Emergency Planning and Community

Right to Know Programs

AGENCY: U.S. Environmental Protection

Agency (EPA).

ACTION: Interim final rule.

SUMMARY: Section 302 of the Superfund

Amendments and Reauthorization Act

of 1986 (SARA), signed into law on

October 17, 1986, requires the

Administrator of EPA to publish a list of

extremely hazardous substances within

30 days. The Administrator is also

required to simultaneously publish an

interim final regulation establishing a

threshold planning quantity for each

substance on the list and initiate a

rulemaking to finalize these regulations.

The list and planning quantities trigger

emergency planning in States and local

communities under SARA. The purpose

of this rule is to publish the statutorily

prescribed list of extremely hazardous

substances and the corresponding

threshold planning quantities for those

substances. This rule also codifies the

reporting and notification requirements

under SARA for facilities at which

extremely hazardous substances are

present. Finally, a companion proposed

rule, published elsewhere in today's

Federal Register, initiates a rulemaking

to revise the list of substances, the

threshold planning quantities and

reporting regulations.

EFFECTIVE DATES: This rule becomes

effective on: November 17, 1986. Other

dates relevant to this rule include the

following:

1. The emergency release notification

requirements become effective on

November 17, 1986.

2. State emergency response

commissions should be established by

April 17, 1987.

3. Facility notifications for emergency

planning are required by May 17, 1987.

4. State commissions should establish

emergency planning districts by July 17,

1987.

5. State Commissions should establish

local emergency planning committees by

August 17, 1987.

6. Facility notifications to local

committees concerning facility

representatives are due by September

17, 1987.

COMMENTS: Written comments should be

submitted on or before January 2, 1987.

I. Introduction

A. Statutory Authority

These regulations are issued under

Title III of the Superfund Amendments

and Reauthorization Act of 1986, (Pub. L.

99-499), ("SARA" of "the Act"). Title III

of SARA is known as the Emergency

Planning and Community Right-to-know

Act of 1986.

B. Background

1. Superfund Amendments and

Reauthorization Act of 1986 (SARA)

On October 17, 1986, the President

signed into law the Superfund

Amendments and Reauthorization Act

of 1986 ("SARA") which revises and

extends the authorities established

under the Comprehensive

Environmental Response, Compensation

and Liability Act of 1980 ("CERCLA")..

Commonly known as "Superfund,"

CERCLA provides authority for federal

cleanup of abandoned toxic waste sites

and response to releases of hazardous

substances. Title III of SARA

establishes new authorities for

emergency planning and preparedness,

community right to know reporting, and

toxic chemical release reporting.

2. Title III

Title III of SARA, also known as the

"Emergency Planning and Community

Right-to-Know Act of 1986", is intended

to encourage and support emergency

planning efforts at the State and local

level and provide residents and local

governments with information

concerning potential chemical hazards

present in their communities.

The emergency planning requirements

of this Act recognize the need to

establish and maintain contingency

plans for responding to chemical

accidents which can inflict health and

environmental damage as well as cause

significant disruption within a

community.

Title III is organized into three

subtitles. Subtitle A, which establishes

the framework for local emergency

planning, will be described in more

detail in the following section. Subtitle B

provides the mechanism for community

awareness with respect to hazardous

chemicals present in the locality. This

information is critical for effective local

contingency planning. Subtitle B

includes requirements for the

submission of material safety data

sheets and emergency and hazardous
Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations 41571

chemical inventory forms to State and

local governments, and the submission

of toxic chemical release forms to the

States and the Agency. Subtitle C

contains general provisions concerning

trade secret protection, enforcement,

citizen suits, and public availability of

information.

3. Subtitle A

Subtitle A of Title III is concerned

primarily with emergency planning

programs at the State and local levels.

Section 301 requires each State to

establish an emergency response

commission by April 17, 1987. The State

emergency response commission will

have several tasks critical to the

implementation of local contingency

planning and response efforts. It will be

responsible for establishing emergency

planning districts and appointing local

emergency planning committees. The

Commission will also be responsible for

the supervision and coordination of the

activities of the local emergency

planning committees.

Section 302 requires the Administrator

of EPA to publish a list of extremely

hazardous substances and threshold

planning quantities for such substances.

Any facility where an extremely

hazardous substance is present in an

amount in excess of the threshold

planning quantity is required to notify

the State commission by May 17, 1986.

Other facilities may also be designated

by the Commission or the Governor.

Section 303 governs the development

of comprehensive emergency response

plans by the local emergency planning

committees and provision of facility information to the committee. Section

304 establishes requirements for

immediate reporting of certain releases

of hazardous substances to the local

planning committees and the State

emergency response commission, similar

to the release reporting provisions under

section 103 of CERCLA. Section 304 also

requires follow up reports on the

release, its effects, and response actions

taken.

Finally, section 305 addresses

emergency preparedness and training,

with special emphasis on hazardous

chemicals. The Administrator is also

required under section 305 to conduct a

review of emergency systems.

4. Section 302

Section 302 defines the specific list of

extremely hazardous substances and

requires EPA to publish the list within 30

days after the enactment of SARA. The

list of extremely hazardous substances

is defined in section 302 as "the list of

substances published in November, 1985

by the Administrator in Appendix A of

the Chemical Emergency Preparedness

Program Interim Guidance". This list

was established by EPA to identify

chemical substances which could cause

serious irreversible health effects from

accidential releases.

Section 302 further requires EPA to

establish threshold planning quantities

for each of the 402 extremely hazardous

substances through an interim final

regulation. At the same time, EPA must

initiate a rulemaking effort to finalize

these threshold planning quantities. This

threshold planning quantity is the total

amount of any listed extremely

hazardous substance present at any one

time at a facility, regardless of location,

number of containers, or storage

method, which will trigger the planning

notification. Section 302 gives the

Administrator broad flexibility in

establishing these quantities. If EPA

does not publish interim final rules

establishing the threshold planning

quantities by thirty days after enactment

of SARA, then the threshold planning

quantity becomes two pounds for each

extremely hazardous substance.

Under section 302(a)(4) the

Administrator may make revisions to

the list and threshold planning

quantities. Any revisions must take into

account the toxicity, reactivity,

volatility, dispersibility, combustibility,

or flammability of a substance.

Toxicity must include any short- or

long-term effect resulting from a shortterm exposure to the substance in

question. Thus, extremely hazardous

substances are characterized as those

which can cause serious health effects

with only a single exposure.

A facility is subject to the emergency

planning requirements of section 302 if

any extremely hazardous substance is

present at the facility in a quantity

greater than the threshold planning

quantity established for that substance.

The Governor or the State emergency

response commission may designate

additional facilities to be covered if such

designation is made after public notice

and opporunity for comment.

Within seven months after enactment

of SARA, May 17, 1987, the owner/

operator of each facility subject to the

provisions of section 302 must notify the

State emergency response commission

of the state in which it is located that it

is subject to that Section. After May 17,

1987 an owner/operator must notify the

State emergency response commission

within sixty days after the facility

begins handling an extremely hazardous

substance. Failure to comply with these

reporting provisions may, under section

325, result in injunctive relief or the

imposition of a civil penalty in an

amount of up to $25,000 for each day in

which the violation continues.

Lastly, the State emergency response

commission must provide the

Administrator of EPA with information

concerning the notifications received

from any facility under section 302.

Today's rule publishes the list of

extremely hazardous substances and

corresponding threshold planning

quantities, as required by section 302.

