This document describes the collection of nonmethane hydrocarbon transport data to be used in Level III: EKMA-OZIPP analysis for Louisville, Kentucky and Nashville, Tennessee. Ambient air samples were collected during September, 1980, at sites normally upwind of these cities. Integrated samples were collected at each site from 6:00 am to 9:00 am daily for two weeks. Samples were collected in Tedlar bags then transferred to stainless steel canisters for shipment and analysis. Cryogenic trapping with liquid oxygen was used to concentrate the hydrocarbon species and to separate methane and nonmethane hydrocarbons. Nonmethane hydrocarbons were thermally desorbed in a gas chromatograph and quantitated with a flame ionization detector (FID). This method was thoroughly tested and data in support of it are presented within the report. Nonmethane hydrocarbon (NMHC) concentrations (6-9 am average) near the upwind monitoring site for Louisville, Kentucky, ranged from 0.11 to 0.96 ppmv-C with a mean value of 0.30 ppmv-C and a median of 0.22 ppmv-C. NMHC concentrations near the upwind monitoring site for Nashville, Tennesee ranged from 0.06 to 0.34 ppmv-C with a mean value of 0.12 ppmv-C and a median of 0.09 ppmv-C.
