End in sight for cleanup of underground gasoline contamination in Yorba Linda at Imperial Hghwy
Finally
– more than 15 years after Yorba Linda acquired land formerly
occupied by a gasoline station on Imperial Highway just west of the
library – an end is in sight for remediation of contamination
caused by longtime leakage from the station's underground storage
tanks.
A
60-day public review period for a “case closure” document ended
May 11, and the Orange County Health Care Agency is expected to issue
a notice authorizing the abandonment of 17 wells that were monitoring
contamination from the 12,872-square-foot site.
The
final step will be a “no further action needed” letter issued by
the health care agency, “upon which the project will be deemed
complete and the site eligible for use or sale,” the City Council
was told in a May 19 report prepared by Assistant City Engineer Rick
Yee.
The
letter is needed before escrow can close on a sale of the former
station site and library land to In-N-Out Burgers. The restaurant
entered into a purchase agreement with the city in 2018, with the
agreement amended at a March 17 council meeting to clarify several
matters.
The
city will assume liability for any additional remediation “that may
become evident after the closing of escrow, construction of the
project and opening of the restaurant,” according to a report to
the council from Pam Stoker, the city's economic development manager,
in March.
Stoker
stated that the amendment clarifies the city's demolition and site
preparation duties, including locating and staking utilities,
abandoning and capping existing utilities at the prop-erty line and
assisting in the quitclaim and release of certain easements on the
parcel.
After
the city purchased the property in 2004 to facilitate Imperial
Highway widening, the Superior Court required the city to eliminate
underground contamination. The removal of floating gasoline from the
groundwater was completed in 2011, with the next years spent removing
the dissolved gasoline mixed with groundwater.
The
site now meets the technical requirements of the county health care
agency and the guidelines set by the State Water Resources Control
Board by the city-hired remediation contractor, Stantec Consulting
Services, with some 17,500 pounds of contaminate removed.
Cost
will total close to $1.2 million by the time the fencing with the
green canvas security screen is removed, with the Orange County
Transportation Agency and the State Under-ground Storage Tank Program
picking up most of the expense.
The
city's portion is expected to be $204,523. A $66,934 credit will be
returned to the city.
