`
`Introduction
`
`On April 30, 2021, David Wertz of Tetra Tech, performed a construction inspection of the Adelphia
`Gateway, LLC (Adelphia) Adelphia Gateway Project (Project) under contract to the Federal Energy
`Regulatory Commission (FERC or Commission) and per the request of the FERC Project Manager,
`Kylee Ferrara.
`
`The Project consists of the construction and operation of a total of about 4.7 miles of new 16-inch-
`diameter pipeline, two new compressor stations (CSs) that together provide a total of 11,250 horsepower
`(hp) of compression, and appurtenant facilities in Delaware and Pennsylvania; the Project also involves
`the purchase, repurpose, and operation of Interstate Energy Company, LLC’s (Interstate Energy) existing
`non-National Gas Act jurisdictional system in Pennsylvania. More specifically, the Project includes the
`following new facilities:
`
`
`
`

`

`
`
`
`
`• construction of an approximately 4.4-mile-long, 16-inch-diameter lateral in Delaware County,
`Pennsylvania extending from the proposed Marcus Hook CS to interconnections with
`Transcontinental Gas Pipe Line Company (Transco) and the Philadelphia Electric Company
`(PECO1; Tilghman Lateral2);
`
`• construction of an approximately 0.3-mile-long, 16-inch-diameter lateral extending from the
`proposed Marcus Hook CS to an existing meter station owned by Delmarva Power and Light
`Company (Delmarva)3 in New Castle County, Delaware (Parkway Lateral);4
`
`• construction of a new 5,625 hp CS in Delaware County consisting of three 1,875 hp natural gas-
`fired reciprocating compressor units (Marcus Hook CS);
`
`• construction of a new 5,625 hp CS in Bucks County, Pennsylvania consisting of three 1,875 hp
`natural gas-fired reciprocating compressor units (Quakertown CS); and
`
`• construction of five new meter stations and other appurtenant facilities.
`
`In addition, Adelphia plans to purchase and repurpose Interstate Energy’s existing oil and natural gas
`pipeline facilities (with minor modifications), including:
`
`• an approximately 84.2-mile-long, 18-inch-diameter mainline pipeline, which is capable of
`transporting either oil or natural gas and which extends from the Marcus Hook Industrial
`Complex to the Martins Creek Terminal in Northampton County, Pennsylvania; 5
`
`• an approximately 4.4-mile-long, 20-inch-diameter mainline, which transports only natural gas,
`which originates in Northampton County and terminates at the Martins Creek Terminal;
`
`•
`
`four meter stations; and
`
`• other appurtenant facilities.
`
`Adelphia proposes to operate the Project in three zones: Zone North A, Zone North B, and Zone South.
`The Project would enable Adelphia to provide up to 250,000 dekatherms per day (Dth/day) of
`bidirectional firm natural gas transportation service in Zone North A; up to 350,000 Dth/day of firm
`transportation service in Zone North B; and up to 250,000 Dth/day of firm tran sportation service in Zone
`South.
`
`Adelphia states that the facilities will be placed into service in two phases . The Zone North facilities
`were placed into service on January 13, 2020. The Zone South facilities will be placed in service
`following the conversion of those facilities. The anticipated in-service timing for the Project is
`November 2021.
`
`
`1 PECO is a public utility owned by Exelon Corporation providing natural ga s a nd electricity to customers in Pennsylvania .
`2 The Tilghma n La teral will a lso interconnect with the Monroe Refinery.
`3 Delma rva is a public utility owned by Exelon Corporation (Exelon) providing na tural ga s a nd electricity to customers in
`Dela wa re a nd Maryland.
`4 The Pa rkway La teral will a lso interconnect with two interstate natural ga s pipelines owned by Columbia Ga s
`Tra nsmission a nd Texas Eastern Tra nsmission Company, LP.
`5 The northern 34.8-mile-long segment is ca pable of transporting either oil or na tural ga s, a nd the southern 49.4-mile-long
`segment was previously used to transport oil only. Adelphia states that, since 2014, the northern segment has transported
`only na tural ga s a nd the southern segment has been inactive.
`
`
`
`

