Why U.S. Oil Refineries Aren't Upgraded to Maximize Domestic Oil
In recent years, there has been growing interest and concern about why U.S. oil refineries have not been updated to fully utilize domestic oil production, leading to continued reliance on oil imports. This article explores the complex factors behind this issue and why upgrading refineries poses significant challenges.

Oil Train Derailment in El Segundo: Time, Cause, and Safety Lessons
Heavy rain likely caused the tracks to widen at a railroad curve, causing the 4 tanker cars to derail. No oil spill was reported.
This train derailed near the Chevron Refinery in El Segundo. Oil Train Derailed near businesses, retail, restaurants, and stores.
On the afternoon of January 12, 2017, at approximately 2:30 p.m., a train hauling liquefied petroleum products derailed in El Segundo, California, only blocks from the Chevron refinery. At least four tanker cars left the tracks at a sharp curve near Douglas Street and Chapman Way, their undercarriages ripped apart and scattered along the ballast. The derailment prompted swift evacuations, a large emergency response, and immediate questions about the integrity of rail infrastructure in one of Southern California’s most industrialized communities. Fortunately, no oil spill or injuries were reported, but the event serves as a sobering reminder of the risks inherent in transporting hazardous fuels by rail.
The Derailment on January 12, 2017
The derailment happened during a heavy winter rainstorm that had drenched Los Angeles County for several days. The train had just departed the Chevron refinery with multiple tank cars filled with liquefied petroleum gas. As it navigated the curve near Douglas Street, several cars slipped off the track, toppling slightly and damaging their wheels and frames. Fire Captain Evan Siefke of the El Segundo Fire Department confirmed that four cars derailed, but none were punctured. Police quickly blocked surrounding streets and ordered precautionary evacuations of businesses and homes within several hundred feet. Hazmat crews inspected the cars for leaks, while firefighters kept hoses ready in case of ignition.
The time of day mattered. The derailment occurred during mid-afternoon, when schools, offices, and nearby shops were still open, increasing the potential risk of public exposure had a leak occurred. Because the train was carrying highly flammable gases, responders feared vapor release or ignition. The order for residents to remain indoors, combined with street closures, helped minimize risk while assessments were made.
Cause: Heavy Rain and Track Instability
Investigators determined that the derailment was most likely caused by track widening due to rain-soaked ballast and subgrade instability. Several days of rainfall had saturated the soil beneath the railbed, weakening the support structure. On a curve, lateral forces from the heavy tanker cars pressed outward, forcing the rails apart. This deformation likely created enough space for wheels to slip off the tracks, dragging cars sideways and damaging their undercarriages.
Railroad officials noted that no major structural defects were initially found in the tanker cars themselves, pointing instead to weather-induced railbed failure as the primary cause. Floodwater accumulation along the tracks at the time of the derailment corroborated this conclusion. The combination of wet conditions, track curvature, and the sheer weight of fully loaded tank cars proved too much for the compromised rail alignment.
Historical Context: Oil by Rail in Southern California
Transporting petroleum by rail is not new to Southern California, but its risks have long been debated. The Los Angeles Basin is both an oil hub and a densely urbanized region. Rail lines snake through refineries, ports, and neighborhoods, carrying crude oil, gasoline, propane, and liquefied natural gas. The El Segundo derailment highlighted this juxtaposition, showing how a single infrastructure failure could put both industry and residents at risk.
Historically, oil trains have been involved in catastrophic incidents, including derailments that caused fires, explosions, and widespread evacuations. The 2013 Lac-Mégantic disaster in Quebec, Canada, in which 47 people were killed after a crude oil train exploded downtown, remains the most infamous example. Although the El Segundo event ended without fire, the potential consequences mirrored global fears of oil-by-rail accidents.
What Went Right in El Segundo
Despite the drama, several factors prevented the January 12 derailment from escalating into disaster. First, the tanker cars remained intact, avoiding leaks. Second, first responders were on site within minutes, evacuating nearby businesses and monitoring for hazardous vapors. Third, weather conditions, while causing the derailment, may also have helped prevent fire by lowering ambient ignition risk. Finally, strong coordination between the refinery, railroad, and emergency services ensured a rapid, organized response.
What Could Have Gone Wrong
The potential dangers were significant. A ruptured tank could have released a vapor cloud of liquefied petroleum gas, which, if ignited, might have caused a catastrophic fire or explosion. Such an event could have threatened not only the immediate area but also the adjacent Chevron refinery, magnifying the hazard. Contamination of stormwater systems was another concern, as residual oil products from damaged cars might have mixed with floodwaters. The lack of casualties or pollution in this case was considered a fortunate outcome.
Infrastructure Challenges Exposed
The El Segundo derailment highlighted vulnerabilities in rail infrastructure exposed to extreme weather. Curved track segments are already stress points, and saturated soil or inadequate drainage increases the risk of rail spreading. In Southern California, aging tracks and high traffic volumes add further strain. Regulators face the challenge of ensuring frequent inspections, particularly during rainy seasons, and compelling operators to strengthen railbeds against flooding.
Tank cars themselves have been another focal point of debate. Many older models lack sufficient protection against puncture in derailments. Though regulations now require upgrades with thicker shells, improved valves, and thermal protection, implementation is ongoing. Had older, weaker tankers been in use, the outcome in El Segundo could have been worse.
Lessons Learned
From this derailment, several lessons emerged. Infrastructure must be designed for resilience against extreme weather. Track drainage and ballast maintenance need reinforcement in flood-prone areas. Tank cars must be upgraded to withstand derailments without puncture. Emergency responders must maintain tight coordination with rail operators and refineries, conducting drills for worst-case scenarios. Finally, communities near refinery corridors must remain informed about the risks of oil-by-rail and know how to respond in emergencies.
