Stormwater containment system in All containment areas are regularly Physical condition of controls through
place, designed to handle peak daily inspected and maintained site observation (e.g. storm drains, storm
rainfall averages from the past 10 years pits, interceptors, basins)
(e.g. storm drain, storm pits) Maintenance plan includes when and
how stormwaters will be pumped out or Records of containment inspections and
released after rain events maintenance records check against plans
Record of last rain event along, check to
see if storm waters were pumped out,
check against written stormwater plan

Needs for secondary containments Materials (hazardous and non- Record of site’s material inventory list
are defined. Where required they are hazardous) assessed for potential and check requirement for secondary

container or 25% of the sum of all the secondary containments defined Record of preventive maintenance (PM)
containers (whichever volume is greatest) Secondary containments are regularly plan to ensure secondary containments
inspected and maintained including are included in the PM schedules, check
periodic water hold testing latest water hold test
Site walk-by observation, check condition
of the secondary containment (e.g.
corrosion, cracks, rainwater, debris,
compatibility of materials)
