Course Description:
The rapid growth of tribal air quality programs has created a need for tribal personnel to adequately manage air quality data and report data in the proper format to U.S. EPA’s Air Quality System (AQS). This course is intended to enhance tribal capacity in air quality data management and reporting.

Topics include:
  • Components of AQS

  • Site registration

  • Standard reports

  • Data formats

  • Posting raw data

  • Correcting data in AQS

  • Live loading of data

  2. Submitted a draft Quality Assurance Project Plan (with a Network Design Plan) to EPA.

  3. Begun monitoring and collecting data for at least one criteria pollutant or for meteorological conditions.

  4. Provided example monitoring data to ITEP.
