APPENDIX B: EXPLANATION OF COMPARISON VALUES
|
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. |

TABLE 9 - Exposure Pathway Elements
|
Pathway Name |
Contaminants of Concern | Source | Media | Point of Exposure | Route of Exposure | Exposed Population | Time | Comments |
| Potential Exposure Pathways | ||||||||
| Foodchain | Possibly PAHs | 1,2,3 | Fish / Shellfish | Sabine Lake and Intracoastal Canal | Ingestion | People who eat fish and shellfish caught in Sabine Lake and Intracoastal Canal | Past Present Future |
Indeterminate public health hazard since fish/shellfish tissue have not been analyzed. Sediments contain PAHs. |
| Air | Sulfur Compounds | Steam Boiler | Air | On- and off-site
|
Inhalation
|
Residents and workers | Past | Indeterminate public health hazard. In the past citizens complained about noxious odors that were traced to high sulfur content fuel oil used to fire a steam boiler. |
| Surface Water | PAHs | 2,3 | Surface Water | Sabine Lake and Intracoastal Canal adjacent to the site | Incidental Ingestion Dermal Contact |
People who use Sabine Lake and the Intracoastal Canal for fishing and other recreational activities | Past Present Future
|
No apparent public health hazard. Although contact with the surface water is possible it would most likely be minimal. Current contaminant concentrations are not known but are probably much lower that those documented during observed releases. |
| Surface Soil | Benzo(a)pyrene Beryllium Lead |
1,2,3 | Surface Soil | On-site | Incidental Ingestion Dermal contact |
On-site workers Trespassers |
Past Present Future |
No apparent public health hazard. Although people theoretically could contact contaminated soil, such contact would be minimal and infrequent. |
| Sediment
|
Benzo(a)pyrene (SE-08) | 1,2,3 | Sediment | On-site areas among barges on east side of State Marine Off-site south of State Marine and peninsula in Sabine Lake/Intracoastal Canal |

On-site workers Trespassers |
Past Present Future |
No apparent public health hazard. Although people theoretically could contact contaminated sediment, such contact would be minimal and infrequent. |

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: |
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: |
CATEGORY C. INDETERMINATE PUBLIC HEALTH HAZARD This category is used for sites with incomplete information. Criteria: |
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: |
CATEGORY E. NO PUBLIC HEALTH HAZARD This category is used for sites that do not pose a public health hazard. Criteria: |
