On August 10, 2017, HSCD Division Director Karen Melvin signed an Administrative Settlement Agreement and Order on Consent for Removal Action (Removal Consent Order) with Olin Corporation for a time-critical removal action at a portion of the Saltville Waste Disposal Ponds Superfund Site (Site) in Washington and Smyth Counties, Saltville, Virginia. The removal action will be conducted along approximately one and one-half miles of the right descending bank of the North Fork of the Holston River (NFHR), from about River Mile (RM) 80.9 to RM 82.35 (Riverbank Area). The Riverbank Area includes areas where high pH water having a pH equal to or greater than 11.5 standard units (s.u.) is seeping from the waste disposal Ponds 5 and 6 portion of the Site into the NFHR. The most significant human health risks at the Site are associated with serious eye damage from exposure to the high pH water. In addition, the high pH water is potentially toxic for various aquatic biota. The selected removal action will include: (1) placing riprap at and near four areas identified by EPA in the Riverbank Area where water with a pH equal to or greater than 11.5 s.u. discharges into the NFHR to create a physical barrier to the seeps, collect and direct the seeped material into mixing areas to lower the pH toward neutral, and allow for mixing of the seeped material with river water prior to potential direct human exposure; (2) posting No Trespassing signs along the entire reach of the Riverbank Area an
