TO: Members of the Newport Beach City Council
FROM: Dave Kiff, Assistant City Manager
SUBJECT: New Regulations on Stormwater and Urban Runoff:
Proposed 5 -Year Municipal Permit
RECOMMENDED Discuss proposed Permit, suggest Council response in advance of December
ACTION: 19, 2001, Board hearing date.
WHAT'S NEW In a conversation with Santa Ana Regional Board Executive Officer Jerry
SINCE 11 -13 ?: Thibeault, Thibeault told me that it was unlikely that the Regional Board would
defer its planned December 19, 2001 action to adopt the proposed Permit until
early 2002. The City missed the November 19, 2001 official comment deadline
for the November 5, 2001 version of the Permit, but we can still submit any
formal correspondence to the Board between now and December 19, 2001.
On November 16, 2001, the State Water Resources Control Board heard an appeal
of the San Diego Region's Permit. According to news services, the State Board
upheld most of the San Diego Permit, including requirements for on -site
treatment and more stringent prohibitions on commercial and residential runoff
(see article in Appendix C). As previously discussed, the San Diego Permit is
generally viewed as being more directive than the Santa Ana Permit.
KEY ISSUES FOR Judging from the CounciI's discussion of certain provisions of the proposed
THE COUNCIL'S Santa Ana Permit, the Council will likely want to talk more about the following
STUDY SESSION: issues:
Prohibited Discharges
• Does the proposed Permit expressly prohibit discharges from commercial
hosedowns of sidewalks? If so, what should the City's position be? Should
the City help businesses comply with these new regulations? If so, how?
• Is the proposed Permit's exemptions of some residential discharges (car
washing, excessive irrigation, hosing down of driveways and yards)
appropriate? Should the City adopt requirements that are more stringent
than the proposed Permit?
On -Site Treatment (aka SUSMPs)
• The proposed Permit, unlike its neighboring permits in South Orange
County, San Diego, and Los Angeles, does not expressly, require on -site
treatment of runoff from "first flush" rain events when a developer submits
an application for new development or significant redevelopment. Should

the City ask the Santa Ana Board to adopt a SUSMP requirement for our
Region's Permit?
Inspections
• The proposed Permit sets up new obligations on cities to provide routine
inspections of certain construction, commercial, and industrial sites. Some
believe the Permits requirements here are too lax; others say they're too
stringent. What should the City's position be as to the frequency of
inspection and as to which construction, commercial, and industrial sites are
"high priority" threats to water quality?

M. DISCHARGE LIMITATIONS/PROHIBITIONS
1. In accordance with the requirements of 40 CFR 122.26(d)(2)(i)(B) and 40 CFR 122.26(d)(2)(i)(F), the
permittees shall prohibit illicit /illegal discharges (non -storm water) from entering into the municipal
separate storm sewer systems.
2. The discharge of storm water from the MS4s to waters of the United States containing pollutants that
have not been reduced to the maximum extent practicable is prohibited.
3. The permittees shall effectively prohibit the discharge of non -storm water into the MS4s, unless such
discharges are authorized by a separate NPDES permit or as otherwise specified in this provision.
Certain discharges identified below need not be prohibited by the permittees. If however, any of these
discharges are identified by the permittees or the Executive Officer as a significant source of pollutants,
coverage under the Regional Board's De Minimus permit may be required.

n. Emergency fire fighting flows (i.e., flows
necessary for the protection of life and property)
do not require BMPs and need not be prohibited.
However, where possible, when not interfering
with health and safety issues, BMPs should be
considered (also see Section xlx, Provision 4);
o. Waters not otherwise containing wastes as
defined in California Water Code Section 13050

list of impaired waters.
NPDES Item
Nmernber 27, 2001
Page 6
h. Parking lots of 5,000 square feet or more exposed to storm water. Parking lot is defined as a land
area or facility for the temporary storage of motor vehicles.
2. The permittees are encouraged to include in the WQMP the development and implementation of
regional and /or watershed management programs that address runoff from new development and
significant re- development The WQMP shall include BMPs for source control, pollution prevention,
and /or structural treatment BMPs. For all structural treatment controls, the WQMP shall identify the
responsible party for maintenance of the treatment system, and a funding source or sources for its
operation and maintenance. The goal of the WQMP is to develop and implement practicable programs
and policies to minimize the effects of urbanization on site hydrology, urban runoff flow rates or
velocities and pollutant loads. This goal may be achieved through watershed -based structural treatment
controls, in combination with site - specific BMPs. The WQMP shall reflect consideration of the following
goals, which may be addressed through on- site -and /or watershed -based BMPs.
a. The pollutants in post - development runoff shall be reduced using controls that utilize best
available technology (BAT) and best conventional tecnology (BCT).
b. The discharge of any listed pollutant to an impaired waterbody on the 303(d) list shall not cause
an exceedence of receiving water quality objectives.
3. During the time that the WQMP is being revised, the permittees shall implement their existing
requirements for new development (Appendix G of the DAMP). If the Executive Officer does not
approve the revised WQMP by October 1, 2003, as meeting the goals proposed in XII.B.2, above and
providing an equivalent or superior degree of treatment as the sized criteria outlined in XII.B.3, below,
structural BMPs shall be required for all new development and significant redevelopmenfl. Minimum
structural BMPs must either be sized to comply with one of the following numeric sizing criteria or be
deemed by the Principal Permittee to provide equivalent or superior treatment, either on a site basis or a
watershed basis:
A. Volume
Volume -based BMPs shall be designed to infiltrate, filter, or treat either:
1. The volume of runoff produced from a 24 -hour, 85th percentile storm event, as
determined from the local historical rainfall record; or
2. The volume of annual runoff produced by the 85th percentile, 24 -hour rainfall event,
determined as the maximized capture storm water volume for the area, from the
formula recommended in Urban Runoff Quality Management WEF Manual of Practice
No. 23 /ASCE Manual of Practice No. 87 (1998); or
3. The volume of annual runoff based on unit basin storage volume, to achieve 80% or
more volume treatment by the method recommended in California Stormwater Best
Management Practices Handbook - Industrial /Commercial (1993); or
4. The volume of runoff, as determined from the local historical rainfall record, that
achieves approximately the same reduction in pollutant loads and flows as achieved by
mitigation of the 85th percentile, 24 -hour runoff event,
OR
NPDES Item
November 27, 2001
Page 7
B. Flow
Flow -based BMPs shall be designed to infiltrate, filter, or treat either:
1. The maximum flow rate of runoff produced from a rainfall intensity of 0.2 inch of
rainfall per hour; or
2. The maximum flow rate of runoff produced by the 85th percentile hourly rainfall
intensity, as determined from the local historical rainfall record, multiplied by a
factor of two; or
3. The maximum flow rate of runoff, as determined from the local historical rainfall
record, that achieves approximately the same reduction in pollutant loads and flows
as achieved by mitigation of the 85th percentile hourly rainfall intensity multiplied
by a factor of two.
C. Groundwater Protection
Any structural infiltration BMPs shall meet the following minimum requirements:
1. Use of structural infiltration treatment BMPs shall not cause or contribute to an
exceedance of groundwater water quality objectives.
2. Source control and pollution prevention control BMPs shall be implemented to
protect groundwater quality.
3. Structural infiltration treatment BMPs shall not cause a or pollution as defined in
Water Code Section 13050.
4. The permittees may propose any equivalent sizing criteria for treatment BMPs or other controls that will
achieve greater or substantially similar pollution control benefits. In the absence of approved equivalent
sizing criteria, the permittees shall implement the above stated sizing criteria.
5. If a particular BMP is not technically feasible, other BMPs should be implemented to achieve the same
level of compliance or if the cost of BMP implementation greatly outweighs the pollution control
benefits, the permittees may grant a waiver of the numeric sizing criteria. All waivers, along with waiver
justification documentation must be reported to the Regional Board in writing within 30 days. The
permittees may propose to establish an urban runoff fund to be used for urban water quality
improvement projects within the same watershed that is funded by contributions from developers
granted waivers. If it is determined by the Regional Board that waivers are being inappropriately
granted, this Order may be reopened to modify these waiver conditions.
6. The obligation to install minimum structural BMPs at new development is met if, for a common scheme
of development, BMPs are constructed with the requisite capacity to serve the entire common scheme,
even if cerain phases of the common scheme may not have BMP capacity located on that phase in
accordance with the requirements specified above.

