Sediment Sampling and Analysis Plan November 2012 Former Reynolds Metals Reduction Plant 1 110730-02.01

1 INTRODUCTION AND BACKGROUND INFORMATION

This Sediment Sampling and Analysis Plan (SSAP) is Appendix A to the Work Plan Addendum No. 3 (Anchor QEA 2012a) and describes the sediment collection, testing, and quality control (QC) procedures that will be used to characterize Columbia River sediment adjacent to the former Reynolds Metals Reduction Plant in Longview, Washington (Site; see Figure 1). The work described in this SSAP is being conducted as part of a Remedial Investigation and Feasibility Study (RI/FS), consistent with the requirements of the Agreed Order (AO) No. DE-8940, issued by the Washington State Department of Ecology (Ecology) to Northwest Alloys, Inc. (Northwest Alloys), a subsidiary of Alcoa, Inc., and Millennium Bulk Terminals –Longview, LLC (MBTL), in February 2012. The Draft RI/FS Report (Anchor QEA 2012b) presents a summary of the operational and sampling history at the Site, as well as a preliminary Conceptual Site Model that will be further developed as the Draft Final RI/FS is prepared. This SSAP was prepared consistent with current Ecology, Puget Sound Estuary Program (PSEP), and U.S. Environmental Protection Agency (USEPA) protocols for sampling and analysis (Ecology 2008; PSEP 1986, 1997a, 1997b, 1997c; USEPA 1993) and Test Methods for the Evaluation of Solid Waste: Physical/Chemical Methods, 3rd Edition (USEPA 1986). The contents and structure of this SSAP are consistent with guidance provided in Ecology’s Sediment Source Control Standards User Manual, Appendix B: Sediment Sampling and Analysis Plan Appendix (SAPA; Ecology 2008).

1.1 Current Site Uses

The Site is located at 4029 Industrial Way in Longview, Washington (see Figure 1). The facility covers approximately 416 acres, with approximately 100 acres of developed land. MBTL currently leases the Site from Northwest Alloys and operates a multi-product bulk terminal at the Site. The project area defined by this SSAP is located in the vicinity of the Columbia River shoreline at the southern edge of the Site and includes portions of shallow, submerged aquatic lands partially contained within the boundaries of Washington Department of Natural Resources (WDNR) Aquatics Lands Lease No. 20-B09222.

Introduction and Background Information


1.2 Historical Site Uses

The Site was originally developed in 1941 by Reynolds Metals Company (Reynolds) as an aluminum reduction plant, with aluminum smelting and casting operations. In 1967, operations expanded to include additional aluminum production capacity. In the late 1960s, Reynolds constructed a dock and mooring dolphins to facilitate the direct import of alumina ore to the plant via ocean-going vessels. Reynolds owned and operated the aluminum smelter continuously until 2001. Industrial uses continued after the 2001 closure of the aluminum smelter. Site operations transitioned to a multi-modal bulk materials handling facility by Chinook Ventures, Inc. (Chinook), which continued until 2011. Chinook operated the property as a private port for the import, handling, and export of dry bulk materials, such as alumina, coal, green petroleum coke (pet-coke), cement, fly ash, slag and other materials. MBTL purchased certain Chinook assets on January 11, 2011, and now operates a multi-modal bulk materials handling facility at the Site.

1.3 Site Stormwater and Wastewater

Wastewaters and stormwater from the Site are managed consistent with existing National Pollutant Discharge Elimination System (NPDES) Permit WA 000008-6. The NPDES permit includes extensive monitoring requirements. The two Site outfalls that discharge to the Columbia River include Outfall 001S and Outfall 002A (see Figure 2). Outfall 001S discharges treated effluent from the Sanitary Sewer Treatment Plant. Outfall 002A discharges treated process water and stormwater from the Wastewater Treatment Plant (Facility 71) and stormwater treatment facilities (Facility 73), respectively (see Figure 2). The Site has three additional outfalls (003, 005, and 006) included in the NPDES permit; these outfalls discharge stormwater runoff to the Longview Consolidated Diking Improvement District (CDID) system ditches adjacent to the property (see Figure 2). CDID Ditch No. 14, located along the western property boundary, discharges directly to the Columbia River via the CDID Reynolds Pump Station, as shown in Figure 2. The Reynolds Pump Station at the terminus of CDID Ditch No. 14 also draws water from CDID Ditch No. 10 (see Figure 2) and has inputs from the greater City of Longview, which uses the ditch as a sanitary sewage overflow (Ecology 1983). In addition, CDID Ditch No. 14 may receive runoff and groundwater inputs from various cleanup sites located adjacent to CDID ditches



throughout Longview, including the closed Mount Solo landfill immediately west of the property. Characterization of drainage pathway soils associated with these outfalls is discussed in the Work Plan Addendum No. 3.

1.4 Previous Investigations

Several previous investigations have been performed within the Columbia River located adjacent to the Site. To date this work has included sampling by Ecology, Anchor QEA, LLC (Anchor QEA), and Weyerhaeuser. Specifically, these studies include the following:

• A sediment investigation conducted by Chinook in the vicinity of the existing dock berthing areas (Anchor QEA 2010; DMMP 2010)

• A sediment characterization study in support of maintenance dredging at the docks and a turning basin adjacent to the Weyerhaeuser property (USACE 2010)

• A sediment characterization study in support of maintenance dredging at the barge slip and ship access channel adjacent to Weyerhaeuser (Integral 2008; USACE 2009)

• A sediment investigation conducted by Ecology as part of a Class II NPDES Inspection at outfall areas offshore of the Site (Ecology 1991)

• Wastewater and stormwater discharge testing at Site Outfalls 001S and 002A to support historical NPDES permit applications

None of the previous investigations identified the presence of impacted sediments. Additional testing has been requested by Ecology to supplement these available data. A summary of existing sediment data from previous testing is described in the following subsections and provided in table format in Attachment A.

