Bruce,
Ray Belair is waiting on a report from your office regarding the sewer tie-in at Kimball Avenue before he issues
the CO on Lot 7. The work was done this past May. During the inspection, the representative from your office did
not want the native material put back into the excavation, so Ireland brought in new material and backfilled as
directed. I have included a photo layout of the work for your records, and to help along with the report to Ray.
Can you please copy me on your report to Ray so I can add it to our records? Thanks.

RE: Engineer's Certification(WW-4-1506)—Technology Park Lot 7
Dear Wastewater Management:
This letter is in response to Condition# 11 of the Water Supply and Wastewater Disposal permit#WW-4-
1506 issued on April 9th,2001. We observed construction of building sewer,pump station,force main,and
gravity sewer that serve this project,on several dates in the Fall of 2006 using a reasonable standard of care
customary for this scope of work.
Listed below is a brief sumrnary of our findings:
1. The contractor is S.D.Ireland Company.
2. The pump station is an 8' diameter pre-cast concrete structure that contains the pumps(duplex
system)and floats,with an exterior mounted control panel and alarm. The pumps are Barnes
4XSE3034A submersible non-clog pumps(3.0 HP).
3. The pump station valve pit is a 5'diameter concrete structure that contains the associated gate
valves and check valves.
4. The junction manhole is a 6'diameter concrete structure that contains the associated gate valves and
check valves.
5. The pump station vent was installed with an odor control device.
6. The force main is 4-inch DR18 PVC. A hydrostatic pressure test was conducted on the 4-inch
force main. Pressure was established at 58 psi. The pressure held constant for a period in excess of
2 hours with no measurable loss.
7. The 3-inch DR 18 PVC force main that was constructed from the east side of Community Drive to
the force main discharge manhole was hydrostatically tested. Pressure was established at 64 psi.
The pressure held constant for a period in excess of 2 hours with no measurable loss.
8. Manholes 1-7 were vacuum tested to 10 inches of mercury. All of the tested manholes lost less
than the allowable 1-inch drop in vacuum pressure,and all structure vacuum pressures remained
above the minimum of 9 inches of mercury(see attached test results). Manholes 1-7 passed their
respective vacuum tests.
9. The 8-inch SDR 35 PVC gravity sewer lines linking the manholes,as well as the gravity sewer
connecting the gravity collection system to the existing manhole at Kimball Avenue,were air tested
to the applicable pressures. All of the tested lines held steady pressures throughout the test duration,
and passed(see attached test results).

Based on the above observations,this letter can serve as confirmation that the system was installed in
general conformance with the approved plans. This does not relieve the contractor of minor adjustments
that may be needed during the initial startup of the system,nor does it relieve the owner of proper use and
maintenance. This letter is not intended to imply any type of warranty or guarantee from the engineer since
both the use and maintenance are beyond our control. However,given the good workmanship of S.D.
Ireland Company,we are not anticipating any problems.

RE: Technology Park Lot 7—Municipal Sewer Connection Certification
Dear Bruce:
I am writing regarding the municipal building connection to the pump station at Lot 7. I observed the
connection to the pump station on 11/15/06 and have attached photos from that site visit. The service
connection was installed in general conformance with the approved design plans,and in general
conformance with the State of Vermont Wastewater System and Potable Water Supply Rules. The entire
connection was bedded in stone. Given the proximity of the pump station to the building,the entire pump
station excavation was also backfilled with crushed stone,to prevent settlement of the pump station,pipes,
and surface area around the station.
The attached photos show the building connection very clearly. Also,please see the attached State
certification that was prepared to comply with conditions of the site's Wastewater System and Potable
Water Supply Permit.Please let me know if you require any additional information regarding the
connection. I can be reached at(802)879-6331.
Very truly yours,
