For additional information, please see the revised and new supplementary project documents as referenced below. General Comments PG&E personnel must contact this office to discuss the possibility of this work being interrupted from the COVID-19 pandemic. PG&E must explain if delays or the absence of key workers (such as contractors, drillers, geologists, etc.) could leave the project in a compromised position and, if so, what contingencies will be in place to prevent this from happening. PG&E must also provide a written description of these contingencies prior to start of construction. We may rescind the authorization to start construction if PG&E cannot adequately address these issues. to start construction if PG&E cannot adequately address these issues. Response: Refer to PG&E’s COVID-19 Contingency Plan memorandum, titled Grizzly Forebay Dam LLO Modification Project (FERC No. 619), PG&E Response to COVID-19 Contingencies, prepared by PG&E and dated June 5, 2020. Specific Comments Project Description. It appears that wet dredging will occur in conjunction with the low- level outlet modification project near the upstream face of the dam. Please provide the extent and estimated quantity of material to be dredged. A similar request for additional information related to dredging work was contained in the Commission’s May 7, 2020 order authorizing temporary stream and reservoir variances. You may fulfill this request by concurrently filing this information with the Commission Secretary and the San Francisco Regional Office. Dredging activities should not begin until you have obtained all the necessary permits and received authorization from this office to commence dredging activities. Response: PG&E will provide for FERC SFRO records a copy of its Project Description (PD) for the Grizzly Subsurface Debris Removal Project, which is scheduled to occur concurrently with the LLO 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Enclosure 1 Grizzly Forebay Dam Low-Level Outlet Modification Project Responses to Comments from FERC dated May 8, 2020 Page 2 modification project. A copy of the PD will also be submitted to the Commission Secretary. To assist with FERC’s review, relevant information from the project description is summarized below. During a 2013 dive inspection of the low-level outlet and intake tower, large woody debris and a substantial amount of organic material was discovered at the base of the intake, at the base of the dam, and near the LLO. Debris and sediment that is being drawn into the intake at the forebay is contributing to the deterioration of equipment within the powerhouse and could potentially impact the reliability of the LLO operation. To prevent additional damage to equipment and reduce the risk of interrupted flows through the LLO, PG&E intends to remove approximately 2,800 cubic yards of debris from the reservoir adjacent to the LLO and the intake structure. Mobilization of staff and equipment is scheduled to begin in late June 2020, with work anticipated to begin by mid-July. A barge-mounted crane with a clam shell attachment will be the primary equipment used to excavate the material from the reservoir. The material will be placed on material barges for transporting to an offload facility at the shoreline. Material will then be transferred from the barges to trucks, which will haul the material to a PG&E disposal area. The contractor will utilize divers to verify the limits of excavation during work by performing dives at regular intervals throughout the project. The divers will also be able to identify underwater obstacles that may impact the clam shell operation and have the underwater capability to remove any of these obstacles. To contain the potential increased turbidity due to underwater excavation within the reservoir, a turbidity curtain will be utilized upstream of the work area. The turbidity curtain will be anchored at the topside using suitable timber locations and/or natural boulders at the shorelines. The underwater locations will be anchored using concrete blocks at regular intervals along the bottom seal. Other weighted devices will be placed in areas where concrete blocks cannot be placed due to underwater obstacles or areas with unique terrain features. The intake for the LLO is located within the debris removal area so it will need to be closed during excavation activities to eliminate release of turbid water. For this reason, a temporary bypass pumping system will be implemented upstream of the turbidity curtain to provide the minimum instream flow release (IFR) over the spillway. As described in the PD, PG&E has determined that discretionary permits or authorization from resource agencies are not applicable for the following reasons: 1. Project activity and impacts are not a regulated activity under the Clean Water Act Section 404 and will therefore do not require US Army Corps of Engineers and Regional Water Quality Control Board permits (under Clean Water Act Sections 404 and 401 respectively). 