PM2.5 SIP Development
The PM2.5 State Implementation Plan (SIP) development process is nearing completion. The Utah Air Quality Board adopted the Logan, UT-ID PM2.5 Nonattainment SIP on December 5, 2012. This SIP can be found here. The majority of the rules that are part of the SIP have also been adopted by the Board and have already become effective. A list of all effective Utah Air Quality Rules can be found here. Further work continues for the two remaining Wasatch Front PM2.5 SIPs, and we anticipate that the Board will propose these SIPs for public comment this summer. A list of the proposed rules and their corresponding public comment periods can be found here. The proposed Technical Support Document or TSD, which is the basis for SIP can also be found here. The TSD is not a part of the SIP, but is a companion piece that serves as the technical basis for the decisions made in the SIP. It describes the emissions inventories, modeling, and control strategies.
A short informational video and companion booklet were produced to provide the public with information about the PM2.5 SIP development process.
Information about the proposed SIP and rules, public comment periods, and public hearings will also be published in the State Bulletin
During the SIP and rule comment periods, comments can be submitted in writing at:
Utah Division of Air Quality
PO Box 144820
Salt Lake City, UT 84114-4820
or by email to Mark Berger
The Interactive Data Explorer is available for an in-depth look at the emissions inventory used in the air quality modeling analysis.
