Gentlemen,
This letter report is submitted as required by article "A. (3.) - Engineering
Alternative Analysis (EAA) Requirement" in accordance with the above described
permit.
Eaistine System
The present system is permitted to discharge 0.006 MGD into a natural tributary of
Pantego Creek. It has a 500-gallon grease trap, dual septic tanks, a 5000 gallon re-
circulation tank and a re -circulating sand filter.
All components are in good condition and are well maintained. This writer is not aware
of any violations of the permit requirements.
Alternatives
There are two practical alternatives to providing disposal of sewage from the Municipal
Building.

(1) Ground Absorption System
(2) Tap into the Town of Belhaven System
Ground Absorption System
A 2.5-acre cleared site (in the vicinity of the Tennis Courts) would be used for the
absorption area. Other Ground Absorption sites may also be available in the area
or possibly a "spray or drip" irrigation system could be used to dispose of
effluent.
The estimated cost of such a system is $90,500., which includes $60,000 for the
drain field. The estimated annual cost of operation, permits, maintenance and
repairs is $1800.
Tan into Town of Belhaven System
The estimated cost of connecting to the Town of Belhaven Sewage Treatment
System is $44,000. The estimated annual cost of operation and maintenance is
$1300.
Economic Feasibility of Alternatives
Alternatives have not been evaluated because the presently permitted system is fully
funded with deflated dollars. Therefore, the present value of the existing system is zero.
The purpose of this report is to outline the characteristics of reasonable alternatives to the
present permitted system.
Data presented herein are based on this Engineer's expertise in constructing small sewage
absorption fields and adding to existing sewage collection systems. The cost of the drain
field system may vary significantly based on soil conditions, therefore any drain field
area must be comprehensively evaluated in order to arrive at a more refined cost estimate.

Mr,. O'Neil,
.As we discussed this jatoming on the phone, It is now standard pollcy, when
permitting facilities to heat and discharge wastewater, 40 require them to analyze
alternatives to discha�ge such as connection to existing facilities or land
application, before initially granting a permit. Oncs analysis is done, it is not
e' Chi
generally required agithi unless the local circumstances change or the tacility has
compliance problems.
Martin plants, such as the one in pantego, were build "before this policy was
implemented and have never done such an analysis.. While the Division is -not
requiring such facilities to convert to other alternatives and cease discharge, it is
requiring them to consider and provide intormatlon on:the technical Bad economic
feasibility of altencatives.
,rhts analysis should i Ie submitted by a Town Official, but may be prepared by
anyone the T*wn designates. It should compare the current system and costs to
the protected costs of connection to the nearest sewer line andlor land
application alternative$.
l am including our gct,dance for preparing EAAs, and I have circled the x,ertions
that would apply to thlla case.
Feel fr«°e to call with any questions,
Dalnnr JeffricW
