COST PROPOSAL FOR TASK BIL002G

<Former Polk County Fertilizer/FDEP ERIC_13343>

< Source Removal >

1. INTRODUCTION: <DISCUSS SCOPE OF WORK, DATES >

GHD Services Inc. (GHD) submitted an Interim Source Removal Plan (ISRP) for the former Polk County Fertilizer site located in Haines City, Polk County, in August 2025. The ISRP was reviewed and approved soon by the Department. Task BIL002G includes implementation of the proposed source removal.

Subtask 1: Project Management Subtask 1 includes all tasks associated with project management of the source removal activities at the former Polk County Fertilizer site.

Subtask 2: Confirmation Soil Sampling Based on the results of the most recent soil sampling in January 2026, additional testing is recommended to finalize the excavation cut lines. Specifically, GHD recommends advancing seventeen (17) soil borings at locations shown in the supplemental soil sampling summary dated January 30, 2026. The soil borings will be advanced by hand and soil samples will be collected at the prescribed depths in accordance with the QAPP. Soil samples will be submitted to a certified laboratory for analysis for the presence of organochlorine pesticides and/or polycyclic aromatic hydrocarbons.

Upon receipt of analytical data, the summary tables and figures will be updated to evaluate cut lines. Recommendations will be provided regarding additional testing or source removal.

Subtask 3: Baseline Groundwater Sampling Prior to completing the source removal, baseline groundwater sampling is recommended.

Prior to groundwater sampling, GHD personnel will gather depth to water measurements at all available monitoring wells (6 total). Following depth to water measurements, groundwater sampling will be conducted. Groundwater sampling is recommended at 6 site monitor wells including MW-6R, MW-7R, MW-9, MW-10, MW-11, and MW-12D. Groundwater samples will be analyzed for the presence of orgaochlorine pesticides and nitrate . Groundwater sampling will be conducted in accordance with FDEP standard operating procedures.

Following groundwater sampling, monitoring wells MW-6R, MW-7R, MW-9, and MW-12D will be modified temporarily to accommodate excavation. Specifically the well pads will be removed and well casings marked.

Upon receipt of analytical data, tables and figures will be updated with the baseline results.

The results will be transmitted to FDEP with recommendations regarding proceeding with the source removal.

Subtask 4: Source Removal Upon completion of baseline sampling and DEP approval of the email recommendations, source removal activities will be conducted. The following sequence of activities is proposed for the source removal.

Complete additional soil delineation sampling

Update Health and Safety Plan;

Coordinate with Site owner;

Complete the baseline groundwater sampling event;

Submit utility clearance locate ticket;

Remove pads and manholes for wells within the proposed excavation limits;

Install temporary tracking controls and prepare the loading area on the dirt road traversing the center of the Site;

Complete excavation to a maximum depth of 6 ft bls;

Establish a working base for restoration;

Place backfill and compact as necessary;

Hydroseeding to stabilize backfill; and Replace monitoring well manholes and concrete pads.

The excavation activities will be conducted using a track-mounted excavator. The estimated quantity of soil for disposal is on the order of 1,600 tons. The soil will be excavated and loaded into trucks for off-site disposal following approval for landfill disposal.

Following excavation to depth, the area will be backfilled with clean import backfill. Clean import fill will be placed and compacted per the ISRP. The backfill will be used to bring the site to grade. The final restoration will involved demobilizing of the groundwater treatment equipment and placement of hydroseed in disturbed areas.

Subtask 5: Source Removal Monitoring During source removal activities, GHD technician will direct the excavation, screen soils, facilitate confirmation laboratory analysis, track disposal manifests, and prepare as-built drawings.

Subtask 6: Source Removal Report Upon completion of the source removal activities, a Source Removal Report (SRR) will be prepared. The SRR will detail the baseline sampling methods and results. The SRR will also detail source removal activities and results of confirmation soil and water sampling. The SRR will include recommendations for additional monitoring and/or cleanup.

Demurrage charged after one hour loading & unloading

Pricing assumes that drums/pallets are staged on a hard surface, accessible via van truck with liftgate & one driver with drum dolly or pallet jack.

