Chance to Comment On…..

Proposed No Further Action Decision for the Pacific Car Crushing Site

Publication:

The Oregonian and Secretary of State’s Bulletin

Publishing Date:

November

1, 2004

Comments Due:

November 30, 2004

Project Location:

The site is located at 9635 North Columbia Boulevard in Portland, Oregon.

Proposal:

Pursuant to Oregon Revised Statute, ORS 465.320, and Oregon Administrative Rules, OAR 340-122-

100, the Department of Environmental Quality (DEQ) invites public comment on its proposal for a “No Further

Action” (NFA) determination proposed for the Pacific Car Crushing Site, removal of the site from the Confirmed

Release and Inventory Lists, and issuance of a Certificate of Completion for the existing Consent Order.

Highlights:

The site has been used as an auto recycling facility since the 1970’s and has been owned by North West

Recycling Incorporated since 1980.

Operations at the site include auto receiving, a “U-Pull-It” salvaging yard, auto

dismantling and crushing, and repair and maintenance of heavy equipment and trucks.

All auto fluids, batteries and

tires are collected and stored on site in separate containers or areas for recycling, resale, or disposal.

The site is

located near the Columbia Slough, with Union Pacific Railroad right-of-way between the site and the Slough.

Site storm water is managed under the National Pollution Discharge Elimination System and a General Permit 1200-

COLS permit.

Storm water from the site is directed by a series of culverts and by sheet flow to a storm water

retention pond.

Storm water from the auto crushing building is directed to an oil and water separator.

The retention

pond overflows during times of high rainfall and the storm water infiltrates into the ground adjacent to the pond.

An investigation has been conducted of soil, retention pond sediment and overflow water, surface water, and

groundwater at the site.

The purpose of the investigation was to determine whether a release of hazardous chemicals

had occurred, and whether a completed pathway exists for site-related chemicals to reach the adjacent Columbia

Slough. Groundwater in a perched zone leaks downward to the shallow groundwater, and may also discharge to the

Slough in the easternmost portion of the site immediately adjacent to the Slough. Shallow groundwater beneath the

site flows to the southeast, and eventually discharges to the Slough at a distance from the site.

Site investigation

results indicate low levels of contaminants present in soil, pond sediment and water, and groundwater that include

petroleum hydrocarbons, polynuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), volatile

organic chemicals (VOCs) and metals.

Petroleum hydrocarbons were detected in highest concentrations in soil in

the car crushing area.

PAHs were detected at low concentrations in soil across the site, in pond sediment and water,

and at very low concentrations in groundwater.

PCBs at low concentrations were detected in pond sediment.

Low

concentrations of VOCs were detected in soil and groundwater.

Metals, mainly arsenic, lead, barium and selenium,

were detected in shallow perched and water table groundwater at levels that exceed SLVs but did not exceed

expected background concentrations, were infrequently detected, or likely from off site sources.

The property owner has conducted soil and sediment removal actions.

Between 1995 and 2001 some 810 tons of

petroleum contaminated soil has been removed from the car crushing area and replaced with clean gravel fill. The

owner has instituted improved management practices and also paved the car crushing building area to reduce or

eliminate releases of auto fluids during crushing operations. The on site storm water retention pond was

reconstructed 2001 and about 262 tons of PAH and PCB contaminated pond sediment was excavated and disposed.

In June 2003, about 950 tons of PAH contaminated soil near the office building was excavated to a site-specific risk-

based cleanup concentration and the soil disposed.

A risk assessment was performed to evaluate risks to potential human and ecological receptors due to exposure to

surface and subsurface soil, groundwater, and sediments, and included completion of a Level I scoping assessment.

The site is an active industrial property and does not support ecological habitat and no further ecological risk

assessment was conducted for soil.

Soil exposure scenarios included incidental ingestion, dermal contact, and

inhalation of volatiles or dust by workers, trench workers, and trespassers.

Risk assessment results indicate that risk

to humans for exposure to contaminants in soil at the site is below acceptable risk levels established by DEQ.

Perched groundwater was evaluated for exposure of workers to indoor/outdoor air, groundwater during trenching,

and exposure of Slough recreational users to site chemicals discharged to the Slough via groundwater, and to aquatic

receptors in the Slough.

The results of the risk assessment indicate that the risk to humans and ecological receptors

for exposure to groundwater and surface water are below acceptable levels established by DEQ.

DEQ has concluded that no further actions are warranted for this site because risk-based criteria for human and

ecological receptors have not been exceeded.

Since no further actions would be required for the site DEQ proposes

to remove the site from the Confirmed Release and Inventory Lists.

All work required under the existing Consent

Order has been completed and, with no further action required for the site, a Certificate of Completion would be

issued and the Consent Order terminated.

DEQ must receive written comments by 5:00 p.m. on November 30, 2004.

This

notice will also be published in the local newspaper The Oregonian.

DEQ will hold a public meeting to receive verbal comments if 10 or more persons, or a group with membership of

10 or more requests such a meeting.

Interest in holding a public meeting must be submitted in writing to DEQ.

If a

public meeting is held, a separate public notice announcing the date, time, and location of any public meeting would

be published in this publication.

DEQ is committed to accommodating people with disabilities at our hearings. Please notify DEQ of any special

physical or language accommodations or if you need information in large print, Braille or another format. To make

these arrangements, contact DEQ Communications and Outreach at [phone] or toll free in Oregon at

The Next Step: DEQ

will consider all public comments received by the November 30, 2004 deadline.

In the

absence of comments, DEQ will issue the No Further Action, remove the site from the Confirmed Release and

Inventory Lists, and issue a Certificate of Completion for the Consent Order.
