5. PLC TEST
A. Components
PLC interior High Temperature alarm is installed, wired to the PLC, and is shown to be functional.

Relays have transient suppression across their coils. This is particularly important for DC coil relays, where diodes in reverse polarity are often used.

TVSS is installed across the main incoming 120 VAC.

PLC and PLC Rack
Verify all cards are securely seated.

Ensure clearance around PLC rack has been met, such that convective heat transfer is not impeded by devices erroneously mounted in the “no encroachment” area. Confirm with manufacturer clearance recommendations.

B. PLC I/O Test
Furnish I/O test forms and test all the listed input and output points as follows:

Discrete Inputs: Simulate a field contact closure by “shorting” across the appropriate terminal blocks.

Observe the transition between a logical “0” and “1” in the PLC software.

Discrete Outputs: Force the output bit to toggle between logical “0” and logical “1” using the PLC software.

Measure contact resistance at the wired terminal blocks using a digital meter selected for the “ohms” setting.

Analog Inputs: Connect a signal generator to the appropriate terminal blocks. Tailor the connection depending on whether a 2-wire or 4-wire simulation is required. Modulate the 4-20mA signal. Observe the associated PLC internal memory register to transition between 0-65535 or if scaled in engineering units, between 0 and the maximum scaled engineering unit. The latter method is preferred.

Analog Outputs: Force the output register to a value between 0-65535 or 0-100%, if the scaling block can be manipulated. Observe the measured 4-20mA value increment and decrement using a digital ammeter.

PLC Control Logic Verification
The PLC control strategy is verified by following the Control Logic Verification Form based on the specifications.

Each control strategy will be verified by simulating the process and checking the state or value of PLC outputs.

The results of equipment status and alarms and process instrument values and trends shall also be verified on the Plant SCADA graphic screens stored in a temporary SCADA computer. Since all PLC input and output wiring has been verified and some field devices are not available during Factory Acceptance Testing, certain inputs will be simulated either by means of additional hardware and/or software as described below.

DI states are either simulated by hardwired switches or forced inputs using a programming terminal.

For example, when starters and drives are not provided as part of the contract, jumpers may be installed from the output call relays to the running confirmation inputs to simulate the running state of the motors.

D. PLC Control Logic Verification (continued)
Typical Fault Logic
If the fault input is high and the disable (if applicable) for the fault is not high and the common disable (if applicable) is not high begin timing. If any of these conditions changes, stop timing and reset the timer. If the timer reaches its preset, activate the alarm output. If the fault alarm is a shutdown alarm stop the associated motor and latch the alarm so that it remains present even if the condition clears.

The fault condition must return to normal and the alarm must be reset for a latched alarm to clear.

Typical Fail to Start Logic
If the motor is called to run (call output high) and no running feedback is received (running input is low) and the fail to start and common alarm disables (if applicable) are not high start timing. If any of these conditions changes, stop timing and reset the timer. If the timer reaches its preset, activate the alarm output, stop calling the motor and latch the alarm.

Recycled Water Project City of Ukiah
Mitigation Monitoring and Reporting Program
2 INTRODUCTION
Pursuant to the California Environmental Quality Act (CEQA; Public Resources Code Section 21000, et seq. and CEQA Guidelines), the City of Ukiah, California (City) prepared a Public Draft Initial Study/Mitigated Negative Declaration (IS/MND) to evaluate potential environmental impacts associated with the City’s proposed Recycled Water Project (Proposed Project/Action). The purpose of the Proposed Project/Action is to replace/augment existing water supplies in Ukiah Valley. Recycled water use within the Ukiah Valley would offset existing and future water demands for irrigation and frost protection of agricultural land, and in doing so, would support the local agricultural industry. It would also offset urban irrigation demands, ease storage limitations at the Ukiah Wastewater Treatment Plant (UWWTP) and reduce treated wastewater discharges to the Russian River.

CEQA Guidelines require public agencies to adopt a Mitigation Monitoring and Reporting Program (MMRP) for changes to the project which it has adopted or made a condition of project approval in order to mitigate or avoid significant effects on the environment. A MMRP is required for the proposed project because the IS/MND identifies potentially significant adverse impacts related to project implementation, and mitigation measures have been identified to reduce those impacts.

On March 27, 2013, to initiate public review of the Draft IS/MND, the City filed a Notice of Completion (NOC) for the project with the Governor’s Office of Planning and Research (State Clearinghouse or SCH) and the County of Mendocino and released the Draft IS/MND for a 30-day public review. The State Clearinghouse identified the project with SCH #2013032072. The public review period was established between March 27 and April 26, 2013, with copies of the Draft IS/MND available for review at the City’s Public Works Administration Office, at 300 Seminary Avenue, Ukiah, CA 95482; and the Main Branch Library, 105 North Main Street, Ukiah, CA 95482. On March 27, 2013, the Ukiah Daily Journal published the Notice of Intent/Notice of Availability (NOI/NOA) to adopt a Mitigated Negative Declaration for the Proposed Project/Action. A Public Draft of the IS/MND was also posted on the City’s website at
http://www.cityofukiah.com/.

In May 2013, the City prepared a Final IS/MND according to CEQA Guidelines and incorporates all comments received by the State Clearinghouse and the City during the 30-day public review period. As a result, some of the mitigation measures identified in the Public Draft IS/MND have been revised to reflect those comments. Based on the Final IS/MND, the Proposed Project/Action would not result in new significant impacts, substantially increase the severity of previously disclosed impacts, or involve any of the other conditions related to changed circumstances or new information that can require a subsequent or supplemental EIR under Public Resources Code section 21166 and CEQA Guidelines section 15162 beyond those impacts and conditions already identified in the City’s Public Draft IS/MND.

