[Amended 9-27-2011 by Ord. No. 235-2011]
The rates and charges to be paid to the County
for wastewater service will be the rates and charges legally in effect,
approved by and on file with the office of the County Clerk. Complete
schedules of all rates and charges legally in effect will be kept
at all times at the County's Utilities Department, where they will
be available for public inspection. Attached hereto are Rate Schedules
1 through 4, which shall be in effect with the effective date of this
chapter.
The purpose of this rule is to establish limitations
and prohibitions on the quantity and quality of wastewater which may
be lawfully discharged into the County system. Pretreatment of some
wastewater discharges will be required to achieve compliance with
this chapter. All users are required to reduce, eliminate, or otherwise
prevent polluting substances from entering their wastewater stream
by source reduction or waste minimization. The specific limitations
set forth herein are necessary to enable the County to meet requirements
contained in its permits, to protect the public health and the environment,
and to provide efficient wastewater treatment and protect the health
and safety of wastewater personnel. The County shall periodically
review said limitations to ensure that they are sufficient to meet
the goals of this chapter. The County shall recommend changes or modifications
as necessary.
A. Prohibited pollutants.
(1) Specific prohibitions. No user shall introduce into
the County system any of the following pollutants which acting alone
or in conjunction with other substances present in the wastewater
could interfere with the operation of the County system:
(a)
Pollutants which could create a fire or explosive
hazard in the County system, including, but not limited to, wastewater
streams with a closed-cup flashpoint of less than 140° F. (60°
C.) using the test methods specified in 40 CFR 261.21.
(b)
Pollutants which could cause corrosive structural
damage to the County system, but in no case, discharges with a pH
lower than 5.0 or higher than 11.5.
(c)
Solid or viscous pollutants in amounts which
could cause obstruction to the flow in the wastewater lines, or other
interference with the operation of or which could cause damage to
the County system, including grease, wax or other materials which
tend to coat and clog a sewer line or other appurtenances thereto.
(d)
Any pollutant which could cause interference
in the County system or individual unit operations, including oxygen
demanding pollutants (BOD, COD and the like), released in a discharge
at a flow rate and/or pollutant concentration which could cause interference
in the County system or individual unit operation.
(e)
Any persistent pesticides or herbicides, such
as dieldrin, aldrin, chlordane, endrin, heptachlor, toxaphene, lindane,
dioxin, benzene hexachloride (BHC), and polychlorinated biphenyls
(PCBs) or other toxic refractory organic chemicals.
(f)
Heat in amounts which will inhibit biological
activity in the County system resulting in interference, but in no
case heat in such quantities that the temperature at the treatment
works influent exceeds 40° C. (104° F). Unless a higher temperature
is allowed in the user's wastewater discharge permit, no user shall
discharge, into any public wastewater system or other appurtenance
of the County system, wastewater with a temperature exceeding 60°
C. (140° F.).
(g)
Petroleum oil, nonbiodegradable cutting oil,
or products of mineral oil origin, in amounts that will cause interference
or pass through; and in no case greater than 100 mg/l.
(h)
Pollutants which result in the presence of toxic
gases, vapors, or fumes within the County system in a quantity that
may cause acute worker health and safety problems as determined by
the County.
(i)
Trucked or hauled pollutants, except at discharge
points designated by the County.
(j)
Noxious or malodorous liquids, gases, solids,
or other wastewater which, either singly or by interaction with other
wastes, is sufficient to create a public nuisance or a hazard to life,
or to prevent entry into the wastewater system for maintenance or
repair; or pollution of receiving waters.
(k)
Wastewater which imparts color which cannot
be removed by the treatment process, such as, but not limited to,
dye wastes and vegetable tanning solutions, which subsequently imparts
color to the treatment plant's effluent, thereby violating the County's
permits.
(l)
Stormwater, surface water, groundwater, artesian
well water, roof runoff, subsurface drainage, swimming pool drainage,
condensate, deionized water, noncontact cooling water, and unpolluted
wastewater, unless specifically authorized by the County.
(m)
Sludges, screenings, or other residues from
the pretreatment of industrial wastes.
(n)
Medical wastes, except as specifically authorized
by the County in a wastewater discharge permit.
(o)
Wastewater causing, alone or in conjunction
with other sources, the treatment plant's effluent to fail a toxicity
test.
(p)
Detergents, surface-active agents, or other
substances which may cause excessive foaming in the County system.
(q)
Fats, oils, or greases of animal or vegetable
origin in concentrations greater than 300 mg/l.
(r)
Wastewater containing any radioactive wastes
or isotopes of such half-life or concentration as may exceed limit
established by the County in compliance with applicable state or federal
regulations.
