In an open letter to Kimberly Bose, secretary of the Federal Energy Regulatory Commission, and reprinted in the Nelson County Times on August 15, 2019, Helen Kimble and Doug Wellman (President and Vice-President of Friends of Nelson) discuss the potential for hazardous landslides in the steeply mountainous areas on the Atlantic Coast Pipeline route in Nelson County. Some of their letter is reproduced below, but go to the Nelson County Times for the full version.
“A recent public presentation on the potential for hazardous landslides in the mountainous areas of Nelson County VA highlighted longstanding concerns about the dangers of routing the Atlantic Coast Pipeline (ACP) through the county’s steep terrain. In this letter, we call your attention to the potential for catastrophic slope failures if ACP overcomes its numerous legal challenges and begins construction. We ask you to consider the following information and its implications for your handling of the Atlantic Coast Pipeline.
“At a public meeting on June 30, geologist Dr. Anne Witt, geohazards specialist with the Virginia Department of Mines, Minerals and Energy (DMME), presented her analysis of the landslides triggered in Nelson County by Hurricane Camille in 1969. In that horrific storm event, 125 people are known to have lost their lives as landslides triggered by severe rainfall swept down valleys in the middle of the night carrying whole families to their deaths.
“The information Dr. Witt presented stems from her ongoing research assessing the landslide potential of steep slopes in Nelson and western Albemarle counties. Her work will contribute to a new Virginia Hazard Mitigation Plan being prepared with support from FEMA and the Virginia Department of Emergency Management. Using LIDAR (Light Detecting and Ranging) technology to map the bare earth beneath vegetative cover, she unveiled a multitude of historical slides on Nelson’s steep slopes. Noting that previous slides are strong indicators of potential future slides, she concluded that Nelson County’s steep slopes have greater landslide potential than had previously been recognized.
“Dr. Witt’s presentation sharpened the concerns raised by a 2017 study of soil and geologic concerns commissioned by Friends of Nelson and Friends of Wintergreen. The final report by Blackburn Consulting Services, LLC — “Report Analysis and Field Verification of Soil and Geologic concerns with the Atlantic Coast Pipeline (ACP) in Nelson County, VA” — was submitted as part of FERC’s EIS review for issuance of the ACP permit. We strongly believe the Blackburn report was not given sufficient consideration in the Commission’s decision.
“Blackburn scientists reviewed the material Dominion submitted to FERC and conducted field analyses of actual conditions in a sample of sites where the pipeline would traverse steep slopes in Nelson County. In their report, Blackburn concluded that: ‘…many of the statements made in the materials submitted to FERC represented gross generalities … [and] … underestimate the true risks that this project imposes on Nelson County and its residents.'”
Key findings of the Blackburn study include [sections on]:
- Landform and soil characteristics
- Mapping soil conditions
- Soil stabilization and erosion control
- Expansion of the corridor
“The permit the commission issued ACP constitutes a recipe for disaster. Dominion’s ‘best in class’ erosion and sedimentation control measures have failed repeatedly in the work they have already done in West Virginia. Similar stabilization measures employed by the Mountain Valley Pipeline builders have led to over 300 violations, legal action by the Virginia Attorney General, and events like sections of pipe carried great distances by floodwaters. MVP is demonstrating what will likely happen if and when ACP begins construction on Virginia’s steep slopes.” [see article below on MVP landslides]
The letter continues, saying
- “Dominion assures concerned citizens that the ACP will be safe. However, according to the Pipeline and Hazardous Materials Safety Administration, 11,993 pipeline failures have been reported in the U.S. over the past two decades.”
- “At present, two federal permits for the ACP have been vacated. Another three federal permits, as well as two state permits, are in the courts or being challenged.”
- “Renewable energy generation and storage are emerging as fully competitive with coal and natural gas on a levelized cost basis”
- “The International Panel on Climate Change’s recent report on climate change — which was soon supported by a report from an interagency panel of U.S. government scientists — made it alarmingly clear that we must quickly shift away from fossil fuels.”
- “Former FERC commissioner Norman Bay warned overbuilding pipelines would likely result in these unnecessary projects becoming ‘stranded assets’ that profit their builders and stockholders at the cost of captive customers and future generations.”
Overwhelming evidence supports the letter’s concluding sentence: “We call on FERC commissioners to bring a halt to this unnecessary and dangerous project.“
