1975 A gas transmission pipeline exploded and gas burned in Mediapolis, Iowa on January 27. There were no injuries reported.

1975 In March, a leak was discovered in a 14-inch petroleum products pipeline in Mecklenburg County, North Carolina. Plantation Pipeline began efforts to recover the spilled petroleum. From that time through June 1983, approximately 2,022 barrels of spilled petroleum products were recovered from standpipes at the leak site. Remediation efforts stopped in October 1984. Later tests raised questions on the possibility of not all of the spill products were recovered.

1975 A 12-inch crude oil pipeline ruptured near Harwood, Missouri, on March 26. Heavy rain slowed the cleanup.

1975 A natural gas liquids (NGL) pipeline ruptured due to previous mechanical damage, at Devers, Texas. 4 people were killed in a following vapor cloud fire. The pipeline had been damaged when a valve was installed on the pipeline. (May 12, 1975)

1975 An explosion in June 1975 at a home in East Stroudsburg, Pennsylvania, was caused by natural gas leaking into the home from an open main in the middle of the street. One person was killed. In 1973, workers hired by the gas company had falsified records showing the main had been closed.

1975 On June 11, a leaking pipeline for the Alyeska Pipeline Service Company was found to have spilled about 60,000 gallons of crude oil at a construction camp in Alaska. That pipeline had been noticed leaking before, but, previous repair efforts had failed.

1975 An LPG pipeline ruptured near Romulus, Michigan, due to previous mechanical damage to the pipeline, and over pressurization from operator error, caused by closing a valve against a pumping pipeline, at a storage facility. Nine people were injured in the following vapor cloud fire. Flames 500 feet (150 m) high engulfed a 600-foot (180 m)-diameter area, destroyed four houses and damaged three others, burned 12 vehicles, and consumed 2,389 barrels (379.8 m³) of propane. (August 2, 1975)

1975 An ammonia pipeline ruptured in Texas City, Texas on September 3. 47 people needed medical treatment for ammonia exposure.

1975 On September 7, a gas gathering pipeline failed due to internal and external corrosion near Kilgore, Texas. Unodorized natural gas liquids from leak were ignited by an automobile, killing 5 people.

1975 On September 19, flooding along the Amite River in Louisiana caused a 12-inch propane pipeline to break, releasing about 743,000 gallons of propane.

1975 On October 13, employees at a gas processing plant at Goldsmith, Texas heard leak gas, and investigated. Before the leak could be found, a 12-inch pipeline there exploded, killing 3 of the crew, injuring 2 others, and causing extensive plant damage.

1975 On December 18, a failed pressure relief device caused cracks in storage tanks supporting the Trans-Alaskan Pipeline System, leaking about 600,000 gallons of crude oil in Prudhoe Bay, Alaska.

1976

1976 On January 7, a repair crew working on natural gas gathering compressor station at Cedardale, Oklahoma, opened the wrong valve in an attempt to increase gas flow. Natural gas & Natural Gas Liquids flow out of an open 12-inch pipeline, and were ignited by an open flame heater. 5 of the crew were killed, and 2 seriously burned.

1976 On January 10, a gas leak at the Pathfinder Hotel in Fremont, Nebraska, exploded, killing 23 people. A compression coupling on a gas line had pulled apart, causing gas to leak into the Hotel's basement.

1976 A MAPCO LPG/NGL pipeline ruptured near Whitharral, Texas, leading to vapor cloud fire that killed one, severely burning 4 others who later died, destroyed two homes, and burned an area about 400 yards wide. A Low Frequency Electric Resistance Weld (LF-ERW) seam failure is suspected for the failure. From January 1968 to the date of the Whitharral accident, 14 longitudinal pipe seam failures had occurred on that pipeline system, which resulted in 6 other fatalities, and the loss of over 60,000 barrels (9,500 m³) of LPG.(February 25, 1976)

1976 An improperly assembled compression coupling failed on a gas distribution line in Phoenix, Arizona on February 8, causing a house explosion that killed 2 people.

1976 On March 2, an 18-inch Gulf Oil pipeline failure spilled about 21,000 gallons of crude oil into the Wisner Wildlife Area in Louisiana. There were no initial reports of wildlife being affected.

1976 On March 16, a 6-inch ARCO pipeline failed near Tilden Township, Pennsylvania, spilling gasoline into a stream.

1976 On March 27, a two-story building in Phenix City, Alabama, exploded and burned from a gas leak. The explosion and fire killed the six persons in the building. The NTSB found that gas at 20-psig pressure had leaked from a cracked, 3-inch cast iron gas main.

1976 A front loader hit a Standard Oil of California (now Chevron Corporation) 8-inch petroleum products pipeline in Los Angeles, California, during a road widening project along Venice Boulevard. 9 people were killed, a plastic factory was destroyed, and other serious property damage occurred. (June 16, 1976)

On August 8, a house exploded from gas migrating through the soil, from a broken 4 inch gas main, in Allentown, Pennsylvania. 26 minutes later, gas then exploded in another house, causing a brick wall & part of the street to collapse. 2 firefighters were killed, 14 people injured, and 4 buildings destroyed.

1976 A road grader hit a 20-inch gas transmission pipeline near Calhoun, Louisiana. Six people were killed in the ensuing fire, 6 families were left homeless, and a mobile home and 2 houses were destroyed. (August 9, 1976)

1976 On August 13, a flash fire in the basement of a house in Bangor, Maine, occurred while a gas company crew was checking for the cause of low gas pressure at the home. The fire killed one gas company employee, burned two other employees, and caused minor damage to the house. One of the crew was using a match to light the basement of the home, and another crew member was smoking when the fire started.

1976 On August 29, an explosion and fire destroyed a house at Kenosha, Wisconsin. Two persons were killed, four persons were injured, and two adjacent houses were damaged. The destroyed house was not served by natural gas. However, natural gas, which was escaping at 58 psig pressure from a punctured 2-inch plastic main located 39 feet (12 m) away, had entered the house through a 6-inch sewer lateral that had been bored through to install the gas line.

