Air Emission Control Technology Frances A. Hardrick We Energies UWM Air Pollution Meteorology Class November 20, 2007
Overview • Air Emission and Monitoring • Project Specifics • Careers
CEM in General Terms • Continuous Emissions Monitoring (CEM) • Sample the Flue Gas - One of Two Ways • Measure Directly at the Stack or Duct • Extract Sample and Transport to Analyzing Equipment • Log Results Electronically • Store Data for Historical Record
What Drives Improvement? • We Energies Emission Controls Influenced by Environmental Commitment and Governmental Regulations • EPA Clean Air Act 1963/1970/1990 • Consent Decree 2003 • Performance Specification 11 (PS-11) 2004 • Clean Air Mercury Rule (CAMR) 2005
Clean Air Act • EPA Clean Air Act 1963/1970/1990 • Sets Limits on Air Pollutants • Approves Plans for Reducing Air Pollutants • Assists in Supporting Clean Air Progress
Consent Decree • Agreement to Significantly Reduce Air Emissions From Coal-Fueled Plants • Nitrogen Oxide (NOX) • Sulfur Dioxide (SO2) • Particulate Matter (PM) • Mercury (Hg) which was optional
PS-11 and CAMR • Finalized Specifications and Test Procedures for Particulate Matter Continuous Emission Monitoring Systems (PM CEMS) at Stationary Sources • Finalized Clean Air Mercury Rule (CAMR) and Specification and Test Methods for Total Vapor Phase Mercury CEMS in Stationary Sources
