Section 323.2409. Application of limitations.

(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.

(5)     The following tables specify pollutant concentrations, loading rates,  and nutrient parameters:
