To protect human health and the environment, this chapter sets forth uniform requirements for liquid waste generators and liquid waste haulers operating in the City of Carrollton and enables the city to comply with all applicable State and Federal laws, including the Clean Water Act (33 United States Code § 1251 et seq.) This ordinance chapter continues, with some revisions, the liquid waste program established by the city in Ordinance No. 1751, passed on 11-15-91.
The objectives of this chapter are:
(A) 
To aid in the prevention of sanitary sewer overflows resulting from blockages and obstructions due to the accumulation of fats, oils and greases from commercial and industrial facilities;
(B) 
To promote the proper maintenance of grease traps and grit traps; and,
(C) 
To ensure the proper handling, disposal, transport and tracking of trap waste and other liquid waste.
(Ordinance 3243, adopted 8/5/2008)
The City Manager or his designated city official will administer, implement and enforce the provisions of this chapter. Any powers granted to or duties imposed in this chapter upon the City Manager may be delegated to other city personnel.
