SI 436 - Lesson 4: Rationale for SO2 Monitor Siting Criteria
If you want to receive CEU credits for the course, you must be a Registered APTI user and will be required to provide a PIN upon passing the test. If you do not remember your PIN, contact Eric Crump. If you are a new user, it is recommended that you complete the Training Application Form at the beginning of the course, as it may take several days to process the application. If the PIN you select has already been used, we will notify you.
