ATTACHMENT 2: CONTRACTOR REQUIREMENTS DOCUMENT	1



SECTION 1.  SCOPE.  

This Manual and DOE Order 231.1A, Environment, Safety, and Health Reporting, dated 
08-19-03, set forth the minimum set of occurrence reporting requirements for Department of 
Energy (DOE) Departmental Elements, including the National Nuclear Security 
Administration (NNSA), and contractors responsible for the management and operation of 
DOE-owned and DOE-leased facilities, including NNSA facilities.  These requirements 
include categorizing occurrences related to safety, environment, health, or operations 
("Reportable Occurrences"); notifying DOE of these occurrences; and developing and 
submitting documented follow-up reports.  These occurrence reporting directives further 
require that the notifications be timely in accordance with the significance of the occurrence, 
and that the written reports contain appropriate information describing the occurrence, 
significance, causal factors, and corrective actions.  No exemption to this minimum set of 
occurrence reporting requirements is permitted.

SECTION 2.  PURPOSE.  

This Manual provides detailed information for reporting occurrences and managing 
associated activities at DOE facilities, including NNSA facilities.  It complements DOE O 
231.1A, Environment, Safety, and Health Reporting and its use is required by that Order.  
Information gathered in response to the requirements in this Order and Manual is used for 
analysis of the Department's performance in environmental protection and the safety and 
health of its workers and the public.  This information is also used to develop lessons learned 
and document events that impact DOE operations.

SECTION 3.  APPLICABILITY.

a.	DOE Elements.  Except for the exclusions in paragraph c of this section, this Manual 
applies to all DOE Elements, including NNSA, as listed in Attachment 1. 

Where a responsibility or authority is assigned to an organization that is restructured, 
the responsibility or authority will be reassigned to the appropriate successor 
organization as explicitly determined by the appropriate Lead Program Secretarial 
Officer.

b.	Site/Facility Management Contractors.					

	(1)	The Contractor Requirements Document (CRD), Attachment 2, sets forth 
requirements of this Manual that will apply to site/facility management 
contractors whose contracts include the CRD.

(2)	Except for the exclusions in paragraph c of this section, this CRD must be 
included in all site/facility management contracts. 

(3)	This Manual does not apply to other than site/facility management contractors.  
Any application of any requirements of this Manual to other than site/facility 
management contractors will be communicated separately from this Manual. 

(4)	The office identified in the Responsibilities section is responsible for telling 
contracting officers which site/facility management contractors are affected.  
Once notified, contracting officers are responsible for incorporating the CRD into 
the contracts of affected site/facility management contractors via the laws, 
regulations, and DOE directives clause of the contracts.

(5)	As the laws, regulations, and DOE directives clause of site/facility management 
contracts state, regardless of the performer of the work, the site/facility 
management contractor with the CRD incorporated into its contract is responsible 
for compliance with the requirements of the CRD.  An affected site/facility 
management contractor is responsible for flowing down the requirements of this 
CRD to subcontracts at any tier to the extent necessary to ensure the site/facility 
management contractor's compliance with the requirements.  In doing so, the 
contractor must not unnecessarily or imprudently flow down requirements to 
subcontracts.  That is, the contractor will both ensure that it and its subcontractors 
comply with the requirements of this CRD and only incur costs that would be 
incurred by a prudent person in the conduct of competitive business.  

c.	Exclusions.  

 (1)	Power Marketing Administration reporting of major electrical power outages, 
disturbances, and fuel shortages subject to the emergency power system 
reporting requirements prescribed in 10 CFR 205, and 350-354, Report Of 
Major Electric Utility Systems Emergencies.

(2)	Activities under the authority of the Director, Naval Nuclear Propulsion, 
pursuant to Executive Order 12344, as set forth in Public Laws 98-525 and 
106-65.

SECTION 5.  OCCURRENCE REPORTING. 
 
To implement the occurrence categorization, notification, reporting, and processing system, 
the key responsible personnel must be identified and procedures developed, approved, and 
implemented to ensure that all of the occurrence reporting requirements, as delineated in 
DOE O 231.1A and this Manual, are met.  The Facility Manager must be available at all 
times to carry out the responsibilities for the categorization, notification, and reporting 
requirements.  Facility operators are required to ensure that occurrences resulting from 
activities performed by subcontractors in support of facility operation are reported in 
accordance with the provisions of this Manual.

For reportable occurrences, facility personnel are required to categorize the occurrences, 
notify DOE as required, and prepare and submit Occurrence Reports.  This Section addresses 
the process for meeting these requirements, including roles and actions for key facility 
personnel and the steps to be taken to ensure performance.  In Section 11, the Occurrence 
Reporting Model summarizes the various time limits, levels of investigation and analysis, 
corrective action development and tracking, approvals, and lessons learned development by 
Significance Category.

The documentation and distribution requirements will be satisfied by utilization of a 
centralized unclassified DOE operational database, the computerized Occurrence Reporting 
and Processing System (ORPS).  However, under no circumstances will Occurrence Reports 
containing classified information or Unclassified Controlled Nuclear Information (UCNI) be 
entered into the ORPS database.  Requirements regarding security classification are provided 
in Section 7.  

Occurrences involving foreign personnel, governments, organizations, entities or influence 
must be reported by the Facility Manager to the Office of Counterintelligence or the Office 
of Defense Nuclear Counterintelligence, as appropriate. Such reporting is not intended to 
interfere with or delay any actions directed toward protection of personnel or property.

5.1	Event or Condition Identification.

a.	Occurrences may be identified by direct observation of equipment or process 
malfunctions, log or record reviews, operator recognition of their own or others' 
errors, or other means.  

b.	Operations personnel must take appropriate immediate action to stabilize and/or 
place the facility/operation in a safe condition and ensure that any potential 
environmental effects are stabilized and workers are treated for injuries 
sustained.  Also, actions should be taken to preserve conditions for continued 
investigation; however, these actions are not to interfere with establishing a safe 
condition.

c.	The facility staff and operators must, upon identification of an abnormal or 
suspected abnormal event or condition, promptly notify the appropriate line 
management and the Facility Manager of the event status and record and/or 
archive all pertinent information, including details concerning the discovery of 
the occurrence and actions taken to stabilize or place the facility/operation in a 
safe condition.

5.2	Event or Condition Categorization.  The Facility Manager must categorize all 
occurrences, except Operational Emergencies, within 2 hours of discovery by the 
cognizant facility staff following the site/facility-specific procedures developed in 
accordance with Section 9 of this Manual.  The significance categories, as outlined in 
the Occurrence Reporting Model (Section 11), are for those occurrences of interest 
for complex-wide occurrence reporting and are described very generally below.  
More definitively, Section 6, Reporting Criteria, provides very specific reporting 
criteria and assigns the appropriate significance category to each criterion.  Local 
implementing procedures may increase the reporting requirements but may not 
decrease the requirements below.

a.	Operational Emergencies (OE).  Operational Emergencies are defined in DOE O 
151.1A, Comprehensive Emergency Management System.  Operational 
Emergency Occurrences are the most serious occurrences and require an 
increased alert status for onsite personnel and, in specified cases, for offsite 
authorities.  The prompt notification requirements, definitions, criteria, and 
classifications of operational emergencies and appropriate responses are provided 
in DOE O 151.1A.  Written Occurrence Reports must be completed in accordance 
with this Manual.  

b.	Significance Category 1.  Occurrences in this category are those that are not 
Operational Emergencies and that have a significant impact on safe facility 
operations, worker or public safety and health, regulatory compliance, or 
public/business interests.

c.	Significance Category R.  Occurrences in this category are those identified as 
recurring, as determined from the periodic performance analysis of occurrences 
across a site.

d.	Significance Category 2.  Occurrences in this category are those that are not 
Operational Emergencies and that have a moderate impact on safe facility 
operations, worker or public safety and health, regulatory compliance, or 
public/business interests.

e.	Significance Category 3.  Occurrences in this category are those that are not 
Operational Emergencies and that have a minor impact on safe facility operations, 
worker or public safety and health, regulatory compliance, or public/business 
interests

f.	Significance Category 4.  Occurrences in this category are those that are not 
Operational Emergencies and that have some impact on safe facility operations, 
worker or public safety and health, public/business interests.
 
If the consequences are not fully determined or the event exceeds the threshold of 
more than one criterion (see Section 6), then the event must be categorized at the 
higher criteria level being considered.  The occurrence criterion must be continuously 
reevaluated and changed, as needed, when new information becomes available.
 
