Storm Water - MS4 Municipal Program

  • U.S. Department of Transportation Announces $500 Million in TIGER Discretionary Grants
    The U.S. Department of Transportation recently announced that the Transportation Investment Generating Economic Recovery (TIGER Discretionary Grant program) has up to $500 million available for capital projects related to highways, bridges, public transportation, rail, ports, and intermodal projects. A primary selection criterion specifically mentions addressing environmental sustainability including avoiding adverse environmental impacts to water quality, providing environmental benefits such as ground water recharge in areas of water scarcity, and stormwater mitigation, including green infrastructure. Applicants are encouraged to provide quantitative information, including baseline information that demonstrates how the project will reduce stormwater runoff. Eligible applicants are State, local, and tribal governments, transit agencies, port authorities, metropolitan planning organizations, other political subdivisions of State or local governments, and multi-State or multi-jurisdictional groups applying through a lead applicant. TIGER applications are due no later than April 29, 2016 at 8 PM E.D.T. Additional details and webinars: https://www.transportation.gov/tiger

  • NOTICE: The U.S. Environmental Protection Agency's (U.S. EPA) Urban Waters Small Grants program is currently requesting proposals. For more information please see the U.S. EPA's Urban Waters web page (http://www2.epa.gov/urbanwaters/urban-waters-small-grants-mapping)

MS4 Municipal Program Content

Overview

The Municipal Storm Water Permitting Program regulates storm water discharges from municipal separate storm sewer systems (MS4s). MS4 permits were issued in two phases.

  • Under Phase I, which started in 1990, the Regional Water Quality Control Boards have adopted National Pollutant Discharge Elimination System (NPDES) storm water permits for medium (serving between 100,000 and 250,000 people) and large (serving 250,000 or more people) municipalities. Most of these permits are issued to a group of Co -permittees encompassing an entire metropolitan area.

  • On April 30, 2003, as part of Phase II, the State Water Resources Control Board issued a General Permit for the Discharge of Storm Water from Small MS4s (WQ Order No. 2003-0005-DWQ) to provide permit coverage for smaller municipalities (population less than 100,000), including non-traditional Small MS4s, which are facilities such as military bases, public campuses, prisons and hospital complexes. The Phase II Small MS4 General Permit covers Phase II Permittees statewide. On February 5, 2013, the Phase II Small MS4 General Permit was renewed and became effective on July 1, 2013.


Region-wide Permit

The Central Valley Water Board is developing a Region-wide MS4 Permit (Region-wide Permit) that could include both Phase I and II MS4 Permittees within the Central Valley region. Currently, each Phase I MS4 Permittee is covered under an individual permit issued by the Central Valley Water Board. Phase II MS4 Permittees are currently covered under the State Water Resources Control Board's Phase II MS4 (Order No. 2013-001 DWQ). Central Valley Water Board staff is developing a single Region-wide Permit that would promote greater watershed/drainage shed coordination and water quality measure protections, and promote greater program implementation efficiencies.

  • Some of the benefits of such an approach might include:
    1. A region-wide MS4 permit approach would conceptually use municipal resources more efficiently, leveraging resources at a regional level (monitoring and outreach);
    2. Increased flexibility;
    3. Relate constituents of concern to storm water program actions;
    4. Consistent standards across Central Valley region;
    5. May provide the ability for municipalities to prioritize storm water program elements; and
    6. Assess progress at regional, local, or watershed levels.

  • NOTICE OF PUBLIC HEARING
    A Tentative Region-wide General Permit for Discharges from Municipal Separate Storm Sewer Systems (MS4 General Permit) was circulated for public comment on 20 April 2016. The Tentative MS4 General Permit is available for download below:

  • Comments are due back to Central Valley Water Board staff no later than 5:00 pm on 20 May 2016. Comments received after this deadline may not be considered. Comments should be mailed to the Central Valley Water Board at 364 Knollcrest Drive, Suite 205, Redding, CA 96002, or emailed to dannas.berchtold@waterboards.ca.gov. If you have any questions regarding this matter please contact Dani Berchtold at (530) 224-4783 or via email at dannas.berchtold@waterboards.ca.gov.

    Central Valley Regional Water Quality Control Board proposes to adopt a new Region wide General National Pollutant Discharge Elimination System (NPDES) Permit and Waste Discharge Requirements to address discharges from Municipal Separate Storm Sewer Systems (MS4) within in its regional boundaries. Currently there are seven (7) individual Phase I MS4 permits covering 23 MS4 communities and 120 Phase II MS4 communities enrolled under the State wide MS4 Phase II permit (State Water Board Order WQ 2013-0001-DWQ). The tentative Region-wide General NPDES permit proposes to shift the focus of permit requirements from a level of actions to be implemented by the Permittee to identifying outcomes to be achieved by those actions. This permitting approach, referred to as a water quality focused framework, represents an important paradigm shift in the approach for MS4 permits within the Central Valley region. Any Phase I or II MS4 under the jurisdiction of the Central Valley Water Board may enroll in this Order

    The Proposed tentative Order will be considered at the 23/24 June 2016 Regional Board meeting. To be given full consideration, any comments or recommendations you may have must be submitted in writing to the Central Valley Regional Water Quality Control Board office no later than 5:00 pm on 20 May 2016. If you have any questions regarding this matter please contact Bryan Smith at (530) 224-4845, or at bryan.smith@waterboards.ca.gov or Dannas Berchtold at (530) 224-4783, or at dannas.berchtold@waterboards.ca.gov.
