SAMPLING AND ANALYSIS PLAN HAWAII KAI MARINA MAINTENANCE DREDGING

HAWAII KAI, OAHU, HAWAII

1.0 Introduction

This Sampling and Analysis Plan (SAP) details activities to be undertaken for characterization ofsediment removed during maintenance dredging work at Hawaii Kai Marina, in Hawaii Kai, Oahu,Hawaii. The design dredge depth for this project is (-) 6 feet Mean Lower Low Water (MLLW). TheHawaii Kai Marina Community Association is responsible for the operation and maintenance of themarina.

The project site is situated in the eastern portion of the island of Oahu, Hawaii in Hawaii Kai.Maintenance dredging of approximately 43,000 cubic yards of material from the marina will restorethe design depths for safe navigation. The attached figure shows the locations where maintenancedredging is required. The dredged material stockpile site is located near the Yacht Club(intersection of Hawaii Kai Drive and Kalanianaole Highway).

In order to use of the dredged material as beneficial reuse fill material at a 20 acre farm in Wainae,it will be necessary to characterize the dredged material by sampling and to provide acharacterization verifying that there are no environmental concerns with respect to using thematerial on the farm.

In-situ sampling was conducted on the sediments that have accumulated. The samples wereanalyzed for Liquid Limit, Moisture (Walter) Content, Plastic Unit, Plasticity Index, Specific Gravity,Total Organic Carbon, Total Solids, Total Solids (preserved), Total Volatile Solids, Ammonia,Sulfide, Atterberg Classification, pH, Grain Size, Total Metals (Arsenic, Barium, Cadmium,Chromium, Copper, Lead, Mercury, Nickel, Selenium, Silver and Zinc), Organometallic Compounds(Butyline, Dibutyltin and Tributyltin), Aromatic Hydrocarbons, Semi-Volitile Organic Compounds,Polychlorinated Biphenyls (Arochlors 1016, 1221, 1232, 1242, 1248, 1254 and 1260), Pesticides,DRO, Motor Oil and Oil/Grease. Only Total Nickel, Dibenzo(a,h)anthracene and Heavy Oil wereencountered at concentrations exceeding the HEER Office Tier I Environmental Action Levels(EALs). Total Nickel and Dibenzo(a,h)anthracene exceeded the EALs in only one (1) out of four(4) samples, with the average of all four samples being below the EALs. Heavy Oil exceeded theEALs in three (3) out of four (4) samples, with the average of all four samples being slightly abovethe EALs. This indicates that the primary contaminant of potential concern for the sediment isHeavy Oil (Residual Range Organics (RRO)). With a dredge depth of 6 feet, it is anticipated thatthe overall dredge material may be below the EAL for RRO.

To assure completeness of the analytical suite, five (5) initial samples will be analyzed for ResidualRange Organics (RRO), Polyaromatic Hydrocarbons (PAHs), RCRA 8 Total Metals,Organochlorine Pesticides and PCBs. Once all of the initial five samples are complete, theanalytical results will be reviewed to determine if any of the contaminates have a reasonablepotential of exceeding it’s HEER Office Tier I Environmental Action Levels (EALs). Subsequentsamples will be analyzed for RRO, Total Nickel and Dibenzo(a,h)anthracene; as well as anycontaminate having a reasonable potential of exceeding it’s EAL determined by the initial fivesamples.

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 2

In order to verify that the concentrations in the dredge spoils will be appropriate for use as fillmaterial, it is proposed to conduct multi-incremental sampling of the stockpiled sediments on theorder of one multi-incremental sampling per each 1,200 to 1,500 cubic yards of dredge materials.Stock

This SAP provides information on the background of the site, extent and intensity of contamination(if known), rationale for the investigation, sampling methodologies and data quality controlprocedures and objectives.

