FIRST ADDENDUM TO INVITATION TO BID

PURCHASE OF ALUMINUM SULFATE

CLEAN WATER SERVICES

ISSUED: NOVEMBER 1, 2023

Clean Water Services’ (District) Invitation to Bid for the Purchase of Aluminum Sulfate dated October 27, 2023 (ITB) is hereby amended as follows:

1. Contract Duration. District is changing the duration of the Contract. Delete all dates that refer to a twelve-month Contract through November 30, 2024 and replace with an 11-month Contract through October 31, 2024.

2. Delete Section 14 of Exhibit B of the Contract and replace it with the following:

“14. If the Contract is renewed, on or about October 15, 2024, the parties will establish a new 12-month price for the aluminum sulfate based on the percent change from December 2023 through September 2024 in the United States Bureau of Labor Statistics Producer Price Indices for Sulfuric Acid, ID No. WPU0613020Tl, and Aluminum Compounds, ID No. WPU06130209 (collectively, Indices). The new price shall go into effect on November 1, 2024. For purposes of these price adjustment calculations only 75% of the price will be adjusted. Of the 75%, 60% will be assigned to the Sulfuric Acid Index, and 40% will be assigned to Aluminum Compounds Index.

This adjustment will be applied to 75% of the price. This calculation plus 25% of the price will create the new price for the next 12-month period.

The adjustment formulation is as follows:

((price* .75) * price adjustment percentage)+ (price*.25) = new price for the next 12-month period

Example Calculation with Initial Bid Price of $100.00 per dry ton Index Calculations

Sulfuric Acid Index Value for December 2023: 179 Sulfuric Acid Index Value for September 2024: 187 So, ((187-179)/179= 0.0447 Price Adjustment Percentage Aluminum Compounds Index Value for December 2023: 143 Aluminum Compounds Index Value for September 2024: 149 So, ((149- 143)/143= 0.0419 Price Adjustment Percentage

Adjustment Calculations

$100.00 * .75 = $75.00, amount to be adjusted, $25.00 not to be adjusted Sulfuric Acid Portion .60 * $75.00 = $45.00, so, $45.00*1.0447 = $47.01

AD08-18 First Addendum

Aluminum Compounds Portion .40 * $75.00 = $30.00, so, $30.00 * 1.0419 = $31.26 Hence, $47.01 + $31.26 = $78.27, Adjusted Portion So, $78.27 + $25.00 = $103.27/dry ton, New Adjusted 12-Month Price

All price changes will be calculated up or down and will be calculated to the hundredth of a percent without rounding. Indices information will be limited to that which is available on the date of the price change, regardless of whether the Indices are subsequently revised.”

Except as modified in this Addendum, the ITB will remain in effect as originally written.
