(Ord. 38-1985) (mm) "MAHL (Maximum Allowable Headworks Loading)" means the maximum loading of a given pollutant that the POTW can accept without causing an exceedance of the most limiting of the following restrictions: (1) POTW upset limits (activated sludge and/or anaerobic digestion); (2) Pass -through limits (either NPDES discharge limits or water quality objectives); (3) Sludge disposal limits; (4) POTW design capacity limits. (nn) "MAIL (Maximum Allowable Industrial Headworks Loading)" means the maximum loading of a given pollutant that can be discharged by the sum total of all industrial users without causing an exceedance of the most limiting of the following restrictions: (1) POTW upset limits (activated sludge and/or anaerobic digestion); (2) Pass -through limits (either NPDES discharge limits or water quality objectives); (3) Sludge disposal limits; (4) POTW design capacity limits. (ddd) "QUALIFIED PROFESSIONAL" -- An individual who is trained and experienced in wastewater treatment, environmental compliance, or related fields as may be demonstrated by state registration, professional certification, experience, or completion of coursework that enables the individual to make sound, professional judgement regarding a facility's ability to comply with federal, state, and local wastewater rules and regulations. 54.39 PROHIBITED WATERS AND WASTE (k) Any of the following substances which shall be termed contaminates. It shall be unlawful for any person to discharge into a public sewer any such contaminates in any quantity where the level of the contaminates exceed the following average limits during a 24-hour period or a period of normal daily operations. (1) The concentration based limitations for the following contaminates apply at the point where the wastewater is discharged to the POTW. At the discretion of the Director, and under the following guidelines, the District may consider mass based limitations in addition to or in place of the concentration based limitations. (Ord. 93-2002) (a) The Director may consider mass based limits only in situations where a facility has tried in good faith to comply with our local concentration based limits using pretreatment or other legitimate means, and the attempt(s) is unsuccessful, and (Ord. 93-2002) (b) The District's POTW does have ample loading capacity for the parameter(s) of concern, and the consideration of mass based limits will not cause the POTW to exceed the Maximum Allowable Headworks Loadings at the POTW Headworks and the Industrial Users to exceed the Maximum Allowable Industrial Loadings at the POTW Headworks (Ord. 93-2002) (2) To maintain ample loading capacity for total copper, the District shall impose a non -uniform (Tiered) allocation method for total copper as described and quantified in this section. Tier 1 users are existing significant industrial users (SIUs) that do not have a copper limitation in their most recent wastewater discharge permit; these users can discharge wastewater with copper concentrations up to the demonstrated domestic and commercial background level. Tier 2 users are existing significant industrial users (SIUs) that do have a copper limitation in their wastewater discharge permit at the time of adoption of this ordinance; these users will remain at the existing local copper limit. Tier 3 is reserved for any new significant industrial user that will have a regulated copper discharge or any Tier 1 user that requests a permit modification to become a regulated copper discharger. New significant industrial users will be any industrial user required to obtain a wastewater discharge permit following adoption of this ordinance. Tier 3 copper limits will be calculated on a case by case basis, but at no time, will a Tier 3 copper limit be established to exceed the Maximum Allowable Industrial Headworks Loading or the Maximum Allowable Headworks Loading for copper at the POTW Headworks. Contaminate Concentration (mg) Arsenic (total) 0.09 Cadmium (total) 0.04 Chromium (total) 2.00 Copper (total) Non -uniform Allocation: Tier 1 Limitation (Domestic/Commercial Background Level) _ 0.15 mg/L Tier 2 Limitation (Existing Local Copper Limit) = 0.95 mg/L Tier 3 Limitation = Calculated on a case by case basis while remaining within the POTW's MARL and MAIL for copper. Cyanide 0.15 Lead (total) 0.20 Mercury (total) 0.0002 Molybdenum 0.55 Nickel (total) 1.10 Oil (hexane soluble or equivalent) Phenols Selenium (total) Silver Zinc (E) Signatory Requirement 100.0 (see paragraph 54.39(l) below) 1.00 0.22 0.40 3.00 The above reports shall contain the certification statement as set forth in 40 CFR 403.6(a)(2)(ii), and shall be signed by an authorized representative of the Industrial User, whom meets the signatory requirements as defined in 40 CFR 403.12(1 The amendment to this Ordinance shall be in full force and effect from and after its passage and adoption by the Common Council of the City of Richmond, Indiana. Passed and adopted this 15th day of October, 2007, by the Common Council of the City of Richmond, Indiana.
