The report is a quality maintenance plan for the Baltimore Air Quality Maintenance Study Area, which is coterminous with the Metropolitan Baltimore Air Quality Control Region. The report contains a trial analysis of whether the national ambient air quality standards for particulate matter, sulfur dioxide, photochemical oxidants, and nitrogen dioxide will be maintained for the ten year period 1975-1985; a trial plan to maintain the standards which are not expected to be maintained over that period; and a description of the method used to develop the trial plan.
