At a minimum, inspections shall be done weekly by the permittee (general contractor, developer or the developer’s designated representative), and within 24 hours after every storm or snow melt event large enough to result in runoff from the site (one-half inches or more in 24 hours). Date and amount of all rainfall events greater than one-half inch in 24 hours must be recorded. Rainfall amounts must be obtained by a properly maintained rain gauge installed onsite, a weather station that is within one mile of your location or a weather reporting system that provides site specific rainfall data from radar summaries. At a minimum, these inspections and rainfall recording shall be done during active construction (the MPCA has inspection forms available upon request).
