(e) "Stored product" means any substance except liquid hydrocarbons, liquified petroleum gas, or dry natural gas which is injected into an underground storage cavity with the intent to remove the substance from the underground storage cavity at some future time. Stored product does not include water or other solvents injected into a cavity or well during solution mining to form an artificial brine.

(g) "Substantially modify" means any of the following: (i) To permanently reroute above-ground facility piping outside of an existing secondary containment area. (ii) To add vessels at a surface facility or well having no secondary containment on the effective date of these rules. (iii) To add a vessel at a surface facility having secondary containment when the addition of the vessel would increase the total volume of the vessels to more than the capacity of the diked area required in R 299.2446(c). Substantially modify does not include routine maintenance or emergency repairs at a wellhead or surface facility. (h) "Surface casing" means the casing string or strings used primarily for protecting fresh water or mineralized water resources from potential contamination during the drilling and operation of a well. (i) "Surface facility" means the area in the vicinity of a well subject to this part where produced brine, waste products or stored products are held temporarily before transportation, disposal, or storage, and the surface equipment necessary for handling, disposing, or storing the liquids. Surface facility does not include any of the following: (i) Surface equipment subject to a permit under Part 111 of the act. (ii) Surface equipment within the perimeter of a manufacturing plant if the surface equipment is subject to secondary containment and spill response and reporting requirements under another part of the act. (iii) A pipeline connecting a well directly to a manufacturing plant. (iv) A well annulus monitoring system. (j) "Surface water" means a body of water, and the associated sediments, which has a top surface that is exposed to the atmosphere and which is not solely for wastewater conveyance, treatment, or control. Surface water may be any of the following: (i) A Great Lake or its connecting waters. (ii) An inland lake or pond. (iii) A river or stream, including intermittent streams. (iv) An impoundment.

(ii) Contains a sufficient quantity of groundwater to supply a public or private water system; and includes either of the following: (A) Currently supplies drinking water for human consumption. (B) Contains fewer than 11,000 milligrams per liter total dissolved solids. (l) "Well completion" means the time when a well has been tested and found to be incapable of being put to the use for which it was intended and has been plugged or has been found capable of being put to the use for which it was intended or when the well has been equipped to perform the service for which it was intended. (m) "Well completion operations" means work performed in a well, after the well has been drilled to its permitted depth and the innermost string of casing has been set, including perforating, artificial stimulation, and production testing. (n) "Well location" means the surface location of a well. (o) "Zoned residential" means a geographic area that was zoned by a local unit of government before the effective date of these rules, as an area designated principally for permanent or recreational residences.