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Enclosure 1 Grizzly Forebay Dam Low-Level Outlet Modification Project Responses to Comments from FERC dated May 8, 2020 Page 3 USACOE has reviewed the activity and provided written confirmation that no permit is required for the activity (email dated May 31, 2019) and subsequently issued a No Permit Required letter (SPK-2019-00361). Central Valley Regional Water Quality Control Board was provided the same project information as the USACOE (email dated June 7, 2019) including the USACOE communication as notification that the activity is not subject to a CWA 404 permit, therefore no CWA 401 Certification is expected. 2. Project activities will entail ground disturbance of over one acre in area, therefore a National Pollution Discharge Elimination System (NPDES) Construction StormWater permit is required from the State Water Board (under CWA 402). The project has prepared a SWPPP and filed the NOI. The NOI/SWPPP will incorporate both the Grizzly and Lower Bucks Dam Geomembrane Installation Project ground impact areas. 3. PG&E hydroelectric facilities, assets, and activities that are within FERC boundaries and subject to FERC licensing and regulatory requirements, are not subject to state or local law (Federal Power Act preemption). a. Therefore, the proposed project is preempted from California Fish and Game Code 1602 and a Lake and Streambed Alteration Agreement is not required from the California Department of Fish and Wildlife b. The project is preempted from state Porter-Cologne Water Quality Control Act regulations managed by the Regional Water Board. c. Plumas County jurisdiction is also preempted; no permit is required from the County. In addition, Plumas County has waived its jurisdiction in the past for hydro power projects taking place on Utility-owned lands or federally owned lands (2010 CBC defines County authority over Nonstate-regulated buildings, structures and applications. California Government code Section 53091 exempts public utilities from local building and planning ordinances and Federal law exempts federal projects and properties from local building and planning ordinances unless voluntary request inclusion in the permit process). This work does not take place on a dam, thus no DSOD approval is necessary. PG&E provided the PD to the Plumas National Forest (PNF), and will provide a sediment sampling plan for review/concurrence. Analytical results of the sediment sampling will be submitted to PNF for review and approval for placement of dredged materials on PNF land. Temporary Bypass Piping. Provide additional information on the temporary bypass piping noted on Drawings 3101949 and 3101950. 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Enclosure 1 Grizzly Forebay Dam Low-Level Outlet Modification Project Responses to Comments from FERC dated May 8, 2020 Page 4 Response: PG&E will provide for FERC review a copy of its Temporary Bypass Water Plan, which includes additional information regarding the proposed temporary water bypass system. Final Design Criteria Memorandum. Describe how the reconfigured low-level outlet system would mitigate overspray from the new fixed cone valve from hitting the dam face. Response: The LLO modificationwill limit overspray from the fixed cone valve (FCV)onto the downstream face of the dam by redirecting the spray into the plunge pool using a steel valve cage as noted on Drawing No. 394863. Hydraulic Calculations. Section 3 shows a comparison of the elevation-discharge curves from the 2006 vs. 2019 analyses. Verify that the new low-level outlet system is designed for a lower discharge capacity compared to the existing system. Response: As shown on Drawing 3101950, the discharge capacity is expected to be slightly lower than the existing LLO valve configuration due to additional fittings and components The proposed low- level outlet modifications have been designed to meet current and anticipated forthcoming IFR requirements for the range of operational elevations at Grizzly Forebay. The hydraulic calculations accounted for increased head losses as a result of additional fittings and components and confirmed that the modification will meet operational needs. Larger pipes were considered but were deemed unnecessary to meet flow requirements and would likely present constructability issues due to the amount of available space. 