GROUNDWATER RULES PROPOSED REVISIONS (15A NCAC 02L .0202 & .0113)
 
On this page you will find information related to proposed revisions to the North Carolina Groundwater Rules.
 
Classifications and Water Quality Standards applicable to the Groundwaters of North Carolina are codified in Title 15A, Subchapter 02L of the North Carolina Administrative Code
 
Groundwater Quality Standards are mandated by North Carolina General Statue 143-214.1, which directs the Environmental Management Commission (EMC) to develop and adopt after proper study a series of classifications and water quality standards applicable to the groundwaters of the state. In addition, the EMC, on its own initiative or pursuant to a request under General Statute 143-215.3(e), may grant variances to the rules of Subchapter 02L (http://www.ncga.state.nc.us/EnactedLegislation/Statutes/HTML/ByChapter/Chapter_143.html).
 
PURPOSE OF RULE REVISION
The purpose of revising the 2L groundwater rules is to ensure that groundwater standards are established using the most recent U.S. EPA health effects information. These revisions were initiated by a rulemaking petition submitted by a representative for Rhodia, Inc., a global specialty chemical manufacturer that formerly operated as Rhone-Poulenc in Gastonia, North Carolina.
 
There are three rule change options proposed:
 
Option 1: A change in the 1,1-dichloroethylene standard from 7 ug/L to 350 ug/L is proposed in order to incorporate the most recent U.S EPA health effects information as published in the Integrated Risk Management System at http://www.epa.gov/IRIS/
 
Option 2: A change in the criteria used to establish a standard is proposed in order to allow the EMC to establish a standard less stringent than the federal maximum contaminant level (MCL) when the MCL is not established using the most recent U.S. EPA IRIS health effects information.
 
Option 3: A change in the variance procedure is proposed to allow the EMC to consider a request for a statewide variance from the groundwater rules and to make editorial corrections.
 
REQUEST FOR FURTHER COMMENTS
In addition, the EMC seeks other proposals that allow flexibility in implementation of 15A NCAC 02L .0202(d) while maintaining or achieving appropriate water quality and public health standards, recognizinf that any such proposal, if acted upon, might constitute a substantial change from the proposed rule amendments described in detail in this public notice, and might require an additional rule-making procedure.
