16.12.400 - General requirements.¶
A. All applicants, as a condition of approval of a permit issued under the provisions of this chapter, shall be required to execute an agreement and provide adequate security made payable to the county and the Department of Conservation guaranteeing without proof of loss compliance with the master mining plan, the conditions of the permit involved, and all of the requirements of this chapter and the Surface Mining and Reclamation Act.
B. Liability under any security required as a condition of approval of the permit shall continue until all reclamation work required by the approved master mining plan has been completed. In addition, the period of liability shall continue, and adequate security shall be retained to ensure the continued viability of the reclamation effort for a period of not less than five years, beginning with the last year of augmented seeding, fertilizing or other concluding work of the reclamation. This liability shall begin anew whenever additional reclamation is required on the mining site prior to bond release. The minimum security to be retained to guarantee the continued viability of the reclamation effort shall be as follows:
If the security guarantees the cost of all reclamation, ten percent of the aggregate cost of all reclamation; or
If the security posted was limited to each phase of the operation, the lesser of ten percent of the aggregate cost of all reclamation or the actual cost of reseeding or taking similar steps to ensure the continued viability of the reclamation.
The planning director may require greater security than the minimum if the probable cost of ensuring the long-term viability of the reclamation exceeds the above minimums.
C. If the county determines, following a public hearing, that an operator is financially incapable of performing reclamation in accordance with its approved reclamation plan or has abandoned its operation without reclamation, the county shall take such actions to forfeit the assurances as are described in subparagraphs (b) and (d) of Public Resources Code Section 2773.1.
(Ord. 1150 § 2 (part), 1998)
16.12.410 - Amount required—Initial.¶
A. The security required by Section 16.12.400 shall be in an amount equal to the estimated cost to the county if it were required to complete the reclamation required by the master mining plan, including any additional costs which may reasonably be expected to arise from public contracting requirements and further including an amount to account for inflationary factors, such amount not to exceed the inflationary increase associated with reclamation activities during the preceding five years. If the master mining plan submitted provides for mining in phases, the security may be limited to the cost of reclaiming the land impacted by the current phase of the mining operation if, upon application by the permittee, the planning commission or, on appeal, the board of supervisors, determines that:
The security of the county will not be impaired by accepting such lesser security,
Each phase of the mining operation will be completed prior to the next phase commencing,
Each phase of the mining excavation will impact on discrete parcels, and
Reclamation of a completed phase of the mining operation will commence simultaneously with the mining of the land involved in the succeeding phase.
B. Approval of any such lesser security shall be subject to the conditions that the security will equal or exceed the estimated cost of reclaiming the current phase of the permittee's mining operation and that, in addition to the aforementioned security, the approving body may at any time, after notice and hearing, require the permittee to increase the security to such an amount as represents the current estimated cost of reclaiming all land impacted by the permit to date, or all permits heretofore issued shall terminate.
(Ord. 1150 § 2 (part), 1998)
16.12.415 - Amount required—Annual adjustment/updating of reclamation cost estimates.¶
The amount of financial assurances for any one year shall be adjusted annually to account for the new land disturbed by surface mining operations, inflation, and reclamation of lands pursuant to the approved reclamation plan. The permittee shall annually file a revised cost estimate with the county on which said adjustment shall be based. Failure to file such an estimate shall be considered cause to revoke the permit after notice and hearing.
(Ord. 1150 § 2 (part), 1998)
16.12.420 - Amount required—Additions when.¶
A. If at any time the conditions under which a security was approved no longer prevail, the county may revoke the permit unless, within ninety days after notice is given, the permittee posts such sufficient or additional security as may be required by the planning director to ensure completion of reclamation.
B. If upon incapacity of a surety for any reason including, but not limited to, bankruptcy, insolvency or suspension or revocation of its license, and after receipt of a written demand by the county that additional security be provided, the permittee fails to provide additional security within sixty days, the permittee shall be in violation of the permit and mining operations shall immediately be discontinued until new and adequate security is provided.
(Ord. 1150 § 2 (part), 1998)
16.12.430 - Review process.¶
A. Within fifteen days of receipt of the agreement and associated security required under Section 16.12.400(A), the planning director shall review the materials provided for completeness. If the submittal is incomplete, the applicant shall be notified of the deficiencies found.
B. Upon a determination that the agreement and security package received is complete, the planning director shall distribute copies thereof to county counsel for review as to the acceptability of the documents contained therein.
C. Upon receipt of both an agreement and a security revised to reflect the comments received under subsection (B) of this section, the planning director shall submit copies of these documents along with the related costs estimates and the approved reclamation plan to the Department of Conservation for review. Pursuant to state law, forty-five days shall be provided for comment. The submittal shall contain a certification by the planning director that these financial assurances or assurance modifications meet all the requirements contained in the State Board Reclamation Regulations (Sections 3500 et seq. and 3700 et seq. of Title 14 of the California Code of Regulations).
D. The planning director and county counsel shall review the written comments received from the Department of Conservation and seek modification by the permittee of the agreement and/or security as necessary. The revised documents provided shall be returned to the Department of Conservation for final approval.
E. The board of supervisors shall review the approved agreement and security and either accept them in the submitted or a modified form or reject them.
F. Following acceptance of an agreement and the related security, the planning director shall forward copies of these documents to the operator, owner, and Department of Conservation.
