(a) 
This article sets forth standard requirements for users of the wastewater collection system and publicly owned treatment works for the city and enables the city to comply with all applicable state and federal laws, including the Clean Water Act (33 United States Code [U.S.C.] section 1251 et seq.) and the general pretreatment regulations (title 40 of the Code of Federal Regulations [CFR] part 403). The objectives of this article are:
(1) 
To prevent the introduction of pollutants into the publicly owned treatment works that will interfere with its operation;
(2) 
To prevent the introduction of pollutants into the publicly owned treatment works that will pass through the publicly owned treatment works, inadequately treated, into receiving waters, or otherwise be incompatible with the publicly owned treatment works;
(3) 
To protect both publicly owned treatment works personnel who may be affected by wastewater and sludge in the course of their employment and the general public;
(4) 
To promote reuse and recycling of industrial wastewater and sludge from the publicly owned treatment works;
(5) 
To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the publicly owned treatment works;
(6) 
To enable the city to comply with its Texas Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the publicly owned treatment works is subject;
(7) 
To protect the waters of the state within the jurisdiction of the city from the introduction of pollutants; and
(8) 
To protect the quality of the wastewater sludge to enable its use and disposal in compliance with applicable statutes and regulations.
(b) 
This article shall apply to all users of the publicly owned treatment works. This article authorizes the issuance of individual wastewater discharge permits; provides for monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.

In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source, should be considered.
(2) 
Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of subsection (1)(A) or (B) above but otherwise alters, replaces, or adds to existing process or production equipment.
