The South Coast Air Quality Management District (AQMD) says the draft environmental impact report on the 710 extension is essentially useless because it didn’t account for the amount of cancerous emissions the tunnel project would cause.
The report suggests that the cancer risk of the project is 149 chances per million people exposed to pollutants. The district standard threshold is 10 chances per million. The AQMD suggests that Caltrans and Metro revise the air quality part of the EIR and contact them to start discussing applications for permits, because any controls put on air pollution from exhaust will require a permit from the AQMD.
In a response letter, the city of Alhambra says the traffic gridlock that happens at the place where the 710 currently ends at Valley Boulevard already causes a risk of cancer, and that the tunnel project would reduce that risk.
Does this report change your opinion on the 710 extension? What challenges does this present to the project? How will the city of Alhambra respond?
