On December 28, 2010, EPA issued a NOD pursuant its policy, ÂIncentives for Self-Policing: Discovery, Disclosure, Correction and Prevention of Violations, 60 FR 66706 (April 11, 2000) (the AAudit Policy@) and ÂSelf Audit/Self Disclosure Agreement between the Maryland State Highway Administration (ÂMSHAÂ) and the U.S. Environmental Protection Agency Region III (September 15, 2008). The NOD is based on a self-disclosure provided by the MSHA regarding its Denton Maintenance Facility, located on 508 Caroline Street, Denton, MD 21629. In a letter to EPA, dated September 23, 2009, the MSHA disclosed potential violations of the Resource Conservation and Recovery Act and the Clean Water Act, which occurred at its Denton Facility. EPA evaluated the disclosure and resolved the matter by issuing a NOD.
