GLOSSARY/ACRONYMS

Lincoln Creosote Site
Glossary

ATSDR:
The Agency for Toxic Substances and Disease Registry. ATSDR is a federal health agency in Atlanta, Georgia that deals with hazardous substance and waste site issues. ATSDR gives people information about harmful chemicals in their environment and tells people how to protect themselves from coming into contact with chemicals.

CERCLA
:
The Comprehensive Environmental Response, Compensation, and Liability Act was put into place in 1980. It is also known as Superfund. This act concerns releases of hazardous substances into the environment, and the cleanup of these substances and hazardous waste sites. ATSDR was created by this act and is responsible for looking into the health issues related to hazardous waste sites.

CCA

Copper-Chromium Arsenate

Comparison Value (CVs)
:
Concentrations or the amount of substances in air, water, food, and soil that are unlikely, upon exposure, to cause adverse health effects. Comparison values are used by health assessors to select which substances and environmental media (air, water, food and soil) need additional evaluation while health concerns or effects are investigated. Also known as HAC (Health Assessment Comparison)Values.

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 USEPA's cancer slope factors (CSFs).

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).

LTHA

The Lifetime Health Advisory represents a contaminant concentration that USEPA considers to be protective of noncarcinogenic health effects during a lifetime (70 years) of exposure.

LTR

Louisiana Tumor Registry

MRL

Minimal Risk Level. An estimate of daily human exposure - by a specified route and length of time -- to a dose of chemical that is likely to be without a measurable risk of adverse, noncancerous effects. An MRL should not be used as a predictor of adverse health effects.

NPL

The National Priorities List. (Which is part of Superfund.) A list kept by the U.S. Environmental Protection Agency (EPA) of the most serious, uncontrolled or abandoned hazardous waste sites in the country. An NPL site needs to be cleaned up or is being looked at to see if people can be exposed to chemicals from the site.

OPH

Office of Public Health

PAH

Polycyclic aromatic hydrocarbons

PCP

Pentachlorophenol

PELs

Permissible exposure limits

PHA

Public Health Assessment. A report or document that looks at chemicals at a hazardous waste site and tells if people could be harmed from coming into contact with those chemicals. The PHA also tells if possible further public health actions are needed.

PNAs

Poly nuclear aromatics

ppb

Parts per billion

ppm

Parts per million

PRP

Potentially Responsible Party. A company, government or person that is responsible for causing the pollution at a hazardous waste site. PRP's are expected to help pay for the clean up of a site.

Reference Dose (RfD)

An estimate, with safety factors (see safety factor) built in, of the daily, life-time exposure of human populations to a possible hazard that is not likely to cause harm to the person.

RMEG

Similar to the EMEG but derived from USEPA's reference dose. It is the concentration in a specific media at which daily human exposure is unlikely to result in adverse noncancerous effects.

PUBLIC COMMENTS

Public Comments on the Lincoln Creosoting Company Site Public Health Assessment

The following questions and comments were gathered from oral and written statements on theearlier release of the public health assessment (PHA), from health concerns raised in other publicmeetings, and from health questions that were submitted to OPH/SEET. Similar questions andcomments have been combined together and others have been summarized.

Comment # 1:
The Public Availability Outreach Session did not include every household represented on theLincoln Creosote Site. It seems that many were left out, therefore the accuracy of conclusionsreached should be further evaluated.

OPH/SEET Response:
The survey was targeted to residents of the Northpark Apartment Complex because of the prioromission of input from these residents. This complex is located in close proximity to the site.Previous efforts were focused on owners of dwellings on the site. The survey was used to help give background on the site, and to documents the ideas and concerns of these residents. Noconclusions were drawn from this survey.

Comment # 2:
Residents expressed concern about children still playing in the ditches near the NorthparkApartment Complex.

OPH/SEET Response:
Due to the nature of this site, it is difficult to determine if, in spite of remedial efforts, the ditches are clean enough to accommodate all segments of the population. Due to this fact, and the hazards inherent in playing in urban ditches, OPH/SEET recommends that children stay out of the ditches. (See the Community Health Concerns Section of the Document, Question #1.)

Comment # 3:
Residents expressed concern about eating vegetables grown in local gardens.

OPH/SEET Response:
Because of the remediation that has occurred at this site, the contaminated soil has been replaced. Food grown in local gardens is safe to eat. (See the Community Health Concerns Section of the Document, Question #6.)

Comment # 4:
Residents expressed concern about allergies, asthma, and airborne particles.

OPH/SEET Response:
Asthmatic episodes and respiratory problems may, at times, be triggered by fumes, odors, andparticulate matter in air. The site conditions in the past may have contributed to odors and dusts arising form the site, which may, in turn, have aggravated respiratory conditions. The remediation and vegetation of the site was instrumental in solving that problem; however,individual health issues should be discussed with a physician. (See the Community HealthConcerns Section of the Document, Question #5.)

Comment # 5:
Residents expressed concern about the potential for decreasing property values.

OPH/SEET Response:
The Lincoln Creosote Site was remediated by the Joslyn Corporation under EPA supervision. Inthe past, at other sites, EPA sent out letters informing residents of the remediated status of their properties; however, the remediated status in itself should negate a decrease in property value.

Comment # 6:
Would exposure to site chemicals cause cancer in the residents?

OPH/SEET Response:
The Louisiana Tumor Registry has data on the cancer incidence for the area. These data areanalyzed in the Health Outcome Section of this document. Overall, cancer incidence rates for thecensus block groups, surrounding the site were lower than or along with expected when comparedwith the region. (See the Community Health Concerns Section of the Document, Question #11.)
