Title
Resolution to Approve Bulk Chemical Purchases for the Water and Wastewater Treatment Plants of Sodium Hypochlorite (JCI Jones Chemical - Approximately $107,400.00/year), Hydrofluorosilicic Acid (Alexander Chemical- approximately $26,384.00/year), Pebble Quicklime (Graymont - Approximately $717,500.00/year) and Ferric Chloride (PVS Technologies - Approximately $50,320.00/year) (estimated $901,604.00/year)
Memorandum
Your approval is requested to authorize the purchase of bulk chemicals (sodium hypochlorite, hydrofluorosilicic acid, pebble quicklime, ferric chloride), which are used in treatment processes at the City's Water and Wastewater Treatment Plants (WTP and WWTP).
In 2021, bids were obtained through the Mid-Michigan Drinking Water Consortium Bulk Chemicals Bid. The Consortium was formed in 2014 by mid-Michigan area utilities that soften drinking water with quicklime, to address chemical supply quality, competitive pricing, and residual disposal.
Consortium members include: Lansing Board of Water and Light; City of Battle Creek; City of Jackson; City of Howell; City of Ann Arbor; City of Fenton; East Lansing Meridian Water & Sewer Authority; Plainfield Township; City of Owosso; Marion-Howell-Osceola- Genoa Water Authority; and Tri-County Regional Planning Commission.
Sodium Hypochlorite
The WTP uses sodium hypochlorite to maintain disinfection of drinking water in the distribution system. The estimated cost of this chemical for FY22 is $107,400.00/year for approximately 150,000 gallons.
Sodium Hypochlorite bids were as follows:
1. JCI Jones Chemical, $0.716 per gallon
2. Olin, $0.7395 per gallon
3. Alexander Chemical, $0.8274 per gallon
Hydrofluosilicic Acid
The Center for Disease Control (CDC) has established that 0.7 milligrams per liter (mg/L) of fluoride in drinking water is safe, healthy, and effective for preventing tooth decay. The City's source water contains approximately 0.3 mg/L of fluoride. The City uses hydrofluorosilicic acid to adjust the fluoride level to meet CDC's recommendation. The estimated cost of this chemical for FY22 is $26,384.00/year for approximately 68 tons.
Hydrofluosilicic Acid bids were as follows for 40,000 lbs. shipped:
1. Alexander Chemical, $388.00 per ton
Pebble Quicklime
The WTP uses quicklime for softening drinking water. The WWTP uses quicklime for biosolids conditioning to meet regulatory requirements for land application. The estimated cost for this chemical in FY22 is $617,050.00 for the WTP (approximately 4,300 tons) and $100,450.00 for the WWTP (approximately 700 tons), which totals $717,500.00/year for approximately 5,000 tons.
Pebble Quicklime bids were as follows:
1. Carmeuse, $128.00 per ton
2. Graymont Western, $143.50 per ton
The lowest priced bidder was not chosen because they received the lower score from all participating utilities based on the evaluation criteria of:
1. Price competitiveness (30%)
2. Experience (30%)
3. Delivery Requirements (30%)
4. Content of Proposal (10%)
Ferric Chloride
The WWTP uses ferric chloride for the removal of phosphorus to levels specified in its National Pollutant Discharge Elimination System (NPDES) permit. Especially during summer months, phosphorus removal becomes critical and the addition of ferric chloride improves the plant's ability to remove phosphorus from the wastewater. Violation of NPDES permit requirements could result in significant fines of up to $25,000.00 per day per occurrence being imposed on the City by the Michigan Department of Environment, Great Lakes and Energy. The estimated cost for this chemical in FY22 is $50,320.00/year for approximately 85 dry tons.
Ferric Chloride bids were as follows:
1. PVS Technologies for $592.00 per dry ton
2. USP Technologies for $888.00 per dry ton
It is recommended that purchase orders be awarded to JCI Jones Chemical, Alexander Chemical, Graymont, and PVS Technologies as the lowest responsible bidders, respectively, for sodium hypochlorite, hydrofluorosilicic acid, pebble quicklime, and ferric chloride for FY22.
It is also recommended that the purchasing agreement may be renewed for three (3) additional (1) year periods, provided both parties agree to the extension, subject to the availability of funding, and limited to the price escalation tied to the PPI for basic chemical manufacturing (code 3251). It is also recommended that should chemicals required for operations not be available from the primary vendor that a purchase order be allowable to supply the plants from the next highest bidder.
Budget/Fiscal Impact: Funds are specifically budgeted and are available for these purchases in the approved FY22 Operation and Maintenance Budget for the Water Supply System Fund and Sewage Disposal System.
