TMDL Issues Review TMDL Issues Review Presentation Transcript

  • Los Angeles River Bacteria TMDL City Concerns Ronald Bates City of South Gate CCCA City Manager’s Meeting June 24, 2010 1
  • LA River Bacteria TMDL  25-year mandate impacting 40 watershed cities, LA County and Caltrans  Establishes both wet and dry-weather “numeric limits” for bacteria in the LA River  Water quality standard based on REC-1 (swimming requirement) in the River  Swimming standard established in 1975, with no consideration of costs or practicality of the use 2
  • Big picture: Los Angeles River Bacteria TMDL  TMDL implementation for just dry weather will be very expensive and will likely compromise other city services. ($1.1 billion estimate for drain diversions)  $5.4 billion estimate by the Regional Board for both wet and dry-weather compliance  It will be difficult, if not impossible, to meet current bacteria standards because of in channel sources  No known methods for compliance with wet weather TMDL 3
  • Is the REC-1 Use Appropriate?  Dry weather flows in some reaches are very shallow  Channels are extensively modified for flood control purposes, and access is restricted or prohibited in many reaches  There is far less contact recreation in river than at the beaches – we may want the ability to direct resources to Breakwater Reconnaissance Study or other beach protection measures (BMP)  In wet weather, recreation is dangerous 4
  • Concerns with objectives  Bacteria are prolific and re-grow in the environment  Non-human sources are significant (Storm drain and tributary inputs are only a fraction of the bacteria loading, so controlling city storm drains won’t attain water quality standards  During dry weather, rivers are less important as a source of bacteria at beaches 5
  • Some sources are natural and/or difficult to control  Wildlife activity and waste (migratory and shore birds) Birds in Rio Hondo  Bacteria re-growth in sediment Birds in Los Angeles River  Resuspension from disturbed sediment  Homeless encampments 6
  • Only 10-50% of bacteria enter from storm drains and tributaries  Dry weather monitoring, 6 events, LA River Reach 2  Controlling inputs will likely not result in attaining standards in the river  Unclear how compliance can be achieved 7
  • Dry Weather Costs LAR Bacteria >$1,000,000,000 Santa Monica Beaches = $46,000,000 8
  • Wet Weather Costs LAR Bacteria = $5,400,000,000 Santa Monica Beaches = $400,000,000 9 Source: www.you-are-here.com/location/la_river.html
  • Economic and Budget Impacts  Study by the GCCOG showed high unemployment in the watershed will continue for several years – hampering city revenues  In a survey of the watershed cities – 90% have budget deficits, 86% of reduced city services, 50% of implemented hiring freezes and 25% have laid off employees  The survey revealed that the TMDL will add 8% annually to the average city budget  New fees will be difficult to get voter approval 10
  • Regional funding approach for bacteria TMDL Estimated costs for dry weather only Annual costs Aggregate City Years 4-12 Years 13-23 Years 24-32 costs Alhambra $250,566 $663,264 $884,352 $17,510,166 Commerce $227,626 $602,540 $803,387 $15,907,057 Los Angeles $6,207,963 $16,652,386 $22,203,152 $438,876,281 LA County $1,861,010 $4,926,208 $6,568,276 $130,051,862 Monrovia $311,005 $823,249 $1,097,655 $21,733,679 South Gate $247,919 $656,257 $875,010 $17,325,188 Cost estimates are based on funding formula developed for metals TMDL 11

  • Unemployment for select cities  City Aug. 2008 Jan. 2010 %Increase  Commerce 14.8% 24.2% +9.4%  Compton 14.1% 22.0% +7.9%  Bell Gardens 13.2% 20.6% +7.4%  Lynwood 13.1% 20.5% +7.4%  Huntington Park 12.3% 19.4% +7.1%  Paramount 12.1% 19.0% +6.9%  Maywood 12.0% 18.9% +6.9%  South Gate 10.5% 16.7% +6.1%  Montebello 9.1% 14.7% +5.6%  Long Beach 9.0% 14.5% +5.5%  LA County 8.2% 13.2% +5.5%  State 7.7% 13.2% +6.5%  U.S. 6.1% 9.7% +3.6%  Source: Economic Development Department 13
  • What’s the Alternative?  Cities in Lower Los Angeles River have submitted the Water Conservation Plan for dry-weather compliance  This plan would cover major portions of the River south of the City of Los Angeles (Reaches 1 & 2 and their tributaries)  BMP based plan – not “numeric limits”  A wet-weather task force would be formed to further study wet weather issues 14
  • What Can the Watershed Cities Do?  Get up to speed! Review the 24 comment letters from cities, LA County and Caltrans  Prepare a written statement to submit to the Regional Board’s public hearing on July 9, 2010  Concentrate on the hardships your community is facing and the impacts of the TMDL  Send an elected official to testify! 15
  • July 9th Regional Board Hearing Meeting Location City of Glendale, City Council Chambers – 613 E. Broadway Blvd. Time 9:00 a.m. 16
