BACKGROUND
The Final Tract Map for Tract No. 69164-01, an exhibit of which is attached hereto, has been
reviewed by staff and found to be in substantial conformance with the principles and standards
required by the Unified Development Code and State Subdivision Map Act. It was approved as a
tentative tract map by the City Council on April 26, 2011. The Final Tract Map consists of 18
lots, is approximately 29.13 acres, and is located on the east side of the City of Santa Clarita
(City). Consistent with the original entitlement, the Final Tract Map allows for 509 residential
units, 350,100 square feet of commercial development, a 622 -space parking structure, and a
community garden. In addition, the water reclamation plant (Water Factory) will be constructed
within Lot 1 of Tract No. 69164-01. At this time, all parcels are vacant.
Pursuant to Section 66474.1 of the Subdivision Map Act, a legislative body shall not deny
approval of a final or parcel map if it was previously approved as a tentative map for the
proposed subdivision and if it finds the final or parcel map is in substantial compliance with the
previously approved tentative map.
The Final Tract Map was reviewed to the satisfaction of the City Engineer and found to be in
substantial conformance with the previously approved tentative tract map. The conditions of
approval established by the City were also met and fees have been and/or will be paid as
indicated on the attached Fact Sheet. Bridge and Thoroughfare fees are required to be paid prior
to issuance of building permits. Therefore, the Final Tract Map is ready for City Council
approval and acceptance of the dedications.
The project includes a Water Factory that will ultimately be owned and operated by the City with
operation and maintenance costs being paid for by future property owners in Vista Canyon
Ranch. The Water Factory is expected to begin operations in November 2017.
City staff and Vista Canyon Ranch, LLC, have finalized a Water Factory construction
agreement, which is attached hereto, for City Council approval. This construction agreement
details the requirements associated with plan review, bonding, and payment of consulting fees
through this process. A separate agreement will be prepared and presented to the City Council
next year related to operation and turnover of the Water Factory to the City.

ALTERNATIVE ACTION
Staff has not identified alternative actions that would conform to requirements set forth in the
Subdivision Map Act.
FISCAL IMPACT
The public streets shown on the Final Tract Map for Tract No. 69164-01 will be dedicated to the
City of Santa Clarita. The maintenance of these streets will have minimal impact on the City's
street maintenance budget. The developer shall pay Bridge and Thoroughfare, Transit, and
Quimby fees in place prior to issuance of building permits.

WASTE DISCHARGE REQUIREMENTS AND
WATER RECLAMATION REQUIREMENTS
ISSUED TO
CITY OF SANTA CLARITA
(VISTA CANYON WATER FACTORY)
The California Regional Water Quality Control Board, Los Angeles Region (Regional Board)
finds:
INTRODUCTION
The Vista Canyon Project proposes to develop an approximately 185 -acre Vista Canyon
area, providing 1,100 residential units with a residential population estimated at 3,500, as
well as up to 950,000 square feet of commercial and medical offices, retail stores, theater,
restaurants, and hotel. Approximately 932,000 gallons per day (GPD) of wastewater will
be generated from this project, once it is fully developed.
2. The Vista Canyon Water Factory Project (Water Factory Project) proposes to build the
Vista Canyon Water Factory (Water Factory) that is a tertiary wastewater treatment and
recycling plant that treats wastewater generated from the Vista Canyon Project. This
treated wastewater is recycled for on-site and off-site landscape irrigation and other non -
potable applications. During rainy weather, effluent will be conveyed to downstream
facilities of the Santa Clarita Valley Sanitation District (SCVSD), including the Saugus
Water Recycling Plant (WRP) or/and the Valencia WRP. The Saugus WRP will be the
primary plant to treat wastewater. The Valencia WRP is the backup plant to treat the
extra wastewater generated beyond the wastewater treatment capacity of the Saugus
WRP.
The Water Factory construction is anticipated to be completed and begin operation in
October 2017. Once completed, the Water Factory will be operated by the City of Santa
Clarita (City). The City, thereafter defined as Permittee or Discharger, will become the
owner of the Water Factory. The City will be responsible for the treatment of wastewater,
wastewater quality, recycled water quality, and any groundwater quality impacted by the
discharge and the recycled water applications. The City will also be responsible for
compiling and submitting all monitoring data and reports to the Regional Board.
4. The City will distribute recycled water to the City and the Los Angeles County and will
establish appropriate ordinances to (1) regulate the proper uses and distributions of
recycled water, (2) maintain and inspect recycled water facilities, and (3) ban water
softener use.
Adopted June 9, 2016

