The Emergency Planning and Community Right-to-Know Act
On December 4, 1984, methyl isocyanate, an extremely toxic chemical escaped from a Union
Carbide chemical plant in Bhopal, India. Thousands died and many more were injured. Some
suffered permanent disabilities. Approximately six months later, a similar incident occurred at the
Institute, West Virginia. These two events raised concern about local preparedness for chemical
emergencies and the availability of information on hazardous chemicals.
In response to these concerns, Congress passed the Emergency Planning and Community Right-to-
Know Act (EPCRA) in 1986. EPCRA establishes requirements for federal, state and local
governments, Indian tribes, and industry regarding emergency planning and "Community Right-to-
Know" reporting on hazardous and toxic chemicals. The Community Right-to-Know provisions help
increase public's knowledge and access to information on chemicals at individual facilities, their
uses, and releases into the environment. States and communities, working with facilities, can use the
information to improve chemical safety and protect public health and the environment.
What Are SERCs, TERCS, and LEPCs?
The Governor of each state designated a State Emergency Response Commission (SERC).
The SERCs, in turn, designated about 3,500 local emergency planning districts and appointed
Local Emergency Planning Committees (LEPCs) for each district. The SERC supervises and
coordinates the activities of the LEPC, establishes procedures for receiving and processing
public requests for information collected under EPCRA, and reviews local emergency response
plans.
The Chief Executive Office of the Tribe appoints the Tribal Emergency Response Commissions
(TERCs). TERCs have the same responsibilities as the SERCs.
The LEPC membership must include, at a minimum, local officials including police, fire, civil
defense, public health, transportation, and environmental professionals, as well as
representatives of facilities subject to the emergency planning requirements, community
groups, and the media. The LEPCs must develop an emergency response plan, review it at
least annually, and provide information about chemicals in the community to citizens.
What Does EPCRA Cover?
EPCRA has four major provisions:
•	Emergency planning (sections 301-303),
•	Emergency release notification (section 304),
•	Hazardous chemical storage reporting requirements (sections 311-312), and
•	Toxic chemical release inventory (section 313).
Information collected from these four requirements helps states and communities develop a
broad perspective of chemical hazards for the entire community, as well as for individual

facilities. Regulations implementing EPCRA are codified in Title 40 of the Code of Federal
Regulations, parts 350 to 372. The chemicals covered by each of the sections are different, as
are the quantities that trigger reporting. Table 1 summarizes the chemicals and thresholds.
What Are Emergency Response Plans (Sections 301-303)?
Emergency Response plans contain information that community officials can use at the time of
a chemical accident. Community emergency response plans for chemical accidents were
developed under section 303. LEPCs are required to update these plans annually. The plans
must:
•	Identify facilities and transportation routes of extremely hazardous substances;
•	Describe emergency response procedures, on and off site;
•	Designate a community coordinator and facility coordinator(s) to implement the plan;
•	Outline emergency notification procedures;
•	Describe how to determine the probable affected area and population by releases;
•	Describe local emergency equipment and facilities and the persons responsible for them;
•	Outline evacuation plans;
•	Provide a training program for emergency responders (including schedules); and,
•	Provide methods and schedules for exercising emergency response plans.
Planning activities of LEPCs and facilities initially focused on, but were not limited to, the 406
extremely hazardous substances (EHSs) listed by EPA in 1987 (now currently 355 chemicals).
The list includes the threshold planning quantities (minimum limits) for each substance. Any
facility that has EHS at or above its threshold planning quantity must notify the State
Emergency Response Commission (SERC) or the Tribal Emergency Response Commission
(TERC) and Local Emergency Planning Committee (LEPC) within 60 days after they first
receive a shipment or produce the substance on site.
What Are the Emergency Notification Requirements (Section 304)?
Facilities must immediately notify the LEPC and the SERC or the TERC if there is a release
into the environment of a hazardous substance that is equal to or exceeds the minimum
reportable quantity set in the regulations. This requirement covers the 355 extremely
hazardous substances, as well as the more than 700 hazardous substances subject to the
emergency notification requirements under CERCLA section 103(a)(40 CFR 302.4). Some
chemicals are common to both lists. Initial notification can be made by telephone, radio, or in
person. Emergency notification requirements involving transportation incidents can be met by
dialing 911, or in the absence of a 911 emergency number, calling the operator. This
emergency notification needs to include:
•	The chemical name;
•	An indication of whether it is an extremely hazardous substance;
•	An estimate of the quantity released into the environment;
•	The time and duration of the release;
•	Whether the release occurred into air, water, and/or land;
•	Any known or anticipated acute or chronic health risks associated with the
emergency, and where necessary, advice regarding medical attention for
exposed individuals;
•	Proper precautions, such as evacuation or sheltering in place; and,
•	Name and telephone number of contact person.

