- 7/10/2012Not all months have 30 days and not all quarters have 90 days. How will this affect compliance tracking?
- 7/10/2012Does the every 30 days mean 30 samples or one sample "every 30 days"?
- 7/10/2012 I’ve been working on the Stage 2 DBPR reporting form for our district, and am looking at the compliance calculation equations for operation evaluation levels (OELs) and locational running annual averages (LRAAs). I am taking into account the compliance calculation for systems that might miss monitoring at a location. For LRAA’s, the regulation specifies calculation of LRAAs based on the available data. For OELs, the regulation specifies a formula . If a system misses monitoring for any of the previous 3 quarters, would the OEL calculation use the available data also? Another alternative would be to not calculate OELs when there is missing data. Otherwise, the OEL calculation would be biased low.

- 7/10/2012For Schedule 1 systems that use existing Stage 1 sites for Stage 2 compliance, does the LRAA MCL compliance begin-date start in 2nd Quarter 2012, or after 4 quarters of monitoring, same as for the new Stage 2 sampling locations?
