Enviromental management system
What is ISO 14000? The ISO 14000 family includes most notably the ISO 14001 standard, which
represents the core set of standards used by organizations for designing and
implementing an effective Environmental Management System (EMS).
ISO 14001 sets out the criteria for an Environmental Management System
(EMS).
It does not state requirements for environmental performance, but maps out a
framework that a company or organization can follow to set up an effective EMS.
It can be used by any organization that wants to improve resource efficiency,
reduce waste, and drive down costs.
Using ISO 14001 can provide assurance to company management and
employees as well as external stakeholders that environmental impact is being
measured and improved.
13
Enviromental management system
What is EMAS?
EMAS (Eco-Management and Audit Scheme) is a voluntary certificatione created
by the European Community to evaluate and improve the environmental
performance of a company.
All information about the environmental management of the company, are
provided to the public and to the other stakeholders.
In 2010, the latest EMAS Regulation (EMAS III) entered into force; the scheme
is now globally applicable, and includes key performance indicators and a range
of further improvements.
Objective of EMAS is to promote the rispect of all environmental aspects.
This action is based not only on the limits imposed by law, which remains an
obligation owed, but on the continuous improvement of environmental
performance, the creation of a new relationship with the institutions and the
public and the active participation of employees.
14
Enviromental management system
What is OHSAS 18001?
It is an internationally applied British Standard for occupational health and safety
management systems. It exists to help all kinds of organizations put in place
demonstrably sound occupational health and safety performance. It is a widely
recognized and popular occupational health and safety management system.
BS OHSAS 18001 specifies requirements for an OH&S management system to
help an organization develop and implement a policy and objectives, which take
into account legal requirements and information about OH&S risks. It applies to
all types and sizes of organizations and accommodates diverse geographical,
cultural and social conditions.
15
Enviromental management system CEMS
Continuous Emission Monitoring Systems (CEMS)
CEMS are required to be installed in facilities specified by ISPRA (Italian
Ministry of the environment).
The CEMS are used to continuously monitor the effectiveness of air pollution
control techniques and to determine if source control requirements are being
met. It is required for continuously monitoring compliance with a specific
pollutant emission limit or to monitor compliance with source and pollution
control device operating limits.
Continuous monitoring system is defined as the total equipment (sample
interface, analyzer, and data recording) required for determining emissions
and/or operating parameters.
The CEMS shall continuously monitor and record the concentration of gaseous
pollutant emissions on a wet or dry basis discharged into the atmosphere
consisting of subsystems for sample extraction, conditioning, detection,
analysis, and data recording/processing.
16
The refinery CEMS provides to monitoring the emission points “continuously
monitored” and “not continuously monitored”.
Processing criteria used by the emission monitoring system for defining the
overall refinery data involves:
• extent of contributions from the emission points;
• processing of data acquired by the system for checking compliance with the
limits.
Enviromental management system CEMS
17
Emission points with continuous monitoring
The continuous measurement system for emissions from 10 stacks (which
constitute about 90% of total emissions) provides for the acquisition of the
following parameters:
• Sulfur Dioxide (SO2)
• Nitrogen oxide (NOx)
• Carbon Monoxide (CO)
• Oxygen (O2)
• Total Organic Compound (TOC)
• particulate matter
• Flue Gas Temperature / Pressure / Flow
The PC system provides the measurement of concentrations coming from
monitoring booths for NOx, SO2, CO and PM; the flue gas flow measurement
is related to oxygen prescribed for the emission point (3% or 15%).

Emission points not continuously monitored (estimated values)
The estimation procedures used for issuing points without continuous
monitoring system are:
• stechiometric calculation of SO2 (depending on the quality and quantity of
fuel used)
• estimation of emission values of NOx application emission factors;
• estimation of emission of CO through the application of emission factors;
• estimation of particulate emission values by applying emission factors;
• estimation of flue flow refers to the oxygen content laid down by
stechiometric calculations.
The estimated concentration data are expressed in mg/Nmc and are referred
to the oxygen content of the reference (3% or 15%).
The values (continuous measurement + estimated values) are immediately
available to calculate total emissions (Refinery “Bubble”).

22
Enviromental management system CEMS
In accordance with the AIA, emission values are calculated as weighted ratio
between the sum of the masses of pollutants emitted and the sum of the
volumes of waste gas of refinery.
A “CEMS Manual” has been prepared to specify the requirements for CEMS
operation, reporting, and quality assurance/quality control (QA/QC).
Performance Specifications are used for evaluating the acceptability of the
CEMS at the time of or soon after installation and whenever specified in the
regulations.
Quality assurance procedures are used to evaluate the effectiveness of quality
control (QC) and quality assurance (QA) procedures and the quality of data
produced by any CEMS that is used for determining compliance with the
emission standards on a continuous basis as specified in the applicable
regulation.

Enviromental management system Air quality monitoring
Air quality monitoring
The control of air quality (Immissions) is carried out through a network of
detection stations located in the area of interest of the refinery as part of the
monitoring network of ARPA Lombardia. These monitoring stations, managed
directly by ARPA Lombardia, are part of a wider system, composed of about 190
stations located throughout the region.
The network is composed of 5
monitoring stations located in the
towns of
• Scaldasole,
• Ferrera,
• Galliavola,
• Mezzana Bigli/Casoni
Sannazzaro
25
Enviromental management system Air quality monitoring
In Sannazzaro Refinery there is also a meteorological station (located inside the
refinery).
The meteorological station records the following variables:
• wind speed and direction;
• temperature;
• relative humidity;
• temperature;
• pressure;
• precipitation;
• solar radiation
26
Enviromental management system Air quality monitoring
Daily ARPA transmits to the refinery a bulletin on air quality around the territory
where the refinery insists, on the basis of the data collected the previous day.
The intervention of a third party institution ensures the independence of the
results of the activities of control and monitoring.
The air quality in the area of interest of the Refinery is good: in the last few
years, for the totality of the pollutants studied, the measured values are well
below the limits established by law.
27
Energy Management System
Sannazzaro refinery obtained and maintain EMS certification since
last June 2012 as for Internation Standard :
ISO 50001
This means that the Refinery works under an Energy Management
System, it keeps monitoring and controlling for each energy source
utilization and search for continuous efficiency improvement.
