4. Identification of Hazardous Wastes

A. General

(1) This rule identifies those wastes which are subject to regulation as hazardous wastes under 38 M.R.S.A., §1301, et seq.

(2) Portions of this rule refer to federal regulations of the United States Environmental Protection Agency (EPA). Unless otherwise specified, the federal regulations referenced are those interim final or final regulations revised as of July 1, 1988, as they appeared in volume 40 of the Code of Federal Regulations (CFR). Where specifically indicated, the terms of a referenced federal regulation are hereby adopted as terms of this rule, except that in regulations incorporated thereby, "EPA" shall mean "the Maine Department of Environmental Protection (DEP)"; "Administrator", "Regional Administrator" and "Director" shall mean "the Maine Board of Environmental Protection or its designated representative"; and the phrase "treat, store, and/or dispose" shall mean "handle". In addition, where the terms of federal regulations hereby incorporated by reference differ from or are inconsistent with other terms of this Chapter or Chapters 850‑860, the more stringent of the requirements shall apply. Other changes to regulations incorporated hereby are as expressly made in this rule.

Waste. "Waste" means any useless, unwanted or discarded substance or material, whether or not such substance or material has any other or future use and includes any substance or material that is spilled, leaked, pumped, poured, emitted, disposed, emptied, or dumped onto the land or into the water or ambient air. This definition includes, without being limited to, materials which are used in a manner constituting disposal, burned for energy recovery, reclaimed or accumulated speculatively.

NOTE: It is intended that the terms "materials which are used in a manner constituting disposal, burned for energy recovery, reclaimed or accumulated speculatively" should include all materials covered by 40 C.F.R. Section 261.2(c)(1)-(4) and any amendments thereto.

(3) Definition of hazardous waste

(a) A waste is a hazardous waste if:

(i) It is not excluded from regulation as a hazardous waste under Section 4A(4) of this rule; and

(ii) It meets any of the following criteria:

a. It is listed in Section 4(C) and has not been excluded by EPA under 40 CFR 260.20 and 260.22 and excluded subsequently by the Maine Board of Environmental Protection;

b. It is a mixture of a non‑hazardous waste and one or more hazardous wastes listed in Section 4(C) and has not been excluded by EPA under 40 CFR 260.20 and 260.22 and excluded subsequently by the Maine Board of Environmental Protection;

c. It exhibits any of the characteristics of hazardous waste identified in Section 4 (B) of this rule.

(b) A waste which is not excluded from regulation under paragraph 4(A)(3)(a)(i) of this section becomes a hazardous waste when any of the following events occur:

(i) In the case of a waste listed in Section 4 (C), when the waste first meets the listing description set forth in Section 4(C).

(ii) In the case of a mixture of a non‑hazardous waste and one or more listed hazardous wastes, when a hazardous waste listed in Section 4(C) is first added to the non‑hazardous waste.

(iii) In the case of any other waste (including a waste mixture), when the waste exhibits any of the characteristics identified in Section 4(B) of this rule.

(i) A hazardous waste will remain a hazardous waste.

(ii) Any waste generated from the handling of a hazardous waste, including any sludge, spill residue, ash, emission control dust or leachate (but not including precipitation run‑off), is a hazardous waste.

(d) Any waste described in paragraph (c) above is not a hazardous waste if it meets the following criteria:

(i) In the case of any waste, it does not exhibit any of the characteristics of hazardous waste identified in Section 4 (B).

(ii) In the case of a waste which is a listed waste under Section 4(C), contains a waste listed under Section 4(C) or is derived from a waste listed in Section 4(C), it also has been excluded from paragraph (c) by EPA under 40 CFR 260.20 and 260.22 and excluded subsequently by the Maine Board of Environmental Protection.

(4) Exclusions

(a) Substances which are not hazardous wastes. The following materials are not hazardous wastes for the purpose of this rule:

(i) Domestic sewage; and

(ii) Any mixture of domestic sewage and other wastes that passes through a sewer system to a publicly‑owned treatment works (POTW) for treatment, provided the mixture is a discharge of a non segregable waste at the site of generation, the mixture is a discharge from a source whose hazardous constituents are subject to categorical, local limits, and prohibitions established in accordance with Section 307(b) of the Clean Water Act, and the source is in compliance with those limits by means other than dilution and the hazardous constituents are sampled and analyzed no less frequently than annually. "Domestic sewage" means untreated sanitary wastes that pass through a sewer system. The unknowing receipt of hazardous waste by a POTW does not cause the POTW to become a hazardous waste facility.

NOTE: Unless the discharge is non segregable and is subject to categorical and local limits, persons discharging hazardous waste to POTWs via a sewer system containing domestic sewage or other means are subject to the applicable abbreviated license provisions of Chapter 856, Section 11. Dischargers to POTWs and POTWs are responsible for complying with the applicable provisions of Chapter 856, Section 11. See also Section 12(D) of Chapter 851. A waste is considered non-segregable when it is inherently mixed with wastewater and is not segregated in containers, tanks, pipes and sumps. A segregable waste cannot be introduced to wastewaters unless an abbreviated license is held for the activity.

(iii) Industrial wastewater discharges that are point source discharges subject to regulation under Section 402 of the Clean Water Act, as amended, in so far as any hazardous waste present in the discharge is in fact regulated.

NOTE: This exclusion applies only to the actual point source discharge. It does not exclude industrial wastewaters while they are being handled before discharge, or sludges that are generated by industrial wastewater treatment. The exclusion is further limited by the provisions under Chapter 856 for the abbreviated licensing of a POTW for treatment of a hazardous waste.

(iv) Irrigation return flows.

(v) Source, special nuclear or by‑product material as defined by the Atomic Energy Act of l954, as amended, 42 U.S.C.. 20ll et seq.

(vi) Materials subjected to in‑situ mining techniques which are not removed from the ground as part of the extraction process.

(vii) Household waste, including household waste that has been collected, transported, stored, treated, disposed, recovered (e.g., refuse‑derived fuel) or reused. "Household waste" means any waste material (including garbage, trash and sanitary wastes in septic tanks) derived from households (including single and multiple residences, hotels and motels, bunkhouses, picnic grounds, and day-use recreation areas.)

(viii) Wastes resulting from agricultural activities which are returned to the soils as fertilizers. "Agricultural activities" means the growing of vegetables, fruit, seeds, nursery crops, poultry, livestock, field crops, cultivated or pasture hay and farm woodlot products, including Christmas trees.

