Salisbury Street, 9th floor 1612 Mail Service Center Raleigh, NC 27699-1612 Preface: This document has been filled out/written with the context of the changes made or in the progress of being made in the time between the initial NCDEQ MS4 Audit (10-22-2019), and the time this self -audit will be reviewed by the NCDEQ. The majority of the responses focus on the modifications to the Draft SWMP and the Best Management Practices the City uses. If a status is marked as 'Not Reviewed' this is due to it being found previously acceptable according to the NCDEQ Audit. The City has contracted the Western Piedmont Council of Governments to assist in bringing their stormwater program into compliance with the shortcomings found during the MS4 Audit. The Draft SWMP will be finalized and submitted to NCDEQ prior to the 2-28-2020 deadline.