PURPOSE OF MITIGATION MONITORING AND REPORTING

PROGRAM
This MMRP has been prepared to ensure that all required mitigation measures are implemented and completed in a satisfactory manner before and during project construction and operation. The MMRP may be modified by the City during project implementation, as necessary, in response to changing conditions or other refinements. Table A (included at the end of this document) has been prepared to assist the responsible parties in implementing the mitigation measures. The table identifies individual mitigation measures, monitoring/mitigation timing, responsible person/agency for implementing the measure, monitoring and reporting procedure, and space to confirm implementation of the mitigation measures.

The numbering of mitigation measures follows the numbering sequence found in the Public Draft IS/MND.

ROLES AND RESPONSIBILITIES
Unless otherwise specified herein, the City is responsible for taking all actions necessary to implement the mitigation measures under its jurisdiction according to the specifications provided for each measure and for demonstrating that the action has been successfully completed. The City, at its discretion, may delegate implementation responsibility or portions thereof to a licensed contractor or other designated agent. The City would be responsible for overall administration of the MMRP and for verifying that Appendix A-3 8660F10 July 12, 2023 - CONFORMED

Recycled Water Project City of Ukiah
Mitigation Monitoring and Reporting Program
3 City staff members and/or the construction contractor has completed the necessary actions for each measure.

The City would designate a project manager to oversee implementation of the MMRP. The City of Ukiah’s Public Works Department is primarily responsible for implementing the mitigation measures for the Proposed Project as described in this MMRP. Duties of the project manager include the following:
 Ensure that routine inspections of the construction site are conducted by appropriate City staff; check plans, reports, and other documents required by the MMRP; and conduct report activities.
 Serve as a liaison between the City and the contractor or project applicant regarding mitigation monitoring issues.
 Complete forms and maintain reports and other records and documents generated by the MMRP.
 Coordinate and ensure that corrective actions or enforcement measures are taken, if necessary.

The responsible party for implementation of each item would identify the staff members responsible for coordinating with the City on the MMRP.

REPORTING
The City’s project manager shall prepare a monitoring report, upon completion of the project, on the compliance of the activity with the required mitigation measures. Information regarding inspections and other requirements shall be compiled and explained in the report. The report shall be designed to simply and clearly identify whether mitigation measures have been adequately implemented. At a minimum, each report shall identify the mitigation measures or conditions to be monitored for implementation, whether compliance with the mitigation measures or conditions has occurred, the procedures used to assess compliance, and whether further action is required. The report shall be presented to the City Council.

MITIGATION MONITORING AND REPORTING PLAN TABLE
The categories identified in Table A are described below.  Mitigation Measure – This column provides the text of the mitigation measures identified in the IS/MND.
 Timing – This column identifies the time frame in which the mitigation will take place.
 Enforcement – This column identifies the party responsible for enforcing compliance with the requirements of the mitigation measure.

3.3 AIR QUALITY
Mitigation Measure AIR-1: Dust Control. During all phases of construction, the following dust control procedures shall be implemented:
 Water all active construction sites as necessary.
 Cover all trucks having soil, sand, or other loose material or maintain at least two feet of freeboard on all trucks.
 Apply water as necessary, or apply non-toxic soil stabilizers on all unpaved access roads, parking areas and staging areas at construction sites.
 Sweep if visible soil material is carried into adjacent streets.  Water or apply non-toxic soil binders to exposed soil stockpiles.  Limit traffic speeds on unpaved areas to 15 mph.

3.4 BIOLOGICAL RESOURCES
Mitigation Measure BIO-1: Conduct Breeding/Nesting Surveys. For construction activities that occur between February 1 and August 31, preconstruction breeding bird surveys shall be conducted by a qualified biologist prior to and within 10 days of any initial ground-disturbance activities. Surveys shall be conducted within all suitable nesting habitat within 250 feet of the activity. All active, non-status passerine nests identified at that time should be protected by a 50 foot radius minimum exclusion zone. Active raptor or specialstatus species nests should be protected by a buffer with a minimum radius of 200 feet. CDFW and USFWS recommend that a minimum 500-foot exclusion buffer be established around active white-tailed kite and golden eagle nests. The following considerations apply to this mitigation measure:
 Survey results are valid for 14 days from the survey date. Should ground disturbance commence later than 14 days from the survey date, surveys should be repeated. If no breeding birds are encountered, then work may proceed as planned.
 Exclusion zone sizes may vary, depending on habitat characteristics and species, and are generally larger for raptors and colonial nesting birds. Each exclusion zone would remain in place until the nest is abandoned or all young have fledged.

 The non-breeding season is defined as September 1 to January 31.

During this period, breeding is not occurring and surveys are not required. However, if nesting birds are encountered during work activities in the non-breeding season, disturbance activities within a minimum of 50 feet of the nest should be postponed until the nest is abandoned or young birds have fledged.

Mitigation Measure BIO-2: Conduct A Preconstruction Survey for Western Pond Turtles and Relocate, if Necessary. A qualified biologist shall conduct a pre-construction survey for western pond turtles no more than 30 days prior to construction in suitable aquatic habitats within the project corridor, including stream crossings, drainage ditches, and culverts. A combination of visual and trapping surveys may be performed with authorization from CDFW. If the species is found near any proposed construction areas, impacts on individuals and their habitat shall be avoided to the extent feasible. If occupied habitat can be avoided, an exclusion zone shall be established around the habitat and temporary plastic fencing shall be installed around the buffer area with “Sensitive Habitat Area” signs posted and clearly visible on the outside of the fence. If avoidance is not possible and the species is determined to be present in work areas, the biologist with approval from CDFW may capture turtles prior to construction activities and relocate them to nearby, suitable habitat a minimum of 300 feet downstream from the work area. Exclusion fencing should then be installed if feasible to prevent turtles from reentering the work area. For the duration of work in these areas the biologist should conduct monthly follow-up visits to monitor effectiveness.

