DEPARTMENT OF ENVIRONMENT, GREAT LAKES, AND ENERGY  
REMEDIATION AND REDEVELOPMENT DIVISION  
ENVIRONMENTAL CONTAMINATION RESPONSE ACTIVITY  
Filed with the secretary of state on February 15, 2022  
These rules take effect immediately upon filing with the secretary of state unless adopted  
under section 33, 44, or 45a(9) of the administrative procedures act of 1969, 1969 PA  
306, MCL 24.233, 24.244, or 24.245a. Rules adopted under these sections become  
effective 7 days after filing with the secretary of state.  
(By authority conferred on the director of the department of environment, Great Lakes,  
and energy by sections 20104, and 20120a of the natural resources and environmental  
protection act, 1994 PA 451, MCL 324.20104 and 324.20120a)  
R 299.44 of the Michigan Administrative Code is amended, as follows:  
CLEANUP CRITERIA REQUIREMENTS FOR RESPONSE ACTIVITY  
R 299.44 Generic groundwater cleanup criteria.  
Rule 44. The generic groundwater cleanup criteria for all categories are shown in table 1  
and table 1a.

TABLE 1. GROUNDWATER: RESIDENTIAL AND NONRESIDENTIAL  
PART 201 GENERIC CLEANUP CRITERIA AND SCREENING LEVELS  
All criteria, unless otherwise noted, are expressed in units of parts per billion (ppb). One ppb is equivalent to 1 microgram per liter (ug/L). Criteria with 6 or more digits are  
expressed in scientific notation. For example, 200,000 is presented as 2.0E+5. A footnote is designated by a letter in parentheses and is explained in the footnote pages that  
follow the criteria tables. When the risk-based criterion is less than the target detection limit (TDL), the TDL is listed as the criterion (§324.20120a(10)). In these cases, 2 numbers  
are present in the cell. The first number is the criterion (i.e., TDL), and the second number is the risk-based or solubility value, whichever is lower.

TABLE 1. GROUNDWATER: RESIDENTIAL AND NONRESIDENTIAL  
PART 201 GENERIC CLEANUP CRITERIA AND SCREENING LEVELS;  
All criteria, unless otherwise noted, are expressed in units of parts per billion (ppb). One ppb is equivalent to 1microgram per liter (ug/L). Criteria with 6 or more digits are  
expressed in scientific notation. For example, 200,000 is presented as 2.0E+5. A footnote is designated by a letter in parentheses and is explained in the footnote pages that  
follow the criteria tables. When the risk-based criterion is less than the target detection limit (TDL), the TDL is listed as the criterion (§324.20120a(10)). In these cases, 2 numbers  
are present in the cell. The first number is the criterion (i.e., TDL), and the second number is the risk-based or solubility value, whichever is lower.

TABLE 1. GROUNDWATER: RESIDENTIAL AND NONRESIDENTIAL  
PART 201 GENERIC CLEANUP CRITERIA AND SCREENING LEVELS;  
All criteria, unless otherwise noted, are expressed in units of parts per billion (ppb). One ppb is equivalent to 1 microgram per liter (ug/L). Criteria with 6 or more digits are  
expressed in scientific notation. For example, 200,000 is presented as 2.0E+5. A footnote is designated by a letter in parentheses and is explained in the footnote pages that  
follow the criteria tables. When the risk-based criterion is less than the target detection limit (TDL), the TDL is listed as the criterion (§324.20120a(10)). In these cases, 2 numbers  
are present in the cell. The first number is the criterion (i.e., TDL), and the second number is the risk-based or solubility value, whichever is lower.
