I. INTRODUCTION This Report of Findings presents the results of sampling and analysis of the sediment proposed to be dredged at the Schneider Dock and Intermodal Facility (SDI). A discussion of sampling activities and the sediment testing results is contained herein as well. Sediment sampling was performed at SDI’s dock August 23, 2013 by Pacific Affiliates (PA). All investigative activities were performed in general accordance with the Sediment Sampling and Analysis Plan (SAP) dated May 6, 2013 prepared by PA. The SAP was reviewed and approved by the Environmental Protection Agency (EPA), U.S. Army Corps of Engineers (USACE) and the Humboldt Bay Harbor, Recreation and Conservation District (HBHRCD) among other agencies.

A. Scope of Work Sediment sampling and analysis is part of a broader scope of work with the ultimate objective of obtaining permit coverage for maintenance dredging at the Schneider Dock. The scope of work includes the following activities:

Prepare SAP and obtain plan approval from all involved agencies Implement SAP Prepare Sediment Sampling and Analysis Report based upon results of sampling

activities Prepare CEQA document for maintenance dredging project Obtain dredging permits

B. Objectives The intent of sediment sampling and analysis is to characterize the sediment proposed to be dredged. Historical data from sediment testing previous completed has shown Humboldt Bay to have elevated concentrations of several chemicals. In order to properly handle and dispose of the dredged material, it must be characterized by thorough analysis.

C. Site Location Schneider Dock is located on the eastern shore of the North Bay Channel in Humboldt Bay, approximately ¼ of a mile west of Highway 101 at 990 West Waterfront Drive in Eureka, CA. Project parcels are described as APN’s 003-062-026, 003-062-024 and 003-062-021; the former being a tideland parcel owned by the City of Eureka and the latter two being the adjacent upland parcels owned by SDI. The subject properties are located along the southern boundary of Section 21, Township 5 North, Range 1 West. The proposed project will cause disturbance to waters of the United States within Humboldt Bay in the Eureka Plain Hydrologic Unit No. 110.



D. Background Schneider Dock, formerly the City of Eureka Dock A, has been used extensively for the import and export of cargo via Humboldt Bay throughout its history. In 1991, Mr. David Schneider purchased the upland parcel from Louisiana Pacific and assumed the lease of the tidelands, for which the dock is on, from the City of Eureka. SDI is used regularly by domestic and international vessels up to 700 feet in length with draft depths up to 35 feet. Cargo is stored on the upland parcels adjacent to the dock (APN’s 003-062-024, 003-062-028 and 003-062-021). SDI is seeking maintenance dredging permits from the USACE, California Regional Water Quality Control Board and HBHRCD. A permit exemption for dredging is being applied for through the California Coastal Commission (CCC). New legislation will go into effect on January 1, 2014 that does not require a lease through the State Lands Commission to dredge. An existing Coastal Development Permit (CDP-10-0003) is in the process of being amended to allow the temporary storage of various types of cargo, including dredged material, on Parcel 003-062-021. Schneider Dock was last dredged in 1974 to a depth of -37 feet Mean Lower Low Water (MLLW). The proposed maintenance dredging project is required to maintain adequate berthing depth for vessels that moor at the dock, as well as to insure the continued safe and convenient operation of the facility. It is proposed to remove a maximum of 2,000 cubic yards of sediment during the initial dredging event in an effort to reach the design dredge depth of -37 feet MLLW (plus two foot allowable overdredge to -39 ft MLLW). Dredging extents are described as follows: from the western edge of the dock to the eastern boundary of the Humboldt Bay channel (approximately 70 feet west from the north and south ends of the dock), and extending 100 feet northerly from the north end and 100 feet southerly from the south end of the dock (550 feet total length parallel with face of dock), for a total footprint of approximately 0.9 acres. Within this area, approximately 0.5 acres is proposed to be dredged to design depth, the remainder of the area is currently at or below -37 ft MLLW. All edges of the dredge area will be box cut which will allow the adjacent material to slough off to its natural angle of repose. Material that sloughs off into the dredge area will be removed during cleanup dredging (this is consistent with the methods used by the USACE during their dredging of the main channels in Humboldt Bay). Dredging procedures will consist of a crane with a clamshell bucket or a long reach excavator positioned either on a barge or on the dock. If a barge is used, dredge material will be pulled from the floor of the Bay and deposited into a containment area on the barge. Once the containment area is filled with sediment, it will be transferred to ten yard dump trucks positioned on the dock. If a barge is not used, dredged material will be placed directly into the dump trucks. The trucks will transport the sediment to a temporary retention basin in the graveled area of parcel 003-062-021. The temporary retention basin will consist of an area measuring approximately 96 feet by 116 feet that will be 80% enclosed with a 4 foot high earth berm. The remainder of the basin will be enclosed by a 1 foot high berm which will allow equipment access, but will contain any free



