Western States Wholesale Inc DBA Patio Industries is a cement plant located at 1600 E Francis in Ontario, San Bernardino County, California. The facility operates under NAICS code 327310, which covers cement manufacturing. As a cement plant, it is part of the industrial utilities sector that produces cement for construction and infrastructure projects. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), which enforces multi-media environmental regulations including the Clean Air Act (CAA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Toxics Release Inventory (TRI) Section 313 reporting. California also has stringent state-level air quality regulations through the California Air Resources Board (CARB) and local air districts such as the South Coast Air Quality Management District (SCAQMD). Cement plants are subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) and New Source Performance Standards (NSPS). Cement production is energy-intensive and generates significant CO2 emissions from calcination and fuel combustion. The plant's location in Ontario, within the Inland Empire region, places it in an area with growing urban development and associated demand for construction materials. The facility's operational status indicates ongoing contribution to local infrastructure, while its environmental footprint is managed through federal and state permits.

Cement plants are significant sources of air pollutants including particulate matter, nitrogen oxides, sulfur dioxide, and carbon dioxide. The facility's location in San Bernardino County, part of the South Coast Air Basin, is subject to strict air quality management due to non-attainment for ozone and particulate matter. Proximity to residential areas in Ontario may raise community concerns about dust and emissions. Water usage for cooling and process needs, as well as stormwater runoff, are regulated under the Clean Water Act. The plant's operations are also subject to hazardous waste management under RCRA.
