Industrial Pretreatment Program

Industrial Pretreatment Program


Industrial Pretreatment Permits are required of industries that are “Categorical” (such as industries relating to Textile Mills, Metal Finishing, Organic Chemicals, Plastics & Synthetic Fibers, Aluminum Forming etc.), industries with effluent >5% of dry weather hydraulic or organic capacity of the Waste Water Treatment Facility (WWTF), industries with effluent > 25,000 gallons/day of process wastewater, or industries that have the potential to adversely affect the Waste Water Treatment Facility’s compliance with its NPDES permit. There are 17 permitted industries with the Greenwood Metropolitan District.


The purpose of the Pretreatment Program is to control the introduction of pollutants that could damage the treatment system or cause interference, prevent pass through of untreated constituents, prevent contamination of biosolids and to protect the safety of GMD personnel and GMD operations.


The Waste Water Treatment Facility’s treatment capacity is determined by a “Headworks Analysis”. Some of the treatment capacity is allocated to residential users and some treatment capacity is allocated to industrial users. GMD manages treatment capacity by permitting industries. The Pretreatment Program includes, GMD permitting and inspecting the industries for compliance, annual sampling by GMD, periodic (typically monthly) self-monitoring and reporting and, daily effluent flow monitoring by the industries. GMD is responsible for enforcement of the permit limits, compliance with its NPDES permits, reporting a pretreatment summary semi-annually to SCDHEC, publishing Significant Non-Compliance (SNC), and recognizing exceptional pretreatment programs within the district.

Greenwood Metropolitan District recently recognized local industries for their outstanding compliance record with their pretreatment permit. Pretreatment permits are required for users that have the potential to impact the publically owned wastewater treatment plants due to the nature of their business. The 2012 silver award recipients were Carolina Pride Foods, Eaton Corporation Hydraulics Group, Eaton Electrical, Greenwood Fabricating and Plating, and Greenwood Mills Harris Plant.  The 2012 gold award recipients were Ascend Performance Materials, Center Manufacturing, CNC Plating, Cooper Power Systems, Covidien, and the Greenwood County Landfill.  FUJIFILM Manufacturing received the Palmetto Award for achieving perfect compliance with effluent water quality standards and reporting requirements for the past ten consecutive years.
