hi - yes - we last filled
tanks in Tewksbury last summer. I assume still open. Here are notes from them. I also need another CNG tank. Always something but good problems to have....Have a good season. P
BTW - again as of last summer, the CNG testing facility off Rt 9 is still open - quite an operation.....
Also - there is another CNG filling station near New Bedford - designed for vehicles - i do not know if fitting will
work for our tanks.

We (AVSG) can re-fill the cylinder at our station in Tewksbury (by appointment only) - but it has to be re-certified first - as CNG bottles/cylinders need to be re-certified every five (5) years. You can self-inspect the cylinder to confirm the date of its last inspection. Here's the information you'll need:
Here's some guidance regarding the refilling of CNG cylinders:
First, all cylinders must be within specification,
i.e. having been re-certified within five (5) years. The date of inspection/re-certification is typically stamped (not a label) just below the neck (narrowest section) of the cylinder. It's usually in the form of "10xyz18" for October of 2018 or something similar.
If the cylinders are within specification, please reach out to Iris Hill via email (ih@avsglp.com) or at (978) 562-3500 and she'll work with you to schedule an appointment with one of our technicians.
She can arrange to have a technician meet you in Tewksbury (MA), the town adjacent to the city of Lowell, with a day or two of advance notice (and this is our only marine CNG refilling location). We typically meet customers (it is notself-service) early in the morning or late in the afternoon as the techs are traveling throughout the middle part of the day.
The CNG facility is located in Tewksbury at Exit 92 off of Route 495. The address is 20 Main Street (a/k/a Route 38) and intersects with Clark Road. There is a Market Basket shopping mall directly across the street from our station. It's ten minute process per cylinder fill. We're charging $65 (cash only - no other payment option at this time) per cylinder.
If the cylinder(s) is/are out of certification, please contact Northeast Pressure Vessel Testing (NEPVT) at (508) 389-1212.
You'll need to set up a drop-off day for your cylinders to be tested, recertified, painted, and then stamped. NEPVT's address is 97 Turnpike Road in Westborough, MA. Once dropped off, NEPVT will need a day or two (unless NEPVT can accommodate a tighter time-frame) to complete the testing/recertification/painting process. Fee is typically $35 per cylinder for this comprehensive service. Once recertified, the cylinders are good for another five (5) years. This is a US DOT regulation.
Hope this helps and happy CNG sailing!
