A. A generator of shredder residue shall follow sampling protocol as follows or submit to the Department for review and approval, at least two weeks prior to the sampling event, an alternative written sampling plan which is consistent with requirements set forth in "Test Methods for Evaluating Solid Waste," EPA SW-846, 3rd Edition, Volume II, Chapter Nine, Sampling Plan, Physical/Chemical Method, EPA, Office of Solid Waste and Emergency Response, Washington, D.C., September 1986, and updated November 1990, and no future editions or amendments, ("EPA Sampling Plan"), herein incorporated by reference and on file with the Department and the Office of the Secretary of State:
1. Sample collection shall be done in
accordance with one of the following:
a.
Sampling procedure 1, consisting of both of the following steps:
i. The generator shall collect samples from a
shredder residue sampling pile which shall consist of the average amount of
shredder residue from eight hours of operation of the shredder. The shredder
residue sampling pile shall be formed into a square shape for sampling
purposes. Refer to Exhibit 1.
ii.
One 2,000-gram sample shall be collected from each sample point as indicated in
Exhibit 1. Samples from sample points A-1, B-1, and C-1 shall be collected from
the top of the pile. Samples from sample points A-2, B-2, and C-2 shall be
collected from the base of the pile. A sample from sample point C-3 shall be
collected at the vertical midpoint at the center of the pile. The seven
2,000-gram samples shall be numbered consecutively. Three of the seven
2,000-gram samples shall then be chosen at random by selecting numbers from a
calculator programmed to generate random numbers. The samples shall be analyzed
for the constituents and at the frequencies listed in Table A of this
Section.
b. Sampling
procedure 2, consisting of both of the following steps:
i. The generator shall collect seven
2,000-gram samples during or immediately following the normal generation of
shredder residue. For each sample, shredder residue shall be collected for 8 to
12 minutes, during which a minimum of 500 pounds shall be generated. This
process shall be performed seven times to create seven 500-pound amounts. Each
500-pound amount shall be formed into a square shape for sampling purposes.
Refer to Exhibit 1.
ii. Twenty
100-gram samples shall be collected from throughout each of the seven 500-pound
piles generated. Upon completion of collection, all 20 samples from each of the
seven 500-pound piles shall be combined together into seven separate 2,000-gram
samples and numbered consecutively. Three of the seven 2,000-gram samples shall
then be chosen at random by selecting numbers from a calculator programmed to
generate random numbers. The samples shall be analyzed for the constituents and
at the frequencies listed in Table A of this Section.
2. Each 2,000 grams of shredder
residue collected shall include both large and small particles, in proportion
to shredder residue generated. The generator shall use a container which is
large enough to hold the entire amount of shredder residue collected from each
sample point.
3. The generator
shall comply with requirements for sample preservation, temperature, and
holding times, as set forth in the EPA Sampling Plan.
4. Each one of the three 2,000-gram samples
selected at random shall be divided into four equal 500-gram portions and a
200-gram subsample shall be taken from each of the four equal 500-gram
portions. Each subsample shall then be passed through a 9.5mm screen. All
particles which do not pass through the 9.5mm screen shall be hand cut until
small enough to pass through the screen. All four 200-gram subsamples shall
then be remixed together and redivided into four equal 200-gram portions. The
following amounts shall be taken for constituent sampling:
a. 10-15 grams per 200-gram subsample for a
total of 40-60 grams per 2,000-gram sample for Polychlorinated Biphenyls (PCB)
analysis as set forth in subsection (A)(10).
b. 25 grams per 200-gram subsample for a
total of 100 grams per sample for toxicity characteristic leaching procedure
extractions for contaminants as set forth in
40 CFR
261.24, Table 1 (incorporated by reference in
R18-8-261(A)
), as set forth in subsection (A)(7).
c. 1.25 grams per 200-gram subsample for a
total of 5 grams per 2,000-gram sample for extraction fluid
determination.
5. Each
constituent sample shall be put into a container. Container labeling and
chain-of-custody documentation shall be consistent with the requirements in the
EPA Sampling Plan.