`

`
`
`
`The purpose of the inspection was to determine Adelphia’s compliance with the environmental
`conditions of the Commission’s December 20, 2019 Order Issuing Certificates for the Project and to
`inspect the construction conditions of the Project facilities and rights-of-way (ROWs).
`
`The findings of the inspection were that no instances of noncompliance or problem areas were identified.
`
`A site map and photographic record are presented in this report.
`
`Inspection
`
`On April 30, 2021, weather conditions were clear, with temperatures ranging from the high-50s (°F) to
`high-60s (°F) in the Project area. A total of approximately 1.8 inches of precipitation was recorded in
`nearby Philadelphia during the two weeks before the inspection. Soil conditions were generally wet.
`
`The inspection included the Quakertown CS (Photo Numbers [Nos.] 1 to 3), Paoli Pike Blowdown
`Assembly Valve (BAV; Photo Nos. 4 to 6), Transco Meter Station (Photo Nos. 7 and 8), and Tilghman
`Lateral (Photo Nos. 9 and 10).
`
`Adelphia reported that construction activity at Marcus Hook CS, Quakertown CS, and Transco Meter
`Station had not progressed during previous weeks because a new contractor was being onboarded to
`complete remaining construction. The previous contractor completed removal of its equipment and
`materials from these sites. The new contractor began mobilizing materials and personnel, and was
`already maintaining erosion control devices (ECDs). Construction was active along the Tilghman
`Lateral Phase I, the connecting pipeline between the Tilghman Lateral and Transco Meter Station, and
`the Paoli Pike BAV.
`
`Quakertown CS
`
`Adelphia reported that construction had not yet resumed at the Quakertown CS site. On the western side
`of the Quakertown CS site, additional temporary workspace (ATWS) QCS-01.1 was set up for use
`(Photo No. 1). Equipment mats were placed on top of geotextile fabric. The workspace was clearly
`marked with stakes, and “wetland buffer” and “no refueling” areas were properly identified with signage.
`ECDs were installed along the perimeter of the workspace. “No parking” and “wetland buffer” signage
`was clearly posted along the edge of Permanent Access Road AR-QCS-01, which leads to the office
`trailers, to help prevent unallowed or inadvertent use of this area during construction (Photo No. 2).
`Within the CS yard, construction activity had not yet resumed. Equipment from the previous contractor
`was removed, and some Project materials were staged (Photo No. 3). Site soils from excavation of the
`detention pond were stockpiled and stabilized. No environmental concerns were identified.
`
`Paoli Pike BAV
`
`At the Paoli Pike BAV site, the workspace was clearly marked with stakes and all construction activity
`was within the approved workspace limits. ECDs included chain-link fence reinforced “super” silt fence
`and compost filter sock, which were installed along the perimeter of the workspace (Photo No. 4). The
`reinforced silt fence also functioned as an exclusion fence to keep bog turtle out of the construction
`workspace (bog turtle may be present in the surrounding wetland). Additionally, a bog turtle specialist
`was on-site for bog turtle surveillance during construction and to ensure that the barrier fencing was
`effective. Within the workspace boundaries, equipment mats were overlain on geotextile fabric to
`protect the wetland soils and to provide a stable workspace. The workspace was tidy and well-
`maintained. An excavation around the mainline pipe was stabilized with a trench box, and a section of
`the existing mainline was cut out for the planned installation of the BAV (Photo No. 5). Groundwater
`seeping into the excavation was pumped temporarily into a nearby portable water storage tank that was
`staged within the workspace for later offsite disposal at a treatment facility, according to Adelphia.
`
`
`
`

`

`
`
`
`Adelphia stated that the contractor was currently determining a suitable foundation design for the
`proposed BAV, considering the existing subsoil conditions, and that installation of the BAV was
`expected to be completed in the coming weeks. In general, the workspace and adjacent roadway were
`clean and free of mud and construction debris (Photo No. 6). No environmental concerns were
`identified.
`
`Transco Meter Station
`
`Construction had not yet resumed at the Transco Meter Station site. Exposed soils were temporarily
`stabilized with straw mulch and seed. Meanwhile, stockpiled subsoil was temporarily stabilized with
`erosion control blanket and seed. ECDs were maintained around the perimeter of the site, and there was
`no evidence of sediment transport offsite (Photo No. 7). Construction of the connecting pipeline between
`the Tilghman Lateral and Transco Meter Station was mostly complete . The pipeline was installed
`underneath the roadway tied-in to the Tilghman Lateral and capped near the southern boundary of the
`Transco Meter Station (Photo No. 8). Adelphia reported that the connecting pipeline segment and the
`Tilghman Lateral were hydrotested, cleaned, tested for deformity, and being dried with pressurized air.
`Once dry, the installed pipeline would be filled with nitrogen in the coming days (to prevent corrosion)
`because this portion of the pipeline was expected to be idle while other Project components are
`constructed.
`
`Tilghman Lateral
`
`At the Tilghman Lateral Horizontal Directional Drill (HDD)-1 exit site near Station Number (Sta. No.)
`20+16, pressurized air was being pushed through the pipeline installed along HDD-1 crossing to dry the
`pipeline. According to Adelphia, once drying is complete, the piping will be pressurized with nitrogen
`to prevent corrosion (Photo No. 9). To the east of the completed HDD-1 crossing, within ATWS-TL-
`03a, water used for hydrostatic testing was temporarily stored in a portable water tank. Further to the
`east, spoils excavated from the Paoli Pike BAV site were temporarily stored in roll-off containers. All
`activity was within the approved workspace limits, and no environmental concerns were identified
`(Photo No. 10).
`
`Conclusions and Recommendations
`
`A follow-up letter is not required at this time because no instances of noncompliance were identified.
`Overall, construction was progressing satisfactorily, environmental conditions were acceptable, and no
`environmental concerns were identified. Another inspection is tentatively scheduled for the week of
`May 24, 2021.
