Connecticut Remediation Standard Regulations
Wave 2 Revision Concepts and History

The Department of Energy and Environmental Protection (DEEP) presented proposed concepts in the RSR Wave 2 Conceptual Language document, as well as at multiple question and answer sessions in April 2016, and accepted public feedback through May 6, 2016.  Based on the external comments provided to DEEP and internal review of the April 2016 RSR Wave 2 Conceptual Language document, the Revised RSR Wave 2 Conceptual Language document was generated in August 2016.
 

RSRs "Wave 2" Draft Discussion Documents

 
As a basis for future amendments to the RSRs, the Department developed “public discussion drafts”, the purpose of which was to provide more detail to the concepts set forth in the November 2012 Cleanup Transformation and Evaluation Workgroup reports and the February 2013 Cleanup Transformation report:  

Risk-Based Decision Making Report 

DEEP's "Risk-Based Decision Making Recommendation Report", dated April 15, 2015, was prepared in accordance with Section 28 of Public Act 13-308. The Public Act, passed on July 12, 2013, charged DEEP, in consultation with the Department of Public Health (DPH), to evaluate the risk-based decision making processes related to the remediation of contaminated sites in Connecticut.  DEEP summarized this report at a presentation to the public on April 28, 2015. 

DEEP's report is based on its review and analysis, in consultation with DPH, of CDM Smith's report dated August 29, 2014  “Evaluation of Risk-Based Decision Making”, the public comments on CDM Smith's report, and DEEP's own research.  While many aspects of Connecticut's risk-based decision making are consistent with other states and reflect "best practices," DEEP's report contains recommendations for improvements in three areas:

  • Ecological risk assessment and management,
  • Updating numeric criteria, and
  • Risk-based flexible remedy options.
