Work was expected to begin in early 2005 and be completed by 2006. Remediation eventually commenced in August 2005 but ceased in July 2006 due to lack of funds. During this time, the Army Corps of Engineers removed 3) of contaminated soil. On August 15, 2006 the EPA issued special notice letters to fourteen Potentially Responsible Parties (PRP). A PRP is "any individual or company potentially responsible for, or contributing to a spill or other contamination at a Superfund site." In 2009, the following parties signed a consent decree to undertake remediation at the site:  Under the terms of the decree the PRPs would be responsible for funding the remainder of the cleanup at an estimated cost of $29 million. The Town of Norton would not be held financially liable for cleanup costs, but would instead provide access to the site. Texas Instruments (TI) subsequently filed a complaint alleging that liability for the disposal of radioactive materials relating to its work for the Atomic Energy Commission was subject to indemnity by the Department of Energy. The U.S. Department of Justice then commenced a lawsuit against TI on behalf of the Corps of Engineers, which TI settled in November 2012. TI agreed to pay $15 million towards remediation of the site, without acknowledging liability. The payment went to the Corps of Engineers.
