State mine inspector holds public meeting on JDI aggregate pit reclamation plan in Mohave County

The Office of the State Mine Inspector held a public meeting to accept comments on a proposed reclamation plan for the JDI Enterprises LLC aggregate pit, a 48.4-acre property about 5 miles east of Kingman in Mohave County.

The inspector's staff said the plan was found technically complete and eligible for the public meeting process. The plan covers about 23.1 acres of disturbance within the parcel, proposes a final pit depth of "32" (units not specified in the plan summary), and calls for final pit slopes of 3:1 (horizontal to vertical). Mining operations are anticipated to begin in late 2025 and continue for approximately 15 years, with reclamation of mining, processing and related areas to commence immediately upon cessation and to be completed within one year following cessation. The inspector's staff said that, if the plan is approved, financial assurance must be submitted to the office within 60 days and annual reports will be required.

Why it matters: Arizona law limits the mine inspector's reclamation jurisdiction to private aggregate mining disturbances exceeding five acres and requires plans to provide for stable post-mining land uses that meet engineering and erosion-control standards. The meeting provided a formal forum for adjacent landowners to ask questions about the plan and for the inspector's office to explain its role, timelines and under what narrow circumstances it may consider comments from other state officials.

Details from the meeting: Ken Overson, owner of W3 Planning and Research representing the owner, said the responsible party listed in the public notice is JDI Enterprises LLC and that owner outreach included mailed notices. "We sent a total of 41 notices out, notifying everybody within the half mile radius," Overson said; he added three of those notices were undeliverable using Mohave County Assessor addresses and one written comment received was supportive of the application.

Mine inspector staff explained the scope of the inspector's authority and the review process. The staff said the office first checks plans for administrative completeness, then sends technically complete plans to a qualified private consultant or engineer for technical review; if that review finds the plan technically complete, it proceeds to the public meeting stage. The staff warned that "the mine inspector is not a mine permitting agency and does not have jurisdiction regarding zoning, water, air, dust, traffic, and noise regulation," noting those concerns must be brought to the appropriate regulatory agencies. The staff also summarized statutory approval criteria, saying the inspector shall approve a reclamation plan if it provides for reclamation measures necessary to achieve stability and suitability for the post-mining land use objectives stated in the plan.

During public comment, Dr. Andrea Shields, a nearby property owner on West Wind Road, asked for clarification about the timeline and signage. "This is a 15 year proposal," Shields said, and asked whether operations were expected to run to the 15-year estimate or end sooner. Inspector staff replied that the 15 years in the plan is an estimate of how long mining is expected to continue; if mining ceases earlier, the law requires reclamation to begin within 12 months of cessation unless an extension is granted.

Shields also raised questions about a site sign that used the word "licensed" and mentioned a permit expiration date of 2035. Inspector staff and the owner's representative said the reclamation-plan public meeting is not a mine operating permit; mining operators are separately responsible for obtaining any required permits from agencies such as the Arizona Department of Environmental Quality (ADEQ) and the Mine Safety and Health Administration (MSHA). Overson said operators were updating signage to include ADEQ and MSHA permit numbers and that he would help connect residents with the on-site operator to provide further permit details.

The plan states the proposed post-mining land use is open space and that existing on-site residents will be maintained. Reclamation measures include regrading and scarifying disturbed areas to encourage natural revegetation and removing all mining equipment from the site.

The meeting record will include the agenda, any written comments submitted by the public and an electronic recording, the inspector's staff said. No formal vote or approval occurred during the meeting; the session closed after staff took a comment card from Dr. Shields and explained next steps in the review process.

The inspector's office encouraged residents with concerns about water, air or other non-reclamation matters to contact the appropriate regulatory agencies; the staff noted it may consider comments from the state geologist or elected officials when evaluating a reclamation plan.
