Solid Waste Authority Looking for Further Expansion

The Horry County Solid Waste Authority (SWA) is preparing to request a Determination of Need from the South Carolina Department of Health and Environmental Control for permission to further expand capacity at its Highway 90 landfill.

The request, expected to be sent in next month, will begin the process to add a Phase III Piggyback landfill cell for Class 3 Municipal Solid Waste (MSW) and expansion of the current Class 2 Construction and Demolition (C&D) waste landfill.

The SWA says it needs this expansion to continue serving the needs of the residents of Horry County for landfill capacity.

Included in the plans for Phase III is a proposed bridge over Sterritt Swamp and a new roadway snaking through wetlands areas on the authority’s 1187 acre tract adjacent to the current landfill site. The bridge and roadways are needed to mine approximately one million square yards of dirt on the 1187 property and haul it to the landfill for construction.

It is only 18 months ago that the SWA was literally begging Horry County Council to approve an increase in tipping fees at the Hwy 90 landfill to keep the authority solvent. The need for the increase in fees was blamed on capital expenditures associated with current Phase II Piggyback Expansion and planned Vertical Expansion for the MSW landfill.

Horry County Council approved an immediate $7 per ton increase in tipping fees for MSW with additional $1 per ton increments for seven more years and a $1 per ton increase for C&D.

The SWA landfill sits in an environmentally sensitive area surrounded by Sterritt Swamp on three sides. Its origin dates back to open, unlined garbage dumps that served the City of Conway since the 1960’s.

As the state was preparing what would become the South Carolina Solid Waste Policy Management Act of 1991, Horry County Council formed the SWA, by county ordinance 60-90, to conform with the new state law.

A hydrology report prepared in 1990 by HDR Engineering stated that no soils in Horry County were listed as fair to good for landfills. The 1990 report and several subsequent through 2001 stated the Hwy 90 landfill site was hydrologically unsuitable for a landfill due to the proximity of Sterritt Swamp.
