of Intent to Delete was'April 12, 1996.
EPA received no comments.
  The EPA identifies sites which appear
to present a significant risk to public
health, welfare, or the environment and
it maintains the NPL  as the list of those
sites. Sites on the NPL may be the
subject of Hazardous Substance
Response Trust Fund-financed remedial
actions. Any site deleted from the NPL
remains eligible for Fund-financed
remedial actions in the unlikely event
that conditions at the site warrant such
action. Section 300.425 (e) (3) of the NCP
states that Fund-financed actions may
be taken at sites deleted from the NPL
in the unlikely event that conditions at
the site warrant such action. Deletion of
a site from the NPL does not affect
responsible party liability or impede
Agency efforts to recover costs
associated with response efforts.

ACTION: Final rule!'

SUMMARY: Today, EPA is implementing
one of its regulatory reform
-commitments set forth in its June 1,
 1995, Report to the President. EPA is
taking final action on two proposed
rules that modify the extremely .
hazardous substances (EHS) list and
reportable quantities under section 302

Federal  Register / Vol. 61, No.  897 Tuesday, May 7, 1996 / Rules and Regulations
' (EPCRA). Title III of the Superfund
 Amendments and Reauthorization Act
 of 1986. EPA is raising the statutory
 reportable quantities (RQs) for 202
 EHSs. EPA is also removing four
 chemicals that do not meet the listing
 criteria from the EHS list. Through these
 actions, the Agency is reducing the
 burden of reporting for facilities
 presently required to report certain
 releases unnecessarily. Protection of
 human health and the environment is
 maintained while better focusing
 attention on releases that may require a
 response by state and/or local
 authorities.

                            This regulation is issued under
                          sections 302, 304. and 328 of the

                          Right-to-Know Act (EPCRA).

                          b. Background                 ,
                            On October 17, 1986, the President
                          signed into law the Superfund
                          Amendments and Reauthorization Act
                          of 1986 (SARA), Pub. L. 99-499 (1986).
                          Title III of SARA, the Emergency
                          Planning and Community Right-to-
                          Know Act of 1986 (EPCRA), established
                          a program designed to encourage state
                          and local planning and preparedness for
                          spills or releases of extremely hazardous
                          substances and to provide the public
                          and -local governments with information
                          concerning chemical releases and the
                          potential chemical risks in their
                          communities.        ,    '
                           ( Subtitle A of the Act establishes the
                          framework for local emergency
                          planning. Under section 302, a facility
                          which has present an extremely
                          hazardous substance (EHS) in excess of
                          its threshold  planning quantity (TPQ)
                          must notify its state emergency response
                          commission (SERC) and participate, as
                          necessary, with the local emergency
                          planning committee  (LEPC) in the local
                          emergency planning process.
                            Section 302 directed EPA to publish
                          the list of extremely hazardous
                          substances as an interim final rule
                          within 30 days of the enactment of
 EPCRA. Section 302(a)(2) required that
 the list be identical to the list compiled
 by EPA in 1985 as part of EPA's
 Chemical Emergency Preparedness
 Program. Under section 302 (a) (4), EPA
 is authorized to revise the list, but in
 Undertaking any such revision, EPA
 must take into account the "toxicity,
 reactivity, volatility, dispersibility,
 combustibility, ,or flammability of a
 substance." The term "toxicity" is
 defined to include "any short- or long-
 term health effects which may result
 from a short-term exposure to the
 substance."
   EPA published the list of 402
 extremely hazardous substances on ,
 November 17, 1986 (51 FR 41570). On
 the same day, EPA proposed the
 deletion of 40 substances from the EHS
 list on the basis that their original listing
 was in error. On April 22, 1987, 52 FR
 13388, EPA announced that it was
 deferring the proposed delisting of these
 substances, pending an evaluation of the
 long-term effects from short-term
 exposure to each of them. This deferral
 was in response to comments from
 members of the public who  argued that
 the proposed rule was premature. On
 November 23, 1987, the District Court
 for the District of Columbia  in A.L.
 Laboratories, Inc. v. Environmental
 Protection Agency issued an order
 requiring EPA to remove several
 substances from the EHS list, reasoning
 that Congress did not intend to include"
 in the statutorily designated list
 substances listed due to "clerical error."

