Attachment 5.2 - B400 HTRW.pdf

2021 Wake Island HTRW Survey

Facility: 400 Condition: Significantly Damaged Former Dining Facility Utilization: Mostly abandoned, one section is in use (as storage) Currently Hazardous Storage, Base Size: 8,200 Square Feet Year Built: Unknown

Construction: Asbestos roof panels and transite wall boards. Building is severely storm damaged. All electrical systems are destroyed, and large areas of the roof structure are missing.

Remaining walls are in reasonably good condition; however, some areas are cracked and broken. Large areas of roof are completely missing. Building has been marked for demolition.

Chugach Environmental Department has asked to continue using this facility as a Hazardous Waste Storage Facility. To continue use of this facility for this purpose, certain upgrades should be accomplished to bring the facility into compliance with Fire and Life Safety Codes and Environmental requirements for a facility of this type. These would include adequate fire alarm/suppression systems, containment systems, forklift access, electrical and lighting systems. Because portions of the roof remain relatively intact and able to provide at least some shelter from rain, and the building is located away from more populated areas, continuing to use this facility as a Hazardous Waste Facility should pose no inordinate hazards and is better than storing hazardous materials outside. Current materials being stored here include:

HAZMATs, empty barrels and containers. A map of the building location can be seen in Appendix 1.

Building 400

Number of Stories: 1 Heat System Type: None Fuel Tanks: N/A PCB Painted Concrete: N/A Concrete in Foundation/Walls: 297 Cubic Yards Other Debris: 1,715 Yards

Asbestos Found in Building 400 (estimated quantities)

Transite Roofing and Panel Sealant: 17,071 Square Feet Skim Coat: 3,038 Square Feet TSI Tank Insulation: 70 Linear Feet TSI Fittings: 15 Each Floor Tile and Mastic: 3,008 Square Feet TSI Pipe: 160 Linear Feet

It appears that abatement had begun and then was abandoned.

Asbestos samples were not collected in 2021. Results from 2007, 2010, and 2016 are provided in Appendix 4.

Lead and PCB Paint Found in Building 400 (estimated quantities)

LBP or coatings were identified in the following:

Exterior Walls 3,038 Square Feet Door Frame 21 Square Feet Sink 1 Each Joist 9,381 Square Feet

The following table shows paint samples collected in 2021 and analyzed for lead, toxicity characteristic leaching procedure (TCLP) lead, and polychlorinated biphenyls (PCBs). Complete 2021 results are provided in Appendix 3.

Sample # Location Lead

(total, mg/kg) TCLP Lead (mg/L)

PCBs (mg/kg)

Regulatory value: 5,000 5 50 W0400‐001LP white/green paint 116 NA ND W0400‐002LP dark green foundation 228 NA 0.631 W0400‐003LP tan interior paint 6,860 NA 0.213 W0400‐004T white/green paint (TCLP) NA 0.381 NA

ND ‐ Non‐Detect NA ‐ Not Analyzed Highlighted cells exceed corresponding regulatory value

One TCLP sample was collected from the representative waste stream and results were 0.381 mg/L, which is lower than Resource Conservation and Recovery Act (RCRA) landfill limits.

Toxicity characteristic for lead is defined in 40 CFR 261.24.

Overall, PCBs in paint do not appear to be an environmental concern. Paint on metal does not constitute a leachability hazard and therefore all metal materials with PCB amended paint can be readily landfilled in an EPA permitted landfill per 40CFR 761.62(b). The highest concentration of total PCBs from the 2021 sampling events was 0.631 mg/kg (2021 Sample ID W0400‐002LP).

XRF results from 2010 are provided in Attachment 4.

Other Potentially Hazardous Materials found in Building 400 (estimated quantities)

Technical Information

Preparation/Analytical Method Verification All samples and QC in this batch were cleaned using alumina in order to remove oil and other high molecular weight interferences. All samples and QC in this batch were cleaned with activated copper in order to remove sulfur. All reported analyte detections in client and quality control samples were within the established retention time windows. Reported analyte concentrations were confirmed on dissimilar columns.

