GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITH THE NCGO1
CONSTRUCTION GENERAL PERMIT
Implementing the details and specifications on this plan sheet will result in the construction activity being
considered compliant with the Ground Stabilization and Materials Handling sections of the NCGO1 Construction
p g
General Permit (Sections E and F, respectively). The permittee shall comply with the Erosion and Sediment
Control plan approved by the delegated authority having jurisdiction. All details and specifications shown on this
sheet may not apply depending on site conditions and the delegated authority having jurisdiction.

Note: After the permanent cessation of construction activities, any areas with temporary ground stabilization shall
be converted to permanent ground stabilization as soon as practicable but in no case longer than 90 calendar days
after the last land disturbing activity. Temporary ground stabilization shall be maintained in a manner to render
the surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the techniques in the table
below:
Temporary Stabilization
Permanent Stabilization
• Temporary grass seed covered with straw or