-------
20476      Federal Register / Vol.  61.  No. 89 / Tuesday. May 7.  1996 / Rules and Regulations
d. Alternative Chosen         ,
  In the proposed rule of August 30,
1989, the Agency was-seeking comment
on the various alternatives that could be
used to set the reportable quantities. At
the time the RQ adjustments were
proposed, the Agency anticipated that
the EHSs would be designated CERCLA
hazardous substances as proposed on
January 23, 1989 (54 FR 3388). The
Agency, however is not finalizing at this
time the proposal to designate these
chemicals as CERCLA hazardous
substances. Today's rule does not affect
any CERCLA hazardous substances.
Therefore, the Agency is not utilizing or "
modifying the CERCLA RQ
methodology at this time. Instead, the
Agency has decided to adjust the 1
pound EHS RQs to the same level as
their respective TPQs.2
  The Agency believes that it is
appropriate to rely on the TPQ
methodology rather than the CERCLA   ';
methodology to adjust EHS RQs for
several reasons.
  First, reporting of EHS releases is
required because EHSs are acutely toxic
and will potentially pose an immediate
hazard upon release, Thus, EHS RQs
should be adjusted based on substances'
potential for immediate effects. The
TPQ methodology, designed specifically
for the EHSs, is based on such effects,
utilizing a "level of concern" based
upon short-term exposure
concentrations'that could lead to serious
irreversible health effects.
  Second, use of the CERCLA secondary
criteria of BHP is inappropriate for
adjusting EHS RQs. The BHP analysis is
used to increase a substance's RQ by.
taking into account its natural chemical
degradation. EHSs can cause severe  .
health effects after only a single, brief
exposure which may occur prior to any
chemical degradation. The BHP analysis
a'nd higher RQs based on chemical
degradation are not suitable in this
context.
  Third, as with RQs, the Agency
adjusts TPQs based on the possibility of
harm from the release of a specific
substance. In the Threshold Planning
Quantity Technical Support Document
to the proposed'rule of November 17,
 1986 (51 FR 41570) to adjust TPQs, EPA
stated that the TPQ should represent, a
quantity that could cause serious health
consequences if an accident were to
occur with that quantity. Consistent
with this statement, EPA modelled a
variety of release scenarios to generate
the relative ranking of each EHS and to
  2 The release of EHSs which are already CERCLA
 hazardous substances is reportable at the RQ levels
 applicable under CERCLA. (EPCRA section 304
determine the six TPQ quantities (1, 10,
100, 500, 1,000, arid 10,000 pounds).
Since the TPQ methodology is based on
the possibility of harm from release, the
Agency believes that it is-appropriate to
rely on it to adjust RQs as well.
  Finally, like CERCLA RQs, EPCRA
RQs do not reflect a determination that
a release of a substance will always be
hazardous at the RQ level and never
hazardous below that level. EPA has not
attempted to make such a determination
because the actual hazard will vary with
the unique circumstances of the release.
For this reason, EPA encourages SERCs
and LEPCs to consider the RQ during
their emergency planning process
involving facilities with extremely
hazardous substances.

