Users shall provide wastewater pretreatment as necessary to comply with these City Regulations and shall achieve compliance with all categorical pretreatment standards, local limits, best management practices and the prohibitions set out in Sections 23B-8 and 23B-9 of these City Regulations within the time limitations specified by the EPA, the State, or the Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Director for review and shall be acceptable to the Director before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the City under the provisions of these City Regulations. Any subsequent alterations or additions to such pretreatment or flow-control facilities shall not be made without due notice to and prior approval of the City. If inspection of pretreatment systems and devices by authorized personnel of the City reveals such systems are not installed or operating in conformance with the plans and procedures submitted to the City or are not operating in compliance with the effluent limitations required by the City, the user shall make those modifications necessary to meet City requirements.
(Ord. 1911, 7-17-2023)
A. 
Whenever deemed necessary, the Director or their designee may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of these City Regulations.
B. 
The Director or their designee may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
C. 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
D. 
The City may require a user to install at the user's expense, suitable monitoring facilities or equipment that allows for the representative sampling and accurate observation of wastewater discharges. Such equipment shall be maintained in proper working order and kept safe and accessible at all times to City personnel.
E. 
When more than one user is discharging into a common service line, the City may require installation of separate monitoring equipment for each user. When there is a significant difference in wastewater constituents and characteristics produced by different operations of a single user, the City may require that separate service lines, connections and monitoring facilities be installed for each separate discharge.
F. 
Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the City's requirements and all applicable construction standards and specifications.
G. 
To fulfill the purposes of these City Regulations, the City may order users of the City's POTW to maintain records and/or install and maintain similar facilities or equipment as described above.
H. 
Users who discharge process wastewaters determined by the City to contain pollutants necessitating continuous pH measurement to demonstrate compliance shall, subsequent to notification by the City, install a continuous recording pH meter as approved by the City. Such meters shall be installed, operated, and maintained at the user's own cost and expense. Such records generated by these meters shall be retained for three years and shall be made available to the City upon request.
I. 
If the City determines that a user needs to measure and report wastewater flow, the user shall install an approved flow meter. Such meter shall be installed, operated and maintained at the user's own cost and expense. Such records generated by this meter shall be retained for three years and shall be made available to the City upon request.
J. 
All instrumentation owned and/or operated by any user shall be calibrated and maintained according to manufacturer specifications.
K. 
Sand, oil and grease (SOG) interceptors or other approved pretreatment devices shall be installed when, in the opinion of the Director or their designee, they are necessary for the proper handling of wastewater containing excessive amounts of grease, oil, or sand; except that such interceptors shall not be required for residential users. All SOG facilities shall install a SOG interceptor. Such pretreatment devices shall not be shared or used by more than one user.
L. 
Grease interceptors shall be installed in all nonresidential facilities involved with the preparation, manufacturing, processing or serving of food, as described in Section 23B-16(E)(1)(a).
M. 
All required interceptors, sample ports, RV dump stations, associated plumbing, material requirements and operational requirements shall meet the City of Kalispell's pretreatment standards or requirements.
(Ord. 1911, 7-17-2023)
A. 
Each user with the potential to contribute prohibited substances shall provide protection from accidental discharge of prohibited materials or other substances regulated by this section. To prevent accidental discharge of prohibited materials, facilities shall be provided and maintained at the user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the IPC for review and shall be approved before construction of the facility. No user shall introduce industrial wastes into the system until accidental discharge procedures have been approved by the City. Review and approval of such plans and operating procedures shall not relieve the user from the responsibility to modify the user's facility as necessary to meet the requirements of this section.
B. 
In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the IPC of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and planned corrective actions or corrective actions already taken.
C. 
Within five days following an accidental slug discharge, the user shall submit to the IPC a detailed written report describing the cause of the slug discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, or any other damage to person or property or the environment; nor shall such notification relieve the user of any civil or criminal penalties or other liability which may be imposed by this division or other applicable law.
D. 
Each user shall permanently post on the user's bulletin board or other prominent place advising employees whom to call in the event of a slug discharge. Each user shall advise all employees who may cause or suffer such a slug discharge to occur of the emergency notification procedure.
E. 
The City shall evaluate whether each SIU, within one year of being designated as a SIU, needs a plan to control slug discharges. If the City decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:
1. 
A description of discharge practices, including nonroutine batch discharges;
2. 
A description of stored chemicals;
3. 
Procedures for immediately notifying the IPC of slug discharges, including any prohibited discharge with procedures for follow-up written notification within five days; and
4. 
If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training and the building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response, are required.
F. 
SIUs are required to notify the POTW immediately of any changes at their facility affecting the potential for a Slug Discharge. If the POTW decides that a slug control plan is needed, the plan shall contain, at a minimum, the elements described in subsection (E)(1) through (4), above.
