FROM: Steve Kemnitz, R.E.A. I Mohammad Bazargani, P.E. Strategic Engineering & Science, Inc.

SUBJECT: First and Second Quarter s 2011 Stormwater Assessment Workplan Status Update ; 3000 NW St. Helens Rd., Portland, Oregon

DATE: October 7 , 201 1

I . INTRODUCTION 

## On behalf of IMACC Corporation, Strategic Engineering & Science, Inc. (SES) has prepar ed this Technical Memorandum summarizing recent field work conducted at the Container Management Servic es, LL C (CMS) facility, located at 3000 NW St. Helens Road, Portland, Oregon (Site).

Field activities conducted during th e F irst and Second Quarter s of 201 1 were performed in accordance with the approved Stormwater Assessment Workplan dated January 30, 2009 ( “ Stormwater Assessment Workplan ”)

. The following we re the objectives of the field activities performed at the Site:

**•** Perform and document stormwater sampling events.

II. FIRST QUARTER 2011 

## During the First Quarter 2011, SES and IMACC completed and submitt ed the February 16, 2011 Fourth Quarter 2010 Stormwater Assessment Workplan Status Update; 3000 NW St. Helens Rd., Portland, Oregon

. No additional stormwater related activities were conducted at the Site during the First Quarter 2011.

III. SECOND QUARTE R 2011


## On April 4 and June 1 , 201 1 , SES conducted the second and third of four stormwater sampling events. As contemplated in the Stormwater Assessment Workplan , stormwater samples were collected from 2 of the 13 Site catch basins (SW

- 8 and SW

- 12) and from two on

- site stormwater access vaults (SW

- 2 and SW

- 3).

## Mr. Jim Orr October 7 , 201 1 Page 2 of 4 Prior to the collection of grab stormwater samples, the following observations were noted on a stormwater Sample form:

- Description of weather.

- Time rainfall commenced.

- Time of first observed runoff.

- Vi sual sample observations (sheen, odor, e.g.)

.

- Field t emperature, pH, and conductivity measurements. Following completion of the field observations, grab stormwater samples were collected using the following procedures:

- T he sample container was held with i ts opening facing upstream.

- Sample s w ere collected where the water had moderate flow.

- Sample s were collected from the central portion of the stormwater flow. Stormwater samples from access vault SW

- 3 were collected from the central portion of the flow jus t prior to its exit through the 42

- inch stormwater pipeline. This was to ensure that the sample included influent from SW

- 6, SW

- 5, and the southern portion of the Site. After the samples were labeled and documented in the chain of custody record, they wer e placed in a cooler with ice.

S ite stormwater samples were submitted to Test America , a State

- certified labora tory, for analysis. The samples were properly preserved and transported to the laboratory under appropriate chain

- of

- custody protocol. 1



## The laboratory analyzed the stormwater samples for the following constituents:

- Total metals

- Total petroleum hydrocarbons as gasoline (NWTPH

- G)

- Total petroleum hydrocarbons as diesel (NWTPH

- D)

- Residual range petroleum hydrocarbons (NWTPH

- RRO)

- Volatile orga nic compounds (VOCs)

- Semi

- volatile organic compounds (SVOCs)

- Polychlorinated biphenyls (PCBs)

- Polynuclear aromatic compounds (PAHs)

- Organochlorine Pesticides

- Total Suspended Solids

- Total Organic Carbon

### Samples collected during the first stormwater s ampling event were sent to Columbia Analytical for analysis. Due to problems with the detection levels reporting, however, SES determined a change in laboratories was needed.

## Mr. Jim Orr October 7 , 201 1 Page 3 of 4 Data collected during s tormwater a ssessment acti vities are evaluated by comparing constituent concentrations to the Joint Source Control Strategy Screening Level Values (JSCS SLVs) for Stormwater, Groundwater, and Surface Water

. A summary of stormwater analytical results are presented in Table 1A thro ugh Table 1H in Attachment A

. A hydrograph of each sampling event is included in Attachment B

.

According to the hydrograph s , the second sampling event was conducted during a storm which met the following DEQ criteria for a qua lifying storm event: Stormwater Sampling Round 2:

**•** Antecedent dry period of at least 24 hours (as defined by <0.1 inch over the previous 24 hours)

**•** Minimum rainfall volume of >0.2

- inches

**•** Duration of storm event at least 3 hours During the second sample event, stormwater samples were col lected within five hours of the start of discharge. According to the Stormwater Assessment Workplan , “stormwater samples should be collected within three hours of the start of discharge, when practical.” Due to the 4 a.m. start of the storm event, it was not practical for SES or IMACC personnel to sample within the suggested 3 hour timeframe.

According to the third sampling event hydrograph, sampling was conducted during a storm which met two of the three DEQ criteria for a qualifying storm event: Stormwater Sampling Round 3 :

**•** Minimum rainfall volume of >0.2

- inches

**•** Duration of storm event at least 3 hours Additionally, stormwater samples were collected within 3 hours of the start of discharge. However, t he third storm event did not meet the requirement fo r an antecedent dry period of at least 24 hours. Sampling was conducted on June 1, 2011 between the hours of 9 a.m. to 12 p.m. According to the rainfall data from that time period , approximately 0.08 inches of rainfall fell between the hours of 6 a.m. and 9 a.m. on May 31, 2011 and approximately 0.07 inches of rainfall fell between the hours of 12 a.m. and 5 a .m. on June 1, 2011. The results represent conditions similar to continuous stormwater discharge from the site

.

## Mr. Jim Orr October 7 , 201 1 Page 4 of 4

Rev iew of laboratory results show that some detection limits exceeded the listed JSCS SLVs criteria. However, the laboratory has indicated that obtaining detection limits less than the conservative JSCS SLVs may not be achievable in some analyses. Laboratory Detection Limits:
