# The Environmental Authorisations (Scotland) Regulations 2018, Paragraph 17: Solvent management plans: interpretation


For the purposes of this Part—
(a) In relation to inputs of organic solvents (I)—
“I1” refers to the quantity of organic solvents or their quantity in mixtures purchased which are used as input into the process in the time frame over which the mass balance is being calculated,
“I2” refers to the quantity of organic solvents or their quantity in mixtures recovered and reused as solvent input into the process. The recycled solvent is counted every time it is used to carry out the activity,
(b)In relation to outputs of organic solvents (O)—
“O1” refers to emissions in waste gases,
“O2” refers to organic solvents lost in water, taking into account wastewater treatment when calculating O5,
“O3” refers to the quantity of organic solvents which remains as contamination or residue in products output from the process,
“O4” refers to uncaptured emissions of organic solvents into air. This includes the general ventilation of rooms, where air is released to the outside environment via windows, doors, vents and similar openings,
“O5” refers to organic solvents and/or organic compounds lost due to chemical or physical reactions (including those which are destroyed, by incineration or other waste gas or wastewater treatments, or captured, as long as they are not counted under O6, O7 or O8),
“O6” refers to organic solvents contained in collected waste,
“O7” refers to organic solvents, or organic solvents contained in mixtures, which are sold or are intended to be sold as a commercially valuable product,
“O8” refers to organic solvents contained in mixtures recovered for reuse but not as input into the process, as long as not counted under O7,
“O9” refers to organic solvents released in other ways.
