Herrera’s scientists and engineers have successfully completed a variety of projects relating to NPDES permit compliance including developing policies and procedures consistent with Ecology’s Stormwater Management Manual for Western Washington and the Phase I and II municipal permits; preparing municipal stormwater pollution prevention plans (SWPPPs); performing operation and maintenance (O&M) inspections, source control inspections, IDDE awareness level training, stormwater Best Management Practice (BMP) training, water quality monitoring and analysis training, and spill response training; developing O&M checklists; identifying gaps in Phase II permit compliance; updating stormwater comprehensive plans; performing LID training in association with the Puget Sound Partnership; and performing statewide WSDOT Highway Runoff Manual training in 2006 and 2007. Herrera also has experience with a wide variety of relevant fieldwork including pollutant source tracking studies, outfall surveys, pollutant loading assessments, and stormwater BMP performance evaluations.

This complementary experience in the practical application of municipal procedures, combined with experience training municipal staff on those same procedures, allows us to develop training programs that not only meet basic NPDES permit requirements, but also resonate with staff and increase comprehension and performance. We understand which sections of the Phase II permit are most important (to municipal staff, and to Ecology), as well as most often misunderstood, and can help you incorporate this information into your current programs.
