As winter approaches, construction sites throughout New York State that are covered under NYSDEC SPDES General Permit (GP-0-20-001) may enter a temporary suspension of construction activity.  There is a specific procedure for temporary suspension of construction activity due to winter shutdown.

For construction sites where soil disturbance activities have been temporarily suspended (i.e., Winter Shutdown) and temporary stabilization measures have been applied to disturbed areas, the frequency of the Qualified Inspector inspections, and the resulting inspection reports, can be reduced to once every 30 calendar days.  It is noted that if straw mulch alone is used for temporary stabilization, it shall be applied at double the standard rate of 2 tons per acre, making the application rate 4 tons per acre.  Other manufactured mulches should be applied at double the manufacturer’s recommended rate.  Prior to reducing the frequency of inspections, the Owner/Operator must notify the NYSDEC Regional Contact, specified in the project specific SWPPP, in writing that the project has entered temporary suspension.  Refer to Standards and Specifications for Winter Stabilization, found on page 2.38 of the New York State Standards and Specification for Erosion and Sediment Control (NYSDEC Blue Book) for additional information pertaining to winter stabilization.

It is noted that weekly inspection must resume when soil disturbance activity restarts, or if a permit violation occurs during the temporary suspension period.
