Air Permits for Biofuel PlantsPermits 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

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
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
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
PM 2.5 24-hour Design Values
2004 – 2006
(NAAQS Standard is 35 μg/m3)
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
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
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
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
Water Supply Growing demands for
groundwater supplies Requires more information to
plan for the future

Ground Water Supply and Demand – not equally distributed
FAIR
POOR
GOOD
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
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
The New Water Quality The New Water Quality StandardsStandards 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”
Mississippi River = fishable/swimmable
Unnamed Creeknear Davis City = fishable/swimmable
Use Attainability Analysis
A structured scientific assessment of the factors affecting the attainment of the use
May include Physical Chemical Biological and Economic factors
Iowa UA/UAA Process
1. Presumed fishable and swimmable
2. Gather information in the field
3. Compare field data to use definitions and decide which uses are attainable
4. Post on UAA database for input and rulemaking
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
Opportunities Anaerobic Digestion Manure-to-Energy +
Economic opportunity - 750 animal units
Closed-looped systems to process manure and other organic wastes
Community-based, with centralized collectionLivestockEthanol productionCommunity wastewater treatment facilities
Produce biogas and associated value-added products
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

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
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
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
