RESOLUTION AUTHORIZING PURCHASE OF GRANULAR ACTIVATED CARBON
FROM CALGON CARBON CORPORATION AS A SOLE SOURCE
IPWHEREAS, 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 know 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
Iactivated 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 $44,000.00 for the purchase of 40,000 pounds of Filtrasorb 300.
