Re: NPDES Stormwater NO EXPOSURE Certification for Exclusion (NCGNEOOOO)
Approval Request
Braven Environmental, LLC
517 N. Industrial Dr.
Zebulon, Wake County,North Carolina 27597
CPEES Prolect No. 1202-001
Dear Ms. Cook:
Based on my discussions with Mr. Mike Lawyer,NC DEQ-NPDES Permit Supervisor,on behalf of
Braven Environmental,LLC(Braven)located at 517 N. Industrial Dr.,Zebulon,North Carolina, CP
Engineering and Environmental Solutions(CPEES)is pleased to submit the attached Stormwater NPDES
No Exposure Certification for Exclusion(NCGNE0000)request for the subject facility operations. The
facility manufactures liquid petrochemicals using waste plastics via pyrolysis method and the generated
products are stored on site in an aboveground storage tanks contained in a concrete dike. The operations
are conducted under SIC/NAICS Code 2869/32511"Petrochemical Manufacturing". Based on my
conversations with Mr. Mike Lawyer, I understand that if the petroleum tanks are contained in a
dike and no other industrial activity is exposed to rain water, the facility could apply for a No
Exposure Citification for stormwater discharges at the subject facility. In addition, we had
installed an Oil/Water Separator to remove oils below the State standards using oil coalescing
screens.
We intend to discharge the dike stormwater through the proposed oil/water separator from the
facility to the outfall as deemed necessary. All collected oils from the oil/water separator will be
either recycled in the plant or disposed of properly using a licensed disposal contractor. The
outfall location with lat/long is provided on the Site Drainage Map.
The Stormwater NPDES No Exposure Certification for Exclusion(NCGNE0000)Application
package includes:
• A signed NC DELMR supplied NCGNE0000 NOI application;
• Process Flow Diagrams and proposed Oil/Water Separator installation details:
• USGS TOPO Map;
• Site Drainage Map showing the proposed Oil/Water Separator location;
• Site Drainage Map showing the location of the outfall from the facility; and
• TMDL and 303(d)Maps.

No Exposure Certification for Exclusion
NCGNE0000
Submission of this No Exposure Certification constitutes notification that your facility does not require a permit for
stormwater discharges associated with industrial activity in the State of North Carolina because it qualifies for a no
exposure exclusion.A condition of no exposure at an industrial facility means all industrial materials and activities
are protected by a storm resistant shelter (with some exceptions) to prevent exposure to rain, snow, snowmelt,
and/or runoff. Industrial materials or activities include, but are not limited to:
• material handling equipment or activities, • by-products,
• industrial machinery, • final products, or
• raw materials, • waste products.
• intermediate products,
Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product,final product, or waste product.
A storm resistant shelter is not required for industrial materials stored in the following container types, provided
the containers are not deteriorated and do not leak:
• drums, • tanks,and
• barrels, • similar containers.
For new facilities, applicants should apply no earlier than 60 days before the start of operation. This will allow
DEMUR staff to verify conditions during active operation. For facilities that already have an industrial stormwater
permit in North Carolina, DEMLR must approve your application for No Exposure Certification before this exclusion
is effective. Until you are issued a No Exposure Certification and your NPDES permit is rescinded,your facility must
continue to abide by the terms and conditions of the current permit.
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion.Additionally,
the exclusion from NPDES permitting is available on a facility-wide basis only — not for individual outfalls. If any
industrial activities or materials are,or will be,exposed to precipitation,the facility is not eligible forthe no exposure
exclusion. By signing and submitting this No Exposure Certification form,you certify that a condition of no exposure
exists at this facility or site and are obligated to comply with the terms and conditions of 40 CFR 122.26(g).
For new facilities, applicants should not apply more than 60 days before the start of operation date. This
If approved, your conditional No Exposure Certification has no expiration date but must be self-recertified at least
annually. Please look for information about recertification under the No Exposure section on this page:
https://deg nc gov/about/divisions/`energy-mineral-land-resources/npdes-no-exposure.
Directions: Print or type all entries on this application form. Send the original, signed application to: NCDEMLR
Stormwater Program, 1612 MSC, Raleigh, NC 27699-1612. The submission of this form does not guarantee
exclusion from NPDES stormwater permitting. Prior to exclusion from NPDES stormwater permitting a site
inspection will be conducted.

Installation, Operation and Maintenance Instructions for above grade models
(SA-HF-SS-300)
Installation:
1. Locate separator at desired location using the supplied lifting lugs.
2. Inlet Pipe-Attach to waste water source.
3. Outlet Pipe-Attach to discharge.
4. Oil Outlet Pipe-Attach to oil storage tank or install shut-off valves.
5. Drains- Install shut-off valves and/or pipe back to sump pit.
6. Install anchors using the supplied anchor bolt location drawing.
Operation:
1. Fill unit with clean water.
2. Introduce waste water stream at or below the separators rated flow rate per minute.
3. Rotate oil skimmer to a vertical position.
4. Oil will accumulate at the surface.
5. Clean water will pass thru the unit to the discharge pipe.
6. Solids will fall to the bottom of the inlet chamber as well as under the coalescers in the
- ---separation-chamber. — —
Maintenance:
1. Remove oil layer by rotating skimmer pipe open area towards oil. Remove excess oil
only to avoid removing clean water. Minimum oil level build up prior removal %_" or
approximately 15 gallons. Maximum oil level build up before affecting the separation
process is 4 inches or approximately 120 gallons.
2. Check for solids build up.
A. Rotate vertical fiberglass angles upward to remove front horizontal hold down angle.
B. Remove front horizontal hold down angle.
C. Remove center bundle from the first row and check to see if there are solids in the
bottom portion of the bundle.
D. If solids are present it is time to remove the coalescers and clean.
E. Remove grating and the solids from the bottom of the separator.
F. Reinstall grating, coalescers and hold down angle.
G. Fill unit with clean water. Unit is now ready for operation.
