How often are you required by law to measure dust emissions?

The **frequency of dust emission measurements** is determined by your environmental permit, business activities and risk class. Most industrial companies must measure their dust emissions at least once a year, but this can increase to monthly for companies with high emissions. Sectors such as mining, recycling and power stations often face stricter requirements due to their impact on air quality.

What exactly does the law say about dust emission measurements?

Dutch companies must measure their dust emissions in accordance with the **Environmental Management Act** and the Environmental Management Activities Decree. The exact requirements are set out in your environmental permit or in the general regulations, depending on your company’s type and size.

The Activities Decree stipulates that companies must monitor their emissions if they exceed certain threshold values. For particulate matter, this limit is usually around 5 mg/m³ for new installations. Existing installations sometimes have more lenient standards, but must still comply with Best Available Techniques (BAT).

You are also obliged to report your measurements to the provincial authority or the water board. This reporting must usually take place annually, unless your licence stipulates otherwise. If limit values are exceeded, you must take immediate action and report this to the regulatory authority.

It is important to note that the law does not only focus on **emissions monitoring**, but also on the measures you take to limit particulate matter. Prevention is paramount in Dutch environmental legislation.

How often should you measure dust emissions by sector?

The frequency of monitoring varies significantly by sector and depends on your emission level and risk class. Companies in the various industrial sectors each have their own specific requirements.

Sector Typical measurement frequency Comments
Mining Monthly to quarterly Depending on production capacity
Recycling Quarterly to half-yearly More common in mechanical processing
Power stations Continuous monitoring Particularly in the case of biomass and coal
Steel industry Monthly Stricter requirements for blast furnaces
Dry bulk transhipment Half-yearly to annual Seasonal variations

Power stations that burn coal or biomass often have the strictest requirements. Continuous monitoring of particulate emissions is mandatory here, particularly for installations with a thermal capacity exceeding 50 MW.

Recycling companies that carry out mechanical processing (shredding, screening, crushing) usually need to carry out measurements on a quarterly basis. Where only storage and transhipment are involved, this can be reduced to half-yearly.

What factors determine your monitoring frequency?

**Five key factors** determine how often you need to carry out measurements: your emission levels, company size, location, permit conditions and the extent to which your activities are dust-sensitive.

Your **emissions level** is the most important factor. Companies operating close to the limit values must carry out measurements more frequently than those with low emissions. If you regularly remain below 50 per cent of the limit value, you can often apply for a lower measurement frequency.

The **location** is also a factor. Companies in urban areas or near nature reserves are often subject to stricter requirements. This is because the impact on local residents and vulnerable ecosystems is greater.

Your **licence conditions** may differ from the standard rules. Some companies are offered a bespoke approach, for example if they have demonstrably implemented effective dust control solutions.

**Company size** and **risk class** determine whether you fall under the Activities Decree or require a full environmental permit. Large companies (IPPC installations) usually have stricter monitoring requirements than smaller companies.

What happens if you don’t measure enough?

**Fines for inadequate dust emission measurements** can amount to €870,000 for businesses, depending on the severity of the offence. In addition, you risk having your installation shut down and facing criminal prosecution in the event of repeated offences.

The provincial authority or water board may impose various penalties. For minor offences, you will usually first receive a warning with a deadline for rectification. If you fail to comply within this period, penalty payments may be imposed, which can amount to thousands of euros per day.

In the event of serious breaches, the regulator may immediately impose a **penalty payment**. This means that you will pay a fine for every day that you fail to carry out measurements. These penalty payments are often higher than the cost of regular measurements.

In the worst-case scenario, your environmental licence may be revoked. This means you will have to cease your business activities until you are compliant again. For many companies, this is financially disastrous.

**Preventative measures** that help:

  • Draw up an annual plan for all mandatory measurements
  • Work with certified measurement agencies that remind you of deadlines
  • Invest in continuous monitoring where risks are high
  • Document all your dust control measures thoroughly

How we help with dust emission compliance

We make compliance easier by **reducing dust emissions directly at source**. Our biodegradable additives ensure that less dust is released, resulting in consistently lower measured levels and a reduced risk of exceeding limits.

Our approach to improving compliance:

  • Emissions reduction of 70–90 per cent through crust formation, foaming techniques and atomisation
  • Preventative dust control that systematically reduces measured levels
  • Ongoing support in complying with legal requirements
  • Bespoke solutions tailored to your sector and licence
  • Documentation support for reports to regulatory authorities

By effectively tackling dust at source, you need not worry so much about measurement results exceeding the limit values. This brings peace of mind and certainty to your business operations.
