Hydrology/Water Quality Clause Samples

Hydrology/Water Quality. Increased delivery and irrigation efficiencies: Tailwater Reduction

Hydrology/Water Quality. The proposed Agreement will not have any impact on water quality, and will not change the impacts identified in the City’s CEQA documents.

Hydrology/Water Quality. Prior to Grading Permit issuance and as part of the project’s compliance with the NPDES requirements, a Notice of Intent (NOI) shall be prepared and submitted to the State Water Resources Quality Control Board (SWRCB), providing notification and intent to comply with the State of California General Permit

Hydrology/Water Quality. Tailwater Reduction:

Hydrology/Water Quality. Soil Moisture Monitoring Increase delivery and irrigation efficiency:

Hydrology/Water Quality. Increased delivery and irrigation efficiencies Soil Moisture Monitoring Program Participation in reach-wide Diversion Management Plans Upgrade/repair/maintain diversion facilities Water exchanges 2.a. Upgrade/operate/repair/maintain diversion facilities and Diversion relocation/combination), o Assuming there is a temperature monitoring station in the vicinity of the south property line and upstream of the HIG Gravity Diversion (currently “HVR DS PL” fulfills that role), o Permittee may divert Clear Spring per the license, less any instream commitments exchanged for efficiency improvements in the Gravity Ditch, at the start of the irrigation season, o Annually, when 18°C MWAM is reached at the water temperature monitoring station (currently “HVR DS PL”), HIG will receive a volume of “Exchange” water from MWCD to substitute for the volume of Clear Spring being diverted at which time, o Permittee will cease diverting Clear Spring, o Permittee will divert the combined diversion amounts for HIG Gravity and Pump diversions at only the Gravity Diversion, o Annually, if below 18°C MWAM temperatures occur, nearing the end of the irrigation season (November 1), when air temperatures are averaging cooler, Exchange water may be curtailed and Clear Spring may be diverted at the HIG Pump Diversion. Time Frame: Within 5 years of ESP issuance. • See Diversion Combining Project, described above in Section E.3.a.

Hydrology/Water Quality. Thermal, Stage and discharge monitoring Hole in the Ground (HIG) Creek: a) If deemed feasible and beneficial to the Covered Species, the Permittee commits to designing, permitting and implementing restoration of HIG Creek on BSRWA. Upon completion of restoration activities (on both BSRWA and HIG Ranch) and if said activities address the water quality issues associated with this water, then the Permittee agrees to change the existing permissive CWC §1707 dedication of water rights associated with HIG Creek to a permanent dedication for the purposes of instream beneficial use. This would include the submission of necessary notifications to the ▇▇▇▇▇ and Shasta Valley Watermaster District that describes the intent to dedicate these water rights instream permanently. If implemented, the project could restore two miles of habitat on HIG Creek; or b) If the above enhancement proposal is deemed infeasible and/or if HIG Creek water is still deemed an impact to the Upper Shasta River or the spring near the HIG mouth, alternatives shall be explored to minimize the negative water quality effects of HIG Creek entering the Upper Shasta River. If a feasible project can be developed, Permittee will pursue the project. The completed implementation schedule of this action is currently estimated to occur within 5 years of the signing of this Site Plan Agreement, contingent on funding and permitting.

Hydrology/Water Quality. Construction of the HRS would occur within the West End property and the extent of construction would be less than what would have been required for the construction of the food waste preprocessing facility. Construction-period water quality impacts would be similar to or less than those identified in the 2011 EIR. The HRS would not increase impervious surface area as compared to the proposed level of development envisioned in the 2011 EIR, and thus would not increase the amount of runoff into existing storm drains. The 2011 EIR noted the need for expansion of the stormwater collection system if the stormwater runoff from the West End property would be conveyed to the MWWTP; however, stormwater from the proposed HRS would continue to be conveyed to the existing stormwater collection system as it is now and thus Mitigation Measure HYD-3: Prepare and Implement a Comprehensive Drainage Plan, is not applicable. No operational changes to stormwater runoff or water quality would be expected. Mitigation Measure HYD-5: Prepare and Implement a Tsunami Response Plan, pertains to the entire MWWTP and would not be affected by construction and operation of the HRS. The HRS would not cause effects that were not analyzed in the 2011 EIR. No new mitigation measures would be required, and impacts would remain less than significant. HYD-5 requires EBMUD to prepare and implement a Tsunami Response Plan for the MWWTP site that defines emergency response and coordination procedures. The Tsunami Response Plan shall contain information specific to actions that may be necessary related to receipt of a tsunami watch, warning, or as a result of an actual tsunami along the San Francisco Bay.
