  1. MONTERY COUNTY2005 GENERAL PLAN UPDATESTUDY SESSION – DOMESTIC WATERMay 19, 2005

  2. Feasibility and Application Completeness Requirements • Source Water Quality Analysis • Meets all Title 22 water quality parameters. • Technical, Managerial, and Financial (TMF) Feasibility and Capacity • A Water Consolidation or “Can and Will Serve” Letter • Water Use and Nitrate Impact Questionnaire • Source Capacity

  3. Water QualityBased on Level of Public Health Risk(MCC 15.04.090, H&SC 116555, CCR Title 22) • Acute – High Public Health Risk • Immediate illness could result in death. • Chronic – Moderate Public Health Risk • Prolonged exposure shown to cause illnesses which can lead to death. • Aesthetic – Low Public Health Risk • Unpleasant taste or odor, staining of clothing and fixtures.

  4. Water Quality Acute Risk Nitrates • Most common contaminant in Monterey County. • 45 mg/l (MCL) maximum contaminant level. • Infants (“Blue Baby Syndrome”) , elderly, people who are anemic are susceptible

  5. Nitrates Acute Risk • When the nitrate level in the water supply exceeds the maximum contaminant level, then treatment is not acceptable due to: • The risk of failure. • Must have regular maintenance on the treating device and is only effective to a certain level. The treatment is expensive $10K -$20K for a typical 4 connection system. • The disposal of waste products is problematic with Regional Water Quality Control Board.

  6. Nitrate Monitoring Results

  7. Chronic Risk Prolonged Exposure • Naturally occurring contaminants in groundwater such as arsenic, and fluoride which exceed the MCL. • Subdivision is approvable. There is approved treatment technology. $10K - $100K • Disposal of brine is problematic (hazardous material) • All TMF requirements. • Non-naturally occurring contaminants such as Cadmium and Chromium which exceed the MCL. • Subdivision is not approvable. There is no approved treatment technology.

  8. Technical, Managerial, and Financial (TMF) Requirements(MCC15.040.040, MCC 19.03.015, H&SC 116540) (1 0f 2) • Source Water Assessment Program (SWAP) • Map of potential contaminating activities • Type of ownership • Contract for Certified Operator • How professional services will be provided • Budget projection • Equipment replacement fund • Capital improvement plan

  9. TMF - Water Rights(MCC 15.04.040 and 19.03.015l, H&SC 116555) (2 of 2) • Title Report (if necessary) • Deed of trust for well • Documentation of surface water rights • Identification of any other water right issues

  10. Water System Consolidation Letter & Valid “Can and Will” Serve Letter(MCC 15.04 and H&SC 116540) • Includes identification of existing systems within one mile. • Feasibility of incorporating into an existing system. • Feasibility of being owned, operated or managed by a satellite agency. • Documents the ability to serve with an expiration date in place.

  13. RECOMMENDATIONS DOMESTIC WATER AND LAND USE PERMITTING

  14. PRIVATE WELLS FOR DOMESTIC USES 1. All new wells for domestic uses must meet minimum quantity requirement of 3 gpm after a maximum 72-hour pump test. In hydrogeologic areas where data has been previously developed, the pump test may be reduced. 2. Bulk hauled water is not considered an approvable supply for new construction. 3. New development on existing lots of record must have a determination of water quality via a one time biological and chemical analysis of primary and secondary constituents. A noticing process would be required so that future owners of the lot would be informed of the water quality. 4. Continue the requirement that lots served by a well and an onsite wastewater treatment system must be a minimum of 2.5 acres.

  15. WATER SYSTEMS 5. Require consolidation of water systems for new development with existing utilities in community areas and rural centers. In all other planning areas, the formation of new mutual water systems would be discouraged by requiring the creation of satellite systems owned and operated by existing entities (i.e., PUC Utilities, Community Service Districts) where feasible with the appropriate Technical, Managerial and Financial, (TMF) feasibility assurances. 6. To assure water quality and improved basin-wide management of groundwater resources, water system owners and purveyors shall retain all water rights for new lots created through minor and standard subdivisions.

  16. LAND USE PERMITTING(1 OF 3) • The County shall continue to require that new development have a long term sustainable water supply. This shall not be a factor in determining a project complete, but will be a critical factor in determining whether a project deemed complete can be recommended for approval. 8. Long Term Sustainable Supply should be determined on a basin by basin basis: • Projects in Zone 2C shall be considered to haves a long term sustainable supply • Projects in basins under the purview of the Pajaro Water Management Agency shall be evaluated in terms of the implementation of that agency’s CIP • Projects in the area managed by the Monterey Peninsula Water Management District shall be governed by State Order 95 • The Seaside Basin shall be considered not to have a long term supply at this time • Long term supply in the Toro Basin (t.b.d.)

  17. LAND USE PERMITTING(2 OF 3) 9. As part of the determination of long term supply for individual projects, the County shall encourage the reduction of water usage on a property in the permitting process. For the purpose of determining baseline, documented water usage for 10 out of the past 20 years shall be calculated. A minimum of 30% savings over baseline shall be required. 10. Water quality shall be a key additional determinant of long-term sustainable supply. 11. A will serve letter from an existing water purveyor verifying that financial and infrastructure commitments have been completed will also be required.

  18. LAND USE PERMITTING(3 OF3) 12. In Community Areas, regional impacts may be addressed via impact fees tied to a CIP for new development. 13. Outside Community Areas: • Require connection to a water system or establishment of a satellite to an existing water system that has the appropriate TMF. • Regional impacts may be address via impact fees tied to a CIP for new development. However, outside community areas the CIP shall have Tier 2 priority.

  19. WASTEWATER TREATMENT AND DISPOSAL(1 0f 2) 14. Require new development to consolidate wastewater collection, treatment and disposal systems of services to existing systems where feasible. The county shall not allow the use of package plants when connection to a regional facility is feasible. 15. Prior to deeming an application for development complete, proof of wastewater treatment infrastructure feasibility must be approved. Proof of wastewater treatment infrastructure would include an evaluation of technical, managerial, and financial capability of the responsible entity for operating the facility. 16. Wastewater treatment facilities must be built and approved prior to the issuance of building permits.

  20. WASTEWATER TREATMENT AND DISPOSAL (2 of 2) 17. New wastewater treatment facilities shall meet tertiary or advanced tertiary treatment standards in coordination with the Central Coast Regional Water Quality Control Board. 18. All community wastewater systems will be operated by duly constituted public or private entities including independent Community Services District or Community Facilities District, but excluding County Service Areas or County Sanitation Districts. 19. Wet weather storage capacity of 120 days is required for treated sewage. 20. A minimum lot size of one acre will be required for lots served by a community water system and where sewage disposal is by an onsite wastewater treatment system.

  21. SOLID WASTE • The county shall adopt a Landfill Buffer Zone Ordinance
