Conduct soil NTCRA under CERCLA at Caneel Bay Resort Attachment 4a: Clarifications with Amendment 1

Virgin Islands NP

Staging Area

1. Will the Contractor have access to any facilities for restrooms, tool storage, project materials storage, field office during the performance of the Work?

a. No structure is provided to store tools or project materials.

b. No restrooms are available on site (reference Attachment 1, Section 01 50 00, 3.2).

c. No building is available for field offices.

2. Is there an area designated for a job trailer, equipment trailer, etc.?

a. Contractor may use the staging area identified in the pre-proposal site visit PowerPoint (a currently unused overflow parking lot near the Resort entrance) for storage of materials. Anything of value should be secured.

Sampling and Project Engineer Questions

1. Will the Project Engineer or Contractor be responsible for soil sampling for waste profiling purposes?

a. Per Attachment 1 Specification section 02 61 29-2, section 2.2, “Waste profiling shall be conducted by the Contractor in accordance with the requirements of each disposal facility.”

2. Is the Contractor or Project Engineer responsible for surveying final excavated extents and elevations?

a. Contractor is responsible for surveying final excavated extents and elevations.

3. The work plan states that the Project Engineer will collect confirmatory sampling. Will the Project Engineer be responsible for preservation, transportation, and laboratory analytical costs of all confirmatory soil samples?

a. Yes, Project Engineer is responsible for preservation, transportation, and laboratory analytical costs of confirmatory samples.

4. Will any confirmation soil samples or waste profile samples be analyzed for PCBs?

a. No. PCBs are not listed as contaminants of concern (COCs) in the EE/CA or NTCRA Workplan. Similarly, no removal action goals for PCBs were determined.

However, the destination landfill may require PCB analysis, which is beyond NPS control. NPS does not have the authority to waive this requirement if set by the receiving landfill.

5. Is the Contractor responsible for sample collection, analysis, and associated costs, to meet the Clean Fill Protocol?

a. Yes, see Attachment 1, Section 31 23 23-2.1A.

6. Are we correct in assuming that the analytical results in the solicitation package, does not meet any exceedances for any RCRA contaminants?

a. Per Attachment 1 specification section 02 61 29-1.1B, “Based on current Site data, contaminated soils and sediments are not expected to be classified as Resource Conservation and Recovery Act (RCRA) Hazardous Waste.”

7. What is the expected turnaround time for confirmation sample completed by the on-site Project Engineer? Per section 5.6 Project Engineer (PE) will collect confirmation samples and shipped to a commercial laboratory for analysis. What is the turnaround time that NPS wants us to assume for receiving the results which will determine if an excavation area is considered clean and can be backfilled?

a. Previous contract(s) with air monitoring received 24-hour turnaround from when samples were received. FedEx shipments are picked up on Tuesdays and Thursdays in town. The closest certified lab is in Puerto Rico. NPS cannot guarantee or assert lab processing times. The expectation is that confirmation sampling results will be provided to the PE within three days after receipt by the lab, based on the assumption that we will ask for 48-hour turn-around time and one day for shipping. The realized number of days will be affected by FedEx’s limited pick-up schedule and other factors beyond the control of NPS or the PE;

therefore, a specific turnaround time is not guaranteed.

8. Will there be any air monitoring being conducted by the on-site engineer?

a. Yes, see Attachment 1 section 5.5.1 Air Monitoring for air monitoring activities at the landfill for potential landfill gas, and dust monitoring in the worker breathing zone. Specification section 01 57 19-2.3 Control of Dust states that "The Project Engineer will conduct monitoring for respirable dust using a Portable Dust Monitor within and along the perimeters of the Work Areas. The Contractor shall implement dust control measures at the direction of the Project Engineer, based on their monitoring activities." See also Attachment 2a, Revised Addendum.

Note: All responsibilities/tasks not specifically stated for the Project Engineer to complete are the responsibility of the Contractor.

Excavation, Handling and Disposal of Waste

1. Can non-hazardous or non-contaminated soil/material be disposed of at Bovoni Landfill on St. Thomas pending landfill approval?

a. Non-hazardous, non-contaminated soil/material may be disposed of at the Bovoni Landfill on St. Thomas, or the landfill on St. Croix, if they accept the material.

Space is limited at the U.S.V.I. landfills, so advance coordination by Contractor with the landfill operator(s) is paramount.

2. Waste movement/disposal

a. Will all of the contaminated soils and landfill refuse from designated Areas 2 and 3 need to go the US mainland? Where does the government want waste to go for disposal? Can all soils/debris be managed at a Subtitle D landfill?

i. All excavated material shall be legally disposed of off-Site. The landfills in the U.S.V.I (located on St. Thomas and St. Croix) have limited capacity. Landfills in the U.S.V.I. are not permitted to receive hazardous material. Non-hazardous material may be disposed of at the Bovoni landfill on St. Thomas or landfill on St. Croix if they agree to accept it.

