Dear Sir or Madam:

W. Cecil Worsley, Jr.

W. Cecil Worsley, III
President and CEO
In reference to NPDES Permit No. NC0065307, Worsley has determined that activities associated with the
referenced facility are classified under Standard Industrial Classification (SIC) Code 5500. Worsley does not
believe this SIC code is identified as any activity requiring a NPDES Permit for stormwater (i.e., oil/water separator,
outfall 002). This structure should not require monitoring due to the SCI Code for this facility.
Worsley respectfully requests your review of this matter as it relates to NPDES Permit NC0065307.
We appreciate your assistance in this matter. If you have any questions or comments, please do not hesitate to
contact me at the letterhead address or by telephone at [phone].
Sincerely,
RSLEY COMPANIES, Ir.,,

oil / water separator questions
Subject: oil / water separator questions
From: Charles Weaver <[e-mail]>
Date: Fri, 28 Dec 2007 13:57:39 -0500
To: Linda Willis <[e-mail]>
CC: Tom Belnick <[e-mail]>
BCC: Susan Wilson <[e-mail]>
Linda - if the facility that's currently unpermitted wishes to discharge the oil/water separator effluent to a
storm drain, they need an NPDES permit. If the source of the wastewater is from a petroleum site with
no solvent or non-petro contaminants, they could be covered under the General Permit for groundwater
remediations. I'll defer to Tom Belnick, as he did the 2006 renewal of the General Permit, for a final
word. The existing o/w discharges in Wilmington are mainly at oil storage facilities; that's why they
have individual permits.
As for the Dixie Boy truck stop [NC0065307], the 2007 permit renewal added an outfall [002] for the
o/w separator's discharge. However, 002's monitoring requirements do NOT include new parameters.
That permit took effect 8/l/2007. It is far too late for Worsley to "challenge" anything in the permit.
They had that opportunity when the draft was sent to Public Notice. If they want to request a permit
modification, they can; however, unless they have tied in the o/w separator to 001 it's unlikely we'll
change 002 on the permit.