1.4.1 Chinook Sediment Investigation

In 2010, Chinook conducted an investigation of surface and subsurface sediments in the vicinity of the existing dock and berthing areas (see Figure 3). As part of this investigation, seven surface and seven subsurface sediment samples were collected. Attachment A, Tables A-1 and A-2, present the sampling results. Surface sediment grabs were analyzed for conventional parameters, metals, and polycyclic aromatic hydrocarbons (PAHs; Anchor QEA 2010). Subsurface sediment samples were analyzed for conventional parameters, metals, PAHs, semivolatile organic compounds (SVOCs), polychlorinated biphenyl (PCB) Aroclors,



and pesticides (DMMP 2010; Anchor QEA 2010). No PCBs were detected in any of the samples tested. None of the surface or subsurface results exceeded Dredged Material Management Program (DMMP) screening levels.

1.4.2 Weyerhaeuser Dredged Material Characterization

In addition to the sampling data available for the river immediately adjacent to the Site, additional sampling data are available for the area just up-river. The adjacent property owner, Weyerhaeuser, conducted routine maintenance dredging in 2009 and 2010. In 2008 and 2009, sediment testing was performed within the dredging areas, including testing of underlying sediments in accordance with the DMMP anti-degradation guidelines. Surface grab samples and subsurface core samples were collected within each dredge unit. Subsurface sediment samples were tested for Northwest Sediment Evaluation Framework (SEF) freshwater parameters, including testing for PCB Aroclors and dioxin/furans. Attachment A, Tables A-3 and A-4, present the sampling results. No PCBs were detected in any of the samples analyzed (USACE 2009, 2010). No sample analysis results exceeded SEF freshwater or DMMP marine screening levels. Analysis of dioxins/furans was required for three samples from one of the dredge units due to the unit’s proximity to potential upland sources of dioxin (i.e., pulp and paper operations). The dioxin/furan toxic equivalency quotient concentrations were very low (fewer than 1.0 nanograms per kilogram [ng/kg] dry weight) for the three samples tested, indicating no impacts to Columbia River sediments (USACE 2009, 2010).

1.4.3 1990 Ecology Class II NPDES Investigation

In 1990, Ecology conducted sediment sampling offshore of the Site as part of a Class II NPDES Inspection (Ecology 1991). Outfall 002A (see Figure 3) was the primary discharge for treated industrial wastewater used in the plant and still serves as the main treated stormwater outfall for the Site. Sediment sample locations included three stations adjacent to Outfall 002A (see Figure 3). Chemical testing included fluoride, cyanide, volatile organic compounds (VOCs), PAHs, pesticides, and PCB Aroclors; these results are summarized in Attachment A (see Table A-5). PCBs were not detected in any of the test samples collected near the Site. Bioassay testing was also performed, and no bioassay impacts were noted.



1.4.4 Historical Priority Pollutant NPDES Data for Outfalls 001S and 002A

In 1995, 2000, 2009, and 2011, Site wastewater and stormwater discharging from Outfalls 001S and 002A was collected and tested for a comprehensive list of priority pollutants in support of NPDES permit applications. Chemical testing included Sediment Management Standard (SMS) metals, SVOCs, PCB Aroclors, VOCs, and pesticides; these results are summarized in Attachment A (see Table A-6). SVOCs, PCBs, and pesticides were not detected in any samples collected near the Site.

2 OBJECTIVES AND SAMPLING DESIGN

On June 28, 2012, Ecology issued comments (Ecology 2012) on the Draft RI/FS Report for the Site. In their comment letter, Ecology requested an evaluation of potential pathways by which Site contaminants of concern may have been transported to Columbia River sediments. Based on this evaluation, Ecology is requiring additional sampling to augment previous testing done by Ecology, Anchor QEA, and others to provide further verification that historical Site activity has not impacted Columbia River sediments. Consistent with this request, supplemental Columbia River sediment sampling is proposed at eight nearshore locations and five outfall area locations, as shown in Figure 2. Sediment will be collected from 0 to 10 centimeters (cm) at each sample location. Additional sediment will be collected from 0.5 to 1.0 foot (or depth of grab) and archived at the laboratory for contingency analysis. These data will augment existing data available from previous sampling efforts. Tables 1 and 2 provide the sampling design for the nearshore and outfall sampling locations, respectively. The eight proposed nearshore locations are located along the riverbank at the southern edge of the Site (see Figure 2). These samples will be used to verify that no impacts to river sediments have occurred from Site soils or groundwater. The proposed surface grab stations are located in areas offshore of fill materials and perched nearshore groundwater. The five offshore stations are located in the vicinity of Site NPDES Outfalls 001S and 002A and in the vicinity of the outfall by the Reynolds Pump Station operated by the Longview CDID (see Figure 2). Most of these outfall area locations are located in the WDNR lease area and will require an access agreement or use authorization. Depending on the time required to obtain access for sampling, the data collected for these locations will either be published in the Draft Final RI/FS or in a subsequent RI/FS Addendum. Columbia River sediment samples will be analyzed for the full list of SMS parameters, including total solids (TS), total organic carbon (TOC), SMS metals1, SVOCs, and dioxin-like PCB congeners. Archived samples will be selectively analyzed based on the testing results of 0- to 10-cm samples. Detailed sampling and analysis procedures for the collection and analysis of sediment samples are described in Sections 3 and 4.

1 SMS metals are arsenic, cadmium, chromium, copper, lead, mercury, silver, and zinc.


3 FIELD SAMPLING METHODS

This section addresses the sampling program requirements for sample collection and processing.

3.1 Horizontal Positioning and Vertical Control

Horizontal positioning will be determined by the onboard differential global positioning system (DGPS) based on target coordinates shown in Tables 1 and 2. The target coordinates for contingency subsurface samples will be co-located with surface grab stations. Measured station positions will be reported in Washington State Plane South coordinates (North American Datum of 1983 [NAD83]) to the nearest foot. The DGPS accuracy is fewer than 3 feet and generally less than 1 foot, depending on the satellite coverage and the number of data points collected. The vertical elevation of each sediment station will be measured using a lead line and converted to mean lower low water elevation. Tidal elevations will be determined after sample collection using the National Oceanic and Atmospheric Administration’s (NOAA’s) tide station (ID 9440422) located in Longview, Washington.

