The Minnesota Pollution Control Agency (MPCA) is hosting a live webinar on pretreatment, Wednesday January 19, 1:00-2:30 PM CST. 1.5 professional development hours (pdh) are available for attending this webinar.

This webinar will provide information on the importance and value of pretreatment, examples of how pretreatment is being implemented, and common concerns with pretreatment. The tentative agenda is as follows.


While the benefits of pretreatment are well understood, we continue to see ineffective pretreatment as a result of poor design or construction, inadequate maintenance, incorrect choice of practice, inadequate sizing, and so forth. The objectives for this webinar are to reiterate the role and importance of pretreatment, provide examples of good and recommended practices, and discuss some common concerns with pretreatment implementation.


  • Introduction to and importance of pretreatment: Dr. John Chapman, Department of Bioproducts and Biosystems Engineering, University of Minnesota
  • Examples of selection, implementation and efficient maintenance of pretreatment practices
    • Noah Czech, Stormwater Compliance Specialist, City of St. Cloud, Minnesota
    • Mike Isensee, CPESC, Administrator, Carnelian Marine St. Croix Watershed District
  • Observation of pretreatment practices - the good, bad, and ugly
    • Chris French, Regulatory Manager, Bio Clean Environmental
  • Overview of what is in the Minnesota Stormwater Manual (Mike Trojan, MPCA)
  • Q&A
