Air pollution potentials vary within the jurisdiction of the NWCAA with varying degrees of social and economic development. These factors in combination with topographic and meteorological elements tend to accentuate or reduce emission effects.
The ambient air quality goals are defined for three areas within the jurisdiction of the NWCAA.
602.21 Area #1 – predominantly used for timber and agricultural crops, farming and recreation. Habitation and industry sparse.
602.22 Area #2 – dwelling units, small farms, commercial and office buildings and stores.
602.23 Area #3 – primarily light and heavy industry.
County and city planning agencies shall make available to the NWCAA the delineation of the zoning status within their area of jurisdiction.
