1 Introduction

On behalf of Daimler Trucks North America LLC (DTNA), the Bridgewater Group, Inc.

(Bridgewater) is submitting this Addendum summarizing the results of October 2014

stormwater sampling and analysis at the Western Star Truck Manufacturing Plant (TMP)

facility in Portland, Oregon (see Figures 1 and 2). The sampling was conducted as required

by the 2002 Voluntary Cleanup Agreement between Freightliner LLC and the DEQ

(Agreement No. LQVC-NWR-02-02, effective December 2, 2002) and by a June 27, 2014,

letter from the DEQ (DEQ, 2014), and performed in a manner consistent with the 2010

Oregon Department of Environmental Quality’s (DEQ) Guidance for Evaluating the

Stormwater Pathway at Cleanup Sites (Stormwater Guidance). The approach and methods

for the sampling were presented in an April 2006 Stormwater Evaluation Work Plan (Work

Plan) and July 2006 revisions (Maul Foster & Alongi, Inc. [MFA], 2006 a and b), and the

DEQ’s June 15, 2006 and September 25, 2006 comments on the Work Plan and revisions

(DEQ 2006 a and b). In addition, this report includes the results of an October 2014 post-

cleanout video camera survey and sampling of solids in the stormwater line between the

Fathom Outfall and City of Portland (City) manhole AAJ831, as well as a video camera survey

to assess the potential accumulation of solids in part of the Ensign drainage area stormwater

system since 2007 and sources of dry weather flow to the Ensign Outfall. This report

supplements information in the 2011 Source Control Evaluation Report for Stormwater and

Groundwater (Bridgewater and MFA, 2011) and the 2013 Addendum to Source Control

Evaluation Report Regarding Stormwater Pathway, Including Results of 2012 Catch Basin

and Sediment Trap Solids Sampling and Analyses (Bridgewater, 2013).

1.1 Purpose

In its June 27, 2014, letter, the DEQ described the actions required of DTNA to complete the

source control evaluation (SCE) for the TMP. Specifically, DEQ’s June 27 letter identified the

following remaining actions:

a. Continue your work evaluating potential additional BMPs.

b. Collect one first-flush and a standard storm event stormwater sample as

described in DEQ's Portland Harbor Joint Source Control Strategy (JSCS) and

supporting documents.

Key aspects of the sampling to keep in mind:

i. Samples should be evaluated for all contaminants of concern (COCs) in

order to allow for a full comparison of the results to past sampling results.

ii. It is critical to take all possible measures to achieve method detection limits

for total polychlorinated biphenyls (PCBs) that are below the JSCS criteria of

0.064 nanograms per liter (ng/L), or at least below the 0.033 micrograms per

liter (µg/L) lowest screening level value (SLV) for individual Aroclors. DEQ

understands that these are very low detection limits, but several other projects




have been able to achieve acceptable detection limits, using sample cleanup

procedures in the event of matrix interference.

c. Completion of the next video survey of solids in Fathom and Ensign storm

water pipes to assess if the fall 2013 solids removals from these pipes was complete

and if there are ongoing accumulation of solids occurring in the pipes.

d. Assuming these final actions show that source control goals have been achieved,

preparation of a report documenting the investigations and actions taken can

then be submitted to DEQ.

e. An important line of evidence that DEQ will use will be a comparison of the Truck

Plant contaminants of concern (COCs) to the sediment area of potential concern

(AOPC) #17 contaminants of concern. AOPC # 17 is the area where site storm

water eventually discharges to in the Willamette River. The AOPC 17 CoCs include:

As (arsenic), Cd (cadmium), Cu (copper), Hg (mercury), Ag (silver), tributyl tin (TBT),

Zn (zinc), PAHs (polycyclic aromatic hydrocarbons), di-n-butylphthalate (di-n-BP),

phenol, PCBs and dieldrin.

Accordingly, after a brief overview of the TMP’s stormwater system configuration, this report

is organized to address each of these required actions. Summary responses to each action

above are provided in Section 7.




2 Site Stormwater Conveyance System

Figure 3 shows the layout of the stormwater system at the TMP. Stormwater runoff at the site

is routed to 36 lined catch basins, four oil/water separators (OWSs) and a StormFilter™

filtration system, and then discharges to the City’s stormwater system via two outfalls (see

Figures 2 and 3). The four OWSs include two that discharge to the sanitary sewer at the

Maintenance and the Aboveground Storage Tank (AST) areas, one that receives discharge

from the former Water Leak Test and current Temporary Truck Containment area that

discharges to the stormwater system, and one that discharges to an infiltrating bioswale.

There is also a fifth OWS in a recirculating water system in the new dynamometer (DYNO),

but no stormwater enters this system and it discharges initially to the recirculation treatment

system and ultimately to the sanitary sewer

The site's two outfalls are located near North Fathom Street and North Ensign Street (Fathom

and Ensign Outfalls, respectively). Both outfalls are equipped with emergency cut-off valves

to prevent releases from leaving the property in the event of accidental spills to the

stormwater system. Twenty catch basins discharge to the Ensign Outfall. Two catch basins in

the Ensign drainage area discharge to the sanitary sewer system. Fourteen catch basins

discharge to the Fathom Outfall. Stormwater from the TMP discharges to the City’s

conveyance system in drainage basin M-1 and ultimately to Swan Island Basin of the

Willamette River via City Outfall M-1. City manhole AAJ831 is located downstream from the

Fathom Outfall in a cul-de-sac in North Fathom Street.




3 Summary of Stormwater Best Management

Practices

The TMP has a series of operational and structural best management practices (BMPs) in

place, and it has continued to refine its existing BMPs as well as implement new BMPs over

the course of the TMP SCE. Operational BMPs are discussed in this section and an updated

summary of existing BMPs is provided in Tables 1 and 2, including BMPs implemented after

DTNA’s June 2014 meeting with DEQ and the City. Table 1 indicates in bold font all actions

implemented or revised since this list was last submitted to the DEQ in DTNA’s December

2011 Source Control Evaluation Report (Bridgewater and MFA, 2011).

3.1 Operational Best Management Practices

The TMP has an employee education program designed to inform plant personnel of the

goals and components of the stormwater pollution control plan (SWPCP), the spill response

procedures and the necessity of good housekeeping practices. This training is provided, at

least annually, to all maintenance personnel, employees who handle oil products and

employees who conduct activities outside of the manufacturing plant near facility catch

basins. Employees new to these positions receive stormwater orientation training within

30 calendar days of hire. The catch basins at the TMP are covered with metal grates that

prevent large debris and solids from entering the storm sewer system. Each catch basin also

has had an oil-absorbent and suspended solids filter insert since as early as 1995.

Good housekeeping is practiced throughout the facility to reduce the amount of potential

pollutants, such as diesel, oil and grease, and debris, which might come into contact with

stormwater and/or might be discharged in stormwater. These housekeeping procedures

include the following:

The facility is swept at a minimum of once per month by an outside commercial industrial sweeper. Additional sweeping is performed as needed. DTNA uses its weekly inspections as the mechanism to call for sweeping with the on-site industrial sweeper and other targeted cleaning methods in areas where sweeping is needed. DTNA documents each time a service request is made for sweeping, although there are additional times that sweeping occurs in the course of plant maintenance without a service request. In addition, DTNA uses its “5S” work practices which require inspections and clean-up sweeping, as needed, in areas where the transportation of paint dollies occurs.

Employees are trained to keep working areas neat and stormwater catch basins clear.

Weekly site walks by the DTNA management team are conducted to inspect the facility and identify issues that require corrective actions, including those associated with the stormwater system.




Scheduled preventive maintenance is practiced to reduce the amount of potential pollutants

that might come into contact with stormwater and/or that might be discharged with

stormwater. Preventive maintenance at the TMP includes the following:

The StormFilter™ unit is inspected monthly with inspections documented on the StormFilter O&M form. The unit is serviced and cleaned, as necessary, based on monthly inspections, and at a minimum of once per year.

Routine maintenance of equipment and vehicles (e.g., forklifts) is performed to prevent leakage of oil, grease, and fuels.

