Note: Prior ordinance history: Ord. No. 2008-07.
This chapter shall be known as the "City of Encinitas Stormwater
Management and Discharge Control Ordinance."
(Ord. 2015-07)
The purpose of this chapter is to protect the health, safety
and welfare of the public by regulating all discharges into the stormwater
conveyance system and the Waters of the State in order to preserve
and enhance water quality for beneficial uses by:
A. Prohibiting
non-stormwater discharges to the stormwater conveyance system;
B. Eliminating
pollutants in stormwater to the maximum extent practicable, including
pollutants from both point and non-point sources;
C. Prohibiting
activities which cause, or contribute to, exceedance of state and
federal receiving water quality objectives;
D. Protecting
watercourses from disturbance and pollution.
The intent of this chapter is to use the police power of the
city to protect, enhance, and regulate water quality in a manner which
complies with all applicable laws related to water quality, including
the federal Clean Water Act, the state Porter-Cologne Water Quality
Control Act, and the California Regional Water Quality Control Board
San Diego Region Order No. R9-2013-0001 adopted on May 8, 2013, NPDES
No. CAS0109266 and any subsequent amendments, revisions, or reissuance
of the permit.
(Ord. 2015-07)
For purposes of this chapter only, the terms below have the
following meaning:
"Beneficial uses"
means uses of water necessary for the survival or well-being
of humans, plants, and wildlife. These uses of water serve to promote
the tangible and intangible economic, social, and environmental goals.
Beneficial uses of the Waters of the State that may be protected against
include, but are not limited to, domestic, municipal, agricultural
and industrial supply; power generation; recreation; aesthetic enjoyment;
navigation; and preservation and enhancement of fish, wildlife, and
other aquatic resources or preserves. Existing beneficial uses are
uses that were attained in the surface or groundwater on or after
November 28, 1975; and potential beneficial uses are uses that would
probably develop in future years through the implementation of various
control measures. Beneficial uses are equivalent to designated uses
under federal law. [California
Water Code Section 13050(f)].
"Best management practices" or "BMPs"
means schedules of activities, pollution treatment practices
or devices, prohibitions of practices, general good housekeeping practices,
pollution prevention and educational practices, operation and maintenance
procedures, and other management practices or devices to prevent or
reduce the discharge of pollutants directly or indirectly to stormwater,
receiving waters, or the stormwater conveyance system. BMPs may be
structural or non-structural. Best management practices include, but
are not limited to, site design, source control, treatment control,
natural design methods, low flow diversions to the sewer, and structures
such as infiltration basins, clarifiers, oil and grease separators,
and filters. BMPs may include any type of pollution prevention and
pollution control measure that can help to achieve compliance with
this chapter.
"BMP maintenance"
refers to the regular action taken to maintain the as-designed
performance and functionality of a permanent or temporary BMP, and
includes, but is not limited to, repairs to the BMP as necessary,
and replacement of the BMP by an equally effective or more effective
BMP at the end of its useful life.
"City"
means the City of Encinitas.
"Clean Water Act Section 303(d) Impaired Water Body" or "impaired
water body"
means an impaired water body in which water quality does
not meet applicable water quality standards and/or is not expected
to meet water quality standards, even after the application of technology
based pollution controls required by the Clean Water Act. The discharge
of urban runoff to these water bodies is significant because these
discharges can cause or contribute to violations of applicable water
quality standards.
"Discharge"
when used as a verb, means to allow pollutants to directly
or indirectly enter stormwater, or to allow stormwater or non-stormwater
to directly or indirectly enter the stormwater conveyance system or
receiving waters, from an activity or operations. When used as a noun,
"discharge" means the pollutants, stormwater and/or non-stormwater
that is discharged.
"Discharger"
means any person engaged in activities or operations, or
owning facilities, which may result in pollutants entering stormwater,
the stormwater conveyance system or receiving waters. "Dischargers"
include, but are not limited to, real and personal property owners,
occupants, tenants, lessees, contractors, developers, managers and
employees.
"Enforcement staff"
means any City employee or authorized contractor hired by
the City who is assigned to duties involving permits and other City
approvals, inspections, or enforcement related to this chapter.
