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