2.0 Data Acquisition Objectives

The data from this sampling effort is to be used to verify that the dredge spoils will be suitable foruse as fill material for a 20 acre farm in Wainae, i.e., the MIS concentrations of the analytes ofconcern in the material will be acceptable for unrestricted use if under the HEER Office Tier IEnvironmental Action Levels (EALs). To assure completeness of the analytical suite, five (5) initialsamples will be analyzed for Residual Range Organics (RRO), Polyaromatic Hydrocarbons (PAHs),RCRA 8 Total Metals, Organochlorine Pesticides and PCBs. Once all of the initial five samplesare complete, the analytical results will be reviewed to determine if any of the contaminates havea reasonable potential of exceeding it’s EAL. Subsequent samples will be analyzed for RRO, TotalNickel and Dibenzo(a,h)anthracene; as well as any contaminate having a reasonable potential ofexceeding it’s EAL determined by the initial five samples.

Since the anticipated volume of dredge spoils for this project is 43,000 cubic yards, it has beenelected to use a volume of approximately 1,200 to 1,500 cubic yards for each DU.

3.0 Construction Methodology

Based on information provided by the dredging contractor, American Marine Corporation, Inc.(AMC), the marina will be dredged using the mechanical method.

The maintenance dredging will be performed by barge mounted equipment. Either an excavatorwith an extended arm or crane with a clam shell bucket would be used. The sediment would beremoved by a closed bucket and deposited into a water tight bin on the barge or dump scow. Oncefull, the barge or the dump scow would be towed to shore. The sediment will be unloaded from thebarge directly into the dewatering basin. Berms will be constructed around the stockpile site tocontain the sediment and water within the site. No sediment or water will be allowed to dischargeinto the ocean. The sediment will be allowed to dry sufficiently before it is sampled and hauled bytruck to an approved upland placement site.

The barge carrying the excavator or crane, and dump scow (if used) will be moored in place bytemporary anchors within the marina and steel spuds mounted on each corner of the barge. Thesteel spuds are lowered and raised by a hydraulic motor. Once deployed into the harbor bottomthey help to stabilize the barge. Lighted buoys will be used to mark the anchors and/or anchorchains.

4.0 General Sampling Procedures

As a professional consulting organization, EKNA seeks to provide the highest quality of work. Toaid in establishing a reasonable standard of care in work, EKNA uses standards promulgated bythe American Society of Testing and Materials (ASTM) and the Hawaii Department of Health,Hazard Evaluation and Emergency Response Office (HDOH HEER) as guidance in developingprocedures for field work. The following standards are incorporated into this Plan by reference.

C ASTM D 2488-93 Description and Identification of Soils (Visual-Manual Procedure)EKNA personnel that will be involved in the field sampling work are familiar with descriptionof soils by the Unified Soil Classification System (USCS). This standard has beenincorporated to provide guidance for field procedures that may be used to develop USCSdescriptions of soil in lieu of the rigorous physical laboratory testing required in the USCS(ASTM D 2487).

C ASTM D 4840-88 Sampling Chain of Custody ProceduresChain of Custody procedures are considered to be an industry standard. This standard hasbeen incorporated to provide guidance for procedures that may be used under this project.

C ASTM D 5088-90 Decontamination of Field Equipment Used at Nonradioactive WasteSites

C HDOH HEER Guidance for the Evaluation of Imported and Exported Fill Material,Including Contaminant Characterization of Stockpiles dated October2011

C HDOH HEER Technical Guidance Manual for the Implementation of the Hawai'iState Contingency Plan (TGM) Interim Final - November 12, 2009

Decontamination procedures are considered to be an industry standard. This standard has beenincorporated to provide guidance for procedures that may be used under this project. Standardprocedures for decontamination are discussed in a subsequent section of this plan.

4.1 Sampling Strategy and Stockpile Management

At present, it is anticipated 30 primary samples and three (3) triplicate QA/QC samples fromthree DUs will be obtained.

Each DU will be stockpiled individually with a volume of approximately 1,200 to 1,500 cubicyards and labeled by the individual sample number for that DU. Each DU stockpile will bemaintained individually until analytical results clear the DU for reuse at the farm. StockpiledDUs that exceed any EAL will be transported and disposed of at a State regulated land fill.

