• RCRA Corrective Action, Closure, and Stewardship

  Connecticut is authorized for RCRA Closure and Corrective Action, which requires facility owners and operators to clean up properties that have treated, stored, or disposed of hazardous waste. Information regarding financial assurance, ecological risks, RCRA closure, and various guidance documents.

• List of Contaminated or Potentially Contaminated Sites in Connecticut

  Information regarding contaminated sites or potentially contaminated sites in Connecticut.

• Remediation Forms

  List of Remediation Forms by Program.

• Removal from SEMS Potential Superfund List

  If remedial action has been completed through one or more DEEP Remediation Programs or an interested party has committed to remediate a site through a DEEP Remediation Program, DEEP can request that the Environmental Protection Agency (EPA) remove any active federal superfund site from the Superfund Enterprise Management System (SEMS), formerly CERCLIS or that EPA offer a "comfort letter" stating it will not take further action to list the site on the NPL.

• Federal Superfund Sites in Connecticut

  Information on the Federal Superfund sites in Connecticut.

• Superfund Programs

  Federal and State of Connecticut Superfund information

• State Superfund Program

  The State Superfund Program oversees and provides funding for the remediation of contaminated sites. The use of State funds for remediation at hazardous waste sites is determined by calculating a superfund priority score in accordance with Connecticut 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 and accepted public feedback regarding revisions to the Remediation Standard Regulations.

• Proposed Amendments to the Remediation Standard Regulations and Environmental Use Restriction Regulations

  The Remediation Division of the Bureau of Water Protection and Land Reuse is proposing amendments to Sections 22a-133k-1 through 22a-133k-3 of the Regulations of Connecticut State Agencies, the Remediation Standard Regulations (RSRs). The RSRs specify the standards for the remediation of environmental pollution in soil and groundwater.

• Remediation Standard Regulations Fact Sheet

  Connecticut's Remediation Standard Regulations (RSRs) provide detailed guidance and standards that may be used at any site to determine whether or not remediation of contamination is necessary to protect human health and the environment.

• Engineered Control Variances

  An Engineered Control is a permanent physical structure designed to safely isolate pollutants which would otherwise not comply with the self-implementing remedial options allowed in the Connecticut Remediation Standard Regulations (RSRs).

• Requesting APS and Alternative Criteria

  The Remediation Standard Regulations (RSRs), contain numeric cleanup standards for 88 substances. When a contaminant at a site is not one of the 88 substances, Additional Polluting Substance (APS) criteria must be approved by the Commissioner to complete cleanup at the site under the RSRs. When the RSRs contain criteria for a substance but a party believes different numeric criteria are appropriate for a specific site, that party may request approval of Alternative Criteria.

• Technical Impracticability Variance

  A Technical Impracticability Variance is a remedial option provided under the Connecticut Remediation Standard Regulations (RSRs) when non-aqueous phase liquids cannot be contained or removed in accordance with Section 22a-133k-2(g) of the RSRs, remediation to the extent technically practicable has reduced the concentration of pollutants in groundwater to steady-state concentrations, or as otherwise specified in EPA guidance.

• 1996 RSR Criteria Derivation

  The Remediation Standard Regulations that established the requirements for the remediation of contamination within Connecticut were organized by environmental media and relied, in part, on risk-based criteria that established remediation goals for various contaminants typically found at remediation sites.

• Remediation Standard Regulations

  Connecticut's Remediation Standard Regulations (RSRs) specify the standards for the remediation of environmental pollution in soil and groundwater.
