a. Current road use not attributable to the mining and gravel operation.

b. Road use attributable to all uses including the mining and gravel operation at peak use identified in the Mining and Gravel Plan.

c. Include equivalent single axle load (ESAL) calculations for both current use and all uses including the projected peak use in the Mining and Gravel Plan.

2. Geotechnical Investigation. If requested by the county, the applicant shall retain a licensed geotechnical engineer to investigate and perform onsite testing for the existing road condition with the investigation's scope determined by the county engineer or designee, regardless of the road jurisdiction. All tests shall be performed in compliance with the road jurisdictions' permitting processes.

3. Road Improvements Required. If any roadway from the site to the public road network impacted by the mining and gravel operation is not engineered, designed, or constructed to withstand the projected peak use in the Mining and Gravel Plan, the applicant, owner, or operator shall improve the roads to the standard required by the county engineer or designee prior to commencing operations. Such improvements shall be engineered, designed, and constructed to withstand the expected 20-year life of the pavement, and meet any additional standards established by the county.

4. Road Damage Repairs Required. At the conclusion of operations, or at such earlier intervals as determined by the county, the owner and operator shall repair any damage to off-site roads caused by repetitive use attributable to the mining and gravel operation as determined in the sole discretion of the county engineer or designee.

5. Costs. The cost of all studies, investigations, road improvements, or road repairs are the sole responsibility of the owner and operator.

C. Limitations. All sites shall be subject to the Performance Standards for the Industrial zone found in County ORD 10-11-4. If the mining and gravel property is within 1,000 feet of any zone with any residential designation, and any dwelling has been constructed in any such zone, continuous noise monitoring is required. Noise monitoring should begin before operations commence to establish a pre-operations noise level. The owner-operator is only responsible for the noise generated on the mining and gravel property. Keep accurate and complete records of the noise monitoring, and provide such records to the county upon request. If standards in title 10, chapter 12 are more restrictive than the Performance Standards for the Industrial zone, the more restrictive standard applies over the more general. Noise from the mining and gravel operation, or from any temporary concrete mixing and batching plant, is limited to the approved hours of operation only. No mining or gravel zone or site shall be used for storage or dumping of junk or trash as defined in titles 4 and 10. Junk, trash, or debris is additionally defined as dead or dying vegetation, combustible material, landscape debris, or construction debris. Property in the mining and gravel zone shall not be used as a landfill or dump site.

D. Setback to Dwellings: All resource extraction, overburden, and storage areas shall have a minimum 100 foot setback from any dwelling or accessory dwelling in the Mining and Gravel zone or on any adjacent parcel zoned OST that has a current, existing, and valid CUP for an allowed use in the M-G zone, and a minimum 200 foot setback from any dwelling or accessory dwelling on any adjacent lot or parcel in any other zone. All crushers or concrete mixing and batching plant operations shall have a minimum radius setback of 400 feet from the operation to any dwelling or accessory dwelling on the property or on an adjacent lot or parcel.

E. Parking: One space for each employee on the shift with the highest number of employees, and one space for each vehicle used in association with the resource extraction. The designated parking spaces shall be separated from the active resource extraction areas and shown on the site plan. Designated parking spaces may move with phasing, but must remain separated from the active resource extraction areas.

F. Responsibility: The owner and authorized operator are jointly responsible for compliance with all laws and county requirements. All required applications, documents, plans, and performance assurances shall be submitted and approved by the county prior to commencement of construction or operation. Any change in the owner or authorized operator requires the express, written approval of the county, including assumption of the duties and responsibilities to perform operations in compliance with county approvals, and including new performance assurances.