Product dispensing and filling connections at the bulk solvent and fuel ASTs are inspected weekly for damaged or leaking connection points.

All areas around the storage tanks and maintenance areas are inspected weekly for accumulation of oil and grease and sediment.

All AST secondary containment structures are inspected weekly for integrity and are serviced by DTNA’s janitorial staff, as needed.

All stormwater catch basins are inspected monthly to ensure proper water flow, and debris and solids accumulated in the bottoms of the catch basins and on the metal cover-grates are removed quarterly, or more frequently as needed.

All stormwater catch basins are equipped with oil-absorbent catch basin filters, and filters are replaced quarterly, or more frequently as needed. Floating oil-absorbent booms or other devices are used, as needed, to minimize the potential for oil and grease to contact stormwater runoff.

The outfalls are inspected monthly by removing the manhole and vault covers and checking runoff for floating solids, color or foam, and oil and grease sheen.

All OWSs are inspected monthly for proper functioning. They are serviced quarterly by an outside contractor that is authorized to vacuum or pump out accumulated sediment, residual oil and grease, and other residual contaminants and debris, as needed. Valves related to stormwater piping, including the valve from the tank farm secondary containment structure and the valve for the sump in the truck secondary containment, are inspected weekly.

Spill-control equipment is inspected weekly to ensure that necessary equipment is available and in good condition.

Areas where industrial activities or potential spills of significant materials could impact stormwater runoff are inspected weekly.

Truck parts are moved, as needed, to allow sweeping in less accessible areas. For new truck components that are received in plastic packaging and temporarily stored in




uncovered areas, DTNA ensures that the plastic packaging is properly disposed of when it is removed. The roof of the facility is inspected a few times per year, and solids are removed, as necessary.

Routine inspections enable DTNA to provide timely and cost-effective repairs to equipment and stormwater control structures.

3.2 Structural Best Management Practices

Structural BMPs are discussed in this section and summarized in Table 2. The structural BMPs in place at the TMP property include the following:

Four OWSs, as discussed above.

StormFilter™ filtration system at the Ensign Outfall, which was selected for its ability to remove zinc. DTNA has continued to work with the StormFilter™ manufacturer to enhance the performance of the system, including usage of the most effective filter media (-CSF® Leaf Media) for zinc and other soluble metals.

Coating of the TMP's galvanized roof with a Neogard® cover. Neogard® is a closed cell, high-density urethane foam with a top coat designed to provide a continuous seamless cover. Thus, the new Neogard® cover prevents stormwater from coming into contact with the galvanized roof.

Bioswale and associated OWS for new truck parking area in the Offline yard.

Bioswale and water recirculating system at the new DYNO and new Water Test.

Enclosure of and/or containment of operations using and/or generating hazardous substances and/or hazardous wastes.

Enclosure of and/or containment of areas used for storage of hazardous substances and/or hazardous wastes.

DTNA has labeled catch basins with “No dumping, drains to river” or similar message in areas where such a message appears necessary based on the location of the catch basin and type of operations. In addition, as indicated above, catch basin inserts are used in all of the catch basins.

DTNA utilizes a Temporary Truck Containment Area for leaking trucks. As indicated above, the catch basin in that area is equipped with a valve to prevent discharge to the storm system when trucks are present in the containment area.

In 2012, an emergency cut-off valve was installed in the Ensign Outfall to minimize the potential for a release to migrate from the property.

In 2013, an emergency cut-off valve was installed in the Fathom Outfall to minimize the potential for a release to migrate from the property.




DTNA continues to identify opportunities for implementation of additional structural BMPs

which would result in an overall reduction of COCs in stormwater. In fact, DTNA has

committed to implement an additional structural stormwater treatment measure (i.e.,

construction of a larger onsite infiltration facility) that will address a National Pollutant

Discharge Elimination System (NPDES) 1200-Z stormwater permit second-year geometric-

mean zinc benchmark exceedence in the Fathom drainage basin to substantially eliminate

offsite stormwater discharges of zinc and other contaminants of concern (COCs) identified in

the SCE. Specifically, the bioswale in the Offline truck parking area will be expanded to

manage all runoff from the Fathom drainage basin (Drainage Area 1) of the TMP, as

discussed in DTNA’s December 22, 2014, Tier II Waiver Request and Alternative Tier II

Stormwater Pollution Control Plan Revision (MFA, 2014).




4 Additional Stormwater Sampling and

Analysis to Complete Source Control

Evaluation

4.1 Sampling Events Met DEQ’s Storm Event Criteria

The DEQ’s June 27, 2014, letter required DTNA to collect stormwater samples from each

outfall during two storm events, at least one of which was required to be a “first-flush” storm

event. DTNA has collected samples during three events. Specifically, it obtained three

samples at the Fathom Outfall that qualify as either “first flush” or standard samples, two

samples at the Ensign Outfall that qualify as either “first flush” or standard samples, and one

sample at the Ensign Outfall that qualifies as a standard sample event. Table 3 summarizes

the events relative to the DEQ’s required criteria for the collection of first-flush and standard

stormwater samples in the Stormwater Guidance. A description of each storm event follows.

4.1.1 October 13, 2014 Stormwater Sampling

Stormwater samples were collected at the Ensign and Fathom Outfalls (see Figure 3) during

a storm event on October 13 at 11:57 p.m. at the Ensign Outfall and at 11:22 p.m. at the

Fathom Outfall. Table 3 summarizes the event. Figure 4 is a hydrograph of the event.

Appendix A contains weather predictions. Appendix B contains field sampling data sheets

(FSDSs). Appendix C contains the laboratory analytical report and data quality

assurance/quality control review.

There was no rain in the proceeding 24 hours. The National Weather Service (NWS - NOAA)

predicted one-half inch of rain during a storm lasting at least three hours. These conditions

meet the Stormwater Guidance requirements of an antecedent dry period of at least 24 hours

(as defined by <0.1 inch over the previous 24 hours), minimum predicted rainfall volume of

greater than 0.2 inch per event, and expected duration of storm event of at least 3 hours. A

total of 0.39 inch of precipitation was recorded between 9 p.m. on October 13 and 7 a.m. on

October 14.

Bridgewater arrived onsite at 10:45 p.m. Flow was observed in the outfalls at 11:10 p.m. at

the Fathom Outfall and 11:13 p.m. at the Ensign Outfall. A sample was collected within 0.5

hour of flow in the Fathom Outfall and within 0.75 hour in the Ensign Outfall. This event meets

the Stormwater Guidance’s requirement for the collection of a sample within the 0.5 hour

(first-flush) of flow to the stormwater system for the Fathom sample. The Fathom sample

would also meet the requirements for a standard sample, since it was collected within three

hours of 11:10 p.m.. The Ensign sample almost meets the requirements for a first flush

sample, but not quite (0.75 hours after initiation of flow), so it is treated as a standard sample

taken within the first three hours of flow to the stormwater system.






a storm event on October 20 at 3:15 a.m. at the Ensign Outfall and at 3:05 a.m. at the Fathom

Outfall. Table 3 summarizes the event. Figure 5 is a hydrograph of the event. Appendix A

contains weather predictions. Appendix B contains the FSDSs. Appendix C contains the

laboratory analytical report and data quality assurance/quality control review.

No rain was recorded in the 24 hours prior to the sampled event. The NWS predicted 0.1 to

0.25 inch overnight between October 19 and October 20 and another 0.1 to 0.25 inch on

October 20. These conditions meet the Stormwater Guidance requirements of an antecedent

dry period of at least 24 hours (as defined by <0.1 inch over the previous 24 hours), minimum

predicted rainfall volume of greater than 0.2 inch per event, and expected duration of storm

event of at least 3 hours. A total of 0.45 inch of precipitation was recorded between 11 p.m.

on October 19 and 4 p.m. on October 20.

Bridgewater arrived onsite at 1:30 a.m on October 20. Flow was observed in the Fathom

Outfall at 3:05 a.m. and in the Ensign Outfall at 3:10 a.m. Samples were collected at 3:05

a.m. and 3:15 a.m., respectively. A sample was collected within 0.5 hour of flow in the

outfalls. As a result, this event meets the Stormwater Guidance’s requirements for the

collection of either a sample within 0.5 hour (first-flush) or the first three hours (standard) of

flow to the stormwater system.



a storm event on October 21 at 11:45 a.m. at the Ensign Outfall and at 11:10 a.m. at the

Fathom Outfall. Table 3 summarizes the event. Figure 6 is a hydrograph of the event.

