Issue: Region X is seeking concurrence from the Model Clearinghouse of an alternative modeling process pursued under Condition 3 in Section 3.2.2.e in Appendix W for modeling emissions in an Arctic Marine Ice Free environment. C/H Response: Model Clearinghouse concurs on the use of AERMOD-COARE in specific applications covered under Region 10’s approval process for modeling in the ice free environments of the Beaufort and Chukchi Seas. As noted in Region 10’s memorandum, should a project proponent desire to use AERMOD-COARE in another Arctic Marine Ice Free environment, a request must be made to Region 10 prior to the submission of an ambient air quality impact analysis that includes appropriate references and technical justifications pursuant under Condition 3 in Section 3.2.2.e in Appendix W.