A written follow-up notice must be submitted to the SERC or the TERC and LEPC as soon as
practicable after the release. The follow-up notice must update information included in the initial
notice and provide information on actual response actions taken and advice regarding medical
attention necessary for citizens exposed.
What Are the Community Right-to-know Requirements (Sections 311 and 312)?
Under Occupational Safety and Health Administration (OSHA) regulations, employers must
maintain a material safety data sheet (MSDS) for any hazardous chemicals stored or used in
the work place. Approximately 500,000 products are required to have MSDSs.
Section 311 requires facilities that have MSDSs for chemicals held above certain threshold
quantities to submit either copies of their MSDSs or a list of these chemicals to the SERC or
TERC, LEPC, and local fire department. If the facility owner or operator chooses to submit a list
of chemicals, the list must include the chemical or common name of each substance and must
identify the applicable hazard categories. These hazard categories are:
Health Hazards
Carcinogenicity
Acute toxicity (any route of exposure)
Reproductive toxicity	
Skin Corrosion or Irritation
Respiratory or Skin Sensitization	
Serious eye damage or eye irritation
Specific target organ toxicity (single or
repeated exposure)
Germ cell mutagenicity	
Aspiration Hazard
Hazard Not Otherwise Classified (HNOC)
If a list is submitted, the facility must submit a copy of the MSDSs for any chemical on the list
upon request by the LEPC.
Facilities that start using a hazardous chemical or increase the quantity to exceed the
thresholds must submit MSDSs or a list of MSDSs chemicals within three months after they
become covered. Facilities must provide a revised MSDS to update the original MSDS or
list if significant new information is discovered about the hazardous chemical.
Facilities covered by section 311 must submit annually an Emergency and Hazardous
Chemical Inventory Form to the LEPC, the SERC or the TERC, and the local fire department
as required under section 312. Facilities provide either a Tier I or Tier II inventory form. Tier
I inventory form include the following aggregate information for each applicable hazard
category:
•	An estimate (in ranges) of the maximum amount of hazardous chemicals for each
category present at the facility at any time during the preceding calendar year;
•	An estimate (in ranges) of the average daily amount of hazardous
chemicals in each category; and,

