PROJECT OVERVIEW • Regional advanced purified water project including an advanced treatment facility complex (ATF; including an advanced purified water storage tank, an equalization basin, a pump station), pipelines, injection wells, monitoring wells, and one new production well • Multi-agency collaboration: • City of Pismo Beach • City of Grover Beach NCMA Agencies • City of Arroyo Grande • Oceano Community Services District • South San Luis Obispo County Sanitation District (SSLOCSD) PAGE 12 PAGE 12

PROJECT COMPONENTS (CONT.) PAGE 15 PAGE 15
ADVANCED TREATMENT FACILITY COMPLEX • Proposed site: 980 Huber Street, Grover Beach(APN 060-543-016) • Approximately 1.5 acres of land • Existing use: several unpaved storage yards for vehicles, equipment, and containers • Will treat water from Pismo Beach and SSLOCSD Wastewater Treatment Plants • Initial treatment capacity of 1.3 million gallons per day (Phase I) with final treatment capacity of 5.4 million gallons per day (Phase II) • Includes staff support facilities (offices, restrooms, break room, etc.) • Appurtenant structures: • Equalization basin • Advanced purified water storage tank • Pump station PAGE 16 PAGE 16

ULTRAVIOLET/ADVANCED OXIDATION PAGE 20 PAGE 20
DISCHARGE OF REVERSE OSMOSIS CONCENTRATE • Reverse osmosis process produces a waste water stream (concentrate) in addition to the purified water • Concentrate will be discharged via existing Pismo Beach/SSLOCSD WWTPs ocean outfall pipeline • Must be compliant with City of Pismo Beach and SSLOCSD National Pollutant Discharge Elimination System (NPDES) permit requirements PAGE 21 PAGE 21
Pismo Beach WWTP Pismo and SSLOCSD WWTPs are connected via the existing outfall line Concentrate discharge to ocean outfall SSLOCSD WWTP PAGE 22 PAGE 22
PAGE 23 PAGE 23
INJECTION AND MONITORING WELLS • Seven injection wells • 12 inches in diameter • 200 to 600 feet in depth • Ten monitoring wells • Footprints: • Up to 3,000 square feet per injection well (conservative assumption of footprint) • 25 square feet per monitoring well • Heights: • 6 feet for injection wells • Flush-mounted for monitoring wells PAGE 24 PAGE 24
PIPELINES • Four sets: 1. Convey secondary treated effluent from the existing Pismo Beach WWTP discharge pipeline to the ATF complex 2. Convey secondary treated effluent from the SSLOCSD WWTP to the ATF complex 3. Convey advanced purified water from the ATF complex to the injection wells 4. Convey concentrate from the ATF complex to the existing WWTP discharge pipeline • Approximately 6 to 24 inches in diameter • Primarily in existing rights-of-way • Will require drilling under the Union Pacific Railroad track • Will require work within the Oceano County Airport PAGE 25 PAGE 25
WELL AND PIPELINE LOCATIONS Five injection wells in Coastal Dunes RV Park and Campground Two injection wells at SSLOCSD Wastewater Treatment Plant property PAGE 26 PAGE 26
NEW PRODUCTION WELL • Location is yet to be determined – likely to be in Grover Beach • Intended to optimize groundwater pumping • Will be owned by City of Pismo Beach • 14 inches diameter • 300 to 600 feet in depth • Up to 3,000 square feet at surface (conservative assumption of footprint) PAGE 27 PAGE 27
INCREASED GROUNDWATER PUMPING Acre-Feet per Year 2018 Levels 764 Total Adjudicated Amount 4,330 for Urban Uses* 3,566 Net Increase *Note: There will be no increase in the groundwater allocations for any of the NCMA agencies. PAGE 28 PAGE 28
AGRICULTURAL IRRIGATION • Potentially a supplemental (not primary) use of advanced purified water • Will require pipelines between the ATF complex and agricultural lands to the south of Oceano • Exact locations are yet to be determined PAGE 29 PAGE 29
CONSTRUCTION PHASING • Phase I: • Five injection wells (IW-1, IW-2A, IW-3, IW-4, and IW-5A) • Ten monitoring wells • Water distribution pipelines • ATF complex with initial capacity to treat flows from Pismo Beach Wastewater Treatment Plant • Phase II • Two injection wells (IW-2B and IW-5B) • Expansion upgrades to the ATF complex with full capacity to treat additional flows from SSLOCSD Wastewater Treatment Plant • Potentially agricultural irrigation pipelines PAGE 30 PAGE 30
REGULATIONS FOR RECYCLED WATER • California Code of Regulations Title 22, Division 4, Chapters 1-3 • Regulations on use of recycled water for a range of purposes, including groundwater replenishment/indirect potable reuse and agricultural irrigation • Requires at least two months of travel time between injection wells and drinking water wells to allow for monitoring and response if needed PAGE 31 PAGE 31
SUMMARY OF THE ENVIRONMENTAL IMPACT REPORT 32 PAGE 32
EIR APPROACH • Hybrid Project/Program EIR • CEQA-Plus for SWRCB Clean Water State Revolving Fund Loan Program application • Project-level for Components with Known Locations: • Injection and monitoring wells • Water distribution pipelines • Advanced treatment facility complex • Discharge via ocean outfall • Program-level for Components with Unknown Locations: • New production well • Agricultural irrigation pipelines PAGE 33 PAGE 33
