Date Time TSS Concentrations October 14 7:30 a.m.
54 mg/L October 18 11:00 a.m.

^
Cause and period of the noncompliance--The exact cause of the noncompliances '
+
r is unknown. We suspect remodeling involving concrete dust, etc.,'jin' the
, ! J ', y !
sump area contributed excessive amounts of solids resulting in' the violations. The remodeling work has since ceased. Sample values indicated in the table show the possible duration of each noncompliance period was approximately nine days.
Steps taken to reduce, eliminate, and prevent recurrence of the noncomplying discharge--The sump was pumped out and cleaned on October 19 and 26 following each noncomplying sample to eliminate the excessive solids accumulation. Steps to control dust and other particulate matter during future remodeling work will be considered to prevent recurrence of this source of solids.
Sincerely,
