Article IV — Use Regulation and Protective Measures

No person shall discharge, deposit, or throw, or cause, allow or permit to be discharged, into any public sewer or plumbing fixture or into any drain, manhole, culvert, catch basin, sanitary catch basin, or private sewer which connects to the sewerage system, any substance of any kind whatsoever which tends to obstruct or injure the sewerage system, or causes a nuisance, or which in any manner interferes with the proper repair or maintenance of the sewerage system, or which in any way renders it difficult for any workmen to operate or repair the sewerage system, or renders it impossible to meet the effluent or solid residues disposal requirements which may be set by the Regional Water Quality Control Board, including, but not limited to, any discharge of waste into the sewerage system which causes, threatens to cause, or is capable of causing, either alone or by interaction with other substances, any of the following:

A.

Fire or explosion;

B.

Obstruction of the flow in, or injury to, the sewerage system, or any portion thereof;

C.

Danger to the life or safety of any person;

D.

Conditions inhibiting or preventing the effective maintenance or operation of the sewerage system;

E.

Strong or offensive odor, air pollution, or any noxious, toxic, or malodorous gas or substance, or gasproducing substance;

F.

Interference with the wastewater treatment process, or excessive collection or treatment costs;

G.

Use of a share of the capacity of the sewerage system in excess of that permitted;

H.

Interference with any wastewater reclamation process which does or may operate in conjunction with the sewerage system, or any overloading or breakdown of such reclamation process, or excessive reclamation costs, or which results in any product of the treatment process which renders such reclamation process impracticable or infeasible under normal operating conditions;

I.

Detrimental environment impact, or a nuisance wherever located or a condition unacceptable to any public agency having regulatory jurisdiction over operation of the sewerage system;

J.

Discoloration, or any other adverse condition in the quality of the effluent from the sewerage system such that discharge wastewater quality requirements established by any applicable law, rule, regulation, chapter, or permit condition cannot reasonably be met by the treatment plant; or

K.

Conditions at or near the sewerage system, or any portion thereof, which cause, or may cause, the CSA or the district to be in violation of the requirements of any applicable law, rule, regulation, chapter or permit.

(Prior gen. code § 7-254.0)

All sewers shall be discharged into the sewerage system except as provided herein. Discharge shall be through a county-approved sewer connection to a service lateral unless a special permit has been issued by the director to allow direct discharge into a manhole or other part of the sewerage system.

(Prior gen. code § 7-254.1)

A.

Protection from Accidential Discharge. As required by the director, users shall provide protection from accidental discharges of prohibited materials or other wastes into the sewerage system. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user's expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the county for review and shall be approved by the county prior to construction of the facility. The review and approval of such plans and operating procedures shall in no way relieve the user of the responsibility for modifying the facility as required by the county to provide the protection necessary to meet the requirements of this chapter.

B.

Notification Required. All users shall notify the treatment plant first and then the director by telephone immediately upon accidentally discharging, or discovering the discharge of wastes in violation of this chapter so that the county and/or the district may take counter-measures to minimize damage to the sewerage system, treatment plant, treatment process and the receiving waters. The telephone notification shall be followed within fifteen (15) days of the date of occurrence by a detailed written statement, delivered to the director, describing the cause of the accidental discharge and the measures being taken to prevent similar future occurrences. Such notification shall not relieve the user of liability for any loss, cost or

expense incurred by the CSA and/or district as a result of such discharge, including without limitation, loss or damage to the sewerage system, treatment plant or treatment process and any fines imposed by any agency on the CSA on account thereof.

C.

Notice to Employees. The director shall require that notice be permanently posted on a bulletin board in the offices of each commercial user, advising such user's employees of the numbers to call in case of an accidental discharge in violation of this chapter.

(Prior gen. code § 7-254.2)

No person shall discharge, cause to be discharged, or permit to be discharged into the sewerage system any stormwater, groundwater, rainwater, street drainage, subsurface drainage, swimming pool draining, roof runoff, yard drainage, water from irrigation, water from cooling condensers, unpolluted industrial process water, water from processing or other sources which produces an unpolluted effluent satisfactory for direct discharge into the storm drains or surface waterways.

(Prior gen. code § 7-254.3)

As deemed necessary by the director, a user shall provide facilities for storage of peak flows to prevent flows beyond the capacity of the sewerage system or the user's allocation of capacity.

C.

Any gasoline, benzene, naphtha, fuel oil or other liquid, solid or gas which by reason of its nature or quantity is sufficient, or may be sufficient, to cause, either alone or by interaction with other substances, fire, explosion or injury in any other way to any person, property or the sewerage system;

D.

Any garbage, except garbage properly ground with a mechanical garbage grinder and otherwise meeting the requirements herein;

E.

Any cans, litter, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, coal tar, asphalt, cement, plastics, woods, paunch manure or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper and economical operation of the sewerage system;

F.

Any waters or wastes with a pH lower than six (6.0) or higher than nine (9.0), or having any corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel;

G.

Wastes discharged into the sewerage system from the regeneration of any water softeners of any kind or description, and chilled brine from refrigerated cooling systems whether private or commercial;

H.