Mitigation Measure BIO-3: Avoid cutting through the creeks. As described in the Proposed Project/Action description, all of the creek crossings will be crossed by using trenchless construction techniques in the dry season.

Specifically, no pipeline construction activities shall occur between December 1 and May 31 (a work window identified by the National Marine Fisheries Service), which is the period when adult and juvenile salmonids are likely to occur in the Russian River. Construction crews shall avoid entering the stream channels during installation.

measures: Avoidance of construction activities during inclement weather; limitation of construction access routes and stabilization of access points; stabilization of cleared, excavated areas by providing vegetative buffer strips, providing plastic coverings, and applying ground base on areas to be paved; protection of adjacent properties by installing sediment barriers or filters, or vegetative buffer strips; stabilization and prevention of sediments from surface runoff from discharging into storm drain outlets; use of sediment controls and filtration to remove sediment from water generated by dewatering; and returning all drainages to preconstruction conditions. Construction crews shall avoid entering the stream channels during installation.

Mitigation Measure BIO-5: Develop and Implement a Frac-Out Contingency Plan for Trenchless Construction Activities. For trenchless construction activities that use drilling lubricants, the City or its contractor shall prepare and implement a frac-out contingency plan that is intended to minimize the potential for a frac-out associated with tunneling activities; provide for the timely detection of frac-outs; and ensure an organized, timely, and “minimumimpact” response in the event of a frac-out and release of drilling lubricant (i.e., bentonite). The contingency plan will require, at a minimum, the following measures.
 Trenchless construction activities to be conducted during a work window identified by the National Marine Fisheries Service when adult and juvenile salmonids are not present in the project area (June 1 through November 30).
 A full-time monitor will attend all drilling to look for observable fracout conditions or lowered pressure readings on drilling equipment. If a frac-out is identified, all work will stop, including the recycling of drilling lubricant. In the event of a frac-out into water, the pressure of water above the tunnel will keep excess mud from escaping through the fracture. The location and extent of the frac-out will be determined, and the frac-out will be monitored for 4 hours to determine whether the drilling lubricant congeals (bentonite will usually harden, effectively sealing the frac-out location).
 If the drilling lubricant congeals, no other actions will be taken that would potentially suspend sediments in the water column.  Surface releases of bentonite will be allowed to harden and then will be removed.

 The contingency plan will identify additional measures to be taken to contain or remove the drilling lubricant if it does not congeal.

Mitigation Measure BIO-6: Obtain all Required Authorizations. Prior to issuance of encroachment permits for the Proposed Project/Action, the City, as necessary, shall conduct a wetlands delineation study in sensitive areas of the Proposed Project/Action and obtain all required authorization from agencies with jurisdiction riparian habitats and jurisdictional wetlands in the area. Such agencies may include, but are not limited to, the United States Army Corps of Engineers, the California Department of Fish and Wildlife, and the North Coast Regional Water Quality Control Board. Impacted habitat shall be offset through onsite restoration, offsite restoration, or purchase of credits at a CDFW and USFWS-approved mitigation bank in the region at no less than a 1:1 ratio.

3.5 CULTURAL RESOURCES
Mitigation Measure CR-1: Conduct Pre-construction Survey and Avoidance of Identified Cultural Resources. Prior to and/or during the engineering and final design phase, a qualified professional archeologist or cultural resources specialist will provide a final pre-construction survey of the exact proposed pipeline alignment and placement of the project facilities within the proposed construction corridor and ensure that the construction activities of the Proposed Project/Action will not affect the archeological resources P-23- 004814, P-23-004815, and P-23-003663 as identified by NWIC above. In the unlikely event that the Proposed Project/Action could affect these resources, the proposed project facilities shall be constructed in a manner that will avoid damaging these resources. Specifically, the pipeline shall either be installed by avoidance of the resource by realignment of the pipeline or facility around the resource(s) and/or as in the case of crossing the Northwestern Railroad, the resource shall be avoided by going beneath through the implementation of horizontal directional drilling (HDD) or another equally effective construction technique(s). In addition, the archeological resource sites shall include the installation of barrier fencing or other physical barriers to prevent construction personnel and vehicles from coming onto the sites during construction. During construction, the area shall be monitored by a professional archaeologist to ensure that (1) barrier fencing is maintained, (2) vehicles and workers do in fact remain off the site, and (3) violations of the exclusion area are reported and infractions are policed in accordance with treatment of other environmental violations. Any construction or post‐construction use of the road adjacent to the sites in support of the pipeline shall be confined to the road which shall be used Prior to and

Mitigation Measure CR-2: Halt work if cultural resources are discovered.

In the event that any prehistoric or historic subsurface cultural resources are discovered during ground disturbing activities, all work within 100 feet of the resources shall be halted and after notification, the City shall consult with a qualified archaeologist to assess the significance of the find. If any find is determined to be significant (CEQA Guidelines 15064.5[a][3] or as unique archaeological resources per Section 21083.2 of the California Public Resources Code), representatives of the City and a qualified archaeologist shall meet to determine the appropriate course of action. In considering any suggested mitigation proposed by the consulting archaeologist in order to mitigate impacts to historical resources or unique archaeological resources, the lead agency shall determine whether avoidance is necessary and feasible in light of factors such as the nature of the find, project design, costs, and other considerations. If avoidance is infeasible, other appropriate measures (e.g., data recovery) shall be instituted. Work may proceed on other parts of the project site while mitigation for historical resources or unique archaeological resources is carried out.

 Ensure that adequate soil drainage is maintained;
 Ensure that salt-sensitive plants are not to be spray wet; and  Addressing sodium and alkalinity concerns through addition of water and soil amendments, including addition of gypsum.

