WARNING LETTER
VIA ELECTRONIC MAIL TO: restabrook@douglaspipeline.com
May 21, 2025
Mr. Ryan Estabrook
President
Douglas Pipeline Company
901 Castle Shannon Blvd.
Pittsburgh, Pennsylvania 15234
CPF 1-2025-025-WL
Dear Mr. Estabrook:
From February 22 through July 24, 2024 a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code (U.S.C.)
performed an integrated inspected of Douglas Pipeline Company’s (DPC) pipeline facilities in
Shawville, Pennsylvania.
As a result of the inspection, it is alleged that you have committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The item inspected
and the probable violation is:
1. § 192.616 Public awareness.
(a) Except for an operator of a master meter or petroleum gas
system covered under paragraph (j) of this section, each pipeline
operator must develop and implement a written continuing public
education program that follows the guidance provided in the American
Petroleum Institute's (API) Recommended Practice (RP) 1162
(incorporated by reference, see § 192.7).
DPC failed to develop and implement its written continuing public education program.
Specifically, DPC failed to follow its Public Awareness Program (PAP) by not identifying and
providing public awareness messaging to certain entities who engage in excavation within the
counties that DPC operates from 2022 to 2023.



DPC’s PAP section 6.4.1 Method of Determining Target List – Excavators, stated:
[a] list of excavators will be developed using data information from locate requests
during the previous calendar year, or 12-month period preceding the mailing and
Standard Industrial Classification “SIC” designations relating to excavation
activity, as well as other sources that may provide data or resources that assist with
the identification of entities engaged in excavation within the county in which
Douglas operates.
In addition, American Petroleum Institute Recommended Practice 1162, 1st edition Table 2-1.4
outlines the recommendation for distributing public awareness material to excavators at an annual
baseline frequency.
During the inspection, PHMSA selected Glenn O Hawbaker INC from an 811 one call ticket dated
on 1/5/2022 and requested to review DPC’s mail-out records during the period 2022 to 2023. There
were no mail-outs sent to Glenn O Hawbaker INC during the period 2022 to 2023.
PHMSA then requested the one-call tickets for the period 2021 to 2023 and DPC’s distribution
master list of public awareness materials to all its stakeholders for 2022 to 2023. The review of
this documentation indicated that:
• AM Logging LLC had a one-call ticket delivered and had conducted excavation
activity on 11/1/2021 in DPC’s area. However, AM Logging LLC was not identified
as an excavator or other stakeholder in DPC’s master mailing list for 2022 to 2023.
• Glenn O Hawbaker INC had several one-call tickets delivered and had conducted
excavation activities on 11/22/2022 and 03/14/2023 in DPC’s area. However, Glenn
O Hawbaker INC was not identified as an excavator or other stakeholder in DPC’s
master mailing list for 2022 to 2023.
• Keystone Clearwater Solutions had a one-call ticket delivered and had conducted
excavation activity on 02/09/2023 in DPC’s area. Therefore, Keystone Clearwater
Solutions is expected to be listed as an excavator in the 2024 DPC master mailing list.
• United Electric had a one-call ticket delivered and had conducted excavation activity
on 02/28/2023 in DPC’s area. Therefore, United Electric is expected to be listed as an
excavator in the 2024 DPC master mailing list.
• Girard Township had a one-call ticket delivered and had conducted excavation activity
on 11/15/2023 in DPC’s area. Therefore, Girard Township is expected to be listed as
an excavator in the 2024 DPC master mailing list.
Therefore, DPC failed follow its PAP by failing to provide public awareness communications to
known excavators between the years 2022 – 2023 pursuant to compliance with section
192.616(a).
Under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a civil penalty not to exceed
$272,926 per violation per day the violation persists, up to a maximum of $2,729,245 for a related
