Model Clearinghouse Information Storage and Retrieval System
Record Details

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.
