On the early morning of May 9, Christine Mills awoke to a piercing alarm coming from the Metrolink Central Upkeep Facility.
As Mills ran towards the sound, still dressed in her pajamas, she noticed a white cloud billowing from two practice yard towers. The towers maintain sand used to assist locomotive wheels grip metal tracks.
The cloud, which she recorded on video, was one thing she had by no means earlier than witnessed throughout the seven years she’s lived in Elysian Valley, a northeast Los Angeles group located alongside the Los Angeles River.
“There was dust over the LA River and dust was blowing toward Cypress Park, hundreds of feet from where people live,” Mills stated. “I am used to seeing black clouds any time they start up their locomotives. But this time I saw a white cloud of dust, 1,000 to 1,500 feet in the air.”
Mills added that the cloud, which she stated remained seen for about 90 minutes, “made me anxious.”
She researched mud clouds as byproducts of sand used in development and manufacturing and discovered that silicon, a standard element of sand, turns into silica mud when launched into the air.
After speaking to others in the sand enterprise and locomotive business, she turned nervous that the cloud may need contained silica. Additionally referred to as silicon dioxide, silica is a recognized human carcinogen.

Greater than six months later, Mills and her group, the Los Angeles River Communities for Environmental Fairness — a gaggle with about 20 members, most from the neighborhood — are still trying to regulatory businesses to study extra about what was in the cloud.
The businesses don’t have any clear solutions. They observe there are no check samples of the cloud to assist decide what was in the air, and missing that they will’t supply agency conclusions. It’s even troublesome to hyperlink comparable incidents to precise well being issues.
However the lack of solutions about the cloud and its contents is illustrative of the uncertainty that this group — and many others in the neighborhood of comparable amenities in Southern California — should reside with day by day.
Metrolink’s Central Upkeep Facility in Taylor Yard is situated alongside the Los Angeles River a few mile from houses and faculties in the communities of Elysian Valley and Cypress Park.
Up to now, the South Coast Air High quality Administration District has issued two separate Notices of Violation relating to Metrolink’s sand towers and the May 9 cloud. Each violations, issued July 18 and Aug. 25, are listed in the company’s on-line Facility INformation Element (FIND) web site.
Metrolink confirmed that it acquired violation notices linked to a sand supply into twin silos at its Central Upkeep Facility, the place Mills noticed the white cloud.
In its discover of violation dated July 18, SCAQMD cites the Southern California Regional Rail Authority — Metrolink’s father or mother company — for “failure to maintain equipment in good operating condition at all times.”
The second discover, dated Aug. 25, states: “The equipment (silos) unit shall not be operated contrary to the conditions specified in the permit to operate.”
The standing of each violations was listed as “pending” on Nov. 23. The company has but to launch full inspection studies, and didn’t give a launch date, saying the incidents are “still under investigation internally,” in line with Sam Atwood, SCAQMD media relations supervisor.
However in a memo to board members written by SCAQMD Government Officer Wayne Nastri, the company elaborated on issues occurring at the Metrolink upkeep yard.
“Previously, an inspection had been conducted at this facility and an NOV was issued,” Nastri wrote. “Employees mentioned the nature of the drawback and had been advised that the facility had reportedly addressed and corrected the drawback, by reinstalling correct filter media in a vent in the east silo.
“Staff revisited the facility and found dust emanating from a vent in the west silo and therefore issued a second NOV.”
Each NOV may result in civil and/or felony penalties, and fines can value as much as $1 million per day for companies, in line with the SCAQMD.
The violations have been handed to the SCAQMD’s authorized workplace for potential settlement, Atwood stated, including that in this case there’s inadequate proof to help felony prosecution.
“There is no set timetable for reaching a settlement,” he wrote.
The SCAQMD didn’t seize any samples of the mud cloud and subsequently, couldn’t analyze the mud or check it for silica, Atwood stated.
Silica is a listed poisonous air contaminant and amenities that emit silica are required to report it to regulators.
However the Metrolink upkeep yard is exempt from the reporting requirement of the AB2588 Air Toxics Scorching Spots program, Atwood stated, as a result of it “does not meet the minimum requirements.”
Atwood stated he was unaware whether or not the four-county anti-smog company had ever documented any instances of a launch of silica mud into the air.
In 2007, SCAQMD carried out air monitoring for crystalline silica at an elementary faculty in Duarte after residents grew involved about mud from close by sand-and-gravel quarry operations, he reported.
Outcomes have been damaging.
