—POLYCHLORI NATED BIPHENYLS (PCBs) MANUFACTURI NG, PROCESSI

NG, DI STRIBUTION IN COMMERCE, AND USE PROHIBITIONS Subpart A

— General § 761.1 Applicability

. (a) This part establishes prohibitions of, and requirements for, the manufacture, processing, distribution in commerce, use, disposal, storage, and marking of PCBs and PCB Items. (b)(1) This part applies to all persons who manufacture, process, distribute in commerce, use, or dispose of PCBs or PCB Items. Substances that are regulated b y this part include, but are not limited to: dielectric fluids; solvents; oils; waste oils; heat transfer fluids; hydraulic fluids; paints or coatings; sludges; slurries; sediments; dredge spoils; soils; materials containing PCBs as a result of spills; and other chem ical substances or combinations of substances, including impurities and by

products and an y b yproduct, intermediate, or impurit y manufactured at an y point in a process. (2) Unless otherwise noted, PCB concentrations shall be determined on a weight

- per - weight basis (e.g., milligrams per kilogram), or for liquids, on a weight

- per - volume basis (e.g., milligrams per liter) if the density of the liquid is also reported. Unless otherwise provided, PCBs are quantified based on the formulation of PCBs present in th e material analyzed. For example, measure AroclorTM 1242 PCBs based on a comparison with AroclorTM 1242 standards. Measure individual congener PCBs based on a comparison with individual PCB congener standards. (3) Most provisions in this part appl y only i f PCBs are present in concentrations above a specified level. Provisions that apply to PCBs at concentrations of < 50 ppm apply also to contaminated surfaces at PCB concentrations of  10  g/100 cm 2. Provisions that apply to PCBs at concentrations of  50 to < 500 ppm apply also to contaminated surfaces at PCB concentrations of > 10/100 cm 2 to < 100  g/100 cm 2. Provisions that apply to PCBs at concentrations of  500 ppm apply also to contaminated surfaces at PCB concentrations of  100  g/100 cm 2. (4) PCBs can be found in liquid, non

- liquid and multi

- phasic (combinations of liquid and non

liquid) forms. A person should use the following criteria to determine PCB concentrations to determine which provisions of this part apply to such PCBs. (i) An y perso n determining PCB concentrations for non

- liquid PCBs must do so on a dry weight basis. (ii) Any person determining PCB concentrations for liquid PCBs must do so on a wet weight basis. L iquid PCBs containing more than 0.5 percent by weight non

- dissolved material shall be anal yz ed as multi

- phasic non

- liquid/liquid mixtures.(iii) Any

person determining the PCB concentration of samples containing PCBs and non

dissolved non

- liquid materials  0.5 percent, must separate the non

- dissolved materials into non

liqu id PCBs and liquid PCBs. For multi

- phasic non

- liquid/liquid or liquid/liquid mixtures, the phases shall be separated before chemical anal ys is. Following phase separation, the PCB concentration in each non

- liquid phase shall be determined on a dry weight ba sis and the PCB concentration in each liquid phase shall be determined separatel y on a wet weight basis. (iv) An y person disposing of multi

- phasic non

- liquid/liquid or liquid/liquid mixtures must use the PCB disposal requirements that apply to the individ

ual phase with the highest PCB concentration except where otherwise noted. Alternatively , phases may be separated and disposed of using the PCB disposal requirements that apply to each separated, single

- phase material. (5) No person may

avoid any

provisio n specifying a PCB concentration by diluting the PCBs, unless otherwise specifically provided. (6) Unless otherwise specified, references to weights or volumes of PCBs in this part apply to the total weight or total volume of the material (oil, soil, debr is, etc.) that contains regulated concentrations of PCBs, not the calculated weight or volume of only the PCB molecules contained in the material. (c) Definitions of the terms used in these regulations are in subpart A. The basic requirements applicable t o disposal and marking of PCBs and PCB Items are set forth in subpart D

—Disposal of PCBs and PCB Items and in subpart C

—Marking of PCBs and PCB Items. Prohibitions applicable to PCB activities are set forth in subpart B

—Manufacture, Processing, Distributio n in Commerce, and Use of PCBs and PCB Items. Subpart B also includes authorizations from the prohibitions. Subparts C and D set forth the specific requirements for disposal and marking of PCBs and PCB Items. (d) Section 15 of the Toxic Substances Control Act (TSCA) states that failure to comply with these regulations is unlawful. Section 16 imposes liability for civil penalties upon any person who violates these regulations, and the Administrator can establish appropriate remedies for any violations subje ct to any

limitations included in section 16 of TSCA. Section 16 also subjects a person to criminal prosecution for a violation which is knowing or willful. In addition, section 17 authorizes Federal district courts to enjoin activities prohibited by these regulations, compel the taking of actions required by these regulations, and issue orders to seize PCBs and PCB Items manufactured, processed or distributed in violation of these regulations. (e) These regulations do not preempt other more stringent Fede ral statutes and regulations. (f) Unless and until superseded b y an y new more stringent regulations issued under EPA authorities, or an y permits or an y pretreatment requirements issued by EPA, a state or local government that affect release of PCBs to an y particular medium: (1) Persons who inadvertently manufacture or import PCBs generated as unintentional impuritiesin excluded manufacturing processes, as defined in §761.3, are exempt from the requirements of

subpart B of this part, provided that such pe rsons comply with subpart J of this part, as applicable. (2) Persons who process, distribute in commerce, or use products containing PCBs generated in excluded manufacturing processes defined in §761.3 are exempt from the requirements of subpart B provide d that such persons compl y with subpart J of this part, as applicable. (3) Persons who process, distribute in commerce, or use products containing recy cled PCBs defined in §761.3, are exempt from the requirements of subpart B of this part, provided that s uch persons compl y with subpart J of this part, as applicable. (4) Except as provided in §761.20 (d) and (e), persons who process, distribute in commerce, or use products containing excluded PCB products as defined in §761.3, are exempt from the requireme nts of subpart B of this part.

—Manufacturing, P rocessing, Distribution in Commerce, and Use of PCBs and PCB Items § 761.20 Prohibitions and exceptions. Except as authorized in §761.30, the activities listed in paragraphs (a) and (d) of this section are prohibited pursuant to section 6(e)(2) of TSCA . The requirements set forth in paragraph (c) of this section and subpart F of this part concerning export and import of PCBs and PCB Items for disposal are established pursuant to section 6(e)(1) of TSCA. Subject to any exemptions granted pursuant to sect ion 6(e)(3)(B) of TSCA, the activities listed in paragraphs (b) and (c) of this section are prohibited pursuant to section (6)(e)(3)(A) of TSCA. In addition, the Administrator hereb y finds, under the authority of section 12(a)(2) of TSCA, that the manufact ure, processing, and distribution in commerce of PCBs at concentrations of 50 ppm or greater and PCB Items with PCB concentrations of 50 ppm or greater present an unreasonable risk of injury to health within the United States. This finding is based upon th e well

- documented human health and environmental hazard of PCB exposure, the high probability of human and environmental exposure to PCBs and PCB Items from manufacturing, processing, or distribution activities; the potential hazard of PCB exposure posed b y the transportation of PCBs or PCB Items within theUnited States; and the evidence that contamination of the environment b y PCBs is spread far

bey ond the areas where they are used. In addition, the Administrator hereby finds, for purposes of section 6(e) (2)(C) of TSCA, that any exposure of human beings or the environment to PCBs, as measured or detected by an y s cientificall y acceptable anal yt ical method, may be significant, depending on such factors as the quantity of PCBs involved in the exposure, the li kelihood of exposure to humans and the environment, and the effect of exposure. For purposes of determining which PCB Items are totall y enclosed, pursuant to section 6(e)(2)(C) of TSCA, since exposure to such Items may be significant, the Administrator fur ther finds that a totally enclosed manner is a manner which results in no exposure to humans or the environment to PCBs. The following activities are considered totally enclosed: distribution in commerce of intact, nonleaking electrical equipment such as transformers (including transformers used in railway locomotives and self

- propelled cars), capacitors, electromagnets, voltage regulators, switches (including sectionalizers and motor starters), circuit breakers, reclosers, and cable that contain PCBs at an y concentration and processing and distribution in commerce of PCB Equipment containing an intact, nonleaking PCB Capacitor. See paragraph (c)(1) of this section for provisions allowing the distribution in commerce of PCBs and PCB Items. (a) No persons ma y use any PCB, or any

PCB Item regardless of concentration, in any manner other than in a totally

enclosed manner within the United States unless authorized under §761.30, except that: (1) An authorization is not required to use those PCBs or PCB Items wh ich consist of excluded PCB products as defined in §761.3. (2) An authorization is not required to use those PCBs or PCB Items resulting from an excluded manufacturing process or recy cled PCBs as defined in §761.3, provided all applicable conditions of §7 61.1(f) are met. (3) An authorization is not required to use those PCB Items which contain or whose surfaces have been in contact with excluded PCB products as defined in §761.3. (4) An authorization is not required to use sewage sludge where the uses are regulated at parts 257, 258, and 503 of this chapter. No person may blend or otherwise dilute PCBs regulated for disposal, including PCB sewage sludge and sewage sludge not used pursuant to parts 257, 258, and 503 of this chapter, for purposes of use o r to avoid disposal requirements under this part. Except as explicitly

provided in subpart D of this part, no person may dispose of regulated PCB wastes including, but not limited to, PCB remediation waste, PCB bulk product waste, PCBs, and PCB industrial sludges, into treatment works, as defined in §503.9(aa) of this chapter. (b) No person may

manufacture PCBs for use within the United States or manufacture PCBs for export from the United States without an exemption, except that: an exemption is not requi red for PCBs manufactured in an excluded manufacturing process as defined in §761.3, provided all applicable conditions of §761.1(f) are met. (c) No persons may

process or distribute in commerce any PCB, or any

PCB Item regardless of concentration, for us e within the United States or for export from the United States without anexemption, except that an exemption is not required to process or distribute in commerce PCBs

or PCB Items resulting from an excluded manufacturing process as defined in §761.3, or to process or distribute in commerce recy cled PCBs as defined in §761.3, or to process or distribute in commerce excluded PCB products as defined in §761.3, provided that all applicable conditions of §761.1(f) are met. In addition, the activities described in paragraphs (c) (1) through (5) of this section may

also be conducted without an exemption, under the conditions specified therein. (1) PCBs at concentrations of 50 ppm or greater, or PCB Items with PCB concentrations of 50 ppm or greater, sold before July 1, 1979 for purposes other than resale may be distributed in commerce onl y in a totally enclosed manner after that date. (2) An y person may

process and distribute in commerce for disposal PCBs at concentrations of  50 ppm, or PCB Items with PCB conce ntrations of  50 ppm, if they comply with the applicable provisions of this part. (i) Processing activities which are primaril y associated with and facilitate storage or transportation for disposal do not require a TSCA PCB storage or disposal approval. (ii) Processing activities which are primaril y associated with and facilitate treatment, as defined in §260.10 of this chapter, or disposal require a TSCA PCB disposal approval unless they are part of an existing approval, are part of a self

- implementing a ctivity

under §761.61(a) or §761.79 (b) or (c), or are otherwise specifically allowed under subpart D of this part. (iii) With the exception of provisions in §761.60 (a)(2) and (a)(3), in order to meet the intent of §761.1(b), processing, diluting, or oth erwise blending of waste prior to being introduced into a disposal unit for purposes of meeting a PCB concentration limit shall be done in accordance with a TSCA PCB disposal approval or compl y with the requirements of §761.79. (iv) Where the rate of deli vering liquids or non

- liquids into a PCB disposal unit is an operating parameter, this rate shall be a condition of the TSCA PCB disposal approval for the unit when an approval is required. (3) PCBs and PCB Items may be exported for disposal in accordance with the requirements of subpart F of this part. (4) PCBs, at concentrations of less than 50 ppm, or PCB Items, with concentrations of less than 50 ppm, may

be processed and distributed in commerce for purposes of disposal. (5) Decontaminated materials. Any person may

distribute in commerce equipment, structures, or other liquid or non

- liquid materials that were contaminated with PCBs  50 ppm, including those not otherwise authorized for distribution in commerce under this part, provided that one of the f ollowing applies: (i) The materials were decontaminated in accordance with a TSCA PCB disposal approval issued under subpart D of this part, with §761.79, or with applicable EPA PCB spill cleanup policies in effect at the time of the decontamination.(ii ) If not previousl y decontaminated, the materials now meet an applicable decontamination

standard in §761.79(b). (d) The use of waste oil that contains an y detectable concentration of PCB as a sealant, coating, or dust control agent is prohibited. Prohibi ted uses include, but are not limited to, road oiling, general dust control, use as a pesticide or herbicide carrier, and use as a rust preventative on pipes. (e) In addition to any

applicable requirements under 40 CFR part 279, subparts G and H, marketers and burners of used oil who market (process or distribute in commerce) for energy recovery , used oil containing an y quantifiable level of PCBs are subject to the following requirements: (1) Restrictions on marketing. Used oil containing any quantifiable level of PCBs (2 ppm) may be marketed onl y to: (i) Qualified incinerators as defined in 40 CFR 761.3. (ii) Marketers who market off

- specification used oil for energy recovery only to other marketers who have notified EPA of their used oil manage ment activities, and who have an EPA identification number where an identification number is required b y 40 CFR 279.73. This would include persons who market off

- specification used oil who are subject to the requirements at 40 CFR part 279 and the notification requirements of 40 CFR 279.73. (iii) Burners identified in 40 CFR 279.61(a)(1) and (2). Onl y burners in the automotive industry may burn used oil generated from automotive sources in used oil

- fired space heaters provided the provisions of 40 CFR 279. 23 are met. The Regional Administrator may grant a variance for a boiler that does not meet the 40 CFR 279.61(a)(1) and (2) criteria after considering the criteria listed in 40 CFR 260.32 (a) through (f). The applicant must address the relevant criteria co ntained in 40 CFR 260.32 (a) through (f) in an application to the Regional Administrator. (2) Testing of used oil fuel. Used oil to be burned for energy recovery is presumed to contain quantifiable levels (2 ppm) of PCB unless the marketer obtains anal ys e s (testing) or other information that the used oil fuel does not contain quantifiable levels of PCBs. (i) The person who first claims that a used oil fuel does not contain quantifiable level (2 ppm) PCB must obtain analy ses or other information to support that claim. (ii) Testing to determine the PCB concentration in used oil may be conducted on individual samples, or in accordance with the testing procedures described in §761.60(g)(2). However, for purposes of this part, if any PCBs at a concentration of 50 ppm or greater have been added to the container or equipment, then the total container contents must be considered as having a PCB concentration of 50 ppm or greater for purposes of complying with the disposal requirements of this part.(iii) Other in formation documenting that the used oil fuel does not contain quantifiable levels (2

ppm) of PCBs may

consist of either personal, special knowledge of the source and composition of the used oil, or a certification from the person generating the used oil cl aiming that the oil contains no detectable PCBs. (3) Restrictions on burning. (i) Used oil containing an y quantifiable levels of PCB may be burned for energy

recovery onl y in the combustion facilities identified in paragraph (e)(1) of this section when su ch facilities are operating at normal operating temperatures (this prohibits feeding these fuels during either startup or shutdown operations). Owners and operators of such facilities are “burners” of used oil fuels. (ii) Before a burner accepts from a marketer the first shipment of used oil fuel containing detectable PCBs (2 ppm), the burner must provide the marketer a one

- time written and signed notice certifying that: (A) The burner has complied with any notification requirements applicable to “qualifi ed incinerators” (§761.3) or to “burners” regulated under 40 CFR part 279, subpart G. (B) The burner will burn the used oil only in a combustion facility

identified in paragraph (e)(1) of this section and identify the class of burner he qualifies. (4) Re cordkeeping requirements. The following recordkeeping requirements are in addition to the recordkeeping requirements for marketers found in 40 CFR 279.72(b), 279.74(a), (b) and (c), and 279.75, and for burners found in 40 CFR 279.65 and 279.66. (i) Marketers. Marketers who first claim that the used oil fuel contains no detectable PCBs must include among the records required b y 40 CFR 279.72(b) and 279.74(b) and (c), copies of the anal ys is or other information documenting his claim, and he must includ e among the records required b y 40 CFR 279.74(a) and (c) and 279.75, a cop y of each certification notice received or prepared relating to transactions involving PCB

- containing used oil. (ii) Burners. Burners must include among the records required b y 40 C FR 279.65 and 279.66, a copy of each certification notice required by paragraph (e)(3)(ii) of this section that he sends to a marketer. (Sec. 6, Pub. L . 94

- applicable sampling requirements b y presuming that the PCBs d isposed of are  500 ppm (or  100  g/100 cm2 if no free

- flowing liquids are present). (6) An y person storing or disposing of PCBs is also responsible for determining and complying with all other applicable Federal, State, and local laws and regulations. ( b) PCB waste. (1) PCB liquids. Any person removing PCB liquids from use (i.e., not PCB remediation waste) must dispose of them in accordance with §761.60(a), or decontaminate them in accordance with §761.79. (2) PCB Items. An y person removing from use a P CB Item containing an intact and non

- leaking PCB Article must dispose of it in accordance with §761.60(b), or decontaminate it in accordance with §761.79. PCB Items where the PCB Articles are no longer intact and non

- leaking are regulated for disposal as P CB bulk product waste under §761.62(a) or (c). (i) Fluorescent light ballasts containing PCBs onl y in an intact and non

- leaking PCB Small Capacitor are regulated for disposal under §761.60(b)(2)(ii). (ii) Fluorescent light ballasts containing PCBs in the potting material are regulated for disposal as PCB bulk product waste under §761.62. (3) PCB remediation waste. PCB remediation waste, including PCB sewage sludge, is regulated for cleanup and disposal in accordance with §761.61. (i) An y person responsi ble for PCB waste at as

- found concentrations  50 ppm that was either placed in a land disposal facility , spilled, or otherwise released into the environment prior to April 18, 1978, regardless of the concentration of the spill or release; or placed in a land disposal facility , spilled, or otherwise released into the environment on or after April 18, 1978, but priorto July

2, 1979, where the concentration of the spill or release was  50 ppm but < 500 ppm, must dispose of the waste as follows: (A) Sites containing these wastes are presumed not to present an unreasonable risk of injury to health or the environment from exposure to PCBs at the site. However, the EPA Regional Administrator may

inform the owner or operator of the site that there is reason to bel ieve that spills, leaks, or other uncontrolled releases or discharges, such as leaching, from the site constitute ongoing disposal that may present an unreasonable risk of injury to health or the environment from exposure to PCBs at the site, and may requi re the owner or operator to generate data necessary

to characterize the risk. If after reviewing any such data, the EPA Regional Administrator makes a finding, that an unreasonable risk exists, then he or she may direct the owner or operator of the site to dispose of the PCB remediation waste in accordance with §761.61 such that an unreasonable risk of injury no longer exists. (B) Unless directed b y the EPA Regional Administrator to dispose of PCB waste in accordance with paragraph (b)(3)(i)(A) of this sec tion, any person responsible for PCB waste at as

