5.0 RISK ASSESSMENT
An evaluation of the health risk associated with the plant's vinyl chloride emissions was conducted by comparing the results of the modeling analysis to the the health effects data presented in "Toxicologi cal Profile for Vinyl Chloride" which was prepared by the U.S. Public Health Service in collaboration with the U.S. Environmental Protection Agency. This report was published by the Oak Ridge National Laboratory.
It is important that the analysis presented in the above referenced report is based on animal studies and extrapolated to humans. As such, it is extremely conservative. It has been estimated that this report presents risk levels which are 3 to 4 orders of magnitude more conservative than other studies which are based on human health risks directly.
For long term exposure (24 hours per day, 365 days per year) the following concentrations and risk levels were derived:

1.0 INTRODUCTION Scott Environmental Technology, Inc. was contracted by Vista Polymers Company in Aberdeen, Mississippi to conduct a comprehensive dis persion modeling study for vinyl chloride which is emitted from the Vista plant. Modeling was conducted to determine the predicted short term and long term ambient air quality impacts of these emissions in the area around the plant. Presented in this report are the results of this modeling study. Presented also, is a discussion of the modeling procedures which were used.

3.0 MODELING PROCEDURE
All modeling was conducted using the UNAMAP-6 versions of the Industrial Source Complex Short Term (ISCST) and Long Term (ISCLT) disper sion models. Five years of meteorological data from the Columbus Air Force Base were used as model imput data.
Modeling was conducted using the ISCST model to determine the downwind 1-hour average concentrations of vinyl chloride. The ISCLT model was used to predict annual average concentrations.
All models were run in the regulatory default mode. Terrain heights were not evaluated because of the very flat nature of the area around the plant. A 162 polar receptor grid was established around the plant. Receptors were located at 20 degree intervals at downwind distances of 100, 130, 200, 300, 400, 500, 700, 1000, and 1500 meters.
Upon completion of each model, two and three dimensional plots of the predicted pollutant concentrations were prepared in a 2,000 meter x 2,000 meter grid using the EPA UNAWA? Graphics Package. The plant property is drawn in and blanked out on the two dimensional plots.

SET 1913-01-0788 2.0 PLANT DESCRIPTION
The Vista Polymers plant is located on Highway 25 in Aberdeen, Mississippi. The plant measures approximately 750 meters in length and 450 meters in width. It is bordered on the east and west sides by other indus trial properties, on the north side by Highway 25 and on the south side by undeveloped areas. The plant is located in an area which is surrounded by level terrain.
Various procedures at the Vista facility emit vinyl chloride to the atmosphere. Current (1988) point source, volume source, and area source emission rates were estimated by Vista personnel. Table 2-1 presents a listing of all emission sources along with their physical parameters which were used as data input for this modeling study.

5.0 RISK ASSESSMENT
An evaluation of the health risk associated with the plant's vinyl chloride emissions was conducted by comparing the results of the modeling analysis to the the health effects data presented in "Toxicologi cal Profile for Vinyl Chloride" which was prepared by the U.S. Public Health Service in collaboration with the U.S. Environmental Protection Agency. This report was published by the Oak Ridge National Laboratory.
It is important that the analysis presented in the above referenced report is based on animal studies and extrapolated to humans. As such, it is extremely conservative. It has been estimated that this report presents risk levels which are 3 to 4 orders of magnitude more conservative than other studies which are based on human health risks directly.
For long term exposure (24 hours per day, 365 days per year) the following concentrations and risk levels were derived:

SET 1913-01-0788 4.0 MODELING RESULTS
The maximum predicted downwind ambient pollutant concentrations and their locations are presented in Table 4-1 for the emission rates and time periods which were modeled. The modeling results are shown graphically on the plots which follow Table 4-1. The plots are presented in the same order as the information appears in Table 4-1. These plots show.there is no one primary impact area of the plant's emissions. This is due to the generally light winds in the Aberdeen area.