(ix) Mining overburden returned to the mine site.

Note: Wastes from the extraction and beneficiation of metallic ores and minerals are regulated under Chapter 200 of the Department's rules, not Chapters 850‑857.

(x) Fly ash waste, bottom ash waste, slag waste, and flue emission control waste generated solely from the combustion of coal, other fossil fuels, or wood or generated primarily from the combustion of coal and/or other fossil fuels and/or wood, providing that the waste does not exhibit any of the characteristics of hazardous waste as defined in Section 4(B)(2), (3), (4), or (5) of this rule.

(xi) Drilling fluids, produced waters. and other wastes associated with the exploration, development, or production of crude oil, natural gas or geothermal energy.

(xii) A sample of waste or sample of water, soil, or air which is collected for the sole purpose of testing to determine its characteristics or composition provided it meets the requirements of 40 CFR 261.4(d)(1)(i)‑(vi) which are hereby adopted and incorporated by reference, and the sample collector shipping samples to a laboratory and a laboratory returning samples to a sample collector comply with 40 CFR 261.4(d)(2) which is hereby adopted and incorporated by reference. This exemption does not apply if the laboratory determines the waste is hazardous but the laboratory is no longer meeting the requirements of this provision.

(xiii) Commercial chemical product that is unused and which is reinserted into the onsite manufacturing process without any alteration, or that is unused and unexpired and is shipped to the original manufacturer or distributor with their approval for use.

(xiv) Waste from the leather tanning and finishing industry including chrome (blue) trimmings, chrome (blue) shavings, and buffing dust; and scrap tanned leather from the leather tanning industry, the shoe manufacturing industry, and other leather product manufacturing industries, provided the generator can demonstrate the waste meets the exemption criteria of 40 CFR 261.4(b)(6)(i) which is hereby adopted and incorporated by reference, the waste is managed in a non oxidizing environment, and if disposed in Maine, is managed in a secure landfill.

NOTE: Due to the potential conversion of trivalent chromium to hexavalent chromium in certain situations, the increased leachability of certain types of chrome waste, and the current management of the waste in oxidizing environments, the Department's Hazardous Waste program continues to have concerns with the disposition of this waste stream. These wastes will be managed in secure landfills as special wastes under 06-096 CMR 400-406, 408 & 409 (May 24, 1989) the Department's Solid Waste Management Regulations.

(xv) Pulping liquors (i.e: black liquor) that are reclaimed in a pulping liquor recovery furnace and then reused in the pulping process, provided the storage of such liquor, if any, prior to reuse occurs in a fully enclosed tank and the liquors are not accumulated speculatively as defined in 40 CFR 261.1(c)

NOTE: For the purpose of this paragraph, pulping liquor that is spilled or otherwise released into the environment may qualify for this exemption only to the extent the liquor is recovered for subsequent reuse.

(xvi) Scrap metal which is recycled or intended to be recycled, provided it is not accumulated speculatively as defined in 40 CFR 261.1(c). "Scrap metal" means bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, wire) or metal pieces that may be combined together with bolts or soldering (e.g. radiators, scrap automobiles, railroad box cars), which when worn or superfluous can be recycled and which are not otherwise mixed with or contaminated with non metal hazardous wastes.

NOTE: It is the generator's responsibility to demonstrate to the Department that the scrap metal is being recycled.

(xvii) Materials in unopened containers which are unused, unexpired and which meet the product specifications, provided the materials are not used in a manner constituting disposal (unless the product is normally applied to the land) or burned for energy recovery (unless the product is a fuel).

(xviii) Unused, unexpired materials in an original container which meet the product specifications, provided the Chief Executive Officers or plant managers of the shipping and receiving facilities exchange letters acknowledging the exchange of material, the Department receives copies of these letters prior to shipment, and the materials are not used in a manner constituting disposal (unless the product is originally applied to the land) or burned for energy recovery (unless the product is a fuel.) The letter must contain the following information: (1) the type and quantity of material transferred; (2) the name, address and telephone number of the transferer and transferee; (3) the date of transfer; and (4) the proposed use of the materials by the transferee.

(xix) Isopropyl alcohol is excluded when shown to be recycled by being used or reused as an effective substitute for commercial products provided the isopropyl alcohol is not being reclaimed and the generator and recycling facility is in compliance with the following:

The generator and if located in Maine, the recycler, must maintain the following documentation at the facility of the generator and, if located in Maine, at the recycling facility, and be available for the Department’s inspection:

(1) A description of the isopropyl alcohol to be used or reused;

(2) Consistent with the requirements of 40 CFR 261.2(f) a demonstration that a known market or disposition exists for the isopropyl alcohol. This demonstration must include documentation such as a contract that a material is used to substitute for another product; a description of the process by which the isopropyl alcohol is beneficially used or reused; a representative analysis of the isopropyl alcohol including the hazardous constituents found in 40 CFR 261 Appendix VIII; and documentation that the use of the material does not introduce toxic constituents into the product, for which the material is used as a substitute, in concentrations that are higher than those found in analogous products consistent with 40 CFR 261.2(d)(3)(i)(B); and

(3) Consistent with the requirements of 40 CFR 261.2(f), a demonstration by the owners or operators of the receiving facilities that they are actually recycling the materials and documenting that they have the necessary equipment to do so.

Isopropyl alcohol is not exempt under this provision and is a hazardous waste, even if the recycling involves use or reuse, consistent with 40 CFR 261.2(c) and (e) if the isopropyl alcohol or associated materials are reclaimed, used in a manner constituting disposal, or used to produce products that are applied to land, or burned for energy recovery, used to produce a fuel, or contained in fuels, or if materials are accumulated speculatively as defined in 40 CFR 261.1(c)(8), or fed to a halogen acid furnace. A respondent in an action to enforce hazardous waste regulations who raises a claim that isopropyl alcohol is used or reused under this provision must demonstrate consistent with 40 CFR 261.2(f), that there is a known market or disposition for the material, and that they meet the terms of the exclusion.

(b) Samples

(i) Persons who generate or collect samples for the purpose of conducting a treatability study, as defined in 40 CFR 260.10 on July 19, 1988 (53 FR 27301) are not subject to the requirements of this Chapter, Chapter 851, or Chapter 853, nor are such samples included in the quantity determinations of Section 4(A)(5) of this Chapter, under the circumstances specific in paragraph (ii) where the conditions in paragraph (iii) are met.

