1. (1) In this Regulation, “CAES” means compressed air energy storage; “CAES project” means a CAES project in a porous rock reservoir or a CAES project in a salt cavern; “CAES project in a porous rock reservoir” means a type of CAES project described in paragraph 2 of subsection 2 (1); “CAES project in a salt cavern” mean a type of CAES project described in paragraph 1 of subsection 2 (1); “completion date” means the date on which a well is completed for regular production of oil or gas; “development well” means a well that is drilled for the purpose of producing from or extending a pool of oil or gas into which another well has already been drilled; “drill” means to use any method to bore or deepen a well; “exploratory well” means a well that is drilled for the purpose of discovering a pool of oil or gas; “pinnacle structure” means a three dimensional geological feature made up entirely of carbonate sedimentary rock of Silurian age that, (a)  is located underground, (b)  is composed of the layers of rock that make up the group of geological formations identified as the Lockport Group, as that group is described by F.R. Brunton and C. Brintnell in their report entitled “Early Silurian Sequence Stratigraphy and Geological Controls on Karstic Bedrock Groundwater-Flow Zones, Niagara Escarpment Region and the Subsurface of Southwestern Ontario: Ontario Geological Survey, Groundwater Resources Study 13”, dated 2020, published by Ontario’s Queen’s Printer and available on a website maintained by the government of Ontario, and (c)  forms an isolated geologic structure, in a shape similar to a mesa or butte; “pooled spacing unit” means a spacing unit in which all the various oil and gas interests have been pooled; “pooling” means the joining or combining of all the various oil and gas interests within a spacing unit for the purpose of drilling and subsequently producing a well; “porous rock reservoir” means the porous rock contained in a pinnacle structure or in two or more connected pinnacle structures and includes any porous rock adjacent to the pinnacle structures that shares permeability with the pinnacle structures; “private well” means, (a)  an unplugged well drilled for the purpose of oil or gas exploration or production on land of which the operator owns both the surface and mineral rights, and (b)  if oil or gas is produced from the well, the oil or gas, (i)  is for the operator’s private use, (ii)  is not used in relation to a business or commercial enterprise, and (iii)  is not sold by the operator; “Provincial Standards for CAES in Salt Caverns” means the standards set out in the document entitled “Provincial Standards for Compressed Air Energy Storage in Salt Caverns: Applications and Operations” published by the Ministry and available on a website maintained by the Government of Ontario, as that document is amended from time to time; “Provincial Standards for Oil, Gas and Salt Resources” means the standards set out in the document entitled “Oil, Gas and Salt Resources of Ontario, Provincial Operating Standards”, published by the Ministry and available on a website of the Government of Ontario, as that document is amended from time to time; “royalty interest” means the interest of an owner of oil or gas rights or the owner’s interest in the proceeds from the sale of the oil or gas in a situation where the owner has none of the cost of producing the oil or gas; “spud”, with respect to a well, means the commencement of actual drilling of the well’s surface casing hole using a cable tool or rotary drilling rig, but does not include activities to prepare a site for drilling the well, including installing a conductor pipe; “surface area” means, with respect to a CAES project in a porous rock reservoir, the surface area for the CAES project set out on a map that is attached to a licence or permit issued with respect to a well associated with the CAES project and available to the public in accordance with subsection (2) and that includes, (a)  all works, including wells used for the purposes of the CAES project in a porous rock reservoir, (b)  the area on the surface that corresponds to the furthest lateral extent of the porous rock reservoir underground, (c)  any area relating to the reservoir that was previously unitized by a voluntary agreement with which the Minister agreed or by an order made under the Act for the purposes of oil or gas production, and (d)  areas adjacent to the areas described in clauses (a) to (c) that are reasonably necessary to protect the porous rock reservoir from drilling and subsurface activities, other than those that are part of the CAES project; “target area” means the area within a spacing unit that is allocated for drilling a well; “TD date” means the date when the drilling of a well reaches the total depth of the well; “tract”, except in sections 14 and 15, (a)  in the case of a standard 81 hectare lot, means a unit of area obtained by dividing the lot into eight equal rectangular areas of 10.12 hectares more or less and described by number in the manner set forth in the Schedule, (b)  in the case of a standard 40.5 hectare lot, means a unit of area obtained by dividing the lot into four equal rectangular areas of 10.12 hectares more or less and described by number in the manner set forth in the Schedule, and (c)  in the case of a lot that is not a standard 81 hectare or 40.5 hectare lot, means a unit of area obtained by dividing the lot into such equal areas as are approved by the Minister; “waste”, in addition to its meaning as ordinarily understood in the oil and gas industry, includes, (a)  inefficient, excessive or improper use or dissipation of reservoir energy, (b)  locating, spacing, drilling, equipping, operating or producing of any well in a manner that causes or might cause a reduction in the quantity of oil or gas ultimately and economically recoverable from any pool, (c)  inefficient storage of oil or gas, whether on the surface or underground, and (d)  locating, spacing, drilling, equipping, operating or producing a well in a manner that causes or might cause unnecessary or excessive surface or subsurface loss of oil or gas whether the oil or gas is being produced or stored; “working interest” means the operating interest under an oil and gas lease that is subject to all the costs of drilling, completion and operation under the lease.

(2) A copy of the map referred to in the definition of “surface area” in subsection 1 (1) that sets out the surface area of a CAES project in a porous rock reservoir, shall be made available to the public by the Ministry by posting it on a website maintained by the government of Ontario once a licence or permit with respect to a well that is part of the CAES project is granted.
