Directive 019 in the Mining Industry (2025): Everything You Need to Know About Noise and Vibration Requirements

On February 13, 2025, the MELCCFP released a significant update to Directive 019, which regulates the mining industry in Quebec. This directive strengthens environmental requirements, particularly in the areas of noise, vibration and overpressure control. But what exactly has changed since the 2012 version? When do the environmental requirements apply and what are their implications? Our acoustics and vibration experts have reviewed the latest revisions to help you stay compliant - and ensure a positive coexistence with neighbouring communities.

What is Directive 019?

Directive 019 pertaining to the mining industry, published by the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP), sets the environmental standards that must be met by proponents of both new mining projects and modifications to existing operations. It outlines requirements across multiple areas, including:

  • Noise, ground vibrations and air overpressure.
  • Maximum limits permitted for these contaminants.
  • Measurements and monitoring methods required by the Ministry.
  • Communication programs and complaint management.
  • Etc.

The 2025 update of the Directive, released in February, introduces stricter standards than its predecessor. It is aimed to reinforce the environmental framework supporting sustainable mining development and acts as a key reference for impact assessments and permitting applications.

When Must Your Mining Project Comply With the 2025 Edition of Directive 019?

Although the 2025 version of Directive 019 came into effect on February 13, 2025, it does not appear to be automatically applicable to all mining projects. The 2025 version would be applied in the following cases:

For example, if your mine is already in operation and you are planning to increase production, add new equipment, or make any changes that could increase environmental emissions, especially noise, you will need to comply with the 2025 edition of Directive 019 for the modified aspects. While this may seem straightforward, the Directive goes into great detail about mine additions that require the application of version 2025.

Noise: What Impact Will the New 2025 Regulation Have on Your Mining Project

With regard to noise management, Directive 019 continues to refer explicitly to Instruction Note 98-01 “Handling Noise Complaints and Requirements for Noise-generating Companies” (NI98-01).

However, several aspects have been updated since the previous edition. Here's a look at what's new - and more importantly, what these changes mean in practical terms for mining projects.

 

 

Noise Monitoring Radius

In the 2025 version of the Directive, the noise assessment and monitoring distance has not been extended to 1 km, with the following implications:

  • It is obligatory to carry out a predictive study of the noise climate when a dwelling or public establishment is located within a one-kilometer radius of the mine, to ensure compliance with the permissible noise levels set out in NI98-01.
  • Where applicable, the Directive states that the predictive noise climate study must include the following elements:  
    • Identification of mobile and fixed noise sources (temporary, permanent).
    • Location of noise sources.
    • The duration by which these noise sources will be used (per day, week, or year) and at what time (hours).
  • If applicable, what measures will be used to reduce noise levels, and what level of noise reduction is planned?
  • For the modalities of the predictive study (modeling), the Directive continues to refer to NI 98-01.
 

Noise Monitoring Program

Depending on the context, environmental noise monitoring is now a mandatory requirement at all stages of the mining cycle: exploration, development, operation, and site closure.

This monitoring enables validation of compliance with regard to noise levels and to better anticipate at-risk situations.

  • A summary of noise climate monitoring results must be included in the annual report. 
  • Whenever the maximum noise level is exceeded, reports must be sent to the Ministry. 
  • In addition, if maximum noise levels are exceeded as a result of mining project operations, noise sources must be identified and corrective measures implemented.
     

Notes from our experts

To meet the Ministry's requirements and optimize your operations, it's essential to implement a continuous noise monitoring system that can automatically generate reports and distribute them to relevant stakeholders based on measured levels.

In the event of overruns, real-time alerts (sent by text or email) with live access to data through a high-performance, user-friendly web platform, keeps you informed around the clock, as if you were on-site.

Partnering with a team of acoustics and vibration experts can make all the difference. Their insights help to accurately identify noise sources and ensure that any corrective measures are both effective and tailored to the specific needs of your project.

 

Noise Complaints and Data Retention Periods

The 2025 edition of Directive 019 also includes new requirements for noise complaint management, data retention periods, and communications with the Ministry.

Did you know that a complaint can arise even if the perceived noise is within the current limits?

In some cases, even noise that complies with regulatory limits can still be perceived as disturbing by local communities, thus resulting in complaints. Factors such as low ambient noise (when mining activity is absent), the introduction of new equipment, the relocation of mobile equipment or even certain noise characteristics can all increase the perceived impact of sound, making it more noticeable and therefore disturbing to neighbouring communities.

However, if no regulatory threshold is exceeded, a standard noise monitoring system that only records audio during exceedances may fail to capture the noise event that triggered the complaint. This limits the mine’s ability to properly analyze the situation and determine appropriate corrective action.

Analyzing such complaints becomes particularly challenging without a way to “replay” what was actually heard. Weather conditions, which directly influence sound propagation, can vary from day to day and changes in on-site equipment can alter the noise environment at any time.

