“With this change, there was a dramatic change in air quality, reduction in sulfur dioxide, as well as fine particle pollution,” said Philadelphia Health Commissioner Thomas Farley, who directed New York’s health department at the time the ordinance passed.
Farley said only a few buildings in Philadelphia currently use these dirty oils, so the impact here will be far less.
“But these fine particles from these fuel oils tend to stay near the site … so for the people who might be exposed, this is clearly a benefit.”
