Title
Resolution to Approve the Purchase of an Odor Control Chemical from D3W Industries, Inc. for the Wastewater Treatment Plant ($100,650.00 - estimated)
Memorandum
Your approval is requested to authorize the purchase of up to 1,650 gallons of an odor control chemical from D3W Industries, Inc. (D3W) for the City's Wastewater Treatment Plant (WWTP) at the unit price of $20,130.00 per 330-gallon tote ($61.00 per gallon) and a total estimated cost of $100,650.00 for FY 17.
During the winter season, the WWTP centrifuges liquid biosolids to reduce the moisture content and produce a cake that is disposed in a landfill. Previously, the WWTP added lime dust to the centrifuged cake to reduce odors to a level that made the cake acceptable to the landfill. However, during truck loading activities, the lime dust released significant amounts of ammonia that caused strong odors at the WWTP and migrated to areas surrounding the plant. As a result, the Michigan Department of Environmental Quality (MDEQ) received odor complaints and informed the City that it was not in compliance with the terms of its air quality permit.
Through various field tests, WWTP staff determined that a chemical called Planet Breeze from D3W is most effective for reducing odor complaints both locally and at the landfill. Consequently, Planet Breeze was used during the last two winter landfill seasons. Based on these successful results, and to avoid violations of the MDEQ air quality permit that could lead to citations, fines or other regulatory actions, your approval is requested for the purchase of Planet Breeze for the upcoming winter landfill season. It is further recommended that the purchase of Planet Breeze from D3W be approved for a one-year period with two one-year renewals by mutual agreement. D3W is the sole manufacturer and distributor of this particular product.
