All pert -nits require qualitative monitoring to be performed during a "measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DEML,R
Regional Office.

Hi Bob,
Thanks for following up. Unfortunately, I'll be out of town Wed — Mon, so it looks like we won't get to chat soon. I
propose that we skip a review meeting with you all on this one facility, but I'm open to contradiction.
I'm considering these factors forjust the specific permit application in hand now. Compost Central will discharge to
Gum Branch, a WS-IV water.
• The facility in question will be discharging a stormwater, as defined by NC General Statute, not a wastewater.
• Our General Permit for composters requires quarterly stormwater monitoring for TSS, COD, Fecal, TN, TP, Cu,
Pb, Zn, and pH with benchmark values in place to trigger the permittee's response to high values. Generally the
folks at Mecklenburg County Solid Waste have been pretty good environmental citizens as far as our program is
concerned.
• The site stormwater flow will be rainfall driven, meaning that the receiving water will also be responding to the
rainfall, and will not be at low flow (like 7Q10 for example) but something higher.

The facility is proposing a substantial detention pond (nominally 500' x 200') which presumably will provide
treatment better than that provided at the original site, which had no comparable stormwater treatment
practices.
My other consideration concerns your eventual review of the General Permit for composters when it comes up for
renewal in 3Q2016. At that time we would appreciate your review similar to the review you provided for our General
Permit for mining discharges. I had hoped to use the current application in hand to perhaps start that conversation with
you all, but I think we can postpone that until closer to the time that we are actively working on the renewal of the
General Permit.

Subject: stormwater discharge into a WS-IV
Hi Jessica,
Hi Bob,
When we coordinated on the PWS review for the Stormwater Permitting Program mining General Permit NCG02 we
mentioned that there are two other stormwater General Permits that also authorize wastewater discharges, NCG14 for
ready -mix concrete, and NCG24 for composting operations. (Both of which are up for renewal in 2016, and for which we
would like again to talk about an expedited process between our Sections.) I'd like to make you aware of a permit
application in house now from a proposed compost site, in order to see how you would like to treat it.
I'd like to meet with you face to face if it is convenient for vou, but for vour background, here are the elements of our
concern with this one:
• Mecklenburg County has applied for authorization to discharge under our General Permit NCG24 for composting
activities. Similar to the mining permit, NCG24 authorizes both wastewater and stormwater discharges. This
site will be the new Compost Central, replacing the current Compost Central located six miles south and
adjacent to the airport, and currently discharging into Coffey Creek. Old Compost Central will be shut
down. The new facility will be Charlotte/Mecklenburg's main composting facility, the largest yard waste site in
the state. Yard waste sites are classified as Type 1 facilities by our brothers and sisters in the Div. of Waste
Management.
• The discharge will be into Gum Branch, a WSAV water that goes to Long Creek and then to Lake Wylie in the
Catawba River Basin.
• Your review of our intent to issue a permit authorizing a wastewater discharge is required by rule.
• However, in this case the aspect that we want to be clear with you on is that all discharges from a DWM Type 1
composter (a yard waste composter) have been deemed to be stormwaters by SL 2012-200. So, our permit will
have to regulate these discharges in accordance with just the stormwater provisions of NCG24.
• And so, by one perspective, why am I bothering you with this? Since you are not required to review our permits
for stormwater discharges. It's more along the lines of full disclosure and effective coordination between our
programs.
• While it is generally true that discharges from a compost site are rainfall -driven, that's not the same as assuming
that the untreated runoff will be relatively innocuous, like some might assume for most stormwaters. Untreated
stormwater runoff from compost facilities varies wildly wrt pollutant concentrations. There is no reliable
generalized characterization available for compost site runoff. Under very bad circumstances untreated runoff
can be comparable to raw sewage for many pollutants.
• Our permit NCG24 requires quarterly sampling and has numerical benchmarks intended to control the pollutant
content in stormwater discharges. We have benchmark values for TSS, COD, fecal, TN, TP, Cu, Pb, Zn, and
pH. The exceedance of a benchmark kicks the permittee into a Tiered response action structure, with
increasing management attention and actions required as the Tiers escalate to Tier 1, Tier 2, Tier 3.
• The applicant has provided a partial site plan showing a rather sizable forebay and wet detention pond
(nominally 500' x 200' out to out, and 10' deep) including forebay. A pretty substantial wet pond in most
contexts. Maybe in this context, too. So, the stormwater discharge will not be untreated.
That's enough background I think. Is either one of you available to discuss this Friday or Monday or Tuesday? I'll be glad
to pop up to the 13t' floor. Again, what I'm interested in is being sure that our programs are in sync on this unusual set
of circumstances.
Thanks,
Ken