In addition and prior to operation of the recycled water system, the City shall prepare and submit for approval of the North Coast Regional Water Quality Control Board, a recycled water operations and maintenance plan and recycled water users guide to identify general and site-specific BMPs that will be implemented to ensure that recycled water will be used in a manner that protects ground and surface water. The BMPs shall address measures to protect against recycled water runoff that is not incidental, provide for detection and correction of leaks, and ensure that pollutants such as salts and nutrients are not discharged at concentrations that could adversely impact groundwater. The BMPs shall also address both agronomic irrigation and frost protection uses.

Specifically, the recycled water for irrigation BMPs shall include the type of irrigation system, proper design and operation of the irrigation system, application methods (e.g., agronomic application, use of repeat start times and multiple water days to increase irrigation efficiency and reduce runoff potential, no application during precipitation events), setbacks to surface waters, physical systems to capture runoff and prevent it from reaching surface waters. BMPs shall also describe how salts and nutrients will be managed in a manner that protects groundwater quality.

Frost protection BMPs shall include limiting frost protection use to relatively flat parcels, use of very low application rates for the shortest period possible, preseason system inspections and testing, regular in-season system checks, inspection checks during spray events that include checking for ponding and runoff, logging of spray events, and maintenance of a cover crop between vineyard rows to provide capacity for retention and limited treatment. throughout

1 1 INTRODUCTION

1.1 PURPOSE
Crawford & Associates, Inc. (Crawford) prepared this Geotechnical Report for the City of Ukiah Wastewater Treatment Plant (WWTP) Improvements as part of the Recycled Water Pipeline – Phase 4 Design Project. This report is intended to provide geotechnical and geologic data and provide conclusions and recommendations addressing the planned basin, wet well, and electrical improvements at the WWTP.

1.2 GEOTECHNICAL SERVICES
To prepare this report, Crawford:
• Discussed the project with Jason Benson, PE, with the City of Ukiah, Alan Hodge with the City of Ukiah WWTP and Brian Avon, PE and Craig Andrews with Carollo Engineers (Carollo);
• Attended a kick-off meeting at the site to meet with the design team and Alan Hodge to discuss project needs and objectives;
• Reviewed historical geotechnical data in the LACO report “Ukiah Recycled Water Pipeline, Geotechnical Report” dated October 17, 2014.
• Reviewed historical geotechnical data in the Crawford Geotechnical Report “City of Ukiah Chlorine Contact Basin Expansion, Geotechnical Report” dated November 4, 2017. • Reviewed the Carollo 60% design submittal “Storage Pond Grading Plan” dated August 2022;
• Reviewed available geologic and seismic maps;
• Drilled and sample two test borings to a maximum depth of 31.5 feet (ft) below ground surface (bgs);
• Performed laboratory tests on representative soil samples from the exploratory borings; • Performed a site-specific ground motions hazard analysis; • Performed geotechnical engineering analysis for design and construction of the proposed concrete lined basin, pump station and electrical component improvements; and • Developed conclusions and recommendations.
2 PROJECT DESCRIPTION
The City of Ukiah WWTP plans to upgrade their wastewater treatment facility by demolishing two of their existing sludge basins that are currently not in use. Following demolition of the two sludge basins, the WWTP plans to construct a new lined basin covering the area of both existing basins. In addition, the project proposes to install a wet well and electrical equipment supported on a mat foundation.

Based on the Storage Pond Grading Plan (August 2022), we understand that the current planned finished grade for the bottom of the basin is at elevation 570 ft, however we understand this elevation is flexible. The plan sheet shows that one embankment will surround the new basin. The embankment crest elevation is 581 ft and will be 13 ft wide, and the embankment slopes will be 3 horizontal to 1 vertical (3H:1V) for the inner slopes and 3H:1V for the outer Appendix B-7 8660F10 July 12, 2023 - CONFORMED

2 slopes. We understand the new embankment will be constructed by generally adding new fill to the old embankment. The new inner slopes will extend into the existing basin and sludge area.

An access road leading inside the basin is planned along the east embankment, as well as around the crown of the basin. Two inlets are planned to be on the north and east inner slopes.

We understand the new wet well will be constructed at the center of the north embankment.

The wet well is planned to be 180 sq. ft. with a planned inlet elevation of 570 ft. The wet well is planned to be founded on a mat foundation. Additionally, a shallow mat foundation will likely support the electrical components of the wet well. The electric components are proposed to be located approximately 30 ft northeast of the basin next to an existing electric panel. The details of the electric components were not established at the time of this report. 3 SITE DESCRIPTION
The existing sludge basins are located within the City of Ukiah WWTP at 391 Plant Road in Ukiah, CA. The site coordinates used for the project site are approximate latitude 39.1117° and longitude -123.1900°. We understand that the two sludge basins were originally constructed in the 1950’s as one large basin, however a berm was later constructed in the center of the basin which separated the large basin into two basins (see Photo 1 below). The basins combined measure approximately 500 ft wide by 300 ft long.

The existing ground surface within the basins range from elevation 572 ft to 574 ft. The existing berm surrounding the two basins has a surface elevation of approximately 581 ft, and the existing center berm separating the two basins has a surface elevation of approximately 576 ft.

The basin neighbors the City of Ukiah WWTP’s percolation ponds to the east, recycled water storage ponds to the south, railroads tracks to the west, and the City of Ukiah WWTP to the north.

We provide a Vicinity Map shown on Figure 1 in Appendix I.

3 Photo 1: Central Berm Showing Both Basins Facing South 4 SITE GEOLOGY
The project site lies within the Coast Ranges Geomorphic Province, characterized by a series of northwest trending mountain ranges sub-parallel to the San Andres Fault. The Coast Ranges is composed of thick Mesozoic and Cenozoic sedimentary strata. The northern Coast Ranges are dominated by the irregular, knobby, landslide-topography of the Franciscan Complex. The project site is located within the Ukiah Valley, an alluvial valley situated within the Coast Ranges.

