For Immediate Release: No. 20-OPA005

DEPUE, Illinois (FEBRUARY 18, 2020) – U.S. Environmental Protection Agency

recently issued a unilateral administrative order to two potentially responsible parties

(PRPs) to clean up contaminated soil in a portion of the New Jersey Zinc/Mobil

Chemical Corp. Site in the Village of DePue. EPA estimates the cleanup cost will cost

TCI Pacific Communications and CBS/Westinghouse of PA, Inc. about $10 million.

The order requires the PRPs to design a remedy and devise a cleanup plan for soil in

residential areas, public property, parks, alleys, a school, and other miscellaneous

properties known as Operable Unit 4 (OU4).

The OU4 cleanup must satisfy all the requirements outlined in the Illinois EPA’s June

2017 Record of Decision. EPA plans to hold a public meeting in the community to

discuss soil sampling and cleanup and to answer questions before work begins this

spring.

Background

The DePue/New Jersey Zinc/Mobil Chemical Superfund site is a 950-acre area that

once housed a zinc smelter and a phosphate fertilizer plant. The site is contaminated

with elevated levels of metals that include zinc, lead, arsenic, cadmium, chromium,

copper, and manganese.

In October 2019 at the request of Illinois EPA, the federal agency assumed the lead for

the cleanup because the state’s negotiations with PRPs had reached an impasse.

Under federal Superfund law, EPA has additional authorities to help leverage

completion of the cleanup.
