Executive Summary 
 
The City of Muskogee, Oklahoma operates a water treatment plant located within the city limits in the northern portion of the city. The plant uses chlorine to treat the citys drinking water for the city. 
The water treatment plant holds safety as its first priority, especially w 
hen it comes to chlorine. The maximum inventory is 12 tons and the water treatment plant limits the maximum number of cylinders in use at any one time to four. 
 
The worst case scenario for Muskogee Water Plant is a 1 ton cylinder resulting in an estimated Level of Concern [LOC] of 1.2 miles using the National Safety Councils ALOHA mapping program. The first alternate scenario represents the severing of a transfer hose [whip] from the cylinder to the header pipe. This has an estimated LOC of 0.99 miles and a release of approximately 1000 pounds. This alternate is the release scenario that is most likely to occur. The second alternate scenario is a release representative of a culmination of both of the previous scenarios. This could occur if a tank ruptured and other tanks were able, due to failure of controls, to flow back along the header pipe and out the broken transfer hose [whip]. This would result in the release of approximately 1.5 tons of chlorine and result in a LOC footprint o 
f 1.4 miles.  
 
The Muskogee Water Plant follows a strict operation, safety and maintenance programs to minimize the likelihood of an accident occurring at the facility. Because of the strict implementation of the above-mentioned programs, this facility has not had a release within the last five years. 
 
 
The Muskogee Water Plant holds training and refresher courses for the personnel at the facility regarding the chlorine system and its concerns.  If an accident occurred, the Local Emergency Planning Committee [LEPC] and the Muskogee Fire Department would be notified and would respond immediately. 
 
The Muskogee Water Plant has no current plans to change the chlorine process in the foreseeable future.
