  1. Regulatory Update Wayne GieselmanDivision Administrator

  2. Big Issues & Opportunities • Air Quality • Biofuels • Green House Gases • Water Quantity • Landfills • UAAs • Opportunities • Anaerobic digester • Biofuels • Enforcement and Field Office Priorities

  3. Division Priorities • Human Health and the Environment • Empowering communities • Focused on greatest risks • Develop new revenue sources • Empower employees to improve program effectiveness

  4. Air Permits for Biofuel Plants Permits Issued • Dry mill ethanol plants 58 5,773 MM gals • Wet Mill ethanol plants 4 559 MM gals • Biodiesel plants 13 448 MM gals • Total 75 6,780 MM gals Applications under review • 4 dry mill ethanol and 6 biodiesel • Proposed = 780 MM gals • DNR reviews and issues permits usually < 90 days • Less applications recently Updated Aug. 17, 2007

  5. Biodiesel and Ethanol PlantsJuly 2007

  6. How Far Can You Go? • 0.36 bushels corn/gal ethanol • 121,800 bu/day for 120 mgy plant • 200 – 300 trucks per day for corn • 50 to 60 mile radius needed for corn

  7. Greenhouse Gases • New legislation (SF485) • Requires DNR to • Quantify increases in GHG emissions • Include GHG in emissions inventories in 2008 • Establish voluntary climate registry by 2009 • Establish the Iowa Climate Change Advisory Council • No authority to regulate GHG emissions

  8. Air Quality In Iowa • Marginally meeting new 24-hr PM2.5 standard • Some parts of eastern Iowa may go into nonattainment next year • EPA proposed tightening 8-hr ozone standard • Final standard due March 2008 • Portions of Iowa could be in nonattainment depending on final standard

  9. PM 2.5 24-hour Design Values 2004 – 2006 (NAAQS Standard is 35 μg/m3)

  10. Solid Waste (aka Landfill Liners) • Implementing federal program • Started in 2002 – Iowa rules inconsistent with federal rules • Why? We need to do a better job of protecting groundwater

  11. The Issue • Partially lined landfills often on top of unlined areas • Cannot tell if contamination comes from lined or unlined areas • Need data and a method to show new leachate does not pollute groundwater

  12. Solutions Liners Required by Oct. 1; 3 Years to Comply Partially lined landfills have several options • Use modeling software to show side slopes are working • Construct a side liner • Continue to place waste on bottom liner for 3 years then move it to newly constructed area

  13. Changes • Ensures an engineered liner is installed to prevent groundwater contamination • Improved groundwater sampling and monitoring • Increase time for permit renewals from 3 to 5 years • Research and development permit • Allows adding liquids • Allows cover, planting trees

  14. Water Supply • Growing demands for groundwater supplies • Requires more information to plan for the future

  15. GOOD FAIR POOR Ground Water Supply and Demand – not equally distributed

  16. Groundwater Supply • Proposed comprehensive study - $1.65 million annually • Currently funded at $480 thousand • Will pursue total funding • First year: Characterize the Dakota Sandstone – main bedrock aquifer in NW • Develop example products to show what could be done statewide

  17. First Year – Dakota Aquifer • Compiling available information • Geology • Water-yield characteristics • Water withdrawals • Water levels • Water quality • Creating an on-line data information system Making sure we won’t “dry up” the state

  18. The New Water Quality Standards • All non-designated perennial streams and intermittent streams with perennial pools are designated as Class A1, B(WW-1), i.e. “fishable/swimmable” 26,000 miles of perennial streams - 12,000 miles of previously designated streams 14,000 new miles presumed to be “fishable/swimmable”

  19. Mississippi River = fishable/swimmable

  20. Unnamed Creeknear Davis City = fishable/swimmable

  21. Use Attainability Analysis A structuredscientific assessment of the factors affecting the attainment of the use May include • Physical • Chemical • Biological and • Economic factors

  22. Iowa UA/UAA Process • Presumedfishable and swimmable • Gather information in the field • Compare field data to use definitions and decide which uses are attainable • Post on UAA database for input and rulemaking

  23. What’s Happening Now? • Rules effective March 22, 2006, but still awaiting EPA approval • Criteria issues • The UHL contract ends December 2007 • Nearing end of field season #2 • NOIA to EPC in October

  24. OpportunitiesAnaerobic DigestionManure-to-Energy + • Economic opportunity - 750 animal units • Closed-looped systems to process manure and other organic wastes • Community-based, with centralized collection • Livestock • Ethanol production • Community wastewater treatment facilities • Produce biogas and associated value-added products

  25. Environmental Benefits • Reduces odors by 90 percent or more • Reduces GHG damage to the atmosphere: CO2 X 21 = CH4 • Reduces nitrate pollution to water from faster nutrient uptake* • Reduces fossil fuel use and the emissions associated with fossil fuel use *Source: Danish Agricultural Advisory Service, Crop Production (15-year study)

  26. Opportunities2007 ESD Enforcement Goals • Develop, track and measure environmental indicators for each ESD program area • Review and update priority areas for compliance and enforcement in each ESD program area • Resolve or set hearing on all existing appeals by July 1

  27. Enforcement Priorities • Air Quality • Asbestos violations • At schools, hospitals and community centers • Major source and/or repeat air quality violations • Landfills • Inspect priority areas such as landfills • Decrease inspections where problems are under control, i.e., transfer stations • Set criteria for when open dumps will be inspected

  28. Future Forecasting • More regional, community-driven problem solving with DNR as technical advisor • Making a difference – attacking problem areas where efforts pay off in environmental improvements • Emphasis on prevention – pre-construction meetings, increased stakeholder involvement • Need for sustainable funding sources as EPA asks for more • Performance Tracking
