The Los Angeles Department of Water and Power (LADWP) recently launched the Industrial Stormwater Rebate Program (ISRP),a program designed to help achieve the goals of Mayor Garcetti’s Sustainable City Plan, which include cutting the purchase of imported water in half by 2025 and locally sourcing half of all LA’s water by 2035.
Approved on March 13, 2018, the purpose of the ISRP is to incentivize Industrial General Permit (IGP) facility owners and operators to capture stormwater runoff for onsite use or infiltration for groundwater recharge. The anticipated incentives in the ISRP amount to $1,100 per acre-foot per year of water supplied for groundwater recharge and $1,550 per acre-foot per year of water capture and used onsite. Both incentives were calculated over a 30-year period, representing the anticipated design life of the Best Management Practices (BMP). The $1,100 and $1,550 values were established by LADWP’s Stormwater Capture Master Plan and were based on the Metropolitan Water District (MWD) projected long-term rates for imported water.
Initial ISRP funding includes up to $800,000, which is projected to cover anywhere from 6 to 12 applicants. Based on the first year alone, the ISRP could result in the capture of up to 4,000 acre-feet (1,303,315,200 gallons) per year of stormwater for infiltration into the San Fernando Groundwater Basin. The amount of incentives available in subsequent years will be determined based on demonstrated program performance and projected participation.
Incentive Reimbursement Process – Each applicant’s incentive is established as follows:
- Applicant determines if the facility qualifies for incentive based on established qualifying criteria.
- Applicant fills out, prints, sign, and submits the application to Water Resources’ Watershed Management Group (WMG) along with a concept proposal and calculations for the design capture volume.
- WMG staff evaluates the proposal based on selection criteria, conducts a jobsite visit if necessary, and respond to the applicant with preliminary approval along with the amount of incentive funds to be paid based on calculated capture volume. If the application is rejected, WMG staff will state reason(s) for the rejection.
- Approved applicants will prepare design plans, stamped and signed by a certified Professional Engineer licensed in California, and submit to the City as part of the plan, checking, and approval process.
- Upon acceptance by the City’s Bureau of Sanitation plan checker of the proposed BMPs, LADWP will issue a formal approval detailing the requirements of the program and any agreements with the property owners.
- Participants must enter into an agreement with LADWP and comply with its terms.
- Incentive funds will be distributed on a reimbursement basis, following the first year of operation and first annual reporting to the SWRCB SMART system.
