taminants, a detailed certificate must be filled out before disposal is allowed, the chairman reported.
Bill Worrell, the biochemist who will be working with Kuncewicz on the tannery, reported that the 15 pounds of chromium produced weekly as a byproduct will not leach through the soil if disposed of in the landfill. Trivalent chromium, the compound used in tanning, is not harmful. according to Worrell. “EPA took it off their 'hit list’,” he said.
Worrell noted that federal and state agencies have powers to regulate the tanning operation to ensure there is no pollution. “Both the Environmental Protection Agency and the State Water Control Board will investigate what we’re doing,” he said.
“You have to do your homework to make sure the Thornton River,is protected." Luke emphasized, noting that water will be returned to the river after its use in tanning. Worrell assured the supervisors that an engineer from the SWCB will have to approve that phase of the tanning operation. Luke indicated that the board will have questions at the March public hearing both for the SWCB engineer and for a representative from the Health department.
