This webpage lists Shell's various Notice of Intent (NOI) to Discharge into Camden Bay, of the Beaufort Sea in the Arctic Ocean, under conditions of the NPDES General Permit AKG280000. The drill site is named "Sivulliq N" in the listed NOI. The location of Sivulliq N is off Alaska'a North Coast about 15 miles north of Flaxman Island. Shell identifies this site as in the area of Flaxman Island Lease Block 6558.

Environmental Protection Agency (EPA) Region 10 received from Shell, between 2009 and 2011 for Sivulliq N, a series of NOI for oil drilling waste discharge into the Beaufort Sea.

Sivulliq N drill site in the Beaufort Sea
Original NOI for Sivulliq N submitted to EPA by Shell (Dated May 7, 2009). Public comment showed that the original May 2009 NOI was inadequate.

Attachment A to the original NOI was released as Shell's response to public comments (dated November 30, 2009). This amended original NOI included the Drilling Fluids Plan (DFP) as required by the Camden Bay Exploration Plan (CBEP). Limited, revised and additional facility line drawings of the some of the 14 discharge waste streams was provided but without waste flow balancing as required by NPDES General Permit AKG280000. The EPA approved the NOI with omissions but the BP oil spill (BPOS) in the Gulf of Mexico caused a suspension of drilling activities in the Arctic Ocean for the summer/fall of 2010.

Revised NOI for 2011 Sivulliq N submitted to EPA by Shell (dated October 12, 2010). This revised NOI included changes to the drilling start date (to July 2011), changes to the Drilling Fluids Plan (DFP) and omits other environmental related reports. Limited and revised facility line drawings of the some of the 14 discharge waste streams was provided but without waste flow balancing as required by NPDES General Permit AKG280000. The EPA approved the NOI with omissions but delays in the Air Permit for the drilling project caused a cancelling of drilling activities in the Beaufort Sea for the summer/fall of 2011.

Revised NOI for 2012 Sivulliq N submitted to EPA by Shell* (dated December 16, 2010, from Appendix B of Shell's revised CBEP). This revised NOI includes other sites but pages 3/102 through 32/102 apply specifically to Sivulliq N if drillship Discoverer is used (see pages 67/102 through 75/102 if drillship Kulluk is used). This revised NOI included changes to the drilling start date (to July 2012), omits the Drilling Fluids Plan (DFP) and other environmental related reports. Limited and revised facility line drawings of the some of the 14 discharge waste streams was provided but omits waste flow balancing as required by NPDES General Permit AKG280000. The EPA approved the NOI with omissions and this NOI appears to control drilling waste discharges into the Beaufort Sea for the coming summer/fall of 2012.

Sea ice recession because of climate change is also a factor in oil and gas development in the Arctic Ocean. For additional information see Arctic sea ice reduction and sea ice recession.
