All permits 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 DEMLR
Regional Office,

Ail permits 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 DEMLR
Regional Office.

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 backeround, 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 WS-IV 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 um 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 13th floor. Again, what I'm interested in is being sure that our programs are in sync on this unusual set
of circumstances.
Thanks,
Ken

Mr. Coker,
In response to your request (via email dated January 06, 2015) for a formal determination of the low -flow characteristics on Gurri
Branch below Caldwell Williams Road at Homestead in Mecklenburg County, the following information is provided:
A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not indicate a
previous low -flow determination for your specific point of interest on Gum Branch as identified by the map image attached
to your email dated January 7, 2015. No USGS discharge records are likewise known to exist for your point of interest.
In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -flow characteristics at
ungaged locations are determined by assessing a range in the low -flow yields (expressed as flow per square mile
drainage area, of cfsm) at nearby sites where such estimates have previously been determined.
A drainage -area delineation completed using the online NC StreamStats application
(httpJ%water.usgs.gov/osw/streamstats/north carolina.html) indicates the drainage area for your point of interest on Gum
Branch is 1.94 sgmi!

Previously published low -flow information for streams in your area of interest
For streams in western Mecklenburg County, the most recently published low -flow information is a
statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, 'Low -
flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the
report is available at http://pubs.usgs.gov/wsp/2403/rei)ort.pdf. Ti he report provides the lows
flow characteristics (based on data through 1988) via regional relations and at -site values for sites
with drainage basins between 1 and 400 sgmi and not co
regulation and/or diversions.
Please note the low -flow characteristics in the statewide re

(1) As noted above, please be aware the low -flow characteristics in the above -referenced report are based on data ending
during the late 1980's that do not reflect the occurrence of recent droughts, which have resulted in decreased low -flow
statistics at some USGS streamgaging stations. The USGS South Atlantic Water Science Center (Raleigh office) has
recently completed an update of low -flow characteristics and flow -duration statistics for selected continuous -record
streamgages_across North Carolina. At a nearby USGS continuous -record streamgage on Long Creek near paw Creek it
Mecklenburg County (station id 02142900, drainage area 16.4 sgmi, period of record since June 1965),
the 7Q10 discharge decreased about 43 percent between the 1998 and 2011 climatic yearJ_
(2) The climatic year is the standard annual period used for low -flow analyses at continuous -record streamgages and runs
from April 1 through March 31, designated by the year in which the period begins. For example, the 2011 climatic year is

For the design of the County's yard waste composting facility, I need to prepare an Engineering Alternatives
Analysis (EAA) for NCDENR to review prior to storm water discharge permit issuance. The EAA Guidance
calls for estimates of both the Summer and Winter 7Ql 0, the 30Q2 and average flow. Do you have those
estimates for Gum Branch (a tributary to Long Creek which flows into Lake Wylie on the Catawba River)? 1
can email you a map showing where the discharge enters Guar Branch (about 0.25 miles upstream of the NC-16
crossing over Gum Branch).

• ':.. wet detention pond...sized for the 24-hr 25- r storm" Please note that as port of the application review we
will not review the selection, sizing, or design sufficiency of the intended treatment and „control measures. i
mean, our regulatory model in this case is to simply require the permittee to meet the numerical wastewater
limits. We will not tell him how to do that in the opplication review and permit coverage issuance
process. Further, we are specificallyprohibited from reviewing the design of industrial wastewater treatment
facilities per specific North Carolina law provisions in SL 2011-394, cited on the additional NCG24 General Permit
cover page issued December 8 2011.
• "...commingled stormwater runoff and process wastewaters" As you already understand, 1 know, the
commingling of any other Llow with a wastewater flow subjects the combined flow to the wastewater provisions
of the permit, not the stormwater provisions. Unlike the other issues in your uestion this is well established in
the Stormwater Permitting Program's past practice, and we don't have any uncertainty on this point.
• `:..have TMDLs (nutrients and turbidity ...)... a letter request for Speculative Effluent Limits" OK, this is o more
detailed issue, and Mike Templeton will have to help us when the ooplication is received, or before: Some of the
elements that might be involved could be as follows. -
o Mike reports that the TMDL applicable in that location is an older one (-1995), and the methodology
applied at that time has since evolved in other TMDLs. So, this could be a special case when we get to
evaluating this new site.
o There are several uncertainties involved at this point in time. _Consider that the TMDL for that watershed
includes nutrient allocations for wastewater treatment facilities discharging lows measured in MGD
2417. Incorporating a sporadic roinfoll-driven flow into the overall nutrient allocation calculation
presents some uncertainties, although I think that similar considerations hove been incorporated before.
o A corollary to the presence of WWTP discharging in MGDs is that the nutrient contribution from the new
site may fall below the significant mass: 1 mean, consider that the nutrient allocation for a WWTP
discharging several MGD will probably (?) dwarf the nutrient mass from the new site, and the new
nutrient load rnoyf2fl out of_the _ allocation calculation base on it being orders of magnitude smaller than
the other allocations.
o If the old Compost Central also discharged into the some watershed, subiect to the some TMDL, there
may a regulatory_path through the observation that the new nutrient contribution is equal to or less
than the contribution from the old site. i note that the airport is on the west side o f Charlotte, but I'm
not certain if the two sites (old and new) actually contribute to the same TMDL area.
o A beginning point might be to assemble the data available from old Compost Central and tabulate the
nutrient analytical results and flows (if we have flow measurements or estimates.) I know they have
some historical nutrient analyses.
o As 1 understand it Lrom Mike,_ speculative effluent limits are water quality based limits. They are always
more stringent than technology based limits. The four parameters contained in NCG24 are technology
based limits.
o If it turns out that the nutrient moss contribution from this site is significant then Mike reports that
other WWTP in other TMDLs are seeing single digit concentrations (back -calculated from the mass
allocation.) The phosphorus limit is more or less around 1 mq1L. The nitrogen limit is more or less
around 6mg/L, all varying with the particular receiving water and other allocations.
o Further, if a TMDL allocation calculation determines that this site would have a significant nutrient
contribution, then we would incorporate the additional nutrient concentration permit limits in an

