1.1 Scope and Purpose

This recommended practice is a basic guide and information resource for activities to assist in providing increased assurance of a pipeline system's integrity. It covers design and construction considerations; system monitoring and controls; corrosion controls; inspections, reviews and audits; and damage prevention. The purpose of this recommended practice is twofold: to compile a wide base of current industry experience, knowledge, information, and management practices into a cohesive document comprising a range of best practices and to assist pipeline operators in increasing the integrity of their pipeline systems.

The facilities covered by this recommended practice include pipelines and pipeline segments, pumping stations, metering facilities, tankage facilities, and other facilities that may be integral to the operation of a hazardous liquid pipeline.

Information is presented in this recommended practice in the form of recommendations (designated by the use of the word "should") and in the form of mandates (designated by the use of the word "shall"). This recommended practice incorporates by reference a number of other standards, as well as the requirements set forth in 49 Code of Federal Regulations (CFR) 195 and other recommended practices. The distinctions in the referenced documents are not changed by the nature of their reference in this recommended practice.

It is the intent that this recommended practice supplement the minimum requirements of DOT 49 CFR 195 where applicable and be applied to those facilities outside the scope of these regulations as well.

Some monitoring, reporting, testing, and inspection intervals referenced in 49 CFR 195 as establishing requirements may not necessarily be justified on a risk assessment analysis.
