SJC Meeting, October 12, 2005
IAWWTP Conference Room
INDUSTRIAL PRETREATMENT
Staff eagerly awaits the results of the BB&L Maximum Allowable Headworks Loading Study.
TERTIARY PHOSPHORUS REMOVAL UPGRADE
Scheduling The physical connection of the existing plant to the new tertiary process is
planned for early morning on October 16th. The existing plant will be shut down for several
hours to allow the general contractor to remove a section of the 48” outfall pipe. Also,
several key process tie-ins will occur as well as the main electrical service interconnections.
Staff have contacted the DEC for their approval. The DEC has arranged for a brief tour of
the facility before giving their blessing.
All of the major processes, pumps, valves, piping, and plumbing are now in place. At this
time, construction efforts are mainly geared toward smaller project work such as
architectural items, windows, doors, painting, etc. The electrical contractor still has the bulk
of their work remaining and has promised to increase staff to insure that they will finish on
time.
Potential Change Order
The potential change order reported last month due to a redesign of the overhead door
system to the Sand and Polymer Storage Room will be less costly than originally anticipated.
The estimate reported at around $10K will more than likely be in the range of $5K This will
insure the modification of the door header and the retrofit of the door mechanism. Staff
will continue to update the SJC on this all important issue.
ENGINEERING AND OPERATIONS COLLABORATIVE EFFORTS
Evaluations on the sanitary sewer flow monitoring stations are complete and
recommendations and assessments are being finalized. The project is now ready to move
into the bid stage.
CHEMICAL BULK STORAGE
The new 1500 gallon day tank that will be used for ferric chloride storage in the new tertiary
phosphorus system is undergoing the normal registration process with the State Department
of Environmental Conservation (NYSDEC). An updated Spill Prevention Plan (a required
document by NYSDEC) was provided in draft by staff to Jeff Soule for review. Once
finalized, segments of this report will be provided to the NYSDEC as required to complete
the tank registration.
In addition, it is now time for a full 5 year inspection of one of the plant’s large bulk storage
tanks. Because of its size, 10,000 gallons, the tank requires a wall thickness evaluation as well
as a general review of fittings and appurtenances by a certified tank inspection engineer. The
inspection will require an internal review under a full confined space entry operation. Staff
has contacted a local inspection firm to provide a cost proposal for this service.
SODIUM HYPOCHLORITE ALARMS
Staff is awaiting final pricing from Koester Associates on their offerings in the residual
analyzer selection process. Once received, Jeff Soule and staff will convene to decide on the
best course of action.

OPERATORS REPORT
SJC MEETING
October 12 2005
1) Waiting on the HWL from BBL
2) The new hours for receiving truck waste went into effect October 1st.
3) Met with Susan Brock and Khandikile Sokoni regarding the contracts for
generators of truck waste. One of their questions is did the BPW approve the SJC
decision to have me sign the contracts. Another item was fees not only for truck
waste but surcharges for conventional pollutants.
4) The VFD on #4 Influent pump is has been replaced and the pump is back in
service.
5) #5 Influent pump has developed a noise that we believe to be coming from the
wear rings. We are trying to schedule a crane to come in and remove the pump.
The pump is out of service.
6) The bearings on the shafts have been replaced in # 3 final settling tank.
7) NYSERDA Enhanced Anaerobic Digestion. We have a meeting scheduled for
October 19 to discuss the project.
8) We met with two more vendors about Cl2 residual meters.
9) Industrial sampling at Emerson.
10) Met with Cornell about the Hydrolysate wastewater. They are planning on start-
up in the first quarter of 2007. One potential problem with trucking the waste here
could be the odors.
11) Plans to cut the outfall pipe to tie in the new phousphours system are set for
October 16th.
12) Dave McGeever has returned to work. Terry is still under going chemo
treatments.
