The contractor is responsible for conducting inventory of all Contractor provided equipment and supplies and maintaining a thirty day minimum supply in the Boiler Plant or in a location as directed by VA at all times. All required supplies will be delivered to the boiler plant within fourteen days of inventory. The contractor is subject to 24/7 emergency call in. The average untreated water quality results are as follows; Incoming Raw Water Conductivity = 250 us/cm, Hardness = 8 grains per gallon or 130 ppm and PH = 6.8 Makeup Water (soft) Hardness = 1ppm. All Condensate Returns PH = 6.8, Hardness (can range) 0 to > 60 ppm Surge (Condensate Return Storage) Tank Conductivity (can equal incoming raw water), Hardness (can exceed 130 ppm). Note; this water is transferred to the Deaerator and then becomes Feed Water. Average Makeup Water used = 2,500 to 4,500 gallons per day (depending on season) or 15%. Chemical Water Treatment Contractor Qualifications: The contractor must operate (or continuously maintain a contract with) a state certified laboratory to perform complete scientific analyses of water chemistry, deposits, metallic materials affected by corrosion, and provide recommendations for correction of problems related to the water treatment program. Any personnel changes must be submitted and approved by the Contracting Officer prior to change. Chemicals and Testing Supplies -Tasks: Provide; with exceptions listed in the Introduction; all chemicals, test kits, test apparatus and reagents and instructional materials as necessary to comply with all contract requirements. Deliver to the Contracting Officer s Representative, hereinafter designated as COR. Chelate-based chemicals are not permitted. The contractor s list of potential treatment chemicals shall be provided for VA approval. All chemicals utilized must conform to FDA guidelines: CFR 21, 173.310, BOILER WATER ADDITIVES PERMITTED IN PLANTS WHERE STEAM CONTACTS FOOD. In addition, the chemicals shall conform to all local, state, and federal government regulations on water pollution, and have appropriate EPA registration. The VAMC utilizes boiler steam for food preparation, for humidification, and for surgical equipment sterilization. Furnish refillable onsite chemical storage containers with secondary containment for liquid chemicals if space is available to support the use of these. If providing individual drums of treatment chemicals the maximum size is 15 gallons (this is the current method utilized and must be retained until the end of the plant upgrade project now in progress). If dry form chemicals are provided the maximum size is 50 lbs. No assistance from VA personnel will be provided to deliver chemicals to the place of storage except to provide access. Submit MSDS sheets for all chemicals utilized during the performance of services under this contract. The MSDS sheets will accompany delivery of the chemicals. With no exceptions, MSDS must accompany each delivery. The chemicals will not be handled by VA employees until such MSDS is received onsite by the COR and/or Boiler Plant Work Leader. All chemical containers shall be labeled with complete information on the contents and shall be returnable. Containers with missing labels will not be accepted and shall be removed from the site by the contractor when notified. All bulk containers requiring hazardous waste disposal remain the property of the contractor and must be immediately removed from the site when they are no longer needed at the site. The contractor shall be responsible for disposing of any and all contaminated materials which require special disposal, and it shall be the contractor s expense. The contractor shall be present during all annual boiler inspections to provide any explanation to the professional boiler inspector concerning the water treatment and conditions of equipment associated with water treatment. These inspections are currently conducted in March, April and May of each year; however, they might occur at different times as determined by VA. The VA will notify Contractor no less than 30 days prior to a scheduled inspection. Performance Requirements: All tests possible shall be performed utilizing the VA owned HACH DR850 or newer Colorimeter. The stated test limits and ranges for the specified test are suggested but may be adjusted as needed unless otherwise stated. All test specified shall be performed. All stated test are to be performed once per month by the Contractor. The Contractor shall perform these test every fourth week. VA test frequencies as stated. Prevent all damage of boiler pressure vessels and systems related to water treatment as evidenced by visual inspections and test reports. There shall be no pitting or corrosion as measured by visual inspections of internal boiler water side metals and systems piping. The contractor must maintain control of corrosion rates. Steel corrosion rates shall be less than 2.0 mils per year. Copper corrosion rates shall be less than 0.2 mils per year. The VA shall provide corrosion rate measurement equipment to measure corrosion rates by probes mounted in the four return condensate lines located in the boiler plant The vendor will establish a layer of magnetic iron oxide (black or dark gray in color) on all steel surfaces as a corrosion barrier. All chemicals shall be fed on a continuous basis directly to the boilers, DA Tank and Surge Tank. Dosage control shall be provided by means of adjustable devices. Timing of injection pumps (as on-off) to inject chemicals is not permitted. There shall be no scale or deposit formation as measured by visual inspections of the boilers internal watersides. Boiler water chemistry must be controlled to minimize blow down. The daily testing and Makeup Water usage will confirm the results. Total Hardness limit in the Makeup Water is set at 5 ppm maximum based on a sample taken from the online Water Softener. The 5 ppm is established as the Water Softener regeneration trigger point. This is to allow for variances in color vision perception due to the use of visual color test