To proceed with development of an air management plan that incorporates programs to manage changes in air quality, growth in the number of sources of air pollution, pollution control strategies and other important factors, a comprehensive inventory of existing air emissions is required. Inventories of all major point, mobile and area sources of air emissions in the Lower Mainland was prepared by the GVRD and various consultants in 1987 and 1988 for 1985. The results for the GVRD are summarized in this appendix to establish a baseline for interpreting existing air quality and to form a basis for forecasting the quantity of each pollutant that might be emitted in future years.

The first appendix summarizes the climatology of the Lower Fraser Valley, especially the GVRD, with emphasis on those aspects affecting air pollution potential. First it considers the general climatological context of the region then the special local or mesoscale characteristics that lead to within-region climatic variability. The historical and current ambient air quality and the likely future air quality in the GVRD are discussed in the second appendix. In addition to the data collected routinely in the monitoring network, air quality information derived from special studies is included in this summary. The third appendix compares air quality regulations which are applicable to GVRD with corresponding regulations for other Canadian jurisdictions, as well as selected U.S. jurisdictions. In the fourth and final appendix, various modelling aspects of the Air Management Plan are addressed. Since one of the most important current air quality issues in the GVRD is related to photochemical oxidants, the role of photochemical models in the Air Management Plan has received the greatest emphasis. Other modelling requirements are addressed also. A review of more complex photochemical models is presented, and recommendations for the use of such models in the GVRD are discussed.
