Current through Vol. 24-23, January 1, 2025

Section R. 324.1401 - Definitions

Rule 1401. As used in these rules:

(a) "Adverse resource impact," "assessment tool," "cold-transitional river system," "cool river system," "site-specific review," "warm river system," "withdrawal," "zone A withdrawal," "zone B withdrawal," "zone C withdrawal," and "zone D withdrawal," have the same meanings as in section 32701 of the act.

(b) "Available water source" means a reasonably identifiable fresh water well used for human consumption for which the water well owner has given written consent for sampling and testing and to having the sample data made a part of the departments public records.

(c) "Chemical Abstracts Service (CAS) Number" means the unique identification number assigned to a chemical by the division of the American Chemical Society that is the globally recognized authority for information on chemical substances.

(d) "Chemical additive" means a product composed of 1 or more chemical constituents that is intentionally added to a primary carrier fluid to enhance the characteristics of hydraulic fracturing fluid.

(e) "Chemical constituent" means a discrete chemical with its own specific name or identity, such as a CAS number, that is contained in a chemical additive.

(f) "Chemical family" means a group of elements or compounds that have similar physical and chemical characteristics and have a common general name.

(g) "Flowback fluid" means hydraulic fracturing fluid and brine recovered from a well after completion of a hydraulic fracturing operation and before the conclusion of test production under R 324.606.

(h) "High volume hydraulic fracturing" means a hydraulic fracturing well completion operation that is intended to use a total volume of more than 100,000 gallons of primary carrier fluid. If the primary carrier fluid consists of a base fluid with 2 or more components, the volume shall be calculated by adding the volumes of the components. If 1 or more of the components is a gas at prevailing temperatures and pressures, the volume of that component or components shall be calculated in the liquid phase.

(i) "Hydraulic fracturing" means a well completion operation that involves pumping fluid and proppants into the target formation under pressure to create or propagate artificial fractures, or enhance natural fractures, for the purpose of improving the deliverability and production of hydrocarbons. Hydraulic fracturing does not include other stimulation completion techniques such as treatments that do not use proppants.

(j) "Hydraulic fracturing fluid" means fluid at a well site that is prepared for injection into a well to achieve a hydraulic fracturing operation, including primary carrier fluid and additives.

(k) "Large volume water withdrawal" means a water withdrawal intended to produce a cumulative total of over 100,000 gallons of water per day when averaged over a consecutive 30-day period.

(l) "Primary carrier fluid" means the base fluid, such as water, into which chemical additives are mixed to form the hydraulic fracturing fluid.

(m) "Proppant" means sand or any natural or man-made material that is used in a hydraulic fracturing completion to prop open the artificially created or enhanced fractures once the treatment is completed.

(n) "Trade secret" has the same meaning as defined in the uniform trade secrets act, 1998 PA 448, MCL 445.1901 to 445.1910.