Appendix A contains weather predictions. Appendix B contains the FSDSs. Appendix C

contains the laboratory analytical report and data quality assurance/quality control review.

Less than 0.1 inch of precipitation was recorded in the previous 24 hours. The NWS predicted

0.1 to 0.25 inch overnight between October 21 and October 22 and another 1 to 2 inches on

October 22. These conditions meet the Stormwater Guidance requirements of an antecedent

dry period of at least 24 hours (as defined by <0.1 inch over the previous 24 hours), minimum

predicted rainfall volume of greater than 0.2 inch per event, and expected duration of storm

event of at least 3 hours. A total of 1.39 inch of precipitation was recorded between 11 p.m.

on October 21 and 5 p.m. on October 22.

Bridgewater arrived onsite at 10:15 p.m on October 21. Flow was observed in the Fathom

Outfall at 11:05 p.m. and in the Ensign Outfall at 11:43 pm. at the Ensign Outfall. Samples

were collected at 11:10 p.m. and 11:45 p.m., respectively. A sample was collected within 0.5

hour of flow in the outfalls. As a result, this event meets the Stormwater Guidance’s




requirement for the collection of a sample within 0.5 hour (first-flush) and the first three hours

(standard) of flow to the stormwater system.

4.2 Analyses Performed as Required By DEQ

As requested, DTNA analyzed samples for all site-related COCs previously identified by

DEQ1 for this SCE to allow for comparison to all previous results.2 In addition, DTNA

analyzed samples for the “contaminants of concern to the sediment area of potential concern

(AOPC) #17,” as identified in DEQ’s June 27, 2014 letter. The AOPC #17 includes the Swan

Island Basin of the Willamette River in the Portland Harbor Superfund Site. Specifically, all

stormwater samples were analyzed for total and dissolved metals (arsenic, cadmium,

chromium, copper, lead, mercury, silver and zinc) by U.S. Environmental Protection Agency

(USEPA) Method 200.8/245.2; polycyclic aromatic hydrocarbons (PAHs), phthalates, and

phenol by USEPA Method 625; polychlorinated biphenyls (PCBs) and dieldrin by USEPA

Method 608; tributyltin (TBT) by SW3510C/SW8270D-SIM GC/MS and total suspended solids

(TSS) by USEPA Method 160.2. Field sampling data sheets are included in Appendix B.

Samples were analyzed at Specialty Analytical in Clackamas, Oregon. Tables 4 through 6

summarize the stormwater analytical results for the Ensign and Fathom Outfall samples. In

order to meet the low screening level values (SLVs) for arsenic, cadmium, PCB Aroclors and

carcinogenic PAHs in Appendix D of the Stormwater Guidance, Specialty Analytical reported

the analytical results to the lower method detection limits (MDLs) in addition to the higher

method reporting limits (MRLs). Concentrations detected between the MDL and MRL are

qualified with a J as estimated (see Tables 4 though 6). The laboratory analytical reports are

included in Appendix C. The data were reviewed for quality and were found to be acceptable

for use, with associated qualifiers assigned. The data quality review memorandum is included

in Appendix C.

4.3 Results

The stormwater results are presented in Tables 4 through 6, and are compared to both JSCS

SLVs and, where available, to the comparative industrial stormwater criteria (i.e., compared

against the DEQ’s “knee of the curve” on stormwater charts in Appendix E of the Stormwater

Guidance). Unfiltered stormwater data from Ensign and Fathom outfalls were evaluated using

the rank- ordered stormwater concentration charts found in Appendix E of the DEQ’s

Stormwater Guidance. The stormwater comparison charts were created by the DEQ using

“whole, unfiltered” contaminant concentration data from stormwater samples collected at

Portland Harbor area heavy industrial sites, and they are intended to be used as a screening

1 See April 21, 2006, Maul Foster and Alongi, Inc. Stormwater Evaluation Work Plan, Truck Manufacturing Plant, section 6.1, as revised by attachments to July 14, 2006, letter to Mike Romero that incorporated DEQ’s June 15, 2006, comments. 2 DTNA mistakenly did not analyze for hexavalent chromium, but it did test for total chromium. In all previous samples, hexavalent chromium has been significantly below the JSCS SLV.




tool for distinguishing typical industrial stormwater from stormwater containing potentially

elevated contaminant concentrations.

Concentrations of detected compounds including arsenic, BEHP, cadmium, total chromium,

copper, lead, zinc, total PAHs, and TSS from the Ensign and Fathom Outfalls were overlaid

on the DEQ Appendix E stormwater plots, and are included as Figures 7 through 14, which

show the most recent sample results and also show all previous TMP SCE stormwater

sample results. One plot is presented for each analyte. Site-specific data overlaid on the DEQ

concentration plot can fall into two curve regions:

Upper-steeper portion of the curve: concentrations falling in this vertical region of the curve are an indication that uncontrolled contaminant sources may be present.

Lower-flatter portion of the curve: concentrations falling in this horizontal region of the curve suggest that stormwater is not being unusually impacted by contaminants at the site and are therefore representative of “typical” industrial stormwater for Portland Harbor area properties (DEQ, 2010).

The exact limits of these two regions were purposefully undefined to avert misinterpretation of

the screening results. At the transition from horizontal to vertical shape, most concentration

charts have a distinctive “knee” area.

Non-detected stormwater concentrations from the Ensign and Fathom Outfalls were removed

to maintain consistency with the DEQ data used to create the charts. Also, J-flagged data,

indicating that concentrations were estimated by the laboratory, were plotted as real data

points at face value.

Analytes are discussed below, in each case addressing the specific concerns raised in DEQ’s

June 27, 2014 letter.

4.3.1 Polychlorinated Biphenyls

DEQ’s June 27 letter acknowledged that PCBs had not been detected in previous stormwater

samples, but requested additional confirmatory sampling and analysis, with detection limits

below the JSCS criteria “or at least below the 0.033 µg/L lowest SLV for individual PCB

Aroclors.” As shown in Tables 4 and 5, PCBs were not detected in any samples. Detection

limits for individual PCB Aroclors ranged from <0.00368 µg/L to <0.00451 µg/L, an order of

magnitude lower than the required limit.

Thus, this additional sampling has confirmed the absence of PCBs in TMP stormwater

discharges.




4.3.2 Copper, Lead and Zinc

DEQ’s June 27 letter acknowledged that copper, lead and zinc, as measured in the more

recent DTNA samples, had been at “concentrations that are within comparative industrial

stormwater criteria (i.e. ‘below the knee of the curves’) and likely do not require further

stormwater controls.” DEQ stated that it would evaluate the results from these additional

sampling events to determine if sources of these chemicals are still below levels of concern.

As shown in Tables 4 and 5 and in Figures 7, 8 and 9, concentrations in these additional

sampling events remained below the knee of the curve, in the horizontal portion of the chart.

Additionally, all trend to the low end of previous concentrations. With respect to zinc, all

measured concentrations are well below the knee of the curve, and four of the six samples

were at the low end of previous concentrations, while two of the six samples were in the same

range as previous data. As noted in Section 3, DTNA has committed to implement an

additional stormwater treatment measure (i.e., construction of a larger onsite infiltration

facility) for zinc to substantially eliminate all off-site stormwater discharges containing zinc and

other COCs from the Fathom drainage basin. Specifically, the bioswale in the Offline truck

parking area will be expanded to manage all runoff from the Fathom drainage basin (Drainage

Area 1) of the TMP, as discussed in DTNA’s December 22, 2014, Tier II Waiver Request and

Alternative Tier II Stormwater Pollution Control Plan Revision (MFA, 2014).

Thus, this additional sampling has confirmed that copper, lead and zinc are not present at

levels of concern in TMP stormwater and/or will not be discharged from the Fathom Outfall

following installation of the new stormwater infiltration facility, which is anticipated to occur by

June 30, 2016, at the latest.

