The Details

What you need

The approval is to construct a well. All the requirements of 310 CMR 22.21 and the Division of Water Supply's Guidelines and Policies for Public Water Systems (available in the State House Bookstore) should have been satisfactorily addressed. This is the last approval in the New Source Approval process.

Approval to construct a source is an indication that all the requirements of the New Source Approval process have been addressed satisfactorily. 

Any individual, company, municipality or district intending to develop a public source of water supply serving 15 service connections or 25 individuals at least 60 days per year must apply for this approval.

The following requirements should be considered when applying for this approval:

  • DWS Water Management Act approval application has been filed.
  • Prior to final approval, proponent must own or control Zone I.

Before issuing an approval to construct, the Division of Water Supply will evaluate whether all of the components of the Source Approval process have been satisfactorily completed. Prior to the source going on-line (pumping water into the distribution system), the Wellhead Protection Zoning and Nonzoning controls and the Groundwater Monitoring Well Program must be implemented and functioning.

Note: Approvals of this type may require MEPA review. Please carefully examine 301 CMR 11.00, the MEPA Regulations, to determine if your project exceeds the MEPA review thresholds, or for more information contact the MEPA Unit of the Executive Office of Environmental Affairs (100 Cambridge Street, Boston, MA 02202; 617-727-5830). MassDEP cannot begin technical review of the permit application until the MEPA process has been completed, unless otherwise agreed to in writing. Copies of MEPA filings (with reference to any applicable Transmittal numbers) should be sent to the appropriate program offices in Boston and the MEPA Coordinator in the appropriate Regional Office.
