NOTES TO APPENDIX C
It should be emphasized that because of the wide range of
						physical factors, no one value (of the few which can be incorporated in a
						standard) can relate health effects to contamination levels in all the diverse
						situations in which contamination is measured. Accordingly, standards for
						contamination levels must be used as guides (or decision levels). The above
						levels shall therefore be applied with the following guidance:
1. The levels are to be used as guides, and
					 in practice professional judgment should be used by the health physicist to
					 determine the acceptability of the actual contamination.
2. Although it is felt that the recommended
					 values should not result in a health hazard, good radiation protection practice
					 dictates that a reasonable effort be made to keep actual contamination levels
					 below these values.
3. Compliance
					 with contamination guides shall not be used as evidence that exposing persons
					 to internal or external sources of radiation is within the prescribed
					 standards. Biological sampling or whole body counting should be used to
					 ascertain internal doses.
4. For
					 release of material to the general public:
a.
					 A reasonable effort shall be made to minimize the contamination (i.e. the
					 application of additional decontamination procedures have little effect on the
					 contamination levels).
b. Surfaces
					 of premises or equipment likely to be contaminated that are inaccessible for
					 measurement shall be presumed to be contaminated in excess of the above limits
					 and not released.

Michigan Administrative Code › Department - Environmental Quality › Remediation and Redevelopment Division › Environmental Contamination Response Activity › CLEANUP CRITERIA REQUIREMENTS FOR RESPONSE ACTIVITY › Section R. 299.3 - Response activities; protection of public health, safety, welfare, and environment required; rules applicable to interim response actions designed to meet cleanup criteria; degree of cleanup; modification of cleanup category; aquifers; unacceptability of response activity plan

Current through Vol. 24-12, July 15, 2024
Rule 3.
(1) All
				  response activities shall be protective of the public health, safety, and
				  welfare and the environment. Applicable generic cleanup criteria established by
				  the department pursuant to section 20120a(1) and site specific cleanup criteria
				  approved by the department under section 20120a(2) and 20120b of the act and
				  these rules reflect the departments judgment, at the time the criteria are
				  established or approved by the department, about the numerical criteria
				  required to meet this protectiveness requirement, subject to the provisions of
				  R 299.4(3), R 299.28, and R 299.34(2).
(2) The rules in this part apply to interim
				  response activities that are designed to meet cleanup criteria. References in
				  this part to response activity also include those interim response
				  activities.
(3) The category of
				  land use-based remedial action under section 20120a(1) of the act or the
				  site-specific cleanup criteria identified under sections 20120a(2) and 20120b
				  of the act may be modified by the person proposing to conduct the response
				  activity that will result in modification during implementation or after
				  completion of a remedial action, if appropriate to the facility and if that
				  modification is accomplished in a manner that is consistent with the act and
				  these rules.
(4) If a revised land
				  use-based remedial action includes characteristics that are required to be
				  approved by the department, then the person implementing the change shall seek
				  department approval as required by part 201 of the act and these
				  rules.
(5) The horizontal and
				  vertical extent of hazardous substance concentrations in an aquifer above the
				  higher of either the concentration allowed by section 20120a(1)(a) or (10) of
				  the act, as applicable, shall not increase after the initiation of remedial
				  actions to address an aquifer, except as approved by the director as provided
				  in section 20118(5) and (6) of the act.
(6) All remedial actions that address the
				  remediation of an aquifer shall provide for removal of the hazardous substance
				  or substances from the aquifer, either through active remediation or as a
				  result of naturally occurring biological or chemical processes which can be
				  documented to occur at the facility, except as provided in section 20118(5) and
				  (6) of the act.
Michigan Administrative Code › Department - Environmental Quality › Remediation and Redevelopment Division › Environmental Contamination Response Activity › CLEANUP CRITERIA REQUIREMENTS FOR RESPONSE ACTIVITY › Section R. 299.4 - General requirements for application of cleanup criteria

