' nummary: Sections 103(ja) and 103(b) of . the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), qs amended, require that persons in Charge of vessels or facilities from which a hazardous substance has been released in quantities that are equal to or greater than its reportable quantity (RQ) immediately notify the IjJational Response Center of the release. Section 102(b) of CERCLA establishes RQs for releases of designated hazardous substances at one pound except those for which RQs were established pursuant to section 311(d)(4) of the Clean Water Act (CWA). Section 102(a) authorises the Administrator of the U.S. Environmental Protection Agency (EPA) to adjust RQs for hazardous substances and to designate as hazardous substances those substances whichj when released into the environment, may present substantial danger to thi public health or welfare or the environment. A final rule published on April 4,1985 (50 FR 13456) adjusted reportable quantities for 340 hazardous substances, in a Notice of Proposed Rulemaking (NPRM) also published on April 4.1985. the Agency proposed adjusted RQs tor 105 additional hazardous substances (50 FR 13514). A final rule published on September 29.1986 (51 Ffe 34534) finalized RQ adjustments for 102 of these 105 hazardous substances.1 Currently, there are 717 CERCLA hazardous substances. Twelve of these substances were listed recently under section 3001 of the Resource Conservation and Recovery Act (RCRA) and adjusted RQs are proposed for these twelve substancesjin this rulemaking.* In today's ijulemaking, EPA 1 As noted in that final rule, the Agency decided to retain the atatutory one-pour d RQs for lead, pentschloroethane. and methyl chloride, pending analysis of their potential carci: lOgenicity.

In addition, these adjustments will relieve the regulated community of the burden of reporting releases which are unlikely to pose such threats. The RQ adjustments proposed in this rulemaking will affect not only the statutory one-pound RQs under CERCLA, but also the RQs established pursuant to section 311(b)(4) of the CWA. When there is a release of a hazardous substance in a quantity equal to or greater than Its RQ as listed in 40 CFR 302.4, Table 302.4, as amended in the September 29,1986 final rule (see 51 FR 34534, 34541), the person in charge of the vessel or facility must immediately notify the National Response Center.

Statutory Authority The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (P.L. 96-510), 42 U.S.C. 9601 et seq. (CERCLA or the Act), as amended by the Superfund Amendments and Reauthorization Act of 1986 (Pub. L. 99-499) (SARA), establishes broad federal authority to deal with releases ot threats of releases of hazardous substances from vessels and facilities. Section 101(14) of CERCLA defines the term "hazardous substance" by reference to other environmental statutes. Currently, there are 717 CERCLA hazardous substances. The Administrator of the U.S. Environmental Protection Agency (EPA) may designate additional hazardous substances pursuant to section 102 of CERCLA. Section 103 of the Act requires that the person in charge of a vessel or facility notify the National Response Center immediately when there is a release of a hazardous substance in an amount equal to or greater than the reportable quantity (RQ) for that substance.4 Section 102(b) of CERCLA * A release into the environment of a substance which is not listed es a CERCLA hazardous substance but which rapidly forms a CERCLA hasardoua substance upon release is subject to the notification requirements of section 103.

Section 102(a) authorizes EPA to bdjust all of these RQs by regulation. A major purpose of thei section 103 (a) and (b) notification requirement is to alert the appropriate government officials to releases of hazardous substances that may require a federal response action to proteqt public health and welfare and the environment Under section 104 of CERCLA, the federal government may respond whenever there is a release or a substantial threat of a release into the environment of a hazardous substance. Response activities are to be taken! to the extent practicable, in accordance with the National Contingency Plan (NCP) (40 CFR 300), which was originally developed under the CWA and which has been revised to reflect the responsibilities and authority created by CERCLA. EPA emphasizes that a hazardous substance release notification is merely a trigger for informing the govemmenjt of a release so that appropriate federal personnel can evaluate the need for a federal removal or remedial action and undertake any necessary action in a timely fashion. Federal personnel will evaluate all reported releases, but will not necessarily initiate a rerrioval or remedial action in response to all reported releases, because the release of an RQ of a hazardous supstance will not necessarily pose a hazarp to public health or welfare or the Environment Government personnel will assess each reported release on a caqe-by-case basis lo determine the appropriate action. In certain limited situations! when direct reporting to the National Response Center is not practicable! the person in charge may report to thejnearest Coast Guard- or EPA-predesigitated On-Scene Coordinator (OSC). If it is not possible to notify the National Response Center or predesignated OSC immediately, reports may be made immediately to the nearest Coast Guard unit, provided that the person in charge notifies the National Response Center as soon as possible (40 CFR 300.63(b) and 33 CFR 153.203). Section 103(b) authorizes penalties, including criminal sanctions, for persons in charge of vessels or facilities who fail to report releases of hazardous substances which equal br exceed RQs. Section 109 of SARA ampnds section reaction pnxiuct e>|uals or exceeds the RQ Tor that substance, the release mast be reported lo the National Response Center. 103(b) of CERCLA, increasing the maximum penalties and years of imprisonment. Any person who, as soon as that person has knowledge of a reportable release, fails to report the release immediately pursuant to section 103(b) or who submits any information which he knows to be false or misleading, shall, upon conviction, be fined in accordance with the applicable provisions of Title 18, United States Code (not more than $250,000 or $500,000, depending upon whether the violator is an individual or an organization), or imprisoned for not more than three years (or not more than five years for second and subsequent convictions), or both. Notifications received under section 103(b) or information obtained by exploitation of such notifications cannot be used against any reporting person in any criminal case, except a prosecution for perjury or for giving a false statement. Section 109 of SARA also provides for a system of administrative penalties for violations of CERCLA section 103(b), enforceable through civil proceedings. B. Background ofthis Rulemaking On May 25,1983, EPA proposed a rule (48 FR-23552) to clarify procedures for reporting releases of CERCLA ' hazardous substances and to adjust RQs for 387 of the then 696 CERCLA hazardous substances.6 The May 25, 1983 NPRM also compiled for the first time the list of "hazardous substances" defined under section 101(14) of CERCLA. The NPRM discussed in detail the CERCLA notification provisions (including the persons required to notify the National Response Center of a release, the hazardous substances for which notification is required, the types of releases subject to the notification requirements, and the exemptions from these requirements), the methodology and criteria used to adjust the RQ levels, and the RQ adjustments proposed under section 102 of CERCLA and under section 311 of the CWA, Cn April 4, 1985, EPA promulgated a final rule (50 FR 13456), that clarified reporting procedures and finalized RQ1 1 Since the May 25,1933 NPRM. 21 additional substances have been listed under section 101(14): waste stream F024 under section 3001 of the Resource Conservation and Recovery Act (RCRA) (49 FR $308): coke oven emissions under section 112 of the Clean Air Act (CAA) (49 FR 33530): waste streams F020, F021. F022. F023, F026. F027, and F026 under section 3001 of RCRA (50 FR1976); waste streams Kill. K112. K113. K1H. K115. and K110. o-toluidine and p-toluidine under section 3001 of RCRA (50 FR -42936): waste streams K117, K116, and Kl 36 under section 3001 of RCRA (51 FR 5327): and 2-elhoxyelhanol undeT section 3001 of RCRA (51 FR 6537). adjustments for 340 hazardous