The Ozone Transport Assessment Group (OTAG) is a national workgroup formed by the U.S. Environmental Protection Agency (USEPA) and the Environmental Council of States (ECOS) to assess and resolve issues relevant to ozone transport. To successfully perform photochemical modeling required the development of high quality base and future year emission inputs. The base year emission inventory data included a 1990 average summer day emission inventory of VOC, NO, and CO covering all stationary point and area sources throughout the entire OTAG modeling domain. Mobile emission estimates were also developed for the entire domain, based upon inputs collected from the States, USEPA, and the Lake Michigan Air Directors Consortium (LADCO). This inventory represented the integration of all emissions data supplied by the States with USEPA`s Regional Interim Emission Inventory (the Interim Inventory). The future year emission inventory data included growth and control factors required to project emissions to 2007 under a base (Base I) and more stringent control scenarios. The Base I control scenario included the integration of State-supplied growth and control factors with default growth and control factors which model CAA mandated controls, as well as controls designated in States` 15% Plans. Special methodologies were developed to project emissions from electric utilities and on-road mobile sources.