3.2 Sampling Equipment Decontamination Procedures

Sample containers, instruments, working surfaces, and other items that may come into contact with sediment sample material must meet high standards of cleanliness. All equipment and instruments used that are in direct contact with the sediment collected for analysis must be made of glass, stainless steel, high-density polyethylene (HDPE) or polytetrafluoroethylene (PTFE) and will be cleaned prior to each day’s use and between sampling or compositing events. Decontamination of all items will follow PSEP protocols. The decontamination procedure is as follows:

• Scrub until free of visible sediment and rinse with Site water • Pre-wash rinse with tap water • Wash with solution of tap water and Alconox soap (brush) • Rinse with tap water

Field Sampling Methods


• Rinse three times with distilled water • Cover (no contact) all decontaminated items with aluminum foil

3.3 Surface Sediment Sample Collection

Surface sediment samples will be collected at the 11 locations shown on Figure 2 using a Van Veen grab sampler. The following sections present the Van Veen grab sample collection and processing protocols. Analytical methods are described in Section 5.

3.3.1 Van Veen Surface Sediment Sample Collection

Surface sediment samples will be collected from the 0- to 10-cm biologically active zone at 11 locations in the Columbia River (see Figure 2). In addition, one archive sample from each station will be collected from the 0.5- to 1-foot (or depth of grab) interval. Surface sediment samples will be collected using either a hydraulic or gravity driven Van Veen grab sampling device with a 1-foot depth. Sampling locations will be approached at slow boat speeds with minimal wake to minimize disturbance of bottom sediments prior to sampling. The grab sampler, which will be weighted as necessary to help achieve the target penetration depth, will be lowered over the side of the boat using a winch and davit connected to a cable at an approximate speed of 0.3 feet per second. When the sampler reaches the mudline, the cable will be drawn taut, and DGPS coordinates will be recorded. The sampler will be retrieved aboard the vessel and evaluated for acceptance based on the following criteria:

• Overlying water is present and has low turbidity • Target penetration depth of 1 foot is greater than or equal to 75 percent recovery

(%R) based on field measurements (for example, using a ruler) • Sampler is not overfilled • Sediment surface is undisturbed • No signs of winnowing or leaking from sampling device



Grab samples not meeting these criteria will be rejected, and the sample collection steps will be repeated until the acceptance criteria are met. Deployments will be repeated within a 10-foot radius of the proposed sample location. If adequate penetration is not achieved after three attempts, less penetration will be accepted and noted in the field daily log (see Attachment B).

3.3.2 Sample Processing

The following protocols will be used to process accepted surface sediment samples:

• Siphon Water. Siphon off water overlying the mudline, taking care not to remove sediment.

• Photograph Grab. Take digital photographs of each grab with a label indicating project, sample location, and date.

• Sample Logging. Record the sample description on the grab sample log form, including, but not limited to, the following observations, as appropriate:

− Physical soil description in accordance with the Unified Soil Classification System (includes soil type, density/consistency, and color)

− Substantial product and sheens − Odor (e.g., hydrogen sulfide or petroleum) − Vegetation − Human-made debris − Biological activity (e.g., shells, tubes, bioturbation, or organisms) − Any other distinguishing characteristics or features

• Remove Debris. Materials in the sample more than 2 inches in diameter and debris will not be subsampled into sample containers.

• Homogenize Grab. Collect sediment samples from the 0- to 10-cm and 0.5- to 1-foot depth intervals from inside the Van Veen sampler, without touching the sidewalls, using a decontaminated stainless steel trowel or equivalent. Place the sediment into a single decontaminated stainless steel bowl or HDPE bucket and homogenize until uniform color and texture is achieved.

• Fill Sample Containers. Using a decontaminated stainless steel spoon, fill pre-labeled, decontaminated sample containers for analytical testing.



Samples will then be packed on ice and transferred via laboratory courier to analytical testing laboratory (Apex Laboratories, LLC [Apex], in Tigard, Oregon) following the handling and chain-of-custody (COC) protocols described in Section 4.

3.4 Sample Identification

Tables 1 and 2 present detailed summaries of the sediment sampling design including sample nomenclature. The sample nomenclature is described in the following paragraph and bullet list. Each sediment sample will be assigned a unique alphanumeric identifier according to the following methods:

• Each nearshore area station ID will be identified by Anchor QEA (AQ)-Sediment (SE)-Sample Number 01 through 08 (e.g., AQ-SE-01).

• Each outfall area station ID will be identified by Anchor QEA (AQ)- Surface Sediment (SS)-Sample Number 03, 04, 09, 10, or 14 (e.g., AQ-SS-03).

• In addition, all archive sample intervals (collected from 0.5 to 1 foot below mudline) will have “-A” after the sample number (e.g, AQ-SE-01-A represents the archive (0.5 to 1 foot) sediment sample collected from nearshore area station AQ-SE-01; AQ-SS-03-A represents the archive sediment sample collected from outfall area station 03).

• A field duplicate collected from a sample will be identified by the addition of 50 to the sample number (e.g., AQ-SE-51 represents a field duplicate of station AQ-SE-01).

• For rinsate blank samples, “RB” will be added in front of the sample number. The resulting nomenclature of a rinsate blank of the decontaminated sample processing equipment after sample collection at station AQ-SE-01 would be AQ-SE-RB01.

3.4.1 Sample Containers and Labels

Sample containers and preservatives will be provided by the laboratory. The laboratory will maintain documentation certifying the cleanliness of bottles and the purity of preservatives provided. Specific container requirements are included in Table 3.



