Opponents of a plan to build a 150,000-square-foot Wal-Mart store in St. Albans are challenging a state permit granted for the project.
The Vermont Natural Resources Council, the Northwest Citizens for Responsible Growth and nearby farmers say the environmental commission that reviewed the case ignored its own findings.
The VNRC says the commission found that the store would pollute a nearby brook, increase traffic congestion, and pave over prime farm land.
The groups want the commission to revoke the permit.
The district coordinator for the Vermont Natural Resources Board Geoff Green says the challenge was not unexpected, and the commission has not yet reviewed the request.
