Geotechnical and Environmental Sediment Sampling Eisenhower Mooring Area and SLSDC Marine Base Mooring Area – Massena, NY

St. Lawrence Seaway Development Corporation (PH Project #1896.001) September 2019

Princeton Hydro, LLC Page | 1

INTRODUCTION

Princeton Hydro, LLC (Princeton Hydro) was contracted by the Saint Lawrence Seaway Development Corporation (herein after referred to as “SLSDC”) to complete an environmental assessment of the sediment within the Wiley-Condero Canal. The project area consists of two (2) individual sites located within the canal, which is situated approximately 5 miles northeast of the Town of Massena within St. Lawrence County, New York.

The first individual site within the Canal is the at the SLSDC Marine Base, which is a tug/mooring area directly southwest of Snell Lock. The second location is directly northeast of the Eisenhower Lock, which is also used as a mooring area.

It is our understanding that both of these sites require dredging in order to maintain mooring access for boat traffic navigating the channel. To facilitate the dredging process, the SLSDC requested that fourteen (14) sampling locations be explored to develop an understanding of the analytical and physical characteristics of the sediment that is to be dredged. The following locations were sampled under this contract:

• Ten (10) environmental sampling locations were tested within the Canal at the Marine Base;

• One (1) geotechnical test boring was completed approximately 3 ft off of the sheetpile wall at the Marine

Base; and

• Three (3) environmental sampling locations were tested within the Canal at the Eisenhower Lock

This report provides an overview of the field operations, observed in-field conditions, and summary of the laboratory test results to facilitate dredging of the Wiley-Condero Canal.

1. FIELD EFFORT

Princeton Hydro subcontracted Atlantic Testing Laboratories (ATL) to assist with the performance of the sediment sampling effort. The boring locations were accessed by a pontoon/work boat owned and operated by ATL, with client-provided coordinates utilized in order to locate the sampling locations. All sampling locations were located via the use of a Trimble GeoExplorer 2008 series GPS unit, owned and operated by ATL. The sediment samples were obtained with a Rossfelder P-3 Underwater Vibracorer with a 4-inch diameter metal core tube attached.

The metal core tube was lined with an expendable rigid plastic liner at each boring location to extract the collected sediments and facilitate the sampling process.

1.1: ENVIRONMENTAL BORINGS

On August 6th, 2019, Princeton Hydro mobilized to the Marine Base site to perform the logging and sampling of Vibracore samples to facilitate the proposed dredging at the two SLSDC project sites. On this date, borings B-5, B-6, B-7, B-8, B-9, B-10, B-11, and B-12 were completed. Borings B-1, B-2, B-3, B-13, and B-14 were completed on August 7th, 2019. A map detailing all sampling locations can be found within Appendix A to this report.

1.1.1: SEDIMENT COLLECTION, LOGGING, AND SAMPLING EFFORT

Upon arrival at each boring location, the boat was anchored in-place via mechanical spuds, and the water depth was measured prior to sampling activities. After the water depth was recorded, GPS coordinates of each sampling location were recorded with the aforementioned GPS unit. The Vibracore was lowered until contact with the mudline was encountered, where it was then advanced into the underlying sediment to depths of 6.0 feet below the mudline (B-1, B-2, B-3) or 4.0 feet below the mudline (B-5, B-6, B-7, B-8, B-9, B-10, B-11, B-12, B-13, B-14) as per the approved Work Plan.

Princeton Hydro, LLC Page | 2

Upon reaching the appropriate depths below the mudline, the Vibracore was mechanically lifted onto the deck of the boat and a plastic cap was immediately placed onto the bottom of the rigid plastic liner to protect the collected sample. The plastic liner was extracted from the metal casing, and the top of the liner was capped. Recovery of sediment within the plastic liner was recorded, and the caps were sealed to the plastic liner with duct tape. It should be noted that a new plastic liner and new caps were used at each boring location.

Logging and sampling of the material was performed on-shore at the Marine Base facility by Princeton Hydro. Sampling efforts were conducted in accordance with the NYSDEC Technical & Operational Guidance Series (TOGS) 5.1.9. The recovered sediment was logged in accordance with ASTM D2488.

Equipment was decontaminated prior to sampling with a soapy water solution, 10% nitric acid solution, and a methanol solution. Deionized water was used to rinse the equipment between each decontamination solution. Archive samples within Elevation 180.0 to 179.5 ft were obtained from each plastic sample liner. This was achieved by measuring from the top of the Vibracore sample (the mudline elevation as provided by ATL) to the specified elevation. Subsequent to collection of this archive sample, the remaining sediment was homogenized/composited and sampled for the analytical laboratory analysis of the following parameters:

• Metals;

• PAH’s and Petroleum Related Compounds;

• Pesticides;

• PCB’s;

• Dioxins;

• Grain Size; and

• Total Organic Carbon.

