Smoke School

EPA Visual Emission Testing

Schedule

Our fall 2025 schedule is listed below. Re-certification is available at all events. Please check each event listing for initial certification availability. Click on the name of each location for driving directions.

Initial certification attendees will need to arrive before 8:15 am for equipment orientation. Students will test from 9:00 am to 2:00 pm and will receive a manual with an access code for the online lecture to be completed.

Re-certification testing starts promptly at 9:00 am on all dates (including days where we provide initial training). On all days where initial training or re-certifications is provided hours are 9:00 am to 2:00 pm.

If you plan on arriving late, we ask that you make prior arrangements. If delayed on event day, call to make sure we're still testing. Once everyone has completed testing, we leave. Also if you have registered late, (less than 1 week in advance), please call to notify us as we will not have access to that information.

On 2 day events if we run into a situation where we are not aware of anyone attending, and no one shows by 9:30 am, we will move on to the next location. Be sure to remain in contact with us.

Registration: Registration and payment of fees should be completed at least 7 days prior to the event. Once an observer is registered, they may attend any of the subsequent testing events in the same season (Spring or Fall). This avails all dates to observer. Online registration is preferred and encouraged. Major credit cards accepted.*

On-Site Registration: On-site registration is available, but we prefer online enrollment. Registration must be paid (or signature authorizing payment) prior to the start of testing. If you are choosing to arrive after 10:00 am, please call before 10:00 am.

*Credit Card will be charged a 3.4% convenience fee.
