On November 8, 2011, the Wilmington Regional Office received a plan revision for Stormwater
Management Permit Number SW8 091204. The revisions include the addition of a gravel drive,
paved area, sidewalk extension, and the reconstruction of a spill holding structure resulting in an
additional 5,258 square feet of impervious surface. It has been determined that a formal permit
modification is not required for the proposed changes. We are forwarding you an approved copy of
the revised plans for your files. Please replace the old approved plan sheets with the new ones
(SSW-1 and SSW-2).
Please be aware that all terms and conditions of the permit issued on December 23, 2009, remain
in full force and effect. Please also understand that the approval of this revision to the approved
plans for the subject State Stormwater Permit is done on a case -by -case basis, .Any other
changes to this project must be approved through this Office prior to construction. The issuance of
this plan revision does not preclude the permittee from complying with all other applicable
statutes, rules, regulations or ordinances which may have jurisdiction over the proposed activity,
and obtaining a permit or approval prior to construction.
If you have any questions concerning this matter, please do not hesitate to call me at [phone].
Sincerely,
