The 卡森城 ECA manages a Pretreatment Program, which is federally mandated (Under the Clean 水 Act) and EPA approved, and designed to protect the city’s residents and environment from toxic wastewater discharged from commercial sources.

To control commercial wastewater discharges in 卡森城, the ECA reviews all commercial building plans for the required plumbing and pretreatment systems and asbestos removal, issues wastewater discharge permits, and routinely inspects hundreds of businesses to determine if they are in compliance with the permit conditions, as well as their potential for illegal wastewater discharges.

The ECA enforces these permits, and non-compliance can result in criminal penalties. Authority is provided in 卡森市市政法规 Chapter 12.06, through an EPA Region IX approved Enforcement Response Plan, and Enforcement Response Guide (ERP/ERG).

The ECA also monitors businesses that store products with the potential to contaminate soil, 雨水和地下水, and samples two manholes twice a week that receive the majority of flow from most of the businesses located in the Industrial Park.

This program is similar to the Pretreatment Program, with a focus on monitoring businesses utilizing septic tank systems. The ECA monitors these businesses’ systems and the business owner must fix any contamination using Nevada Division of Environmental Protection standards.

The ECA also inspects businesses that generate a non-reusable by-product that form a hazardous waste. 如果ECA发现危险废物, it works with the Nevada Division of Environmental Protection to ensure the waste is properly transported and disposed following Resource Conservation and Recovery Act (RCRA) regulations.
