On September 8, at a meeting of the Huntersville
On September 25, multiple news sources reported that the NCDEQ had issued a citation in the form of a notice of violation to the company, stating that samples of groundwater in the area contained levels of chemicals introduced by the spill that were higher than state-acceptable standards.[28] These chemicals included benzene, ethylbenzene, toluene, and xylene, with the former being considered a carcinogen.[29][30] As part of the citation, the company was required to restore the local groundwater to acceptable levels.[27] Additionally, the company was given a deadline of January 20, 2021, to submit a comprehensive report on the incident.[29][27] By the first week of November, the NCDEQ was also asking the company to update its estimate, believing that the 272,580 gallons was still too low of an estimate.[27] By this time, the company had recovered about 267,313 U.S. gal (1,011,890 L) and further efforts were removing an additional 3,000 U.S. gal (11,000 L) to 5,000 U.S. gal (19,000 L) per day.[27] Around the same time, the company removed a portion of the damaged pipe that had caused the spill in order to do metallurgical studies on it.[20][2]
By November 12, the NCDEQ reported that roughly 311,000 U.S. gal (1,180,000 L) had been collected from the site, making it the largest gasoline spill in the state's history.[20] By this time, the company had drilled about 100 wells to identify the extent of the spill and reported that it did not appear to be growing in size past what the company defined as the affected area.[20] By this point, in addition to the gasoline, the company had excavated about 4,000 short tons (3,600 t) of contaminated soil, which they were transporting to the Charlotte Motor Speedway Landfill in Concord, North Carolina.[20] Meanwhile, collected gasoline was sent to a recycling company in Ohio,[20] while contaminated water was sent to a recovery facility in Asheboro, North Carolina.[13] The company dealt with gasoline vapors by using high-powered vacuums and on-site flame oxidizers to burn off the fumes.[13] By December 31, the company estimated that the size of the spill was 492,339 U.S. gal (1,863,710 L).[23]
Early 2021
On January 21, 2021, with the company's submission of its comprehensive, 1,600-page report to the NCDEQ,[8] the official estimate for the size of the spill was approximately 1,200,000 U.S. gal (4,500,000 L),[23][31] making it one of the largest gasoline spills in United States history.[8] Of this amount, the company stated that only about half of this total (661,668 U.S. gal (2,504,690 L)) had been collected.[23] Additionally, the company stated that the estimate could continue to grow as cleanup efforts continued.[2] By February, the company reported that about two-thirds of the estimated 1.2 million gallons of gasoline, as well as 200,000 U.S. gal (760,000 L) of contaminated water, had been collected.[2] At this point, the company had spent about $25 million in cleanup efforts, including $11 million for environmental remediation.[2]
By the end of February, the NCDEQ issued a "Notice of Continuing Violation" to the company and specified 22 "corrective actions" the company needed to take to address the spill.[8] Among these actions, the department required the company to expand the radius of drinking well inspections an additional 500 ft (150 m), install additional deep testing wells to more accurately determine the vertical extent of the oil, and to provide the department with better documentation on how the company determined its estimates on the amount of spilled gasoline.[8] The NCDEQ gave the company a deadline of April 26 to institute the prescribed measures.[8] The department also gave this as the deadline for the company to revise its overall report, which they said was lacking enough information for the department to determine the full impact of the spill.[11] Speaking about Colonial's response to the spill and the estimates they had given to that point, Secretary of Environmental Quality Dionne Delli-Gatti said, "It is unacceptable that for eight months Colonial Pipeline has been unable to provide a reliable accounting of the amount of gasoline released into this community. We will take all necessary steps and exercise all available authority to hold Colonial Pipeline accountable for what has become one of the largest gasoline spills in the country".[11][32]
"(Our) ongoing investigation indicates that conditions may exist on the Colonial Pipeline System that pose a pipeline integrity risk to public safety, property or the environment. The conditions that led to the failure potentially exist throughout the Colonial Pipeline System. Further, Colonial’s inability to effectively detect and respond to this release, as well as other past releases, has potentially exacerbated the impacts of this and numerous other failures over the operational history of Colonial’s entire system. After evaluating the preliminary findings of fact described below and considering the characteristics of the Colonial Pipeline System, as well as the failure history of that system, it appears that the continued operation of the Colonial Pipeline System without corrective measures would pose a pipeline integrity risk to public safety, property, or the environment."
