(6) RESIDUE CHARACTERIZATION. (a) An operator of a municipal solid waste combustor with a design capacity of 10 tons per day or greater shall test its residue quarterly the first year after an approval has been issued. After the first year of quarterly testing the residues shall be tested on an annual basis, except as provided in par. (m). The testing program listed in Table 1 shall be applied to all samples collected as required by sub. (5) (a) to (d). The department may require dioxin and furan testing, if circumstances warrant. Test results shall be submitted to the department with the annual report specified under sub. (8).(b) An operator of a municipal solid waste combustor with a design capacity of less than 10 tons per day shall:1. Test residue samples collected under sub. (5) (f) in accordance with the testing program in par. (g).2. Test its residue annually beginning the first June after an approval has been issued using the testing program listed in Table 1 for all samples collected under sub. (5) (f). The department may require dioxin or furan testing, if circumstances warrant.3. Submit test results to the department with the annual report specified under sub. (8).4. Comply with all of the other provisions of this section.(c) A leachate sample from the monofill where the residue is disposed of may be substituted for the synthetic precipitation leaching procedure, EPA Method 1312, after the initial 4 rounds of testing. The leachate sample shall be tested for all of the parameters listed in Table 1, Section III, unless a reduction in the number of parameters tested for has been approved by the department. The municipal solid waste combustor using the leachate substitute shall be responsible for the testing. If significant levels of any of the listed parameters are detected in the leachate tested from a monofill that receives multiple sources of residue, the department may require all contributing municipal solid waste combustors to perform leach testing of their residue using EPA Method 1312.

(d) The operator of the municipal solid waste combustor may apply to the department at the end of the initial 4 rounds of testing for elimination of those parameters listed in Table 1, Section II which do not appear in its residues at significant levels.(e) The provisions of this subsection do not supersede the testing requirements for the 8 heavy metal parameters listed in par. (g) using the toxicity characteristic leaching procedure, EPA Method 1311.(f) During the scheduled testing period, if any parameter in the bulk analysis is not detected at or above the specified detection limits, then that parameter may be eliminated from further leach testing for that test period.(g) An operator of a municipal solid waste combustor shall test its residue for the parameters listed in this paragraph quarterly and within 2 weeks of completing initial startup and shakedown, and after any significant changes in plant design, operation or waste input that significantly affects or changes the residue characteristics by using the toxicity characteristic leaching procedure, EPA Method 1311. Multiple samples may be tested separately and the results combined to obtain an arithmetic mean for each parameter. The operator shall immediately notify the department if test results indicate that any of the following limits are exceeded: Note: Method 1311 is in Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA Publication SW-846, third edition, November 1986, as amended by Updates I in July 1992, II in September 1994, IIA in August 1993, IIB in January 1995, III in December 1996 and IIIA in April 1998.

(h) If any of the limits in par. (g) are exceeded, the operator may elect to complete confirmatory testing on the retained sample within 2 weeks of receiving the initial results. If the operator elects to perform the confirmatory testing, only the constituents exceeding the limits will require testing.(i) If any of the limits in par. (g) are exceeded and confirmatory testing under par. (h) is not completed, or if the test results of par. (h) confirms the exceedance of the limits for the parameters listed in par. (g), the residue may be treated to reduce leachable constituents below the threshold values, prior to disposal, or the residue shall be managed in accordance with chs. NR 660 to 679 until a significant change to the facility design, operation or waste input can be demonstrated which produces consistent test results that meet the specified limits.(j) If a significant change to the waste input can be demonstrated, the operator shall confirm this change by completing confirmatory testing of one new sample taken in accordance with sub. (5). In cases where the contributing waste input cannot be isolated, consistent test results meeting the specified limits shall be obtained from monthly testing according to the requirements of par. (g) for a minimum of 3 months. Only the constituents exceeding the limits in par. (g) will require retesting under this provision.(k) If none of the limits in par. (g) are exceeded or the confirmatory testing defined in par. (h) is below the specified limits in par. (g), the residue may be disposed of in a single composite lined monofill in accordance with the provisions of s. NR 504.11(2) (a). In cases where limits in par. (g) were exceeded during initial testing, but were not exceeded in the confirmatory testing, additional testing in accordance with par. (g) shall be performed monthly for a minimum of 3 months to confirm that the initial exceedances were not representative of the residue characteristics. Only the constituents exceeding the limits require retesting under this provision. If there are any exceedances during this 3 month period, the residue shall be managed in accordance with the provisions of chs. NR 660 to 679.(L) All treated residue shall be tested according to the requirements of this section.(m) The department may require different testing frequency and parameters, if circumstances warrant.