REGULATORY AGENCIES
Order No. R4-2016-0220
File No. 14-031
5. The Regional Board is the permitting agency for the Water Factory Project for the
discharge of tertiary -treated effluent with disinfection via non -potable recycled water
applications. This Regional Board issues Waste Discharge Requirements (WDRs) and
Water Reclamation Requirements (WRRs) to assure that this Project does not adversely
affect the receiving groundwater quality and its beneficial uses.
6. The Regional Board is required pursuant to California Water Code section 13523 to
consult with and receive recommendations from the Division of Drinking Water (DDW)
within the State Water Resources Control Board (State Water Board) (formerly within the
California Department of Public Health) regarding public health, safety, or welfare.
PURPOSE OF ORDER
7. Pursuant to California Water Code (CWC) sections 13260 (WDRs) and 13522.5 (WRRs),
the City submitted a Report of Waste Discharge (ROWD) on March 20, 2014 and applied
for WDRs and WRRs to discharge disinfected tertiary -treated wastewater generated at the
Water Factory for non -potable recycled water applications.
8. CWC section 13260 requires any person "proposing to discharge waste, within any region
that could affect the quality of the waters of the state, other than to a community sewer
system," to file a report of waste discharge. The term "waste" is defined in CWC section
13050(d) to include "sewage and any and all other waste substances, liquid, solid,
gaseous, or radioactive, associated with human habitation, or of human or animal origin, . .
. prior to, and for purposes of, disposal." The Discharger proposes to discharge human
sewage, i.e., "waste" to land where it could affect the quality of the waters of the state.
Sewage contains various waste constituents, including total dissolved solids, sulfate, salts
(e.g., chloride, boron), bacteria, nitrogen, priority pollutants and constituents of emerging
concern (CECs). In accordance with CWC section 13263(g), no discharge of waste into
waters of the state, whether or not the discharge is made pursuant to waste discharge
requirements, shall create a vested right to continue the discharge. All discharges of
waste into waters of the state are privileges, not rights.
9. CWC section 13263 authorizes the Regional Board, after any necessary hearing, to
prescribe requirements as to the nature of any proposed discharge with relation to the
conditions existing in the disposal area or receiving waters upon, or into which, the
discharge is made or proposed. The requirements must implement any relevant water
quality control plans that have been adopted, and shall take into consideration the
beneficial uses to be protected, the water quality objectives reasonably required for that
purpose, other waste discharges, the need to prevent nuisance, and the provisions of
CWC section 13241.
10. CWC section 13267 authorizes the Regional Board to require that any person who
proposes to discharge waste to furnish, under penalty of perjury, technical or monitoring
program reports which the regional board requires. The burden, including costs, of these
reports shall bear a reasonable relationship to the need for the report and the benefits to
be obtained from the reports. In requiring those reports, the regional board shall provide
the person with a written explanation with regard to the need for the reports, and shall
identify the evidence that supports requiring that person to provide the reports. This Order
incorporates Monitoring and Reporting Program (MRP) Cl. No. 10041 for the City (File No.
4
City of Santa Clarlta
Vista Canyon Water Factory
Order No. R4-2016-0220
File No. 14031
14-031), which
is necessary to assure that the
discharge of
waste, including the use of
recycled water
complies with this Order and
is protective
of human health and the
environment.
11. This Order is adopted pursuant to CWC sections 13263, 13267, and 13523. It sets forth
requirements, prohibitions, and other conditions to implement the Basin Plan; prescribes
the limits for the recycled water and the Discharger's responsibilities for the production,
distribution, monitoring, and application of recycled water; and includes an MRP. The
Discharger is responsible for inspecting point -of -use facilities, and ensuring compliance
with the WDRs and WRRs contained in this Order.
12. For the purposes of this Order, references to the "discharger" or "permittee" in applicable
federal and state laws, regulations, plans, or policy are held to be equivalent to references
to the City.
13. A Water Factory Project site visit was conducted on August 10, 2015. The site is along the
Santa Clara River with an estimated distance of 500 feet southeast to the center of the
Santa Clara River. The majority of the riverbed adjacent to the site is dry with no surface
water observed as this is a dry reach of the Santa Clara River during dry weather.
Currently, the site is under grading for development.
VISTA CANYON PROJECT
14. Vista Canyon Project Vicinity
A. The Vista Canyon Project (Figure 1) is located in the Santa Clarita Valley in the
unincorporated Los Angeles County, directly adjacent to the City. The Vista Canyon
Project is immediately south of State Route 14 (SR -14), west of La Veda Avenue,
north of the Metrolink rail line, and east of the Colony Townhome community. The
Vista Canyon Project is also in Management Zone 1 of the Salt and Nutrient
Management Plan Santa Clara River Valley East Subbasin.
B. The Vista Canyon Project is in the eastern portion of the easternmost Subbasin of
the Santa Clara River, known as the Eastern Santa Clara Groundwater Basins (DWR
Basin No. 4-4.07) (Figure 2) defined in the Basin Plan, specifically within the Santa
Clara -Mint Canyon area.
15. Water Factory
A. The proposed Water Factory (340 24' 51.73" N, 1180 26' 22.58" W) will be located in
the southwest corner of the Vista Canyon Project and approximately 200 feet from
Santa Clara River (Figure 1).
B. Wastewater generated from the Vista Canyon Project will be conveyed by gravity
flow to the Water Factory.
C. The Water Factory has a design capacity of 392,000 gallons per day (GPD), which
will generate 371,000 GPD of effluent to be recycled. The wastewater treatment
process (See Figure 3 for process flow schematic) consists of preliminary treatment
(comminutor), flow equalization (flow equalization basin), secondary treatment with
a retention time of 18 hours (two aeration tanks with nitrification and denitrification

