Overview
Ash Grove Cement - Leamington Utah is an operational cement plant in Nephi, Juab County, Utah. It operates under US EPA regulations including CAA, CWA, and RCRA.
Ash Grove Cement - Leamington Utah is a cement manufacturing facility located approximately 6 miles east of Leamington, Utah, near Nephi in Juab County. The plant is operational and classified under NAICS code 327310 (Cement Manufacturing). As a cement plant, it is a significant industrial facility in the region, contributing to local construction and infrastructure supply chains. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), which enforces multi-media environmental laws including the Clean Air Act (CAA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Toxics Release Inventory (TRI) Section 313 reporting. Cement plants are subject to specific emissions standards for particulate matter, nitrogen oxides, sulfur dioxide, and hazardous air pollutants under the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Portland Cement Manufacturing industry. Cement production is energy-intensive and involves high-temperature kiln processes that can generate significant air emissions. The plant's location in rural Utah, away from major urban centers, may reduce direct community exposure, but regional air quality and water use remain important environmental considerations. Ash Grove Cement is one of the largest cement producers in the United States, and this facility plays a role in supplying cement for construction projects in the Intermountain West.
Environmental context
Cement plants are inherently pollution-intensive due to the calcination of limestone and combustion of fossil fuels, releasing CO2, NOx, SO2, and particulate matter. The facility's location in Juab County, Utah, is characterized by arid climate and sparse population, which may moderate local exposure but does not eliminate regional air quality impacts. Water use for cooling and dust suppression, as well as potential groundwater contamination from raw material storage, are typical concerns. The plant must comply with EPA's National Ambient Air Quality Standards (NAAQS) and state implementation plans.
