ADDENDUM ITEMS:

I. Prebid Meeting Attendance Record DTMB-0441 dated 7/30/26 II. Questions (Q – Question, A – Answer)

1. Q: Is the Tetra Tech document titled “Health and Safety Requirements for Various

Services in Support of High-Hazard Site Projects” applicable to this contract?

A: No, please disregard this document. The project posting inadvertently included the document.

2. Q: Task 3, Gas Collection System Monitoring, in the Statement of Work (SOW) identified liquid levels as a required monthly sampling event at each extraction well and at the gas-header sampling port?

A: EGLE would like to decrease the proposed frequency for sampling liquid levels at wells from monthly to semiannual. There will be no liquid level monitoring at the gas-header sampling port.

3. Q: The Statement of Work (SOW) specifies a Flame Ionization Detector (FID) to identify gas leaks. Would EGLE accept an infrared methane detector in place of an FID for leak detection?

A: Yes, an infrared methane detector or other approved equivalent instrument would be an acceptable alternative.

4. Q: Are UTVs/ATVs permitted on site for routine monitoring?

A: Yes, UTVs and ATVs are permitted on site and on the landfill cap for routine monitoring. However, any damage to the landfill cover, pipes or landfill systems due to using UTVs/ATVs must be repaired to the original conditions at the expense of the contractor.

5. Q: Does the site have any restricted access areas or seasonal limitations?

A: There are no restricted access areas at the landfill. The only seasonal limitation I can imagine would be snow on the site roads and cap during the winter. Typically, the main road to the landfill’s leachate storage tanks is kept plowed.

6. Q: During the required monthly flare inspections (Task 2) is the backup flare expected to be started and operated each month, or is the inspection limited to verifying the ignitor, http://www.michigan.gov/SIGMAVSS pilot, and associated components?

A: If the ignitor, pilot, and associated components can be inspected each month without having to start the backup flare that would be acceptable.

7. Q: Does the monthly flare inspection require removal and cleaning of the flame arrestors each month, or is verify differential pressure and cleaning only when needed acceptable?

A: Verifying differential pressure and cleaning only when necessary, would be acceptable.

8. Q: Are all 59 installed wells active?

A: It was revealed in the pre-bid meeting on 7/30 by Blue Skies Energy that currently there are 47 active wells. For pricing bidders should assume 47 wells will need to be sampled monthly. Blue Skies Energy has not revealed what 12 wells are inactive. The only wells confirmed to be inactive are GW-14, GW-17, GW-35. The initial assessment (task 1) should reveal which wells are inactive. There will be no monthly monitoring responsibilities associated with these 12 inactive wells.

9. Q: The introduction in the SOW references surface emission monitoring but the task breakdown does not define a frequency?

A: There will be no surface emission monitoring (SEM) associated with this contract at this time. The inclusion of SEM in the introduction was inadvertently included.

10. Q: Task 6 in the SOW identified emergency repairs. Is emergency response expected to be 24/7?

A: No, emergency response is not expected to be 24/7.

11. Q: Is a SCADA or remote monitoring system currently operational?

A: For the purpose of pricing, assume that a SCADA or a remote monitoring system is NOT available.

12. Q: Besides lubrication, are there any manufacturer-required quarterly or annual maintenance activities expected under this contract?

A: Chapter 8, Maintenance, in the KerrPump manual provided identified general inspection requirements (8.1) and lubrication requirements (8.2). General inspection requirements should be performed on a quarterly basis. The lubrication requirements should be performed monthly.

13. Q: What calibration gases are required to use?

A: We have no preference for calibration gases for the work associated with this project as long as it’s acceptable under the industry standards.

14. Q: Will EGLE provide report templates and well tuning sheets, or is the Contractor expected to develop them?

A: No templates are available. This would be the responsibility of the Contractor.

15. Q: Will the selected Contractor receive historical well tuning data, flare maintenance records, SCADA data (or eTools), and previous monitoring reports?

A: No. The bidder should assume they will not receive these records.

