In sire inspection reports for all risk level discharges, which weather information must be documented?

• A. Presence or absence of rain
• B. Est beginning of storm event, duration, and time since last event
• C. Approx amount of rainfall in inches
• D. All of the above

Answer: (D)

Documenting weather conditions in SIRE reports is essential because weather drives when discharges occur and how much runoff can be generated. For every discharge, you must record whether it is raining or not at the time; you should also estimate when the storm began, how long it lasted, and how long since the last event; and you need to note the approximate rainfall in inches. This full set of details gives a complete picture of the storm-driven context of the discharge, helps assess whether erosion and sediment controls were effective during a storm, and supports regulatory compliance. Each piece provides unique context—the presence of rain shows immediate conditions, the storm timing clarifies whether the discharge is during a storm event or post-storm, and the rainfall amount quantifies the potential contributing rainfall—so including all of them is the correct practice.
