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
