· Complements CONAMA Resolution 5/89
Establishes provisions related to air quality standards, as foreseen by PRONAR.
The NATIONAL ENVIRONMENT COUNCIL – CONAMA, in the use of the power bestowed upon the Council by item II of art. 6 of Law 7.804 of July 18, 1989 and in light of the provisions set by Law 8.028 of April 12, 1990 and Decree 99.274 of June 6, 1990 and,
Considering the need to broaden the number of atmospheric pollutants that are monitored and controlled throughout the Country;
Considering that Administrative Order GM 0231 from April 27, 1976 foresaw the establishment of new standards for air quality whenever demanded by new scientific acknowledgements on the subject matter;
Considering the provisions foreseen by CONAMA Resolution 5 from June 15, 1989 which creates the National Air Quality Control Program “PRONAR”, decides:
Art. 1 Air quality standards are the concentrations of atmospheric pollutants which, if surpassed, can be hazardous to human health, safety and the wellbeing of the population as well as possibly causes of damages tothe fauna and flora, material goods and the environment in general.
Single paragraph. Na atmospheric pollutant is understood as any form of substance or energy with an intensity and quantity, concentration, timing or characteristics that are not in harmony with established levels and which render, or can render the air:
I – unfit, hazardous or injurious to human health;
II – undesirable for public wellbeing;
III – hazardous to goods, fauna and flora;
IV – detrimental to safety, the use and enjoyment of property and normal community activities.
Art. 2 The following concepts are hereby established for all purposes of this Resolution:
I – Primary Air Quality Standards are pollutant concentrations that if surpassed may be hazardous to the health of the population.
II – Secondary Air Quality Standards are pollutant concentrations below those that can have any adverse effects on the wellbeing of the population as well as having minimal effects of the fauna, flora, goods and the environment in general.
Single paragraph. Air standard quality standards are objectives that should be reached through control strategies set by emission standards and must serve as guidelines for the creation of Regional Air Pollution Control Plans.
