Overview
1. NORM (Naturally Occurring Radioactive Material)
2. Maritime bulk shipping
3. Chemical regulation
4. Way forward

Regulations: the new paradigm
SAICM1
REACH2
GHS3
Global initiatives drive regulatory growth
• Hazard based
• Risk based
• Focus on high tonnage substances
1. SAICM: strategic approach to international chemicals management
2. REACH: Registration, Evaluation & Authorization of chemicals
3. GHS: Globally Harmonized System of classification & labelling

Why are regulations increasing?
Accidents and disastersNew technologies
= uncertainty (e.g. nanos)
Political motivation (green agenda)
NGO / consumer group pressure
Too many chemicals…

Naturally Occurring Radioactive Materials (NORM)
The zircon industry needs to anticipate the threats and manage the impact on:-
✓ Production (worker and community exposure)
✓ Transport (including cross-border)
✓ Recycling and waste
FACT: The radioactive nature of zircon has not changed, but the way in which radioactivity is viewed has
FACT: The levels at which a substance is classified as ‘radioactive’ have progressively reduced

Radiation is regulated worldwide
• IAEA – the major reference worldwide
• Local regulations may adopt the IAEA guidelines
• Europe: EURATOM 2013 - effective early 2018
For the first time, ‘Zircon and zirconium’ included in the Annex list of industrial sectors involving NORM…
… data are needed
• ZIA survey of EU-based zircon milling operations

Zircon milling survey - traffic light summary
STORAGEStrict control of access to storage area - for essential access only
PROCESSINGFloor sweeping to be avoided in favour of vacuuming.Look to measure zircon levels in stacks/chimneys
WASTE MGTMaximise recycling of spillage and dust collection in air cleaning equipment.Develop arrangements with landfill operators
H&S
Introduce formal worker Radiation Protection ProgramRisk assessment of operations Use radiation badges at high(er) risk locationsMeasure exposure to public around the site
FINAL PRODUCTEnsure paper sacks are protected and secure on palletIntroduce emergency procedure for road/rail transport

NORM- main messages
1. Zircon industry is mature and experienced in handing the demands of NORM.
2. Zircon / zirconia is on the regulator’s radar, albeit at a low priority
3. Latest exposure data are always needed
![Page 10: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/10.jpg)

Maritime shipping codes:
• Driven by internationally-agreed codes managed by the IMO*- MARPOL recently updated by alignment with GHS
• Others updated as evidence arises on cargo characteristics that may affect safety of a vessel and/or of the crew.
• Know your cargo – data needed*IMO – International Maritime Organization (United Nations)

Maritime transport: IMSBC
Bulk cargoes fall into three groups:
• Group A – cargoes that may liquefy (ilmenite is group A)• Group B – cargoes with a hazard that could endanger vessel or crew• Group C – other cargoes that can still be hazardous.
A
B
C
Zircon is group C
![Page 12: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/12.jpg)
12
Other current issues
• Ilmenite: recent Group A cargo (liquefaction) - moisture content to be measured for each cargo.
• Zircon: may need to test to pre-empt an unjustified Group A cargo schedule
• Also, an inaccurate reference to ‘sand’, with the known long-term health effects associated with silica, may mean that others mineral sands are classified as harmful (zircon sand, rutile sand, ilmenite sand…)
• Materials hazardous in bulk: corrosivity to metals tests ongoing – mandatory from Jan 2017

Chemical regulations: the challenges
• Shifting the burden-of-proof (of safe use) to industry
• Precautionary principle - a driver for regulatory decisions
• Lack of robust, admissible data
• Hazard, rather than risk, used to prioritise chemicals for regulatory scrutiny…
…so what?
![Page 14: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/14.jpg)

TiO2 classification proposal
Why is the zircon industry interested?
• Zircon with >0.1% TiO2 carries the same classification.
classification GHSCat 1B carcinogen
![Page 15: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/15.jpg)
15
Also…
• USA Occupational Safety and Health Administration(US-OSHA) amended standards for occupationalexposure to respirable crystalline silica, reducingthe permissible exposure limit (PEL) to 50μg/m3.
• Of more concern, European authorities areconsidering a proposal to classify crystalline silicaas a carcinogen
![Page 16: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/16.jpg)

Other REACH-like derivatives
• Asia (S. Korea, China, Japan): updating regulations in sympathy with REACH
• Cataloguing, leading to prioritisation of chemical registrations e.g. S Korea
• REACH-like, but some important differences do exist (e.g. annual reporting in South Korea)
• GHS* is not (yet) harmonised. Scientifically unjustified classifications exist and these need to be addressed with reliable data
*GHS- Globally Harmonised System for classification and labelling
![Page 17: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/17.jpg)
17
Conclusions:
• NORM – understood and well managed in the industry. Keep ahead of the next regulatory cycle
• Maritime: needs close monitoring and appropriate lobbying at local maritime authorities.
• Chemical: vigilance needed. Over precautionary approach and unjustified classifications can catch industry unawares
REGULATORY COMPLIANCE = BUSINESS CONTINUITY
![Page 18: Kevin Harlow - Zircon Industry Association](https://reader031.vdocuments.site/reader031/viewer/2022012317/58d1593b1a28ab41128b67ad/html5/thumbnails/18.jpg)

Final takeaway
• Our industry is facing a dynamic, rapidly changing and more demanding system of regulation
• Data, data, data..!
The regulatory burden will grow
