Sec. 9.33.010 - Findings and Declarations.¶
The Board of Supervisors of the County of Mendocino ("County") finds and declares as follows:
(A) Open burning of nonvegetative matter releases into the atmosphere unacceptable levels of pollutants, toxics, and other regulated substances which can include: respirable particulates, carbon monoxide, heavy metals, acids, oxides of nitrogen and sulphur, cyanide, and many organics including PCBs, hydrocarbons, furans, dioxins, and aldehydes. This burning produces ash frequently laden with toxics including heavy metals. The smoke and ash created by such fires exposes County residents to airborne contaminants because of the County's basin topography and frequent inversions. Significant potential for soil and water contamination would result from the inappropriate and illegal disposal of ash from such fires.
(B) Open burning of paper contributes to the County's air pollution problem because papers are being burned which contain a complex collection of chemicals. Additionally, burning of household wastes, construction wastes, commercial operations and other wastes, such as tires and petroleum products, are polluting the County's air.
(C) The County has a duty to assure clean air, and it is in the interest of the health, safety and welfare of all who live, work and do business in the County that air pollution be reduced.
(D) This Chapter is consistent with the legislative intent and findings in the Mulford-Carrell Air Resources Act (Division 26 of the Health and Safety Code, at Section 39001, et seq.)
(Ord. No. 3746 Sec. 1 (part), adopted 1990.)