1976 On September 10, sewer work and heavy equipment caused soil subsidence on a 6-inch cast iron gas pipe in Blue Island, Illinois, resulting in the pipe breaking in 4 places. Gas then migrated into a building, that later exploded, killing 1 person, and, injuring 10 others.

1976 On November 28, an 8-inch Sunoco pipeline began leaking in Toledo, Ohio, spilling about 1,000 barrels of gasoline, forcing a major road closure. There were no injuries.

1976 An explosion and fire at a gas pipeline compressor station in Orange Grove, Texas killed one plant worker, and injured another on December 6.

1977

1977 On January 2, a gas pipeline ruptured and burned near Nursery, Texas. Some power poles were destroyed, but there were no injuries.

1977 On January 5, in Fairview, New Jersey, a circumferential break on a 6-inch cast iron gas pipe. The released gas then migrated under frozen soil & a sidewalk, into an area under the floor of a building. The gas later was ignited by an unknown source, causing an explosion that killed 1 person, injured 13 others, and destroyed 3 buildings.

1977 In Baltimore, Maryland on January 13, a 4-inch cast iron gas line suffered a circumferential break. The gas migrated under frozen soil and pavement into nearby rowhouses, and was likely ignited by an oil burned motor. One person was killed.

1977 On January 18, an 18-inch steel gas main failed and leaked into an electrical and telephone conduit in New Bedford, Massachusetts. Three explosion followed, destroying 5 buildings, and breaking windows nearby. Improper pipeline construction techniques were the cause of the failure. There were no injuries.

1977 A gas pipeline exploded and burned in Stockton, California on February 4. Another gas pipeline fire had occurred nearby 4 days earlier. There were no injuries.

1977 On May 20, fire broke out at a MAPCO pipeline pumping stations and Terminal in Ogden, Iowa, threatening 4 propane storage tanks for a time. There were no injuries.

1977 In June, a Williams Partners pipeline terminal near Lawrence, Kansas spilled about 33,600 gallons of gasoline. the next spring, a rancher nearby was still having gasoline entering a creek on his property.

1977 An explosion on July 8 at Trans-Alaska Pipeline System Pump Station No. 8 kills one worker, injures 5 others, and destroys the pump station. Over $2 million in damage was done. A US House of Representatives Committee later announced the cause was workers not following the proper procedures, causing crude oil to flow into a pump under repair at the time.

1977 On July 19, the Trans-Alaska Pipeline System pipeline was shut down for the 4th time in a month, when it was hit in a valve by a front loader. More than 40,000 US gallons (150,000 L) of crude oil was spilled.

1977 A 12-inch propane pipeline ruptured near Ruff Creek, in Greene County, Pennsylvania, from stress corrosion cracking, on July 20. The resulting propane vapor cloud ignited, when a truck that was driven into the cloud stalled, then created a spark, when it was restarted. The two men in the truck were killed, as well as 57 head of cattle, along with destruction of power lines and wooded areas. Subsidence of underground coal mines in the area may have hastened the failure.

1977 A cast iron gas main broke in Cherokee, Alabama on July 30. Gas migrated into a home through a recently back filled sewer line trench, and exploded 5 days later.

1977 In August, a car drove through leaking liquid from a petroleum pipeline in Lakewood, California. The pooled liquid appeared to be mud, but it exploded and burned, injuring a woman in the car.

1977 On August 9, natural gas under 20 psi pressure entered a 6-ounce per square inch gas distribution system in El Paso, Texas, over pressuring 750 gas customer customers. Numerous small fires resulted from this. The cause was an error during gas pipeline replacement.

1977 On August 15, crude oil spilled at Trans-Alaska Pipeline System Pump Station No. 9. There was no fire, but a fire or explosion at that station could have shut down that pipeline, since Pump Station No. 8 was out of service from the previous month's accident there. This was the seventh accident on this pipeline since the start up of the Alaska pipeline on June 20, 1977. The NTSB released three recommendations on September 9, 1977, to correct certain design and operating deficiencies in the pump rooms of each station of the Alyeska system.

1977 A gas transmission pipeline exploded, forcing hundreds to evacuate in Columbus, Indiana on August 26. There was no fire or injuries.

1977 On September 5, 2 brothers in a moving truck drove into a vapor cloud from a leak at a gas compressor plant in New Cuyama, California, igniting the cloud. One was killed immediately, and the other died 11 days later.

1977 On September 10, a pipeline rupture spilled 69,000 US gallons (260,000 L) of gasoline into a creek in Toledo, Ohio. Corrosion of the pipeline caused the failure.

1977 A gas line inside a building in San Francisco, California leaked and exploded, injuring 7 and heavily damaging that building. Gas repair crews were working on the line at the time.

1977 On October 12, a bulldozer ruptured a propane pipeline near Albany, Georgia, causing nearby train traffic to be halted. The bulldozer engine was left running, nearly igniting the vapors.

1977 On October 30, a bulldozer hit a gas pipeline in Shreveport, Louisiana. The gas ignited, causing a 100 foot tall flame, injuring 4 people.

1977 A backhoe being used to install a pipeline hit an adjacent 6-inch propane pipeline on November 21 in Hutchinson, Kansas. Fire broke out, but there were no injuries.

1977 Construction workers punctured a 12-inch gas pipeline in Atlanta, Georgia, with an I-beam on December 1. No fire or explosion followed, but thousands of people were evacuated from nearby buildings.

1977 A compression coupling joint between a plastic and a steel gas line pulled apart in Lawrence, Kansas on December 15. The gas migrated into 2 buildings, and exploded, killing 2 people, and injuring 3 others.

1978 On February 26, a 16-inch Cities Service Gas pipeline ruptured near Lecompton, Kansas, causing natural gas shortages in the area.

1978 An improperly plugged gas line leaked into service vault in Oklahoma City, Oklahoma at a shopping center, overcoming 5 gas company workers on March 29. Four of the repairmen died of asphyxiation. None of the repair crew had respirators at the job site.