(ii) The exclusion of paragraph (b)(i) shall apply when the sample is being collected and prepared for transportation by the generator or sample collector, the sample is being accumulated or stored by the generator or sample collector prior to transportation to a laboratory or testing facility, or the sample is being transported to the laboratory or testing facility for the purpose of conducting a treatability study.

(iii) The exclusion of paragraph (b)(i) shall apply when the conditions of 40 CFR 261.4(e)(2)(i)‑(vi) as revised on July 19, 1988 (53 FR 27301) are met, provided however, that the generator shall provide the information required in 40 CFR 261.4(e)(2)(vi) in its annual report, and prior approval has been obtained from the Department. The provisions of 40 CFR 261.4(e)(2)(i)‑(vi) as revised on July 19, 1988 are hereby adopted and incorporated by reference, except that the term "biennial" in 40 CFR 261.4(e)(2)(vi) shall mean "annual".

(i) For purposes of this subsection, “solvent-contaminated wipes” means woven or non-woven shop towels, rags, pads, or swabs made of wood pulp, fabric, cotton, polyester blends, or other material, that, after use or after cleaning up a spill, either:

(1) Contains one or more of the F001 through F005 solvents listed in section 4(C)(2) or the corresponding P- or U-listed solvents found in section (4)(C)(4);

(2) Contains one or more solvents listed in section 4(C) which exhibit a hazardous waste characteristic found in section (4)(B) when that characteristic results from a listed solvent; and/or,

(3) Contains one or more solvents that are not listed in section 4(C) which exhibit only the hazardous waste characteristic of ignitability found in section (4)(B)(2).

(i) Samples undergoing a treatability study and the laboratory or testing facility conducting such treatability study (to the extent the facility is not otherwise subject to the requirements of Chapters 850‑860) are not subject to the requirements of Chapters 850‑860 provided the conditions in paragraph (c)(ii) are met. A mobile treatment unit (MTU) may qualify as a testing facility, and where a group of MTUs are located at the same site, the limitations of paragraph (c)(ii) apply to the entire group of MTUs as if the group were one MTU.

(ii) The exclusion of paragraph (c)(i) shall apply when the conditions of 40 CFR 261.4(f)(1)‑(11), as revised on July 19, 1988 (53 FR 27302), are met (such provisions are hereby adopted and incorporated by reference, provided however, that references to "40 CFR 261.3" shall mean "this Chapter", "Parts 261 through 268 and Part 270 of this Chapter" shall mean "Chapters 850‑860" and "40 CFR 261.4(e)" shall mean "paragraph (b)(i)‑(iii) above") and prior approval has been obtained from the Department.

(5) Special requirements for hazardous waste generated by small quantity generators

(a) Except as otherwise provided in this section, if a person determines whether the waste he generates is hazardous under Chapter 851, Section 5 and generates, in a calendar month, a total of less than 100 kilograms (220.46 lbs.) of hazardous wastes, those wastes are not subject to regulation under 38 M.R.S.A., §1301, et seq. and related rules, provided the generator complies with paragraph (d) below.

NOTE: A small quantity generator is required to properly package for shipment, manifest, use a licensed hazardous waste transporter, and ship its hazardous waste to an authorized facility identified in Section 4(A)(5) (d)(v) of this chapter.

(b) If a person whose waste has been excluded from regulation under paragraph (a) above accumulates hazardous wastes in quantities greater than 600 kilograms or acutely hazardous wastes in quantities greater than set forth in paragraph (c) of this section, all of those accumulated wastes are subject to regulation under 38 M.R.S.A. §1301 et seq. and related rules (Chapters 850‑860 of the Department's rules).

(c) If a person generates in a calendar month or accumulates at any time any of the following acutely hazardous wastes in quantities greater than set forth below, those wastes are subject to regulation under 38 M.R.S.A., §1301 et seq. and related rules. (Chapters 850‑857 of the Department's Rules).

(i) A total of one kilogram of commercial chemical products and manufacturing chemical intermediates having the generic names listed in Section 4 C(4)(e) of this Chapter and off‑specification commercial chemical products and manufacturing chemical intermediates which, if they met specifications, would have the generic names listed in Section 4 (C)(4)(e) of this Chapter.

(ii) A total of one kilogram of the following hazardous wastes listed in Section 4(C)(2)(a) of this rule: Industry and EPA hazardous waste Nos. F020, F021, F022, F023, F026, F027, and F028.

(iii) Any containers identified in Section 4(C)(4)(c) of this Chapter that are larger than 20 liters in capacity;

(iv) Ten (10) kilograms of inner liners from containers identified in Section 4 (C)(4)(c) of this Chapter;

(v) A total of 100 kilograms of any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any commercial chemical products or manufacturing chemical intermediates having the generic names listed in Section 4(C)(4)(e) of this Chapter or any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any off‑specification commercial chemical products or manufacturing chemical intermediates which, if they met specifications, would have the generic names listed in Section 4(C)(4)(e) of this Chapter;

NOTE: Any person who exceeds the quantity requirements outlined in Sections 4(A)(5)(b) and 4(A)(5)(c) of this rule is subject to full regulation (i.e., regulation applicable to generators of greater than 100 kilograms per month of hazardous waste), including the requirements of Chapter 851, Section 8(B) that relate to accumulation times for hazardous waste. The time period in Section 8(B) of Chapter 851 begins when the accumulated wastes exceed the applicable exclusion limit.

(d) In order for hazardous waste to be excluded from regulation under this section, the generator must:

(i) Determine whether the waste generated is hazardous in accordance with Section 5 of Chapter 851;

(ii) Store the waste in a container no greater than 55 gallons in size, label and package the hazardous waste in accordance with Section 8(A) and 8(B)(3) of Chapter 851, and label the container with the date the container becomes full;

(iii) Properly manifest the hazardous waste in accordance with Chapter 857;

(iv) Utilize a licensed transporter in accordance with Section 7 of Chapter 851;

(v) Transport, or offer for transport, such waste only to a waste facility for hazardous waste which is authorized to handle the waste under a state program, and if applicable, under the federal hazardous waste regulatory program; and

(vi) Ship off site such waste within 180 days of the date the drum becomes full; and

(vii) If more than 55 gallons (approximately 200 kg) of a non-acutely hazardous waste is stored onsite, the generator must in addition:

a. Manage the waste in accordance with Sections 8(B)(2), 11, 13(B)(1),(2), 13(C)(1), (3), (4) and 13(D)(1), and (2) of Chapter 851; and

b. Have a generator identification number assigned to the generator by the United States Environmental Protection Agency if the generator will be operating under the provisions of 4(A)(5)(d)(vii) of this Chapter.

