QWEST COMMUNICATIONS W00161
1305 Washington Way, Longview, WA 98632

PUBLIC COMMENT PERIOD JUNE 06, 2019-JULY 07, 2019

SECOND PERIODIC REVIEW

Ecology invites your comments on the draft Second Periodic Review Report for the Qwest Communications site. The first periodic review was in 2014.

Environmental cleanup is complete at the site, and the draft Periodic Review Report shows that the cleanup work remains effective in protecting the health of people and the environment. Ecology may modify the draft report if the public submits new information during the comment period.

After cleanup, concentrations of diesel and oil-range petroleum hydrocarbons remain in soil and groundwater at the site. To prevent possible exposure to that contamination, a restrictive covenant was filed for the site in 2007. The covenant restricts property use and requires that no groundwater can be taken for any use from the property. The owner can not alter, modify, or remove the existing structure without prior written consent from Ecology.

When an environmental covenant exists for a cleanup site, Ecology reviews site conditions about every five years to ensure the long-term effectiveness of the cleanup action.

Ecology inspected the site on March 13, 2019, and investigated current conditions, which continue to eliminate possible exposure to contaminants.

SITE DESCRIPTION

The Qwest Communications site is located at 1305 Washington Way in downtown Longview. The site consists of an office/commercial building with several paved parking areas located along the south side of the property. The Cowlitz River is about 1 mile east of the site.

Leaking underground storage tanks on the southeastern portion of the site caused petroleum contamination of soil and groundwater. 


SITE CLEANUP

In 1992, the property owner removed:

  • Tank 1, a 1,680-gallon diesel fuel and heating oil tank.
  • Tank 2, a 300-gallon heating oil tank.
  • Tank 4, a 6,000-gallon diesel fuel tank.

About 130 cubic yards of petroleum contaminated soil were removed from the area around Tank 1 and 2. Some contaminated soil near Tank 2 could not be removed because it was located close to the building foundation and further excavation would have jeopardized the structural the integrity of the building. About 100 cubic yards of petroleum contaminated soil were excavated from the area around where Tank 4 was located. The pits dug to remove Tanks 1, 2 and 4 were filled with clean soil and paved over with asphalt. 

Tank 3 was a 2,000-gallon diesel fuel storage tank located inside the building. This tank was decommissioned and closed in-place. Clean soil was backfilled around the tank and the area was paved over with asphalt. 

In 2003 to 2011, diesel and oil range petroleum hydrocarbons were below state cleanup levels in groundwater. In 2013 petroleum contamination of groundwater above cleanup levels was found in one monitoring well. 

Groundwater monitoring was increased to quarterly. Two of nine sampling events indicated diesel concentrations were above cleanup levels in one well. If results of continued monitoring show increased diesel or oil-range hydrocarbons in groundwater, then other cleanup actions will be evaluated to address the contamination at the site.

A soil vapor pathway is not a problem at this site because no volatile organic compounds, gasoline, or BTEX (benzene, toluene, ethylbenzene, or xylenes) were found in soil or groundwater.

The owner recorded an environmental covenant for the property in 2007. The covenant prohibits activities that might cause the release of contaminants contained as part of the cleanup.

Ecology held a public comment period for the first periodic review from April 17 to May 19, 2014, and received no comments.