1978 A gas company crew in Mansfield, Ohio accidentally tied a high pressure gas main into a low pressure gas main on May 17. Much higher gas flames in gas appliances caused damage in 16 homes, and about 2,000 gas meters were shut off during the incident.

1978 On June 12, a 10-inch gas pipeline was hit by a construction crew, in Kansas City, Missouri. Almost 2 hour later, escaping gas ignited, causing burns to 2 men from a crew trying to fix the pipeline leak.

1978 A MAPCO LPG pipeline in Donnellson, Iowa ruptured from past mechanical damage and improper lowering for road improvements. The vapor cloud ignited several minutes after the rupture. Three people were killed and 2 others severely burned. The pipe failed at a dented and gouged area not seen during the original construction, or lowering for road work a few months before. A hydrostatic test on this pipeline after the accident caused failures at 2 other dented & gouged section, and 15 ERW seam failures in 117 miles. (August 4, 1978)

1978 On August 7, in Lafayette, Louisiana, natural gas at 15 psig pressure escaped from a corrosion leak in an inactive 1-inch steel service line and migrated beneath a concrete slab and into a building where it ignited. The resulting explosion and fire injured six persons and destroyed the building and its contents.

1978 On August 14, a coal digging crew in Cairo, Missouri hit a MAPCO LPG pipeline with a backhoe. The gas ignited about 2 hours later, as digging crews were still working nearby. 1 worker was burned, along with the backhoe, a bulldozer, and a diesel fuel tank.

1978 On August 28, natural gas, which had escaped from a circumferential fracture in a socket heat-fusion coupling on a 2-in. polyethylene (PE) main, operating at 40-psig pressure, migrated beneath a one-story house in Grand Island, Nebraska, exploded, and then burned. One person was injured; the house was destroyed; and three adjacent houses were damaged.

1978 About 7,600 US gallons (29,000 L) of gasoline were spilled in Hampton, Pennsylvania on August 30. Workers boring for a sewer line had hit a fuel pipeline. Later, the 2 construction firms responsible were fined only $500 each.

1978 A pipeline feeding a Strategic Petroleum Reserve storage cavern ruptured in Hackberry, Louisiana on September 22, causing a large fire.

1978 A 30-inch United Texas Transmission gas pipeline in Brookside Village, Texas ruptured and exploded, killing five people, and injuring 43 others. Seven mobile homes were also destroyed. The blast was felt 35 miles away. (October 24, 1978)

1978 On October 30, a pickup truck with 2 women inside drove into an unseen gas cloud from a leaking gas gathering pipeline in Preston, Oklahoma, triggering explosions and a fire, killing the 2 women. 3 homes were also damaged. Flames from the fire reached 200 feet high.

1978 An Amoco crude oil pipeline leaked into the Farmington Bay Waterfowl Management Area west of Farmington, Utah on November 7. About 105,000 gallons of crude were spilled. The rupture was caused by pumping against a valve that had been closed for earlier pipeline maintenance.

1979

1979 A ruptured 2-inch gas line leaking caused a home to explode in Spokane, Washington on January 6, killing the homeowner.

1979 On January 16, an explosion and fire destroyed five commercial buildings and damaged several other buildings in London, Kentucky. Two persons were injured. External corrosion was suspected as the cause. A prearranged pressure increase in the pipeline was also a factor.

1979 On January 18 in Hocking County, Ohio a high pressure pipeline ruptured, killing a line repairman, and a supervisor. 6 other line repairman were also seriously injured.

1979 On February 7, a Colonial Pipeline stubline ruptured in Hamilton, Tennessee, spilling about 152,000 gallons of petroleum product. The cause was from imprper backfill of soil around the pipeline during its construction.

1979 On March 2, at Alyeska Pipeline Service Company, Pump Station #6 located near the Yukon River in Alaska, the topping unit producing turbine fuel experienced a flame out of the flare stack which burns flammable tail gas from the unit. Automatic ignition apparatus did not function due to the extreme low temperature of -25F. A safety professional on staff was tasked with climbing the stack and re-igniting the flare manually. Once ignition was established, and before the safety professional could climb down from the top catwalk platform, station management ordered the combustion blower to be turned on and tail gas pressure to be increased from 3psi to 11psi. The action resulted in a surge through the knock out drum at the base of the stack, causing residual oil and naphtha to be blown up the stack, covering the top catwalk and approximately the top 60 feet of the stack in burning petroleum. The safety professional was severely burned and fell through the stack main access ladder components and iron work 115 feet to the ground. The occurrence did not result in a fatality, however, fire damaged the stack and petroleum contaminated the surrounding base area.

1979 An 18-inch natural gas transmission pipeline failed underneath the Florida Turnpike in West Palm Beach, Florida, resulting in a 2-hour road closure.

1979 On April 18, a 24-inch natural gas transmission pipeline pulled out of a compression coupling, during a line-lowering project under Iowa State Highway 181, in a rural area, near Dallas, Iowa. Within seconds, the natural gas ignited and burned a 900-foot (270 m) by 400-foot (120 m) area. Two cars, a pickup truck, and a trailer housing construction equipment were destroyed. A backhoe was damaged and windows were broken in a nearby farmhouse. Five of the eight injured workers were hospitalized. The gas company's accident records indicated that this 24-inch pipeline had experienced 12 previous failures since it was constructed.

1979 On April 20, a series of explosions, and a fire, struck a Sunoco pipeline terminal in Toledo, Ohio. Some nearby residents fled their homes, and telephone service was disrupted.

1979 On May 11, 2 explosions, and a following fire, killed 7 people, injured 19 others, and destroyed 3 buildings, in Philadelphia, Pennsylvania. Soil erosion under an 8-inch cast iron gas main caused the main to break and release gas.

1979 On May 13, a 36-inch Colonial Pipeline ruptured, releasing 336,000 US gallons (1,270,000 L) of fuel oil that damaged vegetation, and killed fish, near Spartanburg, South Carolina. Cracks made in the railroad shipping of the pipe before installation were the cause.

1979 On May 19, tank truck drivers waiting at an Amoco terminal heard a bang, then saw a 3-foot side stream of gasoline pour down a nearby hillside in Pittsburgh, Pennsylvania. Train traffic on 2 nearby rail lines had to be stopped during the cleanup.