Order No. R4-2016-0220
File No. 14.031
activated sludge, reducing ammonia and nitrate concentrations), clarification with a
retention time of 0.5 hour (two sedimentation tanks with coagulation and
flocculation, reducing solids), tertiary treatment (disc filters, reducing turbidity, and
suspended solids greater than 85%), and disinfection (UV and chlorination with
sodium hypochlorite). The sludge (21,000 GPD), any excess treated effluent not
being recycled from the Water Factory, and any untreated wastewater generated
from the Vista Canyon Project will be discharged to the downstream facilities of the
SCVSD, including the Saugus Water Recycling Plant (WRP) or/and the Valencia
WRP. Any effluent not meeting effluent limitations will be delivered to the
headworks for further treatment.
D. Influent Quality
The Santa Clarita Water Division (SCWD) is the primary water district which
supplies potable water to the Vista Canyon Project and is one of four water
retailers (Santa Clarita Water Division, Newhall County Water District, Valencia
Water Company, and Los Angeles County Waterworks District No. 36)
supplying potable water to communities in the Santa Clarita Valley. The SCWD
blends imported water purchased from the Castaic Lake Water Agency
(CLWA) with local groundwater. Based on the records provided by SCWD for
the period of 2001 through 2014, the percentage of use of imported water
from CLWA ranged from 55.7% to 84.7%. In the years between 2011 and
2014, which are considered as drought years, the use of imported water has
increased from 60.5 % (2011) to 84.7% (2014).
Based on water quality data collected between year 2010 and 2014, the
imported water purchased from CLWA has better water quality (see column 2
of Table 1 below), on average, than the local groundwater (Column 3 of Table
1). The water supply records (2001-2014) indicate that the percentage of
imported water for drinking water has never been below 55%. The average
imported water used during drought years of 2010 through 2014 was 68.6%.
The blending of 50% groundwater with 50% imported water takes into
account the range of water supply quality during drought years based on the
historical blending records. Column 4 of Table 1 is the anticipated potable
water quality, resulting from the blending 50% of imported water with another
50% of local groundwater.
C. The estimated influent quality of the Water Factory (Column 6 of Table 1)
results from the summation of Column 4 (anticipated potable water quality)
and Column 5 in Table 1. Column 5 in Table 1 is the addition of concentration
as the result of contributions of pollutants from household use.

d. The City Plumbing Code adopted on November 26, 2013 and the SCVSD
Ordinance adopted on June 11, 2008 prohibits water softener installation within
the site boundary. The purpose of the Code and the Ordinance is to limit the
discharge of total dissolved solids including chloride to the Water Factory,
which is not designed to remove salts.
E. Effluent Quality
The Water Factory is a new facility and not designed to remove salts through its
wastewater treatment process, therefore, the salt concentrations in the effluent will
be the same as those in the influent (Table 1), however, compliance with effluent
limits must be achieved. Based on the proposed tertiary treatment process, the
nutrients in effluent, under proper operation and maintenance, will achieve the
effluent limits in Table 2 below.

F. Treated Effluent Applications
a. The treated effluent will be stored in a 100,000 -gallon recycled water storage
tank. Recycled water will be distributed via the recycled water pump station to
on-site uses of the Vista Canyon Project for landscape irrigation and public
restrooms in commercial areas and off-site uses for landscape irrigation and
other Title 22 non -potable recycled water applications approved by the DDW. A
summary of proposed recycled water uses are shown in Table 3. Figure 4
presents the quantity of recycled water uses at each location.

G. Effluent Storage Equalization Tank
A 200,000 -gallon effluent storage equalization tank (Figure 5) will be
constructed adjacent to the Water Factory and along the Santa Clara River
bank in order to store the treated wastewater with the following conditions:
Disinfected tertiary -treated effluent when there is no demand for recycled
water; and,
ii. Overflow from the 100,000 -gallon recycled water storage tank.
Water in excess of this capacity will be sent downstream to either the Saugus
or Valencia recycling facilities.
b. The Water Factory and the bank along the Santa Clara River are within the
100 -year floodplain and will be raised in elevation and will no longer be within
the floodplain. The bank along the Santa Clara River is reinforced and
protected by a concrete retaining wall (approximately 18 feet) plus a freeboard
(approximately 3 feet) above the Santa Clara River corridor. This wall is

