IAQM Guidance

IAQM Guidance

Dust John Salmon

• “The operational phases of minerals (and some waste) sites share some common features with construction activities; however minerals sites can be significantly larger scale. A qualitative dust assessment for a minerals site would normally be expected to be at least as rigorous as one carried out in accordance with the IAQM construction dust method, reflecting the potential for mineral sites to have a greater impact than construction sites”

(IAQM Guidance 2014)

CONSTRUCTION SITE v QUARRY

Dust John Salmon

Quarry Sites

Predominantly Rural Areas

Often Remote

Stand-offs from Sensitive Property

Landscape Screening

Topographical Screening – Bunds / Quarry Faces

Progressive Extraction – Part Only of Site Worked at any One Time

Planning Control

Planning Inspections

Other Environmental and Legislative Controls

Dust and Planning

Dust John Salmon

• Planning Permissions for a new quarry will contain around 30-50 conditions to control the development.

• Typical Dust Control Condition:

“Operations on the site shall be controlled, and measures taken as

far as practicable, to prevent causing dust in accordance with a scheme for dust control approved in advance by the Mineral Planning Authority which shall include:-

(a) measures for the suppression of dust caused by the moving and storage of soil and overburden, stone and other materials;

(b) dust suppression on haul roads”.

MANAGEMENT TOOLS Sheeting Lorries Washing and Cleaning Lorries Transport Management Especially Limiting Speeds Repair and Use of Wheel Cleaners MONITORING AND TRAINING Visual Monitoring Risk Training Advance Weather Warnings – Be Prepared Staff Must Know What To Do Check and Review Control Measures Regularly RESPONSIVE MANAGEMENT Good Management Practices. Good Housekeeping Selection, Provision and Use of PPE Keeping Plant and Surfaces Clean Mending Potholes and Keeping Roads in Good Repair Closing Down or Changing Operations in Severe Wind Events

National Planning Policy Framework

Dust John Salmon

Minerals Policy:

“23 The National Planning Policy Framework makes it clear that unavoidable dust emissions are controlled, mitigated or removed at source. A dust assessment study should be undertaken by a competent person/organisation with acknowledged experience of undertaking this type of work”

QUARRIES PARTNERSHIP SCHEME DUST INITIATIVE

Dust John Salmon

An alliance of Quarry Operators and Trade Associations working together to increase awareness of the risks associated with the

inhalation of dust in the quarry industry and to promote good control practices.

Focussing upon Respirable Crystalline Silica and workplace dust, improving worker’s knowledge and ultimately bring

about a change in attitudes to workplace dust.

Respirable Crystalline Silica HSE Occupational Health Intervention Strategy 2014

Mineral Products Association Guidance

CONTROL OF RCS Workplace Exposure Limit of 0.1 mg/m3. Provision, Selection and Use of Respiratory Protective Equipment Health Surveillance GOOD CONTROL PRACTICES (COSHH REGULATIONS) Design and Operating Processes Minimise Escape and Spread of Hazardous Substances Education and Training Protective Clothing HOUSEKEEPING Good Management Practices. Keeping Plant and Surfaces Clean and Tidy Maintenance of Plant Cabs, Plant Control Rooms, Mess Rooms Personal Hygiene “Stop Dust Before it Stops You”
