1. Introduction   1.1 Background     Site Number: 10LW    Contract Number:   D.O. Number:      Action Memo Date: 8/5/2013 Response Authority: CERCLA    Response Type: Time-Critical Response Lead: EPA    Incident Category: Removal Action NPL Status: Non NPL    Operable Unit: Mobilization Date: 11/12/2013    Start Date: 11/12/2013 Demob Date:      Completion Date:   CERCLIS ID: WAN001003091    RCRIS ID: ERNS No.:    State Notification: FPN#:    Reimbursable Account #: 1.1.1 Incident Category 1.1.2 Site Description The site is a private residence amongst agriculture lands located within the boundaries of the Yakama Reservation.  Concrete and demolition debris from a local high school was deposited on site as fill material.  Because the demolition debris came from a high school where an asbestos abatement project had occurred, there was concern that there could be some asbestos containing material (ACM) commingled with the debris. 1.1.2.1 Location The location of the site is 3690 Ashue Road, Wapato, WA. 1.1.2.2 Description of Threat There is potential that ACM could be commingled with the demolition debris.  If ACM is present, it could become friable due to weathering.  Friable asbestos poses a human health hazard. 1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results ACM was not observed during the initial site reconnaissance nor during the sampling activities.  Bulk, air, and microvac (surface dust collection) samples were collected and sent to an offsite laboratory for asbestos analysis.  The analysis of the microvac samples contained 1 to 9 asbestos fibers per sample.  The analysis of the bulk and air samples were non-detect for asbestos. 2. Current Activities   2.1 Operations Section     2.1.1 Narrative The scope of this removal action was to remove all of the debris from the Wapato High School demolition and transport the debris off site.  The PRPs used an excavator to remove the demolition debris attributable to the Wapato High School demolition project.  This debris included concrete, river rock, soil, and any other debris found commingled with the Wapato High School demolition waste.  Excavated material was placed into trucks and covered.  The trucks were decontaminated on a constructed decontamination pad. The debris was hauled to Anderson Pit landfill for deposition. 2.1.2 Response Actions to Date Monday, November 25 to Friday, December 10, 2013:  Excavation of the demolition debris from Wapato High School has been completed.  Over the duration of the project, a cumulative total of approximately 5,688 cubic yards (474 single truck loads) of demoliton debris were excavated, loaded, and transported to the Anderson Pit landfill for disposal.   Personal air samples were collected from site workers weekly.  All analytical results were less than the Permissible Exposure Limit (PEL) and workers were allowed to down grade to Level D personal protective equipment.  Ambient air samples were collected every day at three locations on the periphery of the work site: upwind, downwind, and at the fence line between the work site and the property owner's residence.  All analytical results were less than the PEL which indicates thet dust control activities adequately prevented asbestos release in dust. The truck decontamination station was de-constructed and disposed of at the Anderson Pit landfill. The retaining wall built along the Ashue Road ROW was removed. There is approximately 4,000 to 6,000 cubic yards of waste material remaining on the site.  The remaining wast material consists of tree stumps, lumber, various building materials, tires, appliance parts, household trash, rocks, and soil.  Approximately 20 various drums/containers were found.  All drums/containers were crushed, empty, and without labels.  There was no evidence of hazardous substances observed. Regulated ACM was not found in the waste pile.     2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs) This work was conducted by a group of PRPs per an Aministrative Order on Consent signed September 9, 2013.   2.1.4 Progress Metrics Waste Stream Medium Quantity Manifest # Treatment Disposal  Non-hazardous, non-regulated solid waste <1% asbestos  Concrete debris  5,688 cubic yards   Containment Landfill                           2.2 Planning Section     2.2.1 Anticipated Activities 2.2.1.1 Planned Response Activities The removal project was completed and all personnela and equipment have been demobilized. 2.2.1.2 Next Steps A removal report documenting site activities is expected in January 2014. 2.2.2 Issues  None.   2.3 Logistics Section     No information available at this time.   2.4 Finance Section     No information available at this time.   2.5 Other Command Staff     No information available at this time. 3.
