About AQ101

Air Quality 101 (AQ101) Training provides a comprehensive and foundational knowledge of the Clean Air Act (CAA) and its various regulatory programs.  The program covers the history of the CAA, National Ambient Air Quality Standards (NAAQS), and an overview of regulatory programs that impact industrial operations (e.g., New Source Performance Standards, Prevention of Significant Deterioration, air quality modeling, etc.).  The program also covers more focused topics that are encountered day to day by facility environmental personnel such as the basics of emissions testing and continuous emissions monitoring.

AQ101 is ALL4’s training for employees with no or limited experience in the field of air quality.  It may also be helpful for professionals with experience in a specific sub-discipline of air quality who are looking to expand their knowledge.

AQ101 is training for those seeking to establish and further their understanding of air quality obligations that impact regulated facilities on a day to day basis.  The topics covered by AQ101 will be encountered by environmental personnel in their real world projects.  Unlike other air quality training programs, AQ101 is delivered via twelve 1-hour webinar sessions, so no out of facility time is required for AQ101 participation.

Numerous professional designations require continuing education/professional development.  Upon request, ALL4 will present a certificate identifying ALL4’s Air Quality 101 as 12 hours of continuing education/professional development.  Many states and professional organizations accept continuing education hours/professional development hours for license/certification renewal purposes.  To ensure acceptability in each personal situation, please check with the requirements of your State Board/Professional Organization.


Registration for AQ101 is on an individual user basis.  Each user has access to live webinars and the recordings after each session.  Discounts are available for groups of 4 or more.

AQ101 is $950/user
Groups of 4-10: $893/user
Groups of 11+: $836/user

Lindsey Kroos, Technical Manager

Lindsey believes that having more than a cursory understanding of the history and intent of air quality regulations enhances how facilities incorporate those regulations into their daily business routines.  Being smart about regulations that direct how to permit, demonstrate compliance, monitor, and track air emissions provides a competitive advantage to the air quality professional and, at the very least, puts him/her on equal footing when interacting with regulators.  During AQ101, Lindsey engages in dialogue with other ALL4 experts on foundational air quality topics, and incorporates examples, survey and poll questions, and other interactive methods that quickly fill up each hour session.
