Switch In Toxic Cleanup Priorities Risks Leaving Homes Contaminated With Lead
This article is published in its full length at CALmatters.org
Struggling with what officials call the largest and most expensive toxic contamination in California history, embattled state regulators have changed the formula for assessing the level of lead-laced soil in residential areas—a move that could result in a significant number of homes falling off the priority cleanup list.
The little-noticed switch has confused residents living around the now-shuttered Exide Technologies battery recycling plant in southeast Los Angeles, and raised suspicions that those with high levels of lead could be bumped so far down the cleanup list that the state will run out of cleanup money before it helps them.
Two lawmakers who represent the predominantly Latino working class neighborhoods promised action after CALmatters questioned them about it.
“I was not aware of this change in process … but will conduct my due diligence to understand the factors now being considered,” Assemblywoman Cristina Garcia (D-Bell Gardens) said in a statement. “We know the lead leaked by Exide is harmful to the community; this is not debatable.”
Senate President Pro Tem Kevin de León said the state Department of Toxic Substances Control in charge of the cleanup is already in “deep distress,” citing a recent annual report that “shows numerous deficiencies.” He also said he hadn’t been informed of the formula change, telling CALmatters: “There needs to be more transparency how they make these changes, why they are making this change, when did they make this change and will these changes have an adverse impact on the communities that surround the Exide facility.”
One year ago the state—using a formula that made a home eligible for priority cleanup if any one of its several soil samples showed a hot spot of contamination—had identified 208 homes for priority cleanup (and cleaned some of them). But then in July it jettisoned that approach and substituted a federal formula, calculated primarily by averaging all the soil samples from a property. As a result, even though twice as many homes had then been tested, the rule change shrunk the priority list to 52 properties.
Testing has continued ever since, with the department saying it has sampled more than 6,700 properties to determine which have enough lead contamination to qualify for cleanup, and which of those have concentrations high enough to earn them a place on the priority list.
But how many properties are eligible for the priority list is a mystery—department spokesman Jorge Moreno said the most recent number he could provide was from last summer.
The state toxics department allowed the Exide battery plant to operate for 33 years under a temporary permit, despite documenting dozens of environmental violations at the 15-acre site. During its operation, the plant spewed chemicals into the air, including lead, which settled into local yards, playgrounds and gardens.
Nobody knows for certain what the price tag for comprehensive cleanup will be. Thus far the average cost per property is $2,000 to test and $42,000 to clean. Given the expectation that many of the more than 10,000 properties being tested will qualify for remediation, and factoring in administrative costs, Los Angeles County Supervisor Hilda Solis and others have said cleanup costs could rise above $400 million—an estimate the state toxics department hasn’t disputed.
But the state has allocated nowhere near that amount. Last year—two years after Exide first reported finding lead in the soil of homes near the plant—Gov. Jerry Brown and the Legislature committed $176 million to clean up 2,500 of the most contaminated parcels within a 1.7 mile radius of the plant.
In the months since, the state toxics department has been working on the required draft plan and environmental impact review. Department officials said the stalled cleanup could resume as early as this summer. Full cleanup, assuming the funds are found to do it, could take many years.
Meanwhile thousands of families continue to live with lead-contaminated soil around their homes, trying their best to keep their kids and grandkids away from it while they wait.
Asked why the change was necessary, state toxics department director Barbara Lee said “We changed the approach to use the U.S. EPA’s approach, the approach that is used pretty much across the nation, because of the number of properties we have to prioritize. We will start with those that have the greatest potential exposure to vulnerable populations and work our way down and we will do as many as we can do.”
She insisted the change has “nothing to do with the expense.”
Tamara Zielinski, the department’s branch chief overseeing the Exide residential cleanup, said it was the new ranking account for “a likelihood of people coming in contact with it, the type of property it is and several other factors”—with special consideration given to homes with small children and pregnant women.
But other experts challenged the rationale.
“It’s clear this is a large problem, and if one set of rules tells them a certain number of homes to clean up and another set of rules says a smaller number, frankly, the right thing to do is to do the big one,” said Peter Green, a researcher at the University of California, Davis department of civil and environmental engineering who specializes in lead contamination. “I understand it’s costly, but trying to drag it out and trying to do it a little cheaper I bet will cost more in the long run with lawsuits….These are people’s homes, they have children, exposure. You can’t trim it back, you have to do it right.”
David Bellinger, a neurology professor at Harvard Medical School who studies lead exposure, said if forced to choose a property that has one spike score and another property with more consistent levels, he would prioritize the one with the spike “because that would increase my index of suspicion because there are other high spots.”
The federal Centers for Disease Control says there is no safe level of lead, a neurotoxin responsible for developmental disabilities and cognitive deficiencies.
One of the tested homes belongs to World War II veteran Fermin Vega, who is 93. He has lived in the house, or the one next door, for more than 60 years. His soil results show that one part of his yard has a high point of 841 parts per million. But under the new formula’s average-based calculation, his score is only 492 ppm.
“It’s not right. They should prioritize wherever it’s high, period, no matter,” said his son Joseph Vega. “Like for my father, he’s elderly and he’s more susceptible, he’s like a young child so that shouldn’t matter.”
“They’re rigging the game now,” he added.
The state standard for cleanup of lead in residential areas is 80 parts per million. The original cleanup plan for the Exide area tagged any property with at least one sample above 80 ppm. Properties with at least one sample above 1,000 ppm were placed in the first priority group for cleanup.
The new formula averages all the samples taken from various spots around a property, adding some additional points for areas with higher sample results. But some homes with elevated levels near the bottom of the spectrum—close to the state’s limit of 80 ppm—could be left off the cleanup list entirely once their slate of samples is averaged out under the new formula.
Zielinski, the toxics department’s branch chief, said she did not believe that any properties would be left entirely off the cleanup list—although without more funding, being on the list may not be a guarantee of getting cleaned up. But in response to further CALmatters questioning, Moreno, the department’s spokesman, acknowledged a property could have a sample above 80 ppm and no longer be slated for cleanup.
“They are not cleaning up every home that is above 80 (ppm),” said Jill Johnston, assistant professor of preventative medicine at the University of Southern California and a member of the state-created Community Advisory Group on the Exide cleanup. “It puts an already impacted community at risk to do partial cleanup that leaves their kids and future generations at risk of lead exposure.”
Johnston also finds fault with the agency’s draft plan to clean up only areas considered contaminated—for example, only the right side yard but not the left or back or front.
“They should clean up the whole yard,” she said. “It’s not worth leaving hot spots behind that you didn’t test.”
Plenty of people remain unsatisfied with the new risk calculation, said Mark Lopez, head of East Yard Communities for Environmental Justice and a member of the Community Advisory Board. “We would like for the highest score to be the standard,” Lopez said. “So if I’m testing one sample over a 1,000, that should place me in priority 1. It should not be averaged out with a bunch of my other samples….Because that acute threat of exposure should be enough to put me there.”
Several years ago, the Legislature created an Independent Review Panel to oversee how theagency operates. Its most recent annual report, de León said, “shows numerous deficiencieswith operations, communications, accountability and transparency.” Pending bills aim to further reform its operations.
