Industrial users subject to coverage under the Mercury Source Control Program shall comply with BMPs and treatment requirements contained in the Mercury Source Control Policies and Procedures Manual. In addition, dental dischargers shall comply with the BMPs and treatment requirements contained in the Mercury Source Control Policies and Procedures Manual and the Dental Amalgam Pretreatment Standards found in 40 CFR Part 441.
C. In order to assure compliance with the POTW CDPS permits, local limits, and the MAHL; and to prevent pass-through or otherwise protect the wastewater system, the Chief Executive Officer may modify the Mercury Source Control Policies and Procedures Manual in accordance with subsection 12.1.110B of this chapter, to require more restrictive treatment requirements or BMPs, to impose numeric limits, to require discharge monitoring, and/or other conditions determined necessary by the Chief Executive Officer. Alternatively, the Chief Executive Officer may revoke coverage under the Mercury Source Control Program and may issue an individual control mechanism or discharge permit.
D. If an industrial user exceeds the local limit for mercury, is not in compliance with the requirements contained in the Mercury Source Control Program, or otherwise is designated by the Chief Executive Officer as a significant industrial user, the Chief Executive Officer shall revoke coverage under the Mercury Source Control Program. The Chief Executive Officer may require a discharge permit or may issue an individual control mechanism. Remedies for noncompliance shall be in accordance with part 12 of this article. (Ord. 06-195; Ord. 10-82; Ord. 18-42; Ord. 19-34)
A. The Chief Executive Officer may develop BMPs to implement the prohibitions of section 12.5.702 of this part and the local limits of subsection 12.5.703B of this part. BMPs shall be considered pretreatment standards and local limits for purposes of this article and section 307(d) of the Act. Additionally, BMPs may be categorical pretreatment standards, established by the EPA.
B. The Chief Executive Officer may develop general BMPs that are applicable to categories of industrial users, categories of activities or geographic areas. Adoption of general BMPs shall be in accord with subsection 12.1.110B of this chapter.
C. Elements of a BMP may include, but are not limited to:
1. Installation of treatment.
2. Requirements for or prohibitions on certain practices or discharges.
3. Requirements for the operation and maintenance of treatment equipment.
4. Time frames associated with key activities.
5. Procedures for compliance certification, reporting and records retention.
6. Provisions for reopening and revoking BMPs.
D. Any industrial user may be required to comply with BMPs. BMPs may be incorporated in categorical pretreatment standards, discharge permits, control mechanisms, and orders. (Ord. 06-195; Ord. 10-82; Ord. 18-42; Ord. 19-34)

In addition to the Chief Executive Officer's authority to reduce, prevent or eliminate discharges through enforcement of discharge limitations and prohibitions, the Chief Executive Officer shall have the following authorities:
A. Endangerment To Health Or Welfare Of The Community: The Chief Executive Officer, after informal notice to the affected discharger, may immediately and effectively reduce, halt or prevent any discharge of pollutants into any natural waterway, surface drainage within the City, any area under jurisdiction of the City, wastewater collection system of the City or any wastewater system tributary thereto, by any means available to the Chief Executive Officer, including physical disconnection from the wastewater system, whenever it reasonably appears that the discharge presents an imminent endangerment to the health or welfare of individual persons or the community.
B. Endangerment To Environment Or The POTW: The Chief Executive Officer, after written order to the discharger, may reduce, halt or prevent any discharge of pollutants into any natural waterway, surface drainage within the City, any area under jurisdiction of the City, wastewater collection system of the City or any wastewater system tributary thereto, by any means available to the Chief Executive Officer, including physical disconnection from the wastewater system, whenever the discharge presents or may present an endangerment to the environment or threatens to interfere with the operation of the POTW. (See also subsection 12.5.1203B of this article.)
C. Reducing, Halting Or Preventing Discharges: The discharges referred to above may be reduced, halted or prevented without regard to the compliance of the discharge with other provisions of this article. (Ord. 98-173; Ord. 99-162; Ord. 01-42; Ord. 10-82; Ord. 18-42)
