Del Norte County Municipal Code § 15.32 Sewer System; Industrial Wastewaters

• 15.32.60 Pretreatment Of Industrial Wastewaters

There is hereby created a special fund in the office of the county auditor to be designated as the "industrial wastewater capital recovery fund." The fund is established and fees collected and disbursed in accordance with federal regulations.

(Ord. 77-42 § 712, 1977)

All domestic or sanitary wastewaters from rest rooms, showers, drinking fountains, etc., shall be kept separate from all industrial wastewaters until the industrial wastewaters have passed through any required pretreatment system or device.

(Ord. 77-42 § 709, 1977)

1. The County Service Area No. 1 ("CSA") and the City of Crescent City ("City") manage separate sanitary sewer collection systems within their service areas. Flows generated within the CSA are collected and conveyed to the City's system, and then conveyed to the City's waste water treatment plan ("WWTP").

2. The City's WWTP is subject to a National Pollutant Discharge Elimination System ("NPDES") permit under the federal Clean Water Act and the California Water Code. As a condition of that permit, the City is responsible for the performance of all pretreatment requirements contained in federal regulations, including 40 C.F.R. 403.8(f)(l), which requires the City to have the legal authority to enforce the pretreatment requirements of the Clean Water Act against industrial users. "Such authority may be contained in a statute, ordinance, or series of contracts or joint powers agreements." (40 C.F.R. 403.8(f) (l).)

3. To effectuate the requirements of the federal regulations and the conditions of the City's permit, the City's Industrial Waste Pretreatment Ordinance, Crescent City Municipal Code 13.40, as from time to time amended, is made applicable within the area of the CSA. Any violation of the requirements of said ordinance, including any permit requirement or condition, is a violation of the County Code, and subject to the same penalties and methods of enforcement as any other violation of the County Code.

4. In order to give the City the enforcement authority necessary for the City to comply with its permit, the County will enter into a joint powers agreement pursuant to Government Code §6500 et seq. under the which the City will be granted the power to administer its Industrial Pretreatment Program within the area of the CSA.

1. Applicants for a permit for industrial wastewater discharge shall complete a district application form available at the office of the manager. The district engineer may require additional information on the characteristics of the wastewater discharge beyond that required on the application form.

2. Upon receipt of all required information, the application shall be processed and upon approval be signed by the manager, and one copy returned to the applicant. When properly signed, the application form shall constitute a valid permit for industrial wastewater discharge.

3. The application shall be approved if the applicant has complied with all applicable requirements of Chapters 15.08 through 15.44, and furnished to the district all requested information, and if the district engineer determines that there is adequate capacity in the district's facilities to convey, treat and dispose of the wastewaters.

(Ord. 77-42 § 702, 1977)

If sewerage capacity is not available, the district may require the industrial wastewater discharger to restrict his discharge until sufficient capacity can be made available. When requested, the district will advise persons desiring to locate new facilities as to the areas where industrial wastewater of their proposed quantity and quality can be received by available sewerage facilities. The district may refuse service to persons locating facilities in areas where their proposed quantity or quality of industrial wastewater is unacceptable in the available treatment facility.

(Ord. 77-42 § 707, 1977)

A wastewater pretreatment system or device may be required by the district to treat flows prior to discharge to the sewer when it is necessary to restrict or prevent the discharge to the sewer of certain waste constituents not in compliance with Section 15.28.40 to distribute more equally over a longer time period any peak discharges of wastewaters or to accomplish any pretreatment result required by the district. All pretreatment systems or devices shall be approved by the district, but such approval shall not absolve the discharger of the responsibility of meeting any effluent limitation required by the district. All pretreatment systems judged by the district to require engineering design shall have plans prepared and signed by an engineer of suitable discipline licensed in the state of California.

(Ord. 77-42 § 708, 1977)

The district may change the restrictions or conditions of a permit for industrial wastewater discharge from time to time as circumstances may require. The district shall allow an industrial discharger a reasonable period of time to comply with any changes in the industrial wastewater permit required by the district.

(Ord. 77-42 § 703, 1977)

1. The manager may suspend a permit for industrial wastewater discharge for a period of not to exceed forty-five days when such suspension is necessary in order to stop a discharge which presents an imminent hazard to the public health, safety or welfare, to the local environment, or to the district's

sewerage system.

2. Any discharger notified of a suspension of his industrial wastewater permit shall immediately cease and desist the discharge of all industrial wastewater to the sewerage system. In the event of a failure of the discharger to comply voluntarily with the suspension order, the manager shall take such steps as are reasonably necessary to insure compliance.

3. The manager shall reinstate the industrial wastewater permit upon proof of satisfactory compliance with all discharge requirements of the district.

(Ord. 77-42 § 704, 1977)

1. The district may revoke a permit for industrial wastewater discharge upon a finding that the discharger has violated any provision of Chapters 15.08 through 15.44.

2. Any discharger whose industrial wastewater permit has been revoked shall immediately stop all discharge of any liquid-carried wastes covered by the permit to any public sewer. The manager may disconnect or permanently block from such public sewer the industrial connection sewer of any discharger whose permit has been revoked if such action is necessary to insure compliance with the order of revocation.

(Ord. 77-42 § 705, 1977)

1. Periodic measurements of flow rates, flow volumes, COD and suspended solids for use in determining the annual industrial wastewater treatment charge, and such measurements of other constituents believed necessary by the district engineer, shall be made by all industrial wastewater dischargers, unless specifically relieved in writing of such obligation by the district engineer.

2. All wastewater analyses shall be conducted in accordance with the appropriate procedure contained in "standard methods." If no appropriate procedure is contained therein, the standard procedure of the industry or a procedure judged satisfactory by the district engineer shall be used to measure wastewater constituents. The charges for wastewater analysis will be the responsibility of the discharger.

(Ord. 77-42 § 710, 1977)

All discharges prohibited by Chapter 15.28 are included in this chapter as prohibited industrial waste discharge.

(Ord. 77-42 § 706, 1977)

Any industrial wastewater discharger who discharges or causes the discharge of prohibited wastewaters which cause damage to district facilities, detrimental effects on treatment processes or any other damages resulting in costs to the district shall be liable to the district for all damages occasioned thereby including attorney fees.

(Ord. 77-42 § 711, 1977)