The Geologic Map of California: Ukiah Sheet1 shows the site as being underlain by Quaternary (Recent) alluvium. The alluvium consists of predominately unconsolidated gravel, sand, silt, and clay deposited in channels and on floodplains of the Russian River (located adjacent to the facility property). Quaternary (Pleistocene) age non-marine terrace deposits are also mapped on site, which consist of gravelly clay to sandy/silty gravel.2

We provide a Geologic Map on Figure 3 in Appendix I.
5 SUBSURFACE CONDITIONS

5.1 FIELD EXPLORATION

5.1.1 SOIL BORINGS
Crawford retained Geo-Ex Subsurface Exploration to drill two exploratory borings on August 30, 2022 within the sludge basin, and Taber Drilling to drill two exploratory borings on September 27, 2017 for the nearby chlorine contact basin project. LACO retained Clear Heart Drillers to drill four borings within the existing basin embankments on September 11, 2014 for the Ukiah Recycled Water Project. Table 1 provides a subsurface exploration summary for the borings considered for this study.

1. A hammer energy calibration test was not performed specifically for this project/site; however, a previous hammer energy testing result provided by Geo-Ex found the hammer to have an energy efficiency of 101.9%.

2. A hammer energy calibration test was not performed specifically for this project/site; however, a previous hammer energy testing result provided by Taber Drilling found the hammer to have an energy efficiency of 82%.

3. A hammer energy calibration test was not recorded in the boring logs.

4. Elevations were not recorded at the time of the published report.

Soil samples were recovered by means of a 2.0-inch O.D. “Standard Penetration” split-spoon sampler without 1.4-inch stainless steel liners and a 3.0-inch O.D. “Modified California” splitspoon sampler with 2.4-inch stainless steel liners. Relatively undisturbed samples were also recovered by means of a 3-inch OD thin-walled Shelby sampler. The shelby samples were “pushed” in to recover sample and the “resistance” was measured (in psi). Drive samplers were advanced with standard 350 ft-lb striking force using a 140 lb. automatic hammer and a drop height of 30 inches. Sampler penetration resistance was recorded to provide a field measure of relative densities and can be correlated to soils strength and bearing characteristics.

Consistency of cohesive soils were obtained in the field by means of pocket penetrometer and field pocket torvanes. The field-recorded (uncorrected) blow counts and down pressure used to insert the Shelby tubes are shown on our 2022 boring logs in Appendix II. 2017 Crawford and 2014 LACO boring logs are attached in Appendix II. Boring locations are shown on the Exploration Map on Figure 2 in Appendix I.

Crawford’s project engineers and geologists logged the exploratory borings consistent with the Unified Soil Classification System (USCS) and the 2010 Caltrans Logging Manual. Crawford retained samples from the borings in sealed constrainers for laboratory testing and reference.

Groundwater observations were recorded during drilling operations when encountered. At Appendix B-10 8660F10 July 12, 2023 - CONFORMED

The Dynamic Cone Penetrometer (DCP) test provides an approximate quantification of a material’s apparent density or stiffness. For this project, DCP testing was completed using manual equipment as described below. The purpose of the test was to aid in understanding the thickness of the soft/loose sludge sediments and soil, and the depth to more competent bearing materials within the existing basins.

Crawford project engineers completed a total of two DCP tests on September 22, 2022. The DCP tests were completed using a hand-operated tool called a “Wildcat DCP,” manufactured by Triggs Technology, Inc. The test consists of continuously driving a 1.4-inch O.D. steel cone tip attached to a lead rod until refusal (50 blows per approximately 4-inches) is reached. The rods are advanced using a hand-actuated, 35-lb safety drop hammer falling a distance of 15-inches.

5.2 SUBSURFACE SOIL/ROCK
The subsurface soils encountered in the 2022 borings are generally consistent with the materials encountered in the 2017 Crawford and 2014 LACO borings and published mapping for the site vicinity. We summarize the encountered materials as described below.

Sludge Basin – The explorations completed within the existing sludge basin and center berm indicate that very soft deleterious material (likely sludge) is present to an elevation of about 566.5 ft to 567.5 ft, or about 5.5 ft to 6.5 ft below existing basin grade.

Perimeter Berm – Embankment fill consisting of tan, medium dense, silty sand was encountered from berm grade (approximate elevation 581 ft) to elevation 576 ft. The embankment fill was underlain by soft to hard lean clay and loose to medium dense clayey sand, encountered between elevations 576 ft to 550 ft. Gravelly lean clay was encountered beneath this layer at elevation 550 ft. and based on nearby borings performed for the Chlorine Contact Basin Project, this layer extends to the maximum depth explored, likely between elevations3 520 ft and 530 ft.

We present more detailed descriptions of the subsurface soils on the boring logs in Appendix II.

5.3 GROUNDWATER
We encountered groundwater in boring A-22-001 at approximate elevation 560 ft (21 ft bgs) and we did not encounter groundwater in boring A-22-002. Our 2017 borings encountered groundwater at approximate elevations 572.2 ft and 563.6 ft for borings B1 and B2, respectively.

LACO encountered groundwater in their boring B-17 at an approximate elevation of 565 ft on September 11, 2014. Based on our conversations with the city, groundwater was not encountered at the time the Chlorine Contact Basin was constructed.

The WWTP staff provided historical groundwater elevations for two monitoring wells (GW-01 and GW-02) in the vicinity of the plant for the 2017 Chlorine Content Basin report. According to 3 Actual boring elevations were not recorded for the 2017 Crawford borings. Elevations were estimated from current topographic information provided by Carollo.