This rule also codifies related statutory

reporting requirements applicable to

facilities at which extremely hazardous

substances are present. Finally, today's

rule represents an initiation of an

Agency rulemaking to revise this rule as

appropriate in response to public

comment. A companion proposed rule,

published elsewhere in today's Federal

Register, specifically sets out for public

comment all aspects of this final rule

and proposes revisions to the list

published today.

II. Analysis of the Interim Final Rule

A. Emergency Planning Program

The emergency planning program is a

first step toward chemical emergency

planning for extremely hazardous

substances. After the enactment of

Superfund, it became apparent that

emergency response to accidental

releases of hazardous substances,

although vital to the protection of public

health and the environment, was not

enough protection against the possibility

of the release of extremely hazardous

substances. For many chemicals the

magnitude of the endangerment to

surrounding populations upon release is

such that it is not sufficient merely to

plan for cleanup of spills once they have

occurred. Rather, it is important to

facilitate emergency planning which can

help prevent the accident and to prepare

facilities and the surrounding or

adjacent community for the contingency

of a release and the resulting emergency

response.

Particularly after the Bhopal, India

disaster of December, 1984, it became

clear that substances which are highly

acutely toxic and have a high potential

for becoming airborne posed a special

problem for emergency response. In

many cases, by the time any emergency

response personnel can arrive on the

scene of a release, the cloud has already

done its damage to public health or the

environment and dissipated. For such

extremely hazardous substances, early

comprehensive emergency planning for

the possibility of a release is vital to

effective public and environmental

protection.
41572 Federal Register'/ Vol. 51, No. 221 / Monday, November 17, 1986 /'Rules and Regulations

1. Purpose of the List and Threshold

Planning Quantities

The extremely hazardous substances

list of 402 substances was developed as

part of the Chemical Emergency

Preparedness Program (CEPP) and is the

result of over a year of EPA effort. EPA

initiated the CEPP as part of its ongoing

preparedness responsibilities for

hazardous substance releases under

CERCLA and for addressing toxic

substances under the Toxic Substances

Control Act (TSCA). The program was

announced in June, 1985, as part of the

Agency's Air Toxics Strategy for

addressing both continuing and

accidental releases of toxic substances

into the air. CEPP is designed to

increase public awareness of chemical

hazards in communities and to assist

States and communities in developing

preparedness programs and response

capabilities for releases of hazardous

chemicals into the environment.

The Agency first developed the

extremely hazardous substances list as part of the CEPP along with guidance

materials to aid localities in focusing on these chemicals to address the

development of community emergency

response plans. The list and guidance

materials (issued November, 1985) were

designed to enable a community to

obtain information on the location of

potential chemical hazards in the

community. This information could be

used to help the community take

preventive actions and plan responses

to accidental releases of these extremely

hazardous substances. A notice of

availability of the CEPP Interim

Guidance was published in the Federal

Register on December 17, 1985.

Title III of SARA mandates the type of

program advocated by the Agency's

CEPP. It requires State and local

governments to establish the

infrastructure needed to facilitate

emergency planning and provides

technical support to these programs. It

also requires certain facilities to supply

the information on chemicals present at

the facility which is necessary for

contingency planning.

The extremely hazardous substances

list and its threshold planning quantities are intended to help the local

community focus on the chemicals and

facilities of the most immediate concern from a community emergency planning

and response perspective. EPA strongly

emphasizes, however, that while the list

published today includes many of the

chemicals which may pose an immediate hazard to a community upon

release, it is not to be considered a list

of all chemicals which are hazardous

enough to require community emergency

response planning. There are tens of

thousands of compounds and mixtures

in commerce in the United States, and in

specific circumstances, many of them

could be considered toxic or otherwise

dangerous. The list published today

represents only a first step towards

development of an effective emergency

response planning effort at tle

community level. Without a preliminary

list of this kind, it would be very difficult

for most communities to know where to

begin identification of potential

chemical hazards among the many

chemicals present in any locality.

Similarly, the threshold planning

quantities are not absolute levels above

which the extremely hazardous

substances are dangerous and below

which they pose no threat at all. Rather,

the threshold planning quantities are

intended to provide a "first cut" for

community emergency response

planners where these extremely

hazardous substances are present. After

identification of facilities at which

extremely hazardous substances are

present in quantities greater than the

threshold planning quantities, the local

community will have the basis for

further analysis of the potential danger

posed by these facilities. Also, they will

be able to identify other facilities posing

potential chemical risks to the locality,

and develop contingency plans to

protect its citizens from releases of

hazardous chemicals. Sections 311 and

312 of Title III provide a mechanism

through which a community will receive

Material Safety Data Sheets and other

information on extremely hazardous

substances, as well as many other

chemicals, from facilities which handle

them. A community can then assess and

initiate planning activities, if desirable,

for quantities below the threshold

planning quantity.

In addition to the assistance provided

by the extremely hazardous substance

list and the threshold planning

quantities, community emergency

response planners will be further aided

by the National Response Team's

proposed Hazardous Materials

Emergency Planning Guide which is

required under section 303(f) of Title Il1.

This document will be available for

public review and comment in

December. A separate notice of

availability will be published in the

Federal Register at that time. The

guidance document will be

supplemented in 1987 with a technical

publication developed by EPA to assist

local emergency planning committees in

the technical evaluation of potential

chemical hazards and the prioritization

of sites.

2. Responsibilities of Facilities Under

Subtitle A

Subtitle A established several

notification responsibilities for facilities

at which hazardous substances are

present or from which hazardous

substances are released. First, under

section 302, each facility where any

extremely hazardous substance is

present at any one time in a quantity

equal to or above the threshold planning

quantity established for that substance,

must notify the State emergency

response commission for the State in

which it is located.

This notification must be'provided

within seven months after the enactment

of SARA (May 17, 1987] or within 60

days from the time that the facility first

becomes subject to the notification

requirements in section 302, whichever

is later.

Second, under section 303(d), these

facilities must also designate a facility

representative who will participate in

the local emergency planning effort as a

facility emergency response coordinator.

This designation must be made by

September 17, 1987 or 30 days after

establishment of the local emergency

response committee, whichever is

earlier. Section 303(d) also requires

facilities to provide the committee with

information relevant to development or

implementation of the local emergency

response plan.

Section 304 requires notification by a

facility at which a hazardous chemical

is produced, used, or stored to the local

planning committee and the State

emergency response commission upon

release of a reportable quantity (RQ) of

any extremely hazardous substance or

other hazardous substance identified

under CERCLA section 101(14). This

notification is required even if a

threshold planning quantity of a

substance is not present at the facility.

Those extremely hazardous substances

for which an RQ has not been

established under CERCLA are given an

RQ of one pound under section 304 of

SARA. These RQ's will be adjusted in

later regulation by EPA. Section 304

requires both an immediate release

notification to the local committee and

State commission and a follow-up report

providing additional information on the

release, its impacts, and any actions

taken in response.

Under section 325, failure to comply

with these responsibilities may result in

the imposition of civil or criminal

penalties. States, local governments, and

citizens may also bring suit to enforce

many sections of the Act.
No. 221 / Monday, November 17, 1986 / Rules and Regulations 41573

3. Applicability

The emergency planning requirements

under section 302 are applicable to all

facilities which store, manufacture,

process, use, or otherwise handle at any

time an extremely hazardous substance

in an amount above the threshold

planning quantity established for that

substance in today's rule. Additionally,

after public notice and the opportunity

for comment, the Governor may

designate other facilities that will be

subject to these regulations. "Facility",

for the purposes of Title III, is defined as "all buildings, equipment, structures,

and other stationary items which are located on a single site or on contiguous

or adjacent sites and which are owned or operated by the same person (or by

any person which controls, is controlled

by, or under common control with, such

person)."

