– Increased speed enforcement – A formal request for greater enforcement of existing speed limits by the State Patrol and the Vail Police Department for all vehicles on I-70 through town.
– Muffler law enforcement – Increased enforcement of current state law requiring mufflers on vehicles with engine brakes, which levies a $500 fine for any truck with an engine brake but without a muffler. Ports of entry staff at Dumont and Loma will be asked to strictly enforce the law, and town officials will seek to effectively enforce the law on local roadways and job sites. Roadside safety inspectors will be asked to include a check of the muffler as part of their safety reviews on trucks.
– Inter-state cooperation – The association agrees to work with its affiliates in other states for the passage of a measure already in effect in Colorado requiring mufflers on trucks with engine brakes in order to further reduce the number of loud trucks passing through our state.
– Hike existing fines – The association and the town will explore the development of state legislation to hiking penalties for failure to maintain or alter a muffler. This legislation would apply to all vehicles.
– Noise meters – The association will seek to obtain a noise meter for the town to measure noise levels on I-70, as well as within the community.
– Establishing standards – The town will seek technical assistance from a third party in measuring noise levels and developing an enforceable maximum decibel standard.
– Evaluation – Noise tests will be conducted to evaluate the ongoing effectiveness of all mitigation efforts.
Pilot decibel-reduction project
Using the research identified above, the association and the town will jointly evaluate whether a maximum decibel standard for all vehicles passing through Vail could be developed based on noise standards established by the U.S. Environmental Protection Agency for all vehicles in the corridor.
Temporary noise barriers
Using the T-Rex noise-abatement actions in Denver as a model, the town and the association will explore the use of temporary noise barriers, such as trailers, as a 30-day experimental program to measure noise-reduction impacts before construction of any permanent barriers.
Noise wall funding
The association will work with the town to begin discussions with state and federal officials to seek funding for a phased noise-wall program.
The association agrees to pursue with the American Trucking Association a study on overall noise levels associated with trucks and measures that may be taken to mitigate such noise.
