Public comment on whether a Long Island trash company that loads garbage onto rail cars can expand has been extended an additional 30 days, the state Department of Environmental Conservation said Friday.

One World Recycling in Lindenhurst has applied to increase its daily tonnage limits, the agency said.

Its current permit allows the company to transport up to 370 tons per day of construction and demolition debris and commercial waste by rail.

An emergency authorization was issued after superstorm Sandy, which allowed the facility to operate at 1,100 tons per day, according to a news release. The permit modification will end the facility's work under the emergency authorization and will limit facility operations to 500 tons per day.

Upon completion of a proposed building expansion, One World would be authorized to operate at a rate of 650 tons per day and at no time exceed 800 tons on any given day.

The agency will not make a final determination on the draft permit modification and renewal until it has fully reviewed all issues and public comments, the DEC said.

Written public comments will be accepted until the close of business on Aug. 10. Written comments can be submitted by email to OneWorldRecycling@dec.ny.gov or mailed to: Mark Carrara, NYSDEC, SUNY @ Stony Brook, 50 Circle Rd., Stony Brook, 11790-3409.
