Dear Mr. Hallam:
On June 4-6, 2024, 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 Boardwalk Pipeline Partners LP’s (Boardwalk) procedures in its
Leesville and Wilfred underground gas storage facilities in Lawrence County and Sullivan County,
Indiana. As a result of the inspection, Boardwalk was issued a Notice of Amendment on August
14, 2025, which proposed amendment of your procedures.
Boardwalk submitted its amended procedures on September 12, 2025. 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
VIA ELECTRONIC MAIL TO: Scott.Hallam@bwpipelines.com
August 14, 2025
Mr. Scott Hallam
President & Chief Executive Officer
Boardwalk Pipeline Partners, LP
9 Greenway Plaza, Suite 2800
Houston, Texas 77046
CPF 1-2025-017-NOA
Dear Mr. Hallam:
From June 4 through June 6, 2024, a representative of the Pipeline and Hazardous Materials Safety
Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.) inspected
Boardwalk Pipeline Partners LP’s (Boardwalk) procedures for its Leesville and Wilfred depleted
aquifer underground natural gas storage facilities in Lawrence County and Sullivan County,
Indiana.
As a result of the inspection, PHMSA has identified apparent inadequacies found within
Boardwalk’s plans or procedures. The items inspected, alleged inadequacies, and proposed
revisions are described below:
1. § 192.12 Underground natural gas storage facilities.
(a) ...
(c) Procedural manuals. Each operator of a UNGSF must prepare
and follow for each facility one or more manuals of written procedures
for conducting operations, maintenance, and emergency preparedness
and response activities under paragraphs (a) and (b) of this section.
Each operator must keep records necessary to administer such
procedures and review and update these manuals at intervals not
exceeding 15 months, but at least once each calendar year. Each
operator must keep the appropriate parts of these manuals accessible
at locations where UNGSF work is being performed. Each operator
must have written procedures in place before commencing operations
or beginning an activity not yet implemented.



Boardwalk’s written procedures for conducting operations, maintenance, and emergency
preparedness and response activities were inadequate to assure safe operation in accordance with
section 192.12(c). Specifically, Boardwalk failed to include in its manual, TL1529 Plugging and
Abandoning a Well (5/31/24), a process for the determination of groundwater and hydrocarbon
bearing zones and the condition of the well’s casing across those zones as required by American
Petroleum Institute’s Recommended Practice 1171 (API RP 1171), section 6.7.2, and section
11.2.1 which is incorporated by reference in section 192.12(b)(2).
Section 11.2.1 states that “[t]he operator shall develop and follow procedures for the construction,
operation, and maintenance of natural gas storage wells and reservoirs to establish and maintain
functional integrity.” Section 6.7.2 includes a maintenance requirement that states “[t]he operator
shall determine the location of groundwater and hydrocarbon bearing zones (in addition to the
storage zone) penetrated by the well to be abandoned, and the condition of the well’s casing and
cement across those zones, to prevent communication between any of those zones during and after
plugging of the well.”
Therefore, Boardwalk’s written procedures for conducting operations and maintenance activities
were inadequate to assure safe operation in accordance with section 192.12(c). PHMSA proposes
that Boardwalk must revise its written procedures to address the deficiency outlined above.
2. § 192.12 Underground natural gas storage facilities.
(a) ...
(c) Procedural manuals. Each operator of a UNGSF must prepare
and follow for each facility one or more manuals of written procedures
for conducting operations, maintenance, and emergency preparedness
and response activities under paragraphs (a) and (b) of this section.
Each operator must keep records necessary to administer such
procedures and review and update these manuals at intervals not
exceeding 15 months, but at least once each calendar year. Each
operator must keep the appropriate parts of these manuals accessible
at locations where UNGSF work is being performed. Each operator
must have written procedures in place before commencing operations
or beginning an activity not yet implemented.
Boardwalk’s written procedures for conducting operations, maintenance, and emergency
preparedness and response activities under section 192.12(b) were inadequate to assure safe
operation in accordance with section 192.12(c). Specifically, Boardwalk failed to have an isolation
testing procedure in its manual, Underground Natural Gas Storage, 1171-9.2 Well Integrity
Monitoring (5/31/24), that required personnel to confirm isolation of the well after operating the
master valve and wellhead pipeline isolation valve, as required by API RP 1171, section 9.3.2,
which is incorporated by reference in section 192.12(b)(2).
Section 9.3.2 in API RP 1171 states that “[t]he operator shall test the operation of the master valve
and wellhead pipeline isolation valve at least annually for proper function and ability to isolate the
well.”



Therefore, Boardwalk’s written procedures for conducting operations, maintenance, and
emergency preparedness and response activities under section 192.12(b) were inadequate to assure
safe operation in accordance with section 192.12(c). PHMSA proposes that Boardwalk must
revise its procedures to address the deficiency discussed above.