1979 A "spud" dropped by a pile driving barge in the Gulf of Mexico near Pilottown, Louisiana ruptured a 4-inch natural gas pipeline on June 5. The escaping gas ignited, and seriously burned the barge. 4 crew members went missing and were presumed dead.

1979 On June 10, the pilot of a helicopter reported sighting oil on the surface of the Atigun River near the route of the Trans-Alaska Pipeline System's 48-inch crude oil pipeline. Repair crews found a 7-inch crack which passed through a longitudinal weld. Five days after the first leak, at 3:15 p.m. on June 15, the pilot of an Alyeska helicopter on a routine surveillance flight reported a leak north of pump station No. 12 near the Little Tonsina River. A crack near a wrinkle in the pipe was found there. The June 10 spill resulted in a release of approximately 1,500 barrels (240 m³) of crude oil; the June 15 leak resulted in a release of approximately 300 barrels (48 m³) of crude oil; these losses were estimated by Alyeska personnel at the leak site. The spills were too small to be verified by the Alyeska metering system.

1979 A crack in a wrinkled section of the Trans-Alaska Pipeline System pipeline occurred at Pump Station 12 on June 15 on the south end of that pipeline in southern Alaska. About 1,000 barrels of crude oil were spilled.

1979 On June 16, operator error at Colonial Pipeline caused a prior to installation rail shipping induced crack of 36-inch pipeline to rupture in Greenville County, South Carolina. 395,000 gallons of fuel oil were spilled, causing vegetation, fish, & wildlife kills.

1979 A leaking pipeline released gasoline in Granger, Indiana, causing the evacuation of 400 people on July 3.

1979 An anchor handling boat, PETE TIDE II, damaged an unmarked gas pipeline with a grappling hook offshore from New Orleans, Louisiana. Two of the crew were missing and presumed dead in the fire that followed. (July 15, 1979)

1979 On July 25, an explosion and fire destroyed a duplex apartment house in Albuquerque, New Mexico. Two persons were killed, and two persons were hospitalized for burns; adjacent houses were damaged. Earlier in the day, a crew from Mountain Bell Telephone Company (Mountain Bell) had been using a backhoe at the intersection of Bridge Boulevard and Atrisco Road to locate a telephone cable. The backhoe snagged a gas service line but the fact that it was pulled from a 1-inch coupling under the house was not discovered at that time.

1979 A 34-inch Lakehead (now Enbridge) pipeline ruptured near Bemidji, Minnesota, leaking 10,700 barrels (1,700 m³) of crude oil on August 20. The pipeline company initially recovered 60 percent of the spilled oil. Later in 1988, the Minnesota Pollution Control Agency required Lakehead to extract more oil using new technology; removal continued on, with studies still underway in the area.

1979 On August 20, a bulldozer operating near Orange, Texas, was being used to clean a farm drainage ditch. The corner of the blade cut into a propane line, which crossed beneath the ditch. Propane at 350 psig escaped and was ignited within seconds. The resulting fire killed one person, injured another, and caused considerable property damage.

1979 A crude oil pipeline ruptured and spilled oil into a creek new Walnut Grove, Missouri on August 25. 2 miles (3.2 km) of the creek were contaminated, and 32,000 fish killed.

1979 On September 4, the M/V WHITEFACE struck a high-pressure gas pipeline on Lake Verret, near Pierre Part, Louisiana. A resulting explosion killed a crewman aboard the vessel.

1979 On October 6, an explosion caused by liquefied natural gas (LNG) vapors destroyed a transformer building at the reception facility of the Columbia LNG Corporation, Cove Point, Maryland. Odorless liquefied natural gas leaked through an inadequately tightened LNG pump seal, vaporized, passed through approximately 210 feet (64 m) of underground electrical conduit and entered the substation building. One person was killed, and one person was seriously injured. Damage to the facility was estimated at about $3 million. The fire hydrants and deluge water spray system were inoperable after the explosion because the water main that supplied the system was broken at a flange above ground inside the substation.

1979 On October 24, an explosion and fire destroyed the county clerk's office building and the adjoining courthouse building, gutted a connecting building which was under construction, and damaged the adjacent houses in Stanardsville, Virginia. Thirteen persons were injured and property was damaged extensively. The following NTSB investigation revealed that natural gas had leaked from a break in a 1 1/4-inch coated steel service line, which had been snagged by a backhoe which was being used to dig a footing for an addition to the county clerk's office building.

1979 On October 30, a natural gas explosion and fire demolished a townhouse in Washington, D.C., and damaged nearby buildings and cars. No one was inside the townhouse at the time, but three persons in a stopped car were injured when debris from the explosion shattered a car window. After the accident, an inspection of the gas service line that served the townhouse revealed that it had been struck by excavating equipment.

1979 A natural gas transmission pipeline exploded in West Monroe, Louisiana on November 11, causing 3 subdivisions to be evacuated, and creating a crater 70 feet wide and 20 feet deep. There were no injuries. A gas pipeline explosion had taken place nearby 8 years before.

1979 A 12-inch Amoco pipeline broke on December 11 near Waverly, Missouri, spilling about 8,400 gallons of crude oil. Temperature changes were blamed for the joint failure on the pipeline.

1979 On December 16, military police at Marine Corps Base Quantico discovered fuel oil leaking into the Potomac River, near Chopawamsic Island. A leaking Plantation Pipeline 12 inch pipeline was the source, spilling between 5,000 and 10,000 gallons of fuel oil.

1980s

1980 On January 2, crude oil leaked from a fractured 22-inch pipeline, at a levee crossing, in Berwick, Louisiana. At 9:54 a.m., the crude oil ignited. One person was killed, one person was injured, and six homes were either destroyed, or, damaged. The pipeline's monitoring system failed to detect a loss of over 1,800 barrels (290 m³) of oil. A defective sleeve weld cause the pipeline to fail.