16. Q: Will EGLE provide available well construction records, drill logs, as-built drawings, historical gas and liquid-level data, blower and flare operating data, maintenance and repair records, and prior SEM data? Please identify when these records will be available to the selected contractor.

A: No. The bidder should assume they will not receive these records.

17. Q: Is the backup flare expected to remain in standby service only, or is periodic operational testing required?

A: The backup flare would be expected to remain in standby service only.

18. Q: Will EGLE provide site-specific health and safety requirements and required training before mobilization?

A: No.

19. Q: Are there any building monitors or perimeter gas probes that need to be monitored? If so, what is the frequency?

A: No.

20. Q: Could EGLE provide a sample contract agreement?

A: The posted documents for this project including DCSpec document and all addenda will be the contract agreement.

21. Q: Can EGLE provide a clear explanation as to the purpose of the Schedule of Alternates and Schedule of Unit Prices Or Contingent Change Order Prices on Page 4 of 75 in the DCSpec, and why would a contractor need to complete these sections?

A: These sections of the DCSpec are not applicable to this project/contract.

22. Q: In the DCSpec on page 66 of 75, the top of the page states, Federal Provisions Addendum, and there is NA in red. Does this mean that this Federal Provisions Addendum does not apply to this contract?

A: Yes, Federal Provisions Addendum does not apply to this contract.

23. Q: What criteria does a company have to satisfy to be considered a Michigan Based Business?

A: Filing a Michigan Single Business Tax (SBT) or Michigan Business Tax (MBT) return or filing a Michigan income tax return or withheld and remitted Michigan income tax. Meeting one of the primary tax criteria, along with demonstrating substantial Michigan presence and granting authorization for verification, is sufficient for a business to be officially recognized as Michigan-based under state procurement rules. No separate state department issues a physical "Michigan-Based Business Certificate." The vendor self-certifies as part of the bid/contract process. The Michigan Department of Treasury then verifies the business meets the state-based criteria. So, the Treasury Department serves as the official verifier of a Michigan-based business’s status.

24. Q: Does this contract require payment of Michigan Prevailing Wage (2023 PA 10) for all routine O&M, monitoring, and emergency repair activities, or only for construction/mechanic work performed under the Annual & Emergency Repairs Allowance? If so, what classification is used for a Wellfield Operations and Maintenance Technician? Can EGLE provide the applicable wage determination for this project??

A: The contract requires payment of Michigan Prevailing Wage for all wages paid by the Contractor to their employees for work performed under this contract. Determining the prevailing wage rate classification that is appropriate for the work performed under this contract is the responsibility of the Contractor. DTMB or EGLE do not enforce the laws for prevailing wage rates. Any questions regarding the appropriate prevailing wage rate should be directed to the Michigan Department of Labor and Economic Opportunity

(LEO).

25. Q: The prevailing wage schedule does not establish rates for equipment used to perform the work. For reimbursable work, should the contractor use it’s standard equipment rates?

A: Yes, for reimbursable work the Contractor should use it’s standard equipment rates.

26. Q: Please confirm whether the Performance Bond and Payment Bond must each equal 100% of the total contract award, including the $50,000 provisionary allowance.

A: Confirmed.

27. Q: The SOW states that subcontractor invoices are reimbursed without markup. Please confirm whether the contractor may separately bill for procurement, estimating, project management, coordination, supervision, and field labor associated with managing and supporting subcontracted work.

A: No invoices are needed from subcontractors. The contractor’s invoice must follow the established schedule of values for the bid.

28. Q: Will the contractor be responsible for paying subcontractors and then seeking reimbursement through the provisionary allowance, or will EGLE contract with and pay subcontractors directly with project coordination from the contractor? Please also identify the required invoices and support documentation.

A: It depends on the agreement signed between the contractor and subcontractors. The State will not pay for items under the provisionary allowance without prior approval and by issuing a contract change order by the State.

