A newly revised list ranking the potential sites for a new landfill, put the top four on Oahu’s North Shore.
The top two parcels on the revised ranking are in Kahuku.
The sites are federally owned and adjacent to each other, and are part of an area used for army training.
Third and fourth on the list are two sites in Pupukea.
The Kailua rock quarry which topped the list last week, is now ranked fifth.
Two companies that apologized for the miscalculation at the Friday meeting of the mayor’s landfill advisory panel, faced cameras Wednesday to explain what happened.
"On Sunday, April 2nd, a data error was discovered that occurred during Friday's meeting. The error took place during a 15-20 minute break, when adjustments to the data was being made," said Brian Takeda, project manager for R.M. Towill.
The head of the SMS Research, the company that made the mistake, took full responsibility for the error.
"That's my career. This is what I do for a living, and I usually don't make mistakes like that. It is very difficult to say how any score was changed, but they were changed because of the numbers that I inadvertently entered," said James Dannemiller, of SMS Research.
The numbers, he explained, included criteria around distances to things like homes, schools and hospitals, as well as what he called community dis-ammeneties, and factors like rainfall and surface water.
On hand for the news conference were a Kailua lawmaker, and the president of the Ameron rock quarry, which has the contract to supply the concrete for the city's rail project.
"I am grateful it is down to the fifth level, but if one of the sites is knocked out, one because it’s a military property, or the other for other reasons, then that would put Ameron back up at the top," said Rep. Cynthia Thielen.
"I wouldn't say we are relieved, as Cynthia said, we are still on the list and there is every intent to fight this vigorously,” said Ameron’s Wade Wakayama.
Mayor Peter Carlisle said at least the error was discovered and corrected quickly.
“I am disappointed the consultant miscalculated data regarding such an important issue, especially after members of the Advisory Committee on Landfill Site Selection volunteered their time for more than a year to carefully establish evaluation criteria and recommend a site to supplement or replace the Waimanalo Gulch Sanitary Landfill,” said Carlisle.
The desktop ranking of the sites is just the beginning of a process to open a new landfill, that according to the city, could take seven years.
