Any other information which may be deemed necessary by the Airports Administrator to evaluate the permit application.

6515-3 - Permit conditions.

The industrial wastewater discharge permit shall constitute the performance specification to which each industrial user must conform in order to maintain authorization to use the County's sewerage system. Industrial wastewater discharge permits shall be expressly subject to all provisions of this ordinance, Federal Pretreatment Standards, Requirements and regulations pursuant to Section 307 et seq. of the Clean Water Act and all other regulations, user charges and fees established by the County. Permit conditions shall be uniformly enforced in accordance with this ordinance and applicable State and Federal regulations. Permit conditions may include but are not limited to the following: (Federal Pretreatment Regulations 40 CFR 403.8(f)(1)(i)-(vi)):

A.

Limits on the average and/or maximum wastewater constituent concentrations and other relevant qualitative characteristics. (See Article 13.)

B.

Mass emission discharge rates or any more stringent Federal Pretreatment Standards and user's average daily wastewater discharge for the past three years. When not available, data for a year or that which is mutually acceptable to the user and the County will be used.

C.

Limits on rate and time of discharge or requirements for flow regulations and equalization. (See Section 6512-4).

D.

Requirements for installation of inspection and sampling facilities and specifications for monitoring programs.

E.

Requirements for maintaining and submitting technical self-monitoring reports and plant records relating to industrial wastewater discharges.

F.

Compliance schedules. (See Section 6515-4).

G.

Applicable Federal Pretreatment Standards which are more stringent than local limitations. (See Article 13. and 14.).

H.

Other conditions to ensure compliance with this ordinance.

6515-4 - Compliance schedules.

A compliance schedule required as a result of an industrial user's non-compliance with applicable Federal and/or local Pretreatment Standards or Requirements, or for the installation of technology required to meet applicable Standards or Requirements, shall be based on the following:

A.

A list of the expected increments of progress in the form of dates for the commencement and completion of major events leading to consistent compliance with applicable Federal and/or local Pretreatment Standards.

B.

No increment referred to above shall exceed three months.

C.

Not later than 14 days following each date in the schedule and the final date for compliance, the industrial user shall submit a progress report to the Airports Administrator including as a minimum, whether or not the user complied with the latest increment of progress and, if not, the date on which the user expects to comply with this increment of progress, the reason for the delay, and the steps taken by the user to return to the schedule established.

6515-5 - Duration and revision of permits.

A.

Permits shall be issued for a period of one year or less. The terms and conditions of the permit may be subject to modification as limitations or requirements in Section 6514-4 and 6514-5 are modified or as a result of pretreatment standards and/or requirements promulgated pursuant to Section 307 et seq. of the Clean Water Act. The user shall be informed of the proposed changes in his permit 30 days prior to the effective date of the change. Any new conditions in the permit shall include a reasonable compliance schedule to be proposed by the industrial user and approved by the Airports Administrator. Such compliance schedule will allow the user time to modify the industrial process sufficiently to comply with the new permit changes.

B.

Permits issued to each industrial user shall be based on the user's typical discharge rate, peak discharge rate and wastewater constituents and characteristics as described in the user's permit application or through the County Manager's knowledge of the history of the user's discharge. The user is required to promptly notify the Airports Administrator of any significant changes in the user's operation that may affect his discharge rate, peak flow rate, wastewater constituents or characteristics. (Federal Pretreatment Regulations 40 CFR 403.12(j)).

6515-6 - Transfer of a permit.

Industrial wastewater discharge permits are issued to a specific user for a specific operation. A permit shall not be reassigned or transferred or sold to a new owner, new user, different premises or a new or changed operation.

6515-7 - Violation of the permit.

When the Airports Administrator determines that a specific condition and/or discharge is in violation of any provision of this ordinance or in violation of any permit condition or limitation imposed, the industrial user shall be issued a Notice of Violation (See Section 6518- 3 (A)) by the Airports Administrator which shall specify the violation or designate the deficiencies and shall specify a period of time within which the discharge shall be brought into conformity with all requirements. The period of time specified by the Airports Administrator shall be reasonably related to the character of the violation, to the quality and quantity of the discharge and to the risk imposed upon the County's sewerage system or threatened to the public health, safety and welfare. The discharger shall submit in writing, to the Airports Administrator, the following:
