When do I need to contact a Professional Soil Classifier?

You need to contact a Professional Soil Classifier (PSC) when your lot has been evaluated by the Department and it will not pass for a conventional septic system. You may also contact a PSC if you are in a time crunch and need to expedite the application process. To learn more about expediting the application process, please see the expedited options. 

Where can I find a list of Professional Soil Classifiers (PSCs)?

The SC Department of Labor, Licensing and Regulation (SC LLR) licenses PSCs. A list of licensed PSCs can be found by visiting http://llr.sc.gov/soil/PDF/SoilRoster.pdf.

Forms Used by Professional Soil Classifiers

• Site and Soil Evaluation Form (D-1774): This form should be used by PSCs when submitting soils work to the Department.
• Soil Report Verification Form (D-3269): This form should be used by PSCs in addition to a Site and Soil Evaluation Form (D-1774) when submitting soils work to the Department for any system standard within Regulation 61-56, except for System Standard 610 – Specialized Onsite Wastewater System Designs.