(s)
A sludge discharge having a flow rate or containing
pollutant concentration that will cause inhibition, pass-through,
or sludge contamination of the County system, including, but not limited
to, the specific prohibitions defined in 40 CFR 403.5(b) to 403.12(f).
(t)
Unusual concentrations of inert suspended solids
(such as, but not limited to, fuller's earth, lime slurries, and lime
residues) or dissolved solids (such as, but not limited to, sodium
chloride and sodium sulfate).
(u)
Any pollutant which would result in a violation
of any statute, rule, regulation or ordinance of any public agency,
including discharges prohibited by the EPA.
(2) For those situations in which a County system is connected
to a municipal system, water and sanitation district, or other system
not owned by the County, the user must comply with the applicable
municipal codes, ordinances and regulations of that municipality,
the water and sanitation district or other system regarding prohibited
discharges, industrial liquid waste, and wastewater pretreatment.
B. Wastewater evaluation.
(1) The wastewater of a user shall be evaluated upon the
following criteria:
(a)
Whether the wastewater contains any element
or compound which is not adequately removed by the treatment process
and which is considered to be an environmental hazard by the County.
(b)
Whether the wastewater causes a discoloration,
foam, floating oil or grease, or any other condition in the quality
of the County treatment systems effluent such that receiving water
quality requirements established by law cannot be met.
(c)
Whether the wastewater causes conditions at
or near the County system which violate any statute, rule, or regulation
of any public agency of the state or the United States.
(d)
Whether the wastewater contains any element
or compound known to act as a lacrimator, known to cause nausea, or
known to cause severe odors constituting a public nuisance.
(e)
Whether the wastewater causes interference with
the effluent or any other product of the treatment process such as
residues, sludges or scums, rendering them unsuitable for reclamation
or reuse.
(f)
Whether the wastewater has constituents and
concentrations in excess of those listed herein.
(g)
Whether the wastewater has a higher than normal
COD (500 mg/l), BOD (250 mg/l), and/or TSS (300 mg/l) and will be
subject to an extra-strength surcharge.
(2) The County shall establish reasonable limitations
or prohibitions in the wastewater discharge permit of any user that
discharges wastewater violating any of the above criteria as shall
be reasonably necessary to achieve the purpose and policy of this
chapter.
C. National Categorical Pretreatment Standards. Certain
users are now or hereafter may become subject to National Categorical
Pretreatment Standards promulgated by the EPA specifying quantities
or concentrations of pollutants or pollutant properties which may
be discharged into the County system. All users subject to a National
Categorical Pretreatment Standard shall comply with all requirements
of such standard, and shall also comply with any limitations contained
in this chapter. Where duplication of the same pollutant exists, the
limitations which are more stringent shall prevail. Compliance with
National Categorical Pretreatment Standards for existing sources subject
to such standards or for existing sources which hereafter become subject
to such standards shall be within three years following promulgation
of the standards unless a shorter compliance time is specified in
the standards. Compliance with National Categorical Pretreatment Standards
for new sources shall be required upon promulgation of the standard.
Except where expressly authorized by an applicable National Categorical
Pretreatment Standard, no user shall increase the use of process water
or in any way attempt to dilute a discharge as a partial or complete
substitution for adequate treatment to achieve compliance with such
standard.
D. Prohibitions of drainage or groundwaters.
(1) Stormwater, groundwater, rainwater, street drainage,
rooftop drainage, basement drainage, subsurface drainage or yard drainage
shall not be discharged to the County system unless a storm sewer
or other reasonable alternative for removal of the drainage does not
exist, and then only when the discharge is approved by the County.
(2) Clean-up waters from groundwater remediation sites
or other nonstandard industrial permitted sources will normally not
be accepted into the County system. Exceptions will be considered
on a case-by-case basis where a reasonable alternative for discharge
does not exist, and then only when the discharge is approved by the
County.
(3) Any entity requesting a discharge of remediation water
or any other nonstandard industrial permitted discharge shall prepare
a detailed proposal describing the proposed discharge's characteristics,
including, but not limited to, toxicity, biotreatability, analysis
of alternatives, hazardous nature, quantity, duration, pass-through
potential, County system biological inhibition potential and any other
factors deemed appropriate by the County.
(4) The County reserves the right, if the discharge is
approved, to impose monitoring and analysis requirements on the entity
making the discharge request, which can include testing the discharge
waters and the County system influent, effluent and sludge. The County
reserves the right to deny any discharge request or to deny the continuation
of a discharge previously approved if, in the judgment of the County,
the continuance of the discharge is not desirable.
E. Septic tank or chemical toilet discharges. No user
owning vacuum or cesspool-type pumping trucks or other liquid waste
transport trucks shall discharge such waste into the County system
without prior approval from the County.
