1.2 DESCRIPTION OF WORK

The extent of soil excavation including contaminated soil will be limited to the designated depth and width to construct a new structure and utilities unless directed by the Contracting Officer. A soil screening survey was conducted in 2020 to support this project. The report is available upon request. The following paragraphs provide a summary of f the 2020 soil screening survey.

Building 21003 is located adjacent to the west of the project site. At the time of the survey, Building 21003 was partially demolished.

Pesticides Impacted Soil (PIS) was found from the demolished building footprint. The intent of the project is reusing PIS within the project boundary by capping the soil with a minimum one foot of clean soil or a hard surface such as below the new building slab, asphalt, concrete, or other acceptable barriers if the PIS meets geotechnical requirements specified in Section 31 23 00.00 20 EXCAVATION AND FILL. A permeable but protective barrier (i.e. orange warning barrier geotextile) must be placed between PIS and the clean soil or hardscape materials. For site and maintenance workers, the protective barrier acts as an engineering control to provide a simple early warning signal prior to encountering pesticide-impacted materials so that appropriate measures can be taken to prevent exposed materials at the surface when work is completed. Reuse or relocation of PIS in utility trenches are not recommended to prevent unmitigated exposures to the utility workers or the facility users.

SECTION 02 61 13 Page 1 Amendment 0006

Provide a closure report with drawings showing the PIS relocation areas.

If reusing of impacted soil is not feasible, the soil must be disposed of at a disposal facility in the mainland U.S. If disposal of PIS is required, the Government may issue a change order.

1.2.1 Summary of Findings

A soil screening survey was conducted in 2020 at the project areas to be disturbed. The Chemicals of Potential Concern (COPCs) were identified as Total Petroleum Hydrocarbons as Diesel/Residual Range Organics (TPH-DRO/RRO), Polycyclic Aromatic Hydrocarbons (PAH), RCRA 8 Metals, Polychlorinated Biphenyls (PCB), chlorinated pesticides, and asbestos. The analytical results for contaminants were compared to the Tropical Pacific Soil Environmental Screening Levels (ESLs) (State of Hawaii, Department of Health, Fall 2017).

TPH, PAH, PCB, and Heavy Metals: Reportable levels of these contaminants were found within the project boundary, but the results were below the ESLs for unrestricted land use.

Asbestos: Asbestos was not detected in the areas of partially demolished Building 21003 footprint.

Pesticides: Dieldrin was measured at 11 mg/kg {0-0.5 ft below ground surface (bgs)}, exceeding the ESLs for both unrestricted (2.5 mg/kg) and restricted land use (7.9 mg/kg) at the demolished Building 21003 footprint. Reportable levels of aldrin, DDE, DDT, endrin, and chlordane were found in the soil at 0-0.5 ft bgs; however, all results were below the ESL for unrestricted land use.

1.2.2 PIS Boundary and Vertical Delineation

PIS exceeding the ESL was found from the surface soil, 0-0.5 ft, bgs from the demolished building footprint of Building 21003. For the bidding purpose, presume the boundary of PIS exceeding the ESL as follows:

Lat er al Boundar y : Area Building 21003 footprint plus 3 ft lateral distance from the former building footprint

Ver t i cal Boundar y : 0-2 ft bgs

If the soil below 0.5 ft below ground surface is disturbed or excavated, conduct vertical delineation for pesticide contamination. Prior to site disturbance, Contractor may consider two soil samples at two sampling depths, 0.5-2 ft bgs and 2-3 ft bgs, from five independent locations using a composite sampling method in the former building footprint. Analyze the samples by EPA method 8081 for Pesticides. Submit the Soil Testing Report including the detailed sampling method, sample location drawing, results, recommendations, and laboratory analytical report.

1.2.3 Excess Soil Characterization and Disposal

Remove surplus soil generated from the construction in accordance with applicable federal, Guam or local regulations. Surplus soil and stockpile that will be transported offsite for reuse or disposal must be characterized to ensure compliance with the recipient guidelines and requirements. Comply with the requirements for the sampling method and analytes as specified in Section 31 23 00.00 20 EXCAVATION AND FILL.