III. Response to Comments on August
30, 1989 Proposal  ,
  Many of the comments received in
response to the Federal Register notice
of August 30, 1989, are not addressed
today because they concerned the1
designation of EHSs as CERCLA
hazardous substances and the
adjustment of RQs for those substances
under CERCLA. As stated above, the
Agency is not taking action on
modifying the CERCLA RQ
.methodology or listing EHSs as CERCLA
hazardous substances at this time. For a
complete list of comments and the
Agency's responses, see the responses to
comments document in the Docket of
this Federal Register notice.
a. Threshold Planning Quantity
Methodology
  The Agency received several
comments on its proposed use of the
TPQ methodology to adjust RQs. These-
commenters believed that the use of the
TPQ methodology was inappropriate
because the RQ and the TPQ address
different\regulatpry requirements.
  EPA believes that the TPQ
methodology is appropriate for these
chemicals. Although the RQs and TPQs
trigger two distinct notification
requirements, bpth quantities are
adjusted based on the possibility of
harm from the release of a specific
substance. Thus, even though TPQ
 (EPCRA § 302) notification is not
triggered by an actual release, the TPQ
 is based upon the potential harm from
 an actual release. In addition, the
 particular concern-with EHSs is that
 they will potentially pose an immediate
 hazard upon release. Notification
 requirements should be based on the- .
 potential for_these immediate effects,
 and the TPQ methodology (developed
 specifically for the EHS list) is in fact
 based upon the potential for immediate
 effects. For these reasons, the Agency
 believes that the use of the TPQ
 methodology is appropriate to set RQs
 for extremely hazardous substances.
 However, because these  chemicals are
 not being added to the CERCLA
 hazardous substance list, modification
 of the CERCLA RQ methodology is not
 warranted at this time.

 b. Sulfur Dioxide
  The adjusted RQ for sulfur dioxide
 was proposed at 100-pounds. Several
 commenters from the petroleum
 industry commented that the 100-pound
 RQ is.too  low and would require
 needless and excessive reporting for the
 petroleum sector; In the  petroleum
 sector, sulfur dioxide is a combustion
 product created when hydrogen sulfide
 from crude oil and natural gas is flared.
 The commenters referenced the Federal
 Clean Air Act New Source Performance
 Standards that they state allow coal
 fired power plants to emit 200.000
 pounds per day of sulfur dioxide.
  The proposed RQ for sulfur dioxide
 was set at 100-pourtds based on the
 proposed  modified CERCLA RQ
 methodology. In the final rule of April
 22, 1987 (52 FR 13378), the TPQ for
 sulfur dioxide was adjusted to 500-
 pounds. Because there is no 500-pound
.CERCLA RQ level, the sulfur dioxide
 RQ was proposed at 100-pounds. As
 stated earlier in this rule, EPA is not
 modifying the CERCLA RQ
 methodology.at this time, but is
 adjusting  RQs to the TPQ level. The
 final EPCRA RQ for sulfur dioxide is
 500-pounds.                -    ,
  EPA does not agree that the existence
 of a 200,000 pounds per  day standard
 for one sector means that the EPCRA RQ
 should be set at a higher RQ level.
 Sulfur dioxide is used in many
 industries other than the petroleum
 sector, for example, sulfuric acid
 production, water purification and the
 pulp and  paper industry. While flares
 and stacks are designed to lift the sulfur
 dioxide into the:atmosphere, ground
 level releases of sulfur dioxide,
 including releases from containers
 storing sulfur dioxide may be more
 hazardous to the community. Since EPA
 sets one RQ to incorporate all probable
 release scenarios, EPA believes that the
 500 pound RQ based on the substance's
 IDLH value provides an appropriate
 level.
   EPA notes that the release reporting
 requirements of EPCRA section 304
 work in conjunction with the federally
 permitted release exemption under
 CERCLA section 101(10) and the
 continuous release reporting  '      .
 requirements under CERCLA Section
 103. Releases that are federally
 permitted and those that are continuous

