Project Spotlights:

Hartsville, SC

Duke Energy, H.B. Robinson Plant

• WEC provided regulatory consultation services regarding 316(b) compliance for Duke Energy’s H.B. Robinson Plant. Duke needed to evaluate the thermal dilution from the lake discharge and understand the cause of stringent Whole Effluent Toxicity (WET) and metals limits.

• Services included measurements of in-stream velocity, bathymetry, and temperature and development of an EFDC numerical model to evaluate localized mixing within the lake. WEC provided recommendation for future NPDES limitations and reduced the biological assessment requirements performed for 316(b) compliance.

Evonik Corporation, Bushy Park Facility-Water-Environment-Consultants-background
North Charleston, SC

Evonik Corporation, Bushy Park Facility

• Evonik Corporation was evaluating two potential sites for a new, precipitated silica plant, and obtaining a favorable NPDES permit was a primary deciding factor. WEC obtained the required NPDES and wastewater construction permits for the treatment and discharge of a highly salty wastewater into the Cooper River, South Carolina.

• WEC used the CORMIX model to design a single-port diffuser resulting in favorable whole effluent toxicity limits and the EFDC model to ensure the discharge would not affect the dissolved oxygen within the river.

Saluda County Water and Sewer Authority
Saluda County, SC

Saluda County Water and Sewer Authority

• Saluda County Water and Sewer Authority proposed a new, larger WWTP but was unable to acquire a new wasteload allocation at the existing site discharge due to existing dissolved oxygen impairments withing the Little Saluda River.
• Under contract with MDB Consulting Engineers, P.A, WEC completed field measurements and water quality modeling of the proposed discharge to demonstrate the project’s compliance with state water standards, potentially saving millions in project capital costs.
Santee Cooper, Cross Station Flow Analyses and Modeling-Water-Environment-Consultants
Cross, SC

Santee Cooper, Cross Station Flow Analyses and Modeling

• WEC provided regulatory compliance support for Santee Cooper by evaluating low and average annual instream flow rates used by the SC Department of Health and Environmental Control (SCDHEC) to establish permit limits.

• WEC used the CORMIX model and revised flow to establish whole effluent toxicity limits and recommendation for a multiport diffuser system to improve mixing.

Maintenance Dredging Permitting for Multiple Terminals-Water-Environment-Consultants
Savanah, GA

Maintenance Dredging Permitting for Multiple Terminals

• WEC provided permitting support for a number of Savannah Harbor commercial terminal owners (including Georgia Ports Authority, ConocoPhillips, Georgia-Pacific Gypsum, NuStar Energy, and others) to conduct maintenance dredging in the Savanah Harbor.

• The project, which included 20 terminals in total, required careful consideration of environmental effects, water quality standards, and fishery resources. WEC conducted Tier I Sediment Quality Evaluations, an Essential Fish Habitat Assessment and Biological Assessment, and evaluated water quality effects in support of the permit applications.

Effluent Diffuser Discharge Modeling and Design-Water-Environment-Consultants
Charleston, SC

Effluent Diffuser Discharge Modeling and Design

• The WestRock paper plant’s existing effluent discharge within the Cooper River creates a thermal plume that attracts manatees and interferes with their normal migration pattern.

• WEC conducted depth and tidal current velocity measurements to set up and calibrate a model (EFDC and CORMIX) to simulate the discharge’s thermal mixing within the Cooper River.

• The results aided in evaluating an appropriate outfall diffuser location. Through open communication and a collaborative approach, WEC provided the preliminary design of the outfall diffuser and permitting support to increase mixing and reduce the thermal impacts.

Archroma NPDES Permitting Support-Water-Environment-Consultants
Martin, SC

Archroma NPDES Permitting Support

• While maintaining its primary business focus, Archroma found itself with extra capacity in its treatment system and a favorable discharge location in the Savannah River.
• WEC worked with Anchroma and SCDHEC to negotiate an NPDES permit allows Archroma to leverage its treatment capacity for additional revenue.
Modeling, NPDES Permitting, and Construction Permitting Dominion Energy, A.M. Williams Station -Water-Environment-Consultants
Goose Creek, SC

Modeling, NPDES Permitting, and Construction Permitting Dominion Energy, A.M. Williams Station

• WEC was awarded the contract to provide regulatory compliance support to multiple plant projects requiring specialized, fast-tracked NPDES and wastewater construction permits.

• Services included numerical modeling through the CORMIX and EFDC models and NPDES and construction permitting support. The project required close coordination with the design firms (Fluor) to lower the treatment system cost and expedite permitting process.
