RMP List Rule Change
Effective January 6, 1998

The Environmental Protection Agency (EPA) has
modified the rule listing regulated substances and
threshold quantities under section 112(r) of the
Clean Air Act. EPA is deleting the category of
Division 1.1 explosives (as listed by DOT) from the
list of regulated substances. Regulated flammable
substances in gasoline used as fuel and in naturally
occurring hydrocarbon mixtures prior to initial
processing are exempted from threshold quantity
determinations, and the provision for threshold
determination of flammable substances in a mixture
is clarified. The definition of stationary source is
modified to clarify the exemption of transportation
and storage incident to transportation and to clarify
that naturally occurring hydrocarbon reservoirs are
not stationary sources or parts of stationary
sources. In addition, EPA is clarifying that the
Chemical Accident Prevention Provisions do not
apply to sources located on the Outer Continental
Shelf. EPA believes these changes will better focus
accident prevention activities on stationary sources
with high hazard operations and reduce duplication
with other similar requirements.

DATES: This rule is effective January 6, 1998.

RMP & Small Business

EPA has developed a brochure that introduces small
businesses to RMP requirements. The brochure
answers such questions as:

•	What is the Risk Management Program all
about and why might I be covered?

•	Why is the Risk Management Program
important to me?

•	When do I need to comply and how do I do it?

•	Where can I get help?

This brochure is written in very understandable
terms. A copy can be obtained at
http://www.epa.gov/swercepp/pubs/article.html or
from EPA's Hotline at 1-800-424-9346.

RMP*Submit and RMP*lnfo
Fact Sheet Available

EPA has also developed a fact sheet on the
RMP* Submit and RMP*Info systems.
RMP*Submit will be used by covered sources to
submit their risk management information to EPA.
RMP*Info, an internet-based database, will be used
by the public and local agencies to retrieve the
information for their own purposes. The fact
sheet is available from the EPA Hotline or
http://www.epa.gov/swercepp/whatnew.html

General Duty Clause Q &
A's ~ Everyone's Covered

Regardless of whether a stationary source must
comply with the Accidental Release Prevention
Requirements (RMP Rule), it is subject to CAA
112(r)(l) or the General Duty Clause if it uses
a hazardous substance in any amount.

The General Duty Clause reads as follows:

SEC. 112. HAZARDOUS AIR POLLUTANTS....
(r) Prevention of Accidental Releases.-
(1) Purpose and general duty.-It shall be the
objective of the regulations and programs
authorized under this subsection to prevent the
accidental release and to minimize the
consequences of any such release of any substance
listed pursuant to paragraph (3) or any other
extremely hazardous substance. The
owners and operators of stationary sources
producing, processing, handling or storing such
substances have a general duty in the same

manner and to the same extent as section 654,
title 29 of the United States Code, to identify
hazards which may result from such releases
using appropriate hazard assessment techniques, to
design and maintain a safe facility taking such steps
as are necessary to prevent releases, and to
minimize the consequences of accidental releases
which do occur. For purposes of this paragraph,
the provisions of section 304 shall not be
available to any person or otherwise be
construed to be applicable to this paragraph.
Nothing in this section shall be interpreted,
construed, implied or applied to create any
liability or basis for suit for compensation for
bodily injury or any other injury or property
damages to any person which may result from
accidental releases of such substances.

Question: What is the general duty clause
under CAA §112(r)(l)?

Answer: The CAA general duty clause directs
owners and operators of stationary sources to
identify hazards that may result from accidental
releases, to design and maintain a safe facility, and
to minimize the consequences of releases when they
occur.

(CAA Q&A Database, October 1996)

Question: For CAA section 112(r)(l), General
Duty, what are the chemicals that are covered?

Answer: There is no specific list of substances
which subject a stationary source owner or operator
to the general duty provisions. The general duty
provisions apply to owners and operators of all
stationary sources which have any " extremely
hazardous substances". Extremely hazardous
substances are not limited to the list of regulated
substances listed under section 112(r), nor the
extremely hazardous substances under EPCRA
§302 (40 CFR Part 355, Appendices A and B).

Although there is no definition for extremely
hazardous, the Senate Report on the Clean Air Act
provides criteria EPA may use to determine if a
substance is extremely hazardous. The report
expressed the intent that the term "extremely
hazardous substance" would include any agent
"which may or may not be listed or otherwise
identified by any Government agency which may as
the result of short-term exposures associated with
releases to the air cause death, injury or property
damage due to its toxicity, reactivity, flammability,
volatility, or corrosivity" (Senate Committee on
Environment and Public Works, Clean Air Act
Amendments of 1989, Senate Report No. 228, 101st
Congress, 1st Session 211 (1989) - "Senate
Report").

As the Senate makes clear, "the release of any
substance which causes death or serious injury
because of its acute toxic effect or as a result of an
explosion or fire or which causes substantial
property damage by blast, fire, corrosion or other

reaction would create a presumption that such
substance is extremely hazardous." Senate Report
at 211. Revisions to the list of regulated substances
under CAA 112(r) do not affect the applicability of
the general duty provisions.

(CAA Q&A Database, May 1997)

Question: Does the exemption at 40 CFR
68.125 for "ammonia used as an agricultural
nutrient, when held by farmers" apply to the
CAA Section 112(r)(l) general duty clause?

Answer: No. The exemption for ammonia held by
farmers for use as fertilizer applies only to the
provisions of the risk management program
regulations at 40 CFR Part 68. The general duty
requirement is statutory rather than regulatory and is,
therefore, not subject to the regulatory exemption at
40 CFR 68.125.
