Policy White Papers
The UDAQ is examining several potential new administrative rules to reduce ozone precursor emissions. Below is a selection of white papers and fact sheets that overview some of these potential rules. These documents are all in draft form, and the UDAQ welcomes feedback and insights on any and all aspects of these emission reduction strategies and the associated economic and technical feasibility analyses.

Modeling
The objective of this project is to create a verified list of facilities and inventory of air emissions that comply with the criteria set forth in Maricopa County Rule 327 for commercial composting processes. Specifically, at DAQ, we aim to identify qualifying sources in the Northern Wasatch Front Ozone Nonattainment Area (NWFNAA) and assess the emissions from these facilities. This will include facilities operating in Utah, Salt Lake, Tooele, Weber and Davis counties. The air emissions data to be collected include volatile organic compounds (VOCs) and ammonia, which contribute to fine particulate matter (PM2.5), as well as nitrogen oxides (NOx).
This project seeks to understand the potential emissions reductions that could result from implementing a Rule in the NWFNAA similar to Maricopa County’s Rule 327. By identifying sources and quantifying their emissions, we can gain insights into:
- The impact of a Rule on reducing ozone formation
- The cost effectiveness of the rule within our airshed
- The contribution of emissions reductions to meet the Reasonable Further Progress (RFP) goals required for our Ozone State Implementation Plan (SIP) by the Clean Air Act
In an effort to identify potential emission reduction strategies to reduce emissions of Volatile Organic Compounds within the Northern Wasatch Front nonattainment area, the Utah Division of Air Quality is examining potential revisions to Utah Administrative Rule R307-327; Ozone Nonattainment and Maintenance Areas: Petroleum Liquid Storage. The documents contained on this page include a white paper examining the technical and economic feasibility of some potential strategies, as well as a draft of potential rule language associated with these policies.
All documents contained here are in draft form and are intended to serve only as an overview of potential policies to reduce ozone precursor emissions, as well as the associated financial and technical feasibility. The Utah Division of Air Quality welcomes feedback from stakeholders on any and all aspects of these documents, and encourages further collaboration from any interested parties on the included policies.