5.3	DOE HQ Operations Center Prompt Notifications.

5.3.1	Operational Emergencies.  The requirements for the prompt and follow-up 
notifications to DOE (including NNSA) and other agencies and the appropriate 
emergency responses to be taken are provided in DOE O 151.1A, 
Comprehensive Emergency Management System.  The specific procedures on 
how these events are categorized and how and when DOE is notified are 
included in the site/facility-specific emergency response plans or procedures.  If 
an event has been declared an Operational Emergency, the Facility Manager 
will be responsible for the written Notification Report and for the completion of 
all other occurrence reporting requirements, as described below.

5.3.2	Prompt Notifications for Significance Category 1, 2, 3, and 4 Reportable 
Occurrences.  

a.	The Facility Manager must notify the DOE Facility Representative (in a 
manner determined locally) and the DOE Headquarters Operations Center 
(DOE HQ OC), as required, of the following reportable occurrences as 
soon as practical (i.e., promptly), but no later than 2 hours after 
categorization:

1)	All Significance Category 1 occurrences require a Prompt Notification 
to the Facility Representative and DOE HQ OC.

2)	All Significance Category 2 occurrences require a Prompt Notification 
to the Facility Representative and, if directed by the Facility 
Representative, to the DOE HQ OC.

3)	All Significance Category 3 occurrences require a prompt notification 
to the Facility Representative.

4)	Additionally, specific Significance Category 2, 3, and 4 occurrences 
(identified as requiring prompt notification with an asterisk in the 
reporting criteria listed in Section 6) require prompt notification to the 
Facility Representative and DOE HQ OC.

b.	The DOE HQ OC will relay notifications to the appropriate HQ-level 
Program Manager and make any further notifications, as required.  

c.	The Facility Manager may use the local Field/Site Emergency Operations 
Center to expedite establishing the communication link required and to 
record and archive conversations.  The prompt notification process is as 
follows:

1)	The Facility Manager must e-mail the prompt notification of the 
reportable occurrence to the DOE HQ OC, and follow up with a phone 
call to the DOE HQ OC to ensure receipt of the e-mail.  

2)	The Prompt Notification must clearly state/select the Significance 
Category (1, R, 2, 3, or 4) and identify the specific reporting criteria 
associated with the occurrence. 

3)	Prompt Notification to the DOE HQ OC must include information on 
the following items:

a)	Occurrence Significance Category 
b)	Location and description of the event 
c)	Date and time of discovery 
d)	Damage and casualties 
e)	Impact of event on other activities and operations 
f)	Protective actions taken or recommended 
g)	Weather conditions at the scene 
h)	Level of media interest at scene/facility/site.
i)	Other notifications made

4)	All information should be clear and succinct.  Avoid jargon.  
Uncommon or site/facility-specific abbreviations and acronyms should 
be fully described.

5)	The Facility Manager must follow the appropriate security procedures 
if the notification to DOE may contain classified or sensitive 
information.

6)	If the occurrence is recategorized, then the occurrence must be 
reconsidered for prompt notification.  If appropriate, the Facility 
Manager must notify the Facility Representative and the DOE HQ OC 
as soon as practical, but within the prompt notification time 
requirements of the new Significance Category for the recategorized 
occurrence and provide the Occurrence Report number.  The DOE HQ 
OC will make any required internal DOE HQ notifications.

7)	Follow-up notifications must be made to DOE for any further 
degradation in the level of safety or impact on the environment, health, 
or operations of the facility or other worsening conditions subsequent 
to the previous notification.  If a degradation results in upgrading the 
event to an Operational Emergency, the DOE HQ OC must be notified 
in accordance with DOE O 151.1A, Comprehensive Emergency 
Management System.

5.4	Written Notification Report. The Facility Manager must prepare the written 
Notification Report (including all required fields and all other fields for which 
information is known) as discussed in DOE G 231.1-1, Occurrence Reporting and 
Performance Analysis Guide, and distribute it per Section 5.6.e.  Direct entry into the 
computerized Occurrence Reporting and Processing System (ORPS) satisfies this 
requirement.  Any changes in the reporting criteria of the occurrence, which result in 
a change, either lower or higher, to the Significance Category, must be documented in 
an Update Report and submitted within the timeframe required for the Notification 
Report under the new Significance Category.  A discussion on the change in 
categorization must be included in the Description of Occurrence field in the Update 
Report.

5.4.1	Occurrence Report Preparation.  In preparing the Notification Report, and 
subsequently the Final Report, the following writing instructions must be 
followed:

a.	The report should enable the general reader to understand the basic "what, 
who, when, where, how" of the event, the safety issues involved, and the 
actions taken.

b.	The Subject/Title and the first paragraph of the Occurrence Description 
should relay the essential nature of the event (i.e., a summary of the 
occurrence in newspaper style).

c.	All information should be clear and succinct.  Avoid redundant and 
unnecessary text, and lengthy "log book" accounts, unless a discussion of 
the event in chronological order is considered essential to understanding 
the event.

d.	Complex and more significant occurrences should warrant a greater level 
of detail.  Significance Category 4 occurrences would likely need only a 
short paragraph under Occurrence Description.  However, all reports 
should present enough information so that the general reader understands 
why the event needs to be reported and what the effect is.

e.	Avoid jargon and uncommon or site/facility-specific abbreviations and 
acronyms.  If used, acronyms should be initially spelled out. 

f.	Unless necessary to record and explain the event (e.g., suspect/counterfeit 
items or material), use general descriptions of equipment, procedures, etc., 
rather than presenting lengthy detailed titles and the numbers and letters 
assigned to those items.  

g.	Quantify the level of contamination, dose, release, and damage (e.g., 
estimate the acres of wild land burned) when possible, instead of merely 
stating a reportable limit was exceeded.    

h.	Use active rather than passive voice whenever possible.  For example, 
write, "the electrician severed the conduit" rather than "the conduit was 
severed."

i.	When appropriate for clarification, photos, sketches, and drawings must be 
maintained with the occurrence report record.  In addition, sites are 
encouraged but not required to make photos, sketches, and drawings 
available via a Web page, with the Web page address included as a 
hyperlink in the ORPS report.

5.4.2	Notification Report Submittal Schedule.  The written Notification Report must 
be submitted according to the following schedule:
 
a.	Reports for Operational Emergencies and Significance Category 1 
Occurrences.  Before the close of the next business day from the time of 
categorization (not to exceed 80 hours).  

b.	Reports for Significance Categories R and 2 Occurrences.  Before the 
close of the next business day from the time of categorization.  

c.	Reports for Significance Category 3 Occurrences.  No later than close of 
business on the second business day from the time of categorization.

d.	Reports for Significance Category 4 Occurrences.  Only a Short Form 
Report is required by close of business the second business day from the 
time of categorization. 

5.5	Occurrence Investigation and Analysis.  The following steps describe an acceptable 
process for submitting Update Reports and conducting the investigation and analysis 
of a specific occurrence.  DOE 5480.19, Conduct Of Operations Requirements For 
DOE Facilities, and DOE-STD-1045-93, Guide to Good Practices for Notifications 
and Investigation of Abnormal Events, should be considered when establishing a 
program for investigation of occurrences.  In cases of conflict between DOE 5480.19 
or DOE-STD-1045-93 and this Manual, the requirements of this Manual must be 
followed.

In general, the investigative process is used to gain an understanding of the 
occurrence, its causes, and the corrective actions necessary to prevent recurrence or 
only remedy the problem, based on the significance of the occurrence.  If DOE is 
doing a Type A or B investigation, the Facility Manager is not required to perform an 
identical investigation.  However, the Facility Manager is still required to do the 
preliminary assembly of information to turn over to the DOE Accident Investigation 
Board, in accordance with DOE O 225.1A, Accident Investigation.  

a.	The Facility Manager should use the graded approach described in the 
Occurrence Reporting Model (Section 11) when determining the level of effort 
required for the investigation into the causes of the occurrence.  The graded 
approach is based on the significance, severity, or risk associated with the event 
or condition.

