water quality sampling results, CMWD will submit a Notice of Intent (NOI) to

the RWQCB for Discharge of Groundwater to Surface Water. For the purposes

of bidding, use the following information:

Estimated pumping volume:

Conservative volumetric estimates for dewatering pumping were calculated using surface

water discharge based on the 2018-19 water year, historic hydrology records, and

understanding of the local hydrogeology. The estimated discharge volume of

groundwater is approximately 485,000 to 1,292,000 gallons per day (337 – 898 gallons

per minute), with an estimated average of 889,000 gallons per day (617 gallons per

minute).

Treatment requirements:

Based on available analytical data, treatment is required for DEHP [Di(2-ethylhexyl)

phthalate], in accordance with the General Permit (Order R4-2018-0125). Assume

treatment is required for the pending analytes (metals and miscellaneous pollutants). The

attached list of analytes (part of the NOI) compares the analytical results to the General

Permit screening levels. Note the blanks in the quantitation column, which identifies the

pending analysis. Also attached is a draft figure to present the approximate intake and

discharge locations as well as the planned treatment system location (these locations

were chosen based on site knowledge, but are subject to change based on site conditions

and project needs).

1.0 Introduction

This document provides the Stream Diversion Plan for the Robles Forebay Restoration Project, located at Casitas Municipal Water District’s (CMWD) Robles Diversion Facility along the Ventura River in Ojai, California. This Plan was prepared in accordance with the Los Angeles Regional Water Quality Control Board’s 401 Water Quality Certification, an application for which was submitted May 8, 2019.

The Robles Diversion Facility was affected due to the Thomas Fire. The Forebay upstream of the facility filled with sediment which impacts the ability of CMWD to regulate the amount of water available to divert to storage and discharge down the fish ladder. This project seeks to remove approximately 50,000 cubic yards of sediment from the Forebay and place it downstream of the timber cutoff wall in August/September 2019 for transportation by future storm events. In future years the amount of sediment removal will vary and is expected to range between 20,000 and 50,000 cubic yards annually. The proposed stream diversion and water quality monitoring are described in the following sections.


Page 2

2.0 Diversion Plan

The area in the Robles Forebay is usually dry by June each year. Due to the heavy rains in winter 2019, the late storms in May 2019, and the lack of mature vegetation in the watershed due to the Thomas Fire, this area is still saturated and has active flow. The diversion is needed to allow the Forebay to dry out sufficiently so sediment removal can be performed. Should stream flow persist in August 2019, when the project is scheduled to begin, the stream diversion will remain in place throughout sediment removal activities in the Forebay, to divert stream flow around the work area. Figure 2-1 shows the elements of the water diversion. If the river is still flowing, a sandbag cofferdam will be erected to divert surface water into a 24-inch diameter high-density polyethylene (HDPE) pipe. The inlet of the diversion will be located approximately 1,000 feet upstream of the Robles Diversion Facility.

The pipe will convey water downstream approximately 800 feet and will be directed in to the high flow exit of the fish ladder. The water will travel down the existing five-foot wide concrete channel and exit into the screen forebay of the fish passage. At this point, the water has rejoined the normal pathway through the fish passage.

The pipe is sized to handle the current flow rate of approximately 15 cubic feet per second (cfs) while maintaining a velocity of no more than approximately six feet per second (fps). Fish may still pass should they choose to move upstream. The diversion pipe will have a cone shaped metal grate installed on the inlet as shown in Figure 2-2. The grate will keep debris from clogging the pipe and humans from attempting to or accidentally entering the pipe, but will still allow fish to move freely through the device.

The contractor will access the site from the end of Rice Road and use the existing access road to cross

the River. In the event there is active flow across the low-flow weir crossing, steel plating will be placed

across the weir as it is a steep slope. The HDPE pipe will be fused together in the upland disturbed area

west of the facility headworks and the contractor will attach a strap to the pipe and use an excavator to

put the pipe in place. The contractor may need to use the excavator to move some larger rocks out of

the way in the stream channel.

2.1 Best Management Practices

The following Best Management Practices will be implemented:

The District intends to implement the project between August 15 and September 30 each year outside the bird nesting season (typically February 1 – August 1) and winter rainy season (typically November – April) to avoid the conditions in which special status species may be present.

Project activities occurring between February 1 and August 31 will involve a qualified biologist to survey the project site within five (5) days of project commencement for nesting birds. Should any protected breeding/nesting birds be observed, the biologist will flag the area and implement appropriate avoidance measures to preclude impacts.

Immediately prior to ground disturbance, the impact areas and channel will be surveyed to ensure no sensitive terrestrial and aquatic species have entered the work area.

