LOS ANGELES — California Sen. Dianne Feinstein has asked the U.S. Environmental Protection Agency to reconsider its approval of a cancer-causing chemical used by farmers in other states to kill soil-bound pests.
Feinstein said in a letter last month to the EPA that scientific evidence presented during methyl iodide's California registration shows federal regulators may have allowed the compound to be used at dangerous levels.
The EPA approved methyl iodide for use in most of the country in 2007.
California regulators opted to put the compound through their own registration process and gave it tentative approval in April, despite concerns by a scientific advisory panel that it could poison the air and water.
An EPA spokeswoman did not return a phone call.
