DECOMMISSIONING AND BUDGET AMENDMENT
RECOMMENDATION: Adopt Resolution Approving a Professional Services Agreement with EKI Environment & Water, Inc., for
Monitoring Well Network Abandonment for CIP RW
24- 16 Recycled Water System Decommissioning and
Budget Amendment
SUMMARY:

At their June 2023 board meeting, the Central Valley Regional Water Quality Control Board ( CVRWQCB) approved rescission of the Waste Discharge Requirements ( WDRs) and amendment to the National Pollutant Discharge Elimination System ( NPDES) permit to discharge effluent from the Consolidated Treatment Facility ( CTF) to the San Joaquin River. Previously, the CVRWQCB issued a letter dated March 27, 2023, that provided conditional approval of a technical memorandum submitted by the City for the closure activities associated with WDR rescission, which designated the City as the responsible party for the proper abandonment of 67 monitoring wells associated with the WDR monitoring well network.

At the request of staff, EKI Environment & Water, Inc. ( EKI) provided a proposal for professional services to assist the City with the monitoring well abandonment. EKI is uniquely qualified to provide these services based on approximately twenty years of experience assisting the City with groundwater monitoring and reporting for the CTF and former Crossroads WDRs. Approval of the proposed Professional Services Agreement ( PSA) with EKI in the amount of $487, 000 is requested to assist the City with the monitoring well network abandonment.

The City has insufficient funds for these costs under CIP RW 24- 16 Recycled Water System Decommissioning in the approved budget for Fiscal Years 2023- 2024 and 2024- 2025. Additional funds in the amount of $ 100, 000 is requested as a contingency for the monitoring well removal, and to cover additional costs associated with the recycled water system decommissioning. Staff is requesting that Council approve a budget amendment allocating $ 455, 500 from the CTF Fund 6110 for the City' s cost share and approve a revenue adjustment increase of $ 131, 500 to recognize the revenue received from the responsible parties.

APPROVE PSA WITH EKI ENVIRONMENT & WATER, INC., FOR MONITORING WELL NETWORK ABANDONMENT FOR CIP RW 24- 16 RECYCLED WATER

SYSTEM DECOMMISSIONING AND BUDGET AMENDMENT
BACKGROUND:

At the June 2023 CVRWQB board meeting, the CVRWQB approved rescission of the WDRs and an amendment to the NPDES permit to discharge effluent from the CTF to the San Joaquin River. Previously the CVRWQCB had issued a letter on March 27, 2023, that provided conditional approval of a technical memorandum submitted by the City on the closure activities associated with WDR rescission, which designated the City as the responsible party for the proper abandonment of 67 monitoring wells associated with WDRs monitoring well network. Of the 67 wells, 34 wells are currently located on private property and 33 wells are currently located on City- owned land.

In some instances, the developer of the parcel in which the well is located has been named as the responsible party to fund the cost of well abandonment.

At the request of staff, EKI Environment & Water, Inc., ( EKI) provided a proposal for professional services for assisting the City with the monitoring well abandonment.

EKI' s scope and fee proposal includes a breakdown of costs for wells associated with the City and developer funding sources as follows:

Fundin Source Cost Estimate
Cit 355, 500
Richland 27, 700
River Islands/ Califia 73, 400
Sa brook 11, 500
Scannell Pro erties # 478, LLC 18, 900
TOTAL: 487, 000
Staff requests City Council approve a PSA with EKI to assist the City with abandonment of 67 monitoring wells associated with the CTF WDRs. In addition, staff requests approval of additional budget in the amount of $ 100, 000 to provide a contingency for the monitoring well abandonment, and to cover additional costs associated with the recycled water decommissioning such as ordering title reports, preparation of grant deeds, easements and filing fees.

REASON FOR RECOMMENDATION:

EKI is uniquely qualified to provide these services based on approximately twenty years of experience assisting the City with groundwater monitoring services associated with the CTF and former Crossroads WDRs.

The professional services to be provided by EKI under this proposed agreement will meet the regulatory requirements for proper removal of the monitoring well network pursuant to the conditionally approved closure plan associated with the WDRs rescission. Removal of these monitoring wells under will help expedite returning lands back to developers that have a right of reverter for parcels with ponds and sprayfields that are planned to be decommissioned.