4.3.3 Polycyclic Aromatic Hydrocarbons

DEQ’s June 27 letter also acknowledged that PAHs, as measured in past stormwater

samples, had been at “concentrations that are within comparative industrial stormwater

criteria (i.e. ‘below the knee of the curves’) and likely do not require further stormwater

controls. Similar to copper, lead and zinc, DEQ asked DTNA to confirm this by analyzing

samples for PAHs during these additional sampling events.

As shown in Tables 4 and 5 and in Figure 10, individual and total PAH concentrations in these

additional sampling events remained far below the knee of the curves in Appendix E of DEQ’s

Stormwater Guidance, plotting in the horizontal portion of the chart. Thus, this additional

sampling has confirmed that PAHs are not present at levels of concern in TMP stormwater.

4.3.4 Cadmium

DEQ’s June 27 letter noted that DTNA would need to show that its additional BMPs have

resulted in better control of cadmium, to be demonstrated both through stormwater

measurements, discussed here, and in-line solids inspections, discussed in Sections 5 and 6

of this report.




The concentrations of total cadmium in stormwater from the October 2014 sampling events

ranged from 0.085 J µg/L to 0.421 µg/L. This range is below the range of prior sampling

events (0.113 µg/L to 2.5 µg/L) and below the knee of DEQ’s curve (see Figure 11),

demonstrating the positive impact of DTNA’s enhanced BMPs. Dissolved cadmium

concentrations showed the same trend with the October 2014 results ranging from non-detect

at 0.0518 µg /L to 0.283 µg/L, as compared to the range of previous results between 0.09 J

µg /L and 0.97 µg/L.

Although concentrations of dissolved cadmium were generally not below the JSCS SLV of

0.094 µg/L, the concentrations of total cadmium are below the estimated range of the “knee”

of stormwater curves in Appendix E of the DEQ’s Stormwater Guidance (i.e., 0.5 µg/L to 1.5

µg/L). Of note, the recent cadmium concentrations, overlaid on the DEQ’s curve, similarly

show a trend of improvement resulting from implementation of enhanced BMPs over time.

Most of the Ensign and Fathom Outfall cadmium data from 2007 through 2011 plot in the

middle, knee portion of the curve, with two of the earlier samples (from the Fathom Outfall, in

2007 and 2009) plotting in the upper vertical portion of the curve (see Figure 11). However, all

of the more recent data (collected in October 2014) plot below the lower portion of the knee

and in the horizontal portion of the curve, indicating that additional source control is not

necessary for this metal (see Figure 11). As noted above in Section 4.3.2, DTNA will be

implementing an NPDES-1200Z Tier II corrective action measure before June 30, 2016; this

measure includes expansion of an existing bioswale and infiltration of all stormwater runoff in

the Fathom drainage area. Thus, cadmium will not be discharged from the Fathom Outfall

following installation of the new stormwater infiltration facility.

4.3.5 Bis-2-Ethylhexyl-Phthalate and Other Phthalates

DEQ’s June 27 letter noted that DTNA would need to show that its additional BMPs have

resulted in better control of BEHP, to be demonstrated both through stormwater

measurements, discussed here, and in-line solids inspections, discussed in Section 5. BEHP

is not a COC in the sediment area of potential concern (AOPC #17) to which this stormwater

discharges.

The concentration of BEHP in stormwater from the October 2014 sampling events ranged

from 0.405J µg/L to 6.25 µg/L. The high concentration was measured in a sample collected

from Ensign Outfall on October 13 that contained 62 milligrams per liter (mg/L) of TSS, which

is unusually high when compared to all other sample results at the TMP (see Tables 4 and 5

and Figure 13). Other than that one outlier, results trended lower than prior sampling events

(which ranged from 0.181J µg/L to 19.7 µg/L) again demonstrating the impact of DTNA’s

enhanced BMPs. Three out of six results were above the JSCS SLV of 2.2 µg/L (see Figure

12). All October 2014 results, except the 6.25 µg/L October 13 result, are at the low end of the

“knee of the curve” of the DEQ’s stormwater curve in Appendix E of the Stormwater Guidance

(i.e., 4 µg/L to 10 µg/L) or in the flat area below the knee. Although there continues to be




variability in BEHP concentrations in TMP stormwater data, the variability is over a much

lower concentration range, generally falling in the low end of the knee or below the knee of

the curve. Thus, this additional sampling has confirmed that TMP has achieved control of

BEHP discharges.

After the 6.25 µg/L October 13 result, the next highest concentrations of BEHP have been

detected in the Fathom Outfall. As noted above in Section 4.3.2, DTNA will be implementing

an NPDES-1200Z Tier II corrective action measure before June 2016; this measure includes

the expansion of an existing bioswale and infiltration of all stormwater runoff in the Fathom

drainage area. Consequently, this corrective action will substantially eliminate stormwater

discharges from the Fathom drainage area including BEHP discharges.

DTNA also analyzed the samples for other phthalates. As shown in Tables 5 and 6, these

were all either not detected or were detected below the JSCS SLV with two exceptions. One

sample from the Ensign Outfall contained 7.44 µg/L of dimethylphthalate and the other two

samples contained 0.219J µg/L and 0.642J µg/L, well below the SLV of 3.0 µg/L. A different

sample from the Ensign Outfall contained 6.0 µg/L of di-n-octylphthalate (and the other two

results were non-detect). Neither of these phthalates is a COC for AOPC #17. While di-n-BP,

a COC for AOPC#17, was detected in four samples, detected concentrations were about an

order of magnitude less than the SLV of 3.0 µg/L.

4.3.6 Other Contaminants of Concern for Area of Potential Concern 17 in

Portland Harbor Superfund Site

DEQ’s June 27 letter stated that an important line of evidence for conclusion of the SCE

would be a comparison of the TMP site-specific COCs to the COCs for AOPC #17, the

ultimate discharge point for stormwater from the TMP via the City’s M-1 Outfall. DEQ

identified the AOPC #17 COCs as arsenic, cadmium, copper, mercury, silver, TBT, zinc,

PAHs, di-n-BP, phenol, PCBs, and dieldrin. Of these, cadmium, copper, zinc, PAHs, PCBs,

and di-n-BP have all been addressed above. None of the remaining COCs have been

identified as COCs associated with the TMP. Nonetheless, DTNA analyzed for them in the

October 2014 sampling events to confirm their absence.

The following were either not detected or not detected above their respective JSCS SLVs:

mercury, silver, TBT, phenol and dieldrin (see Tables 4 and 5). The method detection limit

(MDL) for dieldrin exceeded the SLV, but was the lowest available. Again, none of these

substances is a COC for the TMP.

Total arsenic was detected in three out of the six samples. Concentrations ranged from 0.340

J µg/L to 0.740 µg/L (see Tables 4 and 5 and Figure 14). The applicable water quality

standard for arsenic in Oregon is now 2.1 µg/L for total inorganic arsenic (see OAR 340-041-

0033, Table 40). No further action is required to address arsenic because the measured

concentrations are below the applicable water quality standard, concentrations plot below the




“knee of the curve” of the DEQ’s stormwater curve in Appendix E of the Stormwater

Guidance, and it is not a COC for the TMP.




5 Results of 2014 Video Camera Survey of

Portions of Fathom and Ensign Stormwater

Conveyance Systems

As requested in DEQ’s June 27 letter, DTNA performed video camera surveys in portions of

both the Fathom and Ensign stormwater lines. In the Fathom line, the survey was performed

in accordance with the October 10, 2013, Sampling and Analysis Plan (SAP) to evaluate

possible reaccumulation of solids in the line between the Fathom Outfall and City manhole

AAJ831 since the November 2013 cleanout (Pacific Groundwater Group [PGG], 2013). In the

Ensign line, the video camera survey was performed to investigate possible reaccumulation in

the line since the 2006-2007 cleanout and possible sources of dry weather flow to the lateral

from the southeast part of the facility. The following sections summarize the results.

