12 Acres needed for land spreading of animal waste How many acres are needed per AU for land spreading of animal waste for Phosphorus? Clemson University, University of Wisconsin 2 to 3 acres per AU. 80,000 AU in Brown County x 2 acres/ AU = 160,000 acres cropland needed. Distribution ib ti of Livestock operations. Density standards need to be developed or other waste treatment technologies promoted and funded. 12

13 Land Application of Wastes Approximately 162,000 acres of cropland in Brown County. 1/3 of Cropland is estimated to have spreading restrictions such as: Set backs to streams Set backs from wells Set backs from wetlands Setbacks from KARST, Bedrock, Bd sinkholes 106,920 acres of cropland (66%) is more accurate estimate of spread able cropland. 13

14 Other Waste DNR approved land spreading sites Brown County 2/14/07: Industrial= 566 sites, 23,214 acres, 18 facilities. Municipal = 243 sites, 4854 acres, 9 facilities. Septage= 31 sites 1300 acres, 8 facilities. Total = 29,368.9 acres / 162,000 acres total cropland acres in Brown County = 18% of cropland approved for landspreadingof other wastes. 14

15 How much Waste is being land applied? Animal waste per year from di dairy and beef livestock = 551,921,154 gal per year. Industrial Municipal Septic waste land applied in 2008 = 41,759,400, gallons/ year. (DNR Form ) Is EQUAL distribution of 593 million gallons of waste per year on 106,920 acres of cropland possible? 15

21 Do Nutrient Management Plans and P Index less than 6 protect Water quality? 2010 nutrient management plans = 115,000/162,000 acres of cropland covered (71%) Are nutrient management plans accurate or really being implemented? Pi Private agronomists it NE WI say about 50% are currently implemented within reason. Is correct information being entered into P Index? 21

22 PI 6 agronomic based Not Water Quality Based The DNR will not seek to base nutrient management planning on the potential delivery of nutrients to surface water. Rather, nutrients will be managed in accordance with the needs of a crop. (June 23, 2010 Wisconsin DNR Board approves changes to NR 151 ) Rotation Soil test Rotation Soil test PI P ppm PI P ppm

29 Conclusions of TMDL Phosphorus Mapping Project Soil P ppm better indicator of phosphorus delivery from agriculture fields than P Index. 99.9% of current 590 plans meet P Index yet TMDL identifies Agriculture sources of phosphorus at 46 % and water quality monitoring identifies stream phosphorus levels at greater than.075 ppm. 92 of 132 (70%) of the agriculture fields mapped with over 75 ppm of phosphorus had a stream which intersected the agriculture field as a delivery point for phosphorus. Many of the high soil phosphorus ppm fields are located in close proximity to livestock facilities where historical farm building sites were located. The GIS mapping of phosphorus ppm on a field basis could be used to monitor phosphorus levels by field and be used to focus conservation resources to highest Phosphorus ppm fields 29

31 February 14, 2006 DNR ISSUES BOIL WATER NOTICE FOR WAYSIDE AREA Green Bay In response to private well sampling being conducted in the Wayside area of the Town of Morrison in Brown County, the DNR has issued a Boil Water advisory for private wells in this area. Several area residents began sampling their wells after a manure smell was noted in their water. Sample results from the Brown County Health Department, the Department of Natural Resources, and a local licensed pump installer showed greater than 50% of the wells contained coliform bacteria, and are judged to be bacteriologically unsafe. 31

42 Summary of Morrison Wll Well contamination ti reports peaked kdin January May 2006 and wells tested Morrison Feb May Over 100 wells contaminated from bacteria or Nitrates. 34% >10ppm N. 23 Wells replaced in State zone of eligibility near Wayside $245,098 (state), $74,756 cost to landowner. 51 wells were properly p abandoned in Over 200 Karst features identified by UWGB. Northeast Wisconsin Karst Task Force assembled and completed its report and recommendations February Legislative changes have yet to be enacted to protect groundwater in Karst areas from land application of wastes. 42

43 Conclusion from 2006 Brown County Investigation of Morrison Well Contamination problem Several Factors led to contamination of over 100 wells in Morrison in A combination of wastes (animal, industrial, municipal) were land applied in winter of 2006 on frozen ground that has shallow soil or Karst features with a direct conduit to groundwater. Significant rainfall events in January and February Fb contributed tib t dto the runoff. Current nutrient management plan (590) requirements, and other land application requirements were not sufficiently designed or monitored to prevent the pollution of wells in the Karst topography of Morrison Township. 43

49 Needs Carbonate Bedrock Management Zone Legislation to protect Karst Area groundwater. Mapping of Karst features on field basis to help identify land application restricted areas. Unification of administrative codes regarding land application of wastes. Nutrient Management Plans needs to include all wastes. Animal waste storage facilities intended for Animal waste, other wastes need their own storage or waste treatment facilities. Sustainability limits on livestock concentrations. 49

50 Education needed Survey of Dairy Farmers in Lower Fox by UW ( February 2007) 168 (58%) responded (CAFO s not in survey) 86% agreed it is their responsibility to protect WQ. Only 14% would be willing to pay more to improve WQ. Twice as many (36%) identified Waterfowl droppings as more serious than Agriculture (18%). Respondents see water pollution as generated tdprincipally i by non Ag sources. Two most influential factors are profitability (88%) and out of pocket expense (87%). 75% will maintain or expand herd size in next 5 years. 50

51 Opportunities Nutrient Management state required, 2010 Brown County 115,000/ 162,000 acres Need better plan implementation, revised PI targets lower than 6 for surface water protection. Winter spreading plans 100 per year GIS Monitoring of PPM Phosphorusby field to monitor progress and direct resources. Promotion of new technologies Funding by state of waste water treatment, digesters, dewatering, Waste Transformation Technology to overcome cropland shortage and increase sustainability. Consistent tcompliance of enforcement Rural vs. Urban Compliance. Adequate staff Enforce, inspect, monitor. Green Bay Metro Sewage has 100 employees to monitor estimated 200,000 human residents. 80,000 animal units = 1,440,000 humans and there County, DNR, Private staff monitoring animal waste.
