APPENDIX B:

EXPLANATION OF COMPARISON VALUES
Background Levels reported to exist in an uncontaminated environment.
Child A subscript child adjacent to the EMEG or RMEG indicate that the comparison value was determined using a child exposure scenario. Child EMEGs and RMEGs are lower for children.
EMEG Environmental Media Evaluation Guides are based on ATSDR's minimal risk levels (MRLs). An MRL is an estimate of a daily human exposure to a chemical that is likely to be without an appreciable risk for noncarcinogenic effects over a specified duration of exposure (acute, intermediate, chronic).
CREG The Cancer Risk Evaluation Guide is an estimated contaminant concentration that would result in no more than one excess cancer in a million (10E-6) persons exposed over a lifetime. CREGs are calculated from EPA's cancer slope factors (CSFs).
LTHA The Lifetime Health Advisory represents a contaminant concentration that EPA considers to be protective of noncarcinogenic health effects during a lifetime (70 years) of exposure.
MCL The maximum permissible level of a contaminant in a public water system.
RMEG Similar to the EMEG but derived from EPA's reference dose. It is the concentration in a specific media at which daily human exposure is unlikely to result in adverse noncancerous effects.

These were observed flowing from a containment area surrounding the former tank farm. The discharge was flowing through a narrow channel which had been cut in the northeast corner of the east levee of the containment area. The discharge continued for a distance of approximately 50 feet then into the Sabine Neches Canal. The same constituents were found in soil samples collected during the 1995 ESI conducted by the TNRCC in the area of the former tank farm.

Agency for Toxic Substances and Disease Registry Public Health Conclusion Categories
CATEGORY A.
URGENT PUBLIC HEALTH HAZARD

This category is used for sites that pose an urgent public health hazard as the result of short-term exposures to hazardous substances.

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.
PUBLIC HEALTH HAZARD

This category is used for sites that pose a public health hazard as the result of long-term exposures to hazardous substances.

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 long-term exposures (greater 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 a chronic 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 intervention.

CATEGORY C.
INDETERMINATE PUBLIC HEALTH HAZARD

This category is used for sites with incomplete information.

Criteria:
The limited available data do not indicate that humans are being or have been exposed to levels of contamination that would be expected to cause adverse health effects. However, data or information are not available for all environmental media to which humans may be exposed; and there are insufficient or no community-specific health outcome data to indicate that the site has had an adverse impact on human health.

CATEGORY D.
NO APPARENT PUBLIC HEALTH HAZARD

This category is used for sites where human exposure to contaminated media is occurring or has occurred in the past, but the exposure is below a level of health hazard.

Criteria:
Exposures do not exceed an ATSDR chronic MRL or other comparable value; and data are available for all environmental media to which humans are being exposed; and there are no community-specific health outcome data to indicate that the site has had an adverse impact on human health.

CATEGORY E.
NO PUBLIC HEALTH HAZARD

This category is used for sites that do not pose a public health hazard.

Criteria:
There is no evidence of current or past human exposure to contaminated media; and future exposures to contaminated media are not likely to occur; and there are no community-specific health outcome data to indicate that the site has had an adverse impact on human health.