Excavated landfill contents identified to contain hazardous material cannot be legally disposed of at local landfills. In the event excavated material from Area 3 cannot be disposed of at the Bovoni Landfill on St. Thomas, or the landfill on St. Croix, it is Contractor’s responsibility to ensure it is legally disposed of on the US mainland.

3. Decontamination water/leachate:

a. Can decontamination water be disposed of locally or does it need to be sent to the continental US?

i. See Attachment 1 Specification section 02 51 00-3-D, “The Contractor shall capture, collect, and store all water used during decontamination activities. Decontamination water shall be stored in DOT-approved containers. Stored decontamination water shall be sampled for waste characterization and disposed of in accordance with applicable State, Territory, and Federal regulations.” Additional information is provided in preceding and proceeding sections.

b. If disposal of leachate from dewatering is a realized contingency, would that be handled as a contract modification? (NTCRA Spec 02 61 13-3.9A-5)

i. Yes, if a dewatering plan and corresponding dewatering action is required by the CO, the contractor will be entitled to an equitable adjustment to the contract price, which will be codified in a contract modification.

4. Shipping:

a. Does the NPS require shipping documents from the site to the terminal on St.

John’s in addition to shipping manifests for the ocean travel and landside shipments at CONUS?

i. Shipping manifests shall reflect origination from the U.S.V.I.

ii. Per Specification section 02 61 29-1.2-C, waste manifests, weight tickets, bills of lading, and other waste disposal documentation for all materials removed from the Site for disposal are required.

iii. Separate manifests may be necessary to reflect ‘overland’ shipment from Caneel Bay Resort on St. John to the port on St. Thomas and oversea shipping to document the full path of transport.

b. Due to new regulations at St. Thomas’ port, will shipments be delayed?

i. The shipping yard on St. Thomas can only hold hazardous materials for up to 72 hours. Contractor will need to plan accordingly to move materials categorized as hazardous to the shipyard in preparation for barge departure in coordination with the port.

c. Can Contractor move materials off-site through a barge directly from Caneel Bay Resort?

i. No. There is insufficient infrastructure for this action and the bay is shallow.

5. It appears that asphalt removal may be required for Excavation in Area 2. Is repaving of these surfaces required under this contract?

a. No asphalt excavation is required. No repaving is required.

6. Can all grubbed, chipped and cleared vegetation remain in the designated Caneel Bay Resort area, or does it need to be hauled away? Would mulching be of interest for beneficial reuse? Can chip cut vegetation that is stockpiled as directed by NPS remain in stockpiles if re-use is not elected (NTCRA Spec 31 11 00-2)?

a. Per Attachment 1 Specification section 31 11 00-3.4-A, “chip cut vegetation and stockpile as directed by NPS. Chipped vegetation may be spread as mulch, as required in accordance with Section 32 90 00.” Section 3.4-B provides that “stumps, roots, and buried vegetative debris removed during excavation of contaminated soil shall be disposed of off-Site with the excavated soil unless soil is able to be segregated from the woody debris and such debris is determined to be considered substantially free of soil following a visual inspection by the Project Engineer.”

b. Mulched on-Site vegetation may be applied on-Site as an erosion control material, to protect seeded areas, or to repair areas of unsatisfactory vegetation, per specification section 32 90 00.

c. Per specification section 01 57 19 mulch may be generated on-Site and/or used as a dust control method.

d. Unused mulch or other chipped and grubbed vegetation shall be hauled away unless otherwise directed by Contracting Officer.

7. Is the term Landfilled Material referenced in Area 3 a catch all for soil used to cover solid waste as well as the solid waste itself? Contract Price Schedule line 9 solely notes soil loading, transport and disposal. (RFP, Section B: Price Schedule)

a. Yes, Landfill material covers all items that comprise the landfill. The word “soil” in CLIN 9 in the price schedule and Attachment 1 Specification section 01 27 00, Definition of Line Items, should be interpreted as “Landfill Material.”

8. Is an electric/explosion proof excavator required considering the Haz 1 Div 1 classification of the area (no hot work allowed). (Attachment 1 NTCRA Work Plan, Spec 01 57 19, page 4)

a. An electric or explosion-proof excavator is not required.

9. On page 12 of the Caneel Bay Non-Time-Critical Action Work Plan, Table 2 Summary of NTCRA Areas carries a superscript note #3 in the column for “anticipated volume”.