For purposes of emergency release

notification, under section 304 "facility"

is defined in section 329 to also include

transportation vessels or facilities.

However, section 304 notification

requirements apply only to facilities at

which hazardous chemicals are

produced, used, or stored and at which

there is a release of an extremely

hazardous substance or a CERCLA

hazardous substance.

4. Responsibilities of the States and

Local Communities Under Title III.

Title III also prescribes several

requirements with respect to emergency

planning for States and localities. First,

under section 301(a) the Governor of

each State is to appoint, within six

months of the enactment of SARA, April

17, 1987, a State emergency response

commission or designate a state agency

to have this responsibility. Until the

Governor appoints such a commission or state agency, responsibilities of the

Commission under Title III remain with

the Governor.

Section 301(b) further provides that

the State emergency response

commission will be responsible for the

establishment of emergency planning

districts in which local emergency : planning committees will be formed.

One month after the emergency planning

districts are established, the State

commission is responsible for

appointing the local emergency planning

committees.

Under section 301(c) local emergency

planning committees will have the initial

responsibility for establishing the

community emergency response plans

specified in section 303; and the ongoing

responsibility for updating, revising, and

exercising these plans.

B. List of Extremely Hazardous

Substances and Threshold Planning

Quantities

1. List of Extremely Hazardous

Substances

a. Statutory Requirement: As stated

above, the list of extremely hazardous

substances is defined in section 302 to

be the "same as the list of substances

published in November 1985 by the

Administrator in Appendix A of the

Chemical Emergency Preparedness

Program (CEPP) Interim Guidance."

Section 302 requires the EPA to publish

the list within 30 days of the enactment

of SARA.

One of the goals of the CEPP was to

increase community awareness of

chemical hazards, specifically acutely

toxic chemicals. To satisfy this goal, the

Agency developed the toxicity criteria to

assist communities in identifying acutely

toxic chemicals present in their midst.

Through identification of these

chemicals, communities could establish

priorities for developing comprehensive

emergency response plans. To further

assist the communities, the Agency

applied toxicity criteria to develop a

representative, but not exhaustive, list

of acutely toxic chemicals. It is this

representative list of 402 chemicals that

is presently designated in section 302 as

the list of extremely hazardous

substances.

The following sections discuss the

criteria for identifying extremely

hazardous substances.

b. Criteria for the List-i. Basis for the

Criteria. Considering the large number

of chemicals in commerce and the

variable nature of their individual.

inherent acute toxicities, the Agency

assumed for the purposes of the CEPP,

that it would be impractical for

communities to evaluate all of them. The

CEPP list was also based on the

assumption that communities would

want to focus emergency planning

efforts on the most acutely toxic

chemicals rather than on nontoxic

chemicals or those exhibiting lesser

acute toxicity. In an attempt to direct

community planning efforts to these

chemicals which, because of their

inherent acute toxicity, are most likely

to induce serious acute reactions

following short term exposure, the

Agency has specified selection criteria

that can be applied to toxicity data to

identify acutely toxic chemicals

(referred to as "extremely hazardous

substances" under Title III).

In defining the criteria, the Agency

had to identify the health effects of

concern and the data to be used.

Because there are very few human acute

toxicity data, the Agency elected to use

acute toxicity data derived from

experiments with animals to infer

potential for acute toxic effects in

humans. The Agency assumed that

humans and animals (mammals), on the

average, are similar in intrinsic

susceptibility to toxic chemicals and

that animal data can be used as a

surrogate for human data. This

assumption forms one basic premise of

modern toxicology and is a key

component in the regulation of toxic

chemicals.

The Agency chose to utilize data on

lethality because it represents the most

immediate concern in an emergency

situation. Additionally, such data can be

used as a comparison among many

substances whose mechanisms and sites

of action may be markedly different.

Moreover, acute lethality data for many

chemicals are the most commonly

reported toxicity information and are

available in accessible databases.

Lethality data from animal toxicity tests

are generally expressed as the median

lethal concentration (LCa) when the

substance has been administered by

inhalation or the median lethal dose

(LDso) when the substance has been

administered orally or dermally. These

data represent dose levels or

concentrations of a chemical that

resulted in the death of 50 percent of the

test animals exposed at the indicated

dose level.

ii. Criteria. The Agency adopted the

specific criteria shown in Table 1 to

identify extremely hazardous

substances that may present severe

health hazards to humans following

short term exposure to chemicals during

a chemical accident or other emergency.

The selection criteria are only screening

tools to identify highly acutely toxic

chemicals. Under these criteria, a

chemical is to be considered a potential

acute human toxicant if animal test data

in any mammalian species are identified

with a value less than or equal to that

stated for the LC6 or LD5o criteria for

any one of three exposure routes.*

Extremely hazardous substances are

those defined with inhalation LC50

values of less'than or equal to 0.5

milligrams per liter of air, dermal LD5o

values of less than or equal to 50

milligrams per kilogram of body weight,

or oral LD5o values of less than or equal

to 25 milligrams per kilogram of body

weight. The specific values chosen are

recognized by the scientific community

as indicating a high potential for actute

toxicity, and chemicals meeting the

toxicity criteria are considered potential .hazards.

Federal Register / Vol. 51,
41574 Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations

TABLE 1.-CRITERIA To IDENTIFY ACUTELY Toxic CHEMICALS THAT MAY PRESENT SEVERE

HEALTH HAZARDS TO HUMANS EXPOSED DURING A CHEMICAL ACCIDENT OR OTHER EMERGENCY

Route of Exposure Acute Tosicity Measure Value

Inhalation . Median Lethal Concentration in Air (LC.) .......... Less than or equal to 0.5 milligrams per liter of air. Dermal ............ Median Lethal Dose ILDo) ................................................... Less than or equal to 50 milligrams per kilogram of

body weight

Oral ................. Median Lethal Dose (LD,) ............. . . Less than or equal to 25 milligrams per kilogram of

body weight.

The route by which the test animals absorbed the chemical, i.e., by breathing it in air (inhalation), by absorbing it through the skin (dermal). or by ingestion (oral). = LC.: The concentration of the chemical in air at which 50 percent of the test animals died. LD: The dose which killed 50

percent of the test animals. In the absence of LCm or LD. data, LCo or LDo data should be used. LC : Lethal Concentration Low, the lowest concentration in air at which any test animals died. LDuo: Lethal Dose Low, the lowest dose at which any test animals died.

The primary route of exposure with

which the Agency is concerned is

inhalation. In using data on oral and

dermal acute lethality to infer concern about inhalation toxicity, the Agency was not as much concerned with these

specific routes of exposure in humans as with identifying compounds with

inherent high potential for acute

toxicity.

Even with the amount of animal data

that are available, there exist chemicals

for which there are no standard acute

toxicity test data. In those cases where

toxicity testing has not determined an

LDo or LCso, the Agency selected an alternative measure of acute toxicity:

The lowest dose or concentration at

which some animals died following

exposure (LDLo or LCLo). These values

may be more variable than those

provided from median lethality tests, but

for the purposes of screening large

numbers of chemicals, it was deemed

necessary to provide a second level

screening tool in preference to missing

potentially toxic chemicals because they were not adequately tested.

The Agency chose to use data from

the most sensitive mammalian species

instead of data from only one specific

species because at present it is not

possible to predict which species is the

appropriate surrogate for humans for a

given chemical.

Acute inhalation toxicity testing

depends upon the concentration of the

chemical in air and the duration of the

exposure periods. Because of this, LC5o

and LCL values for a chemical may

vary depending upon how long the

animals were exposed to the substance.