Subject: Scope of Work and Budget- Monitoring Well Network Abandonment City of Lathrop
EKI C3- 130)
Dear Mr. Gibson:

EKI Environment& Water, Inc.( EKI) is pleased to present this scope of work( SOW) and budget for assisting the City of Lathrop( City) with abandonment of 67 monitoring wells associated with the City' s Consolidated Treatment Facility ( CTF) Waste Discharge Requirements ( WDR) Order No. R5- 2018- 023. As the City has acquired a National Pollutant Discharge Elimination System( NPDES) permit[ RS- 2022- 0004( CA0085359)] 1 from the Central Valley Regional Water Quality Control Board( RWQCB) to discharge effluent from the CTF to the San Joaquin River instead of land application areas covered under the WDR, the monitoring wells are no longer required. Conditional approval for closure of various CTF site features was granted in a March 2023 recission letter from the RWQCB( Recission Letter). The RWQCB plans to rescind the CTF WDR during the RWQCB' s June 2023 Board Meeting. z

BACKGROUND
As shown in Figure 1, there are 67 existing wells associated with compliance monitoring in the Monitoring and Reporting Program Order No. R5- 2016- 0028- 03 ( MRP) that the City intends to abandon ( only wells MWM- 24 and MWR- 25 will remain in place and used for Sustainable Groundwater Management Act SGMA] compliance monitoring). As the City will cease all future effluent land disposal operations and will use recycled water only for beneficial uses regulated under the Recycled Water General Order WQ 2016- 0068- DDW( General Order), the monitoring well network is no longer needed.

Of the 67 wells, 34 wells are currently located on private property and 33 wells are currently located on City- owned land ( see Table 1). In some instances, the developer of the parcel in which the well is located has been named responsible to fund the cost of well abandonment( see Table 1, " Funding Source"). The City is responsible for all monitoring well abandonment3 in accordance with California Department of Water Resources( DWR) standards for the destruction of groundwater wells. 4 The City will work with the 1 Adopted 17 February 2022.

landowners to gain access to properly abandon the wells. In the event of non- responsive private property owners, the City will notify the RWQCB and San loaquin County ( SJC) and work with SJC Environmental Health Department( EHD) and the RWQCB for follow- up and/ or enforcement actions.

The abandonments of the monitoring wells must be conducted in accordance with the 2016 Monitoring Well Abandonment Workplan dated 25 January 2016(" Workplan"), which was conditionally approved by the RWQCB on 10 May 2016. Furthermore, based on historical and current land use and groundwater monitoring data, no hazardous constituents are expected at the drilling locations. As such, equipment decontamination procedures and the general health and safety plan outlined in the 2016 Monitoring Well Abandonment Workplan will be followed.

Prior to well abandonment, the City will file applicable well abandonment permits with the S1C EHD.

Following well abandonment, the City will file well destruction reports with the DWR.

SCOPE OF WORK
The Scope of Work provided below separates the monitoring network abandonment into five tasks and assumes a total of four well abandonment mobilizations. Exact counts and timing of the well abandonment work will depend upon landowner responses. If more than four mobilizations are required, the level of effort and cost to complete the work will increase. Table 1 provides well- specific details and assumptions and Figure 1 shows well locations. Additionally, the following assumptions are applicable for all five tasks:

Costs associated with the C- 57 licensed driller include prevailing wage rates.

The budget estimate assumes abandonment work will be conducted in a continuous fashion requiring a total of four mobilizations and demobilizations( two for each abandonment method).

Pressure grout abandonment work is anticipated to take a total of 18 days and includes the C- 57 licensed driller crew and EKI oversight on all 18 days. Overdrilling abandonment work is anticipated to take five days and includes the C- 57 licensed driller crew and EKI oversight on all five days.

Driller costs assume all locations are truck accessible.

The City will require EKI on- site for construction oversight during well abandonments and surface completion work, as applicable. For cost estimating purposes, EKI has assumed 9- hour workdays.

EKI will provide the City with electronic copies of the DWR well completion reports.

If the schedule is delayed due to unforeseen circumstances out of EKI' s control, additional budget may be required.

Additional budget may be required if site conditions differ significantly than the budget estimate assumes, based on the November 2022 well survey, or access is hindered due to inclement weather.

