ERNS - The Emergency Response Notification System
First Line of Defense
When a release or spill occurs, the company responsible for the release, its response contractors, the local fire and police departments, and the local emergency response personnel provide the first line of defense. If needed, a variety of state agencies stand ready to support, assist, or take over response operations if an incident is beyond local capabilities. In cases where a local government or Indian tribe conducts temporary emergency measures in response to a hazardous substance release, but does not have emergency response funds budgeted, EPA operates the
Local Governments Reimbursement program
that will reimburse local governments or Indian tribes up to $25,000 per incident.
This flowchart summarizes the steps.
If the amount of a hazardous substance release or oil spill exceeds the established
, the organization responsible for the release or spill is required by law to notify the federal government's
National Response Center (NRC)
. Once a report is made, the NRC immediately notifies a pre-designated EPA or U.S. Coast Guard
On-Scene Coordinator (OSC)
, based on the location of the spill. The procedure for determining the lead agency is clearly defined so there is no confusion about who is in charge during a response. The OSC determines the status of the local response and monitors the situation to determine whether, or how much, federal involvement is necessary. It is the OSC's job to ensure that the cleanup, whether accomplished by industry, local, state, or federal officials, is appropriate, timely, and minimizes human and environmental damage.
The OSC may determine that the local action is sufficient and that no additional federal action is required. If the incident is large or complex, the federal OSC may remain on the scene to monitor the response and advise on the deployment of personnel and equipment. However, the federal OSC will take command of the response in the following situations:
- If the party responsible for the chemical release or oil spill is unknown or not cooperative;
- If the OSC determines that the spill or release is beyond the capacity of the company, local, or state responders to manage; or
- For oil spills, if the incident is determined to present a substantial threat to public health or welfare due to the size or character of the spill.
The OSC may request additional support to respond to a release or spill, such as additional contractors, technical support from EPA's
Environmental Response Team
, or Scientific Support Coordinators from EPA or the
National Oceanic and Atmospheric Administration
. The OSC also may seek support from the
Regional Response Team
to access special expertise or to provide additional logistical support. In addition, the
National Response Team
stands ready to provide backup policy and logistical support to the OSC and the RRT during an incident.
The federal government will remain involved at the oil spill site following response actions to undertake a number of activities, including assessing damages, supporting restoration efforts, recovering response costs from the parties responsible for the spill, and, if necessary, enforcing the liability and penalty provisions of the
Clean Water Act
, as amended by the
Oil Pollution Act of 1990
- Section 110.1
Defines oil, discharge, navigable waters, and other terms relevant to oil releases.
- Section 110.2
Establishes the types of discharges that are subject to this regulation.
- Section 110.3
Establishes the criteria that determine when an oil discharge into navigable waters is harmful to the public health or welfare.
- Section 110.4
Establishes the criteria that determine when an oil discharge into the contiguous zone of the U.S. is harmful to the public health or welfare.
- Section 110.5
Establishes the criteria that determine when an oil discharge into waters beyond the contiguous zone of the U.S. is harmful to the public health or welfare.
- Section 110.6
Prohibits any person from discharging oil into U.S. waters in an amount that is harmful to the public health or welfare.
- Section 110.7
Exempts from this rule those discharges from properly functioning vessel engines.
- Section 110.8
Prohibits the addition of dispersants or emulsifiers to oil which is going to be discharged, if it results in a violation of Part 110.
- Section 110.9
Authorizes the Administrator of the EPA to allow oil to be discharged for research or demonstration projects related to oil spill prevention or control.
- Section 110.10
Requires the person in charge of a facility or vessel to report any harmful discharge of oil to the Federal government's National Response Center or other available authority.
- Section 110.11
Defines the term "discharge" and notes exceptions for vessel engines and discharges permitted under MARPOL.
Learn about ERNS, the Emergency Response Notification System, from these informative fact sheets:
- An Overview of ERNS
-- This fact sheet contains general ERNS information, such as: reporting requirements for reports contained in ERNS, how spill notifications in ERNS are collected, the number of release reports for three general material types, uses for and limitations of ERNS data, the different data output formats, and a map of EPA Regions and their FOIA offices.
- ERNS Statistics
-- This fact sheet gives examples of one use of ERNS data - statistical analyses of large data sets. The information is presented in tables, pie charts, and a map, and identifies the annual number of CERCLA and petroleum notifications in ERNS for various size categories between 1987 and 1994; the different environmental media affected by reported CERCLA and petroleum spills; and the number of reported spills per state between 1987 and 1994.
- ERNS and CERCLA
-- This fact sheet focuses on reports in ERNS of releases of CERCLA hazardous substances. ERNS and CERCLA discusses: reported causes of CERCLA hazardous substance spills in ERNS, the definition of a CERCLA hazardous substance, the five most frequently reported CERCLA hazardous substances in ERNS from 1987-1993, CERCLA reporting requirements, and what happens to a spill notification after it is received by the NRC.
- ERNS and Oil
-- This fact sheet concentrates on notifications of releases of petroleum and non-petroleum oils in ERNS. Specific information includes: annual number of reports of releases of petroleum and non-petroleum oils between 1987 and 1996; examples of petroleum, non-petroleum, and animal and vegetable oils; reported sources of petroleum and non-petroleum oil spills; and reporting requirements for oil spills.
- ERNS and Site Searches
-- This fact sheet contains information on conducting searches of the ERNS database for a specific location (e.g., street address, county, state), such as: a background on site searches, how to request a site search, how much an ERNS search will cost, and the available formats of the report generated if the search yields any results.
- ERNS and OPA 90
-- This fact sheet investigates the effect that the Oil Pollution Act of 1990 (OPA 90) may have had on the number and size of release notifications in ERNS. The fact sheet discusses: the background of OPA 90, the average number of annual reports of oil spills in ERNS between 1989 and 1995, sources of oil spills to inland and coastal waters, and the average size of reported oil spills in ERNS between 1989 and 1995.
