Subsoiling Rain Gardens None of us is as smart as all of us. - Japanese proverb Composting is a Manufacturing Process Composters are Product Manufacturers! Biofiltration Device Not Manure or Aged Manure or Decomposing Garbage Urban Ponds 3
Promoting the proper use of compost products, reduces failures in the field Which hurts end users and composters! Seal of Testing Assurance Program WHAT IS IT? Compost testing and information disclosure program (employing standardized practices) PURPOSE To assist compost end users purchase the product they require for their particular project To assure that compost end users know the characteristics of the compost products they purchase To improve overall customer confidence in compost selection and utilization GOALS: To improve customer confidence in compost selection (and utilization) To improve overall customer satisfaction, as well as field results To improve compost purchasing decisions To promote customer-oriented composters Move industry towards standardized test methods 4

I have noticed over the years that only those people who are unfamiliar with the challenges of controlling erosion and sediment transport on highway construction projects, think that 100% compliance is achievable. Ken Stone, Washington State DOT Overall, the key is changing behaviors AGC/NDOR Partners in Construction Environmental Mistakes are Costly Loss of habitat that may not be recoverable Restoration costs Lost time and resources from other issues Attraction of management to your issues Loss of agency trust Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago. Horace Mann must stick with the tried and true Must build safe roads must destroy natural resources must try all new devices and tricks Erosion Control is A Risk Management Activity Based on collecting facts and information TRANS 401 offers NO IMMUNITY for WisDOT! SUCCESSFUL Compliance = NO RELEASES to waters of the state Use the cookie cutter method Design an innovative method Take a gamble 6
Identify and Assess Environmental Risk Factors (Professional Judgment) Receiving Waters Drainage Pattern Winter Close Out Soil Types Slopes Staging High Value Adjacent Resources Time of Year for Earth Disturbing Activities USACE Permit, DNR Letters, Environmental Commitments Political Notoriety (Brule, Kinnickinnic Rivers) Settling Time 1 Micron size particle takes 55 hours to settle 1 foot Soil Particle Size Reality for Some Soil Types* Any runoff from a project can produce a release The relationship of soil type, moisture content and runoff volume determine whether you have a release 2-year 24 hour is the design standard *Even without human error Do Clay Particles Settle? Colloidal solids, also called non-settable solids will not settle out for years Flocculants can change the electrical charge of clay particles causing them to coagulate and settle out Requires testing to determine chemical makeup, mixing time, and settling time May be practicable for small pumping operations and small drainage areas with large storage options Does not work on all soils Polymers cause coagulation of sediment particles which then allows for more effective gravity settling Great for silt and clay applications Must be on DNRs approved list Polymers 7
Creativity comes from a conflict of ideas. Donatella Versace Time 0 1 min. 15 min. 2 hours Polymers Not on PAL Long and narrow traps are generally more effective than round or square configurations No special provision or standard detail drawings currently available Prior to utilizing on a WisDOT project, call Mary Anne Lowndes for toxicity testing approvals (608-261-6420) for the product WisDOT/Contractor is proposing to use 8

Heavy Duty Silt Fence Poor: if one BMP is not effective more of the same will give the same results Good: utilize different methods in series if one method doesn t work 11