Any sulfide-forming pollutant or waste which, when discharged into the sewerage system, generates sulfide concentrations in excess of 1.0 mg/l;

I.

Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions;

J.

Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewerage system for maintenance and repair; or

K.

Any waters or wastes in excess of the maximum volumes, flows and/or rates of flow prescribed in the applicable permits issued pursuant to this chapter.

(Prior gen. code § 7-254.5)

No user shall discharge any of the following toxic substances in excess of its respective concentration limit measured at the user's point of discharge into the trunk line:

In addition, no person shall discharge or cause to be discharged any wastewater containing toxic substances that are likely to endanger public health or safety, interfere with the treatment process, cause the effluent water from the treatment plant to exceed NPDES prescribed limits, or render treatment plant sludge unfit for agricultural applications.

(Prior gen. code § 7-254.6)

No septic tank, holding tank, cesspool or chemical toilet waste shall be discharged into the sewerage system.

(Prior gen. code § 7-254.7)

In addition to the limitations upon the characteristics or quantity of wastewater discharged, caused to be discharged or permitted to be discharged into the sewerage system, the director may, in connection with permit issuance or otherwise establish additional limitations on wastewater discharges upon a finding by the director that:

A.

The existing limitations may not be sufficient to protect the operation of the CSA's sewerage system, district treatment facilities, or any portion thereof, or the waste or wastewater proposed to be discharged otherwise constitutes a hazard to, or unreasonable burden upon, such operation; or

B.

The existing limitations may not be sufficient to enable the operation of the sewerage system or district treatment facilities to comply with water quality standards or effluent limitations specified in the NPDES permit or any other applicable permit.

(Prior gen. code § 7-254.8)

All measurements, tests and analyses of the characteristics of water and wastes shall be determined according to the standard methods.

(Prior gen. code § 7-254.9)

The director may require any user to install, prior to discharging into the sewerage system and at such user's expense, pretreatment or screening of such user's sewage, or such other measures as may be necessary to reduce objectionable characteristics or constituents so that the discharged sewage conforms with the requirements of this chapter. All plans and specifications relating to such pretreatment or screening shall be reviewed by the director prior to construction thereof. Approval of plans by the director shall not constitute a guarantee of pretreatment performance. All such plans and specifications shall be drawn by a registered professional engineer.

(Prior gen. code § 7-254.10)

The director may require any user to install and operate, at the user's expense, monitoring facilities to allow inspection, sampling and flow measurement in the side sewer or internal drainage systems. In the event monitoring facilities are not available on any premises, the county may monitor the sewage flow at the nearest manholes in the trunk sewer upstream and downstream of the service lateral serving the user's premises and impute any difference therein to the user's sewage.

A.

Monitoring facilities shall be situated on the user's premises.

B.

There shall be ample room in or near such monitoring facility to allow accurate sampling and composting of samples for analysis. If the monitoring facility is inside the user's fence, accommodations shall be made to allow access to the same by county personnel, such as a gate secured with a county lock.

C.

Monitoring facilities shall be provided in accordance with county design standards and specifications whether constructed on public or private property.

D.

Monitoring facilities shall be maintained at all times in a safe and proper operating condition at the full expense of the user.

E.

Monitoring facilities not installed upon initial construction of a project shall be constructed and completed within ninety (90) days following written notification by the director that such facilities are required. The director may grant a time extension upon a finding of good cause.

(Prior gen. code § 7-254.11)

The director is hereby authorized to inspect the premises of any user at all reasonable times in order to ascertain whether the provisions of this chapter or the provisions of any sewer-related permit are being complied with. Owners or occupants of premises where wastewater is created, held or discharged shall allow ready access at all reasonable times to all parts of the premises for the purposes of inspection,

sampling, monitoring, records examination, or performing any or all of the duties reasonably necessary or appropriate in carrying out or enforcing the provisions of this chapter or any permit. The director shall further have the right to install and use on the user's premises such devices as are reasonably necessary or appropriate to conduct sampling, metering, or monitoring operations or any other of the aforesaid duties. In the event a user has established security measures requiring identification and clearance prior to entry onto such user's premises, the user shall furnish and provide identification or clearance to the director so as to permit ready access by the director to the premises for the such purposes.

(Prior gen. code § 7-254.12)

Upon determination by the director that user-provided information is necessary or appropriate for the director to reasonably carry out his duties, the director may require that any person discharging, causing to be discharged, permitting to be discharged, or proposing to discharge wastewater into the sewerage system file a periodic discharge report, the cost of which shall be borne by such person.

A.

Discharge reports shall include the following:

1.

Statements of the amount of nonwastewater volumes, wastewater volumes, and rates of flow;

2.

Other information relating to the generation of waste, including wastewater constituents and characteristics of the pertinent wastewater discharge as required by the director.

B.

The director may require that discharge reports include the chemical constituents and quantity of liquid, gaseous, or solid materials stored on the premises relating to such discharge, even though such materials are not normally discharged into the sewerage system.

C.

The reports authorized and required under this section shall be filed with the director periodically and/or at such other times as the director may reasonably require.

(Prior gen. code § 7-254.13)