Appendix C
State backs plan for more strict regulations on storm -drain runoff
By Michael Gardner
COPLEY NEWS SERVICE
November 16, 2001
SACRAMENTO -- State water - quality regulators yesterday upheld a sweeping plan to control urban runoff
in San Diego County that cracks down on builders, gardeners and motorists. The unanimous decision by
the Water Resources Control Board was a blow to the building industry and some cities that had
dispatched teams of lawyers to fight the new rules.
In a minor concession to opponents, the water board agreed to exempt, at least initially, new gas stations
from the tougher standards. Once the plan is fully implemented next year, cities and the county must
impose strict measures to stem the tide of pollutants funneled by storm drains to coastal waters.
For builders, that means designing new subdivisions to minimize runoff, such as limiting pavement and
concrete surfaces. They also may be required to install traps and filters on storm drains. Larger
developments could be forced to provide costly treatment centers or holding ponds.
The new controls will touch every facet of life in San Diego County. Puttering in the garden? Plan on
reducing fertilizers and pesticides. Does the clunker need a new radiator? Expect to be asked to patch
the leak and clean up the coolant. Washing the car? Dump the bucket inside rather than outside. Draining
the pool? You no longer will be allowed to pump chlorine- saturated water down street gutters.
"It's bringing the Clean Water Act right to the front door," said Paul Singarella, an attorney representing
homeowner associations statewide. City and county officials say the new rules are more likely to result in
an aggressive public awareness campaign, not a neighborhood storm -water police force. In return, the
coastal economy will be protected along with the health of the public and the environment, water - quality
regulators said.
Alarmed at mounting water pollution and beach closures, the San Diego Regional Water Quality Control
Board in February adopted a comprehensive plan requiring the county, its 18 cities and the Port District to
do a betterjob of controlling urban runoff. The San Diego Building Industry Association, later joined by
several cities, homeowner groups and other construction interests, appealed to the state. Builders are
unsure whether to pursue their case in court.
David Mulliken, an attorney for the builders, said he was disappointed that the state board did not limit the
regional board's enforcement powers. The San Diego plan allows water - quality regulators to block
projects or fine developers for polluting -- even if they demonstrate good -faith attempts to prevent
contaminants and debris from reaching storm drains.
But Phil Hammer, an environmental scientist for the regional board, said existing policies allow regulators
to defer punishment if the offending party is attempting to comply.
For new gas stations, the state board merely said San Diego regulators need to refine their proposal.
"We didn't say no. We said come back," said Art Baggett, chairman of the state board. Overall, "we've
upheld 97 percent of what the regional board did," Baggett said.
ITEM 17
TO: Members of the Newport Beach City Council
FROM: Dave Kiff, Assistant City Manager
SUBJECT: New Regulations on Stormwater and Urban Runoff: 11'ti1 �O)
Proposed 5 -Year Municipal Permit
RECOMMENDED 1) Authorize the Mayor to issue a letter to the California Regional Water
ACTIONS: Quality Control Board, Santa Ana Region, stating the City's position that the
Permit should:
A. Require measurable increases in awareness within the Public Education
section, similar to the San Diego Permit's language;
B. Require structural BMPs, including onsite treatment of runoff ( SUSMP)
for certain new development and significant redevelopment;
C. Specifically authorize cities to - at cities' discretion -- prohibit excessive
runoff from residential areas and landscape irrigation flows;
D. Maintain and support the Permit's language relating to Inspections,
General Plan review and General Plan amendment; and
E. Direct all jurisdictions in the Permit area to complete once a week street
sweeping with parking enforcement along each sweeper route.
2) Direct the General Plan Update Committee to include the proposed Permits
requirements relating to general plans in the scope of the General Plan
Update.
3) Direct City staff to analyze and report back on the environmental and
economic effects of adopting a citywide SUSMP or structural BMP
requirement in advance of any similar action by the Regional Board.
4) Approve Budget Amendment #_ increasing the City's contribution to the
County of Orange's NPDES administration by $16,291.14 from $20,000 to
$36,291.14.
QUICK SUMMARY Cities are directed to control runoff entering storm drain systems (called
AND TERMS: Municipal Separate Storm Sewer Systems or "MS4s ") so that the runoff does not
hurt water quality at the end of the pipe. Newport Beach has more than 104
miles of MS4s that enter Newport Bay or the Pacific Ocean at about 212 locations.
Newport Bay is an impaired water body, meaning that it has been placed on the
federal Clean Water Act's Section 303(4) List due to excessive Sediment, nutrients,
fecal coliform, and toxic materials. The Newport Beach Marine Life Refuge Area
of Special Biological Significance (ASBS) lies off the coast of Little Corona.

A 5 -year permit (Municipal Permit) issued by the California Regional Water .\
Quality Control Board, Santa Ana Region (Regional Board) regulates the discharge
of runoff out of a city's storm drain system. On December 19, 2001, the Regional
Board will likely adopt a new 5 -year permit (through 2006) for the City, the
County, and 24 other co- permittee cities. The permit tells us how to limit urban
runoff, enforce and report violations, educate residents and businesses, and to
maintain Permit compliance.
The proposed permit (Permit) has generated controversy from environmental
groups (who argue that the Permit is too soft) and business groups (who argue
that parts of the Permit are too tough). This staff report describes the Permit and
identifies areas of the Permit that we believe deserve modification - sometimes
to a tougher standard, sometimes to a lesser standard.
This staff report is extensive - readers who wish to get to a summary of the
issues within the Permit should turn immediately to Appendix A.
DETAILED When Governor Ronald Reagan and the California State Legislature approved
BACKGROUND: the Porter - Cologne Water Quality Control Act of 1970 (Porter - Cologne), it was one
of the nations first comprehensive attempts to improve surface and recreational
water quality within a state. Porter - Cologne grants the State Water Resources
Control Board (State Board) and its nine Regional Boards broad powers to protect
water quality. Porter - Cologne is the primary vehicle to implement the federal
clean water laws in California.
After creating the US Environmental Protection Agency in 1970, President Nixon
and the US Congress passed the 1972 federal Water Pollution Control Act (now
called the Clean Water Act or CWA). Among other things, the CWA:
• Stated the nation's goal that "the discharge of pollutants into navigable
waters be eliminated by 1955."
• Set up a system of permits for any wastewater discharge under US EPA - a
system called the National Pollutant Discharge Elimination System (NPDES).
• Declared that wastewater must be treated with the best technology
economically available regardless of the condition of the receiving water.
Performance Standards. NPDES says that all facilities that discharge pollutants
from any point source into waters of the United States must have a permit. It
introduced a series of important terms into the water quality arena, including:
• Point Source. A point- source discharge is one from a discernible, confined
and discrete conveyance, such as a pipe, ditch, or channel. Urban runoff-
while not starting from a known source - becomes a point- source discharge
once it enters an MS4.
• Non -Point Source. A non -point source discharge is one from something less
identifiable, like agriculture, forestry, or mining operations.
• Maximum Extent Practicable (MEP). MEP means reducing pollutants "to the
maximum extent feasible, taking into account ... competing factors,
including ... (the) gravity of the problem, technical feasibility, fiscal
feasibility, public health risks, societal concerns, and social benefits"
NPDES Rein
No Ynber 13, 2001
Page 3
• Best Management Practices (BMPs). BMPs are "practices maximized in
efficiency for the control of storm water runoff pollution" and include
actions like sandbagging graded land to limit erosion, installing filters in
catch basins, and street - sweeping using regenerative air sweepers.
Three Permits to Know. NPDES introduced three types of permits to the water
quality lexicon. These include:
• Municipal Stormwater Permits. Amendments to the CWA in 1987
established schedules so that municipal storm water discharges would be
regulated by NPDES permits. As such, stormwater - defined as any wet- or
dry- weather flow into a municipal separate storm sewer system (MS4) was a
regulated point - source. Discharges from MS4s were required to have controls
to reduce pollutant discharges to the maximum extent practicable (MEP).
An MS4 is a system of conveyances (including roads with drainage systems,
municipal streets, catch basins, curbs, gutters, ditches, man -made channels,
or storm drains) owned or operated by a city that is designed for collecting
storm water and that discharges into waters of the United States. Newport
Beach operates a 104 -mile long MS4.
MS4s' permits are similar to many other NPDES permits - the permits
contain limits on what can be discharged, monitoring and reporting
requirements, and other provisions to ensure that the discharge does not
hurt water quality or people's health. The Permit referred to in this report is
a municipal stormwater permit.
• Construction Permits. The State Board also issues a blanket State General
Construction Activity Stormwater Permit that applies to construction
activity affecting 5 or more acres. Regional Boards enforce construction
permits, but cities are obligated to do so in cooperation with the RBs.
Today, eleven sites in Newport Beach (including Hoag Hospital, Fletcher
Jones Motorcars, One Ford Road, the Balboa Bay Club, 500 Superior Avenue,
and the Bonita Canyon Sports Park) operate under the statewide
Construction Permit issued by the Regional Board. The Newport Coast
contains another 18 construction permit sites.
• Industrial Permits. Regional Boards regulate runoff from most industrial
activities (manufacturing and more) via the General Industrial Activities
Stormwater Permit. Newport Beach has just two sites (Conexant Systems
and Hixson Metal) that have industrial permits.
Regional Boards - Two for Orange Coin. As noted, the State Board delegates
much of the State's water quality responsibility to its nine Regional Boards (RBs).
Because the state's nine regions are divided by watershed boundaries, not by
political boundaries, Orange County's water quality issues are addressed by two
regional boards - Santa Ana Regional Board and the San Diego Regional Board.

