2005 Arizona Revised Statutes - Revised Statutes §49-474.01  Additional board duties in vehicle emissions control areas; definitions

A. The board of supervisors of a county which contains any portion of area A or area B as defined in section 49-541 shall:

1. In area A, in consultation with the designated metropolitan planning organization, synchronize traffic control signals on all existing and new roadways, within the unincorporated area and at jurisdictional boundaries, which have a traffic flow exceeding fifteen thousand motor vehicles per day.

2. In area A, beginning on January 1, 2000, develop and implement plans to stabilize targeted unpaved roads, alleys and unpaved shoulders on targeted arterials. The plans shall address the performance goals, the criteria for targeting roads, alleys and arterials, a schedule for implementation, funding options and reporting requirements.

3. In area A, acquire or utilize vacuum systems or other dust removal technology to reduce the particulates attributable to conventional crack sealing operations as existing equipment is retired.

4. In area B, synchronize traffic control signals on roadways with a traffic flow exceeding fifteen thousand motor vehicles per day.

5. Implement adjusted work hours for at least eighty-five per cent of county employees in area A each year beginning October 1 and ending April 1 in order to reduce the level of carbon monoxide concentrations caused by vehicular travel.

B. The board of supervisors of a county that contains any portion of area A as defined in section 49-541 shall make and enforce ordinances consistent with section 49-588 to reduce or encourage the reduction of the commuter use of motor vehicles by employees of the county and employees whose place of employment is within area A.

C. The board of supervisors in a county that contains any portion of area A shall develop and implement a vehicle fleet plan for the purpose of encouraging and progressively increasing the use of alternative fuels and clean burning fuels in county owned vehicles operating in area A.

D. The plan shall include a timetable for increasing the use of alternative fuels and clean burning fuels in fleet vehicles either through purchase or conversion. The timetable shall reflect the following schedule and percentage of vehicles that operate on alternative fuels or clean burning fuels:

1. At least eighteen per cent of the total fleet by December 31, 1995.

2. At least twenty-five per cent of the total fleet by December 31, 1996.

3. At least fifty per cent of the total fleet by December 31, 1998.

4. At least seventy-five per cent of the total fleet by December 31, 2000 and each year thereafter.

E. The requirements of subsections C and D of this section may be waived on receipt of certification supported by evidence acceptable to the department that the county is unable to acquire or be provided equipment or refueling facilities necessary to operate vehicles using alternative fuels or clean burning fuels at a projected cost that is reasonably expected to result in net costs of no greater than ten per cent more than the net costs associated with the continued use of conventional gasoline or diesel fuels measured over the expected useful life of the equipment or facilities supplied. Applications for waivers shall be filed with the department pursuant to section 49-412. An entity that receives a waiver pursuant to this section shall retrofit fleet heavy-duty diesel vehicles with a gross vehicle weight of eight thousand five hundred pounds or more, that were manufactured in or before model year 1993 and that are the subject of the waiver with a technology that is effective at reducing particulate emissions at least twenty-five per cent or more and that has been approved by the United States environmental protection agency pursuant to the urban bus engine retrofit/rebuild program. The entity shall comply with the implementation schedule pursuant to section 49-555.

F. If the requirements of subsections C and D of this section are met by the use of clean burning fuel, vehicle equivalents under those requirements shall be calculated as follows:

1. One vehicle equivalent for every four hundred fifty gallons of neat biodiesel or two thousand two hundred fifty gallons of a diesel fuel substitute prescribed in section 1-215, paragraph 7, subdivision (b).

2. One vehicle equivalent for every five hundred thirty gallons of the fuel prescribed in section 1-215, paragraph 7, subdivision (d).

G. For the purposes of this section, "alternative fuel" and "clean burning fuel" have the same meanings prescribed in section 1-215.
