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.

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.

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.

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.

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.

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.

(b) At least annually conduct a self-audit of activities conducted under the permittee's CMOM program to ensure CMOM components are being implemented as necessary to meet the standards in sub. (3) .

(6)   Exceptions. If the owner of a sewage collection system believes any component part or parts of the CMOM program requirements in this section are not appropriate or applicable for a specific sewage collection system, the CMOM program documentation required under sub. (5) shall fully explain why that component part is not applicable.

(7)   Compliance. Whenever a permittee's CMOM program does not meet the conditions established under this section, including the identification of and explanation for exceptions identified in sub. (6) , the department may require specific actions to establish and implement a CMOM program or component parts of a CMOM program. The specific requirements may be included as conditions in a permit.

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.

Microsoft Windows NT 6.1.7601 Service Pack 1 A geographic information system-based map of the sewage collection system meets this requirement. Microsoft Windows NT 6.1.7601 Service Pack 1 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.
