R 323.2410 Management practices.  
Rule 2410. (1) A person shall not apply bulk biosolids to the land if it is likely to  
adversely affect a threatened or endangered species listed under section 36503 of the  
act or its designated critical habitat.  
(2) A person shall not apply bulk biosolids to agricultural land, a forest, a public  
contact site, or a reclamation site that is flooded, saturated with water, frozen, or snow-  
covered so that the bulk biosolids enter a wetland or other waters of the state.  
(3) A person may subsurface inject bulk biosolids on frozen or snow-covered ground  
as long as there is substantial soil coverage of the applied biosolids. A person shall  
Page 15  
not surface apply bulk biosolids, other than exceptional quality biosolids, on frozen  
or snow-covered ground, unless otherwise approved by the department.  
(4) A person shall not apply bulk biosolids on lands having a slope of more than 6%  
for surface application or more than 12% for subsurface injected biosolids, unless the  
person uses the bulk biosolids in accordance with a department-approved site  
management plan.  
(5) A person shall apply bulk biosolids to agricultural land, a forest, a public  
contact site, or a reclamation site at an application rate that is equal to, or less than, the  
agronomic rate, unless the person that applies bulk biosolids in accordance with a  
department-approved site management plan.  
(6) A generator or distributor shall affix a label to the bag or other container in  
which biosolids are sold or given away for application to the land or the generator or  
distributor shall provide an information sheet to the person who receives biosolids sold  
or given away in another container for application to the land. The label or information  
sheet shall contain all of the following information:  
(a) The name and address of the person who prepared the biosolids that are sold or  
given away in a bag or other container for application to the land.  
(b) A statement that the application of the biosolids to the land is prohibited  
unless applied according to the instructions on the label or information sheet.  
(c) The annual whole biosolids application rate for biosolids that do not cause any  
of the annual pollutant loading rates in table 4 of R 323.2409(5)(d) to be  
exceeded.  
(7) A person that applies biosolids shall perform soil fertility tests on soils sampled  
from each application site before initial biosolids application. The person shall  
resample and test on a regular basis so that the last soil fertility test is not more than 2  
years old at the time of the next biosolids application.  
(8) For agricultural land, a person shall apply biosolids in accordance with  
agronomic rates. If the Bray P1 soil test level exceeds 300 pounds (P) per acre (150  
ppm), or if the Mehlich 3 soil test level exceeds 340 pounds (P) per acre (170 ppm) in  
site soils, then the person shall not apply biosolids until the soil P test level decreases  
to less than 1 of these values.  
(9) For silvicultural land, such as forestland and tree farms, a person shall base the  
agronomic rate for silvicultural land on the quantity of plant-available nitrogen (PAN)  
that growing trees will take up annually. A person may reapply biosolids at rates that  
will provide PAN additions up to a maximum of 5 years, using the annual PAN additions  
listed in table 5 to calculate total PAN additions for 1 year up to a 5-year maximum  
for the particular tree species and age of the stand receiving biosolids. A person may  
reapply biosolids after the time interval selected for the previous application expires,  
as long as the trees are still growing. If the Bray P1 soil test level exceeds 200 pounds  
(P) per acre (100 ppm) or the Mehlich 3 soil test level exceeds 220 pounds (P) per acre  
(110ppm), then a person shall not apply biosolids until the soil P test level decreases to  
less than 1 of these values.

R 323.2416 Reporting; fees; biosolids land application fund; creation.  
Rule 2416. (1) Beginning in state fiscal year 1998, an annual biosolids land  
application fee is imposed upon biosolids generators and biosolids distributors. The  
biosolids land application fee is an amount equal to the sum of an administrative fee  
and a generation fee.The administrative fee is $400.00 for each biosolids generator or  
distributor that land applies. The department shall set the generation fee as provided by  
subrule (2) of this rule. The department shall set the generation fee so that the annual  
cumulative total of the biosolids land application fee to be paid in a state fiscal year is, as  
near as possible, $650,000.00 minus the amount in the fund created under subrule (5) of  
this rule carried forward from the immediately preceding state fiscal year. Starting with  
fees to be paid in state fiscal year 1999, the department shall adjust the $650,000.00  
amount annually for inflation using the Detroit consumer price index.  
