Current through Register Vol. 39, No. 6, September 16, 2024
(a)
Analytical procedures for soil samples required under this Section shall be
methods accepted by the US EPA as suitable for determining the presence and
concentration of petroleum hydrocarbons for the type of petroleum
released.
(b) Soil samples
collected, including the most contaminated sample, shall be analyzed as follows
in order to determine the risks of the constituents of contamination:
(1) soil samples collected from a discharge
or release of low boiling point fuels, including gasoline, aviation gasoline,
and gasohol, shall be analyzed for volatile organic compounds and additives,
including isopropyl ether and methyl tertiary butyl ether, using EPA Method
8260;
(2) soil samples collected
from a discharge or release of high boiling point fuels, including kerosene,
diesel, varsol, mineral spirits, naphtha, jet fuels, and fuel oil no. 2, shall
be analyzed for volatile organic compounds using EPA Method 8260 and
semivolatile organic compounds using EPA Method 8270;
(3) soil samples collected from a discharge
or release of heavy fuels shall be analyzed for semivolatile organic compounds
using EPA Method 8270;
(4) soil
samples collected from a discharge or release of used and waste oil shall be
analyzed for volatile organic compounds using EPA Method 8260, semivolatile
organic compounds using EPA Method 8270, polychlorinated biphenyls using EPA
Method 8080, and chromium and lead using procedures specified in Subparagraph
(6) of this Paragraph;
(5) soil
samples collected from a discharge or release subject to this Section shall be
analyzed for alkane and aromatic carbon fraction classes using methods approved
by the Director under
15A NCAC
02H .0805(a)(1);
(6) analytical methods specified in
Subparagraphs (1), (2), (3), and (4) of this Paragraph shall be performed as
specified in the following references or the most recent version of these
references: Test Methods for Evaluating Solid Wastes:Physical/Chemical Methods,
November 1990, U.S. Environmental Protection Agency publication number SW-846,
is incorporated by reference and may be purchased for a cost of three hundred
sixty seven dollars ($367.00) from the Superintendent of Documents, U.S.
Government Printing Office (GPO), Washington, DC 20402; or in accordance with
other methods or procedures approved by the Director under
15A NCAC
02H .0805(a)(1);
(7) other EPA-approved analytical methods may
be used if the methods include the same constituents as the analytical methods
specified in Subparagraphs (1), (2), (3), and (4) of this Paragraph and meet
the detection limits of the analytical methods specified in Subparagraphs (1),
(2), (3), and (4) of this Paragraph; and
(8) metals and acid extractable organic
compounds shall be eliminated from analyses of soil samples collected pursuant
to this Section if these compounds are not detected in soil samples collected
during the construction of the source area monitoring well required under Rule
.0405 of this Section.
