Our Fall 2018 AQ101 Course is currently in-session.

Air Quality 101 (AQ101) Training provides a comprehensive and foundational knowledge of the Clean Air Act (CAA) and its various regulatory programs.  The course 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 course 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 is on a per-facility basis and provides access to live participation in the webinars, as well as the recorded content to rewatch at your convenience.*  AQ101 is offered as a complete course of 12 sessions.  Please see the syllabus below for details on each session.

AQ101 is $1500 per facility.

Dan Holland, Senior Consultant

Dan’s focus with ALL4’s AQ101 series involves sharing his 30 plus years of air quality experience, study, and knowledge with other air quality professionals. He 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.  Dan’s training style mixes lecture, chalk board examples, and survey questions that quickly fill up the hour session.