-------
             Federal  Register  /  Vol. 61.-'No. 89 / Tuesday.  May 7,  1996  /  Rules and Regulations    '  20475.
It is on the basis of this ruling that EPA
proposed on October 12, 1994 (59 FR
51816), the removal of four chemicals.
  Section  304 of EPCRA establishes
requirements for immediate reporting of
certain releases of EHSs and hazardous
substances (HSs) listed under the
Comprehensive Environmental
Response, Compensation, and Liability
Act (CERCLA) to SERCs and LEPCs,
similar to the release reporting
provisions of CERCLA section 103.
Although similar. CERCLA section 103
and EPCRA section 304 differ somewhat
In purpose. CERCLA provides generally
for federal planning and coordination of
entities and for federal contingency
plans. CERCLA section 103 requires
federal notification for any release of a
hazardous substance in an amount equal
to or in excess of its RQ.  EPCRA is
designed to protect the public in the
event of dangerous chemical releases
through the establishment of local and
state emergency response capability.
EPCRA section 304 requires, in addition
to any federal notification, notification
to state and local authorities for any
release of an EHS in an amount equal
to or In excess of its RQ.  The potential
hazards posed by EHSs make state and
local notification critical to effective and
timely emergency response. EHSs are
acutely toxic chemicals which cause
both severe sort- and long-term health
effects after a single, brief exposure. In
many cases, local and state authorities
may be the first and only responders to
the release of an EHS.
  Notifications are required if a release
of an EHS or HS is equal to or above the
reportable quantity (RQ). Section 304(a)
of EPCRA provides that chemicals on
the EHS list which do not have an RQ
assigned to them by regulation, will
have a reportable quantity of 1 pound.
Currently. 204 EHSs have the statutory
one-pound RQ. On August 30, 1989 (54
FR 35988). EPA proposed to modify the
statutory RQs for 232 EHSs using a
proposed  modification of the CERCLA
RQ methodology.
c. Today's Rulemaking
  EPA is today taking final action on the
two proposed rules published in the
Federal Register on August 30, 1989
and October 12, 1994. As discussed
below, EPA is not yet taking final action
on some aspects of the proposed rules.
EPA is adjusting the reportable
quantities of 204 extremely hazardous
substances.1 This rule will make the
  1 Although a total of 215 EHSs have one-pound
 statutory RQs. this rule Is adjusting the RQs of 204
 of these EHSs. The remaining 11 EHSs with one-
 pound statutory RQs were designated CERCLA
 hazardous substances In a February 9. 1995 final
 rule (60 FR 7824): the Agency is currently
reportable quantities for these chemicals
the same as their threshold planning
quantities. EPA is also finalizing the
proposal to remove phosphorus .
pentoxide, diethylcarbamazine citrate,
fenitrothion and tellurium from the EHS
list.
  On August 30,  1989, EPA proposed
the adjustment of the TPQ for
isophorone diisocyahate. Today's rule
reflects the current TPQ for isophorone
diisocyanate. However, an adjusted TPQ
and RQ will be published in a future
notice.
II. RQ Adjustment Methodologies
a. TPQ Methodology
  EPA's methodology for establishing
threshold planning quantities for EHSs
under EPCRA consists of initially  -
determining the minimum short term
exposure concentration in air that  ;
would lead to serious irreversible health.
effects in the general population when
exposed to the substance for relatively
short duration. This is the so-called
"level of concern." (See the Threshold
Planning Quantities Technical Support
Document, April 7. 1987.)
  There are two ways to determine a
"level of concern." If it is available for
a chemical, EPA may use one-tenth of
the Immediately Dangerous to Life and
Health (IDLH) level established by the
National Institute for Occupational
Safety and Health (NIOSH). The IDLH is
the maximum concentration of a
substance in air to which a healthy '
worker can be exposed for 30 minutes
and escape without suffering
irreversible health effects or impairing
symptoms.' If the IDLH value is not
available, as is the case for most of the
EHSs. EPA determines an IDLH
equivalent value using available toxicity
data with an adjustment factor.
  The level of concern is then divided
by a factor "V" which represents the
extent to which the material can
volatilize and become airborne and
dispersed. This approach is explained-
in the November 17, 1986 Federal
Register notice (51 FR 41580). Dividing
the level of concern by "V" provides the
index value for an EHS-
  The  final threshold planning quantity
is then determined by a relative ranking
of the index values for all of the
chemicals on the EHS list. The index
values and their corresponding
threshold planning quantities are found
in the Threshold Planning Quantity
Technical Support Document. This
.approach is generally based on the
 developing a rulemaking to adjust the CERCLA and
 EPCRA one-pound RQs for these 11 substances. The
 substances are identified in 40 CFR fart 355 by the
 footnote "d."
 quantity of the chemical which when
 released will generate the level of
 concern at a distance of 100 meters.

