Artel and Smiling Hill Farm have appealed an agreement that would allow Pike Industries to mine its rock quarry in Westbrook’s Five Star Industrial Park.

The agreement was approved last month by Maine Business Court Justice Thomas Humphrey.

The agreement, which restricts how Pike may operate its quarry, satisfied initial objections to the quarry by Idexx Laboratories and the city.

But lawyers for Artel and Smiling Hill Farm say the agreement usurps zoning functions normally reserved for municipal planning boards and town councils.

No court dates have been scheduled yet.
