CONSTRUCTION EMISSIONS MITIGATION As identified above, construction activities are not anticipated to cause dust emissions to exceed SCAQMD CEQA thresholds. Nevertheless, mitigation through enhanced dust control measures is recommended for use because of the non- attainment status of the air basin. Recommended mitigation includes: Fugitive Dust Control • Apply soil stabilizers or moisten inactive areas. • Prepare a high wind dust control plan. • Address previously disturbed areas if subsequent construction is delayed. • Water exposed surfaces as needed to avoid visible dust leaving the construction site (typically 3 times/day). • Cover all stock piles with tarps at the end of each day or as needed. • Provide water spray during loading and unloading of earthen materials. • Minimize in -out traffic from construction zone • Cover all trucks hauling dirt, sand, or loose material and require all trucks to maintain at least two feet of freeboard • Sweep streets daily if visible soil material is carried out from the construction site Similarly, construction activity ozone precursor emissions (ROG and NOx) are calculated to be below SCAQMD CEQA thresholds. However, because of the non - attainment for photochemical smog, the use of reasonably available control measures for diesel exhaust is recommended. Combustion emissions control includes: Exhaust Emissions Control • Utilize well -tuned off -road construction equipment. • Establish a preference for contractors using Tier 3 or better heavy equipment. • Enforce 5- minute idling limits for both on -road trucks and off -road equipment. OPERATIONAL EMISSIONS MITIGATION Operational emissions would not exceed their respective SCAQMD significance thresholds with the following mitigation measure: • Utilize gas hearths rather than wood burning fireplaces for any residential use. 19x1 a 1- 5, AQ