Inaccessible areas (mud, heavy gravel), excessively heavy, deformed, unwieldy drums may require additional labor and equipment to assist. Fees for additional labor and equipment will be charged per EnviroServe's standard T&M rates.

The following materials are not eligible for LTL pricing and require direct or dedicated shipment to the TSDF: Cyanides, DOT Class 4.3 materials, DOT Class 1.4, 1.5 & 1.6 materials, Temperature Controlled/Self Reactive Materials, Odorant Materials (Mercaptans/Thiols), and other reactive/incompatible materials on a case by case basis. High hazardous containers (pails, drums, boxes, cylinders, etc.) will need to be assessed on a case by case basis to determine ability to be transported by EnviroServe.

Pricing for supplies (drums, pails, absorbent pads, etc.) is variable and may be adjusted without notice to account for market increases.

Terms and Conditions

The following terms and conditions apply to all materials sold and services provided by EnviroServe Inc. (“EnviroServe”) to the Client named on the signature line of this Agreement and are applicable to any subsidiary and/or affiliate of Client that EnviroServe sells materials to or provides services to on such Client’s behalf.

1. Entire and Sole Agreement.

1.1 These terms and conditions, along with any terms provided by EnviroServe in its Quotation, Proposal, or on the face sheet of this Agreement, shall constitute the entire and sole agreement (“Agreement”) between EnviroServe and Client as to the goods sold and/or services provided and shall supersede all prior oral or written agreements by and between EnviroServe and Client. These terms and conditions may not be modified, altered or canceled without the express written agreement signed by both EnviroServe and Client. In the case of any inconsistency between these terms and conditions and any other terms, conditions, or provisions, then the terms and conditions set forth herein shall expressly control. Client expressly waives all provisions contained in any correspondence or forms involved in this transaction which negate, limit, extend or conflict with the terms and conditions stated herein. Client agrees that it has not been induced to enter into this Agreement by any oral or written representation, guaranty or warranty made by EnviroServe, its employees, agents or representatives other than as expressly set forth herein or on the face sheet hereof. If any portion of this

Agreement is deemed to be illegal or unenforceable by a court of law, then the validity of the remaining portions or provision shall not be affected and shall remain in full force and effect. Notwithstanding the preceding sentence, if EnviroServe in its sole discretion determines that the absence of the eliminated provision is contrary to the original intention of the parties, then EnviroServe shall have the right to terminate the Agreement.

1.2 Client's engagement of EnviroServe represents Client's acceptance of this Agreement, which constitutes the entire understanding and supersedes any prior or subsequent communications, representations or agreements of the parties, whether oral or written, including Client's additions or different terms and conditions that may be contained in any purchase order, work order, acknowledgment form, manifest or other document referenced, incorporated, and/or provided by Client to EnviroServe, to which notice of objection is hereby given. Any terms and conditions referenced, incorporated, and/or provided by Client, and any Client additions, subtractions, or edits to the terms and conditions stated herein, are void and of no effect.

1.3 EnviroServe shall perform in accordance with generally accepted industry principles and practices, in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions.

2. Personnel and Safety.

2.1 EnviroServe's personnel endeavor to conduct field activities in such a manner as to protect themselves and others from accidents and injury.

EnviroServe's personnel use their own safety equipment (hard hat, protective clothing and eyewear, respirator, etc.) unless otherwise instructed. Client agrees to notify EnviroServe in writing before the work proceeds in the event Client is aware of a special safety need.

2.2 EnviroServe shall have the right to subcontract any or all of the work covered by the Agreement. Any assignment of this Agreement or any rights hereunder by Client without written consent of EnviroServe shall be void.

2.3 EnviroServe will perform the services as an independent contractor. For the purposes of its performance hereunder, EnviroServe is not a servant, employee or other agent of Client. EnviroServe shall have the exclusive right to determine how its work or services will be accomplished and Client shall have no right to control and shall not control or direct the details, manner or means by which EnviroServe obtains or provides services to Client.

EnviroServe may continue to offer its services to the general public. Except as may be provided for herein, neither party may enter into agreements, make commitments or incur liabilities or obligations on behalf of the other party. Nothing in this Agreement will be deemed to create an agency relationship, partnership or joint venture between EnviroServe and Client, each of which is expressly denied.

