or Any other source that the Department determines has the potential to have a significant impact on air quality. In determining whether a source has the potential to have a significant impact on air quality, for purposes of §A(61) of this regulation, the Department shall consider the following: The quality, quantity, or characteristics of the pollutants discharged, including their toxicity; The location of the source, including its affects on an area that has not met ambient air quality standards; and Whether permit conditions are necessary to ensure that the source complies continuously with the requirements of the State air pollution control law. Section A of this regulation requires a State permit to operate for each emissions unit at a source covered by a Part 70 permit if the emissions unit is not provided for in the Part 70 permit and is a source listed in §A of this regulation. When the Part 70 permit is revised to include the emissions unit, the Part 70 permit constitutes the State permit to operate for that emissions unit. The Department, on a case-by-case basis, may exempt a source from the requirement for a State permit to operate on the basis of capacity, nature of equipment or materials, amount of emissions, or other evidence that the source has a limited potential to cause air pollution. The Department may issue a single State permit to operate for two or more sources located at a single facility or the Department may issue two or more State permits to operate for emission units within a source. A State permit to operate issued by the Department under §A(60) of this regulation is not a required permit to operate under Environment Article, §2-404(a)(1), Annotated Code of Maryland. Unless it is not practical to do so, a permittee shall maintain all permits in the vicinity of the source for which the permit was issued and make the permit immediately available to officials of the Department upon request. The Department may issue a general State permit to operate covering similar sources.
