Strategies for complying with PM-10 and related air quality requirements
The Clean Air Act Amendments [CAAA] requirements have instituted stricter rules [implemented by the Environmental Protection Agency] to improve ambient air quality throughout the US. Powder processors are most affected by the CAAA provisions for particles with an equivalent diameter of 10 microns or smaller -- called PM-10 -- and air toxics. This article describes how to assess the type and quantity of your emissions so you can use prevention, containment, and capture strategies to meet PM-10 and air toxic emissions requirements. Later sections outline how to achieve critical emissions control and how to predict emissions levels when applying for an operating permit. Related information covers capturing PM-10 emissions from large, open sources and a summary of recent studies that link soot inhalation to thousands of deaths each year.
Major threats to the nation's air quality include particles with an equivalent diameter 10 microns or smaller [called PM-10] and the air toxics sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone, and lead. Other materials, such as heavy metals, many organic chemicals, carcinogens, mineral fibers, and radionuclides, are also considered toxic. Inhaling or ingesting any of these materials, or contacting them through the skin, can be hazardous to human safety and health.
