Sections in this part
§ 18.48.010. Purpose and Applicability. ¶
A. Purpose. The purpose of this chapter is to regulate surface mining and reclamation operations consistent with the County General Plan and State Surface Mining and Reclamation Act of 1975 (and all subsequent amendments) and with the State Mining and Reclamation Policy specified in Chapter 8 of Title 14 of the California Code of Regulations. The provisions of SMARA (PRC Section 2710 et seq.), PRC Section 2207, and State regulations CCR 3500 et seq., as those provisions and regulations may be amended from time to time, are made a part of this chapter by reference with the same force and effect as if the provisions were specifically and fully set out, excepting that when the provisions of this chapter are more restrictive than correlative State provisions, this chapter shall prevail.
B. Applicability. The requirements of this chapter are applicable to any surface mining operation in unincorporated Merced County, except those operations specifically exempted by Sections 2714 or 2776 of the California Public Resources Code.
(Ord. 1976 § 2, 2019)

§ 18.48.070. Enforcement. ¶
SMARA has designated the County as being responsible for enforcing violations of SMARA and this chapter (Surface Mining and Reclamation). The Department may use this chapter to enforce mining and reclamation violations. The Director may also apply administrative penalties as described in SMARA and in this section.
A. Financial Assurance Forfeiture. SMARA has designated the County with the primary responsibility to seek forfeiture of financial assurances and to reclaim mines in the County. The procedure for financial assurance forfeiture is as follows:
The Commission shall hold a public hearing resulting in a determination that the operator:
a. Is financially incapable of performing the reclamation in compliance with the reclamation plan; or
b. Has abandoned the surface mining operation without completing the reclamation.
The Department shall notify the operator by certified mail of appropriate action to forfeit the financial assurance and specify reasons for so doing.
The Department shall allow the operator 60 days to commence or cause the commencement of reclamation in compliance with the approved reclamation plan and require that reclamation be completed within the time limits specified in the approved reclamation plan or some other time mutually agreed upon by the County or the State geologist and the operator.
The Department shall proceed to take appropriate action to require forfeiture of the financial assurances if the operator does not substantially comply with paragraph 3 of this subsection.
The Department shall use the proceeds from the forfeited financial assurances to conduct and complete reclamation as practicable in compliance with the approved reclamation plan.
B. Administrative Penalties. The County is primarily responsible for assessing administrative penalties on mining operations out of compliance with SMARA consistent with the following procedure:
If a violation extends beyond 30 days of the first written notice to the operator, the Department may issue an order for administrative penalty by certified mail for an administrative hearing scheduled 30 days or more after the date of the order. The order will state all violations and require the operator to comply with SMARA and this chapter but may only take effect after the hearing. The hearing notice is limited to the project site.
The Director shall also consider and may impose an administrative penalty not exceeding $5,000.00 per day assessed from the original date of noncompliance. Penalties shall be used for no purpose other than to cover the reasonable costs of enforcement. The Director shall take into consideration the nature, circumstances, extent, and gravity of the violation, any prior history of violations, degree of culpability, economic savings, if any, resulting from the violation, and any other matters justice may require.
from the original date of noncompliance. Penalties shall be used for no purpose other than to cover the reasonable costs of enforcement. The Director shall take into consideration the nature, circumstances, extent, and gravity of the violation, any prior history of violations, degree of culpability, economic savings, if any, resulting from the violation, and any other matters justice may require.
A subsequent order issued by the Department and sent by certified mail is necessary to notify the operator of administrative penalties for repeated violations. Payment of any administrative penalty shall be made within 30 days of issuance of the order, unless the operator petitions the Board to review the order of administrative penalty.
In case of a petitioned order, the Board shall notify the operator by certified mail whether or not the Board will review the order setting the administrative penalty. If the Board reviews the order, the Board shall establish the complete record of evidence to implement the policies of SMARA. If the Board upholds or issues an order, the Board shall notify the operator by personal service or certified mail of the order.
Any petitioned order or Board order shall become effective unless the operator petitions the Superi-or Court within 30 days following either the Board order or Board denial to review the petitioned order.
