All permittees subject to this chapter, including the owners of satellite sewage collection systems and combined sewer systems, shall implement a capacity, management, operation, and maintenance program.(2) IMPLEMENTATION DEADLINE. The holder of a WPDES permit shall implement a capacity, management, operation and maintenance program under this section no later than August 1, 2016, or no later than an earlier date specified in the permit.(3) GENERAL STANDARDS. A CMOM program shall ensure the following general standards are met: (a) The sewage collection system is properly managed, operated, and maintained at all times.(b) The sewage collection system provides adequate capacity to convey all peak design flows.(c) All feasible steps are taken to eliminate excessive infiltration and inflow as defined in s. NR 110.03(13c), cease sanitary sewer overflows and sewage treatment facility overflows and mitigate the impact of such overflows on waters of the state, the environment, and public health. Note: When evaluating feasibility of alternatives, the department may consider factors such as technical achievability, the relationship between the control of storm water and the control of infiltration/inflow into the sewage collection system, costs and affordability of implementation and risks to public health, the environment, and welfare of the community served by the sewage collection system.
(d) A process is in place to notify the public and other directly affected parties of any incidents of overflows from the sewerage system.(e) Annual reports are submitted in accordance with the provisions of ch. NR 208.(4) COMPONENTS OF CMOM PROGRAM. (a)Goals. Major goals of the CMOM program shall be consistent with the general standards identified in sub. (3).(b)Organization. Persons who are responsible for implementing the CMOM program shall be identified including administration, management, and maintenance personnel or positions, lines of authority of such personnel or positions, internal and external communication responsibilities, and the person or persons who shall report all overflow events to the department and to the public according to s. NR 210.21(3) to (6).(c)Legal authority. Legally binding authorities, such as sewer use ordinances and service agreements, shall ensure the following: 1. Infiltration and inflow sources, including infiltration and inflow into building sewers, private interceptor sewers, or other such sources on private property, are subject to oversight and control, as necessary.2. New sewers and connections, including building sewers and private interceptor sewers are designed, constructed, installed, tested, and inspected to meet all applicable current engineering and construction standards.3. New and rehabilitated sewers, lift stations and other collection system components or appurtenances are installed, tested, and inspected to meet all applicable current standards.4. If applicable, sewage flows from municipal satellite or other privately owned sewage collection systems are, as necessary, monitored, and controlled. Notwithstanding all other provisions of this chapter, any publicly owned treatment works may establish specific requirements to regulate sewage flows from satellite sewage collection systems.5. Solid or viscous pollutants, such as fats, oils, and greases, are not discharged into the sewage collection system in amounts that will cause or contribute to obstruction to the flow in the sewer. Note: This provision is similar to that contained in s. NR 211.10(2) (c).
6. Procedures are in place to implement enforcement actions for non-compliance with established legal authorities.(d)Operation and maintenance. Operation and maintenance equipment, activities and protocols, including identification of personnel or positions responsible, shall, as appropriate and applicable to the system, include the following:1. Adequate maintenance facilities and equipment including equipment and replacement parts inventories, especially critical replacement parts.2. A map of the sewage collection system. Note: A geographic information system-based map of the sewage collection system meets this requirement.
3. A management system for the collection and use of information to identify and prioritize appropriate operation and maintenance activities, including identification of structural deficiencies and implementation actions to address such deficiencies.4. A description of routine preventive operation and maintenance activities such as inspections, televising, cleaning, flow monitoring, root removal, and rehabilitation. Note: Protocols for cleaning sewers should include methods for disposal of sand, grit, and other solids in a manner that will not contaminate surface water or groundwater or create a risk to public health. Proper disposal of such material includes, but is not limited to, placement in a licensed solid waste landfill, return of the material to the headworks of the sewage treatment facility or placing the material in a properly designed and operated treatment unit.
5. A program to periodically assess the capacity of the sewage collection system and treatment facilities.6. The identification of activities to prevent and correct frequent and recurring building backups caused by sewage collection system hydraulic constraints.7. Appropriate training on a regular basis.(e)Design and performance standards. The following standards and procedures shall be established or adopted to maintain control over the design, construction, and inspection of the sewage collection system, including building sewers and private interceptor sewers on private property: 1. Standards and specifications for the design and installation of new sewers, lift stations, and other appurtenances and for rehabilitation and repair projects. Note: Chapter NR 110 must be followed when designing and constructing sewage collection systems. Chapter SPS 382 must be followed when designing and constructing plumbing. Permittees may have supplemental standards and requirements specific to community needs.
2. Procedures and requirements for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects.(f)Overflow emergency response plan. An overflow emergency response plan shall identify measures to protect public health and the environment from sanitary sewer overflows and sewage treatment facility overflows and building backups caused by excessive flow or other hydraulic constraints in the sewage collection system and shall include protocols to ensure the following: 1. Responsible personnel are made aware of all overflows.2. There is a prompt and appropriate response to and investigation of all overflows to protect, to the extent possible, water quality, the environment, and public health.3. There is appropriate reporting and notification as required under s. NR 210.21(4) to (6). The overflow emergency response plan shall identify the public health and other officials who will receive notification and identify the protocols and procedures for notification of the public who may be affected by an overflow. Whenever there is a significant or potentially significant risk to public health, public notification shall include personal contacts with persons who may be at risk from the affects of the overflow. Note: To the extent practicable, local public health and other responsible officials should be consulted in developing those portions of the overflow emergency response plan that involve reporting and notification of those officials. Permittees should consider use of the following communication methods when establishing public notification protocols: electronic mail or other electronic communication, posting on internet web sites, notification of local print and media (television, radio) outlets, posting notices on public buildings, personal notification, etc.
4. Appropriate personnel are aware of and follow the plan and are appropriately trained.5. Emergency operations appropriate to the event are implemented.(5) CMOM PROGRAM DOCUMENTATION AND AUDIT. All permittees subject to the requirements of this section shall do all of the following:(a) Develop and maintain written documentation of the CMOM program components. Such documentation shall be available for department review on request. The department may request a permittee to provide this documentation or prepare a summary of the permittee's CMOM program at the time of application for reissuance of a WPDES permit. Note: Annual verification of CMOM program documentation is required under ch. NR 208.
