BP Amoco Naperville Complex, Illinois 
EPA Risk Management Plan - Executive Summary 
The BP Amoco Naperville Complex facility has a long-standing commitment to worker and public safety.  
This commitment is demonstrated by the resources invested in accident prevention, such as training  
personnel and considering safety in the design, installation, operation and maintenance of our processes. 
Our facility adheres to process safety policies, guidelines, and best practices that have been developed  
based on company and industry experience over the years.  Our policy is to implement reasonable  
controls to prevent foreseeable releases of regulated substances.  However, if a release does occur, our  
trained personnel will respond to control and contain the incident. 
The BP Amoco Naperville Complex is located at 150 West Warrenville Road, Naperville, Illinois 60563.   
The facility is owned by BP Amoco C 
orporation.  The primary purpose of the facility is to conduct both 
petroleum and chemical research and development.  A secondary purpose is to provide office space for  
a other BP Amoco employees unrelated to the research and development activities.  At present, the  
facility has only one process -- the 300 Tank Farm -- which is subject to the Clean Air Act Risk  
Management Planning requirements.  This process contains three flammable regulated substances  
which are in excess of the threshold quantity as follows:  isobutylene mixture, propylene and  
ethylene.  Please note that the BP Amoco Naperville Complex has no regulated toxic substances in  
excess of  the threshold quantity. 
Worst Case Scenario 
The worst case scenario (WCS) for flammable substances is a vapor cloud explosion (VCE) with an  
overpressure endpoint of 1 pound per square inch (psi).  The WCS endpoint is based on the  
instantaneous release of the entire contents isobutylene (60,000 pounds) from t 
he 300 Tank Farm  
resulting in a VCE.  The effects of administrative controls, mitigation systems, and safety systems are  
not included in determining the effects of a VCE.  Distances to the endpoint were calculated using the  
methodology outlined in EPAs RMP Offsite Consequence Analysis Guidance.  Nearby public receptors  
could be affected by this type of release.  Specific information on this release is presented in more detail  
in this document. 
Alternative Release Scenarios  
The alternative release scenario for flammable substances at the facility is a VCE resulting from the  
release of propylene through a relief valve at the 300 Tank Farm.  It is not anticipated that this release 
would travel beyond property boundaries.  However, operators would still respond to the situation in a  
timely manner. Specific information on this release is presented in more detail in the plan. 
The following is a summary of the accident prevention program in place at the BP Amo 
co Naperville  
Complex for all EPA RMP covered processes, presently only the 300 Tank Farm.  Since this process is  
also regulated by the OSHA PSM standard, this summary is organized in the format of the OSHA PSM  
Employee Participation 
The BP Amoco Naperville Complex encourages employees who work at the 300 Tank Farm to participate  
in multiple facets of process safety management and accident prevention.  Examples of employee  
participation range from updating and compiling technical information to participating as a member of a  
process hazard analysis (PHA) team.  Employees have access to all information created as part of the  
facility prevention program. Specific ways that employees can be involved are documented in the  
employee participation plan. 
Process Safety Information 
The personnel at the 300 Tank Farm keep a variety of technical documents that are used to help maintain safe 
operation.  These documents address chemical properties and associated hazards, limit 
s for key 
process parameters and specific chemical inventories, and equipment design basis/configuration 
information.  The 300 Tank Farm has documentation available showing the location of this information 
to help employees and visitors locate any necessary process safety information.  
Chemical specific information, including exposure hazards and emergency response/exposure treatment 
considerations, is provided in material safety data sheets (MSDSs).  This information is supplemented by 
documents that specifically address known exposure concerns and any known hazards associated with  
the inadvertent mixing of chemicals.  The 300 Tank Farm has documented safety-related limits for  
specific process parameters.  The 300 Tank Farm personnel help assure that the process is maintained  
within these limits using process controls and monitoring instruments, trained personnel, and protective  
instrument systems.  In addition, information is available summarizing the consequences of deviation  
from these limits and the corrective actions to take. 
The 300 Tank Farm also maintains technical documents that provide information about the design and  
construction of process equipment.  This information includes materials of construction, design pressure 
and temperature ratings, electrical ratings of equipment, piping and instrument drawings, etc.  This  
information, in combination with written procedures and trained personnel, provides a basis for  
establishing inspection and maintenance activities, as well as for evaluating proposed process and  
facility changes to ensure that safety features in the process are not compromised. 
Process Hazard Analysis 
The BP Amoco Naperville Complex has a program to help ensure that hazards associated with the 
various processes are identified and controlled.  This process applies to the 300 Tank Farm.   Within this 
program, each process is systematically examined to identify hazards and ensure that adequate controls 
are in place to manage the 
se hazards. 
The BP Amoco Naperville Complex primarily uses the hazard and operability (HAZOP) analysis  
technique to perform these evaluations.  HAZOP analysis is recognized as one of the most systematic  
and thorough hazard evaluation techniques.  The analyses are conducted using a team of people who  
have operating and maintenance experience as well as engineering expertise.  This team identifies and  
evaluates hazards of the process as well as accident prevention and mitigation measures, and makes  
suggestions for additional prevention and/or mitigation measures when the team believes such measures 
are necessary. 