SECTION 02 61 13 Page 2

1.2.3.1 PIS Disposal

There is no local disposal option for PIS exceeding the ESL for unrestricted land use. If reusing within the project boundary is not feasible, the PIS must be disposed of at a disposal facility in the mainland U.S. The soil contaminated with pesticides leaving the installation must be managed as an EPA regulated hazardous waste (D020), and all RCRA requirements including 40 CFR 263 and 49 CFR 171-179 must be strictly followed.

1.2.4 Engineering controls

Engineering controls must be designed and implemented during site construction to prevent the release of impacted soil during excavation, staging, and hauling activities. Airborne particulates, i.e. dust, silica, can cause unintended exposure through inhalation when a receptor, such as a construction worker or base personnel, is in the area. During earthwork, dust and erosion control must be implemented including, but are not limited to, dust barriers, water misting, stockpile management, silt fences, and site stabilization.

1.2.5 Work Plan

Prepare a Work Plan including a Health and Safety Plan and a Sampling and Analysis Plan. The Plan must be reviewed and approved by the Government prior to site disturbance.

1.2.6 Excavation Monitoring

Conduct excavation monitoring for signs of contamination, such as discolored/stained soil, odors, or free product. Provide hazard communication for the workers prior to any soil disturbance. The Contractor may retain an environmental manager or a competent person for soil monitoring, management, and guidance for personal protection and previously unforeseen site conditions.

1.2.7 Worker Safety

Hazardous Waste Operations and Emergency Response (HAZWOPER) or HAZWOPER training is not required for this project. However, all work must be conducted in accordance with applicable federal (i.e. OSHA and EPA) and Guam regulations and installation requirements (i.e. EM 385-1-1 ). Prepare a Site-Specific Health & Safety Plan, including but are not limited to, engineering controls, personal protective equipment (PPE), worker exposure assessment and monitoring, air monitoring, equipment decontamination, site control measures, and emergency plan. Air monitoring will be required for dust and silica (may use dust monitors). Provide Hazard Communication to the site construction workers. The workers handling contaminated materials, concrete debris, or soil must be trained to recognize and prevent from exposures to stressors. Proper PPE and training must be required, and decontamination of personnel, excavator, and other equipment must be implemented. Determine the required PPE in the Health and Safety Plan. All appropriate control measures to protect the site workers, base personnel, and the environment must be implemented.

1.2.8 Unforeseen Contamination

Notify the Contracting Officer immediately if contaminated material is discovered that was not previously identified or if other previous

SECTION 02 61 13 Page 3 unforeseen field conditions are discovered.

1.2.9 Scheduling

Notify the Contracting Officer 14 calendar days prior to the start of excavation of contaminated material. The Contractor is responsible for contacting regulatory agencies in accordance with the applicable reporting requirements.

1.2.10 Work Plan

Submit a Work Plan within 30 calendar days after notice to proceed. No work at the site, with the exception of site inspections and surveys, must be performed until the Work Plan is approved. Allow 30 calendar days in the schedule for the Government's review. No adjustment for time or money will be made if resubmittals of the Work Plan are required due to deficiencies in the plan. At a minimum, the Work Plan must include:

a. Schedule of activities.

b. Method of excavation and equipment to be used.

c. Shoring or side-wall slopes proposed.

d. Dewatering plan.

e. Storage methods and locations for liquid and solid contaminated material.

f. Borrow sources and haul routes.

g. Stockpiling.

h. Soil and air monitoring procedure.

i. Sampling and Analysis Plan (The plan must include soil testing, profiling, and waste characterization for disposal).

j. Excess soil disposal plan (The plan must include manifesting, hauling, and disposal facility's acceptance requirements of the soil).

k. Decontamination procedures.

l. Spill contingency plan.

1.2.11 Other Submittal Requirements

Submit separate cross-sections of each area before and after excavation and after backfilling, test results, and two copies of the Closure Report within 14 calendar days of work completion at the site.

1.3 SUBMITTALS

FILL.

SECTION 02 61 13 Page 5

PART 3 EXECUTION

3.1 SURVEYS

A limited soil screening was conducted, and a report is provided in this Section. If the information in the report is deemed insufficient to perform the planned construction, conduct additional soil sampling and analysis.

