Step 1: Modify the Baseline Amount if appropriate. Baseline Annual Water Use Amount as modified =_____ acre-feet Customer Baseline Amount

Annual Allotment Steps 2 & 3: Deduct the Percentage Curtailment (20 percent) from the Baseline Amount Annual Allotment = Baseline Amount X 80% = acre-feet The Annual Allotment is the amount of water to which Customer is entitled during a water supply shortage on an annual basis. This amount may be pro rated for a partial calendar year.

Monthly Distribution of Annual Allotment Consider seasonal use Savings from current drought measures Possible need for stricter measures for outdoor water use Possible projects planned for next year to reduce water use

Modification to the Baseline Amount – How does it work? Customer A baseline amount = 90 AF 20% reduction to baseline amount = 18 AF Annual allotment = = 72 AF Customer B baseline amount = 90 AF + 10 AF conservation savings = 100 AF 20% reduction to modified baseline amount of 100 AF =20 AF Annual allotment = 100 – 20 = 80 AF

Modification: Conservation Must have occurred in reference year Limited to programs implemented over the past 10 years Demonstrated savings –Permanent equipment or process change –Other measures – statistical analysis Documentation of measure implemented

Other Possible Modifications New development New industry Industry outage Documentation – LUEs, number of connections, industry water use from acceptable documents

Request for Variance to the Curtailment Amount Customer A – 90 AF baseline amount with 20% reduction = 72 AF allotment Variance request to waive or reduce the 20% reduction, cannot meet the 72 AF allotment Based on a threat to public health, welfare and safety