NOTE: To be eligible for the reduced requirements of this section, a small quantity generator must store its waste in containers.

(e) Hazardous waste subject to the reduced requirements of paragraph (d) that is mixed with non‑hazardous waste remains subject to these reduced requirements as long as the resultant mixture does not exceed the quantity limitations identified in this section. If any person mixes a solid waste with a hazardous waste that exceeds a quantity exclusion level of this section, the mixture is subject to full regulation. Mixture of a characteristic hazardous waste with a non hazardous waste such that the mixture no longer exhibits a characteristic constitutes treatment which requires a license pursuant to Chapters 854 and 856.

(6) Special requirements for hazardous waste which is beneficially used or reused

(a) Activities that may be eligible for reduced licensing requirements because those activities involve hazardous waste which is beneficially used or reused are specified under Section 11 of Chapter 856, License by Rule.

(b) Activities that involve recycling and reclamation of hazardous waste are considered forms of treatment and, as such, are subject to the requirements of Chapter 854 and 856 with respect to treatment of hazardous waste.

(7) Residues of hazardous waste in empty containers. Any residue remaining in a container or an inner liner removed from a container that has held any hazardous waste other than hazardous waste identified as acute hazardous waste in Section 4(C)(2), 4(C)(3) or 4(C)(4)(e) is a hazardous waste unless the container is empty as defined below:

(a) All wastes have been removed that can be removed using the practices commonly employed to remove materials from that type container and

(b) No more than one inch of residue containing no free liquids remains on the bottom of the container or inner liner or

NOTE: Removing free liquids from a container may include: draining the emptied container for at least thirty (30) seconds after the steady flow of hazardous waste has ceased and individual droplets are clearly evident and then performing that procedure two more times.

(d) If the container has held a hazardous waste that is a compressed gas, the pressure in the container is at atmospheric.

Any residue remaining in a container or an inner liner removed from a container that has held an acute hazardous waste is empty if the container or inner liner has been triple rinsed using a solvent capable of removing the waste or, in the case of a container, the inner liner that prevented contact of the commercial chemical product or manufacturing chemical intermediate with the container, has been removed.

(8) The use of material which is contaminated or mixed with dioxin or any other hazardous waste identified in Chapter 850, for dust suppression or road treatment is prohibited.

(9) No fuel which contains any hazardous waste may be burned in any cement kiln unless licensed under Chapter 856.

(10) Persons who generate, transport, or collect non‑leaking spent lead acid batteries, or who store non‑leaking spent batteries but do not reclaim or intend to reclaim them are not required to obtain a license for such a facility.

(11) Owners or operators of facilities that store spent lead acid batteries before reclaiming them are required to obtain a license for such storage under Chapter 856.

(12) Delistings: [RESERVED]

RESERVED SPACE

NOTE: The intentional breaking of universal wastes including Cathode Ray Tubes is a form of treatment, and is therefore prohibited at locations other than the recycling facility.

(ii) Sending a universal waste to any facility other than a central accumulation facility, a consolidation facility for universal waste, an approved recycling facility for universal wastes, or in the case of ballasts and the residues from mercury spill kits to an approved disposal or treatment facility.

NOTE: Generators that self-transport waste must comply with universal waste transporter requirements, as provided in Section 11 of Chapter 853.

NOTE: Chapters 854 and 856 apply to a universal waste recycling facility.

(c) Household hazardous waste, which meets the description of universal waste in Section 4A(13)(b) but which is exempt under Section 4A(4)(a)(vii), when combined or mixed with universal wastes is no longer exempt and must be managed in accordance with the requirements of Chapter 850, 851, 853, 856, 857, and 858.

(e) All generators of universal wastes must:

(i) Determine whether the waste generated is hazardous in accordance with Section 5 of Chapter 851 and , pursuant to 38 M.R.S.A. § 1663 determine that all mercury containing lamps are a universal waste; and

(ii) Determine whether the waste is a universal waste under section 13(b) above;

NOTE: If a hazardous waste is not eligible for regulation under the universal waste rules, then the full hazardous waste management rules apply.

(iii) Immediately contain and transfer all releases of waste and residues resulting from spills or leaks from broken or ruptured universal waste to a container that meets the requirements of the Maine Hazardous Waste Management Rules (Chapter 850 through 857), except that waste and residues from incidental breakage may still be managed as a universal waste;

(iv) Determine by testing, or handle as hazardous, clean up residues resulting from spills or leaks from events other than incidental breakage of lamps or CRTs in accordance with Maine Hazardous Waste Management Rules (Chapter 850 through 857) including generator accumulation time limit, storage and disposal standards, and count this waste toward the determination of hazardous waste generator status;

(14) Special requirements for certain batteries

Batteries that are described in 40 CFR 273.2 revised as of July 1, 2001 must be managed in accordance with 40 CFR 273 revised as of July 1, 2001, except that references to 40 CFR Parts 260 through 272 shall mean 850 through 857 of the Maine Hazardous Waste Management Rules and except that 40 CFR 273.8(a)(2) is not adopted, and instead, batteries handled by federally conditionally exempt small quantity generators are regulated as small quantity handlers pursuant to 40 CFR 273 Subpart B. In addition, instead of 40 CFR 273.2(c), a battery becomes a waste on the date that it becomes useless, unwanted, or intended for disposal, and spent lead acid batteries described in 40 CFR 273.2(a)(2) and 273.2(b)(1) are regulated under 850 through 858 instead of 40 CFR part 266, subpart G.

(4) Discarded commercial chemical products, off-specification species, container residues, and spill residues thereof. The following materials or items are hazardous wastes if and when they are discarded or intended to be discarded, when they are mixed with other material and applied to the land for dust supression or road treatment, when they are otherwise applied to the land in lieu of their original intended use or when they are contained in products that are applied to the land in lieu of their original intended use or when, in lieu of their original intended use, they are produced for use as (or as a component of) a fuel, distributed for use as a fuel, or burned as a fuel:

(a) Any commercial chemical product, or manufacturing chemical intermediate having the generic name listed in paragraphs (e) or (f) of this section.