"Environmentally Sensitive Areas (ESAs)"
include, but are not limited to, all Clean Water Act Section
303(d) impaired water bodies; areas designated as Areas of Special
Biological Significance by the State Water Resources Control Board
(Water Quality Control Plan for the San Diego Basin (1994) and amendments);
water bodies designated with the RARE beneficial use by the State
Water Resources Control Board (Water Quality Control Plan for the
San Diego Basin (1994) and amendments); areas designated as preserves
or their equivalent under the Multi-Species Conservation Program within
the cities and County of San Diego; and any other similar environmentally
sensitive areas which have been identified by the City. "Directly
adjacent" means situated within 200 feet of the Environmentally Sensitive
Area. "Discharging directly to" means outflow from a drainage conveyance
system that is composed entirely of flows from the subject development
or redevelopment site, and not commingled with flows from adjacent
lands.
"Groundwater"
means subsurface water that occurs beneath the water table
in soils and geologic formations that are fully saturated. Water table
is the depth or elevation at which soil pore spaces or fractures and
voids become completely saturated with water.
"Illegal connection"
means a physical connection to the stormwater conveyance
system or receiving waters, which has not been reviewed and authorized
by the City; or a permitted connection, which conveys illegal discharges.
"Illegal discharge"
is any discharge to the stormwater conveyance system that
is not composed entirely of stormwater or is not discharged in compliance
with this chapter. This includes, but is not limited to, discharges
of non-stormwater that are not exempt as defined by this chapter,
discharges of irrigation runoff to the MS4, any discharge from an
illegal connection, and any discharge that contains additional pollutants
due to the absence of a required BMP or the failure of a BMP. Discharges
that require a City permit or a RWQCB permit that has not been issued
or has not been acknowledged by the discharger to be applicable are
illegal discharges. Discharges regulated under an applicable NPDES
permit are illegal discharges for purposes of this chapter unless
compliance with all applicable permit conditions is maintained.
"Impervious surface"
means constructed or modified surfaces that cannot effectively
infiltrate rainfall such as building rooftops, pavement, sidewalks,
driveways, etc.
"Impervious surface area"
means the ground area covered or sheltered by an impervious
surface, measured in plan view, i.e., as if from directly above. For
example, the "impervious surface area" for a pitched roof is equal
to the ground area it shelters, rather than the surface area of the
roof itself.
"Maximum extent practicable" or "MEP"
refers to the standard established by Congress in Clean Water
Act Section 402(p)(3)(B)(iii) that municipal dischargers of stormwater
must meet; MEP is an acceptability standard for best management practices
based on a level of pollutant reduction that can be achieved by the
most effective set of BMPs that can be implemented and still remain
practicable; MEP generally emphasizes pollution prevention and source
control BMPs as the first line of defense in combination with treatment
methods as a backup.
"Municipal separate storm sewer system (MS4)"
(see also, "stormwater conveyance system") means a conveyance
or system of conveyances (including roads with drainage systems, municipal
streets, catch basins, curbs, gutters, ditches, man-made channels,
or storm drains): (1) owned or operated by a state, city, town, borough,
county, parish, district, association, or other public body (created
by or pursuant to state law) having jurisdiction over disposal of
sewage, industrial wastes, stormwater, or other wastes, including
special districts under state law such as a sewer district, flood
control district or drainage district, or similar entity, or an Indian
tribe or an authorized Indian tribal organization, or designated and
approved management agency under Section 208 of the CWA that discharges
to waters of the United States; (2) designated or used for collecting
or conveying stormwater; (3) which is not a combined sewer; (4) which
is not part of the publicly owned treatment works (POTW) as defined
at 40 CFR 122.26.
"MS4 permit"
refers to RWQCB Order No. R9-2013-0001, and any subsequent
amendments, revisions, or reissuance of the permit.
"Non-point source"
refers to diffuse, widespread sources of pollution. These
sources may be large or small, but are generally numerous throughout
a watershed. Non-point sources include, but are not limited to, urban,
agricultural, or industrial areas, roads, highways, construction sites,
communities served by septic systems, recreational boating activities,
timber harvesting, mining, livestock grazing, as well as physical
changes to stream channels, and habitat degradation. Non-point source
pollution can occur year round any time rainfall, snow melt, irrigation,
or any other source of water runs over land or through the ground,
picks up pollutants from these numerous, diffuse sources and deposits
them into rivers, lakes, and coastal waters or introduces them into
groundwater.