3.2 EXISTING STRUCTURES AND UTILITIES

No excavation shall be performed until site utilities have been field located. Take the necessary precautions to ensure no damage occurs to existing structures and utilities. Damage to existing structures and utilities resulting from the Contractor's operations shall be repaired at no additional cost to the Government. Utilities encountered that were not previously shown or otherwise located shall not be disturbed without approval from the Contracting Officer.

3.3 CLEARING

Clearing shall be performed to the limits shown on the drawings.

3.4 CONTAMINATED MATERIAL REMOVAL

3.4.1 Excavation

Areas of contamination may be excavated to the depth and extent to complete the project scope unless directed by the Contracting Officer.

Excavation must be performed in a manner that will limit spills and the potential for contaminated material to be mixed with uncontaminated material. An excavation log describing visible signs of contamination encountered must be maintained for each area of excavation. Excavation logs must be prepared in accordance with ASTM D5434.

3.4.2 Shoring

If workers must enter the excavation, it must be evaluated, shored, sloped or braced as required by EM 385-1-1 and 29 CFR 1926 section 650.

Anticipate hazards and conduct necessary monitoring prior to and during work in the excavation.

3.4.3 Dewatering

Dewatering is not anticipated. However, surface water shall be diverted to prevent entry into the excavation. Dewatering shall be limited to that necessary to assure adequate access, a safe excavation, prevent the spread of contamination, and to ensure that compaction requirements can be met.

The dewatering effluent may be discharged back into the ground in close proximity of the construction site as long as any portion of the water does not enter a storm drain, and is not discharged to surface waters.

When there is visible oil, the oil must be removed as much as practical before the water is discharged to the ground. If applicable, Contractor shall prepare a dewatering plan for Government review.

3.5 CONFIRMATION SAMPLING AND ANALYSIS

Utilize all appropriate methods for proper soil management and mitigations, as needed. Appropriate methods include existing

SECTION 02 61 13 Page 6 environmental information (i.e. soil sampling and analysis), visual observation, olfactory examination, field instruments (i.e. PID), and/or field testing.

Confirmation sampling and laboratory analysis are not anticipated at the site since the excavation will be limited to the depth and extent as shown in the design drawings to install new structures and utilities, and the contaminated soil (if present) beyond excavation will remain in place.

Segregate contaminated soil from clean soil and determine the level of engineering controls or PPE to protect site workers and other base personnel.

3.6 CONTAMINATED MATERIAL STORAGE

Contaminated material shall be placed in temporary storage immediately after excavation. Storage units shall be in good condition and constructed of materials that are compatible with the material or liquid to be stored. If multiple storage units are required, each unit shall be clearly labeled with an identification number, and a written log shall be kept to track the source of contaminated material in each temporary storage unit.

3.6.1 Stockpiles

Stockpiles shall be constructed to isolate stored contaminated material, if any, from the environment. Stockpiles shall be constructed to include:

a. A chemically resistant geomembrane liner free of holes and other damage. Non-reinforced geomembrane liners shall have a minimum thickness of 20 mils . The ground surface on which the geomembrane is to be placed shall be free of rocks greater than 0.5 inches in diameter and any other object which could damage the membrane.

b. Geomembrane cover free of holes or other damage to prevent precipitation from entering the stockpile. Non-reinforced geomembrane covers shall have a minimum thickness of 10 mils . The cover material shall be extended over the berms and anchored or ballasted to prevent it from being removed or damaged by wind.

c. Berms surrounding the stockpile, a minimum of 12 inches in height.

Vehicle access points shall also be bermed.

d. The liner system shall be sloped to allow collection of leachate.

Storage and removal of liquid which collects in the stockpile, in accordance with paragraph Liquid Storage.

3.6.2 Roll-Off Units

Roll-off units used to temporarily store contaminated material shall be water tight. A cover shall be placed over the units to prevent precipitation from contacting the stored material. The units shall be located as shown in the approved Work Plan. Liquid which collects inside the units shall be removed and stored in accordance with paragraph Liquid Storage.

