Environment (Air Quality)

HB 564 sets annual emissions limits for industrial facilities in four Utah counties (Davis, Salt Lake, Utah, and Weber) that are designated as "major nonattainment areas" for air pollution. The bill establishes specific yearly caps: 1,418 tons of PM2.5 (fine particulate matter) and 8,870 tons of nitrogen oxides. These limits apply directly to point sources like factories and power plants in those counties. The law takes effect on May 6, 2026, and does not appropriate new funding.

SB 234 amends Utah's rulemaking laws to require state agencies to base environmental health and waste management rules on scientific evidence and prevent them from creating rules stricter than federal standards. It defines key terms like "best available science" and "weight of scientific evidence," and specifies that rules affecting drinking water, air quality, hazardous waste, or solid waste handling must align with federal regulations. The bill directly affects Utah state agencies responsible for drafting and implementing environmental regulations, such as the Department of Environmental Quality. It does not appropriate funds or create new taxes, focusing solely on procedural requirements for rulemaking.

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 The bill repeals an outdated section and has no budget impact.
