Specific effluent limits shall not be developed and enforced without individual notice to persons or groups who have requested such notice and an opportunity to respond.

H. No user shall ever increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with a discharge limitation unless authorized by an applicable pretreatment standard or requirement, or in any other pollutant-specific limitation developed by the city or state. (Comment: Dilution may be an acceptable means of complying with some of the prohibitions set forth in Section 13.76.080(B)(2), e.g. the pH prohibition.)

I. Any wastewater containing pollutants, substances or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.

J. When the city determines that a user(s) is contributing to the POTW, any of the above enumerated substances in such amounts as to interfere with the operation of the POTW, the city shall:

1. Advise the user(s) of the impact of the contribution on the POTW;

2. Develop effluent limitation(s) for such user(s) to correct the interference with the POTW.

(Ord. 627A § 1 (part), 1994: Ord. 318 § 1(B) (part), 1974)

(Ord. No. 778, 4-17-2012)

A. Grease, oil and sand interceptors shall be provided when, in the opinion of the department, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any inflammable wastes, sand and other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units.

B. All grease, oil and sand interceptors shall be constructed in accordance with the uniform mechanical and plumbing codes and other standards adopted by the city. All interceptors shall be of a type and capacity approved by the department and shall be located as to be readily and easily accessible for cleaning and inspection.

C. Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation.

D. The city may inspect the facilities of any user to ascertain whether the purposes of this chapter and Chapters 13.80 to 13.88 are being met and all requirements are being complied with. All such inspections shall be carried out in accordance with Chapter 1.12 of this code. Sampling points shall be so located that they are safe and accessible to city inspectors at any reasonable time.

E. All interceptor facilities shall be subject to a minimum yearly inspection but maintenance and operating conditions may dictate a more frequent schedule. Inspection and monitoring fees chargeable under this section shall be the responsibility of the owner and shall be paid to the city on the basis of actual cost, plus fifteen percent, for all services furnished by the city. The city shall furnish a statement of all charges for services performed and payment of such charges shall be completed within ten days after receipt thereof.

F. No person shall discharge wastewater:

1. Containing more than forty mg/L of oil or grease of animal or vegetable origin;

2. Containing more than seventy mg/L of oil or grease of mineral or petroleum origin.

(Ord. 627A § 1 (part), 1994: Ord. 318 § 1(B) (part), 1974)

A. Limitations on Point of Discharge. No person shall discharge any substances directly into a manhole or other opening in a community sewer other than through an approved building sewer, unless, upon written application by the user and payment of the applicable user charges and fees, the city issues a permit for such direct discharges.

B. Holding Tank Waste. A user proposing to discharge holding tank waste into a community sewer must secure a permit. Unless allowed by the city under the terms and conditions of the permit, a separate permit must be secured for each separate discharge. This permit will state the specific location of discharge, the time of day the discharge is to occur, the volume of the discharge and the waste-water constituents and characteristics. If a permit is granted for discharge of such waste into a community sewer, the user shall pay the applicable user charges and fees and shall meet such other conditions as required by the city. This subsection shall apply to trailer disposal facilities.

C. Limitations on the Users of Garbage Grinders.

1. Waste from garbage grinders shall not be discharged into a sanitary sewer except:

a. Wastes generated in preparation of food normally consumed on the premises; or

b. Where the user has obtained a permit for that specific use from the city, and agrees to undertake whatever self-monitoring is required to enable the city to equitably determine the user charges based on the waste constituents and characteristics.

2. Such grinders must shred the waste to a degree that all particles will be carried freely under normal flow conditions prevailing in the community sewer. Garbage grinders shall not be used for grinding plastic, paper products, inert materials or garden refuse without written permission from the city.

D. Limitations on Radioactive Wastes. No person shall discharge or cause to be discharged any radioactive waste into a community sewer except:

1. When the person is authorized to use radioactive materials by the State Department of Health or other governmental agency empowered to regulate the use of radioactive materials;

2. When the waste is discharged in strict conformity with current California Radiation Control Regulations (California Administrative Code, Title 17), and the Atomic Energy Commission regulations and recommendations for safe disposal; and

3. When the person is in compliance with all rules and regulations of all other applicable regulatory agencies.

E. Pretreatment Standards. Pretreatment requirements shall be in accordance with sewer standards promulgated by the department of public works.

F. Monitoring Facilities.

1. The city may require the user to construct, at his own expense, monitoring facilities to allow inspection, sampling and flow measurement of the building sewer or internal drainage systems and may also require sampling or metering equipment to be provided, installed and operated at the user's expense. The monitoring facility should normally be situated on the user's premises, but the city may, when such a location would be impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk area and located so that it will not be obstructed by landscaping or parked vehicles.

2. If the monitoring facility is inside the user's fence, there shall be accommodations to allow access for city personnel, such as a gate secured with a city lock. There shall be ample room in or near such sampling manhole(s) to allow accurate sampling and compositing of samples for analyses. The manhole(s), sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.

3. Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the city's requirements and all applicable local agency construction standards and specifications. Construction shall be completed within ninety days following written notification by the city unless a time extension is otherwise granted by the city.

G. Right of Entry. The city engineer and other duly authorized employees of the city may inspect the facilities of any user subject to the provisions of this division, to ascertain whether the purpose of this chapter and Chapters 13.80 to 13.88 are being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the city or its representative ready access at all reasonable times to all parts of the premises for the purposes of inspection or sampling or in the performance of any of their duties. The city shall have the right to set up on the user's property such devices as are necessary to conduct sampling or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with their security guards so that upon presentation of suitable identification, personnel from the city will be permitted to enter without delay for the purposes of performing their specific responsibilities.

H. Accidental Discharges. Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this division. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operation procedures to provide this protection shall be submitted to the city for review and shall be approved by the city before construction of the facility. No user who commences contribution to the POTW after the effective date of the ordinance codified in this division shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the city. Review and approval of such plans and operation procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this division. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.

1. Written Notice. Within five days following an accidental discharge, the user shall submit to the department a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this division or other applicable law.

2. Notice to Employees. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall insure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.

I. Discharge Restriction Provision. Whenever deemed necessary, the department may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this division.

J. Flow Equalization. The department may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.

K. Gas Detection Equipment. Users with the potential to discharge flammable substances may be required to install and maintain, on their property and at their expense, an approved combustible gas detection meter.

(Ord. 627A § 1 (part), 1994: Ord. 318 § 1(B) (part), 1974)

A. Private Septic and Sewer Systems. No person or other entity shall install, upgrade or expand a private septic or other type of sewer system within the city limits without first having obtained approval from the city public works department together with a permit granted by the Shasta County health department. The necessary approval and permit may be granted only in those cases where (1) no public sewer is located within two hundred feet of any property line of the premises, or (2) connection to the public sewer is prohibited by law or regulation. When a permit is granted, it shall only continue to be valid as long as the private septic or sewer system does not become a health hazard and only until such time as municipal sewer services are extended to a location within two hundred feet of any property line of the premises. Whenever either of the foregoing circumstances occurs, the permit shall automatically expire and the owner of the property where such private septic or sewer system is located shall immediately be obligated, at his or her sole expense, to abandon the same and connect to the municipal sewer system after paying all applicable charges.

B. Abandonment of Existing Private Septic or Sewer Systems. Any property owner who has an existing private septic or sewer system on his or her property at the time of the enactment of the ordinance codified in this section shall not be required to abandon the same unless (1) such septic or sewer system becomes a public health hazard, or (2) the owner elects to connect to the municipal sewer system. If either of the foregoing circumstances occurs, then the owner of the subject property shall immediately abandon the private septic or sewer system in the manner directed by the public works director of the city.

(Ord. 699, 2000)

Users shall provide wastewater treatment as necessary to comply with this division and shall achieve compliance with all categorical pretreatment standards, local limits and the prohibitions set out in Section 13.76.080 of this chapter within the time limitations specified by EPA, the state or the department, 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 submitted to the department for review, and shall be acceptable to the department 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 city under the provisions of this division.

(Ord. 627A § 1 (part), 1994)

A. Upon the promulgation of a Federal Categorical Pretreatment Standard for a particular industrial subcategory, the national standard, if more stringent than limitations imposed under this division for sources in that subcategory, shall immediately supersede the limitations imposed under this division. The department shall notify all affected users of the applicable reporting requirements under 40 CFR Section 403.12.

B. The categorical pretreatment standards found at 40 CFR Chapter 1, Subchapter N, Parts 405—471 are hereby incorporated:

1. Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the department may impose equivalent concentration or mass limits in accordance with 40 CFR Section 403.6(c).

2. When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the department shall impose an alternate limit using the combined waste-stream formula in 40 CFR Section 403.6(e).

3. A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR Section 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.

4. A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR Section 403.15.

(Ord. 627A § 1 (part), 1994)

Laterals and building sewers, including the portion in public rights-of-way, shall be owned and maintained by the benefitting property owner. Such laterals and building sewers shall be constructed and maintained in accordance with the city construction standards as established by the public works director. The minimum size for laterals and building sewers in the city shall be four inches. Replacement and/or repair when deemed necessary by the department shall be a responsibility of the property owner.

(Ord. 627A § 1 (part), 1994)

(Ord. No. 834, § 3, 11-17-2020)

At least once every two years, the department shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan. The department may require any user to develop, submit for approval and implement such a plan. Alternatively, the department may develop such a plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:

A. Description of discharge practices, including nonroutine batch discharges;

B. Description of stored chemicals;

C. Procedures for immediately notifying the department of any accidental or slug discharge, as required by Section 13.80.120(F) of this division; and

D. Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