During ground disturbance activities, a biological monitor will be on site to ensure agency mitigation requirements are met.


Page 3

The clean-up of any accidental spill will begin immediately pursuant to all relevant hazardous materials regulations. If the spill could affect downstream water quality or impact special status resources, the appropriate regulatory agencies will be notified to determine the appropriate course of action.

All trash will be properly contained and removed from the work site daily. Any construction materials that could potentially wash downstream will be removed from the project site prior to inundation by high flows. When operations are completed, any excess materials or debris will be removed from the work area.

Any material/spoils generated from project activities will be located away from jurisdictional areas and protected from stormwater run-off using temporary perimeter sediment barriers such as berms, silt fences, fiber rolls, covers, sand/gravel bags, and straw bale barriers, as appropriate.

Any spillage of material will be cleaned up immediately and any contaminated materials will be properly disposed.

Staging and laydown areas shall be unvegetated areas and previously disturbed sites.

All vehicles and equipment shall be in good working condition and free of leaks. The contractor shall prevent oil, petroleum products, or any other pollutant from contaminating the soil or entering a watercourse (dry or otherwise). When vehicles or equipment are stationary, mats or drip pans shall be placed below vehicles to contain fluid leaks.

All re-fueling, cleaning, or maintenance of equipment will occur at least 100-feet from potentially jurisdictional waters.


Page 4

3.0 Preconstruction Baseline Monitoring

Baseline water sampling for dissolved oxygen, pH, turbidity, and temperature will be conducted no more than 24 hours prior to the commencement of in-river water activities to determine the baseline parameters at the site. The data will be recorded on a Water Quality Monitoring Log.

The baseline sampling location will be within the low flow channel above and below the project impact area. All equipment utilized for sampling will be utilized and calibrated per the manufactures’ specifications. Sampling equipment will include a dissolved oxygen meter, a waterproof pH/temperature meter, and a portable turbidity meter.


Page 5

4.0 Construction Monitoring and Reporting

All monitoring and reporting will be done in compliance with the 401 Water Quality Certification to be issued by the RWQCB for the project.

4.1 Sampling Locations

The upstream and downstream sampling locations will be determined prior to and immediately following the construction of the diversion and photographs will be taken. The upstream location will be immediately upstream of the diversion where water enters into the diversion pipe and the downstream point will be immediately downstream of the high flow fish exit.

4.2 Sampling

Per typical 401 Water Quality Certification requirements, daily testing will be conducted for dissolved oxygen, pH, turbidity, and temperature for the first week and weekly thereafter. Oil and grease will be monitored visually on a continuous basis.

Samples will be compared to receiving the following water quality standards:

Dissolved oxygen (DO): concentration of a single sample shall not be less than 5.0 milligrams per liter (mg/l) except when natural conditions cause lower concentrations. The DO content of all surface waters designated as COLD shall not be depressed below 6 mg/l as a result of the diversion.

pH: shall not be depressed below 6.5 or raised above 8.5 as a result of the diversion. Ambient pH levels shall not be changed more than 0.5 units from natural conditions as a result of waste discharge.

Turbidity: Downstream total suspended solids (TSS) shall be maintained at ambient levels. Where natural turbidity is between 0 and 50 Nephelometric Turbidity Units (NTUs), increases shall not exceed 20 percent; where natural turbidity is greater than 50 NTUs, increases shall not exceed 10 percent.

4.3 Corrective Measures for Non-compliance

If sampling indicates non-compliance with the thresholds described above the situation will addressed immediately. Corrective actions will include ensuring compliance with all the Project Implementation Conditions in the project’s 401 certification and/or adjusting Best Management Practices for erosion control if applicable. If water quality objectives are not met by these means, a Baker tank will be considered and discussed with the Water Board to allow for settling of sediment and/or removal of dewatered water from the site for disposal. Any non-compliant readings will be recorded in the daily log with a description of the corrective actions taken.

4.4 Reporting

A report will be prepared and submitted to the Los Angeles Regional Water Quality Control Board by the 15th day of each subsequent sampling month, after the diversion is constructed and/or dewatering begins. The report will provide:


Page 6 Date and time samples are taken

Location(s) of sampling

A narrative description of diversion function and stage

A table with sampling results for dissolved oxygen, pH, turbidity, oil/grease, and analysis discussion

Corrective actions taken, if any

Photos of the sampling points and any pertinent photos of the diversion

The In-Water Work/Diversions Water Quality Monitoring Report will be submitted to the Los Angeles Water Board staff within three working days following completion of the stream diversion.
