State tightens restrictions on cancer-causing pesticide Telone


The California Department of Pesticide Regulation (DPR) will enact new regulations on the cancer-causing pesticide 1,3-Dichloropropene—known by its brand name, Telone—starting Jan. 1, 2017.

Telone is a fumigant pesticide used against insects, nematodes, and organisms that exist in the soil and threaten crops. In California, it’s used most often on the Central Coast and in the San Joaquin Valley. In the first half of 2016 alone, growers applied more than 5,300 gallons—or about 53,000 pounds, because the Environmental Protection Agency estimates a gallon of Telone weighs about 10.1 pounds—of the fumigant to crops in Santa Barbara County.

The new restrictions will limit Telone application to 136,000 pounds within each “township,” or 6-mile by 6-mile area of land, per year. Currently, those limits range between 90,250 and 180,500 pounds per year, and unused allocations can “roll over” from one year to the next—a loophole that will close under the DPR’s new regulations.

An observational study conducted by the DPR from 2010 to 2014 found that in Santa Maria, the risk of cancer from exposure to Telone is, on average, one person per every 120,000 people—which didn’t exceed the agency’s goal cancer risk.

However, the DPR conducted a risk assessment of the chemical to see whether human health (in both adults and children) was sufficiently protected in a range of situations. The assessment found several scenarios in which people exposed to Telone face a significant health risk.

In a news release from the DPR, agency Director Brian Leahy said the new rules should better protect people who are exposed to Telone, while still allowing for its use as an effective pesticide.

“While our studies continue to show that we have been protective of human health, I believe that overhauling the way we manage the pesticide, to be based upon a fixed annual amount, will be health-protective and simpler to manage,” Leahy said in the release.

What'd you make of the county's decision to close beaches for the Fourth of July weekend?

It was sensible since counties to the south closed their beaches.
I was OK with it. I set off fireworks at home instead.
It was ridiculous. The restrictions have to stop.
It didn't matter. I went to SLO County.
