    Proposal abstract:

    Summary of the Project

    The goal of this project is to reduce the environmental impacts of dairy farming in the West so as to promote and guarantee sustainability of the milk and cheese industry in the region. The specific objective of this proposal is to train Agricultural Professionals selected across the dairy producing regions in the West on best management practices (BMPs) available to dairy producers for the mitigation of air quality degradation. These professionals will be expected to incorporate these BMPs in their regular outreach activities upon their return to their respective work stations.

    Recently, the EPA initiated a nationwide study to determine what pollutants (ammonia, hydrogen sulfide, volatile organic compounds, and particulates matter: PM10 and PM2.5) and what sizes of concentrated animal feeding operations (CAFOs) may require regulations. In the event that the regulations are put into effect, some or all facilities may be required to incorporate or install BMPs to mitigate emissions of these pollutants. In addition, several states in the West such as Idaho, California, and Arizona, have enacted air quality regulations that require dairy and livestock producers to reduce impacts either statewide or within air-sheds that are in noncompliance with the clean air act (CAA). Dairy producers, therefore, need to be aware of the available effective BMPs that they could utilize in order to comply with either the federal or state regulations. The proposed extension education will address these regulations, and introduce respective BMPs for alleviating the respective emissions in order to prepare the producers in advance to deal with these issues today and/or when (and if) the regulations come into effect.
    This proposal is a multi-State, multi-disciplinary Extension Education Project to provide a unified approach to providing this important service to the livestock industry. The proposed project will, therefore, rely on the air quality research and extension expertise from specialists across the West to develop an initial and continuous air quality education program for agricultural professionals. Four hands-on educational workshops will be conducted across the Western region, and will serve as an in-depth introduction to air quality issues, regulations and control practices. Workshop participants will then participate in a series of 10 live web-cast presentations on specific air quality issues. Finally, archived web-casts, workshop presentations, video tours, and other educational information will be made available on a public website.
    The effectiveness of this educational project will be assessed using tools such as: (1) pre & post quizzes during training, (2) hit counter in the web-site, (3) number of professionals incorporating air quality information from this program into their education or outreach programs, (4) surveys of workshop participant’s intentions of incorporating air quality issues in their programs, (5) request of technical assistance of air quality BMPs by producers, and (6) assessment of reduction of air pollution complaints.

    This project is also expected to serve as a quasi-pilot educational program and will provide other interested agricultural professionals educators with a template to conduct similar programs elsewhere in the nation. Program material developed under this program will be available on the web to project participants, extension educators, and to the public.

    Goals, Objectives and Outcomes

    The goal of this project is to reduce the environmental impacts of dairy farms in the West. The objective of this proposal is to train Agricultural Professionals from State Cooperative Extension, NRCS, Soil & Water Conservation Districts, state regulatory agencies, and producer groups in the dairy producing regions in the West on environmentally sound practices that can be used on facilities and to promote and guarantee sustainability of the milk and cheese industry. The educational program will equip these agricultural professionals with knowledge and skills they can use to advance best management practices (BMPs) necessary to reduce air pollution from dairies in their outreach activities. As a result of this education initiative, we expect at least 50% of dairy producers to implement recommended practices and/or technologies by the third year of the program.

    In brief, it is projected that the benefits of this educational program will ultimately be reflected in less air pollution from the dairy industry and therefore, less costly nuisance lawsuits that continually threaten the sustainability of this industry. This project thus explicitly addresses three of the five Western SARE and the National SARE goals, namely: (1) Enhanced environmental quality and the natural resource base upon which the agricultural economy depends, (2) Sustained economic viability of agricultural operations and their communities, and (3) Enhanced quality of life for farmers and ranchers and society as a whole.
