Section 7103-166.0 - Constituent Characterization

166.1 Waste products to be utilized in land application projects may range from relatively clean by-products such as those from certain food processing industries to those which are potentially toxic above certain threshold limits and would require special considerations. As such it is important that the composition of the waste product be determined.

The degree of analysis required is dependent on the ability of the applicant to identify the composition of the waste product. By-products whose composition can be clearly determined through source identification may only need to be analyzed for nutrient status, providing it can be shown that the constituents identified in Part III, B, Subsection 117.2 of these regulations are either absent or at low enough concentrations that they pose no significant environmental or public health risks. However, waste products whose composition is difficult to consistently ascertain will be required to be analyzed for the constituents cited in Part III, B, Subsection 402(2) (168.0) of these regulations.

166.2 The waste product generator shall submit to the Department a chemical analysis of the waste product in accordance with Part III, B, Subsection 402(2) (168.0) of these regulations every three months following permit issuance for 402 (2) (b) (168.0) unless the Department approves a different schedule in the permit. The parameters for analysis will be developed based upon the critical or controlling constituents determined through the characterization of the by-product.

166.3 In no case shall the cumulative metals loadings exceed the levels set forth in Part III, A, Table 2 of these regulations. The applicant shall utilize table 2 in conjunction with Section 500 to calculate the potential site life for the constitute metals.

166.4 The waste product generator shall perform and submit to the Department and landowner additional analyses if there has been a significant change (greater than 25%) in the quality of the waste product from the original characterization.
