Fair treatment means that no group of people, including a racial, ethnic, or a socioeconomic group, should bear a disproportionate share of the negative environmental consequences resulting from industrial, municipal, and commercial operations or the execution of federal, state, local, and tribal programs and policies. Meaningful involvement means that: (1) potentially affected community residents have an appropriate opportunity to participate in decisions about a proposed activity that will affect their environment and/or health; (2) the public's contribution can influence the regulatory agency's decision; (3) the concerns of all participants involved will be considered in the decision making process; and (4) the decision makers seek out and facilitate the involvement of those potentially affected.” Source: http://www.epa.gov/compliance/environmentaljustice/ “The SCAG RTP used Census data to profile mode choice by income category, clarifying who most benefitted from farebox subsidies for bus, urban rail, and Metrolink, a commuter rail operation.” Source: http://www.fhwa.dot.gov/environment/ejustice/case/case4.htm Table 1-4.
