Questions Asked in NPDES and other Regulatory Compliance Interview
Q 1. Explain the key requirements of an NPDES permit.
An NPDES (National Pollutant Discharge Elimination System) permit is a legal document issued by the Environmental Protection Agency (EPA) or a delegated state agency, authorizing the discharge of pollutants into waters of the United States. The key requirements vary depending on the specific permit, but generally include:
- Effluent limitations: These specify the maximum amount of each pollutant that can be discharged from a facility, often expressed in pounds per day or milligrams per liter. For example, a permit might limit the discharge of total suspended solids (TSS) to 100 mg/L.
- Monitoring and reporting requirements: Permittees must regularly sample and analyze their discharge to ensure they meet the effluent limitations. They then submit these results in regular reports to the regulatory agency. This might involve collecting samples weekly or monthly, depending on the nature of the discharge and the permit requirements.
- Pretreatment standards (for indirect dischargers): Industries discharging wastewater to a publicly owned treatment works (POTW) must comply with pretreatment standards to protect the POTW’s treatment process.
- Specific technology-based requirements: The permit may mandate the use of specific pollution control technologies, such as a clarifier or a filter, to reduce pollutant levels.
- Spill prevention, control, and countermeasure (SPCC) plan: For facilities that handle significant amounts of oil, an SPCC plan is often required to prevent and mitigate oil spills.
- Best Management Practices (BMPs): These are methods and practices designed to minimize pollution at the source. Examples include erosion and sediment control measures during construction or implementation of stormwater management techniques.
Think of an NPDES permit as a contract between the permittee and the regulatory agency. The permittee agrees to meet specific conditions, and the agency agrees to allow the discharge under those conditions.
Q 2. Describe the process of obtaining an NPDES permit.
The process of obtaining an NPDES permit generally involves several steps:
- Application submission: The facility owner or operator must complete a detailed application that provides information about the facility, its discharge, and its pollution control measures.
