401 KAR 53:005. General provisions

      Section 1. Purpose and Intention. (1) The purpose of the primary ambient air quality standards is to define levels of air quality which the cabinet judges are necessary, with an adequate margin of safety, to protect the public health. Secondary ambient air quality standards define levels of air quality which the cabinet judges necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.

      (2) In the establishment of these standards, it is the intention of the cabinet to prohibit further significant and avoidable deterioration of air quality in areas where air quality presently exists which is numerically equal to or less than the standards expressed herein.

      (3) Except as provided in 401 KAR 51:010, no person shall violate, or interfere with the attainment or maintenance of, ambient air quality standards as specified in 401 KAR 53:010.

 

      Section 2. Applicability. (1) The primary and secondary ambient air quality standards stated in 401 KAR 53:010 shall apply at any single point location.

      (2) The secondary standard for odor shall be applicable only when the cabinet receives a complaint with respect to odors from a source.

      (10) "One (1) month average" means an average determined on the basis of any consecutive thirty (30) day interval.

      (11) "Maximum" means an ambient air quality standard which shall not be exceeded more than once per year providing that the averages exceeding the standard do not contain any common hourly data points.

      (12) "Odor" means the property of an air contaminant that can be detected by the sense of smell.
