2 quantities listed in units of lb/day.      

3 NODI=B is an EPA indicator code that means “below detect level/no detect.”  

*These load values were calculated by converting the largest concentration values via the corresponding flowrate values listed on the DMRs.    

IV.	BACKGROUND/DOMESTIC LOADING CALCULATIONS

Background Loading (BGL), lb/day = 8.34 x BGC (mg/L) x (QPOTW - QINDUSTRIAL) (MGD)

BGC = Background concentration of domestic sewage.  Calculated from actual POTW data as shown in Appendix A.  

QINDUSTRIAL = QW1 + QW2 + …
where QW is the largest average flowrate from the DMRs over a recent twelve month period.  (Maximum flowrate data may be used when monthly average data is not available.)

BGL (Cd) = 8.34*0.00097*(39 – 0.111711) = 		0.315 lb/day
BGL (Cr) = 8.34*0.0044*(39 – 0.307711) = 			1.42 lb/day
BGL (Cu) = 8.34*0.069*(39 – 0.133311) = 			22.4 lb/day
BGL (Pb) = 8.34*0.0048*(39 – 0.171811) = 			1.55 lb/day
BGL (Ni) = 8.34*0.0054*(39 – 0.111711) = 			1.75 lb/day
BGL (Ag) = 8.34*0.00036*(39 – 0.048111) = 		0.117 lb/day
BGL (Zn) = 8.34*0.12*(39 – 0.389411) = 			38.6 lb/day
BGL (CN) = 8.34*0.0025*(39 – 0.053111) = 		0.812 lb/day

V.	WATER QUALITY ANALYSIS

A.	Instream Wastewater Concentration

IWC, % = [QPOTW / (QPOTW + Q7/10)] x 100 = [39/(39 + 147)]*100 = 21 %

Since IWC > 1%, both acute and chronic screening are developed.  

B.	Allowable Water Quality Criteria (AWQC) Headworks Loading Calculations

AWQC, lb/day = 8.34 x CCRITICAL (mg/L) x (Q7/10 + QPOTW, MGD) / (1 – RPOTW)

CCRITICAL = Critical Concentration; obtained from State of Mississippi Water Quality Criteria for Intrastate, Interstate, and Coastal Waters: Freshwater Acute and Chronic Values.  Adopted June 28, 2012.  

RPOTW = Removal efficiency, in decimal form, from actual POTW data (Appendix B) or from MDEQ-observed study data for those pollutants with insufficient data.  

ACUTE SCREENING:  

AWQC (Cd) = 8.34*0.00103*(147 + 39)/(1 – 0.891) = 	14.7 lb/day
AWQC (Cr) = 8.34*0.323*(147 + 39)/(1 – 0.896) = 	4818 lb/day
AWQC (Cu) = 8.34*0.0070*(147 + 39)/(1 – 0.909) = 	119 lb/day
AWQC (Pb) = 8.34*0.030*(147 + 39)/(1 – 0.948) = 	895 lb/day
AWQC (Ni) = 8.34*0.260*(147 + 39)/(1 – 0.596) = 	998 lb/day
AWQC (Ag) = 8.34*0.00098*(147 + 39)/(1 – 0.900) = 	15.2 lb/day
AWQC (Zn) = 8.34*0.065*(147 + 39)/(1 – 0.838) = 	622 lb/day
AWQC (CN) = 8.34*0.0220*(147 + 39)/(1 – 0.62) = 	89.8 lb/day

CHRONIC SCREENING:  

AWQC (Cd) = 8.34*0.00015*(147 + 39)/(1 – 0.891) = 	2.13 lb/day
AWQC (Cr) = 8.34*0.042*(147 + 39)/(1 – 0.896) = 	626 lb/day
AWQC (Cu) = 8.34*0.0050*(147 + 39)/(1 – 0.909) = 	85.2 lb/day
AWQC (Pb) = 8.34*0.00118*(147 + 39)/(1 – 0.948) = 	35.2 lb/day
AWQC (Ni) = 8.34*0.029*(147 + 39)/(1 – 0.596) = 	111 lb/day
AWQC (Ag) = 8.34*NA*(147 + 39)/(1 – 0.900) = 		NA
AWQC (Zn) = 8.34*0.065*(147 + 39)/(1 – 0.838) = 	622 lb/day
AWQC (CN) = 8.34*0.0052*(147 + 39)/(1 – 0.62) = 	21.2 lb/day

NA = no critical concentration for chronic silver screening is available from either Mississippi or EPA guidelines.  

VI.	POTW INHIBITION ANALYSIS (HEADWORKS INHIBITION, HWI)

HWI, lb/day = 8.34 x QPOTW (MGD) x CINH (mg/L)

CINH = Activated Sludge Inhibition Levels, from EPA Guidance Manual on the Development and Implementation of Local Discharge Limitations Under the Pretreatment Program: Table 3-2 Activated Sludge Inhibition Threshold Levels.  For the silver parameter, the minimum reported inhibition threshold is utilized.  For all other parameters, 1.0 mg/L is used since this value is near the minimum side of the minimum reported range of inhibition threshold levels.  

