which EPA promulgated pursuant to _
Section 105 of the Comprehensive
Environmental Response,
Compensation, and Liability Act of 1980
(CERCLA), as amended. EPA and the
State of Minnesota have determined that
all appropriate Fund-financed responses
under CERCLA have been implemented
and that no further response by
responsible parties under CERCLA is
appropriate.
EFFECTIVE DATE: May 7, 1996.

Bethel Demolition Landfill Site in
Anoka County, Minnesota. A Notice of
Intent to Delete was published March
13, 1996, (61 FR 10298) for this site. The
closing date for comments on the Notice
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
of the Emergency Planning and
Community Right-to-Know Act of 1986
-------

Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations
(EPCRA), Title III of the Superfund
Amendments and Reauthorization Act
of 1986. EPA is raising the statutory
rcportablc 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.

I. Introduction
a. Statutory Authority
This regulation is issued under
sections 302, 304 and 328 of the
Emergency Planning and Community
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."
-------
Federal Register I 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 ari 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 diisocyanate. 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 oh the
developing a rulemaklng to adjust the CERCLA and
EPCRA one-pound RQs for these 11 substances. The
substances are identified in 40 CFR Part 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 substance, 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
proposed to modify the CERCLA RQ
methodology by integrating the TPQ
into the CERCLA RQ methodology. As
proposed, 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 the TPQ
level or lower.
-------
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
and 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
3 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. and 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 the
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 regulatory requirements.
EPA believes that the TPQ
methodology is appropriate for these
chemicals. Although the RQs and TPQs
trigger two distinct notification
requirements, both 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-pounds 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 aire continuous
-------
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
toxiciry is appropriate. •
IV. Listing Corrections
EPA is making final a rule that was
originally proposed on October 30,
1994, to remove phosphorus pentdxide,
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:
• LCjn•>Ł 6.5 mg/L »
• Dermal LDso 5S 50 ing/kg
• Oral LDsn Ł 25 mg/kg
3 On October 30, 1994, EPA proposed the
adjustment of the TPQ for isophorone dilsocyanate.
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.
5 "LDso" refers to that dose of a substance
expected to cause the death of 50 percent of a
defined experimental population.
If LCso or LDso data are not available,
then LCLo or LDix> 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 LCso 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 rrig/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 fenitrothiori 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 the additional information,
fenitrothion is being deleted from the
EHS list.
EPA listed tellurium metal based on
a study that reported an oral LDso 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 toxiciry 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 compounds are more or
. less toxic, the fact still remains that the
studies did not distinguish which of the
various oxides caused the high toxiciry
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 toxiciry criteria.
Accordingly, EPA is removing the '
chemical from the EHS list.

Federal Register / Vol. 61, No. 89 / Tuesday, May 7, 1996 / Rules and Regulations
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:
(1) 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 and
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 etseq.. whenever an
agency is required to publish a notice of
rulcmaklng 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 et seq., 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
Regulatory Information Division, U.S.
Environmental Protection 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 (ElA), 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.
Send comments on the ICR to the
Director, OPPE Regulatory Information
Division, U.S. Environmental Protection
Agency (2136), 401 M Street, SW.,
Washington. DC 20460; and to the
Office of Information and Regulatory.
Affairs, Office of Management and
Budget, 725 17th Street. NW.,
Washington, DC 20503, marked
"Attention: Desk Officer for EPA."
Include ICR number 1395.2 in any
correspondence.
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 burdensome alternative 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
government agency 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 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
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 I Vol. 61, No. 897 Tuesday, May 7, 1996 / Rules and Regulations 20479
small governments. 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. 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.
