Dear Ms. Goldstein:

On behalf of BP West Coast Products, LLC. (BP), ARCADIS U.S., Inc. (ARCADIS) is

pleased to submit this Quarterly Groundwater Monitoring Report, Second Quarter

2012 for the above referenced facility (the “Site”). The Site currently operates as the

Lynnwood Convention Center located at 3711 196th Street, Lynnwood, Washington.

The next groundwater monitoring event is scheduled for the third quarter of 2012.

Should you have any questions in regards to the aforementioned report or if

ARCADIS can be of further assistance, please contact Kevin Freeman at

509.535.7225.

Sincerely,

ARCADIS U.S. Inc

Work Performed this Quarterly Reporting Period (Second Quarter 2012):

1. On May 17, and May 18, 2012, ARCADIS U.S., Inc. (ARCADIS) conducted quarterly groundwater

monitoring activities at the Site. During this event, monitoring wells MW-7a, MW-7b, MW-9 and MW-13

were gauged and MW-6, MW-7c, MW-8, MW-10, MW-11, MW-12, MW-14, MW-15, MW-16, MW-

17,and MW-18 were gauged and sampled using one well volume purge methodology with disposable

bailers (field data sheets are included as Attachment A). Groundwater samples were analyzed for

gasoline range organics (GRO) by Northwest Method TPH-G Extended (NWTPH-Gx) benzene,

toluene, ethylbenzene, total xylenes (BTEX), Methyl tert-butyl ether (MTBE) by EPA Method 8260B,

and total lead by EPA 200.7. Current and historical groundwater gauging data and current and

historical groundwater analytical data are summarized in Table 1. The laboratory analytical report and

chain-of-custody information for the sampling event are included as Attachment B. Approximately 35

gallons of purge water was generated during groundwater sampling activities. The water was

consolidated in a drum on site pending analysis.

Work Proposed for Next Quarterly Reporting Period (Third Quarter 2012):

1. Conduct third 2012 quarterly groundwater monitoring event

2. Submit the Quarterly Groundwater Monitoring Report, third Quarter 2012 to Ecology

Quarterly Groundwater

Monitoring Report,

Second Quarter 2012

Former ARCO Facility No. 00862 August 15, 2012

Discussion:

During the second quarter of 2012, groundwater conditions at the Site remained generally consistent with

previous sampling events. Depths to groundwater during this sampling event ranged between 7.58 and 35.19

feet below top of well casing (btoc) in monitoring wells MW-18 and MW-17, respectively. Groundwater gauging

data is presented in Table 1.

Groundwater samples were collected from 11 monitoring wells during this sampling event. Concentrations of

GRO above MTCA Level A Cleanup Levels (CULs) were detected in groundwater samples collected from

monitoring wells MW-7c (2,410 μg/L), MW-11 (15,600 μg/L), and MW-12 (8,610 μg/L). Benzene was detected

above CULs in the samples collected from monitoring wells MW-7c (17.8 μg/L), MW-11 (18.7 μg/L), and MW-12

(2,310 μg/L). Toluene was not detected above MTCA A CULs for groundwater in the samples collected.

Ethylbenzene was detected above CULs in well MW-12 (1,110 μg/L). Total xylenes, total lead and MTBE were

not detected above MTCA A CULs for groundwater in the samples collected.

Groundwater Monitoring Program:

Groundwater monitoring wells that were gauged and sampled during this event will be gauged and sampled on

a quarterly basis. Groundwater monitoring wells were sampled utilizing one well volume purge sampling

techniques. ARCADIS anticipates using similar methodologies during the next monitoring event.

QUALIFIERS

Pace Project No.:

Project:

2512207

WA-0862

DEFINITIONS

DF - Dilution Factor, if reported, represents the factor applied to the reported data due to changes in sample preparation, dilution ofthe sample aliquot, or moisture content.

ND - Not Detected at or above adjusted reporting limit.

J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.

MDL - Adjusted Method Detection Limit.

PRL - Pace Reporting Limit.

RL - Reporting Limit.

S - Surrogate

1,2-Diphenylhydrazine (8270 listed analyte) decomposes to Azobenzene.

Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.

LCS(D) - Laboratory Control Sample (Duplicate)

MS(D) - Matrix Spike (Duplicate)

DUP - Sample Duplicate

RPD - Relative Percent Difference

NC - Not Calculable.

SG - Silica Gel Clean-Up

N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported foreach analyte is a combined concentration.

Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

QUALIFIERS

Pace Project No.:

Project:

2512221

WA-0862

DEFINITIONS

DF - Dilution Factor, if reported, represents the factor applied to the reported data due to changes in sample preparation, dilution ofthe sample aliquot, or moisture content.

ND - Not Detected at or above adjusted reporting limit.

J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.

MDL - Adjusted Method Detection Limit.

PRL - Pace Reporting Limit.

RL - Reporting Limit.

S - Surrogate

1,2-Diphenylhydrazine (8270 listed analyte) decomposes to Azobenzene.

Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.

LCS(D) - Laboratory Control Sample (Duplicate)

MS(D) - Matrix Spike (Duplicate)

DUP - Sample Duplicate

RPD - Relative Percent Difference

NC - Not Calculable.

SG - Silica Gel Clean-Up

N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported foreach analyte is a combined concentration.

Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

TNI - The NELAC Institute.

LABORATORIES

Pace Analytical Services - SeattlePASI-S

ANALYTE QUALIFIERS

The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.D6

Analyte concentration exceeded the calibration range. The reported result is estimated.E

Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
