Dear Ed:

This progress report summarizes activities conducted on the Art Brass Plating project for the period July through September 2012. This work is being completed per the referenced Agreed Order between Art Brass Plating (Art Brass) and the Department of Ecology (Ecology).

Activities during Reporting Period Activities completed during the reporting period are summarized below.

Remedial Investigation The following RI activities were completed during this reporting period:

On September 27, 2012, Aspect submitted a revised draft of the Remedial Investigation report to Ecology.

The third quarter of groundwater monitoring was completed September 17 through 25, 2012. Results will be provided in the next progress report.

Art Brass coordinated in advance with PSC and Blaser Die Casting prior to making a round of water level measurements on August 10, 2012. Water level measurements collected by Art Brass are provided in Table 1 and monitoring well locations are shown on Figure 1. Groundwater elevation contour maps for the water table, shallow, and intermediate intervals are provided on Figures 2, 3, and 4, respectively.

EcoChem, Inc has validated data from the June groundwater sampling event. Validated results are presented in Table 2. Lab certificates and the EcoChem validation reports are provided in Appendix A.

Figures 5 through 8 depict groundwater concentrations of COCs. For monitoring well locations, the June 2012 value is presented in Figures 5 through 8. Previous results from prior groundwater grab samples as well as data from Blaser Die Casting and Capital Industries are also presented on the figures. Where multiple grab samples were collected within a given sampling interval, the highest reported value for that interval is depicted on the figure.

Interim Action Measures The following activities were completed during this reporting period:

The SVE system generally ran continuously during this reporting period. No significant adjustments were made to individual SVE flow rates.

The AS system has remained off since December 2011 as part of planned pulse testing and rebound assessment.

Quarterly groundwater monitoring in September at select near-facility locations to assess rebound potential and in accordance with the approved site-wide groundwater monitoring program.

On September 27, 2012, Aspect submitted a revised draft of the Interim Measure Evaluation to Ecology as an appendix to the Remedial Investigation report.

Performance monitoring of the SVE system was conducted in accordance with the Operation and Maintenance Plan, including:

Monthly monitoring of soil vapor extraction system operating parameters, including air flow rate, vacuum, and VOC/TCE concentrations at each SVE well, vapor sump, trench, and off-gas treatment system;

Monthly monitoring of pressure at soil vapor monitoring points using a micro-manometer;

Monitoring of TCE concentrations at soil vapor monitoring points exhibiting positive pressure, using low-level detector tubes;

Monthly air sampling for VOCs by EPA Method TO-15 laboratory analysis from the treatment system effluent; and

Quarterly air sampling for VOCs by EPA Method TO-15 laboratory analysis from the treatment system influent.

In accordance with the Operation and Maintenance Plan, this progress report includes interim performance monitoring data, comparison of the effectiveness of the interim measures with design goals, and recommendations to improve system effectiveness, where appropriate.

Interim Performance Monitoring Data – Performance monitoring data for April 2012 through September 2012 are discussed below. Monthly monitoring data are summarized in Tables 3 through 12 for the past year of operation to show trends in performance.

220 Findlay Vapor Mitigation System – The vapor mitigation system at 220 Findlay has operated continuously during the past six months. Vapor migration monitoring at sub-slab monitoring points has consistently demonstrated a negative pressure field extension below the building and no TCE has been detected below the slab.

SVE Operation – The SVE system generally operated continuously over the past six months with the exception of brief shut downs for periodic maintenance.


SVE Flow Rate and Vacuum – In general an increase in total flow and decrease in vacuum was observed from the end of the previous six month reporting period. During the summer months, lower water table elevation increases length of exposed SVE well screen and there is less condensation in SVE piping to restrict air flow. SVE flow rates and vacuums are summarized in Tables 3 and 4, respectively.

AS Operation, Flow Rate, and Pressure – The AS system was shut down at the beginning of December 2011 and has remained off as part of a planned pulse testing and rebound assessment. AS flow rates and pressures are summarized in Tables 5 and 6, respectively.

AS/SVE Balance – The ratio of SVE to AS flow rates has not been a concern because the AS system has remained off since December 2011. AS:SVE flow ratios are summarized in Table 7.

TCE Removal – TCE concentrations extracted by the SVE system have continued to decline without the AS system operating. Only two wells had detectable concentrations of TCE (SVE-3A and SVE-5A) at the end of September 2012. A total of 0.4 pounds have been removed in the past six months as compared to 2 pounds in the previous six month period. TCE concentrations at individual wells are summarized in Table 8. Overall mass removal is summarized in Table 9.

