* STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results in 3 days from sample submission).

NOTES:
- MAI assumes that all material present in the provided sampling container is considered part of the sample - MAI does not exclude any material from the sample prior to sample preparation unless requested in writing by the client.

U** = An unpreserved container was received for a method that suggests a preservation in order to extend hold time for analysis.

WHEN EXISTING TREE ROOTS ARE ENCOUNTERED DURING THE COURSE OF TRENCHING, THE CONTRACTOR SHALL PREVENT THE TREE ROOTS FROM DESICCATION (DRYING OUT), BY APPLICATION OF A SEALING AGENT AND BY MINIMIZING THE AMOUNT OF TIME THAT TREE ROOTS ARE EXPOSED. TREE ROOTS SHALL ONLY BE EXPOSED WHEN TEMPERATURES ARE ANTICIPATED TO BE ABOVE FORTY DEGREES FAHRENHEIT AND BELOW 90 DEGREES FAHRENHEIT AND SHALL NOT REMAIN EXPOSED LONGER THAN 12 HOURS. IN THE EVENT THAT TRENCHES WITHIN TREE ROOT ZONES CANNOT BE BACKFILLED WITHIN 12 HOURS, THE CONTRACTOR SHALL COVER EXPOSED ROOTS WITH BURLAP AND MAINTAIN MOISTURE BY APPLICATION OF WATER TO MOISTEN BURLAP UNTIL TRENCHES CAN BE BACKFILLED. 6. UNDERGROUND FACILITIES AND TRENCHES, (e.g., UTILITY SERVICES, SANITARY SEWER, OR STORM DRAINAGE LINES) SHALL BE CONSOLIDATED, TO THE EXTENT FEASIBLE, AND LOCATED TO MINIMIZE IMPACTS UPON TREE ROOT SYSTEMS. ANY TRENCHING OR UNDERGROUND WORK SHOULD BE LOCATED OUTSIDE OF THE TREE DRIPLINE TO THE FULLEST EXTENT FEASIBLE.

4. Resolution Grace Orchard Energy Center Third Phase Agreement Summary: Council will consider adopting a Resolution to enter into a Third Phase Agreement for Renewable Power Purchase Agreement with Grace Orchard Energy Center, LLC.

Background: Twenty years ago, when California launched the Renewables Portfolio Standard (RPS) program, renewable energy sources represented a modest fraction of the state’s electricity consumption. The latest data from 2022 reveals a significant milestone: over 39 percent of California’s retail electricity sales now stem from RPS-certified renewables. When combined with significant contributions from large hydroelectric and nuclear power sources, a remarkable 61 percent of our state’s retail electricity sales derive from zerocarbon, clean generation sources. See Attachment 1 for a graph detailing California's Progress Toward 100% Clean Electricity.

California continues to make substantial strides towards achieving some of the most ambitious clean energy objectives nationwide. Senate Bill 100, enacted in 2018, established a renewable energy target of 60 percent by 2030, with a longer-term vision of powering 100 percent of California’s retail sales and state loads using RPS-certified renewable and zero-carbon energy by 2045. Recent legislative updates have further reinforced the state's commitment with new interim targets: 90 percent by 2035 and 95 percent by 2040.

The City of Ukiah Electric Utility is dedicated to increasing its supply of energy sourced from eligible renewable and carbon-free resources to comply with the California Renewable Energy Resources Act. Currently, the City's energy mix includes eligible renewable power from geothermal, small hydro, and solar. Large hydro, which is classified as carbon free, but not eligible renewable, is a large portion of the City's portfolio. The City's current portfolio boasts between 40-50% eligible renewable and 50-80% carbon free, depending on how much hydro production is achieved. Note that these numbers are based on gross energy procured through co-ownership of plants and long-term contracts, but doesn't take into account the sale of Renewable Energy Credits, which the Utility often participates in. In order to achieve 60% eligible renewable by 2030, the Utility continuously reviews projects that are economically and logistically feasible. As a member of Northern California Power Agency (NCPA), the City has a broader range of opportunities for projects where the risk can be shared with other municipal utilities.

Discussion: Northern California Power Agency, acting on behalf of its members, issued a Request for Proposals for renewable energy resources, carbon-free resources and energy storage solutions. Several

offers were received and analyzed. Grace Orchard Energy Center, LLC submitted a competitive, energy-only project.

