2019-26974. Notice of Lodging of Proposed Consent Decree Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980

On November 25, 2019, the Department of Justice lodged a proposed Consent Decree with the United States District Court for the District of Colorado in the lawsuit entitled United States of America v. Pioneer Natural Resources Company and Pioneer Natural Resources USA, Inc., Civil Action No. 1: 17-CV-00168-WJM-NYM.

In January 2017, the United States, on behalf of the United States Environmental Protection Agency (“EPA”) filed a complaint against Pioneer Natural Resources Company and Pioneer Natural Resources USA, Inc. (“Settling Defendants”) seeking reimbursement of response costs incurred under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), 42 U.S.C. 9607(a), for response actions at or in connection with the release or threatened release of hazardous substances at Operable Unit 1 (“OU1”) of the Nelson Tunnel/Commodore Waste Rock Pile Superfund Site (“Site”). The United States also sought a declaration of Settling Defendants' liability, pursuant to Section 113(g) of CERCLA for all future response costs to be incurred by the United States in connection with the OU1 Site.

In September 2017, Pioneer filed a counterclaim against the United States alleging that the United States is liable under Sections 107 and 113 of CERCLA, 42 U.S.C. 9607 and 9613, as both an owner of OU1 at the time that hazardous substances were disposed of at OU1 and a current owner of OU1. Settling Defendants in their counterclaims sought a judgment against the United States for the United States' equitable share of costs incurred and that may, in the future, be incurred as a result of the release or threatened release of hazardous substances at the OU1 Site.

The proposed Consent Decree requires Settling Defendants to pay $5,775,000 for past and future response costs incurred by the United States in connection with the Site. The proposed Consent Decree also requires Settling Federal Agencies, the United States, on behalf of the United States Department of Interior and the United States Department of Agriculture, on behalf of the United States Forest Service (“USFS”), to pay EPA $425,000 for past and future response costs incurred in connection with OU1 at the Site. Future response costs associated with the OU2 remedial action will be resolved through a memorandum of understanding or interagency agreement between the USFS and EPA. The proposed consent decree will resolve all CERCLA claims alleged in this action by the United States against Settling Defendants and any potential liability within the meaning of Sections 107 and 113 of CERCLA, 42 U.S.C. 9607 9613(f)(2), for Settling Federal Agencies.
