Executive Summary


EPA's Accidental Release Prevention Rule, which is authorized
under 112(R) of the Clean Air Act (CAA), requires that
facilities that have covered processes establish Risk
Management Programs to reduce the risks of accidental release
of toxic or flammable materials and establish emergency
response procedures in the event of an accident. This Risk
Management Plan summarizes the efforts that this company has
undertaken to establish a Risk Management Program.

Anhydrous ammonia is the only chemical used at the AES Hawaii
facility that is above the RMP threshold amount. The onsite
maximum storage quantity of the liquid anhydrous ammonia tank
at the AES Hawaii plant is 109,000 pounds, which is above the
10,000 pound RMP applicability threshold. The AES Hawaii plant
does not use any other chemicals or flammable materials in
excess of threshold quantities covered by RMP requirements.

A management system will be in place at the facility to
oversee implementation of the facility's Risk Management
Program. This management system is considered one of the most
important elements of this facility's Risk Management Program,
as its goal is to ensure that lines of authority and
responsibility are clearly defined, helping to ensure that all
elements of the Risk Management Program are implemented. At
the AES Hawaii Facility, the person who has the overall
responsibility for the Risk Management Program is the
environmental coordinator.

The facility also participates in emergency response
activities with the Campbell Local Emergency Action Network
(CLEAN). CLEAN has developed an Emergency Management Plan that
provides supplemental guidance and information to emergency
response personnel, local residents, and business based on the
specific operations in and around Campbell Industrial Park
(CIP). The plan addresses emergency planning, public health
and safety

The AES Hawaii facility generates steam and electricity at 91-
086 Kaomi Loop, Hawaii 96707. The Plant is located near
Barber's Point, within the area known as Campbell Industrial
Park, which is on the Island of Oahu about 30 miles west of
Honolulu. Electricity generated by the facility is supplied to
Hawaiian Electric Company, and steam is sold to the nearby
Chevron USA oil refinery. The plant has two Circulating Fluid
Bed (CFB) coal-fired boilers and one steam turbine. The CFB
boilers use a clean coal technology that minimizes emissions
of sulfur dioxide, nitrogen oxides. The boilers use limestone
that reacts with the sulfur in the coal to reduce sulfur
dioxide emissions. The nitrogen oxides emissions are reduced
by two factors: the relatively low boiler operating
temperatures and the addition of anhydrous ammonia to the
boiler flue gas that reacts with the nitrogen oxides to
produce harmless nitrogen gas and water vapor.

Ammonia safety considerations have been incorporated into the
construction of the ammonia system. The ammonia tank is
secured to the ground and has cathodic protection. The tank
has relief valves at the top of the tank. Thus,
overpressurization of the tank would primarily involve the
venting of gas in the upper part of the tank. The vapor lines
from the tank to the boiler area are buried to reduce
potential releases from this piping. Loading and unloading
valves, the tank and tanker truck are equipped with automatic
shut-off valves in the event that flow through the valves
exceeds design criteria. Therefore, in the event of a loading
hose failure, the flow of ammonia would be automatically
terminated. The facility also has a monitor located in the
ammonia system process area that detects leaks and triggers an

This facility maintains a Prevention Program at the facility
that minimizes the possibility of any accidental r
elease from
the ammonia system. The prevention program incorporates a
mechanical integrity program, regularly scheduled maintenance,
daily visual operational checks of equipment, and employee
training in proper operating procedures and emergency

AES Hawaii has designed a Mechanical Integrity Program for
ammonia in accordance with 29 CFR 1910.119(j). The purpose is
to verify that critical process equipment is designed,
installed, maintained properly, and operates correctly. In
accordance with this program, the ammonia processes and
equipment must be constructed, installed, and maintained in
order to minimize the risk of releases of the highly hazardous
chemicals. The mechanical integrity program at AES Hawaii
includes identifying and categorizing equipment. Inspecting
and testing of instrumentation and documenting maintenance
procedures; training of maintenance personnel; establishing
criteria for acceptable test results; documenting test and
inspection results; and documenting manufacturer information
for equipment and instrumentation.

The facility performs a system integrity check every five
years for the ammonia storage tank and all associated
hoses/lines. The most recent vessel inspection was completed
in 2008. In addition, all emergency relief and excess flow
valves, storage tank isolation valves, flexable connections,
and hoses are scheduled for replacement in 2009. The equipment
is maintained in accordance with manufacturer specifications,
and applicable ANSI, and ASME engineering codes. A
computer database generates work orders to identify when such
maintenance needs to be implemented. Once, each 12-hour
period, operators visually observe the equipment for signs
of potential malfunction. Alarms and interlocks are checked
on a monthly basis.

All new employees, regardless of position, are given a safety
walk of all areas of A
ES Hawaii. This walk through includes
the ammonia system. Special emphasis is placed on the nature
of the anhydrous ammonia and actions of all personnel in case
of an ammonia problem (i.e. leak). All persons hired who are
responsible for operations of the ammonia system are given
full classroom training before they are allowed to work on,
operate or otherwise manipulate or affect the ammonia system.
The classroom course includes detailed instruction on the
ammonia system, including the physical aspects of ammonia,
operating the ammonia system, and casualties involving the
ammonia system. They are trained regarding the hazards and
safety precautions to be observed for the ammonia system. In
addition, annual refresher training is required.

The plant has a current "Disaster and Emergency Plan". All
employees have been trained in the plan, and the plan is
reviewed frequently to verify that it is current with plant
operating practice. The plan contains emergency response
procedures (ERP) which include actions for evaluating the
severity and controlling releases of hazardous materials
including ammonia. A list of the agencies that must be
notified is included in the plan to assure that the public is
properly notified in the event of an emergency.

AES Hawaii has performed a Hazard and Operability (HAZOP)
Analysis that evaluated all potential hazards for the
facility. The HAZOP study was performed according to the
procedures described in "Guidelines for Hazard Evaluation
Procedures; Center for Chemical Process Safety" published by
the American Institute of Chemical Engineers, New York. The
HAZOP was performed by a team of technical experts in the
system's process, engineering, design, operations maintenance,
and safety. The ammonia system was divided into sections or
segments and assigned a node number. Each node was evaluated
for deviations using guide words
such as "no flow", "high
pressure", etc. The cause and consequence of a guide word
applied to a node were evaluated to determine and identify
deviations and/or hazards that can result from application of
a guide word to the node. Each identified consequence was
assigned a relative risk rank based on the severity of the
consequence and anticipated frequency. The team then discussed
corrective actions which were recorded and implemented or are
in the process of being implemented.

AES has implemented these various analyses and training
programs to prevent and prepare for an emergency release. To
date, this facility's Five Year History (and entire history of
the plant) does not include any accidental releases from the
ammonia system which resulted in deaths, injuries, or
significant property damage onsite, or known offsite deaths,
injuries, evacuations, sheltering in-place, property damage,
or environmental damage.
