9VAC5-91-180. On-road high emitter emissions standards for on-road testing through remote sensing

A. No affected motor vehicle shall exceed the on-road high emitter emissions standards for carbon monoxide (CO), hydrocarbons (HC), or nitric oxide (NO) when measured with a remote sensing device and in accordance with the inspection procedures prescribed in Part XII ( 9VAC5-91-740 et seq.). B. The on-road high emitter emissions standards for a vehicle shall be determined by multiplying the value in the Table III-B of 9VAC5-91-180 by the ASM 25-25 standard in 9VAC5-91-810 or two speed idle standard in Table III-A of 9VAC5-91-160 as is applicable for the vehicle. C. Any affected motor vehicle determined to have exceeded any on-road high emitter emissions standards when measured by a remote sensing device in accordance with the procedures of Part XII ( 9VAC5-91-740 et seq.) may be subject to an emissions inspection at an emissions inspection station in accordance with Part XII ( 9VAC5-91-740 et seq.) or a civil charge in accordance with § 46.2-1178.1 B of the Code of Virginia, or both. D. Any affected motor vehicle that exceeds the on-road high emitter emissions standards two days in any 120-day period shall be considered to have violated the emissions standards. In addition, the department may use the vehicle emissions index as a screening requirement. E. Any affected motor vehicle that exceeds the on-road high emitter emissions standards once and is also determined to have a vehicle emissions index of greater than 75 shall be considered to have violated the on-road high emitter emissions standards. F. All remote sensing measurements used to determine if a vehicle exceeds the on-road high emitter emissions standards shall be taken at valid sites under conditions at which the vehicle specific power (VSP) indicator is between 3 and 22. Standards for NO shall be corrected for VSP using the following formula: NO standard = Low Range Value + (VSP-3)/ 19 x (High Range Value - Low Range Value). Where: Low Range Value = the smaller values in Table III-B in the NO (ppm) Range column; VSP = vehicle specific power indicator; and High Range Value = the larger values in Table III-B in the NO (ppm) Range column. G. The director may adjust the values in Table III-B if it is determined that an on-road high emitter emissions standard is causing a confirmation test pass rate in excess of 20% or less than 5.0%. Such adjustments may be for specific models within each model year group based on manufacturer's emissions control technology. TABLE III‑B. TABLE III‑B.