F. Other holding tank waste. No user shall discharge
any other holding tank or trap waste, including grit, grease, or hauled
industrial wastes, into the County system without prior approval from
the County.
G. Limitations on pollutant concentration. Based on the
development of technically based local discharge limitations, and
latest revisions, no user shall discharge wastewater into the wastewater
system in excess of the concentration as set forth by the County's
permit requirements for discharge or 40 CFR 403.
H. Pretreatment of wastewater.
(1) Pretreatment required. A user generating wastewater
containing waste prohibited from discharge to the County system by
this section and who desires to discharge the same to the County system
shall pretreat or otherwise dispose of the prohibited waste so as
to make the wastewater discharged to the County system conform to
the discharge standards, limits, requirements, and conditions established
in this chapter.
(2) Pretreatment facilities. The user shall provide wastewater
pretreatment as necessary to comply with this chapter and shall achieve
compliance with all categorical pretreatment standards, local limits,
and the prohibitions set out in this chapter as specified by the EPA,
the state, local limits, or the County, whichever is more stringent.
Any facilities necessary for compliance shall be provided, operated,
and maintained at the user's expense. Detailed plans describing such
facilities and operating procedures shall be prepared by an engineer
and submitted to the County for review, and shall be acceptable to
the County before such facilities are constructed. The review of such
plans and operating procedures shall in no way relieve the user from
the responsibility of modifying such facilities as necessary to produce
a discharge acceptable to the County under the provisions of this
chapter.
(3) Additional pretreatment measures.
(a)
The County may require users to restrict discharge
during peak flow periods, designate that certain wastewater be discharged
only into specific locations, relocate and/or consolidate points of
discharge, separate wastewater streams from industrial wastewater
streams, and impose such other conditions as may be necessary to protect
the County system and determine the user's compliance with the requirements
of this chapter.
(b)
The County may require any user discharging
into the County system to install and maintain, on their own property
and at their own expense, a suitable storage and flow-control facility
to ensure equalization of flow. A wastewater discharge permit, as
described in Rule 24, may be issued solely for flow equalization.
(c)
Users with the potential to discharge flammable
substances may be required to install and maintain an approved combustible
gas detection meter.
I. Oil and grease discharge limitations. The County shall
monitor wastewater discharge permit holders, automotive shops, vehicle
fueling stations, septic tank pumpers, commercial food processors,
oil tank firms and transporters, and others as appropriate. Existing
sources must maintain their traps and separation-treatment systems
to ensure that grease and oil do not enter the County system. Dischargers
shall be subject to monitoring, inspection, reporting and other requirements
as determined by the County in its discretion. These dischargers may
not be required by the County to apply for wastewater discharge permits
unless the County determines in its discretion that they are a significant
source of prohibited pollutants, toxic pollutants in toxic amounts,
extra-strength discharges, or are otherwise controlled by federal
regulations. Dischargers not in compliance shall also be subject to
operation and maintenance costs necessitated by the oil and grease
problem until the problem is corrected.
J. Surcharges.
(1) A surcharge will be assessed against any user who
discharges wastewater which is of greater strength than normal, or
of greater strength than allowed by permit, if applicable. Normal
untreated wastewater is defined as:
(a)
Chemical oxygen demand (COD) less than or equal
to 500 mg/l; or
(b)
Biochemical oxygen demand (BOD) less than or
equal to 250 mg/l; and
(c)
Total suspended solids (TSS) less than or equal
to 300 mg/l.
(2) Users with discharge exceeding the parameters defined
above for normal untreated wastewater may be assessed a monthly surcharge,
which shall be computed as provided for in Rate Schedule 3.
K. Pretreatment charges. The County may adopt reasonable
charges for reimbursement of costs of setting up and operating the
County pretreatment program, which may include:
(1) Charges for the wastewater discharge permit process
as described in Rule 24.
(2) Charges for monitoring, inspection, and surveillance,
including costs of sampling and analysis of user's discharge and reviewing
monitoring reports submitted by users.
(3) Charges for reviewing and responding to accidental
discharge procedures and construction.
(4) Other charges as the County may deem necessary to
carry out the requirements contained in this chapter. These charges
relate solely to the matters covered by this chapter and are separate
from all other charges, fines, and penalties chargeable by the County.
The purpose of this section is to define the
terms and conditions for a County sanitary sewer line extension to
serve an applicant or group of applicants. Applicants for subdivision
development shall refer to and comply with Chapter 300, Subdivision
of Land, as well as this chapter.
