Footnote (b) is being added to clarify the timeframe for which the turbidity daily maximum is
evaluated.
Note that your interpretation for footnote (c) on Attachment A (regarding the sampling requirement for PPI
002) is correct,
Attachment -Approved Bulk Fill Reclaimed Water Uses
1. The phrase "not washing" associated with the sewer cleaning use is being removed.
2. The phrase "not street cleaning" associated with street sweeping is being replaced with phrase "not
