Book Description

This study is to screen and evaluate remediation alternatives for IRP sites at Alpena CR TC, Alpena, MI. The purpose of this FS is to develop, screen, and evaluate remedial alternatives which are potentially capable of meeting the remedial action objectives (RAOs) identified for the sites at the Alpena CRTC. The first step in the PS process is to identify the RAOs and general response actions (GRAs). RAOs consist of medium-specific or site-specific goals for protecting human health and the environment. GRAs are actions that satisfy the remedial action goals. After the identification of the RAOs and the GRAs, the next step in the FS process is to identify and screen technologies. In this step, the universe of potentially applicable technology types and process options are reduced by evaluating the options with respect to technical implementability. The retained technologies are then combined to form remedial alternatives capable of meeting the RAOs applicable to a particular site. These remedial alternatives are screened based on effectiveness, implementability, and cost. The purpose of this screening is to reduce the number of alternatives that must undergo a more thorough and extensive evaluation during the detailed analysis step.