(b) Any off‑specification commercial chemical product or manufacturing chemical intermediate which, if it met specifications, would have the generic name listed in paragraphs (e) or (f) of this section.

(c) Any residue remaining in a container or an inner liner removed from a container that has held any commercial chemical product or manufacturing chemical intermediate having the generic name listed in paragraph (e) of this section, unless the container is empty as defined in Section 4(A)(7) of this Chapter. Containers which have contained medicinal nitroglycerin are considered empty if they meet the provisions of Section 4(A)(7)(a) and (b).

(d) Any residue or contaminated soil, water or other debris resulting from the cleanup of a spill into or on any land or water of any commmercial chemical product or manufacturing chemical intermediate having the generic name listed in paragraph (e) or (f) of this section, or any residue or contaminated soil, water or other debris resulting from the cleanup of a spill, into or on any land or water, of any off‑specification chemical product and manufacturing chemical intermediate which, if it met specifications, would have the generic name listed in paragraph (e) or (f) of this section.

NOTE: The phrase "commercial chemical product or manufacturing chemical intermediate having the generic name listed in . . ." refers to a chemical substance manufactured or formulated for commercial or manufacturing use which consists of: (1) the commercially pure grade of the chemical, (2) any technical grades of the chemical that are produced or marketed, (3) any formulations in which the P or U listed chemical is the sole active ingredient regardless of the percent composition, or (4) effective Janaury 1, 1995, any formulations in which the P listed chemical is an active ingredient of 10% or more. It does not refer to a material, such as a manufacturing process waste, that contains any of the substances listed in paragraphs (e) or (f). Where a manufacturing process waste is deemed to be a hazardous waste because it contains a substance listed in paragraphs (e) or (f), such waste will be listed in either Section 4(C)(2) or Section 4(C)(3) or will be identified as a hazardous waste by the characteristics set forth in Section 4(B) of this rule.

(e) The commercial chemical products, manufacturing chemical intermediates or off‑specification commercial chemical products or manufacturing chemical intermediates referred to in paragraphs (a) through (d) of this section, are identified as acute hazardous wastes (H) and are subject to the small quantity exclusion defined in Section 4(A)(5)(c).

NOTE: For the convenience of the regulated community the primary hazardous properties of these materials have been indicated by the letters T* (Human Toxicity), and R (Reactivity). Absence of a letter indicates that the compound is listed on the basis of animal toxicity data.

NOTE: all amendments to reference F027: 50 FR 2000, Jan. 14, 1985, Final Rule.

D. Criteria for designation of hazardous waste as universal waste.

In determining whether a waste may be designated a universal waste, the Maine Board of Environmental Protection must determine that:

(1) the waste or category of the waste meets the definition of a hazardous waste;

(2) the waste or category of the waste is a manufactured product that is not easily contaminated with other substances:

(3) the waste or a category of the waste is not exclusive to a specific industry or group of industries, is commonly generated by a wide variety of types of establishments (including, for example, households, retail and commercial businesses, office complexes, small businesses, government organizations, as well as large industrial facilities);

(4) the waste or category of waste is generated by a large number of generators (e.g., more than 1,000 nationally) and is frequently generated in relatively small quantities by each generator;

(5) systems to be used for collecting the waste or category of waste including packaging, marking, labeling, storage, and tracking would ensure close stewardship of the waste;

(6) the risk posed by the waste or category of waste during accumulation and transport is relatively low compared to other hazardous wastes, and specific management standards developed for the waste type would be protective of human health and the environment during accumulation and transport;

(7) regulation of the waste or category of waste under the designation of universal waste will increase the likelihood that the waste will be diverted from non hazardous waste management systems to recycling, or where appropriate treatment or disposal, in compliance with the full hazardous waste regulations;

(8) regulation of the waste or category of waste under the designation of universal waste will improve implementation of and compliance with the hazardous waste regulatory program; and

(9) such other factors as may be appropriate.

APPENDIX I:

REPRESENTATIVE SAMPLING METHODS

(Appendix I of this rule corresponds to Appendix I of 40 CFR 261)

The methods and equipment used for sampling waste materials will vary with the form and consistency of the waste materials to be sampled. Samples collected using the sampling protocols listed below, for sampling waste with properties similar to the indicated materials, will be considered by the Agency [EPA] to be representative of the waste.

Extremely viscous liquid‑‑ASTM Standard D140‑70 Crushed or powdered material‑‑ASTM Standard D346‑75 Soil or rock‑like material‑‑ASTM Standard D420‑69 Soil‑like material‑‑ASTM Standard D1452‑65

Fly Ash‑like material‑‑ASTM Standard D2234‑76 [ASTM Standards are available from ASTM, 1916 Race St., Philadelphia, PA 19103]

Liquid waste in pits, ponds, lagoons, and similar reservoirs.‑‑"Pond Sampler" described in "Test Methods for the Evaluation of Solid Waste, Physical/Chemical Methods."1

This manual also contains additional information on application of these protocols.

1These methods are also described in "Samplers and Sampling Procedures for Hazardous Waste Streams," EPA 600/2‑80‑018, January, 1980.

APPENDIX II:

METHOD 1311

TOXICITY CHARACTERISTIC LEACHING PROCEDURE (TCLP)

See 40 CFR 261. Appendix II (July 1, 2003 Version) for specific procedure.

APPENDIX III: CHEMICAL ANALYSIS TEST METHODS

(Appendix III of this rule corresponds to Appendix III of 40 CFR 261.)

Tables 1, 2 and 3 specify the appropriate analytical procedures, described in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods"1, which shall be used in determining whether a sample contains a given Appendix VII or VIII toxic constituent. Table 1 identifies each Appendix VII or VIII organic constituent along with the approved measurement method. Table 2 identifies the corresponding methods for the inorganic species. Table 3 summarizes the contents of SW‑846 and supplies specific section and method numbers for sampling and analysis methods.

Prior to final sampling and analysis method selection, the analyst should consult the specific section or method described in SW‑846 for additional guidance on which of the approved methods should be employed for a specific sample analysis situation.

APPENDIX X:

METHOD OF ANALYSIS FOR CHLORINATED

DIBENZO‑p‑DIOXINS AND DIBENZOFURANSl,2,3,4

This method is the same as that listed in Appendix X to 40 CFR Part 261.