Each sample will have an adhesive plastic or waterproof paper label affixed to the container and will be labeled at the time of collection. The following information will be recorded on the container label at the time of collection:

• Project name • Sample identification • Date and time of sample collection • Preservative type (if applicable) • Analysis to be performed

3.5 Field Documentation

Documentation will consist of a daily log and sample collection forms (see Attachment B). All field notes will be made using an indelible ink pen. Corrections will be made by drawing a single line through the error, writing in the correct information, then dating and initialing the change. The daily logs are intended to provide sufficient data and observations to enable readers to reconstruct events that occurred during the sampling period. At a minimum, the following information will be included in this log:

• Names of field coordinator (FC) and person(s) collecting and logging the sample • Health and safety discussions • The sample station number • Date and collection time of each sediment sample • Observations made during sample collection, including weather conditions,

complications, vessel traffic, and other details associated with the sampling effort • Qualitative notation of apparent resistance of sediment column to sampling, including

notes on debris • Any deviations from the approved sampling plan

In addition to maintaining a daily log, sample collection forms will be completed for each sample. The sample collection forms will include standards entries for station identifier, station coordinates, date and time of sample location, type of samples collected, type of analyses for each sample, and specific information pertaining to the matrix being collected. In addition, the collection form will include information regarding penetration of the



sampler and physical characteristics of the sediment such as texture, color, odor, stratification, and sheens.

3.6 Field-Generated Waste Disposal

All sediment remaining after sampling will be washed overboard at the collection site prior to moving to the next sampling station. Any sediment spilled on the deck of the sampling vessel will be washed into the surface waters at the collection site. Sediment remaining following grab sample processing will be returned to the sampling location. All disposable sampling materials and personnel protective equipment used in sample processing, such as disposable coveralls, gloves, and paper towels, will be placed in heavy duty garbage bags or other appropriate containers. Disposable supplies will be placed in a normal refuse container for disposal as solid waste.


4 SAMPLE HANDLING AND CUSTODY

The section addresses the sampling program requirements for maintaining custody of the samples throughout the sample collection and shipping process and provides specific procedures for sample storage and shipping.

4.1 Sample Custody Procedures

Samples are considered to be in one’s custody if they are: 1) in the custodian’s possession or view; 2) in a secured location (under lock) with restricted access; or 3) in a container that is secured with an official seal, so the sample cannot be reached without breaking the seal or seals. COC procedures will be followed for all samples throughout the collection, handling, and analysis process. The principal document used to track possession and transfer of samples is the COC form. Each sample will be represented on a COC form the day it is collected. All data entries will be made using an indelible ink pen. Corrections will be made by drawing a single line through the error, writing in the correct information, then dating and initialing the change. Blank lines/spaces on the COC form will be lined-out and dated and initialed by the individual maintaining custody. A COC form will accompany each container of samples to the analytical laboratory. Each person who has custody of the samples will sign the COC form and ensure that the samples are not left unattended unless properly secured. Copies of all COC forms will be retained in the project files.

4.2 Sample Storage, Transport, Delivery, and Receipt Requirements

Samples will be stored and preserved in accordance with the associated analytical method requirements. Holding time, sample container, and preservation requirements are specified in Table 3. All samples will be transported to the analytical laboratory by an Apex courier. Specific sample packing procedures are as follows:

Sample Handling and Custody


• Coolant ice will be sealed in separate double plastic bags and placed in the coolers. • Individual sample containers will be placed in a sealable plastic bag, packed to

prevent breakage, and transported in a sealed cooler. • Glass jars will be separated in the cooler by shock absorbent material (e.g., bubble

wrap) to prevent breakage. • The coolers will be clearly labeled with sufficient information (name of project, time

and date container was sealed, person sealing the container, and the consultant’s office name and address) to enable positive identification.

Upon transfer of sample possession to the analytical laboratory courier, the persons transferring custody of the sample container will sign the COC form. Upon receipt of samples at the laboratory, the receiver will record the condition of the samples on a sample receipt form. COC forms will be used internally in the laboratory to track sample handling and final disposition.


5 ANALYTICAL METHODS

This section summarizes the analytical methods for all surface sediment samples. All sample analyses will be conducted in accordance with Ecology-recommended methods (Ecology 2008). Prior to analysis, all samples will be maintained according to the appropriate holding times and temperatures for each analysis (see Table 3). Table 4 presents the proposed analytes, the analytical methods to be used, and the laboratory reporting limits (RLs) for the evaluation of sediment samples. Chemical/physical testing will be conducted at Apex, an Ecology-accredited laboratory, located in Portland, Oregon. All chemical and physical testing will be conducted using SAPA (Ecology 2008) and PSEP protocols and will adhere to SW-846 quality assurance (QA)/QC procedures and analysis protocols (USEPA 1986) where appropriate. In completing chemical analyses for this project, the contract laboratories are expected to meet the following minimum requirements:

• Adhere to the methods outlined in this SSAP, including methods referenced for each analytical procedure.

• Deliver PDF and electronic data, as specified. • Meet reporting requirements for deliverables. • Meet turnaround times for deliverables. • Implement QA/QC procedures, including data quality objectives (DQOs) discussed in

Section 6 and Table 5, laboratory QC requirements (see Table 6), and performance evaluation testing requirements.

• Notify the project QA/QC manager of any Quality Assurance Project Plan (QAPP) QA/QC problems when they are identified to allow for quick resolution.

• Allow laboratory and data audits to be performed, if deemed necessary.


6 QUALITY ASSURANCE/QUALITY CONTROL

This section describes DQOs and field and laboratory QA/QC requirements. Also included are the equipment calibration and maintenance requirements and the assessment of compliance and response actions.

6.1 Data Quality Objectives and Criteria

The DQO for this project is to ensure that the data collected are of known and acceptable quality for project objectives described in Section 2 to be achieved. The quality of laboratory data is assessed by precision, accuracy, representativeness, comparability, and completeness (the "PARCC" parameters). Definitions of these parameters and the applicable QC procedures are presented in the following subsections. Applicable quantitative goals for these data quality parameters are listed or referenced in Table 5.

