Juniper Ridge Landfill in Old Town is expected to fill in less than seven years at the current rate of disposal, which is prompting Casella Waste Systems - the company hired to operate it - to prepare an expansion plan. "Literally since 2005, we've been at this," Don Meagher, Casella's manager of planning and development, said on Thursday at the company's fourth and final "Milestone Meeting" in advance of filing their expansion plans in 2015.
