The performance standards established in the consent decree for each site incorporate CWA requirements to the extent that site remediation must achieve the elimination of unpermitted discharges and ensure compliance with applicable permit effluent limits

Section IX establishes the site-specific cleanup levels and operational benchmarks that TMC must achieve at each of the four sites

Section X defines the factual and technical conditions that must be satisfied before a site may be deemed "complete" for purposes of initiating the termination process

Termination is available only on a site-by-site basis and requires: (i) a formal Certification of Completion submitted by TMC; (ii) independent review and concurrence by the court-appointed monitor; (iii) written approval by EPA; (iv) expiration of a five-year post-completion period during which TMC must continue all monitoring and operation-and-maintenance activities; and (v) a petition to the Court for termination

TMC must design, construct, and operate a continuous AMD treatment system capable of achieving greater than 99% copper removal efficiency on a sustained basis

The treatment system must be sized to handle the full range of AMD flow rates experienced at the site, including peak flows during spring snowmelt