Method 8280

1. Scope and Application.

1.1 This method measures the concentration of chlorinated dibenzo‑p‑dioxins and chlorinated dibenzofurans in chemical wastes including still bottoms, filter aids, sludges, spent carbon, and reactor residues, and in soils.

1.2 The sensitivity of this method is dependent upon the level of interferences.

1.3 This method is recommended for use only by analysts experienced with residue analysis and skilled in mass spectral analytical techniques.

1.4 Because of the extreme toxicity of these compounds, the analyst must take necessary precautions to prevent exposure to himself, or to others, of materials known or believed to contain CDDs or CDFs.

1This method is appropriate for the analysis of tetra‑, penta‑, and hexa‑ chlorinated dibenzo‑p‑dioxins and ‑di‑ benzofurans.

2Analytical protocol for determination of TCDDs in phenolic chemical wastes and soil samples obtained from the proximity of chemical dumps. T.O. Tiernan and M. Taylor, Berhm Laboratory, Wright State University, Dayton, Ohio 45435.

3Analytical protocol for determination of chlorinated dibenzo‑p- dioxins and chlorinated dibenzofurans in river water. T.O. Tiernan and M. Taylor, Berhm Laboratory, Wright State University, Dayton, Ohio 45435.

4In general, the techniques that should be used to handle these materials are those which are followed for radioactive or infectious laboratory materials. Assistance in evaluating laboratory practices may be obtained from industrial hygienists and persons specializing in safe laboratory practices. Typical infectious waste incinerators are probably not satisfactory devices for disposal of materials highly contaminated with CDDs and CDFs. Safety instructions are outlined in EPA Test Method 613(4.0)

Tucker, et al., eds., Plenum Publishing Corp., 1983. 2) Safety procedures outlined in EPA Method 613, Federal Register Volume 44, No. 233, December 3, 1979.

2. Summary of the Method

2.1 This method is an analytical extraction cleanup procedure, and capillary column gas chromatograph‑low resolution mass spectrometry method, using capillary column GC/MS conditions and internal standard techniques, which allow for the measurement of PCDDs and PCDFs in the extract.

2.2 If interferences are encountered, the method provides selected general purpose cleanup procedures to aid the analyst in their elimination.

3. Interferences

3.1 Solvents, reagents, glassware, and other sample processing hardware may yield discrete artifacts and/or elevated baselines causing misinterpretation of gas chromatograms. All of these materials must be demonstrated to be free from interferences under the conditions of the analysis by running method blanks. Specific selection of reagents and purification of solvents by distillation in all‑glass systems may be required.

3.2 Interferences co‑extracted from the samples will vary considerably from source to source, depending upon the diversity of the industry being sampled. PCDD is often associated with other interfering chlorinated compounds such as PCB's which may be at concentrations several orders of magnitude higher than that of PCDD. While general cleanup techniques are provided as part of this method, unique samples may require additional cleanup approaches to achieve the sensitivity stated in Table 1.

3.3 The other isomers of tetrachlorodibenzo‑p‑dioxin may interfere with the measurement of 2,3,7,8‑TCDD. Capillary column gas chromatography is required to resolve those isomers that yield virtually identical mass fragmentation patterns.

4. Apparatus and Material

4.1 Sampling equipment for discrete or composite sampling.

4.1.1 Grab sample bottle ‑ amber glass, l liter or l quart volume. French or Boston Round design is recommended. The container must be washed and solvent rinsed before use to minimize interferences.

4.1.2 Bottle caps ‑ threaded to screw on to the sample bottles. Caps must be lined with Teflon. Solvent washed foil, used with the shiny side towards the sample, may be substituted for the Teflon if sample is not corrosive.

4.1.3 Compositing equipment ‑ automatic or manual composing system. No tygon or rubber tubing may be used, and the system must incorporate glass sample containers for the collection of a minimum of 250 ml. Sample containers must be kept refrigerated after sampling.

4.2 Water bath ‑ heated, with concentric ring cover, capable of temperature control (+2º C). The bath should be used in a hood.

4.3 Gas chromatograph/mass spectrometer data system.

4.3.1 Gas chromatograph: An analytical system with a temperature‑programmable gas chromatograph and all required accessories including syringes, analytical columns, and gases.

4.3.2 Column: SP‑2250 coated on a 30 m long X 0.25 mm I.D. glass column (Supelco No. 2‑3714 or equivalent). Glass capillary column conditions: Helium carrier gas at 30 cm/sec linear velocity run splitless. Column temperature is 210o C.

4.3.3 Mass spectrometer: Capable of scanning from 35 to 450 amu every l sec or less, utilizing 70 volts (nominal) electron energy in the electron impact ionization mode and producing a mass spectrum which meets all the criteria in Table 2 when 40 ng of decafluorotriphenyl‑ phosphine (DFTPP) is injected through the GC inlet. The system must also be capable of selected ion monitoring (SIM) for at least 4 ions simultaneously, with a cycle time of 1 sec or less. Minimum integration time for SIM is l00 ms. Selected ion monitoring is verified by injecting .015 ng of TCDD Cl37 to give a minimum signal to noise ratio of 5 to l at mass 328.

4.3.4 GC/MS interface: Any GC‑to‑MS interface that gives acceptable calibration points at 50 ng per injection for each compound of interest and achieves acceptable tuning performance criteria (see Section 6.1‑6.3) may be used. GC‑to‑MS interfaces constructed of all glass or glass‑lined materials are recommended. Glass can be deactivated by silanizing with dichlorodi- methylsilane. The interface must be capable of interest from GC to the MS.

4.3.5 Data system: A computer system must be interfaced to the mass spectrometer. The system must allow the continuous acquisition and storage on machine‑readable media of all mass spectra obtained throughout the duration of the chromato‑graphic program. The computer must have software that can search any GC/MS data file for ions of a specific mass and that can plot such ion abundance versus time or scan number. This type of plot is defined as an Extracted Ion Current Profile (EICP). Software must also be able to integrate the abundance, in any EICP, between specified time or scan number limits.

4.4 Pipettes‑Disposable, Pasteur, 150 mm long X 5 ID (Fisher Scientific Co., No. 13‑678‑6A or equivalent).

4.5 Flint glass bottle (Teflon‑lined screw cap).

4.6 Reacti‑vial (silanized) (Pierce Chemical Co.).

5. Reagents

5.1 Potassium hydroxide‑(ACS), 2% in distilled water.

5.2 Sulfuric acid‑(ACS), concentrated.

5.3 Methylene chloride, hexane, benzene, petroleum ether, methanol, tetradecane‑pesticide quality or equivalent

5.4 Prepare stock standard solutions of TCDD and 37Cl‑TCDD (molecular weight 328) in a glove box. The stock solutions are stored in a glovebox, and checked frequently for signs of degradation or evaporation, especially just prior to the preparation of working standards.