1980 On January 30, an 8-inch refined petroleum products pipeline, owned by The Pipelines of Puerto Rico, Inc., was struck and ruptured by a bulldozer, during maintenance work on a nearby waterline, in the Sector Cana of Bayamon, Puerto Rico, about 10 miles (16 km) southwest of San Juan. Gasoline from the rupture sprayed downhill, and ran off into a small creek. About 1 1/2 hours later, the gasoline vapors were ignited by an undetermined source and exploded; the subsequent fire killed one person and extensively damaged 25 houses and other property.

1980 On February 21, an explosion and fire destroyed four stores in a shopping complex and severely damaged an adjoining restaurant in Cordele, Georgia. Of the eight persons who were injured, three died later as a result of their injuries. Property damage was extensive. The NTSB investigation of the accident has revealed that natural gas leaked from a 1-inch steel service line, which had been pulled from a 1-inch compression coupling from a backhoe working in the area, and migrated under a concrete slab floor and into a jewelry store where it was ignited by an unknown source.

1980 A Colonial Pipeline Dispatcher ignored established procedures for dealing with a pressure surge, causing a double rupture of a 32-inch steel petroleum products pipeline on March 6. One break, where the pipe had been thinned by corrosion in a casing under a road, caused the release of 8,000 barrels (1,300 m³) of aviation-grade kerosene adjacent to route 234 near Manassas, Virginia. Before being fully contained, the kerosene had flowed into Bull Run River, and had entered the Occoquan Reservoir, a source of drinking water for several northern Virginia communities. The other break, where a crack in the pipe wall initiated during rail shipment of the pipe from the steel mill finally propagated to failure, caused the release of 2,190 barrels (348 m³) of No. 2 fuel oil near Locust Grove, a rural area in Orange County, near Fredericksburg, Virginia. Before being fully contained, the fuel oil had flowed into the Rapidan River and then into the Rappahannock River, a source of drinking water for the City of Fredericksburg.

1980 Sabotage during a labor strike was suspected in a gasoline pipeline explosion in Marcus Hook, Pennsylvania on March 7. The following fire burned for about 17 hours.

1980 On April 16, gasoline at a Williams Companies pipeline terminal in Roseville, Minnesota, sprayed from the fractured cast-iron base of a station booster pump at 72 psig pressure, vaporized, and exploded after it was ignited by the spark of an electric switch in the mainline pump control room 50 feet (15 m) downwind of the booster pump. One man was killed, 3 others injured, and extensive damage was done to the terminal. About 3,500 barrels (560 m³) of petroleum products burned and property damage was estimated at $3 million.

1980 On May 27, near Cartwright, Louisiana, an anhydrous ammonia pipeline was struck by a bulldozer, which was being used to prepare a well site, and the pipeline ruptured. Over 100 people were evacuated from the area.

1980 On July 23, a Tennessee Gas Pipeline 30 inch line burst in Clay City, Kentucky, spraying dirt and rocks in the area, damaging 2 homes. There was no fire.

1980 A road grader ruptured an NGL pipeline in Aurora, Colorado on August 11. Firefighters had barely evacuated residents in the area when the vapors exploded, burning one firefighter.

1980 On September 3, a Mid-Valley Pipeline Co. line was ruptured by pipeline work, in Cygnet, Ohio. Efforts to contain the crude were unable to prevent some of it from entering the Portage River.

1980 An oil pipeline ruptured and burned while it was being repaired at an oil storage Terminal in Piney Point, Maryland on September 12, 1980. One worker was killed, and 5 others injured in the fire.

1980 On October 9, a 2-inch compression coupling located on the upstream side of a gas meter set assembly in the boiler room of the Simon Kenton High School in Independence, Kentucky, pulled out of its connection with a 2-inch gas service line. Natural gas at 165-psig pressure escaped through the 2-inch opening and, seconds later, exploded and burned. A basement wall was blown down, an adjacent classroom was damaged, and one student was killed. About 30 minutes later, a second explosion occurred, which injured 37 persons and extensively damaged the school. The gas main was being uprated at the time.

1980 A bulldozer digging a ditch for a new pipeline hit a 16-inch crude oil pipeline near San Ysidro, New Mexico on October 22. The operator was fatally burned.

A woman and her 7-year-old daughter suffered fatal burns, at least two others were injured, and many homes damaged or destroyed. Confusion by the pipeline company led to a delay in shutting down the pipeline. Electrical resistance welded (ERW) seam failure caused the rupture. Prior to this accident, this pipeline, installed in 1957, had 16 seam failures during hydrostatic testing, and 7 seam failures during operations until 1984. In 1984, 16 more seams failed during a hydrostatic test. Problems with cathodic protection were also noted before the 1986 accident. During a hydrostatic test of this pipeline following the accident, 3 ERW seams failed. Studies of available data by OPS staff in early 1988 showed that ERW seams have been involved in 145 service failures in both hazardous liquid and natural gas pipelines since 1970 to early 1988, and that of these failures, all but 2 occurred on pipe manufactured prior to 1970.

1994 In January, a pipeline ruptured, dumping almost 162,500 US gallons (615,000 L) of oil in a river, the Marais des Cygnes River in Osawatomie, Kansas. In addition to a $804,700 fine, BP Amoco agreed to spend at least $145,300 on a supplemental environmental project involving reconstruction improvements to Osawatomie's water intake.

1994 On January 16, a pipeline burst, at a tank farm in Saint Louis, Missouri, spilling gasoline during a transfer operation. The company knew that some gasoline was missing, but, waited until January 18 to confirm and report the loss. About 240,000 gallons of gasoline was spilled, with about 100,000 gallons entering the Mississippi River.

1994 The January 17 Northridge earthquake caused a crude oil pipeline to crack near Piru, California, spilling about 173,000 gallons of crude into the Santa Clara River. The cleanup took more than 600 workers six weeks to complete and cost more than $14 million.

1994 On February 1, the third explosion in 7 years hit a LPG/NGL pipeline Terminal in Iowa City, Iowa. 11 workers at the Terminal escaped injury, and 6 families within 1 1/2 miles of the Terminal were evacuated. The 2 previous explosions were in 1987 and 1989.