DUs will be multi-incrementally sampled (MIS) to develop a set of individual analyses foreach DU in accordance with HDOH HEER guidelines listed above for bulk, MI soil sampling.Because of the limited area designated for stockpiling, it is estimated that 5 sampling eventswill be conducted.

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 4

4.2 Soil Sampling Methodology

During MI sampling, each stockpiled DU will be flattened to a thickness of three feet or lessfor a stratified random approach of MIS collection. As an alternative to flattening eachstockpile, heavy equipment such as a backhoe or excavator may be used to access theinterior area of the stockpile for complete MIS. Incremental samples will be collected usinga slide hammer driven lined sampler, similar hand coring device or hand tools. At least 40to 50, 30-50 gram “increments” will be collected from each DU volume of dredged materialand combined for preparation of a bulk, multi-increment sample for that DU. The bulk MIsample (i.e., combined increments for a single DU) will be placed in a 1-2 gallon, heavyduty, ziplock bag. Each bulk MIS will be labeled and then placed in a suitable cooler fortransportation. Coolers will be lined with plastic to minimize the potential of contamination.Samples will be submitted to TestAmerica Laboratories, Inc. laboratory and/or AdvancedAnalytical Lab LLC. The analytical laboratory will follow HDOH HEER TGM guidance forprocessing of bulk, MI soil samples (i.e. ensure heterogeneity by drying the sample, sieveit and then subsampled for analysis. Subsampling is carried out by the collection of 30-50small masses of soil to prepare an aliquot of appropriate mass for testing - minimum tengrams, including for metals).

4.3 Sample Handling

All samples will be collected, stored and transported in general accordance with U.S.Environmental Protection Agency (EPA) procedures.

Completed sample labels will be affixed to the samples and the samples sealed in anotherplastic bag to minimize the potential of cross contamination and contamination of samplemanagement equipment. The labels will be secured to the sample container in a mannerthat will minimize the potential of loss of the label.

Samples will be collected under a strict Chain of Custody (COC) protocol. Samplecollection will be in accordance with the following protocol:

C Samples will be collected using pre-cleaned equipment (scoop, sampler, liner, etc.).

C Collected samples will be logged onto COC forms providing the followinginformation:

- date of sample location,- time of sample collection,- test method for analyses; and,- sampler’s name.

C Each sample shall be labeled with a unique sample number and other informationrequired on the label.

C A strict Chain of Custody (COC) will be maintained for all samples.

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 5

C After collection, all samples will be preserved as appropriate to the sample matrixand target analyte. Samples will be kept cool and stored over wet ice or icesubstitute (in bags sealed to prevent leakage) in coolers for transport to the fixedlaboratories for analyses.

C All samples will be submitted to the local laboratory representative within 48 hoursof collection for shipment to the laboratory by the representative.

4.4 Contamination Control

Contamination control procedures will be implemented to maintain sample integrity andreduce the potential of contamination of the samples from external sources or cross-contamination between sampling locations. Field equipment is considered to be divided intotwo (2) categories - single use disposable equipment and reusable equipment. Disposableequipment includes the following items:

C Single use sampling equipment.C Plastic bags.C Nitrile outer gloves.C Miscellaneous supplies such as paper towels and plastic sheeting for general

cleanup of the sample management work area.

Disposable equipment shall be used only at one sampling location and only for a singlesampling event. Gloves shall be changed after handling of each sample.

Reusable equipment may be further divided into two (2) subcategories - sample contactingand non-sample contacting. Sample contacting equipment generally includes the handcoring device, sampling tubes, scoops and incidental equipment such as knives for cuttingsamples.

Sample contacting equipment will be cleaned by washing and scrubbing in a solution ofLiquidnox™ or Alconox™ and water followed by two (2) tap water rinses. The detergentwash and tap water rinses will be in plastic buckets. Detergent wash and rinse water willbe changed at each boring location. The sample contacting equipment will be allowed toair dry.

To minimize potential of cross-contamination during sample handling, field personnel thathandle samples will change out gloves between samples. Gloves and other PPE will becontained, managed disposed of as solid waste.