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Prepared For:David Ritzman, P.E., G.E., Chief Dam Safety Engineer Prepared By: Jeff Jukkola, P.E., Responsible Engineer Brendan Graves, Project Manager Reviewed By: Ben Fontana, P.E., DamSafety Engineer Cathy Ly, P.E., Deputy Chief Dam Safety Engineer Copies: Jamie Visinoni, License Coordinator Date: June 5, 2020 Grizzly Dam Low Level Outlet Modification Project (FERC No. Subject: 619) – PG&E Response to COVID-19 Contingencies This memorandum presents Pacific Gas and Electric Company’s (PG&E’s) response to a request from the Federal Energy Regulatory Commission (FERC) to develop mitigation and contingency plans to address potential impacts from the COVID-19 pandemic on construction of the Grizzly Dam Low Level Outlet (LLO) Modification Project. Grizzly Dam is part of PG&E’s Bucks Creek Hydroelectric Project,FERC No. 619. PG&E submitted the project design package to FERC on April 8, 2020,and received FERC’s review comments in a letter dated May 8, 2020. FERC’s first comment from May 8, 2020, requested additional information regarding PG&E’s plans to address COVID-19 concerns. This comment is copied below and followed by PG&E’s response. General Comment No. 1 from FERC, Received May 8, 2020 PG&E personnel must contact this office to discuss the possibility of this work being interrupted from the COVID-19 pandemic. PG&E must explain if delays or the absence of key workers (e.g., contractors, drillers, geologists) could leave the project in a compromised position and, if so, what contingencies will be in place to prevent this from happening. PG&E must also provide a written description of these contingencies prior to start of construction. We may rescind the authorization to start construction if PG&E cannot adequately address these issues. 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Grizzly Forebay Dam LLO ModificationProject (FERC No. 619) PG&E Response to COVID-19 Contingencies PG&E Response PG&E’s plans include measures to protect project personnel from exposure to the COVID-19 virus and contingency plans to allow project construction to continue if crew members become infected with the virus. PG&E’s contingency plans are intended to mitigate potential risks to the project if critical staff are not available, equipment and material supply are disrupted, or contractual relationships are affected by the COVID-19 pandemic. PG&E’s COVID-19 contingency and mitigation plans have been developed through collaboration with PG&E inspectors, subcontractors,consultants, and key project personnel.PG&E and the project team recognize that public and employee safety and the continued safe operation of Grizzly Forebay LLO are of paramount importance. Once project construction is initiated, PG&E has the resources and plans in place to continue the work until the Grizzly LLO is returned to service. As a result of the information presented below, the project team is confident that we will be able to successfully complete construction of the project. 1. Overall Approach and Critical Points in Schedule: Syblon Reid Contractors(SRC) will be the prime constructor performing the modifications to the LLO piping. Before SRC starts work, Rain for Rent is under contract to install the Grizzly Creek instream flow bypass system, provide pump watch and generators for the instream flow requirement (IFR) bypass system (see Enclosure 3). 2. Readiness for Construction: All materials and equipment will be delivered to the site starting approximately June 15, depending on the reservoir elevation. All construction contracts have been executed and the contractors will be mobilizing after the Grizzly Forebay spilling subsides. SRC has already procured all materials from local suppliers within California. 3. PG&E Employee and Contractor Safety: PG&E employees and contractors are taking actions to help prevent the infection of employees and subsequent spread of the COVID-19 virus.These actions are summarized below: All employees are required to take their temperature before reporting to work.If any employee exhibits a fever greater than 100 degrees Fahrenheit, they must remain home. Personnel do not carpool to sites; they take separate vehicles to reduce close contact between employees. Tailboards (safety briefings) are held remotely or in larger circles outside, where recommended social distancing of 6 feet can be maintained. Page 2 of 6 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Grizzly Forebay Dam LLO ModificationProject (FERC No. 619) PG&E Response to COVID-19 Contingencies Traditional office employees (manager, supervisors, clerks, engineers, project management analyst) are working from home to limit exposure to field crews, thus reducing potential exposures for field crews. This is especially critical for support employees who travel systemwide.Keeping nonessential personnel at home reduces the risk of infection from other areas. All employees are required to follow PG&E guidance on personal protective equipment (PPE) and practices to protect themselves and others from viral transmission.This means maintaining social distancing where possible, wearing a cloth mask or Flame Resistant (FR) face/neck gaiters while working around other people, covering coughs or sneezes, avoiding touching others and shared surfaces, frequently washing hands with soap and water or using hand sanitizer with at least 60 percent alcohol, and avoiding touching one’s face. Daily tailboards include discussion of work activities that may interfere or conflict with social distancing practices, including ways to adjust those practices and implement additional mitigation measures as needed to perform the work safely. Daily tailboards also discuss PPE and sanitation requirements. Crews have been isolated, meaning that employees have not been transferred from crew to crew to minimize cross-crew contamination. Additional cleaning/sanitizing has been ordered for group areas, such as breakrooms, bull rooms, and bathrooms (including portable restrooms). 