## Summary

On January 24, 2022, EPA executed the second modification (Modification 2) to the June 5, 2002, Administrative Order on Consent (AOC) for Removal, Docket Number III-2001-0007-DC, entered into by the City of Philadelphia and EPA pursuant to CERCLA Sections 106(a) and 122(a), in connection with Enterprise Avenue Landfill/Philadelphia International Airport Runway 8-26 Site Area Project (Site) located in southwest Philadelphia.  Modification 2 directs the City to (1) decommission the pump and treat system at the site, which after 11 years of operation was no longer effective to reduce volatile organic compounds and metals in groundwater; (2) properly plug and abandon the groundwater extraction wells; and (3) conduct long-term groundwater monitoring to confirm that contaminant concentrations do not migrate from the Site.  Although contaminant concentrations and location have been stable for a decade or more, the AOC, as modified, also requires remedial actions to be performed by the City if groundwater monitoring indicates that contaminate concentrations are increasing or that contamination is migrating from the Site.
