For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
"Area of regional significance"
means an area designated by the State Mining and Geology Board which is known to contain a deposit of minerals, the extraction of which is judged to be of prime importance in meeting future needs for minerals in a particular region of the state within which the minerals are located and which, if prematurely developed for alternate incompatible land uses, could result in the premature loss of minerals that are of more than local significance.
"Area of statewide significance"
means an area designated by the board which is known to contain a deposit of minerals, the extraction of which is judged to be of prime importance in meeting future needs for minerals in the state and which, if prematurely developed for alternate incompatible land uses, could result in the permanent loss of minerals that are of more than local or regional significance.
"Borrow pits"
means excavations created by the surface mining of rock, unconsolidated geologic deposits or soil to provide material (borrow) for fill elsewhere.
"Compatible land uses"
means land uses inherently compatible with mining and/or that require a minimum of public or private investment in structures, land improvements, and which may allow mining because of the relative economic value of the land and its improvements. Examples of such uses may include, but shall not be limited to, very low density residential, geographically extensive but low impact industrial, recreation, agricultural, silvicultural, grazing, and open space.
"Haul road"
means a road along which material is transported from the area of excavation to the processing plant or stockpile area of the surface mining operation.
"Idle"
means to curtail for a period of one year or more surface mining operations by more than 90% of the operations previous maximum annual mineral production, with the intent to resume those surface mining operations at a future date. (SMARA, Sec. 2727.1)
"Incompatible land uses"
means land uses inherently incompatible with mining and/or that require public or private investment in structures, land improvements, and landscaping and that may prevent mining because of the greater economic value of the land and its improvements. Examples of such uses may include, but shall not be limited to, high density residential, low density residential with high unit value, public facilities, geographically limited but impact intensive industrial, and commercial.
"Mined lands"
means the surface, subsurface, and ground water of an area in which surface mining operations will be, are being, or have been conducted, including private ways and roads appurtenant to any such area, land excavations, workings, mining waste, and areas in which structures, facilities, equipment, machines, tools or other materials or property which result from, or are used in, surface mining operations are located.
"Minerals"
means any naturally occurring chemical element or compound, or groups of elements and compounds formed from inorganic processes and organic substances, including, but not limited to, coal, peat, and bituminous rock, but excluding geothermal resources, natural gas, and petroleum.

"Reclamation"
means the combined process of land treatment that minimizes water degradation, air pollution, damage to aquatic or wildlife habitat, flooding, erosion, and other adverse effects from surface mining operations, including adverse surface effects incidental to underground mines, so that mined lands are reclaimed to a usable condition which is readily adaptable for alternate land uses and create no danger to public health or safety. The process may extend to affected lands surrounding mined lands, and may require backfilling, grading, resoiling, revegetation, soil compaction, stabilization, or other measures.
"Stream bed skimming"
means excavation of sand and gravel from stream bed deposits above the mean summer water level or stream bottom, whichever is higher.
"Surface mining operations"
means all or any part of the process involved in the mining of minerals on mined lands by removing overburden and mining directly from the mineral deposits, open pit mining of minerals naturally exposed, mining by the auger method, dredging and quarrying, or surface work incidental to an underground mine.

A. 
Applications for a conditional use permit or reclamation plan for surface mining or land reclamation projects shall be made on forms provided by the planning department. The application shall be filed in accordance with this chapter and procedures to be established by the community development director or the city manager's designee. The forms for reclamation plan applications shall require, at a minimum, each of the elements required by SMARA (2772-2773) and state regulations, and any other requirements deemed necessary to facilitate an expeditious and fair evaluation of the proposed reclamation plan.
B. 
Fifteen copies of a proposed reclamation plan shall be required for submittal in conjunction with all applications for conditional use permits for surface mining operations. For surface mining operations that are exempt from a conditional use permit pursuant to this chapter, the reclamation plan application shall include information concerning the mining operation that is required for processing the reclamation plan. All documentation for the reclamation plan shall be submitted to the city at one time. Applications shall include all required environmental review forms and information prescribed by the community development director or the city manager's designee.
C. 
The department will review the application package for completeness and shall, within 30 days after receipt, either accept the application as complete for the purpose of initiating permit processing or return the application as deficient. Resubmittal of the revised application shall start a new review time frame.
D. 
Within 30 days of acceptance of an application for a conditional use permit for surface mining operations and/or a reclamation plan as complete, the planning department shall notify the State Department of Conservation of the filing of the application(s). Whenever mining operations are proposed in the 100 year flood plain of any stream, as shown in Zone A of the Flood Insurance Rate Maps issued by the Federal Emergency Management Agency, and within one mile, upstream or downstream, of any state highway bridge, the planning department shall also notify the State Department of Transportation that the application has been received.