I Regional Boards are responsible for reviewing, amending, approving, and
I enforcing municipal NPDES 5 -year permits, but the California Water Code
actually prohibits boards from dictating actions or behaviors. Section 13360 of
the Water Code reads as follows:
"No waste discharge requirement or other order of a regional board ... shall specify
the design, location, hype of construction, or particular manner in which compliance
may be had with that requirement, order, or decree, and the person so ordered shall
be permitted to comply with the order in any lawful manner."
Developing the 5 -Year Permit - How it Works. As "lead permittee" for the 5-
year Permit, the County of Orange first develops a draft Drainage Area
Management Plait (DAMP). The DAMP describes how the County and the cities
of Anaheim, Brea, Buena Park, Costa Mesa, Cypress, Fountain Valley, Fullerton,
Garden Grove, Huntington Beach, Irvine, La Habra, La Palma, Laguna Hills,
Laguna Woods, Lake Forest, Los Alamitos, Newport Beach, Orange, Placentia,
Santa Ana, Seal Beach, Stanton, Tustin, Villa Park, Westminster, and Yorba Linda
will attempt to control urban runoff. Both Laguna Woods and Lake Forest are
within both Regional Boards' jurisdictions. The cities and the County serve a
population of approximately 2.8 million and occupy an area of approximately
786 square miles.
The permittees submit the DAMP about a year before the anticipated expiration
of the operative 5 -Year Permit. The Regional Board then reviews the DAMP and
issues proposed or tentative Waste Discharge Requirements (WDRs) within a
tentative Order of the Regional Board. After a series of workshops and public
hearings, the Regional Board and its staff may revise the WDRs and the Order to
reflect the comments received. The last step is formal adoption by the Board of
the WDRs and the Order.
The current Order (Order #96 -31) expired on March 1, 2001. On September 1,
2000, the County applied for a new Permit. On March 5, 2001, the Board
extended Order # 96 -31 until the Board could adopt a new Permit. Order #01 -20
is now under consideration by the Santa Ana Regional Board and is in its third
draft (November 5, 2001). A similar order - Order #01 -02 - is under
consideration by the San Diego Regional Board.
KEY PERMIT ISSUES: While urban runoff management may seem arcane to some, the discussion over
the boards' consideration of the San Diego Permit and the Santa Ana Permit has
been heated. Municipalities, environmental groups, the building industry, and
others have scrutinized the permits and actively lobbied for modifications. Most
people believe that the Santa Ana Permit is less restrictive and less directive than
the San Diego /South Orange County Permit,
The areas of interest to Newport Beach are as follows (please note that when this
staff report refers to "Permit," it means the Santa Ana Permit):
NPDES Item
November 13, 2001
Page 6
A - Municipal BMPs. Today we are directed to control contaminated runoff via
catch basin cleaning, street sweeping, stenciling of catch basins, hazardous
materials spill responses, and fertilizer and pesticide BMPs. The proposed
Permit directs us to:
• Develop and distribute "model maintenance practices" for public agency
activities plus pollution prevention measures;
• Inspect and maintain 80% of our "drainage facilities' annually, with 100% of
the facilities "addressed" every two years;
• Look for places where we can install natural water quality wetlands;
• Train field staff and contracted field staff.
Horn should Newport Beach Respond? Today, only Newport Beach, Santa Ana, and
Laguna Beach have daily street sweeping in commercial areas. Most other cities
sweep commercial areas weekly. Almost all cities - including Newport - also
sweep residential areas weekly. While the current enforceable DAMP
(developed in 1993) directs only monthly street sweeping, all cities (and now the
County) report bi- monthly sweeping at a minimum. Some cities include parking
enforcement with sweeping activities.
While the Regional Board is prohibited from telling us what to do, I believe that
protecting water quality to MEP means mandatory street sweeping at least once
a week in all areas of a city. I believe, too, that parking enforcement should be
mandated along each street sweeping route - though a period of time using
advisory notices may be appropriate before ticketing. The Council may wish to
urge the Regional Board and upstream cities to, once the "model maintenance
practices" are out, require (at a minimum) weekly street sweeping in commercial
and residential areas with full parking enforcement.
As to drainage facilities like v- ditches and catch basins, MEP dictates that we
inspect and clean each catch basin and v -ditch in our jurisdictions at least once a
year. The Permit appropriately directs all permittees to move towards more
"aggressive" catch basin cleaning by 2004 -05. I don't recommend a change here
given the Board's encouragement to clean more basins soon.
B — Public Education. Nothing in the current permit requires us to educate our
residents and businesses as to water quality issues. The proposed Permit says
that "the goal of the public and business education program shall be to target
100% of the residents including businesses, commercial, and industrial
establishments." Interestingly, the San Diego proposed permit directs the
permittees to:
...implement an Education Component using all media as appropriate to:
(1) measurably increase the knowledge of the target communities regarding MS4s,
impacts of urban runoff on receiving waters, and potential BMP solutions for the
target audience; and to
(2) measurably change the behavior of the target communities and thereby reduce
pollutant releases to the MS4s and the environment.
NPDES 11ern
November 13, 2001