Task 1— City Funded Well Abandonment
Under Task 1, EKI will plan and oversee abandonment of the 43 wells located on City and private property see Table 1).

Subtask 1. 1— Private Propertv Owner Coordination
EKI will coordinate with private property owners to obtain access for well abandonment. As shown on Table 1, there are seven known, three unknown, and one assumed but unconfirmed property owner.

Under Subtask 1. 1, EKI will prepare notifications for a maximum of 12 private property ownerss of the requirement to allow City access to properly abandon fourteen ( 14) monitoring well( s). Where current ownership has changed or is otherwise unknown, EKI will attempt to determine landowner information from Assessor Parcel Number( APN) information based on publicly available data from the County and/ or other readily available methods. Notification letters will provide EKI/ City contact information that includes a phone number and email address to submit questions. To ensure delivery, EKI will send the notification letters via email and/ or accountable mail in which delivery requires a signature and/ or read receipt.

Three wells currently do not have signed access agreements in place with the existing property owner, and two wells are assumed to have the same property owner as the access agreement on file, however access has not been coordinated since 2018. EKI will coordinate and attempt to secure access agreements for a maximum of five wells including the three wells without current access agreements.

Assumptions
EKI will provide draft notification materials for City review. Comments from the City will be addressed by EKI and the notification materials finalized for transmittal to property owners.

In the event that EKI cannot determine ownership, or the notification letter cannot be delivered, EKI will work with the City to identify appropriate next steps.

Deliverables
Well abandonment notification materials for private property owners [ up to 12 letters for 14 wells].

Access agreements for up to five wells.

Subtask 1. 2- Preparation, Permittin and Contracts
Under Subtask 1. 2, EKI will complete the necessary preparations, permitting, and contracting for the abandonment of the 43 monitoring wells. This subtask includes:

Project management such as coordination, subcontracting, planning, and communication between the City, licensed driller, and traffic control specialists.

Update Site Health and Safety Plan.

Direct B. A.T.S. Traffic Solutions to obtain encroachment permits from the City of Lathrop, as needed, for up to 19 wells located within or adjacent to the street right-of-way or within public parks ( see Table 1).
5 Property owners that are unknown or uncertain have conservatively been counted as individual private property owners.

Obtain 43 monitoring well destruction permits from the SJC EHD.

Coordinate with a California- certified analytical laboratory regarding analytical needs, turnaround times, courier scheduling, and sample containers, as appropriate.

Assumptions
Each encroachment permit will require five hours of B. A.T.S. Traffic Solutions time to prepare, and the Ciry' s$ 120 encroachment permit fee.

Permits and traffic control plans for all wells will be developed and obtained simultaneously.

Monitoring wells MWM- S, MWM- 15, MWM- 17 will require an encroachment permit but not a traffic control plan.

Other wells located on City property that are not within or adjacent to the street right-of-way or within public parks, ( see Table 1) will not require an encroachment permit.

Deliverables
Up to 19 Encroachment permits
Up to 16 Traffic Control plans

For 10 wells located in the street or paved parking lot and one well located in the sidewalk, direct contractor to apply hot asphalt patch and concrete patch, respectively, in accordance with Encroachment Permit.

Sampling and laboratory analysis of generated wastes for disposal, when appropriate.

Greg Gibson environment
City of Lathrop water
31 May 2023

Assumptions
The City will be responsible for towing vehicles that interfere with well abandonment.

Traffic control is dependent upon the site- specific traffic control plans to be developed under Subtask 1. 2, and therefore the budget assumes a two- person crew with two trucks for required traffic control ( during both abandonment and surface completion) and three weeks of traffic control rental items.

The City will be responsible for removal and repair of all fencing that interfere with well abandonment activities.

To the extent possible, soil cuttings and groundwater produced during drilling and grouting operations will be spread at the site. Where spreading is not feasible ( e. g., city street), the materials will be transported to a location as directed by the City for spreading. Should it be necessary, the budget accommodates the possible need to drum, test, and haul soil cuttings and groundwater for disposal at an approved landfill. The budget assumes one composite sample per mobilization will be collected ( total of two samples), analyzed for the standard suite of constituents required for landfill disposal6, and the materials will clear all applicable standards for non- hazardous waste disposal. If the composite sample exceeds either California Soluble Threshold Limit Concentration( STLC) or Federal Toxicity Characteristic Leaching Procedure( TCLP) limits for hazardous waste characterization, there will be additional costs associated with disposal not included herein.

