Milne Point Tract 14 Production Line Release
SITREP #: 1
SPILL #: 15399905901
TIME/DATE OF DISTRIBUTION: February 28, 2015 3:30 p.m.
POTENTIAL RESPONSIBLE PARTY (PRP): Hilcorp Alaska, LLC (HCA)
INCIDENT LOCATION: Milne Point Tract 14 Production Line (approximately 25 miles northwest of Deadhorse and 40 miles northeast of Nuiqsut).
TIME/DATE OF SPILL: 7:50 a.m. on February 28, 2015
HOW/WHEN SPILL WAS DISCOVERED AND REPORTED: A release from a 10” production line was observed at 7:50 a.m. on February 28, 2015. Alaska Department of Environmental Conservation’s (ADEC’s) After Hours Call service was notified at approximately 9:00 a.m. on the same day. ADEC responders were then contacted within 15 minutes.
TYPE/AMOUNT OF PRODUCT SPILLED: An unknown amount of produced fluids including crude oil and produced water were released to the pad and tundra.
CAUSE OF SPILL: The cause of the production line rupture is under investigation, but crude escaped from an estimated 1/4” diameter hole in the 10” production line.
SOURCE CONTROL: Tract 14 wells were shut in. Production flow was stopped, and the 15-foot segment of pipe in which the hole is located was isolated by shutting valves on either side of the hole. Pressure inside the segment is zero. A wooden plug was inserted in the hole and that portion of the production line was wrapped to prevent further release. Containment supplies were placed under the release point to reduce further environmental impact. Remaining product in affected pipe segment is being removed, but is not yet complete.
RESPONSE ACTION: HCA mobilized 13 on site responders, engaged the Alaska Clean Seas response team, and requested mutual aid from the Kuparuk Spill Response Team. A preliminary delineation of the impacted area has been conducted. The site has been isolated from non-response road traffic. Responders have sprayed water onto the affected area to form an ice cap over the contamination keeping it in place; thereby preventing further migration during an upcoming weather event. The ice cap will not interfere with responder’s ability to recover product from the site. An estimated 3,906 gallons (93 bbls) of liquids have been recovered by vacuum truck to date. A Unified Command has been established with HCA, ADEC, Environmental Protection Agency (EPA) and the North Slope Borough (NSB).
RECOURSES AT RISK OR AFFECTED: Preliminary delineation activities have reported that approximately 38,800 square feet of gravel pad and tundra have been heavily to lightly misted by fluids. There has been no reports of impacted wildlife.
FUTURE PLANS AND RECOMMENDATIONS: The primary focus is developing tactics to recover the spilled product from the pad and tundra. In addition, a plan to bypass the affected pipe segment will be established to safely resume normal operations including production line flow to prevent freeze-up of facilities and piping. The affected 15-foot pipe segment will be deinventoried and removed for further inspection and analysis. ADEC will mobilize to the on-site field command post on Monday, March 2, 2015 as weather conditions permit. ADEC will work with HCA to review cleanup plans.
WEATHER: A blizzard is developing along the central Beaufort Sea Coast. Blowing snow in the afternoon is expected with visibility less than one quarter of a mile. Highs in the lower-to-mid 20s. Lows in the minus teens. South winds will increase out of the southwest to 40 mph with gusts to 55 mph.
