PART 7. EMISSION LIMITATIONS AND PROHIBITIONS--  
NEW SOURCES OF VOLATILE ORGANIC COMPOUND EMISSIONS  
R 336.1701 "New source" defined.  
Rule 701. For the purpose of this part, a "new source" means any process or process  
equipment which is either placed into operation on or after July 1, 1979, or for which an  
application for a permit to install, pursuant to the provisions of Part 2 of these rules, is  
made to the department on or after July 1, 1979, or both, except for any process or  
process equipment which is defined as an "existing source" under R 336.1601.  
History: 1980 AACS; 1981 AACS; 2002 AACS.  
R 336.1702 New sources of volatile organic compound emissions generally.  
Rule 702. A person who is responsible for any new source of volatile organic  
compound emissions shall not cause or allow the emission of volatile organic compound  
emissions from the new source in excess of the lowest maximum allowable emission  
rate of the following:  
(a) The maximum allowable emission rate listed by the department on its own  
initiative or based upon the application of the best available control technology.  
(b) The maximum allowable emission rate specified by a new source  
performance standard promulgated by the United States environmental protection  
agency under authority enacted by title I, part A, section 111 of the clean air act, as  
amended, 42 U.S.C. §7413.  
(c) The maximum allowable emission rate specified as a condition of a permit to  
install or a permit to operate.  
(d) The maximum allowable emission rate specified in part 6 of these rules which  
would otherwise be applicable to the new source except for the date that the process or  
process equipment was placed into operation or for which an application for a permit to  
install, under the provisions of part 2 of these rules, was made to the department. If the  
part 6 allowable emission rate provides for a future compliance date, then the future  
compliance date shall also be applicable to a new source pursuant to this subdivision.
