PURPOSE AND SCOPE

The purpose of this plan is to provide information to the employees of St. Lawrence University regarding response to an accidental release of anhydrous ammonia from the refrigeration system at Appleton Arena and safeguard the employees, students and the public in the event of an emergency. This plan applies to all employees of St. Lawrence University (including part-time employees, student employees, and contractors working onsite) who are involved in the maintenance of, or emergency response associated with the Appleton Arena refrigeration system.

RESPONSIBILITIES

Appleton Facility Manager (Bruce Streeter): o Ensures employees and refrigeration contractor (Siemens) are familiar with the plan. o Inspects the ammonia sensor and ensures repairs are made.

EH&S o Schedules ammonia sensor test and PM with NCC (alarm system contractor)

o Keeps log of 6 month calibration test by NCC and activation test checklist (see Appendix H)

Heating Plant Manager: o Ensures that exhaust fan and fresh air louver are operational and working in

conjunction with an ammonia sensor activation.

Chemical Hygiene Officer: o Reviews the Ammonia Contingency Plan annually in consultation with those

concerned. o Oversees the effective implementation of the Ammonia Contingency Plan

Assistant VP of Safety & Security & Emergency Management o Liaises with the fire department.

NCC o Conduct semi-annual testing of ammonia alarms and replace sensors per

manufacturers recommendations. GENERAL

The ice rink is open between August 20 and March 20. The ammonia system is located in the compressor room in Appleton Arena which is accessed from the north parking lot through the large overhead door or through the interior hallway. The refrigerant system has two compressor units, which are regularly maintained. It contains 300 lbs. of anhydrous ammonia (NH3). Three additional cylinders holding a total of 300 pounds of anhydrous ammonia are also stored in the compressor room. Drawings of Appleton Arena with refrigeration system layout are in Appendix A.

AMMONIA ALARM SYSTEM

The compressor room is equipped with a pair of gas sensors for detection of ammonia leaks mounted on the electrical panel to the right of the compressors.

The system alarm works as follows:

The alarm will activate an audible and strobe alarm by the compressor room overhead door and a second audible and strobe alarm above the interior compressor room door when the ammonia concentration reaches 100 ppm. This alarm is a warning to evacuate Appleton Arena. The Security Office will receive notice indicating there is an ammonia leak. When there is an activation of the ammonia sensor; both zone 1 (fire alarm) and zone 4 (ammonia) will appear in the dispatch office screen. When in alarm the room exhaust fan will turn on and the fresh air louver will open to remove leaked ammonia from the compressor room. Employees may not

enter the compressor room once the alarm has been activated.

If an ammonia smell is detected outside Appleton Arena, emergency phones located in the Appleton office at the opposite end of the building, can be used to inform Safety and Security (x5555)

If the alarm system malfunctions the facility manager will take immediate steps to return it to service and advise Safety & Security, EH&S and all Appleton staff that the system is out of service.

RESPONSE

Upon activation of the alarm, the Safety & Security dispatcher is alerted and will in turn immediately contact the County dispatcher at 911 and send a patrol officer to the scene to assist as directed. Safety & Security will dispatch the Maintenance Contractor and the Facility Manager. They will next contact the Director of Facilities Operations. Melissa Farmer Richards or Ryan Deuel (University Communications) and Suna Stone-McMasters or Nick Ormasen (Environmental Health and Safety), will also be notified by the dispatcher as soon as possible after the response has been initiated. The Facilities on-call manager will contact NCC to dispatch a technician to confirm proper reset and operation of the ammonia alarm system.

All building occupants will evacuate the space regardless of any event in progress. The Incident Commander (or their designee) will be in charge of the response and direct any evacuation of the building and outside area. Emergency evacuation routes are posted throughout the building. Security and Facilities staff working in the arena shall remain available to assist in directing the evacuation by posting themselves at the exits of the building. Staff not on duty may be called in to assist in the event of a serious emergency.

