The army mentioned it has efficiently “unpacked ” gas from the Navy‘s Pink Hill pipelines, a essential first step to the last word plan to defuel the tanks on the decades-old underground Pink Hill gas farm.
Joint Activity Drive Pink Hill, which is overseeing the defueling, introduced Thursday that it had efficiently eliminated 1, 058, 187 gallons from the pipelines, which join the large Pink Hill tanks to amenities at Joint Base Pearl Harbor-Hickam.
It is the primary time the pipelines have moved gas for the reason that Navy stopped all Pink Hill fueling operations in November 2021, when gas from the ability contaminated the Navy’s water system. The Navy water system gives potable water to about 93, 000 folks on Oahu, together with service members, army households, civilians residing in former army housing areas, faculties and companies.
State officers and the army mentioned they’ve efficiently restored the Navy water system, however the Pink Hill gas tanks–whose present capability was reported as 104 million gallons–sit simply 100 ft above a essential aquifer that Honolulu depends on for nearly all of its ingesting water.
Joint Activity Drive Pink Hill has been transferring the gas to above-ground tanks at JBPHH and to gas storage barges. The Pink Hill facility holds three sorts of gas that every journey down their very own pipeline : F-24 business jet gas ; F-76 marine diesel gas that’s used to energy the Navy’s ships ; and JP-5, the kerosene-based jet gas that contaminated the Navy’s Pink Hill properly.
Till the unpacking started, the gas sat within the pipelines, which span about 2.5 miles and had been constructed to let gravity take gas down from the Pink Hill tanks to the army bases beneath. Throughout the unpacking course of, Joint Activity Drive Pink Hill eliminated 887, 937 gallons of gas from the pipes utilizing gravity and 170, 250 gallons by “low-point switch, ” which concerned pumping the residual gas by the pipes.
The situation of the pipelines has been some extent of concern since a minimum of 2016, when an inner army evaluation discovered the ageing pipelines had been struggling severe corrosion and different issues. Army officers mentioned that gas wanted to be faraway from the pipelines to permit for extra thorough repairs to the pipelines and the remainder of the Pink Hill system to make sure gas could be safely eliminated with out threatening the aquifer or inflicting different disasters.
The Pink Hill facility was constructed underground throughout World Warfare II to make it tougher for enemy forces to strike. The 20 gas tanks, every able to storing as much as 12.5 million gallons of gas, had been put in inside cavities mined right into a volcanic mountain ridge. However its distinctive structure additionally led to distinctive issues safely sustaining and working the practically 80-year-old facility.
Protection Secretary Lloyd Austin ordered the everlasting defueling of the Pink Hill tanks in March after months of efforts by the Navy to battle an emergency order from the state Division of Well being calling on the Navy to empty the tanks.
Getting older infrastructure and upkeep issues have grow to be an more and more seen drawback for the Navy in Hawaii.
In September, DOH levied an $8.7 million superb in opposition to the Navy for 766 counts of discharging undertreated sewage into the ocean between January 2020 and July 2022, in addition to 229 counts of operational and upkeep failures at its JBPHH wastewater remedy plant.
Final month the Navy contested the superb, arguing it can’t legally pay the superb as a result of the state is barred from searching for punitive fines.
The deliberate begin of unpacking operations at Pink Hill was disrupted by a number of water fundamental breaks within the Navy’s Oahu water system Oct. 14 that prompted faculty closures and a boil-water discover. The breaks lowered water strain, leaving Joint Activity Drive Pink Hill with out assets for firefighting within the occasion of an accident in the course of the unpacking operations. The duty power finally started unpacking Oct. 25.
“I need to thank all these concerned within the planning and preparation for the unpacking course of after which all of our teammates for his or her professionalism and secure execution, ” mentioned Joint Activity Drive Pink Hill commander Rear Adm. John Wade in a information launch posted on the Navy’s official web site. “I additionally need to thank our elected representatives, the Division of Well being, the Environmental Safety Company and the U.S. Coast Guard for his or her help, consideration and oversight.”
In a information launch Friday, job power spokesperson James Hoeft mentioned that “throughout this part we are going to conduct all vital repairs, modifications and enhancements to the Pink Hill complicated to cut back threat throughout defueling, ” and that the duty power will “conduct iterative planning in partnership with the Division of Well being and Environmental Safety Company to seek out methods to cut back the defueling timeline safely.”
Army officers say your complete defueling course of is anticipated to be accomplished by the summer season of 2024. But it surely’s not clear that would be the finish of the story. This week the Navy submitted a closure plan to DOH that advocated “closure in place with helpful reuse, ” which might hold the ability in place and discover another use for it.
Throughout a Tuesday information convention at JBPHH, Meredith Berger, assistant secretary of the Navy for vitality, installations and surroundings, advised reporters “we are going to proceed to ensure we’re protecting of the surroundings, of the folks and of the neighborhood, and we’re not–I need to make sure that that is very clear–we usually are not going to pursue any helpful reuse possibility that might comprise potential contaminants, and not one of the choices that we now have laid on the desk could be a gas reuse.”
Protection officers have been hesitant to debate potential particular makes use of of the Pink Hill facility post-defueling however have floated the potential for utilizing it for a hydroelectric plant to offer another vitality supply.
