(1) R307-309 applies to all new or existing sources of fugitive dust one-quarter acre or greater and any sources of fugitive emissions located in PM10 or PM2.5 nonattainment or maintenance plan areas as defined in 40 CFR 81.345 (July 1, 2011). Collectively, the PM10 and PM2.5 nonattainment and maintenance plan areas are geographically defined as all regions of Salt Lake and Davis counties; all portions of the Cache Valley; all regions in Weber County west of the Wasatch mountain range; all regions of Utah County; in Box Elder County, from the Wasatch mountain range west to the Promontory mountain range and south of Portage; and in Tooele County, from the northernmost part of the Oquirrh mountain range to the northern most part of the Stansbury mountain range and north of Route 199.

(2) Exemptions.

(a) Agriculturally derived fugitive dust sources, including agricultural or horticultural activities specified in 19-2-114 (1)-(3) are exempt from the provisions of R307-309.

(3) Opacity in R307-309-5(1) shall not apply when the wind speed exceeds 25 miles per hour if the owner or operator has implemented, and continues to implement, the accepted fugitive dust control plan in R307-309-6 and administers one or more of the following contingency measures:

(a) Pre-event watering;

(b) Hourly watering;

(c) Additional chemical stabilization;