method. This limit shall not be increased. VA test frequency is normally once per day. Total Hardness of the Condensate Returns being received back to the boiler plant is desired to be zero ppm in each of the four return lines. A sample shall be taken from each of these four lines. The Contractor is responsible for establishing an upper limit of Total Hardness that will be the trigger point for the operators to dump these returns to waste until they return to within acceptable usage ranges. The four lines are; B-1, B-11/18, B-22/24 and B-52/53. VA test frequency is once per week on each line. PH of the Condensate Returns is suggested to be maintained in the range of 8.0 to 8.5 in each of the four return condensate lines located in the boiler plant. Volatile chemicals such as Amine must be fed into the boilers, instead of the steam header, in order to achieve even dispersal throughout the steam distribution systems. The use of coating / filming agents is not permitted. VA test frequency is once per day. Dissolved Iron in each of the four Condensate Return lines is suggested to be < 1.0 ppm. VA test frequency is once per week on each line Performance Requirements: (continued) Total Hardness limit in Surge (Return Condensate Storage) Tank located in the boiler plant is desired to be zero ppm. However due to the operating characteristics of the associated systems it is rarely zero and therefore a Phosphate treatment program is suggested. VA test frequency is once per day. NOTE; this tank is where the Makeup Water is added into the system. Conductivity in Surge (Return Condensate Storage) Tank is suggested to be < 100 us/cm. VA test frequency is once per day. Feed Water (water that is in the storage tank section of the Deaerator) Dissolved Oxygen shall be 7 parts per billion (ppb) maximum, with oxygen scavenger treatment temporarily suspended for a period of no less than 24 hours prior to test. If dissolved oxygen exceeds 12 ppb the contractor will provide chemical treatment recommendation to COR to control excess dissolved oxygen until such time as repairs are made by VA to restore the Deaerator to proper mechanical performance. These limits shall not be increased. VA test frequency is once per month. The Contractor will recommend boiler bottom blow frequencies and amounts of timing. However all steaming boilers WILL BE bottom blown on a daily basis by VA Operators for no less than 10 seconds per leg as it is accepted good engineering practice. The Contractor will recommend the Continuous Blow Down turn-on and turn-off set points. VA Operators will perform all controller calibrations and configurations. The Contractor shall provide a written fresh fill to treat dosage amount of chemicals required based on the gallons of water contained by the boiler at normal operating level to bring the boiler up to within the specified ranges when the boilers are freshly filled with water after being drained. Allowing the boiler chemical residuals to slowly build up to the specified chemical ranges is not permitted as the boilers would be either laid up or operating in an untreated condition for an undetermined amount of time. VA will inject the specified amount of chemicals for fresh filling during the filling process of the boilers. The Contractor shall provide written instructions stating the required amount of chemicals to be injected into the boilers for wet layup. The dosage of Sulfite shall be enough to raise the boiler residual to no less than 200 ppm. The PH of the boiler shall be no less than 10.0. If Phosphate is used it shall be no less than a 60 ppm residual. The method of wet layup used is the Steam Blanket. The boiler is maintained at normal water level and a steam pressure of 10 to 20 psig is maintained on the boiler Sulfite residual in boilers is suggested to be maintained within the range of 20-40 ppm. Sulfite will be injected in two locations. First into the Surge Tank due that the condensate transfer line is carbon steel and secondly into the DA Tank. The residuals to be carried in these two locations are to be determined by the Contractor with the end result being the range as stated above in the boiler. There are sampling capabilities to allow checking the residual for all three points. Only the boiler residual is required to be tested and reported. The other two test points may be utilized to establish the required injection pump settings. VA test frequency is once per day. Conductivity in boilers is suggested not to exceed 3000 us/cm for the current W&D boilers. The new boilers shall have their maximum Conductivity tolerance evaluated by chemical testing, and the maximum allowable limit shall be set to no less than 500 us/cm below the maximum tolerable limit to prevent carry over, foaming or priming. The use of anti-foaming agents is not permissible. Conductivity is specified because that is what the Continuous Blow Down Controller measures and is calibrated to Performance Requirements: (continued) PH in boilers shall be maintained in a range of 10.5 to 12.0. It also serves as a backup in the event there is no reagent available to perform the specified Alkalinity test as PH is indicative of Alkalinity. VA test frequency is once per day. Alkalinity in boilers shall be tested by performing a P&M Alkalinity test and calculating for O -Alkalinity. It is suggested to be maintained in the following ranges; P = 200 to 400 ppm, M = 300 to 700 ppm, O = 100 to 400 ppm. VA test frequency is once per day. Boiler Silica shall be tested for recording purposes. It shall be recorded in ppm. VA test frequency is once per week. Boiler polymer dispersant residual shall be maintained, as recommended by the selected water treatment vendor. Due to the operating characteristics of the various associated systems a Phosphate type treatment may be necessary for the boilers because of the high potential of hard water contamination at any time. If Phosphate is used a Phosphate test is required and the residual in the boilers is suggested to be 20 to 40 ppm. VA test frequency will be once per day if Phosphate is utilized.
