Consolidation Period: From May 18, 2012 to the .
No amendments.
This Regulation is made in English only.
Definitions
1. In this Regulation,
鈥済round source heat pump鈥 means a system that is designed to heat and cool a building or structure by using a heat-transfer fluid to exchange heat with the ground or ground water;
鈥渉azardous gas鈥 means a gas or mixture of gases that,
(a) contains hydrocarbons (including methane), hydrogen sulphide or both,
(b) originates from the natural environment, and
(c) is present in an atmospheric concentration that may be explosive or flammable, may cause asphyxia or is otherwise hazardous;
鈥渓icensed engineering practitioner鈥 means a person who holds a licence, limited licence or temporary licence under the Professional Engineers Act;
鈥減rofessional geoscientist鈥 means a person who holds a certificate of registration under the Professional Geoscientists Act, 2000 and is a practising member, temporary member or limited member of the Association of Professional Geoscientists of 澳门永利;
鈥渧ertical closed loop ground source heat pump鈥 means a ground source heat pump that uses a continuous, sealed, underground heat exchanger consisting of subsurface tubing through which the heat-transfer fluid passes. O.聽Reg. 98/12, s.聽1.
Exemption, exceptions and transition
2. (1) The use, operation, construction, alteration, extension and replacement of a ground source heat pump is exempted from section 9 of the Act, except for the following:
1. The use, operation, construction, alteration, extension and replacement of a ground source heat pump that uses methanol as a heat-transfer fluid.
2. The construction, alteration, extension and replacement of the portion of a vertical closed loop ground source heat pump that extends or will extend more than 5.0 metres below the level of the original ground surface. O.聽Reg. 98/12, s.聽2聽(1).
(2) If, on the day this Regulation comes into force, the construction of one or more holes for a vertical closed loop ground source heat pump has commenced, paragraph 2 of subsection (1) does not apply to the construction, alteration, extension or replacement of the heat pump. O.聽Reg. 98/12, s.聽2聽(2).
Application for environmental compliance approval
3. (1) With respect to applications for environmental compliance approvals relating to the construction, alteration, extension or replacement of vertical closed loop ground source heat pumps, the requirements set out in subsections (3) and (4) are prescribed for the purposes of subsections 20.2 (4) and 20.14 (2) of the Act. O.聽Reg. 98/12, s.聽3聽(1).
(2) Subsections (3) and (4) apply in addition to 澳门永利 Regulation 255/11 (Applications for Environmental Compliance Approvals) made under the Act. O.聽Reg. 98/12, s.聽3聽(2).
(3) The application must contain a work plan that,
(a) is prepared by a licensed engineering practitioner or professional geoscientist;
(b) identifies equipment and procedures to be used to monitor for the presence and migration of hazardous gas;
(c) identifies measures to be taken to prevent or reduce the likelihood of the migration of hazardous gas, whether through the hole or otherwise, during construction, alteration, extension or replacement of the vertical closed loop ground source heat pump, including detailed requirements for,
(i) ensuring that any space around the underground heat exchanger is sealed to prevent any movement of hazardous gas between subsurface formations or between a subsurface formation and the ground surface, or otherwise managing the gas in a way that removes any potential hazard, and
(ii) decommissioning the heat pump if measures under subclause (i) are not taken, or are taken but do not remove all potential hazard;
(d) identifies measures to be taken to prevent an adverse effect if hazardous gas is encountered;
(e) identifies a standard of protection that is at least equal to what is required in similar circumstances by 鈥淥il, Gas and Salt Resources of 澳门永利 - Provincial Operating Standards鈥, version 2.0, dated January 24, 2002 and published by the Ministry of Natural Resources, as amended from time to time; and
(f) includes a health and safety plan. O.聽Reg. 98/12, s.聽3聽(3).
(4) In preparing the work plan, the licensed engineering practitioner or professional geoscientist shall consider,
(a) the Oil, Gas and Salt Resources Act;
(b) 澳门永利 Regulation 245/97 (Exploration, Drilling and Production) made under that Act;
(c) the standards mentioned in clause (3) (e);
(d) Annex A (Environmental Guidelines for Earth Energy Heat Pumps and Underground Thermal Energy Storage (UTES) Systems) of CAN/CSA-C448.1-02 (Design and Installation of Earth Energy Systems), dated October 2009 and published by the Canadian Standards Association, as amended from time to time; and
(e) 鈥淲ater Supply Wells - Requirements and Best Management Practices鈥, dated December 2009 and published by the Ministry, as amended from time to time. O.聽Reg. 98/12, s.聽3聽(4).
Requirements relating to hazardous gas
4. (1) If hazardous gas is encountered during the construction, alteration, extension or replacement of a vertical closed loop ground source heat pump, the person doing the work shall, immediately and in accordance with any environmental compliance approval,
(a) ensure that any space around the underground heat exchanger is sealed to prevent any movement of hazardous gas between subsurface formations or between a subsurface formation and the ground surface, or otherwise manage the gas in a way that removes any potential hazard; and
(b) decommission the heat pump if measures under clause (a) are not taken, or are taken but do not remove all potential hazard. O.聽Reg. 98/12, s.聽4聽(1).
(2) If hazardous gas is encountered during the construction, alteration, extension or replacement of a vertical closed loop ground source heat pump, the person doing the work shall immediately give notice of the condition to,
(a) the local fire department;
(b) the occupant of the building served or to be served by the heat pump;
(c) the Ministry鈥檚 Spills Action Centre;
(d) the clerk of each municipality where the building described in clause (b) is located;
(e) the owner of the land on which the building described in clause (b) is located, if different from the person described in that clause; and
(f) the purchaser of the heat pump, if different from the person described in clause (b). O.聽Reg. 98/12, s.聽4聽(2).