j How should Newport Beach Respond? The Council should ask the Santa Ana Board
I to adopt the San Diego Permits language on education since achieving
measurable increases in knowledge is more meaningful than setting a "goal" of
targeting 100% of the residential and commercial base. Measurement may be
through special pre- and post - inquiries of specifically- targeted populations.
C - Newport Beach's Water Quality Ordinance. The proposed Permit directs us
to review the water quality ordinance that each city adopted in 1996 or 1997.
Newport Beach adopted our Ordinance (Chapter 14.36 of the Newport Beach
Municipal Code) in November 1997. Issues raised by the Permit are as follows:
I — Discharge Exemptions. Today the City's Water Quality Ordinance has a
general prohibition against polluted discharges ( "no person shall cause, allow
or facilitate any prohibited discharge.., "), but it contains a series of 10
exemptions, including:
• Storm water;
• Discharges permitted under separate NPDES permits;
• Discharges from property where BMPs have been followed;
• Discharges into storm drains from water line flushing, fire fighting
activities, landscape irrigation systems, diverted stream flows, more;
• Discharges from potable water sources, passive foundation drains,
building roof runoff, lawn watering, noncommercial vehicle and boat
washing, noncommercial animal washing, dechlorinated swimming pool
discharges, more;
• Discharges of reclaimed water generated by a lawful treatment facility,
public street wash waters when related to cleaning and maintenance by,
or on behalf of, the City; and
• Discharges for which the discharger has reduced to the extent feasible
the amount of pollutants in such discharge.
The proposed Permit maintains most of these exemptions, yet directs us to
review our Ordinance by July 1, 2003 to determine the effectiveness of the
Ordinance in prohibiting the following discharges into the storm drain system:
• Sewage;
• Wash water from gas stations and auto service stations;
• Discharges from the cleaning of equipment, autos, more;
• Wash water from mobile detailers, steam and pressure cleaning, more;
• Wash water from cleaning City and commercial parking lots, streets,
sidewalks, patios, plazas, more;
• Runoff from trash receptacles;
• Pool discharges with chlorine;
• Pet waste, yard waste, litter, debris, sediment; and
• Restaurant or food processing waste.
II - Enforcement. Today, the NBMC says that a person who violates the Water
Quality Ordinance may be subject to:
S Administrative Remedies - notices of violation (NOVs), Administrative
> Compliance Orders (ACOs), Cease and Desist Orders (CDOs), City
abatement, and City cost recovery;
NPDES I fern
Nooernber 13, 2001
Page 8
• Nuisance Abatement -- emergency City abatement, full City
reimbursement of costs, and a nuisance lien;
• Penalties and Fines for consecutive violations ($100, $200, and $500);
• Citation including arrest;
• Injunctions; and
• Penalties under the CWA.
The proposed Permit asks us to include sanctions in our Ordinance. I believe
that our Ordinance already contains appropriate sanction language, but the wide
range of prohibited discharge exceptions in the Ordinance make it difficult to
apply any sanctions. Since the Ordinance's adoption in 1997, the City has taken
more than 100 enforcement actions - they break down as follows:
• Five Notices of Non - Compliance;
• 108 Administrative Citations (since June 2000);
• $10,800 in fines (approximately); and
• One criminal case pending with District Attorney's Office
How should Newport Beach Respond? We will need to complete the Ordinance
review. I believe that the provision of the proposed Permit that directs us to
prohibit certain discharges is adequate, yet it continues to leave some residential
wash water and irrigation overflows untouched. The Permit also leaves it to our
discretion as to whether or not we want to clearly prohibit discharges from
commercial (and some residential) hose -downs - as an alternative, it suggests
using BMPs to limit these discharges. Depending upon progress after 12 -18
months, the Council may wish to ask the Board to consider language within the
permit that directs localities to limit excessive flows from residential activities,
including car washing and irrigation. As noted, Newport Beach may not have to
amend the enforcement section of our Water Quality Ordinance as a result of the
proposed Permit's anticipated adol2tion.
D — New Development and Significant Redevelopment. The proposed Permit
makes significant changes to the current permit with regard to land use
planning. These issues are as follows:
I - Planning /CEOA Process Review. We will be directed to - by December 19,
2002 - review planning procedures and our California Environmental Quality
Act (CEQA) processes to ensure that they address pollutants and runoff. It
urges the development of a runoff BMP checklist and training for project
proponents. These impacts will have to be identified and addressed during
CEQA review - the potential:
1. Impact of construction on storm water runoff;
2. Impact of post - construction activity on storm water runoff;
3. For discharge of storm water from areas from material storage, vehicle or
equipment fueling, vehicle or equipment maintenance (including
washing), waste handling, hazardous materials handling or storage,
delivery areas or loading docks, or other outdoor work areas;
4. For discharge of storm water to impair the beneficial uses of the receiving
waters or areas that provide water quality benefit;
5. For significant changes in the flow velocity or volume of storm water
runoff that can cause environmental harm; and
The Nayort Beads
Marine Life Refige ASKS
J,
NPDES I tern
November 13, 2001
Page 9
6. For significant increases in erosion of the project site or surrounding areas.
11- General Plan Amendments. By July 1, 2004, the Permit directs us to
incorporate watershed protection principles and policies into the General Plan
and related documents (such as Development Standards, Zoning Codes,
Conditions of Approval, Development Project Guidance) and provide the
Regional Board with proof of this action. These principles and policies shall
include ways to:
1. Limit disturbance of natural water bodies and drainage systems; conserve
natural areas; protect slopes and channels; minimize impacts from storm
water and urban runoff on natural drainage systems and water bodies;
2. Minimize changes in hydrology and pollutant loading; require
incorporation of controls to mitigate increases in pollutants; ensure that
post - development runoff rates and velocities from a site maintain or
reduce pre - development downstream erosion, and protect stream habitat;
minimize the quantity of storm water directed to impermeable surfaces
and the MS4s; maximize the percentage of permeable surfaces to allow
more percolation of storm water into the ground;
3. Preserve wetlands, riparian corridors, and buffer zones; establish
reasonable limits on the clearing of vegetation from the project site;
4. Encourage the use of water quality wetlands, biofiltration swales,
watershed -scale retrofits, and more;
5. Provide for appropriate permanent measures to reduce storm water
pollutant loads in storm water from the development site; and
6. Establish development guidelines for areas particularly susceptible to
erosion and sediment loss.
111- WQMPs. The Permit requires Water Quality Management Plans
(WQMPs) that limit runoff from these types of developments:
• Anything that adds 5,000 sf of impervious surface;
. Housing of more than 5 units;
• New commercial construction (100,000 sf or more);
• Parking lots of more than 5,000 sf;
• Hillside development on 10,000 sf or more located on areas with known
erosive soil conditions or where the slope is 25% or more;
• New developments of more than 2,500 sf of impervious surface within 200'
of an Area of Special Biological Significance (Buck Gully);
• New restaurants where land area is 5,000 sf or more; and
• All new retail gas outlets and auto repair shops.
A WQMP would be standards for these developments that limit water quality
impacts, including BMPs for source control, pollution prevention, "and /or'
structural treatment BMPs. Structural treatment BMPs typically mean systems
on the property to treat, clarify, or capture runoff from the first 0.75 - 0.80" of
any one 24 -hour rain event. Some refer to this as a Standard Urban Stormwater
Management Plan or SUSMP.
Structural BMPs have been a major point of contention in the Permit, since it
does not have a specific SUSMP requirement. The San Diego Permit and the
LA Permit both require SUSMPs immediately. Those who support a SUSMP
NPDES ]tern
November 13, 2001
Page 10
requirement say that SUSMPs meet the MEP standard. Those who oppose a
SUSMP requirement say it is an onerous obligation on new development.
Our Permit allows us to use a WQMP to direct developers to install systems
that may or may not involve on -site treatment However, if by October 2003
the Regional Board's Executive Officer (EO) doesn't agree that our WQMPs
treat or limit runoff as well as some SUSMPs, the EO can incorporate structural
BMPs into the Permit that filter or treat runoff from a 24 -hour, 85th percentile
storm event.
How should Newport Beach Respond? The proposed Permit's recommendations
regarding General Plan review and amendments are very sound. The Council
could give specific direction to the General Plan Update Committee to include
water quality and watershed impacts in the General Plan update.
As to WQMPs and SUSMPs, the California Coastal Commission, in several recent
cases, currently requires onsite treatment of storm flows when it issues a coastal
development permit (CDP) for a large new project. Since much of the city is
within the Coastal Zone and subject to these Commission directives, the Council
may wish to consider adopting policies today within the city that require
structural BMPs providing for the onsite treatment of the first 85% of rain in a 24-
hour rain event for:
• New commercial construction (50,000 sf or more);
• Housing of more than 5 units;
• Parking lots of more than 5,000 sf;
• Significant redevelopment (adding 3,000 sf or more of impervious surface);
• New restaurants where land area is 5,000 sf or more; and
• All new retail gas outlets and auto repair shops.
These standards could automatically apply unless the project applicant can
prove that a SUSMP is impossible to install and that an alternative method - like
a privately - maintained direct storm drain to sewer diversion - is as or more
effective than on -site treatment.
The Council may wish to consider advocating before the Regional Board that
structural BMPs and numeric sizing criteria be applied immediately for all new
construction and significant redevelopment. Taking such a position will be
controversial with some in the development community. However, if our
upstream neighbors are subject to less stringent standards than Coastal Zone
cities, we may not - as a watershed — be able to meet the very stringent Fecal
Coliform TMDL standards. As extensive new development occurs upstream
without SUSMPs, Newport Beach may be left shouldering a large part of the
TMDL's cost burden in the years to come.
E - Inspections. This section of the proposed Permit requires cities to identify
and then prioritize each construction site, certain commercial sites, and each
industrial site in the city as a high, medium, or low threat to water quality. Once
we prioritize sites, we must then inspect each site on a scheduled basis.
NPDES Item
November 13, 2001
Page 11
/ 1- Inspections of Construction Sites. The Permit defines a construction site as
/ one for which we have issued a building or grading permit and site activities
include soil movement, uncovered storage of materials, mixing of concrete
products, and more. The Permit defines a high priority construction site at a
minimum as one that is 50+ acres or is more than 5 acres and tributary to a
Section 303(d) List water body "listed for sediment..." Any site within 500 feet
of an Area of Special Biological Significance (ASBS) is also high priority.
Construction sites of 5 or more acres in Newport Beach will be "high priority"
if they drain into Upper Newport Bay, since all of Upper Newport Bay is on
the 303(d) list for sediment. Also, sites within 500' of the Crystal Cove ASBS or
the Newport Beach Marine Life Refuge ASBS (Poppy Ave southward) will be
high priority. Thus, the locations where construction sites may be de facto
designated as high - priority threats to water quality will be sites of 5+ acres in:
• Westcliff and Dover Shores,
• Santa Ana Heights, Bayview Heights;
• Eastbluff, the Bluffs, and Newport North
• Portions of Fashion Island
• Big Canyon
• Bonita Canyon and Newport Ridge North
• Newport Ridge, Newport Coast, and Pelican Point
• Spyglass Ridge, Harbor View, Harbor Ridge
...and any size construction site within 500' of the shoreline near Poppy
Avenue southward (parts of CDM, Cameo Shores, and the Newport Coast).
Medium- and low- threat sites are not defined in the permit. The following
schedule applies to the sites during October 1 through April 30:
• High Priority Sites - monthly;
• Medium Priority Sites - twice per wet season;
• Low Priority Sites -once per wet season.
During dry season, we must inspect each site enough to ensure control of
runoff. Inspections must include compliance with grading ordinances and
permits and reviews of erosion control and BMP implementation plans. Sites
out of compliance would be reported to the RB within 24 hours, sanctioned,
including monetary penalties, and require weekly follow -ups.
In 2000 -01, about 3,500 permitted construction sites existed in Newport Beach.
If the Permit was in place in 2000 -01, during October 1, 2000 through April 30,
2001, TBD sites would have had to be inspected monthly to evaluate erosion
control and related BMPs that reduce runoff.
11 - Inspections of Commercial Facilities. The Permit directs us to inventory
these types of commercial businesses:
• Auto repair, fueling, or cleaning;
• Any vehicle repair or painting;
• Mobile auto or other vehicle washing;
• Mobile drape, carpet, or furniture cleaning;
• Mobile high pressure or steam cleaning;
NPDES I fern
November 13, 2001
Page 12
• Painting and coating;
• Nurseries and greenhouses;
• Landscape and landscape irrigation;
• Pool and fountain cleaning; and
• All commercial sites within 500' of an ASBS.
Like construction sites, the Permit directs us to prioritize each business listed
above as to whether it is a high, medium, or low threat to water quality. We
are directed to choose our own inspection frequencies and priorities according
to the relative threat to water quality. We are to inspect each high priority site
at least once by July 2003.
A water quality inspection will look at each business':
• Material and waste handling and storage;
• Pollutant control BMP implementation and maintenance; and
• Evidence of past or present unauthorized discharges.
Sites discovered to be out of compliance will require monthly re- inspections,
reports to the Regional Board within 24 hours, monetary sanctions, and re-
inspections at least once a month. When the business meets standards, they go
on "probation" and have visits once every four months for a year.
Newport Beach has about TBD of these types of businesses.
III - Inspections of Industrial Facilities. The Permit directs us to inventory all
"industrial businesses" within city limits. Like construction and certain
commercial sites, the Permit directs us to prioritize each industrial site as to
whether it is a high, medium, or low threat to water quality. High priority
sites are those subject to the statewide Industrial Permit (we have two of these)
and facilities "with a high potential for or a history of unauthorized
discharges..." We are to follow this schedule for industrial site inspections:
• High Priority Sites - annual inspections, with all complete by July 2003;
• Medium Priority Sites - once every two years;
• Low Priority Sites - once during the Permit term.
A water quality inspection will look at each business':
• Material and waste handling and storage;
• Pollutant control BMP implementation and maintenance; and
• Evidence of past or present unauthorized discharges.
Sites discovered to be out of compliance will require monthly re- inspections,
reports to the Regional Board within 24 hours, monetary sanctions, and re-
inspections at least once a month. When the business meets standards, they go
on "probation" and have visits once every four months for a year.
Newport Beach has about 65 industrially -zoned parcels
NPDES Item
N"inber 13, 2001
Page 13
How should Newport Beach Respond? As background, today we send the following
staff resources out in the field to do various forms of inspection for compliance:
• Code Enforcement (2 FTEs) - look for residential and business code
violations, often on a complaint basis.
• Business License Inspectors (2 FTEs) - follow -up on new businesses (to build
a database) and do "windshield" searches for mobile businesses and
contractors who may be operating in the city without a license.
• Building Inspectors (11 FTEs) — visit construction sites when called for
scheduled appointments. May "red tag" projects without building permits.
Inspect to see that building is constructed according to plans and that the
contractor complies with the City's grading and erosion control policies.
• Harbor Inspectors (1.5 FTEs) - look for violations of the Harbor Policy, some
water quality violations on the water.
• Fire Inspectors (2 FTEs plus station personnel) - visit all city businesses once
every three years. Visit businesses with special permits, sprinklers annually.
Look for Fire Code violations and safety issues. Typically unannounced.
• Refuse Inspector (classified as a Management Assistant) (1 FTE) - visit
construction, residential, and business sites to see that refuse containers are
covered, that only bins and roll -offs from franchised haulers are being used,
that products are being recycled, more.
The November 5, 2001 version of the Permit significantly softened inspection
requirements. Under the 11 -5 version, we may not have to increase many
construction site inspections except for sites in Cameo Shores or the last few
homes in CDM's Buck Gully. Few projects in Newport Beach will be 5 acres or
more. We will, however, have to ensure that our Building Inspectors visit each
medium- and low- priority construction site twice or once during the wet season
(regardless of where the project is in the construction process). As to commercial
facility and industrial facility inspections, Newport Beach is not home to many of
the listed businesses nor of industrial facilities.
This section of the November 5, 2001 Permit requires more analysis as to how we
will be able to comply with the inspection program, but is a significant enough
improvement over the September 12, 2001 language that I don't recommend
advocating any changes to these sections of the Permit.
What's Next? This report reflects the November 5, 2001 version of the Regional
Board's formal Tentative Order (the nearly- approved Permit). November 19,
2001 is the deadline for written comments about the Tentative Order. The Board
anticipates adopting the Order at its December 19, 2001 hearing in Santa Ana.
The Permit takes effect upon adoption and would remain in effect unless stayed
or amended by the State Water Resources Control Board via an appeal. Most
observers expect the Santa Ana Permit to be appealed by the environmental
community and possibly by the development community.

