Condition of Approval #35 .A. : Noise Calculations
This condition requires Shell Oil Company to submit noise level
calculations which demonstrate that the project units will comply
with the noise performance standard of 77 dBA when measured five
feet above the ground and 100 feet from the equipment. This noise
performance standard assures that the project will not increase
noise levels at the nearby residences.
Shell Oil Company submitted noise calculations for the Lube
Hydrotreater #2 . As required by the land use permit, the report
was prepared by an individual who is a member of the Institute of
Noise Control Engineering and who has at least five years experi-
ence in noise control engineering (27 years experience cited) .
Condition of Approval #22 : Hazard and Operability Study
This condition requires Shell Oil to prepare a Hazard and Oper-
ability Study and accident consequence analysis for all elements of
the Clean Fuels Project with the exception of the office building,
the control rooms and the maintenance/warehouse buildings.
Shell Oil Company completed the required study for the Boiler
Feedwater Treater, the Cooling Water Tower, the Oil/Water Separa-
tors, the process water tanks and the additives system. This
information was evaluated by the Risk Management and Prevention
Program Team of the Health Services Department. Their review
included a detailed examination of the hazard analyses and off-site
consequences as well as scrutiny of all the programs or aspects of
the Company (e.g. , operating procedures, preventive maintenance
programs and _operator training) which are designed to prevent or
mitigate accidents or process anomalies. The review included
document assessments, management and operations personnel inter-
views and process "walk throughs" to verify documentation. The
Health Services Department identified additional safety equipment
which Shell must install. Consistent with the land use permit, the
Health Services Department will conduct follow-up field inspections
to ensure that all recommendations have been implemented.

SUBJ: CONSENT ITEM FOR SHELL REFINERY CLEAN FUELS PROJECT
CONDITION #22
Executive Summary:
The Contra Costa County Health Services Department (CCCHSD) Hazardous Materials Risk
Management and Prevention Program team has completed the Clean Fuels reviews for Shell
Refinery's utility areas scheduled for start-up on April 1, 1995.
Several utilities will be required to support the operation of the new process units. These will
include cooling water, boiler feedwater, aqueous ammonia additives for selective catalytic
reduction, and process water facilities.
Cooling Water Tower - Cooling water will be used to absorb heat, via heat exchangers from
the process units. The heat absorbed by the water will be removed in an open recirculating
tower, where warm water is cooled by contact with ambient air. The recirculating water is
subject to biological growth which can cause fouling in the exchangers. Small concentrations
of treatment chemicals will be added to the recirculating water to help prevent corrosion,
scaling and microbiological fouling.
Boiler Feedwater Treatment - Boiler feedwater will require treatment prior to being utilized
at the boilers. Treatment will consist of several sequential steps that remove suspended solids,
dissolved solids, hardness and dissolved oxygen. Suspended solids will be removed in
clarifiers with the aid of polymeric material. Remaining small particles will be removed by
filtration. Dissolved solids will be removed by reverse osmosis which forces the water through
a semipermeable membrane. Acid and sulfite will be added as treatment chemicals to prevent.
degradation of the membrane from scaling or biological growth. Hardness (calcium and
magnesium) will be removed by resin softening.

CONTRA COSTA COUNTY
REVIEW OF CLEAN FUELS SYSTEM
SHELL OIL COMPANY,MARTINEZ MANUFACTURING COMPLEX
PURPOSE OF REVIEW
As a condition for approval of Land Use Permit#2009-92 (Shell Oil Company Clean Fuels
Project), Board Order Condition#22, Contra Costa County Health Services Department
(CCCHSD)Hazardous Materials Risk Management and Prevention Program team was requested
to review and evaluate the Clean Fuels systems for Shell Oil Company, Martinez Manufacturing
Complex.
SCOPE OF REVIEW
The review of the Clean Fuels System at the Shell Oil Company includes a detailed examination of
the hazard analyses and off-site consequences,as well as scrutiny of all of the programs or aspects
of the business which are designed to prevent or mitigate accidents or process anomalies. For
example,the design safety of new equipment, operating procedures,preventive maintenance
programs,operator training,emergency operating procedures as well as emergency response
planning,and audit procedures to ensure that these programs are being executed as planned will be
reviewed and evaluated for efficacy.
The review process occurs primarily on-site at the facility. The review includes document
assessments,management and operations personnel interviews,Hazard and Operability Studies
(HazOps)question and answer sessions, and process"walk throughs"to verify documentation,
safeguards (process control and alarms, shutdowns,monitors, checklists,procedures, etc.)and
recommendations from the HazOps.
CONCLUSION
At the conclusion of the review,CCCHSD staff will provide the facility with a list of findings,
concerns, and outstanding questions. The facility will be required to clarify or respond to each
item. CCCHSD will then issue a report to the Zoning Administrator,delineating the necessary and
recommended corrections to the procedures, the documentation,and the facility.