The Agency chose also to make

maximum use of available acute toxicity

data to screen for acutely toxic

chemicals and, therefore, chose to use LC5 o and LCo values with exposure

periods up to 8 hours or with no reported exposure period. The Agency

recognizes that this may be a

conservative approach.

The screening criteria selected by the

Agency are basically consistent with

internationally accepted criteria used by

both the European Economic

Community and the World Bank.

However, the Agency has adopted a

more conservative approach by

modifying the selection criteria in three

ways:

1. Lethality data are not limited to

data on rats, but include data on the

most sensitive mammalian species

tested;

2. LCso data with inhalation exposure

periods up to 8 hours are included as

compared to using only data from 4 hour

exposure tests; and

3. LDto and LCL data are used when

LDso or LC5o data are unavailable.

iii. Application of the Criteria. The

screening criteria can be applied to any

experimental data or data base on

chemical substances that includes acute

animal toxicity data. The Agency

applied the criteria to a specific toxicity

data base, the Registry of Toxic Effects

of Chemical Substances (RTECS),

maintained by the National Institute of

Occupational Safety and Health

(NIOSH). The RTECS data base was

used as the principal source of toxicity

data for identifying acutely toxic

chemicals because it represents the

most comprehensive repository of acute

toxicity information available with basic

toxicity information and other data on

more than 79,000 chemicals. It is widely

accepted and used as a toxicity data source by industry and regulatory

agencies alike. Although RTECS is not

formally peer-reviewed, the data

presented are from scientific literature

which has been edited by the scientific

community before publication. The

Agency recognizes the limitation

associated with the lack of peer-review,

but for the purposes of screening acute

toxicity data, RTECS represents the

single best source of information.

In addition, the Agency selected only

those chemicals considered to be in

current production by reviewing the

non-confidential 1977 Toxic Substances

Control Act (TSCA) Inventory and the

current EPA list of active pesticide

ingredients. The TSCA Inventory is a

listing of chemicals in production at the

time the Inventory was compiled.

Chemicals entering commerce since 1977

through the Premanufacturing Notice

(PMN) review process under Section 5 of

TSCA also were screened for acute

toxicity data and compared to the

criteria for possible inclusion on the list.

Radioactive materials and chemical

substances in research and development

stages, as well as those manufactured,

processed, or distributed in commerce

for use as food additives, drugs, or

cosmetics are not listed in the TSCA

inventory and hence, were not

considered. If research chemicals that

meet the criteria are produced for

commercial use under TSCA or for

pesticide use under the Federal

Insecticide, Fungicide, and Rodenticide

Act (FIFRA), EPA will identify such

chemicals through its PMN review"

program or pesticide registration

program and list them under section 302

in future rulemakings. The Agency

solicits comments concerning the

addition of chemicals in food, drugs,

cosmetics and radioactive materials to

the list of extremely hazardous

substances.

iv. Other Toxic Chemicals. Chemicals

with acute lethality values not meeting

the criteria values discussed in the

previous section are not necessarily

safe. In fact, many may be toxic to

humans and may represent hazards to

the community in accidental release

situations. The Agency identified some

of these potentially toxic chemicals

using criteria based on factors such as

high production volume, acute lethality,

and known risk, as indicated by the fact

that these chemicals have caused death

and injury in accidents.

c. List of 402 Chemicals: Application

of the criteria discussed above to the

RTECS data base and subsequent

review of the TSCA Inventory and the

FIFRA active pesticide ingredient list

led to the identification of 378

chemicals. In addition, one chemical

meeting the toxicity criteria was

identified from the Premanufacture

Notices. Twenty-three additional

chemicals were identified as potentially

hazardous, using the criteria described

above for "other toxic chemicals". These

chemicals were added to the list on the

basis of toxicity, high production

volume, and known risk. The list of 402

extremely hazardous substances is set

forth in Appendices D and E.

The Agency recognizes that the

criteria used to establish the extremely

hazardous substance list address only

lethality, and do not account for all

effects that may be associated with

acute exposure to chemicals. Criteria

are being considered for other health
No. 221 / Monday, November 17, 1986 / Rules and Regulations 41575

effects after acute exposures to toxic

chemicals. In addition, section 302

requires the Agency to also consider

long-term health effects resulting from

short-term exposures to these chemicals.

The Agency does not presently have

sufficient data on such effects and

requests data from commenters on

chronic effects from short-term

exposures and comments on how these

effects should be incorporated into

criteria for revisions to the list. The

Agency also requests any other

comments on the appropriate criteria for

additions to or deletions from the list.

A companion proposed rule, published

elsewhere in today's Federal Register,

specifically proposes the addition and

deletion of certain substances from

Appendices D and E.

2. Threshold Planning Quantities

A. Statutory Requirement: Under

section 302 the Agency is required to

develop threshold planning quantities

for each of the 402 chemicals on the list

of extremely hazardous substances and

publish interim final quantities

simultaneously with publication of the

list. The threshold planning quantity is

used to trigger reporting by facilities to

the State emergency response

commission. Any facility that has one or more of the chemicals on the list of

extremely hazardous substances in

quantities equal to or greater than the

threshold planning quantity must - provide notification to State emergency

response commissions by April 17, 1987.

Section 302 specifies that the planning

quantities may be based upon classes or categories of chemicals. If the Agency

fails to develop threshold planning

quantities for the chemicals on the

extremely hazardous substances list, a quantity of two pounds is automatically

established for each chemical.'

b. Development of Threshold Planning

Quantities: For many substances the

potential for a serious accidental release

resulting from an on-site quantity of two

pounds is extremely remote. Therefore,

threshold planning quantities of two

pounds for all of the extremely

hazardous chemicals could result in

many unnecessary notifications,

diverting the attention of emergency

planners from facilities which may be of

higher concern. Because the Agency believes that the

two pound threshold planning quantity

for all 402 substances would overwhelm

local emergency planning efforts and

would not relate to the endangerment

posed by individual substances, it is

today establishing threshold planning

quantities in lieu of the statutory level.

The threshold planning quantities are designed to help State and local officials

identify those sites where there is a

greater potential for harm to the

surrounding community if a release

were to occur, thereby focusing

resources on the priority emergency

planning problems.

c. Methodology: The Agency

considered four alternative approaches

for development of the threshold

planning quantities:

Approach 1. Specific Quantity

Prediction. Under this approach the

Agency would determine the specific

quantity of each chemical that, if

accidentally released, would result in

significant acute health effects at a fixed

distance from the release site.

Approach 2. Dispersion/Toxicity

Ranking Method. Under this approach the Agency would assign chemicals to

threshold planning quantity categories based on an index that accounts for the

toxicity, the potential to become

airborne, and the downwind dispersion of each chemical in an accidental

release.

Approach 3. Toxicity Ranking

Method. Under this alternative the

Agency would assign categories of

threshold planning quantities based

solely on a toxicity index.

Approach 4. Two Pound Quantity for All Chemicals. Under this option, the

default quantity of two (2) pounds would

be used.

After considerable analysis, the

Agency has chosen to develop threshold

planning quantities using Approach 2.

The methodology used in each approach

is presented below along with a

discussion of the approaches and the

reasons why the Agency believes

Approach 2 is the most appropriate for

establishing threshold planning quantities. For details on the

methodologies employed, refer to the

Threshold Planning Quantities

Technical Support Document, which is

available in the public docket for this

rule. Comments are solicited on the

various approaches and the

methodologies. Information on

alternative approaches also is being sought by the Agency for consideration

in the development of a revised final

rule.

