- Olin applies to DEP for various permits that will allow cleanup to begin. (See Residential Documents section)

Olin made the request because the remedy was based in part on some of the many proposed revisions to the Remediation Standard Regulations that were underway. The process to revise the Regulations has been delayed. Olin’s request, if approved, would keep progress toward implementing the cleanup DEP approved in the 2007 Remedy Selection Plan. Olin’s request is provided in a letter report titled: Evaluation of Compliance with RSR Criteria for Fill and Request for Alternative PMC and DEC Criteria, and Alternative Method for Demonstrating Compliance with DEC and PMC. (See Residential Documents section)
