Orange County TMDL

 Local Stakeholder Advisory Group formed in 2002 State & Local Government Agencies, Municipalities, Water Districts and the Public  15 Planning Meetings 2002-2006  Adopted by TCEQ – June, 2007  Approved by EPA – August, 2007

SLIDE 10

Orange County TMDL Implementation Plan (I-Plan)

 18 Meetings to Develop I-Plan 2006-2014  I-Plan public comment period closed – March, 2015  TCEQ consideration for formal approval – August 5, 2015

SLIDE 11

Solution – Regional WWTF

Best long-term solution recommended in the TMDL I-Plan is regionalization of wastewater treatment in the project area (Regional WWTF) Benefits include:

 Remove point source discharges from Adams/Cow Bayous  Reduce non-point source loading in Adams/Cow Bayous  Provide clean water to the Gulf of Mexico ecosystem

SLIDE 12

Challenges – Regional WWTF

Significant Challenges include:

 Large Geographical Area  Funding Limitations for a Total Project Cost – $50,000,000

Because of the significant benefits expected from regionalization, Orange County TMDL stakeholders are actively pursuing plans and funding to regionalize wastewater treatment and collection

SLIDE 13

Summary

We believe the water quality improvements realized from a regionalization project make it

ne of the best funding candidates

available for the restoration needed along the Gulf Coast after the Deepwater Horizon spill