Methodology for Approach 1-Specific Quantity Prediction

The methodology for this approach is

derived from the site specific guidance developed for the CEPP Interim

Guidance. The methodology consists of

initially determining a maximum shortterm exposure concentration level in air

("level of concern") for each chemical

that would not lead to serious health

effects. The quantity of each chemical

that would have to be released to the air

to reach the "level of concern" is

estimated using techniques for

atmospheric dispersion and assessing

physical/chemical properties.

This approach is a complex process

designed to provide a specific threshold

planning quantity for each of the 402

extremely hazardous substances. This

section discusses the derivation of

levels of concern, assumptions,

concerning distance and release

circumstances, and the dispersion

modeling techniques used in the

development of the threshold planning

quantities under this approach.

To perform this analysis, a level of

concern must be selected for each

chemical, a representative distance from

the release site to the exposed

population must be determined, and the

conditions and modeling techniques for

release and dispersion must be selected

for each chemical. A level of concern was considered to

be the maximum concentration of an

extremely hazardous substance in air

that will not cause serious irreversible

health effects in the general population

when exposed to the substance for

relatively short duration. At present, no

such exposure levels have been

established specifically for the general

public. The National Academy of

Sciences and others have been

developing guidelines for estimating

such levels for toxic chemicals.

However, at this time, values for only a

few chemicals have been established.

In lieu of a value developed for the

general public, the Agency has

identified a surrogate measure of such

an exposure level. This approximation is

the Immediately Dangerous to Life and

Health (IDLH) level which is available

for 92 of the chemicals on the list of

extremely hazardous substances. This

level established by the National

Institute for Occupational Safety and

Health (NIOSH) represents 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.

The Agency recognizes that the IDLH

may have some limitations as a measure

for protecting the general population.

First, the IDLH is based upon the

response of a healthy, male worker

population and does not take into

account exposure of more sensitive

individuals such as the elderly, children,

or people with various health problems.

Second, the IDLH is based upon a

maximum 30 minute exposure period

which may not be realistic for

accidental airborne releases. Third, the

IDLH may not indicate the

Federal Register / Vol. 51, v
41576 Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations

concentration that could result in

serious but reversible injury. Based on

these considerations, the development

of more appropriate chemical emergency

exposure levels for the general public

has been identified as a high priority for

the Agency.

However, the IDLH value, or an

estimation of this value for substances

that do not have a published IDLH,

appears at present to be the best

approximation of a level of concern

available for planning purposes. IDLH

values for those substances with

published values were used in the

calculations for establishing threshold

planning quantities.

Levels of concern were estimated

from acute animal toxicity test data for

the substances that did not have

published IDLH values.

In these instances, the concentration

used to establish threshold planning

quantities is determined from LCso LCLo.

LDso, or LDL data. The following

equations show how these data are

converted to air concentrations to

approximate the IDLH level: (1)

Estimated level of concern = LCo X

0.1; (2) estimated level of concern =

LCLo; (3) estimated level of concern

LDso x 0.01; and (4) estimated level of

concern = LDLO x 0.1. As new

information and methodologies become

available in the future, the level of

concern and the value derived for

chemicals on the list should be reevaluated.

A second critical input to the analysis

is the distance from the source of the

release to the exposed population. For

the purposes of establishing planning

quantities, the Agency chose a distance

of 100 meters (330 feet) to represent the

distance from a source inside a chemical

facility to the point where the

community might be exposed. The

Agency believes that this distance is

representative of the point at which the

community might first be impacted for

most situations. The Agency recognizes

that it may be shorter than that found at

large manufacturing facilities,

(particularly those that also have a

"buffer zone") or farther than that found

at facilities located within urban

centers. For example, an informal

survey of chemical facilities in the

Kanawha Valley (West Virginia) by the

National Institute for Chemical Studies

in Charleston, West Virginia, showed

that the distances between storage

vessels and residential housing may be

as close as 25 feet (Meyer, 1986).

However, there are limitations

associated with atmospheric dispersion

modeling techniques at distances less

than 100 meters. Additionally, the

Netherlands Safety Report Legislation

indicates that releases that travel more

than 100 meters are judged to be major accidents (Van Deputte, 1982).

Once the level of concern for each

chemical was determined and a fixed

distance was established, dispersion

modeling techniques were used to

calculate the quantity of airborne

chemical required to generate the level

of concern at 100 meters. Although

techniques have long been available and

used to address air pollution and

nuclear fallout, the uses of dispersion

modeling techniques to simulate the

behavior of chemicals released under

accidental conditions for very short time

spans are largely still under

development. The Agency's comparison

of the several available dispersion

modeling techniques is described in the

Threshold Planning Quantities

Technical Support Document available

in the public docket for this rule.

A third critical aspect in the

development of the methodology Is the

assumption made concerning the release

of the chemical. An accidental release

could be caused by a number of events

such as a process upset (e.g. runaway

reactions, temperature or pressure

excursions leading to release), equipment failures (such as pipe rupture,

equipment seal failure, valve leaks),

handling accidents (such as overfilling

containers and puncturing drums with a

forklift), or fires and explosions that

affect nearby containers or storage vessels of toxic substances. The release

scenario generally determines the nature

of the emission source and source

strength which are critical to the

dispersion consequences. Therefore

analysis of potential release scenarios in

complex and critical to the outcome.

The chemicals on the list were

segregated by ambient physical state

and grouped as gas, liquid or solid.

Gases and liquids represent about half

of the 402 chemicals on the list; the

remainder are solids. In analyzing the

chemicals released, scenarios were

developed as follows: Gases were

assumed to be stored under pressure

such that if a leak, rupture or process

upset occurred, a relief valve would

open or a rupture would occur, causing a

gas jet to be released. Liquids were

assumed to be spilled on the ground at

ambient conditions and allowed to

volatilize. Liquified gases were also

evaluated. Because neither of the two

release scenarios above are appropriate

for solids unless the solids are handled

in molten or vaporized state, solids were

assumed to be dispersed in powered form as an aerosol by some mechanical

means (e.g. filtration unit failure, dust

explosion, or other explosion) because

this represents a more realistic

emergency release scenario. The

sublimation of a solid as a result of a

spill was considered and rejected

because volatilization of solids is so

slow that it does not present an

emergency release hazard.

Advantages and Limitations of

Approach 1

Approach 1 was designed to

determine a specific individual quantity

for each chemical for purposes of

emergency planning. The quantities

calculated using this approach ranged

from below one pound (for certain

extremely toxic gases) to millions of

pounds (for relatively involatile

substances). The apparent rigor of the

methodology, however, is somewhat

misleading due to the uncertainty in the

level of concern (IDLH), the release

scenarios selected, the source strength

inputs, and the ability to model both the

release and dispersion. Also, most

dispersion techniques are compatible

with only a limited number of the many

potential release events that could

occur, the Agency has no data to show

whether these events represent typical

or worst case situations.

Assumptions used with the modeling

techniques also cause wide variations in

the results. In the case of gases,

variations of several orders of

magnitude are possible depending on

the pressure at which the gas is stored,

size of the release opening, density and

velocity of the escaping gas. An

accidental release is an extremely

dynamic event. The dynamics

associated with accidental releases are

not considered in this analysis since

little information is available for the

potential release conditions likely for

the chemicals on the list.

