prior to commencement of any land disturbing activity. The eNO1 form may be accessed at deq.nc.gov/NCG01.
Please direct questions about the eNOI form to the Stormwater Program staff the Raleigh central office. If the

North Carolina's Sedimentation Pollution Control Act is performance-oriented, requiring protection of existing
natural resources and adjoining properties. If, following the commencement of this project, it is determined that
the erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation
Pollution Control Act of 1973 (North Carolina General Statute 113A-51 through 66), this office may require
revisions to the plan and implementation of the revisions to ensure compliance with the Act.
Acceptance and approval of this plan is conditioned upon your compliance with Federal and State water quality
laws,regulations, and rules. In addition, local city or county ordinances or rules may also apply to this land-
disturbing activity. This approval does not supersede any other permit or approval.

Responsibility Form, which you provided. You are requested to file an amended form if there is any change in
the information included on the form. In addition, it would be helpful if you notify this office of the proposed
starting date for this project.

1. Avoid temporary stream crossings when possible. Attempt to complete the proposed construction

ensure protection of streams and other water bodies (see section 6.70 of the Erosion and Sediment Control
Planning and Design Manual).
2. Before the initiation of any construction related activity, revise the Financial Responsibility/Ownership
Form to include the deed book and page numbers of all properties in the project tract and submit copies of
these property deeds. Provide a copy of the final utility easement agreement or the landowner's signed and
dated written consent for the applicant to submit a draft erosion and sedimentation control plan and to
conduct the anticipated land disturbing activity.
3. Local government and other agencies may have additional requirements apart from 404 permitting and 401
certifications. Before the initiation of any construction related activity, submit all copies to this office of
any water quality certifications,buffer authorizations, or related permitting necessary to complete the
proposed construction.
4. Additional measures may be required- The applicant is responsible for the control of sediment on-site. If
the approved erosion and sedimentation control measures prove insufficient, the applicant must take those
additional steps necessary to stop sediment from leaving this site. [15A NCAC 4B .0115]
