The report also references a vacant seat on the EENR Steering Committee specifically tied to airport issues, including noise and emissions from aircraft, for which the City of Des Moines applied. Membership would require attendance at four EENR Steering Committee meetings per year at a cost of $968 annually for NLC direct member status.