•	The general location of hazardous chemicals in each category. The Tier II
inventory form contains basically the same information as the Tier I, but it must
list the specific chemicals. Tier II inventory form provide the following information
for each chemical:
•	The chemical name or the common name as indicated on the MSDS;
•	An estimate (in ranges) of the maximum amount of the chemical present at any
time during the preceding calendar year and the average daily amount;
•	A brief description of the manner of storage of the chemical;
•	The location of the chemical at the facility; and
•	An indication of whether the owner elects to withhold location information from
disclosure to the public.
Many states now require Tier II inventory form or the state equivalent including electronic
reporting under state law. Section 312 information must be submitted on or before March 1
each year for information on chemicals present at the facility in the previous year. The
information submitted under sections 311 and 312 is available to the public from LEPCs and
SERCs or TERCs.
What is the Toxics Release Inventory (Section 313)?
Section 313 of EPCRA established the Toxics Release Inventory. TRI tracks the management
of certain toxic chemicals that pose a threat to human health and the environment. Facilities in
different industry sectors must annually report how much of each chemical they managed
through recycling, energy recovery, treatment and environmental releases. TRI reporting forms
must be submitted to EPA and the appropriate state or tribe by July 1 of each year. These
forms cover environmental releases and other management of toxic chemicals that occurred
during the previous calendar year.
The information submitted by facilities is compiled in the Toxics Release Inventory and
made available to the public through the TRI website: https://www.epa.gov/toxics-release-
inventorv-tri-proqram. TRI helps support informed decision-making by industry,
government, non-governmental organizations and the public. TRI includes information
about:
•	On-site releases (including disposal) of toxic chemicals to air, surface water
and land;
•	On-site recycling, treatment and energy recovery associated with TRI
chemicals;
•	Off-site transfers of toxic chemicals from TRI facilities to other locations;
•	Pollution prevention activities at facilities;
•	Releases of lead, mercury, dioxin and other persistent, bioaccumulative and
toxic (PBT) chemicals; and
•	Facilities in a variety of industry sectors (including manufacturing, metal
mining and electric power generation) and some federal facilities.
A complete list of covered facility sectors is available online: https://www.epa.gov/toxics-release-
inventorv-tri-proqram/mv-facilitvs-six-diqit-code-tri-coverd-industrv
Some of the ways TRI data can be used include:
•	Identifying sources of toxic chemical releases;
•	Beginning to analyze potential toxic chemical hazards to human health and
the environment; and
•	Encouraging pollution prevention at facilities.

What Else Does EPCRA Require?
Trade Secrets. EPCRA section 322 allows facilities to file trade secrets in their reports under
EPCRA sections 303, 311, 312, and 313. Only the specific chemical identity may be claimed as
a trade secret, though a generic class for the chemical must be provided. The criteria a facility
must meet to claim a chemical identity as a trade secret are in 40 CFR part 350. A facility cannot
claim trade secrets under EPCRA section 304.
Even if specific chemical identity information can be legally withheld from the public, EPCRA
section 323 allows the information to be disclosed to health professionals who need the
information for diagnostic and treatment purposes or local health officials who need the information
for prevention and treatment. In non-emergency cases, the health professional must sign a
confidentiality agreement with the facility and provide a written statement of need. During a
medical emergency, the health professional may obtain the specific chemical identity from the
facility for treatment.
Any person may challenge trade secret claims by petitioning EPA. The Agency must then review
the claim and rule on its validity.

EPCRA Penalties. EPCRA section 325 allows for civil and administrative penalties ranging
from up to $21,916 - $164,3671 per violation per day when facilities fail to comply with the
reporting requirements. Criminal penalties up to $50,000 or five years in prison apply to any
person who knowingly and willfully fails to provide emergency release notification. Penalties of
not more than $20,000 and/or up to one year in prison apply to any person who knowingly and
willfully discloses any information entitled to protection as a trade secret.
Citizens Suits. EPCRA section 326 allows citizens to initiate civil actions against EPA,
SERCs, and the owner or operator of a facility for failure to meet the EPCRA requirements. A
SERC or TERC, LEPC, and state or local government may institute actions against facility
owner or operator for failure to comply with EPCRA requirements. In addition, states may sue
EPA for failure to provide trade secret information.

Are There Other Laws That Provide Similar Information?
The Oil Pollution Act (OPA) of 1990 includes national planning and preparedness provisions for
oil spills that are similar to EPCRA provisions for extremely hazardous substances. Plans are
developed at the local, state and federal levels. The OPA plans offer an opportunity for LEPCs
to coordinate their plans with area and facility oil spill plans covering the same geographical
area.
The 1990 Clean Air Act Amendments require the EPA and OSHA to issue regulations for
chemical accident prevention. Facilities that have certain chemicals above specified threshold
quantities are required to develop a risk management program to identify and evaluate hazards
and manage those hazards safely. Facilities subject to EPA's Chemical Accident Prevention
regulations must submit a risk management plan (RMP) summarizing its program.
