Subject: Compaction Modification Request, Concurrence
Permit No. 1812-INDUS-2008, Duke Energy Marshall Steam Station
Catawba County, 26747

Dear Ms. Hardin:
On September 20, 2016 the Division of Waste Management Solid Waste Section (Section)
received Duke Energy’s request entitled;
Industrial Landfill No.1 Compaction Modification Request, Permit No.: 1812-INDUS, Marshall
Steam Station, Catawba County, Terrell, North Carolina 28682. Prepared by Duke Energy.
September 2016. DIN 26746.
In the letter Duke Energy requested revising the approved Operations Plan to change the
minimum compaction requirement from 95 percent of Standard Proctor (ASTM D 698)
maximum dry density to 90 percent for the intermediate cover compaction specification on
exterior slopes at Marshall Steam Station’s Industrial Landfill. The Section concurs with Duke
Energy’s request. Furthermore, the Section requests that the next time the permit for the Marshall
Steam Station is either amended or modified that the change be incorporated in the Operations
Plan.
Should you have any questions regarding this matter you may contact me at [phone] or at
[e-mail].
Sincerely,

Larry Frost, Engineering Project Manager
Permitting Branch, Solid Waste Section
Division of Waste Management, NCDEQ
