Only the Environmental Management Commission can designate groundwater classifications. •Clarified what documentation would be required of an applicant. •Specified that the designation is only for certain corrective action methods. •Risk-based •Areas of remaining contamination after approved termination of active corrective action •Where a variance has been granted 6 02L .0100 Re-Adoption •2L .0106 Corrective Action •Major reorganization but no substantial changes. •Retitled to “Initial Response, Site Assessment, And Corrective Action” for clarification. •Language reads more like a step-by-step process. •Moved monitoring and reporting rules to .0110 and .0111. 7 02L .0100 Re-Adoption •2L .0107 Compliance Boundary •Added that the compliance boundary shall remain in place for the duration of the permit. Currently, there is no specified timeframe for the termination of the compliance boundary. When the permit is rescinded or revoked, the compliance boundary goes away. •Introduced the concept of compliance zone for certain rules (the area between the compliance boundary and the waste boundary). Helps define that area without having to make references to the “area within the compliance boundary.” •Allowed multiple contiguous properties to be treated as a single property. Applied from General Statute 143-215.1(i). •For potential violations within the compliance boundary, eliminated the exception for limestones within the Coastal Plain to make it general for all bedrock. 8 02L .0100 Re-Adoption •2L .0108 Review Boundary •Specified that an exceedance of a Standard at the review boundary may require action. •Provided specific items that the Director may consider for requiring action. Examples •if the standards are exceeded by a very small margin, •concentrations are trending downward, or •for one-time exceedances 9 02L .0100 Re-Adoption •2L .0110 Monitoring •Moved monitoring requirements from .0106 to this rule. •Clarified that the Director may require additional monitoring of any constituent of interest (COI). For example, monitoring for a COI that could result from a geochemical change in the groundwater due to the presence of the system. •Added monitoring for surface water that has the potential to be impacted by groundwater. •Clarified a timeframe for the termination of monitoring programs. •If concentrations are at or below the standards for four consecutive quarters, the Director may issue a “No Further Action” letter depending on data trends. 10 02L .0100 Re-Adoption •2L .0111 Reports •Moved reporting requirements from .0106 to this rule. •Added some specific items to what is required in site assessment reports and corrective action plans. •These are items that are deemed necessary for complete and thorough reports. •Allow for easier evaluation by DWR staff. It should be noted that these items are generally provided by consultants when preparing these reports although they are not currently specified in the Rule. 11 02L .0100 Re-Adoption •2L .0112 Analytical Procedures •Referred directly to 15A NCAC 02H .0805(a)(1) which is the rule for laboratory procedures, analytical methods, sample preservation, sample containers, and sample holding times. 12 Action item Dates Finalize Fiscal Note In Progress RRC pre-review COMPLETE GWWMC Approval to Proceed to EMC July 2021 EMC Approval to Proceed to Public Hearing September 2021 Public Hearings October 2021 -November 2021 Compile Hearing Officers Report (HOR)December 2021 -March 2022 EMC for Final Decision May 2022 RRC for Final Review June 2022 -Sept 2022 Effective Date for Rule November 2022 02L .0100 Re-Adoption Timelines 13 Department of Environmental Quality Contact Information: Eric Smith Groundwater Resources Section NCDEQ Division of Water Resources (919) 707-3669 eric.g.smith@ncdenr.gov 14
