How long are interference reports maintained for?

• A. 3 years
• B. 1 year
• C. 5 years
• D. 2 years

Answer: (A)

Interference reports are kept long enough to support investigations, track patterns over time, and meet compliance or audit needs. The three-year retention window provides a practical balance: it covers multiple occurrences and seasonal variations, so you can see if interference recurs and confirm trends, while still avoiding unnecessary long-term storage. Keeping reports for only one year may miss later developments or repetition, making follow-up harder. Five years, while longer, often isn’t required for routine interference documentation and adds storage costs. Two years doesn’t provide as much longitudinal context as three years does.
