industrial waste to a land treatment system unless the land application or
discharge is authorized by a WPDES permit.

university located within this state provided the following requirements are
met:
1. The net site area, excluding site
borders and buffer strips, does not exceed 4 acres;
2. The available nitrogen, chloride and heavy
metal additions averaged over the total plot area may not exceed the rates
specified by the department in ch. NR 204 for municipal sewage sludges or those
identified in the literature as being toxic to specific plants or plant
groups;
3. The site is developed,
operated, monitored and maintained in a safe, nuisance free manner;
and
4. Copies of the research
proposal are submitted to the department in advance of initiation of the
research and any reports and publications on the research are provided to the
department.
