Brandon Steets, P.E.

Brandon Steets is a Senior Principal Engineer based in California with more than 18 years of experience specializing in National Pollutant Discharge Elimination System (NPDES) and Total Maximum Daily Load (TMDL) regulations, water quality modelling and monitoring, pollutant source investigation, and stormwater best management practices (BMP) planning and design.

Brandon frequently serves as technical expert on NPDES-related litigation and enforcement response. He is also a trusted resource to regulators including the California State Water Resources Control Board (SWRCB). For example, Brandon led modeling (e.g., for the Industrial General Permit [IGP] TMDL Amendment) and special studies (e.g., drywell guidance and instream flow criteria modeling) that will form the basis of new statewide regulations or policy.

A subject matter expert on bacteria/pathogen issues, Brandon's specialty includes microbial source tracking (MST). He is a member of the SWRCB's Clean Beaches Task Force, co-editor of the ASCE report Pathogens in Urban Stormwater Systems, and peer reviewer for the journal Water Research. He has published articles in Stormwater magazine and Water Research on topics of bacteria treatment and modeling. He developed new MST guidance for Colorado and New England, performed MST training through a SWRCB webinar series, and led a MST study on Boston Water and Sewer Commission's Illicit Discharge Detection and Elimination (IDDE) program, which was recognized through a 2018 National Association of Clean Water Agencies (NACWA) award.

Brandon is a California Stormwater Quality Association (CASQA)-certified Industrial General Permit (IGP) Trainer of Record (ToR) and Qualified Industrial Stormwater Practitioner (#121). He developed CASQA's statewide guidance manual on non-industrial/background pollutant source demonstration. He managed the Boeing Santa Susana Field Laboratory Biofilter, which won the 2013 CASQA award for outstanding BMP. He advised the National Academy of Sciences regarding industrial stormwater recommendations for U.S. EPA's 2020 Multi-Sector General Permit renewal.

For municipal stormwater clients, Brandon has led modeling in over a dozen watersheds to plan over $6 billion in new green infrastructure and demonstrate compliance with TMDL limits (i.e., Reasonable Assurance Analysis [RAA]). He is also actively involved with the Interstate Technology and Regulatory Council (ITRC) Stormwater BMP Performance Evaluation Team, developing guidance on BMP performance for state regulators nationwide, and he currently supports a new ITRC team on Harmful Algal Blooms.