7 Based on our understanding of the site conditions, flooding occurs throughout the winter months and the buoyancy forces should be estimated based on historical and/or expected high water events at the site. The recent groundwater data, from the WWTP, show the design groundwater elevation fluctuates between elevation 565 ft and 560 ft. 6 LABORATORY TESTS

8 To evaluate the potential for external corrosion potential on ductile iron pipe from soil, the 10- point system in C105/A21.5 (ANSI/AWWA 1999) was used. The 10-point system is a methodology used to determine the corrosive nature of a soil to ferrous metals based on the resistivity, pH, redox potential, sulfides presence, and drainage characteristics. The results of the 10-point system analysis showed a maximum of two points; which indicates a non-corrosive environment (AWWA 2005).

According to the American Concrete Institute (ACI) 318, a sulfate concentration less than 1,000 parts per million (ppm) is considered negligible. A chloride content of less than 600 ppm is generally non-corrosive to reinforced concrete.

Based on the results of tested samples, the soil may be generally characterized as “noncorrosive” to concrete and ferrous metals. The tests results are only an indicator of soil corrosivity and the designer should consult with a corrosion engineer if these values are considered significant.
8 BASIN CONTENTS
Soil samples were collected from the sludge basin on September 30, 2022, between elevations 567 ft to 565 ft (7.5 to 9.5 ft bgs) in boring A-22-002 (collected using a Shelby tube) and submitted to Pace Analytical (ELAP #2961) for preliminary analysis on October 25, 2022.

Samples were was analyzed for Volatile Organics (EPA Method 8260B), Purgeable Aromatics and Total Petroleum Hydrocarbons (EPA Method 8015B), and CAM 17 Metals (EPA Methods 6010B and 7471A). We summarize the results below and attach a copy of the Pace report in Appendix III.

Volatile Organics – Tetrachloroethene (0.011 milligrams/kilogram[mg/kg]), toluene (0.0051 mg/kg), and xylenes (0.0016 mg/kg) were reported in the sample; the laboratory noted that the sample was analyzed outside of hold time. These reported concentrations do not exceed applicable hazardous waste limits.

Purgeable Aromatics and Total Petroleum Hydrocarbons – Gasoline Range Organics were reported in this sample at a concentration of 0.78 mg/kg; the laboratory noted that the sample was analyzed outside of hold time. This reported concentration does not exceed applicable hazardous waste limits.

CAM 17 Metals – None of the reported metal concentrations exceeded their respective Total Threshold Limit Concentrations (TTLC), nor did any of the reported metals concentrations exceed ten times their respective Soluble Threshold Limit Concentration (STLC); further analysis of this sample for soluble concentrations is not warranted. Reported metals concentrations do not exceed applicable hazardous waste limits.

Based on the analytical data from the soil sample from boring A-22-002, it does not appear that concentrations of Volatile Organics, Purgeable Aromatics and Total Petroleum Hydrocarbons, or CAM 17 metals exceed applicable hazardous waste limits. The soil samples collected were not preserved and delivered within the specified time limit (‘hold time”). As a result, the above results are meant to be preliminary and proper testing and sampling should be performed during construction prior to excavation or disposal.

9.1 SURFACE FAULT RUPTURE
No known active faults are mapped within or through the project area. The California Geologic Survey (CGS) considers a fault to be active if it has shown movement one or more times during the Holocene period, defined as the last 11,700 years. According to the CGS, the closest active fault is the Maacama Fault about 1.8 miles east of the site. Based on this mapping we consider the potential for fault rupture at the site low.

We present a fault activity map as Figure 4.

9.2 LIQUEFACTION POTENTIAL AND SEISMICALLY INDUCED SETTLEMENT Soil liquefaction can occur when saturated, relatively loose sand and specific soft, fine-grained saturated soils are subject to ground shaking strong enough to create soil particle separation that results from increased pore pressure. This separation and subsequent pore pressure dissipation can lead to decreased soil shear strength and settlement. Liquefaction is known to occur in soils ranging from low plasticity silts to gravels. However, soils most susceptible to liquefaction are clean sands to silty sands and non-plastic silts.

To evaluate the potential for soil liquefaction to occur at the site, Crawford used the simplified procedure outlined by Youd et al. (2001)4
, the 2022 and 2017 Crawford boring data, the 2014
LACO boring data, laboratory test results, design groundwater level of elevation 565 ft, and seismicity data from our site-specific hazards analysis summarized in Section 9 above and attached in Appendix IV.

The 2014 LACO borings were not deep enough to accurately perform liquefaction analysis, however the LACO borings indicate the potential for liquefaction is considered low due to primarily encountering clayey soils. Based on the soil conditions encountered in the 2017 Crawford borings, our analysis indicates a liquefaction potential index of 2.3 categorizing the site as low risk with a liquefaction induced settlement of less than 1 inch, within the silty sand layer located about 25 ft bgs at the chlorine contact basin location. However, this sand layer was not encountered in our 2022 Crawford borings. Therefore, this sand layer is likely discontinuous across the site. Based on the encountered soil conditions, we expect the potential 4 Youd & Idriss: Liquefaction Resistance of Soils: Summary Report from the 1996 NCEER and 1998 NCEER/NSF Workshops on Evaluation of Liquefaction Resistance of Soils, April 2001 Appendix B-15 8660F10 July 12, 2023 - CONFORMED

10 for liquefaction within the proposed sludge basin and wet well to be low but may still result in up to 1 inch of settlement.

LATERAL SPREADING AND seismic SLOPE inSTABILITY
Site topography is relatively flat, with predominately clayey soils, and the liquefaction potential is low therefore, we consider lateral spreading and seismic slope instability not to be a concern at this site.
10 CONCLUSIONS AND RECOMMENDATIONS
We conclude that the site is suitable from a Geotechnical standpoint for the proposed improvements. Key Geotechnical considerations include groundwater near the base of the basin excavation (which may cause difficult construction conditions), presence of soft deleterious materials (i.e. sludge) within the basin, and the presence of saturated soils.

