In an effort to limit any lingering health hazards, the Montrose Chemical Corp. has begun to grade and will pave its former DDT manufacturing plant in the Los Angeles city strip area.
The U.S. Environmental Protection Agency and the South Coast Air Quality Management District will oversee the grading and installation of a 2- to 3-inch asphalt cover over the entire 13-acre site on Normandie Avenue near Del Amo Boulevard.
EPA officials said plans for the six-week project--which is not regarded as a final cleanup--provide for controlling dust during grading and monitoring the air for any DDT released.
Montrose officials said they are placing the asphalt cover to further comply with an order issued by the EPA in 1983. Montrose was ordered to prevent the discharge of the now-banned pesticide, a suspected carcinogen, after traces of it were found in the waters of Los Angeles Harbor and traced back to Montrose. The chemical company built a six-inch shoulder to prevent contaminated rainwater from running off the property.
