Executive Summary 
It is the policy of the City of College Station, Texas, to operate safe water and wastewater treatment facilities, reducing to the greatest extent possible any hazards associated with our processes, and reducing any subsequent risk to the surrounding community, our employees, and the environment. It is also our policy to work with the surrounding community and local emergency response agencies, and promote a spirit of cooperation and teamwork, to orchestrate an effective contingency plan in the unlikely event that a process incident occurs at one of our plants. 
Primary Activity 
The primary activity at the Dowling Road Pump Station is municipal water disinfection and distribution. 
Use of Regulated Substance 
Chlorine is used primarily as a disinfectant prior to distribution in the drinking water supply. 
Quantity Handled or Stored 
Chlorine: 18,000 pounds 
Worst-Case Release Scenario 
Failure of a ton container of 2,000 pounds of chlorine; 10 minute release mitigated by a f 
actor of 0.55 because the process is sheltered by a building.  Under worst case weather, chlorine could travel 1.55 miles before dispersing enough to no longer pose a hazard to the public. 
Alternative Release Scenarios (ARS) 
Failure of a vacuum regulator check unit in the open position.  The release would be mitigated by an enclosure, resulting in a release rate of 5.8 pounds per minute, and an offsite distance of 0.26 miles.  This is about the most realistic release that would ever be expected to occur.   
Accidental Release Prevention Program and Chemical-Specific Prevention Steps 
The Dowling Road Pump Station is in compliance with the RMP Rule, 40 CFR 68.
