D. Annual service tasks:

(1) Be present during boiler and chiller inspections to observe interior of the vessels.

(2) Document all equipment inspections with external photographs as well as photos of equipment internals (i.e. boroscope inspections). It is expected that if the PVAHCS provides 2 week notice, a boroscope will be available for inspection and a formal report with photos will be provided subsequent to the inspection.

(3) Conduct water softener elution studies and Rexnord dissolved oxygen tests. The vendor shall provide a Dissolved Oxygen sampling test kit with ampoules for 0-100 ppb.

E. Training service requirements:

(1) In order to ensure that plant personnel are adequately trained, the vendor shall conduct a comprehensive evaluation of each operator involved in testing and training to ensure the program is implemented properly. Training shall be conducted quarterly as a review or earlier if there are any Shift-to-shift discrepancies during the first 90 days of the agreement on all personnel present in the plant at the time of the visit.

(2) Vendor shall develop a comprehensive operator’s manual for each of the systems to be treated and this manual shall be used in the training program.

(3) Vendor shall have a checklist for certification that each operator trained is competent in testing, adjustments, water chemistry fundamentals, etc. The check list shall be reviewed in a practical “test” with the operators by a different member of the vendor’s organization to certify/qualify each operator’s competency. Each operator shall have a dated checklist to be maintained by the vendor.

F. Chemical requirements:

(1) All chemical products must be approved by the Food and Drug Administration and there shall be no objection by that agency to the use of the chemicals for the treating of boiler water where steam contacts food or food products. Chemicals must be delivered to the VA Utility Plant and placed in the vendor provided portable feed containers by the vendor. Plant personnel shall not handle the chemicals. MSDS shall be provided on all chemical products and shall be attached on each bulk tank.

(2) Cooling tower compounds will be liquid form and will be injected into a common header or the sump. PVAHCS owns chemical injection pumps and chemical tubing, but the vendor is to both repair rand provide pump repair kits (liquid ends) and additional chemical tubing to maintain the pumps if appropriate. The vendor is expected to provide proper troubleshooting and due diligence before recommending any chemical pump or other equipment replacement. PVAHCS will purchase replacement equipment after proper evaluation of the failed equipment has been performed and must be approved by plant management.

(3) Condenser Water Scale & Corrosion Inhibitor: The inhibitor shall be a multi-functional blend of the following:

a. Phosphoric Acid (steel corrosion inhibitor)

b. Benzotriazole/Tolyltriazole [BZT/TT] (copper corrosion inhib.)

c. High Stress Polymer (dispersant & stabilizer)

d. Organic Phosphate that does not revert to orthophosphate (corrosion & scale Inhibitor)

e. Inert Chemical Tracer (testing & monitoring)

(4) Condenser Water Oxidizing Biocide (12.5% bleach): Because PVAHCS uses pH adjustment, the oxidizing biocide will be bleach. The vendor must supply bleach through bulk fills through only closed connections. Under no circumstances may bleach be pumped or poured from a drum into the base tank. The base tank may be owned/supplied by a commodity chemical supplier, but the vendor shall be responsible for the chemical fills and cost of the material.

(5) Condenser Water Non-Oxidizing Biocide: Due to its acute health hazard, Isothiazolin (a sensitizer) shall not be used in the condenser water system. 50% Glutaraldehyde is the non-oxidizing biocide of choice, but we understand that there may be certain instances where other non-oxidizers may be used to supplement the condenser or evaporator water treatment’s biocide program. Other non-oxidizing biocides shall be approved by PVAHCS as needed.

(6) Condenser water pH Control (93% sulfuric acid): The vendor must supply bleach through bulk fills through only closed connections. Under no circumstances may acid be pumped or poured from a drum into the base tank. The base tank may be owned/supplied by a commodity chemical supplier, but the vendor shall be responsible for the chemical fills and cost of the material.

