1. For the purposes of this chapter, wastes from residential and nonresidential sources shall not be mixed. Wastes from an industrial/commercial source shall not be mixed with wastes of any type from another location. Portable toilet and food service establishment grease trap wastes may be mixed with similar wastes from different locations. Residential wastes from several sources may be mixed as long as each source is identified.
2. Any tanks used for hauling waste to the WRF or equipment that comes in contact with waste shall not be used for hauling hazardous wastes or hazardous substances, as defined in Iowa Code Section 567.1 et seq., Chapter 131 of the Iowa Administrative Code and in 40 CFR 261, or other wastes which may be detrimental to the POTW, the receiving waters, or the health of WRF employees, private contractors, or the public.
(Ord. 2120 - Sep. 22 Supp.)
1. Under this division, disposal of wastes at the WRF shall be carried out in accordance with pretreatment standards and requirements established by Federal, State, County and City governments including categorical standards developed for the waste generator's industrial category. The WRA director may reject wastes from waste haulers who do not comply with this section or with any other applicable section of this division. Waste haulers shall not deliver wastes to the WRF, or to any other disposal location approved by the WRA director which are:
B. Hazardous wastes or hazardous substances as defined in 40 CFR Part 261 or 567 IAC, Chapter 131.
C. Originate from mineral oil unless first treated to remove the oil and grease.
D. Not completely identified or are from industrial/commercial sources that are not approved by the WRA director as required in Section 102.06.
E. Mixed in a manner prohibited in Section 102.07.
F. Wastes other than residential from outside the WRA, except through requests to the WRA director.
2. All disposal transactions at the WRF shall consist of waste haulers scaling in and scaling out on the WRF scales system. Prior to discharging any contents from their vehicle, a waste hauler shall:
A. Collect onsite at the WRF a sufficient sample of the waste material onboard.
B. Test and record the pH and immediately report any results that do not meet disposal limits as listed in Section 100.08.
C. Document on the WRF manifest all contents of the waste load including waste type, source information, and any other information consistent with identification and tracking of wastes as required in Section 102.06.
D. Request and obtain approval from WRF Operations to begin unloading at the WRF digesters.
(Ord. 2120 - Sep. 22 Supp.)
The WRA Director may reject any hauled waste load that violates or is suspected of violating the requirements of this chapter or other applicable chapter of this Code of Ordinances or that fails to meet any other guidelines established by the WRA Director to protect personnel, equipment, and the WRF.
Waste haulers must:
1. Remove rejected waste from the WRF.
2. Immediately remove any additional wastes contaminated by the rejected waste while contained at the WRF prior to introduction into the sewer.
3. Properly dispose of all rejected wastes in accordance with State and Federal law.
4. Provide the WRA Director with a written statement, signed by the waste hauler license holder, stating the location, date, and time the rejected load was disposed of. The statement is due within five calendar days after the waste is rejected.
A vehicle used to haul rejected wastes shall not thereafter be allowed to dispose of additional wastes at the WRF until the statement required by this section is delivered to the WRA Director.
1. A treatment fee shall be charged per pound of hauled waste disposed of at the WRF and assessed based on the waste type, pollutant loading, approved disposal location, and location of the source material. The fee for treatment shall include electrical, chemical, labor, equipment, fuel, maintenance, and any capital costs associated with the treatment processes utilized. The treatment fee shall reflect a total cost per gallon or per pound of hauled waste equaling the sum of the total cost of pollutants per gallon or per pound plus, if applicable, total cost of flow per gallon, based on: (1) the parameters of chemical oxygen demand (COD), estimated biochemical oxygen demand (BOD), total suspended solids (TSS) and/or total solids (TS), volatile solids (VS), total Kjeldahl nitrogen (TKN), oil and grease (O&G), and, if applicable, total phosphorus (TP) contained in trucked waste to the WRF; (2) net weight of the wasteload in pounds; and (3) the treatment surcharge component rate per pound of pollutant as found in section 100.17 of this division. Wasteloads disposed of at an unapproved location at the WRF, or containing pollutant concentrations different from typical pollutant concentrations or from original disclosures made during the wasteload approval process, may be subject to the following additional costs: treatment fees, charges, or fines may also be applied pursuant to Section 100.17.
2. Treatment costs shall be reviewed and updated annually per the U.S. Bureau of Labor Statistics Consumer Price Index. The WRA shall provide 30 days' notice prior to assessing updated disposal rates with such notices posted, at a minimum, on the WRA website. The treatment fee for loads originating outside the corporate limits of the WRA participating communities shall be 1.5 times the fee for loads originating within the WRA participating communities unless otherwise approved by the WRA director.
3. Wasteload disposal weights shall be computed and recorded at the WRF truck scales and the resulting treatment fees shall be paid by the waste hauler or waste generator, at the WRA's discretion, on the basis of monthly billings by the finance department. Limits of credit shall not exceed 60 days. Abuse of such credit shall be grounds for liability on the waste hauler's or waste generator's bond and for refusal of disposal services to any waste hauler or waste generator under this chapter.
4. Waste haulers and waste generators may elect to have their routine waste streams tested for actual concentration at their expense as set forth in Section 100.18 and as approved by the WRA director. When a waste hauler or waste generator has elected to test for actual concentration, the treatment fee will be based on the actual concentration whether it be higher or lower than the average concentration treatment fee. Said testing will be done at least semi-annually or as required by the WRA director.
(Ord. 2120 - Sep. 22 Supp.)
1. The Director or such other designated officers or officials with enforcement authority as provided in Section 102.11 are authorized to issue a notice of violation imposing an administrative penalty upon any person who fails to perform an act required by this chapter or who commits an act prohibited by this chapter.
2. The administrative penalty for such violations shall be as provided in the schedule of administrative penalties adopted by the Council by resolution.

The WRA shall maintain a record of all violations, administrative penalties charged or other enforcement actions taken.
