SUBJECT: First and Second Quarters 2011 Stormwater Assessment Workplan Status 

Update; 3000 NW St. Helens Rd., Portland, Oregon

DATE: October 7, 2011

I . INTRODUCTION

On behalf of IMACC Corporation, Strategic Engineering & Science, Inc. (SES) has 

prepared this Technical Memorandum summarizing recent field work conducted at the 

Container Management Services, LLC (CMS) facility, located at 3000 NW St. Helens 

Road, Portland, Oregon (Site). 

Field activities conducted during the First and Second Quarters of 2011 were performed 

in accordance with the approved Stormwater Assessment Workplan dated January 30, 

2009 (“Stormwater Assessment Workplan”). 

The following were 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 submitted 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 QUARTER 2011

On April 4 and June 1, 2011, 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).

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.

- Visual sample observations (sheen, odor, e.g.).

- Field temperature, pH, and conductivity measurements.

Following completion of the field observations, grab stormwater samples were collected 

using the following procedures:

- The sample container was held with its opening facing upstream.

- Samples were collected where the water had moderate flow.

- Samples 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 just 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 were 

placed in a cooler with ice.

Site stormwater samples were submitted to Test America, a State-certified laboratory, 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 organic compounds (VOCs) 

- Semi-volatile organic compounds (SVOCs) 

- Polychlorinated biphenyls (PCBs) 

- Polynuclear aromatic compounds (PAHs) 

- Organochlorine Pesticides 

- Total Suspended Solids

- Total Organic Carbon

 

1 Samples collected during the first stormwater sampling 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.

Data collected during stormwater assessment activities 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 through Table 1H

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

According to the hydrographs, the second sampling event was conducted during a storm 

which met the following DEQ criteria for a qualifying 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 collected 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, the third storm event did not meet the requirement for 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.

Review 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.