5.5 Alumina‑basic, Woelm: 80/200 mesh. Before use activate overnight at 600oC, cool to room temperature in a dessicator.

5.6 Prepurified nitrogen gas.

6.0 Calibration

6.1 Before using any cleanup procedure, the analyst must process a series of calibration standards through the procedure to validate elution patterns and the absence of interferences from reagents.

6.2 Prepare GC/MS calibration standards for the internal standard technique that will allow for measurement of relative response factors of at least three CDD/37CDD ratios. Thus, for TCDDs at least three TCDD/37cl‑TCDD and TCDF/37Cl‑TCDF must be determined.5

5 37Cl‑labelled 2,3,7,8‑TCDD and 2,3,7,8‑ TCDF are available from K.O.R. Isotopes and Cambridge Isotopes, Inc., Cambridge, MA. Proper standardization requires the use of a specific labelled isomer for each congener to be determined. However, the only labelled isomers readily available are 37Cl‑2,3,7,8‑TCDD and Cl‑2,3,7,8‑TCDF. This method therefore uses these isomers as surrogates for the CDDs and CDFs. When other labelled CDDs and CDFs are available, their use will be required.

The 37Cl‑TCDD/F concentration in the standard should be fixed and selected to yield a reproducible response at the most sensitive setting of the mass spectrometer. Response factors for PCDD and HxCDD may be determined by measuring the response of the tetrachloro‑ labelled compounds relative to that of the unlabelled 1,2,3,4‑ or 2,3,7,8‑TCDD, 1,2,3,4,7‑ PCDD or 1,2,3,4,7,8‑HxCDD, which are commercially available.6

6.3 Assemble the necessary GC/MS apparatus and establish operating parameters equivalent to those indicated in Section 11.1 of this method. Calibrate the GC/MS system according to Eichelbarger, et al. (1975) by the use of decafluorotriphenyl phosphine (DFTPP). By injecting calibration standards, establish the response factors for CDDs vs. 37Cl‑TCDD, and for CDFs vs. 37Cl‑TCDF. The detection limit provided in Table 1 should be verified by injecting .015 ng of 37Cl‑TCDD which should give a minimum signal to noise ratio of 5 to 1 at mass 328.

7. Quality Control

7.1 Before processing any samples, the analyst should demonstrate through the analysis of a distilled water method blank, that all glassware and reagents are interference‑free. Each time a set of samples is extracted, or there is a change in reagents, a method blank should be processed as a safeguard against laboratory contamination.

7.2 Standard quality assurance practices must be used with this method. Field replicates must be collected to measure the precision ofthe sampling technique. Laboratory replicates must be analyzed to establish the precision of the analysis. Fortified samples must be analyzed to establish the accuracy of the analysis.

8. Sample Collection, Preservation, and Handling

8.1 Grab and composite samples must be collected in glass containers. Conventional sampling practices should be followed, except that the bottle must not be prewashed with sample before collection. Composite samples should be collected in glass containers in accordance with the requirements of the RCRA program. Sampling equipment must be free of tygon and other potential sources of contamination.

8.2 The samples must be iced or refrigerated from the time of collection until extraction. Chemical preservatives should not be used in the field unless more than 24 hours will elapse before delivery to the laboratory. If an aqueous sample is taken and the sample will not be extracted within 48 hours of collection, the sample should be adjusted to a pH range of 6.0‑8.0 with sodium hydroxide or sulfuric acid.

8.3 All samples must be extracted within 7 days and completely analyzed within 30 days of collection.

6This procedure is adopted because standards are not available for most of the CDDs and CDFs and assumes that all the cogeners will show the same response as the unlabelled cogener used as a standard. Although this assumption may not be true in all cases, the error will be small.

9. Extraction and Cleanup Procedures

9.1 Use an aliquot of 1‑10 g sample of the chemical waste or soil to be analyzed. Soils should be dried using a stream or prepurified nitrogen and pulverized in a ball‑mill or similar device. Perform this operation in a clear are a with proper hood space. Transfer the sample to a tared 125 ml flint glass bottle (Teflon‑lined screw cap) and determine the weight of the sample. Add an appropriate quantity of 37Cl‑ labelled 2,3,7,8‑TCDD (adjust the quantity according to the required minimum detectable concentration), which is employed as an internal standard.

9.2 Extraction

9.2.1 Extract chemical waste samples by adding 10 ml methanol, 40 ml petroleum ether, 50 ml doubly distilled water, and then shaking the mixture for 2 minutes. Tars should be completely dissolved in any of the recommended neat solvents. Activated carbon samples must be extracted with benzene using method 3540 in SW‑ 846 (Test Methods for Evaluating Solid Waste‑ Physical/Chemical Methods, available from G.P.O. Stock #055‑022‑81001‑2). Quantitatively transfer the organic extract or dissolved sample toa clean 250 ml flint doubly distilled water and shake for 2 minutes. Discard the aqueous layer and proceed with Step 9.3.

9.2.2 Extract soil samples by adding 40 ml of petroleum ether to the sample, and then shaking for 20 minutes. Quantitatively transfer the organic extract to a clean 250 ml flint glass bottle (Teflon‑lined screw cap), add 50 ml doubly distilled water and shake for 20 minutes. Discard the aqueous layer and proceed with step 9.3.

9.3 Wash the organic layer with 50 ml of 20% aquoid potassium hydroxide by shaking for 10 minutes and then remove and discard the aqueous layer.

9.4 Wash the organic layer with 50 ml of doubly distilled water by shaking for 2 minutes, and discard the aqueous layer.

9.5 Cautiously add 50 ml concentrated sulfuric acid and shake for 10 minutes. Allow the mixture to stand until layers separate (approximately 10 minutes) and remove and discard the acid layer. Repeat acid washing until no color is visible in the acid layer.

9.6 Add 50 ml doubly distilled water to the organic extract and shake for 2 minutes. Remove and discard the aqueous layer and dry the organic layer by adding 10g of anhydrous sodium sulfate.