water. Dump trucks will unload the dredged material within the bermed area where it will remain for a minimum of two days to dry out. Once adequately dried, the material will be piled within the retention basin for storage until it is hauled offsite. The proposed site for the retention basin slopes gently away from the bay, thus any incidental surface run-off will not flow into the bay.

II. SAMPLING ACTIVITIES

A. Sample Collection Sediment sampling was performed by Pacific Affiliates staff from the company work barge on August 23, 2013. The barge was anchored at the sampling locations specified in the SAP. Samples were collected approximately 75 feet beyond the north and south ends of the dock and at the one-quarter and three-quarters points along the length of the dock. Actual sample locations are shown on the bathymetric map in Appendix II. Core samples were collected using a VibeCore-D coring device which utilizes three-inch diameter sample tubes. Prior to sampling, the sample tubes were decontaminated by washing the interior with a borax solution followed by a rinse with clean water, then a double rinse with distilled water. After securing a sample tube to the VibeCore, the assembly was lowered to the mudline, powered on and vibrated into the sediment. Using pre-measured markings on the rope, the distance the sample tube had advanced into the sediment was monitored. Once adequate depth was achieved, the sampler was hoisted out of the water and placed on the barge deck. Full depth samples were achieved at all locations. Based on conditions observed in the field, Sample A-1 achieved a depth of 8.5 feet below the mudline; A-2 reached 6.5 feet; A-3 reached seven feet; and A-4 reached 13 feet below the mudline. B. Sample Handling A plunger supplied with the sample tubes was used to push the sample out of the tube onto a sheet of plastic to be documented and cataloged. A fresh sample tube was used at each sample location. Logs of the core samples are provided in Appendix I. After separating the Z-layer portion of the sample (sediment from -39 ft to -39.5 ft MLLW) and discarding any sediment from below -39.5 ft MLLW, the sample was split along its longitudinal axis and homogenized. After homogenizing the samples, they were split into a primary subsample and a backup subsample. Each subsample consisted of two eight ounce jars and one four ounce jar, all of which were supplied by Enviromatrix, the laboratory performing the sediment analysis. Samples were labeled with the date, time, location, sample ID, client and the sampler. Primary subsamples were packed in a cooler with ice and shipped overnight to the laboratory along with proper chain-of-custody. Z-layer sediment was homogenized and placed in sample jars consistent with the primary and backup samples. Backup and Z-layer samples are stored in a refrigerator pending approval of the primary sample analysis.



III. LABORATORY ANALYSIS

A. Testing Laboratories Enviromatrix Analytical Inc. was contracted to perform the sediment analyses. Enviromatrix is an accredited environmental laboratory (ELAP No. 2564) in San Diego, CA. Enviromatrix subcontracted the following tests to laboratories listed below:

Grain size analysis - PTS Laboratories, Inc. Total Organic Carbon – Calscience Environmental Laboratories, Inc. Furans and Dioxins – Ceres Analytical Laboratories, Inc.

