1 acre cultivation equivalent means a suite <strong>of</strong> operations including inoculation, cultivation,<br />
harvest, and processing sized with the capability to process and produce gallons <strong>of</strong> algal bi<strong>of</strong>uel<br />
intermediate per day. The modeled BTO baseline system described in the MYPP is conceived<br />
around an open raceway pond. As an example, 1 acre <strong>of</strong> cultivation in the modeled baseline would<br />
require subsequent unit operations at the following ideal scales:<br />

This information is presented to describe the intent <strong>of</strong> BTO in establishing a 1 acre cultivation<br />
equivalent requirement for the FOA. To meet the intent <strong>of</strong> the FOA, applicants are expected to<br />
present their proposed system, which is clearly unlikely to exactly match the model baseline, in<br />
comparable terms.<br />
“Algae”, “Algal” refer to microalgae, macroalgae, and cyanobacteria. Aquatic plants such as<br />
duckweed and eelgrass are not algae.<br />
“Amendment” means a revision to a Funding Opportunity Announcement<br />
"Applicant" means the legal entity or individual signing the Application. This entity or individual<br />
may be one organization or a single entity representing a group <strong>of</strong> organizations (such as a<br />
Consortium) that has chosen to submit a single Application in response to a Funding Opportunity<br />
Announcement.<br />
"Application" means the documentation submitted in response to a Funding Opportunity<br />
Announcement.<br />
