Fayette contamination update 8.8

Posted in 2007 August

GREEN SPACE

Fayette village council members had a lot of questions for the Ohio EPA last Wednesday, mostly focusing on the future use of the school property.

The settlement reached in March between DH Holdings—the company responsible for cleaning up the contamination from the former Fayette Tubular Products site—and Gorham Fayette Board of Education not only calls for the demolition of all existing school buildings on the contaminated property, but it also prevents future construction at the site.

Edward Onyia of the Ohio EPA said his agency was initially working on a plan that would allow use of the property in the future when the cleanup is completed. That changed when he learned details of the settlement with DH Holdings calling for green space.

Councilor Ruth Marlatt asked about long-term plans, for example, 50 years in the future when no threat exists.

“The agreement says no buildings, ever,” Onyia answered. “That’s what the school board and DH agreed on.”

Superintendent of Schools David Hankins said later that green space wasn’t the school board’s desire, but it was a condition listed in the $3.9 million settlement. DH Holdings insisted on demolition, explained attorney Henry Heuerman of Eastman and Smith—the law firm firm representing the district—to prevent further claims arising from use of the buildings.

DEMOLITION

The Ohio EPA’s original plan for the school property didn’t call for demolition of the existing structures, said the agency’s Edward Onyia.

As cleanup proceeded, the situation would be analyzed and future use would be determined.

That all changed when the Gorham-Fayette school board accepted DH Holdings’ cash settlement from a lawsuit regarding the contaminated property stemming from operations at the former Fayette Tubular Products site.

However, the Ohio Schools Facilities Commission—a state agency funding about 80 percent of the new school construction—also favored demolition and even budgeted costs for the work.

The master plan from September 2003 calls for expenditures of $391,160 for demolition of the old school and newer gymnasium, plus $35,712 for removal and disposal of hazardous materials.

The Ohio EPA’s George Stuckey told council members last week that asbestos removal would be the primary concern, however, school superintendent David Hankins said later that the majority of asbestos was removed in a project several years ago.

Contamination in ground water would probably not be affected by demolition, Stuckey said, but the demolition process will be monitored, Onyia added.

School superintendent David Hankins said that $86,615 is budgeted for demolition of the Franklin building south of Fayette, plus $23,013 for hazardous materials.

However, there’s a chance the Franklin building won’t be demolished because it has resale value, he said, but that’s a decision for the school board to make.

TRENCH TO GROW

What to do about the remaining contamination on the Fayette school property?

More of the same, says Edward Onyia, project manager for the Ohio EPA.

“The best approach is to continue what we’re doing now,” Onyia told village council members at an update meeting Aug. 1.

That means using “active chemical treatment” of a substance injected into the soil, and filtering ground water collected in an underground trench. In addition, he said, the trench will be enlarged.

The trench system appears to be working, said the Ohio EPA’s George Stuckey, with one exception: the original design apparently didn’t extend far enough to the west and ground water flowed around the end, then continued the southeasterly flow onto school property.

According to Dina Pierce, media relations specialist for the Ohio EPA’s Northwest District, the trench will extend into the public right-of-way (Gamber Street), but the engineering design is not yet available.

First, the agency will release a preferred plan of action and seek public opinion on the plan, perhaps in early December, then a remedial design will show how the preferred plan will be carried out.

One plan will address soil contamination and the other will be aimed at ground water contamination. The Ohio EPA will choose a plan from about a dozen submitted by DH Holdings—the company responsible for cleaning up the contamination. The plan will be chosen based on three criteria: public health, cost effectiveness and acceptance by the community.

Update

Council member Mike Maginn asked if the contamination was still moving and Stuckey answered that it will continue to flow with the ground water.

Stuckey brought graphs tracking a few of the six chemicals being monitored and said the overall pattern shows a decrease, despite fluctuations caused by changes in precipitation.

Maginn asked about the possibility of contamination moving down the hill in front of the school and onto the ball field area.

“We don’t have any monitoring wells there,” Stuckey said.

“We’ve defined the edge of the plume,” Onyia added about the constantly moving  area of contamination.

The monitoring well located in front of the school is showing the highest concentration ever of one substance and one of the largest detections of another. However, all detections are less than those found in other wells to the north.

Pierce explained later that if contamination were to flow beyond the school property, it would not pose a risk to the public.

“One risk from the plume is in the water. No one is drinking the water, so that risk is removed,” she said. “The other risk is for indoor vapor intrusion. Once the vapor is exposed to open air (outdoor air), it disperses quickly. The concern is when vapors are confined indoors.”

Pierce said the plume of contamination is moving quite slowly.

“Even if no remediation is done, there shouldn't be significant movement in a year’s time,” she said. “And in coming years, remediation requirements in the preferred plan will attack the contamination before it moves significantly.”

On school property, for example, contamination will be chemically treated to “render it harmless.”

The trench will be extended to cut off the flow of contamination.

“This is important,” she said, “because there are still homes nearby and we don't want to risk the plume moving that far.”
