   RISK MANAGEMENT SUBMISSION STATEMENT 
 
Atlanta Frozen #121 
385 Grant Circle S.E. 
Atlanta, GA 30315 
 
This is to inform all interested persons, including  
employees that Atlanta Frozen #121, Atlanta, GA is  
complying with OSHAs Process Safety Management Standard  
(called Process Safety Management or PSM), Title 29 Code of  
Federal Regulations (CFR) 1910.119, and EPAs Risk  
Management Program regulations (called RM Program), Title  
40 CFR Part 68, to deal with the risks involved with the  
storage, handling, and processing of hazardous chemicals.  
In this way we promote overall plant, worker, and public  
safety. These programs enable our facility to prevent the  
occurrence, and minimize the consequences, of significant  
releases of toxic substances as well as fires, explosions,  
and other types of catastrophic accidents. Overall, these  
programs prevent accidental fatalities, injuries and  
illnesses and avoid physical property damage. 
Our safety programs are applied to any activity invo 
lving  
hazardous chemicals including any use, storage,  
manufacturing, handling, or the on-site movement of such  
chemicals, or combination of these activities. Any group of  
vessels which are interconnected and separate vessels which  
are located such that a hazardous chemical could be  
involved in a potential release shall be considered a  
single process. 
 
Our safety programs prevent accidents because they focus on  
the rules, procedures, and practices which govern  
individual processes, activities, or pieces of equipment.  
These rules are detailed and improved as necessary. They  
are also communicated to and accepted by all employees at  
the facility. 
 
DESCRIPTION OF PROCESS 
 
The Atlanta Facility is an ice cream processing, freezing, and storage 
facility.  The facility uses ammonia in an industrial refrigeration system 
to maintain temperatures in milk tanks, coolers, and freezers. The  
refrigeration system is also used to freeze ice cream. 
Ammonia refrigeration is the only process s 
ubject  
to the Risk Management Legislation. In addition there is a computer  
control system that monitors temperatures, pressures, and the  
atmosphere for leaks.  
 
 
WORST CASE SCENARIO 
 
Failure of the high pressure receiver containing 7150 lbs.  
of ammonia with the receiver quantity limited to 80 % of  
the vessel capacity by facility procedures resulting in a  
ten minute release. Under worst-case weather conditions,  
ammonia could travel 1.0 miles before dispersing enough to  
no longer pose a hazard to the public. This scenario is  
unlikely for the following reasons: worst- case weather  
conditions are uncommon; the vessel is enclosed in a  
building that would withstand and help to contain such a  
release; industry standards for the manufacture and quality  
control of pressure vessels; ammonia is not corrosive in  
this service; pressure safety valves limit operating  
pressure in this vessel; the accident prevention program in  
place at the facility including the mechanical integrity  

rogram for regular maintenance, inspection and testing,  
and replacement of equipment, if necessary; installed  
ammonia sensors in the system to warn of leaks; alarms and  
the auto-dialing system in place to warn operating  
personnel of process upsets; and the emergency response  
plan and equipment in place at the facility. 
 
 
ALTERNATIVE RELEASE SCENARIOS 
 
Failure of a 3/4 pipe on the suction accumulator would  
result in a release of 2886 lbs. of ammonia over a time period  
of sixty minutes. Under common weather conditions, ammonia  
could travel .1 miles before dispersing enough to no longer pose  
a hazard to the public. This particular line was chosen as  
an alternative scenario because it is in an area of the  
plant where it could be struck and result in a release.  
This scenario is unlikely for the following reasons: all  
forklift travel in this area is restricted; the facility  
accident prevention program in place at the facility  
including operating procedures to have personnel p 
resent at  
all times during any forklift use, and the mechanical  
integrity program for regular maintenance, inspection and  
testing, and replacement of equipment, if necessary; and  
the emergency response plan and equipment in place at the  
facility. 
 
 
ACCIDENT HISTORY 
 
There were no reportable accidents in the past five years. 
 
EMERGENCY RESPONSE PROGRAM 
 
This facilitys emergency response program is based on the  
OSHA requirements for Emergency Action Plans (29 CFR  
1910.38 and 1910.119) and HAZWOPER (29 CFR 1910.120). We  
have trained employees for emergency response and maintain  
a written emergency response plan. 
 
This plan is coordinated with the Local Emergency Planning  
Committee (LEPC) and the local fire department. We conduct  
annual drills for implementation of the emergency response  
plan at the facility with the participation of the LEPC and  
the fire department. The facility is equipped with a siren  
to warn plant personnel of an emergency. The last training at  
the plan 
t was on March 5, 1999.