The PHA teams recommendations are forwarded to management for resolution.  These  
recommendations are reviewed and all approved recommendations are tracked until they are completed. 
The final resolution of each recommendation is documented and retained.    
To help ensure that the process controls and or process hazards do not eventually deviate significantly 
from the or 
iginal design safety features, the BP Amoco Naperville Complex periodically updates and  
revalidates the hazard analysis results.  These periodic reviews are conducted at least every five years  
as long as the process exists.  The recommendations from these updates are also forwarded to  
management.  Final resolution of the recommendations is tracked, documented, and retained.   
Operating Procedures 
The BP Amoco Naperville Complex maintains written procedures that address the operation of the 300 
Tank Farm.  These procedures are developed/revised by experienced operators as needed and provide  
a basis for consistent training of new operators.  The procedures are periodically reviewed and annually  
certified as current and accurate.  The procedures are revised as necessary to reflect changes made  
through the management of change process. 
The BP Amoco Naperville Complex has established safe work practices in place to help ensure worker 
and process safety.  Examples of these include ( 
1) control of site entry/presence/exit of support  
personnel, (2) a lockout procedure to ensure isolation of energy sources for equipment undergoing  
maintenance, (3) a procedure for safe removal of hazardous materials before process piping or  
equipment is opened, and (4) a permit and procedure to ensure that adequate precautions are in place  
before entry into a confined space.  These procedures (and others), along with training of affected  
personnel, form a system to help ensure that research and maintenance activities are performed safely. 
To complement the written procedures for process operations, the BP Amoco Naperville Complex has  
implemented a comprehensive training program for all employees involved in operating a process.  New  
employees receive basic training in research and development  operations.  After successfully  
completing this training, a new operator is paired with a senior operator to learn process-specific duties  
and tasks.  After the new operator  
demonstrates (i.e. through tests, skills demonstration, etc.) adequate  
knowledge to perform the duties and tasks in a safe manner on their own, they can work independently.   
In addition, all operators periodically receive refresher training on the operating procedures to ensure  
that their skills and knowledge are maintained at an acceptable level.  This refresher training is conducted 
at least every three years.  All of this training is documented, including the means used to verify that the  
operator understood the training. 
The BP Amoco Naperville Complex routinely uses contractors to supplement maintenance, construction  
and operation efforts.  Because some contractors work on or near process equipment, the facility has  
procedures in place to help ensure that contractors (1) perform their work in a safe manner, (2) have the  
appropriate knowledge and skills, (3) are aware of the hazards in their workplace, (4) understand what  
they should do in the event of an emer 
gency, (5) understand and follow site safety rules, and (6) inform  
facility personnel of any hazards that they find during their work.  This is accomplished by providing  
contractors with (1) a process overview, (2) information about safety and health hazards, (3) emergency  
response plan requirements, and (4) safe work practices prior to work starting.  In addition, the BP 
Amoco Naperville Complex evaluates contractor safety programs and performance during the selection  
of a contractor.  Facility personnel periodically monitor contractor performance to ensure that contractors 
are fulfilling their safety obligations. 
Pre-Startup Safety Reviews (PSSRs) 
The BP Amoco Naperville Complex conducts a PSSR for any new facility or facility modification that 
requires a change in the process safety information.  The purpose of the PSSR is to ensure that safety 
features, equipment, procedures, and personnel are appropriately prepared for startup prior to placing  
the equipment into service.   
This review provides one additional check to make sure construction is in 
accordance with the design specifications and that all supporting systems are operationally ready.  The  
PSSR review team uses checklists to verify all aspects of readiness.  A PSSR involves field verification  
of the construction and serves a quality assurance function by requiring verification that accident  
prevention program requirements are properly implemented. 
Mechanical Integrity 
The BP Amoco Naperville Complex has practices and procedures to maintain pressure vessels, piping  
ystems, relief and vent systems, controls, pumps and compressors, and emergency shutdown systems 
in a safe operating condition.  The basic aspects of this program include: (1) conducting training,  
(2) developing written procedures and plans, (3) performing inspections and tests, (4) correcting  
identified deficiencies, and (5) applying quality assurance measures.  In combination these activities  
form a system that maintains the  
mechanical integrity of the process equipment. 
Maintenance personnel receive training on (1) an overview of the process, (2) safety and health hazards, 
(3) applicable maintenance procedures, (4) emergency response plans, and (5) applicable safe work  
practices to help ensure that they can perform their job in a safe manner.  Written procedures help  
ensure that work is performed in a consistent manner and provide a basis for training.  Inspections and 
tests are performed to help ensure that equipment functions as intended, and to verify that equipment is  
within acceptable limits (i.e. adequate wall thickness for pressure vessels).  If a deficiency is identified,  
employees will correct the deficiency before placing the equipment back into service (if possible), or an  
MOC team will review the use of the equipment and determine what actions are necessary to ensure the  
safe operation of the equipment. 
