The worst-case scenario(s) and the alternate release scenario(s), including administrative controls and mitigation measures to limit the distances for each reported scenario. 
 
Population estimates are from the Census Bureau and take into account all persons within the toxic distance to endpoint perimeter. It is important to recognize, however, that the regulations require the identification of the potentially impacted population using a circle with a radius that is the maximum distance to the toxic endpoint. In reality, the released material would most likely take the form of a cloud or plume, impacting only a portion of the circle located in the downwind direction from the source.

Whenever possible, these components are installed in areas away and protected from material handling equipment to reduce the likelihood of damage. All parts are routinely inspected according to a schedule and defective or worn parts are promptly replaced. 
 
Storage vessels are installed in containment areas constructed of concrete walls and floors. The capacity of each area is of sufficient size to capture si 
gnificantly more than the contents of multiple vessels should a rupture occur from one tank compromising the integrity of another. Each storage vessel is routinely inspected according to the program schedule designed to reveal defects that may compromise safety. 
 
Materials stored within buildings are located in areas specific to their hazard class to prevent one group of hazard class from impacting another during an incident. 
 
All buildings are constructed of poured concrete walls and floors to minimize the possibility of a release contacting the ground and impacting the environment. Equipment used in the areas to move containers are designed for their intended use. 
 
Storage areas are routinely inspected according to a schedule to minimize risks associated with improper material storage. The local fire department routinely inspects all areas of the facility for code violations. 
 
Buildings are equipped with 24 hour monitoring systems to alert authorities of high heat, smoke and fire con 
ditions. Emergency responders are dispatched to the scene by a monitoring service. Intrusion is monitored after hours to prevent unauthorized access to the property. 
 
The grounds are secured to prevent unauthorized access and the company uses a security service present after hours to monitor the facility. 
 
Five-year Accident History 
 
There have been no accidents or incidents associated with the regulated chemicals during the past five years prior to the date of the plan. 
 
Emergency Response Program 
 
The emergency response program document and procedures were developed when the Environmental Protection Agency enacted the Superfund Amendment and Reauthorization Act known as the Emergency Planning and Community Right-To-Know Program or SARA Title III. 
 
This program requires facilities having certain regulated substances in amounts exceeding threshold quantities to notify the State Emergency Response Commission (ERC), Local Emergency Planning Committees (LEPC) and fire departments that wou 
ld respond to the facility in an emergency of the existence of these substances. 
 
This information is updated annually and made available to the public through the LEPC. Documentation includes the chemical inventory of regulated substances, the container types and storage conditions, maximum amounts at the site during the year, average daily amounts and the number of days on site. 
 
In addition, site descriptions, drawings of the facility, locations within the facility of each chemical, surface area, equipment locations as well as emergency equipment are included in the documents. 
 
The emergency response and contingency plan developed and coordinated with local responders includes a description of emergency response equipment on site, contacts names and phone numbers, procedures for public notice, guidelines for notifying emergency response agencies and personnel, information gathering forms and methods and reports that must be completed and filed with regulatory agencies. 
 
The employee 
emergency response training program is included with this document and is used by the facility to train personnel in response techniques. The program provides training for hazardous incident recognition, personnel protection equipment selection and use, characteristics of hazardous chemicals and the methods for response, cleanup and decontamination. 
 
Planned Changes to Improve Safety 
 
Plans are continually updated to improve management of chemicals and reduce the risks associated with handling chemical products. 
 
Plan updates are the result of coordination with local responders, inspections by regulatory agencies, training sessions, process changes and new risk management programs and regulations enacted by the government. 
 
Presently all areas are being studied to identify technically, procedurally and economically feasible passive and active risk management strategies to further enhance the safe operation of the facility.
