Construction Site Runoff Control

According to the EPA Fact sheet on Construction Site Runoff Control (http://www.epa.gov/npdes/pubs/fact2-6.pdf), "sediment runoff rates from construction sites are typically 10 to 20 times greater than those of agricultural lands, and 1,000 to 2,000 times greater than those of forest lands. During a short period of time, construction sites can contribute more sediment to streams than can be deposited naturally during several decades. The resulting situation, and the contribution of other pollutants from construction sites, can cause physical, chemical, and biological harm to our nation's waters."

Cause	Effect

The University of Minnesota Duluth discharges storm water to several different waters, the following links describe what UMD properties discharge to the following types of waters and what special requirements are placed on these discharges.

• Areas that Discharge into Restricted Waters
• Areas that Discharge into Trout Streams
• Areas that Discharge into TMDL Impaired Waters
• Areas that Discharge into Other MS4's Storm Water Systems

Best Management Practices: New practices will be added as they are completed.

• UMD 401 - Erosion Control Inspection Report
• UMD 401/402 - 2003 Project Managers Training (note: this is a 4.5 MB pdf)
• UMD 402 - Storm Drain Marking

Construction Storm Water Runoff Control Best Management Practice Summaries

UMD 401 - Erosion and Sediment Control Policy

University of Minnesota Standards & Procedures for Construction addresses the University's requirements for design and construction. These standards were updated in 2002 and contain much of the phase II requirements. These existing standards will be reviewed and improved upon.

UMD 402 - Construction Standards Improvements

Standards and procedures are often overlooked if there is not an enforcement requirement. Inspection requirements will be developed that split the responsibility between the contractor, A/E, and the University. A web site has been set up to accept reports of apparent non-compliance.
