Sitting Still (or How State Anti-Idling Laws are Landing Transit and Transportation Companies in Federal Court)

TMDLs are pollutant- and water body-specific and establish the maximum amount of a pollutant a water body can receive while meeting water quality standards. Once effective, these new requirements will provide additional avenues of attack for the already active Clean Water Act citizen suit docket. …