5.1 Fathom Line Video Camera Survey

As noted in Section 2.3 of the SAP, it was planned that a second video camera survey of the

line between the Fathom Outfall and City manhole AAJ831 would be performed

approximately four months after the November 2013 line cleanout to determine if solids were

re-accumulating. Because of the relatively dry fall and winter of 2013 that the Portland area

experienced until February 2014, DTNA recommended that the post-cleanout camera survey

be performed in June or July of 2014. During a February 5, 2014, meeting, the DEQ agreed

with this recommendation. The video camera survey was further delayed due to facility

operations. The post-cleanout camera survey was performed on October 2, 2014, by Pacific

INT-R-TEK. The video and log is included in Appendix D.

The post-cleanout camera survey revealed the following:

The installation of the cut-off valve in a vault immediately downstream of the Fathom Outfall in 2013 has created a settling vault for larger solids. Solids have to be suspended in the water column to make it over an 8-inch-high barrier/joint into the main line to the City’s line. An estimated one to two inches of solids had accumulated in this vault in areas away from the center of the vault where the flow enters it from the Fathom Outfall.

Dry weather flow was observed from the east Fathom lateral to the TMP facility indicating that there are likely continued, intermittent discharges of potable water from the humidification systems associated with the paint booths. As previously reported in the January 20, 2014, Results of Dry Weather Flow Investigation to Fathom Outfall, which was shared with the City of Portland, this flow is of potable water, which discharge is authorized under condition 7.a.iii of the DTNA’s NPDES 1200-Z permit.

Medium- to coarse-grained, sand-sized solids were observed in the line downstream of the cut-off valve vault. Solids appeared to be primarily from roofing material (as interpreted by the camera crew) with some paint chips between 0 and




63 feet from the Fathom cut-off valve vault. An estimated 0.5 inch of solids was present in the bottom of the pipe.

The volume of solids increased at about 63 feet downstream from the cut-off valve vault where a low point in the line begins. While sand-sized material and paint chips were observed, there was also finer-grained, silt-sized material present that was “stirred up” by the camera while travelling down the line. The thickness increased to an estimated three inches between 63 and 75 feet and then decreased to two inches between 75 and 90 feet from the Fathom cut-off valve vault.

The results indicate that there are limited quantities of solids present in the Fathom drainage

area that are bypassing the catch basin inserts or coming from roof drains similar to other

sites. Based on DTNA’s TSS stormwater results, DTNA has significantly reduced the amount

of suspended solids in its stormwater discharge, although it cannot eliminate them entirely. It

has, however, reduced TSS concentrations significantly below the allowed TSS benchmark in

its NPDES 1200-Z permit. Further, as shown in Figure 13, DTNA currently does a better job

than most industrial permittees in Portland Harbor in reducing the amount of solids that are

discharged from its stormwater system.

Further, through the implementation of the NPDES Tier II actions described above, by June

2016 or earlier, DTNA will have substantially eliminated off-site stormwater discharges from

the Fathom drainage area. Once the bioswale expansion is completed, suspended solids in

the Fathom drainage area will be contained in the bioswale and not discharged from the site.

5.2 Ensign Line Video Camera Survey

Intermittent dry weather flow has been observed in a lateral to the Ensign Outfall from the

southeast part of the site (see Figure 3). This area receives discharges from roof drains and

paved areas near Dock 1 and from stormwater lines that run under the wastewater treatment

plant (WWTP). The line was surveyed on September 30, 2014 and October 7, 2014 by Pacific

INT-T-TEK. The line was relatively free of solids. Although flow was observed, the amount of

flow, a trickle, was too small to sample.

Two potential sources of dry weather flow were observed. There may be some groundwater

intrusion into a connection between two stormwater lines under the WWTP inside the

building; these pipes pre-date the construction of the WWTP in 2002 and are likely connected

to old roof drains added to the building during the 1984-1985 expansions. The video shows

that groundwater intrusion was occurring where one pipe connects to the main line, similar to

a T joint. In addition, there was a small amount of flow in the main line from an undetermined

source upstream of the connection of the above pipe to the main line, but the camera could

not be advanced any farther up the line due to the number of bends in the pipe. Process

water cannot enter these lines or the subsurface because the floor of the WWTP is coated




with epoxy to prevent fluids from entering the subsurface. The floor is designed to contain any

potential overflows, and no fluids are allowed to accumulate on the floor.

If the source of the dry weather flow is groundwater, groundwater is not impacted by site-

related COCs and is therefore not of concern for the SCE. Reconnaissance samples of

shallow groundwater collected in 2003 did not contain any volatile organic compounds, and

PAH and metals concentrations were below the JSCS SLVs and state ambient water quality

criteria (see Tables 6-12 through 6-14 and Figure 2-9, locations WF-5 through WF-7 and EF-

3, of the 2009 Remedial Investigation Report [MFA, 2009]).




6 Results of 2014 Post-Video Survey Fathom

Storm Line Solids Sampling and Analysis

Pursuant to the October 10, 2013 SAP and similar previous storm line solids sampling and

analyses, solids were collected from the 30-inch-diameter stormwater line downstream of the

Fathom Outfall between the cut-off valve vault and City manhole AAJ831 on October 10,

2014. These solids samples were collected to evaluate if the observed solids accumulating in

the Fathom stormwater line since November 2013 contain COCs for the stormwater SCE.

6.1 2014 Solids Sampling

On October 10, 2014, personnel with confined space training from Terra Hydr, Inc. entered

the cut-off valve vault manhole, walked down the sides of the pipe above the water line so as

not to disturb the solids, and sampled solids from 90 feet (adjacent to City manhole AAJ831)

upstream to the cut-off valve vault to minimize disturbing downstream materials. In-line solids

sample locations were determined by measuring the linear distance from the cutoff valve vault

(immediately downstream from the Fathom Outfall) with sample names reflecting the distance

downstream from the cut-off valve vault (e.g., Fathom 0-16 represents a sample collected

between 0 and 16 feet downstream of the cut-off valve vault). The samples were collected

inside the cut-off valve vault and from the pipe between the cut-off valve vault and City

manhole AAJ831. Consistent with the previous sampling, field personnel instructed the

analytical laboratory to homogenize each sample. FSDSs are included in Appendix E.

On the basis of the presence of solids, six in-line solids samples were collected at the

locations summarized in Table 7. Solids samples were collected in new, clean, laboratory-

supplied, 4 ounce, glass containers, packed in laboratory-supplied coolers, and filled with ice

as a temporary sample preservative. Samples were delivered to the analytical laboratory,

Specialty Analytical in Clackamas, Oregon, under chain-of-custody documentation. Samples

were analyzed for total cadmium, chromium, copper, lead, and zinc by USEPA Method

6010C; PCBs by USPEA 8082A; PAHs by USEPA 8270D SIM; and phthalates by USEPA

8270D.

6.2 2014 Storm Line Solids Results

Analytical results are summarized in Table 8 and included in Appendix F. Table 8 provides a

comparison of the 2014 concentrations to those in the line before the initial cleaning of the

Fathom storm lines in February 2007 and September 2010. In addition, the results are

compared to those collected in October 2013 before a thorough cleaning of the line between

the Fathom Outfall and City manhole AAJ832 conducted by DTNA in November 2013. Finally,

solids concentrations from samples collected from City manhole AAJ831 in 2003, 2009, and

2013 are also included for comparison. The data indicate that COC concentrations have

decreased substantially.

Analytical data were reviewed for quality and validated as documented by Proud Data

Services, on behalf of Bridgewater. The data are acceptable for use with appropriate




qualifiers assigned (see Appendix F for the Data Quality Assurance/Quality Control Review

Memorandum for more information).

6.2.1 Polychlorinated Biphenyls

Aroclor 1254 had been previously detected in solids removed from storm lines in the Fathom

drainage area and in City manhole AAJ831 (see Table 8), with concentrations ranging from

4.9 J micrograms per kilogram (µg/kg) in samples collected 23 feet downstream of the

Fathom Outfall in 2013 to 1,840 µg/kg in the solids removed from the storm lines in the

Fathom drainage area in 2007. But in October 2014, PCBs were not detected in any of the

solids samples collected between the Fathom cut-off valve vault and City manhole AAJ831

(see Table 8). The detection limit (0.33 µg/kg) is almost two orders of magnitude lower than

the SLV of 300 µg/kg for individual Aroclors. This absence of PCBs in solids is consistent with

the absence of PCBs in the stormwater samples discussed above in Section 4.

