D.Specific Analytical Requirements for Agronomic Utilization Facilities. Solid wastes proposed for agronomic utilization must be characterized in conformance with the requirements of this section unless otherwise approved by the Department, based on specific characteristics. The frequency of sampling must be adequate to represent the residual or site conditions. Frequencies may be enumerated below or in chapter 419 of these rules. The groups of parameters that the generator may be required to analyze for depends upon the processes that generate the residual, inputs to that process and the intended use of the residual. Groups of parameters that the Department may require to be analyzed for by the generator or at sites where residuals are utilized include the following:

(1)Soil Nutrient Analysis

(a)Initial analysis. A complete soil nutrient analysis includes the following: pH; available phosphorus; available potassium; available calcium; available magnesium; cation exchange capacity (C.E.C.); percent C.E.C. saturation with potassium; percent C.E.C. saturation with calcium; percent C.E.C. saturation with magnesium; percent C.E.C. saturation with sodium; and percent organic matter. Available nitrogen may be required by the Department to be measured. It may be measured in the field using protocols such as the Pre-Sidedress Nitrogen Test.

(b)On-going analysis. A minimum of one composite topsoil sample per eight (8) acres of utilization area must be collected at the site prior to utilization each year that a residual will be land applied. Results of the analyses must be received and interpreted by the license holder prior to utilization. These results must be used as a factor in determining the amount of residual to be land applied.

(2)Initial Residual Analysis. The Department may require that generators test for the following parameters. The Department will determine testing requirements based on the proposed utilization program, an assessment of parameters likely to be in the residual, an evaluation of the chemical compounds known or suspected to be present in the waste stream from which the sludge or residuals originate, the processes used to generate the residual, the database of analytical results developed by the Department, and other factors as appropriate.

Initial analysis for target volatile organic compounds, target semi-volatile organic compounds, total PCBs, and dioxin are required for: sewage sludge generated by POTWs with an average daily flow greater than 2.5 millions of gallons/day; POTWs with pulp and paper, tannery, textile-related or other significant industrial wastewater inputs; POTWs required to enact an Industrial Pretreatment Program according to U.S. EPA regulations 40 CFR Part 403; and sludge or residuals from pulp and paper mills, tanneries, textile mills, and ash generators.

Initial analysis for target semi-volatile organic compounds, total PCBs, and dioxin are required for ash generators.

(a)Baseline Nutrients. All residuals must be analyzed for the following parameters: pH, percent dry solids, total volatile solids, Calcium, Magnesium, Iron, Chloride, Total Phosphorus, Total Potassium, Total Carbon, and Sodium.

(b)Nitrogen. Sewage sludge, papermill sludge, food wastes and other type 1B residuals must also be analyzed for Total Kjeldahl Nitrogen (TKN), Ammonia Nitrogen (NH4), Nitrate (NO3) and Nitrite (NO2)
