TRANSMITTAL LETTER FOR BOARD MEETING OF APRIL 23, 2015
COMMITTEE ON MAINTENANCE AND OPERATIONS
Mr. David St. Pierre, Executive Director
Title
Final report on emergency Contract 14-900-01, Rental and Maintenance of an Odor Control System at the Stickney Water Reclamation Plant, to Nu-Recycling Technology, Inc., Account 901-69000-612650, Purchase Order 5001468
Body
Dear Sir:
In June of 2014, several odor complaints were filed with the Stickney Treatment Plant Operators concerning an odor being generated near the corner of Central Avenue and 39th Street. The odor was investigated and found to be sourced from the Westside Plant Imhoff tanks Batteries B & C. Imhoff tank Battery A was removed from service under Contract 04-128-3P to make room for new Westside preliminary tanks. The two remaining Imhoff Batteries, B & C, remained in service. The increased loading on the tanks caused the increased scum build-up which generated the odors.
On June 17, 2014, the Director of Maintenance and Operations declared an operating emergency and issued Emergency Contract 14-900-01 to Nu-Recycling, Inc., in the amount of $50,000.00, for rental, installation and maintenance of an odor control system at the Stickney Water Reclamation Plant. The odor control system was placed in service on June 23, 2014, and has been effective in controlling the point source odors and eliminating further odor complaints. The Imhoff odor control system remains in service and will be maintained via separate purchase order in 2015.
Final completion under Contract 14-900-01 was achieved on December 31, 2014, with a final cost of $36,300.00.
Respectfully submitted, Manju Prakash Sharma, Director of Maintenance and Operations, AQ:SO'C:MAG:JK
