RE: UNDERGROUND STORAGE TANK INSTALLATION
NORTH LEMAY.PLAZA
FORT COLLINS, COLORADO
Dear Mr. Sawyer:
The North Lemay Plaza is a P.U.D. that has been submitted to the City for final
review.
A part of this P.U.D. is.a convenience center which will have fuel filling
center. The City has requested that you review the outlined specifications
for tank installation for this property. The main concern appears to be with
potential groundwater contamination from tank leakage.
As you are aware, State and Federal regulations govern the installation of
these types of installations.
It is the Intent of the Developer and the Tenant/Operator to follow all
applicable regulations for fuel storage tank installations. It will be
the Tenant, P.D.Q.'s responsibility for the installation of these facl-
ities and for on -going maintenance.
Currently a 'soils' investigation has been performed by Empire Labs of
Fort Collihls for the site outlining soil and groundwater conditions that
exist on site. These recommendations will be followed in preparing site
and installing the tanks.
I am including along with the outline specifications a copy of the soils' re-
port and a site plan showing.the tank locations. As you will note, the tanks
are placed on a virtually level portion .of the site more than 65 feet from the
irrigation canal to the South of the site which is noted as potentially unstable
ground in the §oils' f8 port.
If ybd kavG 66y questions; please give me a call.
