requirements of CAA section 110(a)(2)(D)(i)(I) to prohibit emissions that will contribute significantly to nonattainment of the these standards in any other State and to prohibit emissions that will
interfere with maintenance of these standards by any other State.

DATES: Written comments must be received on or before May 9, 2011.

Supplemental proposed rule for NESHAP: Mercury Emissions From Mercury Cell Chlor-Alkali Plants

Thursday, April 7th, 2011

 This action proposes amendments to the national emission standards for hazardous air pollutants (NESHAP) for mercury emissions from mercury cell chlor-alkali plants (Mercury Cell NESHAP). On June 11, 2008, EPA proposed amendments to this NESHAP in response to a petition for reconsideration filed by the Natural Resources Defense Council (NRDC).  This action is a supplement to the June 11, 2008, proposal. Specifically, this action proposes two options for amending the NESHAP for mercury emissions from mercury cell chlor-alkali plants. The first option would require the elimination of mercury emissions and thus encourage the conversion to non-mercury technology. The second option would require the measures proposed in 2008. These measures, which included significant improvements in the work practices to reduce fugitive emissions from the cell room, would result in near-zero levels of mercury emissions while still allowing the mercury cell facilities to continue to operate. We are specifically requesting comment on which of these options is more appropriate, and may finalize either option or a combination of elements from them. In addition, this action proposes several amendments that would apply regardless of which option we select. These proposed amendments are provisions of the existing NESHAP that would apply to periods of startup, shutdown, and malfunction (SSM), and corrections to compliance errors in the currently effective rule.
