Rule 5 requires three heat cycle rotations of active composting before final utilization. USDA
guidance varies, depending on the livestock species and the nature of the disease outbreak.
MDARD is looking to align with national standards based on research showing protective
methods for prevention of the spread of disease.
10. Is the subject matter of the rules currently contained in any guideline, handbook, manual,
instructional bulletin, form with instructions, or operational memoranda?
The rules currently adopt several published documents. Citations to the current versions of those
publications will be updated.
11. Are the rules listed on the department’s annual regulatory plan as rules to be processed
for the current year?
No.
12. Will the proposed rules be promulgated under Section 44 of the Administrative Procedures
Act, 1969 PA 306, MCL 24.244, or under the full rulemaking process?
Full Process
13. Please describe the extent to which the rules exceed similar regulations, compliance
requirements, or other standards adopted at the state, regional, or federal level.
The requirement for three heat cycle turns of the pile is the protective default setting. Since the
rules were last amended, multiple responses to Highly Pathogenic Avian Influenza have occurred,
and the USDA’s requirements for response to that disease require only two heat cycles. MDARD
is looking to align with federal requirements.
14. Do the rules incorporate the recommendations received from the public regarding any
complaints or comments regarding the rules? If yes, please explain.
The proposed change was prompted by joint USDA-MDARD response to Highly Pathogenic
Avian Influenza in spring 2022.
15. If amending an existing rule set, please provide the date of the last evaluation of the rules
and the degree, if any, to which technology, economic conditions, or other factors have changed
the regulatory activity covered by the rules since the last evaluation.
The rules had a substantial revision in 2011 and have been evaluated regularly since. The joint
USDA-MDARD response to Highly Pathogenic Avian Influenza in Michigan in spring of 2022
prompted discussion with the Michigan livestock industry to align this specific requirement and to
provide flexibility on composting requirements to account for the nature of a disease outbreak.
16. Are there any changes or developments since implementation that demonstrate there is no
continued need for the rules, or any portion of the rules?
No, the rules continue to provide needed direction on carcass disposal for both disease outbreaks
and natural mortality in manners that prevent spread of disease and protect Michigan’s
environment.
17. Is there an applicable decision record (as defined in MCL 24.203(6) and required by MCL
24.239(2))? If so, please attach the decision record.
No
MCL 24.239
