1.0 INTRODUCTION

1.1. Background

Due to Hanford mission needs, the systems are being updated to supply safe and reliable Sanitary Water (SW) for ongoing Hanford site cleanup activities. The existing storage tanks, 283EA and 283WA, serve the SW system. The SW system produces Potable Water (PW).

1.1.1. Existing Potable Water Storage Tanks

Project B-604, Water System Upgrades was initiated in the mid-1990’s to provide upgrades to Hanford’s Export Water (EW), Raw Water (RW) and SW systems. The purpose of the upgrades was to meet the U.S. Department of Energy’s (DOE) requirement for two reliable, independent sources of water available for fire suppression for the Central Plateau in 200 East (200E) and 200 West (200W) areas. The project included the construction of two PW storage tanks serving the RW and SW systems, each with a nominal storage capacity of 1.16 million gallons (MG) and a design life of 20 years. The tanks, 283EA and 283WA, were constructed of welded carbon steel and are located in the 200E and 200W areas of the Hanford Site, respectively.

The tank interiors have documented inspections for the years of 2007, 2013 and 2017. The 2007 inspection assigned a rust rating to the various interior tank surfaces based on American Society for Testing and Materials (ASTM) D610, Standard Practice for Evaluating Degree of Rusting on Painted Steel Surfaces. Most surfaces had a rating of 8 or better, which corresponds to a maximum surface rust area of 0.1%. Exceptions included the anti-vortex plate, graded 5, or up to 3% of the total surface area and the roof vent with a grade of 7 (up to 0.3%). The 2013 inspection stated that the tanks exhibited staining, bubble formation, and cracks in the interior coating. Corrosion above the high-water mark was more pronounced with the roof showing widespread corrosion and paint loss. The 2017 inspection report noted heavy rusting at the high-water mark and above, including heavy deterioration of the roof support I-beam and heavy corrosion in the hatch area. Areas of rust and paint bubbling were observed below the high-water mark.

1.1.2. Existing Sanitary Water Distribution Pumping

The two SW pump house facilities, 283E and 283W, are rapid gravity, dual media filtration water treatment facilities constructed in 1944. Only 283W remains operational; however, each facility contains two functioning clear wells, which are approximately 200,000 gallons each, and both facilities contain active SW distribution pumps. The existing SW distribution pumps located in pump house buildings 283E in 200E, and 283W in 200W will be replaced with new pumps as part of the upgrades under Project L-849 in existing pump house 282EC and Project L-850 in existing pump house 282WC.

The four existing SW distribution pumps in 283W and in 283E have a combined pumping capacity of 3,400 Gallons per Minute (GPM) at 110 pounds per square inch



Page 8 of 35

(PSI). Three of the four SW pumps in 283E have been replaced since 2015. One of four pumps in 283W has been replaced since 2015.

1.2. Scope, Mission and Justification

Two replacement PW storage tanks will be designed and constructed. The L-849 tank will be located near 282E RW Reservoir and the L-850 tank will be located near 282W RW Reservoir. The total volume of the tanks will be increased per the quantities provided within HNF-CALC-64157, Basis of Tank Size with each tank serving as a redundant supply to the SW system.

This Functional Requirements and Design Criteria (FRDC) document addresses both Projects L-849 and L-850, because it is assumed the tanks will differ only in the following ways:

• A boost chlorination injection system shall be designed and installed as part of the ProjectL-849 work scope.

• Project L-850 will be serve a dual function as (1) water storage and (2) the contact timechamber for proposed new Central Plateau Water Treatment Facility (CPWTF) the tankwill be required to have internal baffling.

1.2.1. Project L-849

Project L-849 will design and construct a new PW storage tank (283EG) with a minimum total volume of 1.5 MG usable capacity based on HNF-CALC-64157, Basis of Tank Size, to replace the existing PW storage tank, 283EA in 200E. The storage volume is based on worst-case fire suppression water demand of 3,000 GPM and a peak hotel/domestic PW demand of 2,220 GPM.

