AGENDA REPORT
TO: Honorable City Council

FROM: Sean Corrigan, City Engineer/Public Works Director
Prepared by: Shaun Kroes, Program Manage
DATE:. October 20, 2017 (CC Meeting of 11/01/17)
SUBJECT: Consider Approval of Letter to Los Angeles Regional Water
Quality Control Board Confirming City of Moorpark's Method
to Comply with Statewide Trash Provisions
SUMMARY
The City of Moorpark (City) is required to submit to the Los Angeles Regional Water
Quality Control Board (Regional Board) a letter identifying how it intends to comply with
Statewide Trash Provisions. The letter is due November 20, 2017. Staff is proposing that
the City comply by implementing Track 1 (as identified in the staff report).
BACKGROUND
On August 18, 2017, the City received the attached letter from the Regional Board
regarding Water Code Section 13383 Order to submit method to comply with Statewide
Trash Provisions (Attachment 1). As described in the letter, the State Water Resources
Control Board (Water Board) adopted an Amendment to the Water Quality Control Plan for
Ocean Waters of California on April 7, 2015 (Trash Amendment). The Trash Amendment
establishes a statewide water quality objective for trash for MS4 permittees (such as the
City of Moorpark) that are not already required to comply with a trash Total Maximum Daily
Load.
The City has two options for compliance with the Trash Amendment. The options are:
Track 1: Install, operate, and maintain Full Capture Systems for the storm drain
network that capture runoff from the Priority Land Uses in their
jurisdiction.
226

Track 2: Install, operate, and maintain any combination of Full Capture Systems,
Multi-Benefit Projects, other Treatment Controls, and/or Institutional
Controls within either the jurisdiction of the MS4 permittee or the
jurisdiction of the MS4 permittee and contiguous MS4 permittees.
A Full Capture System is defined as a treatment control, or series of treatment controls,
including but not limited to, a multi-benefit project or a low-impact development control
that traps all particles that are 5 mm or greater, and has a design treatment capacity
that is either: a) of not less than the peak flow rate, Q, resulting from a one-year, one-
hour, storm in the subdrainage area, or b) approximately sized to, and designed to carry
at least the same flows as, the corresponding storm drain. Priority Land Uses are
defined as high density residential (10 units/acre or more), industrial, commercial, mixed
urban, and public_transportation stations. It should be noted that per the Trash
Amendment, selection of Track 2 does not mean that the City would not have to install any
Full Capture Systems. The expectation is that Full Capture Systems would be installed to
the extent that is not cost prohibitive, in addition to establishing additional Multi-Benefit
Projects, other Treatment Controls, and/or Institutional Controls.
DISCUSSION
The City has until November 20, 2017 to submit a letter to the Regional Board stating if the
City will select Track 1 or Track 2 for implementation. After submittal of the letter, the City
then has until February 18, 2019 to submit its implementation plan as detailed on pages 5
and 6 on Attachment 1. Based upon review of the Trash Amendment and discussions
with other MS4 permittees in Ventura County, staff recommends that the City pursue
Track 1. Track 1 has fewer requirements than Track 2, and given that the intent is that Full
Capture Devices would still be required wherever feasible for Track 2, the City may not be
able to significantly reduce the number of Full Capture Devices that would need to be
installed. A draft letter is attached (Attachment 2).
Staff has identified a preliminary estimate of 138 out of 734 catch basins that could require
a Full Capture System based on the City's zoning designation. The number is likely to
increase or decrease as staff evaluates each catch basin and identifies areas where catch
basins may exist where not shown on the City's catch basin map or identifies residential
areas that were actually developed at lower densities than were originally zoned. The City
could identify areas where multiple catch basins drain to a location where it would be more
economical to install one Full Capture System. The City may also be able to work with the
Regional Board to identify an alternative definition of a High Trash Area that would enable
the City to identify fewer catch basins in the City that actually require a Full Capture
System based upon the amount of actual trash identified in the respective catch basins.