The planning commission shall hold at least one noticed public hearing on the conditional use permit and/or reclamation plan. The planning commission will make recommendation by resolution to the city council, who will ratify, amend, or deny the application.
H. 
1. 
Prior to final approval of a reclamation plan, financial assurances (as provided in this chapter), or any amendments to the reclamation plan or existing financial assurances, the planning commission shall certify to the State Department of Conservation that the reclamation plan and/or financial assurance complies with the applicable requirements of state law, and submit the plan, assurance, or amendments to the State Department of Conservation for review. The planning commission may conceptually approve the reclamation plan and financial assurance before submittal to the State Department of Conservation. If a conditional use permit is being processed concurrently with the reclamation plan, the planning commission may simultaneously also conceptually approve the conditional use permit. However, the planning commission may defer action on the conditional use permit until taking final action on the reclamation plan and financial assurances. If necessary to comply with permit processing deadlines, the planning commission may conditionally approve the conditional use permit with the condition that the planning department shall not issue the conditional use permit for the mining operations until cost estimates for financial assurances have been reviewed by the State Department of Conservation and final action has been taken on the reclamation plan and financial assurances.
2.

That the reclamation plan and potential use of reclaimed land pursuant to the plan are consistent with this chapter and the city's general plan and any applicable resource plan or element;
4. 
That the reclamation plan has been reviewed pursuant to CEQA and the city's environmental review guidelines, and all significant adverse impacts from reclamation of the surface mining operations are mitigated to the maximum extent feasible;
5. 
That the land and/or resources such as water bodies to be reclaimed will be restored to a condition that is compatible with and blends in with the surrounding natural environment, topography, and other resources, or that suitable off-site development will compensate for related disturbances to resource values;
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;
7. 
That a written response to the Director of Department of Conservation has been prepared, describing the disposition of major issues raised by the Director of Department of Conservation. Where the city's position is at variance with the recommendations and objections raised by the Director, the response shall address, in detail, why specific comments and suggestions were not accepted.
(Ord. 98-160)
A. 
In order to ensure that reclamation will proceed in accordance with the approved reclamation plan, the city shall require as a condition of approval one or more forms of security which will be released upon satisfactory performance. The applicant may post security in the form of a corporate surety bond, trust fund, irrevocable letter of credit from an accredited financial institution, a certificate of time deposit as part of an approved trust fund, or other method acceptable to the city and the State Mining and Geology Board as specified in statewide regulations adopted by the Mining and Geology Board, as specified in state regulations, 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 jointly payable to the city and the State Department of Conservation.
B. 
Financial assurances shall be required and be sufficient to ensure compliance with elements of the reclamation plan including, but not limited to, revegetation and landscaping requirements; restoration of aquatic or wildlife habitat; protection of archaeological sites; restoration of water bodies and water quality; slope stability and erosion and drainage control, disposal of hazardous materials; and other mitigation measures. The planning department shall monitor financial assurances for such elements of the plan.
C. 
Cost estimates for the financial assurance shall be submitted to the planning department for review and approval prior to the operator securing financial assurances. The community development director or the city manager's designee shall forward a copy of the cost estimates, together with any documentation received supporting the amount of the cost estimates, to the State Department of Conservation for review. If the State Department of Conservation does not comment within 45 days of receipt of these estimates, it shall be assumed that the cost estimates are adequate, unless the city has reason to determine that additional costs may be incurred. The planning director shall have the discretion to approve the financial assurance if it meets the requirements of this chapter, SMARA, and state regulations.
D. 
The amount of the financial assurances shall be based upon the estimated costs of reclamation for each year or phase stipulated in the reclamation plan, including any maintenance of reclaimed areas as may be required. Cost estimates shall be prepared by a California registered professional engineer and/or other qualified professionals retained by the operator and approved by the community development director or the city manager's designee. Financial assurances may be based upon estimates including, but not necessarily limited to the volume of earth moved (cubic yards) for each year or phase of reclamation. Financial assurances to ensure compliance with revegetation, restoration of water bodies, restoration of aquatic or wildlife habitat, and any other applicable element of the 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. A contingency factor of 10% shall be added to the cost of financial assurances.
E. 
In projecting the costs of financial assurances, it shall be assumed without prejudice or insinuation that the surface mining operation could be abandoned by an operator and, consequently, the city may need to contract with a third-party commercial company for reclamation of the site.
F. 
Where reclamation is accomplished in annual increments, the amount of financial assurances required for any one year shall be adjusted annually and shall be adequate to cover the full estimated costs for reclamation of any land projected to be in a disturbed condition from mining operations by the end of the following year. The estimated costs shall be the amount required to complete the reclamation on all areas that will not be subject to further disturbance, and to provide interim reclamation, as necessary, for any partially excavated areas in accordance with the reclamation plan. Financial assurances for each year shall be released upon successful completion of reclamation (including any maintenance required) of all areas that will not be subject to further disturbance and upon the operator filing additional financial assurances for the succeeding year. Financial assurances for all subsequent years of the operation shall be handled in the same manner.