29. Q: Which consumables and routine replacement items are expected to be included in the contractor's monthly O&M price, and which items are reimbursable under the $50,000 provisionary allowance? Examples include lubricants, filters, igniters, thermocouples or flame sensors, hose, Fernco couplings, valves, sample ports and associated parts, wellheads, clamps, calibration gas, and similar routine maintenance items.

A: See the Answer to Q #28 above. The bid price quoted for Each Bid Item listed in the Bid Schedule must cover completing the item and include the cost incurred by a needed auxiliary materials/equipment.

30. Q: What approval and documentation process is required before using the $50,000 provisionary allowance? Is written authorization from EGLE required before performing repairs, purchasing materials, or procuring subcontracted work, except when EGLE has designated the condition as an emergency?

A: The process is similar to the PROCEDURE FOR PROPOSED CHANGE ORDERS, except in an emergency endangering life or property no deviation from the contract documents will be allowed without the issuance and approval of the following documents:

EGLE will fill out a bulletin request (DTMB-0485). This bulletin request form shall be addressed to EGLE. After EGLE approval a Contract Bulletin will be issued to the Contractor.

Upon receipt of the bulletin, the Contractor shall promptly (per specifications) prepare and submit a quotation to EGLE. The Contractor shall reference the Bulletin number on their quotation. The quotation must be itemized and follow instructions for allowable costs and markups. Subcontractors to follow the same itemization requirements.

The Contractor’s signature is required on quotation.

After review and evaluation, EGLE will submit a recommendation letter (accompanied by signed copy of the quotation, bulletin, and bulletin request) to the DTMB Project Director.

Upon completing a review, the Project Director will draft a contract change order that will be processed by DTMB to transfer the money needed from the provisional allowance.

DTMB would then issue a Contract Change Order to the Contractor.

31. Q: If a monitored parameter exceeds an applicable limit or action level, what timeline, notification, corrective action, and documentation are required? Please clarify whether rechecks are included in the routine monthly price or reimbursed through Task 6 or other non-routine funds.

A: Regarding wellhead monitoring there are no applicable limits or action levels. The results of monitoring will be provided in the monthly report identified under Task 5.

Rechecks are not included in the routine monthly price for monitoring identified under Task 3.

32. Q: Please confirm that the contract does not require condensate monitoring, measurement, sampling, or reporting and does not include operation or oversight of the site's leachate extraction system. If any condensate-tank inspections or operating checks are required, please define them.

A: There are no condensate monitoring, measurement, sampling, or reporting tasks associated with this contract.

33. Q: Does EGLE anticipate installing air and force main infrastructure, pumps, or other liquid-management equipment during the contract term, including equipment that may be needed to comply with Part 115 requirements? If so, would this work be performed and reimbursed under the provisionary allowance?

A: No, EGLE does not anticipate installing these features during the period of the contract.

34. Q: Please identify the regulatory requirements applicable to this landfill and clarify which compliance responsibilities are assigned to the O&M contractor versus EGLE. This includes, as applicable, Michigan’s Amendments to Part 115, NSPS, NESHAP, greenhouse-gas reporting, air-permit requirements, and any other site-specific regulatory obligations.

A: Any future compliance responsibilities applicable to the landfill are not the responsibility of the Contractor.

35. Q: What routine observations and reporting are expected regarding landfill-cover integrity, erosion, settlement, vandalism, wellfield conditions, leachate outbreaks, flare operation, and blower operation? Please distinguish items the contractor must only observe and report from items the contractor is expected to correct.

A:

• In regard to this contract there are no inspection and reporting requirements for landfill-cover integrity, erosion, settlement, vandalism, or leachate outbreaks.

• In regard to well-field conditions:

o The Contractor is responsible for observing and reporting damage/leaks.

The monthly report should recommend appropriate repairs that would then be paid from the Task 6 Provisionary Allowance following the Bulletin approval process.

• In regard to flare operation and blower operation:

o The Contractor is responsible for observing and reporting the operational status of these components. If the blower or flare was observed to not be operating, it would be the Contractor’s responsibility to attempt to restart these systems. If repairs are needed in order to return these systems to operation that would be paid from the Task 6 Provisionary Allowance following the Bulletin approval process.