In addition to the analytical samples detailed above, the following samples were obtained to comply with all Quality Control Procedures outlined in TOGS 5.1.9:

• One (1) duplicate sample to check laboratory and field procedures;

• One (1) equipment rinse blank to check field decontamination procedures; and

• One (1) matrix spike and one (1) matrix spike duplicate as required by laboratory protocols.

Boring logs detailing the water depth, mudline depth and elevation, sediment classification, sample identification, material resistance, and termination depth and elevation were completed and are included within Appendix B. These recordings are provided below within Table 1 (below).

1.2: GEOTECHNICAL BORING

On August 7th, 2019, Princeton Hydro observed the advancement of the geotechnical boring (B-4) at the Marine Base site. The boring location was identified in the field by measuring 80 feet east from the western-most sheetpiling corner. The boring was advanced by way of a SPT-equipped CME-55 tracked drill rig, owned and operated by Atlantic Testing Laboratories. A wooden platform was constructed and attached to the drill rig to facilitate the drilling operations. The boring was performed 3-feet north of the existing sheetpiling, and was advanced through the underlying riprap to an elevation of 173.3 ft IGLD85 (i.e., 11 ft below bottom of riprap).

1.2.1 DRILLING PROCEDURE, LOGGING, AND SAMPLING EFFORT

The boring was completed utilizing 6-inch hollow stem augers, rotary advanced in accordance with ASTM D1452. A cutterhead attachment was utilized to advance the boring through the existing riprap material.

Split-spoon sampling was completed continuously until the boring termination depth was achieved (elevation 174 ft). Samples were logged and collected by a Princeton Hydro geologist utilizing USCS classification and description techniques (ASTM D2488). Split-spoon samples were collected into air/moisture tight sample jars during the boring operations. All collected samples were delivered to our Sicklerville (NJ) AASHTO accredited facility for materials testing.

A boring log detailing the water depth, material classification and stratification, sample depths, blow counts, and termination depth is attached within Appendix B.

2. LABORATORY ANALYSIS AND RESULTS

Princeton Hydro subcontracted Alpha Analytical Laboratories (herein after referred to as “Alpha Analytical”) for the testing of the requested analytical parameters in accordance with NY TOGS 5.1.9. The environmental samples were placed into air-tight sample jars with Teflon lined caps supplied by Alpha Analytical. Each jar was labeled

Princeton Hydro, LLC Page | 4 with their respective sample identification, placed within an ice filled cooler, and logged on a Chain of Custody form. Samples were picked up on-site at the Marine Base by Alpha Analytical.

The following table outlines the analytical parameters that were analyzed by Alpha Analytical.

The analytical parameters were tested in accordance with methods prescribed within the NY TOGS 5.1.9 guidelines. It should be noted that the threshold values utilized for the laboratory analysis are based off of Table 21 within the TOGS 5.1.9 guidelines. These threshold values are further categorized into three (3) classes of quality.

The following definitions of the designation Class is taken directly from Section III of the TOGS 5.1.9:

Class A: No Appreciable Contamination

No toxicity to aquatic life. If sediment chemistry is found to be at or below the chemical concentrations which define this class, dredging and in-water or riparian placement, at approved locations, can generally proceed.

Class C: High Contamination

Acute toxicity to aquatic life. Class C dredged material is expected to be acutely toxic to aquatic biota and therefore, dredging and disposal requirements may be stringent. When the contaminant levels exceed Class C, it is the responsibility of the applicant to ensure that the dredged material is not a regulated hazardous material as defined in 6NYCRR Part 371. This TOGS does not apply to dredged materials determined to be hazardous. Questions regarding hazardous waste, should be referred to the Department’s Division of Environmental Remediation.

The following sections detail the concentration and subsequent quality class in accordance with Table 2 of the

TOGS 5.1.9:

1 Table 2: Sediment Quality Threshold Values for Dredging, Riparian, or In-Water Placement, page 21, NYSDEC TOGS 5.1.9, November 2004

Class B: Moderate Contamination

Chronic toxicity to aquatic life. Dredging and riparian placement may be conducted with several restrictions. These restrictions may be applied based upon site-specific concerns and knowledge coupled with sediment evaluation.

2.7 SUMMARY

The environmental/analytical laboratory testing revealed that the majority of the tested parameters place the sediment within the Class A threshold category.

METALS

Metals within the collected sediment were analyzed for concentrations of Arsenic, Cadmium, Copper, Lead, and Mercury. While metals occur in ecosystems, their concentrations vary based off of geology and site-specific conditions and can become toxic at certain levels2. The NYTOGS 5.1.9. targets the presence of Arsenic, Cadmium, Copper, Lead, and Mercury as it’s five (5) impactful metals. The Class A threshold values were compared to the laboratory results as follows: Arsenic: 14 mg/kg, Cadmium: 1.2 mg/kg, Copper: 33 mg/kg, Lead: 33 mg/kg, and Mercury: 0.17 mg/kg. All metal concentrations fell within Class A, with exception for the Lead concentration within B-2 (63.6 mg/kg).

