City of Elmhurst Wastewater Treatment Plant - Executive Summary |
GENERAL DESCRIPTION The disinfection process in use at the Elmhurst Wastewater Treatment Plant involves a train of six one-ton cylinders split into two headers that are connected by a single pipe to a chlorine injection diffuser. The two trains of three-one ton cylinders are connected to a header via capillary lines that are individually valved and can be removed from service one at a time. The two three-tank headers connect to a single line with a pressure induced transfer switch. If pressure is low on the tank side, the transfer switch will move to the higher pressure system. This transfer switch is also a backflow prevention valve. If a header that is not in use ruptures, gas from the in-use header cannot escape. This minimizes the numbers of tanks which may be venting to atmosphere in the event of a header rupture. When a transfer occurs due to on line tanks becomming empty, an alarm signals plant staff that the valve has activated. If the alarmactivates at an unexpected t ime or interval, staff are notified and can investigate the situation. Likewise, if a low pressure condition is found in the system, an alarm alerts staff to this condition. If this occurs at a time that is unexpected or too frequent an interval, staff will respond to it as well. The process room is equipped with a leak monitor that will alert staff in the event of excessive chlorine gas being present in either the storage or injection rooms. The chlorine injection system is a vacuum operated system meaning that in the loss of a vacuum diaphragms close which prevent the leak of gas to atmosphere. If a rupture occurs on the feedline to the injector or if a rupture occurs on the line from the chlorinator itself, only minimal gas will escape to the room. The entire system is designed to operate with a vacuum source. If the vacuum source is interrupted, gas flow stops. The entire process is in active use from May 1 to October 30 each year. From November 1 to April 30, the system remains in a standby mode and is used only as flows to the plant exceed plant capacity for secondary treatment. All maintenance performed on the tank systems including changing of tanks is performed with two staff members who are equipped with the necessary tools to stop a leak from the header or associated piping and are equipped with respirators and a supplied air system to allow them to work in a contaminated atmosphere in order to complete the necessary repairs. In addition to the six tanks that are connected to the train of two headers, there are three other tanks that are separate and are in a standby unconnected location. These tanks are replacements for empties and are not connected to the header in anyway. Valves are closed and cover plates are installed to protect the valves from any accidental damage. The entire building is dedicated to a single use without unusual traffic or other applications. The only time the building is in use or is occupied is when the chl orine system is being maintained or tanks are being changed. RESPERATOR TRAINING PURPOSE To provide training in the use and care of the Division respirator gear. SELECTION AND USE The Division is equipped with three types of respirators: A: a SCBA equipped with the pressure demand type regulator which is to be used in emergency situations where mobility is needed. The specific Division situations are CONFINED SPACE uses and CHLORINE (C12) or SULFUR DIOXIDE (SO2) leaks at the wastewater plant. B: the five minute escape bottle with the full enclosure head bag and pressure demand type regulator to be used while in a confined space when the atmosphere goes from safe to unsafe. C: the supplied air/hip pack system supplied with the pressure demand regulator. This system is to be used while working on C12 or SO2 tank changes at the WWTP. INSTRUCTION Annual training exercises shall be conducted with all Division staff. Training shall consist of use of all three types of respirat or gear used within the Division and in what specific situations they should be used. Supervisors will be responsible to monitor and instruct individuals on a regular (6-8 week) basis to be sure that proper procedures are followed when using the SCBA and/or supplied air system FIT TESTS All staff shall have the SCBA and Supplied Air masks fit tested to be sure that a good seal is achievable. Since this is impossible while wearing corrective lenses, they will have to be removed while wearing the face mask. A proper fit is also impossible if the user has sideburns or beard growth. The City will require all employees who may be required to wear respirator equipment to pass a fit test. Training on achieving a proper fit shall be done annually and be part of the regular training lesson plan. CARE OF EQUIPMENT Each person using the Division respirator equipment is responsible for the proper c are of the equipment. Before using, inspect the mask for signs of wear, cracking, scratched face plate, check the face seal for any sign of deterioration. Check the straps for tears or weakness. Check hoses and fittings as well as tank straps and supports. Reports any signs of damage to your supervisor. REMOVE ANY SUSPECT EQUIPMENT FROM THE WORK SITE AND DELIVER IT TO A SAFE REMOTE AREA, i.e., the Assistant Superintendent's office. After each use the user is responsible for the cleaning and disinfection of the face mask and shield. After cleaning, the user shall store the mask in the proper container ready for the next use. After each use the SCBA shall be returned to the storage compartment in the maintenance office. The five minute hip pack used with the supplied air system shall be kept in the C12 ready room. MAINTENANCE The City Fire Department will keep complete maintenance histories on all of the Division respirator equipment. Refills, tank tests, regulator repair and testing and all other maintenance checks shall be done at least annually. The Fire Department shall be responsible for scheduling maintenance and request delivery of the appropriate equipment to their facilities. HEALTH INSPECTIONS Regular health checkups shall be done on each person in the Division. Since anyone may be required to use the safety equipment, all shall be tested. Records of this testing shall be kept with the Respiratory Program file. Attached are emergency and standard operating practices to be used while handling chlorine. The respirator program is designed to be used in a chlorine and/or confined space environment. This program is intended to be a training tool to insure a complete review of all aspects of respiratory training. Whenever the respiratory equipment is needed, a two man "buddy system" shall be considered as being in place. NO INDIVIDUAL IS AUTHORIZED TO UNDERTAKE EMERGENCY REPAIRS ALONE. The only occasion in which one man will be using a res pirator is when escaping a dangerous environment with an emergency escape bottle as would be used in a confined space situation.