For Operational Emergencies, in general, the investigation, problem analysis, 
and corrective action process should parallel the process for Significance 
Category 1 occurrences. However, the Facility Manager should consider a 
graded approach when determining the level of effort for the investigation into 
the cause of the Operational Emergency. The graded approach is based on 
whether the Operational Emergency was directly caused by DOE operations or 
resulted from non-DOE operations or natural phenomena.  For example, 
investigations of an Operational Emergency involving the release of hazardous 
materials might require an accident investigation or the assembly of a team of 
investigators and subject matter experts.  Investigation of an Operational 
Emergency resulting from a DOE facility being required to implement 
protective actions because a non-DOE activity offsite released hazardous 
materials or an Operational Emergency resulting from an earthquake may not 
require root cause determination because the initiating event was clearly beyond 
DOE's control.  

b.	All causes must be identified as required in the Occurrence Reporting Model 
(Section 11) and included in the occurrence report.  The cause codes to be used 
for reporting are provided in the Causal Analysis Tree (Section 11).  Guidance 
on selecting the appropriate cause code is provided in DOE G 231.1-2, 
Occurrence Reporting Causal Analysis Guide.  The Cause Description field 
should include a brief discussion to clearly link the event to the cause code(s).  
For those occurrences that require a formal root cause analysis, any of the site 
approved root cause analysis methodologies are permitted.  The methodology 
used must be included in the Cause Description field of the occurrence report.  
In addition to determining the causes of the occurrence, any weaknesses in the 
facility's implementation of the ISM program must be identified and entered in 
the ISM field, as discussed in DOE G 231.1-1, Occurrence Reporting and 
Performance Analysis Guide.

c.	In addition to submitting an Update Report when the Significance Category of 
the occurrence has been changed (as stated in Section 5.4), the Facility Manager 
must submit and distribute an Update Report for all occurrences, with the 
exception of Significance Category 4 occurrences, if there is any significant and 
new information about the occurrence.  The status of the investigation, recurring 
consequences, and the identification of additional component defects are 
activities associated with the occurrence and must be included in Update 
Reports. 

d.	Using a graded approach as described in the Occurrence Reporting Model (see 
Section 11), the Facility Manager should consult in a timely manner with the 
Facility Representative and the Program Manager, as appropriate, for their 
assessment, if any, of the occurrence.  

5.6	Occurrence Report Closure.  The following steps describe an acceptable process for 
closing out the Final Report for all occurrences except those categorized as 
Significance Category 4:

a.	The Final Report must be prepared by the Facility Manager and submitted as 
soon as practical but within 45 calendar days after initial categorization of the 
occurrence. The Final Report must be prepared using the writing instructions 
listed in Section 5.4.1 and must document the following:

(1)	The significance, nature, and extent of the event or condition;

(2)	The causes of the event or condition (including the root cause, as required) 
using the codes provided in the Causal Analysis Tree (Section 11);  

(3)	The immediate actions taken and the corrective action(s) to be taken (see 
Section 5.6.f), as required by the Occurrence Reporting Model (Section 
11); and

(4)	The lessons learned.

b.	If the required analysis cannot be completed within 45 calendar days after initial 
categorization, an Update Report must be submitted within the 45 days.  The 
Update Report must provide a detailed explanation of the delay and provide an 
estimated date for submittal of the Final Report.  This information must be 
reported in the "Evaluation" block of the Occurrence Report.  It is expected that 
the analysis of most occurrences will be completed and the Final Report 
submitted within the 45 calendar days.  However, for certain occurrences, such 
as those requiring an accident investigation, it is understood that the information 
required for the Final Report may not be available within this time.  For 
occurrences resulting in an accident investigation, all causes (direct, 
contributing, and root) identified in the accident investigation report, as well as 
the corrective actions developed in response to the judgments of need, must be 
included in the Final Report. 

c.	For Operational Emergencies and Significance Category 1, R, and 2 Final 
Reports, the Facility Representative must review, approve, and add any 
comments, as necessary, within 14 calendar days after receipt of the report.  For 
Operational Emergencies and Significance Category 1 Final Reports, after the 
Facility Representative has approved the occurrence report, the Program 
Manager must review, approve, and add any comments to the Final Report 
within 14 calendar days.  If the ORPS database is being used, the Facility 
Representative and Program Manager's comments should be provided through 
ORPS.  Facility Representative and Program Manager comments are not 
required for their approval of the report.

d.	If the Final Report is not approved by the Facility Representative or the 
Program Manager, the Facility Representative or Program Manager who is 
rejecting the report must provide the reason for disapproval in the comment 
section of the report at the time the action is taken.  The revised Final Report 
must be resubmitted within 21 calendar days of the disapproval.  If it cannot be 
resubmitted within this time, an Update Report must be submitted within the 21 
calendar days explaining the delay and providing an estimated date for 
resubmittal of the Final Report.  This information must be reported in the 
"Evaluation" block of the Occurrence Report.

e.	All Occurrence Reports must be distributed as soon as practical to the 
following:

	-	Facility Representative
			-	Program Manager 
			-	Heads of all Field organizations (including NNSA)
			-	Office of Environment, Safety and Health (Office of Performance 
Assessment and Analysis) and Administrator (NNSA) and
	-	DOE Management and Operations or Integrating contractors

If the Occurrence Reports are entered into the ORPS database, the distribution 
requirement is automatically satisfied.  

f.	As prescribed on the Occurrence Reporting Model (Section 11) and depending 
on the Significance Category, the Facility Manager must track all corrective 
actions to closure, including independent verification or sampling at the facility 
level and also evaluate the effectiveness of the corrective actions to prevent 
recurrence (if applicable). Site/contractor corrective action programs must 
include management of Significance Category 4 occurrences, whose corrective 
actions are not managed through ORPS.  

g.	The cognizant Facility Manager may use the ORPS database to track the status 
of Final Report corrective actions.  For those facilities that do not choose to use 
ORPS to track the status of their corrective actions, the specific corrective 
action tracking number from the local corrective action tracking system must be 
entered into ORPS.  Any changes made to the corrective actions tracked in the 
local corrective action system must follow the site's approved change process 
and should be updated in ORPS.  For Significance Category 2 and higher 
reports, any text change to a corrective action previously entered in ORPS must 
be updated in ORPS with Facility Representative approval.  A status report of 
all incomplete Occurrence Reports (not Final) and incomplete corrective actions 
(for those sites who choose to track the status of their corrective actions using 
ORPS) will be available at any time from the ORPS database.  Retain all 
supporting information pertaining to each occurrence or report (e.g., graphs, 
analyses, and formal investigation reports) in accordance with Departmental 
Records Disposition Schedules, as required by 36 CFR Chapter 12, Subchapter 
B, RECORDS MANAGEMENT.

5.7	Short Form Reports.  A Short Form Report, as described in DOE G 231.1-1, 
Occurrence Reporting and Performance Analysis Guide, must be prepared and 
submitted for all Significance Category 4 occurrences no later than 2 business days 
after categorization of the occurrence.  This report will satisfy all of the written 
reporting requirements for these occurrences.

5.8	Performance Analysis and Identification of Recurring Occurrences.  Each contractor 
at a site and managers at DOE owned and operated sites must perform ongoing, but as 
a minimum quarterly, analyses of events during a 12-month period to look for trends.  
This periodic performance analysis must evaluate occurrences of all significance 
categories plus contractor-/operator-determined non-reportable events in order to 
prevent serious events from occurring.  Quarterly performance analysis results must 
be reported to contractor and DOE line management in order to achieve 
improvements.

Occurrences identified as recurring require a new occurrence report to be submitted 
for notification of the recurring issue, with investigation, root cause analysis, and 
corrective actions subsequently required.  Previous individual Occurrence Report 
Numbers associated with the recurring issue must be provided in the Similar 
Occurrence Report Numbers field.  The reporting organization should select the 
appropriate reporting criteria associated with the recurring issue.  If no specific 
reporting criteria can be identified, the Reporting Criteria should be listed as Group 
10, Criteria #2. 

Recurring occurrences must be categorized and reported collectively as a Significance 
Category R occurrence, even if each individual occurrence had been originally 
categorized at a higher or lower significance level (e.g., as Significance Category 1 or 
4 or even as non-reportable occurrences).  See the Occurrence Reporting Model 
(Section 11) to learn the requirements for a Significance Category "R" occurrence.  
More information on the performance analysis process for all occurrence reports and 
specifics on recurring occurrences are provided in DOE G 231.1-1, Occurrence 
Reporting and Performance Analysis Guide.

DOE Headquarters' Office of Environment, Safety and Health must perform a 
semiannual analysis of all reportable occurrences during a 12-month period to look 
for trends.  In those cases where recurring events are discovered, these events must 
promptly and formally be brought to the attention of the Program Office(s) for 
identification of appropriate corrective actions. 
	
5.9	Training.  Specific training programs for the requirements of this Manual must be 
established for both DOE (including NNSA) and contractor personnel for facilities 
under their cognizance.  These training programs must include the following:

a.	Indoctrination in the objectives and process of occurrence reporting as defined in 
the occurrence reporting requirements documents. 

b.	Identification of reportable occurrences and their categorization, notification, and 
associated reporting requirements; analysis, determination, and coding of causes; 
identification of generic implications; and management of corrective actions.  

c.	Utilization of ORPS, including input of occurrence reports and obtaining 
information from the database.

d.	Utilization of the Causal Analysis Tree.

e.	Where applicable, the preparation of occurrence reports that may include 
classified information or unclassified controlled information (e.g., OUO or 
UCNI), including the sanitization of the report for entry into ORPS.

SECTION 6.  REPORTING CRITERIA.  

The following are the reporting criteria, categorized into 10 major groups and appropriate 
subgroups related to DOE operations.  This list provides a minimum set of requirements 
necessary to develop local procedures and report occurrences applicable to local operations.  
Categorization of occurrences must be done at the criterion level. 