- found concentrations  50 ppm that was either placed in a land disposal facility , spilled, or otherwise released into the environment prior to April 18, 1978, regardless of the concentration of the spill or r elease; or placed in a land disposal facility , spilled, or otherwise released into the environment on or after April 18, 1978, but prior to July 2, 1979, where the concentration of the spill or release was  50 ppm but < 500 ppm, who unilaterally decides to dispose of that waste (for example, to obtain insurance or to sell the property), is not required to clean up in accordance with §761.61. Disposal of the PCB remediation waste must comply with §761.61. However, cleanup of those wastes that is not in compl ete compliance with §761.61 will not afford the responsible party with relief from the applicable PCB regulations for that waste. (ii) Any person responsible for PCB waste at as

- found concentrations  50 ppm that was either placed in a land disposal facility , spilled, or otherwise released into the environment on or after April 18, 1978, but prior to July 2, 1979, where the concentration of the spill or release was  500 ppm; or placed in a land disposal facility , spilled, or otherwise released into the environment on or after July

2, 1979, where the concentration of the spill or release was  50 ppm, must dispose of it in accordance with either of the following: (A) In accordance with the PCB Spill Cleanup Policy (Policy) at subpart G of this part, for those PCB remediation wastes that meet the criteria of the Policy . Consult the Policy for a description of the spills it covers and its notification and timing requirements. (B) In accordance with §761.61. Complete compliance with §761.61 does not create a presumption against enforcement action for penalties for an y unauthorized PCB disposal. (iii) The owner or operator of a site containing PCB remediation waste has the burden of proving the date that the w aste was placed in a land disposal facility , spilled, or otherwise released into the environment, and the concentration of the original spill. (4) PCB bulk product waste

— (i) General. An y person disposing of PCB bulk product waste must do so in accordance with §761.62. PCB bulk product waste, as that term is defined in §761.3, is waste that was  50 ppm when originally removed from service, even if its currentPCB concentration is <50 ppm. PCB bulk product waste is regulated for disposal based on the

risk fr om the waste once disposed of. For waste which is land disposed, the waste is regulated based on how readil y the waste is released from disposal to the environment, in particular b y leaching out from the land disposal unit. (ii) Metal surfaces in contact with PCBs. Any person disposing of metal surfaces in contact with PCBs (e.g., painted metal) may use thermal decontamination procedures in accordance with §761.79(c)(6) (see §761.62(a)(6)). (5) PCB household waste. Any person storing or disposing of PCB h ousehold waste, as that term is defined in §761.3, must do so in accordance with §761.63. (6) PCB research and development waste. An y person disposing of PCB wastes generated during and as a result of research and development for use under §761.30(j), or for disposal under §761.60(j), must do so in accordance with §761.64. (7) PCB/Radioactive waste.

(ii) Any person disposing of PCB/radioactive waste must do so taking into account both its PCB concentration and its radioactive properties. If, taking into account only the properties of the PCBs in the waste (and not the radioactive properties of the waste), the waste meets the requirements for disposal in a facility permitted, licensed, or registered by a State as a municipal or non - municipal non

- hazardous waste landfill (e.g., PCB bulk product waste under §761.62(b)(1)), then the person may dispose of the PCB/radioactive waste, without regard to the PCB component of the waste, on the basis of its radioactive properties in accordance with all applicable requirements for the radioactive component of th e waste. (8) Porous surfaces. In most cases a person must dispose of porous surfaces as materials where PCBs have penetrated far beneath the surface, rather than a simple surface contamination. Any person disposing of porous surfaces on which PCBs have be en spilled and meeting the definition of PCB remediation waste at §761.3 must do so in accordance with §761.61. Any person disposing of porous surfaces which are part of manufactured non

- liquid products containing PCBs and meeting the definition of PCB bul k product waste at §761.3 must do so in accordance with §761.62. Any

person may

decontaminate concrete surfaces upon which PCBs have been spilled in accordance with §761.79(b)(4), if the decontamination procedure is commenced within 72 hours of the initial spill of PCBs to the concrete or portion thereof being decontaminated. An y person may

decontaminate porous non

- liquid PCBs in contact with non

- porous surfaces, such as underground metal fuel tanks coated with fire retardant resin or pitch, for purposes of unrestricted use or disposal in a smelter in accordance with §761.79(b)(3). (c) Storage for disposal. Any person who holds PCB waste must store it in accordance with §761.65. (d) Performance specifications for disposal technologies

This common container option does not permit dilution of the collected oil. Mineral oil that is assumed or known to contain at least 50 ppm PCBs must not be mixed with mineral oil that is known or assumed to contain les s than 50 ppm PCBs to reduce the concentration of PCBs in the common container. If dielectric fluid from untested, oil

- filled circuit breakers, reclosers, or cable is collected in a common container with dielectric fluid from other oil

- filled electrical eq uipment, the entire contents of the container must be treated as PCBs at a concentration of at least 50 ppm, unless all of the fluid from the other oil

- filled electrical equipment has been tested and shown to contain less than 50 ppm PCBs. (ii) For purpos es of complying with the marking and disposal requirements, representative samples may

be taken from either the common containers or the individual electrical equipment to determine the PCB concentration, except that if any PCBs at a concentration of 500 p pm or greater have been added to the container or equipment then the total container contents must be considered as having a PCB concentration of 500 ppm or greater for purposes of compl yi ng with the disposal requirements of this subpart. For purposes of this subparagraph, representative samples of mineral oil dielectric fluid are either samples taken in accordance with ASTM D 923

– 86 or ASTM D 923

– 89 or samples taken from a container that has been thoroughl y mixed in a manner such that an y PCBs in the conta iner are uniformly distributed throughout the liquid in the container. (iii) Unless otherwise specified in this part, an y person conducting the chemical anal ys is of PCBs shall do so using gas chromatograph y.

- waste oils, are added to the container. (ii) For purposes of complying with the marking and disposal requirements, representative samples may

be taken from either the common containers or the individual electrical equipment to determine the PCB concentration. Except, That if any PCBs at a concentration of 500 ppm or greater have been added to the container or equipment then the total container contents must be considered as having a PCB concentration of 500 ppm or greater for purposes of compl yi ng with the disposal re quirements of this subpart. For purposes of this paragraph, representative samples of mineral oil dielectric fluid are either samples taken in accordance with ASTM D 923

– 86 or ASTM D 923

– 89 or samples taken from a container that has been thoroughly mixed i n a manner such that an y PCBs in the container are uniforml y distributed throughout the liquid in the container. (iii) Unless otherwise specified in this part, an y person conducting the chemical anal ys is of PCBs shall do so using gas chromatograph y. An y g as chromatographic method that is appropriate for the material being anal yz ed may be used, including those indicated in paragraph (g)(1)(iii) of this section. (h) Requirements for export and import of PCBs and PCB Items for disposal are found in Subpart F of this part. (i) Approval authority

for disposal methods. (1) The officials (the Director, National Programs Chemical Division and the Regional Administrators) designated in §§761.60(e) and 761.70 (a) and (b) to receive requests for approval of PCB disp osal activities are the primary approval authorities for these activities.

–469, 90 Stat. 2020 (15 U.S.C. 2605) [44 FR 31542, May

31, 1979] § 761.61 PCB r emediation waste. This section provides cleanup and disposal options for PCB remediation waste. An y person cleaning up and disposing of PCBs managed under this section shall do so based on the concentration at which the PCBs are found. This section does n ot prohibit any person from implementing temporary

emergency

measures to prevent, treat, or contain further releases or mitigate migration to the environment of PCBs or PCB remediation waste. (a) Self

- implementing on

- site cleanup and disposal of PCB remedi ation waste. EPA designed the self

- implementing procedure for a general, moderately

- sized site where there should be low residual environmental impact from remedial activities. The procedure may be less practical for larger or environmentall y diverse sites . For these other sites, the self

- implementing procedure still applies, but an EPA Regional Administrator may authorize more practical procedures through paragraph (c) of this section. Any person may

conduct self

- implementing cleanup and disposal of PCB re mediation waste in accordance with the following requirements without prior written approval from EPA. (1) Applicability . (i) The self

- implementing procedures may not be used to clean up: (A) Surface or ground waters. (B) Sediments in marine and freshwater ecos ys tems. (C) Sewers or sewage treatment sy stems. (D) An y private or public drinking water sources or distribution sy stems.(E) Grazing lands.

(F) Vegetable gardens. (ii) The self

- implementing cleanup provisions shall not be binding upon cleanups conducted under other authorities, including but not limited to, actions conducted under section 104 or section 106 of CERCLA, or section 3004(u) and (v) or section 3008(h) of RCRA. (2) Site characterization. Any person conducting self

- implementi ng cleanup of PCB remediation waste must characterize the site adequately to be able to provide the information required by paragraph (a)(3) of this section. Subpart N of this part provides a method for collecting new site characterization data or for asse ssing the sufficiency of existing site characterization data. (3) Notification and certification. (i) At least 30 day s prior to the date that the cleanup of a site begins, the person in charge of the cleanup or the owner of the propert y where the PCB reme diation waste is located shall notify , in writing, the EPA Regional Administrator, the Director of the State or Tribal environmental protection agency , and the Director of the count y or local environmental protection agency where the cleanup will be conduc ted. The notice shall include: (A) The nature of the contamination, including kinds of materials contaminated. (B) A summary

of the procedures used to sample contaminated and adjacent areas and a table or cleanup site map showing PCB concentrations measured in all pre

- cleanup characterization samples. The summary

must include sample collection and analy sis dates. The EPA Regional Administrator may

require more detailed information including, but not limited to, additional characterization sampling or all sample identification numbers from all previous characterization activities at the cleanup site. (C) The location and extent of the identified contaminated area, including topographic maps with sample collection sites cross referenced to the sample identi fication numbers in the data summary from paragraph (a)(3)(i)(B) of this section. (D) A cleanup plan for the site, including schedule, disposal technology , and approach. This plan should contain options and contingencies to be used if unanticipated higher concentrations or wider distributions of PCB remediation waste are found or other obstacles force changes in the cleanup approach. (E) A written certification, signed b y the owner of the propert y where the cleanup site is located and the part y conducting the cleanup, that all sampling plans, sample collection procedures, sample preparation procedures, extraction procedures, and instrumental/chemical anal ys is procedures used to assess or characterize the PCB contamination at the cleanup site, are on file at the location designated in the certificate, and are available for EPA inspection. Persons using alternate methods for chemical extraction and chemical anal ys is for site characterization must include in the certificate a statement that such a method will be used and that a comparison stud y which meets or exceeds the requirements of subpart Q of this part, and for which records are onfile, has been completed prior to verification sampling.

(ii) Within 30 calendar day s of receiving the notification, the EP A Regional Administrator will respond in writing approving of the self

- implementing cleanup, disapproving of the self

implementing cleanup, or requiring additional information. If the EPA Regional Administrator does not respond within 30 calendar day s of r eceiving the notice, the person submitting the notification may

assume that it is complete and acceptable and proceed with the cleanup according to the information the person provided to the EPA Regional Administrator. Once cleanup is underway , the person conducting the cleanup must provide an y proposed changes from the notification to the EPA Regional Administrator in writing no less than 14 calendar day s prior to the proposed implementation of the change. The EPA Regional Administrator will determine in h is or her discretion whether to accept the change, and will respond to the change notification verball y within 7 calendar days and in writing within 14 calendar days of receiving it. I f the EPA Regional Administrator does not respond verball y within 7 cale ndar day s and in writing within 14 calendar day s of receiving the change notice, the person who submitted it may deem it complete and acceptable and proceed with the cleanup according to the information in the change notice provided to the EPA Regional Adm inistrator. (iii) Any person conducting a cleanup activity may obtain a waiver of the 30

- day notification requirement, if they

receive a separate waiver, in writing, from each of the agencies they are required to notify

under this section. The person must retain the original written waiver as required in paragraph (a)(9) of this section. (4) Cleanup levels. For purposes of cleaning, decontaminating, or removing PCB remediation waste under this section, there are four general waste categories: bulk PCB rem ediation waste, non - porous surfaces, porous surfaces, and liquids. Cleanup levels are based on the kind of material and the potential exposure to PCBs left after cleanup is completed. (i) Bulk PCB remediation waste. Bulk PCB remediation waste includes, but is not limited to, the following non

- liquid PCB remediation waste: soil, sediments, dredged materials, muds, PCB sewage sludge, and industrial sludge. (A) High occupancy

areas. The cleanup level for bulk PCB remediation waste in high occupancy areas is  1 ppm without further conditions. High occupancy areas where bulk PCB remediation waste remains at concentrations >1 ppm and  10 ppm shall be covered with a cap meeting the requirements of paragraphs (a)(7) and (a)(8) of this section. (B) Low occupancy

areas. (1) The cleanup level for bulk PCB remediation waste in low occupancy

areas is  25 ppm unless otherwise specified in this paragraph. (2) Bulk PCB remediation wastes may remain at a cleanup site at concentrations >25 ppm and  50 ppm if the site is secured b y a fence and marked with a sign including the ML mark. (3) Bulk PCB remediation wastes may remain at a cleanup site at concentrations >25 ppm and  100 ppm if the site is covered with a cap meeting the requirements of paragraphs (a)(7) and (a)(8) of this section.(ii) Non

- porous surfaces. In high occupancy areas, the surface PCB cleanup standard is  10  g/100 cm2 of surface area. In low occupancy areas, the surface cleanup standard is <100  g/100 cm2 of surface area. Select sampling locations in accordance with subpart P of this part or a sampling plan approved under paragraph (c) of this section. (iii) Porous surfaces. In both high and low occupancy areas, any

person disposing of porous surfaces must do so based on the levels in paragraph (a)(4 )(i) of this section. Porous surfaces may be cleaned up for use in accordance with §761.79(b)(4) or §761.30(p). (iv) L iquids. In both high and low occupancy areas, cleanup levels are the concentrations specified in §761.79(b)(1) and (b)(2). (v) Change in the land use for a cleanup site. Where there is an actual or proposed change in use of an area cleaned up to the levels of a low occupancy area, and the exposure of people or animal life in or at that area could reasonabl y be expected to increase, resulti ng in a change in status from a low occupancy

area to a high occupancy area, the owner of the area shall clean up the area in accordance with the high occupancy area cleanup levels in paragraphs (a)(4)(i) through (a)(4)(iv) of this section. (vi) The EPA R egional Administrator, as part of his or her response to a notification submitted in accordance with §761.61(a)(3) of this part, may require cleanup of the site, or portions of it, to more stringent cleanup levels than are otherwise required in this sectio n, based on the proximity to areas such as residential dwellings, hospitals, schools, nursing homes, playgrounds, parks, day care centers, endangered species habitats, estuaries, wetlands, national parks, national wildlife refuges, commercial fisheries, an d sport fisheries. (5) Site cleanup. In addition to the options set out in this paragraph, PCB disposal technologies approved under §§761.60 and 761.70 are acceptable for on

PCB household waste, as defined at §761.3, managed in a facility permitted, licens ed, or registered b y a State to manage municipal or industrial solid waste, or in a facility with an approval to dispose of PCB bulk product waste under §761.62(c), is not subject to an y other requirements of part 761 of this chapter. PCB household waste s tored in a unit regulated for storage of PCB waste must not be commingled with PCB waste. [63 FR 35452, June 29, 1998] § 761.64 Disposal of wastes generated as a result of research and development activities authorized under §761.30(j) and chemical ana ly sis of PCBs. This section provides disposal requirements for wastes generated during and as a result ofresearch and development authorized under §761.30(j). This section also provides disposal

requirements for wastes generated during the chemical anal y sis of samples containing PCBs under part 761, including §§761.30, 761.60, 761.61, 761.62, and 761.79. For determining the presence of PCBs in samples, chemical anal ys is includes: sample preparation, sample extraction, extract cleanup, extract concentratio n, addition of PCB standards, and instrumental anal ys is. (a) Portions of samples of a size designated in a chemical extraction and analy sis method for PCBs and extracted for purposes of determining the presence of PCBs or concentration of PCBs are unregul ated for PCB disposal under this part. (b) All other wastes generated during these activities are regulated for disposal based on their concentration at the time of disposal as follows: (1) L iquid wastes, including rinse solvents, must be disposed of according to §761.61(a)(5)(iv). (2) Non

- liquid wastes must be disposed of in the same manner as non

- liquid cleaning materials and personal protective equipment waste according to §761.61(a)(5)(v)(A). [63 FR 35452, June 29, 1998] § 761.65 Storage for d isposal. This section applies to the storage for disposal of PCBs at concentrations of 50 ppm or greater and PCB Items with PCB concentrations of 50 ppm or greater. (a)(1) Storage limitations. Any PCB waste shall be disposed of as required by subpart D o f this part within 1

- ye ar from the date it was determined to be PCB waste and the decision was made to dispose of it. This date is the date of removal from service for disposal and the point at which the 1

- ye ar time frame for disposal begins. PCB/radioacti ve waste removed from service for disposal is exempt from the 1

- ye ar time limit provided that the provisions at paragraphs (a)(2)(ii) and (a)(2)(iii) of this section are followed and the waste is managed in accordance with all other applicable Federal, State, and local laws and regulations for the management of radioactive material. (2) One

- year extension. Any person storing PCB waste that is subject to the 1

- year time limit for storage and disposal in paragraph (a)(1) of this section may provide written n otification to the EPA Regional Administrator for the Region in which the PCB waste is stored that their continuing attempts to dispose of or secure disposal for their waste within the 1

- year time limit have been unsuccessful. Upon receipt of the notice by the EPA Regional Administrator, the time for disposal is automatically extended for 1 additional y ear (2 y ears total) if the following conditions are met: (i) The notification is received b y the EPA Regional Administrator at least 30 days before the init ial 1

- year time limit expires and the notice identifies the storer, the t ypes, volumes, and locations of the waste and the reasons for failure to meet the initial 1

- ye ar time limit. (ii) A written record documenting all continuing attempts to secure dispo sal is maintained untilthe waste is disposed of.