227
Honorable City Council
November 1, 2017
Page 3
For example, the City may be able to successfully argue that little trash is generated in
certain industrial zoned areas and that Full Capture Systems are not necessary.
It should be noted that if during the implementation plan time frame the City identifies
catch basins that cannot have a Full Capture System installed for technical reasons, the
City would then have to identify those specific areas where a Track 2 approach would be
taken, and identify how the City will demonstrate Full Capture System Equivalency. These
would be identified as part of the City's February 18, 2019 implementation plan.
Staff also notes that because the Trash Amendment requires Full Capture Systems for
specific land uses, the City would be responsible for any discharges from private storm
drain inlets that connect to the City's storm drain system. For example, if a private storm
drain inlet in a commercial parking lot connects to a City storm drain pipe downstream, the
City would have to identify a location where a Full Capture Device could be installed to
capture that discharge. In some circumstances, the pipe may connect and flow to an open
catch basin where a Full Capture System has or will already be installed. In other
circumstances, the private catch basin may directly discharge to a Caltrans-owned, or
County-owned system. It is staffs' understanding that in those situations the City would
not be required to install any Full Capture Systems. Staff is currently exploring options for
establishing new conditions of approval for new development and redevelopment projects
that would require the installation of Full Capture Systems for private storm drain inlets in
an effort to reduce the amount of trash that is discharged from private property into the
City's storm drain system or directly into the Arroyo Simi.
After submittal of the implementation plan on February 18, 2019, the City will have
approximately 10 years to complete installation of Full Capture Systems in identified catch
basins based upon inclusion of the Trash Amendment into the City's new MS4 Permit (still
under development but expected to be effective in 2018). The latest that installation would
need to be complete in all identified catch basins would be December 2030.
FISCAL IMPACT
None at this time; however, future expenditures will be necessary. Estimated costs of
individual Full Capture Systems range from $600 to $1,200 per device (includes materials
and installation). Using the original estimate of 138 catch basins, installation costs are
estimated to be $82,800 to $165,600 over the course of ten years. Maintenance costs for
the Full Capture Systems range from $40 per catch basin per cleaning to $110 per catch
basin per cleaning. Catch basins with Full Capture Systems will likely be required to be
cleaned a minimum of three times per year but more likely four times per year at an
estimated cost of $22,080 to $60,720 per year, assuming all 138 catch basins receive a
Full Capture System.

Potential funding sources for the Full Capture Devices include the City's solid waste AB
939 Fees; potential grant applications for litter reduction or stormwater quality
improvements; funding sources for street improvements when/if the City performs street
improvements on streets that include catch basins that will require a Full Capture System.
Also, SB 231, recently signed into law by Governor Brown, permits establishment of
stormwater fees without the voter-approval requirements of Proposition 218. This law may
be subject to litigation.
STAFF RECOMMENDATION
Approve submittal of letter to Regional Board stating that the City intends to comply with
Track 1.

WATER CODE SECTION 13383 ORDER TO SUBMIT METHOD TO COMPLY WITH
STATEWIDE TRASH PROVISIONS; REQUIREMENTS FOR PHASE I MUNICIPAL SEPARATE
STORM SEWER SYSTEM (MS4) PERMITTEES IN THE LOS ANGELES REGION
Dear Sean Corrigan:
On April 7, 2015, the State Water Resources Control Board (State Water Board) adopted
statewide Trash Provisions' to address the pervasive impacts trash has on the beneficial uses of
our surface waters. Throughout the state, trash is typically generated on land and transported to
surface water, predominantly through MS4 discharges. Discharges from Phase I MS4s are
currently regulated through three Phase I MS4 permits issued by the Los Angeles Regional Water
Quality Control Board (Los Angeles Water Board).2 These permits are issued pursuant to section
402(p) of the Federal Clean Water Act.
