Even if your facility is a small source of air emissions, you may still need an air permit or authorization depending on your state or local air permitting authority. When dealing with permitting, you often need to consider not only the amount of air emissions your operations generate, but the amount your operations could generate. Each state or local air permitting authority has different statutes or rules that govern what is required of small sources of air emissions.

Changing Standards

此外，这些法规和规则通常会发生变化。例如，由于最近明尼苏达州允许规则的更改，以前由许可证监管的一些小来源不再需要许可证或支付排放费。明尼苏达污染控制局（MPCA）现在拥有其他类别的“有条件豁免来源”，包括汽车身体修正，涂层，木工，混凝土制造和汽油服务站。这些类型的来源仍有技术标准，但标准旨在更简单，更容易遵循许可证。它们还允许来源避免文书工作和空运费用。MPCA网站有额外的information在这个新选择。

Similarly, at the federal level, policy changes within the last few years affect what emissions standards may apply to existing sources that emit a class of pollutants called hazardous air pollutants (HAPs). This change has also allowed some small sources to no longer require air permits or to qualify for less complicated air permits. The former policy, commonly known as the “once in, always in” policy, authorized that once a source was a major source of HAPs, it mustalwaysbe a major source of HAPs, and therefore require a Title V permit. Under the revised interpretation, sources that lower their emissions or take limits below certain levels are no longer required to be major sources and may no longer require a Title V permit.

Permitting Options

The recent rule modifications mean that for small sources like auto-body repair shops, wood-working operations, or miscellaneous coating operations, knowing the right type of permit or authorization for your business may not be so simple. Our consultants can help you determine if you need an air permit and make sure that you are taking advantage of any changes that offer regulatory relief.

Don’t forget — even as a small source, you may be subject to hazardous waste, tank, or spill prevention requirements depending on the chemicals you use and store on site. Braun Intertec has expert environmental consulting professionals that can help you navigate these regulatory programs so that you have all the proper environmental permits, plans, and licenses in place.