Project L-849 will remove existing RW booster pumps and associated electrical, and add new SW pumps and associated electrical for pressurizing the SW grid, as well as a tank recirculation pump. The new pumps shall be installed in the existing 282EC pump house and will be designed to meet projected fire suppression demand of 3,000 gpm and peak domestic demand of 2,220 gpm at 110 psi. Standby power is required and the existing 282ED generator shall be evaluated for sufficient capacity to support electrical load demands for Project L-849.

The new PW storage tank 283EG will require freeze protection, booster chlorination system, tank mixing, and piping reconfigurations to allow for the new SW distribution pumps and existing fire pump inside 282EC to draw from the new tank 283EG. No internal baffling is required for the L-849 tank since it includes a tank mixing system.

The project shall be in accordance with Washington Administrative Code (WAC) 246-290, American Water Works Association (AWWA) requirements, and applicable sections of the latest Washington State Department of Health (WDOH), Water System Design Manual.



Page 9 of 35

The existing PW storage tank 283EA shall be decommissioned, demolished and removed leaving only the concrete foundation following final commissioning and acceptance of the WDOH Construction Completion Report for Project L-849.

1.2.2. Project L-850

Project L-850 will design and construct a new PW storage tank (283WG) with a minimum total volume of 1.5 MG usable capacity based on HNF-CALC-64157, Basis of Tank Size, 283WG, to replace the existing PW storage tank, 283WA in 200W. This new tank will function as both storage and the contact time chamber for CPWTF. The storage volume is based on worst-case fire suppression water demand of 3,000 GPM and a peak hotel/domestic PW demand of 2,220 GPM.

Project L-850 will remove existing RW booster pumps and associated electrical, and adds new SW pumps and associated electrical for pressurizing the SW grid as well as a tank recirculation pump. The new pumps shall be installed in the existing 282WC pump house and will be designed to meet projected fire suppression demand of 3,000 gpm and peak domestic demand of 2,220 gpm at 110 psi. Standby power is required and the existing 282WD generator shall be evaluated for sufficient capacity to support electrical load demands for Project L-850.

The new tank will require freeze protection and piping reconfigurations to allow for the new SW distribution pumps and existing fire pump in 282WC to draw from the new tank 283WG, as well as bypass the 283WG tank in the event of a loss of tank accident.

The project shall meet WAC 246-290, AWWA requirements, and applicable sections of the latest Washington State Department of Health, Water System Design Manual.

As part of the water treatment process that will involves the L-850 tank and the CPWTF (Project L-897), this tank is required to be part of the WDOH Tracer Study for overall WDOH approval and use of each facility. The Tracer Study will be performed by Project L-897.

The existing tank 283WA shall be decommissioned, demolished, and removed leaving only the concrete foundation following final commissioning and acceptance of the WDOH Construction Completion Report for Project L-850.

1.3. Site Location

Project L-849 will be located near the existing tank, 283EA, in 200E (see Figure 1). Project L-850 will be located in close proximity to the existing tank, 283WA, in the 200W (seeFigure 2). Exact locations will be determined upon completion of the selection of the type ofstorage tank system, soils analysis, and review of existing site utilities and infrastructure inand around the qualifying sites. The new SW distribution pumps will be installed in existingpump houses 282EC and 282WC which presently house inactive RW booster pumps and anactive fire pump.

3.0 PROJECT INPUTS

3.1. Description of Existing System(s)

The existing 1.16 MG storage tank 283WA receives PW from the existing 283W Water Treatment Facility (WTF). The PW storage in the tank serves as the source water for the 200W fire pump located in 282WC, as well as 200W PW storage. The tank also serves as the source of fire protection water for the RW distribution system in 200W. Project L-894, Raw Water Cross Connection Isolation 200E/W will sever all connections between the SW and RW systems.

