The monitoring organization has revised data from this monitor since the


most recent certification letter received from the state.

The certifying agency has submitted the certification letter and required


summary reports, but the certifying agency and/or EPA has determined


that issues regarding the quality of the ambient concentration data cannot


be resolved due to data completeness, the lack of performed quality


assurance checks or the results of uncertainty statistics shown in the


AMP255 report or the certification and quality assurance report.

The certifying agency has submitted the certification letter and required


summary reports. A value of "S" conveys no Regional assessment regarding


data quality per se. This flag will remain until the Region provides an "N" or


"Y" concurrence flag.

Uncertified. The certifying agency did not submit a required certification


letter and summary reports for this monitor even though the due date has


passed, or the state's certification letter specifically did not apply the


certification to this monitor.

Certification is not required by 40 CFR 58.15 and no conditions apply to be


the basis for assigning another flag value

The certifying agency has submitted a certification letter, and EPA has no


unresolved reservations about data quality (after reviewing the letter, the


attached summary reports, the amount of quality assurance data


submitted to AQS, the quality statistics, and the highest reported


concentrations).
