Title 19 — Development Code

§ 19.58

Twentynine Palms Zoning Code · 2026-06 edition · updated 2026-07-25 · Twentynine Palms

19.58.010 - Purpose

The City recognizes that the extraction of minerals is essential to the continued economic well-being of the City and to the needs of society and that the reclamation of mined lands is necessary to prevent or minimize adverse effects on the environment as well as protect public health and safety. Therefore, the purpose of this Chapter is to regulate surface mining operations as authorized by California's Surface Mining and Reclamation Act of 1975 (Public Resources Code Section 2710 et seq.) as amended, hereinafter referred to as SMARA; Public Resources Code Section 2207; and the California Code of Regulations adopted pursuant thereto (14 California Code of Regulations, Section 3500 et seq.), hereinafter referred to as State Regulations, to ensure all the following:

A.

The adverse environmental and other effects of surface mining will be prevented or minimized, and that mined lands will be reclaimed to usable condition to provide for the beneficial, sustainable, long-term productive use of the mined and reclaimed lands.

B.

The production and conservation of minerals are encouraged while avoiding or minimizing adverse effects on the environment, including but not limited to geologic subsidence, air pollution, water quality degradation, damage to wildlife resources, flooding, erosion, degradation of scenic quality, and noise pollution.

C.

The reclamation of mined lands will be carried out in such a way that the continued mining of valuable minerals will not be precluded.

D.

Residual hazards to the public health and safety will be reduced.

As the State Regulations may be amended from time to time, they are made a part of this Chapter by reference with the same force and effect as if the provisions therein were specifically and fully set out herein, excepting that when the provisions of this Chapter are more restrictive than correlative State provisions, this Chapter shall prevail.

19.58.020 - Applicability

A.

A Surface Mining and Land Reclamation Permit shall be required for all surface mining operations, and for the expansion or substantial change of any surface mining operation.

6.

That the Reclamation Plan will restore the mined lands to a usable condition which is readily adaptable for alternative land uses consistent with the General Plan and applicable resource plan.

19.58.130 - Phasing of Reclamation

Reclamation activities shall be phased with respect to the mining operation and shall be initiated at the earliest possible time on those portions of the mined lands that will not be subject to further disturbance (see Section 19.58.170 Interim Management Plan for Idle Mining Operations). Interim reclamation may also be required for mined lands that have been disturbed and that may be disturbed again in future operations. Reclamation may be done on an annual basis, in stages compatible with continuing operations, or on completion of all excavation, removal or fill, as approved by the City. Each phase of reclamation shall be specifically described in the Reclamation Plan and shall include:

A.

The beginning and expected ending dates for each phase.

B.

All reclamation activities required.

C.

Criteria for measuring completion of specific reclamation activities.

D.

Estimated costs as provided under Section 19.58.140 (Financial Assurances for Reclamation Plans).

19.58.140 - Financial Assurances for Reclamation Plans

A.

To ensure that reclamation will proceed in accordance with the approved Reclamation Plan, the City shall require, as a condition of approval, security which will be released upon satisfactory performance. The applicant may post security in the form of a surety bond, trust fund, irrevocable letter of credit from an accredited financial institution, trust funds or other method acceptable to the City and the State Mining and Geology Board as specified in statewide regulations adopted by the State Mining and Geology Board, and which the City reasonably determines are adequate to perform reclamation in accordance with the surface mining operation's approved Reclamation Plan. Financial assurances shall be made payable to the City and the Department of Conservation (Public Resources Code Section 2773.1(a)(4)).

B.

Financial assurances will be required to ensure compliance with elements of the Reclamation Plan including, but not limited to, revegetation and landscaping requirements; restoration of aquatic or wildlife habitat; restoration of waterbodies and water quality; slope stability, erosion and drainage control; disposal of hazardous materials; and other mitigation measures. Financial assurances for such elements of the plan shall be monitored by the Community Development Director.

C.

The amount of the financial assurances shall be based upon the estimated costs of reclamation for the years or phases stipulated in the approved Reclamation Plan, including any maintenance of reclaimed areas as may be required, subject to adjustment for the actual amount required to reclaim lands disturbed by surface mining activities since January 1, 1976, and new lands to be disturbed by surface mining activities in the upcoming year, as provided in Subsection F, below. Cost estimates shall be prepared by a licensed engineer and/or other qualified professionals retained by the operator and approved by the Community Development Director. The estimated amount of the financial assurance shall be based on an analysis of physical activities necessary to implement the approved Reclamation Plan, the unit costs for each of these activities, the number of units of each of these activities, and the actual administrative costs. Financial assurances to ensure compliance with revegetation, restoration of waterbodies, restoration of aquatic or wildlife habitat, and any other applicable element of the approved Reclamation Plan shall be based upon cost estimates that include, but may not be limited to, labor equipment, materials, mobilization of equipment, administration and reasonable profit by a commercial operator other than the permittee.

D.

In projecting the costs of financial assurances, it shall be assumed without prejudice or insinuation that the surface mining operation could be abandoned by the operator and, consequently, the City or state may need to contract with a third party commercial company for reclamation of the site.

E.

