sentences:  In November 2000, WE ACT, filed a complaint with the U.S. Department of Transportation (USDOT) claiming that bus depots were disproportionately located in minority communities in Northern Manhattan, which houses six of the eight total bus depots in Manhattan, thus elevating the health risks associated with high exposure to harmful diesel exhaust.The USDOT found that the MTA violated Title IV of the Civil Rights Act of 1964 and failed to meet the federal environmental impact analysis involving the construction, rehabilitation, and operation of bus depots and other facilities.This campaign led to the MTA's modification of bus depots and investment in clean-fuel buses, as well as increased public awareness pertaining to the dangers of fuel fumes and poor air quality.
