January 31, 2023
It takes a team of staffers at the Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Air Quality Division to process permit applications.
Air Quality Division permit section staff reviewing documents.
Here’s a summary of their work in 2002:
Permits: Evaluating requests for air permits from companies is a big part of AQD’s work with industry stakeholders.
- AQD’s 15 Permit engineers evaluate hundreds of applications a year, tens of which go out for public comment.
- Technical evaluation of the rules and regulations that apply, as well as assuring any permit issued is protective of public health and the environment, can take time.
- Permit engineers don’t do this work alone, many other AQD staff work to provide robust and protective air permits.
Dispersion Modeling: AQD’s three air dispersion modelers use computer models to predict impacts of requested emissions as well as help review air models submitted by permit applicants.
- Provided modeling support for more than 88 permit actions.
Air Monitoring: AQD’s air monitoring staff help to provide information on ambient air quality around proposed facilities.
- Assist with approximately 20 permit actions a year.
Toxicologists: AQD’s four toxicologists also have a vital role in looking and requested emissions of toxic air contaminants.
- Toxicologists served as panelist in 18 permitting actions out for public comment.
- Toxicologist completed more than 357 screening level chemical reviews as requested by permit engineers for approximately 48 permit applications.
- Toxicologists conducted one multi-pathway risk assessment and three 226(d) site specific risk assessments.
Air inspectors: At least one of AQDs 64 inspectors provides feedback and information on every permit action.
