NR 445.13(2)(d)
(d) Paragraph (b) notwithstanding, the department shall consider all of the following in determining whether to list a hazardous air contaminant in Table A, B or C of
s. NR 445.07:
NR 445.13(2)(d)1.

NR 445.13(2)(d)2.
2. An evaluation of the expected population exposure to the contaminant and the related risks.
NR 445.13(2)(d)3.
3. An evaluation of alternative control strategies, including emission limitations, that includes consideration of costs.
NR 445.13(3)
(3) Reevaluation of listing decision. The owner or operator of an affected source or other interested party may submit a written request to, and the department may, reevaluate a determination to list or not to list a substance as a hazardous air contaminant in this chapter. The request shall provide new or additional information for the department's consideration. In conducting a reevaluation, the department shall consider the criteria set forth in
sub. (2) (b) and
(c) and other information that it deems relevant.

NR 445.14 Hazardous air contaminant studies. NR 445.14(1)(1) The department may conduct studies of individual substances or categories or sources of substances if it determines that unique complexities may warrant alternative approaches to those listed in this chapter, or if the department otherwise needs additional information to determine whether to list the contaminant in Table A, B or C of
s. NR 445.07.
NR 445.14 Note
Note: Unique complexities may be the result of the nature of the emissions, the sources of emissions, the management of emissions or other factors. The studies will not include a re-evaluation of the classification of the substance as reported by the American Conference of Government Industrial Hygienists, the United States environmental protection agency, the International Agency for Research on Cancer, or the National Toxicology Program.
NR 445.14(2)
(2) The department staff shall, in consultation with affected industry, public health officials and other interested parties, undertake 2 separate studies of the emissions of amorphous and crystalline silica and wood dust. The studies shall evaluate the sources and amounts of emissions and alternative strategies for minimizing public health risks. The department staff shall report progress on the studies to the natural resources board by July 1, 2006.
NR 445.14(3)
(3) The department shall evaluate the listing of substances added to this chapter on July 1, 2004, using the criteria set forth in
s. NR 445.13 (2) (d) prior to listing additional substances in Table A, B or C of
s. NR 445.07.

NR 445.15 Additional provisions related to the control of hazardous air contaminants. NR 445.15(1)
(1) The department staff shall consult with the department of health services prior to incorporating an alternative emission limit under
s. NR 445.07 (1) (b) in an order or a permit.
NR 445.15(2)(a)(a) If it is determined that emissions of a hazardous air contaminant from a facility do not comply with an applicable emission requirement for that contaminant, the owner or operator will not be out of compliance with respect to that contaminant if the owner or operator satisfies all of the following:
NR 445.15(2)(a)1.
1. Exercised due diligence and followed the procedures and other provisions in this subchapter for identifying and quantifying hazardous air contaminants.
NR 445.15 Note
Note: Examples of procedures in this subchapter include stack thresholds, risk-based modeling and applicability criteria for sources of incidental emissions.
NR 445.15(2)(a)2.
2. Based on the results of
subd. 1., either concluded that no emission requirements applied to that contaminant or complied with all emission requirements that applied to that contaminant.
NR 445.15(2)(a)3.
3. Within 21 calendar days of making the determination that a hazardous air contaminant does not comply with an applicable emission requirement for that contaminant, submits the determination in writing to the department.
NR 445.15(2)(a)4.
4. By the later of the deadlines in
s. NR 445.08 (6) or 90 calendar days after making the determination of noncompliance, certifies that the facility meets provisions applicable for the hazardous air contaminant.
NR 445.15(2)(b)
(b) After receipt of a written request, the department may, in writing, extend the deadline for achieving compliance with the deadline in
par. (a) 4.
NR 445.15 Note
Note: The address for submittal of information and requests for an extension from the deadline in par. (a) 4. is:
Wisconsin Department of Natural Resources

Attention: NR 445 Safe Harbor Determinations.
NR 445.15(2)(c)
(c) Notwithstanding
par. (a), the department retains the authority to order the owner or operator to come into compliance with applicable requirements within a specific time period shorter than the 90 calendar days whenever compliance in the shorter period of time is feasible and necessary to protect public health and the environment.
NR 445.15(3)
(3) The department shall review emissions reported under
ch. NR 438 from sources of the contaminants listed in
s. NR 410.04 (2) (b) 5. If the department determines that emissions are of such quantity, concentration or duration that a concentration greater than 2.4% of the contaminant's threshold limit value-time weighted average established by the American Conference of Governmental Industrial Hygienists, in the Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices for 2000, incorporated by reference in
s. NR 484.11 (2) (c), is expected to occur off of the source's property, it may establish a limitation in a permit or order that will ensure the source does not cause concentrations off of the source's property that exceed 2.4% of the threshold limit value-time weighted average for any consecutive 24-hour averaging period.
NR 445.15(4)
(4) The department staff shall consult with the department of health services prior to establishing an emission limit, in a permit or order, for any hazardous air contaminant that is not listed in Table A, B or C of
s. NR 445.07.
NR 445.15(5)
(5) The department may establish emission limitations for hazardous air contaminants for sources in permits or general or special orders issued by the department.
