The mission of the Fort Collins Water Treatment Facility (FCWTF) is to "provide the community with a continuous ample supply of treated water that is pleasing, wholesome, free from known health risks, and affordable. The FCWTF purchases products by determining best value for the City. Best value is calculated by combining the following four components: (1) the chemical has been tested in the Pilot Plant and/or approved by the Water Treatment Quality Coordinator; (2) the chemical can meet or exceed all FCWTF standards, the AWWA standards, the NSF standards, and any other regulatory agency standards; (3) the supplier can meet all the FCWTF requirements; and (4) the cost is factored in once it has been determined that a supplier can meet items (1), (2), and (3) above. HEALTH AND SAFETY ISSUES For detailed information, please refer to the most current MSDS document 1. CO2 is primarily an oxidizer. Other hazard classes include being classified as a cryogenic. 2. NFPA Hazard Rating includes: Health=1 • Flammability=0 • Reactivity=0 • Special=Oxidizer 3. Personal Protective Equipment: Gloves for cryogenic atmospheres. Goggles or a full -face shield. Carbon dioxide portable analyzer. For spill clean up, SCBA's should be worn. 4. Delivery vehicles: Trucks leaking any liquids, powders, substances, etc.; will not be allowed on FCWTF property. All trucks must use chock blocks on tires; these blocks will be supplied by FCWTF. 5, Delivery Containers: In accordance with the most current AWWA Standard for liquid carbon dioxide, the CO2 bulk shipment containers will be pressure vessels manufactured to American Page 1 K:/Operate/SOP/Carbon DioxidelCarbonDioxidePurchases.doc City of Fort Collins Water Treatment Facility Fort Collins �. UU�ti Standard Operating Procedure sernces Purchasing Liquid Carbon Dioxide Society of Mechanical Engineers (ASME) pressure vessel code and comply with the U.S. DOT regulations for hazardous materials. INFORMATION FOR THE FORT COLLINS WATER TREATMENT FACILITY (FCWTF) 1. CO2 is budgeted in account 502-032201-534260. 2. CO2 is used in the FCWTF Corrosion control program. CO2 and Lime are combined at the pre treatment and the clearwell stage to add alkalinity and hardness to the water and thereby provide corrosion control. 3. FCWTF requires CO2 to have a minimum of 99.5 percent purity. 4. FCWTF requires CO2 to be delivered in bulk quantities. 5. FCWTF has storage capacity for 380,000 pounds of carbon dioxide. There are two 160,000 pound liquid storage tanks and one 60,000 pound storage tank. 6. FCWTF requires that CO2 be delivered within 48 hours of an order. A. FCWTF has used over 5,000 lbs. of CO2 in one day. FCWTF protocol requires the container to be between 15,000 and 10,000 lbs. before delivery. A container with only 10,000 lbs. limits FCWTF to 2 days of CO2. 7. FCWTF will reject delivery of any bulk shipments which appear to be leaking, forming ice on the outside of valves, or have any damaged piping, tubing, hoses, or fittings. The Supplier will pay the freight charges for all rejected shipments. CO2 1. CO2 must meet the most current American Water Works Association (AWWA) Standard for liquid carbon dioxide. A. Commercial carbon dioxide suitable for use will have a carbon dioxide content of at least 99.5 percent, by weight. B. CO2 shall contain no soluble inorganic or organic substances in quantities capable of producing deleterious or injurious effects on the health of those consuming the water or that would otherwise render the water that had been treated properly with CO2 unfit for public use. a. Potential impurities include: hydrocarbons, hydrogen sulfide, nitrogen dioxide, ammonia, radon, and sulfur dioxide. C. Water content of CO2 shall not exceed 220 ppm (volume per volume (v/v)-32°F) at the time of delivery. SUPPLIER 1. Supplier must be able to supply CO2 in bulk quantities. 2. Supplier must be able to supply CO2 within 48 hours of the telephone order. 3. Supplier must provide an analysis of impurities with each shipment. The analysis shall be submitted prior to delivery. The analysis should include, but is not limited to: acetaldehyde, benzene, carbon monoxide, carbonyl sulfide, hydrogen sulfide, hydrogen, methane, moisture, X [YfH Page A:/Operate/SOP/CarbonDioside/CarbonDioxidePurchases.doc �fert �`s City of Fort Collins Water Treatment Facility Fart Collins Standard Operating Procedure Sernces Purchasing Liquid Carbon Dioxide other hydrocarbons, oxygen, radon, and sulfur dioxide.
