Question

when a commercial landfill becomes full, what happens next, according to environmental laws? it is watered heavily to increase chemical runoff. a plastic cover, dirt, and grass seeds are added. it is left open so the smell can permeate the area. all of the trash in the entire landfill is burned.

Explanation:

When a commercial landfill is full, environmental laws require proper closure. Watering to increase runoff (harmful), leaving open (unhygienic), or burning all trash (polluting) are not compliant. Adding a plastic cover (to prevent leakage), dirt (for stability), and grass seeds (for vegetation and erosion control) is a standard closure method.

Answer:

A plastic cover, dirt, and grass seeds are added.
