What was accomplished under these goals?
Illinois Manure Management Plan (IMMP): The Illinois Manure Management Plan training sessions were held to encourage producers and consultants to implement the IMMP planning and recordkeeping tools and the IMMP website (www.immp.uiuc.edu) was further developed during the period of this project. For example in the past year, we held 8 workshops throughout the state starting December 11, 2012 and ending on March 6, 2013. A total of 274 producers, contractors, educators and others participated and were certified at the workshops. Of the 274 certified approximately 32 of those were producers who manage facilities with fewer than 300 animal units (AUs). This was encouraging, given the current statutory requirement for certification is for producers managing 300 AUs or more. For the 2012-2013 season, 57 people signed up to take the CLM on-line quizzes. The Illinois Manure Management Plan Workbook and website will help producers meet compliance guidelines with existing and new water quality regulations. The IMMP tools will be useful to Illinois livestock facilities of all sizes, but are particularly helpful for facilities of 1,000 animal units and larger. Livestock producers have better information regarding the selection of, and investment in, emission control technologies based on the results of the field tests. Approximately 1,000 Illinois livestock producers now have a reporting and recordkeeping tool. Follow-up visits were conducted with producers who use IMMP and with NRCS engineers, in order to help us evaluate the tool's impacts and to gather suggestions for improvements. The IMMP web tool was further refined and improved for Illinois livestock producers. A dairy producer's Comprehensive Nutrient Management Plan (for EQIP cost-share funding) case study was developed for a training course that began in 2011. We developed and delivered a new o-line course to help Technical Service Providers practicing in Illinois write Comprehensive Manure Management Plans. We actively participated in interagency meetings on new NPDES permit rulemaking for Illinois. We have a greatly expanded base for teaching manure nutrient management plan development, including: Horse manure composting program was begun to assist stable managers in NE Illinois to manage manure in more environmentally sustainable ways and especially for diverting horse manure from landfills into better uses, e.g. compost. We have built stakeholder involvement and developedpotential program extent to include new groups, now representing the pathways from production to landfill, nurseries, and other potential end users of composted manure. We have provided much clarity and refinement to the rules basis for Illinois NPDES permit rulemaking for CAFOs and expect this to have a great effect on the quality of the final rules in the state. Research of feedlot runoff was conducted to identify environmental factors affecting the fate and transport of Cryptosporidium parvum in surface and near-surface runoff so that best management practices can be developed to ultimately reduce or eliminate microbial contamination of water resources from feedlot runoff. The results from the small-scale experimental system compare well with results from the larger-scale system in that the C. parvum oocyst recovery in runoff (i.e. escape from the treatment system to the environment) was substantially lower from the vegetated surface when compared to those from the bare surface condition in every case.Results of the feedlot runoff studies showed that vegetated filter areas can be effective management practices, by capturing and treating certain microorganisms that are known to impact human health if they enter drinking water supplies. Various GPS mapping strategies for towed-hose applicators and tanks were evaluated and refined. An Extension team worked with commercial manure haulers to identify a low cost system for as-applied mapping of manure application in crop fields. Results were presented in training sessions to custom manure haulers and to livestock producer audiences. Foam production in deep-pit manure storages is a growing concern for the swine industry.We collected survey information on manure pit foaming problems, conducted tests on commercially available foam suppression agents, and investigated building fires that resulted from ignition of pit foam biogas; we collected a large number of manure samples from foaming and nonfoaming manure pits, for bacterial analysis. Hydrothermal Processing (HTP): The HTP process has the potential to produce up to fifteen U.S. gallons of crude oil product per finishing pig raised. The process can be used on a variety of wet feedstocks to produce oil products. A continuous HTP process for making crude oil product from animal wastes and other agricultural by-products has been licensed to private companies and is nearing commercialization. A pilot plant is under construction for converting swine manure solids to oil. New protocols for describing the products of hydrothermal processing were developed. Studies of hydrothermal processing of livestock manure and various other agricultural feedstocks were completed, and a system of processing that included wastewater treatment by algae was modeled. A modeling analysis was performed of an HTP system that combines feedstocks from a rural community's wastewater treatment and the county's swine finishing facilities. The analysis showed significant financial and environmental advantages of the HTP system compared to conventional wastewater treatment means. Biofilter Studies: Biofilter packing materials and an innovative trickling biofilter were evaluated