4. Mitigation Measures Specific to the Grizzly LLO Modifications Project: If one of the employees working on the project gets infected, then staff will follow the company guidance (outlined below), including all employees staying home for 14 days. While the employees are gone, the site would be sanitized by a separate group. In the event of a 14-day shutdown, contractors will be able to recover a possible 14-day loss by adjusting the work schedule. The project is currently scheduled to work a 5-10 (5 days per week, 10 hours per day) schedule. Subcontractors have confirmed that their respective schedules can be modified to a 7-10 schedule, as necessary, to make up the time lost. Because this is a 5- to 6-week total duration project, and the outage is scheduled through November, the scheduled completion date is flexible. As an alternative to a full 14-day shutdown, SRCand Rain for Rent could mobilize another crew from other California-based staff pools to maintain production after the site is sanitized. o SRC has allocated a staff of four to six employees based on the phase of work. If a member of this crew falls ill, SRC has approximately 10 employees previously approved to work on PG&E projects to fill in as needed to replace the affected crew. o Rain for Rent has allocated four employees to support this project. If a member of this crew falls ill, Rain for Rent has 12 large operation centers within California and more than 100 employees previously approved to work on PG&E projects to fill in as needed to replace the affected crew. Page 3 of 6 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Grizzly Forebay Dam LLO ModificationProject (FERC No. 619) PG&E Response to COVID-19 Contingencies Separate sanitary facilities (temporary restrooms and sinks) will be provided for contractors, employees, and each crew to reduce risk of exposure. Signage will be placed on the facilities to instruct users on the proper facilities to use. If a contractor employee is infected and PG&E employees are not exposed, the job will be shut down for approximately 4 days to sanitize the site, after which work will resume. If exposed contractor employees need to be quarantined for 14 days, each contractor employee will implement measures to make up the lost workdays (e.g., modify the work schedule or use a separate crew) after the 4-day sanitation period. All contractors are bringing in more trucks to avoid carpooling for social distancing. All contractors will comply with PG&E guidance for COVID-19. All contractors have the resources to replace their entire crew if needed. PG&E’s project inspector will be onsite for quality control monitoring. If the inspector gets sick, PG&E will replace himor her with another preapproved inspector. A redundant inspector has been identified, and transitioning to a backup inspector can occur with minimal delay. Site visits from other PG&E employees, or contractors not part of the essential construction crews, will be limited to essential trips. Reasons for essential trips include witnessing quality hold points, safety checks/audits, and construction progress monitoring. There may be critical hold points that require regulatory approval from FERC and California Department of Water Resources, Division of Safety of Dams (DSOD). PG&E will work with FERC and DSOD to confirm hold points in advance and identify backup personnel (if the primary field engineer is unavailable) and other contingency options. The following PG&E guidance and Center for Disease Control (CDC) recommendations will be followed for sick employees or contractor response if an employee or contractor becomes ill onsite or later reports a positive test for COVID-19. PG&E’s COVID-19 GUIDANCE FOR OUTAGE WORK Sick Employee or Contactor Response For any employee that appears or reports that they are ill. Call CareOnSite for medical evaluation – 877-888-8656 If employee has symptoms of COVID-19 (fever, cough, shortness of breath), follow instruction from CareOnSite. When PG&E receives notification of a positive COVID-19 test for someone that has been onsite. 