Environmental permit

Environmental permits are decided by the municipal environmental protection authority or the Finnish Supervisory Agency.

Apply for an environmental permit for your activity if it

  • poses a risk of environmental pollution
  • is listed in the appendix to the Environmental Protection Act
  • is located in a groundwater area
  • may cause pollution of a water body
  • may cause pollution of a ditch or similar through wastewater discharge
  • causes unreasonable disturbance to neighbours, such as noise
  • is undergoing substantial changes

How to proceed

Seek consultant assistance for the application.

Complete your application using the forms available on the environmental administration website below. Send your application with attachments by email to Hämeenlinna City Environmental Protection at kaupunkirakenne@hameenlinna.fi when the activity is located in Hämeenlinna or Hattula.

The conditions of an environmental permit limit the impacts of the activity to a reasonable level. The processing time for an application with the municipal environmental protection authority is approximately 7 months, and a fee is charged according to the established charge.
