Columbia Gas Pipeline Near Interstate 81 in Va. Explodes, Big Fire

click for larger version

Talk about bad luck. On Monday, TC Energy announced it had sold a 40% stake in its Columbia Gas Transmission pipeline subsidiary to Global Infrastructure Partners for $3.9 billion (see TC Energy Sells 40% Interest in Columbia Pipeline to Investor GIP). Yesterday, a portion of the Columbia Gas Transmission pipeline in rural western Virginia–in Shenandoah County near Interstate 81–exploded and caught fire. Fortunately, the blast did not hurt nearby residents, nor were there any injuries among first responders who helped extinguish the fire.

Hilcorp Well Leak in Columbiana OH Fixed, Evacuees Return Home

Yesterday MDN brought you the news that a third-party contractor “struck a well head” on a Hilcorp shale well pad in Columbiana County, Ohio, resulting in a leak that forced the evacuation of 450 people within a mile of the well site (see Columbiana County, OH Evacuates 450 After Hilcorp Gas Well Accident). Good news. The leak has been fixed, the well head replaced, and the evacuees have returned home.

Columbiana County, OH Evacuates 450 After Hilcorp Gas Well Accident

Natural gas well head (sometimes called a Christmas tree)

Roughly 450 people within a one-mile radius of a Hilcorp Energy well pad in Fairfield Township (Columbiana County, OH) were evacuated following a mishap at the pad. Hilcorp says a third-party contractor “struck a well head” on the pad around 9:00 a.m. Tuesday, causing natural gas to leak into the air. What does that mean, that someone struck a well head?

MarkWest Mails Spill Cleanup Notice to Wrong Township in SWPA

tempest in a teapot

In late December 2022, piping at the MarkWest Imperial Compressor Station in Robinson Township, Washington County, PA, froze during Winter Storm Elliot. The frozen line burst, spilling roughly 10,000 gallons of condensate on the ground. On May 23, 2023, MarkWest Liberty Midstream & Resources LLC submitted a Notice of Intent (NOI) to the Pennsylvania Dept. of Environmental Protection (DEP) to clean up soil and groundwater contaminated by the spill. MarkWest’s consultant Tetra Tech sent a copy of the notice to Robinson Township–except they sent it to the WRONG Robinson Township.

Unrelated Explosions at OH Utica Well Pad, WV Brine Plant

click for larger version

We have two explosions and resulting fires to tell you about–neither related to the other, except they happened two days apart and maybe one hour’s drive apart (as the crow flies). The first was an explosion and fire at the Fairmont Brine Processing facility in Fairmont (Marion County), WV, on May 30. The second was an explosion and fire at a Utica Shale well pad owned by Utica Resources near Lore City (Guernsey County), OH, on June 1. Both appear to be accidents. The only injury reported was a minor injury at the Utica well pad site (a worker on-site refused treatment). The main concern was that the brine treatment plant may have stored or handled radioactive material. The WV Dept. of Environmental Protection (DEP) tested and found no radioactive contamination had spread from the fire.

Seneca Tardy in Responding to NOV for Tioga, PA Pad Spillage

The PA Environment Digest Blog has been reviewing the reports filed by Dept. of Environmental Protection (DEP) workers again and noticed a situation at a well pad in Delmar Township, Tioga County. According to DEP reports filed, a Notice of Violation (NOV) was issued to Seneca Resources for a well pad located on DCNR State Forest land last September. Surface water samples from puddles indicate wastewater (brine) from one or more wells spilled onto the ground.

Seneca Well Site Accident in Elk County Spills 63K Gals. of Brine

Most water used for fracking new shale wells in Pennsylvania comes from produced water (i.e. brine)–from other shale wells. Produced water is water from the depths, far below the surface water table, that comes out of a drilled shale well for months and years after the well is drilled. The water is naturally occurring but full of minerals that make it salty–hence the moniker of brine water. While it’s naturally occurring thousands of feet below the surface, produced water is not “natural” when sitting on top of the ground. Unfortunately, Seneca Resources recently experienced a sizable spill of produced water when pumping it to a well the company was fracking on State Game Lands in Jones Township, Elk County.

Fire at Miss. Compressor Station Reduces M-U Flows to Gulf Coast

click for larger version

It’s interesting that a single point of failure, one compressor station, can impact an entire region. Last Friday morning around 1 am, storms moved through Alcorn County, Mississippi. Lightning struck a “vertical gas pipe” at the Columbia Gulf Transmission Corinth natural gas compressor station, releasing and igniting natural gas. One local news station characterized it as a “massive gas fire” that “prompted county-wide response.” The fire burned for over four hours until firefighters could put it out. Some 2.2 billion cubic feet per day (Bcf/d) of Marcellus/Utica molecules flow through that compressor station on their way to the Gulf Coast.

Air Monitors Detect Benzene at Fenceline of Shell Cracker in Monaca

Air monitors at Shell’s ethane cracker plant detected elevated levels of benzene (which can cause cancer in humans) following an April 11 malfunction. However, an industrial hygienist told attendees at Tuesday night’s webinar session with local residents that the levels of benzene detected at the cracker’s community-adjacent fenceline during and after the release were too low to cause “even transient discomfort or irritation.” The highest concentrations found outside the fenceline were “in the parts per billion range.”

