(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 [iv] as amended up to July 1, 2014; 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)(c)Calcium Carbonate Equivalents. Woodash, lime mud, papermill sludge, lime-stabilized sewage sludge and other liming agents must also be analyzed for Calcium Carbonate (CaCO3) equivalents.(d)Total Inorganic Compounds. All residuals other than sewage sludge must be analyzed for the following total inorganic target compounds: Aluminum, Antimony, Arsenic, Barium, Boron, Beryllium, Cadmium, Calcium, Chromium, Cobalt, Copper, Iron, Lead, Magnesium, Manganese, Mercury, Molybdenum, Nickel, Potassium, Selenium, Silver, Sodium, Thallium, Vanadium, Zinc, and Cyanide. These parameters must be analyzed for using methods in SW 846.(e)Sewage Sludge Metals. Sewage sludge must be analyzed for the following total metals: Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium and Zinc. (f)Pathogens. Following treatment by one or more of the pathogen reduction standards in 06-096 CMR ch. 419, Appendix B, residuals which may contain human pathogens may require compliance testing for one or more of the following indicator parameters: Salmonella sp., Fecal Coliform, enteric virus, or Helminth ova.(g)Compost stability. Compost stability may be measured using one of the following methods: (i)Aerated Pile: The compost moisture content is adjusted to between 40 and 60%. The compost is then aerated and, with the ambient air above 45º F., formed into a pile no smaller than six feet in diameter and four feet high. The temperature is measured two feet into the pile. The stability class is determined for the compost based on the highest temperature difference between the compost and ambient temperature over the course of five days;(ii)Dewars Flask (Insulated Container). The compost moisture content is adjusted to between 40 and 60%. The compost is then aerated, and enclosed in an insulated vacuum flask connected to a continuous reading internal/external thermometer. The stability class is determined for the compost based on the highest temperature difference between the encapsulated compost and ambient temperature over the course of five days; or(iii)Respiration. The amount of CO2 generated or O2 consumed by a compost at a constant temperature and moisture is measured. Other methods for determining stability may be approved by the Department on a case by case basis.
(h)Salt Toxicity. Salt toxicity must be determined by measurement of electrical conductivity, plant toxicity testing, or other methods approved by the Department. (i)Target volatile organic compounds. All residuals other than woodash from woodash generators burning only wood waste must be analyzed for the target volatile organic compounds listed in Appendix C of this chapter. These parameters must be analyzed for total concentrations using methods in SW 846.(j)Target semi-volatile compounds. A complete analysis for target semi-volatile compounds includes the Acid/Base-neutral target compoundslisted in Appendix D of this chapter. These parameters must be analyzed for total concentrations using methods in SW 846.(k)Total PCBs. A complete analysis for total PCBs, including, but not limited to, the arochlors listed in Appendix C of this chapter. Total PCBs must be analyzed for using methods in SW 846.(l)Target pesticides. A complete analysis for target pesticides includes the pesticides listed in Appendix C of this chapter. These parameters must be analyzed for total concentrations using methods in SW 846.(m)Dioxins(i)A complete analysis for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), also referred to as dioxin(s) and dioxin-like compounds. Sampling and analysis must be performed in accordance with EPA method 1613, EPA method 8290, or another Department-approved method.(ii)toxic Equivalency Factors. The results of the residual analyses must be used to calculate total 2,3,7,8-TCDD equivalents using the Toxic Equivalency Factors (TEF) in Tables 405.1 and 405.2 , which indicate the relative toxicity of mixtures of dioxins, furans and dioxin-like compounds in relationship to the toxicity of 2,3,7,8-PCDD. To calculate the total 2,3,7,8-PCDD equivalents, multiply each detect by the corresponding TEF then add all results. Reported non-detects (ND) at the method detection limit will be considered equal to 0. The TEFs from Table 405.2 will be used to determine compliance with the dioxin standard in 06-096 CMR ch. 419. Both calculations must be reported to the Department. Table 405.1 -- Reporting Toxic Equivalency Factors

(n)Non-hazardous determination. Initial characterization of any residual proposed for agronomic utilization must include a determination that the residual is non-hazardous. This determination must be made either through TCLP testing or through calculation utilizing the methodology described in Appendix C of this chapter. (o)Other. The Department may require analysis for other parameters that, based on a description of the process generating the residual, may be in the residual in significant concentrations to adversely impact the utilization program. (3)Follow-up Residual Analysis. Follow-up sampling and analysis. The frequency of follow-up sampling and analysis will be established by license condition, and determined based on the initial analytical results for the residual, the Department's data base of analytical results, the potential for these compounds to be present in the material, and other factors as appropriate. Sewage sludge must be analyzed for total arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium and zinc at the frequency in Table 405.3 unless otherwise approved by the Department based on specific characteristics.
