				  discharge to surface waters shall monitor as follows and report the monitoring
				  results on application forms.
(a) Samples
				  shall be as representative of normal effluent quality as possible.
(b) Minimum monitoring requirements for each
				  type of point source that conveys a wastewater discharge are specified in Table
				  1.

								  vinyl ether, dioxin, asbestos and TOC (total organic carbon); pollutants listed

1 Primary industries
				  are required to test only those GC/MS fractions that are specified in 40 CFR
				  122, Appendix D, revised Table 1.
(c) Persons collecting multiple samples for a pollutant shall
				  allow at least a 24 hour interval between consecutive samples.
(d) The department may require the applicant
				  to monitor 11 times for chloride for major municipal discharges or minor
				  municipal discharges when the source of wastewater is from hard water
				  communities, or for industrial process wastewater discharges from dairies,
				  canneries, meat processors, water utilities that utilize ion-exchange water
				  softening and other industrial categories expected to have high chloride
				  levels.
(e) The department may
				  require the applicant to monitor 4 times for the metals arsenic, cadmium, lead,
				  nickel and zinc for major municipal discharges or minor municipal discharges
				  when levels of those metals measured in the wastewater treatment system sludge
				  from a facility are abnormally high compared with other similar facilities in
				  the state.
(f) The department may
				  require the applicant to monitor for the dioxin and furan congeners listed in
				  s.
				  NR
				  106.115(2) for a major municipal
				  discharge or minor municipal discharge when sources of wastewater include a
				  pulp or paper mill or both, a leather tannery, a petroleum refinery or an
				  organic chemical manufacturer or for a primary industrial discharge if the
				  industry is a pulp or paper mill or both, a leather tannery, a petroleum
				  refinery or an organic chemical manufacturer.
(g) The department may require monitoring for any other pollutant
				  not specified in Table 1 if its presence could be reasonably expected based on
				  wastewater sources.
(h) An
				  applicant for permit reissuance may apply test data collected to fulfill
				  current permit required monitoring or data collected for other reasons to
				  fulfill these requirements if:
1. No more
				  than 5 years have elapsed since the monitoring; and
2. No operational changes have occurred since the
				  monitoring.
(i) Unless
				  the monitoring is required by federal regulations, the department may exempt
				  applicants from some or all of the monitoring requirements in this subsection
				  for reasons including, but not limited to, any of the following:
1. Parameters such as flow, hardness or pH measured in
				  the discharge or receiving water would result in proposed effluent limitations
				  for a pollutant much greater than anticipated discharge levels for that
				  pollutant, based upon measurements from similar discharges.
2. Proposed effluent limitations for a
				  pollutant would be much greater than anticipated discharge levels for that
				  pollutant, based on previous measurements made since significant facility
				  changes have occurred.
3. Previous
				  monitoring from similar facilities indicate the absence of significant
				  quantities of a pollutant or class of pollutants. NR
