This section provides a general description of the permits required for bioengineering bank stabilization work in Massachusetts. Links to examples of some of the permits issued for the bioengineering sites in the Turners Falls Power Pool, including the recently constructed large woody debris (LWD) sites, are also included in this section. The permitting process for the bioengineering sites includes review and approval of the following agencies:

Local Conservation Commission
Since March 2001, all Orders of Conditions issued by local towns (Gill, Northfield and Montague) for bioengineering bank stabilization work in this reach of the Connecticut River have included similar Special Conditions to protect rare dragonflies.

The Notice of Intent filing and the Order of Conditions for the large woody debris (LWD) sites are included in the Publications section ((link to reports)

Massachusetts Historical Commission

Army Corps of Engineers (ACOE)

Massachusetts Department of Environmental Protection (MA DEP)
A 401 Water Quality Certification permit must be filed with the MA DEP.Previous phases of work had not triggered an individual certification. However, with the large woody debris (LWD) design for Phase IV sites, the DEP issued a 401 Water Quality Certification ( link to permit). To date, the MA DEP has determined that since all proposed work is to be done on the "bank", a Chapter 91 Waterways License is not required.( link to 401 certificate)

Massachusetts Environmental Policy Act (MEPA)
The MEPA unit has been involved with the efforts to repair eroding riverbank in the Turners Falls Power Pool since an Environmental Notification Form (ENF) was submitted on behalf of Northeast Utilities in 1990 for a proposed project which would have installed rip-rap along 4,500 linear feet of riverbank in Gill. The Certificate issued by the Secretary of the Executive Office of Environmental Affairs (EOEA) required the preparation of a Draft Environmental Impact Statement (DEIR). The Draft EIR evaluated the 76 sites identified in the 1991 Connecticut River Riverbank Management Master Plan prepared for the utility by Northrop, Devine & Tarbell, Inc. The Final EIR, approved in 1996, described a project to repair 4,800 linear feet of riverbank over the next five years (Phase I). The design to stabilize the banks had evolved from armoring the banks with rip-rap to a hybrid approach which used a stone toe and bioengineering techniques to revegetate and stabilize the remaining bank.
