§ 1.7 Equipment and Facilities

A.Standard Practice#

1.The gas facilities of the LDC shall be constructed, installed, maintained and operated in accordance with accepted good engineering practice in the gas industry to assure, as far as reasonably possible, continuity of service, uniformity, in the quality of service furnished and the safety of persons and property.#

2.In determining standard practice, the Division has incorporated by reference in §§ 1.1(A) and (B) of this Part, and the LDC shall use, the applicable provisions of the most recent editions of 49 C.F.R. Parts 190-199 and Part 40 Pipeline Safety Regulations, NFPA 54 National Fuel & Gas Code, NFPA 58 Storage and Handling of Liquefied Petroleum Gases, NFPA 59 Storage and Handling of Liquefied Petroleum Gases at Utility Gas Plants, and NFPA 59A Production Storage and Handling of Liquefied Natural Gas (LNG), except as any of the foregoing may in any particular case be modified by statute, ordinance, orders, rules or regulations by governmental bodies or agencies having jurisdiction. The LDC shall be guided by the following American National Standards Institute (ANSI) publications:#

a.ANSI/API 2530, "Orifice Metering of Natural Gas and Other Related Hydrocarbon, A.G.A. Report No. 3," incorporated by reference in § 1.1(E) of this Part, as follows:#

(1)Part I, "General Equations and Uncertainty Guidelines," (1990) (A.G.A. Catalog No. XQ9017).#

(2)Part II, "Specification and Installation Requirements," (1991) (A.G.A. Catalog No. XQ9104).#

(3)Part III, "Natural Gas Applications," (1992) (A.G.A. Catalog No. XQ9210).#

(4)Part IV, "Background Development, Implementation Procedures, and Sub-Routine Documentation for Empirical 33 Flange-Tapped Discharged Coefficient Equation," (1992) (A.G.A. Catalog No. XQ9211).#

b.ANSI B109.1, "Diaphragm Type - Gas Displacement Meters, Under 500 Cubic Feet per Hour Capacity," (1992) (A.G.A. Catalog No. X69218), incorporated by reference in § 1.1(F) of this Part.#

c.ANSI B109.2, "Diaphragm Type - Gas Displacement Meters, 500 Cubic Feet per Hour Capacity and Over," (1992) (A.G.A. Catalog No. X69219), incorporated by reference in § 1.1(F) of this Part.#

d.ANSI B109.3, "Gas Displacement Meters, Rotary Type," (1992) (A.G.A.Catalog No. X69220), incorporated by reference in § 1.1(F) of this Part.#

e.ANSI Z223.1 National Fuel Gas Code. The Division adopts by reference as rules, and the LDC shall use, the following American Society for Testing and Materials (ASTM) publications, incorporated by reference in § 1.1(G) of this Part:#

(1)ASTM specification D-1826 "Calorific Value of Gases in Natural Gas Range by Continuous Recording Calorimeter," (D1826-88).#

(2)ASTM specification D-1945 "Method for Analysis of Natural Gas by Gas Chromatography," (D1945-91).#

(3)ASTM specification D-3588 "Method for Calculating Calorific Value and Specific Gravity (Relative Density of Gaseous Fuels)," (D3588-91)#

B.Construction and Maintenance#

Each LDC shall construct, install, operate and maintain its plant, structures, equipment, and gas pipelines in accordance with standard practice, as defined in the paragraphs above, and in such manner as to best accommodate the public and to prevent interference with service provided by other public utilities.#