(iii) The written record required by paragraph (a)(2)(ii) of this section is available for inspection or submission if requested by EPA. (iv) Continuing attempts to secure disposal were initiated within 2 70 day s after the time the waste was first subject to the 1

- ye ar time limit requirement, as specified in paragraph (a)(1) of this section. Failure to initiate and continue attempts to secure disposal throughout the total time the waste is in storage shall automatically disqualify

the notifier from receiving an automatic extension under this section. (3) Additional extensions. Upon written request, the EPA Regional Administrator for the Region in which the wastes are stored or the Director, National Program Chemicals Division, may grant additional extensions beyond the 1

- year extension authorized in paragraph (a)(2) of this section. At the time of the request, the requestor must supply specific justification for the additional extension and indicate what mea sures the requestor is taking to secure disposal of the waste or indicate wh y disposal could not be conducted during the period of the prior extension. The EPA Regional Administrator or the Director, National Program Chemicals Division may require, as a co ndition to granting an y extension under this section, specific actions including, but not limited to, marking, inspection, recordkeeping, or financial assurance to ensure that the waste does not pose an unreasonable risk of injury to health or the environm ent. (4) Storage at an approved facility . Increased time for storage may be granted as a condition of any TSCA PCB storage or disposal approval, by the EPA Regional Administrator for the Region in which the PCBs or PCB Items are to be stored or disposed o f, or b y the Director, National Program Chemicals Division, if EPA determines that there is a demonstrated need or justification for additional time, that the owner or operator of the facilit y is pursuing relevant treatment or disposal options, and that no unreasonable risk of injury to health or the environment will result from the increased storage time. In making this determination, EPA will consider such factors as absence of an y approved treatment technology and insufficient time to complete the treatm ent or destruction process. EPA may require as a condition of the approval that the owner or operator submit periodic progress reports. (b) Except as provided in paragraphs (b)(2), (c)(1), (c)(7), (c)(9), and (c)(10) of this section, after July 1, 1978, o wners or operators of any facilities used for the storage of PCBs and PCB Items designated for disposal shall comply with the following storage unit requirements: (1) The facilities shall meet the following criteria: (i) Adequate roof and walls to prevent rain water from reaching the stored PCBs and PCB Items; (ii) An adequate floor that has continuous curbing with a minimum 6 inch high curb.

The closure cost estimate shall be in writing, be certified by the person preparing it (using the certification defined in §761.3) and compl y with all of the following criteria: (i) The closure cost estimate shall equal the cost of final closure at the point in the PCB storage facility 's active life when the extent and manner of PCB storage operations would make closure the most expensive, as indicated b y the facility's closure plan. (ii) The closure cost estimate shall be based on the costs to the owner or operator of hiring a third party to close the facility , and the third part y shall not be either a corporate parent or subsidiary of the own er or operator, or member in joint ownership of the facility

.(iii) The owner or operator shall include in the estimate the current market costs for off

- site commercial disposal of the facilit y's maximum estimated inventory of PCB wastes, except that on - s ite disposal costs may be used if on

- site disposal capacity will exist at the facilit y at all times over the life of the PCB storage facility

. (iv) The closure cost estimate may not incorporate an y salvage value that may be realized with the sale of waste s, facility structures or equipment, land, or other assets associated with the facility at the time of closure. (2) During the active life of the PCB storage facility , the commercial storer of PCB waste shall adjust annually

for inflation the closure cost estimate within 60 day s prior to the anniversary date of the establishment of the financial instruments used to demonstrate financial responsibility for closure, except that owners or operators who use the financial test or corporate guarantee shall adjus t their closure cost estimates for inflation within 30 day s after the close of the storer's fiscal ye ar. The adjustment may be made by

recalculating the maximum costs of closure in current dollars, or b y using an inflation factor derived from the most rece nt Implicit Price Deflator for Gross National Product published by the U.S. Department of Commerce in its Survey of Current Business. The Implicit Price Deflator for Gross National Product is included in a monthly publication titled Economic Indicators, wh ich is available from the Superintendent of Documents, Government Printing Office, Washington, DC 20402. The inflation factor used in the latter method is the result of dividing the latest published annual Deflator by the Deflator for the previous year. Th e adjustment to the closure cost estimate is then made by multiplying the most recent closure cost estimate by the latest inflation factor. (3) Where the Regional Administrator (or the Director, National Programs Chemical Division, if he approved the clos ure plan) approves a modification to the facility 's closure plan, and that modification increases the cost of closure, the owner or operator shall revise the closure cost estimate no later than 30 day s after the modification is approved. Any such revision shall also be adjusted for inflation in accordance with paragraph (f)(2) of this section. (4) The owner or operator of the facility shall keep at the facilit y during its operating life the most recent closure cost estimate, including an y adjustments resul ting from inflation or from modifications to the closure plan. (g) Financial assurance for closure. A commercial storer of PCB waste shall establish financial assurance for closure of each PCB storage facility that he owns or operates. In establishing fin ancial assurance for closure, the commercial storer of PCB waste may choose from the following financial assurance mechanisms or an y combination of mechanisms: (1) The “closure trust fund,” as specified in §264.143(a) of this chapter, except for paragraph (a)(3) of §264.143. For purposes of this paragraph, the following provisions also apply : (i) Pay ments into the trust fund shall be made annually by the owner or operator over the remaining operating life of the facility as estimated in the closure plan, or over 3 y ears, whichever period is shorter. This period of time is hereafter referred to as the “pay

- in period.”For an existing facility , the first pay ment must be made within 30 calendar day s after EPA has notified the facility

of its conditional appro val. Interim approval to operate is canceled and the application is denied if EPA does not receive verification that the pay ment was made in that 30

- day period. (ii) For a new facility , the first pay ment into the closure trust fund shall be made before EP A grants final approval of the application and before the facility may accept the initial shipment of PCB waste for commercial storage. A receipt from the trustee shall be submitted by the owner or operator to the Regional Administrator (or the Director, N ational Programs Chemical Division, if the commercial storage area is ancillary to a disposal facility

approved b y the Director CMD) before this initial delivery of PCB waste. The first pay ment shall be at least equal to the current closure cost estimate, divided by the number of y ears in the pay

- in period, except as provided in paragraph (g)(7) of this section for multiple mechanisms. Subsequent payments shall be made no later than 30 day s after each anniversary date of the first pay

ment. The amount of eac h subsequent pay

ment shall be determined by subtracting the current value of the trust fund from the current closure cost estimate, and dividing this difference b y the number of years remaining in the pay

- in period. (iii) If an owner or operator of a faci lity existing on the effective date of this paragraph establishes a trust fund to meet the financial assurance requirements of this paragraph, and the value of the trust fund is less than the current closure cost estimate when a final approval is granted f or the facility , the amount of the current closure cost estimate still to be paid into the trust fund shall be paid in over the pay

- in period as defined in paragraph (g)(1)(i) of this section. Pay ments shall continue to be made no later than 30 day s after each anniversary date of the first pay ment made into the trust fund. The amount of each pay ment shall be determined by subtracting the current value of the trust fund from the current closure cost estimate, and dividing this difference b y the number of ye ars remaining in the pay

- in period. (iv) The submission of a trust agreement with the wording specified in §264.151(a)(1) of this chapter, including an y reference to hazardous waste management facilities, shall be deemed to be in compliance with the requir ement to submit a trust agreement under this subpart. (2) The “suret y bond guaranteeing payment into a closure trust fund,” as specified in §264.143(b) of this chapter, including the use of the suret y bond instrument specified at §264.151(b) of this chapter and the standb y trust specified at §264.143(b)(3) of this chapter. The use of the suret y bonds, surety bond instruments, and standby trust agreements specified in §§264.143(b) and 264.151(b) of this chapter shall be deemed to be in compliance with this subpart.

The submission and use of the surety bond instrument specified at §264.151(c) of this chapter and the standby trust specified at §264.143(c)(3) of this chapter shall be deemed to be in compliance with the requirements under this subpart relating to the use of surety bonds and standby

trust funds. (ii) For the purposes of this para graph, and under the terms of the bond, the surety shall becomeliable on the bond obligation when the owner or operator fails to perform as guaranteed by the bond. L iability

is established by

a final administrative determination pursuant to section 16 of TSCA that the owner or operator has failed to perform final closure in accordance with the closure plan and other approval or regulatory requirements when required to do so. (4)(i) The “closure letter of credit” specified in §264.143(d) of this chapter, e xcept for paragraph (d)(8). The submission and use of the irrevocable letter of credit instrument specified in §264.151(d) of this chapter and the standb y trust specified in §264.143(d)(3) of this chapter shall be deemed to be in compliance with the requir ements of this subpart relating to the use of letters of credit and standb y trust funds. (ii) For the purposes of this paragraph, the Regional Administrator (or the Director, National Programs Chemical Division, if the commercial storage area is ancillary to a disposal facility approved b y the Director, National Programs Chemical Division) may draw on the letter of credit following a final administrative determination pursuant to section 16 of TSCA that the owner or operator has failed to perform final clo sure in accordance with the closure plan and other approval or regulatory requirements when required to do so. (5) “Closure insurance,” as specified in §264.143(e) of this chapter, utilizing the certificate of insurance for closure specified at §264.151(e ) of this chapter.

- year floodwater elevation, the operator sha ll provide surface water diversion dikes around the perimeter of the landfill site with a minimum height equal to two feet above the 100

- ye ar floodwater elevation. (ii) If the landfill site is above the 100

- ye ar floodwater elevation, the operators shall p rovide diversion structures capable of diverting all of the surface water runoff from a 24

- hour, 25

- ye ar storm. (5) Topograph y. The landfill site shall be located in an area of low to moderate relief to minimize erosion and to help prevent landslides or s lumping. (6) Monitoring s ys tems

— (i) Water sampling. (A) For all sites receiving PCBs, the ground and surface water from the disposal site area shall be sampled prior to commencing operations under an approval provided in paragraph (c) of this section for u se as baseline data. (B) An y surface watercourse designated b y the Regional Administrator using the authority provided in paragraph (c)(3)(ii) of this section shall be sampled at least monthly when the landfill is being used for disposal operations. (C) An y surface watercourse designated b y the Regional Administrator using the authority provided in paragraph (c)(3)(ii) of this section shall be sampled for a time period specified b y the Regional Administrator on a frequency of no less than once every six m onths after final closure of the disposal area. (ii) Groundwater monitor wells. (A) If underl yi ng earth materials are homogenous, impermeable, and uniformly

sloping in one direction, onl y three sampling points shall be necessary. These three points shall be equally spaced on a line through the center of the disposal area and extending from the area of highest water table elevation to the area of the lowest water table elevation on the propert y. (B) All monitor wells shall be cased and the annular space be tween the monitor zone (zone of saturation) and the surface shall be completel y backfilled with Portland cement or an equivalent material and plugged with Portland cement to effectively prevent percolation of surface water into the well bore. The well open ing at the surface shall have a removable cap to provide access and to prevent entrance of rainfall or stormwater runoff. The well shall be pumped to remove thevolume of liquid initially contained in the well before obtaining a sample for anal ys is. The di scharge shall be treated to meet applicable State or Federal discharge standards or recycled to the chemical waste landfill. (iii) Water anal ys is. As a minimum, all samples shall be anal yz ed for the following parameters, and all data and records of the sampling and analy sis shall be maintained as required in §761.180(d)(1). Sampling methods and anal yt ical procedures for these parameters shall comply with those specified in 40 CFR part 136 as amended in 41 FR 52779 on December 1, 1976. (A) PCBs. (B) pH. (C) Specific conductance. (D) Chlorinated organics. (7) Leachate collection. A leachate collection monitoring s ys tem shall be installed above the chemical waste landfill. Leachate collection sy stems shall be monitored monthly for quantity

and phy sicochemical characteristics of leachate produced. The leachate should be either treated to acceptable limits for discharge in accordance with a State or Federal permit or disposed of b y another State or Federally approved method. Water anal ys is shall b e conducted as provided in paragraph (b)(6)(iii) of this section. Acceptable leachate monitoring/collection sy stems shall be any of the following designs, unless a waiver is obtained pursuant to paragraph (c)(4) of this section. (i) Simple leachate collec tion. This sy stem consists of a gravit y flow drainfield installed above the waste disposal unit liner. This design is recommended for use when semi

- solid or leachable solid wastes are placed in a lined pit excavated into a relativel y thick, unsaturated, ho mogenous lay er of low permeabilit y soil. (ii) Compound leachate collection. This sy stem consists of a gravity flow drainfield installed above the waste disposal unit liner and above a secondary installed liner. This design is recommended for use when semi

- liquid or leachable solid wastes are placed in a lined pit excavated into relativel y permeable soil. (iii) Suction ly simeters. This sy stem consists of a network of porous ceramic cups connected by hoses/tubing to a vacuum pump. The porous ceramic cups or suction ly simeters are installed along the sides and under the bottom of the waste disposal unit liner. This type of s ys tem works best when installed in a relatively permeable unsaturated soil immediately adjacent to the bottom and/or sides of the disposa l facility

. (8) Chemical waste landfill operations. (i) PCBs and PCB Items shall be placed in a landfill in a manner that will prevent damage to containers or articles. Other wastes placed in the landfill that are not chemicall y compatible with PCBs and P CB Items including organic solvents shall be segregated from the PCBs throughout the waste handling and disposal process.(ii) An operation plan shall be developed and submitted to the Regional Administrator for

approval as required in paragraph (c) of th is section. This plan shall include detailed explanations of the procedures to be used for recordkeeping, surface water handling procedures, excavation and backfilling, waste segregation burial coordinates, vehicle and equipment movement, use of roadway s, leachate collection sy stems, sampling and monitoring procedures, monitoring wells, environmental emergency contingency plans, and securit y measures to protect against vandalism and unauthorized waste placements. EPA guidelines entitled “Thermal Processing and Land Disposal of Solid Waste” (39 FR 29337, Aug. 14, 1974) are a useful reference in preparation of this plan. I f the facility

is to be used to dispose of liquid wastes containing between 50 ppm and 500 ppm PCB, the operations plan must include procedures to determine that liquid PCBs to be disposed of at the landfill do not exceed 500 ppm PCB and measures to prevent the migration of PCBs from the landfill. Bulk liquids not exceeding 500 ppm PCBs may be disposed of provided such waste is pretreated and/ or stabilized (e.g., chemically fixed, evaporated, mixed with dry inert absorbant) to reduce its liquid content or increase its solid content so that a non

- flowing consistency

is achieved to eliminate the presence of free liquids prior to final disposal in a landfill. PCB Container of liquid PCBs with a concentration between 50 and 500 ppm PCB may be disposed of if each container is surrounded b y an amount of inert sorbant material capable of absorbing all of the liquid contents of the container. (iii) Ign itable wastes shall not be disposed of in chemical waste landfills. L iquid ignitable wastes are wastes that have a flash point less than 60 degrees C (140 degrees F) as determined b y the following method or an equivalent method: Flash point of liquids shal l be determined b y a Pensky

- Martens Closed Cup Tester, using the protocol specified in ASTM D 93

– 90, or the Setaflash Closed Tester using the protocol specified in ASTM Standard D

– 3278

– 89. (iv) Records shall be maintained for all PCB disposal operations and shall include information on the PCB concentration in liquid wastes and the three dimensional burial coordinates for PCBs and PCB Items. Additional records shall be developed and maintained as required in §761.180. (9) Supporting facilities. (i) A six foot woven mesh fence, wall, or similar device shall be placed around the site to prevent unauthorized persons and animals from entering. (ii) Roads shall be maintained to and within the site which are adequate to support the operation and maintenance of the site without causing safet y or nuisance problems or hazardous conditions. (iii) The site shall be operated and maintained in a manner to prevent safety problems or hazardous conditions resulting from spilled liquids and windblown materials. (c) Appro val of chemical waste landfills. Prior to the disposal of an y PCBs and PCB Items in a chemical waste landfill, the owner or operator of the landfill shall receive written approval of the Agency Regional Administrator for the Region in which the landfill is located.

—PCB Spill Cleanup Policy
Source: 52 FR 1 0705, Apr. 2, 1987, unless otherwise noted. § 761.120 Scope. (a) General. This policy

establishes criteria EPA will use to determine the adequacy of the cleanup of spills resulting from the release of materials containing PCBs at concentrations of 50 p pm or greater. The policy applies to spills which occur after May 4, 1987. (1) Existing spills (spills which occurred prior to May 4, 1987, are excluded from the scope of this policy

for two reasons:(i) For old spills which have alread y been discovered, this policy is not intended to require additional cleanup where a part y has alread y cleaned a spill in accordance with requirements imposed by

EPA through its regional offices, nor is this policy intended to interfere with ongoing litigation of enforcement actions which bring into issue PCB spills cleanup. (ii) EPA recognizes that old spills which are discovered after the effective date of this policy will require site

- by

- site evaluation because of the likelihood that the site involves more pervasive PCB contamination than fresh spills and because old spills are generally more difficult to clean up than fresh spills (particularl y on porous surfaces such as concrete). Therefore, spills which occurred before the effective date of this policy are to be decont aminated to requirements established at the discretion of EPA, usually through its regional offices. (2) EPA expects most PCB spills subject to the TSCA PCB regulations to conform to the ty pical spill situations considered in developing this policy . This policy does, however, exclude from application of the final numerical cleanup standards certain spill situations from its scope: Spills directly into surface waters, drinking water, sewers, grazing lands, and vegetable gardens. These ty pes of spills are subject to final cleanup standards to be established at the discretion of the regional office. These spills are, however, subject to the immediate notification requirements and measures to minimize further environmental contamination. (3) For all other spil ls, EPA generall y expects the decontamination standards of this policy to apply . Occasionally , some small percentage of spills covered by this policy

may warrant more stringent cleanup requirements because of additional routes of exposure or significantl y greater exposures than those assumed in developing the final cleanup standards of this policy . While the EPA regional offices have the authorit y to require additional cleanup in these circumstances, the Regional Administrator must first make a finding base d on the specific facts of a spill that additional cleanup must occur to prevent unreasonable risk. In addition, before a final decision is made to require additional cleanup, the Regional Administrator must notify the Director, Office of Pollution Prevent ion and Toxics at Headquarters of his/her finding and the basis for the finding. (4) There may

also be exceptional spill situations that requires less stringent cleanup or a different approach to cleanup because of factors associated with the particular s pill. These factors may mitigate expected exposures and risks or make cleanup to these requirements impracticable. (b) Spills that may

require more stringent cleanup levels. For spills within the scope of this policy , EPA generall y retains, under §761.135 , the authority to require additional cleanup upon finding that, despite good faith efforts by the responsible party , the numerical decontamination levels in the policy

have not been met. In addition, EPA foresees the possibility of exceptional spill situations in which site

- specific risk factors may warrant additional cleanup to more stringent numerical decontamination levels than are required by the policy . In these situations, the Regional Administrator has the authorit y to require cleanup to levels lowe r than those included in this policy

upon finding that further cleanup must occur to prevent unreasonable risk. The Regional Administrator will consult with the Director, Office of Pollution Prevention and Toxics, prior to making such a finding.(1) For e xample, site

