Any authority that is not delegable by statute, or specified as non-delegable in a subpart directly, is not delegated - this would include any specific requirements that are specified as not delegable in the General Provisions (Subpart A) and individual Subparts.  The original authority on which the Part 61 NESHAP delegations were based [CAA section 112(d)(1)] was removed in the 1990 CAA Amendments and replaced by CAA section 112(l).  Since Part 63 Subpart E now implements CAA section 112(l),  any revisions to existing Part 61 delegations would follow Part 63 Subpart E; authorities which may not be delegated include the following Part 63 General Provisions (Subpart A):

     §63.6(g) Approval of Alternative Non-Opacity Emission Standards
     §63.6(h)(9) Approval of Alternative Opacity Standards
     §63.7(3)(2)(ii) and (f)  Approval of Major Alternatives to Test Methods
     §63.8(f)  Approval of Major Alternatives to Monitoring
     §63.10(f)  Approval of Major Alternatives to Recordkeeping and Reporting

The Texas Commission on Environmental Quality (TCEQ) has received full automatic delegation for all existing and future Part 61 NESHAP, effective 12/28/1982 (48 FR 20693), with the exception of the following Subparts pertaining to emission standards for certain Radionuclides:  B, H, I, K, Q, R, T, and W.
