1. Major Environmental Legislation Affecting Livestock Agriculture in the US Year Land Water Air Biodiversity 1901 USDA establishes grazing regulations in forest reserves 1934 Taylor Grazing Act 1935 Soil Conservation Service established 1969 ------------National Environmental Protection Act---------------- 1970 Clean Air Act 1972 Clean Water Act 1973 Endangered Species Act 1974 25-year, 24 hour rainfall discharge requirement

2. Year Land Water Air Biodiversity 1976 Definition of CAFO’s as sources of point source pollution 1980 Comprehensive Environmental and Liability Act (CERCLA) 1985 Food Security Act establishes Conservation Reserve Program 1987 Agriculture exempted from Clean Water Act 1996 Federal Agriculture Improvement and Reform Act 1997 Established EQIP Amended Clean Air Act; Ambient Air Quality Standards revised 1998 Clean Water Action Plan; Unified National Strategy for Animal Feeding Operations 2002 Revised CAFO regulations

3. Land Regulations 1901 –USDA developed principles to regulate grazing within forage reserves Grazing was allowed if it did not damage water supplies 1934 –Taylor Grazing Act Placed all public lands, not controlled by the US Forest Service, into grazing districts controlled by the Grazing Service Department in the Department of the Interior Later became the Bureau of Land Management (BLM) BLM charged with halting overgrazing and soil destruction through Grazing Management Plans 1969 –National Environmental Policy Act All agencies required to write environmental impact statements for all major federal actions that might affect the environment BLM required to write statements for all local grazing programs

4. 1985 –Food Security Act Developed the Conservation Reserve Program (CRP) –Took row cropland in highly erodible areas out of crop production and seeded with forages for an annual payment –Contracts lasted 10 to 15 years –Forage couldn’t be grazed or harvested unless federal emergency was declared –Effects »Seeded large amount of land in forage »Reduced soil erosion and water pollution while increasing wildlife habitat »Inflated price of local crop and pastureland

5. Water Regulations 1973 –Clean Water Act Goal –Restore and maintain the chemical, physical, and biological integrity of the nation’s waters Defined point source and nonpoint source pollution –Point source pollution »Water pollution from facilities that discharge to water resources through a discernible confined and discrete conveyance including but not limited to a pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, or vessel or floating craft from which pollutants might be discharged »May be controlled by technology-based approaches »Point source rules prohibit discharge of pollutants from a point source to waters of the US except as authorized by a NPDES permit (National Pollution Discharge Elimination System) »Point sources specifically include Concentrated Animal Feeding Operations (CAFOS) and regulated by the CAFO rules

6. –Nonpoint source pollution »Water pollution whose source can not be identified »Represents 60 to 80% of water pollution today »Usually occurs over a broad area »Technology-based controls are inadequate »Controlled by Best Management Practices (BMP’s) »Regulated by Total Maximum Daily Load (TMDL) regulations 1999 –Unified National Strategy for Animal Feeding Operations Developed by EPA and USDA Goal is that all Animal Feeding Operations (AFO’s) develop and implement Comprehensive Nutrient Management Plans (CNMP’s) –The largest 5% of AFO’s would be required to develop a CNMP by EPA as part of the NPDES permitting process –The remaining 95% of the AFO’s would be expected to develop a CNMP voluntarily using locally focused incentive programs –CNMP should have: »A Feed Management Plan »A Manure Storage and Handling Plan »A Land Application Plan 2002 –New CAFO regulations implemented

7. CAFO Regulations Definition –A ‘CAFO’ is an ‘AFO’ with a specific size and/or danger to water quality As ‘AFO’ is a lot or facility where: –Animals have been, are, or will be stabled or confined and fed or maintained for any portion of the day for a total of 45 days or more in any 12- month period, and –crops, vegetation, forage growth, or post-harvest residues are not sustained in a normal growing season over any portion of the lot or facility CAFOs are AFOs that meet size or discharge criteria

8. Size criteria –BaseAnimal Unit Slaughter and feeder cattle1.0 Mature dairy cattle1.4 Butcher or breeding swine, >55 lb0.4 Growing swine, <55 lb0.1 Sheep0.1 Horses2.0 Turkeys0.018 Broiler or layer chickens0.01 –Calculation examples: 1000 growing steers x 1.0 = 1000 AU 2500 100-lb growing pigs x 0.4 = 1000 AU 500 growing beef cattle x 1.0 = 500 AU 1000 growing-finishing pigs x 0.4 = 400 AU Total 900 AU

9. Requirements based on size –All Animal Feeding Operations Retain manure on-site between periods of land application Observe land application separation distances Report any manure releases Correctly dispose of animal mortalities –AFOs with > 500 AU An annual Manure Management Plan Manure can only be applied a certified manure applicator Building construction must be based on the state’s Master Matrix –AFOs with > 1000 AU or > 500 AU if stream runs through lot or a man-made conveyance discharges runoff from an AFO to a stream or river Requires an annual Nutrient Management Plan or a Comprehensive Nutrient Management Plan (if applying for government assistance) Operation must apply for a NPDES permit Manure can only be applied a certified manure applicator Building construction must be based on the state’s Master Matrix

10. Manure Management Plan –A tool to balance manure nutrient application with crop yields –Elements Number of livestock Amounts of manure produced Nutrient concentrations of manure Number of acres of each crop available for manure application Yields of each crop Amount of manure that can be applied to achieve either Nitrogen or Phosphorus balance –All plans must be based on a P-index –Can be prepared by a producer

