What This Document Is
These are lecture notes from CEEN 302, Fundamentals of Environmental Engineering at Colorado School of Mines, specifically covering the topic of air pollution. The material introduces the major types of air pollutants – both primary and secondary – and the historical context of air quality regulation in the United States. It frames air pollution as a significant environmental challenge, emphasizing the increasing visibility of atmospheric haze.
Why This Document Matters
This document is essential for students in environmental engineering programs, and anyone seeking a foundational understanding of air quality issues. It’s used early in a course to establish the scope of the problem and the regulatory framework designed to address it. Understanding the origins of pollutants, the Clean Air Act, and the NAAQS is crucial for subsequent study of pollution control technologies and environmental impact assessment.
Common Limitations or Challenges
This document provides an overview and does not delve into detailed modeling of atmospheric dispersion, specific control technology designs, or the complexities of international air quality agreements. It’s a starting point, not a comprehensive resource. It also focuses heavily on the US regulatory landscape.
What This Document Provides
The full document includes:
* An overview of industrial (sulfurous) and photochemical smog.
* A list of the six principal pollutants regulated under the Clean Air Act (CO, NOx, SOx, Pb, O3, and PM-10/2.5).
* A discussion of primary and secondary pollutant formation.
* Details on the Clean Air Act, including NAAQS, SIPs, and NSPS.
* An example of how the Clean Air Act has been amended and challenged (the 2016 methane rule).
* An explanation of compliance with NAAQS and the Pollutant Standards Index (PSI).
* A discussion of Prevention of Significant Deterioration (PSD) classifications for air quality.
This preview does *not* include detailed chemical reactions, specific emission control strategies, or in-depth case studies. It does not provide calculations or solutions to any problems.
