For more information and guidance materials on how to collect a stormwater sample, see Step 10: Sample/monitor your stormwater.

Monitoring/Sampling Workshops:

More U of M Monitoring Training Workshops are in the works. If your company/organization would like training or can offer space to host future trainings, please contact the Erosion and Stormwater Management Certification Program.

University of Minnesota Industrial Stormwater Sampling and Monitoring Training Opportunities:

• June 21, 2012 (tentative): U of M training on "Industrial Stormwater Response to Benchmark Exceedance" workshop held at the Chanhassen Rec Center. Registration will begin at 10:00 a.m., and the class will conclude at 2:30 p.m. The registration fee is $75. For more information or to register, download the registration form.

Sand, Gravel and Concrete Activity owners:

If your facility mines construction sand and gravel; quarries limestone, granite or dimension stone; operates hot mix asphalt production areas and/or has concrete manufacturing/recycling activities, please visit the Nonmetallic Mining and Associated Activities webpage to see if this permit is the right fit for you.  The permit allows facilities to gain stormwater and wastewater coverage for multiple sites and activities under one permit.
