Besluit activiteiten leefomgeving (Bal) – Dutch Decree on Living Environment Activities
The Besluit activiteiten leefomgeving (Bal) is a comprehensive national decree issued by the Rijksoverheid (National Government) of the Netherlands. It functions as a central pillar of the Omgevingswet (Environment Act) legal framework, consolidating various environmental regulations into a structured set of rules for activities impacting the physical living environment. The document defines which activities require an omgevingsvergunning (environmental permit) or a prior melding (notification) and sets out the general rules and specific environmental standards that operators must adhere to. This edition includes upcoming amendments scheduled for January 1, 2026, and applies to the territory of the Netherlands and its exclusieve economische zone (Exclusive Economic Zone).
The Bal is organized into 19 chapters and several technical annexes, covering a vast array of regulatory domains. These include energy use in buildings, the operation of stookinstallaties (combustion plants) and koelinstallaties (cooling systems), and the storage of hazardous substances including gases, liquids, and packaged goods. It governs industrial sectors such as basic chemistry, metal products, and mineral products, as well as waste management activities like autodemontage (vehicle dismantling) and recycling. Specific chapters are dedicated to complex enterprises under the Seveso-richtlijn, mining operations, agricultural sectors (including veehouderij, glastuinbouw, and open-field cultivation), and mobility-related emissions.
This document provides the technical thresholds, emissiegrenswaarden (emission limit values), and specifieke zorgplicht (specific duty of care) requirements that professionals must implement. It also details the bevoegd gezag (competent authority) for different activities, ranging from local municipalities to the Ministry of Infrastructure and Water Management.
General Provisions and Duty of Care
Chapter 1 and 2 establish the fundamental framework of the decree, defining the scope of environmentally harmful activities and discharge activities. It introduces the concept of the specifieke zorgplicht, a mandatory obligation for any party performing an activity to take all reasonable measures to prevent or limit adverse environmental effects.
- Article 1.1: References Annex I for comprehensive definitions used throughout the decree.
- Article 2.2: Lists the primary objectives, including safety, health protection, and environmental preservation (air, soil, and water quality).
- Article 2.3 - 2.9: Designates the competent authority for oversight, usually the municipal executive (college van burgemeester en wethouders), but also specific ministers or water boards depending on the activity.
- Article 2.11: Details the specific duty of care, requiring the use of best available techniques and the prevention of significant pollution.
Designation of Environmentally Harmful Activities
Chapter 3 acts as a directory for identifying regulated activities across cross-sectoral, complex, and industrial categories. It determines when an activity is considered environmentally harmful and whether it requires a permit or notification.
- Section 3.2.1: Regulates combustion plants with a thermal input greater than 100 kW.
- Section 3.2.7 & 3.2.8: Governs storage tanks for gases and liquids, specifying volume thresholds like 150 liters for certain compressed gases.
- Section 3.3.1: Covers Seveso-inrichtingen, which are high-risk industrial sites requiring stringent safety reporting.
- Section 3.4: Details rules for specific industrial branches such as metal processing, mineral products, and chemical product manufacturing.
- Section 3.8: Focuses on transport and logistics, including tankstations and the cleaning of transport containers.
Emission Limit Values and Environmental Norms
Chapter 4 contains the substantive technical rules for activities. It sets precise limits for emissions to air, water, and soil, often referencing standardized measurement methods (NEN-EN-ISO).
- Paragraph 4.3: Sets emission limits for large combustion plants (50 MW or more), including values for nitrogen oxides (NOx) and sulfur dioxide (SO2).
- Paragraph 4.4: Governs waste incineration and co-incineration plants, defining temperature requirements (e.g., 850°C or 1,100°C for hazardous waste).
- Paragraph 4.5: Specific rules for titanium dioxide manufacturing, including chloride and sulfate process standards.
- Paragraph 4.34: Regulates oplosmiddeleninstallaties (solvent installations), specifying consumption thresholds and diffuse emission percentages.
Soil Quality and Remediation
The decree integrates soil protection measures through modules in Chapter 5 and specific activity rules in Chapter 4, particularly regarding excavation and remediation.
- Paragraph 3.2.21 & 3.2.22: Covers excavation activities based on whether the soil quality is below or above the interventiewaarde bodemkwaliteit (soil quality intervention value).
- Article 4.1222a: Sets rules for temporary soil removal and the replacement of soil in its original profile.
- Section 5.2.1: Describes the eindonderzoek bodem (final soil investigation) required upon cessation of an activity to determine if pollution occurred.
- Annex IIa: Provides the definitive table for intervention values for metals, aromatic compounds, and chlorinated hydrocarbons.
Special Regulatory Domains
Specific sections address unique environmental concerns such as mobile source emissions, water management in the North Sea, and biodiversity protection.
- Chapter 7: Governs activities in the North Sea, including wind parks and the placement of subsea cables.
- Chapter 11: Regulates activities affecting nature, specifically Natura 2000-activiteiten and the protection of flora and fauna species.
- Chapter 15: Sets hygiene and safety standards for swimming pools and swimming ponds, including water quality parameters like free chlorine and Legionella monitoring.
- Chapter 18: Addresses CO2 emissions from work-related personal mobility for employers with 100 or more employees.
Frequently Asked Questions
What is the specific duty of care under the Bal?
Under Article 2.11, anyone performing an activity must take all measures that can reasonably be required to prevent adverse environmental effects, including using best available techniques and preventing significant pollution.
When does a combustion plant require an environmental permit?
According to Article 3.5, a permit is generally required for combustion plants with a thermal input over 100 kW if they burn fuels other than standard ones like natural gas, propane, or certain types of biomass under 15 MW.
What are the temperature requirements for hazardous waste incineration?
Article 4.98 states that the resulting gas must be heated to at least 850°C for two seconds, or at least 1,100°C if the hazardous waste contains more than 1% halogenated organic substances.
How are excavation activities regulated based on soil quality?
Activities are categorized in Sections 3.2.21 and 3.2.22 based on whether the volume exceeds 25 m³ and whether the soil quality is above or below the intervention values listed in Annex IIa.
What reporting is required for employers regarding mobility?
Under Chapter 18, organizations with 100 or more employees must report annually by June 30 on the total number of kilometers traveled by employees for commuting and business purposes, categorized by travel mode and fuel type.
What is the threshold for a Seveso establishment?
A Seveso establishment is designated under Article 3.50 if hazardous substances are present in quantities equal to or exceeding the thresholds in Annex I of the Seveso Directive, as implemented in the Dutch decree.
What are the water quality standards for swimming pools?
Table 15.16 specifies parameters such as free chlorine (0.5 to 1.5 mg/l for indoor pools), pH levels between 7.0 and 7.6, and a mandatory clear view of the pool bottom.