(7) Closed Loop Corrosion Inhibitor: Due to past microbio excursions in the main chiller plant’s chilled loop, the decision has been made to move forward with non-nitrite, non-molybdate closed loop corrosion inhibitors. PVAHCS does not expect the vendor to re-charge the loop initially, but is required to test both the old (nitrite) and new inhibitor chemistry until the nitrite is <100 ppm.

(8) The closed loop inhibitor shall contain:

a. An organic phosphonate that does not revert to orthophosphate (steel corrosion inhibitor)

b. A high stress polymer (dispersion & stabilization)

c. Azole (copper corrosion inhibition)

d. Inert tracer (troubleshooting and leak detection) Note: Silicate corrosion inhibitors are not acceptable because they do not offer cathodic protection. No heavy metal corrosion inhibitors (ex. molybdate) shall be used.

(9) Closed Loop Biocide: Due to its acute health hazard, Isothiazolin (a sensitizer) shall not be used unless plant training is conducted annually and signage exceeding the “legal requirements” of OSHA/FIFRA requirements is hung to identify to the hazard clearly to even casual visitors to the plant. The acute sensitizer shall be handled with extreme care and all plant personnel shall be trained to understand the hazard.

(10) The PVAHCS prefers chlorine dioxide (ClO2) as the closed chilled and thermal storage biocide of choice. The main chilled loop currently contains nitrite, so chlorine dioxide shall not be used in the main chilled loop until the nitrite level is <100 ppm. The thermal storage system will not be on nitrite and ClO2 can be used immediately.

(11) Isothiazolin and Glutaraldehyde are the non-oxidizing biocides of choice, but the ability to provide ClO2 dosing is heavily weighted and preferred.

(12) Closed loop biocides shall be dosed a minimum of four times per year on both the Main Chilled Loop and the Thermal Storage System.

(13) Boiler Internal Treatment (all polymer): The boiler internal treatment shall be an all-polymer program. Phosphate, polyphosphate, organophosphate, chelant, phosphate/chelant blended programs shall not be proposed and are not an acceptable boiler internal treatment chemistry.

(14) Boiler Oxygen Scavenger (sulfite): The oxygen scavenger shall be catalyzed sulfite in liquid form. Powdered sulfite shall not be proposed.

(15) Boiler Condensate Treatment (amine): The amine shall be a blend of three different volatility amines to ensure protection of the various legs of the condensate return system. The amine shall be a blend of:

a. Cyclohexylamine

b. Diethylaminoethanol

c. Morpholine

(16) Boiler water treatment will be of the liquid form. PVAHCS owns chemical injection pumps and chemical tubing, but the vendor is to both repair rand provide pump repair kits (liquid ends) and additional chemical tubing to maintain the pumps if appropriate. The vendor is expected to provide proper troubleshooting and due diligence before recommending any chemical pump or other equipment replacement. PVAHCS will purchase replacement equipment after proper evaluation of the failed equipment has been performed and must be approved by plant management.

(17) Volatile Oxygen Scavengers (VOS) will be fed similar to the amine, recommendations from the Contractor and determination by Plant Supervisor as to the best way to inject.

G. Water chemistry operational parameters:

(1) Boiler Water:

(2) Feedwater:

e. Chloride condensate return percentage calculation (monthly, FW/Soft chlorides)

(3) Condensate Return:

(4) Condenser water:

e. Scale & corrosion inhibitor control expected +/- 5% variance from target (Ex. Target = 2.0 ppm Moly; Control range = 1.9 – 2.1 ppm)

(5) Closed loop cooling and heating hot water:

H. Chemical storage, handling and delivery requirements:

We are concerned with chemical storage, drum handling and disposal at our site. To reduce our risk associated with drum handling, we prefer all products delivered to the point of feed. Mild steel drums of any size >5 gallon pails are not acceptable. 5-gallon pails are not acceptable for biocides. To eliminate chemical handling by site personnel, all products must be capable of being fed neat (without dilution or contact) by our operators or your service professionals (no manual dilution onsite will be accepted). In order to minimize our liability in this regard, we require the following regarding chemical delivery and storage.

