Subject: New Industrial User at Valdese WWTP
Chris,
NPDES reviewed your notification letter concerning the Town's plans to issue an Industrial User Permit (IUP) and accept
wastewater from Valdese Water Recycling, LLC.
This facility will operate as a Centralized Waste Treatment facility and its 0.200 MGD discharge will constitute approximately
10% of the daily flow; based upon 2018 average daily influent flow at the WWTP of 2.12 MGD (Jan. - Sept.). As identified, the
pollutants of concern are those designated within section 437.47 (PSNS) and have been entered into the most recent
Pretreatment AT/HWA for Valdese; with the designation of 7.5 MGD. NPDES reviewed the calculations performed as part of
this analysis and determined Water Quality Standards will be protected with the issuance of the IUP and a NPDES permit
modification is not necessary at this time. This information will be included in the Town's NPDES file and will be carefully re-
evaluated during the next permit renewal.
NPDES requests that once this Industrial User is operating the Town of Valdese perform an Effluent Pollutant Scan which
includes wastewater from the Valdese Water Recycling facility. This analysis shall be included with the next permit renewal
application for evaluation.
Thanks for informing the Division of potential changes in the wastewater being received at the WWTP.

Good Afternoon Julie,
Please find the attached letter and information regarding our conversation about the CWT coming to Valdese. Any
recommendations, statements or updates that can be provided, in a timely manner, would be appreciated. As we both
indicated, entities believe the pace of permitting should be done at their leisure, but realistically can only move so fast.
If I can be of further assistance, simply let me know. I've forwarded a bit of information to Vivien over the past month, prior to
your inclusion, so she may already have items not included in this email.
Hope you have an enjoyable weekend,

TO: Julie Grzyb
NCDEQ
Supervisor: NPDES Complex Permitting Staff
FROM: Chris Bortnick
Town of Valdese
Pretreatment Coordinator
Dear Julie,
This letter serves as notification that the Town of Valdese Pretreatment Program plans to issue
an Industrial User Permit to Valdese Water Recycling, LLC. This company will be a Centralized
Waste Treatment Facility (CWT), with plans to operate under Subcategory D
(metals/oils/organics) and applicable pretreatment standards (437.47 — PSNS). There will be
one sampling point. Based upon their submitted documentation of flow and treatment
processes, technology and modeling after similar CWT facilities, the ability to treat waste at this
facility can be achieved.
The Lake Rhodhiss WWTP (NC0041696) currently has an approved tiered permit (3.5, 7.5 and
10.5 MGD), with 3.5 MGD being the operating point at this time. Through the anticipated
addition of the CWT, loadings would indicate a move to the 7.5 MGD status.
A request by the CWT for 0.200 MGD would constitute approximately 10% of the daily flow;
based upon 2018 average daily influent flow at the WWTP of 2.12 MGD (Jan. - Sept.).
Pollutants of concern would be those designated within section 437.47 (PSNS) and have been
entered into the most recent AT/HWA for Valdese; with the designation of 7.5 MGD. The only
over -allocation noted in the AT is for Silver(Ag), due to (Ag) being the Stream Standard and the
minimum pass through basis. Furthermore, I'm not so sure that is a concern because the Ag
value should only be utilized in the HWA as an action level POC if the WWTP is failing Whole
Effluent Toxicity testing for Ag... The Valdese WWTP has not failed WET testing in many years
and definitely not for Ag, whenever it did fail. Quarterly effluent metals testing over the years
shows a dominance of "non -detect" for Silver as well.

At this time, monitored organic constituents listed within section 437.47, and others, would be
hard to determine what effects they would have on the WWTP effluent. For the last 4-5 years,
annual Priority Pollutant Analyses conducted on the WWTP effluent indicated no or minimal
detection of any stipulated volatile/semi-volatile organics required to be tested within our
NPDES permit. This includes having an industrial laundry since 2012 and a small metal -finisher
since 2016 in the Valdese pretreatment program.
Overall, understanding that CWT's can be difficult and problematic at times, the Town believes
in allowing this entity to operate and discharge to the Lake Rhodhiss WWTP, based upon
indications within the AT/HWA.
Lastly, is an NPDES permit modification necessary for the Lake Rhodhiss WWTP?
Thank you for your time and attention in this matter and look forward to your response.
Regards,
Chris Bortnick

Julie, attached is the information from Derr Leonhardt, President of Valdese Recycling. As a note, the company
went through extensive analysis with the town of Valdese Wastewater Treatment director and their pre -
treatment director as well as the Town of Valdese's Fire Marshal and the Burke County Building Inspectors' office.
Mr. Leonhardt is available 24/7 to respond to any questions or clarifications you might need for your review
process.
Again, thank you for your earlier quick response to my call. jeff

Jeff,
Attached are two laboratory reports, one analysis of proposed leachate collection wastewater, and a copy of the
Centralized Pretreatment regulations.
Here are the facts:
1. Our facility will require a complete profile analysis for each waste stream from our customer prior to
acceptance of the wastewater. We will only accept wastes which are compatible with our capabilities and
for which we can discharge within the parameters of our permit.
2. Because we are a centralized pretreatment facility, we will be dealing with a wide variety of wastewater. It is
not possible to anticipate exactly what will be offered to us for treatment. However, we will rigorously
screen all waste to ensure that nothing is accepted which would have a detrimental impact onto the Town of
Valdese system. Then we will treat the wastewater to levels well below those specified in the standard.

