The District's Schedule of Fees Ordinance is subject to change by the County Board of Supervisors. The Board typically considers changes in the Schedule of Fees Ordinance to take effect at the beginning of each fiscal year (July 1). Should the borrow fee rate be adjusted at any time during the life of this permit In accordance with changes to the Schedule of Fees Ordinance, the Permittee shall have the right to continue soil removal based on the new rate or request cancellation of their permit prior to the effective date of the new rate. Upon cancellation, the Permittee shall be responsible for restoring the work area to the satisfaction of the District prior to vacating District right-of-way. The District shall not be responsible for any impact to contractual obligations the Permittee may have with any clients as a result of revisions to the Districts Schedule of Fees Ordinance. 44. The Permittee is hereby advised that the District's inspector shall make routine, periodic visits to the construction site commencing upon the date of permit issuance. Such site inspections shall be performed to ensure that permit activities have not been initiated without proper notification to the District. As such, the District shall have its inspector charge the appropriate time for such site visits, whether work is being performed or not, and inspection fees for the permit may be assessed accordingly based on the time necessary to conduct the necessary site visits. 45, It shall be the responsibility of the Permittee to ensure that all applicable Federal, State and local regulatory requirements are adhered to during the entire term of this permit, �ov MU SHEET 8 OF 8 EXHIBIT "A" ATTACHED TO Peps a of a UNITED STATES ENVIRONMENTAL PROTECTION AGENCY + REGION IX 75 Hawthorne Street San Francisco, CA 94105 SENT VIA EMAIL AS PDF April 26, 2017 Mr. Kevin Blakeslee Deputy Director, Flood Control San Bernardino County Flood Control District Department of Public Works 825 East Third Street San Bernardino, CA 92415-0835 Dear Mr. Blakeslee: Subject: Startup and Operational Discharges to the Cactus Avenue Flood Control Basins We have reviewed the March 3, 2017, letter from West Valley Water District (WVWD) to the San Bernardino County Flood Control District regarding planned discharges of treated water from W V W D's Groundwater Wellhead Treatment System Project into Cactus Avenue Flood Control Basin #2. We understand that the Flood Control District operates the Cactus Basins. The letter states that discharges are planned during initial plant startup and operation of two of W V W D's water treatment systems constructed to remove pemhlorate from the groundwater. W V WD constructed and began operation of a Fluidized Bed Reactor (FBR) in 2016 and is constructing a Fixed Bed Reactor (FXB). The letter estimates the timing and volume of future discharges as follows. - 246 AF from March through May 2017, associated with FBR operation - 779 AF from May through December 2017, associated with FBR operation and FXB startup - 733 AF annually after 2017, associated with FBR and FXB operation The discharged water is expected to recharge the Cactus Basins and infiltrate into the underlying groundwater. The majority of the water produced by the FBR and, after startup, by the FXB is or will be distributed to W V W D's residential and business customers. Although the discharge volumes are higher than W V WD previously estimated, we do not expect the discharges to have a significant effect on the distribution or movement of contaminated groundwater in the Rialto -Colton groundwater basin. The Cactus Basins are located near the western edge of the groundwater plumes associated with the Rockets, Fireworks, and Flares Superfund Site (formerly known as the B.F. Goodrich Superfund Site). SHEET 1 OF 4 EXHIBIT "B" ATTACHED TO CONTRACT NO.16-2545*A7 EPA reached the same conclusion about past discharges associated with the project. We have noted in past letters that the shallow groundwater beneath the Cactus Basins is not known to be contaminated and that significant groundwater contamination near the Basins (i.e., contaminant concentrations exceeding Maximum Contaminant Levels) first appears deeper in the aquifer (e.g., at more than 100 feet below the water table at nearby groundwater monitoring well 1 S/5W-3A). This is still the case. We expect that the planned discharge will have a negligible effect, if any, on this deeper groundwater.

The TM was prepared by the WVWD and the Model Report was prepared by Geoscience. The TM was an update to WVWD's October 2012 TM, and provided further technical analysis in response to the concern of the San Bernardino County Flood Control District (SBCFCD) that WVWD's proposed long-term use of the SBCFCD's Cactus Basins #1 and #2 for the discharge of treated groundwater may adversely affect the movement of a Perchlorate and trichloroethylene (TCE) contaminant plume that is present in the groundwater that underlies the basins. WVWD states that Geoscience's Model Report is a consolidation and comparison of various model runs of different groundwater models that have been developed over the past decade, and in collaboration among the San Bernardino Valley Municipal Water District, WVWD, the Goodrich Corporation, the cities of Rialto and Colton, USEPA, CH2MHill consultants and the U.S. Geological Survey. Based on the modeling results, the data from previous discharges to Cactus Basins #1, #2, and field measurements of groundwater elevation, WVWD and Geoscience conclude that: 1. "There is no significant change in the size of the geographic footprint of the Perchlorate plumes with or without recharge at the Cactus Basins, but concentrations are decreased from dilution;" 2. "Water levels increased up to 2-ft in the vicinity of the recharge ponds as a result of recharge versus no recharge. Water levels due to recharge were imperceptible elsewhere in the Basin;" 3 "The model predictive results show no anticipated significant groundwater contamination impacts from the proposed Project, suggesting that no additional mitigation measures are needed beyond those that have been previously planned and are in place."

We have reviewed the data and calculations in the attachments to WVWD's TM. IWVWD states that the two downgradient municipal supply wells (Rialto #6 and WVWD #11) that are being pumped (to generate water for the treatment and subsequent discharge to Cactus Basin #2) will capture the majority of any localized recharge that may result from percolation of the clean, treated water into Cactus Basins #1 and #2. Monitoring data from (USGS Cluster Well 1S/5W-3A) indicate that the shallow groundwater underlying the Cactus Basins is not severely impacted by the perchlorate and TCE plume. Sampling results from July 2016 revealed that perchiorate was detected at 3.1 micrograms per liter (Ng/!) and TCE was not detected at a depth of 410 feet below ground surface (bgs). Higher Concentrations of perchlorate (248 pg/l) were detected at a depth of 510 bgs, with TCE detected at 17.6 pg/I. Based on the percolation data and infiltration calculations, and considering the depth of the plume below the groundwater table, we do not believe that the limited volume and the anticipated intermittent occurrence of the discharge to the two basins will adversely impact the movement of the perchlorate plume. Based on our communications with Ms. Joanne Chan, Operations Manager for WVWD, we understand that on March 3, 2017, WVWD submitted a written request to the County to amend their existing spreading agreement to allow higher discharge volumes to the Cactus Basins, from 128 acre-feet to 800 acre-feet per year. This is believed to be sufficient to accommodate discharge of the higher than expected effluent volume from the Fluidized Bed Reactor (FBR) to the Basin, as well as volumes required for the Fixed Bed Reactor (FXB) system during the demonstration phase in the summer of 2017. WVWD is currently authorized to discharge up to 2,88 million gallons per day of treated groundwater to Cactus Basin #2 under the terms and conditions of Regional Board Order No. R8-2012-0027. Based on our evaluation of the TM and groundwater modeling simulations for the Rialto -Colton Basin. we do not have any objections regarding the proposed increase in discharge volume to the Cactus Basins.
