The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Your request for a diverter waiver is approved. The permit is for a nexv xvellbore segment of existing well Bl-15, Permit No. 74, API 50-029- 22878-00. Production should continue to be reported as a function of the original API number stated above. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice mav be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. · Chairman ~ BY ORDER OF THE COMMISSION df/enclosures cc: Department of Fish & Ga~ne, Habitat Section x~;'o encl.