Subject: General Permit No. NCG240000
Compost Central
COC NCG240016
NCS000382 (Rescinded)
Mecklenburg County
In accordance with your application. for an NPDES stormwater discharge permit received on June
2, 2014, we are forwarding herewith the subject certificate of coverage to discharge under the
subject state — NPDES general permit. This permit is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the US Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
Based on your representation in the permit application that Compost Central is a Type 1
compost facility, the provisions of the recently enacted Session Law 2012-200 pertain to the
facility. Consistent with the provisions of SL 2012-200, DWQ will permit all the composting
discharges from your Type 1 facility under the stormwater discharge provisions of the permit, and
the General Permit requirements related to process wastewater discharges do not apply to the
composting discharges from your Type 1 facility.
During our telephone discussions, your staff indicated the facilities operation has changed to

CERTIFICATE OF COVERAGE No. NCG240016: authorizing SURFACE WATER DISCHARGES
under the National Pollutant Discharge Elimination System (NPDES) program.
In compliance with the provision of North Carolina General Statute 143-215.1 as amended by North
Carolina Session Law 2012-200, other lawful standards and regulations promulgated and adopted by
the North Carolina Environmental Management Commission, and the Federal Water Pollution Control
Act, as amended,
Mecklenburg County
is hereby authorized to discharge from a Type I composting facility (as defined in 15A NCAC 13B
.1400) located at
Compost Central
5631 West Boulevard
Charlotte
Mecklenburg County
to receiving waters designated as Coffey Creek, a class C, water in the Catawba River Basin.
Pursuant to the provisions of Session Law 2012-200, a Type 1 composting facility is not required to
have a NPDES permit for discharge of process wastewater. Notwithstanding any contrary provisions
in the General Permit, all discharges of stormwater, including stormwater which comes into direct
contact with or results from the production or use of any raw material, intermediate product, finished
product, byproduct, or waste product are authorized which comply with the-stormwater pollution
management requirements, monitoring requirements, reporting requirements, and other conditions set
forth in Part 1, Part II A - D, Part IV, Part V, Part VI, and Part VII of General Permit No. NCG240000.
In accordance with the provisions of Session Law 2012-200, the process wastewater management
requirements do not apply to the composting discharges from this Type 1 facility, and all composting
operation discharges are authorized when the facility complies only with the stormwater provisions of
the General Permit. To the extent any provisions may be read to impose the process wastewater
standards in the General Permit to discharges from the permittee's facility, the provisions are
suspended and do not apply.
This Certificate of Coverage is an enforceable part of General Permit NCG240000, and shall become
effective for the permittee on July 14, 2014,
This Certificate of Coverage shall remain in effect for the duration of the General Permit.

Mecklenburg County — Compost Central
Operations and Maintenance Manual
Revised January 31, 2011
General Information
Mecklenburg County's compost facility, Compost Central, is located on 86 acres ]eased from
the City of Charlotte, Charlotte/Douglas International Airport. The land is located within the
limits of the City of Charlotte. An additional portion of the land is used for a full service,
staffed recycling center. The land is situated across West Boulevard from the end of one of
the airport runways.
Compost Central's operating area consists of approximately 33 acres,. The facility receives
approximately t00,000 tons of yard waste and clearing debris and produces over 14,000
cubic yards of compost and an additional 200,000 cubic yards of mulch which is sold to
citizens, landscape contractors, and as boiler fuel.
There are currently two scales at Compost Central. All customers disposing of material and
customers purchasing products must cross the scale at the scalehouse.
All incoming material is weighed .with the exception of pick-up and automobile traffic.
These customers are charged by the size of vehicle and their weight is based upon historical
data. Material being sold (compost, mulch, nuggets, and etc.) are sold on a per cubic yard
basis. In addition, material sent out as boiler fuel in tractor trailers is tracked on a per load
basis (100 cubic yards per load).

