Dear Mr. Poupart,
I am writing to you to request a minor permit modification to permit#0000311 for
Mitchell-Bissell Inc. Under our current permit we are required to perform a composite sample for the
acute and chronic toxicity tests with our system. Our waste treatment plant only operates 4.5 to 6 hours
daily making it very dificult to meet this permit requirement. Much of our groundwater is reclaimed in
the manufacturing process through plating and eventually ends up through waste treatment. Part of the
groundwater also goes through the chillers and is used for the operation of hand-welders and other
production machinery. Only about a quarter of the groundwater actually goes out 003 pipe due to our
usage of this water. It would be more beneficial for us to go to a grab sample on these tests rather than
a composite sample and a grab sample would also be a more representative sample of our treatment
process. Mr.Jeff Menzel of the Asheville Regional Office conducted an onsite evaluation of our facility
January 10, 2013 and suggested this change to me since our irregular discharges do make it difficult for
the composite sample. I am enclosing his evaluation form along with a letter from The Acute Toxicity
Unit in Raleigh to support this request. If you need anything else from me concerning this please let
me know and I thank you for your attention to this matter.

Dear Mr.Stafford:
Mr.Jeff Menzel of our Asheville Regional Office recently conducted a site evaluation of your facility. Mr.
Menzel offered the suggestion that because your facility does not discharge waste water on a regular basis
perhaps it would be more appropriate to collect a toxicity grab sample rather than a composite sample.
Because your current discharge permit(NPDES NC0000311/001 &003),requires a composite sample for the
Whole Effluent Toxicity test it will be necessary for you to apply for a minor permit modification. The
Aquatic Toxicity Unit is in agreement with Mr. Menzel and we support a minor permit modification to
perform a grab sample instead of a composite sample. The facility is not discharging on a regular basis and
due to the irregular discharge,the permit requirements as a composite sample cannot be achieved. We would
therefore like to accommodate your request for use of a grab sample while your minor permit modification is
being processed. Please address your minor permit modification request to Mr.Jeff Poupart.

The sampling procedure should be immediately reviewed in the event that the discharge becomes more
continuous. We would be glad to entertain any questions you may have in the future.

Section D: Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
This facility's three outfalls include discharges from the following:
001 -Physical/chemical treatment
002- Non-contact cooling water
003-Groundwater remediation
001 Outfall. Within the last year the facility has had multiple toxicity failures resulting in civil penalties.
Investigation conducted by the operator in the fall of 2012 has yielded a likely culprit in the form of ammonia
based cleaners entering the system through a floor drain.This practice of disposing concentrated cleaning
product to the floor drains has since ceased and additional ammonia samples were taken of the 001 effluent
to monitor the situation. Future toxicity testing will conclude if this is cause of the previous year's failures.
The inspector believes that the facility took the appropriate actions to discover and hopefully eliminate a
cause of the toxicity failure.
All of the parameters on the permit are grabs with the exception of the toxicity tests for outfalls 001 and 003;
these tests are composites. The facility discharges in batches and does not necessarily achieve a true
24-hour flow. It is the recommendation of the inspector that the facility reviews its sampling procedure for
the two toxicity tests and makes a request to change the sample type from a composite to a grab.The
facility may find that this would be beneficial and would result in a better representative sample of the
discharge.
The clarifier is at or near the age of its life expectancy; an evaluation should be conducted to determine if
rehabilitation or replacement of the clarifier would be the better course of action.
002 outfall.This outfall contributes very little to the overall discharge from the facility.The facility also has a
very good water recirculation and reuse procedure in place for the 001 and 002 outfalls resulting in an
overall reduction of flow actually discharged to West Fork of the French Broad.
003 outfall.The groundwater remediation air stripper appears to be operating well. During the inspection it
was observed that landscaping equipment and gas cans are being stored in the air stripper building.
Precaution should be used when storing this equipment in the same building as they have the potential to
interfere with the samples taken for the groundwater monitoring.As mentioned above it is the
recommendation of the inspector that the facility review its sampling procedure for the two toxicity tests and
make a request to change the sample type from a composite to a grab for both the 001 and 003 outfalls.
This facility is well operated and no violations of permit requirements or applicable regulations were
observed during this inspection. Mr. Stafford is very knowledgeable about the system and his assistance
during the inspection is appreciated.
