INDIANAPOLIS (AP) — Indiana environmental officials say the most common complaints to a hotline last year concerned open burning, open dumping and various odors.

The Indiana Department of Environmental Management said Thursday the hotline took nearly 2,000 calls in 2010, including 241 about open burning, 230 about various odors and 220 about open dumping.

Rounding out the top five most common complaints were 150 about dust and 112 about farm activities.

IDEM says it investigates all environmental complaints it receives. It says in most cases, the investigations reveal that individuals responsible for generating pollution could have easily avoided problems had they been aware of Indiana environmental rules and best management practices.
