The city’s Metropolitan Transportation Authority says the blasting involved in creating the Second Avenue subway line has not increased air pollution.
A study commissioned by the MTA found that fine dust, sulfur dioxide and ammonia readings were above standard federal limits.
But the MTA said the levels were not elevated while the agency was doing blasting. The report stated the higher concentrations were primarily attributed to "local traffic emissions, other local sources such as commercial and residential boilers and regional or background levels."
While most New Yorkers are thrilled at the prospect of a new subway line along Second Avenue, a north-south corridor along the city’s east side, those who live in the area have complained for months about fine dust from the subway construction degrading air quality.
The monitoring program collected data on 10 pollutants at 10 stations along Second Avenue from 69th street to 87th street. Monitoring began in September and lasted a month.
Additional details from the report, done by the private firm Parsons Brinkerhoff, will be presented at a meeting later this month of the Second Avenue Subway Task Force Committee.
