The timeline’s Slower / Typical / Faster control does not pull live agency clocks. Each of nine reviews in the rule set carries three duration estimates, in days, and a tag for where that number came from. Faster uses the low column, Typical the middle, Slower the high. The large day count on the timeline is the longest path to an Application for Permit to Drill, not the sum of every row. Reviews that can run in parallel do.
Statutory clock. Only ESA Section 7 formal consultation is tagged this way: 90 / 135 / 180 days. The typical 135 is 50 CFR 402.14 — 90 days to conclude consultation, 45 days to issue the biological opinion. The slow band (180) is the rule set’s allowance for a longer case, not a second statutory number.
Published agency figure. NEPA environmental assessment (270 / 365 / 540) and ESA informal consultation (45 / 60 / 90). These are numbers agencies publish, not scraped from a docket for Dixie Valley.
Stated assumption. Section 106, UIC Class V, biological assessment and survey seasons, Nevada water right, NEPA decision, and APD. Citations on those rows name the statute or regulation that creates the review. They do not, by themselves, supply the days.

The same rows, with triggers and prerequisites, are on the timeline under Rule set. The 570–1170 range under the typical total is this table’s low and high columns run on the current conditions, not a confidence interval from a model.
