Approval and Promulgation of Air Quality Implementation Plans; Utah's Emission Inventory Reporting Requirements

EPA is taking direct final action approving State Implementation Plan (SIP) revisions submitted by the State of Utah on September 7, 1999, and December 1, 2003. The revisions add the requirements of EPA's Consolidated Emission Reporting Rule (CERR) to the State's SIP. Utah has submitted four SIPs that relate to today's action on the CERR requirements. The State of Utah submitted a SIP revision on September 20, 1999, which did not make any substantive changes, but adopted a re-organization and renumbering of the air quality regulations. Although EPA is not acting on this particular submittal, EPA is approving and incorporating by reference rules using this new numbering scheme. Approving these rules rather than the earlier version will avoid confusion to the public and will obviate the need for future SIP revisions merely to renumber the SIP. In the remainder of this notice, we will refer to the rules by their current numbers, as reflected in the September 20, 1999 submittal, unless the context dictates otherwise. EPA is acting on the submittal of September 7, 1999, which addresses inventory requirements for emissions from landfills. EPA is approving only the emission inventory requirement for larger landfills, located at Utah Rule R307-221-1 under the State's new numbering system. As emissions from these larger landfills may exceed the emission reporting thresholds addressed in the CERR, Utah must include this information in its emission inventory report to EPA. The remainder of the September 7, 1999 revisions do not affect the State's ability to comply with the CERR; therefore, EPA is not acting on them. The Governor submitted additional revisions to their air quality emission inventory rules on October 23, 2000, which addressed inventory requirements for ammonia emissions. These revisions are contrary to the CERR issued on June 10, 2002 and, therefore, EPA is not acting on the October 23, 2000 SIP. The December 1, 2003 submittal adopted the requirements of the CER