designed in conformance with the County of Los Angeles Capital -Flood (Qcap)
requirements, which exceed a 1,000 -year storm event.
GROUNDWATER MONITORING PROGRAM
16. Groundwater monitoring wells, specified in Figure 6, are used to ensure that the treated
effluent (recycled water) used for landscape irrigation does not cause the groundwater to
exceed groundwater limits set forth in Table 9 in the Vista Canyon Project site.
17. The groundwater network monitoring program implemented by the City consists of a total
of nine (9) wells, six (6) upgradient; two (2) downgradient, and one (1) cross -gradient.
More information of these groundwater monitoring wells is available in Table 4, Section IV.
3.A. of the accompanying Monitoring and Reporting Program Cl No. 10041 (MRP).
GLOBAL WARMING AND CLIMATE CHANGE
18. In Southern California, the predicted impacts of climate change are numerous. Annual
average temperatures are expected to increase, coupled with a higher frequency of
extreme heat days. A likely consequence of this warmer climate will be more severe
drought periods, leading to an increase in the amount and intensity of fires and a longer
fire season. In addition, precipitation patterns are likely to be modified. A decrease in
snowfall, combined with warmer temperatures, will induce a decrease in the amount and
duration of snowpack, an essential source of freshwater to the region. Although changes
to mean precipitation are expected to be small, the increasing occurrence of extreme
precipitation events will amplify the risk of flooding.
These impacts may affect water quality in multiple ways, including decreases in stream
flow, reductions in, and changes to, aquatic habitats, increases in surface water
temperature, increases in pollutant levels, sedimentation, algal growth, and changes in
salinity levels and acidification in coastal areas. For permitted facilities such as Publicly
Owned Treatment Works (POTWs), specific impacts could include, but are not limited to,
an increase in the concentration of pollutants entering the facility, an increase in the
temperature of effluents and receiving waters, an increase in storm water inflow and
infiltration, increase in flooding/inundation of facilities, sewer overflows, power outages,
pump maintenance issues, and onsite or nearby hillside destabilization.
Executive Order B-30-15, issued on April 29, 2015, recognizing the challenges posed by
climate change, directed state agencies to take climate change into account in their
planning decisions, guided by the following principles: Priority should be given to actions
that both build climate preparedness and reduce greenhouse gas emissions; where
possible, flexible and adaptive approaches should be taken to prepare for uncertain
climate impacts; actions should protect the state's most vulnerable populations; and
natural infrastructure solutions should be prioritized.
19. The Water Factory and the bank along the Santa Clara River are within the 100 -year
floodplain. Therefore, in response to anticipated climate change effects, the City has
considered additional flood control measures and protection of the Vista Canyon Project
and the Water Factory Project, including the design of a concrete retaining wall along the
Santa Clara River bank exceeding protections from impacts from a 1,000 -year storm event
City of Santa Clarita
Vista Canyon Water Factory
Order No. R4.2016-0220
File No. 14.031
(see Finding No. 15.G.b. for more information). Climate change may also increase drought
and related impacts such as reduced potable water supply. The Water Factory will
produce a new source of recycled water for areas of Los Angeles County and the City to
reduce the need for potable water use in the area.
20. Waste Discharge Requirements for this facility contain provisions to require planning and
actions to address climate -related impacts that can cause or contribute to violations of
permit requirements and/or degradation of waters of the state.
APPLICABLE PLANS, POLICIES AND REGULATIONS
Due to the unique hydrogeological conditions of the Plant location and its vicinity, this permit
incorporates Basin Plan, Title 22 CCR, and other essential plans, policies, and regulations to
protect the receiving groundwater quality.
21. Water Quality Control Plan for the Coastal Watersheds of Los Angeles and Ventura
Counties (Basin Plan) — On June 13, 1994, the Regional Board adopted a revised Basin
Plan. The Basin Plan (i) designates beneficial uses for surface and groundwater, (ii)
establishes narrative and numeric water quality objectives that must be attained or
maintained to protect the designated beneficial uses, and (iii) sets forth implementation
programs to protect the beneficial uses of the waters of the state. The Basin Plan contains
prohibitions on the discharge of certain types of waste or to specified locations. The Basin
Plan also incorporates State Water Board Resolution 68-16 "Statement of Policy with
Respect to Maintaining High Quality of Waters in California" (also called the
"Antidegradation Policy"). In addition, the Basin Plan incorporates by reference applicable
State and Regional Board plans and policies and other pertinent water quality policies and
regulations. The Regional Board prepared the 1994 update of the Basin Plan to be
consistent with previously adopted State and Regional Board plans and policies. This Order
implements the plans, policies and provisions of the Regional Board's Basin Plan. The Basin
Plan has been amended occasionally since 1994.
The Basin Plan (Chapter 3) incorporates Title 22 CCR primary maximum contaminant
levels (MCLS) by reference (see Finding No. 20 below for detail) as water quality objectives.
This incorporation by reference is prospective including future changes to the incorporated
provisions as the changes take effect. The Title 22 CCR primary MCLs are applicable
water quality objectives for a receiving water to protect beneficial uses when that receiving
water is designated as municipal and domestic supply. Also, the Basin Plan specifies that
"Ground waters shall not contain taste or odor -producing substances in concentrations
that cause nuisance or adversely affect beneficial uses." Therefore the Title 22 CCR
secondary MCLs, which are limits based on aesthetic, organoleptic standards, are
applicable water quality objectives for a receiving water to protect beneficial uses when
that receiving water is designated as municipal and domestic supply. These water quality
objectives are implemented in this Order to protect groundwater quality.
In addition, the Basin Plan implements State Water Board Resolution No. 88-63, which
established state policy that all waters, with certain exceptions, should be considered
suitable or potentially suitable for municipal or domestic supply. Beneficial uses applicable
to the groundwater in Table 5 are as follows:

A. Total Maximum Daily Loads (TMDLs). To restore water quality and impaired
beneficial uses, the Regional Board has adopted the Nitrogen Compounds TMDLs
for the Santa Clara River Reach 7 (Figure 7). The TMDLs has assigned local
allocation for nonpoint source contributions from agricultural and urban runoff and
groundwater discharge (Table 6):

the Regional Board on August 7, 2003, the State Water Board on November 19, 2003,
the Office of Administrative Law on February, 27, 2004, and the USEPA on March 18,
2004.
The treated effluent for irrigation percolating from the Site will reach underlying
groundwater, which are likely to connect to the Santa Clara River Reach 7.
Resolution No. 2003-011 has assigned a load allocation for nutrients to groundwater.
However, considering the soil composition, groundwater depth, and quality of effluent
discharged, the more stringent nutrient effluent limit (see section 11.2.) shall be
imposed to ensure the protection of groundwater quality based on the
Antidegradation analysis.
B. Clean Water Act section 401 Water Quality Certification. On April 24, 2013, the
Regional Board issued an order (File No. 12-034, see Attachment A for more
information including the Water Quality Certification, Project Information, and
Conditions of Certification) certifying that any discharge from the Vista Canyon
Project including Water Factory Project would comply with the applicable provisions
of Clean Water Act section 301 (Effluent Limitations), section 302 (Water Quality
Related Effluent Limitations), section 303 (Water Quality Standards and
Implementation Plans), section 306 (National Standards of Performance), and
section 307 (Toxic and Pretreatment Effluent Standards) of the Clean Water Act, and
with other applicable requirements of State law. This discharge is also regulated
under State Board Order No. 2003-0017-DWQ, "General Waste Discharge
Requirements for Dredge and Fill Discharges that have received State Water Quality
Certification" which requires compliance with all conditions of this Water Quality
Certification.

