Borough Mayor Dale Bagley tosses the first bag of trash into the new landfill liner at the official dedication.
The future for Alaskan landfills is here and officially operating at the Central Peninsula Landfill. At an open house last week Mayor Dale Bagley in one of his final official acts of his six years as borough mayor tossed the first bag of trash into the new polyethylene lined cell. The $7 million dollar project began in 2002 when voters approved a $12 million dollar bond proposition to finance construction and equipping of the renovations at the Central Peninsula Landfill. It is anticipated the remaining funds will not need to be expended for the second cell site until approximately 2009, “This is a recurring expansion that will be necessary to continue, through good operations we had been able to postpone the expansion until now, and we are excited with the new technology that is being implemented here,” said Cathy Mayer, KPB solid waste director.

“These lined landfills are going to be the future of landfills all over the state and required by the DEC. This liner will allow us to take waste into the landfill that we were unable to previously,” said Mayor Bagely. The composite liner consists of a geosynthetic clay liner base, overlain with a 60 mil high density polyethylene geomembrance, a geotextile drain rock layer and then sand silt to protect the liner from puncture. “Each seam had to be tested for quality control and every piece had to be mapped and tracked as it was installed,” explained Mayer.
The new cell includes a stormwater system that diverts water out of the waste. “Borough staff constructed the stormwater system by installing some 450,000 square feet of polyethylene and 2,000 plus sandbags, culverts, and pumps it addition to developing the access road,” added Mayer. The water passing through the waste will be collected as leachate and recycled back through the waste fill for treatment and disposal. “We’ll be able to get more trash in here then in a conventional landfill because of the bioremediation which breaks the waste down,” said Bagely. The cell is anticipated to last between 5 to 7 years before moving on to the next cell site that was included in the bond prop. Then according to Bagely after 10-14 years the Borough will be looking for other cell sites around the old landfill area. The upgrade puts the Borough in compliance with DEC regulations that were designed to reduce the environmental impact of landfills.
