For how long must owners/operators maintain site closure assessment records?

Owners and operators must maintain site closure assessment records for a duration of three years following the closure of a facility. This requirement is rooted in regulatory measures to ensure that comprehensive documentation is available for review in case of any future environmental concerns or liabilities that may arise from past operations. Retaining these records for three years allows for adequate oversight and facilitates the investigation of any potential contamination issues that could have long-term implications on public health and the environment.

The three-year retention period aligns with similar regulatory guidelines which aim to balance the need for accountability with practical considerations for record-keeping. This time frame ensures that if any issues or assessments regarding site closure are needed within a suitable period after operations cease, the necessary documentation can be accessed readily, ensuring compliance with environmental statutes and protecting the public interest.
