Current through Register Vol. 39, No. 6, September 16, 2024

(a) Residuals shall not be land applied if the concentration of any pollutant in the residuals exceeds the ceiling concentration for that pollutant as stipulated in the following on a dry weight basis:

Pollutant

Ceiling Concentration

(milligrams per kilogram)

Zinc

7,500

(b) Class B residuals shall not be land applied if the application causes the cumulative pollutant loading rate, on a dry weight basis, to be exceeded for any pollutant as stipulated in the following:

Pollutant

Cumulative Pollutant

Loading Rate

(kilograms per hectare)

Arsenic

41

Cadmium

Compliance with the cumulative pollutant loading rates shall be determined using one of the following methods:

(1) by calculating the existing cumulative level of pollutants using analytical data from all historical land application of residuals not otherwise exempted by this Paragraph; or

(2) for land on which land application events of residuals has not occurred or for which the data required in Paragraph (b) of this Rule is incomplete, by determining background concentrations through representative soil sampling.

(c) Class A residuals shall not be applied if the concentration of any pollutant in the residuals exceeds the concentration for that pollutant, as stipulated in the following on a dry weight basis:

Pollutant

Monthly Average Concentration

(milligrams per kilogram)

(d) 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 on a dry weight basis:

Distance from Surface Disposal Unit Boundary to Closest Property Line (meters)
