At our net-positive pilot, we cut blower runtime about 12% by letting DO setpoints float off an ammonia probe, and for MSGP we wired the rain gauge to auto-start a log and email a PDF β€” β€˜measure once, never type twice’ (template: Stormwater Discharges from Industrial Activities | US EPA). Small caveat: auditors still want time-stamped field notes, so we keep a bound notebook as backup β€” anyone else doing this?

It’s interesting how tech can streamline processes; I’ve found integrating automated loggers has saved us a ton of time on audits… Still, @dporter71 brings up a good point about the auditors preferring that paper trail β€” those field notes really do help when they’re digging into details. Anyone tried combining manual and digital logging for the best of both worlds?
