Agency Report to JCAR-Page 2
R 336.1902, “Adoptions of standards by reference,” provides information for the reference material
appearing throughout the Michigan Air Pollution Control Rules. This information consists of the
following: physical and web addresses, price, and publication dates. The proposed revisions consist
primarily of updates to reference prices to align with what is currently offered by the respective
sources, including the AQD. The update also revises the publication dates referenced. Revisions were
also made to the physical and web addresses listed in the rule in order to reflect the current
information and availability of these reference materials from their respective agencies.
R 336.1974, “Emission standards for existing commercial and industrial solid waste
incinerators” (CISWI), addresses the Section 111(d) requirement under the Clean Air Act to limit
emissions of air pollutants from CISWI units as stated in Title 40 of the Code of Federal Regulations
(CFR), Part 60, Standards of Performance for New Stationary Sources, Subpart DDDD, Emission
Guidelines and Compliance Times for Commercial and Industrial Solid Waste Incineration Units. The
proposed revisions to R 336.1974 address the most recent amendments to Subpart DDDD made by
the United States Environmental Protection Agency (USEPA) on March 18, 2019. The rule revisions
will account for the changes to Subpart DDDD. The proposed revisions to R 336.1974 will result in a
rule that directly mirrors Subpart DDDD except for the compliance date. The compliance date of the
rule, as required under MCL 24.247, will be 7 days after rule promulgation. The compliance date in
Subpart DDDD has passed, so Michigan units will need to be in compliance on the effective date of
the rules.