The Trash Provisions establish a statewide water quality objective for trash and a prohibition of
trash discharge, or deposition where it may be discharged, to surface waters of the State. The
Trash Provisions apply to all surface waters of the State, with the exception of those waters within
the jurisdiction of the Los Angeles Regional Water Quality Control Board (Los Angeles Water
Board) for which trash Total Maximum Daily Loads (TMDLs) are in effect prior to the effective
date of the Trash Provisions.3 As such, this Order is only being issued to those Phase I MS4
Documents pertaining to the amendments to the Water Quality Control Plan for Ocean Waters of California (Ocean
Plan)to control trash and the adoption of Part 1 Trash Provisions of the Water Quality Control Plan for Inland Surface
Waters, Enclosed Bays, and Estuaries of California (ISWEBE Plan) are available on the Water Boards' website at
http.//www.waterboards.ca.gov/water issues/programs/trash control/documentation.shtml .
2 Waste Discharge Requirements for Municipal Separate Storm Sewer System (MS4) Discharges within the Coastal
Watersheds of Los Angeles County, Except those Discharges Originating from the City of Long Beach MS4 (Order
No. R4-2012-0175 as amended by State Water Board Order WQ 2015-0075 and Los Angeles Water Board Order
No. R4-2012-0175-A01, NPDES No. CAS004001); Waste Discharge Requirements for MS4 Discharges from the
City of Long Beach (Order No. R4-2014-0024 as amended by Los Angeles Water Board Order No. R4-2014-0024-
A01, NPDES No. CAS004003); and Waste Discharge Requirements for Storm Water(Wet Weather)and Non-Storm
Water(Dry Weather) Discharges from the MS4s within the Ventura County Watershed Protection District, County of
Ventura and the Incorporated Cities Therein (Order No. R4-2010-0108, NPDES No. CAS004002).
3 In the Los Angeles Region, there are fifteen (15) trash TMDLs for the following watersheds and waterbodies: Los
Angeles River Watershed, Ballona Creek, Malibu Creek Watershed, Santa Monica Bay Nearshore and Offshore, San
Gabriel River East Fork, Revolon Slough and Beardsley Wash, Ventura River Estuary, Machado Lake, Lake
Elizabeth, Lake Hughes, Munz Lake, Peck Road Park Lake, Echo Park Lake, Lincoln Park Lake and Legg Lake.

permittees within the Los Angeles Region whose jurisdictional area is not fully addressed by an
existing trash TMDL.
For Phase I MS4 permittees that have regulatory authority over Priority Land Uses,*4 the Trash
Provisions require implementation of the prohibition through requirements incorporated into the
Phase I MS4 Permit and/or through monitoring and reporting orders. The Los Angeles Water
Board did not amend the Region's existing Phase I MS4 permits, identified in footnote 2, within
the time frame specified by the Trash Provisions. Therefore, the initial steps in planning for the
implementation of the Trash Provisions are required through this Order in accordance with Water
Code section 13383, as specified in the Trash Provisions,5 and as further authorized by Clean
Water Act sections • 308(a) and 402(a) and 40 Code of Federal Regulations parts
122.26(d)(2)(i)(F), (iii)(D), (iv), and 122.41(h). The implementation plans submitted in response to
this Order are subject to approval by the Los Angeles Water Board and, upon approval, shall
become part of approved Watershed Management Programs and Enhanced Watershed
Management Programs and their corresponding monitoring programs in areas covered by such
programs. In other areas, upon approval and pursuant to 40 C.F.R. section 122.41,the monitoring
and reporting elements of the implementation plans shall become part of the permittee's
monitoring and reporting program under the applicable MS4 permits
This Order is issued to implement federal law. The water quality objective established by the
Trash Provisions serves as a water quality standard federally mandated under Clean Water Act
section 303(c)and the federal regulations. (33 U.S.C.§ 1312,40 C.F.R. § 131.)This water quality
standard was specifically approved by U.S. EPA following adoption by the State Water Board and
approval by the Office of Administrative Law. This Order requests information necessary for
municipal permittees to plan for implementation of actions to achieve the water quality standard
for trash. Further, the water quality standard expected to be achieved pursuant to the Trash
Provisions may allow each water body impaired by trash and already on the Clean Water Act
section 303(d) list to be removed from the list, or each water body subsequently determined to be
impaired by trash to not be placed on the list, obviating the need for the development of a total
maximum daily load (TMDL) for trash for each of those water bodies. (33 U.S.C. § 1313(d); 40
C.F.R. § 130.7.) In those cases, the specific actions that will be proposed by the municipal
permittees in response to this Order substitute for some or all of the actions that would otherwise
be required consistent with waste load allocations in a trash TMDL. (40 C.F.R. § 122.44, subd.
