     Sec. 20120a. (1) The department may establish cleanup criteria

and approve of remedial actions in the categories listed in this

subsection. The cleanup category proposed shall be the option of

the person proposing the remedial action, subject to department

approval, considering the appropriateness of the categorical

criteria to the facility. The categories are as follows:

     (a) Residential.

     (b) Commercial.

     (c) Recreational.

     (d) Industrial.

     (e) Other land use based categories established by the

department.

     (f) Limited residential.

     (g) Limited commercial.

     (h) Limited recreational.

     (i) Limited industrial.

     (j) Other limited categories established by the department.

     (2) The department may approve a remedial action plan based on

site specific criteria that satisfy the applicable requirements of

this part and the rules promulgated under this part. The department

shall utilize only reasonable and relevant exposure pathways in

determining the adequacy of a site specific criterion.

Additionally, the department may approve a remedial action plan for

a designated area-wide zone encompassing more than 1 facility, and

may consolidate remedial actions for more than 1 facility. The

department shall incorporate into a remedial action plan area-wide

or site-specific cleanup criteria derived from peer-reviewed

bioavailability studies, peer-reviewed site-specific human exposure

data, and any other peer-reviewed scientifically based risk

assessment studies that are available and relevant.

     (3) The department shall develop cleanup criteria pursuant to

subsection (1) based on generic human health risk assessment

assumptions determined by the department to appropriately

characterize patterns of human exposure associated with certain

land uses. The department shall utilize only reasonable and

relevant exposure pathways in determining these assumptions. The

department may prescribe more than 1 generic set of exposure

assumptions within each category described in subsection (1). If

the department prescribes more than 1 generic set of exposure

assumptions within a category, each set of exposure assumptions

creates a subcategory within a category described in subsection

(1). The department shall specify site characteristics that

determine the applicability of criteria derived for these

categories or subcategories.

     (4) If a hazardous substance poses a carcinogenic risk to

humans, the cleanup criteria derived for cancer risk under this

section shall be the 95% upper bound on the calculated risk of 1

additional cancer above the background cancer rate per 100,000

individuals using the generic set of exposure assumptions

established under subsection (3) for the appropriate category or

subcategory. If the hazardous substance poses a risk of an adverse

health effect other than cancer, cleanup criteria shall be derived

using appropriate human health risk assessment methods for that

adverse health effect and the generic set of exposure assumptions

established under subsection (3) for the appropriate category or

subcategory. A hazard quotient of 1.0 shall be used to derive

noncancer cleanup criteria. For the noncarcinogenic effects of a

hazardous substance present in soils, the intake shall be assumed

to be 100% of the protective level, unless compound and site-

specific data are available to demonstrate that a different source

contribution is appropriate. If a hazardous substance poses a risk

of both cancer and 1 or more adverse health effects other than

cancer, cleanup criteria shall be derived under this section for

the most sensitive effect.

     (5) If a cleanup criterion derived under subsection (4) for

groundwater in an aquifer differs from either: (a) the state

drinking water standard established pursuant to section 5 of the

safe drinking water act,  Act No. 399 of the Public Acts of 1976,

being section 325.1005 of the Michigan Compiled Laws 1976 PA 399,

MCL 325.1005, or (b) criteria for adverse aesthetic characteristics

derived pursuant to R 299.5709 of the Michigan administrative code,

the cleanup criterion shall be the more stringent of (a) or (b)

unless the department determines that compliance with this rule is

not necessary because the use of the aquifer is reliably restricted

pursuant to section 20120b(4) or (5).

     (6) The department shall not approve of a remedial action plan

in categories set forth in subsection (1)(b) to (j), unless the

person proposing the plan documents that the current zoning of the

property is consistent with the categorical criteria being

proposed, or that the governing zoning authority intends to change

the zoning designation so that the proposed criteria are consistent

with the new zoning designation, or the current property use is a

legal nonconforming use. The department shall not grant final

approval for a remedial action plan that relies on a change in

zoning designation until a final determination of that zoning

change has been made by the local unit of government. The

department may approve of a remedial action that achieves

categorical criteria that is based on greater exposure potential

than the criteria applicable to current zoning. In addition, the

remedial action plan shall include documentation that the current

property use is consistent with the current zoning or is a legal

nonconforming use. Abandoned or inactive property shall be

considered on the basis of zoning classifications as described

above.