 b. CERCLA RQ Methodology

   The CERCLA RQ methodology uses a
 two step process to determine the
 possibility of harm from the release of
 a hazardous substance. The
 methodology begins with an evaluation
 of six intrinsic physical, chemical, and
 lexicological properties associated with
 each hazardous substance. These
 properties are known as the "primary
 criteria." Each substance is evaluated
 according to the applicable "primary
 criteria," and an RQ value is determined
 for each applicable criterion. The
 "primary criteria" RQ for each
 hazardous substance is the lowest value
 of all the applicable criteria. For
 example, if the Agency evaluates
 hazardous substance A under the RQ
,adjustment methodology, identifies both
 aquatic toxicity and mammalian toxicity
 data on the substancei and sets a
 tentative RQ of 100 pounds on the basis .
 of aquatic toxicity and 1000 pounds on
 the basis of mammalian toxicity, the 100
 pound value will be the applicable .
 "primary criteria" RQ. Upon completion
 of the evaluation of the "primary
 criteria" RQ, secondary adjustment
 criteria based on the natural degradation
 processes of BHP (biodegradation,
 hydrolysis, and photolysis) are assessed.
 If a' hazardous substance, when released
 into the environment, degrades (within
 5 days) to a less hazardous form by one
 or more of the BHP processes, its
 primary criteria RQ is raised one  level;
 if the substance degrades to a more
 hazardous form, its, RQ may be lowered.

 c. Proposed Methodology

   For approximately 60 of the 232
 chemicals proposed for adjustment on
 August 30, 1989, the CERCLA
 methodology adjusted RQs that were too
, high for purposes of emergency
 notification under EPCRA. The     '
 reportable quantities under the CERCLA
 methodology in these cases are higher
 than the substances' EPCRA threshold
 planning quantity. To rectify this
 discrepancy, the August 30, 1989, notice
 oroposed to modify the CERCLA RQ
 methodology- by integrating the TPQ
 into the CERCLA RQ methodology.  As   •
 proposed1, after the two-step CERCLA
 RQ process had been applied to the
 chemicals, an additional step  of
 comparing the tentative RQ to the
 substances' TPQs was applied. If the
 TPQ was lower than the tentative RQ,
 the RQ would be adjusted to t
  level or lower.

 VI. Regulatory Analyses

 a. Executive Order 12866       :
   Under Executive Order 12866, (58 FR
 51,735) of October 4, 1993. the Agency
 must determine whether the regulatory
 action is "significant" and therefore
 subject to review by the .Office of
 Management and Budget (OMB) and the
 requirements of the Executive Order.
 The Order defines "significant
 regulatory action" as one that is likely
 to result in a rule that may:
   (l) Have an annual"effect on the
 economy of $ 100 million or more or ,
 adversely affect in a material way the
 economy, a sector of the economy,
 productivity, competition, jobs, the
 environment, public health or safety, or
 State, local or tribal governments or
 communities;
  • (2) Create a serious inconsistency or
 otherwise interfere with an action taken
 or planned by another agency;
   (3) Materially alter the budgetary
 impact of entitlements, grants, user fees,
• or loan programs or the rights arid
 obligations of recipients thereof; or .
   (4) Raise novel legal or policy issues
 arising out of legal mandates, the
 President's priorities, or the principles
. set forth in the Executive Order.
  It has been determined that this rule
 is not a "significant regulatory action"
 under the terms of Executive Order
 12866 and is therefore not subject to   ,
 OMB review.                .
 b. Regulatory Flexibility Analysis ••
  Pursuant to the Regulatory Flexibility
 Act, 5 U.S.C. 601 erseg., whenever an
 agency is required to publish a notice of
 rulemaking for any proposed or final  •
 rule, it must prepare and make available
 for public comment a regulatory
 flexibility analysis that describes the
 effect of the rule on small entities (i.e.,
 small businesses, small organizations,
 and small governmental jurisdictions).
 This analysis is unnecessary, however,
 if the agency's administrator certifies
 that the rule will not have a significant
 economic effect on a substantial number
 of small entities.
  -EPA has examined this rule's
 potential effects on small entities as
 required by the Regulatory Flexibility
 Act. It has determined that today's final
 rule will not have a significant
 economic effect on a substantial number
 of small entities. The'overall economic
 effect of this regulation has been
 determined to  equate to 6,249 hours of
 burden reduction (with no added'
 burden) at a total cost saving of
 $355,628 per year to all regulated
 entities. Therefore, this regulation will
 have a cost savings, and not have a
 significant impact on small businesses.
 c. Paperwork Reduction Act
   The information collection
 requirements contained in this final rule
 have been approved by OMB under the
 provisions of the Paperwork Reduction
 Act, 44 U.S.C. 3501 etseq., and have
 been assigned OMB control number
 2050^0092 (EPA Information Collection
 Request No.  1395.2). Copies of the
 information collection requests may be
 obtained from Sandy Farmer, OPPE

