Immission and noise impacts of projects

Does a project affect both air quality and noise? We prepare an integrated assessment using the same data — consistent documentation for EIA, the regional authority and KHS.

Service overview

When you need this service

  • A project has concurrent impact on air quality and noise
  • An authority requires immission and noise evaluation
  • You are preparing EIA or project notification
  • You need variant comparison of technology location

What we provide

  • We consolidate immission and noise briefs for one project
  • We model technology location variants
  • We prepare documentation for EIA, the regional authority and KHS
  • We deliver one consolidated output for the investor and designer

What you receive

  • integrated immission and noise impact assessment
  • variant comparison and measure recommendations
  • documentation for EIA, authorities and investor

How to get started

For an initial scope assessment, please send:

  • project documentation and site layout
  • source technical parameters and operating schedule
  • project variants

Practical project examples

  • immission and noise impacts of an industrial site
  • assessment of a landfill, biogas plant or production project
  • technology location variants from air quality and noise perspectives

Typical mistakes and risks

  • Addressing noise and immissions separately without link to the same project
  • Incomplete input data for modelling
  • Overlooking transport or ancillary sources on site

FAQ for this service

When is a dispersion study required?

Prepare a dispersion study for a new or modified emission source, technology change, capacity increase, EIA, permitting proceedings or on instruction from the regional authority.

Who may prepare a dispersion study?

A dispersion study may be prepared by an authorised person within the relevant scope.

What documentation is needed for a dispersion study?

Typically a technology description, emission parameters, stack height and diameter, volumetric flow, temperature, operating hours, site layout, transport data, surrounding development data and the study purpose.

Can a dispersion study be prepared for variants?

Yes. For projects in preparation, multiple technology, stack, operating mode, capacity or transport intensity variants can be compared. Variant assessment helps the investor and designer find a technically and environmentally preferable solution.

When is a noise study appropriate?

A noise study is appropriate before implementing a new noise source, during technology change, for industrial sites, HVAC, heat pumps, transport, storage and production operations, or as documentation for building proceedings, KHS or EIA.