10.1 GRADING
We understand that the WWTP is seeking design alternatives for both concrete liner and plastic liner systems. The grading recommendations below should provide adequate support for both liner alternatives. Excessively soft sediments should be prepared following the recommendations below, regardless of liner type selection.

10.1.1 ORIGINAL GROUND & SUBGRADE PREPARATION
Prior to site grading, clear the site to remove vegetation, debris, unneeded utilities, and other deleterious materials. Process and compact the exposed subgrade in new structure and/or fill areas as follows:
• Scarify the subgrade to a depth of approximately 10 inches. • Moisture condition subgrade soil to at least 2% over optimum moisture content and compact to a minimum 90% relative compaction per ASTM D1557.

We encountered saturated (saturation ranging between 90 to 99%) lean clays and clayey sands near the expected bottom of excavation which will likely require drying back. Should difficult construction conditions be encountered, we recommend alternative methods of subgrade preparation. Based on the expected size of exposed subgrade, chemical treatment is likely an economic option. Alternatively, the subgrade could be replaced with fabric wrapped crushed rock and/or aggregate base with and without geosynthetics and/or geogrids could potentially provide a stable working platform.

10.1.2 EXCAVATABILITY
Based on the data collected during this and previous exploration programs, soils should be excavatable with typical grading equipment such as backhoes, excavators, and scrapers.

10.1.3 OVEREXCAVATION
The DCP tests completed within the basin and borings within the embankments indicate very soft sludge sediments to about elevation 567 ft. To reduce settlement and to create a firm, unyielding surface, the soft sediments within the existing basin should be removed within the planned lined basin area. Within the proposed lined basin area, overexcavate the near surface Appendix B-16 8660F10 July 12, 2023 - CONFORMED

DRAFT GEOTECHNICAL REPORT (Revision 2) Crawford
City of Ukiah Recycled Water Pipeline – Phase 4 Design Project File: 19-503.1 Ukiah, California February 3, 2023
11 very soft sludge sediments to elevation5 566 ft. Extend overexcavation 5 ft laterally beyond the edge of the basin bottom, this will require some reworking of the existing embankment.

10.1.4 FILL PLACEMENT & COMPACTION
Place fill in maximum 8-inch-thick loose lifts, moisture condition to at least optimum moisture content and compact to a minimum 90% relative compaction per ASTM D1557. Native materials, minus organics, debris and other deleterious materials, are suitable for engineered fill if not exceeding a maximum particle size of 4 inches. Excavated materials unsuitable for use as structural fill can be placed outside the structure limits, or disposed off-site.

10.1.5 IMPORT FILL
Import fill should be free of deleterious debris and meet the following requirements:
• Plasticity Index of less than 15
• Organic content of less than 2%
• Sieve Size Percentage Passing
If imported soil is required for construction, Crawford must review and approve the soils for use prior to transport to the site.

10.1.6 OVER-OPTIMUM SOIL MOISTURE
Excessively over-optimum (wet) soil conditions can make proper compaction difficult or impossible. Due to the shallow groundwater at the site wet soil will likely be encountered during construction. In general, wet soil can be mitigated by:
• Discing the soil during prolonged periods of dry weather, • Overexcavating and replacing with drier material,
• Stabilizing using aggregate and/or stabilization fabric or grid.

Crawford should observe the conditions and provide more specific mitigation recommendations during construction.

10.1.7 BENCHING
Bench fill into the existing embankment at a minimum of one foot horizontally for every one foot of fill placed, or as necessary to remove loose material and provide proper compaction along the zone of transition.

10.2 BASIN
5 This elevation is estimated based on the provided topographic survey and limited subsurface exploration information. Crawford must observe the bottom of the excavation to confirm the presence of firm, unyielding native materials prior to placing fill, rebar or concrete.

12 Based on our conversations with the City and Carollo, the planned finished grade for the bottom of the basin is elevation 570 ft. Our DCP tests completed within the existing basin area indicate the very soft sludge materials extend to about elevation 566.5 ft to 567.5 ft (about 5.5 to 6.5 ft bgs). To improve support and reduce settlement, the very soft sludge materials within the existing basin should be removed to about elevation 567 ft (See Section 10.1.3), and replaced with engineered fill or the basin bottom be lowered to achieve support within the more competent native soil below an elevation of 567 ft. Following the overexcavation of the very soft sludge sediments, the exposed subgrade at about elevation 567 ft should be scarified, moisture conditioned and compacted per Section 10.1. The designer should consider the potential for buoyancy forces when designing the bottom of the basin elevation.

10.2.1 FOUNDATION DESIGN PARAMETERS
Support for the proposed reconstructed sludge basin can achieve support for the foundation elements in compacted engineered fill or firm processed native soils below an elevation of 567 ft.

Use a modulus of subgrade reaction of 15 k/ft3 (corresponds to an allowable 1,250 psf for 1 inch of settlement). The proposed sludge basin is expected to settle on the order of 1 inch with a differential settlement of about ½ inch over a distance of about 50 ft. We expect this settlement to occur during construction.

Resistance to lateral loads (including those due to wind or seismic forces) may be determined using a coefficient of friction of 0.40 between the bottom of cast-in-place concrete foundations and the underlying soils. Lateral resistance for foundations is also available from passive soil pressure acting against the vertical face of the footings and the structure. The allowable passive pressures available may be taken as equivalent to pressures exerted by fluids weighing 220 psf per foot of embedment depth, up to a maximum of 2,000 psf. The passive pressure is only applicable if the retained earth is allowed to strain at least 0.02H.

These two modes of resistance can be combined; however, since horizontal movement is required to mobilize passive resistance, decrease the passive pressure by one-half if both friction and passive pressures are used.

Clean foundation excavations of debris and loose soil/rock prior to placing structural concrete.

