Term Defi nition Unity<br />

Property damaging<br />

accidents<br />

Quantity of recovered<br />

materials<br />

Refers to the total number of accidents causing damage to material goods, namely, assets, equipment, product,<br />

productivity, stoppage of production, fi nes for non-compliance with legislation or expenses of another nature,<br />

related to the accident or the person involved in the accident.<br />

Corresponds to the quantity of materials sent for recycling, such as scrap metal, packaging, paper, plastic and<br />

used oil. The Lubricants Plant is not included.<br />

Recovered Sulphur Represents in terms of mass the sulphur recovered in sulphur recovery units.<br />

This value is determined based on the refi nery mass balances, according to the load of H 2 S in the units and its<br />

purifi cation effi ciency.<br />

Recovered sulphur per<br />

load processed<br />

This is provided by the ratio between recovered sulphur, accounted for as described in the contents of<br />

“Recovered sulphur”, and the load processed.<br />

Recycled water Represents the quantity of treated water in the WWTP of Refi nery that is reuse in the water fi re network and in<br />

the service water network.<br />

RFO Consumption Consumption of Combustible Process Waste (Fuel-oil for internal consumption), for burning in LCP´s and process<br />

furnaces.<br />

Number of accidents<br />

Severity rate Number of total days lost per Number of Lost workdays injuries Number of total days<br />

lost/ number of lost<br />

workdays injuries<br />

SO 2 emissions This indicator represents the sulphur dioxide emissions arising from RFO combustion LCP´s and in process<br />

furnaces, in the AP and in the Claus Unit. The combustion emissions are calculated using the following formula:<br />

SO 2 Emissions per level of<br />

activity<br />

SO 2 = SO 2 RFO (t) = Consumption RFO (t) x % S RFO x 0,02<br />

% S RFO represents the level of Sulphur in the RFO (See “Sulphur content in the RFO”). Emissions of SO 2 from the<br />

Fuel Gas and Natural Gas are not considered as the level of Sulphur is very close to zero.<br />

Beginning April 1 st , for fi xed sources with continuous monitoring, the calculation of emissions switched to<br />

being conducted by the Centralised Environmental Information System (SIAC - Sistema Informação Ambiental<br />

Centralizada).<br />

Means the ratio between SO 2 emissions, accounted for according to the contents of “SO 2 Emissions” and the<br />

treated load.<br />

SO 2 ”bubble” Represents the concentration of sulphur oxides in the form of sulphur dioxide, a virtual stack, weighing the<br />

various fl ow rates and concentrations of different sources, as well as their sulphur content. The formula was<br />

approved by the Portuguese Agency for the Environment, and excludes emissions from the Claus unit and<br />

Flares.<br />

Sulphur content in the<br />

RFO<br />

Means the percentage value of sulphur content in RFO. This value is determined in the laboratory, through<br />

weekly analyses on compound samples, the annual value constituting a weighted average of the mean<br />

monthly values.<br />

Total Iron Represents the concentration of Iron in wastewater in accordance with the laboratory analyses conducted in<br />

the Refi nery Laboratory.<br />

Total Suspended Solids Corresponds to the concentration of Suspended Solids in the wastewater, in accordance with the laboratory<br />

analyses conducted in the Refi nery Laboratory.<br />

Wastewater<br />

per level of activity<br />

Wastewater<br />

produced<br />

Waste produced considered<br />

solid urban waste<br />

Water consumption per level<br />

of activity<br />

Means the ratio between wastewater produced, accounted for according to the contents of “Wastewater<br />

produced” and the load processed.<br />

Involves the volume of wastewater produced. m 3<br />

Means the quantity of domestic or similar waste produced, due to its nature or composition ton<br />

Represents the consumption of process water in the plant (captured from the Ave River), as well as water for<br />

human consumption from the <strong>Matosinhos</strong> Municipal Water and Sanitation Service<br />
