Ariz. Admin. Code § 18-13-1307

Current through Register Vol. 30, No. 44, November 1, 2024

Section R18-13-1307 - Best Management Practices for Waste from Shredding Motor Vehicles

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.