1. If it is a PG&E employee, the appropriate PG&E Supervisor/Manager of the infected employee will: i. Contact HR Helpline and Management. ii. Identify all persons that had recent contact (or potential contact) with that person. iii. Send these employees home for two weeks. iv. Follow corporate guidance. Page 4 of 6 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Grizzly Forebay Dam LLO ModificationProject (FERC No. 619) PG&E Response to COVID-19 Contingencies 2. If it is a Contract employee, the vendor will contact the appropriate PG&E representative (Onsite PG&E inspector or the project manager) who will: i. Contact HR Helpline and Management. ii. Identify all persons that had recent contact (or potential contact) with that person. iii. Send these employees home for two weeks. iv. Follow corporate guidance. 3. No one that has tested positive for COVID-19 may return to work until they are symptom free per the CDC guidance below. 4. Sanitize facility while employees are off site. 5. Resume work, with crews that are willing to report. CDC Recommendation People with COVID-19 who have stayed home (home isolated) can stop home isolation under the following conditions: o If you will not have a test to determine if you are still contagious, you can leave home after these three things have happened: you have had no fever for at least 72 hours (that is three full days of no fever without the use medicine that reduces fevers) AND other symptoms have improved (for example, when your cough or shortness of breath have improved) AND at least 7 days have passed since your symptoms first appeared o If you will be tested to determine if you are still contagious, you can leave home after these three things have happened: you no longer have a fever (without the use medicine that reduces fevers) AND other symptoms have improved (for example, when your cough or shortness of breath have improved) AND you received two negative tests in a row, 24 hours apart. New Site Visitor Screening & Weekly Tailboard Questions PG&E crews and Inspectors will tailboard these questions weekly at a minimum. Work groups have the option to ask these questions daily as well. New visitors will be screened upon or prior to arrival. 1. Did you or someone you live with return from or travel through airports in a Level 2 or 3 country listed by the CDC within the last 14 days? a. The current list of Level 2 or 3 will be provided weekly by the EOC to the PG&E supervisors and contract inspectors. 2. Did you or someone you live with have extended (greater than 2 cumulative hours), close contact (less than 6 feet) with someone who traveled to a Level 2 or 3 country listed by the CDC within the last 14 days? 3. Have you or someone you live with been notified of being exposed to a person with the COVID-19 virus or any other respiratory illness? 4. Can you verify that you are currently healthy and have not had any cold or flu symptoms in the past 7 days (fever, cough, or shortness of breath)? Page 5 of 6 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Grizzly Forebay Dam LLO ModificationProject (FERC No. 619) PG&E Response to COVID-19 Contingencies If the answer to any of these questions is “YES” please immediately notify your PG&E work supervisor or onsite inspector. The respective supervisors or inspectors will follow the appropriate company direction for managing sick or compromised employees and contractors based on the current COVID-19 response plans. 5. Public Safety: The work at Grizzly Forebay requires PG&E to close public access to the lake for the summer/fall of 2020. To ensure public safety, the U.S. Forest Service (USFS) road to Grizzly Forebay will be closed for the recreation season. PG&E’s contractors can work safely with large trucks and heavy equipment and minimize interaction with people who are not essential to the work. The USFS campsites at Grizzly Forebay will be closed for the duration of the project. PG&E has updated the recreation website and will post signage along the road to the site to provide public notice. USFS has updated the recreation website and announced formal closure of the roads associated with the project access routes. The public may ignore posted signage and disregard campground closure notification, causing nuisance on the site. However, signage and locked gates will help deter nuisance activity. In addition, the site will be manned 24/7 to help ensure the IFR bypass system remains operational, which will help deter nuisance activity. 6. Critical Work: To properly prepare and plan for potential COVID-19–related project shutdowns that might reduce PG&E’s ability to restore the dam to operational condition, PG&E has identified the following critical work that, once begun, would require completion of the project or modifications to the design documents. After the LLO valve and piping is removed during the demolition phase of the project, the new piping and valving would need to be completed or alternative details would need to be developed to restore the minimum IFR before the bypass pumping could be taken offline. In preparation for potential unforeseen delays or issues, the project team has enough time built into the remaining season/outage to complete the work with another crew, assuming the work begins in July. As described above, the outage is scheduled from July to November. The replacement of the piping, valving, and support structure is not specialty civil work and could be performed by another civil contractor or PG&E’s General Construction crews. Other than the abovementioned critical work, we do not anticipate any other work that would introduce temporary vulnerabilities if the project were catastrophically affected by an outbreak of COVID-19.