- specific characteristics, such as short depth to ground water, t ype of soil, or

the presence of a shallow well, may pose exceptionally

high potential for ground water contamination by

PCBs remaining after cleanup to the standards specified in this policy . Spills that pose such a high degree of potential for ground water contamination have not been excluded from the policy

under paragraph (d) of this section because the presence of such potential may not be readil y apparent. EPA feels that autom atically excluding such spills from the scope of the policy could result in the delay

of cleanup

— a particularl y undesirable outcome if potential ground water contamination is, in fact, a significant concern. (2) In those situations, the Regional Administr ator may require cleanup in addition to that required under §761.125 (b) and (c). However, the Regional Administrator must first make a finding, based on the specific facts of a spill, that additional cleanup is necessary to prevent unreasonable risk. In a ddition, before making a final decision on additional cleanup, the Regional Administrator must notify the Director of the Office of Pollution Prevention and Toxics of his finding and the basis for the finding. (c) Flexibility

to allow less stringent or al ternative requirements. EPA retains the flexibility to allow less stringent or alternative decontamination measures based upon site

- specific considerations. EPA will exercise this flexibility if the responsible part y demonstrates that cleanup to the numeri cal decontamination levels is clearl y unwarranted because of risk

mitigating factors, that compliance with the procedural requirements or numerical standards in the policy is impracticable at a particular site, or that site

- specific characteristics make th e costs of cleanup prohibitive. The Regional Administrator will notify the Director of OPPT of any decision and the basis for the decision to allow less stringent cleanup. The purpose of this notification is to enable the Director of OPPT to ensure consist ency of spill cleanup standards under special circumstances across the regions. (d) Excluded spills. (1) Although the spill situations in paragraphs (d)(2) (i) through (vi) of this section are excluded from the automatic application of final decontaminati on standards under §761.125 (b) and (c), the general requirements under §761.125(a) do appl y t o these spills. In addition, all of these excluded situations require practicable, immediate actions to contain the area of contamination. While these situations may not alway s require more stringent cleanup measures, the Agency

is excluding these scenarios because they will alway s involve significant factors that may

not be adequatel y addressed b y cleanup standards based upon typical spill characteristics. (2) Fo r the spill situations in paragraphs (d)(2)(i) through (vi) of this section, the responsible party shall decontaminate the spill in accordance with site

- specific requirements established by the EPA regional offices. (i) Spills that result in the direct co ntamination of surface waters (surface waters include, but are not limited to, “waters of the United States” as defined in part 122 of this chapter, ponds, lagoons, wetlands, and storage reservoirs). (ii) Spills that result in the direct contamination of sewers or sewage treatment sy stems.(iii) Spills that result in the direct contamination of an y private or public drinking water sources

or distribution sy stems. (iv) Spills which migrate to and contaminate surface waters, sewers, or drinking water suppl ies before cleanup has been completed in accordance with this policy

. (v) Spills that contaminate animal grazing lands. (vi) Spills that contaminate vegetable gradens. (e) Relationship of policy to other statutes. (1) This policy does not affect cleanup standards or requirements for the reporting of spills imposed, or to be imposed, under other Federal statutory authorities, including but not limited to, the Clean Water Act (CWA), the Resource Conservation and Recovery

Act (RCRA), and the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA) as amended b y the Superfund Amendments and Reauthorization Act (SARA). Where more than one requirement applies, the stricter standard must be met. (2) The Agency

recognizes that the exis tence of this policy will inevitably

result in attempts to apply the standards to situations within the scope of other statutory authorities. However, other statutes require the Agency to consider different or alternative factors in determining appropriate corrective actions. In addition, the ty pes and magnitudes of exposures associated with sites requiring corrective action under other statutes often involve important differences from those expected of the t ypical, electrical equipment

- ty pe spills consider ed in developing this policy

. Thus, cleanups under other statutes, such as RCRA corrective actions or remedial and response actions under SARA may result in different outcomes. § 761.123 Definitions. For purposes of this policy, certain words and phras es are used to denote specific materials, procedures, or circumstances. The following definitions are provided for purposes of clarity and are not to be taken as exhaustive lists of situations and materials covered b y the policy. Double wash/rinse means a minimum requirement to cleanse solid surfaces (both impervious and nonimpervious) two times with an appropriate solvent or other material in which PCBs are at least 5 percent soluble (by weight). A volume of PCB

- free fluid sufficient to cover the contamin ated surface completely must be used in each wash/rinse. The wash/rinse requirement does not mean the mere spreading of solvent or other fluid over the surface, nor does the requirement mean a once

- over wipe with a soaked cloth. Precautions must be taken t o contain any runoff resulting from the cleansing and to dispose properl y of wastes generated during the cleansing. High

- concentration PCBs means PCBs that contain 500 ppm or greater PCBs, or those materials which EPA requires to be assumed to contain 500 ppm or greater PCBs in the absence of testing. High

- contact industrial surface means a surface in an industrial setting which is repeatedl y touched, often for relatively long periods of time. Manned machinery and control panels areexamples of high

- conta ct industrial surfaces. High

- contact industrial surfaces are generally of impervious solid material. Examples of low

- contact industrial surfaces include ceilings, walls, floors, roofs, roadway s and sidewalks in the industrial area, utility poles, unmanned machinery , concrete pads beneath electrical equipment, curbing, exterior structural building components, indoor vaults, and pipes. High

- contact residential/commercial surface means a surface in a residential/commercial area which is repeatedl y touched, oft en for relativel y l ong periods of time. Doors, wall areas below 6 feet in height, uncovered flooring, windowsills, fencing, bannisters, stairs, automobiles, and children's play

areas such as outdoor patios and sidewalks are examples of high

- contact residential/commercial surfaces. Examples of low

- contact residential/commercial surfaces include interior ceilings, interior wall areas above 6 feet in height, roofs, asphalt roadway s, concrete roadway s, wooden utility poles, unmanned machinery , concrete pads ben eath electrical equipment, curbing, exterior structural building components (e.g., aluminum/vinyl siding, cinder block, asphalt tiles), and pipes. Impervious solid surfaces means solid surfaces which are nonporous and thus unlikely to absorb spilled PCBs within the short period of time required for cleanup of spills under this policy. Impervious solid surfaces include, but are not limited to, metals, glass, aluminum siding, and enameled or laminated surfaces.
Low

- concentration PCBs means PCBs that are tes ted and found to contain less than 500 ppm PCBs, or those PCB

- containing materials which EPA requires to be assumed to be at concentrations below 500 ppm (i.e., untested mineral oil dielectric fluid). Nonimpervious solid surfaces means solid surfaces whic h are porous and are more likel y to absorb spilled PCBs prior to completion of the cleanup requirements prescribed in this policy

. Nonimpervious solid surfaces include, but are not limited to, wood, concrete, asphalt, and plasterboard. Nonrestricted acces s areas means an y area other than restricted access, outdoor electrical substations, and other restricted access locations, as defined in this section. In addition to residential/commercial areas, these areas include unrestricted access rural areas (areas of low density development and population where access is uncontrolled by either man

- made barriers or naturally occurring barriers, such as rough terrain, mountains, or cliffs). Other restricted access (nonsubstation) locations means areas other than elec trical substations that are at least 0.1 kilometer (km) from a residential/commercial area and limited by man - made barriers (e.g., fences and walls) to substantially limited by

naturally occurring barriers such as mountains, cliffs, or rough terrain. These areas generall y include industrial facilities and extremely remote rural locations. (Areas where access is restricted but are less than 0.1 km from a residential/commercial area are considered to be residential/commercial areas.) Outdoor electrical subst ations means outdoor, fenced

- off, and restricted access areas used in the transmission and/or distribution of electrical power Outdoor electrical substations restrict public access by being fenced or walled off as defined under §761.30(l)(1)(ii). For purpo ses of this TSCA policy , outdoor electrical substations are defined as being located at least 0.1 km from aresidential/commercial area. Outdoor fenced

- off and restricted access areas used in the

transmission and/or distribution of electrical power which are located less than 0.1. km from a residential/commercial area are considered to be residential/commercial areas. PCBs means poly chlorinated biphenyls as defined under §761.3. As specified under §761.1(b), no requirements may

be avoided through dilution of the PCB concentration. Requirements and standards means: (1) “Requirements” as used in this policy refers to both the procedural responses and numerical decontamination levels set forth in this policy as constituting adequate cleanup of PCBs. (2) “Standards” refers to the numerical decontamination levels set forth in this policy

. Residential/commercial areas means those areas where people live or reside, or where people work in other than manufacturing or farming industries. Residential areas include housing and the propert y on which housing is located, as well as playgrounds, roadways, sidewalks, parks, and other similar areas within a residential community . Commercial areas are ty picall y accessible to both members of the general public and employ ees and include public assembl y properties, institutional properties, stores, office buildings, and transportation centers. Responsible party

means the owner of the PCB equipment, facility , or other source of PCBs or his/her designated agent (e.g., a faci lity manager or foreman). Soil means all vegetation, soils and other ground media, including but not limited to, sand, grass, gravel, and o ys ter shells. It does not include concrete and asphalt. Spill means both intentional and unintentional spills, leak s, and other uncontrolled discharges where the release results in any quantity of PCBs running off or about to run off the external surface of the equipment or other PCB source, as well as the contamination resulting from those releases. This policy

applie s to spills of 50 ppm or greater PCBs. The concentration of PCBs spilled is determined by

the PCB concentration in the material spilled as opposed to the concentration of PCBs in the material onto which the PCBs were spilled. Where a spill of untested mine ral oil occurs, the oil is presumed to contain greater than 50 ppm, but less than 500 ppm PCBs and is subject to the relevant requirements of this policy

. Spill area means the area of soil on which visible traces of the spill can be observed plus a buffer zone of 1 foot bey ond the visible traces. An y surface or object (e.g., concrete sidewalk or automobile) within the visible traces area or on which visible traces of the spilled material are observed is included in the spill area. This area represents the minimum area assumed to be contaminated b y PCBs in the absence of precleanup sampling data and is thus the minimum area which must be cleaned. Spill boundaries means the actual area of contamination as determined b y postcleanup verification sampling or by precleanup sampling to determine actual spill boundaries. EPA can require additional cleanup when necessary to decontaminate all areas within the spill boundariesto the levels required in this policy (e.g., additional cleanup will be required if postcleanup sampling indicates that the area decontaminated by the responsible part y, such as the spill area as defined in this section, did not encompass the actual boundaries of PCB contamination). Standard wipe test means, for spills of high

- concentration PCBs on solid surfaces, a cleanup to numerical surface standards and sampling b y a standard wipe test to verify that the numerical standards have been met. This definition constitutes the minimum requirements for an appropriate wipe testing protocol. A standar d

- size template (10 centimeters (cm) x 10 cm) will be used to delineate the area of cleanup; the wiping medium will be a gauze pad or glass wool of known size which has been saturated with hexane. It is important that the wipe be performed very quickl y aft er the hexane is exposed to air. EPA strongl y recommends that the gauze (or glass wool) be prepared with hexane in the laboratory and that the wiping medium be stored in sealed glass vials until it is used for the wipe test. Further, EPA requires the colle ction and testing of field blanks and replicates. [52 FR 10705, Apr. 2, 1987; 52 FR 23397, June 19, 1987] § 761.125 Requirements for PCB spill cleanup. (a) General. Unless expressly limited, the reporting, disposal, and precleanup sampling requirement s in paragraphs (a) (1) through (3) of this section apply to all spills of PCBs at concentrations of 50 ppm or greater which are subject to decontamination requirements under TSCA, including those spills listed under §761.120(b) which are excluded from the cleanup standards at paragraphs (b) and (c) of this section. (1) Reporting requirements. The reporting in paragraphs (a)(1) (i) through (iv) of this section is required in addition to applicable reporting requirements under the Clean Water Act (CWA) or the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA). For example, under the National Contingency Plan all spills involving 1 pound or more by weight of PCBs must currently be reported to the National Response Center (1

- 8 00

- 424

- 8802). The requirements in paragraphs (a)(1) (i) through (iv) of this section are designed to be consistent with existing reporting requirements to the extent possible so as to minimize reporting burdens on governments as well as the regulated community

. (i) Where a spill directl y contaminates surface water, sewers, or drinking water supplies, as discussed under §761.120(d), the responsible party shall notify

the appropriate EPA regional office (the Office of Prevention, Pesticides and Toxic Substan ces Branch) and obtain guidance for appropriate cleanup measures in the shortest possible time after discovery , but in no case later than 24 hours after discovery

. (ii) Where a spill directl y contaminates grazing lands or vegetable gardens, as discussed under §761.120(d), the responsible part y shall notify the appropriate EPA regional office (the Office of Prevention, Pesticides and Toxic Substances Branch) and proceed with the immediate requirements specified under paragraph (b) or (c) of this section, d epending on the source of the spill, in the shortest possible time after discovery , but in no case later than 24 hours after discovery

.(iii) Where a spill exceeds 10 pounds of PCBs by weight and is not addressed in paragraph (a)(1) (i) or (ii) of this se ction, the responsible party will notify

the appropriate EPA regional office (Pesticides and Toxic Substances Branch) and proceed to decontaminate the spill area in accordance with this TSCA policy in the shortest possible time after discovery , but in no c ase later than 24 hours after discovery

. (iv) Spills of 10 pounds or less, which are not addressed in paragraph (a)(1) (i) or (ii) of this section, must be cleaned up in accordance with this policy (in order to avoid EPA enforcement liability ), but notifi cation of EPA is not required. (2) Disposal of cleanup debris and materials. All concentrated soils, solvents, rags, and other materials resulting from the cleanup of PCBs under this policy shall be properly

stored, labeled, and disposed of in accordance with the provisions of subpart D of this part. (3) Determination of spill boundaries in the absence of visible traces. For spills where there are insufficient visible traces y et there is evidence of a leak or spill, the boundaries of the spill are to be d etermined b y using a statistically based sampling scheme. (b) Requirements for cleanup of low

- concentration spills which involve less than 1 pound of PCBs by weight (less than 270 gallons of untested mineral oil)

— (1) Decontamination requirements. Spills o f less than 270 gallons of untested mineral oil, low

- concentration PCBs, as defined under §761.123, which involve less than 1 pound of PCBs by weight (e.g., less than 270 gallons of untested mineral oil containing less than 500 ppm PCBs) shall be cleaned i n the following manner: (i) Solid surfaces must be double washed/rinsed (as defined under §761.123); except that all indoor, residential surfaces other than vault areas must be cleaned to 10 micrograms per 100 square centimeters (10  g/100 cm2) b y standar d commercial wipe tests. (ii) All soil within the spill area (i.e., visible traces of soil and a buffer of 1 lateral foot around the visible traces) must be excavated, and the ground be restored to its original configuration b y back

- filling with clean soi l (i.e., containing less than 1 ppm PCBs). (iii) Requirements of paragraphs (b)(1) (i) and (ii) of this section must be completed within 48 hours after the responsible part y was notified or became aware of the spill. (2) Effect of emergency

or adverse we ather. Completion of cleanup may be delay ed bey ond 48 hours in case of circumstances including but not limited to, civil emergency, adverse weather conditions, lack of access to the site, and emergency operating conditions. The occurrence of a spill on a w eekend or overtime costs are not acceptable reasons to delay response. Completion of cleanup may

be delay ed only

for the duration of the adverse conditions. If the adverse weather conditions, or time lapse due to other emergency , has left insufficient visi ble traces, the responsible part y must use a statistically based sampling scheme to determine the spill boundaries as required under paragraph (a)(3) of this section.(3) Records and certification. At the completion of cleanup, the responsible party shall document the cleanup with records and certification of decontamination. The records and certification must be maintained for a period of 5 y ears. The records and certification shall consist of the following: (i) Identification of the source of the spill (e.g., type of equipment). (ii) Estimated or actual date and time of the spill occurrence. (iii) The date and time cleanup was completed or terminated (if cleanup was delay ed by emergency

or adverse weather: the nature and duration of the delay). (iv) A brief description of the spill location. (v) Precleanup sampling data used to establish the spill boundaries if required because of insufficient visible traces, and a brief description of the sampling methodology used to establish the spill boundaries. (vi) A brief description of the solid surfaces cleaned and of the double wash/rinse method used. (vii) Approximate depth of soil excavation and the amount of soil removed. (viii) A certification statement signed b y the responsible party stating that the cleanup requirements have been met and that the information contained in the record is true to the best of his/her knowledge. (ix) While not required for compliance with this policy , the following information would be useful if maintained in the records: (A) Additional pre

- or post

- cleanup sampling. (B) The estimated cost of the cleanup b y man - hours, dollars, or both. (c) Requirements for cleanup of high

- concentration spills and low

- concentration spills involving 1 pound or more PCBs by weight (270 gall ons or more of untested mineral oil). Cleanup of low

concentration spills involving 1 lb or more PCBs by weight and of all spills of materials other than low

- concentration materials shall be considered complete if all of the immediate requirements, cleanup standards, sampling, and recordkeeping requirements of paragraphs (c) (1) through (5) of this section are met. (1) Immediate requirements. The four actions in paragraphs (c)(1) (i) through (iv) of this section must be taken as quickl y as possible and within no more than 24 hours (or within 48 hours for PCB Transformers) after the responsible part y was notified or became aware of the spill, except that actions described in paragraphs (c)(1) (ii) through (iv) of this section can be delay ed bey ond 24 hours i f circumstances (e.g., civil emergency , hurricane, tornado, or other similar adverse weather conditions, lack of access due to ph ys ical impossibility , or emergency operating conditions) so require for the duration of the adverse conditions. The occurrence of a spill on aweekend or overtime costs are not acceptable reasons to delay response. Owners of spilled PCBs

who have delay ed cleanup because of these t ypes of circumstances must keep records documenting the fact that circumstances precluded rapid respon se. (i) The responsible part y shall notify the EPA regional office and the NRC as required b y §761.125(a)(1) or b y other applicable statutes. (ii) The responsible part y shall effectively cordon off or otherwise delineate and restrict an area encompassing an y visible traces plus a 3

- foot buffer and place clearly visible signs advising persons to avoid the area to minimize the spread of contamination as well as the potential for human exposure. (iii) The responsible party shall record and document the area of visible contamination, noting the extent of the visible trace areas and the center of the visible trace area. If there are no visible traces, the responsible party shall record this fact and contact the regional office of the EPA for guidance in comple ting statistical sampling of the spill area to establish spill boundaries. (iv) The responsible party shall initiate cleanup of all visible traces of the fluid on hard surfaces and initiate removal of all visible traces of the spill on soil and other medi a, such as gravel, sand, oy ster shells, etc. (v) If there has been a delay in reaching the site and there are insufficient visible traces of PCBs remaining at the spill site, the responsible part y m ust estimate (based on the amount of material missing fro m the equipment or container) the area of the spill and immediately cordon off the area of suspect contamination. The responsible party must then utilize a statistically based sampling scheme to identify the boundaries of the spill area as soon as practica ble. (vi) Although this policy

requires certain immediate actions, as described in paragraphs (c)(1)(i) through (iv) of this section, EPA is not placing a time limit on completion of the cleanup effort since the time required for completion will vary from case to case. However, EPA expects that decontamination will be achieved promptly in all cases and will consider promptness of completion in determining whether the responsible part y made good faith efforts to clean up in accordance with this policy