2.4 Client warrants to EnviroServe that Client has procured the requisite legal right, title, and interest necessary to provide EnviroServe legal access to the job site ("Site"). EnviroServe will take reasonable precautions to minimize any damage to the Site and adjoining properties. Client shall identify and locate the area to be serviced at the Site and shall identify and accurately mark all pipelines, utilities, and other facilities at or near the work area.

EnviroServe is not charged with knowledge of any latent, concealed, or subsurface site conditions, and shall not be liable for: (i) damage or injury to any subsurface structures (including, but not limited to, utilities, mains, pipes, tanks, and telephone cables, human remains, burial markers, archeological sites, wetlands or hazardous materials or any wastes not identified in the Agreement) or any existing subsurface conditions, or the consequences of such damage or injury, if such structures or conditions were unknown and were not identified or shown, or were incorrectly shown, in information or on plans furnished to or obtained by EnviroServe in connection with the services; (ii) concealed conditions encountered in the performance of the services; (iii) concealed or unknown conditions in an existing structure at variance with the conditions indicated by the Agreement or information furnished to or obtained by EnviroServe; or (iv) unknown subsurface physical conditions that differ materially from those ordinarily encountered. Should EnviroServe encounter such conditions, the Parties shall agree on a revised Scope of Work providing for an equitable adjustment of the price and/or time of performance to account for such unknown or changed conditions. EnviroServe’s duty to defend, indemnify and hold harmless, as provided in this Agreement and otherwise, shall not extend to any losses arising out of, resulting from, or in any way connected with, any such latent, concealed, or subsurface conditions.

2.5 Client agrees to de-energize, lock out, tag out, and ground any electrical equipment consistent with EnviroServe's schedule for services, provide utility services required for the performance of services; provide ventilation capacity, as specified, provide access to workrooms, toilet facilities, first-aid and medical facilities as available, for EnviroServe personnel; re-energize the equipment after servicing by EnviroServe. Client shall be responsible for all loss, damage, or injury to equipment that is de-energized including fuses, cutouts and switches, and shall operate its equipment before, during and after servicing in accordance with state, local and federal laws. Client acknowledges that all equipment may be affected by operating conditions other than those for which the equipment was designed. Client recognizes that equipment is subject to failure at any point and failures may be brought about prematurely by excessive heating, overloading, shock loading, transient voltage surges, among other causes, all of which are within the exclusive control of Client. Client is aware that operating conditions, including examples stated above which contribute to the failure of equipment may exist prior, during and subsequent to the performance of the services. Client acknowledges that the operating conditions are under its exclusive control and that

02/23/2026 04:27 PM PAGE 5 OF 10

Client has elected to service its equipment, such choice having been made with full knowledge of the factors outlined above and after evaluation of the processing equipment, techniques, and procedures to be used by EnviroServe. Client assumes the risk of damage or loss of equipment from any cause whatsoever.

2.6 Client, its subsidiaries, affiliates or employees shall not solicit or otherwise offer employment to EnviroServe's employees, or former EnviroServe employees who had been employed by EnviroServe on the date of this Agreement, or EnviroServe’s subcontractors during the time period of this agreement and for a period of five (5) years following the date on which EnviroServe last performs services under this Agreement unless there is mutual written consent in regards to a particular employee, former employee or subcontractor. Furthermore, Client will not, nor will it permit any of its directors, officers, employees, representatives, or agents to solicit, directly or indirectly, the business of, perform services, or provide materials to, or otherwise participate in discussions or negotiations with any vendor, supplier, or customer of Client that is introduced by EnviroServe to Client for a period of five (5) years following the date on which EnviroServe last performed services under this Agreement.

3. Confidential Information/Trade Secrets.

3.1 During the conduct of specific assignments, either party may obtain, directly or indirectly, Confidential Information proprietary to the other.

Accordingly, each party agrees to maintain, as secret and confidential, all of the other party’s Confidential Information, and agrees to not disclose it to others or use it without specific authorization from the party which provided the Confidential Information, except as may be required to perform its obligations under this Agreement or as required by law or other legal process. Media requests for information will be directed to Client or its designated representative.

