(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 Chapter 419, Section 6.D(1), 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.

(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 405.D. 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 compounds listed in Appendix 405.D. These parameters must be analyzed for total concentrations using methods in SW 846.
