Pipeline integrity management program

澳门金沙登录公司, we’re committed to protecting the public, 我们的员工, 公共和私有财产, and the environment as whole — all while providing reliable service to our customers. Pipeline integrity management plays an important role in preventing interruption to our customers’ energy service, maintaining our system integrity and preserving our investments for future generations.

As part of our integrity management strategy, we assess the integrity of our pipelines when they’re initially installed and we continue to review it throughout each pipeline’s service life. This occurs through periodic inspections and testing as well as historical data review.

The objective of our Integrity Management Program is to improve pipeline 安全 through a systematic approach involving data gathering, 风险评估, 完整的评估, 预防, 和缓解. The Pipeline and Hazardous Materials 安全 Administration (PHMSA) has developed specific High Consequence Area (杂环胺) and Moderate Consequence Area (MCA) regulations for the operations and maintenance of pipeline segments in populated areas. These regulations are more rigorous than pipeline segments outside of 杂环胺s and MCAs, and focus integrity management activities in areas w在这里 failure can cause the most harm.

澳门金沙登录公司, 安全 is our number one priority, and we generally apply more rigorous measures to the operation of all our pipeline facilities, not just what we’re required to do.

However, we can’t be everyw在这里 at once. Damage to pipeline facilities can occur in between inspections that we may not know about. Neighbors like you can assist us in maintaining a safe, secure, and reliable pipeline system. If you observe any unusual or suspicious activity near our pipeline facilities, 或者发生紧急情况, 请立即打电话给我们 888-890-5554.
 

我们还可以：

• Perform a risk analysis on a pipeline to see if t在这里’s anything else we should do to increase public 安全.
• Install automatic shut-off valves or remote-controlled valves to minimize the impact of leaks.
• Install computerized monitoring and leak-detection systems.
• Replace certain segments with pipe made of heavier wall thickness.
• Provide additional training to personnel about response procedures.
• Conduct drills with local emergency responders and implement additional inspection and maintenance programs.
   

High Consequence Area (杂环胺) means:
The radius within which the failure of a pipeline could have significant impact on people or property. A potential impact radius (PIR) is determined using a mathematical formula.

确定的地点是指：

1.  An outside area or open structure occupied by 20人以上 on at least 50 days in any 12-month period. The days don’t have to be consecutive.
2.  A building that is occupied by 20人以上 on at least five days a week for 10 weeks in any 12-month period. The days and weeks don’t have to be consecutive.
3.  A facility occupied by anyone who is confined, impaired mobility or would be difficult to evacuate.

When a High Consequence Area (杂环胺) is identified using a PIR, the length of the 杂环胺 extends along the pipeline from the outermost edge of the first potential impact circle that contains an identified site, or 20人或以上 buildings intended for human occupancy, to the outermost edge of the last potential impact circle that contains an identified site or 20人或以上 buildings intended for human occupancy.
 

The picture below provides a graphical example of this:
 

Moderate Consequence Area (MCA) means:

1. An onshore area that is within a potential impact circle, as defined in §192.903，包含：
   1. Five or more buildings intended for human occupancy; or
   2. 铺砌表面的任何部分, 包括肩膀, 指定的州际公路, 其他高速公路或高速公路, as well as any other principal arterial roadway with four or more lanes, 如 Federal Highway Administration’s Highway Functional Classification Concepts, 准则及程序, 第三节.1, and that does not meet the definition of an 杂环胺, as defined in §192.903.
2. The length of the MCA extends axially along the length of the pipeline from the outermost edge of the first potential impact circle containing either:
   1. Five or more buildings intended for human occupancy; or
   2. 铺砌表面的任何部分, 包括肩膀, 任何指定的州际公路, 高速公路或高速公路, as well as any other principal arterial roadway with four or more lanes, to the outermost edge of the last contiguous potential impact circle that contains either five or more buildings intended for human occupancy, or any portion of the paved surface, 包括肩膀, 任何指定的州际公路, 高速公路或高速公路, as well as any other principal arterial roadway with four or more lanes.
