INFLATION REDUCTION ACT (IRA) – COMMUNITY-ORIENTED METHANE AND CO-POLLUTANT EMISSION MEASUREMENTS IN THE APPALACHIAN REGION (COMPEAR) THIS PROJECT WILL MEASURE EMISSIONS OF METHANE AND CO-EMITTED SPECIES IN AND AROUND CJ/EJ COMMUNITIES IN THE APPALACHIAN REGION. THE PROJECT WILL USE BOTH MOBILE AND STATIONARY MEASUREMENTS AND WILL EMPLOY A UNIQUELY COMMUNITY-ORIENTED MEASUREMENT STRATEGY. CHEMICAL FINGERPRINTING WILL BE A CENTRAL ELEMENT OF THE PROJECT METHODOLOGY. CHEMICAL FINGERPRINTING WILL IMPROVE BOTH METHANE SOURCE ATTRIBUTION AND CO-EMITTED SPECIES INVENTORIES, OFTEN A HIGH PRIORITY CONCERN FOR COMMUNITY MEMBERS. THE PROJECT WILL WORK CLOSELY WITH COMMUNITY AND INDUSTRY ADVISORY GROUPS AND HEALTH SCIENCES PROFESSIONALS TO MAXIMIZE COMMUNITY BENEFITS OF THE STUDY.
