The new National Pollutant Discharge Elimination System permit for construction activity becomes effective August 1, 2018.
Applicants who have applied for a permit prior to August 1, 2018, will be covered under the 2013 permit, but will need to complete the project within 18 months of that date or revise the stormwater pollution prevention plan for the project to reflect the requirements of the new permit.
