Final answer:
In New York City, it is illegal to improperly dispose of grease, in order to prevent sewer blockages. Strict regulations require the use of grease traps and licensed waste disposal methods to ensure public health and infrastructure safety.
Step-by-step explanation:
In New York City, it is illegal to improperly dispose of grease. Laws regulate the disposal of grease to prevent damage to the sewer systems. While the question does not specify the exact activity being referred to, generally, it is understood that businesses, especially restaurants and food service establishments, must follow strict guidelines for the disposal of fats, oils, and grease (often abbreviated as FOG).
These substances can cause significant blockages in sewer lines if not handled properly. Establishments typically must have grease interceptors or traps and must ensure that grease is disposed of through a licensed waste hauler, not poured directly into drains or sewers. Such regulations are in place to protect infrastructures and maintain public health and safety. These types of regulations are similar in intent to laws that once banned substances like nitrogen trichloride for use in bleaching flour due to health concerns, indicating a continuity of public health initiatives spanning different substances and time periods.
