Sec. 13.
(a) This
				section contains the requirements for a biosolid to be classified either Class
				A or Class B with respect to pathogens.
(b) To be categorized as Class A, a biosolid
				must meet or exceed the following requirements:
(1) The pathogen requirements in subdivision
				(2) must be met either prior to, or at the same time as, the vector attraction
				reduction requirements in section 15(b)(1) through 15(b)(5), 15(b)(9), and
				15(b)(10) of this rule.
(2) The
				requirements in one (1) of the following alternatives:
(A) For Class A, Alternative 1, except for
				composting, the following:
(i) The density of
				fecal coliform in the biosolid, as determined by Part 9221 E* or Part 9222 D*,
				must be less than one thousand (1,000) most probable number (MPN) per gram of
				total solids.
(ii) The temperature
				of the biosolid that is used or disposed must be maintained at a specific value
				for a period of time as applicable in the following:
(AA) When the percent total solids of the
				biosolid is seven percent (7%) or higher, the temperature of the biosolid must
				be fifty (50) degrees Celsius or higher; the time period must be twenty (20)
				minutes or longer; and the temperature and time period must be determined using
				Equation 1 as follows, except when small particles of biosolid are heated by
				either warmed gases or an immiscible liquid: Equation 1:

Where: D = Time in days.
t = Temperature in degrees Celsius.
(BB) When the percent total solids of the
				biosolid is seven percent (7%) or higher and small particles of biosolid are
				heated by either warmed gases or an immiscible liquid, the temperature of the
				biosolid must be fifty (50) degrees Celsius or higher; the time period must be
				fifteen (15) seconds or longer; and the temperature and time period must be
				determined using Equation 1 in subitem (AA). (CC) When the percent total solids
				of the biosolid is less than seven percent (7%) and the time period is at least
				fifteen (15) seconds, but less than thirty (30) minutes, the temperature and
				time period must be determined using Equation 1 in subitem (AA).
(DD) When the percent total solids of the
				biosolid is less than seven percent (7%), the temperature of the biosolid is
				fifty (50) degrees Celsius or higher; and the time period is thirty (30)
				minutes or longer, the temperature and time period must be determined using
				Equation 2 as follows:
Equation 2:

Where: D = Time in days.
t = Temperature in degrees Celsius.
(B) For Class A,
				Alternative 2, the following:
(i) The density
				of fecal coliform in the biosolid, as determined by Part 9221 E* or Part 9222
				D*, must be less than one thousand (1,000) MPN per gram of total
				solids.
(ii) The pH of the biosolid
				must be raised to above 12 and shall remain above 12 for seventy-two (72)
				hours.
(iii) The temperature of the
				biosolid must be above fifty-two (52) degrees Celsius for twelve (12) hours or
				longer during the period that the pH of the biosolid is above 12.
(iv) At the end of the seventy-two (72) hour
				period during which the pH of the biosolid is above 12, the biosolid must be
				air dried to achieve a percent total solids in the biosolid greater than fifty
				percent (50%).
(C) For
				Class A, Alternative 3, the following:
(i)
				The density of fecal coliform in the biosolid, as determined by Part 9221 E* or
				Part 9222 D*, must be less than one thousand (1,000) MPN per gram of total
				solids.
(ii) Regarding enteric
				viruses, the following:
(AA) The biosolid must
				be analyzed prior to pathogen treatment to determine whether the biosolid
				contains enteric viruses using ASTM Designation: D 4994-89*.
(BB) When the density of enteric viruses in
				the biosolid prior to pathogen treatment is less than one (1) plaque-forming
				unit (PFU) per four (4) grams of total solids the biosolid is Class A with
				respect to enteric viruses until the next monitoring required by section 16 of
				this rule for the biosolid.
(CC)
				When the density of enteric viruses in the biosolid prior to pathogen treatment
				is equal to or greater than one (1) PFU per four (4) grams of total solids the
				biosolid is Class A with respect to enteric viruses when the density of enteric
				viruses in the biosolid after pathogen treatment is less than one (1) PFU per
				four (4) grams of total solids and when the values or ranges of values for the
				operating parameters for the pathogen treatment process that produces the
				biosolid that meets the enteric virus density requirement are
				documented.
(DD) After the enteric
				virus reduction in subitem (CC) is demonstrated for the pathogen treatment
				process, the biosolid continues to be Class A with respect to enteric viruses
				when the values for the pathogen treatment process operating parameters are
				consistent with the values or ranges of values documented in subitem
				(CC).
(iii) Regarding
				viable helminth ova, the following:
(AA) Prior
				to pathogen treatment the biosolid must be analyzed to determine whether the
				biosolid contains viable helminth ova using methods in EPA 600/
				1-87-014 *.
(BB) When the density of viable helminth ova
				in the biosolid prior to pathogen treatment is less than one (1) per four (4)
				grams of total solids the biosolid is Class A with respect to viable helminth
				ova until the next monitoring required by section 16 of this rule for the
				biosolid.
(CC) When the density of
				viable helminth ova in the biosolid prior to pathogen treatment is equal to or
				greater than one (1) per four (4) grams of total solids the biosolid is Class A
				with respect to viable helminth ova when the density of viable helminth ova in
				the biosolid after pathogen treatment is less than one (1) per four (4) grams
				of total solids and when the values or ranges of values for the operating
				parameters for the pathogen treatment process that produces the biosolid that
				meets the viable helminth ova density requirement are documented.
(DD) After the viable helminth ova reduction
				in subitem (CC) is demonstrated for the pathogen treatment process, the
				biosolid continues to be Class A with respect to viable helminth ova when the
				values for the pathogen treatment process operating parameters are consistent
				with the values or ranges of values documented in subitem (CC).
(D) For Class A,
				Alternative 4, the following:
(i) The density
				of fecal coliform in the biosolid, as determined by Part 9221 E* or Part 9222
				D*, must be less than one thousand (1,000) MPN per gram of total
				solids.
(ii) The density of enteric
				viruses in the biosolid must be less than one (1) PFU per four (4) grams of
				total solids.
(iii) The density of
				viable helminth ova in the biosolid must be less than one (1) per four (4)
				grams of total solids.
(E) For Class A, Alternative 5, the
				following:
(i) The density of fecal coliform
				in the biosolid, as determined by Part 9221 E* or Part 9222 D*, must be less
				than one thousand (1,000) MPN per gram of total solids.
(ii) Biosolid must be treated in one (1) of
				the processes to further reduce pathogens described in section 14(b) of this
				rule.
(F) For Class A,
				Alternative 6, the following:
(i) The density
				of fecal coliform in the biosolid, as determined by Part 9221 E* or Part 9222
				D*, must be less than one thousand (1,000) MPN per gram of total
				solids.
(ii) A biosolid must be
				treated in a process that is equivalent to a process to further reduce
				pathogens as determined by the commissioner on the recommendation of EPA.