Rey Dominguez lived in Elysian Valley from the age of 9 to his dying at age 67.
The avid bike owner died of pulmonary fibrosis in September 2012, stated his widow, Cecilia Dominguez. The illness’s commonest trigger is silica mud, based on the Nationwide Institute of Well being.
A well being danger evaluation carried out by Metrolink in 2014 didn’t absolutely think about respiratory illnesses from silica, Mills stated, however as an alternative targeted on most cancers dangers from idling locomotives giving off diesel fumes.
Dominguez doesn’t know if emissions of silica or diesel exhaust made her husband sick.
“All I can say is it aggravated his condition,” she stated.
With out commenting on Domiguez or the incident at the Taylor Yard, Dr. Raj Dasgupta, a pulmonary specialist and professor at USC’s Keck Faculty of Drugs, stated individuals dwelling close to or working with processes that produce sand mud must be involved about silica publicity.
Dasgupta additionally stated it is probably going that the sand delivered to assist with locomotive traction incorporates silicon, generally discovered in rock, which may be launched as silica mud or crystalline silica. Persistent publicity can scar lung tissues and trigger non-cancer lung illnesses that outcomes in shortness of breath and ultimately, untimely demise, based on the federal Occupational Security and Well being Administration.
Publicity to silica mud may cause silicosis, a debilitating lung illness, he stated. Those that have silicosis have a better incidence of contracting tuberculosis, he added.
“Silicosis is also associated with the production of antibodies that puts a person at risk with rheumatoid arthritis,” Dasgupta stated. “If you inhale (silica), it goes into the lungs…and can diffuse into the blood stream.”
In 2013, 46,000 deaths globally have been on account of silica publicity, he stated.
As many as 2.three million American staff are uncovered to silica annually, in response to OSHA. Most instances of silicosis in the United States contain individuals who have been uncovered for a number of years on the job, the company reported.
Silicosis deaths quantity about 100 per yr, in accordance a 2015 OSHA research.
Metrolink response to the cloud
Metrolink, in a tweet posted Oct. 15, denied the mud cloud uncovered the communities to a violation of silica mud requirements.
“At no time has Metrolink been cited for polluting the community with silica,” the company tweeted.
The response got here 12 days after Mills and the LA River Communities for Environmental Fairness tweeted about the video, alleging that Metrolink was “polluting our communities with cancerous respirable silica.”
At no time has Metrolink been cited for polluting the group with silica. Please contact Group Relations (email@example.com) to make clear this misunderstanding. ^BH

“What was occurring during that photo and video was a delivery of sand,” Scott Johnson, Metrolink spokesman, stated. “And the AQMD inspector came out and observed the tower and observed the violations that resulted in the notices.”
Johnson wouldn’t say whether or not the sand supply produced silica mud.
“The community member references it as silica,” he stated. “Silica is a compound found in sand, dirt and rocks.”
In an e-mail despatched to Mills and others in the group, Metrolink’s Sylvia Novoa requested LARCEE “for a correction” to the Oct. three tweet, saying Metrolink’s practice yard is in compliance with employee publicity requirements for silica set by OSHA.
“The towers have operated filters to prevent/reduce atmospheric contamination and have had these filters in place since 1991,” the e mail concluded.
Usually, Atwood stated, “respirable crystalline silica” in the ambient air just isn’t a well being drawback in the brief time period, however might be after continual long-term publicity.
Past the mud cloud
Mills and her neighbors say they reside subsequent to a river being cleaned up however really feel that, sarcastically, the practice yard tarnishes the inexperienced effort.
Neighbors Xochitl Ivanov, 36, her husband Boris and their two youngsters, each underneath 5 years previous, have taken extraordinary steps to restrict publicity to air pollution. The Ivanovs have put in particle filters on their heating and air con techniques.
“When you change the filter, it looks like it came from a vacuum cleaner: black and full of dust bunnies,” she stated.
They’ve even painted their home windows shut to maintain out advantageous particulates and they restrict outside publicity, she stated.
“We are kind of prisoners in our own four walls,” Ivanov stated.
Finally, Mills and Dominguez need Metrolink to maneuver the practice yard, which they assume operates too near residential areas.
“You feel totally helpless,” Mills stated. Still, she intends to convey the matter of the mud cloud to native representatives in Congress and Sacramento and the metropolis of Los Angeles.
On the topic of in search of additional info, Dominguez added: “I tell people, don’t wait until it knocks on your door.”
