Triumph Mine Tailings Piles Withdrawal of Site from Proposal to the NPL - April 30, 2003 EPA does not believe that further response under Superfund is appropriate at this time. All major sources of risk have been mitigated. All contaminated yards, gardens, roads, waste rock, tailings, and other soil areas have either been excavated and replaced with clean soil, or capped with clean soil and a vegetative cover. The State has indicated that it will enforce the consent order requiring ASARCO to address mine water discharge from the mine portal, and if those efforts fail, seek alternative sources to do the work. The State and community strongly support withdrawing the site from the proposed NPL, and EPA does not believe the mine water discharge warrants retaining the proposal to list the site on the NPL.