Finally, even if the Agency was fully

confident of the release scenario,

emission source modeling and

dispersion techniques, a number of key

parameters in the analysis are sitespecific. These parameters include the

distance from the source to the

community or fenceline, the way in

which the chemical is actually handled

at the facility (e.g., at high temperatures

and pressures, refrigerated, etc.), the

topography of the area around the site,

and prevailing meteorological conditions

which can cause wide variation in the

dispersion of airborne chemicals. In the

absence of a valid empirical data base,

the Agency must make assumptions

concerning "reasonable" or "credible"

characteristics of these site-specific

factors. These assumptions are

influenced by modeling capabilities as

well as general knowledge of chemical

manufacturing and processing

41576 Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations
Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations 41577

operations and greatly affect the

accuracy of results.

For these reasons, the Agency has not

used this approach to establish the

threshold planning quantities in today's

rule. However, because the selected

methodology (Approach 2) relies on

Approach I technical analyses, the

Agency seeks comments and

suggestions on the methodology used

here for revision prior to issuance of a

revised final rule.

Approach 2-Dispersion/Toxicity

Ranking Method

The methodology for this approach

makes use of the same technical

analyses used in Approach 1 but uses

them only to produce a ranking of the

chemicals according to their potential to

become airborne, dispersion potential

and toxicological properties. This

approach provides a basis for relative

measures of concern rather than

absolute values. Under Approach 2, the

levels of concern are used as an index of

toxicity, and physical state and

volatility are used to assess their

dispersion potential. The two indices are

combined to produce an overall risk

score or "ranking factor". Once the

chemicals have been ranked, categories

of quantity are assigned based on their

relative ranking. The lowest rank

(highest risk) are assigned low

quantities and the highest rank (lowest

risk) are assigned higher quantities.

To achieve this, the list of chemicals is

again segregated by ambient physical

state such as gas, liquid or solid. An

index value is obtained by assuming

that the level of concern is divided by

the factor V, which represents the extent

to which the material can become

airborne and dispersed:

Index=Level of Concern/V

where V is the extent to which the

chemical can become airborne. V is

assumed to be I for chemicals that are

gaseous at ambient conditions and for

solids in powder form (e.g., flour, talc),

that is, in an accidental release all of the

chemical could become airborne. For

liquids, V represents the extent of

volatilization of a spilled quantity of

liquid and is estimated by knowing the

chemical's molecular weight and vapor

pressure. See Attachment I at the end of

this preamble for a derivation of the

equations used to estimate V.

Once all the chemicals have been

ranked, quantities are assigned to

groups of chemicals on the list. In the

Agency's evaluation of all of the

chemicals, only nickel carbonyl is

assigned a quantity of "any amount"

and must be reported in any quantity

because of its extremely high acute

toxicity. Other chemicals with a low

index factor, based on the Agency's

technical review, are assigned a

quantity of two pounds, the default

quantity given by the Congress. With the

exception of nickel carbonyl, it is

believed that the two-pound quantity

represents a reasonable lower limit for

the most extremely hazardous

substances on the list. Chemicals with

the highest index factors (or rank) were

assigned a threshold planning quantity

of 10,000 pounds. This ensures that any

facility with as much as a tank wagon or

truck load of any extremely hazardous

substances would be required to notify

the State commission. Between the

limits of two pounds and 10,000 pounds,

chemicals were assigned to intermediate

categories of 100, 500 or 1,000 pounds

based on order of magnitude ranges in

the index values. The selection of the

intermediate categories was based on

standard container sizes between two

and 10,000 pounds. In summary, the

allocations were as follows:

Index value: Meshold quantity ({b)

<Ix10"2 . . . . . . . . . . . . . . . . . . . . 2

>10- 2 to <10- k ................................... 100

>10- 1 to < 1 ...................... I ............... 500

>1 to <10 ............................................ 1,000

>10 ........................................................ 10,000

Advantages and Limitations of

Approach 2

The methods utilized in constructing

the exposure and toxicity indices for

Approach 2 are based upon, and

therefore share the limitations of the

methodologies utilized in Approach 1. In

particular, NIOSH's IDLH or the

Agency's estimated level of concern is

an imperfect measure or an

approximation of acute toxicity for

emergency release situations involving

the general public. In addition, the

dispersion index is based upon specific

release event assumptions. Changes in

such assumptions could lead to changes

in the rankings to a certain degree.

Nevertheless, the Agency believes that

this approach provides a consistent

relative ranking of the extremely

hazardous substances.

The selection of the particular cutoff

values for the quantities is based wholly

on the relative ranking among all of the

substances on the list. Since this is a

relative ranking scheme, there is no

precision associated with the numbers

and they should not be construed as "safe" levels. Because the Agency

cannot evaluate every release scenario,

it is possible that a serious event could

occur with any quantity lower than the

threshold planning quantity given by

this approach. Conversely, some

chemicals may be unlikely to cause

serious events even at quantities

significantly above their thresholds.

However, the Agency believes that this

approach yields threshold planning

quantities which will focus initial

community planning on those situations

which present the greatest risk.

Methodology for Approach 3--Toxicity

Ranking Method

This approach is similar to Approach

2 except that the chemicals on the list of

extremely hazardous substances are

ranked using only their level of concern

as an index. As in Approach 2, the

chemicals are assigned quantities

ranging from any quantity for nickel

carbonyl to 10,000 pounds with

intermediate categories of 100, 500, and

1,000 pounds based upon a ranking of

level of concern values.

Advantages and Limitations of

Approach 3

By ignoring the potential for the

chemical to become airborne, this

approach simplifies the analysis but it

may also distort local planning

priorities. Although the Agency cannot

assess all of the ways in which releases

can occur, it is clear that physical state

and vapor pressure greatly influence

how much of the chemical actually gets

into the air. Therefore, the Agency

believes that consideration of the

potential should be included in the

development of a threshold planning

quantity.

Approach 4-Default to 2 Pounds

Under this approach, EPA could take

no action and allow the statutory

thresholds to become effective.

Advantages and Limitations of

Approach 4

A two pound quantity for each

chemical is simple and straight-forward

and ensures notification by facilities

handling those chemicals that are

deemed extremely hazardous in nature.

However, it again ignores the potential

for the chemical to actually become

airborne, distorts local planning

priorities and may cause local planning

authorities to be overburdened by

unnecessary notifications.

Conclusions

The Agency believes that Approach 2

is most appropriate for development of

the threshold planning quantities

because the quantities developed

depend primarily on the toxicity of the

chemical (level of concern) and degree
41578 Federal Register / Vol. 51, No. 221 / Monday, November 17, 1986 / Rules and Regulations

to which the chemical will become

airborne; factors which are very

important in deciding which chemicals

are the most important from an

emergency planning standpoint. The

potential for the chemicals to become

airborne is not considered in Approach

3. Although Approach I also addresses

these factors, the apparent rigor of this

methodology is not supported by the

uncertainty of the assumptions and the

models which must be applied.

Therefore, the planning quantities

derived from Approach 1 suggest a level

of accuracy or precision that cannot

reasonably be relied upon.

Technical support documents, which

contain additional information on the

approaches presented here and the

outcome of applying the approaches, are

available in the public docket. A list of

these documents is set forth in

Attachment II. Approach I provides a

much broader range (from less than one

pound to over one million pounds,

depending upon the assumptions and

models used) than the other approaches.

The Threshold Planning Quantity

Technical Support Document includes

the results of applying Approach 1, using

varying release scenarios and

assumptions, for a representative group

of chemicals. Approaches 2 and 3 result

in a narrower range, with five planning

quantity categories, and "any quantity"

planning quantity for nicket carbonyl.

Of these two latter approaches, only

Approach 2 considers the degree to

which the chemical will become

airborne.

The Agency believes that limited

State and local resources should be

focused on those substances that

potentially will cause the greatest harm

should an accidental release occur. The

quantities developed in Approach 2

meet the objective such that those that

are most likely to cause serious

problems (extremely toxic gases, solids

likely to be readily dispersed, or highly

volatile liquids) have lower quantities

that those that might be toxic but are not

likely to be released to the air.