Mecklenburg County —Compost Central
Operations and Maintenance Manual
Revised January 31, 2011
Quality Assurance Plan
Inspection of Incoming Material
1. The cashier initially performs visual screening of incoming material at the time it is
being weighed. The inspection is to insure that no municipal solid waste, recyclables,
household hazardous waste, treated wood, dirt or other contaminants are in the load.
2. if any of these items are detected at this time, the customer is directed to dispose of
the materials in an approved disposal facility.
3. The heavy equipment operators perform the second and primary screening on the
tipping pad. These operators inspect the material both at the time of tipping as well
as immediately before the material is placed into the tub grinders to ensure that
material type as well as size are appropriate to be processed by the grinders.
4. Should any non -conforming waste be detected by the operators during grinding
operations, the waste is loaded into a 40-yard open top container located on site,
which when full is removed from the site to be disposed properly.
Material Preparation
1. After inspection, the material is ground in the tub grinders using a 2" x5" screen for
sizing.
2. The ground material is then removed from the processing area and placed into
windrows for composting.
3. Upon placement of the material into windrows, moisture requirements are determined
by performing a squeeze test of the material:
a. A handful of material is gathered and squeezed in one hand.
b. If the material does not stay in a ball, but falls apart after squeezing it, the
moisture is probably below 50%.
c. If the material stays in a ball and little or no moisture drips from the ball, then
this is interpreted as 50%-60% moisture — the optimum moisture content.
d. If water is dripping from the ball of material, then moisture content is most
likely above 65%.
4. Natural rainfall usually provides enough water to keep the moisture content of the
material at optimum conditions. In the event of a low rainfall period, a water truck is
available to provide additional water to maintain optimal moisture content of the
windrows.
4

Mecklenburg County — Compost Central
Operations and Maintenance Manual
Revised January 31, 2011
5. In normal operations, high nitrogen yard wastes are incorporated into windrows as
soon as possible to minimize odors. All yard waste, including green waste (grass
clippings), is processed through the tub grinder within twenty-four hours of being
received. The grinding process gives the material its initial charge of oxygen for its
aerobic decomposition. The material is then incorporated into windrows within
seventy-two (72) hours if space is available or is sent out as boiler fuel.
6. During the high green waste season (spring) incoming materials have enough woody
waste content that the processed material can be sold as boiler fuel.
Composting Process
Generally, the windrowed material is turned as needed using a Backhus windrow
turner. This is necessary so that the temperature of the material remains at or above
55°C (131 °F). In addition, windrow turning keeps the process aerobic, which
minimizes odor problems.
2. Throughout the composting process the material is monitored qualitatively for
moisture content and aesthetics.
3. Temperatures of the windrows are typically measured at least once a week at three
equally spaced distances along each windrow. The temperature is measured with a
four -foot analog thermometer fully inserted toward the cross -sectional center of the
windrow. The indicator needle is allowed to stabilize (typically one minute), and the
reading is recorded.
Final Product
l . The compost material is turned regularly until the internal temperature falls below 55
°C.
2. Upon reaching the desirable temperature the material is screened at three -eighths
(3/8) inch to remove any non -conforming waste that may have been missed during
the original screening.
3. The material passing the 3/8-inch screen is placed in a curing pile separate from the
rest of the facility for approximately one month and is then ready for distribution.
4. The material not passing the 3/8-inch screen is re -screened at 1-inch.
5. The material passing the 1-inch screen is sold as mulch.
6. The material not passing the 1-inch screen is sold as boiler fuel.