22. Title 22 CCR —Title 22 CCR contains primary and secondary MCLs for inorganic, organic,
and radioactive contaminants in drinking water. These MCLs are codified in Title 22 CCR.
Title 22 primary MCLs (see Attachments B-1 to B-6) have been incorporated into the Basin
Plan as water quality objectives. MCLs are used as one of the primary bases for effluent
limits for discharges of recycled water in WDRs and WRRs to protect the designated
beneficial uses of municipal and domestic supply.
23. Recycled Water Policy — State Water Board Resolution No. 2009-0011, Adoption of a
Policy for Water Quality Control for Recycled Water (Recycled Water Policy), is intended
to support the State Water Board's Strategic Plan to promote sustainable local water
supplies. Increasing the acceptance and promoting the use of recycled water is a means
towards achieving sustainable local water supplies and can result in reduction in
greenhouse gases, a significant driver of climate change. The Recycled Water Policy is
also intended to encourage beneficial use of, rather than solely disposal of, recycled water
generated from municipal wastewater sources in a manner that fully implements state and
federal water quality laws.
24. State Water Board Resolution No. 68-16 Antidegradation requires the Regional Board, in
regulating the discharge of waste, to maintain the high quality waters of the state until it is
demonstrated that any change in quality will be consistent with maximum benefit to the
people of the State, will not unreasonably affect beneficial uses, and will not result in water
quality less than that described in the State Water Board's policies (e.g., quality that
exceeds water quality objectives). Further, any activity that produces waste must meet
waste discharge requirements that will result in the best practicable treatment or control of
the discharge necessary to assure that (a) a pollution or nuisance will not occur and (b) the
highest water quality consistent with maximum benefit to the people of the State will be
maintained.
In accordance with the Recycled Water Policy, the Upper Santa Clara River Integrated
Regional Water Management Group, which is comprised of CLWA, City, Santa Clarita
Water Division, Los Angeles County Flood Control District, Newhall County Water District,
San Gabriel & Lower Los Angeles Rivers and Mountains Conservancy, SCVSD, and
Valencia Water Company entered into a Memorandum of Understanding to prepare the
draft Salt and Nutrient Management Plan Santa Clara River Valley East Subbasin (SNMP
East Subbasin). This group of agencies collectively known as the Salt and Nutrient Task
Force facilitated by the CLWA directed the preparation of the SNMP East Subbasin,
which was prepared using guidance set forth by the Regional Board.
The draft SNMP East Subbasin provides a conceptual analysis on the possible
groundwater quality impacts resulting from the discharge. Staff conducted an independent
antidegradation analysis taking into consideration work done under the SNMP effort and
analyzed the data using a mass balance. The use of recycled water generated from the
Water Factory will not cause degradation of the receiving groundwater quality for TDS,
chloride, nitrate, and sulfate. The concentrations of chloride, nitrate, and sulfate in
groundwater will remain the same as the current concentrations.

25. This Order establishes effluent and groundwater limitations that will prevent unreasonable
threats to present and anticipated beneficial uses and will not result in receiving ground
water quality that exceeds water quality objectives set forth in the Basin Plan. Limitations
for each waste constituent are based on the most stringent applicable water quality
objective to protect all beneficial uses. This Order contains requirements for assuring that
BPTC and the highest water quality consistent with the maximum benefit to the people of
the State will be achieved. Accordingly, the discharge is consistent with the
antidegradation provisions of Resolution 68-16. Based on the results of wastewater
treatment and monitoring of effluent and groundwater quality, the Regional Board may
reopen this Order to reconsider groundwater limitations and other requirements to comply
with Resolution 68-16.
26. AB 685 - CWC Section 106 - It is the policy of the State of California that every human
being has the right to safe, clean, affordable, and accessible water adequate for human
consumption, cooking, and sanitary purposes. This Order promotes that policy by requiring
discharges to meet maximum contaminant levels developed to protect human health and
ensure that water is safe for domestic use.
27. This Order is established pursuant to CWC section 13263 because this project has the
potential to affect the quality of the waters of the State, to impact the beneficial uses of
those waters, or to cause a nuisance. This Order conforms to CWC section 13523 and
State Water Board Resolution 2009-011, the Recycled Water Policy, because it meets the
need for recycled water use.
28. Section 13523 of the CWC provides that a Regional Board, after consulting with and
receiving recommendations from DDW or its delegated local health agency, and after any
necessary hearing, shall, if it determines such action to be necessary to protect the health,
safety, or welfare of the public, prescribe water recycling requirements for water that is
used or proposed to be used as recycled water. Section 13523 further provides at a
minimum that the recycling requirements shall include, or be in conformance with, the
statewide water recycling criteria established by DDW pursuant to Water Code Section
13521. DDW adopted revised Water Recycling Criteria (Chapter 3, Division 4, Title 22,
CCR) that became effective on June 18, 2014. Criteria applicable to this recycling project
are prescribed in this Order.
29. These WRRs are established pursuant to CWC section 13523. The WRRs prescribe the
limits for recycled water and the City's responsibilities for the production and monitoring of
recycled water and ensuring compliance with the WRRs contained in this Order.