Without a continuous audio recording, it becomes nearly impossible to accurately reconstruct the sound environment at the time of the complaint or to confidently determine the best response.

In contrast, a monitoring system with continuous audio recording records allows you to review the exact moment the noise occurred, hearing what local residents heard, even when no thresholds had been exceeded.

This allows you to better understand the community’s experience, clearly communicate the context of the noise, determine whether your operations were responsible, and, if so, respond with effective and timely corrective measures.

Vibrations: What Impact Will the New 2025 Regulations Have on Your Mining Project?

For vibration, the 2025 version of Directive 019 introduces the following changes:

  • A standardized limit of 12,7 mm/s is allowed at the point of impact during blasting, regardless of the type of mine and the distance between the mine and sensitive receptors.
  • The maximum limit of 128 dB limit for air overpressure is maintained.
  • Vibration monitoring is mandatory for all stages of the mining cycle, including exploration.
  • A communication program is required with residents who reside within a 1 km perimeter and with the municipalities concerned.
  • All data pertaining to the monitoring of blasting activities must be kept for a minimum of 5 years.

Note: Unlike the 2012 version of Directive 019, the 2025 version no longer imposes a specific number of vibration monitoring stations to be installed. It does, however, require that at least one station be placed in close proximity to the nearest fixed dwellings to the mining site, even if situated outside the 1 km perimeter, in order to adequately measure the impact of blasting. A request for exemption may be submitted to the Ministry when the nearest points of impact are outside the area affected by blasting.

 

 

Communication Program

A communication program has not been made mandatory for blasting operations. Although Directive 019 does not detail the elements of a communication program, certain best practices are to be favoured, including:

  • Informing the public, in advance, of activities likely to cause vibration (e.g. date, time and duration of blasting operations).
  • An explanation of the prevention and mitigation measures that have been put in place.
  • Managing Complaints: recording each complaint and ensuring that they are handled appropriately.
  • Etc.
 

Taking Quality Measurements for Vibrations

Although Directive 019 specifies certain limits, it does not specify reference documents or standards, as is the case for noise in NI98-01, in terms of the instrumentation to be used.

In cases such as this, in order to have data that is reliable and defensible, the use of seismographs complying with recognized standards in the field is highly recommended. The best-known reference documents, generally widely accepted in the mining community and used in North America, come from the International Society of Explosive Engineers (ISEE), both for sensor specifications and expected accuracy. 

Although not explicitly stated in the standard, following good practices ensures that measured data will be of the highest quality and carried out in accordance with the rules of the trade.

All data associated with monitoring blast activities must be recorded in a register, be kept for at least 5 years , and made available to the Ministères in the event of an audit or inspection.

If a blast results in a particle velocity, air overpressure thresholds have been exceeded, or in projections off the mine site, the operator must inform the Ministry without delay and implement the necessary corrective measures.

The use of an automated system, such as the patented Master Trigger™ Blast Monitoring solution that generates synthetic vibration reports immediately after a blast, represents a prime tool for automating a task that is all too often time-consuming when performed manually.

Social Acceptance: A Key Element of Directive 019

With its 2025 version, Directive 019 seems to aim its focus on giving local communities a more important role when it comes to mining projects. Features include:

  • Greater transparency for the public, with the introduction of the Noise Complaints Register and the addition of a communication program, in the event of blasting.
  • Stricter requirements regarding controlling noise and vibration pollution to promote social acceptance and cohabitation with neighbouring communities.
  • Accountability of mining operators, who must maintain proof of compliance, by retaining measured data over several years.

Ultimately, this focus aims to develop a climate of trust between the mining industry and local communities, thus promoting social acceptance. Although the 2025 version of the MELCCFP Directive addresses social acceptance more explicitly than before, this is an issue that Soft dB is very familiar with in terms of noise and vibration.

Summary of Everything You Need to Know About the 2025 Edition of Directive 019 on Noise and Vibration

The key takeaway points of the MELCCFP Directive 019 - Version 2025:

  • Noise assessment distance has been extended to 1 km.
  • Noise and vibration monitoring is needed at every stage of the mining cycle.
  • Extended data retention period: 5 years (instead of 2).
  • A mandatory public communication program (vibration) and proactive complaint management (noise).
  • A uniform maximum vibration velocity limit of 12.7 mm/s, measured at the point of impact, regardless of distance or type of mining activity.
  • The obligation to install at least one measuring station in close proximity to the nearest fixed dwelling to the mine site, even if outside the 1 km perimeter, in order to adequately measure the impact of blasting. When the nearest points of impact are outside the area affected by blasting, it is possible to submit a request for exemption to the Ministry.

Although these requirements may seem restrictive, they reinforce the goal of improved cohabitation between the mining industry and neighbouring communities. Companies prepared to comply with these new standards demonstrate their environmental and social commitment, which in turn ensures greater long-term acceptance.