In normal operations, high nitrogen yard wastes are incorporated into windrows as
soon as possible to minimize odors. All yard waste, including green waste (grass
clippings), is processed through the tub grinder within twenty-four hours of being
received. The grinding process gives the material its initial charge of oxygen for its
aerobic decomposition. The material is then incorporated into windrows within
seventy-two (72) hours if space is available or is sent out as boiler fuel.
6. During the high green waste season (spring) incoming materials have enough woody
waste content that the processed material can be sold as boiler fuel.
Composting Process
1. Generally, the windrowed material is turned as needed using a Backhus windrow
turner. This is necessary so that the temperature of the material remains at or above
55°C (131 °F). In addition, windrow turning keeps the process aerobic, which
minimizes odor problems.
2. Throughout the composting process the material is monitored qualitatively for
moisture content and aesthetics.
3. Temperatures of the windrows are typically measured at least once a week at three
equally spaced distances along each windrow. The temperature is measured with a
four -foot analog thermometer fully inserted toward the cross -sectional center of the
windrow. The indicator needle is allowed to stabilize (typically one minute), and the
reading is recorded.
Final Product
The compost material is turned regularly until the internal temperature falls below 55
°C.
2. Upon reaching the desirable temperature the material is screened at three -eighths
(3/8) inch to remove any non -conforming waste that may have been missed during
the original screening.
The material passing the 3/8-inch screen is placed in a curing pile separate from the
rest of the facility for approximately one month and is then ready for distribution.
4. The material not passing the 3/8-inch screen is re -screened at 1-inch.
5. The material passing the 1-inch screen is sold as mulch.
6. The material not passing the 1-inch screen is sold as boiler fuel.

General Information
Mecklenburg County's compost facility, Compost Central, is located on 86 acres leased from
the City of Charlotte, Charlotte/Douglas International Airport. The land is located within the
limits of the City of Charlotte. An additional portion of the land is used for a full service,
staffed recycling center. The land is situated across West Boulevard from the end of one of
the airport runways.
Compost Central's operating area consists of approximately 33 acres,. The facility receives
approximately 100,000 tons of yard waste and clearing debris and produces over 14,000
cubic yards of compost and an additional 200,000 cubic yards of mulch which is sold to
citizens, landscape contractors, and as boiler fuel.
There are currently two scales at Compost Central. All customers disposing of material and
customers purchasing products must cross the scale at the scalehouse.
All incoming material is weighed with the exception of pick-up and automobile traffic.
These customers are charged by the size of vehicle and their weight is based upon historical
data. Material being sold (compost, mulch, nuggets, and etc.) are sold on a per cubic yard
basis. In addition, material sent out as boiler fuel in tractor trailers is tracked on a per load
basis (100 cubic yards per load).

Quality Assurance Plan
Inspection of Incoming Material
1. The cashier initially performs visual screening of incoming material at the time it is
being weighed. The inspection is to insure that no municipal solid waste, recyclables,
household hazardous waste, treated wood, dirt or other contaminants are in the load.
2. If any of these items are detected at this time, the customer is directed to dispose of
the materials in an approved disposal facility.
3. The heavy equipment operators perform the second and primary screening on the
tipping pad. These operators inspect the material both at the time of tipping as well
as immediately before the material is placed into the tub grinders to ensure that
material type as well as size are appropriate to be processed by the grinders.
4. Should any non -conforming waste be detected by the operators during grinding
operations, the waste is loaded into a 40-yard open top container located on site,
which when full is removed from the site to be disposed properly.
Material Preparation
I. After inspection, the material is ground in the tub grinders using a 2" x5" screen for
sizing.
2. The ground material is then removed from the processing area and placed into
windrows for composting.
3. Upon placement of the material into windrows, moisture requirements are determined
by performing a squeeze test of the material:
a. A handful of material is gathered and squeezed in one hand.
b. If the material does not stay in a ball, but falls apart after squeezing it, the
moisture is probably below 50%.
c. If the material stays in a ball and little or no moisture drips from the ball, then
this is interpreted as 50%-60% moisture — the optimum moisture content.
d. If water is dripping from the ball of material, then moisture content is most
likely above 65%.
4. Natural rainfall usually provides enough water to keep the moisture content of the
material at optimum conditions. In the event of a low rainfall period, a water truck is
available to provide additional water to maintain optimal moisture content of the
windrows.
