“(2) Establishment of a national network to monitor, collect, and compile data with quantification of uncertainty in the status and trends of air emissions, deposition, air quality, surface water quality, forest condition, and visibility impairment and to ensure the comparability of air quality data collected in different States and obtained from different nations.”
E4- Part of quality management focused of providing confidence that quality requirements will be fulfilled.
Another Definition- A system of activities whose purpose is to ensure that information derived from measurements are of a quality that the decision maker is willing to risk making an inappropriate decision.
Premise 1 - All estimates have error so all decisions made with estimates have risks.
Premise 2 - We can’t afford 100% certainty in our decisions
Some decisions will be inappropriate (wrong) due to data uncertainty…(error)
…the difference between
your measurement (estimate) and the “truth”

Example of QA/QC in daily life : Personnel Finances
Quality is Job 1
Must provide sufficient detail to show that:
QA and QC requirements based on:
Less Important Decisions
improving your program
Quality Systems for Ambient Air
Taking the overall EPA Requirements and bringing them into the Ambient Air Monitoring Program
Must be followed
Usually minimum requirements.. more is better
More details on regulations
Provides additional suggestions or strongly suggests
Are not mandatory, but you need an acceptable alternative

There is so much more to
QA beyond Appendix A
Other data quality indicators like comparability and representativeness are important, but since they relate to spatial/temporal variability or data outside the control of
a monitoring organization, they are not included in Appendix A.
Acknowledging that the quality control checks in Section 3 are required to be reported to AQS.
One exception- flow rate verifications (with the exception of automated PM10)
are not required to be reported to AQS. However, they can be reported if desired.
Each primary quality assurance organization shall be defined such that measurement uncertainty among all stations in the organization can be expected to be reasonably homogeneous, as a result of common factors. Common factors that should be considered by monitoring organizations in defining primary quality assurance organizations include, but all are not strictly necessary (see Region 5 and OAQPS PQAO guidance):
(a) Operation by a common team of field operators according to a common set of procedures;
(b) Use of a common QAPP or standard operating procedures;
(c) Common calibration facilities and standards;
(d) Oversight by a common quality assurance organization; and
(e) Support by a common management, laboratory or headquarters.