6.1.1 Precision

Precision is the ability of an analytical method or instrument to reproduce its own measurement. It is a measure of the variability, or random error, in sampling, sample handling, and laboratory analysis. ASTM International (ASTM) recognizes two levels of precision: 1) repeatability—the random error associated with measurements made by a single test operator on identical aliquots of test material in a given laboratory, with the same apparatus, under constant operating conditions; and 2) reproducibility—the random error associated with measurements made by different test operators, in different laboratories, using the same method but different equipment to analyze identical samples of test material (ASTM 2002). In the laboratory, "within-batch" precision is measured using replicate sample or QC analyses and is expressed as the relative percent difference (RPD) between the measurements. The "batch-to-batch" precision is determined from the variance observed in the analysis of standard solutions or laboratory control samples from multiple analytical batches. Field precision will be evaluated by the collection of blind field duplicates for chemistry samples at a frequency of 1 in 20 samples. Field chemistry duplicate precision will be

screened against an RPD of 50 percent for sediment samples. However, no data will be qualified based solely on field homogenization duplicate precision. Precision measurements can be affected by the nearness of a chemical concentration to the method detection limit (MDL), where the percent error (expressed as RPD) increases. The equation used to express precision is as follows:

( )

( )/2CC100%CC

Where: RPD = relative percent difference C1 = larger of the two observed values C2 = smaller of the two observed values

6.1.2 Accuracy

Accuracy is a measure of the closeness of an individual measurement (or an average of multiple measurements) to the true or expected value. Accuracy is determined by calculating the mean value of results from ongoing analyses of laboratory-fortified blanks, standard reference materials (SRMs), and standard solutions. In addition, laboratory-fortified (i.e., matrix-spiked) samples are also measured, which indicates the accuracy or bias in the actual sample matrix. Accuracy is expressed as %R of the measured value, relative to the true or expected value. If a measurement process produces results for which the mean is not the true or expected value, the process is said to be biased. Bias is the systematic error either inherent in a method of analysis (e.g., extraction efficiencies) or caused by an artifact of the measurement system (e.g., contamination). Analytical laboratories use several QC measures to eliminate analytical bias, including systematic analysis of method blanks, laboratory control samples, and independent calibration verification standards. Because bias can be positive or negative, and because several types of bias can occur simultaneously, only the net (or total) bias can be evaluated in a measurement. Laboratory accuracy will be evaluated against quantitative matrix spike (MS) and surrogate spike recovery performance criteria provided by the laboratory. Accuracy can be expressed



as a percentage of the true or reference value or as a %R in those analyses where reference materials are not available and spiked samples are analyzed. The equation used to express accuracy is as follows:

%R = 100% x (S-U)/Csa

Where: %R = percent recovery S = measured concentration in the spiked aliquot U = measured concentration in the unspiked aliquot Csa = actual concentration of spike added

Field accuracy will be controlled by adherence to sample collection procedures outlined in Section 3.

6.1.3 Bias

Bias is the systematic or persistent distortion of a measurement process that causes errors in one direction. Bias assessments for environmental measurements are made using personnel, equipment, and spiking materials or reference materials as independent as possible from those used in the calibration of the measurement system. When possible, bias assessments should be based on analysis of spiked samples, rather than reference materials, so the effect of the matrix on recovery is incorporated into the assessment. A documented spiking protocol and consistency in following that protocol are important to obtaining meaningful data quality estimates.

6.1.4 Representativeness

Representativeness expresses the degree to which data accurately and precisely represent an environmental condition. For the Site, the list of analytes has been identified to provide a targeted assessment of the potential contaminants in nearshore and outfall area sediments in the Columbia River.



6.1.5 Comparability

Comparability expresses the confidence with which one dataset can be evaluated in relation to another data set. For this program, comparability of data will be established through the use of standard analytical methodologies, reporting formats, and common traceable calibration and reference materials.

6.1.6 Completeness

Completeness is a measure of the amount of data that is determined to be valid in proportion to the amount of data collected. Completeness will be calculated as follows:

C = (Number of acceptable data points) x 100 (Total number of data points)

The DQO for completeness for all components of this project is 95 percent. Data that have been qualified as estimated because the QC criteria were not met will be considered valid for the purpose of assessing completeness. Data that have been qualified as rejected will not be considered valid for the purpose of assessing completeness.

6.1.7 Sensitivity

Analytical sensitivities will comply with the recommended practical quantitation limits (PQLs) provided in SAPA (Ecology 2008). The MDL is defined as the minimum concentration at which a given target analyte can be measured and reported with 99 percent confidence that the analyte concentration is greater than zero. Laboratory PQLs or RLs are defined as the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions. Laboratory RLs will be used to evaluate the method sensitivity and/or applicability prior to the acceptance of a method for this program. The sample-specific RLs will be reported by the laboratory and will take into account any factors relating to the sample analysis that might decrease or increase the RL (e.g., dilution factor, percent moisture, sample volume, and sparge volume). In the event that the RLs are



elevated for a sample due to matrix interferences and subsequent dilution or reduction in the sample aliquot, the data will be evaluated by Anchor QEA and the laboratory to determine if an alternative course of action is required or possible. If this situation cannot be resolved readily (i.e., detection limits less than criteria are achieved), Ecology will be contacted to discuss an acceptable resolution.

6.2 Field Quality Assurance and Quality Control

Field activities must be conducted in such a manner that results meet specified quality objectives and are fully defensible. Guidance for QA/QC is derived from the protocols developed for the PSEP (1986, 1997a, 1997b, 1997c), USEPA Test Methods (1986, 2008a), National Functional Guidelines (USEPA 1999, 2004, 2008b), and the cited methods. Samples will be uniquely identified with a sample identification number that, at a minimum, specifies sample matrix, sample number, sample location, and type of sample. Specific sample identification nomenclature is provided in Section 3.4.

6.2.1 Field Quality Assurance Sampling

Field QA procedures will consist of the following acceptable practices for collecting and handling samples. Adherence to these procedures will be complemented by periodic and routine equipment inspection. Field QA samples will be collected along with environmental samples. Field QA samples are useful in identifying possible problems resulting from sample collection or sample processing in the field. The collection of field QA samples will include equipment rinsate blanks and field duplicates. Field QA samples will be collected at a frequency of 1 in 20 samples processed, as specified in Table 6. All field QA samples will be documented in the field daily log and verified by the QA/QC manager or designee.

6.2.2 Rinsate Blanks

Rinsate blank samples will be collected to evaluate the efficiency of field decontamination procedures. One equipment rinsate blank will be collected at a frequency of 1 per 20 samples processed during sediment sampling.



Deionized water for the equipment rinsate blank will be provided by the laboratory. The equipment rinsate blank consists of pouring deionized water over the sampling equipment after sample collection and decontamination and collecting the rinsate water into sample jars. The rinsate blank will be prepared by placing laboratory-supplied deionized water directly into sampling containers prior to sample collection.