Conclusion and Staff Recommendation. 1 believe that Newport Beach, as a
coastal city that often bears the brunt of urban runoff from a 154 - square mile
watershed area, should do the following:
A. Letter to the Regional Board. The City should correspond with the Santa Ana
Regional Board in advance of November 19, 2001 via a letter from the Mayor
stating the City's position that the Santa Ana Permit should:
1. Require measurable increases in awareness within the Public Education
section, similar to the San Diego Permit's language;
2. Require structural BMPs, including onsite treatment of runoff ( SUSMP) for
certain new development and significant redevelopment;
3. Specifically authorize cities to - at cities' discretion — prohibit excessive
runoff from residential areas and landscape irrigation flows.
4. Maintain and support the Permit's language relating to Inspections, General
Plan review and General Plan amendment;
5. After model maintenance procedures are provided to the Board, direct all
jurisdictions in the Permit area to complete once a week street sweeping
with parking enforcement along each sweeper route.
B. Citv Policies /Direction to GPUC. The Council should direct:
1. the General Plan Update Committee include the Permit's general plan
requirements in the scope of the General Plan update.
2. City staff to analyze and report back on the environmental and economic
effects of adopting a citywide SUSMP or structural BMP requirement in
advance of any similar action by the Regional Board.
PLEASE NOTE: In a review of the September 12, 2001, version of the proposed
Permit, l wrote a letter to the Regional Board that reflected an interim position on
some of the less controversial issues in the 9 -12 version of the Permit. That letter
is attached as Appendix B.
The FY 2001 -02 Capital Improvement Program (CIP) for the City appropriated
$20,000 for the City's obligations to the County of Orange as the "lead permittee"
under this Permit. Since the new Permit will involve more education programs
and more administration by the County, the new assessment to the City for its
allocated share is $36,291.14. This agenda item asks that the Council approve a
Budget Amendment (see Appendix C) appropriating another $16,291.14 to the
C1P for the NPDES program.

California Regional Water Quality Control Board, Santa Ana Region

Riverside, California 92501 -3348
YI9 FACSIMILE: 1202L781-6288
RE: Comments on Order #01 -20, NPDES No CAS618030 (September 12, 2001 Draft)
Dear Mr. Thibeault:
This letter represents some of the City of Newport Beach's comments on the September 12, 2001
Draft of Order #01 -20. Our City Council will be discussing the Order in more detail in
November, but I wanted to pass along these comments prior to the Council's formal
deliberations since today is the deadline for comment on the third draft.
Please know that the City of Newport Beach sincerely appreciates your Board's work on this
Order. We see the Order as a viable and appropriate vehicle to reduce - and hopefully
eliminate - the water quality impacts of urban runoff.
Here then, are our comments:
1 -- Fire Fighting FIows (Section III - 4(o)). The Order proposes the following language for
emergency and non - emergency fire fighting flows:
Emergency fire fighting flows need not be prohibited; however, appropriate BMPs shall be
intpleinented to fire extent practicable. BMPs must be iniplentented to reduce pollutants front non -
etnergency fire fighting flows.
To eliminate any distractions besides protecting life safety during emergency events, we
strongly urge your Board to mirror the language in the San Diego Region's proposed Order
for South Orange County, which reads:
Einergency fire fighting flows do not require BMPs and need not be prohibited. The Co- pennittees shall
collectively develop and iniplement a program ... to reduce polhu tail ts front non - emergency fire fighting
flows identified ... to be significant sources ofpollutrnits to the waters of the US.
NPDES Item
November 13, 2001
Page 17
2 - Public Education (Section XIII). We appreciate and support the 3rd Draft's inclusion of
language requiring that "the public and business education program makes a minimum of
10 million impressions per year" (XIII -3). This is an important addition to the previous draft
that, in part, helps us move from a somewhat ambiguous "target" of 100% of the population
to something more specific and measurable. The direction to include a hotline for reporting
potential violations and for improperly maintained municipal facilities is commendable, too
(XIII -4).
Because the goal of any educational program is to change behaviors in a measurable way,
we urge the Board to add a provision to Section XIII that includes language similar to the
San Diego Regions proposed Order for South Orange County, which directs that any
education component:
(1) measurably increase the knowledge of the target communities regarding MS4s, impacts of urban runoff
on receiving waters, and potential BMP solutions for the target audience; and
(2) measurably change the behavior of tlu target communities and thereby reduce pollutant releases to the
MS4s and the environment.
3 - Inspection Programs for Construction Areas and for Commercial and Industrial Sites
(Sections VIII and IX). While these programs and these requirements may be costly, we
support them. It is important to implement routine inspections watershed -wide -
inspections that serve both to educate and to investigate. While some may argue that the
current program - whereby areas are investigated and inspected based on a known water
quality problem - is sufficient, we may still be missing areas that generate impairments.
Our water quality testing efforts that identify problem areas - while in many cases the "state
of the art" - can still be woefully inadequate in consistently and continually identifying
problems across the watershed's M54 network.
4 - Municipal Facilities and Inspections (Section XFV -- 6). Newport Beach believes that
the MEP standard for catch basin inspection acid cleaning should be set at 100% of all catch
basins annually. Admittedly, Newport Beach does not meet this standard today - but it is
one that is unarguably MEP for us and we hope to aggressively move towards meeting it.
Thank you for this opportunity to comment on the September 12, 2001 Draft Order. Please
direct any questions you may have to me at 949 -644 -3002.
Sincerely,

NATURAL RESOURCES DEFENSE COUNCIL DEFEND THE BAY
October 18, 2001
VIA FACSIMILE (909) 781 -6288 and US MAIL
Mr. Gerard J. Thibeault
Executive Officer
Santa Ana Regional Water Quality Control Board
3737 Main Street, Suite 500
Riverside, CA 92501
Re: NPDES Permit for Orange County, Order No. 01 -20
( NPDES No. CAS 618030 )—Comments on September 12, 2001 Draft
and September 21, 2001 Response to Comments
Dear Mr. Thibeult:
On behalf of Defend the Bay and the Natural Resources Defense Council, we wish
to submit the following comments on the current draft of the above - referenced permit
( "Proposed Permit'). Defend the Bay is a non - profit organization dedicated to protecting
local waters including Newport Bay and the ocean. The Natural Resources Defense
Council is a national, non - profit environmental organization with over 500,000 members,
approximately 50,000 of whom reside in Southern California.
Our comments focus largely on new issues raised by the September 12, 2001 draft
of the Proposed Permit; Staff's responses to previous comments; and one of the most
fundamental problems with the Proposed Permit and associated DAMP: the failure of
these documents to comply with the Maximum Extent Practicable standard set forth in
the Clean Water Act and receiving water quality standards. We incorporate our original
July 20, 2001 comment letter ( "July comments ") as if set forth in full herein, as virtually
all of the issues raised in that letter are germane to the current draft of the Proposed
Permit.
Comments on New or Revised Sections of the Proposed Permit
We are pleased to see that Staff have improved the Proposed Permit by adding
provisions that would establish inspection protocols for construction sites (Section VIII)
and commercial facilities (Section IX). We also appreciate the fact that Staff have
required special consideration of water quality degradation in both the CEQA and general
planning processes. These are valuable programs that will make a difference in reducing
water pollution if implemented by the permittees.
Defend the Bay /NRDC Comments
October 18, 2001
Page 2
We are concerned, however, that Staff have deleted a provision that would have
required that pre - development hydrology be maintained after development (with respect
to both quality and flow components). See RWQCB Response to Comments (September
21, 200 1) at 17. There is no articulated basis for this decision, which makes the Proposed
Permit notably weaker than those issued in comparable jurisdictions (as discussed below).
Moreover, the only conceivable basis for Staff s position that no anti - degradation analysis
is required before issuance of the Proposed Permit is a provision such as this one. The
deletion of this provision implies strongly that the Proposed Permit will allow water
quality degradation. For this reason, and those previously stated in our July comments, at
minimum an anti - degradation analysis is clearly required prior to Permit issuance. As
previously stated, given the terms of the Permit, the dramatic growth patterns of the
region, and the clear connections between urbanization and water quality impairment
(see, e.g., Order No. 2001 -01, San Diego County NPDES Permit No. CAS0108758,
Findings 3, 4, and 5), no evidence supports the proposition that this Permit will preclude
degradation of water quality below those levels currently and previously attained in
Orange County.
II. Regional Board Response to Comments
We appreciate the fact that responding to comments takes time when the Regional
Board is proposing issuance of a major permit such as this one. However, the Board has
a duty to assure that its responses are substantive and, of course, actually responsive to
the points being made. See 40 C.F.R. § 25.8. In California, the Office of Administrative
Law recently interpreted the legal standard applicable to an agency's response to
comments pursuant to the Clean Water Act. Los Angeles Regional Water Quality
Control Board (adoption of Regional Board Resolution 98 -18), OAL File No. 99- 0602 -01
( "OAL Decision re Los Angeles RWQCB") (attached). OAL's opinion emphasized that
an agency must respond to all aspects of public comments. Its responses must
meaningfully engage the issue raised and cannot be conclusory. California courts also
have emphasized in other contexts that an agency's response to comments must contain a
"good faith, reasoned analysis" and "[c]onclusory statements unsupported by factual
information will not suffice." People v. County of Kem, 39 Cal. App. P 830, 841 -42
(1974) (noting special duty when comments made by experts and sister agencies); see
also Environmental Protection Information Center v. Johnson, 170 Cal. App. 3d 604, 627
(1985).
Unfortunately, in the majority of instances in which Defend the Bay and NRDC
commented about provisions of the Proposed Permit, Staff either failed to respond at all
or failed to respond in a minimally adequate fashion. In particular, but without limitation,
Staff's responses to comments addressing the adequacy of the DAMP and associated
Permit findings (Response to Comments Nos. 37; 40; 44; 47; 50; 51; 34; and 38) are
superficial and conclusory. Staff's response to a fact -based question about why drain
cleaning protocols in Orange County are lenient compared to those in Los Angeles
Defend the Bay/NRDC Comments
October 18, 2001
Page 3
County typifies the circular and conclusory tone of the Responsiveness Summary:
"What is appropriate for Los Angeles County may not be appropri ate for
Orange County. The MEP standard for Orange County should be based on
what is appropriate for Orange County."
Regional Board's Response to Comments at 13, No. 51.
Another example concerns our comment that the Santa Ana Region must assure
that it can comply with required inspection and audit frequencies for municipal
permittees. In its response, Staff argued that this comment is "not based on facts," and
Staff cited a federal EPA report as evidence that it maintains a lawful program. Id. at 10,
No. 38. In point of fact, the EPA report at issue reinforces our contention by stating that
the Regional Board has "fallen short in maintaining ... targeted audit frequency." EPA
NPDES Program Implementation Review —Final Report, Santa Ana Regional Water
Quality Control Board (April 16, 2001) at 3. In any case, Staff have not provided a
substantive response to the essential issue: will the Region meet State requirements, as
set forth in the cited formal SWRCB documents?
A third example of the generally non - responsive nature of the Responsiveness
Summary concerns our comment regarding the need to conduct an anti - degradation
analysis. Staff s reluctance to employ such a basic permitting tool is difficult to
understand. Whatever the reason for this disinclination, Staffs response does not address
the majority of the points we made, particularly, that growth patterns and urbanization
(and the recognized effects of both) are certain to increase pollutant loading during the
permit term. (This is now especially true given the deletion of the Proposed Permit
requirement that pre - development flow and pollutant loading mimic pre - development
levels, as discussed above.) Further, we are extremely surprised that Staff would assert—
without factual basis —that "the storm water monitoring results for Orange County for the
last ten years indicate no degradation of water quality resulting from discharges regulated
under this permit." Regional Board's Response to Comments at 1, No. 42. In fact,
monitoring results, as well as other studies locally and nationally, many of which are cited
in our July comments, demonstrate beyond argument that storm water runoff in Orange
County does threaten to cause or contribute to excedences of water quality standards and
does also cause or contribute to impairments, including those on the Regional Board's
Section 303(d) List. The Permits of virtually every Regional Board in California
recognize the impact of storm water runoff, notably including those Boards with
jurisdiction over Los Angeles and San Diego Counties. The notion that northern Orange
County is exempt from this state and national reality is incongruous to say the least.
Indeed, this claim contradicts the Findings and Fact Sheet that accompany the Proposed
Permit itself.
Finally, and more generally, with respect to the adequacy of the Permit and
DAMP (see id. at Comment No. 37; 40; 44 et al.), Defend the Bay and NRDC
Defend the Bay /NRDC Comments
October 18, 2001
Page 4
have raised a fundamentally significant issue and supported our perspective on the
issue with a submittal from one of the foremost experts in the country, Professor
Richard Horner. As further described below and as discussed in our July
comments, we believe that the DAMP and the Proposed Permit itself are not
designed to meet the MEP standard nor calibrated to assure that permitted
discharges do not cause or contribute to a violation of water quality standards. In
particular, the DAMP is extremely inadequate, and the Proposed Permit does not
rectify all of these inadequacies through the implementation of new requirements
(although it does go beyond the DAMP). We have identified the lack of evidence
in the record to support proposed findings regarding this issue; we have pointed
out (and also offer additional comments, below) that the DAMP itself falls below
the standards set in comparable jurisdictions; and we have provided the views of a
nationally - recognized expert. Yet, Staff deflect the issue without so much as a
substantive response nor reference to any evidence explaining why Staff believe
the Proposed Permit and DAMP comply with the MEP and receiving water
limits.
111. Failure of the Regional Board to Either Assure that the Storm Water
Management Program Complies with Legal Standards or to Remove
Language From the Proposed Permit "Approving" the Program.
As we previously stated, Defend the Bay and NRDC do not believe that there is
evidence in the record that the Proposed Permit and DAMP, taken together, will result in
a program that meets the maximum extent practicable standard or receiving water limits.
Indeed, nowhere in the DAMP, nor in the Proposed Permit, is there any real discussion
about the manner in which the MEP standard has been implemented or considered
(although the term is used a number of times).
However, the Proposed Permit refers to the fact that it requires implementation of
a program, presumably based on the Permit and DAMP, which will meet the MEP
'To the extent that Staff would assert that the Proposed Permit and the DAMP meet MEP
and water quality standard provisions because these requirements are recited in certain
provisions of the Proposed Permit, this response is circular. The Proposed Permit appears
to require compliance with the applicable MEP and water quality standard requirements,
at least in significant part, through implementation of the DAMP. We contend the
DAMP is inadequate and the Proposed Permit's substantive provisions do not make up
the difference. Hence, stating that the Proposed Permit requires legal standards to be met
is not, in the first case, at all clear given the way the Proposed Permit works. Moreover,
such an answer does not explain how these standards will be met by the Permit or DAMP.
The Office of Administrative Law confronted just this issue in the above -cited decision
where it stated that "the restatement of what is required provides no evidence [that those
requirements have been met]." OAL Decision re Los Angeles RWQCB at 7.
Defend the Bay /NRDC Comments