3. We have contracted for the acceptance and treatment of about one million gallons of wastewater for which
laboratory analyses are attached. The laboratory reports are labeled VWR STAT1 and VWR STAT#2. You will
see from the laboratory reports that nothing in the waste is inconsistent with our draft permit. These two
waste streams will be typical. For the start-up of the facility, these two waste streams will form the majority
of our incoming wastewater.
4. We are currently reviewing the acceptance of landfill leachate for which recent and historical laboratory
results are attached. If accepted, this waste stream would include about one million gallons per year. The
laboratory results attached are before -treatment values. Our discharge would obviously include lower
concentrations of all contaminants.
5. I am attaching a copy of the regulation to demonstrate that we are fully committed to full and continuous
compliance with all terms of the standard. Should the town have additional needs and requirements, we are
equally committed to meeting those.
6. We are working with a series of sister facilities (twelve facilities in both North Carolina and other states) to
which we can divert any wastewater for treatment if the wastewater is not fully compatible with our system
or the Town of Valdese system. The other facilities have advanced capabilities such as solidification and
evaporation for hard to treat wastes.
I trust that this information is sufficient to allow for the completion of the review and acceptance of our facility.

Final Compliance Date: December 22, 2003
New Source Date: August 28, 2000
Subcategories
A. Metals Treatment and Recovery Subcategory
B. Oils Treatment and Recovery Subcategory
C. Organics Treatment and Recovery Subcategory
D. Multiple Wastestreams Subcategory
Types of Technology on Which Pretreatment Standards are Based:
Metals Treatment and Recovery Subcategory:
Primary precipitation, liquid -solid separation, secondary precipitation, clarification, and sand filtration
Cyanide treatment: Alkaline chlorination in a two-step process prior to metals treatment
Oils Treatment and Recovery Subcategory:
Emulsion breaking/gravity separation and dissolved air flotation
Organics Treatment or Recovery Subcategory:
Equalization and biological treatment
Applicability:
Generally applies to wastewater generated from the treatment and recovery of hazardous and non -hazardous
industrial wastes received from off -site.
Exemptions:
Facilities that receive that receive off -site waste from the same industry or of the same nature as wastes
generated on -site.
! Treatment of waste received from off -site via pipeline.
Treatment of wastewater from product stewardship activities, limited to acceptance of unused products,
shipping and storage containers with product residues, and off -spec products.
Treatment of off -site sanitary wastes and wastes of domestic origin, such as septage, chemical toilet waste, and
restaurant waste.
Treatment of grease trap wastes and wastes from food processing and food service activities.
Treatment or recovery of solids that remain in solid fonn when contacted with water and which do not leach
any chemicals into the water, such as recycling of aluminum cans, glass, and plastic bottles.
Wastewater from scrap metal processing and auto salvage operations.
POTWs, transfer stations, and municipal recycling centers.
Truck washes that do not receive off -site waste other than "heels" of empty trucks.
Wastewater from solvent recovery if distillation is used.
Wastewater from silver recovery operations of used photographic and x-ray materials if it is not mixed with
other types of wastes.
Treatment of marine generated waste (ballast water, bilge water, etc.) as long as the waste is treated at the
servicing facility where it is off-loaded.
Metals recovery operations regulated under other federal pretreatment categories.

Subcategory Determination
To determine the appropriate subcategory or subcategories, the regulated facility should review one year's data on its
incoming wastes. Each waste receipt should be classified into the metals subcategory, the oils subcategory, or the
organics subcategory by using the list of waste streams below. To determine the appropriate category:
1. See if the waste receipt is of a type listed below. If so, the subcategory for the waste should be taken from
this list.
Metals Subcategory: spent electroplating baths and/or sludges, metal finishing rinse water and sludges,
chromate wastes, air pollution control blow down water and sludges, spent anodizing solutions, incineration
wastewaters, waste liquid mercury, cyanide -containing wastes, waste acids and bases with or without metals,
cleaning and rinsing and surface preparation solutions from electroplating or phosphating operations, vibratory
deburring wastewater, and alkaline and acid solutions used to clean metal parts or equipment.
Oils Subcategory: used oils, oil -water emulsions or mixtures, lubricants, coolants, contaminated groundwater
clean-up from petroleum sources, used petroleum products, oil spill clean-up, bilge water, ►inse/wash water
from petroleum sources, interceptor wastes, off -specification fuels, underground storage remediation waste,
tank clean -out from petroleum or oily sources, non -contact used glycols, aqueous and oil mixtures from parts
cleaning operations, and wastewater frorn oil bearing pain washes.
Organics Subcategory: landfill leachate, contaminated groundwater clean-up from non -petroleum sources,
solvent -bearing wastes, off -specification organic product, still bottoms, byproduct waste glycol, wastewater
from paint washes, wastewater from adhesives and/or epoxies formulation, wastewater from chemical product
operations, tank clean -out from organic non -petroleum sources.
2. If the waste receipt is not listed above, the following hierarchy should be followed to determine its classification;
a. If the waste receipt contains oil and grease at 100 mg/1 or above, the waste should be classified in the oils
subcategory.
b. If the waste receipt contains less < 100 mg/I oil and grease and has any of the pollutants listed below in
excess of the values listed below, the waste should be classified in the metals subcategory.
Cadmium: 0.2 mg/l
Chromium: 8.9 rng/I
Copper: 4.9 ing/1
Nickel: 37.5 mg/l
c. If the waste receipt contain < 100 mg/1 oil and grease and does not have concentrations of cadmium,
chromium, copper, or nickel above any of the values listed above, the waste should be classified in the
organics subcategory.
3. If a facility only receives wastes in one subcategory, the facility is regulated under the appropriate subcategory.
If a facility receives wastes in more than one subcategory, the facility is regulated under Subcategory D,
Multiple Wastestreams.