. (2) Requirements for decontaminating spills in outdoor electrical substations. Spills which occur in outdoor electrical substations, as defined under §761.123, shall be decontaminated in accordance with paragraphs (c)(2) (i) and (ii) of this section. Conformance to the cleanup standards under paragraphs (c)(2) (i) and (ii) of this section shall be verified by post

- cleanup sampling as specified under §761.130. At such times as outdoor electrical substations are converted to another use, the spill site shall be cleaned up to the nonrestricted access requirements under paragraph (c)(4) of this section. (i) Contaminated solid surfaces (both impervious and non

- impervious) shall be cleaned to a PCB concentration of 100 micrograms (  g)/100 square centimeters (cm 2) ( as measured b y standard wipe tests).(ii) At the option of the responsible part y, soil contaminated by the spill will be cleaned either to

25 ppm PCBs by

weight, or to 50 ppm PCBs by weight provided that a label or notice is visibly placed in the area. Up on demonstration by the responsible party

that cleanup to 25 ppm or 50 ppm will jeopardize the integrit y of the electrical equipment at the substation, the EPA regional office may

establish an alternative cleanup method or level and place the responsible p arty on a reasonabl y timel y schedule for completion of cleanup. (3) Requirements for decontaminating spills in other restricted access areas. Spills which occur in restricted access locations other than outdoor electrical substations, as defined under §76 1.123, shall be decontaminated in accordance with paragraphs (c)(3) (i) through (v) of this section. Conformance to the cleanup standards in paragraphs (c)(3) (i) through (v) of this section shall be verified b y postcleanup sampling as specified under §761 .130. At such times as restricted access areas other than outdoor electrical substations are converted to another use, the spill site shall be cleaned up to the nonrestricted access area requirements of paragraph (c)(4) of this section. (i) High

- contact s olid surfaces, as defined under §761.163 shall be cleaned to 10  g/100 cm 2 (as measured b y standard wipe tests). (ii) L ow - contact, indoor, impervious solid surfaces will be decontaminated to 10  g/100 cm 2. (iii) At the option of the responsible part y , low

- contact, indoor, nonimpervious surfaces will be cleaned either to 10  g/100 cm 2 or to 100  g/100 cm 2 and encapsulated. The Regional Administrator, however, retains the authorit y to disallow the encapsulation option for a particular spill situation upon finding that the uncertainties associated with that option pose special concerns at that site. That is, the Regional Administrator would not permit encapsulation if he/she determined that if the encapsulation failed the failure would create an imminent hazard at the site. (iv) L ow - contact, outdoor surfaces (both impervious and nonimpervious) shall be cleaned to 100  g/100 cm 2. (v) Soil contaminated b y the spill will be cleaned to 25 ppm PCBs by weight. (4) Requirements for decontaminating spills in nonrestricted access areas. Spills which occur in nonrestricted access locations, as defined under §761.123, shall be decontaminated in accordance with paragraphs (c)(4) (i) through (v) of this section. Conformance to the cleanup standards at paragraphs ( c)(4) (i) through (v) of this section shall be verified by postcleanup sampling as specified under §761.130. (i) Furnishings, to ys , and other easil y replaceable household items shall be disposed of in accordance with the provisions of subpart D of this part and replaced b y the responsible party. (ii) Indoor solid surfaces and high

- contact outdoor solid surfaces, defined as high contact residential/commercial surfaces under §761.123, shall be cleaned to 10  g/100 cm 2 (as measured b y standard wipe tests).(iii) Indoor vault areas and low

- contact, outdoor, impervious solid surfaces shall be

decontaminated to 10  g/100 cm 2. (iv) At the option of the responsible part y, low

- contact, outdoor, nonimpervious solid surfaces shall be either cleaned to 10  g/100 cm 2 or cleaned to 100  g/100 cm 2 and encapsulated. The Regional Administrator, however, retains the authority to disallow the encapsulation option for a particular spill situation upon finding that the uncertainties associated with that option pose spe cial concerns at that site. That is, the Regional Administrator would not permit encapsulation if he/she determined that if the encapsulation failed the failure would create an imminent hazard at the site. (v) Soil contaminated b y the spill will be decontaminated to 10 ppm PCBs by weight provided that soil is excavated to a minimum depth of 10 inches. The excavated soil will be replaced with clean soil, i.e., containing less than 1 ppm PCBs, and the spill site will be restored (e.g., replacement of turf). (5) Records. The responsible party shall document the cleanup with records of decontamination. The records must be maintained for a period of 5 y ears. The records and certification shall consist of the following: (i) Identification of the source of the spill, e.g., t ype of equipment. (ii) Estimated or actual date and time of the spill occurrence. (iii) The date and time cleanup was completed or terminated (if cleanup was delay ed by emergency

or adverse weather: the nature and duration of the delay). (iv) A brief description of the spill location and the nature of the materials contaminated. This information should include whether the spill occurred in an outdoor electrical substation, other restricted access location, or in a nonrestricted access area. (v) Precleanup sampling data used to establish the spill boundaries if required because of insufficient visible traces and a brief description of the sampling methodology used to establish the spill boundaries. (vi) A brief description of the solid surfaces cleaned. (vii) Approximate depth of soil excavation and the amount of soil removed. (viii) Postcleanup verification sampling data and, if not otherwise apparent from the documentation, a brief description of the sampling methodology and anal yt i cal technique used. (ix) While not required for compliance with this policy , information on the estimated cost of cleanup (b y man - hours, dollars, or both) would be useful if maintained in the records. [52 FR 10705, Apr. 2, 1987, as amended at 53 FR 40884 , Oct. 19, 1988; 63 FR 35461, June 29,1998]

§ 761.130 Sampling requirements. Postcleanup sampling is required to verify the level of cleanup under §761.125(c) (2) through (4). The responsible party may use any statistically

valid, reproducible, sampli ng scheme (either random samples or grid samples) provided that the requirements of paragraphs (a) and (b) of this section are satisfied. (a) The sampling area is the greater of (1) an area equal to the area cleaned plus an additional 1

- foot boundary , or (2) an area 20 percent larger than the original area of contamination. (b) The sampling scheme must ensure 95 percent confidence against false positives. (c) The number of samples must be sufficient to ensure that areas of contamination of a radius of 2 feet or more within the sampling area will be detected, except that the minimum number of samples is 3 and the maximum number of samples is 40. (d) The sampling scheme must include calculation for expected variability due to anal yt ical error. (e) EPA rec ommends the use of a sampling scheme developed b y the Midwest Research Institute (MRI) for use in EPA enforcement inspections: “Verification of PCB Spill Cleanup by Sampling and Anal ys is.” Guidance for the use of this sampling scheme is available in the MR I report “Field Manual for Grid Sampling of PCB Spill Sites to Verify Cleanup.” Both the MRIsampling scheme and the guidance document are available from the Director, Environmental Assistance Division (7408), Office of Pollution Prevention and Toxics, U.S . Environmental Protection Agency , Room E

– 543B, 1200 Pennsylvania Ave., NW., Washington, DC 20460, Telephone: (202) 554

– 1404, TDD: (202) 544

– 0551. The major advantage of this sampling scheme is that it is designed to characterize the degree of contaminatio n within the entire sampling area with a high degree of confidence while using fewer samples than an y other grid or random sampling scheme. This sampling scheme also allows some sites to be characterized on the basis of composite samples. (f) EPA may , at its discretion, take samples from any spill site. If EPA's sampling indicates that the remaining concentration level exceeds the required level, EPA will require further cleanup. For this purpose, the numerical level of cleanup required for spills cleaned in accordance with §761.125(b) is deemed to be the equivalent of numerical cleanup requirements required for cleanups under §761.125(c) (2) through (4). Using its best engineering judgment, EPA may sample a statistically

valid random or grid sampling techn ique, or both. When using engineering judgment or random “grab” samples, EPA will take into account that there are limits on the power of a grab sample to dispute statistically based sampling of the ty pe required of the responsible part y. EPA headquarters will provide guidance to the EPA regions on the degree of certaint y associated with various grab sample results. [52 FR 10705, Apr. 2, 1987, as amended at 60 FR 34465, July 3, 1995]§ 761.135 Effect of compliance with this policy and enforcement.

(a) Although a spill of material containing 50 ppm or greater PCBs is considered improper PCB disposal, this policy

establishes requirements that EPA considers to be adequate cleanup of the spilled PCBs. Cleanup in accordance with this policy means compliance with the procedural as well as the numerical requirements of this policy . Compliance with this policy creates a presumption against both enforcement action for penalties and the need for further cleanup under TSCA. The Agency

reserves the right, however, t o initiate appropriate action to compel cleanup where, upon review of the records of cleanup or EPA sampling following cleanup, EPA finds that the decontamination levels in the policy have not been achieved. The Agency also reserves the right to seek penal ties where the Agency believes that the responsible party has not made a good faith effort to comply with all provisions of this policy , such as prompt notification of EPA of a spill, recordkeeping, etc. (b) EPA's exercise of enforcement discretion does n ot preclude enforcement action under other provisions of TSCA or any other Federal statute. This includes, even in cases where the numerical decontamination levels set forth in this policy have been met, civil or criminal action for penalties where EPA bel ieves the spill to have been the result of gross negligence or knowing violation.

— general requirements. (a) A generator who relinquishes control over PCB wastes b y transporting, or offering for transport b y his own vehicle or b y a vehicle owned by another person, PCB waste fo r commercial off

- site storage or off

- site disposal shall prepare a manifest on EPA Form 8700

–22, and if necessary , a continuation sheet. The generator shall specify : (1) For each bulk load of PCBs, the identity of the PCB waste, the earliest date of remov al from service for disposal, and the weight in kilograms of the PCB waste. (2) For each PCB Article Container or PCB Container, the unique identifying number, ty pe of PCB waste (e.g., soil, debris, small capacitors), earliest date of removal from service for disposal, and weight in kilograms of the PCB waste contained. (3) For each PCB Article not in a PCB Container or PCB Article Container, the serial number if available, or other identification if there is no serial number, the date of removal from ser vice for disposal, and weight in kilograms of the PCB waste in each PCB Article. (b) EPA does not maintain supplies of printed copies of Form 8700

–22 for public use, although printed copies of the manifest may be available from State offices. Camera

- read y copies of the form are available for printing purposes from State offices, EPA Regional Offices, and EPA Headquarters. (c) If the State to which the shipment is manifested (i.e., consignment State) supplies the manifest and requires its use, then the gene rator must use that manifest. (d) If the consignment State does not supply the manifest, but the State in which the generator is located (i.e., generator State) supplies the manifest and requires its use, then the generator must use that State's manifest. (e) If both the consignment State and the generator State supply manifests and require their use, the generator must use the consignment State's manifest. (f) If neither the generator State nor the consignment State supplies the manifest, the generator may obtain the manifest from any source. (g) A generator shall designate on the manifest one off

- site commercial storage or disposal facility approved under this part for the commercial storage or disposal of the PCBs and PCB Items described on the manifest.(h) If the transporter is unable to deliver the PCB waste to the designated disposer or commercial

storer, the transporter must contact the generator of the PCB waste for instructions. The generator shall either d esignate another approved disposer or commercial storer, or instruct the transporter to return the PCB waste back to the generator. (i) The manifest which accompanies the PCB waste shall consist of at a minimum the number of copies required to provide the generator, the initial transporter, each subsequent transporter, and the owner or operator of the designated commercial storage or disposal facility with one legible copy each for their records, and one additional copy to be returned to the generator by the owner or operator of the first designated commercial storage or disposal facility. (j) The requirements of this section apply onl y to PCB wastes as defined in §761.3. This includes PCB wastes with PCB concentrations below 50 ppm where the PCB concentration below 50 ppm was the result of dilution; these PCB wastes are required under §761.1(b) to be managed as if they contained PCB concentrations of 50 ppm and above. An example of such a PCB waste is spill cleanup material containing <50 ppm PCBs when the spill involved material containing PCBs at a concentration of  50 ppm . However, there is no manifest requirement for material currentl y below 50 ppm which derives from pre

- April 18, 1978, spills of any concentration, pre

July 2, 1979, spills of < 500 pp m PCBs, or materials decontaminated in accordance with §761.79. [54 FR 52752, Dec. 21, 1989, as amended at 63 FR 35461, June 29, 1998] § 761.208 Use of the manifest. (a)(1) The generator of PCB waste shall: (i) Sign the manifest certification by hand

—Determining a PCB Concentration for Purposes of Abandonment or Disposal of Natural Gas Pipeline: Selecting Sample Sites, Co llecting Surface Samples, and Anal yz ing Standard PCB Wipe Samples Source: 63 FR 35462, June 29, 1998, unless otherwise noted. § 761.240 Scope and definitions. (a) Use these procedures to select surface sampling sites for natural gas pipe to determine its PCB surface concentration for abandonment

- in

- place or removal and disposal off

- site in accordance with §761.60(b)(5). (b) “Pipe segment” means a length of natural gas pipe that has been removed from the pipeline sy stem to be disposed of or r eused, and that is usually approximately

12.2 meters (40 feet) or shorter in length. Pipe segments are usuall y linear. (c) “Pipeline section” means a length of natural gas pipe that has been cut or otherwise separated from the active pipeline, usually for purposes of abandonment, and that is usually longer than 12.2 meters in length. Pipeline sections may be branched.§ 761.243 Standard wipe sample method and size.

(a) Collect a surface sample from a natural gas pipe segment or pipeline section using a standard wipe test as defined in §761.123. Detailed guidance for the entire wipe sampling process appears in the document entitled “Wipe Sampling and Double Wash/Rinse Cleanup as Recommended b y the Environmental Protection Agency PCB Spill Cleanup Policy , ” dated June 23, 1987 and revised on April 18, 1991. This document is available from the TSCA Assistance Information Service, Environmental Protection Agency , 1200 Pennsylvania Ave., NW., Washington, DC 20460. (b) Collect a surface sample from a minimum s urface area of 100 cm2 at each sampling site selected. The EPA Regional Administrator may approve, in writing, requests to collect a sample from smaller surface areas, when <100 cm2 of surface eligible for sampling is present; e.g., when sampling a small d iameter pipe, a small valve, or a small regulator. When smaller surfaces are sampled, convert the measurement to the equivalent measurement for 100 cm2 for purposes of comparison to standards based on 100 cm2. § 761.247 Sample site selection for pipe se gment removal. (a) General. (1) Select the pipe segments to be sampled by following the directions in paragraph (b) of this section. (2) Locate the proper position along the length of the pipe segment that y ou have selected for sampling, b y following the directions in paragraph (c) of this section. (3) Select the proper sampling position around the circumference of the pipe segment that you have selected for sampling, b y following the directions in paragraph (d) of this section. (4) Prior to removing pi pe from the ground or lifting the pipe from its location during former operations, mark the top side of the pipe. (5) Do not sample if there are free

- flowing liquids in the pipe segment. Free

- flowing liquids must be removed prior to sampling. (b) Selectin g pipe segments to sample. Select the pipe segment(s) that you will sample from a length of pipe or group of pipe segments, as follows: (1) Do not sample a pipe segment that is longer than 12.2 meters (40 feet). If a segment is longer than 12.2 meters in length, cut the segment so that all resulting segments are 12.2 meters or less in length. (2) Determine which pipe segments to sample as follows: (i) When a length of pipe having seven or fewer segments is removed for purposes of disposal, sample each pipe segment. (ii) When removing a length of pipe having multiple contiguous segments less than 3 miles intotal length, take samples from a total of seven segments.

(A) Sample the first and last segments removed. (B) Select the five additional segments according to one of the two following procedures: (1) Assign all segments a unique sequential number. Then select five numbers using a random number table or random number generator. If the random number generator or random number table produces either the first pipe segment, the last pipe segment, or any previously

selected segment, select another random number until there are seven different numbers, each corresponding to a different pipe segment. (2) Divide the total number of segments b y six. Round the resulting quotient off to the nearest whole number. The resulting number is the interval between the segments y ou will sample. For example, cut a 2.9 mile length of pipeline into 383 segments of approximately 40 feet each. Sample the first (number 1) an d last (number 383) segments. To determine which additional five segments to sample, divide the total number of segments, 383, b y 6. Round up the resulting number in this example, 63.8, to the next whole number, 64. Add 64 to the number of each preceding p ipe segment five separate times to select five additional pipe segments for sampling. In this example, the first pipe segment has the number 1, add 64 to 1 to select segment 65. Next, add 64 to 65 to select segment 129. Continue in this fashion to select a ll seven segments: 1, 65, 129, 193, 257, 321, and 383. (iii) When removing a length of pipe having multiple contiguous segments more than 3 miles in total length for purposes of disposal, take samples of each segment that is 1/2 mile distant from the segm ent previousl y s ampled. Sample a minimum of seven segments. (c) Selecting the sampling position

— length. Select the sampling position along the length of the pipe segment, as follows: (1) Take samples at the end upstream of the former gas flow of each segment removed. (2) If the pipe segment is cut with a torch or other high temperature heat source, take the sample at least 15 cm (6 inches) inside the cut end of the pipe segment. (3) If the pipe segment is cut with a saw or other mechanical device, take the sample at least 2 cm (1 inch) inside the end of the pipe segment. (4) If the sample site location selected in the procedure at paragraph (c)(2) or (c)(3) of this section is a porous surface (for example, there is significant corrosion so that the wipe material will be shredded), then move the sample site further inside the pipe segment (away from the end of the pipe or pipe segment) until there is no such porous surface. For purposes of this subpart, natural gas pipe with a thin porous corrosion preventive coating is a non

- porous surface. (5) If there is not a non

- porous surface accessible by paragraphs (c)(2) and (c)(3) of this section, use one of the following three options:(i) Sample the downstream end of the pipe segment using the same sample sit e location

procedure as for the upstream end. (ii) Select another pipe segment using the random selection procedure described in paragraph (b) of this section. (iii) If there is no other pipe segment in the population to be sampled and both ends of a pipe segment have porous surfaces at all possible sample collection sites, then assume that the pipe segment contains  50 ppm PCB but <500 ppm PCB. (d) Selecting the sample position

— circumference. Based on the mark on the top of the pipe segment made prior to removing pipe from the ground or lifting the pipe from its location during former operations, sample the inside center of the bottom of the pipe being sampled . Make sure the sample is centered on the bottom of the pipe segment; that is, sample an equal area on both sides of the middle of the bottom of the pipe segment for the entire length of the sample.