(b) was rightfully available to a party on a non-confidential basis prior to its disclosure by one party to the other; (c) becomes available to a party from a source other than the other, provided that the source is not (to the knowledge of the receiving party) bound by a contractual, fiduciary obligation or other obligation of secrecy; or (d) is developed by a party independent of any Confidential Information of the other. At all times, the Parties agree not to disclose to any person or entity any Confidential Information of the other. Furthermore, each party retains exclusive ownership of all of its Confidential

Information, and the receiving party obtains no license or other rights thereto. The Parties hereby agree that if the other breaches this section, it shall incur irreparable injury and harm and money damages would be an insufficient remedy, and as such, and in addition to all other remedies, the aggrieved party shall be entitled to seek injunctive relief restraining the other from further breach of this section.

3.3 Each party may: (a) disclose Confidential Information to its attorneys, accountants, other professional advisors, and permitted subcontractors, to the extent, necessary to perform or enforce any obligation under this Agreement; (b) retain back-up copies of the Confidential Information in its computer systems to the extent that routine computer back-up procedures create copies in the associated back-up, archival, or cloud based computer storage system, and

4. Waste.

4.1 Hazardous and/or non-hazardous materials and waste(s) (“Waste”) may be created, handled, stored, transported, and/or disposed of during the performance of services by EnviroServe. Client agrees that Client at all times is the generator of the Waste, and retains sole responsibility, title and ownership of the Waste, from the time of original creation of the Waste until it is received and accepted by the final treatment/disposal facility, including during any times in which Client receives assistance, handling, transportation, storage or other services from EnviroServe.

4.2 Nothing contained in this Agreement shall be construed or interpreted as requiring or deeming EnviroServe to assume the status of generator as that term appears within the Resource Conservation and Recovery Act, 42 USC Section 6901 et seq, as amended or within any state statute governing the generation of waste. Client agrees that EnviroServe shall not take ownership of, or be deemed a generator of, the Waste, or of any soils, containers, hazardous materials, hazardous waste, or other items handled, collected, transported and/or disposed of pursuant to this Agreement.

Client, or which is used by EnviroServe or left on site by EnviroServe in connection with the goods or services provided under this Agreement. Without limiting the foregoing, in no event shall EnviroServe be liable for unknown site conditions, or for release, discharge, spillages or disposal from equipment, realty or facilities which are not then in EnviroServe’s actual custody, possession and control, and Client agrees to indemnify and hold EnviroServe harmless with respect to such release, discharge, spillages or disposal.

4.5 Client agrees to be responsible to select and approve the method of treatment / disposal, and the treatment / disposal facility(s) for the Waste.

Client agrees to provide EnviroServe with properly executed Waste Profile Sheet(s), which accurately and completely describes each type of Waste material, within 24 hours of the creation of the Waste. In the event that executed Waste profiles are not received by EnviroServe within this 24-hour time period, Client agrees to pay EnviroServe a daily Waste Handling fee as listed in the Proposal Rate Schedule (subject to a $1,000 minimum charge), for each day thereafter, until the executed Waste Profile Sheet(s) are received by EnviroServe.

4.6 Waste Profile Sheets provided by Client shall include: Client’s name; identification of Generator of the Waste; date; type of Waste material (e.g., 02/23/2026 04:27 PM PAGE 6 OF 10 spent acids); source of waste material (e.g., electroplating vat); form of waste material (e.g., liquid); shipping unit (e.g., 55 gallon metal drum);

characteristics, including type, source, and toxic constituents; EPA waste codes; and a signature of an authorized representative of Client. Client represents that all information on its Waste Profile Sheet(s) is accurate.

(a) EnviroServe may provide Client with partially completed waste profile(s) for review and signature. Client agrees to accept sole responsibility to review and correct this information, as necessary.

(b) Client agrees that EnviroServe is under no obligation to transport any Waste until Client has provided EnviroServe with properly completed Waste

Profile Sheet(s).

EnviroServe does not accept title, generator responsibility or liability, while acting as Client's agent.