An emergency ammonia release valve and refrigeration equipment power shut-off switch are located in a locked red box mounted 8 feet up on the west wall, adjacent to the exterior Compressor room door. (See photo in Appendix A.) In case of an emergency, Canton Fire & Rescue or the St. Lawrence County Hazmat Team will open the valve and shut down the system.

An event such as a major fire near the compressor room or a large discharge from the ammonia refrigeration system poses a health hazard to people in the vicinity. The Incident Commander, most likely the Canton Fire Chief, would decide on the need to activate the Village of Canton Disaster Plan for an evacuation and activate the ammonia release valve. The map provided in Appendix B delineates an isolation zone of 200 ft in all directions and an evacuation zone of zone of 0.4 miles (DAY) or 1.4 miles (NIGHT) to safeguard people who could be affected from a discharge from the ammonia refrigeration system.

COMPRESSOR SHUTDOWN

There are two (2) emergency shutdown switches for the system: In the compressor room; The Central Heating Plant

There are also four (4) yellow ammonia isolation valves located in the compressor room. See Appendix C for a photo of these valves. A wrench for closing the valves is kept chained in reach of the valves.

If the alarm sounds, any individual wearing proper PPE and trained to do so may shut down the system.

NRC NOTIFICATION

The CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act) designated ammonia as a hazardous substance. The Reportable Quantity (RQ) is 100 lb. (45.4 kg). The Facility Manager, Director of Facilities Operations or Chemical Hygiene Officer is required to notify the National Response Center (NRC) immediately when there is a release in an amount equal to or greater than the RQ. Toll free (800) 424-8802.

REGULAR INSPECTIONS AND MAINTENANCE ACTIVITIES

From August 20th to March 20th the ice rink is open. The Appleton Facility Manager (or designee) conducts daily visual inspections of the ammonia compressor room, and completes a daily record report kept in this room, See Appendix D. After March 20th when the rink is closed, a technician from Siemans closes the valves. Gas pressure in the compressors is continuously monitored in the heating plant year-round.

The ammonia sensors must be tested per manufacturer’s recommendations with certified calibration gas every six months or after major exposure to a leak. A simulated response activation should be completed in conjunction with the calibration testing every six months or following a leak. NCC will complete during their semi-annual inspections as outlined in Appendix E . EH&S will schedule the six month calibration testing with NCC and verify that the appropriate

check list has been completed (see checklist Appendix F). The check list includes all items which need to be initiated during a simulated ammonia alarm (ventilation system functioning, fire alarm functioning & reporting, horn & strobes etc..). Any deficiencies identified during the testing will be reported to EHS immediately and EHS will work with the appropriate Facilities Managers to correct all deficiencies . Sensors will be routinely replaced by NCC once every 24 months, NCC will maintain the replacement schedule in their service system and is responsible for scheduling this inspection. Replacements will be staggered by 12 months to provide redundancy and ensure that coverage is now lost due to sensor maintenance or failure.

Employee Training and Exercises. Any employee who may be involved in the maintenance of, or an emergency response associated with, the refrigeration system must be trained and qualified for their responsibilities. These

employees include Grounds, Security, Skilled Trades, or other Facilities Management personnel, and supervisors of those employees. New employees whose job requires them to work in the arena shall be trained by their supervisor within one week of their arrival.

Trained employees shall undergo a brief annual refresher conducted and documented by the EHS Manager to review the response plan and assess any changes noted in the course of the year. If there are significant changes in the system, alarms or emergency response procedures, updated training for all involved personnel will be conducted at the time of the changes. In addition, certificates of training for Siemens contract employees, and an updated copy of their contractual service agreement, are kept on file by Facilities Management.

NATURE AND HAZARDS OF AMMONIA

Ammonia (NH3) is a colorless gas, with a penetrating, pungent, and suffocating odor. It easily dissolves in water to form a caustic solution called ammonium hydroxide (NH4OH), sometimes referred to as aqueous ammonia. Ammonia has a vapor density less than air and will rise when released, but it will readily react with moisture in the air, become heavier and sink to the ground

The table below describes some chemical characteristics of ammonia and ammonium hydroxide. PHYSICAL CHEMICAL