The existing 1.16 MG storage tank 283EA also receives water from the existing 283W WTF. The PW storage in the tank serves as the source water for the 200E fire pump located in 282EC. The tank also serves as the source of fire protection water for the RW distribution system in 200E.

SW distribution pumps located in 283E and 283W fill the storage tanks. There are four pumps in each facility, two constant speed and two variable speed. All have 100 horsepower (HP) and have a combined pumping capacity of 3,400 GPM at 254 ft. of head. Pump houses 282EC and 282WC each contain a 110 GPM recirculation pump for recirculation in addition to the fire pumps which provide suction at the tank bottoms. The fire pump in 282EC is capable of pumping 4,500 GPM at 254 ft. (110 PSI) of head. The fire pump in 282WC is capable of pumping 4,000 GPM at 254 ft. of head.

A detailed description of the existing 283EA and 283WA storage tanks is available in HNF-59688, Sanitary Water System Design Description (SDD) Section 4.1.1.3. Additionally, a detailed description of the distribution and fire pumps can be found in Section 4.1.1.4.

3.2. Physical and System Interfaces

3.2.1. Interrelationship with Other Processes

The new L-849 and L-850 storage tanks are critical components to the Central Plateau PW distribution system and fire suppression water storage. The L-850 tank shall also fulfill the required disinfectant contact time (CT) for the new CPWTF per WAC-246-290, Group A Public Water Supplies. This new CPWTF is designed as a hollow fiber membrane microfiltration plant. Baffling inside the L-850 tank will be used to achieve adequate chlorine disinfection CT.

Connections to the 282E and 282W RW reservoirs will be required to dispose of the water required for filling, checking the new storage tanks for leaks and flushing of the storage tanks and associated piping installed under the three projects (L-849, L-850, and L-897).



Page 18 of 35

3.2.2. Interrelationship with Other Facilities

The new PW storage tanks constructed within Projects L-849 and L-850 will initially receive PW from the existing 283W WTF. Once the new CPWTF is operational, the CPWTF will be the sole source of PW for the storage tanks. The new tank drain and overflow lines will be routed to the respective 282E/282W RW Reservoirs. The new distribution pumps will be installed in 282EC and 282WC in place of inactive RW booster pumps.

3.2.3. Interrelationship with Other Systems

The new storage tanks will interface with the following systems:

• The filtrate to the L-850 200W tank will be supplied directly from the newCPWTF under Project L-897.

• The PW to the L-849 200E tank will be supplied by the new SW distributionpumps in 282WC.

o To further describe the supply from 282WC to 200E; the current systemconfiguration, SW is supplied from the 200W distribution pumps to the200E area grid connections near the existing 283EA tank through the sitecross-tie piping system. The site cross-tie piping consists of 8-inch and12-inch lines which do not consist of a single continuous run. The 8-inchsection begins south of 282W and routes to Radiological Site Services(RSS) supply lines. From the RSS, the grid cross-tie branches off to a 12-inch section of line past the fire station (Station 92) and continues east tothe 282E and 282EA grid supply connections.

• Project L-849 and L-850 will maintain RW service to the 282EC and 282WCbuilding fire suppression systems.

• Projects L-849 and L-850 will integrate instrumentation and controls for suchthings as pumps, electrical equipment, sensors, etc., these instrumentation andcontrols shall communicate/interface from their local PLC to the new CPWTF’sICS. The current PLCs monitor signals from the fire pump and the generator.The design shall convert these existing signals to report the new PLC/HMI controlsystem. These PLCs will connect to the WLAN network via network architectureavailable in 282EC and 282WC. Both newly installed PLC cabinets in 282EC and282WC will have network switches in them that will be attached to the WLANnetwork, allowing operators remote monitoring capabilities.

• Normal Electrical and Standby Power sources are currently available in the282EC and 282WC pump houses.

• The new SW distribution pumps shall be located in existing pump houses 282WCand 282EC.



Page 19 of 35

• The new systems will interface directly with the Hanford 200E/W SW firesuppression systems.

