�_ Monthly and weekiv averaae effluent values. exceedances, and points for NH3:
Note: Limit exceedances are considered for monthly OR weekly averages but not both.
When a monthly average limit exists it will be used to detect exceedances and
generate points. This will be true even if a weekly limit also exists. When a weekly
average limit exists and a monthly limit does not exist, the weekly limit will be used
to detect exceedances and generate points.
