Executive Summary 
Scope and Purpose 
This manual has been prepared for Brown's Velvet Dairy in accordance with 29 CFR 1910.119, Process Safety Management of Highly Hazardous Chemicals, and 40 CFR 112 (r)(7), Accidental Release Prevention: Risk Management Plan. 
Stationary Source and Regulated Substances 
The stationary source is defined as the Brown's Velvet Dairy facility located at 1300 Baronne in New Orleans, Louisiana.  The facility is equipped with a refrigeration system that contains anhydrous ammonia, C.A.S.#7664-41-7.  Ammonia is the sole regulated substance with regard to the aforementioned regulations.  The maximum quantity of ammonia in the system is 7200 pounds. 
Accidental Release Prevention 
Releases are prevented by a combination of engineering and administrative controls.  Engineering controls include automated system shutdown when safe parameters are exceeded.  Administrative controls involve manual isolation and shutdown procedures to be performed by trained person 
nel.  The system is also equipped with pressure relief valves that operate to prevent damage to system components should pressures reach unsafe levels.  Operation of pressure relief valves will result in a controlled release of refrigerant. 
Worst Case and Alternate Scenarios 
Computer air models were run based on a worst case release scenario involving the catastrophic structural failure of the system receiver.  The receiver contains the largest quantity of ammonia in a single vessel.  Results of the model indicate that the toxic endpoint in this scenario would extend to a distance of .4 miles from the release site.  The urban character of the facility location indicates that surrounding residential population impact is minimal.  Primary receptors are retail, office and temporary lodging occupancies.  One environmental receptor, the Mississippi River, was identified within the radius defined by the toxic endpoint.  Likely alternate scenarios resulted in a toxic endpoint of less than . 
1 miles. 
5 Year Accident History 
The facility has experienced no immediately reportable releases of ammonia in the last five years 

Emergency Response Program and Policies 
Written emergency response procedures are maintained at the facility.  All employees are trained to act based on their pre-assigned roles during emergency situations.  A fully trained and equipped on-site emergency response team will mitigate unplanned releases.  In addition, Brown's Velvet has a contractual agreement with a third party response contractor to be notified of an uncontrolled release event. 
Planned Changes to Improve Safety 
Planned changes to improve safety at the facility include an aggressive inspection program and regular replacement of deteriorated system components.  In all cases, improved process technology is employed where feasible.  Existing levels of employee proficiency are enhanced by regular training and response exercises.
