Lecture

The lecture is focused on the essential requirements of the Method with a brief review of the history, science and legal aspects. The majority of the lecture focuses on the how to perform a Method 9 reading and properly document the results.

History of Visible Emissions and Air Pollution Control
A brief history of visible emissions control in the United States.

Legal Aspects of Visible Emissions Use and Certification
Discussion about why accurate visible emissions readings are so important. We cover the advantages and limitations of visible emission readings. We provide resources regarding Method 22, Method 203A, 203B, and 203C, and the use of cameras.
10 Minute Break, resume approximate 9:30

Sources of Visible Emissions
There are several sources of emissions that one may come across in their career. Sometimes sources of emissions may be surprising. We explain different emission sources and how they behave. We guide you on selecting the correct observation method – Method 9, which is the major method used, Method 22, Method 203A, 203B, and 203C. We will briefly cover the less-used methods in order to completely prepare students to read all emission sources.

Types of Control Equipment
There is a wide variety of emission control equipment and their efficiency and effectiveness can be monitored with visible emission observation (VEO) methods. We will discuss the advantages/disadvantages of the various control equipments and the use of cameras. This overview helps you to understand how to document and utilize your results to achieve compliance to the air pollution control laws.

Theory and Science
This lays the foundation of understanding Method 9 and explains the statistics, physics of light scattering and other factors that affect emissions observations.

30 minute break or work through lunch if class is running late

Method 9 Observation Form
Using the form provided, attendees will complete a visible emission observation form (VEO form). We will discuss the how and why of the data and how to obtain the data. Included is a detailed demonstration of tools which may be used to collect the required information. In this discussion, we cover water vapor plumes in brief, special reading problems, and the how, why and when to correct for a slant angle.

Lecture Test
The lecture test will document that the attendee has obtained the information needed to understand and pass their certification.

The lecture course wraps up with the certification process video as the instructor grades lecture tests and issues certificates for attendance at the lecture. The attendees learn what to expect during field certification.