The Agency applied the ranking

methodology described in Approach 2 to

the 402 extremely hazardous substances.

Recognizing that a strictly mechanical

application of this approach could lead

to errors based on specific

characteristics of individual chemicals,

the Agency then subjected each

chemical to a limited additional review

to evaluate the technical reasonableness

of the assignments. The threshold

planning quantity allocations

determined by the ranking methodology

were examined and where appropriate

changes to higher or lower threshold

classifications were made based upon

other toxicity data, rapid absorption

chemical reactivity, specific handling,

formulation, and use considerations and

related factors. For example, sarin and

tabun, which were assigned to the 100

pound category by the methodology

applied, were assigned to the two pound

category because information on their

toxicity suggested that they may be even

more toxic under conditions of an

accidental release than is indicated by

the estimated level of concern. Thirty

chemicals were reassigned based on this

review. The rationale for each such

decision is being included in the public

docket for this rulemaking. Finally one

chemical, nickel carbonyl, had a ranking

value so low the Agency decided that

any quantity could be a potential

problem. The threshold for this chemical

was therefore set at "any quantity".

Further, in the case of Approach 2, it

was decided that if a chemical in solid

form is not handled or stored as a

powder at a site and it is not reactive

with air or water to become airborne or

to form airborne toxic products or byproducts (e.g., sodium cyanide), then it

would be assigned a quantity of 10,000

lb. Although the Agency cannot identify

which chemicals are stored or handled

in powder form, it has identified 15

substances that are reactive with water

or air which cannot be assigned a

threshold planning quantity of 10,000

pounds regardless of their physical form.

These substances are identified in the

list of extremely hazardous substances

and are discussed in the Technical

Support Document on Reactive Solids,

which is available in the public docket

for this rule. The Agency solicits

comments on whether nonreactive

solids not handled as a powder should

be deleted from the list of extremely

hazardous substances, instead of

assigning a default value of 10,000

pounds.

Many of the extremely hazardous

chemicals are transported, used and

stored in formulated products, which

contain mixtures of chemicals. The

potential hazard associated with

extremely hazardous chemicals in

mixtures depends on the concentration

of the material as well as many factors

specific to the composition of the

formulations. The Agency has noted in

the threshold planning quantities list,

one case where it believes that common

commercial formulations should not be

considered for the purpose of

notification under this regulation. In the

case of hydrogen peroxide, the Agency

does not believe that there is cause for

concern with aqueous concentrations of

equal to or less than 52 percent and

designates this exception on the list of

extremely hazardous substances. The

Agency solicits comments on this

concept, which is discussed in more

detail in the technical document which

addresses respcnse to public comments

on the CEPP interim guidance.

In all other cases, and in the absence

of more specific information, the Agency

believes that mixtures of formulations

containing one (1) percent or more of an

extremely hazardous substance should

be evaluated for notification purposes.

This means a mixture containing less

than 1% of an extremely hazardous

substance need not be factored into the

calculation of the threshold planning

quantity. The rationale for the 1% rule is

the low probability of the release of

such a mixture delivering the threshold

planning quantity of the extremely

hazardous substance to the

environment. OSHA has selected this

cutoff value of its Hazard

Communication Rule (29 CFR 1900.1200)

for all hazards except carcinogens.

In evaluating whether to notify for

mixtures, facility owners or operators

should compare the appropriate

threshold quantity with the weight of the

extremely hazardous substance in the

mixture. For example, if the threshold

for a given chemical on the list is 100

pounds and that chemical is 20 percent

by weight of a mixture, notification

would be necessary if 500 pounds or

more of that mixture is present at a

facility. Note, however, that no such

deminimis exemption exists for

emergency release reporting under

section 304.

The Agency seeks comments on the

methodology chosen to determine

threshold planning quantities.

Specifically, the Agency seeks

comments on:

-Whether the ranking methodology

selected (Approach 2) is appropriate

for the categorization of the extremely

hazardous substances by threshold

quantity, and if not, which other

approach might be preferable and

why.

-Whether the specific toxicity and

exposure indices, the IDLH (or

calculated level of concern), and V,

respectively, chosen are appropriate

for constructing the index.

-Whether the Agency has set the

threshold planning quantities for the

extremely hazardous chemicals

(ranging from any to 10,000 pounds)

too high or too low in order to provide

state and local planning authorities

the information with which to

effectively begin their emergency

planning activities.
No. 221 / Monday, November 17, 1986 / Rules and Regulations 41579

-Whether it is appropriate to establish

a percentage below which extremely

hazardous components of mixtures do

not have to be considered and, if so,

whether one percent or some other

percentage is an appropriate cutoff

level.

-Whether the chemical specific

quantity adjustments to the

determinations made under Approach

2 properly considered the individual

characteristics of the adjusted

chemicals, and whether other

chemicals on the list also require

quantity adjustments.

-Whether assigning threshold planning

quantities of 10,000 pounds to nonpowder, non-reactive solids

adequately addresses concerns for

these materials.

-Whether it is appropriate not to

consider certain common commercial

formulations for purposes of

notification under this regulation and

whether the designated reporting limit

of greater than 52 percent aqueous

hydrogen peroxide is appropriate.

C. Statutory Requirement of Interim

Final Rulemaking and Solicitation of

Public Comment

Section 302 of Title III of SARA

requires the Administrator to publish a

list of extremely hazardous substances

within 30 days of enactment. The initial

list is required to be the same as the list

of substances published in November,

1985 by the Administrator in Appendix

A of the Chemical Preparedness

Program Interim Guidance. In addition,

section 302 specifically requires the

Administrator to publish interim final

regulations establishing a threshold

planning quantity for each substance on

the list, and to initiate a rulemaking to

revise these threshold planning

quantities. Failure to establish the

threshold planning quantities results in

statutorily established threshold

planning quantities of two pounds.

Although this rule is statutorily

required to be effective immediately, the

Agency is also, soliciting comment on all

aspects of today's rule. In a companion

proposed rule published elsewhere in

today's Federal Register, the Agency is

specifically initiating a rulemaking to

revise today's rule as appropriate in

response to public comment.

In addition, certain portions of today's

rule have previously received the benefit

of public scrutiny and comment. At the

time the list of 402 extremely hazardous

substances was first published by the

Agency, it was part of a voluntary

.program to encourage localities to begin

the process of planning for chemical

contingencies occurring in their

communities. Appendix A of the

Chemical Emergency Preparedness

Program Interim Guidance document

was made public in November, 1985.

That guidance identified those

substances for which it was not enough

to merely focus attention on cleanup of

releases. Rather, because these

substances, upon release, posed

immediate and serious threats to the

surrounding community, emergency

planning and release prevention was

necessary for effective protection of

human health and the environment.

At the time of publication, comments

were requested on the methodology for

establishing the CEPP list. EPA received

comments on the toxicity data used for

specific chemicals, and revisions based

on those comments are discussed in

section II.B.2.c. above. A summary of

these comments and the Agency's

response has been incorporated into the

public docket for this rule.

Today we are requesting comments on

all aspects of this rule and are

specifically soliciting comments on the

criteria for establishing the extremely

hazardous substance list, the threshold

planning quantities and the

methodologies for establishment of the

quantities.

Comments must be submitted within

45 days of the publication of this

regulation in the Federal Register. Upon

completion of the 45 day comment

period, the threshold planning quantities

and supporting regulations will be

finalized in a subsequent final rule as

required by section 302, using the

comments received as guidance in

revision of this interim final rule. The

comment period is shorter than that

provided for many Agency rules, but is

essential in order to allow a final rule to

be published before May 17, 1987, when

facility notifications are due.