The financial assurances shall remain in effect for the duration of the surface mining operation and any additional period until reclamation is completed, including any maintenance required (Public Resources Code Section 2773.1(a)(2)). If the mining operation is sold, or ownership is otherwise transferred, the existing financial assurances shall remain in full force and shall not be released by the lead agency until new financial assurances are secured by the new owner and have been approved by the lead agency

(Public Resources Code, Section 2773.1(c)). Financial assurances shall be released upon written notifications by the lead agency, which shall be forwarded to the operator and the Director of the Department of Conservation, that the reclamation has been completed in conformance with reclamation (Public Resources Code Section 2773.1(c)).

F.

The amount of financial assurances required of a surface mining operation for any one calendar year shall be adjusted annually to account for new lands disturbed by surface mining operations, inflation, and reclamation of lands accomplished in accordance with the approved Reclamation Plan (Public Resources

Code, Section 2773.1(a)(3)). The financial assurances shall include estimates to cover estimated reclamation for existing conditions and anticipated activities during the upcoming year, excepting that the permittee may not claim credit for reclamation scheduled for completion during the coming year.

G.

Revisions to financial assurances shall be submitted to the Community Development Director each year prior to the anniversary date for approval of the financial assurances. The financial assurance shall cover the cost of existing disturbance and anticipated activities for the next calendar year, including any required interim reclamation. If revisions to the financial assurances are not required, the operator shall submit a written statement indicating why revisions are not required.

19.58.150 - Periodic Review

As a condition of approval of a Surface Mining and Land Reclamation Permit, an annual review shall be conducted to evaluate and ensure compliance with the approved permit including all applicable conditions imposed thereon by the City Council. The annual review shall be conducted by the Community Development Director, and if it appears that the permittee is not in full compliance therewith, a hearing may be noticed by the Community Development Director for revocation or other appropriate action by the City Council, using the general procedures of this Development Code (Section 19.28.100 Public Hearing and Public Notice), and in compliance with all applicable provisions of state law, including SMARA.

19.58.160 - Inspections

The Community Development Director shall arrange for inspection of a surface mining operation within six months of receipt of the annual report required in Section 19.58.090 (Annual Reports), to determine whether the surface mining operation is in compliance with the approved Surface Mining and Land Reclamation Permit, approved financial assurances, and State Regulations [Public Resources Code, Section 2774(b)]. In no event shall less than one inspection be conducted in any calendar year. Said inspections may be made by a state-registered geologist, state-registered civil engineer, state-licensed landscape architect, or stateregistered forester who is experienced in land reclamation and who has not been employed by the mining operation in any capacity during the previous 12 months, or other qualified specialists, as selected by the Community Development Director and as retained by City Council. All inspections shall be conducted using a form approved and provided by the State Mining and Geology Board. The Community Development Director shall notify the Director of Department of Conservation within 30 days of completion of the

inspection that said inspection has been conducted, and shall forward a copy of said inspection notice and any supporting documentation to the mining operator. The operator shall be solely responsible for the reasonable cost of such inspection.

19.58.170 - Interim Management Plan for Idle Mining Operations

A.

Within 90 days of a surface mining operation becoming idle, as defined in Section 19.06.090 of this Code, the operator shall submit to the Community Development Director a proposed Interim Management Plan (IMP). The proposed IMP shall fully comply with the requirements of Public Resources Code Section 2770(h), and shall provide measures the operator will implement to maintain the site in compliance with

SMARA, including, but not limited to, all conditions of the Surface Mining and Land Reclamation Permit. The proposed IMP shall be processed as an amendment to the Reclamation Plan and shall not be considered a project for the purposes of environmental review.

B.

Financial assurances for idle operations shall be continued as addressed in the Reclamation Plan or as otherwise approved through the proposed IMP of the idle mine.

C.

Upon receipt of a complete proposed IMP, the Community Development Director shall forward the IMP to the Department of Conservation for review. The IMP shall be submitted to the Department of Conservation at least 45 days prior to approval by the Planning Commission.

D.

Within 60 days of receipt of the proposed IMP, or a longer period mutually agreed upon by the Community Development Director and the operator, the Planning Commission shall review and approve or deny the IMP in accordance with this Chapter. The operator shall have 30 days or a longer period mutually agreed upon by the operator and the Community Development Director to submit a revised IMP. The Planning Commission shall approve or deny the revised IMP within 60 days of receipt. If the Commission denies the revised IMP, the operator may appeal that action to the City Council.

E.

The IMP may remain in effect for a period not to exceed five years, at which time the Planning Commission may renew the IMP for another period not to exceed five years or require the surface mining operator to commence reclamation in accordance with its approved Reclamation Plan.

19.58.180 - Violations and Penalties

If the Community Development Director, based upon an annual inspection or otherwise confirmed by an inspection of the mining operation, determines that a surface mining operation is not in compliance with this Chapter and/or the Surface Mining and Land Reclamation Permit, the City shall follow the procedures set forth in Public Resources Code Sections 2774.1 and 2774.2 concerning violations and penalties, as well as those provisions of this Development Code for revocation and/or abandonment of a Surface Mining and Land Reclamation Permit which are not preempted by SMARA.