36. Q: Site Access and Vegetation Management: What site-access procedures and allowable working hours will apply to the contractor? Please confirm who is responsible for mowing and vegetation management needed to maintain safe access to the gas wells and other LFG infrastructure.

A: The site is accessed via two separate gates along East Mt. Morris. Each gate is secured with a 4-digit padlock. The Contractor would be given the combination for these locks and would be expected to close and lock the gate upon departure. There are no limitations on allowable work hours applicable to the Contractor. Mowing and vegetation management is not a task currently associated with this contract.

37. Q: Site personnel indicated that there is no enclosed flare and that the site has two candlestick flares, with the 6-inch flare serving as the primary destruction device. Will the bid documents be amended to reflect the existing configuration? Please also provide the design capacity and operating range of each flare and confirm whether the 6-inch flare and associated blower outlet pipe sizing into the flare can accommodate the anticipated full wellfield flow after the plant shuts down.

A: The configuration of the gas control system identified in the Statement of Work does not accurately reflect the existing configuration. The gas control system does not include an enclosed flare. Instead, there are two candlestick flares. The 4-inch flare currently serves as the site’s primary flare. All available information regarding the 4-inch flare is provided in Attachment 2 of SOW. There is no available information regarding the facility’s second flare. EGLE can make no definitive statements regarding the primary flare’s ability to accommodate the full wellfield flow. For the purposes of this contract the bidder must assume the flare can handle the full wellfield flow.

38. Q: Please identify the thermocouples or other flame-detection devices, control panels, alarms, automatic shutdown valves, and flow meters that will remain available to the contractor. What type of flow meter will be used, will remote access be available, and how will the contractor obtain current and historical flow and operating data?

A: For purposes of this contract the bidder may assume the equipment observed on-site at the facility will remain available to the Contractor.

39. Q: Please describe the final operating configuration after the plant shuts down. Who will own, operate, and maintain the compressor used to actuate the block valve; the plant owned electrical lines and poles serving the flare yard; and any telephone, cellular, SCADA, or remote-alarm systems? Please also clarify whether the contractor will be responsible for manually routing gas between the two flares and provide the applicable operating procedure

A: The bidder should assume that the equipment observed onsite during the pre-bid meeting and the existing configuration of the plant will remain in place for the term of the contract. No existing operating procedure is available. If routing of gas is needed to perform a task specified in the scope of work, the contractor will be responsible for the cost and performing the task.

40. Q: Site observations and discussions identified aging wellheads, reported vacuum loss in portions of the wellfield, and a history of cracking or leakage at the condensate tank. Will EGLE provide a current deficiency list or baseline condition assessment before contract commencement? Please confirm whether repairs needed to place the system into normal operating condition at turnover will be paid from the provisionary allowance rather than included in the contractor's routine price.

A: No list of current deficiencies will be provided to the Contractor. Repairs necessary to place the gas collection system under normal operating conditions will be paid from the provisionary allowance following the Bulletin approval process.

41. Q: Site observations and discussions identified aging wellheads, reported vacuum loss in portions of the wellfield, and a history of cracking or leakage at the condensate tank. Will EGLE provide a current deficiency list or baseline condition assessment before contract commencement? Please confirm whether repairs needed to place the system into normal operating condition at turnover will be paid from the provisionary allowance rather than included in the contractor's routine price.

A: No list of current deficiencies will be provided to the Contractor. Repairs necessary to place the gas collection system under normal operating conditions will be paid from the Task 6 Provisionary Allowance following the Bulletin approval process.

42. Q: It was discussed during the on-site meeting that the blower and flare configuration has never operated to maintain vacuum control for the gas system for any extended period.

Given the initial site assessment is a required task of the awarded contractor, if those systems are found to be initially non-operational to maintain vacuum control, what is the contractor’s responsibility for routine monitoring during the interim period where repair or upgrades may be necessary?

A: Any monitoring actives not identified in the Statement of Work are outside the scope of this contract.
