  AR only)
• Downward Reclassification Petition filed with EPA
  July 15, 2004
• Reclassified downward to Marginal
• EDZ application submitted to EPA Region 6
  September 23, 2005

• 10 helicopter flight days within ozone season
• Purpose Provide three-dimensional air quality
  and meteorological data that cannot be measured
  by ground-based instruments.

UAH Mobile Integrated Profiling System (MIPS)

• Contract between State of Arkansas (ADEQ) and UAH
• 73,399
• 100 Title V permit fees
• Located in Crittenden County during ozone season
• Collects real-time data on upper-air wind
  speeds/directions and other atmospheric
  conditions

Supplemental Air Quality Monitoring

• Deploy two mobile ambient air quality ozone
  monitors in Crittenden County (Clarkedale and
  Earle) ADEQ
• Deploy ambient air quality ozone monitor east of
  Memphis - TVA

13
Existing and new temporary monitors
14
Economic Development Zone (EDZ) for Crittenden
County

• Establish pursuant to 42 U.S.C. 7503
• Allow new emissions sources to be located in
  county
• Establish socio-economic need
• Demonstrate through air quality modeling that new
  emissions would not affect reattainment or
  maintenance
• Establish offset pool for sustainable growth
  through State regulation

15
EDZ Timeline

• Initial request made June 9, 2004
• EDZ Application submitted to EPA Region 6
  September 23, 2005
• Meeting with OAQPS November 3, 2005

Targeted EDZ Emission Allocations Proposed
Regulation

• 1900 tpy VOC 300 tpy NOx by January 1, 2007
• 3700 tpy VOC 800 tpy NOx by January 1, 2009

20
Targeted EDZ Emission Allocations Proposed
Regulation

• Petition requirements
• Socio-economic impact
• Project schedule
• Distinct from permit application

21
Targeted EDZ Emission Allocations Proposed
Regulation

• Additional requirements
• Input from local government
• Economic impact justification
• Public comment
• Permit conditional upon petition approval

22
An Innovation Authorized by the Clean Air Act

• Economic Development Zones are authorized within
  the Act
• Zones are identified by the Administrator in
  conjunction with the Secretary of HUD
• EDZ is an innovative strategy tailored to fit a
  narrow, targeted problem

23
Limited in Scope

• EDZ sources must not interfere with reattainment
  of the relevant standard
• Zones are intended to allow limited, planned
  economic growth while preserving public health
• EDZs allow a limited alternative to offsets, but
  does not impact other NNSR requirements (LAER,
  etc.)

24
Work With Region VI

• Little guidance to direct our efforts
• ADEQ has worked closely with Region VI on a
  framework document to produce a petition which
  addresses both air quality and socio-economic
  components
