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)
