[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (B) of this rule titled "Referenced materials."]

(A) The following definitions apply to this chapter:

(1) "PM10" means particulate matter with an aerodynamic diameter less than or equal to a nominal ten micrometers as measured by a reference method based on 40 CFR Part 50, Appendix J and designated in accordance with 40 CFR Part 53 or an equivalent method designated in 40 CFR Part 53.

(2) "PM 2.5 " means particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers as measured either by a reference method that is based on 40 CFR Part 50, Appendix L and designated in accordance with 40 CFR Part 53 or by an equivalent method designated in accordance with 40 CFR Part 53.

(3) "Primary ambient air quality standard" means the levels of air quality which are necessary, with an adequate margin of safety, to protect the public health.

(4) "Secondary ambient air quality standard" means the levels of air quality which are necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.

(B) Referenced materials. This chapter includes references to certain matter or materials.

The text of the referenced materials is not included in the rules contained in this chapter. Information on the availability of the referenced materials as well as the date of, and/or the particular edition or version of the material is included in this rule.