substances! including 21 waste streams. The April 4.1985 Federal Register also contained an NPRM proposing RQ adjustments for 105 additional CERCLA hazardous substances, including seven waste streams (50 FR 13511). On September 29,1986, the Agency promulgated a rule (51 FR 34534) that finalized RQ adjustments for 102 of these 105 hazardous substances. - Today's NPRM proposes RQ adjustments for a total of 273 hazardous substances (including 78 waste streams). The RQ adjustments proposed in this rule would amend Table 302.4 of 40 CFR 302.4 and, consistent with 40 CFR 117.3, would apply not only to CERCLA RQs, but also to the RQs established for hazardous substances under section 311(b)(4) of the CWA. Section II of this preamble discusses key issues relating to RQ adjustments and CERCLA notification requirements that are not addressed in this rulemaking. Section 111 discusses the RQ adjustments end the methodology used in making these adjustments, focusing in particular on the methodology for adjusting RQs based on potential carcinogenicity. Section IV addresses RQ adjustments under section 311 of the CWA. Section V provides a summary of the analyses supporting this proposed rule. It is important to note that other provisions of CERCLA may apply even when the statute does not require notification. Therefore, nothing in this rulemaking should be interpreted as reflecting Agency policy or the applicable law with respect to other provisions of the Act. For example, unless specifically exempted under CERCLA, a party responsible for a release is liable for the costs of cleaning up that release and for any natural resource damages caused by the release, even if the release is not subject to the notification requirements of sections 103 (a) and (b). Similarly, proper reporting of a release in accordance with sections 103 (a) and (b) does not preclude liability for cleanup costs. The fact that a release of a hazardous substance is properly reported or that it is not subject to the notification requirements of sections 103 (a) and (b) will not preclude EPA or other government agencies from taking response actions under section 104, seeking reimbursement from responsible parties under section 107, or pursuing an enforcement action against responsible parties under section 106. Note also that this proposed rule does not affect hazardous substance reporting requirements imposed by other SAL 0000/809? 8142 Federal Register / Vol. 52, No. 50 } Monday, March 16, 1987 / Proposed Rules regulations and statutes (except the CWA--see Section IV below). Neither today's NPRM, |the September 29.1986 final rule, nor theiApril 4.1985 final rule addresses the designation under section 102(a) of hazardous substances which are notjdesignated under other statutes listed in CERCLA section 101(14). The Agency has conducted several preliminary economic and technical analyses od this subject, and an Advance Notice of Proposed Rulemaking (ANPRM) (48! FR 23602), published on May 25,1983, invited public comment. Section 302 of the recently enacted SARA legislation requires EPA to publish a Hist of extremely hazardous substances. On November 17,1986, the Agency published this list (51 FR 41570). Because some of the substances on this recently published list are not CEhCLA hazardous substances, EP|A has decided to initiate a proposed ruletnaking under section 102 of CERCLA toldesignate these extremely hazardouk substances as CERCLA hazardous substances, both to better protect public health, welfare, and the environment, andlto promote regulatory consistency. II. Key Issues Not Addressed in This Rule A. Continuous Releases Under sections 103 (a) sjnd (b) of CERCLA, no distinction isf made between episodic and continuous releases. Section 103 (f)(2)L however, sets forth a reduced reporting requirement for certain releases of hazardous substances. Releases may be reported less frequently than under sections 103 (a) and (b) if they ere "continuous," "stable in quantity and rate," and notification haa been given under sections 103 (a) andl (b) "for a period sufficient to establish the continuity, quantity, and regularity" of the release. Notification n^ust still be given "annually, or at such time as there is any statistically significant increase" in the quantity of the hazardous substance being released. [Thus, instead of reporting every release (as it occurs, certain continuous releases may be reported less often. ' In the May 25.1983 proposal, EPA noted that enforcement efforts would be focused on episodic rathei than continuous releases. The Agency presented alternative interpretations of which releases could be included within the continuous release definition, and discussed an ongoing (e.g.j annual) notification scheme for releases initially determined to be within the definition. The Agency received mire than 40 comments in response to the discussion of continuous releases in the May 25, 1983 NPRM. At the present time, EPA is in the process of developing continuous release reporting regulations to clarify this reduced reporting requirement. B. Federally Permitted Releases One of the exemptions from section 103 reporting requirements is for "federally permitted releases." The definition of "federally permitted release" in CERCLA section 101(10) specifically identifies releases permitted under certain other state or federal programs. In the May 25,1983 NPRM. EPA explained its interpretation of each type of release exempted by the definition of "federally permitted release." The Agency received many comments on the scope of the federally permitted release exemption, most of which urged a broad interpretation of one or more of the federally permitted releases. Due to the complexity of the issues involved, the Agency decided to examine further the scope of the federally permitted release exemption. Currently, the Agency is developing a rule clarifying the definition of "federally permitted releases." C. Radionuclide RQs Radionuclides are hazardous substances under CERCLA because they are designated as a hazardous air pollutant under section 112 of the Clean Air Act (CAA). In the preambles to the May 25,1983 NPRM and the April 4, 1905 final rule, the Agency recognized that the statutory RQ of one pound may not be appropriate for radionuclides, but deferred regulatory action to adjust this RQ until the Agency's analysis of radionuclides was completed. The statutory one-pound RQ for radionuclides is proposed for adjustment in a separate NPRM in today's Federal Register. III. Reportable Quantity Adjustments A. Introduction Section 102(b) of CERCLA establishes RQs for releases ofhazardous substances at one pound unless other RQs were established under section 311 of the CWA. For these latter substances, section 102(b) adopts the established CWA RQs. This rulemaking proposes adjustments to the statutory RQs based upon specific scientific and technical criteria that relate to the possibility of harm from the release of a hazardous substance in an RQ. These proposed RQs, therefore, when finally adjusted, will enable the Agency to focus its resources on those releases which are most likely to pose potential threats to public health and welfare ar.d the environment. Such RQ adjustments will also relieve the regulated community and emergency response personnel from the burden of making and responding to reports of releases which are unlikely to pose such threats. This NPRM proposes adjusted RQs for 273 of the 275 hazardous substances not assigned adjusted RQs by either the April 4,1985 final rule or the September 29.1980 final rule. These 273 hazardous substances have been evaluated for potential carcinogenicity and/or chronic toxicity, and the proposed RQ adjustments are based on the results of these evaluations. RQs are also proposed for six of the constituents used to determine the RCRA characteristic of extraction procedure (EP) toxicity.8 The primary purpose of notification is to ensure that persons in charge notify the federal government so that federal personnel can assess the need to respond to the release. The different RQ levels do not reflect a determination that a release of a CERCLA substance will be hazardous at the RQ level and not hazardous below that level. EPA has not made such a determination because the Agency has found that the actual hazard will vary with the unique circumstances of the release, and extensive scientific data and analysis would be necessary to determine the hazard presented by each substance under a number of possible circumstances. Instead, the RQs are designed to be a trigger for notification and reflect the Agency's judgment that the federal government should be notified of certain releases to which a federal response might be necessary. The RQs represent a determination only of possible or potential harm, not that releases of a particular amount of a hazardous substance necessarily will be harmful to public health or welfare or the environment. Many considerations aside from the quantity released affect the government's decision concerning whether and how it should undertake a response action pursuant to the NCP with respect to a particular release. The location of the release, its proximity to drinking water supplies or other valuable resources, the likelihood of exposure or injury to nearby populations, response actions taken by responsible parties, and other factors must be assessed by the federal OSC on a case-by-case basis. The reporting requirement enables the federal* * For a discussion of these six constituents, including their proposed RQs. see Section I1I.D.Z. of this preamble. .