Re: Budget Increase
FY 2022 General Engineering Services
City of Nashua Four Hills Landfill
Nashua, New Hampshire
Dear Jeff:
Sanborn, Head & Associates, Inc. (Sanborn Head) appreciates the opportunity to be of
continued service to the City of Nashua (City). As we recently discussed, the extent of
engineering services that were performed during Fiscal Year (FY) 2022 as required by the
New Hampshire Department of Environmental Services (NHDES) were not planned for in
our original budget. With this extra effort, coupled with carryover services from FY 2021, we
anticipate exceeding the approved FY 2022 general engineering services budget. This letter
presents our request for a change to the FY 2022 general engineering services budget.
Services Already Provided
Since the beginning of FY 2022, multiple requests were made by the NHDES that are beyond
that of a typical year, requiring the City and Sanborn Head to spend additional effort and
incur additional costs. Below is a list of the major scope items resulting from the NHDES
requests that were not reflected in our budgeted FY2022 scope of services that were either
completed or are in progress:
= Participated in numerous calls regarding 40 CFR Part 62 Subpart OOO requirements;
» Prepared Design Capacity and NMOC Emission Rate Reports per 40 CFR Part 62 Subpart
000 requirements;
= Prepared a Notice of Applicability Letter per 40 CFR Part 62 Subpart OOO requirements;
= Prepared the Phase III Air Dispersion Modeling Update;
« Performed additional tasks related to the Phase III Release Initial Response Action (IRA)
including: preparing a 10-day notification letter; preparing for, and attending a NHDES
site visit; performing soil sampling; and preparing, planning, providing quality
assurance/quality control (QA/QC), and reporting of the additional data;
« Coordinating with the City regarding the Phase III liner repair; and
s Coordinating with the City and preparing various documents related to the temporary
stormwater management infiltration practice area within Phase III.
