The Environmental Protection Agency has told Central Chemical Corp. to erect a 10-foot-high fence 20 feet beyond the existing fence at the rear of its property in the 700 block of Mitchell Avenue in Hagerstown.
The pesticides DDT and chlordane were found in soil samples taken outside the existing fence, said Hal Yates of EPA Region III. The order was issued under the Superfund Emergency Response Program, he said.
"Under this program, we can come in when something is deemed an imminent and substantial threat to the public health," Yates said. "In this case, we want to prevent direct contact with the soil by large animals and humans."
Hagerstown zoning only allows for a 6-foot high fence. Central Chemical asked the city to make an exception in the case.