Hot Work Permit 
The BP Amoco Naperville Complex has a hot work permit program whic 
h details those areas which  
require a permit and those areas for which a permit is not required.  A permit is required in process areas 
for all cutting, welding, spark producing equipment, etc.  The procedure includes accountability and  
responsibility for authorizing and issuing the hot work permit, display of the permit at the site of the hot 
work until the work is completed, site inspection, designation of appropriate precautions to be taken with  
the hot work, and assignment of a fire watch where appropriate. 
Management of Change 
The BP Amoco Naperville Complex has a  system to manage changes to the 300 Tank Farm.   
This system requires that changes to items such as process equipment, chemicals, technology  
(including process operating conditions), procedures, and other changes be properly reviewed  
and authorized before being implemented.  Changes are reviewed to (1) ensure that adequate controls  
are in place to manage any new hazards and (2) verify that existing controls have 
not been compromised  
by the change.  Affected chemical hazard information and equipment information, as well as procedures, 
are updated to incorporate these changes.  In addition, operating and maintenance personnel are 
provided any necessary training on the change.  The system helps to ensure that all documentation is  
updated and training completed prior to the commissioning of the change. 
Incident Investigation 
The BP Amoco Naperville Complex promptly investigates all incidents that resulted in, or reasonably  
could have resulted in a fire/explosion, toxic gas release, major property damage, environmental loss, or  
personal injury.   The goal of each investigation is to determine the facts and develop corrective actions  
to prevent a recurrence of the incident or a similar incident.  The investigation team documents its  
findings, develops recommendations to prevent a recurrence, and forwards these results to management 
for resolution.  Corrective actions taken in response to th 
e investigation team's findings and  
recommendations are tracked until they are complete.  The final resolution of each finding or  
recommendation is documented, and the investigation results are reviewed with all employees (including  
contractors) who could be affected by the findings.  Incident investigation reports are retained for at least  
5 years, so that the reports can be reviewed during future PHAs and PHA revalidations.  
Compliance Audits 
To help ensure that the accident prevention program is functioning properly at the 300 Tank Farm, the  
BP Amoco Naperville Complex periodically conducts an audit. Compliance audits are conducted at least 
every 3 years.  Both hourly and management personnel participate as audit team members.  The audit  
team develops findings that are forwarded to management for resolution.  Corrective actions taken in 
response to the audit team's findings are tracked until they are complete.  The final resolution of each  
finding is documented, and the two 
most recent audit reports along with the resolution of findings are  
The processes at the BP Amoco Naperville Complex have hazards that must be managed to ensure  
continued safe operation.  The accident prevention program summarized previously is applied to all  
Program 3 EPA RMP covered processes at the BP Amoco Naperville Complex, currently only the 300  
Tank Farm.  Collectively, these prevention program activities help prevent potential accident scenarios 
that could be caused by equipment failures and human errors. 
In addition to the accident prevention program activities, the BP Amoco Naperville Complex has process 
safety features on many units to help (1) contain/control a release, (2) quickly detect a release, and  
(3) reduce the consequences of a release.  The following types of safety features are used in the 300  
Tank Farm.  
Release Detection 
1. Hydrocarbon detectors with alarm. 
Release Containment/Control 
1. Valves to per 
mit isolation of the process (manual or automated). 
2. Curbing or diking to contain liquid releases 
3. Redundant equipment and instrumentation (i.e. uninterruptible power supply for process control  
    system, backup firewater pump) 
4. Atmospheric relief devices 
Release Mitigation 
1. Fire suppression and extinguishing systems  
2. Deluge systems for specific equipment 
3. Trained emergency response personnel 
4. Personal protective equipment (e.g., protective clothing, self-contained breathing apparatus) 
The BP Amoco Naperville Complex maintains a written emergency response program, which is in place 
to protect worker and public safety as well as the environment.  The program includes  procedures for 
responding to a release of a regulated substance, including the possibility of a fire or explosion if a 
flammable substance is accidentally released.  The procedures address all aspects of emergency 
response, including proper first-aid and medical  
treatment for exposures, evacuation plans and 
accounting for personnel after an evacuation, notification of local emergency response agencies and the 
public if a release occurs, and post incident cleanup and decontamination requirements.  In addition, the 
BP Amoco Naperville Complex has procedures that address maintenance, inspection, and testing of  
emergency response equipment, as well as instructions that address the use of emergency response 
equipment.  Employees receive training in these procedures as necessary to perform their specific  
emergency response duties.  The emergency response program is updated as necessary. 
The overall emergency response program for the BP Amoco Naperville Complex is coordinated with the 
Naperville Fire Department.  This coordination includes periodic training and exercises with local  
emergency response officials. The BP Amoco Naperville Complex has around-the-clock communications 
capability with the Naperville Fire Department.  This provides a mean 
s of notifying the public of an  
The BP Amoco Naperville Complex is committed to the safety of its employees and the surrounding 
community.  In particular, the safe operation of the 300 Tank Farm is enhanced through continuous 
improvement.  For example, through internal audits and employee participation, safety items are  
regularly identified, evaluated and implemented as appropriate.  At the time of this writing, the 300 Tank 
Farm is in the process of implementing safety items identified during the last PSM audit.