Slope the ground surface away from the structures to direct surface water away from the facility.

10.2.2 BUOYANCY RESISTANCE
If buoyancy uplift will be a design consideration, buoyancy forces can be counter balanced using thickened slabs or pressure relief valves.

10.3 WET WELL

10.3.1 FOUNDATION DESIGN PARAMETERS
We understand that the wet well is planned to be supported on a mat foundation between elevations 567 ft to 568 ft. Based on information from our A-22-001 boring, loose clayey sand was encountered to an elevation of 568 ft. Provided the cast-in-place structure achieves uniform support within the underlying loose clayey sands at about elevation 568 ft, a modulus of subgrade reaction of 18 k/ft3 (corresponds to an allowable 1,500 psf for 1 inch of settlement) can Appendix B-18 8660F10 July 12, 2023 - CONFORMED

DRAFT GEOTECHNICAL REPORT (Revision 2) Crawford
City of Ukiah Recycled Water Pipeline – Phase 4 Design Project File: 19-503.1 Ukiah, California February 3, 2023
13 be used for design. Total and differential foundation settlement is expected to be less than 1 inch and ½ inch, respectively.

Lateral forces may be resisted by friction developed between the base of the footing and the underlying soil. Use a coefficient of friction of 0.45 for concrete cast against soil to resist sliding.

Additional lateral resistance may be provided by assuming a passive pressure based on an equivalent fluid weight of 270 pcf. The passive capacity reduces to an equivalent fluid weight of 150 pcf during a seismic event. In designing the structure to resist lateral loads, the upper 12 inches of soil should be ignored.

Clean foundation excavations of debris and loose soil/rock prior to placing structural concrete.

Slope the ground surface away from the structures to direct surface water away from the facility.

10.3.2 BUOYANCY RESISTANCE
We expect buoyancy uplift will not be a design consideration for the wet well. However, buoyancy forces can be counter balanced using thickened slabs or base extensions. If base extensions are used, uplift resistance is provided by the effective unit weight of the soil column directly above the base extension and wedge of soil extending outward and upward at a rate of 1:2 (H:V) from the edge of the base extension. Assuming an effective unit weight of 58 pcf for base extension uplift resistance below groundwater.

10.3.3 LATERAL EARTH PRESSURES
Use the equivalent fluid weights (EFWs) shown in the table below for design of permanent structures. We assume in-place native materials with level backfill conditions.

The EFW values above were calculated using an average unit weight of approximately 125 pcf (63 pcf below groundwater) and an angle of internal friction (𝝓) of 28°. Include full hydrostatic pressure (buoyant + hydrostatic) for walls designed to be in services below the water table.

For static design, apply the resultant of the static at-rest earth pressure at a depth of 0.33H from the base of the wall where H equals the wall height. The at-rest earth pressure does not include a factor of safety.

We estimate the EFW for seismic loading using the Mononabe-Okabe equation. Apply the additional seismic pressures separately at a depth 0.5H from the base of the wall, where H equals the wall height. For seismic design, reduce the allowable passive pressure from 270 pcf to 150 pcf. We provided a general pressure diagram below.

10.4 CONSTRUCTION CONSIDERATIONS

10.4.1 SHORING/TEMPORARY SLOPES
The contractor is responsible for the safety of all temporary excavations and must provide trench sloping and shoring design/construction in accordance with current CalOSHA requirements. In general, we encountered OSHA Type C soils at the site.

If temporary slopes are used in lieu of shoring, they must comply with OSHA standards.

10.4.2 DEWATERING
Based on the observed groundwater levels during our current and previous subsurface explorations and discussions with the WWTP personnel (see Section 5.3), groundwater was observed as high as elevation 565 ft. Therefore, groundwater may adversely affect the project Appendix B-20 8660F10 July 12, 2023 - CONFORMED

DRAFT GEOTECHNICAL REPORT (Revision 2) Crawford
City of Ukiah Recycled Water Pipeline – Phase 4 Design Project File: 19-503.1 Ukiah, California February 3, 2023
15 during construction. The contractor will be responsible for designing and implementing a dewatering system to meet the requirements of the project. Dewatering operations will need to draw the groundwater down to a minimum of 3 ft below the planned excavation during construction.
11 RISK MANAGEMENT
Our experience and that of our profession clearly indicates that the risks of costly design, construction, and maintenance problems can be significantly lowered by retaining the Geotechnical Engineer of Record to provide additional services during design and construction.

For this project, Crawford should be retained as the Geotechnical Engineer of Record to:
• Review and provide comments on the civil plans and specifications prior to construction. • Observe foundation excavations.
• Update this report if design changes occur, 2 years or more lapse between this report and construction, and/or site conditions have changed.

If Crawford is not retained to perform the above applicable services, we are not responsible for any other party’s interpretation of our report, and subsequent addendums, letters, and discussions.
12 LIMITATIONS
Crawford performed services in accordance with generally accepted geotechnical engineering principles and practices currently used in this area. Do not use this report for different locations and/or projects without the written consent of Crawford. Where referenced, we used ASTM or Caltrans standards as a general (not strict) guideline only.

Crawford based this report on the current site conditions. We assumed the soil and groundwater conditions are representative of the subsurface conditions on the site. Actual conditions between explorations and other data points could be different.

Our scope did not include evaluation of on-site hazardous materials.

Logs of our explorations are presented in Appendix A. The lines designating the interface between soil types are approximate. The transition between soil types may be abrupt or gradual. Our recommendations are based on the final logs, which represent our interpretation of the field logs and general knowledge of the site and geological conditions.

Modern design and construction are complex, with many regulatory sources/restrictions, involved parties, construction alternatives, etc. It is common to experience changes and delays.

The owner should set aside a reasonable contingency fund based on complexities and cost estimates to cover changes and delays.
