SBR #2 INCIDENT MARCH 8, 2006
Mr. Regan recapped the incident that occurred on or about March 8, 2006 that caused a problem with the SBR#2. The bacteria in SBR#2 died off for an unknown reason. The effluent being discharged was not completely treated. Mr. Bozza stopped the discharge immediately and notified DEP of the problem. Corrective steps were immediately taken. The effluent has been trucked to Danbury. Replacement sludge with bacteria to "seed" SBR #2 was brought in on Friday. The plant is being constantly monitored, including over the weekend. On Monday, additional testing indicated the bacteria was dieing off again. Veolia has brought in an expert for consultation. A recommendation to pump out the bottom sludge (approximately 25,000 gallons) from SBR
#2 was made and this was accomplished. Approximately 25,000 gallons of reactivated sludge with extra bacteria was brought in from the Danbury STP.
Mr. Bozza reported that currently he is not sure when SBR #2 will be ready for normal operation and discharge. The wasting sludge is still being trucked to Danbury. At this time, the costs of the effluent/sludge removal and replacement of sludge are not known.
Samples from SBR #2 will be tested to attempt to determine what entered the system that caused the problem. Veolia will have someone available tomorrow to begin the testing process. Coverage of costs through insurance will be pursued.
In addition to DEP notification, the Town’s health officer, Doug Hartline, has been notified of the problem. Mr. Regan will discuss the incident with Police Chief Fuchs in order to file a report on the incident. First Selectman Ketcham has already requested that the police again be aware of suspicious trucks parked in the Georgetown area.
Mr. Campbell left the meeting at 7:00 pm.
PHOSPHOROUS TREATMENT REQUIREMENT
The phosphorous treatment issue with the new plant was discussed. Steven Soler recapped the situation with the DEP permit and the phosphorous issue. The discharge permit for the new plant has been signed and issued by DEP, dated 11/30/05. During the public notice period, the permit was appealed. Following lengthy discussions and negotiations, GLDC agreed to incorporate a phosphorous treatment system in the new plant and all issues on the table were eliminated. The Commission was asked for a written confirmation regarding accepting a phosphorous limit. Current discharge concentration of phosphorous was reviewed with Mr. Bozza along with the standard treatment season (warm weather) and the complications of partial removal.
Motion: That regarding the additional requirement for the Phase 3 wastewater treatment facility for phosphorous limits requested during the appeal of the DEP permit, the Water Pollution Control Commission agrees to accept, based on weekly sampling in accordance with DEP standards, a 2 mg per liter total phosphorous seasonal monthly limit during the standard treatment period between May 1 and October 1. Moisio, Stroetzel. Approved. Unanimous.
ADJOURNMENT
The acting chair adjourned the meeting at 8:07 p.m.
Respectfully submitted,
Mary Maday, Recording Secretary
