Michigan Administrative Code › Department - Environmental Quality › Oil, Gas & Minerals Division › Oil and Gas Operations › Part 14 - HIGH VOLUME HYDRAULIC FRACTURING › Section R. 324.1401 - Definitions

Current through Vol. 24-12, July 15, 2024
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.