This procedure is for the sample site selection for a pipeline section to be abandoned, in accordance with §761.60(b)(5)(i)(B). (a) General. (1) Select sample collection sites in the pipeline section(s) b y following the directions in paragraph (b) of this section. (2) Select the proper sampling position along the pipe by following the directions in §761.247 (c) and (d). (3) Assure, b y visual inspection, the absence of fr ee - flowing liquids in the pipe by affirming no liquids at all liquid collection points and all ends of the pipeline section to be abandoned. (b) Selection sample collection sites. At a minimum, sample all ends of all pipeline sections to be abandoned in p lace. (1) If the pipeline section to be abandoned is between the pressure side of one compressor station and the suction side of the next compressor station downstream of the former gas flow, at a minimum, sample all ends of the abandoned pipe. (2) If th e pipeline section to be abandoned is longer than the distance between the pressure side of one compressor station and the suction side of the next compressor station downstream of the former gas flow, divide the pipeline section, for purposes of sampling, into smaller pipeline sections no longer than the distance from the pressure side of one compressor station to the suction side of the next compressor station downstream of the former gas flow. Consider each of the smaller sections to be a separate abando nment and sample each one, at a minimum, at allends.

(3) Use the following procedure to locate representative sample collection sites in pipeline sections at points other than the suction and pressure side of compressor stations, or the ends of the pipel ine section to be abandoned. (i) First, assign a unique identifying sequential number to each kilometer or fraction of a kilometer length of pipe within the entire pipeline section. (ii) Use a random number table or a random number generator to select each representative sample collection site from a complete list of the sequential identification numbers. (iii) Samples may

be collected b y removing an y covering soil, cutting the pipe to gain access to the sampling location, and collecting the surface sa mple with the pipe in place, rather than completely

removing the pipeline sections to collect the surface sample. [63 FR 35462, June 29, 1998, as amended at 64 FR 33762, June 24, 1999] § 761.253 Chemical analy sis. (a) Extract PCBs from the standard wi pe sample collection medium and clean

(a) For purposes of removal for disposal of a pipe segment that has been sampled, the sample results for that segment determines its PCB sur face concentration. Determine the PCB surface concentration of a segment which was not sampled as follows: (1) If the unsampled pipe segment is between two pipe segments which have been sampled, assume that the unsampled segment has the same PCB surface c oncentration as the nearest sampled pipe segment. (2) If an unsampled pipe segment is equidistant between two pipe segments which have been sampled, assume the PCB surface concentration of the unsampled segment to be the arithmetic mean of the PCB surface concentrations measured in the two equidistant, sampled, pipe segments. (b) For purposes of abandonment of a pipeline section, assume that the PCB surface concentration for an entire pipeline section is the arithmetic mean of the PCB surfaceconcentratio ns measured at the ends of the pipeline section.

— Sampling to Verify Completion of Self

- Implementing Cleanup and On

- Site Disposal of Bulk PCB Remediation Waste and Porous Surfaces in Accordance with §761.61(a)(6)Source: 63 FR 35465, June 29, 1998, unless o therwise noted.

§ 761.280 Application and scope. Follow the procedures in this subpart when sampling to verify completion of the cleanup for self

implementing, on

- site disposal of bulk PCB remediation waste and porous surfaces consistent with the level s of §761.61(a)(4)(i) and (iii). The objective of this subpart is not to search for new contamination. Confirmation of compliance with the cleanup levels in §761.61(a)(4) is only verifiable for the area sampled in accordance with this subpart. Do not make conclusions or extrapolations about PCB concentrations outside of the area which has been cleaned up and verified based on the results of this verification sampling. § 761.283 Determination of the number of samples to collect and sample collection locat ions. This section addresses how to determine the number of samples to collect and sample collection locations for bulk PCB remediation waste and porous surfaces destined to remain at a cleanup site after cleanup. (a) Minimum number of samples. (1) At each separate cleanup site at a PCB remediation waste location, take a minimum of three samples for each ty pe of bulk PCB remediation waste or porous surface at the cleanup site, regardless of the amount of each t ype of waste that is present. There is no u

pper limit to the number of samples required or allowed. (2) This is an example of how to calculate the minimum number of required samples at a PCB remediation waste location. There are three distinct cleanup sites at this example location: a loading dock , a transformer storage lot, and a disposal pit. The minimum number of samples to take appears in parentheses after each ty pe of waste for each cleanup site. The PCB remediation wastes present at the loading dock are concrete (three samples) and clay soil (three samples). The non - liquid PCB remediation wastes present at the transformer storage lot are oily soil (three samples), clay

soil (three samples) and gravel (three samples). The PCB remediation wastes present at the disposal pit are sand y soil (three samples), clay soil (three samples), oily soil (three samples), industrial sludge (three samples), and gravel (three samples). (b) Selection of sample locations

— general. (1)(i) Use a square

- based grid sy stem to overlay the entire area to be sampled. Orient the grid axes on a magnetic north

- south line centered in the area and an east

- west axis perpendicular to the magnetic north

- south axis also centered in the area. (ii) If the site is recleaned based on the results of cleanup verification conducted in acc ordance with §761.61(a)(6), follow the procedures in paragraph (b) of this section for locating sampling points after the recleaning, but reorient the grid axes established in paragraph (b)(1)(i) of this section by

moving the origin one meter in the direct ion of magnetic north and one meter in the direction east of magnetic north. (2) Mark out a series of sampling points 1.5 meters apart oriented to the grid axes. The sampling points shall proceed in every direction to the extent sufficient to result in a two

- dimensional grid completely

overlaying the sampling area.(3) Collect a sample at each point if the grid falls in the cleanup area. Anal yze all samples either

individually

or according to the compositing schemes provided in the procedures at §761.289. So long as every

sample collected at a grid point is analyzed as either an individual sample or as part of a composite sample, there are no other restrictions on how many samples are anal yz ed. (c) Selection of sample locations

— small cleanup sites. When a cleanup site is sufficientl y small or irregularly

shaped that a square grid with a grid interval of 1.5 meters will not result in a minimum of three sampling points for each t ype of bulk PCB remediation waste or porous surface at the cleanup site, there are two options. (1) Use a smaller square grid interval and the procedures in paragraph (b) of this section. (2) Use the following coordinate

- based random sampling scheme. If the site is recleaned based on the results of cleanup verification conducted in accordance with §761.61(a)(6), follow the procedures in this section for locating sampling points after the recleaning, but select three new pairs of sampling coordinates. (i) Beginning in the southwest corner (lower left when facing magnetic north) of th e area to be sampled, measure in centimeters (or inches) the maximum magnetic north

- south dimension of the area to be sampled. Next, beginning in the southwest corner, measure in centimeters (or inches) the maximum magnetic east

- west dimension of the area to be sampled. Designate the north

- south and east

- west dimensions (describing the west and south boundaries, respectivel y, of the area to be sampled), as the reference axes of a square

- based grid s ys tem. (ii) Use a random number table or random number gen erator to select a pair of coordinates that will locate the sample within the area to be sampled. The first coordinate in the pair is the measurement on the north

- south axis. The second coordinate in the pair is the measurement on the east

- west axis. Colle ct the sample at the intersection of an east

- west line drawn through the measured spot on the north

- south axis, and a north

- south line drawn through the measured spot on the east

- west axis. I f the cleanup site is irregularly shaped and this intersection fa lls outside the cleanup site, select a new pair of sampling coordinates. Continue to select pairs of sampling coordinates until three are selected for each t ype of bulk PCB remediation waste or porous surface at the cleanup site. (d) Area of inference. An aly tical results for an individual sample point apply to the sample point and to an area of inference extending to four imaginary lines parallel to the grid axes and one half grid interval distant from the sample point in four different directions. The are a of inference forms a square around the sample point. The sides of the square are parallel to the grid axes and one grid interval in length. The sample point is in the center of the square area of inference. The area of inference from a composite sample i s the total of the areas of the individual samples included in the composite. § 761.286 Sample size and procedure for collecting a sample. At each selected sampling location for bulk PCB remediation waste or porous surfaces, collect atleast 20 millili ters of waste, or a portion of sufficient weight for the chemical analyst to measure

the concentration of PCBs and still have sufficient anal yt ical detection sensitivity to reproducibl y measure PCBs at the levels designated in §761.61(a)(4). Use a core sam pler having a diameter  2 cm and  3 cm. Collect waste to a maximum depth of 7.5 cms. § 761.289 Compositing samples. Compositing is a method of combining several samples of a specific ty pe of bulk PCB remediation waste or porous surface from nearb y locations for a single chemical anal ys is. There are two procedures for compositing bulk PCB remediation waste samples. These procedures are based on the method for selecting sampling site locations in §761.283(b) and (c). The single chemical analy sis of a composite sample results in an averaging of the concentrations of its component samples. The area of inference of a composite is determined by the area of inference of each of its component samples as described in §761.283(d). Compositing is not mandatory

. However, if compositing is used, it must be performed in accordance with the following procedures. (a) Compositing in the field or in a laboratory . Compositing may occur either in the field or in a laboratory . Prepare composite samples using equal volume s of each constituent or component sample. Composited samples must be from the same ty pe of bulk PCB remediation waste or porous surface (see the example at §761.283(a)(2)). Mix composite samples thoroughl y. From each well

- mixed composite sample, take a po rtion of sufficient weight for the chemical anal ys t to measure the concentration of PCBs and still have sufficient anal yt ical detection sensitivity to reproducibl y measure PCBs at the levels designated in §761.61(a)(4). (b)(1) Compositing from samples col lected at grid points in accordance with §761.283(b). There are two kinds of composite sampling procedures depending on the original source of contamination of the site. (i) The first procedure is for sites with multiple point sources of contamination (su ch as an old electrical equipment storage area, a scrap y ard, or repair shop) or for unknown sources of contamination. Under this compositing scheme, composite a maximum of nine samples for each ty pe of bulk PCB remediation waste or porous surface at the c leanup site. The maximum dimensions of the area enclosing a nine grid point composite is two grid intervals bounded b y three collinear grid points (3.0 meters or approximately 10 feet long). Take all samples in the composite at the same depth. Assure that composite sample areas and individually anal yz ed samples completel y overlay the cleanup site. (ii) The second procedure is for a single point source of contamination, such as discharge into a large containment area (e.g., pit, waste lagoon, or evaporation pond), or a leak onto soil from a single drum or tank. Single point source contamination may be from a one

- time or continuous contamination. Composites come from two stages: an initial compositing area centered in the area to be sampled, and subsequent co mpositing areas forming concentric square zones around the initial compositing area. The center of the initial compositing area and each of the subsequent compositing areas is the origin of the grid axes.(A) Definition of the initial compositing area. Th e initial compositing area is based on a square

that contains nine grid points, is centered on the grid origin, and has sides two grid intervals long. The initial compositing area has the same center as this square and sides one half a grid interval more d istant from the center than the square. The initial compositing area has sides three grid intervals long. (B) Definition of subsequent compositing areas. Subsequent composite sampling areas are in concentric square zones one grid interval wide around the initial compositing area and around each successive subsequent compositing area. The inner boundary of the first subsequent compositing area is the outer boundary of the initial compositing area. The outer boundary of the first subsequent compositing area is centered on the grid origin, has sides one grid interval more distant from the grid origin than the inner boundary, and is two grid intervals longer on a side than the inner boundary . The inner boundary of each further subsequent compositing area is the outer boundary

of the previous subsequent compositing area. The outer boundary of each further subsequent compositing area is centered on the grid origin, has sides one grid interval more distant from the grid origin than the inner boundary, and is two grid intervals longer on a side than the inner boundary

. (C) Taking composite samples from the initial and subsequent compositing areas. (1) Select composite sampling areas from the initial compositing area and subsequent compositing areas such that all gri d points in the initial compositing area and subsequent compositing areas are part of a composite or individual sample. (2) A person may

include in a single composite sample a maximum of all nine grid points in the initial compositing area. The maximum number of grid points in a composite sample taken from a subsequent compositing area is eight. These eight grid points must be adjacent to one another in the subsequent compositing area, but need not be collinear. (2) Compositing from samples taken at grid points or pairs of coordinates in accordance with §761.283(c). Samples collected at small sites are based on selecting pairs of coordinates or using the sample site selection procedure for grid sampling with a smaller grid interval. (i) Samples collected from a grid having a smaller grid interval. Use the procedure in paragraph (b)(1)(i) of this section to composite samples and determine the area of inference for composite samples. (ii) Samples collected from pairs of coordinates. All three samples must b e composited. The area of inference for the composite is the entire area sampled. § 761.292 Chemical extraction and anal ys is of individual samples and composite samples. Use either Method 3500B/3540C or Method 3500B/3550B from EPA's SW

- 846, Test Method s for Evaluating Solid Waste, or a method validated under subpart Q of this part, for chemical extraction of PCBs from individual and composite samples of PCB remediation waste. Use Method 8082 from SW

- 846, or a method validated under subpart Q of this par t, to anal yz e these extracts for PCBs.§ 761.295 Reporting and recordkeeping of the PCB concentrations in samples.

(a) Report all sample concentrations for bulk PCB remediation waste and porous surfaces on a dry weight basis and as micrograms of PCBs per gram of sample (ppm by weight). (b) Record and keep on file for 3 years the PCB concentration for each sample or composite sample. § 761.298 Decisions based on PCB concentration measurements resulting from sampling. (a) For grid samples which are chemically anal yz ed individually , the PCB concentration applies to the area of inference as described in §761.283(d). (b) For grid samples analyzed as part of a composite sample, the PCB concentration applies to the area of inference of the composite samp le as described in §761.283(d) (i.e., the area of inference is the total of the areas of the individual samples included in the composite). (c) For coordinate pair samples analyzed as part of a composite sample, in accordance with §§761.283(c)(2) and 761. 289(b)(2)(ii), the PCB concentration applies to the entire cleanup site. Subpart P

(a) Large nearl y flat surfaces. Divide the entire surface into approximately 1 meter square portions and mark the portions so that they ar e clearly

identified. Determine the sample location in each portion as directed in §761.304. (1) For large nearl y flat surfaces contaminated b y a single source of PCBs with a uniform concentration, assign each 1 meter square surface a unique sequential number. (i) For three or fewer 1 meter square areas, sample all of the areas.(ii) For four or more 1 meter square areas, use a random number generator or table to select a

minimum of 10 percent of the areas from the list, or to select three areas, whichever is more. (2) For other large nearl y flat surfaces, sample all of the one meter square areas. (b) Small or irregularly

shaped surfaces. For small surfaces having irregular contours, such as hand tools, natural gas pipeline valves, and most exter ior surfaces of machine tools, sample the entire surface. An y person may select sampling locations for small, nearly flat surfaces in accordance with §761.308 with the exception that the maximum area in §761.308(a) is <1 meter square. (c) Preparation of s urfaces. Drain all free

- flowing liquids from surfaces and brush off dust or loose grit. § 761.304 Determining sample location. (a) For 1 square meter non

- porous surface areas having the same size and shape, it is permissible to sample the same 10 cm by 10 cm location or position in each identical 1 square meter area. This location or position is determined in accordance with §761.306 or §761.308. (b) If some 1 square meter surfaces for a larger non

- porous surface area have different sizes and shapes, s eparatel y select the 10 cm by 10 cm sampling position for each different 1 square meter surface in accordance with §761.308. (c) If non

- porous surfaces have been cleaned and the cleaned surfaces do not meet the applicable standards or levels, surfaces may be recleaned and resampled. When resampling surfaces previously

sampled to verify

cleanup levels, use the sampling procedures in §§761.306 through 761.316 to resample the surfaces. If an y sample site selected coincides with a previous sampling site, restart the sample selection process until all resampling sites are different from any previous sampling sites. § 761.306 Sampling 1 meter square surfaces b y random selection of halves. (a) Divide each 1 meter square portion where it is necessary to collect a surface wipe test sample into two equal (or as nearly equal as possible) halves. For example, divide the area into top and bottom halves or left and right halves. Choose the top/bottom or left/right division that produces halves having as close to the s hape of a circle as possible. For example, a square is closer to the shape of a circle than is a rectangle and a rectangle having a length to width ratio of 2:1 is closer to the shape of a circle than a rectangle having a length to width ratio of 3:1. (b) Assign a unique identifier to each half and then select one of the halves for further sampling with a random number generator or other device (i.e., by flipping a coin). (c) Continue selecting progressivel y smaller halves by dividing the previously selec ted half, in accordance with paragraphs (a) and (b) of this section, until the final selected half is larger than or equal to 100 cm2 and smaller than 200 cm2.(d) Perform a standard PCB wipe test on the final selected halves from each 1 meter square

port ion. (e) The following is an example of applying sampling by halves. Assume that the area to sample is a 1 meter square surface area (a square that has sides 1 meter long). Assign each half to one face of a coin. After flipping the coin, the half assigned to the face of the coin that is showing is the half selected. (1) Selecting the first half: (i) For a square shape the top/bottom halves have the same shape as the left/right halves when compared to a circle, i.e., regardless of which way the surface is divided, each half is 1 half meter wide b y 1 meter long. Therefore, divide the area either top/bottom or left/right. For selecting the first half, this example will select from left/right halves. (ii) A coin flip selects the left half. The dimensions of this selected surface area are 1 meter high and 1/2 meter wide. (2) Selecting the second half: (i) If the next selection of halves was left/right, the halves would be rectangles four times as long as they are wide ( 1/4 meter wide and 1 meter high). Halve s selected from top/bottom would be square ( 1/2 meter on a side). Therefore, select the next halves top/bottom, because the shape of the top/bottom halves (square) is closer to the shape of a circle than the shape of the left/right halves (long narrow rec tangles). (ii) A coin flip selects the top half. The dimensions of this selected surface area are 1/2 meter high and 1/2 meter wide. (3) Selecting the third half: (i) Just as for the selection of the first half, which divided the original square area, b oth the left/right and the top/bottom halves have the same shape when compared to a circle (both are rectangles having the same dimensions). Therefore, choose either left/right or top/bottom halves. This example will select from left/right halves. (ii) A coin flip selects the right half. The dimensions of this selected surface are 1/4 meter by 1/2 meter. (4) Selecting the fourth half: (i) If the next selection of halves was left/right, the halves would be rectangles four times as long as they are wide ( 1/8 meter wide and 1/2 meter high. Halves selected from top/bottom would be square ( 1/4 meter on a side). Therefore, select the next halves top/bottom, because the shape of the top/bottom halves (square) are closer to the shape of a circle than the shape of the left/right halves (long narrow rectangles).(ii) A coin flip selects the bottom half. The dimensions of this selected surface area are 1/4 meter

high and 1/4 meter wide. (5) Selecting the fifth half: (i) Just as for the selection of the first and third halves, both the left/right and the top/bottom halves have the same shape when compared to a circle (both are rectangles having the same dimensions). Therefore, choose either left/right or top/bottom halves. This example will select from left/right halves. (ii) A coin flip selects the right half. The dimensions of the selected surface are 1/8 meter by 1/4 meter. (6) Selecting the sixth half: (i) If the next selection of halves was left/right, the halves would be rectangles four times as long as they are wide ( 1/16 meter wide and 1/4 meter high. Halves selected from top/bottom would be square ( 1/8 meter on a side). Therefore, select the next halves top/bottom, because the shape of the top/bottom halves (square) are closer to the shape of a circl e than the shape of the left/right halves (long narrow rectangles). (ii) A coin flip selects the top half. The dimensions of this selected surface are 1/8 meter high and 1/8 meter wide or 12.5 cm by 12.5 cm. (7) Collect a standard wipe test sample in the sixth half. Since the dimensions of half of the sixth half would be 12.5 cm b y 6.25 cm, the area (approximately 78 cm2) would be less than the required 100 cm2 minimum area for the standard wipe test. Therefore, no further sampling b y halves is necessary

