9 Overview (cont d) Pre-meeting with Shell Offshore Incorporated (SOI) in early 2006 R10 Has Permitting Authority in OCS Follow AK Regulations Recommended CALPUFF V6.0 Recommended Met Data Collection Minor Source or PSD

10 Overview (cont d) OAQPS suggested minor source permit application Submitted two minor source permit applications in late 2006 under AK minor source rules Kulluk Frontier Discoverer

11 Overview (cont d) AQIA Issues Encountered ISC-PRIME in Screening Mode and not OCD Not Evaluated in OCS Arctic Conditions Background AQ Data Cumulative Analysis Ambient Air/Exclusion Zone Provide Operating Scenarios Permit Conditions

12 Overview (cont d) Public comments and issue final permit Appeal to EAB in summer 2007 Remanded d back to R10 in months because of stationary source definition Lack permit conditions to prevent NAAQS violations

13 Overview (cont d) In early 2008, one minor source permit for Kulluk 80 days per drill site 160-day drilling season 1000-m separate distance 245 tns/yr at each drill site Justify single stationary ti source definition iti No met data collection as permit condition

14 Objective OEA decided need to collect representative/onsite meteorological variable data Use appropriate refined dispersion model Address public comments For future drilling and processing projects

15 Objective (cont d) Verbal and written communications to SOI Near shore data not representative Surface Upper Air Collect data in OCS using buoys Brooks Range influence Data used on a case-by-case basis Objections from Shell

16 Letter to OAQPS Objective (cont d) Meteorological buoys MM5/WRF-to-CALPUFF (i.e., BARF) CALPUFF over water option-near field Criteria of met variable data acceptance Precedent Communications University of Alaska Mineral Management Service

17 Arctic Condition Harsh and dangerous environment Ice Limit it data collection period Disengaging and loosing anchored buoys Tipping and overturning buoys Accessibility for audits

18 Arctic Conditions (cont d) Polar Bears May 2008 listed as Threatened Species Locating equipment Expensive Buoys: 75K to $300K Four disposable or anchored buoys plus replacements Buoys for Beaufort Sea and Chukchi Sea