Two separate mobilizations will be required to apply the hot asphalt and concrete patch work.

Surface completion work is anticipated to take a total of five days, and includes the construction crew, traffic control, and EKI oversight on all five days. Surface completion will occur within 48- hours of well abandonment completion.
32 wells will have a dirt surface completion, 10 wells will have a hot asphalt patch surface completion, and one well will have a concrete patch surface completion. Asphalt patches will be no larger than 3' x 3' and up to 6" thick, with no roller or grind back needed. The concrete patch will be up to 6' x 6' and up to 6" thick with no curb or gutter work required.

This scope of work and budget does not include replacement of landscape in City parks, medians, etc. that are removed or damaged to access the wells for abandonment.

Monitoring well MW- 5 is located adjacent to privately- owned railroad tracks and will not require coordination with Union Pacific Railroad.

Subtask 1. 4— Documentation
Under Subtask 1. 4, EKI will prepare and submit 43 DWR well destruction reports to DWR and prepare a Groundwater Monitoring Well Abandonment Report for submittal to the RWQCB. This report will document the well abandonment activities, discuss any deviations from the approved Workplan, and include copies of the DWR well destruction reports.

EKI will coordinate with Confluence to mobilize to the site, set up, and begin the abandonment process for the wells. Specifically, under Subtask 5. 3 EKI will:

Mark three wells for Underground Services Alert ( USA) and submit tickets at least 72 hours but no more than two weeks prior to destruction activities.

Schedule well destruction inspections with the SJC EHD and direct driller to perform all sealing operations in the presence of the County inspector, unless directed otherwise by the County.

Oversee well abandonment by a C- 57 licensed driller via pressure grouting ( 3 wells), using methods as described in the approved Workplan.

Assumptions
No wells require traffic control plans nor traffic control during abandonment.

Soil cuttings and groundwater produced during drilling and grouting operations will be spread at the site.

All three wells will have a dirt surface completion.

Subtask 5. 2— Documentation
Under Subtask 5. 4, EKI will prepare and submit three DWR well destruction reports to DWR and prepare documentation for inclusion into the Groundwater Monitoring Well Abandonment Report for submittal to the RWQCB. This report will document the well abandonment activities, discuss any deviations from the approved Workplan, and include copies of the DWR well destruction reports.

SCHEDULE
Tasks identified above are anticipated to be conducted during the summer and fall of 2023.

Given the uncertainty in landowner responsiveness, private property owner coordination will be initiated immediately upon Notice to Proceed, and transmittal materials are anticipated to be ready for disbursement within 3- weeks. Ongoing coordination with responsive property owners will occur throughout the project duration.

For wells located in the City right- of-way or City parks, abandonment will not occur until encroachment permits and traffic control plans, as required, have been successfully procured.

Subject to C- 57 driller and B. A.T.S. Traffic Solutions availability, well abandonment activities are anticipated to be completed within 10- weeks of procuring all necessary paperwork and permitting. Well abandonment and surface completion construction work is anticipated to take 28 days, assuming adequate site conditions and no access delays. This work assumes two mobilizations per abandonment method, for a total of four well abandonment mobilizations, and two mobilizations for surface completion construction work. Surface completion will occur within 48- hours of well abandonment completion. The estimated days for well abandonment completion may vary depending upon the order of well abandonment, and wells may be re- scheduled between assumed mobilizations depending upon landowner response and coordination.

As- needed City support will last the entire project duration.

The Draft Groundwater Monitoring Well Abandonment Report will be submitted to the City within 30 days of the abandonment completion. The Final Groundwater Monitoring Well Abandonment Report will be completed and submitted to the City 10 days after receiving comments.

COMPENSATION
We propose that compensation for consulting services by EKI be on a time and expense reimbursement basis in accordance with our attached schedule of charges dated 2 January 2022. Based on the SOW described above and the budget in the attached Table 2, per well costs have been calculated and distributed among the funding sources, as shown in Table 3 and Table 1, respectively.