 EnyironmentalProtection Agency
 (2136), 401 M Street, SW.. Washington,
 DC 20460  or by calling (202) 260-2740.
   As indicated in the Section I
 Introduction, the mandatory reporting
 requirements under-EPCRA section 304
 serve as a trigger for informing state and
 local governments of a.release, so that
 state and local personnel can evaluate
.the need for any necessary action in a
 timely fashion. EPCRA section 304 also
 requires the submittal of a written
 follow-up  notice to the same state and
 local entities.       •               :
   The public reporting burden for the
 collection  of information pursuant to
 EPCRA section 304 is estimated to take,
 on average, 5 hours per response. This
 estimate includes the time required to
 make the call and to develop the written
 follow-up  notice.            ..•_".
   Because.the RQs for almost all of the
 substances included in today's rule are
 to be raised, the net reporting and
 recordkeeping burden associated with
- reporting releases of these substances
 under EPCRA section 304 is expected to
 decrease. As demonstrated in an
 economic  impact analysis (EIA), the
 Agency estimates that the total burden .
 reduction  for notification to SERCs and
 LEPCs, and notification to 911 services
 in transportation-related incidents, and
 the completion of follow up reports will
 equate to 6,249 hours at a total cost

 d. Unfunded Mandates Reform Act  ,
   Title II of the Unfunded Mandates
 Reform Act of 1995 (UMRA), Public
 Law. 104-4, establishes requirements for
 Federal agencies to assess the effects of
 .their regulatory actions on State, local,
 and tribal governments and the private
 sector. Under section 202 of the UMRA,
 EPA generally must prepare a written
 statement, including a cost-benefit
 analysis, for proposed and final rules
 with "Federal mandates" that may
 result in expenditures to State,  local,
 and tribal governments, in the aggregate!
, or to the private sector, of $ 100 million
 or more in any one year. Before      :
 promulgating an EPA rule for which a
 written statement is needed, section 205
 of the UMRA generally requires EPA to
 identify and consider a reasonable
 number of regulatory alternatives and
 adopt the least costly, most cost-
 effective or least burdensome alternative
 that achieves the objectives of the rule.   .
 The provisions of section 205 do not
 apply when they are inconsistent with
 applicable law. Moreover, section 205 :
 allows EPA to adopt an alternative other
 than the least costly, most cost-effective
 or least burdensomefalternative if the
 Administrator publishes with the final
 rule an explanation why that alternative
 was not adopted. Before EPA establishes
 any regulatory requirements that may
 significantly or uniquely affect small
 governments, including tribal
 governments, it.must have developed
 under section 203 of the UMRA a small
 governmentagency plan. The plan must
 provide for notifying potentially
 affected small governments, enabling
 officials of affected small governments
 to have meaningful and timely  input in
 the development of EPA regulatory
 proposals with significant Federal
 intergovernmental mandates, and
 informing, educating, and advising
 small governments on compliance with
 the regulatory requirements.
   EPA has determined that this rule
 does not contain a Federal mandate that
 may result in expenditures of $100
 million or more for State, local, and
 tribal governments, in the aggregate, or
 the private sector  in any one year.
 Because the RQs for almost all of the
 substances included in today's rule are
 to be raised, the net reporting and
 recordkeeping burden associated with
 reporting releases of these substances
 under EPCRA sf.cXion 304 is expected to
 •decrease. As demonstrated in an
 economic impact analysis (EIA), the
 Agency estimates that the total burden
 reduction for notification to SERCs and
 LEPCs, and notification to 911  services'
 in transportation-related incidents, and
 the completion of follow up reports will
 equate to 6,249 hours at a total cost
 savings of $355,628 per year.'Thus,
 . today's rule is not subject to the
 requirements of sections 202 and 205 of
 the UMRA.  '
    EPA has determined that this rule
 contains no regulatory requirements that
 might significantly or uniquely affect

