Which agency is responsible for enforcing Chapter 1 Title 15?

The correct agency responsible for enforcing Chapter 1 Title 15 is the New York City Department of Environmental Protection (NYCDEP). This agency oversees various environmental regulations, particularly those related to air and water quality within New York City. Chapter 1 Title 15 pertains specifically to regulations that impact public health and safety regarding the environment in NYC, and NYCDEP has the jurisdiction to enforce compliance within the city limits.

On the other hand, agencies like NJDEP (New Jersey Department of Environmental Protection), EPA (Environmental Protection Agency), and OSHA (Occupational Safety and Health Administration) have their designated areas of responsibility that do not specifically include enforcing Chapter 1 Title 15 in New York City. While EPA and OSHA deal with federal-level environmental protection and worker safety respectively, and NJDEP focuses on New Jersey's environmental regulations, NYCDEP is specifically empowered to implement and enforce local regulations, making it the correct choice in this context.
