FREDERICK ASPHALT CO/ESSROC SITE - Cement Plant in Frederick, Maryland, USA

FREDERICK ASPHALT CO/ESSROC SITE is a cement plant located at 4120 Buckeystown Pike in Frederick, Maryland, United States. The facility is operational and classified under NAICS codes 212312 (crushed and broken limestone mining), 324121 (asphalt paving mixtures and blocks), 327310 (cement manufacturing), and 493190 (other warehousing and storage), indicating a multi-faceted industrial operation. As a cement plant in the United States, this facility operates under a comprehensive regulatory framework administered by the US Environmental Protection Agency (EPA). Key regulations include the Clean Air Act (CAA) for emissions of particulate matter, nitrogen oxides, and sulfur dioxide; the Clean Water Act (CWA) for process wastewater and stormwater discharges; the Resource Conservation and Recovery Act (RCRA) for hazardous waste management; and the Toxics Release Inventory (TRI) Section 313 for annual reporting of toxic chemical releases. The plant likely uses dry or wet kiln processes typical of cement manufacturing, with potential for energy recovery from waste fuels. The facility's location in Frederick County places it within a region with a mix of industrial and residential areas. Cement plants are significant sources of greenhouse gas emissions and air pollutants, and their proximity to communities requires careful environmental management. The plant's operational status and multi-NAICS classification suggest it plays a role in local construction materials supply, including asphalt and cement products.

Cement plants are inherently pollution-intensive, with primary emissions including particulate matter, nitrogen oxides, sulfur dioxide, carbon dioxide, and heavy metals from clinker production. The facility's location in Frederick, Maryland, places it in a region with moderate population density, requiring compliance with local air quality standards. Community proximity may raise concerns about dust and noise, but regulatory oversight under the Clean Air Act and state permits aims to mitigate impacts. The plant's multi-NAICS operations also involve asphalt production, which can emit volatile organic compounds and hazardous air pollutants.
