APPLICABILITY. Any person who treats or
generates sludge, applies sludge to land or places sludge in a landfill shall
comply with the requirements in this chapter.
In general, this chapter applies to the
1. The use and disposal of sludge
and grit and screenings generated by any domestic wastewater treatment
The quantity and quality
of sludge that is applied to land or landfilled. This includes sludge which is
combined with another material. The other material may include industrial
sludge, other municipal sludge, septage, manure, any material used for mixing
or other wastes with which the sludge forms a composted material.
Note: Note: Chs.
NR 502 and
518 may also apply to processing
and use of solid waste and sludge mixtures.
3. The land on which sludge is applied and
any landfill which receives the sludge.
In general, these rules do not govern the
1. The use or disposal of sludge
which is a hazardous waste as defined by ch. NR 660.
2. Septage as defined in ch. NR 113. This
does not exempt centralized septage treatment facilities which are required to
obtain a WPDES permit.
that is incinerated.
4. Bulk or
bagged material which is derived from exceptional quality sludge. This is
material which is derived after the generator distributes exceptional quality
sludge. It does not include a bulk material which becomes exceptional quality
after mixing or treatment with non-exceptional sludge.
5. Industrial sludge, including sewage sludge
generated during the treatment of industrial wastewater that is combined with
domestic sewage originating at that industrial facility.
Sludge with PCB concentrations greater
than 50 mg/kg on a dry weight basis, unless this sludge is applied under a
management plan approved by U.S. environmental protection agency (EPA) region V
pursuant to 40 CFR part 761
generated through the treatment of drinking water.
Note: The regulation of the incineration of sludge under 40
CFR part 503 will be administered by the U.S. environmental protection
RESPONSIBILITY. A facility that generates
sludge is ultimately responsible for the handling, transporting, storage and
land application or disposal of the sludge and grit and screenings. A generator
is responsible for compliance with its WPDES permit and all applicable
provisions of this chapter. In the event a generator sends its sludge to
another person for final land application or disposal and that person alters
the characteristics of the sludge by mixing it with other wastes or substances
or by treating it in some other manner, then the person who receives the sludge
shall also be considered a generator and shall assume primary responsibility
for compliance with this chapter. If a generator gives the sludge to another
person to land apply, but that person does not alter the characteristics of the
sludge, then that person is also responsible for complying with applicable
provisions in this chapter, such as the land management practices specified in
