Stewardship Permit

The Connecticut Department of Energy and Environmental Protection (DEEP) has released a Notice of Tentative Determination to issue a Stewardship Permit to Pharmacia & Upjohn Company, LLC, pursuant to Connecticut General Statutes (CGS) Sections 22a-6h and 22a-449(c), 22a-454 as applicable, and Section 22a-449(c)-110 of the Regulations of Connecticut State Agencies (RCSA).

Specifically, the Pharmacia & Upjohn Company LLC proposes post-remediation groundwater monitoring, continued operation of a groundwater treatment facility, and to maintain and continue the long-term care and monitoring of cover systems installed on the property. Upon issuance of the permit, the facility's interim status will be terminated and long- term environmental monitoring and maintenance obligations will be imposed. The proposed activity is not expected to adversely affect any natural resources or human health. The permit authorizes post-closure care and long-term maintenance and monitoring to ensure completed environmental corrective actions remain effective into the future.
