Elevated Gas Pressure Permitting Process
The Modifications of the Massachusetts Fuel Gas Code 248 CMR 5.00 allows for requests for elevated pressure (greater than 14"w.c. or 1/2 psig) when “ the gas utilization equipment specifically requires higher pressure or when low pressure installation design requires pipe size in excess of 4" IPS and the piping load is detrimental to the building structure.”
The following requirements are necessary in order for Columbia Gas of Massachusetts and the Commonwealth of Massachusetts to consider an application for elevated natural gas pressure for a facility. Before completing the application contact your Columbia Gas Commercial Sales Representative to determine if elevated pressure is available in your area. You may also contact our New Business Team at 1-888-639-4270. A representative will answer any questions you may have.
Customers must first submit an Application for Elevated Gas Pressure to Columbia Gas Company for approval. An application can be found on the state’s website at www.mass.gov/dpl/boards/pl/forms.htm. The application should be accompanied by a detailed equipment listing that includes the BTU input rating and required pressure for each piece of equipment to be serviced by the associated natural gas meter. Upon completion, this application should be mailed to your Columbia Gas Commercial Sales Rep.
If elevated pressure is available, Columbia Gas will review the application and upon approval return it to the customer. It is the customer’s responsibility to forward the application to the Board of State Examiners of Plumbers and Gasfitters, along with the required payment and a copy of the piping plans. All submitted plans, diagrams, and schematics must be stamped and signed by a Massachusetts Registered Professional Engineer. Typically, the turn around time at the state is 3-6 weeks.
The piping diagram must show the gas meter, all gas fired equipment (existing and new), their respective maximum input firing rate(s), pipe diameters, and pipe lengths.
If the equipment specifically requires elevated pressure, a copy of the equipment specifications indicating the required pressure shall be included.
All elevated gas piping, fittings, and controls subject to the elevated pressure shall be welded.
Modifications to existing threaded systems will be evaluated on an individual basis.
Once you are granted approval, send a copy of the approval to Columbia Gas of Massachusetts. Be sure to keep a copy at the facility for future reference.
If at any time gas piping associated with the elevated pressure gas meter is altered, a new application must be made. Please contact your Columbia Gas, Commercial Sales Representative with any questions or concerns.
