3. Although the Proposed Regulation VIII has not been approved yet by the San Joaquin County APCD, once adopted, the applicant shall conform to the requirements specified within it to assure that appropriate steps have been taken to control dust. The proposed requirements include demonstrating at least an overall average 75 percent reduction from uncontrolled PM-10 emissions, preparing a dust control plan to be approved by the APCD, performing surface surveys for moisture analysis, and performing visible emission tests or evaluations. The applicant shall maintain proper records of the dust control plan which shall be available for scheduled and unscheduled inspection by the County and the APCD. 4. To minimize emissions from the loaders and other equipment used on site, low- sulfur fuel should be used, and the equipment should have routine maintenance and tuning performed biweekly. Noise 1. The loader, haul trucks, and any other heavy equipment shall be fitted with state-of-the-art noise shielding and muffling devices. Such devices may reduce noise from individual pieces of machinery by up to 10 dBA over noise without noise abatement devices (U.S. Environmental Protection Agency, 1971). 2. Noise generating activities shall be avoided between 7 p.m. and 7 a.m. when they would be most disruptive. Excavation activities shall be prohibited during weekends and holidays, except in emergency situations such as natural disasters. 3. Noise level monitoring should be conducted at the nearest residences when extraction activities approach approximately 300 feet of the bluff. Noise monitoring shall be conducted in accordance with the County Noise Ordinance (Chapter 16, Section 9-3800). If monitoring indicates that noise levels exceed 65 db Ldn at the property line, then further noise mitigation should be implemented. This could include not allowing any extraction activity beyond the point at which the noise effects occur. Mitigation shall also be required if noise monitoring indicates an increase of approximately seven dBA or more over ambient levels at the nearest residence and the resident complains about noise levels. Public Facilities No impacts to Public Facilities would be anticipated from the proposed activity. As such, no mitigation measures would be required. Land Use Use of proposed site for resource extraction would be a long term use that would, without mitigation, be incompatible with the existing residential and commercial uses, and residentially zoned areas within the town of Clements, due to noise and visual impacts. These impacts could be mitigated to less than significant levels by
