Amendment 0002 Solicitation 140R2026Q0074 New Melones Lake Pest and Weed Management

The Solicitation cited in block 9A above, New Melones Lake Pest and Weed Management is hereby amended.

Purpose: The purpose of this amendment is as follows:

1) To provide answers to the questions received, as listed below.

2) To provide an updated Performance Work Statement (PWS). Please see the added text highlighted in the document.

3) To provide an updated Pricing Schedule in the spreadsheet (Pricing Schedule and Service

Locations).

Question 1. What is the required survey or mapping area around each facility for invasive species assessments?

Answer 1. Boundaries for mapping and surveying differ depending on the type of abatement. Pest abatement consists solely of structures highlighted in Section B and abatement should take place in the immediate vicinity of the structures in a controlled manner targeting just the structures exterior themselves.

Weed abatement requires targeted techniques for invasive species listed in the “Targeted Invasive Weed Survey” subsection of the “Survey and Mapping” section of the PWS. The zone of interest for targeting invasive species includes roadways with a minimum of 5 feet from the edge of the roadway, and 1.5 feet on either side of trail corridor. The combined milage of trails between both recreation areas is approximately

Question 2. Please clarify where biological surveys are required. Are surveys limited to the facilities identified in Section B, or do they also include roadsides, trails, and other adjacent areas?

Answer 2. Invasive plant surveys should be conducted in areas defined in the above response’s Weed Abatement section.

Pest abatement is to be conducted in and around all facilities listed in Section B unless otherwise specified exempt by the COR. Reasons for exemption are typically limited to restricted access to facility due to closure.

Question 3. Please provide any permits, environmental documentation, prior studies, or supporting documents associated with this requirement that are driving the scope of work for this

RFQ.

Answer 3. If this is regarding permits or licenses the awarded contractor is responsible for identifying, acquiring and maintaining up-to-date permit and licensing documentation, and providing copies of said documentation, to COR prior to commencing work.

Question 4. Is there any historical information or documentation available regarding previous invasive species monitoring, mapping, or treatment work performed at Lake Melones?

Answer 4. We have had turnover in our resources department within the two years so unfortunately if there was any historical documentation available regarding invasive species monitoring, mapping or treatment work they are most likely lost.

Question 5. Has it been determined whether this requirement qualifies as a sole-source procurement? If so, would the Government consider an extension to the proposal due date?

Answer 5. Based on the results of the sources sought notice, the Government identified several small businesses capable of performing this requirement. Therefore, this procurement does not qualify as a sole-source action and proceeding on a competitive basis is in the Government’s best interest. The quotation due has been extended to June 26, 2026, at 11:00 AM Pacific Daylight Time.

Question 6. Could you please provide the prior annual award amount for this service contract?

Answer 6. $41,495.32 for the Base Year. Previous contract 140R2024P0061 was Base Year plus One Option Year.

Question 7. What specific contractor licenses are required?

Answer 7. All necessary licenses in accordance with Federal, State and Local laws for safely handling/applying herbicides and pesticides. Additionally, contractor must have training on conducting native ground nesting bird surveys. For pesticide and herbicide application California regulation requires licensing and credentials through the Department of Pesticide Regulation.

Question 8. Will there be a pre-bid meeting? If yes, please confirm the correct pre-bid meeting information?

Answer 8. Unfortunately, a pre-bid meeting will not be occurring due to staff being stretched thin. It is welcomed for all perspective bidders to visit the project site during regular hours of operation.

Question 9. Is there an anticipated treatment schedule, estimated treatment acreage, or work plan available for Year 1? Additionally, are there any projected treatment frequencies, locations, or acreage estimates available for the option years?

Answer 9. Weed abatement along both sides of Whittle Road is approximately 50 acres starting from highway 49 to the entrance of Glory Hole Recreation Area. Weed abatement on Reynolds Ferry Road consists of approximately 250 yards on either side of the road managed by Bureau of Reclamation before entering Tuttletown Recreation Area.

Question 10. If treatment activities do not begin until after September 30, 2026, would nesting bird surveys still be required during Year 1, or would those surveys only be required when treatment occurs during the migratory bird nesting season?

Answer 10. If weed abatement work is completed before March 1 and after September 30 then nesting surveying is not necessary. Please keep in mind that all scheduled weed abatement may be conducted before the nesting season but if hazardous tree debris or other work is necessary during the nesting season, which is likely, nesting bird surveys will still be required. Therefore, it is a requirement to have a member of the contract that is qualified for such activity.

