That covering system shall be in place immediately upon exiting the sludge garage loading bay.
The cover system shall prevent odors from emanating from the containers/vehicles and shall
exclude rain, snow, or other material from the containers/vehicles.
D. If, for reasons beyond the Contractor's control (i.e., weather conditions, impassable roads, etc.),
the amount of dewatered sludge cake removed from the plant is significantly below the average
daily production or below the amount requested to be removed by plant personnel, then this amount
must be made up. On the next calendar day this left over amount must be removed in addition to
that day's normal amount removed. The Contractor shall do this at no additional cost to the City
even if the total amount for this day exceeds the peak output noted in the Information for Bidders.
The Contractor must demonstrate their transport and storage or processing capabilities to perform
at this level. This information must be attached to the Bid Proposal.
E. A monthly report for the hauling summary must be delivered, as an excel file, to the Operations
Manager by the tenth (10) day of the next month. This report will include the date, ticket/manifest
number, and the wet tons for each load. The hauling summary will be done on a calendar month
schedule.
PART 3: EXECUTION

debited or credited to the monthly invoice(s). Adjustments will be made only when the price varies
from the base price by plus (+) or minus (-) $0.05 on a monthly basis. The price is found using the
Service Month Index Price, as set forth on the EIA Retail On Highway Diesel Prices index for New
England PADD 1A (http://www.eia.gov/petroleum/gasdiesel/). The base price is set at $5.05. The
Fuel Adjustor will be made according to the following formula:
([(Service Month Index Price/Base Price) X 10% X (Price per wet ton)] - [10% X Price per wet
ton]) = Fuel Adjustor, per ton
01020-2 February 2026

The following example is provided for clarification and reference purposes only:
Service Month Index $5.20
Base Price $5.05
Price Per Wet Ton $125.00
([($5.20/$5.05) X 10% X $125.00] - (10% X $125.00)) = +$0.37 per ton
