Common use of DEFINITION OF EXPOSURE SCENARIOS TO 8E EVALUATED Clause in Contracts

DEFINITION OF EXPOSURE SCENARIOS TO 8E EVALUATED. This risk assessment addresses the potential health hazards associated with the following alternatives: 1) no action; 2) development of the previously approved, all commercial plan; and 3) development of the currently proposed plan which includes both residential and commercial facilities. The assessment considers both the development and occupancy phases of the planned developments. The individuals most likely to have the highest long-term health risk resulting from any airborne chemical releases from the site will be the site occupants. A number of concerns have also been expressed relative to potential short-term effects on health associated with construction activities at the site. The health impacts (particularly carcinogenic response) associated with exposure to the relatively small quantities of volatile organic chemicals found in the landfill gas are principally associated with long-term exposure. However, this assessment addresses some of the potential short-term exposure concerns for construction workers. There are a large number of potential exposure scenarios that could be evaluated for any project. The following scenarios have been selected as representative of the range of potential exposures that might be associated with this project and for which it would be appropriate to characterize health risks. These exposure scenarios are intended to fairly broadly bound the range of potential exposures that might occur as the result of a variety of potential site development activities. Exposure scenarios are described for both the no-action alternative and the construction and occupancy phases of the project for each of the populations of interest.