(2) Each biosolids generator and biosolids distributor shall annually report to the  
department for each state fiscal year, beginning with the 1997 state fiscal year, the  
number of dry tons of biosolids it generated or the number of dry tons of biosolids in  
derivatives it distributed that were applied to land in the state of Michigan in the  
state fiscal year. A biosolids generator that does not land apply shall report zero. A  
biosolids generator located in the state of Michigan that land applies outside the state  
of Michigan will be assessed only an administrative fee and a fee for biosolids that are  
land applied in the state of Michigan. The report is due 30 days after the end of the state  
fiscal year. By December 15 of each state fiscal year, the department shall determine the  
generation fee on a per dry ton basis by dividing the cumulative generation fee by the  
number of dry tons of biosolids applied to land or in derivatives applied to land in the  
state of Michigan in the immediately preceding state fiscal year. The department shall  
notify each biosolids generator and biosolids distributor of the generation fee on a per  
dry ton basis.  
(3) A generator or distributor that land-applied biosolids or a derivative to land  
within the state at any time during the previous state fiscal year shall report to the  
department the information required in R 323.2413(3) to (8), except R 323.2413(6)(b),  
(7)(b), and (8)(b), on or before October 30.  
(4) By January 31 of each state fiscal year, each biosolids generator or biosolids  
distributor shall pay its biosolids land application fee. The biosolids generator or  
biosolids distributor shall determine the amount of its biosolids land application fee by  
multiplying the number of dry tons of biosolids that it reported under subrule (2) of this  
rule by the generation fee and adding the administrative fee.  
(5) The department of environmental quality shall assess interest on all fee  
payments submitted under this rule after the due date. The permittee shall pay an  
additional amount equal to 0.75% of the payment due for each month or portion of a  
month that the payment remains past due. The failure by a person to pay a fee imposed by  
this rule in a timely manner is a violation of this part.  
Page 32  
(6) The biosolids land application fund is created in the state department of  
treasury. The department of environmental quality shall forward all fees collected under  
this rule to the state treasurer for deposit into the fund. The state treasurer may receive  
money or other assets from any source for deposit into the fund. The state treasurer  
shall direct the investment of the fund. The state treasurer shall credit to the fund interest  
and earnings from fund investments. The department of environmental quality shall  
carry an unexpended balance within the fund at the close of the state fiscal year  
forward to the following state fiscal year. The department of environmental quality shall  
ensure that the fund is allocated solely for the administration of this rule and sections  
3131 and 3133 of the act, including, but not limited to, education of the farmers,  
biosolids generators, biosolids distributors, and the general public about land application  
of biosolids and derivatives and the requirements of this rule and sections 3131 and  
3133 of the act. The director of the department may contract with a nonprofit  
educational organization to administer the educational components of this rule. The  
state department of treasury shall allocate 10% of the fund to the department of  
agriculture to provide persons involved in or affected by land application of biosolids  
or derivatives with education and technical assistance relating to land application of  
biosolids or derivatives.

R 323.2417 Procedure to determine annual whole biosolids application rate.  
Rule 2417. (1) A person who applies biosolids to the land shall use the following  
formula to determine the loading rate:  
Loading Rate Formula  
AP = PC x 0.002 x AR  
Where: AP = applied pollutant in pounds per acre.  
PC = pollutant concentration in milligrams per kilogram dry weight.  
0.002 = the factor to convert pollutant concentration to pounds per dry ton.  
AR = the biosolids application rate in dry tons per acre.  
(2) R 323.2409(4)(b) requires that the product of the concentration for each  
pollutant listed in table 4 of R 323.2409(5)(d) in biosolids sold or given away in a bag  
or other container for application to the land and the annual whole biosolids application  
rate (AWBAR) for the biosolids not cause the annual pollutant loading rate for the  
pollutant in table 4 to be exceeded. This rule contains the procedure used to determine  
the AWBAR for biosolids that do not cause the annual pollutant loading rates in table 4  
to be exceeded. The relationship between the annual pollutant-loading rate (APLR)  
for a pollutant and the annual whole biosolids application rate (AWBAR) for a  
biosolids is shown in the following equation:  
APLR = C x AWBAR X 0.001  
equation (1)  
Page 33  
Where: APLR = annual pollutant loading rate in kilograms per hectare per 365-day  
period.  