HWI (Cd) = 8.34*39*1.0 = 		325 lb/day
	HWI (Cr) = 8.34*39*1.0 = 		325 lb/day
	HWI (Cu) = 8.34*39*1.0 = 		325 lb/day
	HWI (Pb) = 8.34*39*1.0 = 		325 lb/day
	HWI (Ni) = 8.34*39*1.0 = 		325 lb/day
	HWI (Ag) = 8.34*39*0.25 = 		81.3 lb/day
	HWI (Zn) = 8.34*39*1.0 = 		325 lb/day
	HWI (CN) = 8.34*39*1.0 = 		325 lb/day

*If AWQC < HWI, then LC = AWQC; if AWQC > HWI, then LC = HWI.  

NA = no critical concentration for chronic silver screening is available from either Mississippi or EPA guidelines.

VIII.	   DEVELOPMENT OF ALLOWABLE CONCENTRATIONS

The remaining industrial wasteload allocation will be used in calculating allowable acute and chronic concentrations using the “Industrial User (IU) Contributory Flow” method as described in EPA’s Local Limits Development Guidance (EPA 833-R-04-002A, July 2004).  

PAI, lb/day = (LC, lb/day – BGL, lb/day) x (QI, MGD / QT, MGD)

CALLOW, mg/L = (PAI, lb/day) / (8.34 x QI, MGD)

PAI 	=	Permit allocation for indirect discharger
CALLOW=	Allowable concentration for indirect discharger
QI	=	Applicant’s permitted process discharge 
QT	=	Total industrial contributory flow for pertinent pollutants
LC	=	Limiting case loading
BGL	=	Background/domestic loading

IX.	NOTABLE SAMPLING DATA FROM PERMIT APPLICATION  

Please note: Since this facility is a proposed landfill and is not yet in operation, there is no leachate generated to sample and perform analytical testing.  Therefore, the sampling data contained in the permit application was calculated based on leachate analytical data from two (2) other landfills in Mississippi: Three Rivers Regional Landfill (pretreatment permit No. MSP090943) and Prairie Bluff Landfill and Recycling Center (pretreatment permit No. MSP090940).

XII.	STATEMENT OF BASIS (narrative)

This facility is a proposed Municipal Solid Waste (MSW) landfill that will be located in Ridgeland, Mississippi.  The facility will transport process wastewater consisting of landfill leachate to the Jackson POTW located on Savanna Street in batches via truck hauling.  The facility will be permitted a daily maximum flowrate of 55,000 gallons per day (0.055 MGD).  

The following custom requirements have been added to the proposed permit:

“Within one (1) year after the commencement of discharge, the permittee shall submit a completed Pretreatment Form 2P application to MDEQ.  Based upon the results of the analyses, the permit may be reopened and reissued to reflect this data.”  [11 Miss. Admin. Code Pt. 6, R. 1.1.1.B(1).]    

“A copy of each Discharge Monitoring Report (DMR) form shall also be submitted to the City of Jackson at the following address:

Attention: Public Works Director
City of Jackson
PO Box 17
Jackson, MS  39205-0017”  [11 Miss. Admin. Code Pt. 6, Ch. 1, Subch. 1.]

DATA FOR CYANIDE (CN) BACKGROUND/DOMESTIC CONCENTRATION

Average Domestic Concentration for Cyanide (CN) = BGC = 0.0025 mg/L 

*These values are the Averages listed on the DMRs.  Average values are preferred over Maximum values because they present a more representative model of the facility’s typical effluent.  

APPENDIX B

REMOVAL EFFICIENCIES – Jackson POTW, Savanna Street       

(Calculated and displayed in table on the next page)

1 Removal Efficiency = [(<inf.> - <eff.>)/<inf.>]*100, where <inf.> is the average influent value and <eff.> is the average effluent value.

Yellow Shaded Values were excluded because either the inf. > eff. or inf. = eff. for the same sample date.  

Blue Values were used in “non-detect” results in which the Method Quantitation Limit (MQL) was then divided by 2 to obtain the blue value.  

*Due to indeterminate data from the actual POTW, MDEQ-observed study data for activated sludge systems was used.

ADEQUACY OF TREATMENT 

Date:					April 2, 2018        
Project Manager:			Carter Cress
Proposed Site:			NCL Waste LLC, 
					North County Line Landfill    
					Pretreatment Permit No. MSP092399   
					Madison County  
Address:				2858 North County Line Road
					Ridgeland, MS  39157    

Proposed Hydraulic Loading:	0.055 MGD (maximum daily value; from permit application)
Proposed Organic Loading:	329 mg/L (maximum daily value; from permit application); 
329 mg/L *8.34*0.055 MGD = 151 lb/day (max.) 

Jackson POTW, Savanna Street, NPDES Permit No. MS0024295, AI No. 13201
Permitted Flow (lowest value; months May – October):		46 MGD avg.
12 Months Flow:	39 MGD avg. value (DMR data from January 2017 through December 2017)
12 Months BOD5: 	31,327 lb/day avg. influent (DMR data from January 2017 through December 2017)  

Evaluation of Flow
46 MGD permitted – 39 MGD actual = 7 MGD available vs. 0.055 MGD proposed

Evaluation of BOD5
Permitted flow 46,000,000 gpd/(100 gallons/person/day) = 460,000 population equivalency
460,000*0.17 lb BOD/person/day = 78,200 lb/day BOD capacity
78,200 lb/day available – 31.327 lb/day (avg. POTW influent) = 46,873 lb/day
46,873 lb/day available vs. 151 lb/day proposed