Excerpt from a proposed order submitted by the Pipeline and Hazardous Materials Safety Administration, March 29, 2021.[11]
By April 12,[33] the company stated that 85 percent of the estimated 1.2 million gallons of leaked gasoline had been recovered, though the NCDEQ believed that this estimate was too low considering that the amount of gasoline collected daily had remained at between 3,000 and 5,000 gallons.[11] Additionally, 3D mapping of the area showed that the gasoline had seeped deeper into the ground than initially thought.[11] Around this same time, PHMSA reported that the leak had been caused by a defect in the "Type A" sleeve used in the 2004 repair of the pipe.[11] The agency also noted that this type of repair was highly susceptible to similar failures and that many portions of the pipeline had used this type of repair in the past.[11] As a result, PHMSA issued a proposed order to have the company list all of the similar repairs on their pipes and to improve its leak detection systems.[11] The agency submitted this proposed order on March 29, with the company having 30 days to respond and 90 days after it takes effect to submit a plan to the agency on how they would evaluate the effectiveness of their existing leak detection systems.[11]
In June, the company filed an agreement with PHMSA wherein they would avoid penalties or litigation in exchange for inspecting and improving their leak detection systems and their maintenance protocols.[34] The company would have until October to submit a work plan and timeline, and they would also have to submit quarterly reports to the agency.[34] Failure on the part of the company to meet these requirements could result in fees of $200,000 per day.[35][36]
Late 2021

On July 25, several dozen
By July 31, the company announced that it had recovered 1,225,000 U.S. gal (4,640,000 L), with further cleanup efforts removing an additional 1,000 gallons per day.[40] While this new total surpassed the company's previously stated estimate of 1.2 million, they did not offer an updated estimate at that time.[40] By this point, the company had removed roughly 8,700 short tons (7,900 t) of contaminated dirt and had completely covered the immediate area of the pipeline with fill dirt, and they were working with the local department of parks and recreation on replanting native vegetation in the area.[13] Additionally, the company had dug 281 wells for monitoring and recovering gasoline over a 12-acre (4.9 ha) area.[13] However, the company was ordered by the NCDEQ to construct additional deeper wells to more accurately gauge how far beneath the surface the gasoline had reached.[13] By the one-year anniversary of the spill's discovery, the company had spent over $30 million on the cleanup efforts, which included the cost of connecting four nearby houses to municipal water services and outright buying another three houses, which the company used to house workers.[13] By August 23, the official estimate from the company rose to 1,250,000 U.S. gal (4,700,000 L).[9]
On November 2, the NCDEQ filed a lawsuit against Colonial in the Mecklenburg County Superior Court, alleging that the company had broken state law by failing to update the department regarding the scope of the spill.
2022
In late June 2022, the company and department agreed to a consent decree wherein Colonial would provide additional information to the NCDEQ and also pay nearly $5 million in penalties.[43] This amount included $4.5 million in a civil penalty and an additional $250,000 for costs of the investigation, with additional penalties if the company failed to meet the terms of the decree.[43] By statute, the $4.5 million would go towards the state's education fund.[44] Per the terms of the agreement, the company would have to submit a corrective action plan and schedule, install additional testing wells to see if gasoline had reached bedrock, perform monthly testing and submit a report on the water surface quality, and perform quarterly testing for PFAS.[43] Commenting on the agreement, Environmental Quality Secretary Elizabeth Biser said, "The Consent Order requires Colonial to meet its obligations to the communities impacted by the release, starting with an accurate accounting of the spill volume. This release is on track to be the largest onshore spill in our nation’s history and the order holds Colonial accountable for the necessary cleanup to restore the environment".[43][44] The settlement was approved by Judge Kimberly Best on July 7.[45][46][47]
By the end of June, the company had an updated estimate for the spill of about 1,470,000 U.S. gal (5,600,000 L) of gasoline,[43] and by July 13, they were reporting that about 1.4 million gallons, in addition to 10,000,000 U.S. gal (38,000,000 L) of contaminated water,[48] had been collected.[6] However, on July 22, as per the terms of the consent decree,[49] the company put out a statement saying that they now estimated that at least 2,000,000 U.S. gal (7,600,000 L) had leaked,[50][51][52] prompting regulators in the state to call the spill the largest gasoline spill on land in the history of the United States.[1] According to the company, the pipeline had failed on July 27, 2020, meaning that gasoline had been leaking from the spot for at least 18 days prior to its discovery.[1] The company also stated that they had installed over 385 wells in the area to help remove the gasoline and had identified all areas along their mainline that were found to have used a Type A sleeve and had replaced them with Type B sleeves.[1] The cost of these repairs and replacements was $50 million, while the company had also spent $55 million to this point on the cleanup in Mecklenburg County.[1] They stated that at that time, 1,490,000 U.S. gal (5,600,000 L) had been recovered.[1] According to a July 25 article in EnergyWire, the cleanup is expected to last for several more years.[5]
Aftermath
As the estimates for the amount of gasoline continued to increase over the course of the cleanup, multiple publications made note of the historic size of the spill. In February, after the company gave an estimate of 1.2 million gallons, EnergyWire reported that the spill now constituted "one of the biggest gasoline spills to occur in the United States" as well as "the largest gasoline spill from a pipeline outside of a tank farm storage facility".[2] By July 2022, with the estimate now around 2 million gallons, that same publication called the incident "the largest U.S. gasoline pipeline spill on record".[5] Additionally, local television news broadcasters called it "the largest onshore fuel spill in the nation".[6][53] The spill occurred during a period of increased scrutiny on the safety of oil pipelines in the United States, highlighted by the construction of the Dakota Access Pipeline and concerns expressed regarding its safety.[2]
In March 2021, the two teenagers who initially identified the spill were awarded
