CAP Course for REPs Rescheduled for December 6

OPS will be providing the third offering of the Corrective Action Plan Preparation course on Thursday, December 6, 2018, starting at 9:00 am.

(This course was originally scheduled for October 17, but we have postponed it to December 6 to allow more time for people who need to take the course to sign up.)

The CAP Preparation course is a continuing education requirement for all Recognized Environmental Professionals (REPs), and both current and prospective REPs may attend. 

REPs who took this course in either September or October of 2017 do not need to take it again.

Space is limited, so sign up now!

If you have any questions, please contact Rob Herbert, Petroleum Remediation Supervisor, at 303-318-8543 or robert.herbert@state.co.us.
