Sample results will require assessment for the purpose of developing background levels. These results and their interpretation will have to be transmitted to residents and building owners who participated in the study.

Prepare a final report which summarizes the study and presents the rationale used to establish background levels for the various potential contaminants of potential concern.

Expected Completion Date:

Given the voluntary nature of the Background Study it took longer than originally projected to obtain access to the number of buildings we identified. This will also result in a delay in the completion of this study, the lAG completion date will still require an extension. EPA assumed the access responsibilities from the NYCDOH. This change resulted in an increase in EPA personnel costs. The change in projected completion date and cost changes are reflected in an lAG amendment which is presently circulating.

The revised project completion date has been estimated to be April 30, 2003.

Complex Issues Encountered: None to date.