. Take the standard wipe test samples of the entire selected sixth half. § 761.308 Sample selection by random number generation on an y two

- dimensional square grid. (a) Divide the surface area of the non

- porous surface into rectangular or square areas having a maximum area of 1 square meter and a minimum dimension of 10 centimeters. (b) Measure the length and width, in centimeters, of each area created in paragraph (a) of this section. Round off the number of centimeters in the length and the width measurements to the nearest centimeter. (c) For each 1 square meter area created in accordance with paragraph (a) of this section, select two random numbers: one each for the length and width borders measured in paragraph (b) of this section. An eligible rando m number can be from zero up to the total width, minus 10 centimeters. (d) Locate the 10 centimeter b y 10 centimeter sample.(1) Orient the 1 square meter surface area so that, when you are facing the area, the length is left

to right and the width is to p to bottom. The origin, or reference point for measuring selected random numbers of centimeters to the sampling area, is on the lower left corner when facing the surface. (2) Mark the random number selected for the length distance, in centimeters, from the origin to the right (at the bottom of the area away from the origin). (3) From the marked length distance on the bottom of the area, move perpendicularl y up from the bottom of the area into the area for the distance randoml y selected for the width. (4 ) Use the point determined in paragraph (d)(3) of this section as the lower left corner of the 10 centimeter b y 10 centimeter sample. § 761.310 Collecting the sample. Use the standard wipe test as defined in §761.123 to sample one 10 centimeter by 10 c entimeter square (100 cm2) area to represent surface area PCB concentrations of each square meter or fraction of a square meter of a nearl y flat, non

- porous surface. For small surfaces, use the same procedure as for the standard wipe test, onl y sample the entire area, rather than 10 centimeter b y 10 centimeter squares. § 761.312 Compositing of samples. For a surface originall y contaminated by a single source of PCBs with a uniform concentration, it is permissible to composite surface wipe test samples and to use the composite measurement to represent the PCB concentration of the entire surface. Composite samples consist of more than one sample gauze extracted and chemically anal yz ed together resulting in a single measurement. The composite measurement r epresents an arithmetic mean of the composited samples. (a) Compositing samples from surfaces to be used or reused. For small or irregularl y shaped surfaces or large nearl y flat surfaces, if the surfaces are contaminated b y a single source of PCBs with a uniform concentration, composite a maximum of three adjacent samples. (b) Compositing samples from surfaces to be disposed of off

- site or on

- site. (1) For small or irregularl y shaped surfaces, composite a maximum of three adjacent samples. (2) For large nearl y flat surfaces, composite a maximum of 10 adjacent samples. § 761.314 Chemical analy sis of standard wipe test samples. Perform the chemical analy sis of standard wipe test samples in accordance with §761.272. Report sample results in micrograms pe r 100 cm2. § 761.316 Interpreting PCB concentration measurements resulting from this sampling scheme.(a) For an individual sample taken from an approximately 1 meter square portion of the entire surface area and not composited with other samples, the status of the portion is based on the surface concentration measured in that sample. If the sample surface concentration is not equal to or lower than the cleanup level, by inference the entire 1 meter area, and not just the immediate area where the sample was taken, is not equal to or lower than the cleanup level. (b) For areas represented by the measurement results from compositing more than one 10 centimeter b y 10 centimeter sample, the measurement for the composite is the measurement for the entire are a. For example, when there is a composite of 10 standard wipe test samples representing 9.5 square meters of surface area and the result of the analysis of the composite is 20  g/100 cm2, then the entire 9.5 square meters has a PCB surface concentration of 20  g/100 cm2, not just the area in the 10 cm b y 10 cm sampled areas. (c) For small surfaces having irregular contours, where the entire surface was sampled, measure the surface area. Divide 100 cm2 by the surface area and multiply this quotient by

the t otal number of micrograms of PCBs on the surface to obtain the equivalent measurement of micrograms per 100 cm2. Subpart Q

- Implementing Alternative Extraction and Chemical Anal ysis Procedures for Non

- liquid PCB Remediation Waste Samples
Source: 63 FR 35468, June 29, 1998, unless otherwise noted. § 761.320 Applicability. This subpart describes self

- implementing comparison testing requirements for chemical extraction and chemical anal ys is methods used as an alternative to the methods required in §§761.272 or 761.292. Any person conducting comparison testing under this subpart must comply with the requirements of §761.80(i), including notification. Use alternative methods onl y after successful completion of these comparison testing requirements and after documentation of the results of the testing. § 761.323 Sample preparation. (a) The comparison study requires anal ys is of a minimum of 10 samples weighing at least 300 grams each. Samples of PCB remediation waste used in the comparison study must meet the following three requirements. (1) The samples must either be taken from the PCB remediation waste at the cleanup site, or must be the same kind of material as that waste. For example, if the waste at the cleanup site is sandy soil, y ou must use the same kind of sand y s oil in the comparison study . Do not use unrelated materials such as clay soil or dredged sediments in place of sand y soil. (2) PCB remediation waste may contain interferences which confound or hamper sample extraction and chemical anal ys is. These interferences may be from chemicals or other attributes preexisting in the waste material, resulting from the PCB contamination source, or resulting fromtreatment to remove or destroy PCBs. Comparison study samples must also contain these interfering materials to demonstrate successful analy sis in their presence. For example, a PCB remediation waste may

have been co

- disposed with chlorobenzene solvents or chlorinated pesticides. These chlorinated compounds would have to be present in the co mparison study compounds at the same levels found, or at the highest levels expected to be found, in the PCB remediation waste. As another example, for PCB remediation waste which had been solvent washed with liquid amines to remove PCBs, comparison study samples would have to contain concentrations of these amines at the same levels found, or at the highest levels expected to be found, in the PCB remediation waste. (b) Prior to initiating the comparison study , confirm the following PCB concentrations in the comparison study

samples using the methods specified in §761.292. All samples of non

- liquid PCB remediation waste must have PCB concentrations between 0.1 and 150 ppm. (1) A minimum of three comparison study samples must have PCB concentrations above the cleanup level specified for the site in §761.61(a)(4) and a minimum of three comparison study samples must have PCB concentrations below the specified cleanup level. (2) At least one comparison study sample must have a PCB concentration  90 percent and  100 percent of the cleanup level. (3) At least one comparison study sample must have a PCB concentration  100 percent and  110 percent of the cleanup level. (c) If the comparison study samples do not have the concentrations or concentration ranges requ ired b y paragraph (b) of this section, for purposes of use in this chemical extraction and chemical analy sis comparison study , a person may adjust PCB concentrations by dilution. Any excess material resulting from the preparation of these samples, which is not used as an anal yt ical sample, is regulated as the PCB concentration in the component having the highest PCB concentration of the component materials in the sample. § 761.326 Conducting the comparison study

. Extract or anal yz e the comparison study samples using the alternative method. For an alternative extraction method or alternative anal yt ical method to be comparable to the methods required in §761.292, all of the following conditions must be met. (a) All samples having PCB concentrations greate r than or equal to the level of concern, as measured b y the methods required in §761.292, are found to be greater than or equal to the level of concern as measured by the alternative method (no false negatives). (b) Onl y one sample which contains PCBs at a level less than the level of concern, as measured by the methods required in §761.292, is found to have a PCB concentration greater than the level of concern as measured by the alternative method (false positive); and all other samples which contain PCBs at levels less than the level of concern, as measured b y the methods required in §761.292, are found b y the alternative method to have PCBs less than the level of concern (thereare no additional false positives).

- Site Disposal, in Accordance With §761.61 Source: 63 FR 35469, June 29, 1998, unless otherwise noted. § 761.340 Applicability. Use the procedures specified in this subpart to sample the following t ypes of waste when it is necessary to anal yz e the waste to determine PCB concentration or leaching characteristics for storage or disposal. (a) Exist ing accumulations of non

- liquid, non

- metal PCB bulk product waste. (b) Non

- liquid, non

- metal PCB bulk product waste from processes that continuously generate new waste. (c) Non

- liquid PCB remediation waste from processes that continuously generate new wa ste, that will be sent off

- site for disposal. § 761.345 Form of the waste to be sampled. PCB bulk product waste and PCB remediation waste destined for off

- site disposal must be in the form of either flattened or roughly conical piles. This subpart also contains a procedure for contemporaneous sampling of waste as it is being generated. § 761.346 Three levels of sampling. To select a sample of the waste and prepare it for chemical extraction and analy sis, there are three required levels of random sampling. (a) First, select a single 19

- liter (5 gallon) portion from a composite accumulated either contemporaneousl y with the generation of the waste or by sampling an existing pile of waste. Collection procedures for the first level of sampling from exist ing piles of waste are in §761.347. Collection procedures for the first level of sampling from a contemporaneous generation of waste are in §761.348. Compositing requirements and requirements for the subsampling of composite samples to result in a single 1 9

- liter sample are in §761.350. Send the 19

- liter sample to the laboratory

for the second and third levels of sampling, including particle size reduction for leach testing and drying as required b y §761.1(b)(4). (b) Second, at the laboratory , select one quarter of the 19

- liter sample. Procedures the laboratory must use for this second level of sample selection appear in §761.353. (c) Third, select a 100 gram subsample from the second level subsample. Procedures thelaboratory must use for this third level of sample selection appear in §761.355. § 761.347 First level sampling

— waste from existing piles. (a) General. Sample piles that are either specifically configured for sampling (see paragraph (b) of this section) or that are of conical shape (see paragraph (c) of this section). If sampling from either of these shapes is not possible, conduct contemporaneous sampling, in accordance with the procedures in §761.348, or obtain the approval of the Regional Administrator for an alternate sampling plan in accordance with §761.62(c). (b) Specifically

configured piles. A specifically configured pile is a single flattened pile in the shape of a square or rectangle having no restrictions on length or width but restricted to 30 cm (1 foot) in depth. A square sh aped pile facilitates sampling site selection for the first level sample. Select eight 19

- liter samples from the pile and composite them into one 19

- liter sample as follows: (1) Divide the pile into quarters. (2) Divide each of the quarter sections into quarters (i.e., into sixteenths of the original pile). (3) Select two sixteenths from each of the four quarters, according to one of the two following options: (i) Randomly

select the two sixteenths from one quarter and sample the sixteenths occupying th e same positions in each of the other three quarters. (ii) Randomly

select two sixteenths from each of the four quarters (i.e., perform a random selection four different times). (4) At this point the eight selected sixteenths undergo further division and sample selection. Divide each of the eight selected sixteenths into four equal parts. Using a random number generator or random number table, select one of the four equal parts from each of the eight equal areas. If each of the four equal parts has a volume >76 liters when projected downwards 30 cm, continue to divide each selected area into four equal parts, and select one of the parts, until each selected area has a volume of <76 liters but  19 liters. When projected to a depth of 30 cm, a square having a 25 cm side or a circle having a diameter of approximately 28.5 cm equals a volume of approximately 19 liters. The volume of 76 liters is equal to the volume enclosed b y a square having a side of 50 cm (or other shape having an area of 250 cm2) projected to a depth of 30 cm. (5) Take one sample of approximately 19 unsorted liters of waste from each of the eight selected areas. Place each sample into a separate 19

- liter container, allowing only sufficient space at the top of the container to secure the lid

. (6) Composite the eight 19

- liter samples in accordance with §761.350. (c) Conical

- shaped piles. If it is necessary to sample a pile which is too large to be spread on thesite to a uniform thickness of 1 foot or 30 cm, or if there are too man y piles to spread out in the

space available, use the following procedure to sample the piles. This procedure assumes that the shape of the piles is analogous to a cone; that is, having a circular base with PCB bulk product waste or PCB remediation waste destined fo r off

- site disposal stacked up uniformly to a peak that is a point centered above the center of the circular base. Collect eight 19

- liter samples as follows: (1) Collecting samples from more than one pile. If the PCB bulk product waste or PCB remediation waste consists of more than one pile or container, assign each pile or container an integer number and then generate seven random integer numbers to select the piles from which yo u will collect samples. It is possible that this random selection procedure w ill result in selecting the same pile number more than once, even if seven or more piles are present. If so, sample the pile once and restart the sampling collection process to collect additional samples. Do not collect multiple samples from the same locat ion in the pile. (2) Collecting samples from a single pile. If only one pile or container is present, collect all eight samples from the same pile. (3) Setting up the sample site selection sy stem from a pile. L ocate a sample in a pile by the use of three parameters: a particular radial direction, “r,” from the peak at the center of the pile to the outer edge at the base of the pile; a point, “s,” along that radial direction between the peak of the pile and the outer edge of the base of the pile; and a dep th, “t”, beneath point “s.” The top of the sample material will be below depth t, at point s, on radius r. Use a rod, dowel, stake, or broom handle as a marker. Nail or otherwise fasten to the top of the marker two pieces of string or cord of sufficient le ngth and strength to reach from the top of the marker at the top of the pile to the farthest peripheral edge at the bottom of the pile, when the marker is positioned at the top or apex of the pile. Pound or push the marker into the top center (apex) of the pile, downward toward the center of the base. Insert the marker for at least 30 cm or one foot until the marker is rigidl y standing on its own, even when the cord is pulled tight to the bottom peripheral edge of the pile. Ensure that the marker protrudes from the top of the pile sufficiently to allow the strings to move easily

around the pile when they are pulled tight. Select the three parameters and the sampling location as follows: (i) Determine the radial component (r) of the location for each sample. (A) Tie to a stake or otherwise fasten one of the strings at “b,” the bottom of the pile, as a reference point for finding r. (B) Measure the circumference “c,” the distance around the bottom of the pile. Determine r from b in one of two way s: (1) Multiply

c b y a randomly

generated fraction or percentage of one. (2) Select a random number between one and the total number of centimeters in c. (C) L ocate r by

starting at b, the place where the fixed string meets the base of the pile, andtravel cloc kwise around the edge of the pile at the base for the distance y ou selected in paragraph

(c)(3)(i)(B) of this section. (D) Fasten the second string at the selected distance. The second string marks the first parameter r. (ii) Determine the second paramet er s of the location for each sample. (A) Measure the distance, l, along the string, positioned in paragraph (c)(3)(i)(D) of this section, from the top to the bottom of the pile at the selected radial distance r. Determine the distance s from l in one of two ways: (1) Multiply

l by a randomly

generated fraction or percentage of one. (2) Select a random number between one and the total number of centimeters in l. (B) Mark, for example by placing a piece of tape on the string positioned according to paragraph (c)(3)(i)(D) of this section, the distance s, up from the bottom of the pile on the string at r. (iii) Determine the third and final parameter t of the location for each sample. (A) Mark and number 1 cm intervals from one end of a rigid device, for example a rod, dowel, stake, or broom handle, for measuring the distance from the top of the pile to the bottom at the point s selected in paragraph (c)(3)(ii)(B) of this section. The marked and numbered device shall be of sufficient strength to be forced down through the maximum depth of the pile and sufficient length to measure the depth of the waste in the pile at any point. (B) Take the measuring device, constructed according to paragraph (c)(3)(iii)(A) of this section, and at position s, push the end of the device marked with zero straight down into the pile until it reaches the bottom of the pile or ground level. The vertical distance “v” is the number of centimeters from the surface of the pile at point s on the string to the bottom of the pile or gr ound level. Read the distance v on the measuring device at the surface of the pile. From the distance v, determine t, in one of two way s: (1) Randomly

generate a fraction of one and multiply the fraction times v. (2) Select a random number between zero and the total number of centimeters of the vertical distance v. (iv) Dig a hole straight down into the pile for t centimeters (inches) from the surface of the pile at s. (v) At depth t, directl y under the s mark on the string, outline the top of the samp le container and collect (shovel) all waste under the outline in the following order of preference in paragraphs (c)(3)(v)(A) through (c)(3)(v)(C) of this section. It is possible that some of the eight sampling locations will not provide 19 liters of sampl e.(A) For a depth of 30 cm.

