As to all vehicles and equipment used by a waste hauler, the licensee shall:
1. Prevent waste and wastewater from leaking, spilling, or discharging onto roads or rights-of-way.
2. Ensure proper construction and repair of the equipment to allow cleaning.
3. Maintain vehicles and equipment in an essentially rust-free and sanitary condition and appearance.
4. Display the business name as it appears on the waste hauler license in three-inch or larger letters on the left and right sides of the vehicle.
Hauled waste shall only be disposed at the WRF at the designated disposal station or as authorized by the Iowa Department of Natural Resources for land application. Waste haulers shall maintain the WRF designated disposal location in a clean and orderly condition to avoid noxious odors and unsanitary conditions. Hours of operation at the WRF disposal station shall be set by the WRA Director. In the event of emergency situations, special arrangements between the waste hauler and the WRA Director regarding disposal at an alternative disposal site shall be allowed to permit response to such emergency. Any violation of an Iowa Department of Natural Resources rule or regulation for land disposal of hauled wastes by a waste hauler shall be grounds for rejection of a hauled waste load in Section 8-3B-8 of this chapter by such waste hauler or shall be grounds for denial, suspension, and revocation of such waste hauler’s license in Section 8-3B-13 of this chapter.
1. Waste haulers must document the nature and origin of wastes collected and the site and method of disposal for wastes that are removed from any locations or are delivered to the WRF.
Such information shall be provided on a manifest form provided by the WRA and shall also include: a) the name and address of the waste generator(s), b) the type of waste collected, c) any other information consistent with identification and tracking of wastes. The WRA Director or their designee shall have the right to verify all information required by this section, including the right to measure, sample, and analyze any waste regulated by this chapter.
2. The waste hauler or waste generator shall obtain approval from the WRA Director or their designee prior to loading wastes originating from an industrial/commercial source unless prior approval is on record with the WRA. A hauled waste profile form prescribed by the WRA must be completed by the waste generator and submitted to the WRA Director or their designee for consideration for waste load disposal at the WRF.
Such profile form shall include information regarding the waste generator’s name, address, phone number, authorized representative, waste description, and product information, anticipated volume and frequency of disposals, waste transporter information, process waste characteristics including pollutant concentrations, declarations, certifications, and signature of authorized official.
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 FSE 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 I.C. § 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.
Under this chapter, 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 section of this chapter. Waste haulers shall not deliver wastes to the WRF, or to any other disposal location approved by the WRA Director, which are:
2. Hazardous wastes or hazardous substances as defined in 40 CFR Part 261 or 567 IAC., Chapter 131.
3. Originate from mineral oil unless first treated to remove the oil and grease.
4. Not completely identified or are from industrial/commercial sources that are not approved by the WRA Director as required in Section 8-3B-5 of this chapter.
5. Mixed in a manner prohibited in Section 8-3B-5 of this chapter.
6. Wastes other than residential from outside the WRA, except through requests to the WRA Director.
7. 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 on-site 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 8-3-10(2).
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 8-3B-5.
D. Request and obtain approval from WRF Operations to begin unloading at the WRF digesters.
1. The WRA Director may reject any hauled waste load that violates, or is suspected of violating the requirements of this chapter, or that fails to meet any other guidelines established by the WRA Director to protect personnel, equipment, and the WRF.
Waste haulers must:
A. Remove rejected waste from the WRF.
B. Immediately remove any additional wastes contaminated by the rejected waste while contained at the WRF prior to introduction into the sewer.
C. Properly dispose of all rejected wastes in accordance with State and federal law.
D. 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.
2. 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. Treatment Through Headworks:
A. 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 (B.O.D.), total suspended solids (TSS) or total solids (TS), volatile solids (VS), total Kjeldahl nitrogen (TKN), oil and grease (O and 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 8-3-20 of this chapter. 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 toSection 8-3-20(1).
B. The treatment fee for loads originating outside the corporate limits of the WRA participating communities shall be one and one- half times the fee for loads originating within the WRA participating communities.
2. Using Portion of Treatment Processes:
A. 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.
B. The treatment fee for loads originating outside of the WRA participating communities shall be one and one-half times the fee for loads originating within the WRA participating communities unless otherwise approved by the WRA Director.
3. Computation, Recording, and Payment of Fees. 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 the waste generator, at the WRA’s discretion, on the basis of monthly billings by the operating contractor. 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 division.
4. Testing of Loads. 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 8-3-20 of this chapter 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.
