CWA 316(b) Technology Evaluations

Since 2003, Alden has provided §316(b) assessments for over 100 facilities affected by the EPA's Phase II Rule. Alden is dedicated to leading the way in further developments of intake technologies.






As the Rule was being developed, Alden was selected by EPA as the recognized expert in the field of alternative fish protection technologies to participate at public meetings. Alden's expertise is recognized and used by both UWAG and EPRI on behalf of the industry for issues related to §316(b) requirements. Alden’s Team is comprised of engineers, fisheries scientists, and modeling personnel.

Our multidisciplinary approach combines expertise in intake design and operational engineering, biology, economics, hydraulics and hydrology, and environmental restoration.

Alden’s philosophy is simple. We use a sensible approach that minimizes compliance costs as well as the costs of studies that may be required to achieve compliance while maximizing benefits. We develop flexible and cost-effective technology, restoration, and/or flow reduction alternatives for achieving compliance.

Our approach includes:

  • Evaluating site configurations to determine the most cost-effective arrangement for alternatives
  • Assessing hydraulic and environmental conditions (debris, sediment, ice, etc.) that affect installation and effectiveness of each alternative
  • Addressing O&M concerns (debris removal and equipment maintenance)
  • Specifying construction techniques
  • Considering existing unit and equipment operation and outages necessary for construction activities and equipment replacement
  • Forecasting construction schedules
  • Identifying capital and O&M costs and economic penalties
  • Incorporating operational testing and biological monitoring features

This approach provides our clients with adequate information to make informed strategic decisions to pursue preferred compliance alternatives.