6.2.3 Field Duplicates

One field duplicate sample will be collected and analyzed for every 20 sediment samples processed in the field. The field duplicate sample consists of collecting additional sediment from one location, processing that sample consistent with procedures outlined in this SSAP, and then submitting a blind split of that sample to the laboratory.

6.2.4 Additional Sediment Volume for Laboratory QA/QC

Field QA samples will also include the collection of enough sample volume to ensure that the laboratory has sufficient amounts to run the program-required analytical QA/QC (MS/matrix spike duplicate [MSD]) samples for analysis, as specified in Table 6. For sediment samples, an extra 8-ounce jar will be collected to run MS/MSD. The samples designated for MS/MSD analyses should be clearly marked on the COC.

6.3 Laboratory Quality Assurance and Quality Control

Laboratory QC procedures, where applicable, include initial and continuing instrument calibrations, laboratory control samples, matrix replicates, MSs, surrogate spikes (for organic analyses), and method blanks. Table 6 lists the frequency of analysis for laboratory QA/QC samples, and Table 5 summarizes the DQOs for precision, accuracy, and completeness. Results of the QC samples from each sample group will be reviewed by the analyst immediately after a sample group has been analyzed. The QC sample results will then be evaluated to determine if control limits have been exceeded. If control limits are exceeded in the sample group, the QA/QC manager will be contacted immediately, and corrective action (e.g., method modifications, followed by reprocessing the affected samples) will be initiated prior to processing a subsequent group of samples.



6.3.1 Laboratory Instrument Calibration and Frequency

An initial calibration will be performed on each laboratory instrument to be used at the start of the project, after each major interruption to the analytical instrument, and when any ongoing calibration does not meet method control criteria. A calibration verification will be analyzed following each initial calibration and will meet method criteria prior to analysis of samples. Continuing calibrations will be performed daily prior to any sample analysis to track instrument performance. The frequency of continuing calibration will be in accordance with Table 6. If the ongoing continuing calibration is out of control, the analysis must come to a halt until the source of the control failure is eliminated or reduced to meet control specifications. All project samples analyzed while instrument calibration was out of control will be reanalyzed.

6.3.2 Laboratory Duplicates/Replicates

Analytical duplicates provide information on the precision of the analysis and are useful in assessing potential sample heterogeneity and matrix effects. Analytical duplicates and replicates are subsamples of the original sample that are prepared and analyzed as a separate sample.

6.3.3 Matrix Spikes and Matrix Spike Duplicates

Analysis of MS samples provides information on the extraction efficiency of the method on the sample matrix. By performing duplicate MS analyses, information on the precision of the method is also provided for organic analyses.

6.3.4 Method Blanks

Method blanks are analyzed to assess possible laboratory contamination at all stages of sample preparation and analysis. The method blank for all analyses must contain less than the RL of any single target analyte/compound. If a laboratory method blank exceeds this criterion for any analyte/compound, analyses must stop, the source of contamination must be eliminated or reduced, and the affected samples must be reanalyzed.



6.3.5 Laboratory Control Samples

Laboratory control samples are analyzed to assess possible laboratory bias at all stages of sample preparation and analysis. The laboratory control sample is a matrix-dependent spiked sample prepared at the time of sample extraction along with the preparation of sample and MSs. The laboratory control sample will provide information on the precision of the analytical process and, when analyzed in duplicate, will provide accuracy information, as well.

6.3.6 Laboratory Deliverables

Data packages will be checked for completeness immediately upon receipt from the laboratory to ensure that data and QA/QC information requested are present. QC sample frequencies will be compared to the criteria in Table 6.

6.4 Instrument/Equipment Testing, Inspection, and Maintenance Requirements

The following sections describe procedures for testing, inspection, and maintenance of field and laboratory equipment.

6.4.1 Field Instruments/Equipment

Field QC procedures will consist of the following standard instrument operation procedures and using consistent, acceptable practices for collecting measurements. Adherence to these procedures will be complemented by periodic and routine equipment inspection and calibration.

6.4.2 Field Instrument/Equipment Calibration

The subcontractor responsible for navigation will confirm proper operation of the navigation equipment daily. This verification may consist of internal diagnostics or visiting a location with known coordinates to confirm the coordinates indicated by the navigation system. No other field equipment requires testing or calibration. The winch line and sampling equipment will be inspected daily for fraying, misalignment of jaws, loose connections, and



any other applicable mechanical problems. Any problems will be noted in the field daily log and corrected prior to continuing sampling operations.

6.4.3 Laboratory Instruments/Equipment

In accordance with the QA program, the laboratory shall maintain an inventory of instruments and equipment, and the frequency of maintenance will be based on the manufacturer’s recommendations and/or previous experience with the equipment. The laboratory preventative maintenance program, as detailed in their QA Plan, is organized to maintain proper instrument and equipment performance and to prevent instrument and equipment failure during use. The program considers instrumentation, equipment, and parts that are subject to wear, deterioration, or other changes in operational characteristics; the availability of spare parts; and the frequency at which maintenance is required. Any equipment that has been overloaded, mishandled, gives suspect results, or has been determined to be defective will be taken out of service, tagged with the discrepancy noted, and stored in a designated area until the equipment has been repaired. After repair, the equipment will be tested to ensure that it is in proper operational condition. Anchor QEA will be promptly notified in writing if defective equipment casts doubt on the validity of analytical data. Anchor QEA will also be notified immediately regarding any delays due to instrument malfunctions that could impact holding times. The analytical laboratory will be responsible for the preparation, documentation, and implementation of the preventative maintenance program. All maintenance records will be checked according to the schedule on an annual basis and recorded by the responsible individual. The laboratory QA/QC manager, or designee, shall be responsible for verifying compliance.