Sample Dilutions Samples 536268006 (W0202-003LP) and 536268018 (W443-001LP) were diluted due to high concentrations of target analytes in the samples. Samples 536268002 (W0130-002LP), 536268003 (W0130-003LP), 536268010 (W0400-002LP) and 536268011 (W0400-003LP) were diluted due to high level of non-target analytes within the retention time window of interest.

Miscellaneous Information

Manual integrations Samples 1204768631 (LCS), 1204768632 (LCSD), 536268004 (W0202-001LP), 536268006 (W0202-003LP), 536268009 (W0400-001LP), 536268010 (W0400-002LP), 536268011 (W0400-003LP), 536268016 (W0404-002LP), 536268017 (W0404-003LP), 536268018 (W443-001LP) and All required manual integration to correctly position the baseline as set in the calibration standard injections.

Additional Comments The lower results from either column have been chosen and reported in the data package for the client samples, MB and LCS. The data reported for the MS/MSD are from the same analytical column as the parent sample.

The samples in this SDG were analyzed on an "as received" basis.

Data Summary:

All sample data provided in this report met the acceptance criteria specified in the analytical methods and procedures for initial calibration, continuing calibration, instrument controls and process controls where applicable, with the following exceptions.

Calibration Information

ICSA/ICSAB Statement For the ICP-MS analysis, the ICSA solution contains analyte concentrations which are verified trace impurities indigenous to the purchased standard.

Continuing Calibration Blanks (CCB) Requirements All continuing calibration blanks(CCB) bracketing the sample in this SDG did not meet the acceptance criteria for lead. The samples bracketed by this CCB, however, contained the element with a concentration at least ten times greater than the concentration in the CCB. This indicates that any contribution to the concentration of these elements in the samples from potential laboratory contamination would be minimal. ICP-MS.

Quality Control (QC) Information

MS/MSD Relative Percent Difference (RPD) Statement The RPD values between qualifying analyte results in the MS and MSD were not within the acceptance limits. Sample non-homogeneity and/or possible matrix interferences may be suspected.

Sample Analyte Value

1204764211MS and 1204764212MSD (W0130-002LP) Lead RPD 64.7* (0%-20%)

Technical Information

Preparation/Analytical Method Verification Method SW-846 3050B is not a total digestion technique for most samples. It is a very strong acid digestion that will dissolve almost all elements that could become environmentally available. By design, elements bound in silicate

Page 506 of 724 SDG: 536268 structures are not normally dissolved by this procedure as they are not usually mobile in the environment.

Extraction Process Statement Less sample was used due to limited sample mass. Proportional amounts of sample and extraction fluid were used as prescribed by the method. 536268008 (W0306-001T).

Sample Dilutions Dilutions may be required for many reasons, including to minimize matrix interferences or to bring over range target analyte concentrations into the linear calibration range. Samples 536268002 (W0130-002LP), 536268003 (W0130-003LP), 536268004 (W0202-001LP), 536268006 (W0202-003LP), 536268011 (W0400-003LP), 536268016 (W0404-002LP), 536268019 (W443-002LP) and 536268020 (W443-003LP)-ICP-MS were diluted to ensure that the analyte concentrations were within the linear calibration range of the instrument. The ICPMS solid samples in this SDG were diluted the standard two times. ICP-MS.

GEL requires all analytical data to be verified by a qualified data reviewer. In addition, all CLP-like deliverables receive a third level review of the fractional data package.

The following data validator verified the information presented in this data report:

The Qualifiers in this report are defined as follows:

B Target analyte was detected at > 1/2 LOD and > 1/10 the amount in any sample. For common laboratory contaminants, no analyte detected > LOQ.

J Indicates an estimated value. The result was greater than the detection limit, but less than the reporting limit or indicates that the analyte recovery in the MS or MSD is outside of specified acceptance criteria.

U Indicates the target analyte was analyzed for but not detected above the detection limit.