"Non-stormwater discharge"
is any discharge to the stormwater conveyance system or receiving
waters that is not composed entirely of stormwater.
"NPDES permit"
means a National Pollutant Discharge Elimination System permit
issued by the U.S. Environmental Protection Agency, the State Water
Resources Control Board ("SWRCB"), or the California Regional Water
Quality Control Board for the San Diego Region ("RWQCB").
"Permanent BMP"
means a structural, source control, or treatment control
best management practice designed to detain, retain, filter, remove
and/or prevent the release of pollutants to surface waters from development
projects and required to remain in perpetuity, after construction
of a project is completed.
"Person"
means an individual, corporation, partnership, limited liability
company, joint venture, non-profit organization, trust, association,
or governmental agency.
"Point source"
means any discernible, confined, and discrete conveyance,
including, but not limited to, any pipe, ditch, channel, tunnel, conduit,
well, discrete fissure, container, rolling stock, concentrated animal
feeding operations, landfill leachate collection systems, vessel,
or other floating craft from which pollutants are or may be discharged.
"Pollutant"
is broadly defined as any agent that may cause or contribute
to the degradation of water quality such that a condition of pollution
or contamination is created or aggravated.
"Pollution"
is the alteration of the quality of the receiving waters
to a degree that unreasonably affects the beneficial use of the receiving
waters or the facilities that serve the beneficial uses. "Pollution"
also includes contamination which creates a hazard to the public health
through poisoning or the spread of disease.
"Receiving waters"
means all waters that are "Waters of the State" within the
scope of the State
Water Code, including, but not limited to, natural
streams, creeks, rivers, reservoirs, lakes, ponds, water in vernal
pools, lagoons, estuaries, bays, the Pacific Ocean, and groundwater.
"RWQCB"
means the California Regional Water Quality Control Board
for the San Diego Region.
"Stormwater"
means runoff which originates from precipitation events.
"Stormwater" is that portion of precipitation that flows across a
surface to the storm drain system or receiving waters. Examples of
this phenomenon include: the water that flows off a building's roof
when it rains (runoff from an impervious surface); the water that
flows into streams when snow on the ground begins to melt (runoff
from a semi-pervious surface); and the water that flows from a vegetated
surface when rainfall is in excess of the rate at which it can infiltrate
into the underlying soil (runoff from a pervious surface). During
precipitation events in urban areas, rain water picks up and transports
pollutants through stormwater conveyance systems, and ultimately to
receiving waters.
"Stormwater conveyance system" (see also, "MS4")
means private and public drainage facilities within the City
of Encinitas by which stormwater may be conveyed to waters of the
United States, including, but not limited to, streets, roads, catch
basins, natural and artificial channels, natural and artificial drainage
features, aqueducts, canyons, stream beds, gullies, curbs, gutters,
ditches, and storm drains. Historic and current development makes
use of natural drainage patterns and features as conveyances for urban
runoff. Urban streams used in this manner are part of the stormwater
conveyance system regardless of whether they are natural, man-made,
or partially modified features. In these cases, the urban stream is
both a stormwater conveyance system and a receiving water.
"Structural BMP"
means a BMP that relies on either a physical condition (other
than an entirely natural and undisturbed condition), or on a constructed
or installed device to reduce or prevent pollutants in stormwater
discharges and exempt non-stormwater discharges. Constructed or enhanced
BMPs that depend on natural materials and processes (e.g., constructed
drainage swales or buffers, or constructed wetlands), that require
periodic maintenance to function as designed, are structural BMPs.
"SWRCB"
means the State Water Resources Control Board.
"Waters of the State"
means any water, surface or underground, including saline
waters within the boundaries of California. The definition of the
"Waters of the State" is broader than that for the "Waters of the
United States" in that all water in the state is considered to be
a "Waters of the State" regardless of circumstances or condition.
Under this definition, a municipal storm sewer system (MS4) is always
considered to be a "Waters of the State" (California
Water Code Section
13050(e)).
"Waters of the United States"
means water subject to the regulatory jurisdiction of the
United States under the Federal Clean Water Act and applicable case
law. In general, this includes "navigable" waters, waters tributary
to "navigable" waters, and adjacent wetlands. (40 Code of Federal
Regulations Section 122.2).
