The following is the renewal package for NCS000520. As preferred a copy of this package has been e-
mailed to [e-mail] as the second copy. Included in this package are the following
items:
• Cover Letter
• EPA Form 1 NPDES
• Topographic Map
• Signatory Authority Letter

• Supplemental Information Required for Renewal of Individual NPDES SW Permit
Outfall 200 is sampled from Drop inlet #201 (see Outfall 100 and 200 Drainage Areas Drawing). Please
note that the invert of this Drop Inlet is -2.4. At this elevation seawater will be present resulting in a non-
representative sample of the discharge. This drop inlet is the only one in which stormwater from the north
and south sides of the western end of the Phosphate Storage Warehouse are combined prior to discharge.
Due to these physical conditions a representative sample of the discharge is not possible, and we therefore
request that the requirement to sample Outfall 200 be removed from the permit.
Please do not hesitate to call me at 252-322-8263 should you have any questions concerning this.
