BMP Database• Streamline the process

When did we last inspect this BMP?

Why are we filling out the same information

three times?

Have you seen my inspection report?

Have all of the NOVs been addressed?

What inspections are due this month?

BMP DatabaseNine Mult i-Page Forms

Over 200 BMPs inspected annually

Future inspect ions will be pre-populated with

previous inspect ion’s data
