(1) A person may not drill or use a well without first obtaining a permit from the State Department of Geology and Mineral Industries and posting any bond that may be required pursuant to ORS 520.095 (1). Drilling must be completed within one year from the date the permit is issued unless an extension is granted under subsection (2) of this section. When drilling has been completed, the well must be maintained under a permit until it is properly plugged and the site is reclaimed.

(3) A permittee maintaining or operating a well shall provide the department with an annual report on a form provided by the department. Subject to the determinations in subsection (4) of this section, a permittee shall renew the permit for a well by paying the fee established under ORS 520.017.
