uua[cv REQUESTFORM
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 an icarl sampling requirements apply.
if Representative Outfall Staters is granted, ALL outfalls are still subject to the alaftfM monitoring
requirements of the facility's permit —unless otherwise allowed by the permit (such) as NC6020000) 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 reprosentative status.
For questions, please contact the DEQ Reglonal Office for your hrea 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.
We have pulled our data for the last several years and have had no changes. We have made all the changes we can make
to Improve these numbers, but still can not hit the target. We feel these numbers are unobtainable for our plant. The outfalls
will continue to be monitored and we will report any changes in the results. However, we think it would be best to only submit
results twice a year as discussed in our meeting. Our plant has stayed an top of testing the rainwater as well as frequent
visual inspections and will continue to do so. The visual inspections will continue at the same rate. We have a low risk of
contamination because of how our plant is set up and the precautions we have in place and continue to improve upon.
We request tier relief to Tier Three with sampling changed from monthly to semi-annual for outfall. Qualitative monitoring will
continue semi-annually for all five outfalls. We request outfall #2 to be the representative sample for ail five outfalls.
Historical data shows outfall #2 has been the highest of the five outfalls. In addition, if our sample results show any
significant changes in any of the quantitative metals tested, we will contact your office.
5) Certification:
North Carolina General Statute 143-215.6 B(i) provides that:

ten thousand dollars ($10,000).
1 hereby request Representative Outfall Status for my NPDES Permit. I understand that ALL outfalls are still
