Engineering Certification "Roundup"

Recently, the PERCS Unit sent out letters to approximately 700 Permittees requesting updates for approximately 1,200 permits which our database shows do not have final engineering certifications, for permits originally issued between January 2010 to December 2015. We anticipate eventually following up on permits dating back to 2002.


If you have a permit for which you are unsure of the certification status, please use the Sewer Extension Permit Tracker link below to check our database for more information. Note that the review of responses to the letters sent out in May are taking approximately 10-15 business days due to the influx of responses.

Please direct any inquiries regarding this outreach project, including the submittal of certification documents and permit rescission requests, to Nyle Hothem at or (919) 707-9130.