Edison, New Jersey natural gas explosion: March 23, 1994, previous damage caused a 36-inch diameter natural gas transmission pipeline to rupture at Edison, New Jersey. Several apartment buildings and a number of automobiles were destroyed in the massive fire. One woman died of a heart attack, and at least 93 others had minor injuries. Delays in shutting off one of the pipeline's valves was cited as contributing to the damage.

1994 On May 8, a Sunoco pipeline leaked gasoline in Indiana County, Pennsylvania, forcing the evacuation of 50 homes. About 537 barrels of gasoline were spilled.

1994 On June 2, a Koch Industries pipeline spilled gasoline in Wichita, Kansas. About 79,000 galons were spilled, and, some of it caused interruptions in local water supply.

1994 A 2-inch steel gas service line that had been exposed during excavation separated at a compression coupling about 5 feet (1.5 m) from the wall of a retirement home in Allentown, Pennsylvania on June 9. The escaping gas flowed underground, passed through openings in the building foundation, migrated to other floors, and exploded. The accident resulted in 1 fatality, 66 injuries, and more than $5 million in property damage.

1994 A residents near O'Fallon, Missouri detected a petroleum smell, early on September 22. The local Fire Department was called several hours later, and noticed an oily mist in the area, and found a leaking pipeline. The owner of the 10-inch petroleum products later claimed the spill volume was less than 1,000 US gallons (3,800 L), but later calculations and batch volume measurements indicate a spill of 29,000 to 37,000 US gallons (140,000 L). EPA officials later admit someone lied about the spill volume. Over the next 10 years, 8 attempts at remediation were made, before the O'Day Creek was cleaned of all petroleum products.

1994 On October 8, a lightning strike shut a valve on a Koch Industries crude oil pipeline crossing Gum Hollow Creek, while oil was flowing, triggering a pressure buildup that ripped a 50-square-inch hole in a section of the pipe that was already weakened by corrosion. Pipeline employees — unaware of the rupture in the pipe — turned the pipeline pumps back on after the pipeline shut down automatically, sending oil pouring into the creek for about an hour. The spill created a 12-mile (19 km)-long slick on Nueces and Corpus Christi bays along the Texas Gulf Coast. Nearly seven years later, delicate coastal marshes that serve as a nursery for shrimp, flounder, crabs and other marine life had not fully recovered. The estimated spill size was 2,151 barrels (342.0 m³), but that was debated as being too small a size. The pipeline eventually agreed to pay more than $45 million in damages. Koch reported to PHMSA that the spill cost zero dollars in property damage.

1994 In October, record high flooding along the San Jacinto River in Texas lead to the failure of 8 pipelines crossing that river. Due to the flooding many other pipelines were also undermined. More than 35,000 barrels (5,600 m³) of petroleum and petroleum products were released into the river. Ignition of the released products resulted in 547 people receiving (mostly minor) burn and inhalation injuries. Spill response costs exceeded $7 million, and estimated property damage losses were about $16 million.

1994 A natural gas explosion and fire destroyed a one-story, wood frame building in Waterloo, Iowa on October 17. The force of the explosion scattered debris over a 200-foot (61 m) radius. 6 persons inside the building died, and one person sustained serious injuries. 3 persons working in an adjacent building sustained minor injuries when a wall of the building collapsed inward from the force of the explosion. The explosion also damaged nine parked cars. A person in a vehicle who had just exited the adjacent building suffered minor injuries. Additionally, two firefighters sustained minor injuries during the emergency response. Two other nearby buildings also sustained structural damage and broken windows.

1994 On November 21, a Buckeye Partners pipeline ruptured from incorrect operation in Moon Township, Pennsylvania. About 38,000 gallons of kerosene were spilled.

1994 A leak of at least 20,000 US gallons (76,000 L) of diesel fuel was discovered on a Koch Industries pipeline near Plover, Wisconsin on November 29. The leak brought this pipeline's total spill volume to 100,000 US gallons (380,000 L) on a 91 miles (146 km) pipeline section through several years.

1995

1995 Since starting operations in 1954 until 1995, Yellowstone Pipeline had 71 leaks along the Flathead Indian Reservation in Montana, spilling 3,500,000 US gallons (13,000,000 L) of petroleum products. Eventually, the Flathead refused to sign a new lease with Yellowstone.

1995 A 26-inch gas transmission pipeline ruptured and burned near Castle Rock, Washington on March 6. There were no injuries.

1995 On March 30, a Koch Industries pipeline ruptured in the parking lot of a church in Port Lavaca, Texas, spilled oil and benzine. Businesses nearby were evacuated. About 100 gallons of the mix was spilled. The failure was caused by Koch employees testing the pipeline under pressure, who thought the pipeline was full of only water.

1995 Two Native Tribes of the Flathead Nation shut down the Right of Way agreements of Yellowstone Pipeline in Montana on April 21. Past spills on Tribal lands were cited as the reason. In 1999, it was revealed that Yellowstone had 78 leaks in the previous 45 years.

1995 On December 2, 3 contractors were killed, and another injured, when a vacuum used to control flammable fumes accidentally reversed during welding at a pipeline facility near McCamey, Texas.

1996 On April 23, a Colonial Pipeline line failed near Gaffney, South Carolina, spilling gasoline. At first it was reported to be only 250 gallons spilled, but, later it was reported as 1,386 gallons. Rock abrasion was cited as the cause for the failure.

1996 On May 8, a 20-inch Columbia Gas pipeline was ruptured by a crew installing a water pipeline in Oregon, Ohio. One business nearby was evacuated.

1996 A Marathon Petroleum 20-inch pipeline ruptured at a location near Gramercy, Louisiana, on May 23, 1996. The ruptured pipeline ultimately released about 475,000 US gallons (1,800,000 L) of gasoline into a common pipeline right-of-way and marsh land. Gasoline also entered the Blind River, causing environmental damage and killing fish, wildlife, and vegetation in the area. The pipeline controller did not at first recognize the pipeline had failed, and continued to ignore alarms from the pipeline SCADA system.

