(1) Unit of measure: calcium carbonate equivalent (CCE).
(2) The category “uncontaminated bark and wood” denotes woody plants with a high C:N ratio, such as bark, sawdust, ramial wood
chips, etc. “Non-woody plants” denotes plants that are not woody perennial plants (trees) such as vegetable residuals. Contaminated
examples of these residuals include wood treated with PCP or copper chromium arsenate or residuals that have come in contact with
livestock waste or human fecal matter.
(3) Analysis required for secondary biosolids, alone or combined with primary residuals.
(4) Analysis or calculation required for residuals treated with lime and for deinking residuals.
(5) Analysis required for municipal biosolids and residuals resulting from a treatment process for raw water or wastewater that uses
aluminum (Al) or iron (Fe) salts.
(6) Analysis required if the residuals are from a cardboard manufacturing process or any other process requiring the addition of boron.
(7) Analysis required for any residual from a municipal wastewater treatment process, textile mill or tannery, or from a pulp and paper
manufacturing process that uses an oxidizing chlorine in the pulping, bleaching or wastewater treatment process. For municipal and
paper mill biosolids, if analytical results are unavailable, assume that the residual contains between 18 and 50 ng TEQ/kg.
(8) Mixtures with agricultural lime are permitted. See Table 7.2.
(9) Analysis required if the ash comes from the incineration of paper mill biosolids or wood containing sodium chloride (contact with
seawater).
(10) Screening material and other residuals are excluded. See also Section 8.5 concerning foreign matter.
(11) Land application of unmixed abattoir manures does not require a CA. See Table 4.1.
(12) Analysis required for hog abattoirs.
(13) Analysis required if the compost is made from wood treated with PCP, textile mill or tannery residuals, certain types of ash (see note
9) or municipal solid wastes not separated at source (separation-composting process). In the case of composts from a sortingcomposting
process, if analytical results are unavailable, assume that the compost contains between 18 and 50 ng TEQ/kg.
(14) Parameters for analysis will be based on inputs and determined on a case-by-case basis. Biotests may be required (Section 8.2.3).
(15) Unit of measure: ng TEQ/kg, dry weight.