A. Application.
(1) The applicant requesting wastewater service requiring
a line extension must request such service in writing. The request
shall describe the following:
(a)
Number of new connections proposed;
(b)
Classification of proposed connections;
(c)
Wastewater flow projections; and
(d)
Property, plat, and/or subdivision details.
(2) The County Utilities Director shall review the application
and make a recommendation to the Board for Board consideration and
approval as to the availability and feasibility of providing such
service. The terms and conditions shall be set forth in a line extension
agreement to be executed by the County and the applicant.
[Amended 9-27-2011 by Ord. No. 235-2011]
B. Conditions of a line extension.
(1) The County may extend or approve the line extension
in the streets, alleys, and/or easements within the service areas
in order to permit connections by an applicant seeking wastewater
service. The extension will be made from the nearest adequately sized
wastewater line.
(2) All line extensions shall be installed to the farthest
property line of the lot or parcel to be developed or connected. All
wastewater laterals shall be connected to the gravity wastewater line
in a manner approved by the County.
(3) The size and capacity of the line extension shall
be determined by the capacity needs to meet the projected development
within the drainage area of the service. In the event the County requires
a larger line size than is required to serve the applicant's needs,
the County may absorb the difference in investment between the applicant's
required line size and the line size required by the County. The minimum
wastewater line size is eight inches' diameter. The County shall be
the sole judge of proper line sizing.
(4) All line extensions will be constructed in existing
public roads, streets, County-owned land, alleys, or easements. The
applicant shall furnish such rights-of-way as are required without
charge to the County within property owned by said applicant and shall
assist the County in securing other rights-of-way necessary to provide
service through property not owned by said applicant.
(5) The County shall review, approve and inspect all design
and construction of proposed line extensions. All line extensions
shall be in accordance with and in compliance with all applicable
technical provisions of County, state and federal laws. Where the
wastewater system is connected to a municipal system, water and sanitation
district, or other system not owned by the County, the line extension
will additionally be in accord with and will comply with applicable
municipal codes, ordinances and regulation of that municipality, the
water and sanitation district, or other system.
C. The total cost for the line extension as set forth
shall be paid by the applicant. The costs shall be subject to future
refunds to that applicant, if wastewater service is provided to a
new customer, under the following terms and conditions:
(1) Connection is within 10 years from the date of the
original line extension agreement between the County and applicant.
(2) The new customer's property abuts applicant's line
extension (other than at the end of applicant's line extension where
the new customer's line extension is to begin).
(3) The County connects the line extension for said new
customer's wastewater service to applicant's line extension.
(4) The refund amount to the applicant shall be determined
based on a front-foot basis for individual lots or on an acreage basis
for undeveloped tracts. The amount shall be calculated as a percentage
of the footage and/or acreage for the total parcels already connected
and to be connected to applicant's line extension.
(5) Refunds made under this provision shall not exceed
the amount of applicant's contribution to construction less that portion
needed to serve applicant.
D. The determination of whether the line extension for
a new customer's wastewater service should be connected to an existing
line extension shall be made by the County at its discretion based
on engineering considerations and the County's plans for the development
of its wastewater system.
E. Where extenuating circumstances exist and at the sole
option of the County, an extension may be made under a special long-term
contract, provided the contract terms are such that no adverse effects
will be imposed on the County's existing customers.
F. Special conditions which affect the furnishing of
wastewater service to an applicant such as elevation, terrain, capacity
and other conditions resulting in increased costs to the County in
providing wastewater service shall be taken into consideration by
the County, and the cost thereof shall be included in estimating the
cost of providing service.
G. In addition to the costs for the sewer line extension,
the property applicant must pay the administrative set-up charge and
the one-time charge as established in this chapter.
H. The County shall not under any condition be required
to make an extension that would be unprofitable and thereby cause
undue hardship to existing customers.
I. The provisions of this rule apply to connections to
line extensions already in existence and line extensions installed
after the effective date of this chapter.
The purpose of this section is to define the
County policy for accepting ownership and operation and maintenance
of wastewater infrastructure and facilities constructed after an approved
development or building process as outlined in Chapter 300, Subdivision
of Land, Chapter 250, Land Use and Zoning, and the building permit process.
A. All infrastructure to be transferred will be agreed
upon prior to approvals as set forth in this section. Acceptance of
the infrastructure and facilities shall be at the County's sole discretion.
B. All infrastructure to be transferred must have been constructed in accordance with Chapter 250, Land Use and Zoning, Chapter
274, Use of Rights-of-Way, Chapter 300, Subdivision of Land, this chapter, and applicable County design standards.
C. After final inspection and final certification by
the County, the developer will provide as-built drawings, hard copy
and electronic versions for the infrastructure to be transferred.
D. The developer will provide easements and title documents
to the County on forms provided by the County or approved by the County.
