The table below summarizes our preliminary opinion of the cost for preparing permit
applications for Phase IV (the application fees are NOT included). Our opinion is based on
our understanding of: (i) the current NHDES AoT and Solid Waste Rules; (ii) our experience
preparing Type I-A permit modification applications in New Hampshire and similar permit
applications in other states; and (iii) our understanding of the type, extent, and quality of
the readily available information that can be used for the preparation of the AoT and Type
I-A permit modification applications. Additional assumptions made to develop the opinion
of cost are outlined towards the end of this letter.
TASK PRELIMINARY OPINION OF COST
Prepare AoT application $50,000
Prepare Type I-A permit modification application $250,000
Estimated Total Fee $300,000
The above preliminary opinion of cost is for engineering services during fiscal year 2017.
At this time, we recommend that the City budget and additional $200,000 for future fiscal
years for Sanborn Head to: (i) address NHDES comments to the AoT permit application and
Type I-A PMA; (ii) provide support at public hearings and meetings; (iii) prepare the Type
II PMA; and (iv) assist with preparing construction bid documents.
In addition to the costs identified above, the fee for Type I-A permit application is
estimated to be at least $20,000 (see Env-Sw 310.07). Furthermore, the AoT permit
application fee for the project could be on the order of $6,200 (Env-Wq 1503.32).
