400.1 In the interest of the people within the jurisdiction of the NWCAA, it is the objective of the NWCAA to obtain and maintain the cleanest air possible, consistent with the highest and best practicable control technology.
400.2 In the areas where existing concentrations of air contaminants are lower than concentrations allowed by the standards enumerated below, degradation of the atmosphere should be minimized. The highest and best practicable control technology should be applied to all sources unless it is specifically determined that lesser technology is justified. Ambient air standards are set at levels which, according to latest knowledge, will not cause damage to health, plants or animals or degrade materials.