-.'liiiili filia 8l - ......... ooo ?Ql 00 t. eral Register / Vol. 52, No. 50 / Monday, March 16. 1937 / Proposed Rules 8143 government to learn When such assessments should be made. Because the CERCLA RQ adjustment methodology is broader than that used pursuant to section sil of the CWA, some of the RQs proposed today are not the same as those initially promulgated under the CWA. The April 4,1985 final rule (50 FR 13456), amended 40 CFR 117.3 to make RQs adjusted under CERCLA the applicable RQs for purposes of CWA section 311. Thus, when finalized, today's proposed RQ adjustments will apply to both CERCLA and the applicable CWA RQs. A person in charge need not report a single release twice in order to satisfy CERCLA and CWA reporting requirements; one report to the National Response Center suffices. B. Summary of the General Methodology Underlying the Reportable Quantity Adjustmen The Agency has wi le discretion in adjusting the statut RQs for hazardous substance. under CERCLA-7 Administrative feast jlity and practicality are impor ant considerations. The Agency's selected methodology for adjxn ting RQs begins with an evaluation of ihe intrinsic physical, chemical, anjd toxicological properties of each hazardous substance. The intrinsic properties examined-- called '`primary criterija**'--are aquatic toxicity, mammalian t >xicity {oral, dermal, and inhalatioi), ignitability, reactivity, chronic tox city, and potential carcinogenicity. The Agency ranks e ich intrinsic property (except pot itial carcinogenicity) on a tve-tier scale, associating a specific range of values on each scale with a par jcular RQ value, This five-tier scale us the five RQ levels of 1,10,100,1 and 5000 pounds, originally established pursuant to CWA section 311 (see 40 CFR Part 117 and 44 FR 50776). For Hazardous substances evaluated or potential carcinogenicity, each iubstance is assigned a hazard ra ing of "high." "medium," or "low. ese hazard rankings correspond lith RQ levels of 1, 10, end 100 pounds, respectively. Each substance receives several tentative RQ values based on its particular properties. The lowesi of all of the 7 As Senate Report No. 848i 98th Congress.

This proposed rule discusses the RQ adjustment methodology based on the primary criterion of potential carcinogenicity. For a more detailed discussion of the other five primary criteria, see the preamble to the May 25, 1983 NPRM (48 FR 23562-23565), the preamble to the April 4,1985 final Rule (50 FR 13456, Section V.D.l), and the Technical Background Document to Support Rulemaking Pursuant to -CERCLA section 102. Volume 1, March 1985, available for inspection at Room LG-100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. After the primary criteria RQs are assigned, substances are further evaluated for their susceptibility to certain degradative processes. These natural degradative processes are biodegradation, hydrolysis, and photolysis (BHP). These processes tend to reduce the relative potential for harm to public health and welfare end the environment of many hazardous substance releases. Subject to the qualifications set forth below, if analysis indicates that an eligible hazardous substance degrades relatively rapidly to form a less harmful substance or compound through one or more of tbe BHP processes when it is released into the environment, the primary criteria RQ for that substance is raised one level on the basis of BHP. The single RQ - assigned to each hazardous substance on the basis of the primary criteria and BHP becomes the adjusted RQ for the substance. Under no circumstances may the RQ for a substance be raised more than one level based on BHP. If hazardous substances have primary criteria RQs already at the maximum assignable level of 5000 pounds or are found to be bioaccumulative. environmentally persistent, highly reactive (or otherwise unusually hazardous), or degradable to more hazardous products, they are not eligible for a one-level RQ increase on (he basis of BHP. In this rulemaking, the Agency has not adjusted RQs for potential carcinogens beyond 100 pounds based on BHP. The Agency, however, solicits comments with supporting data on whether BHP should be used as a basis for raising RQs for potential carcinogens beyond the 100-ponnd level. primary criteria are Bpptied to the more hazardous product rather than to the original substance to determine the tentative RQ values for the original substance. For example, substances known to generate hydrofluoric acid, hydrogen sulfide, or phosphine opon hydrolysis are assigned primary crileria RQs on the basis of these more hazardous degradation products. For a more detailed discussion of (he BHP criteria and their use in combination with the primary criteria, see the preamble to the May 25,1983 NPRM (48 FR 23565), the preamble to the April 4,1985 final rule adjusting reportable quantities (50 FR 13456.

U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. C. Summary of the Methodology for Adjusting the RQs ofPotential Carcinogens 1. Identification Methodology To identify those CERCLA hazardous substances that may be potential carcinogens, EPA reviewed four sources of human epidemiologic and/or animal bioassay data on hazardous substances that suggest possible carcinogenic effect. These sources are: (1) the Annua) Reports on Carcinogens of the National Toxicology Program, U.S. Department of Health and Human Services (DHHS); (2) the Monographs of the International Agency for Research on Cancer (IARC); (3) final Agency determinations published in the Federal Register identifying substances as potential carcinogens; and (4) ongoing determinations by the Agency's Office of Health and Environmental Assessment that substances may be potential carcinogens, based on either published or unpublished data. The Agency compared the list of substances derived from these four sources with the list of the 717 CERCLA hazardous substances to determine which hazardous substances should be evaluated for potential carcinogenicity. Sources 3 and 4 listed above have been recently added to supplement the Agency's screening criteria for identifying potential carcinogens. The Agency currently is in the process of screening for potential carcinogenicity the hazardous substances that received adjusted RQs in the April 4,1985 final rule and the September 29,1986 final rule. Any hazardous substance identified as a potential carcinogen as a result of this review will receive a ranking for potential carcinogenicity, as described below, and may have its RQ readjusted on that basis in a future rulemaking. 2. Ranking Methodology The Agency's Carcinogen Assessment Group (CAG) has developed a method 0007S101 SAL- 0 8144 Fedeial Register / Vol. 52, No. 50 / Monday, March 16, 1967 / Proposed Rules for ranking CERCLA ha rardous substances for potentia carcinogenicity. The CERCLA methodology for evaluating hazardous si bstances for potential carcinogenicit / is set out for public comment for the first time in today's proposal. The vi eight-of- evidence portion of the CERCLA methodology was developed independently of this ru lemaking. as part of the Agency's Prc posed Guidelines for Carcinog en Risk Assessment (49 FR 46284. November 23, 1964). The CERCLA mi thodology is not a risk assessment and It does not yield an absolute measure of harm. Rather, the methodology simply represents a means of sorting potent ally carcinogenic substance: into categories, which may then be equi ted to RQ levels. The methodology for tanking potential carcinogens begins by reviewing available Information in the scientific literature on each substance identified as a potential carcinogen. This information is then evaluated using a two-stage process. The irst stage is a qualitative assessment i >f the likelihood that a particular hazard jus substance is a human carcinogen. Di ring this stage, the available data is ev; lusted using EPA's "weight-of-evidei ice" classification system, pi esented in the Agency's Guidelines fox Carcinogen Risk Assessment. 