(B) Until the container is full. (C) Until the ground level is reached. (d) Compositing the samples. Composite the eight 19

- liter samples and subsample in accordance with §761.350. Send the subsample to a laboratory for fur ther sampling as described in §§761.353 and 761.355 and for chemical extraction and anal ys is. If there is insufficient sample for a 19

- liter sample from the composite sample composed of the eight iterations of sample site selection, according to the proced ures in paragraphs (c)(3)(i) through (c)(3)(v) of this section, select additional sample sites, collect additional samples and composite the additional waste in the samples until a minimum of 19 liters is in the composite. [63 FR 35469, June 29, 1998, as amended at 64 FR 33762, June 24, 1999] § 761.348 Contemporaneous sampling. Contemporaneous sampling is possible when there is active generation of waste and it is possible to sample the waste stream as it is generated. Collect eight 19

- liter samples as follows. (a) Collect each sample by filling a 19

- liter (5 gallon) container at a location where the PCB bulk product waste is released from the waste generator onto a pile or into a receptacle container before the waste reaches the pile or receptacle con tainer. (b) Determine a sample collection start time using a random number generator or a random number table to select a number between 1 and 60. Collect the first sample at the randoml y selected time in minutes after start up of the waste output, or if the waste is currentl y being generated, after the random time is selected. For example, if the randomly selected time is 35, begin collection 35 minutes after the start up of waste generation. Similarly, if waste output is ongoing and the random start dete rmination occurred at 8:35 a.m., collect the first sample at 9:10 a.m. (35 minutes after the random start determination). (c) Collect seven more samples, one every 60 minutes after the initial sample is collected. If the waste output process stops, stop the 60

–minute interval time clock. When the process restarts, restart the 60

–minute interval time clock and complete the incomplete 60

–minute interval. (d) Composite the eight 19

- liter samples and subsample in accordance with §761.350. § 761.350 Subsampling from composite samples. (a) Preparing the composite. Composite the samples (eight from a flattened pile; eight or more from a conical pile; eight from waste that is continuously generated) and select a 19

- liter subsample for shipment to the ch emical extraction and anal ys is laboratory for further subsampling. There are two options for the preparation of the composite:(1) Option one. Place all of the contents of all 19

- liter samples that y ou collected into a 209 liter

(55 gallon) drum or similar sized, cylinder

- shaped container. Completel y cl ose the container, and roll it 10 or more complete revolutions to mix the contents. (2) Option two. Add the 19

- liter samples one at a time to a 209 liter (55 gallon) drum. Between the addition of each 19

- li ter sample, stir the composite using a broom handle or similar long, narrow, sturd y rod that reaches the bottom of the container. Stir the mixture for a minimum of 10 complete revolutions of the stirring instrument around the container at a distance approx imately half way between the outside and center of the container. (b) Selecting a 19

- liter subsample from the composite. Once the composite is mixed, pour the mixture of waste out on a plastic sheet and either divide it into 19

- liter size piles or make on e large pile. (1) From 19

- liter sized piles, use a random number generator or random number table to select one of the piles. (2) From one large pile, flatten the pile to a depth of 30 cm and divide it into 4 quarters of equal size. Use a random number g enerator or random number table to select one quarter of the pile. Further divide the selected quarter pile into 19

- liter portions and use a random number generator or random number table to select one 19

- liter portion. A square having a 25 cm side or a ci rcle having a diameter of approximately 28.5 cm when projected downwards 30 cm equals approximately

19 liters. (c) Transferring the sample to the anal yt ical laboratory . Place the selected 19

- liter subsample in a container, approved for shipment of the sample, to the chemical extraction and anal ys is laboratory , for the next step in sample selection in accordance with §761.353. § 761.353 Second level of sample selection. The second level of sample selection reduces the size of the 19

- liter subsample that was collected according to either §761.347 or §761.348 and subsampled according to §761.350. The purpose of the sample size reduction is to limit the amount of time required to manually cut up larger particles of the waste to pass through a 9.5 millimeter (mm) screen. (a) Selecting a portion of the subsample for particle size reduction. At the chemical extraction and anal ys is laboratory , pour the 19

- liter subsample onto a plastic sheet or into a pan and divide the subsample into quarters. Use a random number generator or random number table to select one of these quarters. (b) Reduction of the particle size by the use of a 9.5 mm screen. Collect the contents of the selected quarter of waste resulting from conducting the procedures in paragraph (a) of this section and shake the waste in a 9.5 mm screen. Separate the waste material which passes through the screen from the waste material which does not pass through the screen. Manuall y cut or otherwise reduce the size of all parts of the waste portion which d id not pass through the 9.5mm screen, such that each part of the waste shall pass through the 9.5 mm screen b y shaking.

(c) Drying the reduced particle size waste. Dry all of the waste portion resulting from conducting the procedures in paragraph (b) of this section, from 10 to 15 hours in a drying oven at 100 ̊ C. Allow the dried waste to cool to room temperature. (d) Mixing the dried waste. Place all of the waste resulting from conducting the procedures in paragraph (c) of this section in a 19

- liter pai l or similarly sized, cylinder

- shaped container. Mix the dried material according to one of the two following options: (1) First mixing option. Completely close the container and roll the container a minimum of 10 complete revolutions to mix the contents. (2) Second mixing option. Use a sturd y stirring rod, such as a broom handle or other device that reaches the bottom of the container, to stir the waste for a minimum of 10 complete revolutions around the container at a distance approximately half way between the outside and the center of the container. § 761.355 Third level of sample selection. The third level of sample selection further reduces the size of the subsample to 100 grams which is suitable for the chemical extraction and anal ys is proced ure. (a) Divide the subsample resulting from conducting the procedures in §761.353 of this part into 100 gram portions. (b) Use a random number generator or random number table to select one 100 gram size portion as a sample for a procedure used to simul ate leachate generation. (c) Dry the 100 gram sample, selected after conducting the procedure in paragraph (b) of this section, for 10 to 15 hours in a drying oven at 100 ̊ C and cool it to the analytical laboratory room temperature before analysis using a procedure used to simulate leachate generation. This sample was dried previously

in the larger quantity

sample at the second level of sampling (§761.353(c)) and is dried a second time here (in the third level of sample selection). This dried and cooled sample must weigh at least 50 grams. (d) If the dried and cooled sample weighs <50 grams, select additional 100 gram portions of sample one at a time b y repeating the directions in paragraph (b) and (c) of this section, and add each additional 100 gram port ion of sample to the first 100 gram portion until at least 50 grams of dried material is in the sample to be anal yz ed using a procedure used to simulate leachate generation. § 761.356 Conducting a leach test. No method is specified as a procedure used to simulate leachate generation.§ 761.357 Reporting the results of the procedure used to simulate leachate generation.

Report the results of the procedure used to simulate leachate generation as micrograms PCBs per liter of extract from a 100 gram sample of dry bulk product waste. Divide 100 grams by the grams in the sample and multiply this quotient by

the number of micrograms PCBs per liter of extract to obtain the equivalent measurement from a 100 gram sample. § 761.358 Determining the PCB concentration of samples of waste. Use either Method 3500B/3540C or Method 3500B/3550B from EPA's SW

- 846, Test Methods for Evaluating Solid Waste, or a method validated under subpart Q of this part, for chemical extraction of PCBs from individual and composite samples of PCB bulk product waste. Use Method 8082 from SW

- 846, or a method validated under subpart Q of this part, to anal yz e these extracts for PCBs. § 761.359 Reporting the PCB concentrations in samples. Report all sample concentrations as ppm by weight on a dry weight basis. Subpart S

—Double Wash/Rinse Method for Decontaminating Non

- Porous Surfaces Source: 63 FR 35472, June 29, 1998, unless otherwise noted. § 761.360 Background. The double wash/rinse procedure is used to quickly and effect ivel y remove PCBs on surfaces. It is important to select and use the proper cleanup equipment, to conduct the procedure correctly so as not to redistribute PCBs, and to comply with disposal requirements for all cleanup materials. § 761.363 Applicability

. The double wash/rinse procedure includes two washing steps and two rinsing steps. The two washing and rinsing steps are slightly different depending on whether a contaminated surface was relativel y clean before the spill (see §761.372), or whether the s urface was coated or covered with dust, dirt, grime, grease or another absorbent material (see §761.375). § 761.366 Cleanup equipment. (a) Use scrubbers and absorbent pads that are not dissolved by the solvents or cleaners used, and that do not shred, crumble, or leave visible fragments on the surface. Scrubbers and absorbent pads used to wash contaminated surfaces must not be reused. Scrubbers and absorbent pads for rinsing must not contain  2 ppm PCBs. Scrubbers and absorbent pads used in the second r inse of contaminated surfaces may be reused to wash contaminated surfaces. (b) Capture and contain all solvents and cleaners for reuse, decontamination, or disposal. Cleanorganic solvents contain <2 ppm PCBs. Clean water contains <3 ppb PCBs.

§ 761.369 Pre

- cleaning the surface. If visible PCB

- containing liquid is present on the surface to be cleaned, thoroughl y wipe or mop the entire surface with absorbent paper or cloth until no liquid is visible on the surface. § 761.372 Specific requirements for relativel y cl ean surfaces. For surfaces that do not appear dust y or grim y before a spill, such as glass, automobile surfaces, newly

- poured concrete, and desk tops, use the double wash/rinse procedures in this section. (a) First wash. Cover the entire surface with organic solvent in which PCBs are soluble to at least 5 percent b y weight. Contain and collect an y runoff solvent for disposal. Scrub rough surfaces with a scrub brush or disposable scrubbing pad and solvent such that each 900 cm2 (1 square foot ) of the surface is alway s very wet for 1 minute. Wipe smooth surfaces with a solvent

soaked, disposable absorbent pad such that each 900 cm2 (1 square foot) is wiped for 1 minute. Any surface <1 square foot shall also be wiped for 1 minute. Wipe, mop, and /or sorb the solvent onto absorbent material until no visible traces of the solvent remain. (b) First rinse. Wet the surface with clean rinse solvent such that the entire surfaces is very wet for 1 minute. Drain and contain the solvent from the surface. Wipe the residual solvent off the drained surface using a clean, disposable absorbent pad until no liquid is visible on the surface. (c) Second wash. Repeat the procedures in paragraph (a) of this section. The rinse solvent from the first rinse (paragraph (b) of this section) may be used. (d) Second rinse. Repeat the procedures in paragraph (b) of this section. § 761.375 Specific requirements for surfaces coated or covered with dust, dirt, grime, grease, or another absorbent material. (a) First wash. Cover the entire surface with concentrated or industrial strength detergent or non

ionic surfactant solution. Contain and collect all cleaning solutions for proper disposal. Scrub rough surfaces with a scrub brush or scrubbing pad, adding cleaning solution such that the surface is alway s very

wet, such that each 900 cm2 (1 square foot) is washed for 1 minute. Wipe smooth surfaces with a cleaning solution

- soaked disposable absorbent pad such that each 900 cm2 (1 square foot) is wiped for 1 minute. Wash any s urface <1 square foot for 1 minute. Mop up or absorb the residual cleaner solution and suds with an clean, disposable, absorbent pad until the surface appears dry . This cleaning should remove any residual dirt, dust, grime, or other absorbent materials lef

t on the surface during the first wash. (b) First rinse. Rinse off the wash solution with 1 gallon of clean water per square foot and capture the rinse water. Mop up the wet surface with a clean, disposable, absorbent pad until the surface appears dry

.( c) Second wash. Follow the procedure in §761.372(a).

(d) Second rinse. Follow the procedure in §761.372(b). § 761.378 Decontamination, reuse, and disposal of solvents, cleaners, and equipment. (a) Decontamination. Decontaminate solvents and non

- porous surfaces on equipment in accordance with the standards and procedures in §761.79(b) and (c). (b) Reuse. A solvent may be reused so long as its PCB concentration is <50 ppm.

— Comparison Study for Validating a New Performance

- Based Decontamination Solvent Under §761.79(d)(4)
Source: 63 FR 35473 , June 29, 1998, unless otherwise noted. § 761.380 Background. This subpart provides self

- implementing criteria for validating the conditions for use in performance

- based decontamination of solvents other than those listed in §761.79(c)(3) and (c)(4). An y person may

use this subpart for validating either a chemical formulation or a product with a trade name whether or not the constituents of the product are proprietary

. § 761.383 Applicability. Use the self

- implementing decontamination procedure onl y on smooth, non

- porous surfaces that were once in contact with liquid PCBs. Decontamination procedures under this subpart shall exactly parallel §761.79(c)(3) and (c)(4), except that the procedures described in §761.79(c)(3)(iii) and (c)(3)(iv) and (c)(4) (iii), (c)(4)(iv) and (c)(4)(vii) may be revised to contain parameters validated in accordance with this subpart. § 761.386 Required experimental conditions for the validation study and subsequent use during decontamination. The following experimental conditions apply for any solvent: (a) Temperature and pressure. Conduct the validation study and perform decontamination at room temperature (from  15 ̊ C to  30 ̊ C) and at atmospheric pressure.(b) Agitation. L imit the movement in the solvent to the shor t

- term movement from placing the contaminated surface into the soak solvent and from removing the surface from the soak solvent. (c) Time of soak. Soak the surface for a minimum of 1 hour. (d) Surface conditions for the validation study . Prior to beginni ng the validation study , ensure that there are no free

- flowing liquids on surfaces and that surfaces are dry (i.e., there are no liquids visible without magnification). Also ensure that surfaces are virtually free from non

liquid residues, corrosion, and o ther defects which would prevent the solvent from freely circulating over the surface. (e) Confirmatory

sampling for the validation study. Select surface sample locations using representative sampling or a census. Sample a minimum area of 100 cm2 on each individual surface in the validation study . Measure surface concentrations using the standard wipe test, as defined in §761.123, from which a standard wipe sample is generated for chemical analy sis. Guidance for wipe sampling appears in the document entitl ed “Wipe Sampling and Double Wash/Rinse Cleanup as Recommended b y the Environmental Protection Agency PCB Spill Cleanup Policy ,” available from the TSCA Assistance Information Service, Environmental Protection Agency , 1200 Pennsylvania Ave., NW., Washingto n, DC 20460. (f) Concentration of PCBs. The method validated may be used onl y to decontaminate surfaces containing PCBs at concentrations on which the validation study was performed and lower concentrations. § 761.389 Testing parameter requirements.
T here are no restrictions on the variable testing parameters described in this section which may be used in the validation study . The conditions demonstrated in the validation study for these variables shall become the required conditions for decontaminatio n using the solvent being validated and shall replace the comparable conditions in §761.79(b)(3) through (b)(6). There are limited potential options for varying a single requirement in this section. If y ou change one of these variable requirements, change it only in the way

listed in this section and do not change any other validated conditions. I f you desire to change more than one of the requirements in this section, y ou must conduct a new study to validate the decontamination under the desired conditions

. (a) The stud y apparatus is not standardized. Critical components of the study are the PCB material (for example MODEF or some other spiking solution), the volume of the soaking solvent, and the area of the contaminated surface. The EPA study used beaker s and shallow dishes as the experimental vessels to contain the surface and solvent during the soaking process. In order to minimize surface

- to

- volume ratios, it is convenient to utilize flat contaminated surfaces and shallow solvent containers. During the validation study , use the same ratio of contaminated surface area to soak solvent volume as would be used during actual decontamination. It is also permissible to use a smaller surface area to soaking solvent volume than used in the validation study , so l ong as all other required parameters are used as validated in the confirmation required in §761.386 (a) through (f), and paragraphs (a) through (c) of thissection. Do not use a larger surface

- area - to

- solvent

- volumes ratio or different kind of solvent

base d on the results of the validation study

. (b) Except for the minimum soak time of 1 hour (as required in §761.386(c)), the length of soak time is not otherwise restricted in the validation study . The soak time used in the validation study , however, is a use requirement for subsequent decontamination using the solvent being validated. It is permissible to use longer soak times for decontamination than the soak time used in the validation study , if all other parameters required in §761.386, and paragraphs ( a) and (c) of this section are used. (c) There is no restriction on the kind of material containing PCBs to use to create the surface contamination for the validation study . There is also no restriction on the level of starting PCB surface concentration. It is permissible to use lower concentrations of PCB than the concentration used in the validation study , if all other parameters required in §761.386 (a) through (f), and paragraphs (a) through (c) of this section are used. § 761.392 Preparing validati on study samples. (a)(1) To validate a procedure to decontaminate a surface contaminated with a spill from liquid of a known concentration, contaminate (spike) the surface to be used in the validation study as follows: (i) Use a spiking solution made of PCBs mixed with a solvent to contaminate clean surfaces. Clean surfaces are surfaces having PCB surface concentrations <1  g/100 cm2 before intentionally

contaminating the surface. (ii) Prior to contaminating a surface for the validation study , mark the s urface sampling area to assure that it is completely covered with the spiking solution. (iii) Deliver the spiking solution onto the surface, covering all of the sampling area. Contain an y liquids which spill or flow off the surface. Allow the spiking solution to drip drain off into a container and then evaporate the spiking solution off the contaminated surface prior to beginning the validation study . Contaminate a minimum of eight surfaces for a complete validation study

. (iv) As a qualit y control step, test at least one contaminated surface to determine the PCB concentration to verify

that there are measurable surface levels of PCBs resulting from the contamination before soaking the surface in the decontamination solvent. The surface levels of PCBs on the contaminated surfaces must be  20  g/100 cm2. (2) To validate a procedure to decontaminate a specified surface concentrations of PCBs as measured b y a standard wipe sample, contaminate a minimum of 10 surfaces. Contaminate all the surfaces identicall y following the procedures in paragraph (a)(1) of th is section and measure the PCB surface concentrations of at least three of the surfaces using a standard wipe test to establish a surface concentration to be included in the standard operating procedure. The surface levels of PCBs on the contaminated surfa ces must be  20  g/100 cm2.(b) [Reserved]

§ 761.395 A validation study

. (a) Decontaminate the following prepared sample surfaces using the selected testing parameters and experimental conditions. Take a standard wipe sample of the decontaminated surf ace. (1) At least one uncontaminated surface. The surface levels of PCBs on the uncontaminated surface must be <1  g/100 cm2. (2) At least seven contaminated surfaces. (b)(1) Use SW

- 846, Test Methods for Evaluating Solid Waste methods for sample extraction and chemical analy sis as follows: Use Method 3500B/3540C or Method 3500B/3550B for the extraction and cleanup of the extract and Method 8082 for the chemical analy sis, or methods validated under subpart Q of this part. (2) Report all validation study surface sample concentrations on the basis of micrograms of PCBs per 100 cm2 of surface sampled. (c) Following completion of the validation study , measurements from the contaminated surfaces must have an arithmetic mean of  10  g/100 cm2. If the ar ithmetic mean is >10  g/100 cm2, then the validation study

failed and the solvent may not be used for decontamination under §761.79(d)(4) according to the parameters tested. § 761.398 Reporting and recordkeeping. (a) Submit validation study results to the Director, National Program Chemicals Division (NPCD), (7404), Office of Pollution Prevention and Toxics, 1200 Pennsylvania Ave., NW., Washington, DC, prior to the first use of a new solvent for alternate decontamination under §761.79(d)(4). The use of a new solvent is not TSCA Confidential Business Information (CBI). From time to time, the Director of NPCD will confirm the use of validated new decontamination solvents and publish the new solvents and validated decontamination procedures in the Federal R egister. (b) An y person may

begin to use solvent validated in accordance with this subpart at the time results are submitted to EPA. (c) Record all testing parameters and experimental conditions from the successful validation study into a standard operat ing procedure (SOP) for reference whenever the decontamination procedure is used. Include in the SOP the identity of the soaking solvent, the length of time of the soak, and the ratio of the soak solvent to contaminated surface area during the soaking proc ess. Also include in the SOP the maximum concentration of PCBs in the spilled material and the identity

of the spilled material, and/or the measured maximum surface concentration of the contaminated surface used in the validation study . Record and keep the results of the validation study as an appendix to the SOP. Include in this appendix, the solvent used to make the spikingsolution, the PCB concentration of the spiking solution used to contaminate the surfaces in the

validation study , and all of the vali dation study testing parameters and experimental conditions.
