On May 15, 2023, the Region issued an administrative order (AO) to the Randolph-Holbrook Joint Water Board (serving the Towns of Randolph and Holbrook, Massachusetts) requiring that the Board to take actions to address unpermitted discharges from its drinking water plant's (Plant's) sedimentation tank into Great Pond. The AO requires the Board to evaluate environmental harm caused by the unpermitted discharges. The Board must submit and implement a plan for remediation of environmental harm and removal of accumulated solids. The Board must also complete construction and commence operation of a new drinking water plant and cease all discharges from the current Plant. It is estimated the new drinking water plant will cost $122 million. For the interim period before the Plant ceases operation, the AO requires the Board to submit and abide by an Operations Plan to minimize impacts of the Plant's discharges, and includes the development of a Best Management Practices Plan. Residents of these Towns are impacted by Environmental Justice issues. The Region worked in close coordination with the Massachusetts Department of Environmental Protection in this matter.
