Stormwater Management Program


Stormwater is defined as “stormwater runoff, snow melt runoff, and surface runoff and drainage” 40 CFR 122.26(b)(13). Stormwater is a resource and asset for California that should be managed in a sustainable manner as a source of water. Pollutants of concern in urban runoff include sediments, solids, nutrients, pathogens, oxygen-demanding substances, petroleum hydrocarbons, heavy metals, floatables, polycyclic aromatic hydrocarbons (PAHs), trash, pesticides and herbicides. In accordance with section 402(p) of the Federal Clean Water Pollution Control Act (Clean Water Act), NPDES permits are required for discharges from facilities from municipal storm water systems facilities and non-traditional facilities such as railroad tracks and stations. The Authority’s goal for stormwater management is to design, construct, and operate our facilities in compliance with requirements, to control pollutants, and to protect water quality resources in a sustainable manner.


The California High Speed Rail Authority Stormwater Management Program complies with the National Pollutant Discharge Elimination System (NPDES) Water Quality Order NO. 2013-0001-DWQ National Pollutant Discharge Elimination System (NPDES) General Permit No. CAS000004. The Authority qualifies as a non-traditional permittee under this order.

Public Education Program

I Pledge to Protect Every Drop

Protect Every Drop

The California High-Speed Rail Authority is proud to partner with the California Department of Transportation (Caltrans) on the Protect Every Drop campaign. We strive to educate Californians about stormwater pollution and to help the public learn how to reduce pollution throughout the state. Our water is precious — Protect Every Drop!

Construction Stormwater Program

High-speed rail construction projects follow the SWRCB Construction General Permit (Order 2009-00009-DWQ) and are required through High-Speed Rail Authority (Authority) contract to file all project registration documents, fees, and permit requirements through the SWRCB Storm Water Multiple Application and Report Tracking System (SMARTS). Each project phase includes approved Storm Water Pollution Prevention Plans written by the design builders and uploaded to SMARTS.

There are currently three active Authority projects in the SWRCB SMARTS system with active Waste Discharge Identification Numbers (WDID). Detailed information and compliance reporting can be found on the SMARTS website.

Construction Package 1 (CP 1), WDID# 5F20C369876: The CP 1 construction area is a 32-mile stretch between Avenue 19 in Madera County to East American Avenue in Fresno County.

Construction Package 2-3 (CP-2-3), WDID# 5F16C375735-469820: The CP 2-3 construction area extends approximately 60 miles from the terminus of Construction Package 1 at East American Avenue in Fresno to one mile north of the Tulare-Kern County line.

Construction Package 4 (CP 4), WDID#5F15C377556: The CP 4 construction area is a 22-mile stretch bounded by a point approximately one mile north of the Tulare/Kern County Line at the terminus of Construction Package 2-3 and Poplar Avenue to the south.

Construction Guidance Links

The following links may have guidance helpful to construction contractors to comply with SWRCB construction permit and portions of the municipal permit.

Design and Planning

The Authority developed a storm water management plan technical report in September 2014 to meet the requirements for the waste discharge requirements for the Phase II permit application. Within this stormwater management plan we detailed that the Authority will follow the Caltrans Stormwater Project Planning Design Guide (PPDG), Caltrans Highway Design Manual, and Authority environmental documents for each construction segment.

Maintenance and Operations

The Authority is currently designing and building its facilities. None are completed at this time. The operations and maintenance plans are currently being developed.

Facilities Operations Stations

The Authority is currently developing its facility designs and operations. These will include site design Best Management Practices to prevent storm water pollution.