4.7 Waste not accurately identified by Client on the Waste Profile Sheet shall be deemed Nonconforming Waste. Client shall defend, indemnify and save harmless EnviroServe, including its respective officers, directors, agents, employees, affiliates, parents and subsidiaries, of and from any and all claims, demands, causes of action, damages, costs, expenses, attorney’s fees, losses or liability, in law or in equity, of every kind in any nature whatsoever related to or caused by Nonconforming Waste, including without limitation, reasonable charges for the handling, transportation, testing, collection, management, storage, and disposal of any Nonconforming Waste, and all time, expense, costs, damages and fines incurred relative to such Nonconforming Waste. Risk of loss and title to Nonconforming Material shall at all times remain with Client (as if not accepted by EnviroServe, as if EnviroServe had not accepted custody or possession). Client agrees to promptly accept the return of any Nonconforming Waste, and of materials which are not accepted by the designated transfer location (or disposal facility). Any obligations imposed on EnviroServe, including those to defend, indemnify and/or hold harmless, shall not apply to the extent the losses were caused by or relate to Nonconforming Waste.

5.2 Client agrees to pay EnviroServe for additional items not detailed in the Service Rate Schedule or items subject to regional variance as a cost plus item. Cost plus is the actual invoice cost for an additional item plus the percentage indicated in the Proposal Rate Schedule. Projects requiring prevailing wages will require a revised rate schedule specific to that project. EnviroServe's compensation does not include sales, use, excise or similar taxes, and such taxes applicable to the services, if any, shall be paid by Client. The Service Rate schedule includes the cost of the EnviroServe basic medical monitoring program. Any special medical monitoring required by Client or by the nature of the work will be added to the project scope for which

Client agrees to reimburse EnviroServe as an additional cost plus item.

5.3 If, subsequent to the date of this Agreement, (a) any new law, regulation or requirement is promulgated or the interpretation or enforcement of any existing law, regulation or requirement is changed, or (b) Client or any third party adopts any new procedure or policy, or amends any existing procedure or policy, which increases EnviroServe’s costs, EnviroServe will compute the cost changes and adjust EnviroServe’s rates to reflect such changes. Client will have the right to review EnviroServe’s calculations for changes hereunder prior to the change going into effect; provided that any such change will be effective from the date on which EnviroServe begins to incur such additional costs.

5.4 Client agrees to pay EnviroServe invoices within thirty (30) days of the invoice date (or if different, within the terms listed in the Proposal Rate

Schedule) and shall not delay payment for any reason, including but not limited to being a party to an insurance claim, lack of insurance, delays in providing documentation, and/or invoice dispute. Client agrees to accept and be responsible for a finance charge of 1-1/2% per month on all past due invoices. In the event that forcible collection action is required, Client shall reimburse EnviroServe for all costs of the collection action, including reasonable collection agency fees, attorney fees and court costs. Client hereby authorizes any insurance company involved to pay EnviroServe directly for services provided.

5.5 EnviroServe may, without liability or obligation, withhold its services under this Agreement if Client fails to timely pay amounts invoiced by

EnviroServe that are not timely disputed in writing and in good faith by Client.

5.6 In the event that EnviroServe provides documentation for the services provided, Client agrees to promptly review and return draft documents to

EnviroServe within five (5) days from receipt. Client agrees that delays in providing documentation shall not delay payment by Client to EnviroServe.

5.7 Client hereby authorizes EnviroServe to conduct credit checks and verification of the financial condition and ability to pay of Client. Upon request, Client agrees that EnviroServe will have the right, at its expense, to examine, audit, copy, or inspect the books, records, and accounts of Client pertinent to the purpose of verifying the accuracy of the performance of Client under this Agreement.

5.8 EnviroServe may, upon thirty (30) days written notice, make changes to the terms and conditions of this Agreement with respect to the scope and performance hereunder. If such change causes an increase in the price, fees, or time period for the performance of the services, this Agreement shall be modified accordingly. Client has the right to object to said changes, and shall do so, if at all, within said thirty (30) day period. If the Parties fail to agree on such modifications, EnviroServe shall have the right to terminate this Agreement with no further liability or obligations hereunder. EnviroServe shall not be bound by any change orders unless signed by a duly authorized representative of EnviroServe.
