The schedule per the PPA Scope of Work (SOW), is as follows: The remedial actions will be phased to address higher priority areas first (identified above) and immediate redevelopment needs. Lower priority objectives, such as abatement or containment of non- friable hazardous building materials, removal or capping of onsite contamination determined not to be an immediate threat to human health or the environment, and areas associated with longer term redevelopment horizons, would be addressed as funding becomes available and redevelopment of the property occurs. A conceptual/flexible timeline for redevelopment of the property, including for the associated environmental investigations and remediation needed to facilitate the planned phased development will be prepared. Such timeline is anticipated to consist of: 1. Prepare an Initial Summary Report within 60 days from date of signed Consent Order. The report will summarize previous environmental investigations. It shall include at a minimum, a screening of site data against risk-based criteria, a conceptual site model (including a conceptual site hydrogeologic model), a discussion of data gaps needed to complete a site characterization in accordance OAR 340-122-0080, identification of potential interim remedial measures, source control recommendations, and conclusions. 2. Initiate evaluation and implementation of Site Stabilization BMPs within 90 days from the date of the signed Consent Order. 3. The overarching work plan will be initiated within 12 months of the signed Consent Order. 4. High priority remedial actions will be initiated within 18 months of the signed Consent Order. 5.