3.2.4. Interrelationship with Other Projects

Project L-897, Central Plateau Water Treatment Facility requires the completion of Project L-850 before it can be tested and operated. The storage tank provided by L-850 will serve as the clear well for the CPWTF and its distribution pumps will provide the motive force to pump the filtrate into the SW distribution system. Project L-897 will perform the Tracer Study for both Projects L-897 and L-850, which is required to be submitted for approval by the WDOH.

Project L-849 is indirectly related to this Project. Project L-849’s design is not required to be completed prior to turnover of the CPWTF.

Project L-894, Raw Water Cross Connection Isolation 200E/W eliminates all rigid connections between RW, EW and SW, largely replacing them with air gaps per WAC 246-290-490, Cross-connection Control, and includes installing a new 30-inch cross-site tie between 200E and 200W in the RW system to replace lost redundancy. Project L-894 will eliminate SW backup for RW fire suppression by removing the SW to RW cross-tie connections (located within or adjacent to 282EC and 282WC as Reduced Pressure Backflow Assemblies (RPBAs) and installing new isolation valves within the SW system so that no connection between SW and RW exists. The existing SW fire pumps in 282EC and 282WC will continue to provide additional pumping capacity for SW fire suppression requirements/demands.

3.2.5. Interferences with Other Structures and Infrastructure

3.2.5.1. Railroads

Due to the congestion of existing underground utilities and the need to route the new SW piping around existing Tanks 283EA and 283WA without causing any problems with the tank’s stability, the permanent removal of railroad lines is allowed for routing of any required tanks or piping configurations/designed locations. Rail and associated materials will need to be removed and managed in accordance with the requirements of WAC 173-303-071(3)(g)(ii), Excluded Categories of Waste.

3.2.5.2. Piping

Project L-849 - Due to congestion of existing underground utilities around tank 283EA and nearby structures, abandoned equipment and associated piping/electrical may be able to be demolished/removed with MSA approval.

• Minimize the time requirements for maintenance

• Minimize the equipment and tools required for maintenance

• Minimize maintenance requiring special skills

• General accessibility to perform inspections and maintenance

• Design shall preclude the introduction of hazardous conditions duringpreventative maintenance procedures (e.g. activities requiring lockout/tagout)

• Critical systems shall be capable of undergoing maintenance without theinterruption of critical services

• Notification of loss of operational redundancy shall be provided immediately.

The A/E will identify and prepare an owner/operator maintenance schedule/manual for the selected exterior and interior materials and equipment specified in the final design construction documents. A Pre-Startup Pre-Operational Test Plan will be produced by the A/E that will ensure critical components are installed and operate correctly.



Page 28 of 35

The design shall limit the creation of new maintenance requirements. Recommended changes to the SW system maintenance shall be identified and documented in the final design. Maintenance manuals for all new equipment shall be provided.

As part of meeting the requirements of MSC-PRO-MN-56346, Predictive Maintenance Program, and MSC-PRO-WC-19304, Periodic Maintenance Process, pumps and motors will be required to have design features that allow the installation of long-term bearing vibration and bearing housing temperature monitoring equipment.

This equipment’s intended use is to monitor, measure, and trend bearing vibration and bearing housing temperature for inboard and outboard bearings of designated pumps and motors. The data gathered shall be compared to operational limits established by the equipment vendors and/or by a Reliability Engineer with a vibration analyst certification. This bearing vibration and bearing housing temperature equipment is to be installed prior to completion of the project turnover to Operations.

Condition monitoring equipment shall be coordinated with a commercially available data acquisition system that will interpret the data and activate alarms when operational limits are exceeded, communicate with analysis software approved by MSA’s Cyber Security Program, and allow the data to be accessed and downloaded from local and remote locations. This type of system is commonly known as an online condition monitoring system. This condition monitoring system shall be compatible with the system integration project that spans W&SU. This data shall be, but is not limited to, vibration readings in velocity Root Mean Square (RMS), temperature readings in Fahrenheit, live (or most recent) vibration levels in velocity RMS and acceleration RMS, Time Wave Form data, and Frequency Spectra (Fast Fourier Transform) data. This will allow specified personnel to be notified of a vibration or bearing temperature alarm, allow the vibration analyst to trend data over time, and perform in-depth analysis. The necessary software for vibration analysis needs to be used in conjunction with a shaft speed sensor (tachometer) for proper analysis.

