Sec. 29.144. - Wastewater discharge permits.

Wastewater analysis. When requested by the water utilities director, a user must submit

information on the nature and characteristics of its wastewater within thirty (30) calendar days of the request. The water utilities director is authorized to prepare a form for this purpose and may periodically require users to update this information.

A.

No significant industrial user shall discharge wastewater into the POTW without first obtaining an individual wastewater discharge permit from the water utilities director, except that a significant industrial user that has filed a timely application pursuant to section 29.144.3 of this article may continue to discharge for the time period specified therein.

B.

The water utilities director may require other users whose wastewater contains or may contain pollutants not normally found or in concentrations in excess of those normally found in domestic wastewater to obtain wastewater discharge permits.

C.

Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this article and subjects the wastewater discharge permittee to the sanctions set out in sections 29.150 through 29.152 of this article. Obtaining a wastewater discharge permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, and local law.

Wastewater discharge permitting: Existing connections. Any user required to obtain a wastewater

discharge permit who was discharging wastewater into the POTW prior to the effective date of this article and who wishes to continue such discharges in the future, shall, within thirty (30) calendar days after said date, apply to the water utilities director for a wastewater discharge permit as set forth in section 29.144.5 of this article, and shall not cause or allow discharges to the POTW to continue after one hundred eighty

(180) calendar days of the effective date of this article except in accordance with a wastewater discharge permit issued by the water utilities director.

Wastewater discharge permitting: New connections. Users with an existing permit may continue

to discharge to the POTW under the conditions of the existing permit. The water utilities director may require users with an existing permit to submit a new application in accordance with section 29.144.5.

Any user required to obtain a wastewater discharge permit who proposes to begin or recommence discharging into the POTW must obtain such permit prior to the beginning or recommencing of such discharge. An application for this wastewater discharge permit, in accordance with section 29.144.5 of this article, must be filed at least ninety (90) calendar days prior to the date upon which any discharge will begin or recommence.

A.

All users required to obtain a wastewater discharge permit must submit a permit application. The water utilities director may require users to submit all or some of the following information as part of a permit application.

(1)

Identifying information.

a.

The name and address of the facility, including the name of the operator and owner.

b.

Contact information, description of activities, facilities, and plant production processes on the premises.

(2)

Environmental permits. A list of any environmental control permits held by or for the facility.

(3)

Description of operations.

a.

A brief description of the nature, average rate of production, and standard industrial classifications of the operation(s) carried out by such user. This description should include a schematic process diagram that indicates points of discharge to the POTW from the regulated processes;

b.

Types of wastes generated, a list and Material Safety Data Sheets of all raw materials and chemicals used or stored at the facility that are, or could accidentally or intentionally be, discharged to the POTW;

c.

Number and type of employees, hours of operation, and proposed or actual hours of operation;

d.

Each product produced by type, amount, processes, and rate of production;

e.

Type and amount of raw materials processed (average and maximum per day);

f.

Site plans, floor plans, mechanical and plumbing plans, and details to show all incoming and outgoing plumbing connections (including incoming potable water), valves, sewers, floor drains, spill containment, pretreatment facilities, clarifiers and appurtenances by size, location, and elevation, and all points of discharge;

(4)

Time and duration of discharges.

(5)

The location for monitoring all wastes covered by the permit.

(6)

Flow measurement. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined wastestream formula set out in section 29.132.3.

(7)

Measurement of pollutants.

a.

The categorical pretreatment standards applicable to each regulated process.

b.

The results of sampling and analysis identifying the nature and concentration, and/or mass, where required by the standard or by the water utilities director, of regulated pollutants in the discharge from each regulated process.

c.

Instantaneous, daily maximum, and long-term average concentrations, or mass, where required, shall be reported.

The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in section 29.146.9 of this article. Where the standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the water utilities director or the applicable standards to determine compliance with the standard.

d.

Sampling must be performed in accordance with procedures set out in section 29.146.10 of this article.

(8)

Any requests for a monitoring waiver (or a renewal of an approved monitoring waiver) for a pollutant neither present nor expected to be present in the discharge based on section 29.146.4B.

(9)

Any other information as may be deemed necessary by the water utilities director to evaluate the wastewater discharge permit application.

B.

Incomplete or inaccurate applications will not be processed and will be returned to the user for revision.

A.

All wastewater discharge permit applications and user reports must be signed by an authorized representative of the user and contain the certification statement in section 29.146.13A.

B.

If the designation of an authorized representative is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new written authorization satisfying the requirements of this section must be submitted to the water utilities director prior to or together with any reports to be signed by an authorized representative.

C.

A facility determined to be a non-significant categorical industrial user by the water utilities director must annually submit the signed certification statement in section 29.146.13B.

Wastewater discharge permit decisions. The water utilities director will evaluate the data

furnished by the user and may require additional information. Within thirty (30) business days of receipt of a completed wastewater discharge permit application, the water utilities director will determine whether or not to issue a wastewater discharge permit. The water utilities director may deny any application for a wastewater discharge permit.

Special user discharge permit. The water utilities director may, on a case-by-case basis, allow

groundwater to discharge to the city's sanitary sewer system. Any approved user that discharges groundwater is required to obtain a special user discharge permit (SUDP). A SUDP may be granted when no alternative method of disposal is reasonably available, and the discharge is necessary to mitigate an environmental risk or health and safety hazard or to protect the beneficial reuse of wastewater byproducts.
