All BMP's/SCM's that were inspected from October 2017 — January 2018 were given a 1 year extension with the new O&M agreement, as they just recently passed their devices. Then those reports are given to Stormwater Staff for a follow up inspection to make sure the report is correct. Clemmons staff have 30 days from when they receive the 3rd party inspection report to follow up and then agree or disagree with the report. If Village Staff finds an area was missed, they contact the 3rd party consultant and the owner of the BMP to fix any necessary items listed within 30 days, or then the BMP owner is considered non -compliant and fines can start to be issued. All finished BMP's were inspected by 3/31/20.