'Hie s rcond stage is a quantitative assessment designed to predict the relative strei iglh of a hazardous substance to elicit a carcinogenic response (`potency factor"). The quantitath e stage allows the Agency to rank pole dial carcinogens on a numer cal scale by identifying the most pot mt substances as the most hazardous. ` rhe results of the qualitative and quar titative assessments are then ccmbined to arrive at a "hazard ranking" fc r each hazardous substance evaluated for potential carcinogenicit; >. The CAG methodology for rankinj potential carcinogens is discusser in more detail below. 1 During the qualitative! assessment stage, the Agency evaluates the quality and reliability of the available data to determine the "weight of evidence" (or degree of certainty) that] a particular hazardous substance is p human carcinogen. The data usfed are derived primarily from human epidemiology The Final Guidelines for Carcinogen Risk Assessment were signed by thi Administrator on August 22.1986, and published in the Federal Register on September 24.19Sd[|see Si FR 33992). Hie weight-of-evidence methodology contained In the Proposed Guidelines was not changed in the Final Guidelines or In the CERCLA methodology described above. studies and animal bioassay studies, but supportive information such as mutagenicity and chemical structure also is considered. In this process, the degree of evidence in human and animal studies is evaluated separately and classified as "sufficient" evidence, "limited" evidence, "inadequate" evidence, "no data," or "no evidence." The guidelines used for the weight-ofevidence determination follow the Agency's Guidelines for Carcinogen Risk Assessment. These classifications are then combined with supportive evidence to arrive at an overall weightof-evidence category (A, Bl, B2, C, D, or E) representing the degree of certainty that a particular hazardous substance is a human carcinogen. A hazardous substance is placed in Group A (known human carcinogen) only if "sufficient" evidence from human epidemiologic studies supports a causaL connection between exposure to the hazardous substance and cancer. Group B (probable human carcinogen) includes hazardous substances for which the weight of evidence of human carcinogenicity based on epidemiologic studies is "limited," or for which the weight of evidence of carcinogenicity based on animal studies is "sufficient" (in the absence of sufficient human evidence). Group B is divided into two subgroups, Bl and B2. Where there is limited evidence of carcinogenicity from epidemiologic studies, a hazardous substanch usually is placed in Group Bl. Hazardous substances for which there is "sufficient" evidence from animal studies and "inadequate" evidence or "no data" from human epidemiologic studies usually are placed in Group B2. Because it is reasonable to treat hazardous substances for which there is sufficient evidence of carcinogenicity in animals as if they present a carcinogenic risk to humans, such substances are classified as probable human carcinogens (Group B). Group C (possible human carcinogen) includes hazardous substances with "limited" evidence of carcinogenicity in animals and "inadequate evidence" or "no data" from human epidemiologic studies. A hazardous substance is placed in Group D (not classifiable far human carcinogenicity) if there is "inadequate" human and animal evidence of carcinogenicity or no data are available. Group E (evidence of noncarcinogenicity for humans) includes hazardous substances that show no evidence of carcinogenicity in at least two animal tests in different species or in both human epidemiologic and animal studies. The designation of a Group E substance is based on the available evidence and should not be interpreted as a definitive conclusion that the substance will not elicit a carcinogenic response under any circumstances. Group D and E substances are not considered to be "potential carcinogens" for purposes of this proposed rulemaking (see note 11 below). No hazard ranking is made for these substances and other primary criteria are used to assign RQs. During the quantitative stage, the Agency uses the available data to estimate the dose of a hazardous substance associated with a lifetime increased cancer risk of 10 percent (EDio). The estimated doee is then used to calculate a potency factor (F), where F equals l/ED10. The 10 percent lifetime risk is used because this risk level is within the experimental range and does not require additional extrapolation to estimate the carcinogenic response at extremely low doses. Details of the calculation of potency factors for specific hazardous substances evaluated for potential carcinogenicity may be found in the individual chemical profiles for each potential carcinogen. These chemical profiles are available for inspection at Room LG-100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. Based on the calculated potency factors, each potential carcinogen is ranked and then placed in one of three potency groups. Group 1 includes those hazardous substances with the highest potencies. Other potential carcinogens with medium and low potencies are placed in Groups 2 and 3, respectively. Whenever available information allows EPA to quantify potency, a substance is placed in potency Group 1, 2, or 3. However, for certain potential carcinogens, there is either "sufficient" or "limited" evidence of carcinogenic effect, but the quantitative information is not adequate to allow the Agency to estimate a potency factor using the Agency's current methodology. There are two classes of such substances. First, if the best available data indicates that a substance may be a strong carcinogen (i.e., all animals exposed to every experimental dose developed tumors), the Agency will assign the substance to the highest potency group (Group 1). Second, if the best available data are inadequate for calculating a potency factor and allow no quantitative inferences to be made, the substance will be assigned to Group 2, as though it had a mid-range potency factor.10 These >a For similar reasons, asbestos is assigned 10 potency Group 2. Asbestos is a unique case because Coniinued .v ,v r? r: : > -s SAL 000078102 $ Fedei al Register / Vol. 52, No. 50 / Monday, March 16, 1987 / Proposed Rules 8145 assigned potency factoi b enable the Agency to assign bazar* 1 rankings to these substances follow ing the standard procedure of combining the weight-of- evidence group with the potency group, The final step in the hazard ranking procedure is to combine die qualitative weight-of-evidence groi ps and the quantitative potency fa< ;tor groups using a matrix to yield a relat ve hazard ranking for each substa: tee. Thus, hazard rankings are bai ed jointly on two factors--weight of Evidence and potency--that the Agenjcy believes are . important in describing carcinogenic hazards. The three relative rankings are Identified as``high," "m edium," and "low." The matrix is ananged bo that as the weight of evidence t nd the potency factors decrease, the ha sard ranking decreases also. Depending on whethe r a weight-ofevidence Group B carcii iogen falls into potency Groups 1.2, or 1, a hazard ranking of high, mediuir, or low is assigned. Hazard rankii gs are one level higher (high, high, or medium) for weight-of-evidence Groi ip A carcinogens. This incret sed concern is justified because there i i direct human ' evidence establishing tt at Group A substances cause cance \ Hazard rankings are one level lnwer (medium, low, or low] for Group C carcinogens. This reduced concern is justified because of the lack of e' ridence implicating Group C substances as human carcinogens, i.e.J either the available'studies are well-conducted but unrepheated or the evidence is of marginal biological or statistical significance. Before settling on the; e hazard ranking assignments, al emative ranking schemes were consider* d. Proposals that all Group A substances be ranked high or that all Group C substances be ranked low were reject* d because the Agency believes strongly that potency, too. is important in describing a carcinogenic hazard. Similarly, a proposal to base hazard potency alone was rejec ted because the Agency believes that th: weight of evidence must be consit ered as well. The Agency believes thft the hazard scheme finally selected allows proper consideration of both w sight of evidence and potency. For furthei discussion of the hazard ranking matrix, see the Technical Background I ocument to Support Rulemaking Pursuant to CERCLA Section 102, Vblume 3, December 1986, available for inspection at Room LG-100, U.S. Environmental Protection Agency. 