Dear Ms. Gibson:
The Division has reviewed your submittal of the No -Exposure Certification form for Exclusion
from NPDES Stormwater Permitting. Based on your submittal and signed certification of no
exposure at the above referenced facility, and the inspection dated October 24, 2016, the
Division is granting your conditional exclusion from permitting as provided for under 40 CI+R
122.26(g), which is incorporated by reference in North Carolina regulations.
Please note that by our acceptance of your no -exposure certification, you are obligated to
maintain no- exposure conditions at your facility. If conditions change such that your facility
can no longer qualify for a No -Exposure exclusion, you are obligated to immediately obtain
NPDES permit coverage for your stormwater discharge. Otherwise, the discharge becomes
subject to enforcement as an unpermitted discharge.
You must self re -certify your No -Exposure status annually using the included form or obtain
NPDES permit coverage for any stormwater discharges from your facility. The annual self re-
certification does not need to be submitted to DEMLR unless requested.

NO EXPOSURE:
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, andlor runoff.
For permitted facilities 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Exposure Certification and your NPDES permit is rescinded, your facility must continue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.
industrial materials or activities include, but are not limited to: material handling equipment or activities,
industrial machinery, raw materials, intermediate products, by-products, final products, or waste 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 the following industrial materials and activities: drums, barrels, tanks, and similar containers
that are tightly sealed, provided those containers are not deteriorated and do not leak. "Sealed" means
banded or otherwise secured and with locked or non -operational taps or valves; adequately maintained
vehicles used in material handling; and final products, other than products that would be mobilized in
storm water discharges (e.g., rock salt).
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In
addition, 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 for the 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).
If approved, your conditional No Exposure Exclusion has no expiration date
BUT MUST BE self re -certified at least annually.
Please look for information about re -certification under the No Exposure section on this page:

Welcome back! Hopefully, you are back on USA sleep time. It always took me a couple of weeks. Attached
are the items that you requested. As you will see during your visit the plant is doing a great job but to no
avail. In the meanwhile I am still looking for a plant description. I will send it as soon as I receive it.
I am looking forward to meeting with you and Stan... and enjoying the weather. It was 13 here this

Timkin Co.
The Timkin Co. is not in a tiered sampling situation. They exceeded the Cu benchmark in May 2016 only — so no tiered
sampling criteria are met. Under the new benchmark, which they will receive in their renewed permit, they would not
have exceeded. Current benchmark is .007 mg/I and the new benchmark is .010 mg/I. They consistently get <.005 mg/I
Cu.
We can still conduct an inspection since it appears they have never had an inspection or even a site visit. But there
really are no issues to be addressed based on their monitoring. They only monitor 3 outfalls, and maybe they can apply
for ROS but we can assess that also.
have all the info we need to meet with Dominic.

Thanks. So they only hit the levels of the new benchmark in May and have previously been below the benchmark except
on a couple of occasions since 2013. It seems the guy that called is overreacting, but we will meet with him and do an
inspection and provide guidance, since it appears they have never been inspected or had a site visit before.
I will let you know what we find.

Darlene,
There were some DMRs scanned into Laserfiche. You can access them from the Guidance Documents intranet page
here:
http://portal.ncdenr.orglgroupllr/stormwater-guidance
Look at the TOP for the link to Laserfiche (see screen shot below), and then navigate to the folder for this COC#.

We've had to put scanning on hiatus because it's just too much for Laura and our group right now, especial) not that
g Y
we're down two staff + a supervisor. So, there could be more recent DMRs that aren't there.
The benchmarks are in the General Permit NCG03 on-line (see here), but the Cu and Zn benchmarks will be revised to
the current ones, which are:
Cu — 0.010 mg/1 (small change)
Zn — 0.126 mg/I (almost double)
I hope that helps!

Subject: Timkin Company
Stan has promised that he and I will do an inspection of the Timkin company facility in Rutherford Co.
(#NCG030270). They say they are in Tier III sampling due to copper benchmark exceedances. There is literally nothing in
our g: drive on this company and no hard copy file or even a folder. I looked at BIMS and see no inspection or basically
anything.
I got the permit # from the facility and a copy of their most recent analytical data. Their copper data is consistently at
<.005, except on 9/2013 they had .01 mg/I and 5/2016 they had .009 mg/I. I wouldn't think this would require Tier III
sampling, or even Tier I.
Do you have any information you can pass on?
Can you please remind me of the new Cu and Zn benchmark limits? (My sticky note disappeared!)

Stan set up an inspection for us on I� 16 — so I'd like to get as educated as pa le on this site if you have any other
info.
Thanks!