Grace Orchard Energy Center, LLC (Grace) has agreed to sell energy, capacity rights, and associated environmental attributes from a 50 MW solar photovoltaic facility in Riverside County, California, to NCPA, on behalf of the City of Ukiah and other participating NCPA members. The terms are outlined in the Power Purchase Agreement (PPA) between Grace and NCPA (see Attachment 2). The City's portion of the project is 3MW and the term of the PPA is 20 years with a guaranteed commercial operation date of December 1, 2027. During the term of the PPA, NCPA will schedule and dispatch Grace, and Grace Orchard Energy Center LLC, will own, operate and maintain the facility.

The attached PPA is redacted due to a non-disclosure agreement between NCPA and Grace, and Grace's ongoing negotiations with other parties. However, based on the agreement details, the anticipated annual output for Ukiah would be 8,521 MWh, at a total cost of $362,256 per year. In the first year, the energy delivery projection is 8,816 MWh at a cost of $374,787. These values, along with other project aspects, stood out among the proposals as a very competitive project and will provide some of the lowest cost energy in the City's current portfolio.

To enable NCPA to enter into the PPA on behalf of the City of Ukiah and other participating members (individually called "Participants" and collectively "Participants"), the Participants shall enter into a Third Phase Agreement (Attachment 3) that provides everything necessary for NCPA to fulfill its obligations under the PPA.

This includes enabling and obligating the Participants to receive and pay for the electric capacity and energy, as well as reimbursing NCPA for all related costs. This is all in accordance with the terms and conditions of the Amended and Restated Facilities Agreement executed in 2014 between NCPA and the City of Ukiah. The Third Phase Agreement outlines the rights and responsibilities of NCPA and the Participants for managing the PPA. It requires each Participant to pay its share of all project, administrative services, scheduling coordination, and any other costs related to the PPA, based on their Project Participation Percentage.

Upon full execution of the Third Phase Agreement, NCPA will be authorized to enter into the PPA on behalf of the Participants, and such PPA shall be deemed an NCPA Project by the NCPA Commission pursuant to the Amended and Restated Facilities Agreement.

Participating in this project will boost the City's eligible renewable energy by approximately 8%, bringing us even closer to the City's goals for a greener future!

WHEREAS, Seller desires to sell, and Buyer desires to purchase, on the terms and conditions set forth in this Agreement, the Product;
NOW THEREFORE, in consideration of the mutual covenants and agreements herein contained, and for other good and valuable consideration, the sufficiency and adequacy of which are hereby acknowledged, the Parties agree to the following:

ARTICLE 1

DEFINITIONS

1.1 Contract Definitions. The following terms, when used herein with initial capitalization, shall have the meanings set forth below:
“AASMTC AD/CVD Case” means the filing of, and any proceedings, rulemakings, orders, determinations, tariffs, or duties related to, any of the Petitions for the Imposition of Antidumping and Countervailing Duties, filed on or around April 24, 2024 by the American Alliance for Solar Manufacturing Trade Committee, concerning Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled into Modules, from Cambodia, Malaysia, Thailand, and Vietnam, in any of the DOC dockets A-555-003, A-557-830, A-549-851, A-552-841, C-555-004, C-557-831, C-549-852, or C-552-842

