Qualified Inspectors

 

Our team receives a thorough and ongoing education. When they first start working at Tully Consulting Group, Stormwater Inspectors undergo 40+ hours of classroom and field training in our Tully University program. Once this initial training is complete, they begin working in the field under the oversight of their Project Manager and attend additional training to obtain their certifications.

From there, our team attends regular training sessions and participates in various workshops, including Dirt Time BMP Training, Industry Retailer Lunch-and-Learns, and more. All of our Inspectors have taken the required 8-Hour Caltrans WPCM Training and Title 22 Hazardous Waste Generator Training.

As soon as they’re eligible, our Inspectors acquire their QSP, QSD, and any necessary underlying certifications. Our entire team either has these certifications, or works closely with someone who does. Choosing us means you’re getting the best compliance guidance from trained professionals.
