Fact Sheet on the New NCGO1 Permit
April2019
The NC Construction General Permit (also known as "NCGO1") was renewed on April 1, 2019. The updated permit
does not significantly change the measures that are required to. be impleme rated on construction sites. However,
there are some organizational and technical updates to the permit as descri bed below. Most notably, there is a new
process in which construction. sites will obtain official coverage under an NCGOI permit through an electronic
process. DEMLR worked with a broad team of stakeholders to make all of these updates. -if you have questions,
contact Annette Lucas at Annette. luca_s_ ncdenr.goy or [phone].