(d)(1)(vii)(B).) This Order nevertheless allows municipal permittees to select specific proposed
actions to meet the federal requirements.
The Trash Provision requires Phase I MS4 permittees with regulatory authority over Priority Land
Uses to select a method of compliance with the trash prohibition. Through this Order, the Los
Angeles Water Board requires Phase I MS4 permittees to determine and report their selection of
either the following Track 1 or Track 2 compliance methods:7
1. Track 1: Install, operate, and maintain Full Capture Systems*for the storm drain network that
capture runoff from the Priority Land Uses in their jurisdiction.

Phase I MS4 permittees that select the Track 1 compliance method may discover that there
are locations within their storm drain network where full capture systems cannot be
implemented, or are better implemented within another land use area. The Trash Provisions
allow a Phase I MS4 permittee with regulatory authority over Priority Land Uses to request,
from the Los Angeles Water Board Executive Officer, to substitute one or more Priority Land
Uses with equivalent alternate land uses*8 within the MS4 permittee's jurisdiction.
2. Track 2: Install, operate, and maintain any combination of Full Capture Systems, Multi-
Benefit Projects,* other Treatment Controls,* and/or Institutional Controls` within either the
jurisdiction of the MS4 permittee or the jurisdiction of the MS4 permittee and contiguous MS4
permittees.The MS4 permittee may determine the locations or land uses within its jurisdiction
to implement any combination of controls. Permittees choosing Track 2 must demonstrate
that the approach9 will achieve Full Capture System Equivalency.*
To ensure the compliance method selection is completed accurately, the Los Angeles Water
Board, through this Order, requires the Phase I MS4 permittees to complete and submit the
following:
1. Jurisdictional Maps. Phase I MS4 permittees must develop jurisdictional or watershed maps
identifying Priority Land Use areas, any drainage areas already covered by existing trash
TMDLs,the corresponding storm drain network and associated drainage areas, and proposed
locations for certified Full Capture System installations.
Permittees selecting the Track 1 compliance method and that are proposing alternative land
uses shall identify the alternative land uses on the jurisdictional or watershed map and the
corresponding priority land uses being substituted.
Permittees selecting the Track 2 compliance method may determine the locations or land uses
within their jurisdictions or watershed(s)to implement any combination of controls that achieve
Full Capture System Equivalency. Therefore, the permittee(s) must identify on the
jurisdictional or watershed maps the selected locations or land uses where a combination of
controls, which are identified in Track 2 above, will be implemented to achieve Full Capture
System Equivalency.
These jurisdictional or watershed maps will assist review of the compliance method selection
by the Los Angeles Water Board.
2. Trash Assessments. Phase I MS4 permittees that elect the Track 2 compliance method must
conduct and submit trash assessments to identify existing levels of trash generation.10
8 See definition of Priority Land Uses in enclosed Trash Provisions Glossary.
9 The MS4 permittee may determine which controls to implement to achieve compliance with the Full Capture System
Equivalency. It is, however, the State Water Board's expectation that the MS4 permittee will elect to install Full
Capture Systems where such installation is not cost-prohibitive. (Chapter IV.A.3.a.(2) of the ISWEBE Plan and
Chapter III.L.2.a.(2)of the Ocean Plan).
10 Trash assessments are required pursuant to federal law and regulation as previously indicated, and pursuant to the
monitoring and reporting programs of the three MS4 permits(see Monitoring and Reporting Program No.CI 7388, CI
8052, and CI 6948).