amended Certificate of Coverage. The amended COC would essentially add nitrogen and/or phosphorus
to the monitoring suite, in addition to the parameters already in place in NCG24: TSS, BOD, fecal, and pH.
• It might be good to check on what if any, local restrictions would ooply based on the presence of a water supply
watershed. Is this location in a WSWS? There are some constraints on new wastewater discharges into some
WSWS.
So, potential action items are:
o I'd suggest that you tabulate the historical nutrient measurements from old Compost Central as on
indicator of what could be expected from new Compost Central. Some crude flow_ measurement
estimation from the new site would also be helpful in the mass calculation, I think. (Mike will hove to
help us more when you're ready for that help.)
o Resolve whether or not the old and new site discharge to the some TMDL area.
o Let us know if the site is in a WSWS. ^
o It may be that we can reach a conclusion that the nutrient mass contribution is insignificant. But, we
don't want to do that 'by observation' or by 'best Professional1udgment'. We want to do that
numerically to the level of rigor that Mike helps us determine as appropriate. This protects both us
and Mecklenburg County.
Thanks, and if you have any questions, please call.

Mike,
As a part of the development of our regulatory program regulating surface water discharges (both ww and sw) from
composting facilities, a couple of Session Laws specifically favoring Type 1 facilities (yard waste) were passed in 2011
and 2012.
One says, "The Division of Water Quality shall not require water quality permitting for any Type 1 solid waste compost
facility, unless required to do so by federal law." SL 2011-394
The other says, "A Type 1 solid waste compost facility shall be subject only to applicable State stormwater
requirements and federal stormwater requirements established pursuant to 33 USC 1342(p)(3)(B). A Type 1 solid
waste compost facility shall not be required to obtain a national Pollutant Discharge Elimination System (NPDES)
permit for discharge of process wastewater based solely on the discharge of stormwater that has come into contact
with feedstock, intermediate product, or final product at the facility. " SL 2012-200. (See federal definition of process
wastewater at 40CFR122.2 for an interesting comparison.)
We have only applied this 2012 law a few times, but exclusively for the municipal Type 1 yard waste composters. We
have told them that according to Session Law they are governed only by the stormwater provisions of our General
Permit, NCG24, not the wastewater provisions (NCG24 is one of our combo ww + sw General Permits that we
administer.)
So,,,,,,,,,,,,,,,,,,,,,,,,,,,,I think we may be moving toward avoiding any consideration of revised BOD limits in our permit for
the new Compost Central facility. I mean, according to state law they are not subject to the wastewater requirements of
our permit (BOD limits of 30/4S mg/L.) It only makes sense that if they're not subject to BOD limits in the General
Permit, they wouldn't be subject to any revised WQBEL BOD limits in the permit, either.
But, I think we need to meet with you and/or Tom to see how the NPDES wastewater programs would consider
whether a WQBEL would be relevant in these circumstances. We'd like to double check our understanding and your
past history (if any) on related interpretations or implementations of law, rule, and NPDES permit conditions.
Can you be available to chat with us about this?

