Water supply reliability assessment n/a Page 7-15 52 x 7.3 Section 7.3 10635(b)(1) Include a description of the data, methodology, and basis for one or more supply shortage conditions that are necessary to conduct a drought risk assessment for a drought period that lasts five consecutive years. Water supply reliability assessment n/a Page 7-15 53 x 7.3 Section 7.3 10635(b)(2) Include a determination of the reliability of each source of supply under a variety of water shortage conditions. Water supply reliability assessment n/a Pages 7-15 to 7-16 54 x 7.3 Section 7.3 10635(b)(3) Include a comparison of the total water supply sources available to the Supplier with the total projected water use for the drought period. Water supply reliability assessment 7-5 Page 7-17 55 x 7.3 Section 7.3 10635(b)(4) Include considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria. Water supply reliability assessment n/a Pages 3-4, 4-11, 6-33 and 7-15 56 x 8 Chapter 8 10632(a) Provide a water shortage contingency plan (WSCP) with specified elements below. Water shortage contingency planning n/a Appendix D 57 x 8 Chapter 8 10632(a)(1) Provide an analysis of water supply reliability (from Guidebook Chapter 7) in the WSCP. Water shortage contingency planning n/a Appendix D 58 x 8.2 Section 8.2 10632(a)(2)(A) Provide the written decision-making process and other methods that the Supplier will use each year to determine its water reliability. Water shortage contingency planning n/a Appendix D 59 x 8.2 Section 8.2 10632(a)(2)(B) Provide data and methodology to evaluate the Supplier’s water reliability for the current year and one dry year pursuant to factors in the code. Water shortage contingency planning n/a Appendix D 60 x 8.3 Section 8.3 10632(a)(3)(A) Define six standard water shortage levels of 10%, 20%, 30%, 40%, 50% shortage, and greater than 50% shortage. These levels shall be based on supply conditions, including percent reductions in supply, changes in groundwater levels, changes in surface elevation, or other conditions. The shortage levels shall also apply to a catastrophic interruption of supply. Water shortage contingency planning n/a Appendix D 61 x 8.3 Section 8.3 10632(a)(3)(B) Suppliers with an existing WSCP that uses different water shortage levels must cross reference their categories with the six standard categories. Water shortage contingency planning 8-1 Appendix D and Page 8-1 62 x 8.4 Section 8.4 10632(a)(4)(A) Suppliers with WSCPs that align with the defined shortage levels must specify locally appropriate supply augmentation actions. Water shortage contingency planning 8-2 Appendix D and Pages 8-2 63 x 8.4 Section 8.4 10632(a)(4)(B) Specify locally appropriate demand reduction actions to adequately respond to shortages. Water shortage contingency planning 8-3 Appendix D and Pages 8-3 to 8-5 64 x 8.4 Section 8.4 10632(a)(4)(C) Specify locally appropriate operational changes.