standard (Proposed Finding 36). It also strongly suggests that those control measures that
constitute compliance with the MEP standard and water quality standards are contained in
the DAMP (see Proposed Finding 37, referring to implementation of control measures "in
accordance with the approved DAMP "). See also Proposed Permit at 16 [Section IV.3].
So, to the extent that Staff have interpreted our previous comments to suggest that we
believe that the DAMP's inadequacies, alone, render the program to be implemented
pursuant to the Proposed Permit inadequate, staff are correct —but this is not the entire
point. Rather, we also contend that the Proposed Permit itself does not fully correct the
DAMP's flaws nor does it, and the associated administrative record, support the Regional
Board in meeting administrative decision - making requirements. These requirements
include that the Regional Board support (with reasoned analysis and evidence in the
record) its findings and contentions that the Proposed Permit and DAMP will result in a
legally adequate program to control storm water —if this is, in fact, the view of Staff and
the Board —and that these documents have been designed to be consistent with MEP and
receiving water limitation language.2
As previously stated in our July comments, the shortfalls of the Proposed Permit
and DAMP become especially obvious when the discrepancies between the Proposed
Permit and the DAMP (and its appendices), on one hand, and programs in comparable
' The State Water Resources Control Board has discussed the legal standard that applies
here, and it is similar to that which governs administrative agency actions generally.
Stinnes- Western Chemical Corporation, State Water Resources Control Board Order
( "WQ ") No. 86 -16 (1986). The State Board has defined this standard as equivalent to the
standard a reviewing court would apply under California Code of Civil Procedure Section
1094.5. Id. Abuse of discretion is established if "the respondent has not proceeded in
the manner required by law, the order or decision is not supported by the findings, or the
findings are not supported by the evidence." C.C.P. § 1094.5(b); see also hr the Matter of
the Petition of Exxon, WQ Order 85 -7 at 15 (Aug. 22, 1985). "Where it is claimed that
the findings are not supported by the evidence.... abuse of discretion is established if the
court determines that the findings are not supported by the weight of the evidence."
C.C.P. § 1094.5(c). Further, an administrative order or decision of any kind must be
accompanied by administrative findings that allow the court reviewing the order or
decision to "bridge the analytic gap between the raw evidence and ultimate decision or
order." Tonanga Association for a Scenic Community v. County of Los Angeles, 11 Cal.
3d 506, 515, 522 (1974). This requirement "serves to conduce the administrative body to
draw legally relevant sub - conclusions supportive of its ultimate decision ... to facilitate
orderly analysis and minimize the likelihood that the agency will randomly leap from
evidence to conclusions." Id. at 516. "Absent such roadsigns, a reviewing court would
be forced into unguided and resource - consuming explorations; it would have to grope
through the record to determine whether some combination of credible evidentiary items
which supported some line of factual and legal conclusions supported the ultimate order
or decision of the agency." Id. at n.15.

jurisdictions, on the other, are considered. As a matter of fact, a comparison of the Permit
and the DAMP's substantive provisions to other Southern California permits and
management plans demonstrates that the proposed Orange County storm water program,
as a whole, is consistently inferior. Over the last three months, NRDC obtained and
compared the relevant permits and related storm water management program documents
from Los Angeles (proposed NPDES Permit No. CAS004001, Regional Board Order No.
01 -XXX) ( "proposed Los Angeles County Permit "), Orange County, and San Diego
( NPDES Permit No. CAS0108758, Regional Board Order No. 200 1 -0 1) ( "San Diego
County Permit "). These documents include proposed permits, currently effective permits,
proposed management programs, currently effective management programs, and, where
applicable, baseline management programs (e.g., the April 1993 Orange County DAMP)
and all available appendices to such programs. In addition, we participated in two
conference calls with Regional Board staff and representatives of the County of Orange in
order to discuss the proposed Orange County program in some detail and respond to
questions from both parties.
Our review, key elements of which are set forth below, shows that the proposed
Orange County program fails to include numerous important program elements that are
features of municipal stormwater management programs to the north and south of Orange
County. These differences cannot be explained by any substantive factual difference
between the jurisdictions, all of which are major, urban regions in coastal Southern
California. Nor can a differing legal framework explain these shortcomings, as that
framework is identical.' Rather, the failure of the proposed Orange County program —
across not one or two but a broad range of program elements —to meet an established
standard of practice shows that the Orange County program has not been designed to
meet the Maximum Extent Practicable standard of the Clean Water Act. At the most
basic level, the implementation of specific program elements in neighboring jurisdictions
demonstrates that such elements are presumptively practicable; these elements must,
accordingly, be implemented in Orange County pursuant to the MEP standard.
Important inadequacies of the proposed Orange County program include, but are not
limited to, the following significant issues:
• Public Outreach and Education. The overall goals of the program are vaguely
described and weak: the proposed permit requires only that unspecified elements
of a (non- specific) consultant report be implemented. (Proposed Permit at 29,
section XIII, paragraph 1.) This report is so general in tone and with respect to
individual recommendations that it is impossible to conclude that it meets the
appropriate MEP standard, even if fully implemented. See Final Report:
'In any case, if the Board believes that there are substantive differences between the
jurisdictions that legally and factually justify the discrepancies in the proposed Orange
County program, it has failed to identify them, as it must.

