How to read these columns
M&R complied is not a yes-or-no column. The agency records three values: Yes, in compliance, No-Major Violation and No-Minor Violation. Level complied is yes or no.
Both record what the agency determined for one monitoring period. The rows are in the agency’s own order, not ranked by either column.