C = pollutant concentration in milligrams per kilogram of total solids (dry weight  
basis).  
AWBAR = annual whole biosolids application rate in metric tons per hectare per  
365-day period (dry weight basis).  
0.001 = a conversion factor.  
(3) To determine the AWBAR, equation (1) is rearranged into the following  
equation:  
AWBAR = APLR  
C x 0.001  
equation (2)  
(4) The procedure used to determine the AWBAR for biosolids is as follows:  
(a) Analyze a sample of the biosolids to determine the concentration for each of  
the pollutants in the biosolids listed in table 4 of R 323.2409(5)(d).  
(b) Using the pollutant concentrations from subdivision (a) of this subrule and the  
APLRs from table 4 of R 323.2409(5)(d), calculate an AWBAR for each pollutant using  
equation (2) in subrule (3) of this rule.  
(c) The AWBAR for the biosolids is the lowest AWBAR calculated in subdivision  
(b) of the subrule.

R 323.2418 Pathogen treatment processes.  
Rule 2418. (1) The process to significantly reduce pathogens (PSRP) is as follows:  
(a) Biosolids are agitated with air or oxygen to maintain aerobic conditions for  
a specific mean cell residence time at a specific temperature. Values for the mean cell  
residence time and temperature shall be between 40 days at 20 degrees Celsius and 60  
days at 15 degrees Celsius.  
(b) Biosolids are dried on sand beds or on paved or unpaved basins. The biosolids  
dry for a minimum of 3 months. During 2 of the 3 months, the ambient average daily  
temperature is above 0 degrees Celsius.  
(c) Biosolids are treated in the absence of air for a specific mean cell residence  
time at a specific temperature. Values for the mean cell residence time and temperature  
shall be between 15 days at 35 to 55 degrees Celsius and 60 days at 20 degrees Celsius.  
(d) Using the within-vessel, static aerated pile, or windrow composting method,  
the temperature of the biosolids is raised to 40 degrees Celsius or higher and remains at  
40 degrees Celsius or higher for 5 days. For 4 hours during the 5 days, the temperature  
in the compost pile exceeds 55 degrees Celsius.  
(e) Sufficient lime is added to the biosolids to raise the pH of the biosolids to 12  
after 2 hours of contact.  
(2) The processes to further reduce pathogens (PFRP) are as follows:  
(a) Using either the within-vessel composting method or the static aerated pile  
composting method, the temperature of the biosolids is maintained at 55 degrees Celsius  
or higher for 3 days. Using the windrow composting method, the temperature of the  
Page 34  
biosolids is maintained at 55 degrees or higher for 15 days or longer. During the period  
when the compost is maintained at 55 degrees or higher, there shall be a minimum of  
5 turnings of the windrow.  
(b) Biosolids are dried by direct or indirect contact with hot gases to reduce the  
moisture content of the biosolids to 10% or lower. Either the temperature of the  
biosolids particles is more than 80 degrees Celsius or the wet bulb temperature of the  
gas in contact with the biosolids as the biosolids leaves the dryer is more than 80  
degrees Celsius.  
(c) Liquid biosolids are heated to a temperature of 180 degrees Celsius or higher for  
30 minutes.  
(d) Liquid biosolids are agitated with air or oxygen to maintain aerobic conditions  
and the mean cell residence time of the biosolids is 10 days at 55 to 60 degrees Celsius.  
(e) Biosolids are irradiated with beta rays from an accelerator at dosages of at least  
1.0 megarad at room temperature (approximately 20 degrees Celsius).  
(f) Biosolids are irradiated with gamma rays from certain isotopes, such as 60Cobalt  
and 137Cesium, at dosages of at least 1.0 megarad at room temperature  
(approximately 20 degrees Celsius).  
(g) The temperature of the biosolids is maintained at 70 degrees Celsius or higher  
for 30 minutes or longer.