(1) The vendor will provide a comprehensive delivery program that removes the burden of chemical deliveries and handling. This program utilizes either plastic or stainless steel mini-bulk tanks as the point of use container.

(2) The point of use container must be more than a double walled container and shall serve as appropriate spill containment as well. The spill containment must be able to contain a minimum of 150% of the volume of the base tank within.

(3) All storage tanks (except bleach and acid) shall have a fixed bottom drain/suction capabilities to ensure positive, flooded suction for chemical pumping and injection as well as to allow complete emptying of the vessel without turning it on its side. Vendor will retain ownership of the chemical storage tanks.

(4) Chemical transport equipment must comply with DOT requirements for transporting hazardous materials. This includes subcontractor’s acid and bleach deliveries.

(5) Deliveries must be made by chemical handlers who are:

a. Certified in HAZMAT compliance

b. Equipped with PPE on-site for delivery and transfer of chemical.

c. Equipped with items required to handle spoils and any unexpected incidents.

(6) No empty or full chemical transport equipment is to be stored on-site.

(7) If chemical transfers into the base tank are to be made by either hand-filling (pouring 5 gallon pails into base tank) or via unsealed chemical transfer pumps, a formal written base tank filling safety protocol must be supplied with this proposal for the PVAHCS to evaluate this delivery method for consideration. If this is the vendor’s only option for bulk tank deliveries, please disclose this information for proper evaluation purposes. Vendors will not be disqualified for taking exceptions so long as there is proper justification attached.

(8) Chemical inventory level sensors must be installed to record accurate inventory within +/- 0.5 gallons without exposing personnel to an open drum inventory inspection.

(9) Base tanks shall have a shelf for each pump within the area of the containment basin to catch potential chemical pump leaks. Each pump shall be permanently mounted to the shelf without penetrating the base tank or containment basin.

(10) Base tanks shall be sided appropriately and shall not run below 15% full at any time to avoid interruption to the water treatment program.

(11) Closed/sealed chemical transporters are highly recommended. If used, 5, 15, 30 & 55 gallon drums shall be removed from the site after triple rinsing.

(12) Base tanks and any drum brought onsite must both be labeled per OSHA guidelines. All biocides must adhere to the EPA’s FIFRA requirements and labeling practices.

(13) The PVAHCS is satisfied with the bleach and acid delivery and installation. We recommend the acid and bleach be delivered in a manner similar to the current program. The vendor will be responsible for ordering and supplying both 12.5% sodium hypochlorite and 93% sulfuric acid within the contract. Absolutely no bleach or acid drums or transporters will be left onsite or shipped to the site without immediate transfer into the containment basin by a certified HAZMAT material handler. Fills must occur only through a closed connection (ex. Cam lock fitting and permanently fixed hose)

I. Laboratory analysis requirements: Contractor shall have an in-house laboratory or access to a contract laboratory capable of assisting in solving challenges that arise which may cause loss of efficiency or equipment damage. When samples are taken for resolution of problem or routine analyses (differential microbio analysis, coupons, etc.), the results must be supplied and a written report delivered to the PVAHCS within three weeks. Please provide the name and address of your in-house laboratory.

J. OPTIONAL SERVICES: OVER & ABOVE REPAIR Upon request, the vendor will provide a quote as-needed with pricing for any additional chemistry, equipment or services needed to:

(1) Address unexpected emergencies

(2) Recharge any system

(3) Perform additional laboratory testing outside of this scope

(4) Perform special studies not outlined in this scope

3. Cooling Tower Cleanings with Disinfection:

A. Health and Safety: All of the vendor's service technicians must be respirator fit-tested annually. They also must be formally trained on all aspects of Fall Prevention, Confined Space Entry, and Personal Protective Equipment. Safety is a concern for the PVAHCS and we expect the vendor to be able to supply documentation of training immediately if requested.

