Criteria:

Evidence exists that exposures have occurred, are occurring, or are likely to occur in the future; and the estimated exposures are to a substance or substances at concentrations in the environment that, upon short-term exposures (less than 1 year), can cause adverse health effects to any segment of the receptor population. The adverse health effect can be the result of either carcinogenic or noncarcinogenic toxicity from a chemical exposure. For a noncarcinogenic toxic effect, the exposure exceeds an acute or intermediate minimal risk level (MRL) established in the ATSDR Toxicological Profiles or other comparable value; and /or community-specific health outcome data indicate that the site has had an adverse impact on human health that requires rapid intervention; and /or physical hazards at the site pose an imminent risk of physical injury.

CATEGORY B.

Theadverse health effect can be the result ofeither carcinogenic or noncarcinogenictoxicity from a chemical exposure. For anoncarcinogenic toxic effect, theexposure exceeds a chronic MRLestablished in the ATSDRToxicological Profiles or othercomparable value; and/orcommunity-specific health outcomedata indicate that the site has had anadverse impact on human health thatrequires intervention.
