Description
Inspect wastewater, stormwater, and industrial discharge sources to prevent water pollution, enforce Clean Water Act and related state and local regulations, and protect public health and aquatic resources.
- • Participate in developing spill prevention, SSO reduction, and illicit discharge elimination programs, and recommend corrective actions.
- • Maintain and calibrate sampling, monitoring, and safety equipment, and keep vehicles and work sites in good order.
- • Conduct studies on wastewater and stormwater management issues to assess problem magnitude, tracing methods, treatment alternatives, and costs.
- • Respond to public and customer inquiries about sewer service charges, surcharges, and capacity fees, or refer them to supervisors.
- • Prepare data to calculate sewer service charges, industrial surcharges, and capacity fees.
- • Determine the nature of water quality violations, issue notices of violation, and participate in enforcement hearings as needed.
- • Examine NPDES, pretreatment, and stormwater permits, applications, and records to verify compliance.
- • Prepare, organize, and maintain inspection, sampling, and enforcement records.
- • Interview operators, industrial users, and complainants to document suspected violations and obtain evidence.
- • Prepare written, oral, tabular, and graphic reports, including chain-of-custody and enforcement documentation.
- • Monitor corrective actions and review self-monitoring, DMRs, and compliance reports after violations are found.
- • Investigate complaints about illegal discharges, illicit connections, SSOs, construction runoff, or illegal dumping.
- • Inspect wastewater treatment plants, pretreatment systems, pump stations, collection systems, and stormwater BMPs for regulatory conformance.
- • Inform facility representatives and the public of water pollution control requirements and inspection findings, and explain corrective measures.
- • Determine sampling locations and methods, and collect surface water, stormwater, groundwater, or wastewater samples using proper containers and preservation.
- • Verify that hazardous chemicals and wastes are handled, stored, and disposed of to prevent discharges to waters or sewers.
- • Research and stay current on Clean Water Act, NPDES, pretreatment, MS4, and related state and local regulations.
- • Prioritize sites and complaint reports for investigation, and coordinate compliance and enforcement with other agencies.
- • Observe and record field conditions, including flow rates and water quality parameters such as pH, DO, turbidity, and chlorine residual.
- • Follow and enforce safety procedures, including confined space entry, traffic control, and PPE requirements.
- • Review and evaluate industrial user permits, slug control plans, and stormwater pollution prevention plans.
- • Inform health professionals, property owners, and the public about risks from contaminated water, sewage, and runoff.
- • Analyze and implement requirements to maintain approved pretreatment, pollution prevention, IDDE, and stormwater programs.
- • Perform field and laboratory tests on collected samples, such as pH, TSS, BOD/COD, nutrients, and metals.
- • Review and evaluate applications for wastewater discharge, pretreatment, and stormwater permits.
- • Perform calculations for flow, loadings, alternative limits, and wastewater strength classifications, and prepare recommendations and documentation.
