MRF Update – Audits
Patterns: – Not reporting all disturbances created or used over the life of the tenement
– Reporting sections of land as both disturbed and under rehabilitation
Reassessments
Each tenement audited at least once every 5 years
– Audits can include the previous 2 years of reporting
