Spare the Air program
From Wikipedia, the free encyclopedia
Spare the Air is a program established by the Bay Area Air Quality Management District in 1991 to combat air pollution during the summer in the San Francisco Bay Area, the season when clear skies, hot temperatures, lighter winds, and a strong temperature inversion combine and trap air pollutants near the ground. [1]
Spare the Air days are declared for days in which levels of ground-level ozone (a constituent of smog) are predicted to exceed the EPA's federal health-based standard of 84 ppb, or an air quality index over 100. [2] On a Spare the Air day, Bay Area residents are asked through radio and television announcements to reduce their driving, refrain from using gas-powered gardening equipment and curb other air polluting activities such as painting and aerosol spray can usage. People especially sensitive to smog are advised to limit their time outdoors.
[edit] Free transportation
Non-compliance with federal air pollution standards can mean losing federal money for transportation projects like wider roads, new bridges, and mass transit. To avoid these penalties, each year for a certain number of Spare the Air days that occur on non-holiday weekdays, many Bay Area transit agencies offer free rides to encourage public transportation use over cars. The number of allocated fare-free days varies from year to year, depending on available funding.
This program's subsidy drew increased media attention in 2006 when the traditional three annual free days jumped to six in response to the number of annual Spare the Air days declared being the highest in seven years. [3] [4].
In past years there have been multiple free transit Spare the Air days. However, this year there is only funding for one free transit day, June 19.[1] Bay Area bus systems will be free all day and BART, Caltrain, ACE, and all Bay Area ferries will be free until 1:00 PM.

[edit] Criticism
The program has drawn criticism for doing little to alleviate pollution. University of California, Berkeley researcher Aaron Golub calculated the cost per ton of pollution removed as a result of Spare the Air was estimated at $100,000 per ton for nitrogen oxide and hydrocarbons and $10 million per ton for particulate matter, compared to $5,000 and $20,000 per ton respectively for a pollution reduction program. [5] The cost for Spare the Air free fares is about $2 million a day, and MTC has claimed that the goal of the program is not reducing air pollution, but rather as an incentive for people to consider public transit. [6] In addition, the free fares also attract criminal elements. Crime on BART increased, with BART police blaming youths riding for free for fights, assaults, burglaries, and robberies. Calls to BART police spiked by over 100%, compared to a 10% increase in the number of passengers on the same day the previous year. [7] Because of this, BART is considering restricting free rides to only the morning commute.
Riders of ferries also complained about severe overcrowding, with ferry ridership on the Sausalito ferry experiencing a 500% increase from normal and ridership on the Larkspur ferry increasing by 150% from ridership a week previous. [8] Regular riders were turned away. However, some argue that providing free transit has helped spur the economy, by bringing people to San Francisco's shopping district that otherwise would not go.
