To complete our FY 2022 general engineering services scope and to maintain compliance
with the New Hampshire Solid Waste Rules, we still need to complete the following tasks:
= Prepare the Federal Greenhouse Gas Report;
= Prepare the Annual Air Emissions Inventory;
us Prepare the Annual NMOC Emission Rate Report;
=» Provide groundwater reporting services associated with the April Groundwater
Management Plan data transmittal;
«s Complete and submit monthly groundwater assessment/IRA status reports for the Phase
III leachate release including data QA/QC and data evaluation reports with figures as

As part of our general engineering task, the City recently requested that Sanborn Head
provide recommendations associated with the City’s current stormwater management
practices within the active landfill. As such, we will prepare a letter that: describes the
current practice; evaluates the factors impacting the effectiveness of managing runoff,
approximates the anticipated runoff rates and volumes; and provides recommendations on
how to better manage stormwater runoff moving forward. We recommend an allowance of
$15,000 for Sanborn Head to work collaboratively with the City on this matter.
Budget Adjustment
Sanborn Head recommends that the City budget $66,000 to complete the remaining scope
items in order to maintain compliance with the Solid Waste Rules. This budget adjustment is
broken down as follows:
a Air Permitting - $6,000
=» Groundwater Reporting - $35,000
a Financial Assurance Update - $5,000
= General Engineering - $20,000
The budget estimate is based on our Fiscal Year 2022 fee schedule with the City.
Acceptance
We understand that acceptance of this updated budget adjustment will be provided in a City
issued Purchase Order to Sanborn Head for these services.