G. Laws. All operations, emissions, water use, or discharges shall conform to Utah Department of Environmental Quality standards, as well as all local, state, and federal laws and regulations. (Ord. 2024-1276-O, 11-19-2024; amd. Ord. 2026-1321-O, 5-19-2026)

Ord. 2026-1321-O, 5-19-2026)

10-12-10: APPROVAL OF PLANS, ISSUANCE OF MINING AND GRAVEL PERMIT:

Once the Mining and Gravel Plan, the Rehabilitation and Reclamation Plan, and the performance assurance have been approved and accepted by the county, the applicant can obtain a Mining and Gravel Permit and a business license. Resource extraction shall not commence until all approvals, permits and licenses are obtained. The Mining and Gravel Permit and business license are valid for one year at a time. A yearly county inspection shall be conducted by the Community Development department, and if the operator is in compliance with the Plan, it can obtain a renewal without further action. If the owner or authorized operator are not in compliance with the Plan, they have 30 days to correct non-compliant items identified by the county at the yearly inspection and ask for a reinspection. If still not in compliance, the Plan and business license are automatically revoked and not renewed. The owner or authorized operator will be sent a Revocation Letter, notifying of the automatic revocation or nonrenewal by mail, deemed effective three business days after mailing. If the operations continue three business days after mailing of the Revocation Letter, the owner and authorized operator will be fined $500 a day until operations cease. If the owner or operator fail to cease operations after an additional ten business days, the fine will increase to $1,000 a day. The owner or authorized operator then would have to resubmit a Mining and Gravel Plan, obtain county approvals of the plan, and obtain a new Mining and Gravel Permit and business license. It is the owner or authorized operator's duty to request a yearly inspection a minimum of 30 days before permit expiration, and obtain all inspections necessary for yearly renewals. The Planning Commission may consider, and approve, modify, or deny the plans presented by the owner or authorized operator. Upon approval of plans by the county, a copy shall be placed on file in the community development department. (Ord. 2024-1276-O, 11-19-2024; amd. Ord. 2026-1321-O, 5-19-2026)

10-12-11: YEARLY INSPECTIONS AND COMPLIANCE:

The owner or authorized operator shall request and obtain a yearly site inspection from the Community Development Department or its designee and demonstrate compliance with the approved plans. This inspection is mandatory prior to yearly renewal of the Mining and Gravel Permit, or the business license. Additional inspections may be conducted by the county to ensure that the site complies with the conditions approved in the plans. Failure to comply with the inspection requirements, or failure to demonstrate compliance with the approved plans, may also result in other penalties provided in county ordinances. Applicant has a continuous duty to demonstrate that it intends to complete the resource extraction according to the Mining and Gravel Plan, and the Rehabilitation and Reclamation Plan, and in the time allotted in the approvals (Ord. 2024-1276-O, 11-19-2024; amd. Ord. 2026-1321-O, 5-19-2026)

10-12-12: EXPIRATION:

If the owner or authorized operator has not performed substantial onsite operations, including resource extraction for commercial renumeration and in commercial quantities, for a period of more than one year, all approved plans are automatically deemed expired. No resource extraction can resume without a new application and approvals under title 10, including compliance with new standards and regulations for resource extraction. (Ord. 2024-1276-O, 11-19-2024; amd. Ord. 2026-1321-O, 5-19-2026)

10-12-13: EFFECT OF THE ZONE, EXISTING CONDITIONAL USE PERMITS:

All mining and gravel operations approved as a conditional use permit or otherwise, prior to adoption of the title 10, chapter 12, Mining and Gravel zone, may continue to operate in the zone in which they were approved, and strictly under the conditions of the approved conditional use permit. Any substantial change to an existing conditional use permit, that was approved prior to adoption of the Mining and Gravel zone, requires compliance with the provisions herein, chapter 12, sections 7 through 10. The Community Development director or designee determines, in the county's sole discretion, if the proposed changes to the conditional use permit are minor or substantial. If a pre-existing conditional use permit has expired or terminated, the applicant shall seek and obtain a zone change to Mining and Gravel, and shall seek and obtain a Mining and Gravel Permit, before recommencing or continuing resource extraction.
