How long must the owner or responsible person retain a copy of the report submitted to DEQ under the Soil Matrix Rules?

The requirement for retaining a copy of the report submitted to the Department of Environmental Quality (DEQ) under the Soil Matrix Rules is established to ensure that there is a clear and accessible record of all reports over an extended period. Retaining these reports for a duration of 10 years provides a balance that allows for sufficient time to address any potential follow-up actions or issues that may arise related to the soil contamination or remediation efforts. This time frame also aligns with many regulatory practices aimed at maintaining oversight and accountability in environmental management. By having access to these documents over a decade, owners or responsible persons can ensure compliance and provide necessary information if any queries or regulatory checks occur regarding the system and its management.