3.6.3 Liquid Storage

Dewatering is not anticipated. However, when there is visible oil on dewatering effluent, remove visible oil as much as practical before the

SECTION 02 61 13 Page 7 water is discharged to the ground. Liquid collected from dewatering (i.e.

recovered petroleum free product) or equipment decontamination shall be temporarily stored in 55 gallon barrels, or equivalent. Liquid storage containers shall be water-tight and shall be located as specified in the work plan.

3.7 SAMPLING

3.7.1 Sampling of Stored Material

Surplus soils that will be transported offsite for reuse or disposal must be characterized to ensure compliance with the recipient guidelines and requirements. For soil characterization, collect representative samples by using a multi-incremental sampling technique with a minimum of 50 increments unless the recipient indicates otherwise. Comply with the requirements specified in Section 31 23 00.00 20 EXCAVATION AND FILL. The excess soil must be removed from the installation and disposed of properly in accordance with applicable federal, Guam or local regulations.

Documentation of all analyses must be furnished to the Contracting Officer. The cost for sample analysis and disposal of excess soil and liquid waste is Contractor's responsibility.

3.7.2 Sampling Liquid

Liquid collected from dewatering and decontamination must be sampled at a frequency of once for every 500 gallon of liquid collected or the sampling frequency required by the disposal facility. Samples must be tested for Guam and Federal criteria and analytes required by the disposal facility.

Liquid waste must be disposed of or treated at offsite permitted facilities. The cost for sample analysis and disposal of liquid waste is the Contractor's responsibility. Documentation of all analyses must be furnished to the Contracting Officer.

3.7.3 Sampling Beneath Storage Units

If the storage unit (i.e. stockpile) is located within the unpaved area, soil samples from beneath each storage unit must be collected prior to construction of and after removal of the storage unit. Samples must be collected at a frequency of one per every 100 square yards from a depth interval of 0 to 0.5 feet by using a multi-increment sampling method and shall be tested for the following:

* Total Petroleum Hydrocarbons-Diesel Range Organics and Residual Range Organics (TPH-DOR/RRO) by EPA Method 8015B

* 18 priority polycyclic aromatic hydrocarbons (PAH) by EPA Method

8270C-SIM

* RCRA 8 metals by EPA Method 6010/7000

* Pesticides by EPA Method 8081

Certify soil analytical results obtained after removal of the storage unit are not significantly greater than the initial soil analytical results collected prior to construction of the storage unit. The post-construction soil results must not exceed 120% of the initial analytical results obtained prior to using the storage area. If the storage area is located within the paved area, no soil testing will be required. However, geomembrane liners must be placed in accordance with 3.6.1 Stockpiles.

SECTION 02 61 13 Page 8

Based on test results, soil that has become contaminated above action levels or significantly higher than initial testing results (exceeding 120% of the initial analytical results) must be removed at no additional cost to the Government. Contaminated material that is removed from beneath the storage unit must be handled in accordance with the paragraph Sampling of Stored Material. As directed by the Contracting Officer and at no additional cost to the Government, additional sampling and testing must be performed to verify areas of contamination found beneath stockpiles have been cleaned up to below action levels or initial testing results .

3.8 SPILLS

In the event of a spill or release of a hazardous substance (as designated in 40 CFR 302 ), pollutant, contaminant, or oil (as governed by the Oil Pollution Act (OPA), 33 U.S.C. 2701 et seq.), notify the Contracting Officer immediately. If the spill exceeds the reporting threshold, follow the pre-established procedures as described in the Base Wide Contingency Plan for immediate reporting and containment. Immediate containment actions shall be taken to minimize the effect of any spill or leak.

Cleanup shall be in accordance with applicable federal, state, and local regulations. As directed by the Contracting Officer, additional sampling and testing shall be performed to verify spills have been cleaned up.

Spill cleanup and testing shall be done at no additional cost to the Government.

3.9 BACKFILLING

3.9.1 Confirmation Test Results

Excavations shall be backfilled immediately after all contaminated materials have been removed and confirmation test results have been approved. Backfill shall be placed and compacted to the lines and grades shown on the drawings.

3.9.2 Compaction

All backfill operations must adhere to Section 31 23 00.00 20 EXCAVATION
