Chapter NR 400
AIR POLLUTION CONTROL DEFINITIONS
Units and abbreviations.
Ch. NR 400 Note
, Stats., directs the department of natural resources to organize a comprehensive program to enhance the quality, management and protection of the state's air resources. Chapters NR 400
are the central part of that program. Chapter 285
, Stats., also addresses the role of county government in establishing local air pollution control programs in cooperation with the department.
Ch. NR 400 Note
The objectives of these rules are to maintain standards of air quality at a level which will provide adequate protection to public health and welfare, and prevent detrimental effects on property and our environment.
Ch. NR 400 Note
Nothing in chs. NR 400
or in ch. 285
, Stats., prohibits a county or local jurisdiction from adopting more restrictive ordinances where local conditions indicate their need. Chapters NR 400
, all or in part, may be adopted by reference by a county or municipality.
Ch. NR 400 Note
It is the department's policy to seek reasonable uniformity among local air pollution control ordinances in order to make the statewide comprehensive program more effective and less complicated for all persons concerned.
Ch. NR 400 Note
Chapters NR 400
are subject to periodic revision to reflect changing state and federal mandates, advancing control technology, increasing knowledge of the effect on human health of sub-acute long term exposure to air pollutants, and increased knowledge of the effect of pollutants on plant life, animal life, soils and water resources.
This chapter applies to terms, units and abbreviations used in chs. NR 400
. In addition to the definitions in this chapter, other definitions may be included in individual chapters or sections in chs. NR 401
which are applicable to terms, units or abbreviations used in those respective chapters or sections. If an individual chapter or section defines a term which is also defined in this chapter, the definition contained in the individual chapter or section shall apply within that chapter or section, rather than the definition in this chapter.
This chapter is adopted under ss. 285.11
, Stats., to establish a set of definitions for terms commonly used throughout chs. NR 400
. Individual chapters or sections in chs. NR 401
may contain additional definitions for terms unique to an individual chapter or section or to a specified series of chapters.