	Site/contractor corrective action programs will manage actions for important events that do 
not meet the ORPS reporting herein (as well as Significance Category 4 occurrences, whose 
corrective actions are not managed through ORPS).  

	The reporting of safeguards and security events is addressed by DOE N 471.3, Reporting of 
Events of Security Concern.  Such events are no longer reported in ORPS unless they involve 
other consequences that met the ORPS reporting criteria presented herein.  

This Manual does not absolve the cognizant parties from making required reports to other 
agencies.

6.1	Major Criteria Groups.  The 10 major groups of categorized occurrences are as 
follows.
Group 1 - Operational Emergencies 
Group 2 - Personnel Safety 
Group 3 - Nuclear Safety Basis 
Group 4 - Facility Status 
Group 5 - Environmental 
Group 6 - Contamination/Radiation Control 
Group 7 - Nuclear Explosive Safety 
Group 8 - Transportation 
Group 9 - Noncompliance Notifications 
Group 10 - Management Concerns/Issues

6.2	Categorizing Instructions

1.	An event can meet multiple reporting criteria that establish it as an occurrence.  
All of the specific reporting criteria applicable for an occurrence must be 
identified.   Some criteria are "secondary" in that they complement other 
reporting criteria that require occurrence reporting. In these cases, all of the 
applicable criteria must be recorded.  Each criterion is denoted by its Group, 
Subgroup (if applicable), and sequence number (#).  Thus, for example, the 
violation of a safety limit is denoted as Group 3, Subgroup A, Sequence (1) or 
"3A(1)."

2.	The reporting criteria presented below list a specific Significance Category (SC) 
for each criterion, between the sequence number (#) and the criterion text.  
Significance Categories are designated as "OE" for Operational Emergencies,  
"R" for recurring occurrences, or 1, 2, 3, or 4.  Thus, for example, the 
Significance Category for a Stop Work Order issued by a DOE office, criterion 
4B(1), is SC 2. 

3.	Operational Emergencies, Significance Category 1, and some other occurrences in 
lesser significance categories require prompt notification to the DOE HQ OC.  
Asterisks (*) next to the significance categories below denote those 
occurrences requiring prompt notification to the DOE HQ OC.  Section 5.3.2 
of this Manual defines the prompt notification requirements.

4.	DOE O 151.1A describes initiating events that are considered Operational 
Emergencies.  DOE O 225.1A defines when Type A or B accident investigations 
should be initiated.  While some Operational Emergencies and some other ORPS 
occurrences involve conditions that would be sufficient to initiate accident 
investigations, criterion 10(1) herein will report the actual initiation of Type A or 
B accident investigations.  

6.3	Occurrence Reporting Criteria

Group 1 - Operational Emergencies

above limits established by the Occupational Safety and Health 
Administration (refer to 29 CFR Part 1910) or American 
Conference of Governmental Industrial Hygienists, whichever is 
lower, and that requires the administration of medical treatment 
beyond simple first aid on the same day as the exposure. [29 CFR 
1904.7(b)(5)(i) and (ii) define "medical treatment" and "first aid."] 

(5)	3	Personnel exposure to chemical, biological or physical hazards 
above limits established by the Occupational Safety and Health 
Administration (refer to 29 CFR Part 1910) or American 
Conference of Governmental Industrial Hygienists.

(6)	3	Any single occurrence resulting in a serious occupational injury.  
A serious occupational injury is an occupational injury that:

(a)	Requires hospitalization for more than 48 hours, 
commencing within 7 days from the date the injury was 
received; 

(b)	Results in a fracture of any bone (except simple fractures of 
fingers, toes, or nose, or a minor chipped tooth);

		[Note:  The activation or degradation of Safety Class and Safety 
Significant fire suppression systems are addressed by Group 4 
Criteria.]

(3)	*3	Any unplanned fire or explosion in a non-nuclear facility that 
a)	Activates a fire suppression system, 
b)	Takes longer than 10 minutes to extinguish following the 
arrival of fire protection personnel, or 
c)	Disrupts normal operations in a high hazard facility.

(4)	*4	Any wild land fire (e.g., forest fire, grassland fire) or other fire 
outside of a DOE facility that has the potential to threaten the 
facility.

Subgroup C	Hazardous Energy Control 

#	SC	Criterion

(1)	2	Failure to follow a prescribed hazardous energy control process 
(e.g., lockout/tagout) or disturbance of a previously unknown or 
mislocated hazardous energy source (e.g., live electrical power 
circuit, steam line, pressurized gas) resulting in a person contacting 
(burn, shock, etc.) hazardous energy.

(2)	3	Failure to follow a prescribed hazardous energy control process 
(e.g., lockout/tagout) or a site condition that results in the 
unexpected discovery of an uncontrolled hazardous energy source 
(e.g., live electrical power circuit, steam line, pressurized gas).  
This criterion does not include discoveries made by zero-energy 
checks and other precautionary investigations made before work is 
authorized to begin. 

Group 3 - Nuclear Safety Basis

#	SC	Criterion

(1)	*1	Any violation of a Hazard Category 1, 2, or 3 nuclear facility's 
Technical Safety Requirement (or Operational Safety 
Requirement) Safety Limit. 

[Note: Safety Limits are high-level Technical Safety Requirement 
controls, used infrequently across the DOE Complex. As defined 
in 10 CFR 830.3, a Safety Limit is a limit on process variables 
associated with those safety class physical barriers, generally 
passive, that are necessary for the intended facility function and 
that are required to guard against the uncontrolled release of 
radioactive materials.]

(2)	2	Any violation or noncompliance of a Hazard Category 1, 2, or 3 
nuclear facility's Technical Safety Requirement (or Operational 
Safety Requirement) Limiting Control Setting, Limiting Condition 
for Operation, Administrative Control, or Surveillance 
Requirement.

Exception: An event consisting solely of a surveillance test 
performed after the prescribed surveillance period, and in which 
the equipment was found to be capable of performing its specified 
safety function.  (See separate criterion for late surveillance tests 
below.)

(3)	3	Any violation or noncompliance of a hazard control specified in a 
Hazard Category 1, 2, or 3 nuclear facility's DOE approved 
Documented Safety Analysis [issued pursuant to 10 CFR 830.204

issued Safety Evaluation Report that are not addressed by Criteria 
3A(1) and 3A(2).

Exceptions:
(a)	An event consisting solely of a violation of a safety 
management program (e.g., quality assurance, personnel 
training) cited in the Documented Safety Analysis. 

(b)	An event consisting solely of a surveillance test performed 
after the prescribed surveillance period, and in which the 
equipment was found to be capable of performing its 
specified safety function.  (See separate criterion for late 
surveillance tests below.)

(4)	4	An event consisting solely of a surveillance test performed after 
the prescribed surveillance period, and in which the equipment was 
found to be capable of performing its specified safety function. 

Subgroup B	Documented Safety Analysis Inadequacies

#	SC	Criterion

(1)	2	Determination of a positive Unreviewed Safety Question (USQ) 
that reveals a currently existing inadequacy in the documented 
safety analysis [e.g., Safety Analysis Report (SAR) or Basis for 
Interim Operation (BIO)].

(2)	3	Declaration of a potential inadequacy of the documented safety 
analysis (a potential positive USQ), per 10 CFR 830.203(g).

such that an accidental criticality is possible from the loss of an 
additional process-condition control, where processes include 
operation, transport, and storage of fissionable materials.

Group 4 - Facility Status

[Note:  The criteria below apply to both nuclear and non-nuclear facilities, where 
applicable.]

Subgroup A	Safety Structure/System/Component Degradation

#	SC	Criterion

(1)	3	Performance degradation of any Safety Class or Safety Significant 
Structure, System, or Component (SSC) that prevents satisfactory 
performance of its design function when it is required to be 
operable. 

(2)	4	Performance degradation of any Safety Class SSC when not 
required to be operable.

Subgroup B	Operations

#	SC	Criterion

(1)	*2	A Stop Work Order issued by a DOE office. 

(2)	2	Actuation of a Safety Class Structure, System, or Component 
(SSC), or its alarms, resulting from an actual unsafe condition.  
Spurious alarms (e.g., due to electronic noise, radon/thoron decay) 
should not be reported. 

(3)	3	Actuation of a Safety Significant Structure, System, or Component 
(SSC), or its alarms, resulting from an actual unsafe condition.  
Spurious alarms (e.g., due to electronic noise, radon/thoron decay) 
should not be reported.

(4)	3	Any facility evacuation, not including a precautionary evacuation, 
in response to an actual event.  If the event fell under another 
reporting criterion, then evacuation should be reported as well by 
noting multiple reporting criteria for the single occurrence.

