P. Importing of materials: The importin,q of materials, e..qu sand or topsoil, may be permitted if needed as part ur the mining activity. These imported materials could be used for preparinc~ the minin;] site for reclamation or blendin,cl with the on site materials to provide for a better fill or construction product that is then exported. The import of materials that are only to stockpiled, and are not related to the mininq activity, will not be permitted. _ 18.62.050 Asphalt and concrete batch plant; Asphalt and concrete batch plants, and related proce$_~ing facilities, may be permitted ;1' approved as part of the surface minina operations permit. The plants must be an incidental use to the on site minin,q activity. The plants shall only be located within the City'., Comprehensive Plan desionated mineral resource areas. 18.62-10 This pro~/ision does not apply to existinR plants that are operatin,q under pre existin~ - zonin.q authority. 18.62.05_60 Subsequent useRe~amai4e~ plan.

A. In conjunction with the mining permit a subsequent use of the mining site shall also be approved. The owner/operator shall submit a plan, in sufficient detail, to determine that the subsequent use of the mining site will be in conformance with the Comprehensive Plan and this Title. The owner/operator shall submit evidence that the amount of material to be removed is commensurate with the subsequent land use. B. The development of the subsequent use may precede the completion of thn minin.q In such cases the operations Dian and subsequent use plan shall be desi.qned to reduce conflict between the subsequent use and the operations of the mine. If tho subsequent use is developed in phases each phase must be able to stand on its own without reliance upon development of subsequent phases or future minin.q activity unless a phasin,q plan is approved by the Plann n.q Director. The phasin{:{ plan must minimize the need for future development or mininq necessary to complete the phase, provide for time frames to complete each phase includinq what is needed, e g extension of which utilities, streets, provision of parks, etc.. The Director may require financial security to ensure the completion of each phase. ............... ~ ............ ~' .......... ~ ..................... or , ,,.,.;~r,.,.,-,,i,, ,4;,-.,,,.;k, ,,,~.,,{ ,,,,,,,. ,,t-. .......... ;,.; .......

The proposal is consistent with the .qoals and policies of the Comprehensiv., Plan. .18.62 080 Years of o;)eration A. At the initial approval of an operations permit a master permit will be .qiven fo, the lifetime of the mineral resource at the mininq site. These mines must be located with;,, the City's Comprehensive plan desi.qnated mineral resource areas. Mines located outs!~ .the City's Comprehensive plan desi.qnated mineral resource areas may be .qranted a perm;( .for up to ten years and may be renewed but will be treated as a new application. B. Operations under a master permit must be reviewed by the Plannipq Director al .the end of each subsecluent ten years. The operator of the mine must submit to II~ 18.62-12 Planninq Director, at least 6 months prior to the end of each ten year period, evidence that the minin.q operation is in compliance with the conditions of the master permit and th,, standards contained within this chapter. This evidence shall include the submittal of th,, existin.cl topo.qraphy in a computer disk form that is compatible with the City's system. Tho operator shall also provide an estimate of the amount of material that has been removed, ;,,, estimate of when minin.q is to be complete, identification of any areas where minin.q been completed and whether restoration has be.qun or is anticipated to beqin. C. The master permit shall remain in effect if it is found the operations are i,, compliance with the conditions of the master permit, the standards contained within th;~; chapter, and there have been no siqnificant adverse impacts that have occurred that wet,, not previously identified and effectively miti.qated. D. If the Plannin.q Director determines that operations are not in compliance with th,', conditions of the master permit or the standards contained within this chapter, or that si.qnificant adverse imp=~.t$ have resulted from the operation and have not been miti.qated, then the Plannin.q Director shall so advise the minin.q operator in writin.q within ninety (90) days from receipt of the materials provided by the minin.q operator under sectiol', 18.62.080(B). If the Plannin.q Director determines that operations are not in complianc,, with the conditions of the master permit, the Planninq Director shall advise the minin;~ operator of any non-compliance and proposed corrections/revisions, includinq a time fram~'~ durin.q which such corrections/revisions are to be made. If si.qnificant adverse impacts hay,. occurred that were not previously identified and miti.qated, the Plannin.q Director shall advis., the minin.q operator of any required corrections/revisions to the master permit to include ~uch miti.qation. If new operation standards have been adopted pursuant to this chapter th.J, Planninq Director shall advise the minin.q operator of any required revisions to the maste, permit to reflect the new standards, if determined applicable and practical by the Plannir~!l Director, The minin.q operator shall have ninety (90) days from receipt of the Planninq Director',.; notice under section 18.62.080 (D) to make the required corrections/revisions or to appeal the Planninq Director's decision to the Hearinq Examiner pursuant Chapter 18.66 of thi~; Title. The Hearin.q Examiner may affirm, modify, or disaffirm the Plannin.q Director's_ determination. If the mining operator does not appeal the Plannin.q Director's determinatio, then the minin.q operator shall make the corrections/revisions proposed by the PlanninU Director and the master permit shall be modified to incorporate the revisions/corrections. 18.62-13 If the mininf:l operator does not make the corrections/revisions as required by the City the,, the Buildin,q Official shall proceed with enforcement action under Chapter 1.25 of th..