1996 In May, the largest penalty in an environmental case since the 1989 Exxon Valdez oil spill, the Connecticut-based Iroquois Pipeline Operating Company will pay $22 million in criminal and civil fines for violating federal environmental and safety laws, the United States announced today. The violations stem from the construction of one of the country's longest natural gas pipelines running 370 miles from Canada through upstate New York and Connecticut to Long Island. Backfill of the pipeline was one of the issues cited. 4 individuals also received jail time.

1996 On June 17, an Olympic Pipeline products line near Everett, Washington, sprung a leak from a buckled area of pipe. About 1,000 gallons of gasoline were spilled into North Ebey Slough. The spill was discovered by a crew installing a water line nearby.

1996 A 36-inch Colonial Pipeline ruptured at the Reedy River, near Fork Shoals, South Carolina, on June 26. The ruptured pipeline released about 957,600 US gallons (3,625,000 L) of fuel oil into the Reedy River and surrounding areas. The spill polluted a 34-mile (55 km) stretch of the Reedy River, causing significant environmental damage. Floating oil extended about 23 miles (37 km) down the river. Approximately 35,000 fish were killed, along with other aquatic organisms and wildlife. The estimated cost to Colonial Pipeline for cleanup and settlement with the State of South Carolina was $20.5 million. No one was injured in the accident. The pipeline was operating at reduced pressure due to know corrosion issues, but pipeline operator confusion led to an accidental return to normal pressure in that pipeline section, causing the rupture.

1996 On August 4, 420,000 US gallons (1,600,000 L) of unspecified petroleum product spilled from a Lakehead pipe near Donaldson, Minnesota.

1996 A Koch butane pipeline ruptured, causing an explosion and fire, near Kemp, Texas, on August 24. Two teenagers were killed after driving into the unseen butane cloud while going to report the pipeline leak. A mobile home was also destroyed by the fire. The leak was caused by external corrosion. The pipeline was only 15 years old at the time.

1996 On September 26, a bulldozer operator in Grand Haven, Michigan hit & ruptured a Wolverine pipeline. Petroleum ignited, burning the bulldozer operator. About 43,000 gallons of petroleum product were lost.

1996 A leaking Amoco pipeline caused traffic to be shut down on an industrial area street in Hammond, Indiana, starting on October 17. About 1,250 barrels of gasoline were spilled. The leak was caused by external corrosion of the pipeline, installed in 1928.

1996 On October 23, in Tiger Pass, Louisiana, the crew of a Bean Horizon Corporation dredge dropped a stern spud into the bottom of the channel in preparation for dredging operations. The spud struck and ruptured a 12-inch submerged natural gas steel pipeline. The pressurized natural gas released from the pipeline enveloped the stern of the dredge and an accompanying tug, then ignited, destroying the dredge and the tug. No fatalities resulted from the accident.

1996 A Colonial Pipeline stubline in Murfreesboro, Tennessee was undergoing maintenance on November 5. The pipeline was returned to service, but a valve on that pipeline was accidentally left closed from the maintenance, causing pressure from restarting to rupture the pipeline.

1996 On November 21, an explosion occurred in a shoe store and office building in Rio Piedras, Puerto Rico. Thirty-three people were killed, and at least 69 were injured. Crews from the local gas provider, Enron, had not found any gas leaks previously, despite complaints of propane odor in the buildings.

1996 On December 11 a natural gas line operated by Williams ruptured just north of Tonganoxie Kansas. Corrosion around a fitting called a "T-Drip" failed which allowed gas to escape.

1996 on December 26, a bulldozer ruptured a 10-inch LPG pipeline near Maringouin, Louisiana, forcing the evacuation of nearby resident. There was no explosion or fire.

1997

1997 On February 6, a seal on a pump at a pump station, on a MAPCO natural gasoline pipeline, near Molville, Iowa failed, allowing the product to leak. fire then broke out, forcing all residents within a mile of station to evacuate for a time. There were no injuries. About 200 gallons of natural gasoline burned

1997 On May 30, a Colonial Pipeline spilled approximately 18,900 US gallons (72,000 L) of gasoline, some of which entered an unnamed creek and its adjoining shoreline in the Bear Creek watershed near Athens, Georgia. During the spill, a vapor cloud of gasoline formed, causing several Colonial employees to flee for safety. This spill resulted from a calculation error related to a regular procedure. No one checked the calculations, nor did Colonial have a procedure in place to check such calculations.

1997 Two different sections of a Conoco pipeline were ruptured by earth movement just a few days apart. On June 20, the pipeline ruptured near Lodge Grass, Montana, on the Crow Indian reservation, spilling 1,612 barrels of gasoline. On June 26, the same pipeline again failed from earth movement near Banner, Wyoming, spilling 704 barrels of gasoline. The Lodge Grass section of pipeline resulted in 3,400 feet of new pipeline being buried 6 to feet deep to avoid soft soil, deeper than the required 3 feet of soil coverage. There were no injuries reported.

1997 A gas pipeline was ruptured and caused an explosion and fire, in Indianapolis, Indiana, on July 21. A 20-inch steel natural gas transmission pipeline was ruptured by a contractor for the gas company, and released natural gas near an intersection adjoining the Charter Pointe subdivision. The gas ignited and burned, killing one resident and injuring another. About 75 residents required temporary shelter. Six homes were destroyed, and about 65 others sustained damage significant enough to be documented by the local investigation team. A nearby directional drilling operation had hit & weakened the pipeline before the failure.

1997 On August 11, a Chevron Corporation LPG pipeline leaked in Dayton, Texas, forcing the evacuation of 3,500 inmates from nearby correctional facilities. 5,041 barrels of LPG were lost. There were no injuries, and the failure caused was listed as "Miscellaneous".

1997 In August, residents in Vacaville, California noticed petroleum fumes, but a leaking pipeline was not found until September 10. A hairline crack from the pipe's manufacturing was the cause, and 20,000 to 60,000 US gallons (230,000 L) of petroleum products had leaked by the time the source was found.

