What this page shows

SWEETGRASS PHASE 7 is one of 399 storm water construction permits on EPA's NPDES register in Dorchester County, and it is among 43 NPDES permits in the Rantowles Creek subwatershed, this one included. Of all 399 such permits in the county, 79.9% carry an earlier issue date than this one, and none of the county's storm water construction permits with a violation on file is 0.0% of the group, so this permit has no violation on file either.
