A GENERAL ORDINANCE AMENDING CHAPTER 54 OF RICHMOND
CITY CODE
WHEREAS, the City of Richmond Common Council (the "Council") adopted Chapter
54 providing for sewer usage for Richmond; and
WHEREAS, The City of Richmond's National Pollutant Discharge Elimination System
(NPEDS) permit requires a re-evaluation of our mandated pretreatment
program.; and
WHEREAS, Technical re-evaluation of our local limits demonstrate that a significant
increase to the current level of copper intake at our wastewater treatment
plant will jeopardize the City's viability of our land application program;
and
WHEREAS, it now becomes necessary to amend Chapter 54 et seq., for the continued
protection of the public health, safety, and welfare of the citizens of
Richmond; and
NOW, THEREFORE, be it ordained by the Common Council of the City of Richmond
that Chapter 54 of the Richmond Code is amended as follows:
SECTION
General Provisions
54.01 Purpose
54.02 Definitions
(11) "MAXIMUM DAILY DISCHARGE LIMITATIONS" -- Highest allowable
daily discharge concentration. (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

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.
