  20. WORK TRIP REDUCTION PLAN
    means a plan required by Rule 1501 submitted to the Executive Officer every other year that includes employee programs that will achieve the employer's average vehicle ridership target. The plan also includes episode contingency measures which will reduce the emissions from use of motor vehicles through trip reduction and ride sharing as needed to lower the ambient concentrations of ozone, nitrogen dioxide, PM10, and carbon monoxide.