6.2.2 Copper, Lead and Zinc

Detected concentrations of copper, lead and zinc have exceeded the JSCS SLVs in the solids

removed from the lines in the Fathom drainage area and in City manhole AAJ831 (see Table

8). Historically, detected concentrations of copper ranged from 97,600 µg/kg in a sample

collected 60 feet downstream of the Fathom Outfall in 2013 to 479,000 µg/kg in a sample

collected 33.2 feet downstream of the Fathom Outfall in 2013. In 2014, detected copper

concentrations between the Fathom Outfall and City manhole AAJ831 were generally lower

than those measured before the 2013 cleanout and lower than those detected in City

manhole AAJ831 before the 2013 cleanout. Moreover, they are all below the DEQ’s

Stormwater Guidance’s “knee of the curve” for copper in stormwater sediments at industrial

sites in Portland Harbor.

Historically, detected concentrations of lead ranged from 6,690 µg/kg in a sample collected in

a stormwater line under the Offline area inside the TMP in 2010 to 587,000 µg/kg in solids

removed from the storm lines in the Fathom drainage area in 2007 (see Table 8). Similar to

copper, lead concentrations in 2014 were lower than those detected before the 2013 cleanout

and lower than those detected in City manhole AAJ831 before the 2013 cleanout.

Similar trends were observed for zinc; concentrations of zinc in 2014 were lower than those

detected before the 2013 cleanout (see Table 8). Detected concentrations of lead and zinc

are also below the Stormwater Guidance’s “knee of the curves” for lead and zinc in

stormwater sediments at industrial sites in Portland Harbor.

These decreasing concentration trends in the solids are consistent with the stormwater data

for copper, lead and zinc discussed above in Section 4, where concentrations are all below

their respective “knee of the curves” in the stormwater charts in Appendix E of DEQ’s

Stormwater Guidance.




6.2.3 Polycyclic Aromatic Hydrocarbons

DEQ’s June 27 letter acknowledged that PAHs in stormwater likely did not require further

stormwater controls. This conclusion is also supported by the 2014 solids data. No PAH

concentrations in solids collected between the Fathom cut-off valve and City manhole AAJ831

in 2014 exceeded the SLVs, where available (see Table 8).

6.2.4 Cadmium

Cadmium has been detected in solids removed from the storm lines in the Fathom drainage

area and in City manhole AAJ831 (see Table 8). Detected concentrations of cadmium have

exceeded the JSCS SLV of 1,000 µg/kg. Historically, cadmium concentrations ranged from

2,590 µg/kg in a 2013 sample collected between 63 and 75 feet downstream of the Fathom

cut-off valve vault to 53,300 µg/kg in a 2010 sample collected under the Offline area of the

TMP (see Table 8). Concentrations in 2014 were lower than those measured in the storm

lines before the 2013 cleanout and much lower than those measured in solids removed from

storm lines in the Fathom drainage area in 2007 and 2010 (see Table 8). This is consistent

with the observed decreases in cadmium concentrations in stormwater as discussed above in

Section 4.

6.2.5 Bis (2-ethylhexyl) Phthalate and Other Phthalates

Phthalates have been detected in solids removed from the Fathom drainage area and in City

manhole AAJ831 (see Table 8). Di-n-butylphthalate and BEHP concentrations exceeded the

JSCS SLVs. The 2014 BEHP concentrations were similar to the 2013 concentrations between

the Fathom Outfall and City manhole AAJ831, except the concentration near City manhole

AAJ831 is 63 percent lower than before the cleanout in 2013 (14,400 µg/kg versus 39,000

µg/kg) and 71 percent lower than the concentration in the June 2013 City manhole AAJ831

sample (14,400 µg/kg versus 49,000 µg/kg) (see Table 8).

6.2.6 Decreased Total Suspended Solids as Indicator of Effective BMP

Implementation and Reduction in COC Loads in Solids

It is important to note that, during this same 2007 to 2014 time period for the SCE, DTNA has

very effectively reduced the total amount of solids getting into its stormwater system. For

example, the average TSS concentration for DTNA’s NPDES 1200-Z stormwater samples

collected between from 1993 until 2007 (when the first stormwater line cleanout was

performed) was 41.9 milligrams per liter (mg/L). Since 2007, the average TSS concentration

has been 8.2 mg/L. Figure 13 shows DTNA’s TSS concentrations from all SCE samples

relative to heavy industrial sites in Portland Harbor. Almost all results plot in the flat portion of

the curve, showing that DTNA does a very good job of controlling solids, as compared to

other industrial sites. During this time, DTNA also installed the emergency cut-off valve in a

vault downstream of the Fathom Outfall. This vault includes an approximate 8-inch-high

lip/joint, which acts as an additional solids trap before stormwater leaves the DTNA property.




These observations regarding solids are consistent with the stormwater data discussed in

Section 4. The BMPs implemented by DTNA have resulted in both a decrease in the amount

of solids getting into the stormwater system and a decrease in COC concentrations in the

solids that get into the system. Improved stormwater quality at the TMP is the result of the

stormwater control measures and BMPs discussed in Section 3.




7 Summary

DTNA has completed all steps required in the DEQ’s June 27, 2014, letter for the evaluation

of the stormwater pathway and completion of the SCE at the DTNA TMP facility. The

following scopes of work were required in the DEQ’s June 27 letter. DTNA's responses are

provided in bold.

a. Continue your work evaluating potential additional BMPs .

Response: DTNA’s operational and structural BMPs are summarized in Section

3 and Tables 1 and 2 of this report.

b. Collect one first-flush and a standard storm event stormwater sample as

described in DEQ's Portland Harbor Joint Source Control Strategy (JSCS) and

supporting documents. Key aspects of the sampling to keep in mind:

i. Samples should be evaluated for all contaminants of concern (COCs) in order to allow for a full comparison of the results to past sampling results. It is critical to take all possible measures to achieve method detection limits for

total polychlorinated biphenyls (PCBs) that are below the JSCS criteria of

0.064 ng/L, or at least below the 0.033 ug/L lowest SLV for individual

Aroclors. DEQ understands that these are very low detection limits, but

several other projects have been able to achieve acceptable detection limits,

using sample cleanup procedures in the event of matrix interference.

Response: Bridgewater collected first-flush and standard storm event

samples on October 13, 20, and 21, 2014. The results are summarized in

Section 4 of this report. PCBs were not detected in any samples.

Detection limits for individual PCB Aroclors ranged from <0.00368 µg/L

to <0.00451 µg/L, an order of magnitude lower than the required limit.

This additional sampling has confirmed the absence of PCBs in TMP’s

stormwater discharges. Concentrations of copper, lead, zinc, cadmium,

and PAHs in these additional samples are below the knee of the DEQ’s

stormwater curves for heavy industrial sites in the Portland Harbor,

plotting in the horizontal portion of the charts. Concentrations of BEHP

have also decreased, with five of six samples below the knee of the

curve or in the very low portion of the knee. Importantly, BEHP is not a

COC in AOPC #17. Further, DTNA has committed to implement an

additional stormwater treatment measure (i.e., construction of a larger

onsite infiltration facility) to manage all runoff from the Fathom drainage

basin (Drainage Area 1) of the TMP. Stormwater in the Fathom drainage

area will be managed onsite via infiltration on or before June 30, 2016,




thereby lowering concentrations of these COCs in TMP’s stormwater

discharges.

c. Completion of the next video survey of solids in Fathom and Ensign stormwater

pipes to assess if the fall 2013 solids removals from these pipes was complete

and if there are ongoing accumulation of solids occurring in the pipes.

