Is there documentation that supports the Hach Method 8367, Coliforms-E. coli as an EPA equivalent procedure?
Summary
Method 8367 compliance documentation
Answer

Attached is Federal Register Vol 72, No 57, which was published on Monday, March 26, 2007.  This publication highlights the changes made to 40 CFR Part 136.  The register notes that Table IA has been updated and renamed IH.  Table IH is shown on page 9 of the pdf file, or page 14227 of the register.
 
For E. coli, the register calls out EPA Method 1103.1 for a 2-step membrane filtration procedure.  This is the method that calls out m-TEC agar.
 
For E. coli, the register calls out EPA Methods 1603 and 1604, which use modified m-TEC agar and MI media, respectively, for "Single step" methods.  It also notes the use of m-ColiBlue24 as an "Other" method.
 
For the detection of E. coli, two things are recommended:

1)  Check with local regulators to ensure that *any* alternate method they switch to will be acceptable
2)  Use modified m-TEC as an alternate media, provided that (1) is done above
 
This is consistent with the EPA, standard methods, and with 40 CFR Part 136.
