On the morning of July 28,
2010, ten turbidity samples were collected in the sediment basin. The
turbidity readings were all close to the performance standard of 250 NTUs,
so the skimmer was flipped (9:00 am) to allow discharge from the
sedimentation basin. A turbidity reading was collected at the discharge
point shortly after discharge (9:08 am); the result was 752 NTUs, so the
skimmer was immediately flipped to stop discharge from the sedimentation
basin.
Additional flocculant material (Pond Clear) was then added again to the
sedimentation basin to assist with settling out the sediments from the
basin.
USEPA, PADEP, and Throop Borough were kept informed
on stormwater management activities during the period from July 19 to August
2, 2010.
A formal
non-compliance report
covering the period from July 19 to August 2, 2010 was submitted to PADEP on
August 4, 2010.
