Refining Directive

The refinery guideline of April 14, 1975 ( MBl. NRW p. 966) was an administrative regulation of the state of North Rhine-Westphalia for odor nuisance.

For North Rhine-Westphalia, it specified when an immission was to be classified as “significant nuisance” within the meaning of Section 3 (1) of the Federal Immission Control Act . Considerable nuisance was when certain immission limit values were exceeded in more than four percent of a year. The concept of the olfactory hour was introduced for this purpose.

The refinery guideline was created because there were complaints from residents in the Rhine area, especially in the south of Cologne , due to odor nuisance from the local oil processing industry. It was replaced in 1986 by the Odor Immissions Directive .