             Federal Register /. Vol. 61. No.  89 / Tuesday, May  7,  1996 / Rules and  Regulations
                                                                     20477
have reduced reporting requirements
under EPCRA section 304.
c. Hydrogen Chloride
  Several commenters correctly pointed
out that the phrase "gas only" was
omitted from the hydrogen chloride
listing in the tables proposing to revise
Appendices A and B to 40 CFR part 355.
In today's rule, this omission is
corrected.
  In the final rule published in the
Federal Register December 27, 1989 (54
FR 53057). EPA raised the reportable
quantity for Hydrogen chloride (gas
only) to 5,000 pounds. This is the same
as the reportable quantity for hydrogen
chloride (a synonym of hydrochloric
acid) under CERCLA section 103.

d. Sulfur Trioxide
  Several commenters believed that a
reportable quantity for sulfur trioxide
above 100 pounds is warranted. EPA,
however, disagrees. The 100 pound TPQ
for sulfur Trioxide is based upon acute
toxicity. EPA agrees that some releases
of sulfur trioxide above 100-pounds may
not be hazardous based upon the
conditions of the release (e.g. from a
flare or stack). However, 100-pound
releases of sulfur trioxide at ground
level (e.g. releases during sulfuric acid
and explosive manufacturing) may pose
a hazard to the community.  An RQ
incorporates all probable release
scenarios so that persons off-site can
determine the level of response
necessary. Therefore, the Agency
believes that the 100-pound RQ for
sulfur trioxide based upon its acute
toxicity is appropriate.
IV.  Listing Corrections
  EPA is making final a rule that was
originally proposed on October 30,
1994, to remove phosphorus pentoxide,
diethylcarbamizine citrate, finitrothion
and tellurium from the extremely
hazardous substances list.3
  Substances are listed as EHSs based
on toxicity criteria. Substances are
screened using acute animal toxicity
data for the most sensitive mammalian
species and are placed on the list if they
meet one of the following criteria:
• LCso4 £0.5 mg/L
• Dermal LDsos£ 50 mg/kg
• Oral LDjo S 25 mg/kg
  1 On October 30.1994. EPA proposed the
adjustment of the TPQ for isophorone diisocyanate.
The final rule on this adjustment will be published
in a future notice.
  4 "LCso" refers to that concentration of a
substance in the air that is expected to cause the .
death of 50 percent of a defined experimental
population.
  J "LDjo" refers to that dose of a substance
expected to cause the death of SO percent of a
defined experimental population.
   If LCso or LD50 data are not available,
 then LCi_o or LDi_o data are used.
 Substances that meet one of these
 criteria have the potential for causing
 harm if accidently released and are,
' therefore, designated as EHSs.
   EPA listed phosphorus pentoxide
 based on information presented in an
 abstract. This source reported an LC5o of
 0.061 mg/L for guinea pigs and an LCso
 of 0.271 mg/L for mice exposed for 1
 hour to smoke generated from burning
 red phosphorus. A significant limitation
 of this study is that the toxic effects
 cannot be directly related to phosphorus
 pentoxide. Therefore, these data are
 insufficient for listing phosphorus
 pentoxide as an EHS. In addition, the
 Elemental Phosphorus Ad Hoc Solid
 Waste Group submitted a study that
 indicated that the LCso for rats exposed
 to phosphorus pentoxide for 4  hours is
 greater than 0.99 mg/L, well above the
 .5 mg/L listing criteria. Based on the
 insufficient information in the original
 study and the information of the more
 recent study, EPA has decided to
 remove phosphorus pentoxide from the
 EHS list.
   EPA listed diethylcarbamazine citrate
 based on information presented in a
 Russian data compilation that listed an
 LCso for rats equal to 0.309 mg/L for a
 4-hour exposure. Review of this
 information indicated that the toxicity
 values presented were unverifiable
 because the study details were not
 available. In addition, SmithKline
 Beecham submitted a study that
 reported no deaths of rats from exposure
 to either 1.63 mg/L or 2.38 mg/L for 1
 hour. Based on the poor quality of the   ;
 original study and the additional
 information received, EPA has decided
 to remove diethylcarbamazine citrate
 from the EHS list.
   EPA listed fenitrothion based on a
 study that reported an LCso equal to
 0.378 mg/L for a 4-hour exposure. EPA's
 review of this study concluded that a
 toxic impurity had resulted in an
 erroneously low value for the LCso. In
 addition, a surfactant was present that
 altered the  permeability of the skin and
 cell membranes of the test animals,
 making them more, susceptible to
 fenitrothion's toxic effect. Information
 submitted by Sumitomo Chemical
 America, Inc., reported an LCso greater
 than 2.210 mg/L. Based on the Agency's
 review and'tlA additional information,
 . fenitrothion is being deleted from the
 EHS list.
   EPA listed tellurium metal based on
 a study that reported an oralLDso of 20
 mg/kg. Review of this study indicted
 that sodium tellurate, which is listed as
 an EHS, was used in the study rather
 than tellurium metal. The Selenium
 Tellurium Development Association
 also submitted a study that reported an
 LDso greater than 5000 mg/kg-for
 tellurium metal. Based on this
 information, EPA is deleting tellurium
 from the list of EHSs:

