To ate , it is the purpose of this article to require the use of all available practical methods that are tecti ogically feasible and econornicaliy reasonable so as to reduce, prevent, and control air pollutlo ro hout the state of Colorado; to require the development of an air quality control program in ich the nefits of the air pollution control measures utilized bear a reasonable relationship to t economic, en · onmental , and energy impacts and other costs of such measures; and to maintai a cooperative progra between the state and local units of government. It is further declared th he prevention, abatement, nd control of air pollution in each portion ofthe state are matters of atewide concern and are affecte with a public interest and that the provisions of this article ar nacted in the exercise ofthe police po ers ofthis state for the purpose of protecting the healt , peace, safety, and general welfare ofthe pe le of this state
. The General Assemb urther recognizes that a current and accurate inventory actual emissions of air pollutants from sources is essential for the proper identification and designat1 of attainment and nonattainm t areas, the determination ofthe most cost effective regulatory strat pollution , the rgeting of regulatory efforts to ach ieve the greatest health and environme I benefits, and the a 1evement of a federally approved clean air program . In order to achieve the mos ccurate invent of air pollution sources possible, this article specifically provides incentives to achiev e

.mo accurate and complete inventory possible, and to provide for the most accurate enforcemen gram achievable based upon that inventory

Growth air pollution control programs toward solvThe Commission recognizes that e growth in the amount and comple · of air pollution in Colorado is brought about by, and incid to, population growth , mobility, increas ffluence , industrial development and changing socia alues in said state. The Commission belie s that the air pollution problem is likely to be aggravated a compounded by additional populatio growth , mobility, affluence , industrial development, and changin ocial values in the future , Iha re likely to result in serious potential danger to the public and the env1 nment. Therefore, th ommission intends to pursue solutions, in conjunction with other appropria agencies and in ests that have a direct interest and capability in solving a growing air pollution pr - lem(s) i elation to the broader environmental degradation problem