401 M Street, SW, Washington, DC 20460. The following is the matrix the Agency used to arrive at hazard rankings: HAZARD RANKING vgioroeunpc* Potency group 1 (higtoci) 2 3 (lowest) HHiigghh____ ------- No hazard ranking is wads. Tha other primary criteria an uaad to Sattgn tha RQ. No hazard ranking n mada. Tha othar primary crilaiia ara uaad to aaaign tha RO. . This grouping of all potential carcinogens11 into "high," "medium," and "low" hazard categories on the basis of biological information is used to assign RQ levels. RQ levels are assigned to the hazard rankings as follows: high-- one-pound RQ: medium--10-pound RQ; and low--100-pound RQ. In deciding whether to assign RQs for potential carcinogens at all five RQ levels, the Agency examined the special properties associated with these substances, used the Agency's air dispersion model to analyze the risks posed by their release, and evaluated them in light of the Agency's chronic toxicity methodology. The Agency decided not to use the two highest RQ levels for potential carcinogens for several Reasons. First, cancer can be considered to be a chronic health effect. EPA therefore believes that reference to the Agency's chronic toxicity methodology is appropriate in assigning RQs to potential parcinogens. Under the chronic toxicity methodology, each substance is assigned two rating values, one based on the dose that causes a particular effect and one based on the severity of the effect. The dose ratings range from one to 10, with 10 representing the most toxic substances. The effect ratings also range from one to 10, with 10 representing the most severe effect. The product of the dose and effect ratings for each substance yields a composite ranking score between one and 100. For a more detailed discussion of the chronic toxicity methodology, see the Technical Background Document to Support Rulemaking Pursuant to CERCLA Section 102, Volume 1, March 1985, available for inspection at Room LG-100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. Because cancer is a life-11 Ithough data are available, th ;#e data are baaed on particle size rather than weigh ao that a relative potency ranking cannot be calculated for asbestos (see discussion in Section lll.D.l of this preamble). 11 For purposes of this proposed rale, the term -potential carcinogens" refers to all hazardous substances assigned to Group A. B. or C under the Agency's weight-of-evidence methodology.- threatening or life-shortening effect, the effect rating for cancer would be 10 if cancer were ranked on the chronic toxicity scale. Therefore, the composite score for any potential carcinogen would be at least 10. A composite score of 10 corresponds to an RQ of 1000 pounds. Thus, a 5000-pound RQ for a potential carcinogen would be inappropriate based on the Agency'9 chronic toxicity scale. Second, application of an air dispersion model developed by the Agency shows that substantial cancer risks can result from releases of 1000 pounds or more of moderate to weak potential carcinogens. The results of the Agency's evaluation using the air dispersion model indicate that reporting levels of 100 pounds or less for potential carcinogens are necessary to protect public health from releases of these hazardous substances. The model is based on an exposure scenario that includes the following release conditions: the substance is a stable gas, volatile liquid, or aerosol that remains in the air long enough to reach the point of exposure, the duration of exposure is 24 hours, the release occurs under stable meteorological conditions (one meter per second wind speed), and exposure occurs 30 meters downwind from the point of release. For a more detailed discussion of the Agency's air dispersion model and the assumptions on which it is based, see the Technical Background Document to Support Rulemaking Pursuant to CERCLA Section 102, Volume 3, December 1986, available for inspection at Room LG- 100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. The Agency haB rejected the use of scenarios for RQ adjustment purposes in previous RQ rulemakings (see 50 FR 13456,13466, April 4,1985). In this proposed rulemaking, however, the Agency has used worst case exposure assumptions in its analysis. The Agency made these assumptions because of uncertainty about the duration, magnitude, and route of future exposures. Because of the factors described below, future exposures to potential carcinogens may be of concern. First, in contrast with other toxic effects, threshold levels of exposure below which a potential carcinogen does not present some risk of cancer have not been demonstrated. Doses that have been Bhown to cause cancer are generally lower than the lowest dose-that induces a chronic effect. The linear non-threshold mechanisms of carcinogenesis contained in the Agency's Guidelines for l! r r I SAL 000078103 l. I 8146 Federal Register / Vol. 52, No. 50 / Monday, March 16, 1987 / Proposed Rules Carcinogen Risk Assessmei it (51 FR 33992) suggest that appropr atelydesigned studies could de nstrate onset of cancer at even lowr doses, Second, cancer risks are co isidered to be cumulative, therefore a i umber of small releases can be as se ious as a single large release. Becauaje the cancer risk depends on the cumulative dose. uncertainties about future Exposures are cause for concern. Future rrleases of the same potential carcinogen 4dd to the risk. Future releases of oth potential carcinogens that cause caner by the same mechanism also add o the risk, Occupational exposures or ambient environmental exposures ii .icrease the risk further. This is in conib__ast to noncancer health effects, for which a number of small exposures below the threshold pose no future rifk. For these reasons, together with the iact that cancer has a latent period that does not allow direct observation of carcinogenic risks from substances newly released into the environment, the :ency proposes to calculate the a; tpropriate maximum RQ level for pot< ntial carcinogens using a model bat is based on conservative assumption Although this proposed rile does not assign 1000-pound or 5000-] >ound RQs to any potential carcinogen, EPA solicits comments with supporting data on whether individual potent!. tl carcinogens should be eligi ble for 1000* pound or 5000-pound RQs because such substances lack the specia' characteristics that disting iish potential carcinogens from other haaiardous substances. At this time, th e Agency does not plan to assign fint 1 adjusted RQs of greater than 1000 ptmds to any potential carcinogen becaujse this result would be inconsistent with the Agency's chronic toxicity methodology discussed above. 