Triaxial and biaxial vibration sensors, with integrated temperature sensors, are to be used for monitoring designated motor and pump bearings. These sensors must be 100mV/g (millivolt per gravitational constant) piezoelectric accelerometers with a maximum frequency response range of at least 10kHz (10,000 Hertz). Triaxial sensors shall be used for outboard bearings (non-drive end) and biaxial sensors shall be used for inboard bearings (drive end).

The MSA Cyber Security ensures that all cyber assets within the Hanford Accreditation Boundary are protected from threats throughout the complete project life. W&SU shall collaborate with MSA Cyber Security to demonstrate any data or cyber assets used in support of predictive maintenance are compliant with Hanford’s National Institute of Standards and Technology (NIST) compliant Risk Management Framework.

Upon turnover of the new tanks, the existing 283EA and 283WA tanks shall be decommissioned, demolished and removed with the exception of the foundations following final commissioning and WDOH approval of Projects L-850 and L-897.

All piping penetrations in the concrete slab shall be filled with grout and all protrusions removed flush with the slab.

4.5. Equipment Instrumentation, Controls and Automation

For Projects L-849 and L-850 the tank water level shall be monitored by level transmitters that continuously monitor the SW tank levels and send a signal to the PLC.

The SW pumps shall be controlled by the local PLC to maintain a target manifold pressure on the SW grid. At minimum SW demand, one pump shall operate at minimum speed and excess water is recirculated through a pressure relief valve. As demand increases, the recirculation is stopped and the pump will operate at a speed sufficient to maintain target pressure. As the demand further increases and the pump approaches maximum speed an additional pump shall be started and the speeds of both pumps matched and controlled to maintain target pressure. As demand increases additional pumps shall be started and speed matched to maintain target pressure. As demand decreases, pumps shall be slowed and shut down in the reverse order. A lead pump rotation scheme shall be used to distribute the elapsed operating time of all pumps evenly. There shall also be a provision for the Operator to disable or manually operate any pump from the HMI. Pump capacity shall be such that the SW system peak hourly demand (PHD), as identified in HNF-5828 Section 3.1, can be met with one pump out of service.

The water heater in the recirculation line shall have a thermostat to activate the water heater when the water temperature is below its setpoint. The PLC shall monitor the water temperature at the heater and shall have the ability, through Operator command on the HMI, to also activate the water heater.

The local PLC shall transmit the tank level, pump motor status, pump flow rates, water temperature and other data of interest back to the CPWTF (283WR). An Operator at the new CPWTF shall have the same functionality on that HMI as at the individual pump houses with user-configurable alarms. The current PLCs monitor signals from the fire pump and the generator. The design shall convert these existing signals to report the new PLC/HMI control system.



Page 30 of 35

A new PLC shall be located in each pump house and shall replace the PLC panels that were installed under project L-778 (282E Plateau Water PLC and 282W Plateau Water PLC). Unused PLC equipment will be removed during tank demolition phase.

Projects L-849 and L-850 shall include Hansford/Uptime Solutions (or W&SU Reliability Engineering approved equal) to provide vibration and temperature monitoring, trending and data analysis for the pumps and motors. The design shall include the necessary features and components that provide the ability to connect the vibration and temperature monitoring signals from the pumps and motors to the PLC for remote monitoring and alarm capabilities.

4.6. Operational Requirements

The water storage system shall include sufficient redundancy to be operationally effective 24-hours a day, 365-days a year. Pump capacity shall be such that system demand may be metwith one pump out of service.
