Title: Item 20- Discuss Water Supply Concepts, Including Reclamation
1Item 20- Discuss Water Supply Concepts,
Including Reclamation
- MPWMD Board Meeting
- March 15, 2004
- Staff Contact Henrietta Stern
2Water Sources Reviewed
- Pebble Beach Wastewater Reclamation Project --
benefited properties - PB Reclamation -- MPWMD share
- Paralta well community drought reserve
- Conservation savings
- Aquifer storage and recovery (ASR)
- Seaside Basin in-lieu recharge.
3Important Reminders
- All Cal-Am water comes from Carmel River Basin or
Seaside Coastal Subareas there are no other
sources at this time. - SWRCB Order 95-10 controls use of Carmel River
(11,285 AFA diversion limit one-for-one
replacement) - Seaside Basin hydrologic trends and ongoing
litigation potentially limit use.
4Pebble Beach Reclam. Project Benefited Properties
- SWRCB recognizes up to 380 AF that can be added
to 11,285 AFA diversion limit - Water goes only to benefited properties, and only
in Del Monte Forest - Ordinance No. 109 in progress to help fund Phase
II project expansion/improvements to maximize
reclaimed water production and minimize need for
Cal-Am water.
5Pebble Beach Reclam. Project MPWMD Share
- Up to 420 AF to MPWMD (not recognized by SWRCB to
add to 11,285 AF limit) - Assumes 800 AFA Cal-Am production is replaced
280 AFA shortfall estimated - No more than 140 AFA should be released (420
280 140) this would be Carmel River water - Need CEQA review, based on Ordinance No. 84
litigation.
6Paralta Well Community Drought Reserve
- No physical reserve from Paralta Well ever
existed 1,000 AFA used from beginning - Physical limits to Cal-Am system prevent greater
use of Paralta well - Seaside Basin issues stymie use
- Formal MPWMD policy against allocation of 385 AF
reserve is presently in effect.
7Conservation Savings
- MPWMD conservation program since 1987
- 2,040 AF estimated as permanently saved 20
savings despite 16 increase in customers - Conservation enables compliance with Order 95-10
limits - Conservation is affected by weather, emotions
- How much more savings without hardship?
- Recommend not using conservation savings.
8Future Water Source -- ASR
- Aquifer storage and recovery is promising
- 941 AF injected and 440 AF recovered to date
- Aquifer recharge and water quality benefits
- Up to 1,300 AF with minor improvements to Cal-Am
system larger sizes too expensive - Need many permits for long-term program MPWMD in
progress with water rights. - Worthwhile to pursue, even with Order 95-10.
9Future Source Seaside Basin In-Lieu Recharge
- MPWMD asked SWRCB to approve using more Carmel
River water in wet years to let Seaside rest
and recharge Seaside could safely produce in dry
years with less impact to river. - SWRCB staff rejected MPWMD request for temporary
relief in letter dated January 14, 2004
(distributed at January 29, 2004 meeting). - MPWMD continues to pursue concept through
long-term Petition for Change.
10Summary of Concepts
- Stop bottom up planning based on uncertain
water sources recognize existing top down
limits (15,285 AFA) (Note 14,785 AFA production
is less risky.) - Recognize misconceptions about many water
sources. All Cal-Am supply comes from Carmel
River Basin and Seaside Basin Coastal Subareas.
11Discussion Concepts, continued
- 3. Prepare an EIR on Water Allocation Program
based on existing limits and recent trends EIR
must define and evaluate proposed project and
alternatives. - 4. Importantly, the SWRCB can change the 11,285
AFA limit. It is not a water right.
12Basic EIR Questions
- How much water is available to allocate? Relates
to risk of exceeding SWRCB 11,285 AFA Carmel
River limit and protecting Seaside Basin. - Who gets how much water? Distribution of water to
jurisdictions affects cumulative growth impacts
(e.g., traffic, air quality, biology). - How to handle 156 AF existing tabulated
jurisdiction allocations? Affects how much water,
if any, is available for new uses.
13Specific EIR Questions
- How much water is used from Carmel River and
Seaside Coastal Subareas now? - Compare actual use to SWRCB limit on Carmel River
and Seaside production goals. - Assess wiggle room how much to allocate and
not go over 11,285 AF Carmel River limit? - Policy trade-off of economic benefits versus risk
of more rationing, Seaside Basin impacts, or
exceeding SWRCB limit (large fines).
14EIR Questions, continued
- 5. Should military and District community reserve
be added as jurisdictions? - 6. Should all or some of the existing 156 AF on
MPWMD books be preserved? Under what conditions?
- 7. Who pays for EIR funding issues. Joint
funding a possibility?

16Specific Allocation Concepts
- Higher the allocation, the higher the risk of
exceeding 11,285 AFA limit. - 560 AF is higher risk maximum based on
1998-2003 Carmel River production average. - 260 AF is intermediate risk maximum based on
1997-2003 Carmel River production average. - 100 AF is lower risk maximum based on closest
Carmel River production to SWRCB limit, except
1997. - Zero allocation is safest (still some risk).
17Preserve 156 AF for Jurisdictions or Not?
18Allocation Sources
- Actual drinking water comes from Carmel River
(subject to SWRCB restrictions) and Seaside
Coastal Subareas. - Sources such as 140 AF from MPWMD share of
Pebble Beach Reclamation Project is not a
separate supply source, and is not recognized by
SWRCB.
19Overview of January 28, 2004 TAC/PAC Meeting
- The concept of 140 AF allocation was suggested by
Chairman Edwards. - Did not specify whether this would be in addition
to or instead of the 156 AF currently tabulated
for jurisdictions. - TAC/PAC did not have a recommendation on
allocation issues at the meeting.
20Recommended Board Action
- Discuss concepts and provide direction on key
questions. - At this time, consider providing direction on
process and committee/community involvement in
developing proposals and alternatives for an EIR.
