Regulation on emission monitoring techniques

22/02/2025

Nanoen – To ensure accurate air emission monitoring results, in addition to using appropriate measuring equipment, the air emission sampling platform plays a critically important role.

The working platform is specified in Circular No. 10/2021/TT-BTNMT and applies to organizations and individuals involved in environmental monitoring activities.

In this context, what is a working platform? What technical requirements must a working platform satisfy? Let's find out with Nanoen in the article below!

1. What is a working platform?

The working platform is a flat surface designed to support the operation, maintenance, inspection, and sampling of emissions from chimneys or exhaust pipes at facilities.

The working platform must ensure:

Sufficient width for workers and equipment to move safely.
Sturdy design, slip-resistant, and able to withstand heavy loads.
Compliance with technical and occupational safety regulations.

Note: The layout of the working platform will vary depending on the specific conditions of each factory to ensure it aligns with actual conditions and monitoring requirements. For more details, please contact Nanoen for specific advice.

2. Emission monitoring techniques

Emissions monitoring is the process of measuring and analyzing the physical and chemical properties of emissions to assess pollution levels and the effectiveness of control measures. This process is specified in Appendix 5 of Circular 10/2021/TT-BTNMT and consists of the following main steps:

2.1 Determine the location of the sampling port

For pipelines with a diameter ≥ 300 mm

The sampling port must be placed on the cross-sectional plane of the straight flue pipe section.
Determination method: The sampling port position on the chimney is determined by identifying segments A and B, the inner diameter D, and satisfying the conditions B ≥ 2D and A ≥ 0,5D. In an ideal case, the sampling port position satisfies the conditions:

2.2 Requirements for sampling ports

Diameter: 90 mm - 110 mm, with cover.
Round chimney: Minimum of 02 sampling ports in two perpendicular directions.

Rectangular chimney: The number of sampling ports depends on the length/width ratio.

2.3 Determine the number of sampling ports

The number of sampling ports is determined based on the chimney structure to ensure that the measurement data is representative of the actual emission sources.

The above information regarding the working platform and emission monitoring techniques has been compiled by Nanoen to facilitate our customers.

3. Why should a standard-compliant working platform be installed for emissions monitoring?

A working platform ensures occupational safety and helps to optimize the monitoring process and improve the accuracy of measurement results.

Plugging and Sealing Unused Wells in Vietnam: Regulations, Procedures and Key Requirements for Businesses [2026 Update]

Nanoen – An unused well may still pose risks to groundwater resources. If it is not properly handled, the well can become a pathway through which surface water and contaminants migrate into aquifers or allow water to circulate between different water-bearing layers.

Surface Water Extraction Dossier 2026: Exemption, Registration, or Licensing?

Nanoen – Not all surface water extraction activities require a permit. Under Decree 23/2026/ND-CP, businesses fall into three categories depending on their usage purpose, scale, and water source: exempt, registration required, or licensing required. Identifying your category correctly from the start ensures proper procedures, accurate paperwork, and avoids delays. Here is a breakdown of key regulations and preparation steps for 2026.

Switching to Environmental Registration: How to Save Costs While Controlling Legal Risks?

Nanoen – Environmental registration is not merely an administrative procedure, but the highest legal commitment a business can make regarding its waste generation sources and treatment facilities.

Continue with Environmental Permit or Switch to Environmental Registration: Which Option Is Right for Businesses?

Nanoen – Many businesses that have already been granted an Environmental Permit may, under new regulatory thresholds, no longer be subject to Environmental Permit requirements and may be eligible to switch to Environmental Registration.

Understanding Environmental Registration and the Ex-Post Inspection Mechanism under Resolution No. 66.19/2026/NQ-CP

Nanoen – Resolution No. 66.19/2026/NQ-CP introduces a new regulatory approach to environmental registration, simplifying procedures while strengthening ex-post compliance responsibilities. Businesses need to clearly understand the nature of environmental registration, distinguish between provincial and commune-level receiving authorities, and properly prepare dossiers, operational data, and supporting records to ensure compliance throughout their operations.

Key Changes in EIA Regulations Under Resolution 66.19/2026/NQ-CP

Nanoen – Resolution 66.19/2026/NQ-CP, enacted on May 18, 2026, has introduced significant amendments to environmental regulations, particularly regarding Environmental Impact Assessment (EIA) procedures. This is considered a milestone in administrative reform, aimed at streamlining regulatory procedures, accelerating dossier processing times, and strengthening decentralization to local authorities for project appraisal and approval.