9.7 Concentrate the extract to incipient dryness by heating in a 55º C water bath and simultaneously flowing a stream of prepurified nitrogen over the extract. Quantitively transfer the residue to an alumina microcolumn fabricated as follows:

9.7.1 Cut off the top section of a 10 ml disposable Pyrex pipette at the 4.0 ml mark and insert a plug of silanized glass wool into the tip of the lower portion of the pipette.

9.7.2 Add 2.8g of Woelm basic alumina (previously activiated at 600º C overnight and then cooled to room temperature in a dessicator just prior to use).

9.7.3 Transfer sample extract with a small volume of methylene chloride.

9.8 Elute the microcolumn with 10 ml of 3% methylene chloride‑in‑hexane and discard these effluents. Elute the column with 15 ml of 50% methylene chloride‑in‑hexane and concentrate this effluent (55º C water bath, stream of prepurified nitrogen) to about 0.3‑0.5 ml.

9.9 Quantitatively transfer the residue (using methylene chloride to rinse the container) to a silanized Reacti‑Vial (Pierce Chemical Co.). Evaporate, using a stream of prepurified nitrogen, almost to dryness, rinse the walls of the vessel with approximately 0.5 ml methylene chloride, evaporate just to dryness, and tightly cap the vial. Store the vial at 5º C until analysis, at which time the sample is reconstituted by the addition of tridecane.

9.10 Approximately 1 hour before the GC/MA (HRGC‑LRMS) analysis, dilute the residue in the micro‑reaction vessel with an appropriate quantity of tridecane. Gently swirl the tridecane on the lower portion of the vessel to ensure dissolution of the CDDs and CDFs. Analyze a sample by GC/EC to provide insight into the complexity of the problem, and to determine the manner in which the mass spectrometer should be used. Inject an appropriate aliquot of the sample into the GC/MS instrument, using a syringe.

9.11 If, upon preliminary GC/MS analysis, the sample appears to contain interfering substances which obscure the analyses for CDDs and CFDs, high performance liquid chromatograph (HPLC) cleanup of the extract is accomplished, prior to further GC‑MS analysis.

10. HPLC Cleanup Procedure7

10.1 Place approximately 2 ml of hexane in a 50 ml flint glass sample bottle fitted with a Teflon‑lined cap.

10.2 At the appropriate retention time, position sample bottle to collect the required fraction.

10.3 Add 2 ml of 5% (w/v) sodium carbonate to the sample fraction collected and shake for one minute.

10.4 Quantitatively remove the hexane layer (top layer) and transfer to a micro‑reaction vessel.

10.5 Concentrate the fraction to dryness and retain for further analysis.

11. GC/MS Analysis

11.1 The following column conditions are recommended: Glass capillary column conditions: SP‑2250 coated on a 30 m long x 0.25 mm I.D. glass column (Supelco No. 2‑3714, or equivalent) with helium carrier gas at 30 cm/sec linear velocity, run splitless. Column temperature is 210oC. Under these conditions the retention time for TCDDs is about 9.5 minutes. Calibrate the system daily with a minimum three injections of standard mixtures.

11.2 Calculate response factors for standards relative to 37Cl‑TCDD/F (see Section 12).

11.3 Analyze samples with selected ion monitoring of at least two ions form Table 3. Proof of the presence of CDD or CDF exists if the following conditions are met:

11.3.1 The retention time of the peak in the sample must match that in the standard, within the performance specifications of the analytical system.

11.3.2 The ratio of ions must agree within 10% with that of the standard.

11.3.3 The retention time of the peak maximum for the ions of interest must exactly match that of the peak.

11.4 Quantitate the CDD and CDF peaks from the response relative to the 37CL-TCSS/F internal standards. Recovery of the internal standard should be greater than 50 percent.

7For cleanup see also method #8320 or #8330, SW‑846, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (1982).

11.5 If a response is obtained for the appropriate set of ions, but is outside the expected ratio, a co‑eluting impurity may be suspected. In this case, another set of ions characteristic of CDD/CDF molecules should be analyzed. For TCDD a good choice of ions is m/e 259. For TCDF a good choice of ions is m/e 241 and 243. These ions are useful in charterizing the molecular structure to TCDD or TCDF. For analysis of TCDD good analytical technique would require using all four ions, m/e 257, 320, 322, and 328, to verify detection and signal to noise ratio of 5 to 1. Suspected impurities such as DDE, DDD or PCB residues can be confirmed cy checking for their major fragments. These materials can be removed by the cleanup columns. Failure to meet criteria should be explained in the report, or the sample reanalyzed.

11.6 If broad background interference restricts the sensitivity of the GC/MS analysis, the analyst should employ cleanup procedures and reanalyze by GC/MS. See Section 10.0.

11.7 In those circumstances where these procedures do not yield a definitive conclusion, the use of high resolution mass spectrometry is suggested.

12. Calculations

12.1 Determine the concentration of individual compounds according to the formula:

A x As

Concentration, ug/gm = _____________

G x Ais Rf

where:

A=ug of internal standard added to the sample8.

G=gm of sample extracted.

As=area of characteristic ion of the compound being quantified.

Ais=area of characteristic ion of the internal standard.

Rf=response factor9.

8The proper amount of standard to be used is determined from the calibration curve (See Section 6.0).

9If standards for PCDDs/Fs and HxCDDs/Fs are not available, response factors for ions derived from these congeners are calculated relative to 37CL‑TCDD/F. The analyst may use response factors for 1,2,3,4‑ or 2,3,7,8‑TCDD, 1,2,3,4,7‑PeCDD, or 1,2,3,4,7,8‑HxCDDs/Fs, respectively. Implicit in this requirement is the assumption that the same response is obtained from PCDDs/Fs containing the same numbers of chlorine atoms.

Response factors are calculated using data obtained from the analysis of standards according to the formula:

As x Cis

RF = _____________

Ais x Cs

where:

Cis=concentration of the internal standard.

Cs=concentration of the standard compound.

12.2 Report results in micrograms per gram without correction for recovery data. When duplicate and spiked samples are analyzed, all data obtained should be reported.

12.3 Accuracy and Precision. No data available at this time.

1Detection limit for liquid samples is 0.003 ug/l. This is calculated from the minimum detectable GC response being equal to five times the GC background noise assuming a l ml effective final volume of the 1 liter sample extract, and a GC injection of 5 microliters. Detection levels apply to both electron capture and GC/MS detection. For further details see 44 FR 69526 (December 3, 1979).
