LEWISTON – The directors of the sewage treatment plant took no action on proposed changes to personnel policies Friday after questions about how changes could affect a union contract. The board will revisit the issue in September.

Language was added to employee personnel policies for clarification that the policies apply to all employees and that a union contract applies to union workers in instances where the collective bargaining agreement and the personnel policies differ.

Board member Norm Lamie of the Auburn Water and Sewerage District raised the questions about how the union contract could be affected.

In other business, Assistant Superintendent Myron Eames told the board that the volume of septic and holding tank waste received in July was unusually high. The Lewiston-Auburn Water Pollution Control Authority received 250,600 gallons of septic waste. The only month when the amount received was higher was October 2001, when the amount exceeded July’s total by 17,000 gallons.

“July was the biggest July and the second biggest month ever. It’s good news,” Eames said.

In another matter, Eames told the board that compost marketing for July was discouraging. After a strong start this year, sales are down slightly relative to 2002.

Eames also reported that deliveries of biosolids to farms is on target with projections through July. About 2,600 tons out of 4,000 that LAWPCA is committed to delivering has been delivered.

The board set the preliminary cost apportionment for the last quarter of this year at 58.5 percent for Lewiston and 41.5 percent for Auburn.
