Millcreek officials have officially filed an appeal against an air quality permit granted to Granite Construction for a new quarry in Parleys Canyon. The city is seeking to block the project over concerns regarding potential dust and air quality degradation for local residents.
Why it matters
The appeal aims to address municipal health concerns regarding the impact of mining activity on local air quality. City leaders are pushing for a formal legal review to ensure that the proposed quarry does not negatively affect the surrounding environment.
The proposed quarry site is situated off exit 132 in Parleys Canyon. Granite Construction has stated that the facility expects to remain below minor air quality emissions thresholds using emission-friendly equipment.