Appendix III contains a list of all chemicals tested for and the test methods utilized. All testing methods are in accordance with those approved by the EPA and are based on Table 6-1 of the Sediment Evaluation Framework (SEF). A discussion of deviations from the approved methods was held between Enviromatrix and EPA and approved with the condition that the lab describes their methods and detection limits in the results report, including any clean-up necessary to achieve the SEF limits as closely as possible. B. Sample Compositing Sediment samples from the four sample locations were shipped overnight to Enviromatrix. Per the SAP, laboratory personnel combined the four samples into a single 4:1 composite sample for analysis. Complete sediment testing results with laboratory quality control data and chain-of-custody documentation are contained in Appendix III.



IV. QUALITY CONTROL Pacific Affiliates received the analytic results for the sediment samples from Enviromatrix on September 12, 2013 and the grain size analysis on September 20, 2013. Enviromatrix, or the subcontracted laboratory, provided notes on all anomalies that occurred during testing which are summarized below. With the exception of the matrix spikes for Zinc, Nickel, Antimony and Total Sulfide and the duplicate for Di-n-butyl phthalate, all quality control (QC) results were within the limits. Due to noted non-homogeneity of the QC sample matrix, the Matrix Spike (MS) did not provide reliable results for accuracy and precision for Zinc and Nickel. The acceptable percent recovery range for the MS was 75-125% and the recovery for Zinc was 127%, and 133% for Nickel. Sample results for the QC batch were accepted based on Laboratory Control Sample (LCS) and Laboratory Control Sample Duplicates (LCSD) percent recoveries and Relative Percent Difference (RPD) values. The spike recoveries for Antimony and Total Sulfide were outside acceptance limits (75-125%) for the MS and Matrix Spike Duplicate (MSD) due to matrix interference. Recoveries for Total Sulfide were 126% for the MS and 130% for MSD. The LCS and LCSD were within acceptance limits showing that the laboratory is in control and the data is acceptable. The RPD result for Di-n-butyl phthalate was 117, which exceeded the QC limit of 30 due to non-homogeneity of the sample. Dilution of the Gasoline (C6-C10) sample was necessary due to nature of the matrix. All samples were handled with the appropriate chain-of-custody procedures and samples were analyzed within the required holding times. All laboratory QC batches were checked to ensure that the correct number of samples were analyzed, the holding times were not exceeded, surrogates recoveries were within stated control limits, and that Laboratory Method Blank, MS, MSD, LCS and LCSD were all tested and within the acceptable limits except as noted above and in the laboratory analytical reports.



V. DISCUSSION

A. Geology Sediment within the dredge prism was explored in four locations. The depth to the mudline, below zero feet MLLW, varied from approximately 27 feet on the north end of the dock to 33.5 feet in front of the southern half of the dock. Depths achieved during sampling ranged from approximately 6.5 feet to 13 feet below the mudline. Sampled depths below zero feet MLLW ranged from -39.5 feet to -40 feet. Sediments were found to be, on average, in the fine sand range with the gradation being 48% fine sands, 24% silt, 20% medium sand and 8% clay. All the sediments were dark gray in color. Logs of the core samples can be found in Appendix I.

B. Historical Data Extensive sediment sampling and analysis has been performed around Humboldt Bay as part of previous dredging projects. Analytic results from this project were compared to data from sediment testing performed at the Sierra Pacific Dock in 2006, which is located ±800 feet south of Schneider Dock, as well as from 11 City of Eureka waterfront mooring facilities and Woodley Island Marina, all of which were sampled in 2005. Though not all parameters tested for during this project were analyzed in the previous projects, several were. When comparing the recent test results to historical data, the concentrations detected at SDI in 2013 were within the ranges detected around the Bay and at the Sierra Pacific Dock in 2006.

C. Analytic Results The sediment sampling procedures used for this project were intended to provide data from a representative sample of the sediment to be dredged. Chemical concentrations were not delineated vertically or horizontally, as the individual core samples were composited into one single sample for analysis. Sediment quality guidelines for evaluating chemical analytical results consist of chemical screening levels (SLs), which are defined in the Sediment Evaluation Framework for the Pacific Northwest (SEF), Table 6-3. The SLs are designed to be protective of direct biological effects to benthic and aquatic organisms and correspond to a “no adverse effects level.” The following sections present the analytical results for the chemicals identified in Table 3 of the Sampling Plan. Shown in the following tables are the analytes and the respective detected concentration, Detection Limit (DL), Reporting Limit (RL) and, for certain chemicals, the SL and/or a note about the test result.