232
City of Moorpark August 18, 2017
Page 4 of 7
Through this Order, the Los Angeles Water Board directs Phase I MS4 permittees selecting
Track 2, at a minimum, to conduct a trash assessment of the Priority Land Use areas, even if
they subsequently select other locations or land uses within their jurisdiction or watershed to
implement any combination of controls that meet Full Capture System Equivalency. If
proposing to select locations or land uses other than Priority Land Uses, the permittee must
also assess trash levels at those locations or land uses and provide a justification
demonstrating that the selected locations or land uses generate trash at rates that are
equivalent to or greater than the Priority Land Uses. The Los Angeles Water Board will
consider the trash assessments and corresponding justification in its approval process."
The Trash Provisions provide two example trash assessment approaches for permittees to
demonstrate Full Capture System Equivalency when a permittee selects the Track 2
compliance method. Phase I MS4 permittees may use alternative methods to demonstrate
Full Capture System Equivalency. One alternative method is the Visual Trash Assessment
Approach, an accepted assessment approach based on on-land visual trash assessments.12
A description of the Visual Trash Assessment Approach13 is enclosed in this Order and may
be used by Phase I MS4 permittees to meet the requirement for a baseline assessment.
Information resulting from the trash assessments is necessary to develop appropriate
requirements and provisions in the Phase I MS4 permits when they are reissued, including:
(1) Establishing a baseline for compliance tracking and determinations,
(2) Establishing interim milestones to demonstrate progress towards 100 percent compliance
with the Trash Provisions within 10 years of the effective date of the implementing permit,14
(3) Evaluating the permittees' planned implementation of Full Capture System Equivalency,
and in
(4)Approving the implementation plan.
Permittees that select the Track 1 compliance method through implementation of certified Full
Capture Systems in all storm drains that capture runoff from all Priority Land Use areas are
not required to conduct trash assessments. Through the Track 1 compliance method, the Los
Angeles Water Board provides a streamlined compliance pathway with annual progress
reporting of Full Capture System installation.
3. Implementation Plan. The implementation plan required by this Order in clause 3 below is
subject to approval by the Los Angeles Water Board Executive Officer.15 A request for an
equivalent alternative land use identified on the jurisdictional or watershed map, per section 1
above, must be submitted within the implementation plan and approved by the Los Angeles
11 In accordance with Permitting Authority's discretional authority under Chapter IV.A.3.d. of the ISWEBE Plan or
Chapter III.L.2.d.of the Ocean Plan.
72 The State Water Board funded an evaluation (through Proposition 84 grant funds) of the on-land visual trash
assessment method as part of the Tracking California's Trash project conducted by the Bay Area Stormwater
Management Agencies Association(BASMAA).The evaluation concluded that if visual assessments were conducted
consistent with the protocol,the method could reliably establish baseline trash levels and detect progress in reducing
trash in MS4 discharges over time.

Subject: Statewide Trash Provisions Compliance Selection
Dear Mr. Unger:
The City has received your letter dated August 18, 2017, titled "Water Code Section 13383
Order to Submit Method to Comply with Statewide Trash Provisions; Requirements for Phase I
Municipal Separate Storm Sewer System (MS4) Permittees in the Los Angeles Region.
This letter serves as the City's response to your request for compliance selection. The City
has determined that it has selected Track 1: Install, operate, and maintain Full Capture Systems
for the storm drain network that capture runoff from the Priority Land Uses in their jurisdiction. As
noted in your letter, Phase I MS4 permittees that select the Track 1 compliance method may
discover that there are locations within their storm drain network where full capture systems
cannot be implemented, or are better implemented within another land use area. The Trash
Provisions allow a Phase I MS4 permittee with regulatory authority over Priority Land Uses to
request, from the Regional Board's Executive Officer, to substitute one or more Priority Land
Uses with equivalent alternate land uses within the MS4 permittee's jurisdiction.
As the City prepares its Implementation Plan, due to the Regional Board by February 18, 2019, it
may submit a request to substitute an alternative to the Priority Land Uses definition of a high
trash area along with justification for such a request. In addition, as has been indicated by
