Hazard Mitigation Planning: Practices for Land Use Planning and Development Near Pipelines [open pdf - 4MB]
From the foreword: "Hazardous liquid and gas transmission pipelines run through nearly 2,800 of the 3,141 counties in the United States. Pipelines transport hazardous materials that, when released, can pose a significant threat to people as well as the built and natural environment near the pipeline. Pipeline failures are characterized as low-probability, high-consequence events. They do not happen often; however, the residents of any community that have experienced a significant pipeline failure are likely, in retrospect, to wish they had become more aware of the pipeline and informed of the potential risk. [...] One way communities can understand and influence the risks of pipeline failures is through appropriate land use and development policies and practices. Land development in close proximity to hazardous liquid and gas transmission pipelines increases the likelihood of damage to the pipelines and the potential for impact to the community from a pipeline failure. Additionally, without appropriate planning, land development can impede access needed for the safe operation and maintenance of the pipeline and for emergency response in the event of a pipeline accident."
