1.0 INTRODUCTION

Environmental Science Corporation (ESC) was tasked by AECOM conduct a site investigation for surveying hazardous materials in order to support the design analysis for the project “FY24 Repair of Pier 237, 341, and 516, Yokohama North Dock, Yokohama, Japan” awarded to AECOM. This project is for U.S. Army Corps of Engineers, Japan District (JED) under the contract number

W912HV19D0006.

The objective of site investigation is to identify and to collect samples of suspicious hazardous materials located on Piers 237, 341, and 516. Some structural and non-structural deficiencies to be repaired or replaced may present hazardous materials in their composition and may require special care in case of disturbance during repair or removal. Our hazardous material (hazmat) investigation was conducted on accessible portions of the piers that consist of the edge of piers to the external area of buildings facing the sea. In this hazmat investigation, ESC collected samples and delivered them to a qualified analytical laboratory where the material samples were analyzed for asbestos containing material (ACM) and lead-based paint (LBP).

In addition, other potentially hazardous materials such as polychlorinated biphenyl (PCB), mercury in fluorescent and high-intensity discharge (HID) light bulbs and/or thermostats, radioactive materials such as those found in smoke detectors and/or other regulated hazardous substances were surveyed by visual inspection and included in this report.

The layout of piers showing sample locations and photos of samples collected during the site investigation for ACM and LBP are provided in Appendix A and B, respectively.

2.0 HAZARDOUS MATERIAL INVESTIGATION

ESC conducted a visual inspection and collected samples of suspicious hazardous material from structural and non-structural components located on Piers 237, 341 and 516 from 11 to 18 July 2022. Based on the visual inspection on the site, these suspicious materials were assumed to potentially contain asbestos or lead based paint. A total of 54 samples were collected for ACM analysis and 20 samples collected for LBP analysis. Samples were delivered to and analyzed by SGS Forensic Laboratories, a qualified analytical laboratory. Laboratory certifications are included in Appendix D.

Laboratory analysis results samples and chain-of-custody (COC) forms for ACM and LBP are provided in Appendix A and B, respectively. Inspector certifications are also provided in Appendix E.

An additional investigation was carried out at Piers 341 (Berth A, B, HC 1, 3, and 5), and 516 (Berth D, E, G, H, J, and L) on 2 November 2023. During this additional survey, ESC collected an additional seventeen (17) asbestos bulk samples, and three (3) paint chip samples for metals analysis.

2.1 ASBESTOS SURVEY AND SAMPLING METHODS/ANALYSIS

The Japan Environmental Governing Standards (JEGS) defines ACM as material that contains equal to or greater than 0.1% asbestos by weight (USFJ, 2018). The laboratory analyzed the bulk samples for asbestos content by PLM with EPA Method for the Determination of Asbestos in Bulk Building Materials (EPA, 1993). The PLM method has a limit of quantification of 1.0% asbestos, above the JEGS regulatory limit of 0.1%. However, the PLM method limit of detection is less than 0.1%. PLM can detect asbestos below 1.0% and the JEGS limit of 0.1% but cannot quantify the exact concentration. A PLM result of ‘trace’ indicates that asbestos was detected in the sample at a concentration below 1.0%, however the concentration cannot be quantified. Per the JEGS, all ‘trace’ results must be assumed to be greater than 0.1%, and thus ACM, unless the sample is re-analyzed by a method with a limit of quantification less than 0.1%, such as 1000-point counting.

Suspected ACM samples were collected and analyzed by SGS Forensic Laboratories under COC for analysis by PLM method. Table 1 summarizes all results of samples showing the location, condition of material, quantities and properties of suspect ACM referring to laboratory analysis results included in the Appendix A. Analytical results greater than the JEGS regulatory limit of 0.1% asbestos are highlighted in red.

Two (2) out of seventy-one (71) samples analyzed by PLM indicated asbestos content higher than 0.1% related to joint sealant material located on Pier 341 and 516. This ACM material quantity is estimated to be 10,500 m2 and was observed to be in moderately damaged condition. Further action is required if this material is to be disturbed or removed.

No trace results were identified during the laboratory analysis.

Friable = When a dry sample result of a work process can be reduced to powder by hand pressure

Nonfriable = When a dry sample is not crumbled, pulverized or reduced to powder by hand pressure

See below for additional comments on specific materials.

