Dear Ms. Harradence:
On October 16 – October 20, 2017, and May 15-17, 2018, a representative from the Pipeline and
Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United
States Code, conducted an on-site pipeline safety inspection of Algonquin Gas Transmission,
LLC’s (Algonquin’s) procedures in Waltham, Massachusetts. As a result of the inspection,
Algonquin was issued a Notice of Amendment on August 12, 2019, which proposed amendment
of your procedures.
Algonquin submitted its amended procedures on September 10, 2019. My staff reviewed the
amended procedures, and it appears that the inadequacies outlined in this Notice of Amendment
have been corrected.
This letter is to inform you no further action is necessary and this case is now closed. Thank you
for your cooperation.
Sincerely,
Robert Burrough
Director, Eastern Region

NOTICE OF AMENDMENT
OVERNIGHT EXPRESS DELIVERY
August 12, 2019
Michele Harradence
VP Gas Transmission & Midstream Operations
Algonquin Gas Transmission, LLC
5400 Westheimer Court
Houston, TX 77056
CPF 1-2019-1015M
Dear Ms. Harradence:
From October 16 - October 20, 2017 and May 15 - 17, 2018, a representative of the Pipeline and
Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601 of 49 United
States Code (U.S.C.), inspected Algonquin Gas Transmission, LLC (Algonquin)’s procedures for
the Mystic River HDD Project in Waltham, Massachusetts.
On the basis of the inspection, PHMSA has identified the apparent inadequacy found within
Algonquin’s plans or procedures, as described below:
1. § 192.303 Compliance with specifications or standards.
Each transmission line or main must be constructed in accordance with
comprehensive written specifications or standards that are consistent with this part.
Algonquin’s written specifications and standards for constructing each transmission line were
inadequate. Specifically, Algonquin’s construction standards for coating inspection failed to
adequately address the requirements of § 192.307 and § 192.461(e) regarding pipe that was
horizontally directionally drilled (HDD).



CPF 1-2019-1015M
During the inspection, a PHMSA inspector requested procedures for assessing and remediating
coating that may have been damaged as a result of installation via HDD. Algonquin provided
COATING DESIGN FOR HDD INSTALLATIONS (Guideline Number: DG-PC1.1 and
Revision Date: 11/04/2014) (Design Guideline).
Section 192.307 stated “Each length of pipe and each other component must be visually inspected
at the site of installation to ensure that it has not sustained any visually determinable damage that
could impair its serviceability.” The Design Guideline did not address inspecting piping in the
exit pit that was installed via HDD in order to determine if any damage occurred that could impair
its serviceability, and also subsequent remediation requirements that may be necessary in the event
damage was discovered.
Section 192.461(e) stated “If coated pipe is installed by boring, driving, or other similar method,
precautions must be taken to minimize damage to the coating during installation.” The Design
Guideline did not address inspecting the coating condition of piping in the exit pit that was installed
via HDD, and subsequent remediation requirements for damaged coating.
Therefore, Algonquin’s construction standards failed to address inspecting and remediating, if
necessary, the coating of piping in the exit pit that was installed via HDD to comply with
§ 192.461(e). Also, the procedures did not address inspection of said pipe to determine if any
damage occurred during the HDD installation that could impair its serviceability to meet
§ 192.307, and subsequent remediation, if necessary.
