802.2.1 Adequacy for Normal Conditions. The requirements of this Code are adequate for safety under conditions usually encountered in the gas industry. Requirements for all unusual conditions cannot be specifically provided foi nes are all details of

engineering and construction prescribed; therefore, activities involving the design, construction. operation, or maintenance of gas transmission, gathering, or distribution pipelines should be undertaken using supervisory personnel having the experience or

knowledge to make adequate provision for such unusual conditions and specific engineering and construction details. All work

performed within the scope of this Code shall meet or exceed the safety standards expressed or implied herein.

802.2.2 More Complete Analysis. The Code genc’rally specifies a simplified approach for many of its requirements.

(a) For design and construction, a designer may choose to use a more ngorous analysis to develop design and construction

requirements. When the designer decides to take this approach, the designer shall provide to the operating company details and

calculations demonstratirig that design, construction, examination, and testing are consistent with the criteria of this Code.

These details shall be adequate for the operating company to verify the validity of the approach and shall be approved by the

operating company. The detaiLs shall he documented in the engineering design.

(b) For operation and maintenance, an operating company may choose to use a more rigorous analysis to develop operation and

maintenance requirements. When the operating company decides to take this approach, the operating company shall provide details and calculations demonstrating that such alternative practices are consistent with the o&iectlses of this Code. The details shall be documented in the operating records and retained for the lifetime of the facility

802.2.3 Safety. This Code is concerned with

(a) safety of the general public.

(b) employee safet to the extent that it is affected by basic design, quality of materials and workmanship, and requirements for testing, operations, and maintenance of gas transmission and distribution facilities. Existing industrial safety procedures

pertaining to work areas, safety devices, and safe worl practices are not intended to be supplanted by this Code.