(5)	4	A facility operational event caused by deviating from a written 
procedure or using an inadequate procedure resulting in an adverse 
effect on safety, such as: an inadvertent facility or operations 
shutdown (i.e., a change of operational mode or curtailment of 
work or processes), facility or operations shutdown due to alarm 
response procedures, inadvertent process liquid transfer, or 
inadvertent release of hazardous material from its engineered 
containment.

(6)	*4	A facility or operations shutdown (i.e., a change of operational 
mode or curtailment of work or processes) directed by 
management for safety reasons.

(7)	4	A facility or site stand-down resulting from safety reasons 
reportable as an occurrence or occurrences.

[Note:  This is a secondary reporting criterion and does not require 
a separate occurrence report.]
 
(8)	4	Any event or condition that would prevent immediate facility or 
offsite emergency response capabilities.

Subgroup C	Suspect/Counterfeit and Defective Items or Material

#	SC	Criterion

(1)	3	Discovery of any suspect/counterfeit item or material found in a 
Safety Class or Safety Significant Structure, System, or 
Component (SSC).  

		A suspect item or material is one whose documentation, 
appearance, performance, material, or other characteristics may 
have been misrepresented by the vendor, supplier, distributor, or 
manufacturer.  A counterfeit item or material is one for which 
sufficient evidence exists that deliberate misrepresentation has 
occurred.

(2)	4	Discovery of any suspect/counterfeit item or material other than 
office supplies, office equipment, or household products.

(3)	4	Discovery of any defective item or material, other than a 
suspect/counterfeit item or material, in any application whose 
failure could result in a loss of safety function, or present a hazard 
to public or worker health and safety.

		A defective item or material is any item or material that does not 
meet the commercial standard or procurement requirements as 
defined by catalogues, proposals, procurement specifications, 
design specifications, testing requirements, contracts, or the like.  
It does not include parts or services that fail or are otherwise found 
to be inadequate because of random failures or errors within the 
accepted reliability level.  

Group 5 - Environmental

Subgroup A	Releases 

#	SC	Criterion

(1)	*2	Any release (onsite or offsite) of a hazardous substance, material,

(2)	2	Any discharge that exceeds 100 gallons of oil of any kind or in any 
form, including, but not limited to, petroleum, fuel oil, sludge, oil 
refuse, and oil mixed with wastes other than dredged spoil.  For 
operations involving oil field crude or condensate, any discharge of 
100 barrels or more is reportable under this criterion.

(3)	4	Any release (onsite or offsite) of a hazardous substance, material, 
waste, or radionuclide from a DOE facility that is above permitted 
levels and exceeds 50 percent of the reportable quantities specified 
in 40 CFR 302 or 40 CFR 355. 

(4	4	Any release (onsite or offsite) of a hazardous substance, material, 
waste, or radionuclide from a DOE facility that must be reported to 
outside agencies in a format other than routine periodic reports.  
(However, oil spills of less than 10 gallons and with negligible 
environmental impact need not be reported in ORPS.)
		 
Subgroup B	Ecological and Cultural Resources

#	SC	Criterion

(1)	2	Any occurrence causing significant impact to any ecological 
resource for which DOE is a trustee (e.g., destruction of a critical 
habitat, damage to an historic/archeological site, damage to 
wetlands).

Group 6 - Contamination/Radiation Control

Subgroup A	Loss of Control of Radioactive Materials

#	SC	Criterion

(1)	2  	Identification of radioactive material offsite due to DOE 
operations/activities that exceeds applicable DOE-approved 
authorized limits (pursuant to DOE O 5400.5).  This applies to 
items/areas consisting of radioactive material.  This does not apply 
to items with surface radioactive contamination.  See Criterion 
6B(1) below for criteria for identification of items with surface 
radioactive contamination.

(2)	2	Loss of radioactive material that exceeds 100 times the quantities 
specified in 10 CFR Part 835, Appendix E (excluding consumer 
products such as smoke detectors), or loss of accountability of such 
material for more than 24 hours.  The 24-hour time period begins 
when the loss of accountability is discovered.

(3)	3	Loss of radioactive material which exceeds 1 times and no greater 
than 100 times the quantities specified in 10 CFR Part 835, 
Appendix E (excluding consumer products such as smoke 
detectors) or loss of accountability of such material for more than 
24 hours. The 24-hour time period begins when the loss of 
accountability is discovered.

Subgroup B	Spread of Radioactive Contamination

#	SC	Criterion

(1)	2	Identification of radioactive contamination offsite due to DOE 
operations/activities that exceeds applicable DOE-approved 
authorized limits (pursuant to DOE 5400.5) or, if there are none, 
the values found in 10 CFR Part 835, Appendix D.

[Note:  All releases of property containing or potentially 
containing residual radioactivity are subject to requirements in 
DOE 5400.5.  Compliance with 10 CFR Part 835, Appendix D 
values does not necessarily satisfy the requirements in DOE 
5400.5.]

(2)	2	Identification of onsite radioactive contamination greater than 100 
times the total contamination values in 10 CFR 835 Appendix D 
and that is found outside of the following locations:  
Contamination Areas, High Contamination Areas, Airborne 
Radioactivity Areas, Radiological Buffer Areas, and areas 
controlled in accordance with 10 CFR 835.1102(c).  For tritium, 
the reporting threshold is 100 times the removable contamination 
values in 10 CFR Part 835, Appendix D.
[Notes: 
(a) This does not apply to contamination from residual 
radioactive material meeting applicable DOE-approved 
authorized limits. 
(b) This also does not apply to legacy radioactive 
contamination, which will be reported under a separate 
criterion below. 
(c) The exclusion from reporting contamination in a 
Radiological Buffer Area applies only when the area has 
been established next to a Contamination Area, High 
Contamination Area or Airborne Radioactivity Area and its 
exit requirements have adopted guidance from Article 
338.2 of DOE-STD-1098-99.]

(3)	3	Identification of onsite radioactive contamination greater than 10 
times the total contamination values in 10 CFR 835 Appendix D 
and that is found outside of the following locations:  
Contamination Areas, High Contamination Areas, Airborne 
Radioactivity Areas, Radiological Buffer Areas, and areas

		[Notes: 
(a) This does not apply to contamination from residual 
radioactive material meeting applicable DOE-approved 
authorized limits. 
(b) This also does not apply to legacy radioactive 
contamination, which will be reported under a separate 
criterion below. 
(c) The exclusion from reporting contamination in a Radiological 
Buffer Area applies only when the area has been established 
next to a Contamination Area, High Contamination Area or 
Airborne Radioactivity Area and its exit requirements have 
adopted guidance from Article 338.2 of DOE-STD-1098-99.]

controlled in accordance with 10 CFR 835.1102(c).  For tritium, 
the reporting threshold is 10 times the removable contamination 
values in 10 CFR Part 835, Appendix D.

[Notes: 

(a)	Legacy radioactive contamination is radioactive contamination 
resulting from historical operations that are unrelated to current 
activities.   
(b)	This does not apply to contamination from residual 
radioactive material meeting applicable DOE-approved 
authorized limits. 
(c) The exclusion from reporting contamination in a 
Radiological Buffer Area applies only when the area has 
been established next to a Contamination Area, High 
Contamination Area or Airborne Radioactivity Area and its

(*) next to the significance category].

SECTION 7.  INFORMATION SECURITY REQUIREMENTS.  

Occurrence Reports containing any classified information, Unclassified Controlled Nuclear 
Information (UCNI), or other controlled information must not be entered into the ORPS 
database.  Facility Managers must ensure that a review is performed prior to ORPS data entry 
to preclude contamination of the database with classified, UCNI, official use only, or other 
controlled information.  

Any ORPS report determined to be classified or controlled by current classification or 
control guidance must be submitted using the appropriate secure transmission means.  
However, with the exception of entry into the ORPS database, all other reporting 
requirements identified in this Manual must be met.  In addition, an unclassified version of 
the occurrence report that has been sanitized of all controlled information must be submitted 
to ORPS within the required time frames specified in Section 5. 

Implementing procedures should identify the requirements for distribution of reports 
containing classified or controlled information.  In those instances where UCNI data may still 
be present in the ORPS database, appropriate security procedures related to the handling of 
such data need to be followed.  

[Note: Occurrence reports involving incidents of counterintelligence concern (e.g., foreign 
persons, governments, organizations, entities or influence) will not be entered or referenced 
in the ORPS database.]

SECTION 8.  UTILIZATION OF REPORTABLE OCCURRENCE INFORMATION.

8.1	Operational Database.  The Office of Environment, Safety and Health (EH-1) is 
responsible for maintaining an unclassified central database, the Occurrence 
Reporting and Processing System (ORPS).  Occurrence Report documentation and 
distribution requirements will be satisfied by utilization of ORPS, with the exception 
of those involving classified information or UCNI.  Reports for occurrences involving 
classified information or UCNI will be prepared in written form.  After the classified 
information and UCNI is removed, the report must be entered into ORPS.  

