Terms Used In Michigan Laws 324.21303
- Air: means ambient or indoor air at the point of exposure. See Michigan Laws 324.21302
- Capillary fringe: means the portion of the aquifer above an unconfined saturated zone in which groundwater is drawn upward by capillary force and can include the presence of LNAPL. See Michigan Laws 324.21302
- Commission: means the commission of natural resources. See Michigan Laws 324.301
- contaminated: means the presence of a regulated substance in soil, surface water, or groundwater or air that has been released from an underground storage tank system at a concentration exceeding the level set forth in the RCBA tier I screening levels established under section 20120a(1)(a) and (b). See Michigan Laws 324.21302
- Corrective action: means the investigation, assessment, cleanup, removal, containment, isolation, treatment, or monitoring of regulated substances released into the environment from an underground storage tank system that is necessary under this part to prevent, minimize, or mitigate injury to the public health, safety, or welfare, the environment, or natural resources. See Michigan Laws 324.21302
- Department: means the director of the department of natural resources or his or her designee to whom the director delegates a power or duty by written instrument. See Michigan Laws 324.301
- DNAPL: means a dense nonaqueous-phase liquid with a specific gravity greater than 1 and composed of 1 or more organic compounds that are immiscible or sparingly soluble in water. See Michigan Laws 324.21302
- Equitable: Pertaining to civil suits in "equity" rather than in "law." In English legal history, the courts of "law" could order the payment of damages and could afford no other remedy. See damages. A separate court of "equity" could order someone to do something or to cease to do something. See, e.g., injunction. In American jurisprudence, the federal courts have both legal and equitable power, but the distinction is still an important one. For example, a trial by jury is normally available in "law" cases but not in "equity" cases. Source: U.S. Courts
