      1.   Shall not discharge domestic wastes at any other point on the wastewater treatment system other than designated disposal facilities.

      2.   Shall not discharge any wastes to the POTW that are liquid, semiliquid, or solid waste (or combination of wastes), which because of quantity, concentration, physical, or chemical characteristics may:

         a.   Be toxic, corrosive, an irritant, a strong sensitizer, flammable or combustible, explosive, or otherwise capable of causing substantial personal injury; and/or

         b.   Pose a substantial hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise improperly managed, or is identified or listed as a hazardous waste as defined by the Colorado Department of Health in 6 CCR 1007-3, or as may be amended in the future.

      1.   Permitted wastes with prohibited or nonpermitted wastes in the same tank; and

      2.   Domestic wastes with nondomestic wastes in the same tank, except that mixing of domestic waste with nondomestic wastes from grease/sand interceptors or grease traps is authorized. (Ord. 99-163; Ord. 01-42; Ord. 10-82)

12.5.1002: MANIFEST SYSTEM:

   A.   Requirements For Manifest: Any liquid waste hauler must complete a liquid waste hauler manifest if:

      1.   The liquid waste hauler is pumping wastes from a grease/sand interceptor, grease trap or other appurtenance that is connected to the wastewater treatment system, regardless of whether the wastes are disposed at a designated disposal facility; or

      2.   The liquid waste hauler is pumping wastes from septic tanks, portable toilets or other sources of wastes that are not connected to the wastewater treatment system and the wastes are disposed at a designated disposal facility. (Ord. 99-163; Ord. 01-42; Ord. 10-82; Ord. 14-66)

12.5.1003: REPORTING REQUIREMENTS:

   A.   Self-Monitored Reports: The Chief Executive Officer shall establish all sampling and monitoring requirements as deemed necessary for the disposal of hauled liquid wastes to designated disposal facilities. All self-monitored reports shall include the certification specified in 40 CFR section 403.6(a)(2)(ii).

   B.   Reports Of Changed Conditions: The liquid waste hauler must notify the Chief Executive Officer, in writing, of any planned significant changes to the liquid waste hauler operations or system which might alter the nature of or quality of its wastewater prior to discharge to the POTW's designated disposal system.

      1.   The Chief Executive Officer may require the liquid waste hauler to submit the information as may be deemed necessary to evaluate the changed condition, including the submission of a new liquid waste hauler permit application.

      2.   The Chief Executive Officer may issue a liquid waste hauler permit or modify an existing liquid waste hauler permit in response to changed conditions or anticipated changed conditions.

   C.   Reports Of Potential Problems:

      1.   In the case of any discharge, including, but not limited to, accidental discharges, spills, discharges that are suspected to be of a waste type, characteristic and/or nature not specifically authorized under the permit, which may cause potential problems for the POTW, the liquid waste hauler shall immediately cease discharge and immediately notify the Chief Executive Officer of the incident. This notification shall include a description of the type of waste, characteristic, or other information that alerted the liquid waste hauler to the potential problem, volume discharged, and corrective actions taken by the liquid waste hauler.

      2.   Within five (5) days following the discharge, the liquid waste hauler shall submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the liquid waste hauler to prevent similar future occurrences. The notification shall not relieve the liquid waste hauler of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall the notification relieve the liquid waste hauler of any fines, penalties, or other liability which may be imposed. The Chief Executive Officer may waive this requirement if the liquid waste hauler fully complies with this notification requirement and the Chief Executive Officer determines that the incident is minor.
