(1) General. Each POWTS design shall include a management plan for maintaining the design performance and operational standards required for the particular system as required in this chapter. The management plan shall be a part of all Sanitary Permit applications. The plan shall include all necessary information which may include:

(a) Servicing schedules or frequencies of maintenance for removal of accumulated solids or by-products.

(b) Influent and effluent volume and their characteristics.

(c) Groundwater monitoring well locations.

(d) Monitoring well construction requirements and sampling procedures.

(e) Monitoring/sampling port location.

(f) Metering, sampling and monitoring schedules.

(g) Site vegetative cover maintenance.

(h) Load and rest schedules.

(i) Contingency plans for events involving component or operational failure.

(j) Alarms or other devices provided to alert the owner that the system is malfunctioning

(k) Odor and nuisance control.

(l) All maintenance requirements including a description of the process and frequency of maintenance for all system components.

(m) The requirement of reporting maintenance or service, its frequency and identifying the reporting agent and that the County shall receive a copy of the report within 10 days of service.

(n) Start-up and operation requirements for a particular system.

(o) Identification of common household products that should not be introduced into a POWTS dispersal system.

(p) Identification of common household wastewater practices and habits that typically cause performance problems for a POWTS dispersal system.

(q) Abandonment procedures the owner shall follow in the event a POWTS fails and is permanently taken out of service. Abandonment must be done in accordance with Comm. 83.33, Wisconsin Administrative Code.

(r) Warnings of the dangers associated with POWTS especially all treatment tanks.

(s) Listings of the phone numbers and names of the POWTS installer, all service contractors, septage pumping contractor and the local permit issuing authority.

(t) Any other pertinent information deemed specific for a particular POWTS or required by the Sanitarian.

(u) Any mechanical aerobic treatment units or other pre-treatment units requiring annual or semi-annual maintenance by a POWTS maintainer shall be noted in the management plan.

(2) Monitoring Influent and Effluent Load.

(a) The influent loads discharging to a POWTS and/or the effluent loads from a POWTS shall be sampled and evaluated for contaminants as required in the approved package or design or by conditional approval from the State. Results of the analysis shall be reported to the County by the POWTS owner or their designated agent as specified in the management plan. Kenosha County reserves the right to require sampling and monitoring criteria and any necessary devices to perform this in addition to the requirements stated in the plan approval from the Department of Commerce.

(b) The County may require monitoring of additional parameters not originally included in the management plan.

(c) The samples collected for monitoring shall be handled in accordance with the requirements of the approved management plan or when no procedure is specified, in accordance with published standard methods.

(3) Contingency Plans.

(a) All applications for a Sanitary Permit shall include a contingency plan that describes the procedures that must be followed at any time the POWTS fails and cannot be repaired.

(b) If a secondary or replacement area has been identified on the soil and site evaluation report and on the site plan of the applications, then the site shall be so noted in the contingency plan. There shall be some language instructing the owner to preserve this site thus avoiding soil disturbance and utilizing the area for structures or driveway or parking areas.

(c) The use of a holding tank as a means of resolving a failed condition of a POWTS will have a very limited application and therefore should not be mentioned in a contingency plan unless it is a viable last resort possibility in accordance with this ordinance.

(d) The plan should also include any temporary or interim solutions necessary for the owner to perform to insure that the system will not discharge untreated or partially treated effluent during any component malfunction. [Code § 15.06-2, 2018.]
