Overview Introduction Investigation Remediation Standards Final Approval Covenant Not to Sue State Funding

Introduction –Elements of a successful “Brownfield” remediation project: Environmental conditions are clearly identified early in the redevelopment process Remedial actions to address environmental contamination are combined with the redevelopment of a site Potential for revisiting remedial actions is minimized

The Investigation Phase Comprehensive and thorough investigation: –Reduce long term liability –Provide more and better options for remediation Follow DEP Site Characterization Guidance Document –Develop a Conceptual Site Model –Communicate with DEP

The Investigation Phase Potential Funding for Investigations –Targeted Brownfield Assessments –Special Contaminated Property Remediation and Insurance Fund

The Remediation Phase Remediation Standard Regulations (RSRs) –Provide clear standards that allow remedial actions and costs to be quantified and budgeted –Allow remedial actions to be conducted simultaneously with redevelopment

The Remediation Phase The RSRs are risk-based and provide –Default criteria depending on the future land use and ground water classification –Alternative criteria and circumstances where criteria do not apply –Case by case approval by Commissioner for variances and exceptions

Final Approval Three programs to obtain a final approval that no further remediation is necessary: –The Property Transfer Program (Section 22a- 134) –Two Voluntary Remediation Programs (Sections 22a-133x and 22A-133y) Participation in these programs can also address concerns about federal liability

Final Approval The Property Transfer Act If hazardous waste was generated, stored or disposed after 1980, then any change of ownership triggers a requirement to investigate and remediate pollution DEP may defer approval to Licensed Environmental Professionals Changes in 1995 make process for compliance with the Act simpler

Final Approval Voluntary Program Under 22a-133x –Similar process to Transfer Act but voluntary approval can be delegated to LEP remedial action plan must be public noticed –Program can be used for any establishment under the Transfer Act or any site in a GA ground water classification

Final Approval Voluntary Program under Section 22a-133y –Process is entirely conducted by a LEP –Little or no DEP input unless LEP’s final approval is audited –Process is available to any site in GB ground water classification

The LEP Program LEP’s are: –Experienced and qualified private sector environmental professionals –Authorized to approve investigations and remedial actions in the Commissioner’s stead

Covenants Not to Sue A Covenant Not to Sue is an assurance that, once a site is remediated in accordance with RSRs, DEP will not require further remediation Two types of Covenants –Section 22a-133aa covenant (Type A) –Section 22a-133bb covenant (Type B)