3. Changes in Ranking Met lodology In its evaluation of CERCLA hazardous substances ider tified as potential carcinogens, the , Agency initially employed a rankir g methodology that used a weight-ofevidence Bcheme develope i by IARC. EPA subsequently revised :he IARC weight-of-evidence scheme, and used this revised weight-of-evid;nce methodology in conjunctio l with potency factors, to obtain 1 iazard rankings for CERCLA hazardous substances that are potent al carcinogens. The revised r. inking methodology has been sun marized in Section 111.C.2. of this prea nble and is discussed in greater detail in the CAG report entitled `Technical Support Document and Summary Table for the Ranking of Chemicals Based on Carcinogenicity," OHEA-C-073, February 1986. This report is reproduced as Appendix A of the December 19B6 Technical Background Document to Support Rulemaking Pursuant to CERCLA Section 102, Volume 3, available for inspection at Room LG100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington. DC 20460. EPA decided to use the revised weight-of-evidence methodology because the revised methodology refines the IARC approach and has had extensive peer review both within and outside the Agency. In order to distinguish more accurately those substances for which there iB limited evidence of carcinogenicity, but not enough evidence to satisfy Group B requirements, EPA divided IARC Group 3 (insufficient evidence) into Group C (possible human carcinogen) and Group D (not classifiable for carcinogenicity). The revised weight-of-evidence methodology allows Group C substances to be assigned RQs based on potential carcinogenicity. IARC Group 3 substances could not be so assigned. In addition, the Agency's Guidelines for Carcinogen Risk Assessment provide for consideration of certain benign as well a9 malignant tumor data, when appropriate, and pooling of significantly elevated tumor sites and types. Because the RQ adjustment process for this proposed rule wes initiated while the Guidelines still were being developed, the potency factors for some potential carcinogens may not fully reflect the position set forth in the Guidelines regarding consideration of benign tumors and pooling Of tumor sites and types. Therefore, 89 the Agency publishes this proposed rule, we are in the process of verifying that all potency factor calculations are in accordance with the Guidelines. Because many potency factor calculations will not be affected by this review and potency factors would have to change substantially to change hazard rankings, we expect that few, if any, of the substances still undergoing verification will have proposed RQs altered as a result of this review. Therefore, the Agency has decided to proceed now with this proposed rulemaking. The list of substances subject to verification is available for review in the public docket for this rule. This verification process will be completed during the comment period and the resulting chemical profiles and adjusted RQs will be available in the public docket for public review and comment. If necessary, the public comment period will be extended for those substances where reasonable notice and comment time is not available.112113 D. Substances for Which Adjusted RQs are Proposed Today's rule proposes to adjust RQs for 273 of the remaining 275 hazardous substances.18 The proposed RQs lower the statutory RQs of 56 hazardous substances, raise the statutory RQs of 123 hazardous substances, and leave the statutory RQs of 94 hazardous substances unchanged. The 273 hazardous substances include 195 individual hazardous substances and 78 hazardous waste streams. EPA requests comments on the RQ adjustments for particular hazardous substances proposed in this rulemaking, as well as the Agency's methodology for adjusting the RQs for hazardous substances based on potential carcinogenicity. 1. Individual Hazardous Substances The bases for the proposed adjusted RQs of the 195 individual hazardous substances are as fallows: 137 on the basis of potential carcinogenicity alone, 23 on the basis of potential carcinogenicity and at least one other primary criterion, and 35 on the basis of criteria other than potential carcinogenicity.14 *T*h*e following discussion provides an explanation of the proposed RQs for certain individual hazardous substances. Within the 273 hazardous substances (195 individual hazardous substances and 76 hazardous waste streams), subject to today's proposed rule, there are four hazardous substances that were not evaluated for the primary RQ 11 In addition, the Agency haB completed a separate primary review of the RQ profiles for each of the 131 individual hazardous subfiances that have been evaluated for potential carcinogenicity. Currently, the Agency is conducting a secondary level of review of these profiles. The Agency expects that this aecondary review will be completed during the public comment period. If. as a result of this review, reasonable notice and comment lime is not available for particular substances, the public comment period will be extended for those substances. 13 The two substances whose RQa are not adjusted in this rulemaking are being evaluated as follows: methyl isocyanate on the basis of Inhalation toxicity; and lead on the basis of potential carcinogenicity. The statutory one-pound RQs for methyl isocyanate and lead will be retained, pending completion of the Agency's analysis of their toxicity or potential carcinogenicity. * Thirty-one of these 35 substances were identified as potential carcinogens. The proposed RQs for these 31 substances are not based on potential carcinogenicity, however, because their tentative RQs based on potential carcinogenicity..... an higher than the tentative RQs based on other criteria. Four of these 35 substances were not evaluated for potential carcinogenicity (see discussion following in text). 3 SAL 000078104 Federal Register / Vcl. 52, No. 50 / Monday. March 16. 1987 / Proposed Rules 8147 adjustment criterion cf potential carcinogenicity {chloral, hexachlorocyclopentaldiene. 2ethoxyethanol. and pirathion). The proposed RQs for theie four hazardous substances are based on primary criteria other than potential carcinogenicity. Chloral originally vt as identified as a potential carcinogen t ecause it was thought to hydrolyze to chloroform, a potential carcinogen.' rhe May 25,1963 NPRM (48 FR 23552) ii idicated that chloral was to be evaluated for potential carcinogenicity based on its potentially carcinogenic reaction product, chloroform. One comi lent received in response to the May 2 5,1983 NPRM noted, however, that < hloral does not readily hydrolyze. Th< t Agency agrees with this observation, and therefore has decided to base the pi oposed RQ for chloral (5000 pounds) on evaluation of the primary criteria for chloral itself, and not on an evaluat on of the primary criteria for any reactic n products. Parathion and hexa :hlorocyclo- pentadiene have not t een identified as potential carcinogens (orRQ adjustment purposes. The RQs foi both substances are being reproposed; rom the onepound RQs proposed in the May 25,1983 NPRM for both substances on the basis of the primary RQ ad) istment criterion of aquatic toxicity. A i :omment received on the May 25,1983 N JRM cited more recent aquatic toxicitj data using preferred Bpecies. The new aquatic toxicity data support i proposed 10pound RQ for parathic n. Since publication of the Ma; 25,1983 NPRM, the Agency has also obtained additional data on the degradation of hexachlorocyclopentadiene in thi environment. These additional data support raising the previously proposed one-pound RQ for hexachlorocyciopentadiene to 10 pounds based on BHP Finally, 2eihoxyethanol also ha* not been identified as a potenti il carcinogen and its proposed 1000-poui id RQ is based on the primary RQ adjust ment criterion of chronic toxicity. After the most recent rulemaking proposing RQ adjustments (50 FR 13514, April 4,1985), 2- ethoxyethanol was added to the list of CERCLA hazardous substances as a result of its listing as f hazardous waste under section 3001 of 1ICRA (51 FR 6537, February 25,1986). Th trefore, the proposed RQ adjustim mt for 2ethoxyethanol is inclu led in this proposed rule. . Two substances (pe itachloroethane and methyl chloride) f jr which adjusted RQs originally were proposed in the April 4,1985 NPRM (50 FR 13514) have their RQs reproposed for adjustment in today's rule. As noted in the September 29.1986 final rule (51 FR 34534), the statutory one-pound RQs for these two substances were retained, pending analysis of their potential carcinogenicity. That analysis Is now complete and the proposed RQ for methyl chloride is 100 pounds based on -ignitahility and potential carcinogenicity. Pentachloroethane was evaluated for potential carcinogenicity, but received a lower RQ of 10 pounds based on aquatic toxicity. Therefore, the proposed RQ for pentachloroethane is 10 pounds based on aquatic toxicity. In the May 25,1983 NPRM (48 FR 23552), the Agency proposed to lower the RQ for PCBs from the statutory level of 10 pounds (established on the basis of aquatic toxicity data under section 311 ' of the CWA) to one pound, on the basis of other aquatic toxicity data. EPA received 28 comment letters containing 66 total comments, all of which objected to the proposed one-pound RQ for PCBs. The Agency stated in the April 4,1985 final rule that it was evaluating PCBs for .potential carcinogenicity and'would ^retain the 10-pound statutory RQ until that analysis was completed. - The Agency's analysis of PCBs for potential carcinogenicity is now complete, and that analysis has yielded a hazard ranking of "medium," corresponding to a 10-pound RQ. However, based on a re-examination of all of the comments received on the appropriate RQ for PCBs