CO2 Pipelines - from WRI




















Although CO2 pipelines are classified as hazardous, CO2 is not defined as a
hazardous substance. It is a Class L, highly volatile, nonflammable/nontoxic
material (CFRg, CFRe, Appendix B, Table 4).

CO2 pipelines are treated as hazardous and are reviewed as high-risk hazardous pipelines when they have a diameter greater than 457mm(18 in) or when they pass through High-Consequence Areas.

States certified to regulate intrastate pipelines are: Alabama, Arizona, California, Louisiana, Maryland, Minnesota, Mississippi, New York, Oklahoma, New Mexico, Texas, Virginia,Washington, and West Virginia.

49 CFR § 195.2 defines low-stress pipeline as a hazardous liquid pipeline that is
operated in its entirety at a stress level of 20 percent or less of the specified minimum-yield strength of the pipeline (CFRf).

49 CFR § 195.2 defines rural area as an area outside the limits of any incorporated or unincorporated city, town, village, or any other designated residential or commercial area, such as a subdivision, a business or shopping center, or community development. The rural areas are considered to be the nonenvironmentally sensitive areas (CFRf).

An easement is a limited perpetual interest in land that allows the pipeline owner
to construct, operate, and maintain a pipeline across the land. An easement does
not grant an unlimited entitlement to use the right of way. The rights of the
easement owner are set out in the easement agreement.

Eminent domain is the power of government to take private land for public use.
Under current law there is no federal eminent domain power granted for the
construction of CO2 pipelines. A number of states, however, do allow the use of
eminent domain for CO2 pipeline construction under certain conditions.