Recommendations for Expanding the Orange County Stormwater Program's
Public and Business Outreach Program (PS Enterprises; September, 1999).
Making matters worse, the proposed permit and the DAMP (1993 version and as
updated, including appendices thereto) simply defer generally to this document,
providing little independent definition about what constitutes a suite of minimally
adequate program elements.
Where specific requirements are provided, they compare unfavorably with those
set by other Regional Boards. Consider these examples: the Proposed Permit
would require 10 million annual impressions and certain guidance materials; by
contrast, the proposed Los Angeles County Permit would require 35 million
annual impressions (more than three times the Orange County program). Further,
the proposed Los Angeles County Permit specifies the range of educational
activities that must be included in the program; directs the permittees to
implement a specific, ascertainable program; directs the permittees to educate a
minimum of 50% of all school children (K -12) every two years; requires detailed
pollutant- specific plans for constituents of concern; and also requires a plan to
assure that the plan is "demonstrably effective" in changing behavior. Compare
Proposed Permit at id.; DAMP (1993 and 2000) at Section 6.0; DAMP Appendix
L; Final Report: Recommendations for Expanding the Orange County
Stormwater Program's Public and Business Outreach Program (PS Enterprises;
September, 1999) with Proposed Los Angeles County Permit (NPDES No.
CAS004001) at Part 4, Section B (pages 27 -32). Similarly, the San Diego County
Permit, while only a second - generation permit, includes specific requirements
regarding target communities and minimum information. San Diego County
Permit at 34 -36.
• Construction Activities. Section XV ( "Municipal Construction
Projects /Activities ") and Section VIII ( "Municipal Inspections of Construction
Sites ") of the Proposed Permit deal directly with construction activities, as does
DAMP Appendix G and Appendix H. These sections fail to affirmatively require
that all sediment and other pollutants be retained on site, favoring less
comprehensive proscriptions; they further fail to require that SWPPs be reviewed
and implemented for sites between 1 and 5 acres. See DAMP (2000) at Section
8.0 (discussing Green Book); Appendix G, Section 4.0 ( "Construction Regulatory
Requirements ") ( "[d]ischarges of material other than stormwater are allowed only
when necessary for performance and completion of construction practices [and
when they do not violate water quality standards] "); Appendix H at 3
( "[o]perations shall be scheduled to minimize or avoid muddying and silting of. .
. channels, drains, and waters ") and 4 (SWPPs for projects greater than five acres).
By contrast, the proposed Los Angeles County permit requires that "[s]ediments
generated on the project site shall be retained using adequate treatment control or
structural controls." Proposed Los Angeles County Permit at 48. It further
requires that "[c]onstruction - related materials, wastes, spills, or residues shall be
Defend the Bay /NRDC Comments
October 18, 2001
Page 8
retained at the project site to avoid discharge to streets, drainage facilities,
receiving waters, or adjacent properties by wind or nmoff." Id. Moreover, for
projects as small as one acre, the proposed Los Angeles County Permit requires
submittal of a SWPP prior to the issuance of a grading permit. Id. at 49.
• New and Re- Development. While the latest draft of the Proposed Permit
includes a requirement for a SUSMP program, which is a positive step forward,
there are still three notable inadequacies in this aspect of the program. First, the
Proposed Permit makes the SUSMP, with numeric sizing criteri a, applicable only
to development projects for which tract maps have not been approved by
September 26, 2001. Proposed Permit at 28, note 4. This limitation is arbitrary
and, because of the time between tract approval and construction, may result in
the numeric sizing criteria applying to very few projects before submittal of a
model WQMP in July 2003. In this way, the Proposed Permit takes with one
hand what it gives with the other.° Second, the development program in the
Proposed Permit does not contain an express requirement to assure that flow
regimes are maintained at pre - development levels after development is complete.
This is in contrast to the proposed Los Angeles County Permit, which requires
permittees to "control post - development peak storm water runoff discharge rates,
velocities, and duration (peak flow control) in natural drainage systems (i.e.,
mimic pre - development hydrology) to prevent accelerated stream erosion and to
protect stream habitat." Proposed Los Angeles County Permit at 40. The current
San Diego County Permit also contains a similar provision. San Diego County
Permit at 17 [Section F.l.b.(2)]. Third, the Proposed Permit's SUSMP program is
not as broad in scope as that contained in the San Diego County Permit, including
with respect to the application of the program to roadways. See San Diego
County Permit at 18 [Section F. Lb.(2)(a)(ix)].
• Illegal & Illicit Connections. The Proposed Permit does not contain any
overarching performance standard directing specific, affirmative actions to
eliminate illegal and illicit connections. Instead, the Proposed Permit requires the
permittees to continue to prohibit these connections and activities "through their
ordinances, inspections, and monitoring programs." It also specifies a time frame
in which investigation and remedial action must occur once a problem activity or
connection is discovered. Proposed Permit at 19 [Section VII(1) -(4)]. Moreover,
neither the Proposed Permit nor the 1993 DAMP, or the recent update (including
Appendix J thereto), contains any express schedule of targeted actions, such as
Notably, the Regional Board confronted an analogous issue with respect to a new
construction permit earlier this year; at that time, it rejected the "tract map trigger"
because it would have opened a large loophole. A trigger related to the actual start of
construction would be more appropriate, as is the case in the San Diego County Permit.
San Diego County Permit at 15 [Section F. Lb.(2)].
Defend the Bay/NRDC Comments

inspections. Instead, these documents refer to previous requirements to perform
reconnaissance on the system and, other than a reference to inspections being
conducted during routine maintenance, include only indeterminate references that
fail to illuminate the underlying programmatic requirements. See, e.g., DAMP
(2000) at 59 [Section 10.4.1 ( "[c]ommencing in 99/00 the Permittees report on the
number of illicit connections found within their jurisdiction, the type of
connection and the resulting actions that were taken to permit or remove it ")]; see
also DAMP Appendix J at 1 [Section 2.1].5 Moreover, the Proposed Permit does
not contain any program to catalogue (and update on an ongoing basis) both
permitted and non - permitted connections to the MS4 system, a step that is a
predicate to effective management of the system and interdiction of illicit or
illegal activities. By contrast, the proposed Los Angeles Permit requires
permittees to "eliminate all illicit and illegal discharges ...... Proposed Los
Angeles Permit at 60. Further, that Permit sets forth a specific schedule of
inspections and also requires that a full database be maintained that identifies all
permitted and un- permitted connections to the storm drain system. Id. at 60 -62.
The San Diego Permit similarly contains affirmative requirements to "actively
seek and eliminate illicit discharges and connections" and "eliminate all detected
illicit discharges ... immediately." San Diego County Permit at 36 [Section F.5].
• Municipal Facilities & Activities. The Proposed Permit attempts to regulate
municipal activities through an idiosyncratic approach in which permittees appear
to perform self - audits. This program is totally inadequate. First, the standard of
performance should reiterate that permittees must prevent facilities from causing
or contributing to a nuisance or exceedence of a water quality standard, as this is
the applicable regulatory requirement as set forth in Section IV of the Proposed
Permit. Moreover, the discussion of the Public Agency Program in the DAMP
and its relevant appendices discloses only the most non - specific terms. To cite a
few representative examples: (1) with respect to litter control, the DAMP notes
that authority to control litter [DAMP at Section 5.3.1 ] exists and that reports are
made; (2) with respect to drainage facilities, inspections and cleaning occurs on an
"as needed basis" [DAMP at Section 5.3.3]; and (3) street sweeping programs are
said to be "maintained" [DAMP at Section 5.3.4]. Where the Proposed Permit is
itself more specific, as it is with respect to drain inlet cleaning, the frequencies
required pale in comparison to comparable jurisdictions. By contrast, the
proposed Los Angeles County Permit contains a substantially more detailed set of
requirements, including SWPPs for maintenance bases; baseline structural control
requirements for maintenance bases; prioritized schedules for drain inlet cleaning
(requiring some drains to be cleaned as frequently as monthly during the rainy
season and all drains at least annually); updated stenciling on catch basins within
' In this connection, the water quality monitoring program does not contain sufficiently
frequent, localized monitoring protocols that could substitute for an affirmative
inspection and reconnaissance program.

180 days of inspection; specified (as frequent as bimonthly) street sweeping; and
municipal parking lot cleaning protocols. Proposed Los Angeles County Permit at
52 -59.
Moreover, it is notable that the Environmental Performance Report reveals
minimal activity by the permittees and a surprising failure to address basic
problems that should have been resolved years ago. See Report of Waste
Discharge, Appendix 3.2, "Environmental Performance Report— Significant
Issues Action Plan & Updates (discussing construction of beans; materials storage
roofs; and clarifiers). Moreover, while most permittees report only a few
"significant' water quality issues, many of these problems have not been resolved.
A number of cities, furthermore, have failed to report anything at all. Id. at Report
of City of Costa Mesa; Report of City of Fullerton; Report of City of Fountain
Valley.
IV. Conclusion
While we appreciate the efforts of Staff in the latest draft of the Proposed Permit
to improve its effectiveness, it should be clear that the Proposed Permit and the DAMP
do not constitute an adequate program under Section 402(p) of the Clean Water Act. Just
as important, the Regional Board certainly has not met its obligation to respond to
comments; justify with reasoned analysis and facts in the record its findings; and show
that the Permit, if issued, would comply both with the MEP standard and receiving water
provisions.
The appropriate course now is to fix the DAMP and Proposed Permit by
undertaking a reasoned analysis that injects both with more robust requirements that meet
these standards. As things currently stand, however, at minimum the Proposed Permit
must be clarified to state that the DAMP constitutes a baseline program, but not one that
comports with MEP or the requirement that discharges not cause or contribute to an
exceedence of water quality standards. In this vein, we believe that Staff should:
➢ Delete references to the DAMP as "approved;"
➢ Add language to the Proposed Permit (based on similar language in the
proposed Los Angeles County Permit) as follows:
"General Requirements:
In addition to those specific controls and actions required by (1) the
terms of this Order and (2) the DAMP, each permittee shall
implement controls as are necessary to reduce the discharge of
pollutants in storm water to the maximum extent practicable and so
as to satisfy the other requirements of this Order."