This note references “Development” in Section 4.2 Coastal Zone Management Act pg 10.

How does superscript note #3 tie to the “anticipated volume”? (Attachment 1, NTCRA workplan, section 5, table 2, page 12)

a. Superscript at Anticipated Volume should refer to footnote #4.

10. The Contract Price Schedule denotes quantities by tons/weight and Option A and Option B are represented by cubic yards/volume. Please indicate how the soils and solid waste will be measured by NPS. If tonnage is the chosen method, will the contractor need to provide the scale system?

a. Items 3, 6, 8, and 9 in the price schedule are by tons while Options A and B are by cubic yards due to commercial practices. Tons will be measured by weight tickets from the disposal facilities and soil quantities will be measured and calculated by adding up purchase tickets from source(s); see Section 01 27 00 of Attachment 1, Appendix 1. We anticipate that the contractor will rely on the disposal facilities’ scales.

11. In WP Table 2, under the first line item Area 2 Surface Soil, the removal units are listed as A2-Soil1, A2-Soil2, A2-Soil3 and A2-soil3. It looks like A2-soil3 was inadvertently duplicated in the table. Please confirm this was an accidental duplication of A2-soil3, and that another soil unit was not accidentally left off the list.

a. There is an error in Text Table 2. The removal units include A2-Soil1, A2-Soil2, A2-Soil3, A2-Soil4. Please refer to the embedded table in Figure 2 which indicates the locations and estimated volumes of each unit.

12. Attachment 1 Specifications 02 61 13-3 under Section 3.3 doesn’t list A2-Soil 4 for surface soil removal. Is area A2-Soil4 included in the scope for surface soil removal?

a. A2-Soil4 was accidentally omitted here as well. Refer to Figure 2 for areas and estimated volumes.

13. The WP Figure 2 indicates the A2-SU 1, A2-SU2, A2-SU3 and A2-SU4. However, it appears these areas are not listed in the Table 2 and not stated anywhere that they needed to be excavated. We assume these is no action required for these areas, please confirm.

a. These are confirmation sampling units – the intent is for the Project Engineer to collect these samples prior to excavation in Area 2. Proposals should not include excavation of these areas in Contract Line Item Number 3.

14. Under WP section 2.2 it states that Waste Profiles will be signed by authorized agent for NPS. However, it is not clear who will sign the waste manifests for the project? Also clarify if the authorized agent will be onsite on daily basis during the Transportation of wastes.

a. NPS will coordinate with Contractor to ensure an authorized agent is available to sign waste manifests for the project in a timely manner. Contractor should identify in their proposal if the authorized agent is required on a daily, weekly, biweekly, or other interval to sign manifests.

15. Under WP section 1.4, it states that before site work begins, contractor shall meet with contracting officer and Archeological monitor to discuss Daily work schedule, equipment, and special methods used in archeologically sensitive areas. Are there any archeologically sensitive areas within or near the excavation areas? If so, please provide an updated figure showing these areas?

a. No known undisturbed archaeologically sensitive areas are known within the identified excavation areas. The Park’s cultural resource specialist will join the initial kick-off call and first day on site to brief Contractor’s crew of potential nearby resources and items to look out for during excavation.

16. The mainland landfill lab technicians are requesting a full analytical report for the contaminants of concern. Can you please provide the complete report?

a. See files EECA Tables 1-5 and Tables attached to the 2021 Risk Report for a Summary of Soil Analytical Results on the Park Planning EE/CA webpage for Caneel Bay Resort.

Fill and Backfill

1. In Section 31 23 23, it’s stated that the compaction standard must meet “compaction density as approved by the Project Engineer.” Are there any specifications for backfilling requirements of the landfill (Area 3), including engineered compaction or density requirements.

a. The landfill will not be backfilled, see Workplan section 4.2, 4.3, 5.3; Figures 4a, 4b, 4c. Landfill contents will be removed, confirmation sampling completed, then area will undergo minor grading to return to pre-landfill, natural conditions.

2. The specifications seem to indicate that import of topsoil is not included under the base scope and that all topsoil will be generated onsite unless excavation goes beyond the limits shown on the drawings. Is that correct?

a. No - see specification section 01 27 00, paragraphs 3D and 3J: some topsoil importation and placement is included in CLINs 4 and 10.

b. Refer to specification sections 01 11 00-1.2-D-2(h), and 4(j), 01 27 00, 31 23 23.

References include “backfill excavations with topsoil from an approved clean fill source.”

3. For the topsoil and common fill, does the NPS want these sourced locally to possibly prevent any foreign invasive plants, seeds or root cuttings from coming into the Virgin Islands?

a. See Attachment 1 specification section 31 23 23-2.1A and B. Section B-2 notes “Topsoil shall be fertile, natural soil, typical of the locality....and obtained from an area confirmed to be free of invasive plants.”

