The lecture is an integral part of the training for any visible emissions observer. The training provided in the lecture helps the visible emissions observer avoid the procedural and documentation errors that frequently result in invalid observations. For lecture you should dress comfortably and bring a couple of pens and pencils as well as a note pad. For the field session you should dress according to the weather. You could be outside the better part of two days.
Certification is valid for six months from the date of certification.
Certification must be renewed every six months. ETA provides schools in the same location every six months to meet this requirement. However, you do not need to return to lecture each year. It is a good idea to return to lecture every several years to learn about new items. You can also stay informed by occasionally checking this web site under the news.