Additional descriptors are provided for sampled materials as follows:

Joint Sealant

Black joint sealant was observed throughout all three piers at expansion joints between concrete slabs. Black joint sealant was also observed to be in use for crack repairs. Because the repair history of the piers and installation dates of the crack repair sealant could not be confirmed, this sealant has been treated as a single homogeneous material.

New Concrete and Concrete (Old)

Deck concrete at Piers 341 and 516 was observed to be comprised of two separate types of concrete, designated as “New” and “(Old)” in this report. New concrete is lighter in color with no exposed aggregate. Old concrete was darker in color with visible aggregate. An example indicating the difference between new and old concrete is provided in Figure 1. New concrete was observed on the pier decks at various locations throughout Piers 341 and 516.

Yokohama North Dock, Yokohama, Japan 7 ESC 8227

Figure 1. Typical condition and arrangement of new concrete (lighter in color) and old concrete (darker in color)

Nose Mortar

The term “nose mortar” is used in this report to describe mortar located below stone nose blocks at the edges of Pier 341 at Berths A and B and at Pier 516 at Berths C through E. Figure 2 shows the arrangement of the pier edge nose blocks and mortar underneath. Note that in other reports this material may also be referred to as grout, but the term nose mortar is used in this report.

Figure 2. Nose mortar location at edge of pier (typical).

Tile Mortar

The term “tile mortar” is used in this report to refer to mortar between stone pavers in the sloped berthing platforms at Pier 341 Berths HC2, HC3 and HC4 and Pier 516 Berths I and K. Figure 3 shows the arrangement of the pier edge nose blocks and mortar underneath. Note that in other reports this material may also be referred to as grout, but the term tile mortar is used in this report.

Figure 3. Tile mortar location at sloped berthing platform (typical).

Mortar

On all three piers, mortar has been used to patch cracks in the deck concrete, especially in the vicinity of wheel stops. The term “mortar” is used to refer to this material.

Grey Sealant

Grey sealant was observed at Pier 341 and used as sealant between the deck slab and utility pits at Berths A and B.

2.2 LEAD SURVEY AND SAMPLING METHODS/ANALYSIS

The LBP survey and report were conducted in accordance with EPA guidance (40 CFR Part 745) and JEGS (USFJ, 2020). LBP is defined as paint or other surface coatings that contain lead equal to or greater than 1.0 milligram per cm2 or 0.5 percent by weight.

Paint chip samples were collected in accordance with ASTM E1729-05, Standard Practice for Field Collection of Dried Paint Samples for Subsequent Lead Determination (ASTM, 2005).

The samples were delivered to SGS Forensic Laboratories under chain of custody for analysis by EPA Method 3050B/7000B, Atomic Absorption Spectroscopy (EPA, 1996). Laboratory reports are included in Appendix C.

Lead-containing paint (LCP) is paint containing detectable concentration of lead, but not at sufficient concentration to be classified as LBP. JEGS (USFJ, 2020) defines LCP paint or other similar surface coating materials containing lead or lead compounds in which the lead content (calculated as lead material) is more than 0.009 percent by weight of the total nonvolatile content of the paint of the weight of the dried paint film. The concentration of lead for LCP is less than the maximum permitted concentration of lead and therefore, no special treatment is required for disposing these materials.

Yokohama North Dock, Yokohama, Japan 9 ESC 8227

It should be noted that Government of Japan (GOJ) regulatory limit for lead as a specially controlled industrial waste is 0.3 milligrams per liter (mg/L) for waste sludge, acid, and alkali, as determined by toxicity characteristic leaching procedure (TCLP) laboratory analysis.

Table 2 summarizes the sample test results and their respective classification based on the concentration of lead referring to the laboratory analysis results and LBP sampling location plan are included in the Appendix B. For the samples in red text were identified as LBP.

Based on the laboratory analysis results, eight (8) out of fifteen (15) samples presented lead concentration greater than 0.5 percent by weight and are classified as LBP. These LBP samples were collected from fiberglass wheel stops and metal bollards located on the Piers 237, 341 and

516. Four (4) other samples presented lead concentrations meeting the definition of LCP. These LCP samples were collected from metal bollards located on Pier 237 and painting on the concrete wheel stop and concrete pavement located on Pier 341.
