Rule 2409. (1) A person shall not apply bulk biosolids or biosolids sold or given away in
a bag or other container to the land if the concentration of any pollutant in the biosolids
exceeds the ceiling concentration for the pollutant in table 1 of this rule.
(2) If bulk biosolids are applied to agricultural land, a forest, a public contact site, or a
reclamation site, then the applicator shall comply with either of the following provisions:
(a) The cumulative loading rate for each pollutant shall not exceed the cumulative
pollutant-loading rate for the pollutant in table 2 of this rule.
(b) The concentration of each pollutant in the biosolids shall not exceed the concentration
for the pollutant in table 3 of this rule.
(3) If bulk biosolids are applied to a lawn or a home garden, then the concentration of
each pollutant in the biosolids shall not exceed the concentration for the pollutant in table
3 of this rule.
(4) If biosolids are sold or given away in a bag or other container for application to the
land, then the distributor shall comply with either of the following provisions:
(a) The concentration of each pollutant in the biosolids shall not exceed the concentration
for the pollutant in table 3 of this rule.
(b) The product of the concentration of each pollutant in the biosolids and the annual
whole biosolids application rate for the biosolids shall not cause the annual pollutant-
loading rate for the pollutant in table 4 of this rule to be exceeded. The procedure used to
determine the annual whole biosolids application rate is specified in R 323.2417.