Question 11. Is biological monitoring required during active treatment operations, or is the biological scope limited to pre-activity surveys, mapping, and reporting?

Answer 11. Biological monitoring is always recommended during treatment. During the nesting season specified in the Performance Work Statement it is required to have qualified personnel to conduct nesting surveys.

Question 12. Should biological/environmental deliverables and reports be submitted directly to the COR, or routed through the prime contractor?

Answer 12. All reports and deliverables submitted to the COR are appreciated. Especially in advance to submitting invoices.

Question 13. How much advance notice will be provided prior to scheduled treatment activities requiring biological surveys or compliance support?

Tuttle Town Entrance & Access Rd. ( Reynolds Ferry Rd.) Pg. #5

Answer 13. A schedule must be proposed by the contractor and work will be completed by said contractor upon approval by the COR. Areas that are currently open to the public can then be completed at the discretion of the contractor while areas that are closed to the public will require more coordination with the NML staff and/or the COR.

Question 14. Are treatment activities expected to occur within planned seasonal work windows, or should contractors anticipate treatment events being scheduled on an as-needed basis throughout the year?

Answer 14. Herbicide and Pesticide application is seasonal dependent to account for seed and breeding seasons for invasive plants and pests respectively. Trail maintenance is a duty that can occur year around as it is dependent on trail conditions and observations from New Melones staff and Recreators.

Question 15. Is it possible to schedule site visit on Friday?

Answer 15. It is always welcome to visit the project site. Unfortunately, a pre-site meeting can’t be arranged before the bidding deadline closes.

Question 16. Regarding the subject line solicitation, is there an incumbent contract in place or is this a new requirement. If there is an incumbent, can the contract number be provided as well as a brief description of any changes made to the scope of the previous solicitation?

Answer 16. Currently, there is no active contract in place. The most recently expired purchase order is number 140R2024P0061.

Question 17. Can the section B pricing schedule and CLIN structure be provided? We do see Section B which states facility names, types, and locations but frequency of service is not provided.

Answer 17. Section B which states facility names, types, and locations is start on page 6 of the Performance Work Statement (PWS). Please see updated Pricing Schedule.

Question 18. What is the required service frequency for each facility type?

Answer 18. At least once per year for every facility in Section B unless treatment needs to occur more frequently due to pest reoccurrence.

Question 19. Will all 45 facilities be requiring pest control services?

Answer 19. Yes, pest control is required of every facility in Section B.

Question 20. Which facilities, if any, are serviced on an as-needed basis?

Answer 20. Breezeways are the most common “as-needed” services for rodent trap maintenance. Additionally, addressing trail conditions is another ‘as-needed’ service that can occur if trail conditions call for it.

Question 21. Are bait stations currently installed? If so, how many?

Answer 21. There are a few bait traps set throughout the administration building, archaeology and maintenance buildings. Plan for most, if not all, sites listed in Section B to need at least one bait trap.

Question 22. What are the estimated treatment acreages for targeted invasive species?

Answer 22. For roadside weed abatement approximately 50 acres should be estimated.

There is approximately 31.5 miles of trail to be serviced.

Question 23. What are the total roadside miles requiring vegetation control?

Answer 23. Approximately 2.2 miles of roadway tween Whittle Road and very short section of Reynolds Ferry Road.

Question 24. What is the frequency of service for roadsides? Or will it be measured by site conditions being maintained within a determined performance threshold with frequency determined at contractors’ discretion?

Answer 24. Frequency is dependent on variables such as optimal invasive plant treatment periods. And effectiveness of treatment.

Question 25. What are the trail vegetation management quantities? The trail map appears to depict ~30 miles, can this be confirmed?

Answer 25. Correct. Approximately 31.5 miles of trails will need to be serviced.

Question 26. How often are trails expected to be maintained? (annually, monthly during growing season, etc.)

Answer 26. It can vary. That said, it can be assumed that about once per month, at least one trail will need some level of maintenance conducted. Some months will need no work, but others may need multiple days’ worth of cleanup or weed abatement.

Question 27. Are aquatic herbicides anticipated? The PWS references New Melones Lake but does not clearly state whether aquatic vegetation treatment is included.

Answer 27. Aquatic vegetation treatment is not within the scope of this contract.

Question 28. What is the frequency in which bird nesting surveys will be completed annually?

Answer 28. If weed abatement work is completed before March 1 and after September 30.

