Manhole Mystery: Attempted Breach at Transco Site in Carlstadt, NJ
Early yesterday morning, someone (maybe several someones) tried to get into a restricted area of a Williams Transco pipeline facility in Carlstadt, NJ, by going through the sewer system. Williams says the would-be intruders never made it inside and gas kept flowing normally. But the response was anything but routine. The Bergen County Sheriff’s bomb squad, a K-9 unit, and crime scene investigators all showed up before dawn. As of this writing, nobody has said who these people are, why they were there, or whether anyone has been charged. Read More “Manhole Mystery: Attempted Breach at Transco Site in Carlstadt, NJ”
Williams, the Tulsa company that owns the Transco pipeline (the biggest artery carrying Marcellus/Utica gas to the East Coast), turned in a record third quarter on Monday. But the most important thing for MDN readers came on Tuesday’s earnings call: management admitted that the Third Circuit’s decision to toss New Jersey’s water permit for the Northeast Supply Enhancement (NESE) project “could put at risk our ability to get it online in time for next winter”. Meanwhile, the Southeast side of Transco keeps growing, a new Leidy Line expansion is at FERC, four Williams gas-fired power plants for data centers are rising in Ohio, and Constitution Pipeline? Not one word. 
Last week, the full U.S. Court of Appeals for the Third Circuit said “no thanks” to Williams’ request to reconsider its September ruling that tossed out New Jersey’s water permit for the Northeast Supply Enhancement (NESE) pipeline project. The October 22 order (embedded below) means NESE’s New Jersey water quality certification (WQC) stays vacated (i.e., canceled), and the whole matter goes back to the New Jersey Department of Environmental Protection (NJDEP) for a do-over. And here’s what caught our eye: Williams no longer says the ruling won’t affect its schedule. In its rehearing petition, the company admitted the loss “will delay construction” in New Jersey and could jeopardize NESE’s November 1, 2027 in-service date. So what happens now? Let’s walk through it. 
The Delaware Riverkeeper Network and PennFuture fought for years for the right to challenge Transco’s Regional Energy Access (REA) pipeline permits before Pennsylvania’s Environmental Hearing Board (EHB). They got their wish. Then they lost at the EHB. And yesterday, they lost again in federal court. A three-judge panel of the U.S. Court of Appeals for the Third Circuit unanimously upheld the state Department of Environmental Protection’s (DEP) water permits for the Williams-owned pipeline expansion. The court said the groups never showed that the extra water testing they demanded would have changed a thing. Even better, the court handed down a ruling on Pennsylvania’s Environmental Rights Amendment that could make life a lot harder for anti-drillers going forward. 
Big Green’s second legal attack against Transco’s Southeast Supply Enhancement Project (SESE) just fired its opening shot. On September 18, Sierra Club, Appalachian Voices, Southern Alliance for Clean Energy, and 7 Directions of Service filed their 142-page opening brief in the D.C. Circuit (Case No. 26-1100), arguing FERC’s approval of the pipeline was “arbitrary and capricious” because the agency allegedly ignored evidence that SESE and a second, co-located pipeline would combine to inflict “severe and potentially permanent” damage on streams across Virginia and North Carolina. Construction on SESE has continued the entire time — including through a failed bid by the same groups to freeze it back in June. 
Big Green scored a win yesterday — but not the win they’re telling you they got. On Tuesday, September 8, a three-judge panel of the U.S. Court of Appeals for the Third Circuit vacated the Clean Water Act Section 401 water quality certification (WQC) that the New Jersey Department of Environmental Protection (NJDEP) issued last November for Williams/Transco’s Northeast Supply Enhancement (NESE) project — the $1 billion, 400,000 Dth/d expansion that carries Marcellus gas from Pennsylvania, across New Jersey, under Raritan Bay, and into New York City (see 
Virginia’s environmental cops have hit Transcontinental Gas Pipe Line Company (Transco) with a $179,068.50 civil charge over erosion and sediment control violations on the Pittsylvania County stretch of the Southeast Supply Enhancement (SSE) Project — the single most important new outlet for Marcellus/Utica gas heading south. 
Back in March, we told you about two radical green groups — the Southern Environmental Law Center and the Sierra Club — running to court to block new gas-fired turbines at Georgia Power’s Plant Bowen in Bartow County, Georgia (see 
Last November, New Jersey (and New York) issued a federal Clean Water Act permit to build the Williams Northeast Supply Enhancement (NESE) pipeline project (see 
Williams’ Transco Southeast Supply Enhancement Project (SESE) is a 55-mile, 42-inch-wide pipeline that will run through Pittsylvania County, Virginia, and Rockingham, Guilford, Forsyth, and Davidson counties in North Carolina. Construction for SESE started March 2, 2026, according to FERC filings. Transco (Williams) received its final federal authorization and a Notice to Proceed, and crews mobilized in early spring. Initial activities have included tree felling, installation of acoustic barriers, and test drilling in preparation for blasting. Antis finally gave up trying to block construction of SESE in June (see 
Williams’ Transco Southeast Supply Enhancement Project (SESE) is a 55-mile, 42-inch-wide pipeline that will run through Pittsylvania County, Virginia, and Rockingham, Guilford, Forsyth, and Davidson counties in North Carolina. It will provide natural gas to Duke Energy customers. Big Green sued to overturn a federal water quality permit issued by the U.S. Army Corps of Engineers. Big Green wanted the court to block construction until the full case could be heard. In May, a three-judge panel from the U.S. Court of Appeals for the Fourth Circuit (4th Circuit) rejected arguments Big Green put forward that claimed the Army Corps’ decision was “arbitrary and capricious” and refused to block construction (see