6. The
constituent samples shall be analyzed by a laboratory licensed by the Arizona
Department of Health Services in accordance with A.R.S. §
36-495.
7. Of the three samples selected at random,
one sample amount required by subsection (A)(4)(b) shall be analyzed for the
extractable heavy metals arsenic, barium, cadmium, chromium, lead, mercury,
selenium, and silver, as set forth in
40 CFR
261.24, Table 1. The remaining two samples
shall each be analyzed for extractable cadmium and lead.
8. If the results of all three of the
analyses for any extractable heavy metal in subsection (A)(7) above are below
the Regulatory Level of the Maximum Concentration of Contaminants for the
Toxicity Characteristic as set forth in
40 CFR
261.24, Table 1, the simple arithmetic mean
of the extractable cadmium and lead and the single analysis for the remaining
six extractable heavy metals shall be used to determine if the sampled shredder
residue will be classified as hazardous waste.
9. If the analyses of any one of three
selected samples exceeds the regulatory level as set forth in
40 CFR
261.24, Table 1, an additional subsample from
the sample in question shall be subjected to confirmation analysis. If the
confirmation sample analysis totals are in excess of the regulatory level as
set forth in
40 CFR
261.24, Table 1, the remaining four of the
original seven samples shall be analyzed for those extractable heavy metals
which exceed the regulatory level as set forth in
40 CFR
261.24, Table 1. The simple arithmetic mean
of the results of all seven samples shall be used to determine if the sampled
shredder residue will be classified as hazardous waste.
10. The three samples selected at random
shall be analyzed for PCB concentration in the amounts required by subsection
(A)(4)(a). If the samples contain concentrations of PCB less than 50 mg/kg, the
simple arithmetic mean of the three samples shall be used for reporting to the
Director. If any one of the three samples contains concentrations of PCB
greater than 50 mg/kg, an additional subsample from the sample in question
shall be subjected to confirmation analysis. If the PCB concentration for that
sample exceeds 50 mg/kg, the remaining four of the original seven samples shall
be analyzed for PCB, in amounts required by subsection (A)(4)(a), and the
simple arithmetic mean of all the samples shall be used to determine if the
sampled shredder residue will be classified as hazardous waste.
B. Shredder residue determined to be hazardous waste shall be managed in accordance with A.R.S. § 49-921 et seq. and R18-8-260 et seq.
C. The generator shall do all of the following:
1. Secure the facility
to prevent unauthorized entry;
2.
Cover or otherwise manage the shredder residue pile to prevent wind
dispersal;
3. Place the shredder
residue pile on a surface with a permeability coefficient equal to or less than
1 x 10-7 cm/s;
4. Design, construct, operate, and maintain a
run-on control system capable of preventing flow onto the waste pile during
peak discharge from, at a minimum, a 25-year storm;
5. Design, construct, operate, and maintain a
run-off management system to collect and control at a minimum, the water volume
resulting from a 24-hour, 25-year storm;
6. Provide collection and holding facilities
for run-on and run-off control systems, which shall have a permeability
coefficient equal to or less than 1 x 10-7
cm/s;
7. Record the date
accumulation of shredder residue begins.
D. Shredder residue shall be treated, recycled, sorted, stored, or disposed at a Department-approved special waste facility approved in accordance with A.R.S. § 49-857. A facility which seeks to become a special waste facility shall submit a special waste management plan to the Department to ensure compliance with subsection (C) of this Section.
E. A generator shall not store shredder residue for longer than 90 days. A special waste facility shall not store shredder residue for longer than one year.
F. The owner or operator of a special waste facility shall pay, to the Department, the fees required by A.R.S. §§ 49-855(C)(2) and 49-863 as follows:
1. $1.49 per cubic yard of
uncompacted shredder residue; or
2.
$3.38 per cubic yard of compacted shredder residue received; or
3. $4.50 per ton; and
4. Not more than $45,000 per generator site
per year for shredder residue that is transported to a facility regulated by
the Department for treatment, storage or disposal.
G. Shredder residue which has been determined to be nonhazardous pursuant to this Section shall be transported in accordance with the requirements for transportation of garbage as set forth in R18-13-310.
