The 401 Central Avenue LUST Site was admitted to the Voluntary Cleanup

Program on June 30, 2015. The Voluntary Cleanup Program documents related to the

Site include:

Monitoring Well. October 11, 2018.

7. Ecology. Opinion Letter. May 14, 2019.

As stated in the 2019 Opinion letter, the chemicals-of-concern at the Site are

defined as gasoline-range total petroleum hydrocarbons (TPH-G), and benzene, toluene,

ethylbenzene, and xylenes (BTEX) in soil. The Site is defined as the soil impacted by the

release of TPH-G and BTEX from the former gasoline underground storage tanks (USTs)

which were closed and removed from the ground in 2013.

1.1 GENERAL SITE INFORMATION

The Site is located at 401 Central Avenue in Bellingham, Washington (Parcel

380330114260 and Central Avenue). The Site is in the southwest quarter of the northwest

quarter of Section 30 in township 38 North, Range 3 East. The Site is situated

approximately 0.15 miles east of the mouth of Whatcom Creek and Bellingham Bay, and

approximately 0.85 miles west of I-5. The Site is zoned as Commercial by the City of

Bellingham. The Site is bordered on the north, east, and south by commercial properties.



2 6/16/2020

It is bordered on the west by Maritime Heritage Park, a former landfill. The Site location

is shown on Figure 1.

The Site has been assigned the Facility Site ID# 10851, Cleanup Site ID# 12378,

and VCP# NW2987. Contact information for the Ecology site manager, project consultant

and property owner is included below.

1.2 PURPOSE OF CURRENT DOCUMENT

This document has been prepared for two reasons:

1) To provide Ecology with soil and groundwater data collected at the Site in 2019-

2020; and

2) To request an Opinion on the likelihood of obtaining a Property No Further

Action determination for the portion of the 401 Central Avenue LUST Site contained

within Parcel 380330114260.

2.0 2019 GROUNDWATER MONITORING WELL INSTALLATION

Two groundwater monitoring wells have been installed at the Site. MW-1 was

installed on November 30, 2016. MW-2 was installed on June 17, 2019. The well locations

are shown on Figure 2. The Bore Logs are included in Appendix A and the Well Logs are

included in Appendix B.

2.1 2019 SOIL DATA

Soil samples were collected during the installation of groundwater monitoring well

MW-2. The soil sample descriptions are included in Table 1. The soil samples were

analyzed for Volatile range TPH, Diesel and Oil range TPH, BTEX, MTBE, EDB, EDC,

Naphthalenes, cPAHs, and Lead.

No petroleum constituents were detected above the laboratory detection limits.

Lead was detected at background levels. The soil analytical results are summarized in

Tables 2-4. The laboratory analytical data report is included in Appendix C.

2.2 GROUNDWATER DATA

Groundwater data collected from monitoring wells MW-1 and MW-2 are

summarized in Table 5. The laboratory analytical data reports are included in Appendix

C.

MW-1 has had intermittent detections of benzene and EDC at concentrations

which exceeded the MTCA Method A target cleanup levels. The benzene and EDC

concentrations met the MTCA Method A target cleanup levels in the most recent sampling

event conducted in April 2020.

MW-2 had one detection of diesel range TPH in 2019, however the sample was re-

analyzed with silica gel cleanup and the concentration was reduced to non-detect. EDC

has been detected at concentrations above the MTCA Method A target cleanup level in all

sampling events.

3.0 PROPOSED GROUNDWATER MONITORING WELL INSTALLATION

Johnston-Peach LLC is interested in obtaining a Property No Further Action

determination for the portion of the 401 Central Avenue LUST Site contained within

Parcel 380330114260. In order to investigate the groundwater quality on Parcel

380330114260, a groundwater monitoring well will be installed on the parcel at the

location shown on Figure 2.