GAC Treatment Effectiveness – There has been no detection of TCE in the effluent vapor stream during the past six months. Effluent TCE concentrations, measured on a monthly basis using SUMMA canisters, are summarized in Table 9. Influent TCE concentrations, measured on a monthly basis using detector tubes and on a quarterly basis using SUMMA canisters, are also summarized in Table 9. Analytical results from influent and effluent samples collected using SUMMA canisters and analyzed for site-specific VOCs by method TO-15 are summarized in Table 10.

SVE Condensate – Based on field observations, condensate does not accumulate at a significant rate in the storage tank. Over the past six months, a negligible amount of condensate has been generated during manual draining of SVE lines using drain valves installed at low points in piping.

Vapor Migration Monitoring – A number of monitoring points have exhibited positive pressure in the past six months of operation. None of these points have had detectable TCE vapors and no corrective action has been taken since the AS system is already off. Vapor pressures and TCE concentrations from vapor migration monitoring are summarized in Tables 11 and 12, respectively.

Vapor Intrusion Groundwater monitoring results were evaluated with respect to VI considerations, in accordance with the requirements of the Groundwater Monitoring Plan. The completed


evaluation worksheets using results of the September monitoring round are attached as Appendix B.

Public Communications The project website was updated with an electronic copy of the previous progress report and the revised Remedial Investigation report. No other public communications were completed during this period.

Anticipated Work in the Upcoming Quarter Work anticipated to be performed during the next progress reporting period (October through December 2012) is summarized below.

Remedial Investigation The following RI activities are anticipated to be performed during the next reporting period:

Negotiate an interim Agreed Order with Ecology to continue monitoring and interim action activities pending negotiation of an Agreed Order for the planned Feasibility Study;

Submit proposed 2013 groundwater monitoring plan to Ecology; and

Complete quarterly groundwater monitoring in December 2012.

Interim Action Measures The following interim measure activities are anticipated to be performed during the next reporting period:

Groundwater monitoring results from April and June indicated a partial rebound in TCE concentrations near the Art Brass facility. The results from September groundwater monitoring will be evaluated to determine whether the trend will continue or level off.

If TCE concentrations continue to rebound, the AS system will remain off through quarterly groundwater sampling in December to further assess whether the trend continues or tapers off. If TCE concentrations show signs of leveling off, the AS system will be restarted as part of planned pulsed operations.

Quarterly groundwater sampling in December at select source area monitoring wells as part of ongoing pulse testing and in accordance with the approved site-wide groundwater monitoring program.

Performance monitoring of the AS/SVE system in accordance with the Operation and Maintenance Plan, including:

Monthly monitoring of soil vapor extraction system operating parameters, including air flow rate, vacuum, and VOC/TCE concentrations at each SVE well, vapor sump, trench, and off-gas treatment system;


Monthly monitoring of air sparging system operating parameters, including air flow rate and pressure, if the system is re-started as part of planned pulsed operations;

Monthly monitoring of pressure at soil vapor monitoring points using a micro-manometer;

Monitoring of TCE concentrations at soil vapor monitoring points exhibiting positive pressure, using low-level detector tubes;

Monthly air sampling for VOCs by EPA Method TO-15 laboratory analysis from the treatment system effluent; and

Quarterly air sampling for VOCs by EPA Method TO-15 laboratory analysis from the treatment system influent.

Vapor Intrusion December 2012 water table monitoring well sampling results will be evaluated with respect to VI considerations, in accordance with the requirements of the Groundwater Monitoring Plan.

Groundwater Monitoring The next groundwater monitoring event is scheduled for December 2012. The proposed 2013 groundwater monitoring plan will be submitted to Ecology.

Public Communications The project website will be updated with an electronic copy of this progress report. No other public communications are anticipated in the next quarter.

The next progress report, which will summarize activities completed from October through December, will be submitted on or before February 8, 2013. If you have any questions or comments regarding this report or the project, please call at your earliest convenience.

Notes1 Vertical datum is NAVD88

* Groundwater elevations calculated using Serfes method for a 72-hour tidal cycle

For the December 2008 groundwater monitoring event, the air sparging component of the remediation system was on. This has influenced some of the water levels in wells located within or near the facility.

Based on data available from surrounding water table wells, the water level measured at PZ-1 appears anomalous. The piezometer will be redeveloped and water levels will be reassessed during the May area-wide water level measurement event.

