Mr. Peluso,
Please find attached a request for a gas variance for the biogas conditioning system installed at GLSD. A hard copy of
V
the application, drawings and $86 check for the application fee are being overnighted.

Hello Dan,
You will have to apply for a gas variance for the additional unlisted equipment.We will follow the same procedures as we
F
did with the prior unlisted equipment.

Hi Joe,
The siloxane and H2S scrubbers were not included as an unlisted appliance variance. When we submitted the initial
group of variances we thought these components upstream of the meter would be exempt from the plumbing board
jurisdiction. However when we received the board's decision that it was not exempt, we believed siloxane and H2S
scrubbers were approved as part of the post install variance GV136. We have submitted unlisted appliance variances for
the gas train/blending system for an engine generator(GAV130) and waste gas burner(GAV150)only.
If we are in error and need to submit a unlisted appliance variance for the H2S and Siloxane scrubber systems please
advise, and we will submit immediately.

You are correct, that is part of your design and would fall under the variance for the unlisted equipment, which has already
been granted.
Just a point of information, the email that I sent to the inspector(Steve Galinsky)and yourself last week keeps bouncing
back regarding Steve receiving it. I will try to reach him by phone today but if you have a chance I suggest you try to
reach him also to make sure we are all on the same page so we can finalize this installation. Please keep me informed if
there are additional questions and thanks for your assistance.

Hi Joe,
The siloxane and 1-12S scrubbers are not designed to meet the pressure testing required for piping. They are designed to
withstand a pressure test 1.5 times their maximum allowable working pressure and are protected by a pressure relief
valve set at their maximum allowable working pressure.
If the siloxane and H2S scrubbers were approved as an un-listed appliance would the siloxane and H2S scrubbers still be
required to be tested per the requirements below? If they would not be subject to the pipe requirements CDM Smith \
would like to submit an application for a un-listed appliance for each scrubber system.

Good afternoon Mr. Flaherty, o
Regarding your questions below, I have copied the pertinent sections of the code which indicate the testing requirements. �w
5.6.2.2.1 Welding of Steel and Wrought Iron Pipe. RR
a Welding shall not be construed as the practice of gas-fitting, however, a licensed plumber or gas
fitter may not utilize welded pipes and fittings unless they conform to the specifications cited in
subsections 5.6.2.2 and A.5.5.1 (1).
(b) Gas piping systems with pressures under or equal to 70 P.S.I.G shall only be permitted to utilize
welded pipes and fittings when:
1. The inspector has performed a visual inspection as to the quality of the weld; and
2. The test pressure used during an Inspection complies with the following:
a. a� stems with a maximum operating "
Y p g pressure of ten P.S.I.G. or less, shall be tested to a
minimum of three P.S.I.G. or ten times the operating pressure, whichever is greater.
b. b. Systems with an operating pressure greater than ten P.S.I.G. and less than or equal to 70
P.S.I.G. shall be tested at 100 P.S.I.G.
c. The test duration shall be one hour for every 100 feet of pipe, or fraction thereof. The minimum
test duration shall be one hour and the maximum test duration shall be 24 hours, irrespective of system �"
design. 10
`
(c) Gas piping systems with pressures over 70 P.S.I.G. may only utilize welded pipes and fittings when:

B 1. All welds are of full penetration; and
2. The welds are subjected to the following tests:
a. a. All welds are subjected to a 100% X-ray or 100% Ultrasonic Examination (UT) test unless
they are socket welded;
b. b. All socket welded type joints must be subjected to a magnetic particle test or other non-
destructive test;
C. c. The gas piping system shall be pressure tested to a minimum of 1.25 times the gas piping
systems working pressure. However, the test duration must be a minimum of one hour and the test
must be witnessed by the Inspector; and,
d. d. Any testing company or field agent that provides a (UT) field examination must meet the
requirements of 248 CMR 3.04(6). A copy of the testing certification shall be submitted to the Inspector.
3. Repairs that are made to welded joints that fail the X-Ray or (UT) test shall be re-tested and
re-certified. For future reference; the failed welded joint that is re-tested shall be identified by
stenciling '/z inch high white lettering at the weld location the date of the re-test.
4. The Inspector shall require an affidavit signed by the individual who performed the X-ray or �
(UT) examination for the testing agency. The affidavit shall state that all welds meet the
requirements of the applicable specifications and tests.
5.08: Modifications to Chapter8, Inspections, Testing and Purging:
2. Gas piping systems that extend from the outlet of the service meter assembly to the closed
shutoff valve at each appliance shall satisfy the following:
a. withstand a pressure test of not less than six inches of mercury or three PSIG for a period of
not less than ten minutes without showing any drop in pressure;
b. the pressure shall be measured with a mercury manometer, slope gauge or an equivalent
device so calibrated as to read in increments of not less more than 0.1 PSIG; and „
c. Where new branches are installed to an existing gas piping system, the newly installed
branch(es) shall be required to be tested in compliance with this section so long as the newly installed
branch(es) can be isolated from existing branch(es). Connections between the new piping and the
existing piping shall be tested with a noncorrosive leak-detecting fluid or leak detecting methods
as authorized by this code.
3. Gas piping i in systems in excess of one million BTU input shall be tested at a pressure not less
than ten times the proposed maximum working pressure of the gas system and:
a. the test duration shall be not less than one hour per 100 linear feet of piping or a fraction
thereof: and:
b. The maximum test duration shall not exceed a 24 hour time period irrespective of the piping
system design, and:
c. The maximum test pressure shall not exceed 100 PSIG.

Mr. Peluso,
Following up on our previous conversations regarding testing of the H2S and siloxane scrubber pressure vessels, I
request an email (similar to the one below)stating that the methodology provided below is acceptable to the plumbing
board for pressure testing the vessels.
I.The pressure vessels are tested at 1.5 times maximum allowable working pressure in the factory. R
2.The pressure vessels are field tested after installation at all welds and connections with a non-corrosive leak
detection fluid.
Thanks,
Dan Flaherty

Dear Mr. Galinsky,
On 03/07/18 the Board addressed a Post Installation Gas Variance request for the above referenced location (GV 136).
The request was to allow the installation of stainless steel pipe for above ground location of the Bio gas system.The
variance was granted and based on the engineers design. The Board has information confirming that the use of 304
schedule 10 stainless steel pipe is installed per the engineers design and is acceptable. ;
