Air/Superfund National Technical Guidance Study Series. Guideline for PredictiveBaseline Emissions Estimation for Superfund Sites, ASF-21

摘要

This report is a compendium of models (equations) for estimating air emissionsand exposure point concentrations from Superfund sites under baseline or undisturbed conditions. Exposure point concentrations can be used in the baseline risk assessment to eliminate air pathway or contaminants from further consideration (i.e., screening analyses) or can be used in support of monitoring during the exposure assessment to evaluate risk (i.e., refined analyses). The models contained in this compendium may not accurately predict emissions for all possible scenarios. Where uncertainty exists, these models and the default input variables have been designed to overpredict emissions.
