The odor immissions guideline (GIRL), in the long title determination and assessment of odor immissions , is a regulation of the state of North Rhine-Westphalia . It goes back to the odor pollution guideline of the federal state committee for pollution control (LAI) 2004.
The GIRL is used to record and assess odors as immission in accordance with Section 3 of the Federal Immission Control Act . In 1986, it replaced the Refinery Directive 1975 and the implementing decree for the TA Luft 1986 in North Rhine-Westphalia . Adjustments were made in 1993, 1995, 1998, 2004 and 2008. It is important for approval procedures and monitoring.
The current version is from November 5, 2009 ( MBl. NRW. No. 31 of November 27, 2009 p. 533).
Significant annoyance can be assumed if odor hour frequencies of more than 10 or even 15% per year occur in a local situation. According to number 3.1 (immission values):
- According to this guideline, only clearly perceptible odor immissions may be assessed, i.e. those odor immissions that can be identified with sufficient certainty and unequivocally based on their origin from systems or groups of systems, i.e. can be distinguished from odors from vehicle traffic, domestic fires, vegetation, agricultural fertilization measures or the like . Odor immissions are generally to be rated as considerable nuisance if the total exposure IG (number 4.6) exceeds the immission values IW specified in Table 1. The immission values are relative frequencies of the odor hours (see number 4). "