 V. Response to Comments on October
 12, 1994, Proposal

  EPA received one comment from the
 Clean Water Fund of North Carolina
 objecting to the removal of phosphorus
 pentoxide from the EHS list. The Clean
 Water Fund questions the validity of an
 unpublished 1987 toxicity study
 showing no toxic effects in exposed
 animals, at levels up to .99 mg/L of
 phosphorus pentoxide aerosol. That
..study however; did not determine the
 level of the chemical in question in the
 chamber atmosphere. The analytical
 method determined only total
 phosphorus, which was then converted
 to an equivalent concentration of
 phosphorus pentoxide in air. The Clean
 Water Fund argues, therefore, that the
 pentoxide should remain on the list     '
 because the 1980 and 1982 combustion
 experiments established that the
'pentoxide was a major component of the
 smoke and "because the analytical
 techniques employed by the 1980 study
 may have actually synthesized the
 pentoxide from other (possibly less     '•
 dangerous) phosphorus compounds
 actually present in the test chamber."
 The Agency assumes Clean Water Fund
 believes that because the pentoxide
 could have been synthesized from less
 toxic compounds, the pentoxide
 presented the toxic character of the test
 chamber gas.
  EPA disagrees. The 1980 and 1982
 studies show that, in burning the
 phosphorus, there is a potential for the
 production of several oxides of
 phosphorus. Regardless of how
 pentoxide was formed (as noted by the
 Clean Water Fund) or whether the
 various oxide cprcpounds are more or
 less toxic,' the fact still remains that the ,
 studies did not distinguish which of the
 various oxides caused the high toxicity
 of the smoke. While the 1987 study
 showed no toxicity of phosphorus
 pentoxide, it also is  not conclusive
 because it did not indicate a direct
 measurement of phosphorus pentoxide
 in the chamber and the pentoxide could
 have hydrolyzed to possibly less toxic
 constituents. ,On balance, none of the
 studies presented show that phosphorus
 pentoxide meets the toxicity criteria.
 Accordingly, EPA is removing the
 chemical from the EHS list.

almost all of the substances included in
today's rule are to be raised, the net
reporting and recordkeeping burden
associated with reporting releases of
these substances under EPCRA section
304 is expected to decrease. Small
governments will no longer receive
notifications and written follow-up
reports from facilities that have releases
of extremely hazardous substances less
that the substances' TPQ.