B. OSHA Compliance: We expect the cleaning and disinfection to follow Section III, Chapter 7 of the OSHA Technical Manual, Legionnaire’s Disease. This recommendation is critical in complying with the OSHA Title 29 USC Section 654, “Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”. We expect that our vendor follows the cleaning and disinfection guidelines prescribed to reduce the risk of Legionnaire’s Disease, and provide a safer work environment.

C. Although the OSHA recommendation states “Cooling towers should be cleaned and disinfected at least twice a year”, we are requesting QUARTERLY cleanings of each of the cooling towers (4 at central plant and 4 at packaged central plant).

D. Documentation: All aspects of the Cleaning and Disinfection project are to be documented for our records. This record is to show the PVAHCS’ diligence and compliance in following the guidelines and recommendations to reduce the risk of waterborne pathogens in your facility.

E. Frequency: Cleanings and disinfections shall be scheduled and performed quarterly.

F. Procedure and PPE: During the cleaning procedure, all employees shall wear all required personal protective equipment, including Tivek suits, hardhats, gloves, rubber boots, and respirators with appropriate cartridges. During procedures that require fall prevention measures, harnesses and appropriate equipment shall be used. For areas that are considered confined space, whether permit-required or non-permit required, the Cleaning Supervisor shall complete a Confined Space Entry form.

(1) Pre-Disinfecting: This step shall be done before the mechanical cleaning of the tower as a precursor to the actual cleaning process, and will be facilitated by the vendor’s water treatment representative.

If possible, all cooling tower fans will be OFF, and all recirculation pumps for these systems will be ON. Vendor will initiate a thorough disinfecting of the tower by adding elevated levels of an oxidizing biocide to elevate the free chlorine residual, per OSHA and TS425G recommendations. A biodispersant will also be added to the system to increase the performance of the oxidizing biocide. This procedure is done to break up and remove the organics, bacteria, and slime that are trapped in the fill as well as for personal health and safety reasons of the vendor’s employees entering the cooling tower, as well as patients and employees of the PVAHCS.

(2) Manual Cleaning of Cooling Tower: Isolate and drain each cell for cleaning. Our engineering staff will assist the vendor in tower isolation and proper lockout tag-out.

The vendor will utilize high-pressure washers to wash the entire internal and external areas, (as available) to remove as much of the dirt, bacteria, and debris as possible and have it collect in the actual tower sump. Once the majority of the dirt and debris has collected in the tower sump, the vendor shall clean the entire sump and remove the existing debris for disposal.

(3) Final Disinfecting and Passivation of Complete System: After each tower cell is completely refilled, the vendor’s water treatment representative will again disinfect the system, per step 1. Once completed, the water treatment program can be resumed and re-passivation of the metal surfaces initiated (because using an oxidizing biocide increases the potential for flash corrosion).

(4) Documentation and Certification: The vendor shall provide documentation and certification of professional cleaning and disinfecting per The OSHA Technical Manual. The documentation will include the pre-cleaning inspection report, the documentation of the procedures, as well as a completion certificate for your records.

G. PVAHCS will provide the following to facilitate the cleanings:

(1) Isolate the cooling tower (cells) and/ or turn off the chillers before cleaning if applicable.

(2) Remove and clean any system strainers.

(3) Provide a 25 amp, 110V, 60 Hz single-phase electrical supply near to the working area.

(4) Access to water and electricity for any cleaning equipment.

(5) Free, safe and unrestricted access to the cooling tower(s) and associated pipe work for the duration of the cleaning.

(6) A responsible engineering contact that is fully conversant with the system and its operation.

(7) Parking and off loading facilities near the cooling towers to be cleaned.

(8) PVAHCS’s Lock-out/Tag-out procedures are addressed, and responsible operators will be available to facilitate all staff and onsite contractors to follow the procedures.

(9) Updates on any operational changes or requirements of the facility that may affect the vendor’s ability to conduct cleaning and disinfections in a safe and effective manner.

(10) Access to dumpsters for disposal of debris
