A. Implementation

1. The State Water Board shall reopen and amend this General Permit,
including Attachment E, the Fact Sheet and other applicable Permit
provisions as necessary, in order to incorporate TMDL-specific permit
requirements, as described in Findings 38 through 42. Once this General
Permit is amended, Dischargers shall comply with the incorporated TMDL-
specific permit requirements in accordance with any specified compliance
schedule(s). TMDL-specific compliance dates that exceed the term of this
General Permit may be included for reference, and are enforceable in the
event that this General Permit is administratively extended or reissued.

2. The State Water Board may, at its discretion, reopen this General Permit to
add TMDL-specific permit requirements to Attachment E, or to incorporate
new TMDLs adopted during the term of this General Permit that include
requirements applicable to Dischargers covered by this General Permit.
