Enimmäisvuorokertymät

Enimmäisvuorokertymät, often translated as maximum daily accumulations or daily limits, are a concept primarily used in Finnish environmental regulations and permitting processes. They define the maximum allowable amount of a specific substance that can be released into the environment within a 24-hour period. These limits are crucial for controlling pollution and ensuring that the cumulative impact of emissions on ecosystems remains within acceptable bounds.

The purpose of setting enimmäisvuorokertymät is to prevent short-term, high-concentration releases that could cause immediate harm to the environment or human health. While average daily or annual limits might allow for fluctuations, the daily maximum ensures that even during peak operational periods, emissions do not exceed a critical threshold. This approach complements other emission standards, such as those based on concentration or annual total amounts.

These limits are typically established during the environmental permitting of industrial facilities, wastewater treatment plants, and other operations that have the potential to release pollutants. The specific substances for which enimmäisvuorokertymät are set can vary widely and include parameters like heavy metals, organic compounds, nutrients, or particulate matter. The determination of these limits is based on scientific risk assessments, environmental quality objectives, and the best available techniques for pollution control. Compliance with enimmäisvuorokertymät is monitored through regular sampling and analysis of emissions.