If there is any conflict between operational standards set forth by the ADCI and another organization such as OSHA, or PG&E protocol, Global Diving and Salvage will follow whichever rule is the most conservative when applied to the safety of any person working at the site. All site activities will also comply with the following regulations and guidance publications: Occupational Safety and Health Administration Construction Industry Standards, 29 CFR 1926 Occupational Safety and Health Administration General Industry Standards, 29 CFR 1910 CAL OSHA, Title 8, Chapter 4, Subchapter 8, General Industry Safety Orders and Construction Safety Orders Other applicable federal, state, and local safety and health requirements, including the Global Diving & Salvage, Inc, Manual of Safe Diving Practices. 2.0 Site Background PG&E and the City of Santa Clara co-own the Bucks Creek Hydroelectric Project FERC No. 619. The 84.8 MW project is fed by Bucks, Grizzly and Milk Ranch Creeks in Plumas County, California. The main reservoirs that support the project are Upper Bucks Lake, Lower Bucks Lake, Three Lakes Reservoir, and Grizzly Forebay. The project discharges water into the North Fork of the Feather River through Bucks Creek Powerhouse. In Grizzly Forebay silt, sand, and organic material has accumulated over the years. Global performed an inspection in 2013 and found logs and debris up to one (1) foot diameter built up at the base of the intake, at the base of the dam, and near the Low Level Outlet (LLO). This project intends to remove the debris from the reservoir adjacent to the LLO and the intake structure. PG&E ATS division performed a multi-beam survey of the reservoir in October of 2017. The multi-beam data was compared to 1925 contours to determine an amount of debris build up. An area of debris removal was identified in front of the Bucks Powerhouse Intake and in the vicinity of the LLO. The volume of proposed debris removal is 3160 cubic yards. This material is impacting the intake and LLO with sediment being drawn into the power tunnel with the generation flows. The sediment is causing deterioration to the runners of the units causing increased maintenance. Debris build up may also be drawn into the LLO which could affect its reliability. tD͵ Ќ 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Date of Submittal: 08 April 2020 3.0 Work Scope Summary The purpose of this project is to remove approximately 3,160 cubic yards of sub surface debris, silt, sand, gravel buildup from within the Grizzly Forebay. All removed material will be hauled to an offsite location for future removal by PG&E. 4.0 Instream Flow Release Water Flows of up to 12 CFS will need to be maintained throughout the project. Typically the flows are through the LLO which will be removed from service daily due to turbidity and the dredging near the outlet. A primary bypass system, capable of the required flows, and a fully redundant independent backup system capable of being started immediately if the primary system fails, will be installed and maintained. This submittal will detail the installation and support for the water bypass Global will sub- contract to Rain For Rent. 5.0 Water Bypass System 5.1 Bypass Outline and Makeup Prior to beginning dredging, the water bypass system will be set up for Instream Flow Release (IFR). To house the bypass system, an independent barge module platform will be constructed. This will be accomplished during the MOB phase at the same time the main dredging barge, and the (2) material barge platforms are being assembled. All efforts will be made through trucking and crane logistics to assemble the bypass barge first, to allow Rain For Rent the opportunity to install the bypass system during the remaining mobilization period for the dredging and support equipment. The bypass system will consist of a primary and fully redundant backup system, each with separate 240kv generator power sources. The submersible pumps will have a run of pipe floating on the surface of the reservoir to the spillway of the dam. The system will be capable of producing 2 CFS minimum, up to 12 CFS. As the reservoir draws down, the pumps will need to maintain the required flows to a potential 15 foot head. The intake of the submersible pumps attached to the bypass barge will draw from the exterior of theturbidity curtain, so as not to draw within the dredging