AgendaThe Marquette Area Wastewater Treatment Facility (MAWTF)
Our ChallengeIndustrial Waste Control (IWC) ProgramProgram ImplementationProgram ProceduresPerspectiveSlide3
The MAWTF
Owned by City of Marquette, Marquette Township, and Chocolay TownshipOperated by City of Marquette3.85 MGD design; 2.7 MGD current88 miles of separated sanitary sewer, with 11 lift stationsHistory:1869 Initial Collection System
1953 Primary Plant1978 Secondary Upgrade #1 (RBC)
2008 Secondary Upgrade #2 (AS with nitrification and Bio-P)Slide4
The MAWTFSlide5
Our ChallengeReceived request
to accept nondomestic waste Power plant ash pond leachateGroundwater remediation projectAvailable capacity; desire to help local economyIPP not currently required by NPDES permit“It is understood that the permittee does not receive the discharge of any type or quantity of substance which may cause interference with the operation of the treatment works; and, therefore, the permittee is not required to immediately develop an industrial pretreatment program in accordance with Section 307 of the Federal Act.“Slide6
Our ChallengeResponsible for protecting collection system, treatment plant, and worker health/safety
Develop IPP?More regulationsMore manpower and costs Desired alternativeInformal IPP, but similar technical basisStreamlined procedures
No major changes to Sewer Use OrdinanceSlide7
ObjectiveProtect MAWTF from effects of nondomestic pollutants without formal IPPApply basis for
local limitsPollutants of ConcernMaximum Allowable Headworks LoadingsMaximum Allowable Industrial LoadingsCollection System Limitations
Marquette IWC ProgramSlide8
Potential Effects of Nondomestic Pollutants
Michigan Department of Environmental QualitySlide9
Pollutants of Concern (POCs)
MDEQ-recommended for IPPTypical compatibles: BOD, TSS. Total-P, Ammonia, FOGTypical toxics: As, Cd, Cr, Cu, CN, Pb, Hg, Mo, Ni, Se, Ag, ZnSite-Specific
Metals from power plant ash pond leachateOrganics from groundwater remediation projectSlide10
Maximum Allowable Headworks Loadings (MAHLs)
Not-to-exceed total pollutant mass to plantCalculated via headworks loading evaluationBasis of DesignNPDES/Rule 57 pass-throughSludge qualityBiological inhibitionHighly site-specificSlide11
Maximum Allowable Industrial Loadings (MAILs)Not-to-exceed pollutant mass to plant from nondomestic sources
MAHLSlide12
Collection System Limitations CSLs)Not-to-exceed pollutant concentration to sewer
Calculated via scientific literature and experienceFlow obstructionFire/explosionToxic fumesStructural corrosion

IWC ImplementationPretreatment currently required, where necessary, by Sewer Use Ordinance
Integrate into existing trucked waste policyRedefine “transported” wasteUpdate procedures with new technical basisAlready includes cost recovery provisionsAlready subject to MDEQ approval and auditsSlide14
IWC ProceduresSlide15
IWC ProceduresSampling/analysis of POCs (by Generator)
Set maximum allowable flow rate (by MAWTF) Slide16
IWC ProceduresDischarge plan (by Generator); must be satisfactory to MAWTFSlide17
IWC ProceduresApproval (by MAWTF) Slide18
IWC ProceduresAcceptance (by Generator)Slide19
IWC Cost RecoveryFees for process wastes
$0.10 per gallon (local) $0.13 per gallon (non-local)Fees for groundwater remediation disposal and rinse waters$0.0914 per gallonGenerator responsible for sampling/analysis and any transportation costsSlide20
So Far, So GoodReasonable manpower and cost burdenMinimal effect on operations, discharge quality, and sludge quality
Improved communication between MAWTF staff and nondomestic usersNondomestic discharges yet to be regulatedHospital Slide21
PerspectiveEven if no IPP, responsible for protecting:
Collection systemTreatment plantWorker health/safetyInformal IWC can be an effective alternative for smaller communities with limited resources Technical basis similar to IPP
Need site-specific headworks loading evaluationSlide22
Thank you.