6.4.4 Laboratory Instrument/Equipment Calibration

Proper calibration of equipment and instrumentation is an integral part of the process that provides quality data. Instrumentation and equipment used to generate data must be calibrated at a frequency that ensures sufficient and consistent accuracy and reproducibility. As part of their QC program, laboratories perform two types of calibrations. A periodic



calibration is performed at prescribed intervals (i.e., balances, drying ovens, refrigerators, and thermometers), and operational calibrations are performed daily, at a specified frequency, or prior to analysis (i.e., initial calibrations) according to method requirements. Calibration procedures and frequency are discussed in the laboratory’s QA Plan. Calibrations are discussed in the laboratory standard operating procedures (SOPs) for analyses. The laboratory QA/QC manager will be responsible for ensuring that laboratory instrumentation is calibrated in accordance with specifications. Implementation of the calibration program shall be the responsibility of the respective laboratory Group Supervisors. Recognized procedures (USEPA, ASTM, or manufacturer’s instructions) shall be used when available. Physical standards (i.e., weights or certified thermometers) shall be traceable to nationally recognized standards, such as the National Institute of Standards and Technology (NIST). Chemical reference standards shall be NIST SRMs or vendor-certified materials traceable to these standards. The calibration requirements for each method and respective corrective actions shall be accessible, either in the laboratory SOPs or the laboratory’s QA Plan, for each instrument or analytical method in use. All calibrations shall be preserved on electronic media.

6.5 Inspection/Acceptance Requirements for Supplies and Consumables

Inspection and acceptance of field supplies, including laboratory-prepared sampling bottles, will be performed by the FC. All primary chemical standards and standard solutions used in this project, either in the field or laboratory, will be traceable to documented, reliable, commercial sources. Standards will be validated to determine their accuracy by comparison with an independent standard. Any impurities found in the standard will be documented.

6.6 Assessments and Response Actions

Once data are received from the laboratory, a number of QC procedures will be followed to provide an accurate evaluation of data quality. Specific procedures will be followed to assess



data precision, accuracy, and completeness. Section 7.3.2 provides the data validation and verification procedures.

6.6.1 Response and Corrective Actions

The following paragraphs identify the responsibilities of key project team members and actions to be taken in the event of an error, problem, or nonconformance to protocols identified in this document.

Field Activities The FC will be responsible for correcting equipment malfunctions during the field sampling effort. The project QA/QC manager will be responsible for resolving situations identified by the FC that may result in noncompliance with this SSAP. All corrective measures will be immediately documented in the field daily log.

Laboratory The laboratory is required to comply with their SOPs. The laboratory project manager (PM) will be responsible for ensuring that appropriate corrective actions are initiated, as required for conformance with this SSAP. All laboratory personnel will be responsible for reporting problems that may compromise data quality.


7 DOCUMENTATION, RECORD KEEPING, AND REPORTING REQUIREMENTS

This section describes laboratory and field documentation and record keeping, data validation, and data reporting requirements.

7.1 Documentation and Records

This project will require central project files to be maintained at Anchor QEA. Project records will be stored and maintained in a secure manner. Each project team member is responsible for filing all necessary project information or providing it to the person responsible for the filing system. Individual team members may maintain files for individual tasks but must provide such files to the central project files upon completion of each task. A project-specific index of file contents is to be kept with the project files. Hard copy documents, when necessary, will be kept on file at Anchor QEA throughout the duration of the project, and all electronic data will be maintained in the database at Anchor QEA.

7.1.1 Field Logs

Field team members will keep a daily record of significant events, observations, and measurements in a field log. All field activities will be recorded in a daily field log maintained by the FC or designee in accordance with the procedures provided in Section 3.5. The field logs will be stored in the project files upon completion of the sampling event.

7.1.2 Analytical and Chemistry Records

Analytical data records will be retained by the laboratory and in the Anchor QEA central project files. For all analyses, the data reporting requirements will include those items necessary to complete data validation, including electronic copies of all raw data. The analytical laboratory will be required, where applicable, to report the following:

• Project Narrative. This summary, in the form of a cover letter, will discuss problems, if any, encountered during any aspect of analysis. This summary should discuss, but is not be limited to, QC, sample delivery, sample storage, and analytical difficulties. Any problems encountered, actual or perceived, and their resolutions will be documented in as much detail as appropriate.

Documentation, Record Keeping, and Reporting Requirements


• COC Records. Legible copies of the COC forms will be provided as part of the data package. This documentation will include the time of receipt and condition of each sample received by the laboratory. Additional internal tracking of sample custody by the laboratory will also be documented on a sample receipt form. The form must include all sample cooler temperatures measured at the time of sample receipt.

• Sample Results. The data package will summarize the results for each sample analyzed. The summary will include the following information when applicable:

− Field sample identification code and the corresponding laboratory identification code

− Sample matrix − Date of sample extraction − Date and time of analysis − Weight and/or volume used for analysis − Final dilution volumes or concentration factor for the sample − Identification of the instrument used for analysis − MDLs − Method RLs accounting for sample-specific factors (e.g., dilution or TS) − Analytical results with reporting units identified − Data qualifiers and their definitions

• QA/QC Summaries. This package will contain the results of the laboratory QA/QC procedures. Each QA/QC sample analysis will be documented with the same information required for the sample results. No recovery or blank corrections will be made by the laboratory. The required summaries are listed as follows (additional information may be requested):

− Calibration Data Summary. This summary will report the concentrations of the initial calibration and daily calibration standards and the date and time of analysis. The response factor, percent relative standard deviation, percent difference, and retention time for each analyte will be listed, as appropriate. Results for standards to indicate instrument sensitivity will be documented.

− Relative Retention Time. A report of the relative retention time of each analyte detected in the samples for both primary and conformational analyses will be included.

− Original Data. Legible copies of the original data generated by the laboratory will include the following: o Sample extraction, preparation, identification of extraction method used, and

cleanup logs o Instrument specifications and analysis logs for all instruments used on days of

calibration and analysis o Reconstructed ion chromatograms for all samples, standards, blanks,

calibrations, spikes, replicates, and reference materials o Enhanced spectra of detected compounds with associated best-match spectra

for each sample o Printouts of full-scan chromatograms and quantitation reports for each

instrument used, including reports for all samples, standards, blanks, calibrations, spikes, replicates, and reference materials

o Original data quantification reports for each sample o Original data for blanks and samples not reported



All instrument data shall be fully restorable at the laboratory from electronic backup. Laboratories will be required to maintain all records relevant to project analyses for a minimum of 7 years.

