Subject: Stormwater Permit No. SW5090501
Murphy Oil USA — Siler City
High Density Commercial Sand Filter Project
Chatham County
Dear Mr. Heithaus:
Ded Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit
Application for Murphy Oil USA — Siler City on May 1, 2009, with additional information received
on May 13, 2009 and May 28, 2009. Staff review of the plans and specifications has determined
that the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A
NCAC 2H.1000 and Session Law 2006-246. We are forwarding Permit No. SW5090501, dated
May 29, 2009, for the construction, operation and maintenance of the subject project and the
stormwater BMPs. The approved design includes a sand filter that has been oversized to
provide additional treatment volume and surface area in lieu of providing an off-line bypass and
vegetated filter strip.
This permit shall be effective from the date of issuance until May 28, 2019, and shall be subject
to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system
for inspection and maintenance of the stormwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this
permit shall be final and binding.
This project will be kept on file at the Raleigh Regional Office. If you have any questions, or
need additional information concerning this matter, please contact Robert Patterson at (919)
807-6375; or robert.pattersonC@,_n_cdenr.gov.

Sand Filter Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a rJ.
t•
log in.a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity of CNI
structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
- The drainage area will be carefully managed to reduce the sediment load to the
sand filter.
- Once a year, sand media will be skimmed.
-- The sand filter media will be replaced whenever it fails to function properly after
vacuuming.
The sand filter will be inspected quarterly and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operatics and
maintenance will be kept in a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be

Permit No. SW5090501
Chatham County
Dear Mr. Heithaus:
On May 24, 2011, Lauren Witherspoon of the Raleigh Regional Office (RRO) of the Division of Water
Quality (DWQ) inspected the Murphy Oil USA — Siler City facility in Chatham County to determine
compliance with Stormwater Management Permit Number SW5090501 issued on May 29, 2009. DWQ
file review and site inspection revealed that the site had some deficiencies with the conditions and
limitations of this permit. These are listed below. Please address these deficiencies, describe your actions
in writing and, in addition, submit your operation and maintenance records to the DWQ Raleigh Regional
Office.
The sand appears to be too shallow based on the depth to filter fabric which is supposed to be 18"
below the sand media and -level with the top of the control weir retaining wall as depicted on the
approved WQv Treatement Plan (Sheet No. C-9) and Section I. No 7 (f) of the permit.
Erosion was observed around the weir which is not in keeping with the Sand Filter Operation and
Maintenance Agreement.
Trash/debris was present in and around the sand filter which is not in keeping with the Sand Filter
Operation and Maintenance Agreement.
Please be advised that you are required to comply with the terms, conditions and limitations of your
Stormwater Management Permit under Title 15A North Carolina Administrative Code 21-1 .1003 and
North Carolina General Statute 143-214.7, including operation and maintenance of your permitted
stormwater system.
If the project has changed name, ownership or mailing address, a formal change of name/ownership form
must be submitted to DWQ within 30 calendar days detailing the change. Please provide the name,
mailing address arid phone number of the person or entity that is now responsible for this permit.
Thank you for your assistance and cooperation in responding to these items. Please be advised that
violations of the Stormwater Management Permit may be subject to a civil penalty assessment of up to
$25,000.00 per day for each violation. If you have any questions, comments, or need assistance with one
