In 1997, New York State and ASLF reached an agreement, the Onondaga Lake Amended Consent Judgement (ACJ), on municipal wastewater collection and treatment improvements. The ACJ called for a schedule to attain compliance with the Clean Water Act. The ACJ is a multi-year program designed to improve the water quality of Onondaga Lake while achieving full compliance with state and federal water quality regulations by December 1, 2002. ACJ projects are divided into three main categories: wastewater treatment, collection system, and lake and tributary monitoring. In January 1998, a federal judge approved the ACJ and in September 1999, the Onondaga Lake Management Conference approved and endorsed the Amended Consent Judgment (ACJ). It incorporated the ACJ into its 1993 Onondaga Lake Management Plan entitled, "A Plan of Action."
