Okla. Stat. tit. 45, § 45-771: Release of performance bond or deposit - Inspection and

evaluation of reclamation work.

Upon receipt of the notification and request, the Department

shall within thirty (30) days conduct an inspection and evaluation

of the reclamation work involved. Such evaluation shall consider,

among other things, the degree of difficulty to complete any

remaining reclamation, whether pollution of surface and subsurface

water is occurring, the probability of continuance or future

occurrence of such pollution, and the estimated cost of abating such

pollution. The Department shall notify the permittee in writing of

its decision to release or not to release all or part of the

performance bond or deposit within sixty (60) days from the filing

of the request, if no public hearing is held and if there has been a

public hearing held within thirty (30) days thereafter.