     (7) Cleanup criteria from 1 or more categories in subsection

(1) may be applied at a facility, if all relevant requirements are

satisfied for application of a pertinent criterion.

     (8) Except as provided in subsection (4) and subsections (9)

to (13), compliance with the residential category in subsection

(1)(a) shall be based on  R 299.5709 through R 299.5711(4), R

299.5711(6) through R 299.5715 and R 299.5727 of the Michigan

administrative code. R 299.5711(5), R 299.5723, and R 299.5725 of

the Michigan administrative code shall not apply for calculations

of residential criteria under subsection (1)(a)  R 299.5706a to R

299.5710, R 299.5714, R 299.5718, and R 299.5722 to R 299.5726 of

the Michigan administrative code.

     (9) The need for soil remediation to protect an aquifer from

hazardous substances in soil shall be determined by  R 299.5711(2)

R 299.5720 of the Michigan administrative code, considering the

vulnerability of the aquifer or aquifers potentially affected if

the soil remains at the facility. Migration of hazardous substances

in soil to an aquifer is a pertinent pathway if appropriate based

on consideration of site specific factors.

     (10) The department may establish cleanup criteria for a

hazardous substance using a biologically based model developed or

identified as appropriate by the United States environmental

protection agency if the department determines all of the

following:

     (a) That application of the model results in a criterion that

more accurately reflects the risk posed.

     (b) That data of sufficient quantity and quality are available

for a specified hazardous substance to allow the scientifically

valid application of the model.

     (c) The United States environmental protection agency has

determined that application of the model is appropriate for the

hazardous substance in question.

     (11) If the cleanup criterion for a hazardous substance

determined by R 299.5707 of the Michigan administrative code is

greater than a cleanup criterion developed for a category pursuant

to subsection (1), the criterion determined pursuant to R 299.5707

of the Michigan administrative code shall be the cleanup criterion

for that hazardous substance in that category.

     (12) In determining the adequacy of a land-use based response

activity to address sites contaminated by polychlorinated

biphenyls, the department shall not require response activity in

addition to that which is subject to and complies with applicable

federal regulations and policies that implement the toxic

substances control act,  Public Law 94-469,  15  U.S.C. USC 2601

to  2629, 2641 to 2656, 2661 to 2671, and 2681 to  2692.

     (13) Response activity to address the release of

uncontaminated mineral oil satisfies R 299.5709 for groundwater or

R 299.5711  R 299.5720 for soil under the Michigan administrative

code if all visible traces of mineral oil are removed from

groundwater and soil.

     (14) Approval by the department of a remedial action plan

based on 1 or more categorical standard in subsection (1)(a) to (e)

shall be granted only if the pertinent criteria are satisfied in

the affected media. The department shall approve the use of

probabilistic or statistical methods or other scientific methods of

evaluating environmental data when determining compliance with a

pertinent cleanup criterion if the methods are determined by the

department to be reliable, to be scientifically valid, and to best

represent actual site conditions and exposure potential.

     (15) If a remedial action allows for venting groundwater, the

discharge shall comply with requirements of part 31, and the rules

promulgated under that part or an alternative method established by

rule. If the discharge of venting groundwater is provided for in a

remedial action plan that is approved by the department, a permit

for the discharge is not required. As used in this subsection,

"venting groundwater" means groundwater that is entering a surface

water of the state from a facility.

     (16) A remedial action plan shall provide response activity to

meet the residential categorical criteria, or provide for

acceptable land use or resource use restrictions pursuant to

section 20120b.

     (17) A remedial action plan that relies on categorical cleanup

criteria developed pursuant to subsection (1) shall also consider

other factors necessary to protect the public health, safety, and

welfare, and the environment as specified by the department, if the

department determines based on data and existing information that

such considerations are relevant to a specific facility. These

factors include, but are not limited to, the protection of surface

water quality and consideration of ecological risks if pertinent to

the facility based on the requirements of  R 299.5717  R 299.5728

of the Michigan administrative code.

     (18) The department shall annually evaluate and revise, if

appropriate, the cleanup criteria derived under this section. The

evaluation shall incorporate knowledge gained through research and

studies in the areas of fate and transport and risk assessment. The

department shall prepare and submit to the legislature a report

detailing revisions made to cleanup criteria under this section.
