The Bristol, CT regional trash agency is lowering the cost of bringing garbage to the waste-to-energy plant in Bristol. "That’s a nice shot in the arm," said Bristol Mayor Art Ward. The 14-town Bristol Resource Recovery Facility Operating Committee’s decision to lower its tipping fee by $1 a ton follows five consecutive years of the fee remaining the same.  For towns that use the facility, the change means a slightly lower tab for trash disposal, a welcome help for strained municipal budgets.  This is another example of a well run waste-to-energy facility benefiting the communities it was built to serve.
