Meter Stations

As part of the Project, Tennessee proposes to construct 13 new meter stations and modify 12 existing meter stations located in New York, Massachusetts, New Hampshire, and Connecticut.12

The construction and modification of custody transfer meters is to meet the specific needs of Project Shippers contracting for firm transportation service on the Project. The work involved at new meter stations will include the installation of tap, metering, regulation, heating, flow control, and overpressure protection, as necessary unless specified otherwise. The work involved at existing meter stations will include the modification to the station tap, inlet piping, headers, meter runs, and outlet piping as necessary, unless specified otherwise. Footprints of new meter stations are assumed to impact approximately 0.92 acres of land based on Tennessee’s experience with constructing and operating existing station requirements; these impacts will be refined as civil and field surveys are completed and final designs are developed.

Meter stations are built for the purposes of measuring continuous natural gas flow entering and exiting a pipeline system. Meter stations also possess regulating components which regulate the pressure and delivery volumes of natural gas into and out of the pipeline system.

Table 1.1-4 provides further information on the proposed modifications to existing and new stations. Meter station locations are included on 7.5-minute USGS topographic quad excerpt maps and full size aerial alignment sheets are included in Volume II, Appendix E and Appendix F, respectively.

New York

New meter stations in New York will include:

x IGT-Constitution Bi-Directional Meter – Schoharie County, New York;

x NED Check – Schoharie County, New York; and

x Fitchburg Lateral Check – Worcester County, Massachusetts;

x Longmeadow – Hampden County, Massachusetts;

12 _{Additionally, although the following existing Tennessee meter stations will have an increase in contracted quantities as a result} of the Project, no modifications to the meter station facilities or land disturbance will be required: Clinton, Cranston, Pawtucket, Dracut, Acton, Tewksbury, Haverhill, M aple St./Danvers, Camp Curtis, Revere, Lynn, Salem, Gloucester, Wenham, Lynnfield, West Peabody, Wilmington, Agawam, and E. Farmington.

x Everett – Middlesex County, Massachusetts;

x North Adams Custody – Berkshire County, Massachusetts (modifications include installation of a new tie-in assembly that includes fitting, tap valve, riser, and check valve; and new interconnecting station piping and metering);

x Lawrence – Essex County, Massachusetts (modifications include installation of a new tie-in assembly that includes fitting, valve, and riser, modifications to the existing interconnecting piping station and metering, and the addition of cathodic protection);

x Southbridge – Worcester County, Massachusetts (modifications include replacing the tap, inlet piping, outlet piping and modifications to the existing meter tube inlet header);

x Spencer – Worcester County, Massachusetts (modifications include replacing the inlet and outlet station piping with larger diameter piping to accommodate the increased flow rates);

x Leominster – Worcester County, Massachusetts;

x Lunenburg – Worcester County, Massachusetts (modifications include either adding an additional tap and tap valve or increasing the size of the existing tap and tap valve, increasing the size of one meter run, increasing the size of the inlet system piping, and adding gas quality instrumentation):

x Lexington – Middlesex County, Massachusetts;

x Burlington – Middlesex County, Massachusetts (modifications include either adding an additional tap and tap valve or increasing the size of the existing tap and tap valve);

x Arlington – Middlesex County, Massachusetts;

x Reading – Middlesex County, Massachusetts (modifications include increasing outlet pipe diameter); and

x Essex – Essex County, Massachusetts.

New Hampshire

The new meter station in New Hampshire will be:

x West Nashua – Hillsborough County, New Hampshire.

Connecticut

The modified meter station in Connecticut will be:

x Easton – Fairfield County, Connecticut (modifications include replacing an existing meter bypass with an additional meter run with an accompanying actuated valve).
