Storage and handling modes Emission control measuresBAT examples
Slide 3
Scope
• Solids, liquids and liquefied gases
• Storage modes
• Transfer and handling techniques
• Process control equipment
• Abatement techniques
• Safety
This is a horizontal BREF
Slide 4
Slide 5
Storage techniques Liquids and liquefied gases
Chapter 3 describes:
• 11 different tank types + equipment
• Storage of containers
• Basins and lagoons
• Caverns
• Floating storage
and identifies their main emission sources
Slide 6
Chapter 3 describes:
• Piping systems
• Pumps and compressors
• Flanges and valves
Transfer & handling techniquesLiquids and liquefied gases
Slide 7
Emission Control Measures (ECM) Liquids and liquefied gases
Chapter 4 describes ECM to prevent and/or reduce emissions:
> 90 ECM for storage
> 30 ECM for transfer and handling
Slide 8
Emission Control Measures (ECM) Liquids and liquefied gases
ECM for a fixed roof tank described in Chapter 4:
• Management tools, design, inspections
• Techniques for reducing emissions to air:
tank colour internal floating roofs vapour balancing/treatment
Slide 9
Emission Control Measures (ECM) Liquids and liquefied gases
ECM for a fixed roof tank described in Chapter 4:
• Techniques for reducing emissions to soil:
corrosion and erosion double tank bottoms double wall tanks containment
Slide 10
ECM assessment methodology Liquids and liquefied gases
A scoring system to determine the best performing
ECM, or combination of ECM, for each specific
storage mode. The scores relate to:
• The emission reduction potential of the ECM being considered
• The ‘operational features’ of the ECM• The cost to install and to operate the ECM
Slide 11
ECM assessment methodology Liquids and liquefied gases
Conclusion of the 2nd TWG meeting:
• This methodology is not BAT• This methodology is mentioned in the
introduction of Chapter 5• BAT, as detailed as possible, are concluded
Slide 12
BAT on storage tanks Liquids and liquefied gases
Example: BAT identified for all tanks are on:
• Inspection and maintenance• Tank colour• Monitoring of VOC• Risk-based approach to emissions to soil• Containment; bunds, double wall tanks• Fire protection/fire-fighting equipment
Slide 13
BAT on storage tanks Liquids and liquefied gases
Example: BAT for a fixed roof tank
For volatile substances which are toxic, very toxic or CMR (carcinogenic, mutagenic and reproductive toxic) categories 1 and 2: • BAT is to apply a vapour treatment installation
For other substances:• BAT is to apply a vapour treatment installation,
or to install an internal floating roof
BAT associated emission levels are given
Slide 14
BAT on storage tanks Liquids and liquefied gases
Split views are reported on the:
1. Monitoring of VOC
2. Vapour treatment of certain substances
3. ECM assessment methodology

Solids
Slide 17
Storage techniquesSolids
Chapter 3 describes:
• Open storage
• Sacks and bulk bags
• Silos and bunkers
• Packaged dangerous solids
Slide 18
Transfer & handling techniques Solids
Chapter 3 describes:
• The construction and reclaiming of heaps
• Loading and unloading devices: grabs hoppers fill pipes several types of conveyors
Slide 19
Emission Control Measures (ECM) Solids
Chapter 4 describes ECM to prevent and/or reduce dust emissions:
~ 20 ECM for storage of solids
~ 40 ECM for transfer and handling
Slide 20
Emission Control Measures (ECM) Solids
ECM for open storage described in Chapter 4:
• Sheds or roofs
• Large volume silos + dust filters
• Covering of the surfaces
• Wind protection methods
• Spraying of water with or without additives
Slide 21
Emission Control Measures (ECM) Solids
ECM for handling described in Chapter 4:
• Weather conditions• Roads with hard surfaces
• Cleaning of roads and tyres
• Closed conveyor systems
• Spraying of water with or without additives
Slide 22
BAT on storage of solids
BAT for open storage is:• Closed storage + dust abatement
BAT on short term open storage:• Moistening with water or dust binding substances• Covering the surface, e.g. with tarpaulins
BAT on long term open storage:• Moistening with dust binding substances• Covering the surface, e.g. with tarpaulins• Solidification or grassing over of the surface
Slide 23
BAT on handling of solids
Examples of BAT:
• Applying continuous transport modes• Using roads with hard surfaces + cleaning• Moistening drift sensitive, wettable products• Minimising speed of descent and free fall height,
e.g. using height adjustable cascade tubes
Slide 24
BAT on handling of solids
BAT example on conveyors
• For non drift sensitive and moderately drift sensitive, wettable products, BAT is to apply an open conveyor
• For other products and for new situations, BAT is to apply a closed conveyor
Slide 25
BAT on solids
There are no split views on the
BAT conclusions on solids.
Slide 26
Conclusions
• The TWG reached a high degree of consensus on the BREF document and on the BAT conclusions
• Five split views were reported in the liquids and liquefied gases part of the document; no split views on solids
• A useful document for the permitwriter
• The Province of Zeeland is offering you practical help in your permitwriting processes