G. 
Financial assurances for reclamation that is accomplished in multiple-year phases shall be handled in the same manner as described for annual reclamation.
(Ord. 98-160; Ord. 10-298 § 1)
A. 
Within 90 days of a surface mining operation becoming idle, the operator shall submit to the planning department a proposed interim management plan (IMP). The proposed IMP shall fully comply with the requirements of SMARA, including, but not limited to, all conditional use permit conditions, and shall provide measures the operator will implement to maintain the site in a stable condition, taking into consideration public health and safety. The proposed IMP shall be submitted on forms provided by the planning department, and shall be processed as an amendment to the reclamation plan. IMPs shall not be considered a project for the purpose of environmental review.
B. 
Financial assurances for idle operations shall be maintained as though the operation was active, or as otherwise approved through the idle mines IMP.
C. 
Upon receipt of a complete proposed IMP, the planning department shall forward the IMP to the State Department of Conservation for review. The IMP shall be submitted to the State Department of Conservation at least 30 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 or the city manager's designee 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 or the city manager's designee, to submit a revised IMP. The planning commission shall approve or deny the revised IMP within 60 days of receipt. If the planning 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.
(Ord. 98-160; Ord. 10-298 § 1)
Surface mining operators shall forward an annual surface mining report to the State Department of Conservation and to the city planning department on a date established by the State Department of Conservation, upon forms furnished by the State Mining and Geology Board. New mining operations shall file an initial surface mining report and any applicable filing fees with the State Department of Conservation within 30 days of permit approval, or before commencement of operations, whichever is sooner. Any applicable fees, together with a copy of the annual inspection report, shall be forwarded to the State Department of Conservation at the time of filing the annual surface mining report.
(Ord. 98-160)
A. 
The planning department shall arrange for inspection of a surface mining operation within six months of receipt of the annual report required in Section 7.96.120 to determine whether the surface mining operation is in compliance with the approved site approval and/or reclamation plan, approved financial assurances, and state regulations. In no event shall less than one inspection be conducted in any calendar year. The inspections may be made by a state-registered geologist, state-registered engineer, state-licensed landscape architect, or state-registered 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 planning director. All inspections shall be conducted using a form approved and provided by the State Mining and Geology Board.
B. 
The planning department shall notify the State Department of Conservation within 30 days of completion of the inspection that the inspection has been conducted, and shall forward a copy of the inspection notice and any supporting documentation to the mining operator. The operator shall be solely responsible for the reasonable cost of such inspection.
(Ord. 98-160)
The time limit for commencing a surface mining operation that is permitted pursuant to this section shall be as provided in Chapter 17.112.
(Ord. 98-160)
If the planning 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, the applicable permit and/or the reclamation plan, 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 Titles 15 and 16 of this code for revocation and/or abandonment of a conditional use permit which are not preempted by SMARA.
(Ord. 98-160)
Any person aggrieved by an act or determination of the planning department in the exercise of the authority granted herein shall have the right to appeal to the city council. An appeal shall be filed on forms provided, within 10 calendar days after the rendition, in writing, of the appealed decision.
(Ord. 98-160)
The city shall establish such fees as it deems necessary from time to time by resolution, to cover the reasonable costs incurred in implementing this chapter and the state regulations, including, but not limited to, processing of applications, annual reports, inspections, monitoring, enforcement and compliance. Such fees shall be paid by the operator, as required by the city, at the time of filing of the conditional use permit application, reclamation plan application, and at such other times as are determined by the city to be appropriate in order to ensure that all reasonable costs of implementing this chapter are borne by the mining operator.
(Ord. 98-160)
A. 
Mine development is encouraged in compatible areas before encroachment of conflicting uses. Mineral resource areas that have been classified by the State Department of Conservation's Division of Mines and Geology or designated by the State Mining and Geology Board, as well as existing surface mining operations that remain in compliance with the provisions of this chapter, shall be protected from intrusion by incompatible land uses that may impede or preclude mineral extraction or processing, to the extent possible for consistency with the Lathrop general plan.
B. 
In accordance with PRC 2762, the Lathrop general plan and resource maps will be updated to reflect mineral information (classification and/or designation reports) within 12 months of receipt from the State Mining and Geology Board of such information. Land use decisions within the city will be guided by information provided on the location of identified mineral resources of regional significance. Conservation and potential development of identified mineral resource areas will be considered and encouraged. Recordation on property titles of the presence of important mineral resources within the identified mineral resource areas may be encouraged as a condition of approval of any development project in the impacted area. Prior to approving a use that would otherwise be incompatible with mineral resource protection, conditions of approval may be applied to encroaching development projects to minimize potential conflicts.
