Applicants for EPA carbon-storage permits must persuade the agency that they can contain both the plume of injected carbon dioxide and a secondary plume of saltwater that the CO2 displacements from the rock—what drilling engineers call the pressure pulse. The EPA requires evidence that neither plume will contaminate drinking water while a project is operating and for a default period of 50 years after CO2 injection stops—but the agency can decide to shorten or lengthen that for a particular project.
Stream employs a well-heeled team, including oil industry veterans and a former top EPA official, to shepherd the permit application, which was submitted in October 2020 and which remains, nearly two years later, under agency review.

Heading up the technical work is a British petroleum geologist named Peter
