Sludge Management Plan
To Whom It May Concern,
Please be advised that the excess solids and sludge generated from this facility is currently processed through a sludge box
dewatering system. The concentrated solids are then hauled by a carrier and disposed of at an approved disposal site. Should
there be a need, we also have other alternatives to haul liquid sludge from various contractors to approved disposal sites.
If you should have any questions or need any additional information, please do not hesitate to call Danny Lassiter at 252-240-
1398 or by email at dwlassiter@uiwater corn
