Note: Par. (d) is shown as affected by 2011 Wis. Act 122. On May 24, 2011, the Joint Committee for the Review of Administrative Rules (JCRAR) adopted a motion under s. 227.26(2) (d), Stats., that suspended s. NR 407.03(2) (d) in part as shown below. Pursuant to s. 227.26(2) (f), Stats., JCRAR introduced 2011 Assembly Bill 195 and 2011 Senate Bill 138, in support of the JCRAR suspension. 2011 Senate Bill 138 was enacted, effective March 22, 2012, resulting in in the repeal of the rules as suspended by the May 24, 2011 JCRAR motion, as provided in s. 227.26(2) (i), Stats., and creating s. 285.28, Stats., as set forth below.

NR 407.03 (2) (d) The maximum theoretical emissions from the source for any hazardous air contaminant listed in Table A, B or C of s. NR 445.07 do not exceed the emission rate listed in the table for the hazardous air contaminant for the respective stack height. For the purposes of determining emissions under this paragraph, the owner or operator of a source is not required to consider emissions of hazardous air contaminants associated with agricultural waste.

285.28 Agricultural waste; hazardous air contaminants. The department may not regulate the emission of hazardous air contaminants associated with agricultural waste except to the extent required by federal law.

Note: Owners and operators of facilities emitting less than 3 tons of volatile organic compounds and 5 tons of particulate matter on an annual basis, or who engage in limited or no manufacturing activities, should refer to s. NR 445.11 prior to determining applicable requirements under this section.

(e) The source will not have maximum theoretical emissions of any single hazardous air pollutant listed under section 112 (b) of the Act (42 USC 7412(b)) that equal or exceed 10 tons per year or cumulative maximum theoretical emissions of all the hazardous air pollutants listed under section 112 (b) of the Act (42 USC 7412(b)) that equal or exceed 25 tons per year.

(f) The source is not subject to an emission limitation or emission standard under section 111 of the Act (42 USC 7411) excluding engines certified to meet the emission standards in 40 CFR part 60, subpart IIII or JJJJ for each fuel used.

(g) The source is not subject to an emission limitation or emission standard under section 112 of the Act (42 USC 7412), excluding section 112 (d) (5) or (r) (42 USC 7412(d) (5) or (r)).