in response to the May 25,1983 proposal and a re- evaluation of all available aquatic toxicity data concerning PCBs. the Agency has decided to repropose a onepound RQ for PCBs in this rulemaking, based on aquatic toxicity. The Agency's current methodology for adjusting RQs based on aquatic toxicity favors use of data from tests using adult life stages. However, use of data from tests using juvenile life stages is appropriate for adjusting the RQ for PCBs because PCBs bioaccumulate, are insoluble, and are sinkers. Because of the combined effect of these chemical and physical properties. PCBs pose a particular threat to benthic organisms (including the early life stages of many aquatic species). The Agency used early life stage data to support the original proposed one-pound RQ for PCBs in the May 25,1983 NPRM. As mentioned earlier, EPA received extensive ' comments opposing a one-pound RQ for PCBs. None of these comments, however, objected to the Agency's reliance on early life stage data. In addition, use of such data is entirely consistent with EPA's 1985 Guidelines for Deriving Numerical National Water Quality-Criteria for the Protection of Aquatic Organisms and Their Uses. Available aquatic toxicity data from tests using early life stages supports a one-pound RQ for PCBs. Available data from tests using adult life stages supports a 10-pound RQ for PCBs. The Agency has decided that where both early life stage and adult life stage data are available for substances that are bioaccumulative insoluble sinkers, the early life'stage data will be preferred because this approach is consistent with the Agency's 1985 National Water Quality Guidelines mentioned above. For further information on the substances EPA has identified as bioaccumulative insoluble sinkers, see the Technical Background Document to Support Rulemaking Pursuant to CERCLA Section 102, Volume 3, December 1986, available for inspection at Room LG-100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460. Thus, EPA reproposes to adjust the 10pound statutory RQ for PCBs to one pound in today's rule. The Agency solicits comments on the proposed onepound RQ for PCBs as well as the possible future revision of the aquatic toxicity methodology to provide for use of early life stage data for hazardous substances (such as PCBs) that are bioaccumulative insoluble sinkers. Asbestos has been identified as a known human carcinogen (weight-ofevidence Group A). However, exposure to asbestos is measured by calculating the size and number of airborne fibers, and not by the standard method of measuring quantitative exposure to potential carcinogens based on weight, volume, or concentration. Therefore, a numerical potency factor based on weight cannot be calculated for asbestos to achieve a direct potency ranking. Thus. EPA has assigned asbestos to potency Group 2, as though it had a mid range potency factor. Using the Agency's matrix for ranking potential carcinogens, a substance in weight-ofevidence Group A and potency Group 2 receives a high hazard ranking, and thus e one-pound RQ. EPA is, therefore, proposing a one-pound RQ for asbestos. For three hazardous substances evaluated for potential carcinogenicity (cacodylic acid, dichlorophenylarsine, and diethylarsine), CAG found no evidence demonstrating that these substances themselves cause cancer. However, because each of these three hazardous substances can and will degrade to arsenic trioxide and arsenic pentoxide (both of which are potential carcinogens) when released into the environment, the Agency haB decided to SAL 000078105 8148 Federal Register / Vol. 52, No. 50 / Monday, March 16, 1987 / Proposed Rules propose a one-pound RQ fo each substance, based an the on4-pound RQs for these two inorganic arse nic oxides. The proposed RQs for cacoi l>; ylic acid, dichlorophenylarsine. and c|iethylar8ine are consistent with the Age lcy's established methodology of| basing the RQ of a substance on its me re hazardous degradation prot.ucts, where those degradation products"have been identified. As discussed in Section I LB. above, hazardous substances are e ligible for a one-level RQ increase on tl e basis of BHP. For five hazardous BU >stances identified as potential careinogens (bis(chloromethyl)ether, ch oromethyl methyl ether, dimethyl sulfi te, formaldehyde, and 2-napht ilylamine), sufficient data are availabls to justify a one-level RQ increase base i on BHP. Therefore, the RQs of these five hazardous substances are Increased to 10,10,100,100, and 10 pour ds, respectively (these increase s are from the one-level lower primarj criteria RQs). In addition, one potential carcinogen, sulfur selenide, hydrolyzes to form two hazardous reaction product s, hydrogen sulfide and selenium dioxid1e. The RQ for hydrogen sulfide is 100 lounds and the RQ for selenium dioxid is 10 pounds. Therefore, a 10-poi|md RQ is proposed for sulfur selenidfe based on the lower RQ of its two rea :tion products. Another potentia carcinogen, 3,3'-dichlorobenzidine, is sObject to rapid photolysis if released into the environment, yielding beiuidine as one of the photolysis products, Therefore, although the CAG methodcjlogy yields a "medium" ranking (10-poui d RQ) for 3,3'-dichlorobenzidine, the Agency is proposing a one-pound RQ for this hazardous substance, base i on the "high" hazard ranking (one -pound RQ) for its photolysis product, 1 enzidine. 2. Hazardous Waste Streai is In addition to the 195 inc ividual hazardous substances for which this rulemaking proposes adjusted RQs, the Agency also proposes to adjust the RQs for 78 hazardous waste str tams. The proposed RQ for each hazs rdous waste stream is the lowest RQ as;ociated with the individual hazardous c jnstituents of the waste stream. Howeve under 40 CFR 302.6, if a person in rge knows of the percentage composii ion of a waste stream, the CWA m xture rule may be applied. The CWA mixture rule provides that "[djischarge: of mixtures and solutions are subject [regulation] only where a component zardous substance of the mixture solution is discharged in a quantity e 4ual to or greater than its RQ" (44 FI 50767, August 29,1979). A8 explained in the April 4,1985 final rule (50 FR 13463), the RQs for different hazardous substances are not additive under the mixture rule, so that the release of a mixture containing half an RQ of one hazardous substance and half an RQ of another hazardous substance does not trigger the CERCLA section 103 reporting requirements. The RQs for the 76 hazardous waste streams for which today's rule proposes adjusted RQs are all currently at the statutory one-pound level. The proposed adjustments leave the RQs of 44 hazardous waste streams at one pound, raise the RQs of 32 hazardous waste Btreams to 10 pounds, and raise the RQs of two hazardous waste streams to 100 pounds. Today's rule also proposes RQs for six of the constituents used to determine the RCRA characteristic of EP toxicity for unlisted hazardous wastes. These six components have been assigned proposed RQs as follows: one pound for arsenic and chromium and 10 pounds for cadmium, all on the basis of potential carcinogenicity; 100 pounds for lead on the basis of chronic toxicity; and one pound for lindane and toxaphene on the basis of aquatic toxicity. Under 40 CFR 302.5(b), the proposed RQ applies to the unlisted waste itself, not merely to the toxic substance. The RQ for the metal constituents is based on the RQ for soluble metal salts, and not the metal itself. 