"NM" = Not measured

Notes1 Vertical datum is NAVD88

* Groundwater elevations calculated using Serfes method for a 72-hour tidal cycle (10/24-26/2010)

For the December 2008 groundwater monitoring event, the air sparging component of the remediation system was on. This has influenced some of the water levels in wells located within or near the facility.

Based on data available from surrounding water table wells, the water level measured at PZ-1 appears anomalous. The piezometer will be redeveloped and water levels will be reassessed during the May area-wide water level measurement event.

"NM" = Not measured

Notes:

(1) TCE concentrations measured using detector tubes, unless TO-15 analysis was available. Concentrations shown in italics were measured using TO-15 analysis.

(2) Total air discharge volume values are estimated using the vacuum recorded at the blower and the blower curve.

(3) Where detector tubes indicated non-detect results for influent TCE concentrations, half the detection limit was assumed (0.0625 ppm). Starting in January 2012, the previous TO-15 analysis result was assumed if it was lower than the detection limit of the detector tube.

Notes:

(2) Bold values indicate an increase in TCE concentration from baseline.

(3) Baseline measurements were taken before system startup.

(4) Shaded cells indicate monitoring not performed.

(5) water = water in tubing

(1) Sampling conducted with low-level TCE detector tubes (125 ppb detection limit). Where non-detect, sampling was conducted with 1-Liter SUMMA canisters on 8/14/2008 and analyzed for VOCs using TO-15. Sample purge rates were approximately 100 mL/min for VP monitoring points, and 3000 mL/min for MW monitoring points (1000 mL/min for MW-6).

PROJECT NARRATIVE

Basis for Data Validation

This report summarizes the results of compliance review (EPA Stage 2A) performed on groundwater, field quality control (QC), and laboratory QC data for Art Brass Plating quarterly monitoring. A complete list of samples is provided in the Sample Index.

Samples were analyzed by Analytical Resources, Inc. (ARI), Tukwila, Washington. The analytical methods and EcoChem project chemists are listed below.

Analysis Method Primary Review Secondary Review Volatile Organic Compounds SW 8260C

Total Metals SW 6010C SW 6020A

Dissolved Metals EPA 200.8 Mercury SW 7470A

Total Organic Carbon (TOC) SW 9060M Alkalinity, Bicarbonate, Carbonate, Hydroxide SM 2320

Chloride, Ortho-Phosphate, Sulfate EPA 300.0

Sulfide EPA 376.2 Total Cyanide SM4500-CN-E

Mary Sam Michela Powell-Hernandez

The data were reviewed using guidance and quality control criteria documented in the analytical methods; the Quality Assurance Project Plan (QAPP) for Art Brass Plating (Sept. 25, 2008); National Functional Guidelines for Organic Data Review (USEPA 1999), and National Functional Guidelines for Inorganic Data Review (USEPA 1994 & 2004).

EcoChem’s goal in assigning data validation qualifiers is to assist in proper data interpretation. If values are estimated (assigned a J), data may be used for site evaluation purposes; but reasons for data qualification should be taken into consideration when interpreting sample concentrations. Data that have been labeled as do-not-report (DNR) should not be used for any purpose. Values with no data qualifier meet all data measurement quality objectives and are acceptable for use.

Data qualifier definitions, reason codes, and validation criteria are included as Appendix A. A Qualified Data Summary Table is included in Appendix B. Data Validation Worksheets and communications will be kept on file at EcoChem, Inc. A qualified laboratory electronic data deliverable (EDD) is also submitted with this report.

Surrogates

The surrogate percent recovery (%R) control limits are 80-120%.

SDG UP03: The %R value for the surrogate compound toluene-d8 (156%) was greater than the upper control limit in the original analysis of Sample MW-17-60-040312. The recoveries for the other three surrogates were acceptable; therefore no action was taken.

SDG UP53: The %R value for the surrogate compound toluene-d8 (279%) was greater than the upper control limit in the original analysis of Sample MW-25-50-040512. The recoveries for the other three surrogates were acceptable; therefore no action was taken.

Matrix Spike/Matrix Spike Duplicates

SDGs UP54, UP73: Matrix spike/matrix spike duplicate (MS/MSD) analyses were not performed for these SDG. Precision and accuracy were evaluated using the laboratory control sample/laboratory control sample duplicate (LCS/LCSD) results.

