NPDES Permit Negotiation & TMDL Support

TMDL Implementation Plans for Cocolalla Lake and Hoodoo Creek  | Idaho, US

Each day, comprehensive stormwater planning, management and design solutions by our engineering professionals benefit watershed areas with diverse field and administrative conditions. Hydrologists and drainage experts at our offices provide planning, preliminary engineering and design services that develop effective, applicable solutions for stormwater problems.

Our technical expertise serves diverse areas ranging from coastal plains to mountainous terrain, from major metropolitan areas to agricultural watersheds, and existing drainage networks to developing suburban areas. Technical experts prepare detailed engineering designs for metropolitan detention/retention basins, piped drainage systems, open channels, pumping stations and other support facilities.

A number of regulatory driven programs such as Total Maximum Daily Loads (TMDL), National Pollutant Discharge Elimination System (NPDES) and the Clean Water Act (CWA) limit pollution discharged into a body of water. State and regional agencies are responsible for ensuring that lakes, rivers and streams remain suitable for recreation. When water bodies fall below these standards, they are subject to oversight from the US EPA and third party lawsuits. Other entities discharging into these water bodies are then regulated to improve their discharges, including storm water, sanitary wastewater or industrial discharges.

We provide the tools clients need to operate successfully in such a highly regulated environment. Our project managers have diverse backgrounds in watershed issues, non-point source loading and point source design. We work with all stakeholders to determine the limiting factors of the water bodies, propose solutions, and prepare the necessary modeling and technical work to achieve the desired goals.

Our clients rely on our balanced approach to solving water quality problems. Our teams of planners, hydrologists, scientists, economists and engineers work together to solve problems involving source reduction, and in-stream and process improvements. Our experts are strong advocates for the client's position.
