Financial assurances shall remain in effect until the County has determined that the reclamation plan has been completed as approved. Financial assurances may be made renewable for periods of at least one year. However, the failure of an operator to renew any financial assurance before its expiration date shall be considered a violation of this chapter. New or renewed financial assurances shall be submitted to the County prior to the expiration date of the existing financial assurances. (§ 1, Ord. 1191, eff. September 5, 1996)
