§ 292.12 General provisions; procedures. ( a ) *Approval of zoning ordinance and development plans.* ( 1 ) All validly adopted zoning ordinances and amendments thereto pertaining to the Shasta and Clair Engle-Lewiston Units may be submitted by the county of origin to the Secretary for written approval relative to their conformance with the applicable standards of §§ 292.11 to 292.13. Within 60 days following submission, the county will be notified of the Secretary's approval or disapproval of the zoning ordinances or amendments thereto. If more than 60 days are required, the county will be notified of the expected delay and of the additional time deemed necessary to reach a decision. The Secretary's approval shall remain effective so long as the zoning ordinances or amendments thereto remain in effect as approved.
( 2 ) Development plans pertaining to unimproved property within the Shasta and Clair Engle-Lewiston Units may be submitted by the owner to the Secretary for determination as to whether they conform with approved zoning ordinances and whether the planned use and development would serve the Act. Within 30 days following submission of such plans the Secretary will approve or disapprove the plans or, if more than 30 days are required, will notify the applicant of the expected delay and of the additional time deemed necessary.
( b ) *Amendment of ordinances.* Amendments of approved ordinances may be furnished in advance of their adoption to the Secretary for written decision as to their conformance with applicable standards of §§ 292.11 to 292.13.
( c ) *Variances or exceptions to application of ordinances.* ( 1 ) The Secretary shall be given written notice of any variance granted under, or any exception made to, the application of a zoning ordinance or amendment thereto approved by him.
( 2 ) The County, or private owners of improved property, may submit to the Secretary proposed variances or exceptions to the application of an approved zoning ordinance or amendment thereto for written advice as to whether the intended use will make the property subject to acquisition without the owner's consent. Within 30 days following his receipt of such a request, the Secretary will advise the interested party or parties as to his determination. If more than 30 days are required by the Secretary for such determination, he shall so notify the interested party or parties stating the additional time required and the reasons therefore.
( d ) *Certification of property.* Where improvements and land use of improved property conform with approved ordinances, or with approved variances from such ordinances, certification that the Secretary's authority to acquire the property without the owner's consent is suspended may be obtained by any party in interest upon request to the Secretary. Where the development and use of unimproved property for service to the public is approved by the Secretary, certification that the authority to acquire the property without the owner's consent is suspended may be issued to the owner.
( e ) *Effect of noncompliance.* Suspension of the Secretary's authority to acquire any improved property without the owner's consent will automatically cease if: ( 1 ) Such property is made the subject of variance or exception to any applicable zoning ordinance that does not conform to the applicable standard in the Secretary's regulation,
( 2 ) such property is put to a use which does not conform to any applicable zoning ordinance, or, as to property approved by the Secretary for development, a use which does not conform to the approved development plan or
( 3 ) the local zoning agency does not have in force a duly adopted, valid zoning ordinance that is approved by the Secretary in accordance with the standards of §§ 292.11 to 292.13.
( f ) *Nonconforming commercial or industrial uses.* Any existing commercial or industrial uses not in conformance with approved zoning ordinances shall be discontinued within 10 years from the date such ordinances are approved: *Provided, however,* That with the approval of the Secretary such 10-year period may be extended by the county for a prescribed period sufficient to allow the owner reasonable additional time to amortize investments made in the property before November 8, 1965.
