LOS ANGELES - The U.S. Environmental Protection Agency is examining a report that warned an agricultural pesticide approved by the agency could poison the air and water.
The EPA wrote in a letter last week to Sen. Dianne Feinstein that it was reviewing the report from a panel of California scientists.
The agency is also reviewing a plan by California regulators to mitigate environmental and health risks from the chemical methyl iodide.
The letter was in response to Feinstein's request that the EPA reconsider its approval of the compound, which the agency sanctioned 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.
