4New Categorical Standards Being Considered Healthcare IndustryUnused Pharmaceuticals“Best practices” (i.e., BMPs) being developed for Hospitals and Long Term Care FacilitiesDetails to be released withFinal 2010 ELG Plan
5New Categorical Standards Being Considered Airport Deicing OperationsEPA proposed standards in 2009High Ammonia wastewatersDental AmalgamVoluntary BMP Program Underway (ADA)EPA-proposed Standards expected 2011EPA final Standards expected 2012
6New Categorical Standards Being Considered Dental AmalgamADA-funded study indicated 50% of mercury entering POTWs can originate from dental.Well-maintained amalgam separators capture/recycle 95-99% of dental mercury.Use reduces free mercury in influent and biosolids (reports of 30-50% biosolids reduction).Use may have limited impact on reducing mercury elevated in POTW effluent.
8New Categorical Standards Being Considered Dental AmalgamIs anyone mandating use/maintenance of amalgam separators?(2008) 11 States and 20 local jurisdictions.Can I use local limits? (Yes)MWRA (Massachusetts, 350 MGD, 250+ SIU)Local limit established is 1 ppb (mg/L)Mercury sources: dentists 18%, industry 3%, Other 84%Reduction from medical sources in 5 years: 91%Annual penalties collected: ~$400k-100k
9Revisions to Existing Standards Being Considered OCPSF/Inorganics/Pharma Mfg – Parts 414/415/439Chlorine and Chlorinated Hydrocarbons (CCH) ManufacturingDioxins…forming from manufacture of :ethylene dichloride (EDC)vinyl chloride monomer (VCM)polyvinyl chloride (PVC)
10Revisions to Existing Standards Being Considered OCPSF/Inorganics/Pharma Mfg – Parts 414/415/439Chlorine and Chlorinated Hydrocarbons (CCH) ManufacturingMercury…increases due to new air pollution controls in mercury-cell process to manufacture :ChlorineCaustics
11Revisions to Existing Standards Being Considered Steam Electric Power – Part 423EPA-proposed rule expected 2012EPA-final rule expected 2014

16POTW Pretreatment Programs in SNC Region 4 closely reviewing State reportsElevated response from EPA where:POTW’s SNC continues despite State actionsPOTW’s SNC unresolved for two quarters or moreState requests EPA action
18FOG Programs and Pretreatment: Regulatory Basis What is an Industrial User?40 CFR 403.3(j)An industrial user is a source of indirect discharge.What is an Indirect Discharge?40 CFR 403.3(i)Introduction of pollutants into a POTW from any non-domestic source regulated under section 307(b), (c), (d) of the Clean Water Act.All non-domestic sources regulated by Pretreatment Standards require a control mechanism. 40 CFR 403.8(f)
19FOG Programs and Pretreatment: Regulatory Basis What is a Pretreatment Standard?40 CFR 403.3(l)Any categorical standards applicable to IUsAny prohibitions in 40 CFR 403.540 CFR 403.5(d)Local limits
20FOG Programs and Pretreatment: Regulatory Basis Specific Prohibitions (b)The following pollutants shall not be introduced into a POTW:403.5(b)(3)Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in Interference.403.5(b)(4)Any pollutant at a flow rate or concentration that will cause Interference with the POTW.
21FOG Programs and Pretreatment: Regulatory Basis What is a POTW?40 CFR 403.3(q)A treatment works owned by a municipality. This definition includes any devices or systems used in the storage, treatment, recycling, and reclamation of municipal sewage or liquid industrial wastes. It also includes sewers, pipes, and other conveyances that convey wastewater to a municipal treatment plant.What is Interference?40 CFR 403.3(k)A discharge, either alone or in combination with discharges from other sources, which both:(1) Inhibits or disrupts the POTW (see above); it’s treatment or operations, or sludge management(2) Causes a violation of any POTW permit requirement
22FOG Programs and Pretreatment: Regulatory Basis POTW permit requirements:…shall at all times properly operate and maintain……shall implement approved pretreatment program and Part 403…
23The receiving sewer serves a commercial fast-food area. Is the source of this pollutant an industrial user?
24Can this pollutant cause Interference with the POTW, and therefore a violation of Pretreatment Standards?
25Do the industrial users that supply this pollutant require a control mechanism by the POTW Pretreatment Program?
26FOG Programs and Pretreatment: Regulatory Basis What about residential sources? They are domestic sources…Control also necessary to meet common goals:Meet proper O&M condition of NPDES permitPrevent sewer overflow violationsAuthorities for controlling domestic FOG sources are local