Community Concerns and Environmental Justice
For El Segundo residents, the derailment was more than a freak accident—it was a reminder of the risks of living near refineries and transport corridors. The city, already known for heavy industrial activity, sits within a region where schools, businesses, and homes coexist with oil infrastructure. Community advocates point to the disproportionate burden placed on such neighborhoods, arguing that environmental justice demands stricter oversight and safer practices. Transparency, real-time communication during emergencies, and long-term infrastructure investment are among the key demands from residents.

Health Risks of Living Near Train Chemical Spills
Train derailments involving hazardous materials are not rare events, and their consequences extend far beyond immediate property damage. When tanker cars carrying toxic substances are punctured, chemicals may be released into the atmosphere, seep into the soil, or contaminate waterways. For communities situated near these derailments, the result can be both acute and chronic health problems. The effects are often influenced by the type of chemical spilled, how long exposure lasts, and whether local governments respond quickly and effectively. This article examines the short-term effects, long-term health consequences, psychological stress, and community disruption caused by train derailment chemical spills. It also explores case studies from real-world disasters and outlines preventive measures communities can adopt.
Immediate (Short-Term) Health Effects
One of the most pressing concerns after a derailment is the acute exposure of residents and first responders. People living within a few miles of a chemical release can inhale toxic gases, touch contaminated surfaces, or consume unsafe food and water. The following symptoms commonly appear in the hours or days after exposure.
Respiratory Distress
Chemicals like chlorine gas, ammonia, and vinyl chloride are potent respiratory irritants. Breathing them in can cause coughing, wheezing, chest tightness, and shortness of breath. Severe exposures may lead to chemical pneumonitis, acute lung injury, or even respiratory failure requiring hospitalization. Children, seniors, and those with asthma are at particular risk.
Skin and Eye Irritation
Direct contact with toxic liquids or aerosols often results in burns, rashes, or dermatitis. Sensitive tissues such as the eyes can be severely damaged, leading to redness, pain, tearing, or blurred vision. Long-term scarring or vision impairment is possible with high concentrations.
Gastrointestinal Problems
Spills that contaminate drinking water or food supplies pose another set of risks. Nausea, vomiting, diarrhea, and abdominal pain are frequent complaints in communities where chemicals infiltrate water systems. Some substances are hepatotoxic or nephrotoxic, stressing the liver and kidneys.
Neurological Symptoms
Certain chemicals, especially solvents and heavy metals, can disrupt the nervous system. Acute exposure may trigger headaches, dizziness, tremors, confusion, or seizures. High doses can even cause loss of consciousness.
Long-Term Health Consequences
While short-term symptoms are alarming, the most devastating outcomes often emerge over years. Chronic exposure—even at low levels—can significantly increase risks for several diseases.
Cancer Risk
Many chemicals transported by rail are known carcinogens. Benzene exposure is linked to leukemia, while vinyl chloride raises risks of liver and bladder cancer. Epidemiological studies show that residents living for decades near contaminated areas often have elevated cancer incidence compared to the general population.
Respiratory Illness
Long-term inhalation of irritants damages lung tissue. This contributes to chronic bronchitis, asthma, and COPD. Survivors of chemical disasters often report persistent breathing difficulties years after the initial exposure.
Cardiovascular Disorders
Some chemicals affect blood pressure regulation and vascular health. Over time, this increases the likelihood of hypertension, heart attacks, and strokes. These risks are compounded in populations with pre-existing conditions.
Reproductive and Developmental Effects
Toxins like phthalates, heavy metals, and solvents can interfere with human reproduction. Documented effects include reduced fertility, miscarriages, and birth defects. Children exposed in utero or early in life face developmental delays, impaired learning, and reduced motor skills.
Neurological Degeneration
Long-term exposure to neurotoxins can lead to peripheral neuropathy, Parkinson’s disease, and cognitive decline. Communities living near persistent contamination often see higher-than-average neurological illnesses over decades.
Psychological and Social Impacts
Chemical disasters also leave lasting scars on mental health. The trauma of evacuation, uncertainty about health, and loss of community stability fuel long-term psychological distress.
Anxiety and Stress
Fear of unseen contaminants can lead to chronic anxiety, insomnia, and hypervigilance. Residents often worry about the invisible nature of toxins, wondering if their homes, yards, or drinking water are safe.
Depression and PTSD
Prolonged displacement, property loss, and health concerns often trigger depression and post-traumatic stress disorder. Survivors may replay the event mentally or avoid areas associated with the disaster.
Community Breakdown
Entire towns can suffer from stigma, declining property values, and weakened social cohesion. Families may relocate, businesses may shutter, and tax bases may erode. These disruptions make recovery difficult, compounding the physical and mental toll.
Preventive Measures and Safety Strategies
Reducing health risks requires strong prevention, rapid response, and long-term support.
Regulatory Oversight
Governments can limit risks by enforcing stricter rules on transporting hazardous materials. This includes regular inspection of railcars, safer tank designs, and designated routes that avoid residential areas.
Emergency Preparedness
Clear evacuation plans, community drills, and rapid mobilization of hazmat teams are essential. Local hospitals should be equipped to handle chemical injuries, and first responders should be trained in hazardous material protocols.
Public Communication
Residents need accurate, timely information. This includes emergency alerts, safety hotlines, and educational campaigns to help people recognize symptoms and know when to evacuate.
Long-Term Medical Monitoring
Ongoing screening for respiratory illness, cancer, and neurological conditions is crucial. Communities affected by past spills benefit when governments fund health clinics, epidemiological studies, and specialist access.