Please keep in mind that all scheduled weed abatement may be conducted before the nesting season but if hazardous tree debris or other work is necessary during the nesting season, which is likely, nesting bird surveys will still be required. It is difficult to give an accurate number.

Question 29. What is the survey acreage?

Answer 29. For roadside weed abatement approximately 50 acres should be estimated.

There is approximately 31.5 miles of trail to be serviced.

Question 30. What GIS deliverables are required/preferred (ESRI shapefiles, Geodatabases, PDF maps)

Answer 30. Any legible and clearly marked maps, aerial photos, or other similar tools will be acceptable.

Question 31. Licensing Requirements (Factor 2): The Addendum to FAR 52.212-1 requires the submission of a California C27 Landscaping License. Please clarify if the Government will accept a subcontractor’s C27 license to satisfy the "Factor 2 – Certification" evaluation criteria if that subcontractor is performing the relevant landscaping and weed abatement tasks.

Answer 31. Initial research suggests that a C27 Landscaping license would not cover herbicide and pesticide applications. Licensing should be acquired through Department of Pesticide Regulation.

Question 32. Estimated Quantities vs. Pricing Schedule: PWS Part A.2 states that the Contractor must track "actual quantities against the contract’s estimated quantities" and notify the COR when any item reaches 75% of the estimated quantity. However, the Section B Pricing Schedule only contains a single monthly CLIN for "Pest and Weed Management" per year. Can the Government provide a breakdown of the specific estimated quantities (e.g., total acreage for weed abatement or estimated labor hours) that form the basis of these CLINs?

Answer 32. Please see updated Pricing Schedule.

Question 33. CLIN 00000 Pricing: In the Pricing Schedule on page 4, CLIN 00000 describes the global requirement to provide management, labor, and materials. However, there are no pricing fields (Quantity, Unit, or Extended Price) associated with this CLIN. Please confirm that CLIN 00000 is informational only and that all associated costs should be distributed across the performance of CLINs 00010 through 00050.

Answer 33. Yes, that is correct.

Question 34. Trail Maintenance Specifications: PWS Part B.4.d states that approximate trail lengths are specified in Section B. However, the provided Section B table only lists facilities and structural square footage. To ensure accurate pricing for the 1.5-foot cleared corridor requirement, can the Government provide the linear mileage or footage for the trails identified on the project map?

Answer 34. Please see updated PWS which corrected this discrepancy.

Question 35. Structural Pest Control Frequency: Regarding structural pest abatement in Part B.4.a, please clarify the required performance frequency (e.g., monthly, quarterly, or on-call) for the 35+ structures identified in the facility list.

Answer 35. Frequency depends on type of pest abatement. Application of pesticides may only be necessary once per year but could require more applications depending on severity of infestation or effectiveness of pesticide applicants. Rodent control will require more frequent care and may, in certain instances, require an on-call visit to be cleared out and reset.

Question 36. GIS Mapping Standards: For the "detailed GIS map" deliverable required in Part B.4.b.ii, does the Government require a specific file format (e.g., Esri Shapefile, GeoJSON, or KML) or specific metadata standards for the survey areas?

Answer 36. As long as the file is readable without subscriptions or paywall any file format is acceptable.

Question 37. Biologist Credentials: PWS Introduction requires bird surveys to be performed by a "qualified biologist or natural resource specialist". Should the credentials and resumes for these personnel be included in the Technical Approach (Factor 1) submission for evaluation, or are they only required at the pre-work meeting?

Answer 37. Yes, the credentials and resumes for these personnel should be included in the Technical Approach submission for evaluation.

Question 38. Water Availability: For the application of herbicides and chemical treatments, is there a government-furnished water source available for Contractor use at the New Melones Office or recreation areas, or is the Contractor responsible for trucking in all necessary water to the dispersed work locations?

Answer 38. Ideally in most situations water will be supplied by contractor. That said in most cases there are available ¾ inch threaded water spickets in both recreation areas and NML HQ complex. Pre-coordination with COR or NML staff would need to occur to utilize some of these water sources.

Question 39. Incumbent Contractor: Could you please confirm whether there is a current incumbent for this contract? If so, we would appreciate it if you could share the associated Purchase Order number and the total contract value.

Answer 39. This information is available on the expired purchase order number 140R2024P0061.

Please note, the submission deadline for quotes hereby extends to June 26, 2026, at 11:00 AM Pacific Daylight Time.

The contractors must acknowledge this amendment by submitting a signed copy of the Standard Form (SF)-30 along with the quote.
