5. History of MAJOR CHANGES OF the Wastewater Treatment Design Criteria in Texas
The first consolidated design criteria was adopted by Texas State Department of Health on 9/18/1950.
This document was revised on 9/11/1961, 9/18/1968, 9/13/1970, 9/1/1974, 6/1/1981, 4/20/1990, 8/28/2008, 12/4/2015

6. General Procedure
a.       What’s the Summary transmittal letter procedure and what is needed in the letter
b.      How to request a variance
c.       What type of projects get called in and how often,
d.      What’s maintenance and why it doesn’t need to be submitted for review
e.      Regions will be looking for approval letters at inspection.

7. General Procedure f. Review procedure regarding TWDB, EAPP
g.       We approve on a project basis.  We’ll meet with suppliers/manufacturers to discuss new technology and approaches, but no carte blanche approval letters for technology
h.      We meet and provide feedback on pilot studies if requested

8. Rerating a WWTP Information necessary for rerating a wwtp
At least two of flow and influent data
Information on how the wwtp is operating
Design of the wwtp

9. Water Line vs. Wastewater Line
When a project is the installation of a water line that may cross a sewer line, then start with 290.  If it is a sewer line that may cross a water line, then start with 217.  But, coordinate with both rules to ensure that the most stringent directive is followed in cases where there are differences

10. Prohibition What are the prohibitions in the design criteria?
How many prohibitions are in the criteria?
How can I get a variance to a prohibition?
What is the prohibition do we see the most?