8.2	Utilization.  Each Facility Manager must collect and disseminate to their personnel 
information from occurrences related to their facilities and similar DOE facilities.  
This information includes both lessons learned and good practices.  Each Facility 
Manager should use this information for trending and analysis and for early 
identification and correction of deteriorating conditions.  

One of the major purposes of this reporting system is to provide feedback of safety 
and operational information identified in the Occurrence Reports to other DOE 
facilities.  In addition, Headquarters oversight and assessment organizations should 
use ORPS information to prepare Safety Notices and other feedback documents.  
These uses are dependent on the quality of the information reported, which means the 
information should be thorough and accurate.  To this end, Occurrence Reports 
should contain sufficient information about the facility operations and the occurrence 
to facilitate action by other personnel who are unfamiliar with details of the facility, 
equipment, process, or procedures.

Operations and engineering units, as well as other support organizations, should be 
involved in the identification and assessment of reportable occurrences.  Site 
information, such as operations logs and engineering evaluations, should be used in 
this process.

Engineering judgment should be used during the review of events and conditions to 
ensure that precursors to occurrences are identified and reported.  An occurrence that 
is not serious, given the conditions under which it happened, might under different 
initial conditions be a precursor to a serious event at the same or other facilities.

SECTION 9.  IMPLEMENTING PROCEDURES.  

Contractors at facilities must develop and maintain implementing procedures for the 
occurrence reporting and utilization requirements stated in this Manual within 90-days of the 
requirements in the Contractor Requirements Document being incorporated into their 
contracts.  For DOE-owned and -operated facilities, the responsible DOE organization must 
implement the requirements of this Manual within 90-days of the Manual approval date.  

SECTION 10.  INSTRUCTIONS FOR COMPLETING AN OCCURRENCE REPORT.  

Specific instructions on the reporting of occurrences via hard copy or the electronic database, 
the Occurrence Reporting and Processing System (ORPS), are listed in DOE G 231.1-1, 
Occurrence Reporting and Performance Analysis Guide.  The documentation and 
distribution requirements of this Manual will be satisfied by utilization of ORPS.  All reports 
containing classified information or Unclassified Controlled Nuclear Information (UCNI) 
must be submitted in hard copy in accordance with established security requirements (see 
Section 7).  In addition, an unclassified version of the Occurrence Report that has been 
sanitized of all controlled information must be submitted to ORPS within the time frames 
specified in Section 5.

CONTRACTOR REQUIREMENTS DOCUMENT

DOE M 231.1-2, Occurrence Reporting and Processing of Operations Information

Regardless of the performer of the work, the contractor is responsible for compliance with the 
requirements of this CRD.  The contractor is responsible for flowing down the requirements of this 
CRD to subcontracts at any tier to the extent necessary to ensure the contractor's compliance with the 
requirements.  In doing so, the contractor must not unnecessarily or imprudently flow down 
requirements to subcontracts.  That is, the contractor will both ensure that it and its subcontractors 
comply with the requirements of this CRD and only incur costs that would be incurred by a prudent 
person in the conduct of competitive business. 

SECTION 1.  OCCURRENCE REPORTING

For reportable occurrences, contractors must categorize the occurrences, notify DOE as required, 
and prepare and submit Occurrence Reports.  At sites with more than one facility management 
contractor, contractors may make arrangements for one of the contractors to prepare and submit 
reports for the entire site.  However, each contractor is responsible for ensuring that Occurrence 
Reports are submitted for activities within its scope of work.

The documentation and distribution requirements will be satisfied by utilization of a centralized 
unclassified DOE operational database, the computerized Occurrence Reporting and Processing 
System (ORPS).  However, under no circumstances will Occurrence Reports containing classified 
information or Unclassified Controlled Nuclear Information (UCNI) be entered into the ORPS 
database.  Requirements regarding security classification are provided in Section 3.

Occurrences involving foreign personnel, governments, organizations, entities or influence must be 
reported by the contractor to the Office of Counterintelligence or the Office of Defense Nuclear 
Counterintelligence, as appropriate. Such reporting is not intended to interfere with or delay any 
actions directed toward protection of personnel or property.

1.1	Event or Condition Identification.

a.	The contractor may identify occurrences by direct observation of equipment or process 
malfunctions, log or record reviews, operator recognition of their own or others' errors, 
or other means.

b.	The contractor must take appropriate immediate action to stabilize and/or place the 
facility/operation in a safe condition and ensure that any potential environmental effects 
are stabilized and workers are treated for injuries sustained.  Also, actions should be 
taken to preserve conditions for continued investigation; however, these actions are not 
to interfere with establishing a safe condition.

c.	The contractor must, upon identification of an abnormal or suspected abnormal event or 
condition, promptly notify the appropriate contractor line management of the event 
status and record and/or archive all pertinent information, including details concerning 
the discovery of the occurrence and actions taken to stabilize or place the 
facility/operation in a safe condition. 

1.2	Event or Condition Categorization.  The contractor must categorize all occurrences, except 
Operational Emergencies, within 2 hours of discovery following the site/facility-specific 
procedures developed in accordance with this CRD.  The significance categories [outlined 
in the Occurrence Reporting Model, Section 11 of DOE M 231.1-2] are for those 
occurrences of interest for complex-wide occurrence reporting and are described very 
generally below.  More definitively, Reporting Criteria, listed in Section 2 below, provide 
very specific reporting criteria and assigns the appropriate significance category to each 
criterion.  Local implementing procedures may increase the reporting requirements but may 
not decrease the requirements below.

a.	Operational Emergencies (OE).  Operational Emergency Occurrences are the most 
serious occurrences and require an increased alert status for onsite personnel and, in 
specified cases, for offsite authorities. [Operational Emergencies are defined in DOE O 
151.1A, Comprehensive Emergency Management System.  The prompt notification 
requirements, definitions, criteria, and classifications of operational emergencies and 
appropriate responses are provided in DOE O 151.1A.]  Written Occurrence Reports, 
however, must be completed in accordance with this CRD.  

b.	Significance Category 1.  Occurrences in this category are those that are not Operational 
Emergencies and that have a significant impact on safe facility operations, worker or 
public safety and health, regulatory compliance, or public/business interests.

c.	Significance Category R.  Occurrences in this category are those identified as recurring, 
as determined from the periodic performance analysis of occurrences across a site.

d.	Significance Category 2.  Occurrences in this category are those that are not Operational 
Emergencies and that have a moderate impact on safe facility operations, worker or 
public safety and health, regulatory compliance, or public/business interests.

e.	Significance Category 3.  Occurrences in this category are those that are not Operational 
Emergencies and that have a minor impact on safe facility operations, worker or public 
safety and health, regulatory compliance, or public/business interests

f.	Significance Category 4.  Occurrences in this category are those that are not Operational 
Emergencies and that have some impact on safe facility operations, worker or public 
safety and health, public/business interests.
 
If the consequences are not fully determined or the event exceeds the threshold of more than 
one criterion (listed in Section 2 below), then the event must be categorized at the higher 
criteria level being considered.  The occurrence criterion must be elevated, maintained, or 
lowered, as information is made available.  

1.3	DOE HQ Operations Center Prompt Notifications.

1.3.1	Operational Emergencies.  If an event has been declared an Operational Emergency, 
the contractor will be responsible for the written Notification Report and for the 
completion of all other occurrence reporting requirements, as described below. [The 
requirements for the prompt and follow-up notifications to DOE and other agencies 
and the appropriate emergency responses to be taken are provided in DOE O 151.1A, 
Comprehensive Emergency Management System.  The specific procedures on how 
these events are categorized and how and when DOE is notified are included in the 
site/facility-specific emergency response plans or procedures. ]

1.3.2	Prompt Notifications for Significance Category 1, 2, 3, and 4 Reportable Occurrences.  

a.	The contractor must notify the DOE Facility Representative (an individual 
designated by the Head of the Field Element/Operations Organization) in a 
manner determined locally and the DOE Headquarters Operations Center (DOE 
HQ OC), as required, of the following reportable occurrences as soon as practical 
(i.e., promptly), but no later than 2 hours after categorization:

1)	All Significance Category 1 occurrences require a prompt notification to the 
Facility Representative and DOE HQ OC.

2)	All Significance Category 2 occurrences require a prompt notification to the 
Facility Representative and, if directed by the Facility Representative, to the 
DOE HQ OC.

3)	All Significance Category 3 occurrences require a prompt notification to the 
Facility Representative.