Order No. R4.2016-0220
File No. 14.031
30. The City prepared the revised Engineering Report for the Vista Canyon Water Factory
(Municipal Wastewater Treatment Facility), dated November 16, 2015, on its proposed
production, distribution, and use of recycled water for irrigation as required by section
60323 of Title 22, CCR. On December 1, 2015, the revised Title 22 Engineering Report
was conditionally approved by the DDW with recommendations to the Regional Board.
This Order incorporates conditions and requirements in the Attachment A, consistent with
DDW's recommendations.
31. State Water Board Resolution No. 77-1— The State Water Board adopted Resolution No.
77-1, Policy with Respect to Water Recycling in California, which includes principles that
encourage and recommend funding for water recycling and its use in water -short areas of
the State. On September 26, 1988, the Regional Board also adopted Resolution No. 88-
012, Supporting Beneficial Use of Available Reclaimed Water in Lieu of Potable Water for
the Same Purpose, which encourages the beneficial use of recycled wastewater and
supports water recycling projects.
32. The requirements contained in this Order are in conformance with the goals and objectives
of the Basin Plan, the TMDLs, and implement the requirements of the CWC, Title 22,
Recycled Water Policy, and Resolutions specified in this Order.
33. Publicly Owned Treatment Works (POTW) — The term POTW means a treatment works
as defined by section 212 of the federal Clean Water Act, which is owned by a State or
municipality (as defined by section 502(4) of the Act). This definition includes any devices
and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes sewers, pipes and other
conveyances only if they convey wastewater to a POTW treatment facility. The term also
means the municipality as defined in section 502(4) of the Clean Water Act, which has
jurisdiction over the indirect discharges to and the discharges from such treatment works.
(40 CFR 403.3(q)). The Water Factory meets all above criteria and therefore is considered a
POTW.
34. Constituents of Emerging Concerns (CEC) Requirements - In recent years, the Regional
Board has incorporated monitoring of a select group of anthropogenic chemicals,
particularly pesticides, pharmaceuticals and personal care products, known collectively as
CECs, into permits to better understand the propensity, persistence and effects of CECs in
our environment. Recently adopted permits in this region contain requirements for CEC
effluent monitoring, including identification of the CECs to be monitored in the effluent,
sample type, sampling frequency, and sampling methodology.
CEQA AND NOTIFICATION
35. The City is the lead agency for purposes of the California Environmental Quality Act
(CEQA) (Pub. Res. Code §§21000 et seq). The City released a Notice of Preparation
(NOP) on October 1, 2009. The NOP provided notice to the public and public agencies
that an Environmental Impact Report (EIR) would be prepared for the construction of the
Vista Canyon Project. The Draft EIR was released for public comment on October 19,
2010, with notices published in the Signal Newspaper, notices mailed to interested parties,
and notices mailed to the State Clearinghouse for circulation to responsible agencies
(SCH No. 2007071039). The comment was due on December 3, 2010. Thirty-one written
and oral comments were received, including a comment letter from the Regional Board
dated December 2, 2010. The City conducted Planning Commission Meetings on October

Order No. 114-2016-0220
File No. 14.031
19, 2010, November 2, 2010, and December 21, 2010 and a City Council Hearing on
March 22, 2011 to accept verbal comments on the Draft EIR. On April 26, 2011, the City
Council held a public hearing and certified the Final EIR.
The EIR had identified the potential impacts on wastewater disposal and water quality,
resulting from the development of the Vista Canyon Project. To mitigate the impacts to
groundwater and surface water quality caused by wastewater disposal, the Water Factory
Project, pursuant to local, regional, state and federal design standards, proposed to treat
the domestic wastewater to the Title 22 Recycled Water standards at the Water Factory
and will not cause any adverse impact to the underlying groundwater aquifer. The
discharge is also required to obtain all necessary permits for the construction of the Vista
Canyon Project and the Water Factory Project.
36. The Regional Board is a responsible agency for purposes of CEQA and has considered
the EIR prepared by the City. The Regional Board has incorporated requirements into this
Order to protect the quality of the waters of the state consistent with the applicable plans
and policies that apply to the discharges regulated by this Order. This Order is consistent
with the mitigation measures identified by the City in the EIR because it requires
compliance with Title 22 standards. This Order includes a monitoring and reporting
program to determine compliance with the terms of the Order, including the Title 22
standards, and to assure protection of water quality.
37. Petition — Any person aggrieved by this action of the Regional Board may petition the
State Water Board to review the action in accordance with CWC section 13320 and CCR
title 23, sections 2050 and following. The State Water Board must receive the petition by
5:00 p.m., 30 days after the date of this Order, except that if the thirtieth day following the
date of this Order falls on a Saturday, Sunday, or a state holiday, the petition must be
received by the State Water Board by 5:00 pm on the next business day. Copies of the law
and regulations applicable to filling petitions may be found on the Internet at
http://www.waterboards.ca.gov/public notices/petitions/water quality/ or will be provided
upon request.
38. Public Notice — On April 20, 2016, the Regional Board notified the City and interested
agencies and persons of its intent to issue WDRs/WRRs Order No. R4-2016-0220 for the
distribution and use of tertiary -treated and disinfected effluent as recycled water, and has
provided them with an opportunity to submit written comments.
The Regional Board, in a public meeting, heard and considered all comments pertaining to
these WDRS/WRRs.

facility) is prohibited. The Regional Board may take enforcement action against the
City for bypass unless:
A. Bypass was unavoidable to prevent loss of life, personal injury, or severe
property damage. (Severe property damage means substantial physical damage
to property, damage to the treatment facilities that cause them to become
inoperable, or substantial and permanent loss in the absence of a bypass.
Severe property damage does not mean economic loss caused by delays in
production.)
B. There were no feasible alternatives to bypass, such as the use of auxiliary
treatment facilities, retention of untreated waste, or maintenance during normal
periods of equipment down time. This condition is not satisfied if adequate back-
up equipment shall have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that could occur during normal periods of
equipment downtime or preventive maintenance.
C. The City must submit written notice at least 24 hours in advance of the need for
a bypass to the Regional Board Executive Officer.
11. Any discharge of wastewater from the treatment system (including the wastewater
collection system) at any point other than specifically described in this Order and
except as provided for in Section V111.10 of this Order, is prohibited and constitutes a
violation of this Order.
12. Any discharge of effluent/recycled water at any point(s) other than designated
recycled water use areas is prohibited and constitutes a violation of this Order.
13. The discharge of effluent, including runoff, spray or droplets from the irrigation
system, shall not occur outside the boundaries of the land application area.
14. The discharge of waste to surface waters of the state or of the United States is
prohibited.

