The Abandoned Brownfield Cleanup Program

DEEP Audit and Closure Letter

  • Within 60 days of receipt of a site verification under the VRP Program (completion of remediation), DEEP will notify the eligible person/entity and DECD if a DEEP audit will be conducted.
  • Within 180 days of receipt of above verification, the DEEP will conduct the audit.
  • During the audit process, DEEP may request additional information. If the requested information is not received within 14 days, the 180-day clock for DEEP will be suspended until receipt of the information.
  • Within 14 days of completion of the audit, DEEP will provide the written audit findings to eligible person/entity, DECD and the licensed environmental professional (LEP) that issued the verification.
    • The audit findings will include approval (Audit Closure Letter) or disapproval of verification and if a disapproval notification is issued CT DEEP will include the reasons for disapproval.
  • The entity has 60 days from receipt of a disapproval to cure the deficiencies.
    • Within 60 days, the DEEP will issue a successful Audit Closure Letter (or a written disapproval with noted deficiencies).
  • DEEP may extend the review period beyond 180 days if it finds incorrect or misleading information in the submission, missing post-verification monitoring essential to the verification, insufficient remediation to prevent releases, absent records of environmental use restrictions included in the verification, or any legal violations relevant to the verification.
