The flowchart and requirement reference table (RRT) footers include an amended date. The amended date is the date of the rule text amendment that is incorporated into the flowchart and RRT; it may not be the date the rule was last amended. The following numbers indicate only if rule text and/or historic rule opinions are available for the respective subpart, and explain why flowcharts and RRT are not included.
- " 1 " RRT and flowcharts will not be developed for general provisions or emission guidelines.
- " 2 " RRT and flowcharts will not be developed for these rules because there are less than 5 sites in Texas.
- " 3 " RRT and flowcharts will not be developed for these rules because they are sitewide requirements.
- " 4 " RRT and flowcharts for these rules are currently in development and will be provided as they are finalized.
- " 5 " RRT and flowcharts will not be developed for these rules because these subparts are referenced subparts of 40 CFR parts 60, 61, or 63.