3.1 WELL INSTALLATION

One additional groundwater monitoring well will be installed at the site. The

proposed well will be identified as MW-3 (Figure 2). The well will be installed using a

hollow-stem auger drill rig. A public underground utility locate will be conducted, and

the boring location will be cleared using an air-knife to a depth of five feet prior to drilling.

The well will be installed to a total depth of 30 feet (or first indication of bedrock). Soil

cuttings will be temporarily stored onsite in a 55-gallon drum for eventual offsite disposal.

3.2 SOIL SAMPLING

Soil samples collected from the boring will be field screened using a

photoionization detector (PID) and by conducting sheen tests. Soil samples will be

collected from the boring via Method 5035a. The following laboratory methods will be

used to analyze the soil samples:

NWTPH-Dx: Diesel and oil range total petroleum hydrocarbons (TPH)

NWTPH-Gx: Gasoline (volatile) range TPH

EPA Method 8260: Benzene, toluene, ethylbenzene, and total xylenes (BTEX

constituents), Methyl tert-butyl ether (MTBE), Ethylene dichloride (EDC), and

Ethylene dibromide (EDB)

EPA Method 8270 SIM: Naphthalenes and Carcinogenic Polycyclic Aromatic

Hydrocarbons (cPAH)

EPA Method 6020: Lead (Pb)



5 6/16/2020

The groundwater monitoring well will be purged and developed using a disposable

bailer. The purged water will be temporarily stored onsite in a 55-gallon drum for eventual

offsite disposal.

3.3 GROUNDWATER SAMPLING

After the new well has been developed, groundwater samples will be collected from

both the new and existing wells using a low-flow sampling technique. One sampling event

is accounted for in this proposal. The following laboratory methods will be used to analyze

the groundwater samples:

NWTPH-Dx: Diesel and oil range TPH

NWTPH-Gx: Gasoline (volatile) range TPH

EPA Method 8260: BTEX, MTBE, EDC, and EDB

EPA Method 8270 SIM: Naphthalenes and cPAHs

EPA Method 200.8: Dissolved Lead



6 6/16/2020

4.0 REQUEST FOR OPINION

We request Ecology’s opinion on the following issues:

1) Is the location, installation, and sampling methodology of the proposed

groundwater monitoring well shown on Figure 2 sufficient to determine if the

groundwater on Parcel 380330114260 has been impacted by the release from

the UST?

2) If the soil and groundwater data collected during this investigation meet the

applicable MTCA Method A cleanup standards, will the portion of the 401

Central Avenue LUST Site contained within Parcel 380330114260 be

considered remediated, and will Ecology issue a Property No Further Action

Likely determination?

Limitations

LIMITATIONS

No site investigation can wholly eliminate uncertainty regarding the potential for

contamination in connection with a property. Documentation of the soil remediation by

Whatcom Environmental Services is intended to reduce, but not eliminate, uncertainty

regarding the potential for environmental contamination in connection with the subject

property.

The interpretation of subsurface soil and groundwater conditions is based on field

observations and chemical analytical data collected from relatively widely spaced

sampling locations at the site. It is possible that contamination exists beneath portions

of the site that were not explored, sampled, or analyzed. No warranty, express or implied,

is given regarding the presence of hidden or unidentified sources of contamination of the

subject property. In addition, no warranty, express or implied, is given regarding

geotechnical or geologic hazards.

This environmental report is based on conditions that existed at the time the

investigation was performed and samples collected. The findings and conclusions of this

report may be affected by the passage of time, by manmade events such as construction

on or adjacent to the site, or by natural events such as floods, earthquakes, ground

instability, or groundwater fluctuations.

Within the limitations of scope, schedule, and budget, our services have been

executed in accordance with generally accepted environmental practices in this area at

the time this report was prepared. No warranty or other conditions, express or implied,

should be understood.

This report has been prepared for use by Johnston-Peach LLC. Whatcom

Environmental prepares a report for the client's exclusive use for a particular project and
