  1. Review of Revised Regional Water Planning Requirements Spring-Summer 2013 | Matt Nelson Manager, Regional Water Planning

  2. Outline Background on planning requirements Purpose and nature of rule changes Summary of specific rule changes

  3. Background • BASIC PLANNING PARAMETERS: • water supply plan to meet DOR needs • 50-year planning horizon • 5-year planning cycle • categories of water use: • -municipal -manufacturing • -irrigation -mining • -livestock -steam-electric power

  4. Background • “The state water plan shall provide for the preparation for and response to drought conditions.” • - Guidance Principles for the State Water Plan Development §358.3(1)

  5. Background • “The state drought manager [TDEM] is responsible for managing and coordinating the drought response component of the state water plan.” • - Texas Water Code, Sec. 16.055. Drought Response Plan

  10. RWP Requirements Less Specific More Specific

  11. RWP Requirements Revised in 2012

  12. RWP Requirements Revised in 2012

  13. Planning Rules §355 §357 §358

  14. Types of Rule Revisions

  15. Purpose & Nature of Rule Changes • statutory changes • problems encountered during 2011 drought • outcomes from agency coordination

  16. Impact of Changes Rule changes will require RWPGs to: report additional (existing) information in plans collect, analyze, and consider additional information make additional recommendations

  17. Rule changes REGIONAL WATER PLAN CHAPTERS: drought response policy recommendations financing of WMSs plan adoption implementation & comparison description demands supply needs WMS evaluations plan impacts

  18. Rule changes Chapter with Revised Requirements: drought response NEW policy recommendations financing of WMSs plan adoption implementation & comparison NEW description demands supply needs WMS evaluations plan impacts

  19. Chapter 1: RWP Area Description Identify in the plan multiple historic droughts of record (DOR), if applicable - §357.30(9)

  20. RWP Area Description DOR = 1950s

  21. RWP Area Description DOR = 1950s

  22. RWP Area Description DOR = 1990s DOR = 1950s

  23. CHAPTER 3: Existing Water Supplies Where a DFC has been established…

  24. Development of DFCs

  25. Development of DFCs

  26. Development of DFCs

  27. Development of DFCs

  28. Development of DFCs Areas with MAGs

  29. Areas Without DFCs & ‘non-relevant’ areas (no MAGs)

  30. Areas Without DFCs ‘other’ local aquifer areas (no MAGs) & ‘non-relevant’ areas (no MAGs)

  31. Areas Without DFCs ‘other’ local aquifer areas (no MAGs) & ‘non-relevant’ areas (no MAGs) • RWPGs responsible for availability estimates

  32. CHAPTER 4: ID of Water Needs Secondary needs analysis to be performed after recommending conservation and reuse - §357.33 (e) New REPORTING REQUIREMENT based on data already developed by RWPG - no new data or work required

  33. Secondary Needs Analysis

  34. Secondary Needs Analysis

  35. Secondary Needs Analysis

  36. Secondary Needs Analysis calculated by TWDB & presented in plans

  37. Chapter 5 Potentially Feasible, Evaluated, Recommended WMSs

  38. Chapter 5: WMSs • TCEQ Environmental Flow Standards • potentially applicable BMPs • conservation sub-chapter • management supply factor (MSF) • other

  39. Environmental Flow Stds a.) All WMSs must adhere to relevant adopted environmental flow standards §357.34(d)(3)(B)

  40. Environmental Flow Stds

  41. Consider BMPs b.) Shall consider potentially applicable BMPs §357.34(f)(2)

  42. Conservation Sub-Chapter • c.) All Conservation recommendations will be gathered into a Sub-Chapter §357.34(g) • REORGANIZATION OF EXISTING PLAN CONTENT ONLY • - no new data or work required

  43. MSF • d.) Report calculated planning ‘MSFs’ - assuming all recommended WMSs are implemented. • §357.35(g)(2) NEW REPORTING REQUIREMENT based on data already developed by RWPG - no new data or work required

  44. MSF

  45. MSF

  46. MSF = ‘management supply factor’

  47. MSF • for each WUG • in each decade

  48. MSF • for each WUG • in each decade

  49. MSF provided by TWDB & presented in plans

  50. (example 1) MSF factor = 1.0
