After months of investigation by the the Environmental Protection Agency and a private investigator hired by Oak Harbor School District into the illegal dumping of the pesticide Dursban on school district property, two district employees no longer have their jobs.

Gary Hansen, the maintenance and grounds director, resigned after the district received the final report from the private investigator regarding the dumping of the toxic substance near a school bus garage on the corner of Midway Blvd. and Whidbey Ave., said Rick Schulte, school district superintendent, on Tuesday.

Steve Newman, a groundsperson, was fired after the investigation concluded that he had actually dumped the Dursban at the site.

“The investigator said (Hansen) knew or he should have known” that the Dursban had been dumped, Schulte said. Newman was fired for not only doing the dumping, as the investigation alleges, but for withholding that information from the district at the beginning of the investigation.

The illegal dumping came to light last spring when former district employee Michael Zuercher made a report to the EPA. Everything that Zuercher reported that was verifiable was, in fact, verified, Schulte said.

There could still be criminal charges pressed against “individuals,” Schulte said, but he doesn’t expect any charges to be filed against the district. After the district cleaned up the site in April, the EPA sent Oak Harbor School District a letter stating that it was satisfied with the action taken by the district, Schulte said.

Meanwhile, a temporary replacement, Jack Thompson, has been hired to fill Hansen’s role as well as to complete an assessment of the grounds and maintenance department, Schulte said.

“I feel good about it being wrapped up,” Schulte said.