1997 Construction equipment ruptured a Plantation Pipeline line in Fairfax, Virginia on September 9, releasing over 2,000 gallons of petroleum products.

1997 Over a period of years, more than 420,000 US gallons (1,600,000 L) of gasoline spilled from small leaks in Colonial Pipeline near Darling Creek in St. Helena Parish, Louisiana, before Colonial finally discovered the leak in December 1997. As of September 1999, a plume of gasoline, including leaded gasoline, extended over approximately 14 acres (57,000 m²) on the groundwater surface, more than 60 acres (240,000 m²) of groundwater had been contaminated, and some of the gasoline had entered Darling Creek.

1998 A rupture in Colonial Pipeline in a landfill at Sandy Springs, Georgia, discovered on March 30, resulted in the release of more than 30,000 US gallons (110,000 L) of gasoline. When the pipe was excavated, it was found to be buckled and cracked. The NTSB found that the pipeline ruptured because of settlement of soil and trash underneath the pipeline.

1998 On April 4, a tow of the M/V Anne Holly, comprising 12 loaded and 2 empty barges, which was traveling northbound on the Mississippi River through the St. Louis Harbor, struck the Missouri-side pier of the center span of the Eads Bridge. Three of these barges drifted toward the President Casino on the Admiral, a permanently moored vessel below the bridge on the Missouri side of the river. A natural gas leak resulted when the natural gas supply line to the Admiral was severed in the course of the accident. When the line broke, natural gas began escaping. Although the escaping gas did not ignite, the gas leak had continued for about 3 hours before being stopped.

1998 In South Riding, Virginia, on July 7, a natural gas explosion and fire destroyed a newly constructed residence in the South Riding community in Loudoun County, Virginia. A family consisting of a husband and wife and their two children were spending their first night in their new home at the time of the explosion.

1998 St. Cloud explosion: On December 11, while attempting to install a utility pole support anchor in a city sidewalk in St. Cloud, Minnesota, a communications network installation crew struck and ruptured an underground, 1-inch, high-pressure plastic gas service pipeline, thereby precipitating a natural gas leak. About 39 minutes later, while utility workers and emergency response personnel were taking preliminary precautions and assessing the situation, an explosion occurred. As a result of the explosion, 4 persons were fatally injured; 1 person was seriously injured; and 10 persons, including 2 firefighters and 1 police officer, received minor injuries. Six buildings were destroyed. Damage assessments estimated property losses at $399,000.

1999

1999 On January 2, a natural gas transmission pipeline exploded and burned at a pipeline facility near Pendleton, Oregon. Flames reached 500 feet high, and several town lost gas service for a time.

1999 Natural Gas Explosion and Fire at a gas pressure station, Wytheville, Virginia, destroying a home and motorcycle store. (January 3, 1999)

1999 On January 8, a leak in a 12-inch pipe at a Koch Industries tank farm in Benavides County, Texas spilled about 10,500 barrels of crude oil. The cause was internal corrosion of the pipe.

1999 In Bridgeport, Alabama, on January 22, while digging a trench behind a building, a backhoe operator damaged a 3/4-inch steel natural gas service line and a 1-inch water service line. This resulted in two leaks in the natural gas service line, which was operated at 35 psig. One leak occurred where the backhoe bucket had contacted and pulled the natural gas service line. The other was a physical separation of the gas service line at an underground joint near the meter, which was close to the building. Gas migrated into a building nearby, where it ignited. An explosion followed, destroying three buildings. Other buildings within a two-block area of the explosion sustained significant damage. Three fatalities, five serious injuries, and one minor injury resulted from this accident.

1999 On January 23, a construction crew ruptured a 10-inch diameter petroleum products pipe near Germantown, Wisconsin, spilling about 41,000 gallons of gasoline.

1999 A pipeline ruptured in Knoxville, Tennessee, and released over 53,000 US gallons (200,000 L) of diesel fuel into the Tennessee River on February 9. A brittle-like crack was found on the pipe in an area of coating failure. The NTSB expressed concern that the material's toughness had a role in this rupture. Two days before the rupture, an in-line inspection device was run through the pipe segment, with no anomalies in the rupture area reported. Contributing to the severity of the accident was Colonial Pipeline Company's failure to determine from the SCADA system that a leak had occurred, with the result that the pipeline controller started and restarted the pipeline, increasing the amount of diesel fuel that was released.

1999 On May 1, excavation equipment damaged a Koch Industries pipeline in Pleasant Hill, Iowa, spilling 3,663 barrels of crude oil.

1999 A pipeline in a Bellingham, Washington park ruptured and leaked gasoline, and later vapor from the leak exploded and burned, killing two 10-year-old boys and an 18-year-old man on June 10, 1999. Issues causing the rupture were found to be previous pipe damage by excavation, an incorrectly set up pressure relief valve, unexpected repeated remote valve closures, and new software tests on the live controlling computer.

1999 On June 24, about 100 barrels of gasoline spilled in a Buckeye Partners Terminal in Breinigsville, Pennsylvania.

1999 On August 10, an auger being used to install utility poles hit a 14-inch ethane-propane pipeline, causing an explosion & fire that killed the auger operator, and forcing evacuations near Liberty Hill, Texas.

1999 On August 29, a pump on Olympic Pipeline failed in Renton, Washington, spilling about 3,360 gallons on gasoline and aviation fuel. ABout 950 tons of soil were removed due to contamination.

1999 A Lakehead Pipeline (now Enbridge) was damaged by outside force on November 1, near Crystal Falls, Michigan. 400 people were evacuated from the area. Fire was used to burn some of the released substances, so, of about 223,000 gallons of NGL's and crude oil spilled, only about 115,000 gallons were recovered, with over 2,100 yards of contaminated soil removed in just the first 2 weeks of cleaning. The pipe broke where it was on a rock in the pipeline trench.

1999 On November 19, 2 men were injured in Salt Flat, Texas, when a leaking 8-inch propane pipeline exploded. 2 school buses had passed through the area moments before the explosion. About 6,195 barrels of propane were leaked. The pipeline failed from external corrosion.
