On April 7, 2015, the State Water Resources Control Board (SWRCB) adopted state-wide Trash Provisions to two (2) of their Water Quality Control Plans:
- Ocean Waters of California Plan
- Inland Surface Waters Plan
These provisions are referred to as Trash Amendments and are directed to Phase I and Phase II MS4 permittees who retain regulatory authority over Priority Land Uses.
|December 2, 2015
||The Trash Amendments became effective with the approval of the Office of Administrative Law (OAL).
|January 12, 2016
||The US EPA approved the Trash Amendments.
- The Trash Amendments apply to all surface waters of the State.
- The Trash Amendments prohibit the discharge of trash to surface waters of the State as well as the deposition of trash where it may be discharged into surface waters of the State.
PRIORITY LAND USES
Priority Land Uses are developed sites that include:
- High Density Residential (10 or more Dwelling Units/Acre)
- Mixed Urban
- Public Transportation Stations and Stops
- Alternative Areas determined by the Permittees
- Other Areas Determined by the State
Permittees must select ONE of the following compliance tracks:
Track 1 Shall:
Install, operate, and maintain state-certified full-capture devices that capture stormwater runoff from Priority Land Uses.
Demonstrate, on average, a 10% annual installation rate for ten consecutive years starting from the effective date of the first implementing MS4 permit.
Track 2 shall:
Install, operate, and maintain a combination of full-capture devices, multi-benefit projects, LID BMPs, or Institutional (source) controls.
Demonstrate Full-Capture Equivalency through an Implementation Plan and annual Monitoring and Reporting.
Provide baseline and annual assessments showing 10% annual load reductions for ten consecutive years starting from the effective date of the first implementing MS4 permit.
Permittees must select a compliance track and submit any preliminary deliverables according to their respective Order by the following dates:
- Santa Ana Region – Aug 31, 2017
- Santa Margarita Region – Sep 5, 2017
- Whitewater Region – Sep 1, 2017
Subsequently within 15 months, Track 1 Permittees must submit their final deliverables according to the deadlines listed below for Track 2.
Permittees selecting Track 2 must submit their respective deliverables by the following dates:
- Santa Ana Region - Nov 30, 2018
- Santa Margarita Region – Dec 3, 2018
- Whitewater Region – Dec 1, 2018
The deadline for full compliance varies between regions but must be achieved within ten years from the effective date of each region’s first implementing MS4 permit.
Is there existing trash capture plans, approved devices, and efforts already underway?
Yes, the Bay area and Los Angeles have been addressing similar requirements for approximately the last 10 years. Any new devices will have to be approved by the State Water Board.
Is there a single location where I could find many of the existing documents?
The District will be posting existing plans and documents on their website.
Are we going to address this issue as part of our regional MS4 programs?
As of now, each MS4 Permittee is responsible to comply with the trash amendments for the priority land uses within their jurisdiction. The District is willing to assist however possible and is open to ideas.
Will a land use map be provided?
Yes, the District has provided preliminary mapping based on existing land uses. However, it is up to each MS4 Permittee to determine priority land uses for compliance.
