PART 2 - PRODUCTS

2.1 ADEC Approved Work Plan

A. CONTRACTOR shall engage an Environmental Sub-consultant (QEP) to prepare a Work Plan governing any earth disturbing activities necessary to complete project scope. The Work Plan shall be provided as a Pre-Draft document for a 10 working day DEPARTMENT review. Following incorporation of any DEPARTMENT comments or suggestions, the CONTRACTOR or QEP will provide the Draft Work Plan to ADEC for review. It should be anticipated that this will take a minimum of 30 calendar days.

Following agreement on any changes suggested by ADEC with DEPARTMENT approval, the CONTRACTOR or QEP will submit the Final Work Plan to ADEC and the

DEPARTMENT.

2.2 QEP Field Monitoring

A. The QEP shall provide direct field observation of earth disturbing activities covered by the Work Plan to monitor that agreed construction practices and contaminated material handling practices related to ADEC regulated activities are followed in accordance with the ADEC approved Work Plan.

03/14/2022 02 61 13 - 2

2.3 After-Action Report

A. Following field work governed by the ADEC approved Work Plan, the QEP shall prepare an ADEC compliance (18 AAC 75) After-Action Report documenting field activities performed in relation to the Work Plan. Report review will occur as detailed in Section

2.1 (A) of this specification for the Work Plan. Certificates of Disposal (COD) shall be included with this report per Section 3.4 (C).

PART 3 - EXECUTION

3.1 GROUND DISTURBING ACTIVITIES

A. Ground disturbing activities shall be limited to the greatest extent possible and onsite reuse of excavated material shall be prioritized per Section 3.4 (B). If offsite transport and disposal are proposed, Section 3.4 (C) shall be followed along with the ADEC approved Work Plan.

B. Field tasks will be monitored by an approved qualified environmental professional (QEP), as defined in 18 AAC 75.333, and as identified in the ADEC approved Work Plan.

The QEP will be supplied by the DEPARTMENT.

C. Volumes of solid contaminated materials will be estimated as CUBIC YARDS in the field, TONS as measured by the disposal facility if shipped for offsite disposal, and in gallons for liquid materials. Measurement methods for determining quantities shall be approved by the DEPARTMENT prior to use.

3.2 DEWATERING REQUIREMENTS

A. Should groundwater be encountered during the excavation, Contractor shall implement an ADEC-approved dewatering plan for treatment and disposal. Groundwater is estimated to be present at twenty (20) to twenty-five (25) feet below existing grade and three (3) to five (5) feet below existing grade based on investigations at adjacent properties in Cold Bay and Kodiak, respectively.

3.3 CONFIRMATION SAMPLING OF CONTAMINATED SOIL AND OPEN EXCAVATION

A. Excavated soil shall be containerized and/or temporarily stockpiled on the site. The approved QEP shall collect samples of the stockpiled material for laboratory analysis and conduct confirmation sampling of the side walls and floor of the excavation.

Stockpiles shall only be sampled if offsite disposal is proposed. Section 3.4 (A) shall be used if onsite reuse is proposed. These procedures shall be detailed in the ADEC approved Work Plan.

B. The Work Plan shall specify that contamination will not be “chased” only ground disturbing activities necessary to complete this project scope shall be assumed. This provision is subject to approval by ADEC during the Work Plan review process.

03/14/2022 02 61 13 - 3

3.4 ON-SITE MANAGEMENT OF CONTAMINATED SOILS

A. Temporarily stockpiled contaminated soils that are to be returned to their original location on site will be managed in a manner compliant with ADEC regulations and guidance. Generally, soil will be temporarily stockpiled on a lined containment area, covered and flagged. The approved QEP shall collect samples of the stockpiled material for laboratory analysis.

B. If testing results (Section 3.3 [A]) indicate that stockpiled soils are not contaminated with project contaminants of concern above ADEC cleanup levels, the soil shall be used as backfill on site if soils meet backfill specifications under Specification Section 31 20 00 Earth Moving

C. Contaminated soils shall be containerized, transported, and disposed of off-site in accordance with project requirements following written ADEC approval. The CONTRACTOR shall provide Certificates of Disposal (COD) from the disposal facility to the DEPARTMENT.

3.2 PERSONNEL PROTECTION PROCEDURES

A. Initial Determination: An initial determination is required in the absence of acceptable prior exposure data in accordance with 29 CFR 1926.62. Establish an initial lead work area for each material to be disturbed and each disturbance procedure if required.

Isolate these lead work areas from the rest of the building. Personnel working in these areas shall wear respiratory protection and personal protective equipment as directed by the IH. Perform personal and work area air monitoring as directed by the IH.

Operational decontamination facilities shall be available. Work performed shall be representative of the work to be done during the remainder of the project.

B. Respirator Evaluation: Upgrading, downgrading, or not requiring respirators shall be recommended by the Contractor's IH based on the measured airborne lead-containing dust or fume concentrations. Immediately implement recommendations to upgrade the respiratory protection, followed by notification to the Department. NOTE: Submit recommendations in writing to downgrade respirator type or not require respirators to the Department for review and written approval prior to implementation.

C. Decontamination Procedures: Worker and material decontamination procedures shall be as described in the Contractor’s approved work plan. Worker decontamination shall be as directed by the Contractor’s competent person.

Work Stoppage: Stop work if the IH, the Department, or a representative of a regulatory agency determines that the work is not in compliance with the Contractor's approved work plan, these specifications, or applicable laws and regulations. The Contractor shall stop work and notify the Department whenever the measured concentrations of lead outside the lead control area equal or exceed 30 µg/m3 for airborne lead or 100 µg/ft2 for lead dust on surfaces outside of the work area. When such work stoppage occurs, the cause of the contamination shall be corrected, and the damaged or contaminated area shall be restored to its original decontaminated condition by the Contractor at no expense to the Department. The Contractor is responsible for removing dusts and debris that were generated as a result of his work.

C. Perform dust wipe sampling for each lead work area without a negative initial determination. Include at least one sample immediately outside the entrance to the work area daily.

D. Take personnel samples in accordance with 29 CFR 1926.62. Personal samples for an employee will include a minimum of two samples per 8-hour shift. Employees will be monitored at the rate of at least one employee for every eight people performing each task in each work area. Persons performing separate tasks or in separate lead work areas shall be sampled separately.

E. Reduction of monitoring: For each operation for which the Negative Initial Determination established workers’ exposure will be below the action level, the Contractor’s IH may petition the Department to recommend that the monitoring as required above be reduced for the specific task or operation.