4)	Additionally, specific Significance Category 2, 3, and 4 occurrences 
(identified as requiring prompt notification with an asterisk in the reporting 
criteria listed in Section 2 below) require prompt notification to the Facility 
Representative and DOE HQ OC.

b.	The contractor may use the local Field/Site Emergency Operations Center to 
expedite establishing the communication link required and to record and archive 
conversations.  The prompt notification process is, as follows:

1)	The contractor must e-mail the prompt notification of the reportable 
occurrence to the DOE HQ OC, and follow up with a phone call to the DOE 
HQ OC to ensure receipt of the e-mail and to clarify any areas that may not 
be clear.  

2)	The Prompt Notification must clearly state/select the Significance Category 
(1, R, 2, 3, or 4) and identify the specific reporting criteria associated with 
the occurrence. 

3)	Prompt Notification to the DOE HQ OC must include information on the 
following items:

a)	Occurrence Significance Category 
b)	Location and description of the event 
c)	Date and time of discovery 
d)	Damage and casualties 
e)	Impact of event on other activities and operations 
f)	Protective actions taken or recommended 
g)	Weather conditions at the scene 
h)	Level of media interest at scene/facility/site.
i)	Other notifications made

4)	All information should be clear and succinct.  Avoid jargon.  Uncommon or 
site/facility-specific abbreviations and acronyms should be fully described.

5)	The contractor must follow the appropriate security procedures if the 
notification to DOE may contain classified or sensitive information.

6)	If the occurrence is recategorized, then the occurrence must be reconsidered 
for prompt notification.  If appropriate, the contractor must notify the Facility 
Representative and the DOE HQ OC as soon as practical, but within the 
prompt notification time requirements of the new Significance Category for 
the recategorized occurrence and provide the Occurrence Report number. 

7)	Follow-up notifications must be made to DOE for any further degradation in 
the level of safety or impact on the environment, health, or operations of the 
facility or other worsening conditions subsequent to the previous notification.  
If a degradation results in upgrading the event to an Operational Emergency, 
the DOE HQ OC must be notified.  [See DOE O 151.1A, Comprehensive 
Emergency Management System.]

1.4	Written Notification Report. The contractor must prepare the written Notification Report 
(including all required fields and all other fields for which information is known) [described 
in DOE G 231.1-1, Occurrence Reporting and Performance Analysis Guide] and distribute 
it per Section 1.6.e below.  Direct entry into the computerized Occurrence Reporting and 
Processing System (ORPS) satisfies this requirement.  Any changes in the reporting criteria 
of the occurrence, which result in a change, either lower or higher, to the Significance 
Category, must be documented in an Update Report and submitted within the timeframe 
required for the Notification Report under the new Significance Category.  A discussion on 
the change in categorization must be included in the Description of Occurrence field in the 
Update Report.

1.4.1	Occurrence Report Preparation.  In preparing the Notification Report, and 
subsequently the Final Report, the following writing instructions must be followed:

a.	The report should enable the general reader to understand the basic "what, who, 
when, where, how" of the event, the safety issues involved, and the actions 
taken.

b.	The Subject/Title and the first paragraph of the Occurrence Description should 
relay the essential nature of the event (i.e., a summary of the occurrence in 
newspaper style).

c.	All information should be clear and succinct.  Avoid redundant and unnecessary 
text, and lengthy "log book" accounts, unless a discussion of the event in 
chronological order is considered essential to understanding the event.

d.	Complex and more significant occurrences should warrant a greater level of 
detail.  Significance Category 4 occurrences would likely need only a short 
paragraph under Occurrence Description.  However, all reports should present 
enough information so that the general reader understands why the event needs 
to be reported and what the effect is.

e.	Avoid jargon and uncommon or site/facility-specific abbreviations and 
acronyms.  If used, acronyms should be initially spelled out. 

f.	Unless necessary to record and explain the event (e.g., suspect/counterfeit items 
or material), use general descriptions of equipment, procedures, etc., rather than 
presenting lengthy detailed titles and the numbers and letters assigned to those 
items.  

g.	Quantify the level of contamination, dose, release, and damage (e.g., estimate the 
acres of wild land burned) when possible, instead of merely stating a reportable 
limit was exceeded.    

h.	Use active rather than passive voice whenever possible. For example, write, "the 
electrician severed the conduit" rather than "the conduit was severed."

i.	When appropriate for clarification, photos, sketches, and drawings must be 
maintained with the ORPS occurrence report record.  In addition, sites are 
encouraged but not required to make photos, sketches, and drawings available 
via a Web page, with the Web page address included as a hyperlink in the ORPS 
report.

1.4.2	Notification Report Submittal Schedule.  The written Notification Report must be 
submitted according to the following schedule:
 
a.	Reports for Operational Emergencies and Significance Category 1 Occurrences.  
Before the close of the next business day from the time of categorization (not to 
exceed 80 hours).  

b.	Reports for Significance Categories R and 2 Occurrences.  Before the close of 
the next business day from the time of categorization.  

c.	Reports for Significance Category 3 Occurrences.  No later than close of 
business on the second business day from the time of categorization.

d.	Reports for Significance Category 4 Occurrences.  Only a Short Form Report is 
required by close of business the second business day from the time of 
categorization. 

1.5	Occurrence Investigation and Analysis.  The following steps describe an acceptable process 
for submitting Update Reports and conducting the investigation and analysis of a specific 
occurrence. [DOE 5480.19, Conduct Of Operations Requirements For DOE Facilities, and 
DOE-STD-1045-93, Guide to Good Practices for Notifications and Investigation of 
Abnormal Events, should be considered when establishing a program for investigation of 
occurrences.  In cases of conflict between DOE 5480.19 or DOE-STD-1045-93 and this 
CRD, the requirements of this CRD must be followed.]

In general, the investigative process is used to gain an understanding of the occurrence, its 
causes, and the corrective actions necessary to prevent recurrence or only remedy the 
problem, based on the significance of the occurrence.  If DOE is doing a Type A or B 
investigation [defined in DOE O 225.1A], the contractor is not required to perform an 
identical investigation.  [However, the contractor is still required to do the preliminary 
assembly of information to turn over to the DOE Accident Investigation Board, in 
accordance with DOE O 225.1A, Accident Investigation.]

a.	The contractor should use a graded approach [described in the Occurrence Reporting 
Model, Section 11 of DOE M 231.1-2] when determining the level of effort required 
for the investigation into the causes of the occurrence.  This graded approach is based 
on the significance, severity, or risk associated with the event or condition.

For Operational Emergencies, in general, the investigation, problem analysis, and 
corrective action process should parallel the process for Significance Category 1 
occurrences.  However, the contractor should consider a graded approach when 
determining the level of effort for the investigation into the cause of the Operational 
Emergency.  For this purpose, the graded approach is based on whether the 
Operational Emergency was directly caused by DOE operations or resulted from non-
DOE operations or natural phenomena.  For example, investigations of an Operational 
Emergency involving the release of hazardous materials might require an accident 
investigation or the assembly of a team of investigators and subject matter experts.  
Investigation of an Operational Emergency resulting from a DOE facility being 
required to implement protective actions because a non-DOE activity offsite released 
hazardous materials or an Operational Emergency resulting from an earthquake may 
not require root cause determination because the initiating event was clearly beyond 
DOE's control.  

b.	All causes must be identified as required and included in the occurrence report.  [See 
the Occurrence Reporting Model, Section 11 of DOE M 231.1-2.  The cause codes to 
be used for reporting are provided in the Causal Analysis Tree, also in Section 11.  
Guidance on selecting the appropriate cause code is provided in DOE G 231.1-2, 
Occurrence Reporting Causal Analysis Guide.]  The Cause Description field should 
include a brief discussion to clearly link the event to the cause code(s).  For those 
occurrences that require a formal root cause analysis, any of the site approved root 
cause analysis methodologies are permitted.  The methodology used must be included 
in the Cause Description field of the occurrence report.  Additionally, the Cause 
Description Field must include a brief discussion to describe the linkage of the 
identified cause codes to the associated causal factors for the event.  In addition to 
determining the causes of the occurrence, any weaknesses in the facility's 
implementation of the ISM program must be identified and entered in the ISM field, as 
discussed in DOE G 231.1-1, Occurrence Reporting and Performance Analysis Guide.

c.	In addition to submitting an Update Report when the Significance Category of the 
occurrence has been changed (as stated in Section 1.4), the contractor must submit and 
distribute an Update Report for all occurrences, with the exception of Significance 
Category 4 occurrences, if there is any significant and new information about the 
occurrence.  The status of the investigation, recurring consequences, and the 
identification of additional component defects are activities associated with the 
occurrence and must be included in Update Reports. 

d.	Using a graded approach as described in the Occurrence Reporting Model (see Section 
11, DOE M 231.1-2), the contractor should consult in a timely manner with the 
Facility Representative and the Program Manager, as appropriate, for their assessment, 
if any, of the occurrence.