Order No. R4-2016-0220
File No. 14-031
The City shall submit plans for any change of the recycled water project to and
obtain approval from DDW and the Regional Board. The American Water Works
Association Guidelines for the Distribution of Non -Potable Water shall be followed,
including installation of purple pipe, adequate signs, etc. As -built drawings shall
show the final locations of the potable water, sewer, and recycled water pipelines;
and indicate adequate separation between the recycled water and potable domestic
water lines, which shall also be marked clearly or labeled using separate colors for
identification. In addition, a copy of each application to DDW for a recycled water
project shall be delivered to the Regional Board for inclusion in the administrative file.
2. If the recycled water system lateral pipelines are located on an easement contiguous
to a homeowners private property and where there is a reasonable probability that an
illegal or accidental connection to the recycled water line could be made, the City or
its authorized agency shall provide a buffer zone or other necessary measures
between the recycled water lines and the easement to prevent any illegal or
accidental connection to the recycled water lines. If the City or its authorized agency
does not feel it can maintain adequate control of the recycled water system pipelines,
the pipelines will need to be relocated or a physical barrier needs to be installed to
prevent this type of potential problem. The homeowners need to be educated on the
use of recycled water in the area. The City or its authorized agency should specify a
plan to interface with the homeowners as a part of the Rules of Service Agreement in
an adjacent property awareness program.
3. The City or its authorized agency shall inspect the recycled water use areas on a
periodic basis. A report of findings of the inspection shall be submitted to the City
that will incorporate it with the quarterly report, specified in the MRP, to the DDW and
the Regional Board.
4. The City shall file with the Regional Board, under penalty of perjury, annual and
quarterly reports on self-monitoring work performed according to the detailed
specifications contained in MRP attached hereto and incorporated herein by reference,
as directed by the Executive Officer. The results of any monitoring done more
frequently than required at the location and/or times specified in the MRP shall be
reported to the Regional Board. The Discharger shall comply with all of the provisions
and requirements of the MRP.
5. The City shall notify DDW and this Regional Board by telephone or electronic means
within 24 hours of knowledge of any violations of recycled water use conditions, any
adverse conditions as a result of the use of recycled water and any discharge
exceeding the effluent limits prescribed in this Order from the Water Factory or/and
the recycled water storage basin; written confirmation shall follow within 5 working
days from date of notification, unless otherwise specified in this Order. The report
shall include, but not limited to, the following information, as appropriate:
A. Nature and extent of the violation;
B. Date
and
time: when
the violation started, when
compliance was achieved;
and,
when
discharge was suspended and restored,
as applicable;
23
City of Santa Clarita Order No. R4-2016-0220
Vista Canyon Water Factory File No. 14-031
C. Duration of violation;
D. Cause(s) of violation;
E. Corrective and/or remedial actions taken and/or will be taken with time
schedule for implementation to prevent future violations; and
F. Impact of the violation.
6. The direct use of disinfected recycled water for irrigation and unpaved roadway dust
control could affect the public health, safety, or welfare; requirements for such uses
are therefore necessary in accordance with Section 13523 of the Water Code.
7. This Order does not exempt the City and its authorized agencies from compliance
with any other laws, regulations, or ordinances which may be applicable; they do not
legalize the recycling and use facilities; and they leave unaffected any further
constraint on the use of recycled water at certain site(s) that may be contained in
other statutes or required by other agencies.
8. This Order does not alleviate the responsibility of the City and its authorized
agencies to obtain other necessary local, state, and federal permits to construct
facilities necessary for compliance with this Order; nor does this Order prevent
imposition of additional standards, requirements, or conditions by any other
regulatory agency. Expansion of the recycled water distribution facility shall be
contingent upon issuance of all necessary requirements and permits, including a
conditional use permit.
9. After notice and opportunity for a hearing, this Order may be modified, revoked and
reissued, or terminated for cause, that include, but is not limited to: failure to comply
with any condition in this Order, endangerment of human health or environment
resulting from the permitted activities in this Order, obtaining this Order by
misrepresentation or failure to disclose all relevant facts, and acquisition of new
information which could have justified the application of different conditions if known
at the time of Order adoption.
The filing of a request by the City for modification, revocation and reissuance, or
termination of the Order; or a notification of planned changes or anticipated
noncompliance does not stay any condition of this Order.
10. The City shall furnish, within a reasonable time, any information that the Regional
Board may request to determine whether cause exists for modifying, revoking and
reissuing, or terminating this Order. The City shall also furnish the Regional Board,
upon request, with copies of records required to be kept under this Order for at least
three years.
11. In an enforcement action, it shall not be a defense for the City that it would have
been necessary to halt or to reduce the permitted activity in order to maintain
compliance with this Order. Upon reduction, loss, or failure of the treatment facility,
the City shall, to the extent necessary to maintain compliance with this Order, control
production or all discharges, or both, until the facility is restored or an alternative

