How long must project records including SWM plans and registration statements be kept?

The correct duration for keeping project records, including Stormwater Management (SWM) plans and registration statements, is typically three years. This timeframe aligns with many regulatory requirements that aim to ensure accountability and allow for adequate review of compliance with stormwater permits and management practices.

After three years, the likelihood of needing these records for regulatory audits or enforcement actions decreases significantly, provided the project remained in adherence to applicable standards during that time. Retaining records for this period helps maintain a balance between ensuring sufficient documentation for regulatory oversight and managing the burdens associated with record retention.

While some options suggest longer retention periods, such as five years or indefinitely, these are not universally mandated and may exceed the necessary accountability for most projects. Similarly, retaining records for just one year may not be sufficient to cover the period in which inspections and potential disputes could arise. Thus, maintaining project records for three years represents a standard practice in compliance with regulatory frameworks.
