PRETREATMENT ANNUAL REPORT NCDEQ/DWR/NPDES
1 JAN 2019-31 DEC 2019
NARRATIVE:
During 2019 the Town of Williamston had no operational industries and therefore did not
administer any IUPs. We choose to keep our pretreatment program active in hopes that new
industries may locate here.No STMP data was gathered this year.
