In preparation for the new AQS Data Certification Report, a new monitor agency role of “CERTIFYING” has been created. This role specifies the agency that is responsible for certifying the monitor’s data. The certifying agency role has been initially populated based upon EPA Regional Office input. The following spreadsheets show the initial assignments made based upon Regional Office comment.

Precision data - AQS is no longer automatically generating precision data transactions during the load process; precision data for collocated monitors will be created on demand as needed for a report. Changes affect several reports.

- 255 Data Quality Indicator Report, 246 Precision Report, and 250 P/A Raw Data Report – precision data is now generated via a custom database view

- 502 Precision and Accuracy Data Extract - no change; shows only precision data loaded by a user via RP transactions