Security and Access and Traffic Control

1. Will the contractor need to provide 24hr. security for the site?

a. No.

2. Is there security fencing that needs to be installed?

a. 01 50 00-3.4 site fencing, “sufficiency of fencing types and locations to be determined by the Project Engineer based on work area conditions.”

b. The contractor shall install safety fencing around excavations left open overnight.

c. 01 26 01-1.2C Temporary fencing is included in general requirements.

d. Contractor’s mobilization and safety plan should address where safety fencing and/or other fencing is needed.

3. Will the contractor be responsible for the onsite construction trailers for the NPS, besides their own?

a. Contractor is responsible for their own on-site construction trailers. The contractor is not required to provide a trailer for NPS’ or Project Engineer’s use.

4. Will dust control measures for haul roads need to be implemented, and street cleaning of the North Shore Road service entrance need to be cleaned daily?

a. Dust control is required on access/haul road, see section 01 57 19-2.3A-F. Street cleaning where the dirt/gravel access road transitions to asphalt shall occur at a minimum weekly, or more often if conditions deteriorate.

5. Does traffic control for trucking on the service entrance to North Shore Road need to be implemented? USVI Police detail?

a. No.

6. What traffic control measures must be implemented on the site and Area 3 for the shared haul road? Hand Direct Radio?

a. The following requirements are added to Attachment 2, Addendum, Appendix 1, 026129, Section 1.2, Submittals:

i. The transport and disposal plan shall comply with the “Manual on Uniform Traffic Control Devices (MUTCD) for Streets and Highways” (Federal Highway Administration (FHWA), 2012). The plan shall ensure that adequate consideration will be given for the safety and convenience of motorists, pedestrians, and workers during the removal action both within the Site and between the Site and off-Site delivery areas.

ii. General Approach. The general traffic controls discussed below are most applicable to work at the Site.

• All traffic at the Site will be routed with traffic control devices and road layouts comparable to those for normal highway situations.

• Traffic movement will be maintained as normal as practical. Preparations for safe traffic control for work and construction vehicles will be made.

• All traffic control devices will be removed immediately when no longer needed.

• Traffic will be channeled by the use of signage, flexible posts, and other lightweight devices that will yield if hit by vehicles.

• Traffic controls or working conditions may be modified to promote worker safety. Worksites will be carefully monitored under varying conditions of traffic volumes, light, and weather to ensure that traffic control measures are operating effectively, and that all devices used are clearly visible, clean, and in good repair. Work zone accident records will be analyzed periodically.

Other

1. Does this project include any lead or asbestos abatement/remediation?

a. No.

2. Where was Area 1 excavated material disposed?

a. Area 1 has not been excavated because it was determined through the EE/CA process that it did not require excavation.

3. Are there any blueprint drawings or as-built drawings identifying underground utilities that may be present in the designated remediation sites?

a. There are four drawings available that show the location of various utilities buried within and around the Maintenance Area that are uploaded to the solicitation at SAM.gov as Attachment 5. There may be additional underground utilities that are not shown on the available drawings. NPS does not guarantee the accuracy of these utility drawings.

b. Note, the identified removal depth for soil around the Maintenance Area is 6 inches. Utilities are expected to be buried deeper than 6 inches.

4. The solicitation documents identify a monitoring well to be abandoned. Do you know the depth of the well and are there any soil boring logs associated with this well?

a. Well depth is 14 feet. Refer to Attachment 5 for MW-3-01 construction details and accompanying soil boring log SC-3-09.

5. Specification Section 01 27 00.3.H.3 states that “Payment will be made on a unit price basis for the actual quantity per ton, using the quantity determined in CLIN 7.” Clin 7 is a lump sum CLIN. Is this referring to CLIN 9?

a. This is an error. The quantity for CLIN 8 will be based on the quantity of CLIN 9.

6. Is offsite water service available from the resort operator or from a local utility company?

a. Potable water is available from local companies.

7. When were the photographs taken? Is this representative of the amount of vegetation to date, or should contractors assume that additional growth has occurred?

a. Photographs were taken between January 2021 and January 2022. Contractors should assume additional growth has occurred since.

8. Performance period:

a. Please clarify the start period of the expected performance window (award date vs notice to proceed date) between Block 11 on page 1, 52.211-10 on page 5 and Attachment 2 Appendix 1, 013100, Section 1.2(D).

i. All work must be completed within 390 days after issuance of the Notice to Proceed (NTP). The NTP will be issued after acceptance of the bonds per FAR clause 52.211-10 addendum.
