Title: Renewable Energy/Energy Efficiency An Air Permitting Perspective


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
    gt 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

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
