RESOLUTION AUTHORIZING PURCHASE OF GRANULAR ACTIVATED CARBON
FROM CALGON CARBON CORPORATION AS A SOLE SOURCE
WHEREAS, the Director of Public Works has reported to the City Council that
the granular activated carbon filtration system which serves to treat groundwater
affected by the operations of the former Reilly Tar & Chemical Corporation wood
creosoting/preservation facility prior to its discharge to the municipal water
supply has expended its service life, thereby necessitating its replacement; and
WHEREAS, the Director of Public Works has further reported that the
filtration system which utilizes the granular activated carbon as the filter media
was designed and constructed by Calgon Carbon Corporation, based upon the hydraulic
and treatment parameters of a specific carbon known commercially as Filtrasorb 300;
and
WHEREAS, a survey of specific uses of granular activated carbon indicates
that the City of St. Louis Park may be the only supplier of water for public use
that treats water for the removal of polynuclear aromatic hydrocarbons to total
levels less than 175 parts per trillion; and
WHEREAS, present technical expertise relative to the treatment of groundwater
for the removal of polynuclear aromatic hydrocarbons by granular activated carbon
reflects only the limited experience of the City of St. Louis Park, thereby
limiting the City's ability to ascertain the effectiveness of other commercially
provided granular activated carbon to meet its particular needs.
NOW, THEREFORE, BE IT RESOLVED BY THE CITY OF ST. LOUIS PARK that although it
has diligently sought confirmation that there exists a commercially produced
granular activated carbon other than Calgon Carbon Corporation's Filtrasorb 300
which has similar hydraulic and treatment characteristics for the removal of
polynuclear aromatic hydrocarbons from municipal drinking water supplies to low
part per trillion levels, it has not identified an alternate to the Filtrasorb 300.
BE IT FURTHER RESOLVED that due to circumstances beyond the control of the
City, it has been determined that Filtrasorb 300 granular activated carbon,
produced by Calgon Carbon Corporation, is the only filter media which is known to
be capable of meeting the needs of the City at this time, thereby rendering Calgon
Carbon Corporation as a sole source supplier of granular activated carbon.
BE IT FURTHER RESOLVED that the appropriate City representatives are
authorized and directed to enter into a contract with Calgon Carbon Corporation, in
the amount of $46,885.50 for the purchase of 40,000 pounds of Filtrasorb 300.