Response: The video survey of the Fathom Outfall to City manhole AAJ831

was performed on October 2, 2014 (see Section 5 of this report). The results

of the video survey and a copy of the DVD are included in Appendix D. Solids

were observed in the storm line. Solids were sampled on October 10, 2014

(see Section 6 of this report). No PCBs were detected, and the detection

limits were at concentrations below the JSCS SLVs for individual Aroclors,

where available. Site-related COCs including cadmium, copper, lead and zinc,

PAHs and phthalates were detected in the solids. The 2014 data indicate that

site-related COC concentrations in the solids getting into the stormwater lines

are lower than previous levels in the Fathom line and in City manhole AAJ831

and fewer solids are getting into the stormwater system.

A video survey of that portion of the Ensign stormwater line where dry

weather flow has been observed was performed on September 30 and

October 7, 2014 (see Appendix D of this report). The source of the dry

weather flow may be groundwater intrusion at the joint between two pipes

under the WWTP. The amount of flow was insufficient to sample. Note that

groundwater quality in inferred downgradient locations from this area is not

adversely impacted with site-related COCs on the basis on reconnaissance

samples collected in 2003. Therefore, no further action is recommended.

d. Assuming these final actions show that source control goals have been achieved,

preparation of a report documenting the investigations and actions taken can then

be submitted to DEQ.

Response: Documentation of the final actions is included in this report.

e. An important line of evidence that DEQ will use will be a comparison of the Truck Plant contaminants of concern (CoCs) to the sediment area of potential concern (AOPC) #17 contaminants of concern. AOPC #17 is the area where site stormwater eventually discharges to in the Willamette River. The AOPC 17 CoCs include: As, Cd, Cu, Hg, Ag, tributyl tin, Zn, PAHs, di-n-butylphthalate, phenol, PCBs and dieldrin.

Response: Of these, cadmium, copper, zinc, PAHs, and PCBs have all been

addressed above. None of the remaining COCs have been identified as COCs

associated with the TMP. Nonetheless, DTNA analyzed for them in the October

2014 sampling events to confirm their absence. The following were either not

detected or not detected above their respective JSCS SLVs: mercury, silver,

TBT, phenol, dieldrin, and di-n-butylphthalate. The MDL for dieldrin exceeded




the SLV, but was the lowest available. Total arsenic was detected in three out of

the six samples; concentrations ranged from 0.340 J µg/L to 0.740 µg/L. No

further action is required to address arsenic because the measured

concentrations are below the applicable water quality standard, concentrations

plot below the “knee of the curve” of the DEQ’s stormwater curve in Appendix E

of the Stormwater Guidance, and it is not a COC for the TMP.




8 Recommendations

No further source control evaluations or actions are necessary. DTNA recommends that DEQ

prepare a Source Control Decision for the TMP.

Notes

Concentration > JSCS SLV

Bold = analyte detected.

mg/L = milligrams per liter.

NA = not applicable.

NPDES = National Pollutant Discharge Elimination System.

NV = no value.

SLV = screening level value

U = analysis conducted, but analyte not detected above reported sample quantitation limit.


J = analyte was positively identified; associated numerical value is approximate concentration between the method detection limit and method reporting limit.

JSCS Screening Level Value (ug/L)

The source of each screening level value is documented in Table 3.1 of the Portland Harbor JSCS, which can be viewed at http://www.deq.state.or.us/lq/cu/nwr/PortlandHarbor/docs/JSCSFinalTable03_1.pdf . Values for cadmium,

copper, hexavalenet chromium, lead, mercury, and zinc apply to dissolved concentrations.

At Portland Harbor sites, drinking water maximum contaminant levels and preliminary remediation goals are also used as screening levels, per the Joint Source Control Strategy (JSCS). These values are applied when they are lower than

all other screening values.

Weather Predictions for October 2014 Stormwater Sampling Events

From: Mike MurrayTo: [email protected]; Tony SilvaCc: "Ben"; "Jane-Clair Kerin"Subject: RE: Stormwater Sampling at Western Star TMP This Weekend - Next Week?Date: Sunday, October 19, 2014 2:53:43 PM

Hi Anna, I’m not sure how to interpret this (updated just now for this evening):

Tonight: Rain likely, mainly after 11pm. Mostly cloudy, with a low around 56. South wind 7 to 10 mph, with gusts as highas 20 mph. Chance of precipitation is 70%. New precipitation amounts between a tenth and quarter of an inch possible.

Monday Showers. High near 60. South wind 5 to 9 mph. Chance of precipitation is 100%. New precipitation amountsbetween a tenth and quarter of an inch possible.

Monday Night A 50 percent chance of showers. Mostly cloudy, with a low around 51. South southwest wind 7 to 9 mph.New precipitation amounts of less than a tenth of an inch possible.

Tuesday A 30 percent chance of rain. Mostly cloudy, with a high near 59. South wind around 8 mph. New precipitationamounts of less than a tenth of an inch possible.

I know DEQ wants a predicted amount of >0.2”, should we proceed with the sampling? If we waituntil an event with large amounts of precip predicted, it is likely we will be outside of the 24 hourdry period. Any thoughts? Thanks! MICHAEL R. MURRAY RG, LG | MAUL FOSTER & ALONGI, INC.

Happy Saturday! Thanks for being available! You’ll probably need three other peeps so one group is at Fathom andone is at Ensign. I cc:d Ben and Jane at Hahn to see if they are available to help too. Should I askScout too? It takes a village. Here is the forecast for Sunday-Monday

Sunday Night Rain likely, mainly after 11pm. Mostly cloudy, with a low around 54. South wind around 7 mph.

mailto:[email protected]





file:////c/www.maulfoster.com%20

Chance of precipitation is 60%.

Monday Showers, with thunderstorms also possible after 11am. High near 61. South wind 3 to 5 mph. Chance of

precipitation is 90%. New rainfall amounts between a quarter and half of an inch possible.

Not sure about Sunday night. If it stops between Sun night and Monday, Monday would be betterb/c they are predicting new rainfall amounts between 0.25-.5 inch. These are the same two sites we sampled, Tony. Fathom and Ensign. Sample Fathom from lateralcoming in from NW. Sample Ensign from that black curtain thing to the right of cutoff valve and noteweather water is flowing over that weir. Samples need to be analyzed for: Metals – total and dissolved (Cd, Cu, Zn, As, Hg, Ag). Use white poly for TSS and dissolved metals andlab will filter.TSSPAHs (1 amber)PCBs (1 amber)Phthalates (1 amber)Phenols (1 amber)TBT (1 amber)Dieldrin (1 amber) Cd RL/MDL < 0.094 ug/LCPAHS < 0.018 ug/L TAT = 3-5 days They need to go to Specialty. I’ll leave the bottles on my front porch. I would label the bottles ahead of time to make it easier. Wetypically label them as follows: FAT-102014 (or whatever the dates ends up to be) and ENS-102014. I’ll check in later tomorrow once I get to Tucson. Give me a call on my cell with any ???

Laboratory Analytical Reports and Data Quality Assurance/Quality Control Memorandum for October 2014

Stormwater Sampling Events

DTNA-001-14Oct-QAQC-water.doc PAGE 1

DATA QUALITY ASSURANCE/

QUALITY CONTROL REVIEW PROJECT NO. DTNA-001 | NOVEMBER 12, 2014 | DAIMLER TRUCKS NA

This report reviews the analytical results for two water samples collected by the Bridgewater Group, Inc. at the Western Star Truck Manufacturing Plant on October 13, 2014 in Portland, Oregon.

Specialty Analytical Labs (SA) in Clackamas, Oregon performed most analyses. SA sent samples to Neilson Research Corporation (NRC) in Medford, Oregon for USEPA 200.8 analysis and to Analytical Resources, Incorporated (ARI) in Tukwila, Washington for tributyltin analysis by USEPA SW8270D. SA order number 1410089, NRC order number 1410655, and ARI job number ZF78 were reviewed. The analyses performed are listed below.

Analysis Reference

Metals, Dissolved Recoverable USEPA 200.8

Metals, Total Recoverable USEPA 200.8

Mercury, Total Aqueous USEPA 245.2

Mercury, Dissolved Aqueous USEPA 245.2

Polycyclic Aromatic Hydrocarbons (PAHs) USEPA 625

Base/Neutrals and Acids USEPA 625

Organochlorine Pesticides and PCBs USEPA 608

Tributyltin USEPA SW8270D

Total Suspended Solids SM 2540D

USEPA = U.S. Environmental Protection Agency

SM = Standard Methods for the Examination of Water and Wastewater

DATA QUALIFICATIONS

Analytical results were evaluated according to applicable sections of USEPA procedures (USEPA, 2008, 2010) and appropriate laboratory and method-specific guidelines (SA, 2012; APHA, 2012).

