berm and other potential design modifications can be discussed. Action items from the
meeting are anticipated to include preparing:
=» Aconceptual design of an alternative perimeter berm;
= Arevised liner and leachate collection system design;
= Aconceptual design of a leachate pumping and transmission system;
=» Aconceptual liner and final cover grading plan;
= Calculations of the estimated airspace volume, construction materials quantities, and a
comparison between the proposed and alternative designs;
= Calculations of slope stability, leachate collection transmissivity; and
=» An opinion of the construction costs of the permitted design versus the alternative
design.
We anticipate preparing for and attending one meeting with the City to present the
alternative design and the engineering comparison. The desired outcome of the meeting is
direction on how to proceed with the Phase II] PMA and AoT documents.
Task 2 Solid Waste Permit Modification Applications
Sanborn Head will prepare two Solid Waste PMAs (a Type IB and a Type IJ) for the City’s
signature and submittal to the NHDES. The Type IB PMA will specifically address the
design modifications accepted by the City under Task 1. The Type II PMA will provide the
construction documents. Based on our experience working with the NHDES on similar type
projects, we anticipate submitting both PMAs simultaneously.
The PMAs will include a completed form, a brief summary of the project, and references to
supporting documentation. In addition to completing the application form, we will prepare
a cover letter for the City’s use in transmitting the application to the NHDES. Also included
under this task is the reproduction of the PMAs. In accordance with current NHDES
preferences, we plan on submitting an electronic copy of each PMA so only one paper copy
of the application package will be prepared. Likewise, we will provide the City with an
electronic copy as well as one paper copy.
Prior to submitting the PMAs, we propose having a pre-submittal meeting with the NHDES.
We anticipate that this meeting would be held in Concord at the NHDES office and would
serve to assist the NHDES in their review of the documents. Our services would also
include preparing responses to the NHDES review comments to the PMAs. At this time, the
extent of review comments, if any, is not known. For purposes of this proposal, we carried
an allowance of $5,000 to respond to comments. We will notify you if it appears that the
effort to respond to comments is greater than we assumed.
For your convenience, we estimated the fees associated with submitting the PMAs. The fee
for a Type IB PMA is $100. For the Type II PMA, the fee is dependent upon the life
expectancy of the area being constructed, and was calculated using the formula provided in
Env-Sw 310.08(a) of the Solid Waste Rules. We estimate that permit application fee will be
$17,000. Please note that we assume that the City will pay the fees directly to the NHDES at