Current through Vol. 24-12, July 15, 2024
Rule 4.
(1) All
				  cleanup criteria used in response activity undertaken under part 201 of the act
				  and these rules shall be based on best available information.
(2) The generic cleanup criteria developed by
				  the department using the algorithms presented in these rules are derived
				  primarily from data that reflect chronic toxicity endpoints. If a hazardous
				  substance has a more sensitive toxic effect than those associated with the
				  chronic toxicity data used to calculate a generic criterion, then a criterion
				  shall be developed to address the most sensitive effect. The generic cleanup
				  criteria established by the department shall be accepted as protective of the
				  most sensitive toxic effect in a given exposure pathway for the hazardous
				  substance in question.
(3) If the
				  department has not calculated a criterion for a hazardous substance for a given
				  exposure pathway, then the person proposing or implementing the response
				  activity shall supply the necessary data for the department to calculate a
				  criterion or establish a criterion under subrule (4) of this rule, unless the
				  department determines that a numerical criterion is not required to assure that
				  a given response activity will be protective.
(4) A generic or site-specific cleanup
				  criterion may be established by the department based on best professional
				  judgment instead of a calculation based on minimum toxicity data for a specific
				  hazardous substance when the minimum toxicity data are not available for that
				  hazardous substance, but data of sufficient quality are available to show that

Rule 6.
(1) Except
				  as provided in subrules (9), (10) and (11) of this rule, generic groundwater
				  cleanup criteria for the residential and nonresidential categories shall be the
				  values shown in table 1 of R 299.44. If a generic groundwater cleanup criterion
				  is higher than the flammability and explosivity screening level shown in table
				  1 of R 299.44, then the person proposing or implementing response activity
				  shall document whether additional response activity is required to protect
				  against the acute hazard.
(2)
				  Except as provided in subrules (9), (10), and (11) of this rule, generic soil
				  cleanup criteria for the residential category shall be the values shown in
				  table 2 of R 299.46. If soil concentrations are greater than
				  Csat, then the person proposing or implementing response
				  activity shall evaluate whether additional response activity is required to
				  control free-phase liquids or to protect against risks associated with
				  free-phase liquids that are not accounted for in development of the generic
				  criteria.
(3) Except as provided in
				  subrules (9), (10), and (11) of this rule, generic soil cleanup criteria for
				  the nonresidential category shall be the values shown in table 3 of R
				  299.48.
(4) The generic cleanup
				  criteria shown in R 299.44, R 299.46, and R 299.48 and identified under subrule
				  (12) of this rule may be used and known as risk-based screening levels for
				  corrective actions required under part 213 of the act.
(5) Generic cleanup criteria under R 299.44,
				  R 299.46, and R 299.48 are based on the target detection limit or background
				  concentration in the following cases:
(a) If
				  a calculated cleanup criterion is less than the target detection limit for that
				  hazardous substance in a given medium, then the target detection limit is the
				  cleanup criterion. Criteria to which this subdivision applies are designated
				  with a footnote in the criteria tables.
(b) A background concentration may be
				  substituted for a generic cleanup criterion when the background concentration
				  is higher than a criterion shown in R 299.44, R 299.46, or R 299.48.

Rule 9.
(1) If a
				  hazardous substance, singly or in combination with other hazardous substances
				  present at the facility, imparts adverse aesthetic characteristics to
				  groundwater in an aquifer, then the cleanup criterion shall be the secondary
				  maximum contaminant level, or, if there is no secondary maximum contaminant

				  concentration or the concentration below which appearance or other aesthetic
				  characteristics are not adversely affected. The criteria of this subrule shall
				  apply only when the level required by this subrule is less than the level
				  required by section 20120a(4) of the act. A taste or odor threshold
				  concentration or a concentration adversely affecting appearance shall be
				  determined according to methods approved by the United States environmental
				  protection agency.
(2) For the
				  purposes of this rule, the point of exposure shall be presumed to be any point
				  in the affected aquifer.