The data are considered acceptable for their intended use, with the appropriate data qualifiers assigned.

DOCUMENTATION AND TRANSPORT

Samples were transported under strict chain-of-custody (COC) procedures. ARI reported that samples received from SA for tributyltin analysis arrived at 9.3 °C, over the recommended maximum of 6 °C. The stability of the compound and its resistance to microbial degradation would indicate insignificant if any change in quantitation.


HOLDING TIMES, PRESERVATION, AND SAMPLE STORAGE

Holding Times

Extractions and analyses were performed within the recommended holding time criteria.

Preservation and Sample Storage

The samples were preserved and stored appropriately.

BLANKS

Method Blanks

Laboratory method blank analyses were performed at the required frequencies. Zinc was reported in the method blanks for both total and dissolved metals analyses, but at levels three orders of magnitude below sample concentrations. No degradation of data quality is suspected. No other target analytes were detected above the reporting limits (RLs) in method blanks.

Trip Blanks

Trip blanks were not required for this sampling event.

Field Blanks

Field blanks were not required for this sampling event.

Equipment Rinsate Blanks

Equipment rinsate blanks were not required for this sampling event, as all samples were collected using single-use equipment.

SURROGATE RECOVERY RESULTS

The samples were spiked with surrogate compounds to evaluate laboratory performance on individual samples.

Four of twelve Base/Neutrals and Acids surrogate recoveries exceeded upper control limits. One exceedance was attributed to matrix interference and two were still less than full recovery. All remaining surrogate recoveries were within acceptance limits.

MATRIX SPIKE/MATRIX SPIKE DUPLICATE RESULTS

Matrix spike/matrix spike duplicates (MS/MSD) are field samples spiked with target analytes to provide information on laboratory precision and accuracy specific to the sample matrix. The MS/MSD samples were extracted and analyzed at the required frequency. All recoveries were within acceptance limits for percent recovery and relative percent differences (RPDs).


LABORATORY CONTROL SAMPLE/LABORATORY CONTROL

SAMPLE DUPLICATE RESULTS

Laboratory control sample/laboratory control sample duplicates (LCS/LCSD) are laboratory prepared samples spiked with target analytes to provide information on laboratory precision and accuracy independent of possible field sample matrix interference. LCS extractions and analyses were performed at the required frequency. Recoveries for three Method 625 LCS/LCSD analytes and one additional LCSD analyte were marginally above the upper limits but still below 100%. Continuing calibration verification standards (CCVs) met criteria and no degradation of data quality is suspected.

RPD for one Method 625 LCS/LCSD analyte pair exceeded the RPD limit by less than 6%.

All other LCS/LCSD analytes were within acceptance limits for percent recovery and RPD.

LABORATORY DUPLICATE RESULTS

A laboratory duplicate is a sample that is split into subsamples at the lab. Each subsample is then analyzed and the results compared to test the precision of the laboratory measurements. The laboratory duplicate for total suspended solids exceeded the RPD limit. The laboratory assigned an RF qualifier to indicate a duplicate failure due to the result being at or near the method reporting limit. No degradation of data quality is suspected.

FIELD DUPLICATE RESULTS

Field duplicates were not required for this sampling event.

REPORTING LIMITS

SA, NRC, and ARI used routine reporting limits for non-detect results, with the exception of samples requiring dilutions because of high analyte concentrations and/or matrix interferences.

DATA PACKAGE

The data package was reviewed for transcription errors, omissions, and anomalies. None were found.

DATA FLAGS

B Analyte detected in the associated method blank. BA BOD Alternative Calculation: The initial results performed by Standard Methods did not fall within parameters of the

Standard Methods calculation. An alternate approved calculation was performed using the HACH method and the value reported is an estimated concentration.

C Sample(s) does not meet NELAC/ORELAP sample acceptance criteria. See Case Narrative. C1 Sample(s) does not meet NELAC/ORELAP sample acceptance criteria for temperature. CF Results confirmed by re-analysis. CU Cleanup performed as specified by method. D1 The diesel elution pattern for the sample is not typical. D2 The sample appears to be a heavier hydrocarbon range than diesel. D3 The sample appears to be a lighter hydrocarbon range than diesel. D4 Detected hydrocarbons do not have pattern and range consistent with typical petroleum products and may be due to

biogenic interference. D5 Detected hydrocarbons in the diesel range appear to be weathered diesel. E Estimated value. ER Elevated reporting limit due to matrix. Report limits (MDLs, MRLs & PQLs) are adjusted based on variations in

sample preparation amounts, analytical dilutions, and percent solids, where applicable. FC Fecal Coliforms: Sample(s) received past 40 CFR Part 136 specified holding time. Results reported as estimated

values. G1 The gasoline elution pattern for the sample is not typical. G2 The sample appears to be a heavier hydrocarbon range than gasoline. G3 The sample appears to be a lighter hydrocarbon range than gasoline. G4 Detected hydrocarbons in the gasoline range appear to be weathered gasoline. HP Sample re-analysis performed outside of method specified holding time. HR Sample received outside of method specified holding time. HS Sample analyzed for volatile organics contained headspace. HT At the client’s request, the sample was analyzed outside of method specified holding time. H Analysis performed outside of method specified holding time. J Analyte detected below the Minimum Reporting Limit (MRL) and above the Method Detection Limit (MDL). The J

flag result is an estimated value and the user should be aware that this data is of limited reliability. MI Surrogate or Matrix Spike recovery is out of control limits due to matrix interference. Sample results may be biased. N See Case Narrative on page 2 of report. Q Closing continuing calibration verification (CCV) or laboratory control sample (LCS) exceeded high recovery limits,

but associated samples are non-detect and the sample results are not affected. Data meets EPA/NELAC requirements. R Relative percent difference (RPD) is outside of the accepted recovery limits. R1 Relative percent difference (RPD) is outside of the accepted recovery limits. However, analyses are not controlled on

RPD values for sample concentrations that are less than the reporting limit. R3 The relative percent difference (RPD) and/or percent recovery for the duplicate (DUP) or matrix spike (MS)/matrix

spike duplicate (MSD) cannot be accurately calculated due to the concentration of analyte already present in the sample.

R4 Duplicate analysis failed due to result being at or near method reporting limit. S Surrogate and/or matrix spike recovery is outside of the accepted recovery limits. Sample results may be biased. S1 Surrogate or matrix spike recovery is outside of control limits due to dilution necessary for analysis. SC Sub-contracted to another laboratory for analysis. T Toxicity Characteristic Leaching Procedure – Sample submitted contained < 0.5% solids. If the waste contains <0.5%

dry solids, the liquid portion of the waste, after filtration, is defined as the TCLP extract. # Value exceeds regulatory level for TCLP contaminant. X1 The motor oil elution pattern for the sample is not typical. X2 The sample appears to be a heavier hydrocarbon range than motor oil. X3 The sample appears to be a lighter hydrocarbon range than motor oil. * Value exceeds Maximum Contaminant Level or is outside the acceptable range.

RE: Projects: 141017 4ll4l0l75lf 410089ARI Job No: ZK82

Dear Nikki:

Please find enclosed copies of the original chain of custody records and the final results forthe samples from the project referenced bbove. Analytical Resources, Inc. (ARI) originallyreceived these samples on October 17 and October 24, 2014. The samples were re-analyzed,for TBT as requested.

All samples were initially extracted on lllI9l14. The extract for sample 1410089-001 waslost before its extraction was complete. This sample was extracted a third time onIl/2ll14. The re-extraction proceeded without incident of note. The result for the lll2lll4extraction only has been submiued for this sample.

There were no fuither problems with these analyses.

A copy of these reports and all supporting data will remain on file with ARI. Please feelfree to contact me if you have any questions or require any additional information.

Respectfully,

ANALYTICAL RESOURCES. INC.I