1.6	Occurrence Report Closure.  The following steps describe an acceptable process for closing 
out the Final Report for all occurrences except those categorized as Significance Category 4:

a.	The Final Report must be prepared by the contractor and submitted as soon as 
practical but within 45 calendar days after initial categorization of the occurrence. The 
Final Report must be prepared using the writing instructions listed in Section 1.4.1 and 
must document the following:

(1)	The significance, nature, and extent of the event or condition;

(2)	The causes of the event or condition (including the root cause, as required), using 
the codes provided in the Causal Analysis Tree (see Section 11, DOE M 231.1-
2); 

(3)	The immediate actions taken and the corrective action(s) to be taken, as required 
by the Occurrence Reporting Model (see Section 11, DOE M 231.1-2); and

(4)	The lessons learned.

b.	If the required analysis cannot be completed within 45 calendar days after initial 
categorization, an Update Report must be submitted within the 45 days.  The Update 
Report must provide a detailed explanation of the delay and provide an estimated date 
for submittal of the Final Report.  This information must be reported in the 
"Evaluation" block of the Occurrence Report.  It is expected that the analysis of most 
occurrences will be completed and the Final Report submitted within the 45 calendar 
days.  However, for certain occurrences, such as those requiring an accident 
investigation, it is understood that the information required for the Final Report may 
not be available within this time.  For occurrences resulting in an accident 
investigation, all causes (direct, contributing, and root) identified in the accident 
investigation report, as well as the corrective actions developed in response to the 
judgments of need, must be included in the Final Report. 

c.	If the Final Report is not approved by the Facility Representative or the Program 
Manager as appropriate, then the contractor must submit the revised Final Report 
within 21 calendar days of the disapproval.  If it cannot be resubmitted within this 
time, an Update Report must be submitted within the 21 calendar days explaining the 
delay and providing an estimated date for resubmittal of the Final Report.  This 
information must be reported in the "Evaluation" block of the Occurrence Report.

d.	All Occurrence Reports must be distributed as soon as practical to the following:

-	Facility Representative
-	Program Manager 
-	Heads of all Field organizations (including NNSA)
-	Office of Environment, Safety and Health (Office of Performance Assessment and 
Analysis) and Administrator (NNSA) and
-	DOE Management and Operations or Integrating contractors

If the Occurrence Reports are entered into the ORPS database, the distribution 
requirement is automatically satisfied.  

e.	Depending on the Significance Category, the contractor must track all corrective 
actions to closure, including independent verification or sampling of corrective actions 
identified to prevent recurrence, at the facility level and also evaluate the effectiveness 
of the corrective actions to prevent recurrence (if applicable).  Site/contractor 
corrective action programs will include management of Significance Category 4 
occurrences, whose corrective actions are not managed through ORPS.  

The cognizant contractor may use the ORPS database to track the status of Final 
Report corrective actions.  For those facilities that do not choose to use ORPS to track 
the status of their corrective actions, the specific corrective action tracking number 
from the local corrective action tracking system must be entered into ORPS.  Any 
changes made to the corrective actions tracked in the local corrective action system 
must follow the site's approved change process and should be updated in ORPS.  For 
Significance Category 2 and higher reports, any text change to a corrective action 
previously entered in ORPS must be updated in ORPS with Facility Representative 
approval.  A status report of all incomplete Occurrence Reports (not Final) and 
incomplete corrective actions (for those sites who choose to track the status of their 
corrective actions using ORPS) will be available at any time from the ORPS database.

f.	Retain all supporting information pertaining to each occurrence or report (e.g., graphs, 
analyses, and formal investigation reports). [See Departmental Records Disposition 
Schedules, in 36 CFR Chapter 12, Subchapter B, RECORDS MANAGEMENT.]

1.7	Short Form Reports.  A Short Form Report must be prepared and submitted for all 
Significance Category 4 occurrences no later than 2 business days after categorization of the 
occurrence. [Short Form report is described further in DOE G 231.1-1, Occurrence 
Reporting and Performance Analysis Guide.]  This report will satisfy all of the written 
reporting requirements for these occurrences.

1.8 	Performance Analyses and Identification of Recurring Occurrences.  Each contractor at a 
site must perform ongoing, but as a minimum quarterly, analyses of events during a 12-
month period to look for trends.  This periodic performance analysis must evaluate 
occurrences of all significance categories plus contractor-determined non-reportable events 
in order to prevent serious events from occurring.   Contractors must report quarterly 
performance analysis results to contractor and DOE line management in order to achieve 
improvements.

Occurrences identified as recurring must be submitted by the contractor as a new occurrence 
report for notification of the recurring issue, with investigation, root cause analysis, and 
corrective actions identified.  Previous individual Occurrence Report Numbers associated 
with the recurring issue must be provided in the Similar Occurrence Report Numbers field.  
The reporting organization should select the appropriate reporting criteria associated with 
the recurring issue.  If no specific reporting criteria can be identified, the Reporting Criteria 
should be listed as Group 10, Criteria #2. 

Recurring occurrences must be categorized and reported collectively as a Significance 
Category R occurrence, even if each individual occurrence had been originally categorized 
at a higher or lower significance level (e.g., as Significance Category 1 or 4 or even as non-
reportable occurrences). [See Occurrence Reporting Model, Section 11 of DOE M 231.1-2, 
requirements for a Significance Category "R" occurrence.  More information on the 
performance analysis requirements for all occurrence reports and specifics on recurring 
occurrences are provided in DOE G 231.1-1, Occurrence Reporting and Performance 
Analysis Guide.]

1.9	Training.  Appropriate training programs for the requirements of this CRD must be 
established for contractor personnel.  These training programs must include the following:

a.	Indoctrination in the objectives and process of occurrence reporting as defined in the 
occurrence reporting requirements documents. 

b.	Identification of reportable occurrences and their categorization, notification, and 
associated reporting requirements; analysis, determination, and coding of causes; 
identification of generic implications; and management of corrective actions.  

c.	Utilization of ORPS, including input of occurrence reports and obtaining information 
from the database.

d.	Utilization of the Causal Analysis Tree (see Section 11, DOE M 231.1-2).

e.	Where applicable, the preparation of occurrence reports that may include classified 
information or unclassified controlled information (e.g. OUO or UCNI), including the 
sanitization of the report for entry into ORPS.

SECTION 2.  REPORTING CRITERIA.  

The following are the reporting criteria, categorized into 10 major groups and appropriate 
subgroups related to DOE operations.  This list provides a minimum set of requirements necessary 
to develop local procedures and report occurrences applicable to local operations.  Categorization of 
occurrences must be done at the criterion level. 

	Contractor corrective action programs will manage actions for important events that do not meet the 
ORPS reporting herein (as well as Significance Category 4 occurrences, whose corrective actions 
are not managed through ORPS).  

	The reporting of safeguards and security events is addressed by DOE N 471.3, Reporting of Events 
of Security Concern.  Such events are no longer reported in ORPS unless they involve other 
consequences that met the ORPS reporting criteria presented herein.  

This Manual does not absolve the cognizant parties from making required reports to other agencies.

2.1	Major Criteria Groups.  The 10 major groups of categorized occurrences are as follows.
Group 1 - Operational Emergencies 
Group 2 - Personnel Safety 
Group 3 - Nuclear Safety Basis 
Group 4 - Facility Status 
Group 5 - Environmental 
Group 6 - Contamination/Radiation Control 
Group 7 - Nuclear Explosive Safety 
Group 8 - Transportation 
Group 9 - Noncompliance Notifications 
Group 10 - Management Concerns/Issues

2.2	Categorizing Instructions

1.	An event can meet multiple reporting criteria that establish it as an occurrence.  All of 
the specific reporting criteria applicable for an occurrence must be identified.   
Some criteria are "secondary" in that they compliment other reporting criteria that 
require occurrence reporting.  In these cases, all of the applicable criteria must be 
recorded.  Each criterion is denoted by its Group, Subgroup (if applicable), and sequence 
number (#).  Thus, for example, the violation of a safety limit is denoted as Group 3, 
Subgroup A, Sequence (1) or "3A(1)."

2.	The reporting criteria presented below list a specific Significance Category (SC) for 
each criterion, between the sequence number (#) and the criterion text.  Significance 
Categories are designated as "OE" for Operational Emergencies,  "R" for recurring 
occurrences, or 1, 2, 3, or 4.  Thus, for example, the Significance Category for a Stop 
Work Order issued by a DOE office, criterion 4B(1), is SC 2. 

3.	Operational Emergencies, Significance Category 1, and some other occurrences in lesser 
significance categories require prompt notification to the DOE HQ OC.  Asterisks (*) 
next to the significance categories below denote those occurrences requiring 
prompt notification to the DOE