for their effectiveness in controlling ammonia emissions from swine buildings. A new style of biofilter container was designed, constructed and demonstrated on the University of Illinois livestock farm. Instrumentation was installed on the new biofilter to monitor ammonia removal and concentrations of other gases. Biofilter demonstration site was developed, for swine producer training on how to design, construct, and manage biofilters for ventilation air cleaning. We conducted studies of various biofilter media, especially airflow characteristics linking particle size distribution, moisture content, and other factors. Ammonia removal of biofilters was studied in relation to moisture content of target organic media. We now have a much better understanding of the ammonia removal process, as related to moisture content of organic media. We are better able to predict ammonia removal based on media moisture content and ammonia loading history. We have an improved algorithm for the biofilter design process based on media airflow characteristics and particle sizing. Biofiltration technology for reduction of emissions from swine wean-to-finish confinement buildings were tested. A set of five similar swine buildings on a single farm - one control and two sets of two buildings for treatments - were instrumented with continuous air sampling equipment. Final data analysis showed the effectiveness of the emissions control systems, and results were delivered to the sponsor of the research. Biofilter experiments and demonstrations give livestock producers new information regarding the selection of, and investment in emission control technologies for mechanically ventilated animal buildings. Research results have allowed us to develop new tools for teaching biofilter design and management to producers, contractors, consultants, agencies, and other stakeholders. We held two workshops for agency staff, farmers, and agribusiness to demonstrate biofilter construction and maintenance.

OUTPUTS: Illinois Certified Livestock Manager training continued. We enhanced and delivered for the second year an on-line course to help Technical Service Providers practicing in the Midwestern U.S. write Comprehensive Nutrient Management Plans (CNMPs). We actively participated in interagency meetings on new NPDES permit rulemaking and the revised NRCS 590 standard for Illinois. Hydrothermal processing (HTP) of manure and other waste feedstocks continued, as we tested more feedstocks including algae in the HTP to better understand thermochemical pathways. HTP in conjunction with wastewater treatment and algae production is being developed at a new demonstration center on the University of Illinois campus research farm. A biofilter demonstration site was completed for swine producer training on how to design, construct, and manage biofilters for ventilation air cleaning. We held two workshops for agency staff, farmers, and agribusiness to demonstrate biofilter construction and maintenance. We conducted more studies of biofilter media, especially ammonia removal of biofilters, in relation to moisture content of target organic media.

In this study, a 14.59 percent recovery was observed in the bare condition while only 7.15 percent of the oocysts were recovered from the vegetated condition. Aside from the location where oocysts were initially applied, very few infective oocysts were found in the soil profile. This indicates the oocysts are either strongly absorbed to soil particles and are not easily transported in the soil profile, difficult to extract once equilibrated within the profile, or somehow inactivated in the soil profile. The Illinois Manure Management Plan website (www.immp.uiuc.edu) was further developed. Follow-up visits were conducted with producers who use IMMP and with NRCS engineers, in order to help us evaluate the tool's impacts and to gather suggestions for improvements. PARTICIPANTS: (1) Principle investigator: Ted L. Funk. Liaison with departmental and interdisciplinary teams and manager of reporting. (2) No personnel were supported financially by this project. University of Illinois Extension faculty and staff participated in the training activities listed in the Outputs section. TARGET AUDIENCES: Other scientists and engineers (to help shape future research direction); Extension field staff and educators (assist with producer and consultant training sessions); industry journals; other ag media (introduce technology and invite participation with demonstration projects); State and federal agencies including regulatory (to help advise compliance actions, suggest best management practices, and provide input on regulatory changes); and agri-industries (to invite participation and possible commercialization of new technologies). PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Results of the feedlot runoff studies showed that vegetated filter areas can be effective management practices, by capturing and treating certain microorganisms that are known to impact human health if they enter drinking water supplies. Biofilter experiments and demonstrations give livestock producers new information regarding the selection of, and investment in, emission control technologies for mechanically ventilated animal buildings. Approximately 1,000 Illinois livestock producers now have a reporting and recordkeeping tool, the Illinois Manure Management Plan Workbook and website, which will help producers meet compliance guidelines with existing and new water quality regulations. The IMMP tools will be useful to Illinois livestock facilities of all sizes, but are particularly helpful for facilities of 1,000 animal units and larger.
