This report summarizes the procedures used and the results obtained from the following phases of the North Carolina AQMA analysis: (1) analysis of baseline year (1973) point source emission inventories and projection of them to 1975, 1980, and 1985; (2) compilation of appropriate meteorological and climatological data for 1973, 1975, 1980, and 1985; (3) validation of ambient monitoring data for 1973; and (4) determination of the monitoring stations most representative of non-biased sampling with respect to local influences which cannot be defined by the Air Quality Display Model. The results of these activities were used in the dispersion modeling phase of the AQMA analysis, which is reported in Volume 3 of this study. Insofar as possible, EPA's guidelines for AQMA planning and analysis determined the methodologies used in the work described here. At times it proved necessary to devise other methodologies; a rationale for their use is provided.
