(1) The
				department may, after notice and opportunity for public participation and
				review by affected states and the United States environmental protection agency
				consistent with
				R
				336.1214(3), (4), and (6), issue a
				general renewable operating permit covering numerous similar stationary
				sources. Any general renewable operating permit shall comply with all
				requirements applicable to other renewable operating permits and shall identify
				criteria by which stationary sources may qualify for the general renewable
				operating permit. The department shall grant the terms and conditions of the
				general renewable operating permit to stationary sources that qualify.
				Notwithstanding the permit shield provisions of
				R
				336.1213(6), the owner or operator of
				a stationary source shall be subject to enforcement action for operation
				without a renewable operating permit if the department later determines that
				the stationary source does not qualify for the general renewable operating
				permit. The department shall not authorize general renewable operating permits
				for affected sources under the acid rain program, unless otherwise provided in
				regulations promulgated under title IV of the clean air act.
(2) The owner or operator of a stationary
				source that meets the criteria specified in
				R 336.1211 and who would qualify for
				a general renewable operating permit issued by the department pursuant to
				subrule (1) of this rule, shall either apply to the department for coverage
				under the terms of the general renewable operating permit or apply for a
				renewable operating permit consistent with
				R
				336.1210. The department may, in the general renewable
				operating permit, provide for applications that deviate from the administrative
				completeness requirements of section 5507 of the act, if the applications meet
				the requirements of title V of the clean air act and include all information
				necessary to determine qualification for, and to assure compliance with, the
				general renewable operating permit. Without repeating the public participation
				and review by affected states and the United States environmental protection
				agency required under
				R
				336.1214(3), (4), and (6), the
				department may grant a request by a person for authorization to operate under a
				general renewable operating permit, but the granting shall not be a final
				permit action for purposes of judicial review.

				than the initial threshold screening level or the initial risk screening level,
				or both, except as provided in subrules (2) and (3) of this rule and in
				R 336.1226.
(2) As an alternative to complying with the
				initial risk screening level in subrule (1) of this rule, a person may instead
				demonstrate compliance with the secondary risk screening level. For the purpose
				of complying with the secondary risk screening level, the total allowable
				emissions of the carcinogen from the proposed new or modified emission unit or
				units and all existing emission units at the stationary source shall not result
				in a maximum ambient impact that is more than the secondary risk screening
				level.
(3) If the ambient impacts
				of a carcinogen occur on industrial property or public roadways, as an
				alternative to complying with subrule (1) or (2) of this rule, a person may
				instead demonstrate compliance with either of the following provisions:
(a) The maximum allowable emission rate of
				the carcinogen from the proposed new or modified emission unit or units results
				in ambient impacts that meet both of the following requirements:
(i) The maximum ambient impact on industrial
				property or public roadways is less than or equal to the initial risk screening
				level multiplied by a factor of 10.
(ii) The maximum ambient impact on all
				property that is not industrial or a public roadway is less than or equal to
				the initial risk screening level.

Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 2 - AIR USE APPROVAL › Section R. 336.1228 - Requirement for lower emission rate than required by best available control technology for toxics (T-BACT) and health-based screening levels

Current through Vol. 24-12, July 15, 2024
Rule 228.
(1) The
				department may determine, on a case-by-case basis, that the maximum allowable
				emission rate determined in
				R 336.1224(1) or
				R 336.1225(1) to
				(3) does not provide adequate protection of
				human health or the environment. In this case, the department shall establish a
				maximum allowable emission rate considering relevant scientific information,
				such as exposure from routes other than direct inhalation, synergistic or
				additive effects from other toxic air contaminants, and effects on the
				environment. In performing these evaluations and determinations, the department
				shall utilize relevant environmental data, land use, and exposure scenarios,
				and reasonably anticipated environmental impacts and exposures from the
				proposed new or modified emission unit or units.
(2) The director may determine on a
				case-by-case basis that an emission rate limitation is needed for a non-toxic
				air contaminant for which there is no national ambient air quality standard in
				order to ensure that air emissions do not cause injurious effects to human
				health. The director shall make this case-by-case determination subsequent to a
				presentation by the air quality division and the permit applicant that utilizes
				relevant environmental data, land use, and exposure scenarios, and reasonably
				anticipated environmental impacts and exposures from the proposed new or
				modified emission unit or units. The department shall establish this emission
				rate consistent with the provisions of
				R 336.1225,
				R 336.1227, and
				R 336.1229 or any other methodology

Current through Vol. 24-12, July 15, 2024
Rule 231.
(1) The
				initial risk screening level (IRSL) and the secondary risk screening level
				(SRSL) shall be determined as follows:
Where: Inhalation unit risk = Additional lifetime cancer risk
				  occurring in a population in which all individuals are exposed continuously for
				  life to a concentration of 1 microgram per cubic meter of the chemical in the

1 x 10-6 = An upper bound lifetime
				  cancer risk of 1 in 1,000,000.
1 x 10-5 =An upper bound lifetime
				  cancer risk of 1 in 100,000.
(2) The following provisions apply to
				derivation of the inhalation unit risk:
(a)
				The inhalation unit risk value determined by the United States environmental
				protection agency
(b) If the
				inhalation unit risk value has not been determined by the United States
				environmental protection agency, then the inhalation unit risk value shall be
				determined by the department according to the United States environmental

Current through Vol. 24-12, July 15, 2024
Rule 233.
(1) An
				ITSL based on acute data shall be determined by either of the following:
From short-term studies, as follow:

				  Here To View Image
Where:
POD = Point of Departure
UFh = a value from 1 to 10 for average human to sensitive
				  human extrapolation
UFA = a value from 1 to 10 for animal
				  to human extrapolation
UFL = a value from 1 to 10 for LOAEL
				  to NOAEL extrapolation
AT = Averaging time of 1, 8 or 24 hours
The POD is defined as the human equivalent concentration of
				  any of the following:
NOAEL = no observed adverse effect level
LOAEL = lowest observed adverse effect level
BMDL = 95% lower confidence limit on the benchmark dose
				  (BMD)
BMCL = 95% lower confidence limit on the benchmark
				  concentration (BMC)
The BMD or BMC value is derived according to the United
				  States environmental protection agency benchmark dose technical guidance,
				  adopted by reference in
				  R
				  336.1902. "Human equivalent concentration" is defined
				  as an exposure concentration for humans that has been adjusted for dosimetric
				  differences between experimental animal species and humans to be equivalent to
				  the exposure concentration associated with observed effects in the experimental
				  animal species. If occupational human exposures are used for extrapolation, the
				  human equivalent concentration represents the equivalent human exposure
				  concentration adjusted to a continuous basis.
(b) The ITSL may be determined on a
				case-by-case basis using a POD from repeated dose studies using any alternative
				methodology to assess acute health effects that can be demonstrated to the
				department to be more appropriate based on toxicological grounds and that is
				supported by the scientific data.
