Universal Citation: 06 ME Code Rules ยง 096-405-6

Current through 2024-38, September 18, 2024

A. Applicability. All special wastes proposed for storage, processing, beneficial use, agronomic utilization, or disposal in Maine must be characterized in accordance with a Department-approved plan. Any other solid waste may also be required to be characterized in accordance with a Department-approved plan. Facilities licensed solely for the transfer, storage, and/or disposal of municipal solid waste (MSW), wood waste and/or construction or demolition debris (CDD) are exempt from the characterization requirements of this section.

Solid waste facilities licensed to accept solid wastes characterized by the generator are not required to further characterize the waste at the facility, provided the solid wastes are clearly manifested from the point of generation to the accepting facility.

B. General Program Requirements. The owner or operator of a new solid waste facility or activity required to characterize waste under these rules, or by a license or an enforcement agreement, must develop a solid waste characterization program and submit it to the Department for review and receive approval prior to handling of the wastes. This program must be designed to determine the chemical and physical characteristics of the wastes and to monitor these characteristics on an on-going basis. The owner or operator of an existing solid waste facility or activity which has previously characterized its wastes is required to meet only the ongoing characterization requirements of this section, unless an alternative program is approved by the Department or the owner or operator proposes to handle a new waste stream which requires initial and on-going characterization under this section. The program must include detailed information addressing the following:

(1) General requirements. The applicant must comply with the following requirements in developing and implementing a solid waste characterization program:
(a) For the initial characterization of a waste from a specific source, the owner or operator shall prepare and submit to the Department a detailed description of all known or potential physical and chemical characteristics of the solid waste to be accepted for handling. This must include information regarding the materials and specific process from which the waste is generated, and Material Safety Data Sheets for those chemicals that may be a major component of the waste. Information may be obtained from the facility generating the waste, analytical results from a similar facility, and/or from the chemical literature;

(b) The applicant shall also include a complete list of references for all sources of information used in this assessment;

(c) All wastes proposed to be handled under the provisions of these rules must be fully characterized unless exempted from characterization. Any statistical analysis performed must be done in accordance with the requirements of US EPA SW-846, Test Methods for Evaluating Solid Waste, Third Edition, Volume II, Chapter 9, 2013 ("US EPA SW-846"). Waste must not be accepted at a solid waste facility or for a solid waste activity if the TCLP - Regulatory Limits or allowable limits for additional contaminants as determined in the facility or activity license have been equaled or exceeded. This determination must be made either through TCLP testing or through calculation utilizing the methodology described in Appendix D of this chapter; and

(d) A reduction in characterization requirements may be requested based on the generator's certification of waste history, process knowledge, and waste volume. The Department may also require additional parameters based upon the raw material, the proposed activity, or the facility.

(2) Waste Characterization Sampling and Analytical Work Plan. A waste characterization sampling and analytical work plan must be developed for initial and ongoing characterization of solid wastes, including residuals, handled under a solid waste license. The plan must include, at a minimum, a detailed description of the contaminants of concern in the waste or residual, the sampling and analytical methods used to obtain samples and quantify contaminants, and the guidance or other references used to develop the plan. The plan must be prepared in accordance with the specific analytical requirements of section 6(C) or 6(D).

The sampling plan must include:

(i) Identification of parameters to be analyzed and selection rationale;

(ii) Sample collection methods including a description of sampling equipment and how representative samples will be obtained;

(iii) Sample point description;

(iv) Sample size, sample type (e.g., grab, composite), and sample frequency;

(v) Procedures for decontamination of sampling equipment prior to sampling and between the collection of successive samples;

(vi) Sample container, storage and preservation procedures;

(vii) Sample holding times;

(viii) Sample handling, packaging, and transportation protocols;

(ix) Sample documentation (labeling, chain-of-custody, log book);

(x) Analytical methods;

(xi) Estimated practical quantitative limits for each parameter to be quantified;

(xii) Sampling and analysis quality assurance/quality control procedures; and

(xiii)Data reduction, validation and reporting methods including methods of statistical interpretation of analytical results.

In order to assure adequate waste characterization, the plan must be developed in accordance with Department-approved State or Federal guidance documents.

The frequency of sampling must be adequate to represent the residual or site conditions. Frequencies may be enumerated below or in 06-096 CMR ch. 419. The groups of parameters that the generator may be required to analyze for depends upon the processes that generate the residual, inputs to that process and the intended use of the residual. Groups of parameters that the Department may require to be analyzed for by the generator or at sites where residuals are utilized include the following:

(1) Soil Nutrient Analysis
(a) Initial analysis. A complete soil nutrient analysis includes the following: pH; available phosphorus; available potassium; available calcium; available magnesium; cation exchange capacity (C.E.C.); percent C.E.C. saturation with potassium; percent C.E.C. saturation with calcium; percent C.E.C. saturation with magnesium; percent C.E.C. saturation with sodium; and percent organic matter. Available nitrogen may be required by the Department to be measured. It may be measured in the field using protocols such as the Pre-Sidedress Nitrogen Test.

(b) On-going analysis. A minimum of one composite topsoil sample per eight (8) acres of utilization area must be collected at the site prior to utilization each year that a residual will be land applied. Results of the analyses must be received and interpreted by the license holder prior to utilization. These results must be used as a factor in determining the amount of residual to be land applied.

