Current through Register 2024 Notice Reg. No. 38, September 20, 2024
Regional Board Resolution 98-69, adopted on April 17, 1998, and Regional Board Resolution No. 98-101, adopted on October 9, 1998, by the Santa Ana Regional Water Quality Control Board (SARWQCB), modified the regulatory provisions of the Water Quality Control Plan for the Santa Ana Region by establishing a Total Maximum Daily Load (TMDL) for sediment discharged in the Newport Bay (Bay)/San Diego Creek watershed (Watershed). Phase 1 of the TMDL provides:
(1) quantifiable targets for sediment deposition in Upper Newport Bay and the annual sediment load entering the Watershed;
(2) load allocations for sediment discharged from specific land uses in the Watershed;
(3) allowances for waivers of waste discharge requirements for maintenance dredging of flood control channels and for drainage channelization and stabilization projects under specified conditions;
(4) requirements for sediment control measures to reduce dredging frequency of in-Bay sediment basins; and
(5) maintenance requirements for in-channel and foothill sediment basins. Phase 2 of the TMDL provides specific monitoring requirements and methods for reassessment of the TMDL and specifies that required monitoring plans be approved by the SARWQCB at a duly noticed public hearing as per Chapter 1.5, Division 3, Title 23 of the California Code of Regulations (Section 647 et seq.).
1. New section filed 2-2-99; amendments approved by OAL and effective per Government Code section 11353 on 2-2-99 (Register 99, No. 6).
