Comprehensive Approach to Stewardship Stream Restoration Reforestation Native meadows Green technology
CAFO Concentrated Animal Feeding Operation Delawares program became effective on September 11, 2005, as required by the EPA under the Clean Water Act Primary goal is to eliminate the discharge of pollutants Delaware Park submitted an NOI to comply with CAFO regulations and completed implementation during the spring of 2006
Project Goals A two-fold goal to address the concentration of non-point source pollution as a means to enhance watershed quality Treat run-off from daily equine operations and remove run-off from the stormwater system Direct stormwater run-off away from barns and stables
Equine Activity Total Capacity March- May June- Oct NovDec-Feb 147510001350750 Less than 100 In 2005, this generated 27,006,397 lbs of straw and wood shavings
Treating Daily Equine Operations 1.Wash stalls- carries run-off directly to the sewer system, bypassing the stormwater ditch system 2.Manure bins- carport roofing limits potential for nutrient run-off
Wash stalls Concrete padsDrains directly to sewer system
An increased filtration area also helps to slow run-off velocities
Components of the Bioretention Facility Bioretention basin with 6 under drain pipe Bioretention media (equal parts sand, peat, triple-shredded hardwood mulch) Fore bay Dry detention pond Emergency Spillway into dry detention pond
Near Project Completion Conversion from an open field… To a bioretention facility, improving water quality
Dry detention pond Bioretention basin Fore bay June 26, 2006
Results The wash stalls and manure bin covers have generally met the intent of the CAFO regulation. Conclusive qualitative results for the rain gardens and bioretention facility are not yet available.
