IV. OVERVIEW OF AGENDA

Ms. Rich met the EPA and EC/R representatives at the Courtyard by Marriott Hotel on 

Regent Boulevard in Irving, Texas. She then led the group on a driving tour of the area to point 

out the locations of various oil (condensate) and gas wells, tank batteries, and compressor 

station. Figures 1 through 7 provide a photographic summary of the driving tour of these sites. 

During the drive, Ms. Rich noted that some of the larger environmental issues were corroded 

tanks and loading and unloading of produced water and condensates.

After the drive, the group met with Mr. Tillman at the Courtyard by Marriott Hotel. Mr. 

Tillman stated that DISH currently has 5 companies operating 11 natural gas compressors. In 

addition, he noted that there also condensate/produced water tanks, amine treaters, and glycol 

dehydrators in the area. He believes a big issue in the town is the proximity of these process 

units to residences. He also stated that the Indian tribes in the area have similar issues. 

Mr. Tillman showed the group a sample of the town’s tap water that has sediment at the 

bottom of the container. He stated that the State has done some tests on the water and found that 

many of the residences had water quality issues. He would also like to see some air monitoring 

in the town.