Conventionals As part of the characterization of the sediment, the following “conventional” tests were run to gain an understanding of the makeup of the sediment. The percentage of solids in the sample and a grain size analysis of the solids were used to determine the physical characteristics of the sediment. Both summarized in the following table. Table 1 - Physical characteristics of sediment ANALYSIS RESULT UNITSTotal Solids, as received 64.0 %Coarse sand 0 %Medium sand 19.91 %Fine sand 48.39 %Silt 24.16 %Clay 7.53 %Median Grain Size 0.177 mm

Also tested for were Total Organic Carbon (10,000 mg/kg), Total Sulfides (5.2 mg/kg) and Ammonia as N (4.4 mg/kg). Metals Detectable concentrations of Arsenic, Chromium, Copper, Mercury, Lead, Mercury, Nickel, and Zinc were found in the sediment sample. Compared with historical data from around Humboldt Bay, these are average concentrations. All detected concentrations were found to be below the Screening Levels (SLs) established in SEF Table 6-3.

Polycyclic Aromatic Hydrocarbons A number of PAH’s were detected in the sediment sample. The reported concentrations were well below the SLs and, in some cases, were below the RLs. Previous testing at the SPI dock indicated lower levels of PAH’s, however, the limit used in testing was 300 ug/L, which is much higher than the current limits.

Dioxins/Furans A number of dioxins and furans were detected in the sediment sample, however, the majority of the positive results were detected below the DL and were flagged as being an estimated concentration. OCDD were not flagged as being below the DL, however, they were detected below the SQLs, as were the other detected dioxins and furans. The concentration of 1,2,3,4,6,7,8-HpCDD was detected at 0.0216 μg/kg, which is above the SQL of 0.005 μg/kg. OCDD was flagged as being present in the method blank as well.

Using the Toxicity Equivalence Factors (TEF) published by the EPA (EPA 2010), the Toxicity Equivalence (TEQ) of the dioxins and furans were calculated as shown in Table 14 below. For the purpose of the evaluation, two TEQ values were calculated for those compounds which returned non-detect results. The first TEQ value assumes the test result was equal to zero; the second TEQ value assumes the test result was equal to one-half of the detection limit. Overall TEQs for the sediment ranged from 1.33 to 1.54 pg/g, depending on the assumed non-detect concentration. These values are relatively low and when compared to the TEQ results from the 11 City of Eureka waterfront sites tested in 2005, the values from Schneider Dock would be on the lower end of the ranges calculated, which were from 1.78 to 7.70 pg/g.

VI. CONCLUSIONS Though a number of chemicals were detected in the sediment sample, the concentrations of the detected chemicals were similar to background levels within Humboldt Bay. Provided the dredging is completed as approved by the governing agencies (work windows, equipment, dredging procedures, etc.), the project should not cause or contribute to degradation of groundwater or water quality in Humboldt Bay. Dredged sediment shall be handled appropriately and disposed of at an upland facility approved to accept the material as characterized.

Notes and Definitions

R-06 Sample dilution was necessary due to nature of the matrix.

QR-02 The RPD result exceeded the QC limits due to non-homogeneity of sample.

QM-06 Due to noted non-homogeneity of the QC sample matrix, the MS/MSD did not provide reliable results for accuracy and precision. Sample results for the QC batch were accepted based on LCS/LCSD percent recoveries and RPD values.

QM-05 The spike recovery was outside acceptance limits for the MS and/or MSD due to matrix interference. The LCS and/or LCSD were within acceptance limits showing that the laboratory is in control and the data is acceptable.

J Detected but below the Reporting Limit; therefore, result is an estimated concentration (CLP J-Flag).

Sample results reported on a dry weight basis (if indicated in units column)