To further minimize cross-contamination and to minimize potential contamination of sampletransport containers, the containers will be lined with plastic.

4.5 Analytical Methods

The samples will be analyzed in a fixed laboratory as indicated in Table 1.

5.0 Quality Assurance Plan

5.1 Quality Control Procedures

Field Quality Assurance and Quality Control (QA/QC) procedures will be used to assure therepresentativeness of the sampling. The QC procedures are designed to determine theeffects, if any, of sample collecting, containing, storing, and shipping on sample integrity.Three (3) triplicate samples from three (3) of the Decision Unit volumes of sediment will becollected for QA/QC data.

5.1.1 Field Duplicate

Field Duplicates provide information about sample variability, and serve as a QCcheck on the adequacy of the sample collection and handling with respect toestimating the average value of the contaminants in the field.

For this project, a duplicate sampling will be collected and analyzed on threeselected DUs. All sets of incremental samples will be submitted to the laboratoryfor the same analyses as listed in Sections 4.1 and 4.5 of this plan.

The duplicate samples will be assigned unique blind sample numbers. Codes using“QC” or “DUP” SHALL NOT be used for the duplicates.

5.1.2 Field Replicate

Field Replicates are intended to provide information about sample variability, andserve as a QA check on the precision of the analytical procedures.

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 7

For this project, a single replicate sampling will be collected and analyzed on threeselected DUs. All sets of incremental samples will be submitted to the laboratoryfor the same analyses as listed in Sections 4.1 and 4.5 of this plan.

The replicate samples will be assigned unique blind sample numbers. Codes using“QA” or “REP” SHALL NOT be used for replicates.

5.2 Data Review

Chemical data from the dredged material will be developed from the analyses of thesamples. All chemical data will be reviewed to determine that QA/QC objectives have beenmet and that the data is representative.

5.2.1 Holding Times

When a sample is collected and removed from its natural environment, chemicalconditions within the sample matrix begin to change, or degrade. All target analytesand analytical methods have been assigned holding times which are considered tobe the maximum length of time, after sample collection, that a sample may be heldand still be considered to be representative of the chemical conditions in the matrixsampled at the location sampled and at the time sampled.

Initial data review for all chemical data on EKNA projects includes a check to verifythat the samples were analyzed within the holding time allotted to the target analyteand method.

Sample analyses which do not conform to holding times will be flagged. If it isdetermined that the samples and data are sufficiently degraded, the samples anddata may be considered to be invalid and subject to corrective action. Correctiveaction on samples will be the responsibility of EKNA and the subcontractorlaboratory.

5.2.2 Data Assessment

Precision is a measure of mutual agreement among individual measurements of thesame property, usually under prescribed similar conditions. Precision can beexpressed in terms of the relative percent difference (RPD), relative standarddeviation (RSD) and/or standard deviation. Analytical precision is measured byreplicate analyses of individual samples. To compare two replicates, RPD will beused.

Where: RPD = the relative percent differenceC1 = the larger of the two observed valuesC2 = the smaller of the two observed values

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 8

To compare between more than two replicates, RSD is used:

Where: RSD = the relative standard deviationS = the standard deviationY = the mean of replicate values

Generally, an RPD of about 35% or less will be considered to be valid.

Completeness is a measure of the amount of valid data obtained from ameasurement system compared to the amount that was expected to be obtainedunder normal conditions and is defined as follows:

Where: %C = the percent completenessV = the number of measurements judged validn = the total number of measurements necessary to

achieve a specified statistical level of confidence indecision making

In general, the completeness should be about 85 percent or more.

5.2.3 Laboratory Quality Control Procedures

Laboratory services for this project will be provided by TestAmerica Laboratories,Inc. and/or Advanced Analytical Lab LLC. in Honolulu, Hawaii. The analyticallaboratory will follow HDOH HEER TGM guidance for processing of bulk, MI soilsamples.

