Certification Accreditation Tracking System (CATS)

If you are experiencing difficulties renewing a certification during this period, please email

Recertification is tracked through DEQ's Certification Accreditation Tracking System (CATS), an online self-service system used to re-certify Stormwater or Erosion certifications and to combine two of the same types of certifications into a dual certification (e.g. SWM Inspector & ESC Inspector into a Dual Inspector). Click here to access CATS.

Online Contact Hours


DEQ does not endorse nor recommend any specific online resources. However, a simple internet search of terms such as: “erosion online training”, “Virginia erosion webinars”, “stormwater webcasts”, "conservation webinars," or other such terms should generate training options. The determination on whether these online training events maintain, improve, or expand the skills and knowledge relevant to the certification being renewed is a decision for each certificate holder and subject to audit by DEQ.
