An Act relative to the closure of the Saugus ash landfill

This bill mandates the closure of the Saugus ash landfill in Saugus, Massachusetts, by requiring the facility to stop all operations and install a permanent cap. The closure must occur by December 31, 2026, or sooner if specific conditions are met, such as filling two drainage valleys to a required slope or disposing of 450,000 tons of ash. These provisions directly affect the operator of the landfill and the surrounding community by setting a definitive timeline for the site's retirement. The legislation ensures that the landfill is sealed once these operational limits are reached, regardless of other existing laws.
