  1. Renewable Energy/Energy EfficiencyAn Air Permitting Perspective Roland C. Hea, P.E. Permitting Section Supervisor Air Pollution Control Division January 24, 2006

  2. Energy Efficiency • Often will not have air permitting impacts • Could /should lead to reductions in pollutant emissions • Some permit changes could be needed for new equipment

  3. Renewable Energy • Wind, solar and geothermal – generally no big air permitting issues • Biomass – changes in fuel types • Combustion processes • Fuel variability • Air emissions impacts

  4. Permitting Considerations • Stationary sources – boilers, process heaters, engines, kilns, etc. • Evaluation of emissions • Opacity (smoke) concerns • Control technology standards • Does source meet applicable requirements?

  5. Recent Permits/Applications • Three new ethanol plants permitted in 2005 (each > 42 million gallons/year) • Biodiesel plant permitted in 2005 (process up to 3 million gallons vegetable oil/year) • Proposed ethanol plant using manure as fuel • One electric utility testing sawdust • Smaller biomass-fired boilers for space heating

  6. Technical Challenges • Lack of available emissions data • Not readily setup for frequent fuel switching • Pollution controls – availability and cost • Performance tests and monitoring NPS Photo

  7. Other Challenges • Past experiences for permit writers • Public perceptions • Prioritizing resources • Limited mechanisms for looking at other environmental benefits • Existing regulations/policies often do not anticipate new technologies

  8. Potential Solutions • Enhance communication between permit applicants, regulators, and communities • Train permit engineers on emerging technologies • Share emissions data • Develop specific exemptions for renewable energy pilot or demonstration projects
