NOTICE OF STATE DRAFT 6 NYCRR PART 373 PERMIT MODIFICATION
NOTICE OF LEGISLATIVE PUBLIC STATEMENT HEARING
NOTICE OF PUBLIC COMMENT PERIOD

APPLICANT: CWM CHEMICAL SERVICES, LLC

APPLICATION NO: EPA ID No. NYD049836679
DEC No.: 9-2934-00022/00097

PROJECT LOCATION: CWM Chemical Services, LLC
1550 Balmer Road
Model City, NY 14107

PROJECT DESCRIPTION: Applicant CWM Chemical Services, LLC (CWM) has applied for a modification of its existing Part 373 permit to allow the utilization of an alternative final cover design for the facility's existing 47 acre hazardous waste landfill known as Residuals Management Unit - One (RMU-1). The proposed modification would increase the landfill's currently permitted waste disposal capacity by about 106,870 cubic yards (3% increase). However, this permit modification will NOT increase the overall topographical size of the RMU-1 landfill beyond its currently permitted limits (i.e., this will NOT result in any increase to the landfill's overall area or height). CWM submitted a permit modification application to DEC in April 2008, with subsequent revisions submitted in June 2008. DEC has reviewed this application and has TENTATIVELY DETERMINED the application to be complete pursuant to 6 NYCRR Parts 373 and 621. As a result, DEC has prepared the appropriate DRAFT permit modification for public review. The current permit will expire in 2010.

The RMU-1 landfill is constructed with a double-composite liner/leachate collection system and is divided into ten (10) cells for separate leachate collection. Currently, about 5 2 cells have been closed with the remainder in operation and receiving waste. At closure, a final cover is required to be installed to prevent precipitation from contacting the waste and producing contaminated runoff from the landfill, and to reduce leachate generation. This proposed permit modification would allow CWM to utilize an alternative final cover design on the remaining areas of the RMU-1 landfill which are still in operation (i.e., currently receiving waste). The primary differences between the current final cover design and the proposed alternative final cover design are: 1) the replacement of a two (2) foot thick compacted clay layer with a Geosynthetic Clay Liner (GCL) and a six (6) inch thick select fill layer; and 2) a twelve (12) inch reduction in thickness of the general fill protective layer. The GCL is considered an equivalent hydraulic barrier and the CGL is more resistant to degradation from freeze-thaw cycles than the compacted clay. This alternative design would result in a reduction in the overall thickness of the final cover, facilitating a proposed estimated increase of the landfill=s currently permitted waste disposal capacity from approximately 3,495,030 to 3,601,900 cubic yards (3% increase).

DEC has prepared a Fact Sheet for the public=s use which provides further details on this DRAFT permit modification and associated opportunities for public involvement in the process.

PUBLIC HEARING: Pursuant to 6 NYCRR 621.8, a legislative public hearing for the receipt of public comment on the DRAFT permit modification and CWM's application will be held on December 15, 2008 at:

The legislative hearing will be conducted in two (2) sessions, the first beginning at 4:00 p.m. at the high school and the second beginning at 7:00 p.m., also at the high school.

SEQR STATUS: Pursuant to the State Environmental Quality Review Act (SEQR, ECL article 8 and 6 NYCRR part 617), DEC has determined that the proposed action described above, is a Type 1 action and will not have a significant effect on the environment. A Negative Declaration for this action is on file at DEC=s Region 9 Office. This determination was made on the basis of an Environmental Assessment Form submitted by CWM. As a result of this SEQR Negative Declaration, DEC has determined that this DRAFT permit modification is not subject to the provisions of NYS ECL Article 27, Title 27-1105(1), which requires a certificate of environmental safety and public necessity.

TENTATIVE DETERMINATION: DEC has found the CWM permit modification application complete and has made a tentative determination to issue the permit modification for the aforementioned changes associated with the RMU-1 landfill. The DRAFT permit modification has been prepared pursuant to the applicable regulations in 6 NYCRR Part 373-2 (Final Status Standards for Owners and Operators of Hazardous Waste Treatment, Storage and Disposal Facilities).
