II. An transparent window shall be available.
III. The electricity meters shall be sealed with lead sealing by a competent authority or electric power company; the seal shall be confirmed by the competent authority and shall not be destroyed.
IV. The source and destination of incoming and outgoing circuits shall be marked explicitly.

The competent authority shall be informed within one week after the maintenance or replacement.
In case no independent and exclusive electricity meters can be set up for wastewater or sewage treatment/pre-treatment facilities, the facilities that have automatic control, measurement, and recording functions may be used to measure and record the consumption of electricity after being approved by the competent authority.

Where the wastewater or sewage treatment/pre-treatment facilities of an enterprise or sewage system break down for more than 24 hours, the wastewater or sewage that cannot be treated shall be stored appropriately and no discharge is allowed. Where it takes more than 30 days for repair, production of wastewater or sewage shall be suspended.
The enterprise or sewage system shall record the failure time, name of the facilities, reason for the failure, volume of the produced wastewater or sewage and its collection status, repair method and progress; the record shall be retained as a reference for three years.

Enterprises or sewage systems may entrust commissioned operators to operate wastewater or sewage treatment/pre-treatment facilities.
Enterprises or sewage systems may not entrust the commissioned operator who operated for other enterprises or sewage systems and, during the commissioned operation, caused such other enterprises or sewage systems to meet one of the following requirements in the most recent year to operate wastewater or sewage treatment/pre-treatment facilities:
I. The competent authority discovers that the discharge was rerouted.
II. A large quantity of pollutants were discharged and the competent authority found that they seriously impacted the quality of nearby water bodies.
III. The discharged wastewater or sewage contained substances harmful to the health as announced under this Act and the competent authority found that they might affect the public health.
IV. The competent authority imposed a punishment by ordering suspension of work or business.
For the enterprise or sewage system that shall designate personnel responsible for treatment of wastewater, the commissioned operator that such enterprise or sewage system entrusts shall be qualified to the level same as the designated wastewater treatment personnel. For the enterprise or sewage system that shall designate a unit responsible for treatment of wastewater or sewage, the commissioned operator that such enterprise or sewage system entrusts shall be qualified to the level same as the designated wastewater treatment personnel of Class A.
Enterprises or sewage systems shall make a record available at the site showing the arrival and leaving times of the commissioned operator and the operation and maintenance status; the signature needs to be affixed to the record for confirmation purpose. The record shall be retained as a reference for three years.
