§257-1.1 Foreword

Air quality standards are designed to provide protection from the adverse health effects of air contamination; and they are intended further to protect and conserve the natural resources and environment and to promote maximum comfort and enjoyment and use of property consistent with the economic and social well-being of the community.

§257-1.2 Definitions

When used in this Part the following terms shall be interpreted to mean:

(a) Air quality standard. A numerically prescribed contaminant level that shall not be exceeded in a specified area of the State. Such contaminant levels may include instantaneous, short term, or long term concentrations of individual contaminants or grouping of contaminants having synergistic effects. Such standards may also be described in terms of net effects resulting from the occurrence of individual contaminants or grouping of various contaminants.

(b) Commissioner. The Commissioner of the New York State Department of Environmental Conservation.

§257-1.3 Application

(a) The standards shall be applicable, as specified in the individual Subpart, to the levels as described in Part 256 of this Title and as assigned in Subchapter C. In addition, emissions in a classified area shall be controlled to the extent required to be compatible with standards established in other areas.

(b) The procedures and techniques employed to determine ambient air concentrations of contaminants shall be as specified in the standard or in accordance with other methods or techniques acceptable to the commissioner. Acceptable methods may be published from time to time by the commissioner.

§257-1.4 Compliance

(a) No person shall permit, suffer or allow the emission of contaminants from an emission source which alone or in combination with emissions from other sources cause contravention of air quality standards promulgated in this Part.

(b) Notwithstanding the existence of specific standards, emissions of odorous, toxic, or deleterious substance in concentrations or of such duration that will affect human health or well-being, or unreasonably interfere with the enjoyment of property, or unreasonably and adversely affect plant or animal life shall not be permitted.
