Inspection of Mining Operations


Every permittee or the permittee’s agent shall always keep open to inspection by the Department or its agent the permit area as well as any books, records, papers or memoranda which are pertinent to the administration of this division, 1991 Oregon Laws, Chapter 735, or OAR 632, division 037.


The Department may access and copy any record and inspect any monitoring equipment or method of operation required for compliance with permit conditions for the protection of wildlife.


The permittee shall notify the Department 30 days prior to completion of construction of a chemical process mine. The Department shall inspect the construction site within ten days of completion of construction. The use of chemical processing solutions to dissolve metals from ore shall not commence until the Department notifies the permittee that the inspection is complete. Subsequent inspections shall be conducted at a frequency sufficient to ensure that the requirements of this division and any permit conditions designed to protect wildlife are being met. At a minimum, Department inspections shall be conducted on a semi-annual basis, beginning at the time of permit issuance.


When the Department determines on the basis of an inspection that any condition or practice existing at a chemical process mine is or can reasonably be expected to be harmful to wildlife, or that any permittee is in violation of any requirement of this division or any permit condition designed to protect wildlife, the Department shall document this finding in the inspection report and immediately notify the permittee and DOGAMI.


Copies of the inspection report shall be mailed in a timely fashion to:


The permittee, or the permittee’s designated agent or management personnel at the chemical process mine; and




Copies of any records, reports, inspection materials or information obtained during the Department inspection, except as otherwise provided by ORS 192.410 to 192.505 shall be made available to the public upon request.
