Question

noise pollution
laws and regulations
the environmental protection agency (epa) once managed federal noise control through the office of noise abatement and control (onac). however, funding for onac stopped after 1981, shifting noise pollution control to state and local governments. responsibility for noise pollution control now falls mainly on states and local governments.
noise pollution is often not treated as seriously as other environmental problems. many cities have rules to manage loud motorcycles or blaring car stereos, but enforcement can be difficult. despite its lower - profile, noise pollution remains a genuine environmental threat.
what is the key challenge in enforcing noise pollution regulations in many cities?
inconsistent enforcement due to other priorities
lack of public awareness
zero urban transportation related noise
inability to recognize noise pollution

Explanation:

Noise pollution regulations often take a back - seat to other environmental concerns. This leads to inconsistent enforcement as cities prioritize other issues. Public awareness is a factor but not the key challenge. Zero urban transportation - related noise is an unrealistic goal and not a challenge to enforcement. The ability to recognize noise pollution is not the main obstacle to enforcement.

Answer:

inconsistent enforcement due to other priorities
