FAQ
Questions fréquemment posées
What is an NPDES permit?
The National Pollutant Discharge Elimination System (NPDES) permit is the primary mechanism under the US Clean Water Act for regulating direct discharges of pollutants to waters of the United States. NPDES permits set effluent limits based on: (1) Technology-based standards (Best Available Technology), and (2) Water quality-based standards (site-specific limits to protect receiving waters). Permits are issued by EPA or authorized state agencies and typically require monthly Discharge Monitoring Reports (DMRs). BioTerraVa provides NPDES permit application support, compliance monitoring, and treatment design services.
How do EPA effluent limitation guidelines work?
EPA effluent limitation guidelines (ELGs) are technology-based regulations that set national standards for specific industries. ELGs are based on the performance of the Best Available Technology (BAT) economically achievable. They apply to both direct dischargers (with NPDES permits) and indirect dischargers (to POTWs). Currently, EPA has ELGs for 59 industrial categories including: metal finishing, pulp and paper, petroleum refining, and food processing. BioTerraVa ensures treatment designs meet or exceed applicable ELGs with compliance margin.
What are the penalties for Clean Water Act violations?
Clean Water Act violations carry civil penalties up to $66,086 per day per violation (adjusted annually for inflation). Criminal penalties for knowing violations can reach $50,000 per day and 3 years imprisonment. Additionally, citizen suits under the Clean Water Act can add further liability and require payment of plaintiffs' legal fees. The best defense against penalties is proactive compliance monitoring, early detection of issues, and immediate corrective action. BioTerraVa designs compliance programs that minimize violation risk.
