Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On October 1, 2009, the Los Angeles Regional Water Quality
					 Control Board adopted Resolution No. R09-005, amending the Water Quality
					 Control Plan for the Los Angeles Region by establishing a Total Maximum Daily
					 Load (TMDL) for OC Pesticides, PCBs, Sediment Toxicity, PAHs, and Metals for
					 Colorado Lagoon. The TMDL includes numeric targets for the water column based
					 on California Toxics Rule criteria for protection of human health, sediment
					 targets based on Effects Range-Low sediment quality guidelines compiled by the
					 National Oceanic and Atmospheric Administration, and fish tissue targets based
					 on Office of Environmental Health Hazard Assessment (OEHHA) Fish Contaminant
					 Goals. Mass-based waste load allocations for Municipal Separate Storm Sewer
					 System (MS4) permittees, including the City of Long Beach, the Los Angeles
					 County Flood Control District, and Caltrans are allocated to five major storm
					 drain outfalls that currently discharge to the lagoon. Concentration-based
					 waste load allocations are assigned to the above-mentioned MS4 permittees for
					 other minor stormwater outfalls, minor National Pollutant Discharge Elimination
					 System (NPDES) permittees, and other stormwater and non-stormwater
					 permittees.
The TMDL requires implementation to be carried out by
					 responsible jurisdictions including, but not limited to, the City of Long
					 Beach, the Los Angeles County Flood Control District and Caltrans. The proposed
					 implementation actions include a range of activities that are proposed by the
					 Los Angeles County Flood Control District and City of Long Beach in the Los
					 Angeles County Termino Avenue Drain Project and Colorado Lagoon Restoration
					 Project, respectively. Implementation of the proposed actions should result in
					 attainment of the TMDL allocations. If the proposed actions are not implemented
					 or otherwise do not result in attainment of allocations, additional remedial
					 actions will be necessary.
The TMDL requires the permitted MS4 permittees, minor NPDES
					 permittees, and other stormwater and non-stormwater dischargers to achieve
					 applicable wasteload allocations within 7 years. The TMDL requires responsible
					 parties for the assigned wasteload allocations to submit monitoring and
					 reporting plans within six months of the effective date of the TMDL.
					 Responsible agencies are required to submit progress reports to provide updates
					 on the status of implementation actions performed under the TMDL every two
					 years after the effective date of the TMDL. The plan is required to contain
					 mechanisms to ensure progress toward meeting the assigned wasteload
					 allocations.
