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.