(2) Initial Residual Analysis. The Department may require that generators test for the following parameters. The Department will determine testing requirements based on the proposed utilization program, an assessment of parameters likely to be in the residual, an evaluation of the chemical compounds known or suspected to be present in the waste stream from which the sludge or residuals originate, the processes used to generate the residual, the database of analytical results developed by the Department, and other factors as appropriate.

Initial analysis for target volatile organic compounds, target semi-volatile organic compounds, total PCBs, and dioxin are required for: sewage sludge generated by POTWs with an average daily flow greater than 2.5 millions of gallons/day; POTWs with pulp and paper, tannery, textile-related or other significant industrial wastewater inputs; POTWs required to enact an Industrial Pretreatment Program according to U.S. EPA regulations 40 CFR Part 403 [iv] as amended up to July 1, 2014; and sludge or residuals from pulp and paper mills, tanneries, textile mills, and ash generators.

Initial analysis for target semi-volatile organic compounds, total PCBs, and dioxin are required for ash generators:

All residuals other than sewage sludge must be analyzed for the following total inorganic target compounds: Aluminum, Antimony, Arsenic, Barium, Boron, Beryllium, Cadmium, Calcium, Chromium, Cobalt, Copper, Iron, Lead, Magnesium, Manganese, Mercury, Molybdenum, Nickel, Potassium, Selenium, Silver, Sodium, Thallium, Vanadium, Zinc, and Cyanide. These parameters must be analyzed for using methods in SW 846.

(e) Sewage Sludge Metals. Sewage sludge must be analyzed for the following total metals: Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium and Zinc.

(f) Pathogens. Following treatment by one or more of the pathogen reduction standards in 06-096 CMR ch. 419, Appendix B, residuals which may contain human pathogens may require compliance testing for one or more of the following indicator parameters: Salmonella sp., Fecal Coliform, enteric virus, or Helminth ova.

(g) Compost stability. Compost stability may be measured using one of the following methods:
(i) Aerated Pile: The compost moisture content is adjusted to between 40 and 60%. The compost is then aerated and, with the ambient air above 45º F., formed into a pile no smaller than six feet in diameter and four feet high. The temperature is measured two feet into the pile. The stability class is determined for the compost based on the highest temperature difference between the compost and ambient temperature over the course of five days;

(ii) Dewars Flask (Insulated Container). The compost moisture content is adjusted to between 40 and 60%. The compost is then aerated, and enclosed in an insulated vacuum flask connected to a continuous reading internal/external thermometer. The stability class is determined for the compost based on the highest temperature difference between the encapsulated compost and ambient temperature over the course of five days; or

(iii)Respiration. The amount of CO2 generated or O2 consumed by a compost at a constant temperature and moisture is measured.

Other methods for determining stability may be approved by the Department on a case by case basis.

(h) Salt Toxicity. Salt toxicity must be determined by measurement of electrical conductivity, plant toxicity testing, or other methods approved by the Department.

(i) Target volatile organic compounds. All residuals other than woodash from woodash generators burning only wood waste must be analyzed for the target volatile organic compounds listed in Appendix C of this chapter. These parameters must be analyzed for total concentrations using methods in SW 846.

(j) Target semi-volatile compounds. A complete analysis for target semi-volatile compounds includes the Acid/Base-neutral target compoundslisted in Appendix D of this chapter. These parameters must be analyzed for total concentrations using methods in SW 846.

(k) Total PCBs. A complete analysis for total PCBs, including, but not limited to, the arochlors listed in Appendix C of this chapter. Total PCBs must be analyzed for using methods in SW 846.

Sampling and analysis must be performed in accordance with EPA method 1613, EPA method 8290, or another Department-approved method.

(ii) toxic Equivalency Factors. The results of the residual analyses must be used to calculate total 2,3,7,8-TCDD equivalents using the Toxic Equivalency Factors (TEF) in Tables 405.1 and 405.2 , which indicate the relative toxicity of mixtures of dioxins, furans and dioxin-like compounds in relationship to the toxicity of 2,3,7,8-PCDD. To calculate the total 2,3,7,8-PCDD equivalents, multiply each detect by the corresponding TEF then add all results. Reported non-detects (ND) at the method detection limit will be considered equal to 0. The TEFs from Table 405.2 will be used to determine compliance with the dioxin standard in 06-096 CMR ch. 419. Both calculations must be reported to the Department.

(n) Non-hazardous determination. Initial characterization of any residual proposed for agronomic utilization must include a determination that the residual is non-hazardous. This determination must be made either through TCLP testing or through calculation utilizing the methodology described in Appendix C of this chapter.

(o) Other. The Department may require analysis for other parameters that, based on a description of the process generating the residual, may be in the residual in significant concentrations to adversely impact the utilization program.

(3) Follow-up Residual Analysis. Follow-up sampling and analysis. The frequency of follow-up sampling and analysis will be established by license condition, and determined based on the initial analytical results for the residual, the Department's data base of analytical results, the potential for these compounds to be present in the material, and other factors as appropriate.

Sewage sludge must be analyzed for total arsenic, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium and zinc at the frequency in Table 405.3 unless otherwise approved by the Department based on specific characteristics.
