15A NCAC 02T .1105. 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 Ceiling Concentration
(milligrams per kilogram)
Arsenic 75
Cadmium 85
Copper 4,300
Lead 840
Mercury 57
Molybdenum 75
Nickel 420
Selenium 100
Zinc 7,500
(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):
Pollutant Cumulative Pollutant
Loading Rate
(kilograms per hectare)
Arsenic 41
Cadmium 39
Copper 1,500
Lead 300
Mercury 17
Nickel 420
Selenium 100
Zinc 2,800
(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 Monthly Average Concentration
(milligrams per kilogram)
Arsenic 41
Cadmium 39
Copper 1,500
Lead 300
Mercury 17
Nickel 420
Selenium 100
Zinc 2,800
(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 Ceiling Concentration
Boundary to Closest Property Line (milligrams per kilogram)
(meters)
Arsenic Chromium Nickel
0 to less than 25 30 200 210
25 to less than 50 34 220 240
50 to less than 75 39 260 270
75 to less than 100 46 300 320
100 to less than 125 53 360 390
125 and greater 62 450 420
