1.1 This Standard specifies criteria to develop emission reduction practices and programs. 1.2 This Standard addresses fugitive and vented emissions from point sources in the following sectors (see Figure 1) of the upstream oil and gas industry from wells, pipelines, and facilities associated with a) crude oil production and shale oil; b) oil sands – in situ bitumen production, including thermal (i.e., steam-assisted gravity drainage and cyclic steam stimulation) and non-thermal (i.e., water and polymer injection schemes) projects; c) natural gas production, including conventional, coal bed methane, and shale gas; and d) natural gas processing. Application of this Standard to new and existing wells, pipelines, and facilities is specified within each clause of the Standard. 1.3 This Standard does not include requirements for fugitive and vented emissions from vent sources or area sources for the following sectors: a) crude oil terminals, including pipeline and rail terminals b) downstream sector (including refineries and upgraders); c) transmission and distribution applications; d) oil sands – mining operations; e) oil sands – upgraders; f) straddle plants; g) underground hydrocarbon storage; h) liquefied natural gas plants; and i) offshore applications. 1.4 Reporting requirements are the responsibility of the regulator having jurisdiction. 1.5 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