III. Relationship to CERCLA

A. Relationship of Title III to CERCLA

Title III is a free-standing Title within

SARA and thus is separate from, though

closely related to, CERCLA. Because the

Agency's CEPP effort was developed

originally under CERCLA and because

Title III emergency response and

planning are closely linked to the

hazardous substance release response

program under CERCLA, the authorities

and requirements created by Title III

will be largely incorporated into the

existing National Contingency Plan,

established under CERCLA section 105.

B. Relationship of This Rulemaking to

the National Contingency Plan

This rulemaking is a new Subpart I

within the existing National Oil and

Hazardous Substances Pollution

Contingency Plan (NCP (40 CFR 300).

The NCP provides for an efficient,

coordinated and effective response to

discharges of oil and releases of

hazardous substances, pollutants and

contaminants in accordance with the

authorities of CERCLA and section 311

of the Clean Water Act. The NCP

establishes the national organization,

policy and procedures for preparedness

and response to environmental

incidents. The Agency is now in the

process of developing a rulemaking to

comprehensively revise the NCP to

incorporate other changes under SARA

and will evaluate placement of Title Ill

rules.

C. Relationship of this Rule to CERCLA

Section 103 Reporting Requirements

Under section 103 of CERCLA, .any

person in charge of a facility at which

there is a release of a hazardous

substance as defined in CERCLA section

101(14) equal to or in excess of its

reportable quantity must report

immediately to the National Response

Center. The National Response Center

will then alert the appropriate federal

emergency response personnel of the

release. This notification includes

transportation incidents as well as fixed

facility emergencies.

The notification to the State

emergency response commission under

section 302 is not triggered by a release

incident but rather by the presence of

certain quantities an extremely

hazardous substance at a facility. No

release or event of any kind is required

for a section 302 report. This notification

is an initial action in a process that

culminates in the development of

community emergency response plans.

Section 304 in contrast, establishes

reporting requirements similar to

CERCLA Section 103 release reporting.

However, instead of requiring

notification only to the National

Response Center when certain

quantities of certain chemicals are

released, facilities must under section

304 also notify State and local

emergency response officials of these

releases.

A comparison of the reportable

quantities established by the Agency

under CERCLA for the purposes of

emergency response with the threshold

planning quantities in today's rule

indicates that the quantities established

under these lists are not entirely

comparable. In fact, 26 adjusted

reportable quantities were higher than

the threshold planning quantities for the

same extremely hazardous substance.

As a result, emergency planning would

be required for an amount on the plant

-Federal Register / Vol. 51,
41.1;80 Federal Revister / Vol. 51. No. 221 / Monday, November 17, 1986 / Rules and Regulations

site which, if entirely released, would

not require a reporting to the National

Response Center or to the State

commission. This has occurred as a

result of the use of two different

approaches for establishing reportable

quantities and threshold planning

quantities. Unlike CERCLA reportable

quantities, the threshold planning

quantities are based upon exposure

potential. CERCLA reportable quantities

are based solely on the intrinsic

chemical and physical properties, or

toxicity, of a hazardous substance.

During rulemakings to revise the final

rule and to adjust reportable quantities

under CERCLA and Title 11, the Agency

intends to evaluate and address, as

appropriate, inconsistencies between

the two methodologies, the underlying

data base of each, and the resulting

quantities.

IV. Regulatory Analyses

A. Regulatory Impact Analysis

Rulemaking protocol under Executive

Order 12291 requires that regulations be

classified as "major" or "non-major" for

purposes of review by the Office of

Management and Budget. According to

E. 0. 12291, major rules are regulations

that are likely to result in (1) An annual

adverse (cost) effect on the economy of

$100 million, (2) a major increase in

costs or prices for consumers, individual

industries, federal, state, or local

government, or geographical regions, or

(3) significant adverse effects on

competition, employment, investment,

productivity, innovation, or the ability of

United States based enterprises in

domestic or export markets.

Because this rule was required by

statute to be published in 30 days no

further economic or regulatory impact

analysis could be conducted by the

Agency prior to the publication of this

interim final rule. However, analyses of

economic and regulatory impact will be

completed for the revised final rule.

B. Regulatory Flexibility Analysis

The Regulatory Flexibility Act of 1980

requires that an analysis be performed

for all rules that are likely to have a "significant impact on a substantial

number of small entities." Based on the

limited time available, the Agency did

not conduct a formal flexibility analysis.

However, the Agency has considered

the impact on small entities and does

not believe that this rule will have

significant impact on a substantial

number of small entities.

C. Paperwork Reduction Act

The reporting and notification

requirements contained in this rule have

been approved by the Office of

Management and Budget (OMB) under

the provisions of the Paperwork

Reduction Act of 1980, 44 U.S.C. 3501 et

seq. and have been assigned OMB

control number 2050-0046.

Attachment I

Technical Details for Approach 2

Determination of the Threshold

Planning Quantity

In Approach 2, the index for ranking

the chemicals on the list is:

Index=Level of Concern/V

where V represents the extent to which the

chemical can become airborne and

dispensed. For gases and solids V equals

one, meaning all of the chemical once released can be potentially airborne. For

liquids, V is calculated by estimating the

rate of volatilization (mass vaporized per

time) per mass of liquid spilled. The V

may be generated as follows using

equations from Clements (1981] (see also

TRC, 1986)

The evaporation rate of a liquid into

stagnant air may be estimated by:

G = (1.74 X10- 4 MKAP)/(RT)

where G is the generation rate in pounds/

minute; M, the molecular weight; K, mass

transfer coefficient [cm/sec); A, surface

area of the spill (cm2

); P is the vapor

pressure of the chemical (mm Hg); R is

the Universal Gas Constant (82.05 atm

cm3

/g-mole 'K) and T is the temperature

of the liquid in *K. The mass transfer

coefficient may be approximated by

referencing the unknown chemical to

water:

K=0.83 (18/M) 0,33

Combining equations gives:

G= (3.78X10 - 4 M21 3 A P)/(R T)

The surface area of a spill (or pool) is

primarily a function of spilled quantity

provided the spill occurs on a flat, nonabsorbing surface. The depth of the pool

is assumed to be 1 cm; although if the

area around a storage vessel is diked or

not flat where puddling could take

place, deeper levels could occur for the

same surface area of spilled material. In

the absence of specific information

about the size of diked area for each

liquid, we assume that the spill is 1 cm

deep and has density about that of

water (1 gm/cm3):

Area (cm 2

)=454 (gm/Jb) Q (lb) / 1 (gm/cm3 )

1 (cm) = 454 Q

Substituting and assuming the liquid

is at its boiling temperatures (P=760,

T>boiling point):

G/Q=V=1.6M/0- 6 o / (T+273)

where G/Q represents the rate of

volatilization per mass of liquid spilled.

Note that V was estimated for liquids at

their boiling point rather than at ambient

temperatures. Conditions during

accidental releases are likely to vary and

to involve heat (e.g. fires, exothermic

runaway reactions or reactions with air

or water) causing more rapid

volatilization of the liquid. The Agency

recognizes that spills at ambient

temperatures are also likely and that the

rate of volatilization may be impacted by

heat from the surroundings, subcooling

due to evaporation and flashing from

superheated conditions. However, for

purposes of developing a relative ranking

between substances volatilization at

boiling points was utilized and

consideration of other conditions for all

chemicals is not expected to greatly

reorder the ranking of chemicals.
