The Alaska Department of Environmental Conservation is accepting public comments through May 25 on a proposal to expand the Glennallen landfill at Milepost 122.5 of the Richardson Highway.

The expansion would add a one-acre Cell 2 south of the current landfill cell, which has reached capacity. Copper Basin Sanitation Service Company operates the facility on state land.

Cell 2 was built without a liner and slopes west toward a leachate collection sump. Leachate will be pumped from the sump as needed and disposed of in septage lagoons in the northwest corner of the property. The new cell will handle municipal solid waste the same way Cell 1 does, with waste placed, compacted and covered.

The expansion requires a modification to Solid Waste Disposal Permit SW2A009-30.

Permit application materials are available at dec.alaska.gov/comment. Comments can be submitted electronically at that site or mailed to Rebecca Colvin, ADEC Solid Waste Program, 555 Cordova St., Anchorage, AK 99501. Comments can also be emailed to [email protected] or faxed to 907-269-7510.

For questions about the permit, contact Annemieke Powers at 907-269-7626 or [email protected].

People with disabilities who need accommodation to participate should contact Kristin Mabry at [email protected] or 907-334-0884 at least 10 days before the May 25 deadline.
