A series of public hearings began this week on a plan to help reduce the smog on the Houston area, and a provision to require trucks to limit idling time to five minutes will be included in the talks.

According to the Associated Press, the proposals under consideration would bring Houston and its seven surrounding counties into compliance with federal clean air standards by implementing unprecedented restrictions on highway speeds, limits on when construction crews could operate heavy equipment and when homeowners could use gas-powered lawn mowing equipment.
In December, state officials must present a plan to the Environmental Protection Agency or risk sanctions such as loss of federal highway money, limits on industrial growth or takeover of the state plan by the federal agency.
Under the plan, large trucks would be limited to five minutes of idling time and highway speed limits would be reduced to 55 mph.
