The Office of Civil Rights in United States Environmental Protection Agency (USEPA) announced on July 18, 2012 that it had closed its investigation of a Title VI complaint
filed in 1995 against DTSC. The complaint alleged that DTSC’s enforcement activities evidenced a pattern of statewide discrimination against Latino communities. USEPA concluded that “no evidence of a statewide pattern [of discrimination] was presented or discovered during [its] investigation.” The complaint alleged five (5) areas of discriminatory conduct by DTSC. In a series of letters in 1999, 2001, and 2003, USEPA had previously rejected for investigation or action all of the allegations in the complaint, except for the allegation of discriminatory enforcement. The July 18, 2012 letter found that there was an insufficient basis to warrant an investigation of this last allegation.
