Twelve companies have agreed to pay a total of nearly $4 million to clean up a toxic-waste dump in Monterey Park.The Environmental Protection Agency says that over time, each of the companies contributed more than 110,000 gallons of liquid waste to the site on Potrero Grande Drive. The landfill operated between 1948 and 1984.

The dump was placed on a list of the country's most potentially dangerous waste sites more than 20 years ago.