2 “Adjusted Energy Production” has the meaning set forth in Exhibit G. “Affiliate” means, with respect to any Person, each Person that directly or indirectly controls, is controlled by, or is under common control with such designated Person. For purposes of this definition and the definition of “Permitted Transfer” and “Permitted Transferee”, “control” (including, with correlative meanings, the terms “controlled by”, and “under common control with”), as used with respect to any Person, shall mean (a) the direct or indirect right to cast at least fifty percent (50%) of the votes exercisable at an annual general meeting (or its equivalent) of such Person or, if there are no such rights, ownership of at least fifty percent (50%) of the equity or other ownership interest in such Person, or (b) the right to direct the policies or operations of such Person. Notwithstanding the foregoing, with respect to Seller, Affiliate shall include any investment funds or publicly-traded vehicles for the ownership of operating power generation, storage, or transmission assets (such as a “yield co”) controlled by Seller, NextEra Energy, Inc. or an Affiliate of NextEra Energy, Inc., NextEra Energy Partners, LP (“NEP”), NextEra Energy Operating Partners, LP (“NEOP”), and NextEra Energy Capital Holdings, Inc. (“NEECH”), and their respective direct or indirect subsidiaries.
“After-Tax Basis” means, with respect to any payment received, or deemed to have been received, by any Person, the amount of such payment (the “Base Payment”), supplemented by a further payment (the “Additional Payment”) to such Person so that the sum of the Base Payment plus the Additional Payment will be equal to the Base Payment, after deduction of the amount of all taxes required to be paid by such Person in respect of the receipt or accrual of the Base Payment and the Additional Payment (taking into account any current or previous credits or deductions arising from the underlying event giving rise to the payment, the Base Payment and the Additional Payment). Such calculations shall be made on the assumption that the recipient is subject to Federal income taxation at the statutory rate applicable to corporations under subchapter C of the Internal Revenue Code of 1986, as amended, and subject to the highest state and local income tax rate then in effect for corporations in the states in which the Person is subject to taxation during the applicable fiscal year, and shall take into account the deductibility, if applicable (for Federal income tax purposes), of state and local income taxes.
“Agreement” has the meaning set forth in the Preamble and includes any Exhibits, schedules and any written supplements hereto, the Cover Sheet, and any designated collateral, credit support or similar arrangement between the Parties. “Approved Forecast Vendor” means (i) CAISO, or in the event the CAISO no longer provides a forecast of Facility Energy for the Facility under the EIRP, then (ii) Seller or a Seller Affiliate, or if not Seller or a Seller Affiliate, a vendor selected by Seller for the purposes of providing or verifying the forecasts under Section 4.3(d) reasonably acceptable to Buyer, with such acceptance not to be unreasonably withheld, conditioned or delayed. “Auxin Anti-Circumvention Proceeding” means the DOC’s anti-circumvention investigation and proceeding concerning Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled into Modules, from the People's Republic of China, Petition filed February 8, 2022 by Auxin Solar, Inc. in four separate DOC dockets: A-570-979 Malaysia; Thailand; Cambodia; and Vietnam.

Page 1298 of 1534 ends

3 “Available Generating Capacity” means the capacity of the Facility, expressed in whole MWs, that is mechanically available to generate Energy. “Bankrupt” means with respect to any entity, such entity that (a) files a petition or otherwise commences, authorizes or acquiesces in the commencement of a proceeding or cause of action under any bankruptcy, insolvency, reorganization or similar Law, (b) has any such petition filed or commenced against it which remains unstayed or undismissed for a period of ninety (90) days, (c) makes an assignment or any general arrangement for the benefit of creditors, (d) otherwise becomes bankrupt or insolvent (however evidenced), (e) has a liquidator, administrator, receiver, trustee, conservator or similar official appointed with respect to it or any substantial portion of its property or assets, or (f) is generally unable to pay its debts as they fall due. “Business Day” means any day except a Saturday, Sunday, or a Federal Reserve Bank holiday in California. A Business Day begins at 8:00 a.m. and ends at 5:00 p.m. local time for the Party sending a Notice, or payment, or performing a specified action. “Buyer” has the meaning set forth in the Cover Sheet.
“Buyer Bid Curtailment” means the occurrence of both of the following:
(a) the CAISO provides notice to a Party or the Scheduling Coordinator for the Facility, requiring the Party to deliver less Facility Energy than the full amount of Energy forecasted in accordance with Section 4.3(d) to be produced from the Facility for a period of time; and (b) for the same time period as referenced in (a), the notice referenced in (a) results from Buyer or the SC for the Facility, as the result of a Buyer instruction or lack of instruction to the SC:
(i) not having submitted a Self-Schedule or Energy Supply Bid for the MW subject to the reduction;
(ii) having submitted an Energy Supply Bid and the MW subject to the reduction were not awarded a schedule with respect to the Energy Supply Bid; or (iii) having submitted a Self-Schedule for less than the full amount of Energy forecasted to be generated by or delivered from the Facility in accordance with Section 4.3(d).

If the Facility is subject to a Planned Outage, Forced Facility Outage, Force Majeure Event and/or a Curtailment Period during the same time period as referenced in (a), then the calculation of Deemed Delivered Energy during such period shall not include any Facility Energy that was not generated due to such Planned Outage, Forced Facility Outage, Force Majeure Event, or Curtailment Order. For avoidance of doubt, if a Buyer Bid Curtailment and a CAISO system-wide overgeneration Curtailment Order occur in the same Settlement Interval or Settlement Period, the curtailment shall be treated as:
