41. Status of TPDES General Permit TXR040000

42. Proposed Changes Clarify SWMP approval process MS4 operator will not be required to implement SWMP until receiving written approval from the TCEQ TCEQ may require changes to the SWMP as part of the approval process TCEQ approval of the SWMP is a determination that SWMP meets the MEP standard Include additional non-storm water discharges TPDES Multi Sector General Permit (MSGP) for industrial activities TPDES Construction General Permit (CGP)

43. Proposed Changes (cont.) Add “force majeure” provision Permittee has the right to assert a force majeure (act of God, war, strike, riot, or other catastrophe) defense under 30 TAC § 70.7, when an event occurs that is otherwise a violation of a permit. Add provision allowing changes to BMPs Clarify SWMP responsibility for MS4 operators without authority to develop ordinances or implement enforcement actions i.e. counties, transportation authorities, and special districts Revise permit year and annual report due date

44. Noteworthy Items Endangered species Water quality protection Definition of “outfall” Reference to “surface water in the state” versus “waters of the U.S.” Outfall mapping requirement in illicit discharge detection and elimination MCM Designation criteria by which TCEQ could regulate additional MS4s

45. Noteworthy Items (cont.) Requiring third party compliance Non-traditional MS4s with varying enforcement e.g., counties, TxDOT, MUDs, irrigation districts, universities Clarification of “very discrete systems,” which would not be regulated under permit e.g. office buildings and ISDs TCEQ Review Period for SWMP Public Participation requirements public notice of NOI possible public meeting

46. Proposed Requirements Beyond Federal Regulations TCEQ determined certain additional requirements necessary to show compliance with the SWMP Includes the following proposed requirements: List groups considered for Public Education/Outreach, and document those not considered. List source(s) of information used to develop outfall map List construction site notices and NOIs Pollution Prevention/Good Housekeeping for Municipal Operations - maintain structural controls, dispose of waste associated with the maintenance of controls, and listing all municipal operations subject to permitting.
