Hello Mary,
Thank you for sending the information and working with Caltrans on this project to install a trash capture device in the City of Richmond. This email gives the Water Board’s acceptance of the CIA trash capture project proposal that you describe in your email below. Our approval of this cooperative project with Caltrans is conditioned on submittal of the following information by the City and/or Caltrans once project planning and design is finalized, and prior to construction:
Map(s) delineating the area draining to the trash capture devices. Maps should identify the areas and trash generation rating of Caltrans and City ROW to be controlled for trash by the device. GIS mapping and/or as-built plans showing the storm drain system draining to the trash capture device. Storm drain information should correspond with the drainage area maps. Breakdown of Caltrans and City ROW acres controlled by the devices and the trash generation rating of those areas.
Final design plans and calculations.
Confirmation that the device meets the requirements of MRP Provision C.10 and is on the State Board list of approved trash capture devices.
Final project agreements between Caltrans and the City. These should include identification of the party responsible for ongoing operation and maintenance of the device once installed. If operation/maintenance responsibilities are not described in the final agreements, provide this information in a separate document.
Thank you for identifying this opportunity to reduce trash discharges through the MS4 and working cooperatively with Caltrans to implement the project. This email serves as our conceptual approval of the project. Please let Derek Beauduy or me know if you have questions or if there are significant changes to the project as the planning and design process moves forward.
Thanks,

EXTERNAL:
To Whom it May Concern:
As you may be aware, the City of Richmond and Caltrans are seeking a partnership to design and construct a large trash capture device in Richmond.
The proposed device is a debris/nutrient separating baffle box (DSBB/NSBB) that will treat 840 acres of land: 38 acres are Caltrans right-of-way, 84 acres are from the City of Richmond, and 723 acres are from the City of El Cerrito.
The attached map shows the drainage area.
This location was previously approved. However, due to physical constraints (utilities, ground impediments), the location was changed.
Now, with the additional funding, the device can be installed.
Project Scope:
These CDS units will screen, separate and trap debris, sediment, and oil and grease from stormwater runoff. The units have been rated as being effective at trapping 80% of sediment at either the 140 or 175 micron level depending on unit type. Thus, they will achieve load reductions of PCBs and Hg, beside trash.
The proposed projects gear toward compliance of TMDLs of trash, PCBs and Mercury, as set forth by in the San Francisco Bay Regional Water Resource Control Board. Ultimately, this project posts a watershed-based solution to reduce pollutant loadings, trash, and PCBs and Mercury in sediments, from entering local watersheds and the San Francisco Bay from three different jurisdictions, City of Richmond, City of El Cerrito, and Caltrans, thus enhancing water quality for beneficial and recreational uses.
Once we enter into an agreement with Caltrans, our projected spending is as follows:

3 The City of Richmond and Caltrans is seeking Water Board approval before moving ahead with funding this project.
Please let us know of the Board’s support and if any additional documentation is needed to assess this project, or if you have any further questions.