Field Duplicates

The relative percent difference (RPD) control limit is 35% for results greater than five times the RL. For results less than five times the RL, the difference between the sample and duplicate must be less than the RL.

SDG UP03: One set of field duplicates were submitted: MW-8-30-040212 and MW-8-30-040212-D. All field precision criteria were met.

SDG UP53: Two sets of field duplicates were submitted: MW-15-040412 & MW-15-040412-D and MW-11-040412 & MW-11-040412-D. All field precision criteria were met.

Reported Results

SDG UP03: In the initial analyses of samples MW-1-040312, MW-17-60-040312, MW-16-40-040212, and MW-17-40-040312, the target analytes cis-1,2-dichloroethene and trichloroethene exceeded the linear range of the instrument. The results were flagged with an “E” by the laboratory. The samples were re-analyzed at dilution; both sets of data were reported. The results that exceeded the linear range were flagged as do-not-report (DNR-20). Results for all other analytes in the dilutions were flagged do-not-report (DNR-11).

SDG UP53: In the initial analyses of samples PMW-1-040412 and MW-25-50-040512, the target analytes cis-1,2-dichloroethene and trichloroethene exceeded the linear range of the instrument. The results were flagged with an “E” by the laboratory. The samples were re-analyzed at dilution; both sets of data were reported. The results that exceeded the linear range were flagged as do-not-report (DNR-20). Results for all other analytes in the dilutions were flagged do-not-report (DNR-11).



SDG UP54: In the initial analyses of Sample MW-26-55-040612, the target analyte trichloroethene exceeded the linear range of the instrument. In Sample MW-26-40-040612, the target analytes cis-1,2-dichloroethene and trichloroethene exceeded the linear range. The results were flagged with an “E” by the laboratory. The samples were re-analyzed at dilution; both sets of data were reported. The results that exceeded the linear range were flagged as do-not-report (DNR-20). Results for all other analytes in the dilutions were flagged do-not-report (DNR-11).

SDG UP73: In the initial analyses of Sample MW-22-30-040912, the target analyte cis-1,2-dichloroethene exceeded the linear range of the instrument. In Samples MW-20-60-041012 and MW-20-40-041012, the target analyte vinyl chloride exceeded the linear range. The results were flagged with an “E” by the laboratory. The samples were re-analyzed at dilution; both sets of data were reported. The results that exceeded the linear range were flagged as do-not-report (DNR-20). Results for all other analytes in the dilutions were flagged do-not-report (DNR-11).

IV. Overall Assessment

As was determined by this evaluation, the laboratory followed the specified analytical method. With the exceptions noted above, accuracy was acceptable as demonstrated by the LCS/LCSD MS/MSD, and surrogate recoveries and precision was acceptable as demonstrated by the LCS/LCSD, MS/MSD, and field duplicate RPD values.

Data were flagged as do-not-report (DNR) to indicate which result, from multiple reported analyses, should not be used.

Data flagged DNR should not be used for any purpose. All other data, as reported, are acceptable for use.

DATA VALIDATION QUALIFIER CODES Based on National Functional Guidelines

The following definitions provide brief explanations of the qualifiers assigned to results in the data review process.

U The analyte was analyzed for, but was not detected above the reported sample quantitation limit.

J The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample.

NJ The analysis indicates the presence of an analyte that has been “tentatively identified” and the associated numerical value represents the approximate concentration.

UJ The analyte was not detected above the reported sample quantitation limit. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample.

R The sample results are rejected due to serious deficiencies in the ability to analyze the sample and meet quality control criteria. The presence or absence of the analyte cannot be verified.

The following is an EcoChem qualifier that may also be assigned during the data review process:

DNR Do not report; a more appropriate result is reported from another analysis or dilution.

Inorganic Data

U Indicates that the target analyte was not detected at the reported concentration

*

B

N

NA

H

L

Duplicate RPD is not within established control limits

Reported value is less than the CRDL but ~ the Reporting Limit

Matrix Spike recovery not within established control limits

Not Applicable, analyte not spiked

The natural concentration of the spiked element is so much greater than the concentration spiked that an accurate determination of spike recovery is not possible

Analyte concentration is ::55 times the Reporting Limit and the replicate control limit defaults to ±1 RL instead of the normal 20% RPD

Organic Data


*

B

J

D

E

Q

Flagged value is not within established control limits

Analyte detected in an associated Method Blank at a concentration greater than one-half of ARI's Reporting Limit or 5% of the regulatory limit or 5% of the analyte concentration in the sample.