Re: Tentative Order (November 5, 2001 Draft), Order No. 01 -20, NPDES No. CAS618030
Dear Mr- Thiheault:
I have reviewed the Tentative Order, following up my earlier reviews of the preceding drag the
Draft Drainage Area Maintenance Plan (DAMP), and your staffs September 21, 2001 response to
comments. In evaluating these documents I applied the experience of ray 24 years of work in the
urban staTmwater management field and 11 additional years of engineering practice. During this
period I have performed research, taught, and offered consulting services on all aspens of the
subject, including investigating the sources of pollutants and other causes of aquatic ecological
damage, impacts an organisms in waters receiving urban stormwater drainage, and the full range of
methods of avoiding or reducing, these impacts.
I have helped to develop stormwater management programs in Washington State, California, and
British Columbia and studied such programs around the nation. I was one of four principal
participants in a U.S. Environmental Protection Agency - sponsored assessment of 32 state, regional,
and local programs spread among 14 states in arid, semi -arid, and humid areas of the West and
Southwest, as well as the Midwest, Northeast, and Southeast This evaluation led to the 1997
publication of `Institutional Aspects of Urban Runoff Managcment. A Guide for Program
Development and Implementation" (subtitled "A Comprehensive Review of the Institutional
Framework of Successful Urban Runoff Management Programs"). My background includes eight
years of work in Southern California, where I have been a federal court- appointed oversees of
stormwater program development and implementation at the city and county level and for two
Caltrans districts. I was directly involved in the process of developing The 13 volumes of Los
Angeles County's Stormwater Program Implementation Manual, working under the terms of a
settlement agreement in &decal court as the plaintiffs' technical representative. My role was to
provide quality- control review of multiple drafts of each volume and contribute to bringing the
Program and all of its elements to an adequate level.
I have formed my opinions of the draft stormwater permit and supporting materials for Orange
County based on my entire experience in the scientific, technical, and programmatic aspens of
urban stormwater management programs. My assessment now, as it has been after my earlier

reviews, is that the documents and the program they represent are wholly inadequate to stem the
diminishment of water quality and aquatic ecosystems associated with the growth of population and
its support structure in Orange County. furthermore, this foundation is generally inferior when
compared with The substance of programs in other areas of high population and growth rate, both
locations in our nationwide database and jurisdictions neighboring orange County. Falling short of
programs in place, particularly in very similar circumstances nearby. the effort proposed far Oranges
County manifestly violates the maximum extent practicable (WP) standard to which urban
stormwater management is held.
In this letter I illustrate and support my viewpoint with comparative examples representing, without
limitation, just some of the inadequacies in the Orange County draft permit and supporting
documents. The framework is inadequate, in general, in ignoring certain key program areas
entirely; in only vaguely delineating others; and in delaying implementation of certain basic
elements, already functioning for years elsewhere, until 2002, 2003, or even 2004. Comparisons
concentrate on Los Angeles County, in light of its adjacent location and sindlarity in circumst x=s_
These comparisons are based on that program's status at the time Implementation Manual
development fi»ished, about three years ago. 1Tawever, I have seen evidence that recent activities
will improve the program further. While I concentrate on the local comparisons, examples of
superior measures could be drawn from marry programs in urban areas all across the country.
New development and redevelopment:
Nationwide --Of the 32 projects surveyed. 94 parcent require retaining the pre - development
peak discharge, typically for one or more specified storm events. By the mid -1990s 72
percent were already providing guidance on the use of a great variety of source controls.
including impervious surface limitation and protection of natural landscapes- Of the city
and county programs in the database, 89 percent conduct public agency inspections of
storrawater fatalities for maimenance needs.
Los Angeles County —There is a specification to: `-Minimize the volume of post -
development storm water runoff to an amount approximately equal to an undeveloped
vegetated site ...: - A prioritization procedure identifies projects with the greatest potential
to cause environmental harm and gives associated requirements. Standard Urban
Stormwater Mrigatiou Plans (SUSMPs) are in force for specified development categories_
Treatment practices must be selected from the full suite of available structural BMPs.
Improved site design and natural system protection practices (termed "source controls" in
this program) are in use. The program presents a clear definition of redevelopment and what
it entails with respect to stormwater Furthermore, there is specific assignment of
maintenance responsibility for structural Rhes.
Orange County —There is no mandate to mimic any aspect of pre - development hydrology -
SUSMP exemption is given projects with approved tract maps as July 2003. In my
experience, sweeping exemptions of this type virtually ensure that few projects will come
under improved stormwater management for years. Consideration of improved site design
and natural system protection practices (termed `watershed protection principles and
pofidCs" in Ibis proprarn) is not required until 7111044, putting Orange County a decade

Construction sites:
Nationwide— Approval of runoff control pleas is required before issuance of building and
grading permits in 89 percent of the city and county programs surveyed. All but one of the
cities and counties oiler some form of training to contractors responsible for construction
site pollution control
Los Angeles County —The program is based on specific criteria defining small, medium,
and large projects; and all project sizes have BW requirements. These requirements rest on
the policy, "Eroded sediments and other pollutants must be retained on sire and may not be
transported from the size via sheet flaw, swales, area drains, natural drainage courses or
wind -" Medium and large projects (as small as 2 acres) have formal planning requirements.
Special provisions apply to hillside grading and construction during the wet season. Design
review and approval criteria are explicit. Inspection frequency is timed to project
Complexity. key project phases, meteorological events, and performance record, a system
that guarantees multiple inspections per year Enforcement procedures are extensively
spelled out.
Orange County —There is no specific requirement to retain sediments and other construction
residues on the site. Requirements pertain only to projects disturbing at least 5 acres. There
are no criteria or guidelines for design review and approval- Inspection frequencies will
depend on priorities assigned by permittees. Only high priority projects will have to be
inspected as frequently as once a month and lower priority ones as little as one time in the
wet season. The basis for enforcement and penalties is vague. Contractor education gets no
mention.
Existing commercial and industrial establishments:
Los Angeles County— Regulated facilities are the target of a five -year education outreach
that began in 1998_ County inspectors are given specific initial training followed by tailgate
sessions to cover new developments Facilities covered by the county's Industrial Waste
Disposal Program are inspected at least annually and usually more often. Specified facilities
not in this program are inspected either annually (including automotive repair shops, service
stations, and resraurams) or biannually.
Orange County— Educational materials are not even required to be ready until 711/02.
Inspector training is not requited until 7 /1103_ Inspection frequencies will depend on
priorities assigned by permittees. Even high priority commercial establishments need not be
inspected at all until 7/1/04, with no specified frequency thereafter (and also no specification
for lower priority commercial sites). Only high priority industries will be inspected as
frequently as once a year, and some as little as once a permit cycle.

Los Angeles Country —The program includes a host of pollution prevention programs (e.g..
for various hazardous wastes), source control BWs (e.g., for litter, animal and yard wastes,
eroding hillsides), and clean-up effons.
Orange County --The permit and other documents are espadally vague in this area, dealing
very briefly with mangaming emstmg litter collection and repotti» g and little else. Future
permirtee development of effective programs is extremely unlikely with a leek of
requirements.
Municipal facilities and activities:
$term drainage stem:
Los Angeles County —Drain inlets and catch basins are cleaned annually, prior to the wet
season and more often as needed for various reasons. Conveyances are routinely inspected
and cleaned as heeded. Wets are stenciled every three years and evaluated for legibility
intermediately. An improved drain stenciling technique was identified through testing and
scheduled for pilot -scale installation, leading, if successrW. to full -scale use.
Orange County— A permittee is to, ".., inspect and maintain at least 806/9 of its drainage
facilities on an annual basis, with 100% of the facilities included in a two -year period, using
the model maintenance procedures .." [developed by the principal perminee]. T'herc are no
standards for "model maintenance procedures," and the language does not specify that this
maintenance necessarily means cleaning out accumulated material in drain inlets, catch
basins, and other portions of drainage systems. A more "aggressive" program need not be
developed until 711104. Drain stenciling is mentioned only in connection with the vague
"model maintenance procedures."

Los Angeles County —Thc program recognizes with detailed coverage that sanitary sewer
overflows to stormwater systems are significant pollution sources. It lays out specific
inspection, maintenance, and response procedures to prevent or minimize these flows and
interdict them if they occur.

necessary legal authority to prohibit sewage discharges to storm sewers by 7 /1 103.

Orange County —As with existing residential areas and the sanitary sewer system, the permit
virtually ignores this infrastructure element, widespread in scope and an important pollutant
source, calling only for development of "model maintenance procedures.,.
Los Angeles County—County maimenance stations (ex.. bases for staff engaged in road,
storm drain, and sewer maintenance) are required to have storm water pollution prevention
plans (SWPPPs) analogous to those required of industries covered by the general NPD&S
stormwater permit. Further. they must use specified BMPs, as appropriate. The county
provides comptehensive classroom training in stormwater managemem issues and
procedures for office staff and tailgate training for outdoor workers.
Orange County - -There is no explicit memion of these facilities and self-audits appear to be
the predicate of the program.
Public education:
Los Angalas County- -The program was developed on the foundation of a well researched
five -year plan. It includes ostensive outreach to the general public. commercial
establislumettts, industries, and schools. backed by a full complement of educational
materials.
Orange County — Goals are weak and vague, and outreach methods are described in a
fashion too general to set a direction Instructional materials are only envisioned in general
categories at this point.
I urge you to upgrade the Orange County permit and overall foundation for its normwater
management program substantially in these and other ways. I would be very pleased to answer any
questions you may have and invite you to contact me.

Recommended Actions from 11- 13 -01:
1) Authorize the Mayor to issue a letter to the California Regional Water
Quality Control Board, Santa Ana Region, stating the City's position that the
Permit should:
A. Require measurable increases in awareness within the Public Education
section, similar to the San Diego Permit's language;
B. Require structural BMPs, including onsite treatment of runoff (SUSMP) for
certain new development and significant redevelopment;
C. Specifically authorize cities to - at cities' discretion — prohibit excessive runoff
from residential areas and landscape irrigation flows;
D. Maintain and support the Permit's language relating to Inspections, General
Plan review and General Plan amendment; and
E. Direct all jurisdictions in the Permit area to complete once a week street
sweeping with parking enforcement along each sweeper route.
2) Direct the General Plan Update Committee to include the proposed Permit's
requirements relating to general plans in the scope of the General Plan
Update.
3) Direct City staff to analyze and report back on the environmental and
economic effects of adopting a citywide SUSMP or structural BMP
requirement in advance of any similar action by the Regional Board.
