Air Quality & Water Quality

Air pollution is becoming a more significant issue in South Carolina as we are faced with the challenges of complying with national air quality standards. It is imperative that we meet these standards while still promoting the economic well-being of the state.

Air Quality Coalition

The WRCOG Air Quality Coalition is one of seven regional groups in South Carolina dedicated to improving the state’s air quality. The Waccamaw Air Quality Coalition was formed to serve as a forum to discuss air quality concerns and ideas for the tri-county region (Georgetown, Horry, Williamsburg counties). The coalition serves as a resource to exchange information about regional air quality concerns and to obtain input from stakeholders as we work to address these issues in a coordinated and proactive effective manner. The Coalition meets quarterly and is open to any member of the public, local industry, municipality, or other agency that has an interest in air quality issues.

Those who wish to be notified of upcoming meeting times and dates or those who have suggestions on future agenda items or topics should contact Elizabeth Tucker (843-436-6136 or

Statewide Early Action Plan

In South Carolina, 45 of the 46 counties are participating in an Early Action Plan, in partnership with the South Carolina Department of Health and Environmental Control (DHEC) Bureau of Air Quality (BAQ).

The WRCOG region is in attainment with all air quality standards in the Federal Clean Air Act and its amendments. The three counties, however, agreed to enter a statewide partnership in 2002 to proactively address air quality issues before they become a problem. The Early Action Plan determines what actions must be taken at the state and local level to ensure compliance with recently adopted federal regulations regarding ozone emissions.

Water Quality

Section 208 Water Quality Management:

Notice of the Proposed Major Amendment to the Waccamaw Region Section 208 Water Quality Management Plan

The principal objective of the Section 208 program is to maintain and improve water quality as it relates to the classification of surface waters in the Waccamaw Region. The program is funded by local 208 partner management agencies, supplemented by 205J grant funds from the Department of Health and Environmental Control (DHEC). Through an on-going agreement with DHEC, the Section 208 Program Coordinator reviews all wastewater permit applications in the Waccamaw Region to ensure that they are consistent with goals of the “Waccamaw Region Section 208 Water Quality Management Plan.”

In FY2010-2011, the WRCOG was afforded the opportunity to update the “Waccamaw Region Section 208 Water Quality Management Plan” via an American Recovery and Reinvestment Act grant issued to SC DHEC. This has allowed the WRCOG Section 208 program to reevaluate existing water quality issues and assess new strategies to address future concerns that may affect the region.

The Section 208 Program Coordinator works with sewer providers to identify cost effective, environmentally sound alternatives to upgrade/expand wastewater treatment facilities in the Waccamaw/AIWW System and other parts of the region. The Program Coordinator also works with local governments on non point source pollution issues.

2016 Hog Inlet- Dunn Sound Creek Watershed Plan

The Hog Inlet- Dunn Sound Creek Watershed Plan was made possible by a 319 grant funded by SC DHEC. Project partners include Horry County Stormwater Department, North Myrtle Beach, and the Horry Soil and Water Conservation District. The primary focus of this planning effort is to address the fecal coliform bacteria water quality impairments which have resulted in Shellfish Harvesting restrictions within the estuary.

Below are attachments of the Hog Inlet – Dunn Sound Creek Watershed Plan:
