POLLUTANT LIMITS
(a) Bulk residuals or residuals that are sold or given away in a bag or other container shall not be applied to the land if
the concentration of any pollutant in the residuals exceeds the ceiling concentration for that pollutant as stipulated in the
following (i.e., on a dry weight basis):
Pollutant
Arsenic

(b) Bulk residuals shall not be applied to the land if the land application causes the exceedance of the cumulative
pollutant loading rate for any pollutant as stipulated in the following (i.e., on a dry weight basis):

(1)
A person shall determine compliance with the cumulative pollutant loading rates using one of the
following methods:
(A)
by calculating the existing cumulative level of pollutants using actual analytical data from all
historical land application events of residuals not otherwise exempted by this Paragraph or
(B)
for land on which land application events of residuals has not occurred or for which the data
required in Rule .1105(b) is incomplete, by determining background concentrations through
representative soil sampling.
(2)
When applied to the land, bulk residuals shall be exempt from complying with this Paragraph as long
as they meet all of the following criteria:
(A)
the monthly average concentrations stipulated in Rule .1105(c) of this Section.
(B)
the pathogen reduction requirements stipulated in Rule .1106(b) of this Section, and
(C)
the vector attraction reduction requirements stipulated in Rule .1107 of this Section.
(c) Bulk residuals shall not be applied to a lawn, home garden, or public contact use site nor shall residuals be sold or
given away in a bag or other container for application to the land if the concentration of any pollutant in the residuals
exceeds the concentration for that pollutant as stipulated in the following (i.e., on a dry weight basis):
Pollutant
Arsenic
Cadmium
Copper

(d) Bulk residuals shall not be placed in a surface disposal unit if the concentration of any pollutant in the residuals
exceeds the concentration for that pollutant as stipulated in the following (i.e., on a dry weight basis):
Distance from Surface Disposal Unit

(meters)
0 to less than 25
25 to less than 50
50 to less than 75
