The Environmental Protection Agency (EPA) will implement a project under the Project XLC program for certain facilities in Steele County, Minnesota. The terms of the project are defined in a Final Project Agreement (FPA) which was made available for public review and comment through a Federal Register notice on December 29, 1999 (64 FR 73047) and signed on May 31, 2000. In addition, EPA is promulgating a site-specific rule, applicable only to the Steele County Sponsors who are Participating Industrial Users, to facilitate implementation of the project. This site-specific rule provides regulatory changes under the Clean Water Act (CWA or the Act) to implement the Community XL project, which will result in superior environmental performance. The site- specific rule changes some of the requirements which apply to the Sponsors who are Participating Industrial Users to promote a reduction in the discharge of four priority metals, a reduction in water usage, and the development of an Environmental Management System. An incentive-based monitoring approach will be implemented, such that as discharge reduction goals are met, monitoring frequency may be reduced, mass-based limits will replace certain concentration limits, and an alternative Significant Noncompliance (SNC) publication approach will be tested. Monitoring reductions for pollutants determined not to be present in an industry's wastestream will also be authorized.
