Fugitive Dust Mitigation Amendments
HB 378 amends Utah's air quality laws to regulate dust emissions from specific industrial sites. It requires facilities like sand/gravel operations, excavation sites, and bulk material handling areas (over a quarter acre) to post visible public signage with facility details and contact information. The bill establishes a tiered annual fee system based on dust emissions: $750 for under 20 tons, $1,500 for 20-79 tons, $3,500 for 79-99 tons, and $4,500 for 99+ tons, starting in 2027 (with rules finalized by 2028). These fees apply to "aggregate operations" defined as facilities extracting or processing rock materials like sand, gravel, and stone, excluding agricultural sites or road salting. The bill repeals an outdated section and has no budget impact.

MODERATE
This bill updates the definition of 'aggregate' to explicitly exclude frac sand and clarifies that mineral salts are not subject to the new air compliance fee. It establishes a temporary fee schedule for aggregate operations based on emissions levels between 2027 and 2028, with permanent rules to follow later. Additionally, it expands the definition of 'fugitive dust facility' to include specific types of excavation and bulk material handling sites, requiring them to post signage with contact information.
Scope change
The scope of the air compliance fee was narrowed by excluding frac sand and mineral salts, while the scope of the fugitive dust signage requirement was expanded to include more types of construction and material handling sites.
DEFINITION
Added 'frac sand' and 'mineral salts' to the list of materials excluded from the definition of 'aggregate' for fee purposes.
REQUIREMENT
Required new fugitive dust facilities, including certain excavation and bulk material sites, to post informational signage with owner contact details.
TIMELINE
Set a temporary annual fee schedule for aggregate operations effective from July 1, 2027, to June 30, 2028, with fees ranging from $750 to $4,500 based on emissions.
Changed the effective date of the bill from May 6, 2026, to May 6, 2027, and updated the timestamp of the legislative record.