there is any conflict among provisions stated in the MRP and these WDRs/WRRs,
those provisions stated herein before prevail.
14. After a year of percolating recycled water into the aquifers, the City shall update the
operation, maintenance, and monitoring plan (OMM Plan) and submit it to the
Regional Board for review and approval, if there is any change to the original OMM
Plan. The Water Factory shall be operated in accordance with the approved plan.
The OMM Plan shall cover critical operational parameters to include routine testing
procedures for optimization of the UV dose for disinfection and reduction of light-
sensitive contaminants, and all treatment processes, maintenance and calibration
schedules for all monitoring equipment, process alarm set points, and response
procedures for all alarms in each treatment process of the Water Factory, including
criteria for diverting recycled water if water quality requirements are not met, start-up,
emergency response and contingency plans. During the first year of operation of the
Water Factory, all treatment processes shall be optimized to reduce contaminant
levels. The results of these Initial optimization efforts shall be incorporated into the
updated OMM Plan. The OMM Plan shall include staffing levels with applicable
certification levels for the Water Factory operations personnel. Significant changes
in the operation of any of the treatment processes shall be reported to the DDW and
the Regional Board. Changes in the approved OMM Plan must be approved by the
DDW and the Regional Board prior to instituting changes.
15. For any material change or proposed change in character, location or volume of
recycled water, or its uses, the City shall submit at least 120 days prior to the
proposed change an engineering report or addendum to the existing engineering
report to the Regional Board and DDW [pursuant to CWC, sections 13260(c) and
13522 and CCR, Title 22, Section 60320.080] for approval.
16. The City shall provide an Annual Report described in the MRP to this Regional

E. Analytical test methods used and the corresponding Detection Limits for
Purposes of Reporting (DLR) for unregulated and regulated chemicals. Please
see the DDW's website at
http://www.waterboards.ca.gov/drinking water/certlic/drinkingwater/EDT.shtml
for unregulated and regulated chemicals.
F. Quality assurance and control measures.
2. Unless specified differently below, all samples shall be analyzed using analytical
methods described in 40 CFR Part 136; or where no methods are specified for a
given pollutant, by commercially available methods approved by the United State
Environmental Protection Agency (USEPA) or DDW, Regional Board and/or State
Water Board. The City shall select the analytical methods that provide reporting
detection limits (RDLs) lower than the limits prescribed in the accompanying Order
No. R4-2016-0220.
3. The City shall instruct its laboratories to establish calibration standards so that the
RDLs (or its equivalent if there is a different treatment of samples relative to
calibration standards) are the lowest calibration standard. At no time shall the City
use analytical data derived from extrapolation beyond the lowest point of the
calibration curve.
4. Upon request by the City, the Regional Board, in consultation with the USEPA or
DDW and the State Board Quality Assurance Program, may establish RDLs, in any
of the following situations:
A. When the pollutant has no established method under 40 CFR 136 (revised
May14, 1999, or subsequent revision);
B. When the method under 40 CFR 136 for the pollutant has a RDL higher than
the limit specified in this Order; or,
C. When the City agrees to use a test method that is more sensitive than those
specified in 40 CFR Part 136 and is commercially available.
5. Samples of influent and disinfected effluent must be analyzed within allowable
holding time limits as specified in 40 CFR Part 136.3. All QA/QC analyses must be
run on the same dates when samples were actually analyzed. The City shall make
available for inspection and/or submit the QA/QC documentation upon request by
Regional Board staff. Proper chain of custody procedures must be followed and a
copy of that documentation shall be submitted with the quarterly report.
6. For unregulated chemical analyses, the City shall select methods according to the
following approach:
A. Use drinking water methods, if available;
B. Use DDW-recommended methods for unregulated chemicals, if available;
T-3
City of Santa Clarita
Vista Canyon Water Factory
Monitoring and Reporting Program No. Cl 10041
File No. 14-031
C. If there is no DDW-recommended drinking water method for a chemical, and
more than a single USEPA-approved method is available, use the most
sensitive USEPA-approved method;
D. If there is no USEPA-approved method for a chemical, and more than one
method is available from the scientific literature and commercial laboratory,
after consultation with DDW, use the most sensitive method;
E. If no approved method is available for a specific chemical, the City's laboratory
may develop or use its own methods and should provide the analytical
methods to DDW or the Regional Board for review. Those methods may be
used until DDW recommended or USEPA-approved methods are available.
F. If the only method available for a chemical is for wastewater analysis (e.g., a
chemical listed as a priority pollutant only), sample and analyze for that
chemical in the treated and disinfected effluent. Use this approach until the
City's laboratory develops a method for the chemical in drinking water, or until
a DDW-recommended or USEPA-approved drinking water method is available.
G. The City is required to inform the Regional Board, in event that D, E, F is
occurring.
7. For constituents of emerging concerns (CECs) analyses:
CECs (see Attachment D) are being collected to determine occurrence of these
compounds in the effluent. There are currently no numeric water quality objectives
for the constituents listed in Attachment D. The attached (in Appendix D) reporting
limits shall be used for these constituents.
III. REPORTING REQUIREMENTS
The City shall submit all reports to the Regional Board by the dates indicated in Section I.
All quarterly, and annual monitoring reports shall contain a separate section titled
"Summary of Non -Compliance", which discusses the compliance records and corrective
actions taken or planned that may be needed to bring the reuse into full compliance with
water reclamation requirements. All quarterly and annual reports shall clearly list all non-
