Compliance orders. When the Superintendent finds that a user has violated, or continues to violate, any provision of this chapter, an industrial user wastewater permit, any other pretreatment standard or requirement, or any other order or agreement between the City and the user, the Superintendent may issue an order to the user directing compliance within a specified time. If the user does not come into compliance within the time provided, sewer service may be discontinued. Compliance orders may also contain other requirements to address noncompliance, including, but not limited to additional self-monitoring and management practices designed to minimize the amount of pollutants discharged to the sewer. A compliance order may not extend the deadline for compliance established for a pretreatment standard or requirement, nor does a compliance order relieve the user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a bar against, or a prerequisite for, taking any other action against the user.
A. 
The Director, Superintendent, or other duly authorized City employee bearing proper credentials and identification shall be permitted to enter upon all properties for the purposes of inspection, observation, measurement, sampling and testing in accordance with the provisions of this chapter.
B. 
The Director, Superintendent, or other duly authorized City employee is empowered to obtain information concerning industrial processes or any other data which has a bearing on the kind and source of discharge to the public sewer.
C. 
Denying access to any facility to a properly identified inspector is a violation of this chapter.
While performing inspections and obtaining samples on private property, the Director, Superintendent or duly authorized City employee shall observe all safety rules applicable to the premises as established by the industrial user. The industrial user shall be held harmless for injury or death to the City employees, and the City shall indemnify the industrial user against loss or damage to its property by the City employee and against liability claims and demands for personal injury or property damage asserted against the industrial user growing out of the gauging and sampling operations, except if caused by negligence or failure of the industrial user to maintain safe and appropriate conditions.
A. 
Bypass of an industrial pretreatment system is prohibited except where the bypass is unavoidable to prevent loss of life, personal injury or severe property damage. The user shall notify the Superintendent immediately and, if possible, prior to the event of any bypass.
B. 
A notice shall be permanently posted, plainly visible to all user's personnel responsible for managing wastewater discharges, informing them of the required notification to the Superintendent of a potential bypass.
C. 
Bypasses shall not exempt the user from any fines, administrative actions or prohibitions of this chapter. All bypasses will be considered a violation of the industrial user wastewater permit.
If sampling performed by an industrial user indicates a violation, the user shall notify the Superintendent immediately on becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the Superintendent within 30 days after becoming aware of the violation. The industrial user is not required to resample if:
A. 
The City performs sampling of the industrial user at a frequency of at least once per month;
B. 
The City performs sampling of the industrial user between the time when the user performs its initial sampling and the time when the user receives the results of the sampling; or
C. 
The City performs sampling within 30 days of the user becoming aware of the violation.
