Particulates
RMMs are primarily aimed at controlling emissions of particulates at the most significant emission
points to atmosphere from sources within the manufacturing process where airborne particulates
can be created.

- particulate raw materials are delivered in bulk tankers and discharged to closed silos
- particulate raw materials are delivered in closed packaging (IBCs, drums, boxes, sacks)
- closed transfers of particulates from storage to production equipment (e.g. metered piped or
pumped additions) is used
- no extraction is used on closed production equipment, when adding and incorporating particulate
raw materials
- use of semi-closed production vessels with extraction to atmosphere are used to maintain
workplace airborne particulate concentrations below respective OELs
- cyclone and bag filters, connected to (often multiple) emission sources, are used to control
emissions from manufacturing plant
- particulate wastes are stored in closed containers.

Bag and cyclone filters are typically rated at 99% efficient.

Narrative Description of, and justification for, specific ERC
Description: The manufacture of powder coatings and inks is a multi-stage batch process. The process is arranged to maximise the efficiency of use of input raw materials,
through the highest conversion into formulated products. Process losses are reduced to the absolute minimum, through use of general and manufacturing plant extraction to
maintain workplace concentrations of airborne VOCs and particulates below respective OELs; and through use of closed or covered manufacturing equipment, wherever
possible, to minimise evaporative losses of VOCs. The composition of products and the overall process are such that there are no discharges of raw materials or products to
waste-water or to soil from the manufacturing plant.
Justification: The overall high efficiency of the coatings and inks manufacturing process is reflected in the low emission factors identified in independent assessments, such as
that carried out by the UK’s Environment Protection Agency, as part of the development of an Emission Scenarios Document for the OECD.

Communication in eSDS
The REACH registrant establishes a set of standard conditions of safe use for a substance in the formulation of a coating or ink by adopting the conditions specified in this
SPERC and recommending a Required Removal Efficiency (RRE) for adequate risk reduction. This may include the removal efficiency of municipal sewage treatment plant
(RESTP,SPERC), and the efficiency of an on-site emission reduction (REER,SPERC). This information is documented in the Chemical Safety Report and communicated in the
extended Safety Data Sheet.
All other parameters underlying a substance exposure scenario based on this SPERC are implicitly referred to via the reference to this SPERC.
Scaling (emissions to waste water only)
The formulators of organic solvent and water borne coatings and inks are responsible for evaluating the compliance of their specific situations with the registrant’s information.
To that end, the users need to know their site-specific substance use rate (MSite) and days emitting (TEmission,Site), onsite and offsite emission controls and subsequent total
substance emission reduction efficiency (RETotal,Site = 1 – [(1 – REOnsite,Site) x (1 – REOffsite,Site)]), sewage treatment plant effluent flow rate (GEffluent, Site) and receiving water
dilution factor (qSite). Adequate control of risk exists if the following relevant expression holds true:
for risk driven by wastewater treatment plant microbes
[MSPERC x (1 – RETotal,SPERC )] / GEffluent,SPERC [MSite x (1 – RETotal;, Site)] / GEffluent,Site
for risk driven by freshwater/freshwater sediments, marine water/marine water sediments
[MSPERC x (1 – RETotal,SPERC )] / (GEffluent,SPERC x qSPERC ) [MSite x (1 – RETotal, Site)] / (GEffluent,Site x qSite)
for risk driven by secondary poisoning (freshwater fish/marine top predator) or indirect exposure to humans (oral)
[MSPERC x TEmission,SPERC x (1 – RETotal,SPERC )] / (GEffluent,SPERC x qSperc ) [MSite x TEmission,Site x (1 – RETotal, Site)] / (GEffluent,SPERC x qSite)
It is simpler and thus may be preferable to some users to compare MSite with MSafe (the maximum tonnage that can be safely used, within the prescribed operating conditions,
OC SPERC and RMM, RETotal,SPERC ). Adequate control of risk exists if the following conditions are met [RETotal ,Site RETotal,SPERC, GEffluent,Site, GEffluent,SPERC and qSite
qSperc] and MSafe MSite.
Local amount used, emission days per year, receiving water flow rate (or dilution factor), sewage treatment plant effluent flow rate, and risk management measure removal
efficiency are the adjustable parameters for emission assessment. These parameters can be refined using site-specific information, which often is obtainable with limited effort
and expertise. Adjusting the assessment by refining these parameters is referred to as scaling. Scaling is applied to evaluate compliance of a specific use with a generic
Exposure Scenario. For that reason, site parameter values which deviate from the default values need to reflect the actual situation. This may have to be justified on demand.
The release factors are an additional set of adjustable parameters; however, refining the default values requires significant justification and, thus, is beyond the boundary
conditions defined in the SPERC Factsheet. For that reason, release factor refinements do not constitute a SPERC-based assessment and must be considered an element of
downstream user chemical safety assessment.