PAH’S AND PETROLEUM RELATED COMPOUNDS

The presence of PAH’s (Polycyclic Aromatic Hydrocarbons) and Petroleum Related Compounds were determined by the Total PAH within each sediment sample. PAH’s occur naturally within coal, crude oil, and gasoline, and are also produced during their combustion. Based off of the laboratory analysis, there were no concentrations of Petroleum Related Compounds or Total PAH levels that exceeded the parameters of the Class A threshold (less than 4.0 mg/kg). The highest concentration of PAH’s were found within B-6 (0.58401 mg/kg), which was 3.41599 mg/kg below the upper boundary of Class A material.

BENZENE AND BTEX

The sediment samples were analyzed for Benzene, Tolulene, Ethylbenzene, p/m/-Xylene, o-Xylene, and Benzene. BTEX is the sum of Benzene, Tolulene, Ethylbenzene, and Xylene concentrations, and is a general indicator of petroleum contamination within sediment. No detectable levels of Benzene or BTEX were found during the laboratory analysis.

PESTICIDES

The presence of Pesticides within the sediment samples were determined by the analysis of Mirex, Chlordane, Dieldrin, and the sum of DDT, DDD, and DDE. These pesticides are no longer used for agricultural purposes, but can still be present in the environment from historical use. The laboratory testing did not detect levels of Dieldrin or Chlordane, which results in a Class A threshold classification. The testing revealed that the DDT concentration within B-2 fell within Class B, with a total DDT, DDD, and DDE concentration of 0.00915 mg/kg. All other detections of pesticides fell within the Class A threshold value.

CHLORINATED HYDROCARBONS (PCB’S)

The presence of PCB’s (polychlorinated biphenyls) within the sediment samples were determined by the sum of Arochlor concentrations. PCB’s were primarily used within electrical equipment, hydraulic fluids, head transfer fluids, lubricants, and plasticizers3. Manufacturing with the use of PCB’s was discontinued in 1979, but they do not readily break down once exposed to the environment. The laboratory testing focused on the presence of nine (9) Arochlors, which is the most common PCB mixture and is what the TOGS 5.1.9. bases PCB concentrations from. The testing revealed that the Arochlor 1260 concentration within B-2 fell within Class B, with a total PCB concentration of 0.1267 mg/kg. All other detections of PCBs fell within the Class A threshold value.

Princeton Hydro, LLC Page | 16

DIOXINS

Dioxins within the sediment samples were determined by the level of 2,3,7,8-TCDD (2,3,7,8,- Tetrachlorodibenzo-p-dioxin) concentrations, which is considered to be the most toxic of all dioxin chemical structures4. Dioxins are not directly produced or used currently, but rather form as a byproduct of combustion processes (waste incineration, fuels etc.) and the production of chlorinated organic compounds. Dioxins break down very slowly in the environment, with most of their concentrations coming from releases that occurred decades ago. The NYTOGS 5.1.9. bases the sediment quality threshold off of 2,3,7,8-TCDD concentrations, with 0.0000045 mg/kg (4.5e-6) set as the limit for Class A. The highest concentration of 2,3,7,8,-TCDD was found within B-6 (0.000000668 mg/kg (6.68e-7)). Based off of the laboratory analysis, the Dioxin concentrations fell within the Class A threshold value.

3.1 SUMMARY OF PHYSICAL PARAMETER TESTING OF ENVIRONMENTAL SAMPLES

Sediment at the Marine Base site consists primarily of Sand-Silt-Clay mixtures in varying amounts, including Lean Clay (CL), Lean Clay with Sand (CL), Sandy Silty Clay (CL-ML), Clayey Gravel (GC), Silty Clayey Sand with Gravel (SC), and Silty Clayey Sand with Gravel (SC-SM). The fines within the sediments were generally cohesive in nature.

Vibracore samples collected in the field indicate that the materials encountered have an increasing gravel content with depth.

Sediment at the Eisenhower Lock site also consists primarily of Sand-Silt-Clay mixtures in varying amounts, including Lean Clay (CL), Lean Clay with Sand (CL), and Silty Sand (SM). With the exception of B-1, the sediment at this site was generally cohesive in nature and had an increasing gravel content with depth.

The sediment encountered throughout the sampling effort was typically minimally-to-slightly resistant towards Vibracore sampling.

4.1 SUMMARY OF PHYSICAL PARAMETER TESTING OF GEOTECHNICAL SAMPLE

The laboratory analysis indicates that the material encountered between 7.0 – 9.0 feet below the mudline is similar to the material encountered within the Vibracore samples (Sandy Lean Clay - CL). It should be noted that this material is believed to be native, and is directly below the “granular fill material” that underlies the riprap. The borings indicated that the material was medium dense, with a bpf value of 21.
