Representative Outfall Status (ROS) Request
Greenheck Fan Corporation COC: NCG030706
1001 Commerce Center Drive
Shelby, NC 28150
To Whom It May Concern:
On behalf of Greenheck Fan Corporation, please find the enclosed "Representative Outfall Status
(ROS) Request Form," two (2) copies of the facility site map, and a summary of monitoring results
table to request ROS analytical sampling at Outfalls #2 and #3 at the property. The sampling evidence
provided confirms all drainage areas are below benchmark parameters.
The facility is regulated under General Permit No. NCG030000 "Metal Fabrication." Three (3)
drainage areas with corresponding outfalls are present at the property (see enclosed site maps). No
TMDLs or impairments are noted for the associated receiving waterbody beyond a statewide TMDL
for mercury contaminated fish tissue.
The majority of stormwater exposures are contained within drainage areas #2 and #3. There are no
observed industrial exposures in Drainage Area # 1. Potential exposures within Drainage Area #2
include:
1) Erosion,
2) Trailer storage, and
3) Wood pallet storage.
Potential exposures within Drainage Area #3 include:
1) Erosion,
2) Wood storage,
3) Dumpster storage, and
4) Loading dock areas.
Drainage Area # 1 serves only as employee parking and is ancillary to associated industrial activity.
The parking area is paved and surrounded by manicured grass. We are requesting ROS for Outfall
#2 (Drainage Area #2) and Outfall #3 (Drainage Area #3) since all industrial activity occurs within
© REI Engineering Inc. P:\9000-9099\9000 - Greenheck EHS\North Carolina\Shelby\BGNC TAP (Former Schletter)\Storm Water\Representative Outfall Status\9000NCTAPROS.docx

these drainage areas and would be representative of the true industrial stormwater exposures at the
site.
A summary of monitoring results table is enclosed. The sampling event conducted on February 13,
2020 for all three outfalls demonstrated all measured parameters are within benchmark values. This
has been the only sampling event to date.
In summary, we are formally requesting analytical sampling requirements for Outfall #2 and Outfall
#3. Outfalls #2 and #3 represent stormwater runoff from all industrial activities at the site. We
request that analytical sampling is waived for Outfall # 1. All other permit requirements would apply
to Outfall # 1.
Please feel free to contact me with any questions at [phone]. A copy of this request has also
been emailed to Suzanne McCoy at suzanne.mccoy_&ncdenr.gov as directed by your website.
Sincerely,
REI Engineering, Inc.

Environmental REPRESENTATIVE OUTFALL STATUS (ROS)
Quality REQUEST FORM
FOR AGENCY USE ONLY
Date Received

Da
If a facility is required to sample multiple discharge locations with very similar stormwater discharges, the
permittee may petition the Director for Representative Outfall Status (ROS). DEQ may grant Representative
Outfall Status if stormwater discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply.
If Representative Outfall Status is granted, ALL outfalls are still subject to the qualitative monitoring
requirements of the facility's permit —unless otherwise allowed by the permit (such as NCG020000) and DEQ
approval. The approval letter from DEQ must be kept on site with the facility's Stormwater Pollution
Prevention Plan. The facility must notify DEQ in writing If any changes affect representative status.
For questions, please contact the DEQ Regional Office for your area (see page 3).

Representative Outfall Status Request
4) Detailed explanation about why the outfalls above should be granted Representative Status:
(Or, attach a letter or narrative to discuss this information.) For example, describe how activities and/or
materials are similar.
See letter
5) Certification:
North Carolina General Statute 143-215.6 B(i) provides that:
Any person who knowingly makes any false statement, representation, or certification in any application, record,
report, plan, or other document filed or required to be maintained under this Article or a rule implementing this
Article; or who knowingly makes a false statement of a material fact in a rulemaking proceeding or contested case
under this Article; or who falsifies, tampers with, or knowingly renders inaccurate any recording or monitoring device
or method required to be operated or maintained under this Article or rules of the [Environmental Management]
Commission implementing this Article shall be guilty of a Class 2 misdemeanor which may include a fine not to exceed
ten thousand dollars ($10,000).
I hereby request Representative Outfall Status for my NPDES Permit. I understand that ALL outfalls are still
subject to the qualitative monitoring requirements of the permit, unless otherwise allowed by the permit
and regional office approval. I must notify DEQ in writing if any changes to the facility or its operations
take place after ROS is granted that may affect this status. If ROS no longer applies, I understand I must
resume monitoring of all outfalls as specified in my NPDES permit.
I certify that I am familiar with the information contained in this application and that to the best of my
knowledge and belief such information is true, complete, and accurate.
