DATE: June 17, 1.985 :
;-
Regarding our recent phone conversation about an alternate sewer
plant location somewhere west of the City off the lake front, wp
have prepared an es'timate of time and expenses (Plan'Of~Study
attached} to accomplish the following:
1. Brief feasibiliEty study regarding an alternate sewer plant
site location. This study would primarily be aimed at
identifying the costs involved with relocation of the plant
and comparison with the costs for the current 201 Plan to
determine if it is a more cost-effective solution, which it
must be to qualify for the grants.
2. Detailed preliminary engineering and 201 Amendment if the
Feasibility Study indicates that an alternate plant site is
desirable and cost effective.
The estimated cost of the feasibility study (Item 1. above) is
$13,000 and would take approximately two (2} to three (3) weeks
to accomplish once the City designated a suitable alternative
plant site. The Detailed Preliminary Engineering and 201 Plan,
Amendment (Item 2. above} would cost approximately $35,000 and
would take an additional four (4) to six (6) weeks to complete
for submission to DER. Another public hearing would then be
required and State and other agency reviews and approvals of the
modified 201 Plan would be needed. We have not included costs
for land appraisals for the existing sewer plant site or the new
location, which would most likely be the best way to handle that
part of the comparison.

RE: Additional Work Items
Sanford Was~water System Improvements
CPH Project~No. S0602.01
During the past month, we have written ~ou regarding the need
for so=me additional studies and/or work for the referenced
project. BecaUse of the very tight temporary operating permit
schedule and the upcoming decision which will he required in
late July or early August of this year regarding the grants, we
recommend that the City Quickly consider and proceed with
certain selected work items from those listed below:
1. ALTER~NATE SE~ER PLANT LOCATIOt~ -
We have written you separately on this matter.
2. EVALUATION OF GPANT POSSIBILITIES WITH AWT AND LAKE
DISCHARGE -
Discussion: When the SSAC recommendation is issued by
the Hearing Officer (projected to occur in July
August 1985), the City can elect to proceed with AWT
and Lake Discharge {assuming City wins) or can pursue
Land Application with grants. Also, thc decision from
the SSAC may not be real clear and may need
clarification and a subsequent wasteload allocation
from the State even if the City basically won. It
would be important to know if any grant funds would be
available if the City wins the AWT issue. For example,
it would be highly desirable to try to retain the
grants for Sewer System Rehabilitation and the
construction of Sludge Facilities.
Estimated cost of study to determine the City's revised
priority score with AWT and discharge and consult with
FDER on same $1,000.
3. AWT PLANT PRELIMIHARY ENGINEERING
The current 201 Plan' is based upon Secondary treatment
and land disposal. If the City prevails in its pursuit
C~nklin, Porter end Holmel
of Site Specific Alternative Crt:teriai(SSAC) and.iS
allowed to upg'rade:its=sewer pl:ant to advanced
treatment and centin~e a lake d~scharge, it w~ll be
necessary to determine how the plant cap he converted
to AWT and the costs involved. There are numerous
processes and variations possible. No work on this
aspect has been performed to date and previous costs
presented for AWT were general and very rough co~ts and
not/Specific for the Sanf~rd case. A more accurate
costiprojection of capital and operating costs may
affect the City's decision regarding:which course of
action to pursue. Als6, having AWT preliminary
engineering done may save several months time in
implementing improvements if the AWT alternative.is
followed and could help shorten t'he length of possible
sewer moratoriums.
Estimated cost - $17;n00 See attached detailed Plan
of S~udy.
4. LAND APPRAISALS
DiscUssion: If the City pursues the Grants Program and
Land Application of Effluent, it will he necessary to
obtain two {2) independent appraisals and one (1)
review appraisal of the Land Application site. The
schedule approved by DER for the City's temporary
operating permit reouires that appraisals he initiated
by July 1985. The appraisal will also provide
important information to the City to assist in making
the decision regarding pursuit of SSAC and a Lake
Discharge or Land Application of Effluent with grant
funding. The land cost is a very significant part of
the overall cost for a land application solution and a
more accurate estimate of land cost may affect the
decisions to be made by the City.
Costs Previous estimates for the appraisals were
provided the City, with a range of $15,000 $20,000
for all the appraisals. We are currently receiving
quotations from FDCT listed appraisers to more
accurately tie down the cost of making the 2
independent appraisals and 1 review appraisal required.
5. IMPACT FEE / USER CHARGE STUDIES
Discussion - Impact Fee Study - Because of the large'
monetary expenditure necessary to solve the City's
wastewateri treatment and dispnsal problems, regardless
