Thousands of gallons of raw sewage spilled out of the McCully Shopping Center in August and it wasn't until KHON2 showed up on scene that authorities and the public were made aware of what was going on.
But it turns out, that wasn't the first time sewage spilled out of the shopping center.
KHON2 searched city and state records to find out there were similar sewage spills as early as February of this year, also in 2009 and 2007.
But so far, the shopping center has only been fined from its 2007 case.
"If it goes into the water, go up to $25,000 per day, per violation. If it stays on the ground, it could be up to $10,000," said Michael Tsuji, Clean Water Branch supervisor.
Even though the reports show all of these spills reached the Ala Wai Canal, McCully Shopping Center was fined a total of $2,280.
The most recent spill is still under investigation.
The Department of Health requested a copy of KHON2's video to use as evidence of whether or not the sewage reached the canal.
"Have any fines been issued at this point?" KHON2 asked.
"At this time, no," Tsuji said.
"Why is it taking so long?" KHON2 asked.
"The investigation can take months to a couple of years, actually," Tsuji said.
An example of a case that has taken years to investigate is the Waimanalo Gulch Landfill spill back in January of 2011, where medical waste like hypodermic needles, syringes, and vials full of blood washed onto west Oahu shores.
No fines have been issued yet in that case either.
"We are working actively on several cases at this time. Unfortunately, it does take awhile to build up a case, but when it does happen, you'll be notified," Tsuji said.
He says environmental spill cleanups can cost the state thousands of dollars -- money that comes out of the DOH's operating fund.
Any fines collected go into a special environmental response fund.
"We can't tap into that, not for our day-to-day operations," Tsuji said.
McCully Shopping Center's property management company says it has now implemented a plumbing maintenance program, where the lines will be cleared on a monthly basis.
They are also doing camera work to monitor the build-up to make sure this doesn't happen again.
