North Carolina Cleanup Standards for Hydrocarbon Contaminated Soil
The North Carolina
Department of Environment and Natural Resources has adopted Risk-Based
Assessment and Corrective Action procedures to evaluate and remediate
releases from underground storage tanks. Please visit our Web Site at:
http://ust.enr.state.nc.us/ or call the Underground Storage Tank
section at 919-733-8486 for the most recent information.
In accordance with 15A
NCAC 2L .0115 (m), three categories of soil cleanup levels have been
established: residential, industrial/commercial, and soil-to-groundwater
maximum soil contaminant concentrations. The soil-to-groundwater maximum
soil contaminant concentrations were established to protect groundwater
from the leaching of contaminants from soil.
Cleanup Requirements
Pursuant to 15A NCAC 2L
.0115(h), soil must be remediated to the maximum soil contaminant
concentrations or as closely thereto as economically or technologically
feasible.
High and Intermediate
Risk Releases: For high and intermediate risk releases, soil contamination
must be remediated to the lowest of:
Residential or
industrial/commercial maximum soil contaminant concentrations, whichever
are applicable; or
Soil-to-groundwater
maximum soil contaminant concentrations.
Low Risk Releases: For
low risk releases, soil contamination must be remediated to the
residential or industrial/commercial maximum soil contaminant
concentrations, whichever are applicable.
