Progress of AOC II

What will be done under AOC II, and where are we now?

The steps for implementing AOC II are:

Site Management Strategy – the purpose of the Site Management Strategy document is to review available historical and public information about the area that will be investigated; develop a preliminary conceptual model of the area, which defines the conditions of the area to be investigated; identify additional items that may need to be researched or reviewed to provide more detail to the conceptual model; and outline a management strategy or approach to be used to conduct the investigation. This document has been approved by the USEPA, and is available for viewing on its website: www.epa.gov/region5/sites/pines

Remedial Investigation/Feasibility Study (RI/FS) Work Plan including the Field Sampling Plan – this document outlines the types of investigations to be conducted, where and what kinds of samples will be collected, how the samples will be analyzed, and how the data will be evaluated. This document has been approved by the USEPA, and is available for viewing on its website: www.epa.gov/region5/sites/pines

Remedial Investigation – this is the phase of the investigation when samples are collected and analyzed. This portion of the investigation was completed on January 17, 2008. Although not required by the AOC II, regular measurements of water levels and samples for the analysis of boron continue to be collected in the Area of Investigation.

RI Report – this report summarizes the data collected during the remedial investigation. The report was submitted to the USEPA on May 19, 2008, and was conditionally approved on November 3, 2009. The final report was provided to the USEPA on March 5, 2010. This document has been approved by the USEPA, and is available for viewing on its website: www.epa.gov/region5/sites/pines.
