Sec. 16.
(a) Characteristics of a biosolid or industrial waste product must be monitored as required in this section.
(b) The resulting analyses of such characteristics must be reported on both a wet weight and dry weight basis.
(c) Analyses of additional parameters may be required by the commissioner on a case-by-case basis to protect the environment or public health.
(d) Biosolid or industrial waste product that is to be applied to the land must be monitored each day of land application for percent total solids.
(e) Prior to land application, representative samples of biosolid or industrial waste product that is to be applied to the land shall be collected and analyzed at the frequency listed in Table 6 in subsection (f) for the following parameters:
(f) The results of the analysis in subsection (e) are valid for the applicable length of time listed in Table 6 as follows:
Table 6
| Frequency of Monitoring | |
| Amount of Biosolid or Industrial Waste Product1 (dry tons per 365 day period) | Frequency of Monitoring2 |
| Greater than 0 but less than 319 | 12 months |
| Equal to or greater than 319 but less than 1,653 | 3 months |
| Equal to or greater than 1,653 but less than 16,530 | 2 months |
| Equal to or greater than 16,530 | 1 month |
1For existing facilities, either the amount of biosolid or industrial waste product generated in the previous year or the amount of biosolid or industrial waste product received by a person who prepares biosolid or industrial waste product that is marketed or distributed for application to the land, dry weight basis. For new facilities, the amount determined by engineering estimates for generation of biosolid or industrial waste product for the specific new facility.
2For the purposes of this table, a month is a 30 day period.
(g) After the biosolid or industrial waste product has been monitored for two (2) years at the frequency in Table 6 in subsection (f), the person who prepares a biosolid or industrial waste product may request a reduced frequency of monitoring from the commissioner for pollutant concentrations in subsection (e)(2) and (e)(4).
(h) If the person who prepares a biosolid or industrial waste product can demonstrate to the satisfaction of the commissioner that the biosolid or industrial waste product has contained no detectable concentrations of PCBs for the previous two (2) years, the commissioner may reduce the required monitoring frequency for PCBs.
(i) For biosolid or industrial waste product that is a fixed volume, the person who prepares must, as specified in the permit, do either subdivision (1) or (2) as follows:
(j) For biosolid or industrial waste product that is not a fixed volume, the person who prepares must collect a composite sample and analyze for the parameters in subsection (i)(3). The composite sample must consist of a representative sample collected during each day of application. The composite sample must be collected over no more than thirty (30) days.
(k) Alternative equivalent methods meeting the requirements of this section may be used by the person who prepares a biosolid or industrial waste product if approved by the commissioner.
