Lone Pine Canyon Road Quarry proposes to implement a Reclamation Plan

[Wrightwood]

PROJECT DESCRIPTION:
Summary
The Lone Pine Canyon Road Quarry proposes to implement a Reclamation Plan (Project)
following mining operations at Lone Pine Canyon Road Quarry, an existing vested mine for
limestone located on approximately 285-acre (including setbacks) of a 420-acre site. The site
consists of three non-contiguous parcels:

APN 0356-231-02: total of 320 acres; mining and reclamation occurs on: 198 acres
APN 0356-241-02; total of 12.85 acres; mining and reclamation occurs on: 10.7 acres
APN 0356-241-03; total of 90 acres; mining and reclamation occurs on: 70.1 acres

The project involves the parcels APNs 0356-231-02, 0356-241-02, and -03 (referred to herein
collectively as Project Site). The site is located near the unincorporated area of San Bernardino
County known as Wrightwood.

Is there a public comment period? I have some major concerns including truck traffic and air quality. I grew up near the cement plant in Riverside and the silica dust from the mining operations caused major health issues.

Planning Staff and the Project Proponent will attend the Wrightwood Fire Safe Council meeting on April 21, 2026. The project proponent has a 10-15 min presentation they would like to present and will be prepared to answer questions. Additionally, the Environmental Document is currently being circulated for review and public comment. The deadline for public comments on the CEQA document is April 22, 2026 and the public can comment by emailing me at Derek.Newland@lus.sbcounty.gov

Wrightwood Fire Safe Council meeting

Is there a public comment period? I have some major concerns including truck traffic and air quality. I grew up near the cement plant in Riverside and the silica dust from the mining operations caused major health issues.

As I read the documents, the mining claim is permanent, and the County can't stop it directly.

This is about the mitigation/remediation plan.  If that can be stopped, then there is a chance they can't mine.

The remediation plan runs through the year 2175.

Yes, I read through it last night and saw that they have a vested interest in the mine. However, if it's been a while since there was active mining, it could be considered abandoned. Then they would need entirely new permits. Does anyone know when that mine was last worked? Someone suggested checking with the Wrightwood Historical Society. Anyone have a contact for them? I'll be out of town all day today or I would swing by the museum.

The vested mining rights were approved by the SB County Planning Commission in a hearing on 3/17/2019.  This part of the project is for the required "reclamation" aspect of the mining impact on the surrounding area. As I read it (do correct), the Mitigated Negative Declaration does one address the issues raised by the mining part of this project - it only deals with the reclamation aspects of it. Therefore, the impacts as described are diminimus compared to those of the mining operation and not addressed in the Negative Dec.
You'd have to go back to the Planning Commission docs from 2019 to see the scale of the operation proposed and what mitigations were required by the County.

Here’s 2 links to county proceedings in Feb/Mar 2019. I’m not seeing a 3/17/19 meeting.

The last date was 3/7 - not 3/17. Thanks

I note that staff recommended the determination of vested mining rights be denied and recommended a Conditional Use Permit.  The 3/7/19 memo laid out the determinations for approval, denial, or referral to the Supervisors.  The minutes of the meeting would summarize the action taken.

Ok. Here’s the link to the PC meeting notes where vested status was approved.

There's a meeting tomorrow at the CSD - Tuesday, April 21 at 6:00 PM

And a petition

The CSD does have a meeting tomorrow night at 6:00 but it's not the same meeting where this mining issue will be discussed. I believe the CSD is meeting at the old firehouse. The Wrightwood Fire Safe Council is meeting at the community building at 6:00 p.m. tonight and that's where the information will be reviewed.
