Cleanup of the former Exide property is headed for another year of heavy spending. Three contract increases worth about $3.77 million combined are on the consent agenda when the Frisco Community Development Corporation board meets Thursday, Oct. 15.
The board, a nonprofit that the staff memos describe as exempt from the state's competitive-bidding rules for cities, would pay for all three from its own fund. Staff recommends approval of each.
The three requests
- Remediation Services Inc., the contractor doing the field work, would get $2,885,703 more. With $4,762,124 still left on its current purchase order, that sets the fiscal 2027 remediation budget at about $7.65 million.
- WSP USA, the project engineer, would get $699,000. Its purchase order has no money left, according to the memo, and the new amount covers field oversight, sampling and lab costs for the year.
- Eco-Southwest Environmental, the CDC's lead consultant, would get $187,284. The board approved up to $730,000 for the firm last November, so the agreement would total $917,284.
Where the money goes
A Sept. 9 budget letter from Remediation Services breaks the $7.65 million into the cleanup tasks approved by the Texas Commission on Environmental Quality. The largest pieces are:
- Removal of the remaining contaminated soil on site: about $3.27 million
- On-site cleanup of Stewart Creek: about $1.53 million
- Completing the funnel and permeable reactive barrier, an underground wall meant to treat groundwater: about $1.2 million
- Bringing in roughly 30,000 cubic yards of fill soil from nearby projects: $540,000
- A retaining wall: $467,134
- Capping the South Disposal Area: $396,000
- Capping the Parkwood parcel: $251,256
The contractor says its soil estimate is a worst case drawn from overruns in other areas of the site, and it includes treating soil and slag that test as hazardous waste. It also budgets 10% more for synthetic liner on two caps.
Work on a leachate system for the North CAMU, a lined disposal cell, and on a solar pond is now expected in fiscal 2028.
By the contractor's own figures, about $21.3 million had been billed against its $26 million purchase order through Sept. 30, part of that an estimate for the final three months. Its cost sheet puts the total for its remediation work, from the start through fiscal 2027, at about $28.9 million.
