Sec. 15.
(a) One (1)
				of the vector attraction reduction requirements in subsection (b) or an
				equivalent vector attraction reduction method as approved by the commissioner
				on the recommendation of the U. S. EPA must be met when biosolid is applied to
				any land application site.
(b) The
				following is a list of alternative vector attraction reduction requirements for
				a biosolid applied to the land:
(1) The mass
				of volatile solids in the biosolid is reduced by a minimum of thirty-eight
				percent (38%) as determined using EPA-625/R-92/013*.
(2) When the thirty-eight percent (38%)
				volatile solids reduction requirement in subdivision (1) cannot be met for an
				anaerobically digested biosolid, vector attraction reduction is demonstrated by
				digesting a portion of the previously digested biosolid anaerobically in the
				laboratory in a bench-scale unit for forty (40) additional days at a
				temperature between thirty degrees Celsius (30 °C) and thirty-seven degrees
				Celsius (37 °C). When, at the end of the forty (40) days, the volatile
				solids in the biosolid at the beginning of that period is reduced by less than
				seventeen percent (17%), vector attraction reduction is achieved.
(3) When the thirty-eight percent (38%)
				volatile solids reduction requirement in subdivision (1) cannot be met for an
				aerobically digested biosolid, vector attraction reduction is demonstrated by
				digesting a portion of the previously digested biosolid that has a percent
				total solids of two percent (2%) or less aerobically in the laboratory in a
				bench-scale unit for thirty (30) additional days at twenty degrees Celsius (20
				°C). When, at the end of the thirty (30) days, the volatile solids in the
				biosolid at the beginning of that period is reduced by less than fifteen
				percent (15%), vector attraction reduction is achieved.
(4) The specific oxygen uptake rate (SOUR) as
				determined using Part 2710 B* for a biosolid treated in an aerobic process is
				equal to or less than one and one-half (1.5) milligrams of oxygen per hour per
				gram of total solids at a temperature of twenty degrees Celsius (20
				°C).
(5) A biosolid is treated
				in an aerobic process for fourteen (14) days or longer. During that time, the
				temperature of the biosolid must be higher than forty degrees Celsius (40
				°C) and the average temperature of the biosolid must be higher than
				forty-five degrees Celsius (45 °C).
(6) The pH of a biosolid is raised to 12 or
				higher by alkali addition and, without the addition of more alkali, must remain
				at 12 or higher for two (2) hours and then at 11.5 or higher at the time the
				biosolid is applied to the land or distributed in a marketing and distribution
				program under 327 IAC 6.1-5.
(7)
				The percent total solids of a biosolid that does not contain unstabilized
				solids generated in a primary wastewater treatment process is equal to or
				greater than seventy-five percent (75%) at the time the biosolid is applied to
				the land or distributed in a marketing and distribution program under 327 IAC
				6.1-5.
(8) The percent total solids
				of a biosolid that contains unstabilized solids generated in a primary
				wastewater treatment process is equal to or greater than ninety percent (90%)
				at the time the biosolid is applied to the land or distributed in a marketing
				and distribution program under 327 IAC 6.1-5.
(9) A biosolid injected below the surface of
				the land must:
(A) have no significant amount
				of the biosolid present on the land surface within one (1) hour after the
				biosolid is injected; and
(B) when
				the biosolid is Class A under section 13(b) of this rule, with respect to
				pathogens, be injected below the land surface within eight (8) hours after
				being discharged from the pathogen treatment process.
(10) A biosolid applied to the land surface
				must:
(A) unless otherwise approved by the
				commissioner, be incorporated into the soil within six (6) hours after
				application to or placement on the land; and
(B) when a biosolid is Class A under section
				13(b) of this rule, with respect to pathogens, must be applied to or placed on
				the land within eight (8) hours after being discharged from the pathogen
				treatment process.