1 IV. Reportable Quantity Adjustments Under Section 311 of the Clean Water Act The April 4, 1985 final rule (50 FR 13456) amended 40 CFR 117.3 to make RQs adjusted under CERCLA the applicable RQs for notification of discharges of hazardous substances pursuant to CWA section 311. Thus, the RQ adjustments proposed in this rulemaking will, when finalized, apply to both CERCLA and CWA section 311 RQs. Of the 195 individual hazardous substances in this rulemaking, 63 were originally listed as hazardous substances and assigned RQs under section 311 of the CWA. The proposed RQs lower the statutory CWA RQs of 49 of these substances, raise the statutory RQs of two of the substances, and leave the RQs of 12 of the substances at the statutory level. RQs under both CERCLA and the CWA are set forth in Table 302.4. Where there is a release of a hazardous substance in an RQ into navigable waters, a single report to the National Response Center by the person in charge will satisfy the notification requirements of both statutes. For further discussion of the relationship between CERCLA RQs and CWA section 311 RQs. see the May 25,1983 proposed rule preamble at 48 FR 23569. and the April 4,1965 final rule preamble at 50 FR 13473. V. Summary of Supporting Analyses Executive Order 12291 requires that regulations be classified as major or non-major for purposes of review by the Office of Management and Budget (OMB). According to E.0.12291, major rules are regulations that are likely to result in: (1) An annual effect on the economy of $100 million or more; or (2) A major increase in costs or prices for consumers, individual industries, federal, state, or local government agencies, or geographic regions; or (3) Significant adverse effects on competition, employment, investment, productivity,, innovation, or on the ability of United States-based enterprises to compete with foreignbased enterprises in domestic or export markets. An economic analysis performed by the Agency, available for inspection at Room LG-100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460, shows that today's proposed rule is non-major, because the rule will result in net costs of approximately $3.9 million annually. The annual net cost savings of RQ adjustments made to date (including those proposed in this NPRM) is $13.8 million. It should be noted that these costs and cost savings reflect only those effects of the RQ adjustments that are readily quantifiable in dollars. The Regulatory Flexibility Act of 1980 requires that a Regulatory Flexibility Analysis be performed for all rule9 that are likely to have a "significant impact on a substantial number of small entities." To determine whether a Regulatory Flexibility Analysis is necessary for today's proposed rule, a preliminary analysis was conducted using a computer model that simulated the typical operation of a small U.S. chemical company. The results of the simulation indicate that the upper-bound total cost of compliance to small firms is negligible. See the Regulatory Impact Analysis of Reportable Quantity Adjustments Under Sections 102 and 103 of the Comprehensive Environmental Response, Compensation, and Liability Act, Volume III, November 1966, available for inspection at Room LG100, U.S. Environmental Protection Agency, 401 M Street, SW, Washington, DC 20480. Therefore, because today's proposed rule is not expected to have a significant impact on small entities, EPA 000078106 SAL Fed* ral Register / Vol. 52, No. 50 / Monday, March 16, 1987 / Proposed Rules 6149 certifies that no Regulj .tory Flexibility Analysis is necessary. The Information Imi act Analysis performed for the Apri I 4,1985 final rule indicated that that fmi 1 rule would decrease the paperwo{k burden imposed on parties other than A by about 50.000 hours. Today's ; iroposed RQ adjustments will provi d e a small increase in the papers ork burden imposed on the regula ed community for information collection associated with reporting releases. Bedause the effect of this proposed rule on 1 he paperwork burden is minimal, EP. t has determined that no further Inform; ition Impact Analysis need be perfprmed. In accordance with he Paperwork Reduction Act of 1960 44 U.S.C. 3501 et seg^ the reporting or rfecordkeeping provisions that are inieluded in this proposed rule have b'een submitted for approval to OMB undir section 3504(h) of the Paperwork Redjiction Act Any final rule will include m explanation of how the reporting or r jeordkeeping provisions contained ! herein respond to any comments by OM3 and the public.

Lee M. Thomas, Administrator. For the reasons set out in the preamble, it is proposed to amend Title 40 of the Code of Federal Regulations as follows: PART 302--DESIGNATION, REPORTABLE QUANTITES AND NOTIFICATION 1. The authority citation for Part 302 is revised to read as follows: Authority: Sec. 102 of the Comprehensive Environmental Response. Compensation, and Liability Act of 1980, as amended, 42 U.S.C. 9602: Secs. 311 and 501(a) of the Federal Water Pollution Control Act, 33 U.S.C. 1321 and 1361. 2. Section 302.4 is amended by revising the following entries in Table 302.4 and in its Appendix A to read as set forth below. The note preceding Table 302.4 is republished without change. Note--The numbers under the column headed "CASRN" are the Chemical Abstracts Service Registry Numbers for each hazardous substance. Other names by which each hazardous substance is identified in other statutes and their implementing regulations are provided in the "Regulatory Synonyms" column. The "Statutory RQ" column lists the RQs for hazardous substances established by section 102 of CERCLA- The "Statutory Code" cohrnrn indicates the statutory source for designating each substance as a CERCLA hazardous substance: "1" indicates that the statutory source is section 311(b)(4) of the Clean Water Act "2" indicates that the source is section 307(a) of the Clean Water Act, "3" indicates that the source is section 112 of the Clean Air Act and "4" indicates that the source is RCRA section 3001. The "RCRA Waste Number" column provides the waste identification numbers assigned to various substances by RCRA regulations. The column headed "Category" lists the code letters "X". "A". "B", "C", and "D", which are associated with reportable quantities of 1,10. 100,1000. and 5000 pounds, respectively. The "Pounds (kg)" column provides the proposed reportable quantity adjustment for each hazardous substance in pounds and kilograms. 7 ABLE 302.4 LIST OF HAZARDOUS SUBSTANCES AND REPORTABLE QUANTITIES \.

G. Grumbles Interoffice Communication FROM: DATE: SUBJ: Michele M. Goodreau January 24, 1986 HAZARDOUS MATERIALS DESCRIPTIONS VIS1A Hazardous material descriptions, for the products manufactured at Hammond, have been reviewed for compliance with current Hazardous Material^ Transportation (HMT) regulations. Based on this review, the desc riptions should be updated. Proposed descriptions and justif ic.i tions for the revisions are summarized below: SA-597 S-ilfonic Acid Current: Proposed RQ, Dodecylbenzenesulfonic acid. Corrosive Material, NA2584. [placarded ''Corrosive*'] Corrosive Liquid, N.O.S., Corrosive Material, UN1760, RQ dodecylbenzenesulfonic acid. [placarded "Corrosive"] SA-597 U s most appropriately described as a corrosive mixture of alkybenz me sulfonic acids, containing approximately 25% dodecylb snzenesulfonic acid and less than 2% free sulfuric acid, Dodecylb anzene sulfonic . acid is a hazardous substance under Superfunji , and packages containing more than the reportable quantity (RQ), ii this case 1000 pounds, must have it indicated on the shipping papers to allow for quick reporting by emergency response personnel Under IA| IA and International regulations, use of the ID number 2584 indicate s that the material contains greater than 5% free sulfuric acid and Packing Group II must be used. Packing group II materials are subj ect to additional restrictions and requirements. Materials containi ng less than 5% free sulfuric acid, as is the case for SA-597, may use packing group III, which is the most appropriate, and leas t restrictive packing group. SA-697 Current: RQ, Dodecylbenzenesulfonic acid. Corrosive Material, NA2584. [Placarded ''Corrosive"] Proposed Corrosive Liquid, N.O.S., Corrosive Material, UN1760. [Placarded "Corrosive"] SA-697 s most appropriately described as a corrosive mixture of alkylben zene sulfonic acids, containing no dodecylbenzene sulfonic acid anc less than 2% free sulfuric acid. The current description could le ad to unnecessary Superfund reporting. Use of the ID number 2584 is also inappropriate, as discussed under SA-597, and imposes addition al restrictions and requirements on shipments. 0000781 32 T..G. Gru nbles Page 2 January 2 4, 1986 C-550, C- 560 Current: RQ, Sodium dodecylbenzenesulfonate, ORM-E, NA9146. Proposed: Hazardous Substance, liquid, N.O.S., ORM-E, NA-9188, RQ sodium dodecylbenzensulfonate. C-550 an 1 C-560 are most appropriately described as a mixture contain!ng 50-60% sodium alkylbenzene sulfonate (SAS). Of the total quantity of SAS, approximately 25% is sodium dodecyl benzene sulfonate Even though these products do not meet the definition of any HMT hazard class, they are still regulated as hazardous substanceis when they contain greater than the reportable quantity (RQ) of a hazardous material. In this case, greater than 1000 pounds o : sodium dodecylbenzene sulfonate. If they contain less than the RQ, they are not regulated for transportation purposes. Please gi ve me your input on this matter as soon as possible. Thanks, JkJ&tydLA. Y*n. -m M. M, Goo dreau ajo/1 SAL 000073133