11. Nutrient Management Plan –Elements All components of a manure management plan Mortality handling Diversions of clean water around facilities Preventing contact of animals with water resources Chemical handling Manure storage and application –Prepared by Technical Service Provider Comprehensive Nutrient Management Plan –Elements Components of a Nutrient Management Plan Land treatment practices to prevent erosion and nutrient runoff Feed management practices to reduce nutrient excretion Other manure utilization activities Additional record keeping –Prepared by USDA-NRCS or a certified Technical Service Provider

12. NPDES Permits –Application 180 days before new or renewal permit is implemented –Parts of an NPDES permit Effluent limitations –Production area »Discharges from CAFOs with NPDES permits are allowed from production areas that are well-designed, built and operated to handle precipitation up to a: »25-year, 24 hour rainfall from cattle, sheep, and horse CAFOs »100-year, 24 hour rainfall from swine, turkey, chicken, and veal CAFOs* –Land application area »Manure, litter, and wastewater must be applied to land using BMP’s

13. Record-keeping requirements –Records kept for 5 years Nutrient management plan –Must show implementation Manure, litter or wastewater analysis records Soil analysis records Production area records Land application records Animal records Discharge report –All discharges must be verbally reported within 24 hours and in writing within 5 days –Report »What caused problem; how long it lasted; how you stopped it; and how you will prevent it in the future

14. Bottom line Discharges of manure, litter or wastewater from CAFO’s without NPDES permits are subject to prosecution resulting in major penalties

15. Total Maximum Daily Loads (TMDLs) Used to limit nonpoint source water pollution primarily by implementation of Best Management Practices (BMPs) Defined as a written qualitative plan and analysis for attaining and maintaining water quality standards in all seasons for a specific pollutant Written for all water sources in a state that do not meet state water quality standards according to the Section 303(d) impaired waters list conducted every 2 years –Impaired water bodies do not meet designated uses for recreation, fishing or drinking Prepared by state authorities with local input –Must be approved by US-EPA

16. Implications for livestock agriculture –Manure application Injection into soil Application onto frozen soil –Pasture streams Buffer strips Controlled access Load allocations from nonpoint sources controlled by voluntary approaches If voluntary approaches don’t work: –EPA may cut federal funding to state –Congress may pass legislation tying compliance to crop price supports A TDML must improve the water quality in a specific body of water within 10 years

17. Programs to assist livestock producers in improving water quality 1985 –Food Security Act Developed the Conservation Reserve Program (CRP) –Reduced soil erosion –Conserved wetlands 1996 –Federal Agriculture Improvement and Reform Act Initiated the Environmental Quality Incentive Program (EQIP) –Provides technical assistance and provides 75% cost-share to environmental improvements –60% of the total funding targeted for livestock –Medium and small AFO’s »Can receive financial assistance for waste management structures and nutrient management plans –Large CAFO’s »Can receive financial assistance for nutrient management plans –Contracts are for 1 to 10 years –Maximum contract is for $450,000

18. 2002 Food Security and Rural Investment Act –Conservation Security Program Intended to reward producers for past conservation measures and encourage additional measures Payments –Base »5 to 15 % of rent »Max. $20,000 to $45,000/yr –75% cost-share on improvements Targeted watersheds Grazing –Requires grazing plan –Access to stream limited to 25% of time –Grazing records –Prevent animal concentration near streams

19. Air Quality Clean air act (1970, amended in 1997) –EPA charged with the authority to regulate major sources of air pollution to protect and enhance the quality of the nation’s air resources EPA delegated states to implement federal air quality standards, federal monitoring networks, and permitting functions EPA established a list of National Ambient Air Quality Standards (NAAQS) for six principal air pollutants that may compromise human health or well-being

20. Air pollutants regulated by EPA Major air pollutants NAAQS produced on AFOs Carbon monoxide (CO) * Lead (Pb) * Nitrogen dioxide * * Ozone (O 3 ), * * formed from volatile organic compounds (VOC’s) and nitrous oxides (NOx) Particulate matter, * * PM 10 (2.5 um < x < 10 um) from dust PM 2.5 ( < 2.5 um) from ammonia (NH 3 ) with NO 3, SO 4 or VOC’s Sulfur Dioxide (SO 2 ) * Hydrogen sulfide (H 2 S) *

21. Major sources of these pollutants are defined as emitting more than 100 tons of any single pollutant per year Emissions –Point source pollution Sources that can traced to a single point –Point sources on CAFOs include hay grinding, grain unloading, and feed loading –Fugitive emissions Sources not traceable to a single emission point Because of lack of monitoring, fugitive emissions have not been included in the emission inventories of AFOs except in several western states –Therefore, Clean Air Act hasn’t been applied to AFOs until recently Requirements for major emitters –Pay emission fees –Apply for a Federal Operating Permit –Prepare an emissions inventory Although AFOs have not needed Federal Operating Permits, states have required permits based on state air quality regulations

22. States implementing air quality standards on AFOs –Odors Missouri, 1998 North Carolina, 1998 Colorado, 2001 –Hydrogen sulfide (H 2 S) California, 1969 Minnesota, 2001 Iowa, 2004 –15 ppb can’t be exceeded more than 7 times per year measured at neighboring houses, churches, and public places –VOCs California

23. Legislation used in air quality lawsuits –Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Developed in 1980 as “Superfund” Requires EPA to respond to the release of hazardous substances like for NH 3, H 2 S, and other pollutants at amounts greater than 100 lb/day Requires person in charge of facility to report unauthorized releases of hazardous substances to the National Response Center Because of lack of data and monitoring, CERCLA has only been recently used on several AFOs in Iowa –4 Swine operations were found to be emitting 224 to 814 lb NH 3 /day (2004)

24. Biodiversity 1973 –Endanger Species Act Any species of animal, plant or invertabrate could be listed as endangered or threatened It is illegal or kill an endangered species or disrupt its habitat
