Tetra Tech Inc. project manager Daphne Digrindakis said an earlier estimate of $130,000 in cleanup costs was preliminary and didn't include all of the data gathered during site explorations this spring.
The company's most recent estimate is $178,000 for soils mitigation, though that figure doesn't include the costs of lead-paint and asbestos abatements in the existing structures. It also doesn't contemplate cleaning up soils beneath the buildings at the east end of the Malfunction Junction intersection -- workers haven't been able to analyze contaminant levels there, she said.
"All parties concerned should plan for around $200,000," Digrindakis said. "We're very confident that the bulk of it can be cleaned up for (that amount.)"
She noted several opportunities for funding to clean up the 2.4-acre plot, which has been an industrial site for more than a century.
The U.S. Environmental Protection Agency's Brownfields program offers competitive grants for cleanups to government agencies and nonprofit groups, providing a maximum of $200,000. Also, a coalition of economic development agencies in Montana have pooled $1.6 million in funding for a revolving-loan program for remediation work, with some of that money available as grants for cities, counties and nonprofit agencies.
Tetra Tech's work, the first comprehensive study of the site's contamination levels, was funded through the Brownfields program, coordinated by Lewis and Clark County in conjunction with the federal government.