Estimated concentration when the value is less than ARI's established reporting limits

The spiked compound was not detected due to sample extract dilution

Estimated concentration calculated for an analyte response above the valid instrument calibration range. A dilution is required to obtain an accurate quantification of the analyte.

Indicates a detected analyte with an initial or continuing calibration that does not meet established acceptance criteria «20%RSD, <20%Drift or minimum RRF).

Indicates an analyte response that has saturated the detector. The calculated concentration is not valid; a dilution is required to obtain valid quantification of the analyte

The flagged analyte was not analyzed for

Spiked compound recovery is not reported due to chromatographic interference

The flagged analyte was not spiked into the sample

Estimated value for an analyte detected and confirmed by an analyst but with low spectral match parameters. This flag is used only for GC-MS analyses

The sample contains PCB congeners that do not match any standard Aroclor pattern. The PCBs are identified and quantified as the Aroclor whose pattern most closely matches that of the sample. The reported value is an estimate.

The analysis indicates the presence of an analyte for which there is presumptive evidence to make a "tentative identification"

The analyte is not detected at or above the reported concentration. The reporting limit is raised due to chromatographic interference. The Y flag is equivalent to the U flag with a raised reporting limit.

Estimated Maximum Possible Concentration (EMPC) defined in EPA Statement of Work DLM02.2 as a value "calculated for 2,3,7,8-substituted isomers for which the quantitation and lor confirmation ion(s) has signal to noise in excess of 2.5, but does not meet identification criteria" (Dioxin/Furan analysis only)

The analyte was positively identified on only one of two chromatographic columns. Chromatographic interference prevented a positive identification on the second column

The analyte was detected on both chromatographic columns but the quantified values differ by 2:40% RPD with no obvious chromatographic interference

Analyte signal includes interference from polychlorinated diphenyl ethers. (Dioxin/Furan analysis only)

Z Analyte signal includes interference from the sample matrix or perfluorokerosene ions. (Dioxin/Furan analysis only)

Geotechnical Data

A The total of all fines fractions. This flag is used to report total fines when only sieve analysis is requested and balances total grain size with sample weight.

F Samples were frozen prior to particle size determination

SM Sample matrix was not appropriate for the requested analysis. This normally refers to samples contaminated with an organic product that interferes with the sieving process and/or moisture content, porosity and saturation calculations

SS Sample did not contain the proportion of "fines" required to perform the pipette portion of the grain size analysis

W Weight of sample in some pipette aliquots was below the level required for accurate weighting

RE: Client Project: 050067, Art Brass Plating ARI Job: UY80

Dear Eric:

Please find enclosed the original chain of custody records and the final results for samples from the project referenced above. Analytical Resources, Inc. accepted four water samples and one trip blank in good condition on June 14, 2012. The samples were analyzed for VOAs and total and dissolved metals as requested.

A small amount of copper was detected in the method blank associated with the dissolved metals analyses of these samples. Copper was detected in both samples associated with this blank. Both samples were re-prepared and re-analyzed. The reanalyses proceeded without incident of note. The results for the re-analyses only have been submitted.

There were no further incidents of note associated with these analyses.

Copies of these reports and all raw data will be kept on file at ARI. If you have questions or require additional information, please feel free to contact me at your convenience.

Sincerely,

RE: Client Project: 050067, Art Brass Plating ARI Job: UZ33

Dear Dana:

JUL - 3 2012

Please find enclosed the final results for samples from the project referenced above. These samples were analyzed for total metals as requested on 06/19/12.

A matrix spike (MS) was prepared and analyzed in conjunction with sample SP-32-23-24. The percent recovery for nickel was slightly low following the analysis of the MS. Since the percent recovery for nickel was within acceptable QC limits for the corresponding LCS, it was concluded that the sample matrix was the cause of the low MS recovery. No corrective actions were taken.

A matrix duplicate (MD) was prepared and analyzed in conjunction with sample SP-32-23-24. The RPD for copper was high following the analysis of the MD. Since the percent recovery for copper was within acceptable QC limits for the corresponding LCS, it was concluded that a lack of sample homogeneity was the cause of the high RPD. No corrective actions were taken .

There were no further incidents of note associated with these analyses.

Copies of these reports and all raw data will be kept on file at ARI. If you have questions or require additional information, please feE?l free to contact me at your convenience.

Sincerely,


Y(0(~cvc Mark D. Hams Project Manager 206/695-6210 m a rkh@arilabs .com
