Monroc Inc. (East Plant) - Cement Plant in Murray, Utah, USA

Monroc Inc. (East Plant) is a cement plant situated at 5300 S. State Street in Murray, Salt Lake County, Utah. The facility is operational and classified under NAICS codes 324121 (Portland Cement Manufacturing) and 327310 (Ready-Mix Concrete Manufacturing), reflecting its role in producing cement and concrete products for regional construction and infrastructure. The plant operates within the United States regulatory framework, which includes the Clean Air Act (CAA) for emissions, the Clean Water Act (CWA) for water discharges, and the Resource Conservation and Recovery Act (RCRA) for waste management. As a cement facility, it is subject to EPA's National Emission Standards for Hazardous Air Pollutants (NESHAP) for Portland cement manufacturing, requiring controls on particulate matter, mercury, and other pollutants. The plant's scale is typical for a mid-sized cement operation in the Intermountain West. Cement plants are energy-intensive and significant sources of CO2, NOx, and SO2 emissions. Monroc's East Plant serves the Salt Lake City metropolitan area, contributing to local construction supply chains. Its proximity to urban areas necessitates compliance with state and federal air quality standards, particularly in the non-attainment area for PM2.5 in Salt Lake County.

Located in the Salt Lake Valley, the plant operates in a region with frequent temperature inversions that trap pollutants, exacerbating air quality issues. The area is designated as a non-attainment zone for PM2.5 under the Clean Air Act. Cement production generates particulate matter, nitrogen oxides, and sulfur dioxide, which can contribute to local smog and respiratory concerns. The facility's proximity to residential areas in Murray increases community exposure to industrial emissions, requiring stringent regulatory oversight.
