The Placer County board of supervisors finds that:
A. 
Air pollution is a major public health concern in California. The Sacramento region is currently designated as non-attainment for the one-hour federal ozone standard, as well as the more stringent state ozone standard. Air pollution can cause or aggravate lung illnesses such as acute respiratory infections, asthma, chronic bronchitis, emphysema, and lung cancer. In addition to health impacts, air pollution imposes significant economic costs and negative impacts on our quality of life (nuisance).
B. 
Exhaust from vehicles (both on- and off-road) is a substantial source of ozone precursors in the Sacramento region. Vehicle exhaust is also a source of carbon monoxide, particulate matter, toxic air contaminants, and greenhouse gases. Although new engines have become cleaner due to improved emission control technologies; the slow turn over in their inventory and the number of miles/hours these vehicles idle each year is hindering progress in improving regional air quality.
C. 
Public agencies can play an important role in improving air quality by limiting the amount of time engines are allowed to idle within their jurisdiction. Public agencies have the responsibility to lead the effort to improve air quality by adopting ordinances that are cost effective in reducing ozone precursor emissions and toxic air contaminants. This article is based on and derived from the Sacramento Ozone Summit Model Engine Idling Ordinance.
D. 
A study of idling exhaust emissions conducted by the U.S. Environmental Protection Agency (EPA420-R-02-025, October 2002) indicates that a typical 1980s-2001 model year truck operating on diesel fuel emits 144 grams per hour of nitrogen oxide and eight thousand, two hundred twenty-four (8,224) grams per hour of carbon dioxide emissions and consumes about 0.82 gallons of diesel fuel while idling.
E. 
TIAX, a consultant for the Sacramento Metropolitan Air Quality Management District, estimated idling exhaust emissions from heavy duty diesel trucks (HHDV), medium heavy duty diesel trucks (MHDV) and off road construction equipment to be 2.3 tons per day of nitrogen oxide emissions and .23 tons per day of reactive organic gas emissions. (Control Measures OFMS 52 and ONMS 45, April 2003). The maximum emissions reductions from full implementation of the Limitation on Engine Idling Ordinance in the Sacramento region was estimated to be 1.725 tons per day of nitrogen oxides emissions and .173 tons per day of reactive organic gas emissions (assuming a 75% compliance).
F. 
Under this article, a limitation on engine idling is established by the board of supervisors to discourage the idling of engines in the unincorporated Placer County.
