Section 200.065. Application monitoring requirements for discharges to surface waters.

 

(1)   Existing discharges. An applicant for permit issuance or reissuance with an existing 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. - See PDF for table - See PDF for table

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.

(2)   New discharge. The department may require a person applying for a new discharge permit to conduct pilot studies or other tests or provide effluent data from similar facilities to project pollutant levels in the proposed discharge.