area. tD͵ Ѝ system. pumping bypass the 2020 needed) April (if 8 0 repair and Date of Submittal:maintain, barge. g operate, to pumpin e hours of th t Barge Ў ͵ layou daylight D d t during Pumping expecte e th onsite s be will depict w belo technicians mage Water Bypass System i e Pump 5.2 Th 2020 April 8 0 Date of Submittal: Џ ͵ D t 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Date of Submittal: 08 April 2020 5.3 Bypass Equipment and Ancillary Gear List The water bypass will be provided and maintained by Rain For Rent and associated personnel. All pumps will require a VFD. VFD for the pumps will run on target level control at the suction location where the VFD will maintain a level specified by the customer via two (2) submersible pressure transducer. These levels will be starting levels and may and will change during the finetuning of the system during startup. One transducer shall operate three pumps via an AnDRU Box and will be wired to the 2-pin connector that will connect to the 2-pin connection on the AnDRU box. The transducer must be set a transducer. Transducer must be installed in a way were they can be removed and reinstalled quickly and easily but once installed, the stilling tubes should be anchored in a way and in an area where it will read the full depth of the pit and where it will not be thrashed around by the suction of the pump or the flow into the pit to help prevent damage to the transducer. Since this application involves sewage, the transducer must be inspected regularly to make sure that no solids clog the protective cage around the diaphragm. The stilling tube should be capped at the bottom to prevent the transducer from slipping out. 1/2" holes will need to be drilled every 6" on one side (full height). Three channel's on alarm agent will be used to monitor VFD fault. Terminals 25 and 26 on each VFD will be used to connect to the corresponding channel to alert of a fault. The AnDRU Box 6-pin (Wires A & B) will connect to the VFD of the first pump via terminals 5 & 9.Wire A will connect to terminal 5 and Wire B will connect to terminal 9. The VFD must be programmed for automatic target level control. This will allow the pump to ramp up and down based on the level of the lake. The AnDRU Box 6-pin (Wires C & D) will connect to the VFD of the second pump via terminals 5 & 9. Wire C will connect to terminal 5 and Wire D will connect to terminal 9. The VFD must be programmed for automatic target level control. This will allow the pump to ramp up and down based on the level of the lake. The AnDRU Box 6-pin (Wires E & F) will connect to the VFD of the third pump via terminals 5 & 9.Wire E will connect to terminal 5 and Wire F will connect to terminal 9. The VFD must be programmed for automatic target level control. This will allow the pump to ramp up and down based on the level of the lake. The last pump will have its own transducer and it's red and black wires will be wired to the VFD at terminal 10 and 5 respectively. The pump must be set to auto and be programmed to analog in. The transducers will allow the pump to ramp up and down based on level. 10 minutes of reservoir space is needed between the on (min RPM) and the max RPM of each pump. tD͵ А 31311727.6128!GFSD!QEG!)Vopggjdjbm*!702603131!9;33;61!QN Date of Submittal: 08 April 2020 Minimum of 30Hz without a fan, may proceed lower with cooling and approval but can't go down to 0%. The motor must be 480 three phase. The motor must be inverter duty or at least have insulation of class F or better. Branch must program the motor nameplate information into the VFD so the VFD know what pump it is controlling. This is done in group 99. Branch must also program safety limits into the VFD based on the pumps motor nameplate information. This is done in group 20. Relay #1 on the AnDRU Box will be programmed to "Dry Run Protect" and will be programmed to levels chosen by the customer to be High Water Level. Relay #1 will be wired to the Alarm Agent via the A & B pins on the AnDRU Box 7-pin connector and to a corresponding channel on the Alarm Agent. Relay #2 on the AnDRU Box will be programmed to "Dry Run Protect" and will be programmed to levels chosen by the customer to be High Water Level. Relay #2 will be wired to the Alarm Agent via the C & D pins on the AnDRU Box 7-pin connector and to a corresponding channel on the Alarm Agent. Relay #3 on the AnDRU Box will be programmed to "Dry Run Protect" and will be programmed to levels just before the Backup Pump is to turn on. Relay #3 will be wired to an A/V Tower via the E & F pins on the AnDRU Box 7-pin connector and to either the Amber or Red light on the A/V Tower. The horn can be rewired to either channel if chosen to be used. The AnDRU Box 19 pin (Wires S & T) will connect to the Alarm Agent in case of AnDRU Box failure. Alarm Agent will run off of 120 VAC via the plug off of the Alarm Agent. A/V Tower will run off of 120 VAC. 120 VAC required on site.