Hi Craig,
Oops: Although my first citation to SL 2011-394 (Section 7) does make special provisions for Type 1 facilities, the more
specific Type 1 facility citation for our purposes here is SL 2012-200 Section 5. We will look at these two laws closely wrt
the issue of wastewater/BOD limits/low flow (but not zero flow) streams.

Hi Craig,
We're still chugging on this question about BOD.
Another aspect to consider is Session Law 2011-394 that we have heretofore interpreted (City of Raleigh Yardwaste
facility) as directing that discharges from a Type 1 facility should be regulated as stormwaters, not wastewaters. So, we
need to go back to that statute, parse the words to be sure of our interpretation in these circumstances, compare them
to the zero -flow stream rule, compare that to the permit text, and be sure that we've got an approach consistent with
law, rule, and permit text. Oh, and by the way lest we overlook it, also protective of the receiving water.
I'm assuming that new Compost Central will be a Type 1 facility, right?

Thanks, Craig,
Bethany reminds me that there is also a provision in North Carolina rules prohibiting the discharge of oxygen consuming
wastes into 'zero -flow streams'. I think we need to know that Gum Branch is not a zero -flow stream. The rule citation
is: 15A NCAC 02B .0206, and the most restrictive part of that rule is .0206(d)(2),
"If the 30Q2 and 7Q10 flows are both estimated to be zero, no new or expanded (additional) discharge of oxygen consuming
waste will be allowed."

Note that this part of the rule applies only to new discharges —which the new Compost Central would be. And that the
restriction is limited to streams where both flow statistics are zero (30Q2 and 7Q10). Other parts of the rule are less
restrictive. As I understand the application of this rule, even treated wastewater is considered to be a discharge of
oxygen consuming wastes, and so the rule effectively prohibits treated wastewater discharges into zero -flow streams.
I mention this because while it appears that the site is not exactly on the headwaters of Gum Branch, it's not too far
downstream either, according to the map I'm looking at. If this is an issue, let's face it early.

Hi Craig,
I've looked at the Google Map aerial photos, and I see a likely farm tract off Pleasant Grove Road, which would drain
exclusively to Gum Branch. Julie Ventaloro, our water supply watershed program coordinator, confirms that Gum
Branch is WS-IV. The whole run of Gum Branch is sufficiently removed (several miles) from Lake Wylie to be outside of
the WS-IV Critical Area, and so the treated.site wastewater discharges would be allowed, and would not be subject to
the Critical Area special restrictions.
Mike Templeton corrected my generalization on speculative effluent limits in my previous email below: "They are
almost always more stringent than technology based limits." In this case the difference may not be significant since the
wastewater limits entered into the permit are always the more stringent of technology or water quality (speculative)
based limits.
Further, I note that old Compost Central at the airport drains to Coffey Creek, which enters the Catawba River in South
Carolina. So, I'm not sure if we can claim that the new and old nutrient loads into the basin just cancel out for no net
increase. We will have to get Mike to help us with that question, if it becomes important.

Good morning, Ken and Happy New Year! I hope you've been well.
I'm working on the NGC240000 application for the relocation of Mecklenburg's Compost Central to a site in
the Lake Wylie/Long Creek/Gum Branch watershed, and am preparing an Engineering Alternatives Analysis to
address the non -discharge questions in the application form, using the April 2014 Division of Water Resources
guidance document.
Craig, strict adherence to lust the application requirements in the NCG24 NOl will suffice for permit issuance. Questions
13 a), b), c), and d) are the full extent of the Engineering Alternatives Analysis required in the application for NCG24
coverage. We deliberately abbreviated the procedure (compared to the DWR procedure) so as to make it less
burdensome on the applicant (and us, too.) You can follow the DWR guidance document if you wish, but we don't
require that full level of effort in order to consider the opplication complete. Actually_it's good that you have reviewed
that document, as it is a fuller illustration of the conceptual intent of our EAA applicable to General Permit NCG24.
As Lake Wylie and Long Creek have TMDLs (nutrients and turbidity, respectively) and as we're planning aw wet
Beten i onond as a BMP for ommingled storm water runoff and process wastewaters (sized for the 24-hr/25-yr,
storm}, would you suggest the County file a letter request for Speculative Effluent Limits, and if so, to whom
should that request be sent?
Crarq, on these questions we have hod limited experience implementing the TMDL lonquoge that has been in our permits
for years of the direction of EPA Region IV. 1 think we know how to move forward,_ nonetheless. I have spoken with Mike
Templeton in DWR's NPDES wastewater group who is our lead resource on wastewater and TMDL's. Let me list a fe
comments on -several parts of your question above, addressing the simpler issues first and addressing TMDLs lost.