Geographic Location The Elmhurst Wastewater Treatment Plant is located at 625 South Route 83 in Elmhurst, Illinois, The plant facilities are on the east side of Route 83 set back from the roadway approximately fifty (50) feet. The main entrance to the facility is off of the East Frontage road accessible at Riverside Drive and Route 83. The plant is also accessible from the North on Route 83 at Highlan d. A total of sixteen (16) buildings are located on the facility's complex. The plant site is bordered on the north side by Salt Creek Sanitary District, the east side by Salt Creek and a residential area, the south side by business and commercial properties and the west side by Route 83 and a residential area. See Appendix 4 for site layout. Based on a hazard analysis, an Emergency Planning Zone (EPZ) has been established for the facility that extends from the facility to a distance of one-half mile. The size of this EPZ is based on the worst chemical at the facility. Specifically this EPZ is bounded on the north by Albert Street & the railroad tracks, the east by Hillside Avenue, the south by Washington Street and Wilson Street, and the west by Villa Avenue. General Description of off-Site Land Use The area located within the EPZ is primarily residential. There is, however, 20 structures with a special population that will require attention in the event of a release. These facilities are listed on Pages Two and Three. Likely Transportation Routes to and From the Facility The Elmhurst Wastewater Treatment Plant is served by the following transportation route: Route 83 It is over this route that the potential for a transportation accident is the greatest. Major Chemical Concerns The facility has indicated that it stores, handles, or manufactures the following extremely hazardous chemicals in excess of the EPA designated threshold planning quantity. These chemicals along with their potential hazards are listed below: Chlorine - Chlorine gas may cause severe irritation of the eyes,nose, and respiratory tract with tearing, and runny nose, sneezing, coughing, choking, and chest pain. Severe breathing difficulties may occur, which may be delayed in onset. Pneumonia may result. In high concentrations chlorine may irritate the skin and cause sensations of burning and prickling, inflammation, and blister formation. Any contact with liquid chlori ne may cause burns, blistering, and tissue destruction. Severe exposures may be fatal. Corrosion of the teeth, skin irritation, and reduced respiratory capacity may result from repeated or prolonged exposure. Sulfur Dioxide - It may cause death or permanent injury after very short exposure to small quantities. 1,000 ppm causes death in from 10 minutes to several hours by respiratory depression. It is an eye and respiratory tract irritant, Persons with asthma, subnormal pulmonary functions or cardiovascular disease are at a greater risk. DETECTION, NOTIFICATION, AND WARNING SYSTEM If the incident involves the potential or actual release into the environment of a CERCLA/SARA designated hazardous material, in excess of the reportable quantity, then the Facility Emergency Coordinator, or his designee, will classify the incident and then notify, via telephone, the local Fire Department, Local Emergency Coordinator, and the State Emergency Response Commission. A call to 9-1-1 will sat isfy the requirement of notifying the jurisdiction's Fire Department, The numbers for these notifications are shown on the front page of this document. Verbal notification of these agencies will be accomplished using the Chemical Accident Reporting System (CARS) form, The CARS Form, and instructions for its use are shown in Appendix 5. The use of this form will ensure that all parties involved in the emergency transmit and receive information in a uniform format that is easily understandable. When a chemical release occurs at the facility, plant management and employees are alerted of the problem through an alarm system consisting of flashing lights and alarms. Gas sensors, located in the chlorine storage room, are tied to an alarm system in the control room. If an alarm sounds, the facility operator alerts on-site personnel and provides notification of the community by calling 9-1-1. The 9-1-1 operator, at DuComm, will notify the Elmhurst Police and Fire Departments, the Villa Pa rk Police and Fire Departments and the Illinois State Police District 2 in Elgin. If warning of the public is necessary, it will be accomplished through the use of a route alerting system utilizing mobile public address systems on available police, fire and emergency vehicles. Additionally radio station WDCB-FM (90.9) will be utilized as the Emergency Broadcast System (EBS) station for the DuPage County area, This station will be used to transmit news and official instructions from local levels of government to the general public. Activation of this system will be accomplished through the DuPage County Office of Emergency Management. ACCIDENT CLASSIFICATION SYSTEM Response to a fixed-site hazardous materials incident will be accomplished in a manner that is consistent with the severity of the incident. Therefore an accident classification system has been established. Response to the incident, as outlined in Appendices 1 and 2, will be triggered by level of classification as de fined below. THIS IS A SUMMARY OF THE EMERGENCY RESPONSE PLAN FOR THE CITY OF ELMHURST WASTEWATER TREATMENT PLANT. THE ELMHURST FIRE DEPARTMENT IS THE AGENCY RESPONSIBLE FOR EMERGENCY RESPONSESAND WILL BE CHARGED WITH IMPLEMENTING ANY EVACUATION PLANS. THE PLAN IN ITS ENTIRETY IS AT THE ELMHURST FIRE DEPARTMENT AND AT THE ELMHURST WASTEWATER TREATMENT PLANT. RAINING, TESTING AND REVIEW RECORSD ARE KEPT AT THE ELMHURST CITY HALL. |