7.1.3 Data Reduction

Data reduction is the process by which original data (analytical measurements) are converted or reduced to a specified format or unit to facilitate analysis of the data. Data reduction requires that all aspects of sample preparation that could affect the test result, such as sample volume analyzed or dilutions required, be taken into account in the final result. It is the laboratory analyst’s responsibility to reduce the data, which are subjected to further review by the laboratory PM, the PM, the QA/QC manager, and independent reviewers. Data reduction may be performed manually or electronically. If performed electronically, all software used must be demonstrated to be true and free from unacceptable error.

7.2 Data Management

Field data sheets will be checked for completeness and accuracy by the FC prior to delivery to the data manager. All data generated in the field will be documented on hard copy and provided to the office data manager, who is responsible for the data’s entry into the database. All manually entered data will be checked by a second party. Field documentation will be filed in the main project file after data entry and checking are complete. Laboratory data will be provided to the data manager in PDF and EQuIS electronic formats. The laboratory data that are provided electronically and loaded into the database will undergo a 10-percent check against the laboratory data report. Data will be validated or reviewed manually, and qualifiers, if assigned, will be entered manually. The accuracy of all manually entered data will be verified by a second party. Data tables and reports will be exported from EQuIS to MS Excel tables, and data will be exported in the Environmental Information Management (EIM) format to provide to Ecology.

7.3 Data Validation and Usability

The following sections describe the procedures that will be used to review project data quality.



7.3.1 Data Review, Validation, and Verification

All data will undergo a Level 3 (USEPA Stage 2B) validation. During the validation process, analytical data will be evaluated for method and laboratory QC compliance, and their validity and applicability for program purposes will be determined. Based on the findings of the validation process, data validation qualifiers may be assigned. The validated project data, including qualifiers, will be entered into the project database, thus enabling this information to be retained or retrieved, as needed.

7.3.2 Validation and Verification Methods

Data validation includes signed entries by the field and laboratory technicians on field data sheets and laboratory data sheets, respectively; review for completeness and accuracy by the FC and laboratory PM; review by the data manager for outliers and omissions; and the use of QC criteria to accept or reject specific data. All data will be entered into the EQuIS database, and a raw data file will be generated. Ten-percent verification of the database raw data file and 100-percent verification of validation qualifiers applied will be performed by a second data manager or designee. Any errors in the raw data file will be corrected, and the database will be established. All laboratory data will be reviewed and verified to determine whether all DQOs have been met and that appropriate corrective actions have been taken, when necessary. The project QA/QC manager or designee will be responsible for the final review of all data generated from analyses of samples. The first level of review will take place in the laboratory as the data are generated. The laboratory department manager or designee will be responsible for ensuring that the data generated meet minimum QA/QC requirements and that instruments were operating under acceptable conditions during generation of data. Data packages will be checked for completeness immediately upon receipt from the laboratory to ensure that data and QA/QC information requested are present. DQOs will be assessed by a reviewer using current National Functional Guidelines data validation requirements (USEPA 1999, 2004) by considering the following:



• Holding times • Initial calibrations • Continuing calibrations • Method blanks • Surrogate recoveries • Detection limits • RLs • Laboratory control samples • MS/MSD samples

Data will be validated in accordance with the project-specific DQOs previously described, analytical method criteria, and the laboratory’s internal performance standards based on their SOPs.

7.4 Reconciliation with User Requirements

The QA/QC manager will review data after each survey to determine if DQOs have been met. If data do not meet the project’s specifications, the QA/QC manager will review the errors and determine if the problem is due to calibration/maintenance, sampling techniques, or other factors and will suggest corrective action. It is expected that any problem would be able to be corrected by retraining, revision of techniques, or replacement of supplies/equipment; if not, the DQOs will be reviewed for feasibility. If specific DQOs are not achievable, the QA/QC manager will recommend appropriate modifications. If matrix interference is suspected to have attributed to the exceedance, adequate laboratory documentation must be presented to demonstrate that instrument performance or laboratory technique did not bias the result. In cases where the DQOs have been exceeded and corrective actions did not resolve the outlier, data will be qualified per USEPA National Functional Guidelines (USEPA 1999, 2004, and 2008b). In these instances, the usability of the data will be determined by the extent of the exceedance. Rejected data will be assigned an “R” qualifier and will not be used for any purposes.



7.5 Data Report

A Draft Final RI/FS Report will be prepared and submitted to Ecology for review and approval. The RI/FS Report will document the results of the sediment sampling and analysis program, as well as upland investigations outlined in the Work Plan Addendum No. 3 (Anchor QEA 2012a). The RI/FS Report, at a minimum, will contain the following information:

• A statement of the purpose of the investigation will be included. • A summary of the field sampling, field data, and laboratory analytical procedures

(reference will be made to the final SSAP) will be included. Deviations, whether intended or unintended, will be documented. Failure to meet sampling objectives or DQOs of sufficient magnitude that lead to rejection of results will be well documented, as necessary.

• A general vicinity map showing the location of the Site with respect to familiar landmarks and a sampling station map will be included. Coordinates will be reported in an accompanying table for all stations. All geographical coordinates submitted to Ecology for inclusion in the EIM database will be in the NAD83, State Plane, Washington South Zone.

• Chemical analysis results data tables summarizing chemical and conventional variables, as well as all pertinent QA/QC data, will be included.

• An interpretation of the results against the appropriate regulatory criteria will be included. Any additional data gaps (and necessary sampling and analysis activities necessary to fill these data gaps) will be discussed.

• Copies of complete laboratory data packages, including signed COC forms, as appendices or attachments, will be included.

• Copies of applicable sections of the field log, as appendices or attachments, will be included.

• Copies of data validation reports and/or findings, as appendices or attachments, will be included.



7.6 Ecology EIM Submittal

Electronic data for the sediment investigation will be submitted to Ecology’s EIM System per Ecology’s Policy 840. Final validated data will be submitted, along with the data report, and will comply with Sub-appendix E of the SAPA (Ecology 2008).