The laboratories are independent, internationally accredited analytical laboratory(ILAC Accredited ISO/IEC 17025: 2005 analytical facility). As accreditedlaboratories, they are familiar with quality control procedures. The following is ageneral discussion of typical internal laboratory quality control procedures.

Internal Quality Control for Industrial hygiene sample analysis requires the followinganalysis:

QC Sample Type Frequency Acceptance LimitsInitial Calibration Blank (ICB) Beginning of each set <10% of regulatory limitIndependent Calibration Verification (ICV) Each analytical batch + / - 10% of known valueContinuing Calibration Verification (CCV) 1 per 10 samples + / - 10% Continuing Calibration Blank (CCB) One per CCV <10% of regulatory limitMatrix Spikes (MS) 1:1 unknown sple w/ std 3 1 per 20 samples (+/- 25% of known value)Matrix Spikes Duplicate (DUP) 1 per 20 samples (+/- 25% RPD)

QC Sample Type Frequency Acceptance Limits

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 9

Duplicate Sample (DUP) 1 per 20 samples (+/- 25% RPD)Matrix Blank (MB) or Reagent Blank (RB) Each analytical batch <10% of regulatory limitCalibration Curve Linearity Each analytical batch R2 => 0.97 units

The analysis of QC samples for organics, metals, and general chemistrydemonstrate that adequate recoveries have been obtained in spiked (fortified)samples, check for matrix interference in samples, confirm that reagents used foranalyses have no impurities that interfere with the analysis of the analyte, identifyif cross-contamination between samples has occurred during work up, checklaboratory performance against reference materials, and verify the precision andaccuracy of methods. The results from the QC samples such as matrix spike (MS)and matrix spike duplicate (MSD) are compiled and graphed on control charts. Theprimary function of the control charts are to define control limits for the individualmethods.

Method blanks are used to determine if any contamination or additive amounts ofanalyte are being introduced into the sample. The blanks prepared need to containless than the detection limit for all analytes. If the concentration of the associatedblanks is above the detection limit and if the analyte concentration is 5 to 10 percentof the action level, re-analysis of the sample must occur. If the re-analysis is notdone, the data is reported and flagged as an estimated value. The blank is neversubtracted from the sample.

Matrix Spike/Matrix Spike Duplicate determine accuracy and precision by calculatingthe amount recovered and the relative percent difference.

In addition to the standard laboratory QA/QC procedures, for this project, thelaboratory will run a single set of internal triplicate analyses for this project. The DUselected for triplicate analyses will be designated on the Chain of Custody when thesamples are submitted. The selected DU will not be the same as those selected forduplicate or replicate sampling. Laboratory procedures for processing the fieldsample include adequate mixing of the bulk sample (by ‘tumbling’ the plastic samplebag by hand), emptying and spreading the sample on a flat surface and selecting30 scoops (approximately 10 gms each) to obtain the laboratory sample (0.25g willbe collected from this 300g MIS sample). Each of the replicates is selected in thismanner from the same bulk sample to obtain the triplicate sample for laboratoryanalysis. The sample for analysis is selected from this material and processed asrequired for the method of choice.

5.2.4 Corrective Actions

Corrective actions are initiated whenever the data quality indicators, e.g., holdingtimes, laboratory control samples, blanks, spikes, etc., suggest that data quality maybe suspect. Corrective actions begin with identification of the problem. Potentialsources of problems include non-conformance to methods and procedures,improper data reduction, equipment malfunctions, or contamination from externalsources.

Sampling and Analysis Plan (SAP) C.N. 2728-00F#Hawaii Kai Marina Maintenance Dredging Revised June 14, 2013Hawaii Kai, Oahu, Hawaii Page 10

Identification of problems and initiation of corrective actions is the responsibility ofthe project manager and the laboratory QA/QC manager. Initial corrective actionsmay include re-examination of the analytical data or retesting of the sample to aidin identification of the problem. Corrective action may also include re-sampling andtesting of the new sample.

Further corrective actions may include retraining of staff to assure conformance toprocedures and standards, equipment repair, more frequent equipmentmaintenance/ calibration and isolation/removal of sources of external contamination.