PA DEP Withdraws Order to Fix Equitrans Rager Gas Storage Leak

Last November, one of the ten natural gas storage wells at the Equitrans Rager Mountain Gas Storage Area in Jackson Township, Cambria County (in Pennsylvania) began to leak. The well ended up leaking roughly 100 million cubic feet per day (MMcf/d) of gas into the atmosphere (see Equitrans Gas Storage Well in Cambria County, PA is Leaking). It took two weeks (14 days) for the leak to get fixed, after it had leaked roughly 1.4 billion cubic feet into the air (see Storage Well Leak Fix in Cambria County Failed, Leaked 1.4 Bcf). Both the Pennsylvania Dept. of Environmental Protection (DEP) and the federal Pipeline and Hazardous Materials Safety Administration (PHMSA) investigated (see Feds Investigate Equitrans Storage Well Leak in Cambria County, PA). The PA DEP ordered Equitrans to plug several of the 12 wells at the Rager area and ordered the company to make certain (expensive) upgrades to the other wells. Equitrans appealed that order, and the DEP has just backed down.

PA DEP Investigates Bad Odor Coming from Shell Cracker Plant

Shell Polymers Monaca (click for larger view)

The mighty Shell ethane cracker in Beaver County, PA (called Shell Polymers Monaca) has had “issues” getting and staying fully up to speed. Since it officially went online last November, Shell has received six separate notices of violation (NOVs) for exceeding allowable air pollution limits, largely related to repeated flaring episodes (see PA DEP Issues Three More Air Pollution NOVs to Shell Cracker). Sadly, we have another problem to report. Residents living near the plant last week reported a strong, very unpleasant odor coming from the plant. Shell says the odor happened when crews drained a process water tank in preparation for scheduled maintenance and shutdown. The odor lasted for two days.

Chesapeake Makes Slow Progress Cleaning Up Spills at NE PA Pad

There is an ongoing issue with cleanup at a Chesapeake Energy well pad in Bradford County, PA. The Pennsylvania Dept. of Environmental Protection (DEP) showed up at the site to conduct an inspection earlier this year, in January. The DEP inspector found “multiple pools and puddles on the site contaminated with drilling wastewater and possible fracking chemical fluids.” The DEP issued a notice of violation (NOV) for failing to prevent contamination from being discharged on the site. Chesapeake promised to get it cleaned up. Yet, in multiple repeat inspections since then, inspectors have continued to find contaminated fluids on the ground.

9-Day Delay Before PA DEP Inspected Revolution Plant Explosion

Residents living in the vicinity of Energy Transfer’s Revolution Pipeline cryogenic plant in Bulger (Washington County), PA, got a surprise “present” on Christmas morning. Around 7:30 am, residents report hearing an explosion, followed by a fire, at the plant used to separate NGLs (natural gas liquids, including ethane, propane, and butane) from the raw gas stream that flows through the Revolution gathering pipeline (see ET Revolution Cryogenic Processing Plant Explodes in PA on Xmas). Believe it or not, it took the Pennsylvania Dept. of Environmental Protection (DEP) nine full days, until Jan. 3, to actually show up on-site and investigate the situation.

PA Fish & Boat Commission Fines PGE for Muddy Water in Loyalsock

Pennsylvania General Energy (PGE) is constructing a natural gas pipeline, a freshwater pipeline, and facilities to withdraw fresh water at a site along the Loyalsock Creek, north of Montoursville in Lycoming County, PA. The company’s work resulted in a sediment plume that appeared in Loyalsock Creek for several miles downstream of the construction site, caused by the failure of erosion and sediment controls following a heavy rainstorm. The state Dept. of Environmental Protection (DEP) issued notices of violation (NOVs) on three separate occasions from September to November (see PA DEP Dings PGE 3rd Time for Causing Muddy Water in Loyalsock Creek). Yet it was the PA Fish & Boat Commission that just announced a settlement with PGE for creek pollution.

Revolution Processing Plant Xmas Explosion Caused by Leaky Valve

Energy Transfer’s Revolution Pipeline cryogenic plant (click for larger version)

Residents living in the vicinity of Energy Transfer’s Revolution Pipeline cryogenic plant in Bulger (Washington County), PA, got a surprise “present” on Christmas morning. Around 7:30 am, residents report hearing an explosion, followed by a fire, at the plant used to separate NGLs (natural gas liquids, including ethane, propane, and butane) from the raw gas stream that flows through the Revolution gathering pipeline (see ET Revolution Cryogenic Processing Plant Explodes in PA on Xmas). We told you earlier this week the plant has resumed “partial operations” (see Revolution Cryogenic Plant Partially Restarts Following Explosion). While an investigation into the matter is still ongoing, a preliminary report says the explosion occurred when a defective valve released a vapor cloud of natural gas liquids from one section of the plant and ignited.
