3. CEHMM, not less than 3 days in advance, of any changes to prior notice of New Surface Disturbance; and, 4. CEHMM within 72-hours after Emergency Operations that result in New Surface Disturbance. Emergency Operations are those activities unexpectedly and urgently required to prevent or address immediate threats to human health, safety, property, the environment, or national defense or security. Withdrawers Water Withdrawer industry sector Participants (Water Withdrawer Participants) agree to implement the following Conservation Measures: A. Zone A Temporarily maintain minimum streamflow and curtail pumping in Zone A – should the flow fall below 9.3 cfs at the USGS gauge location at the CID dam. NMDGF recommends 3 cfs (Arm et al. 2014) absolute minimum flow for the Texas Hornshell, but 9.3 cfs is based on current minimum flow as established by water withdrawers in the area. However, the Technical Work Group, following the Governance process (Section II), will work with subject matter experts to determine minimum flow within five years of implementation of this CCAA. B. Zone B Within the and Delaware rivers (excluding Zone A in each), Blue Springs, – and their associated USGS 100-year floodplain: 1. Temporarily maintain minimum stream and cease pumping of water if minimum flow is reached. The Technical Work Group, following the Governance process (Section II), will work with subject matter experts to determine minimum flow within five years of implementation of this CCAA. C. Zone C - Ephemeral Drainages to the Black and Delaware rivers, including Owl Draw: 1. Temporarily maintain minimum stream flows and cease pumping of water if minimum flow is reached. The Technical Work Group, following the Governance process (Section II), will work with subject matter experts to determine minimum flow within five years of implementation of this CCAA. Agriculture and Agriculture and Ranching industry sector Participants (Agriculture and Ranching Participants) to implement the following Conservation Measures: A. Zone A - No New Surface Disturbance in Occupied Habitat within the Black and Delaware rivers as identified in Appendix B, corresponding to the limits of known populations identified for protection.
