Fugitive particulate emissions (i.e., fugitive PM emissions that are a direct or proximate result of <br />mans activities) are likely to temporarily increase as a result of equipment operation and <br />material transport within and around the project area. Crushing, stockpiling and material hauling <br />activities during the dry summer months can potentially produce significant quantities of dust <br />and may adversely affect PMIO and PM2.5 levels locally. Regulations outlined in permits <br />required by APCD for sand and gravel operations and the associated equipment will continue to <br />apply. Operations are expected to continue at the current level. Therefore changes in air quality <br />are expected to be low. These impacts would be short-term in duration (the estimated timeframe <br />to mine in the Proposed pit is up to ten years) and relatively local, as mentioned in the previous <br />paragraph. <br />The No Action Alternative would result in no change in existing air quality for the life of the <br />permit. <br />a <br />1. The operator will comply with all State permits which relate to air quality. The operator <br />will implement those practices as such permits require, to control fugitive dust/particulate <br />emissions. These are listed below. <br />The project applicant is required to undergo APCD permitting review for both the gravel pit <br />itself, along with any portable or stationary processing equipment (excluding vehicles) which <br />operates within the facility. In order to receive final approval on APCD permits, the project <br />applicant must demonstrate compliance with visible emission (i.e., opacity) standards established <br />for the crushing, screening and conveying equipment, along with any permitted generator <br />engines and asphalt plants, by performing the necessary performance tests. All equipment <br />utilized at the project area would be properly maintained and operated in accordance with state <br />and federal pollution-control requirements, and APCD permit-specified fuel consumption and <br />aggregate processing limits for the facility. APCD representatives also perform routine <br />inspections at these types of facilities for permit compliance purposes. <br />In order to reduce or minimize wind erosion and fugitive dust emanating from the Proposed <br />Action, C and J will implement and monitor a Particulate Emissions Control Plan similar to the <br />existing plan contained in APCD Permit No. 99LP0697F for their existing Grandview Pit, which <br />adjoins the project area. Control measures required and currently included in the C& J Gravel <br />APCD permits for fugitive dust/particulate emissions control include: <br />• Adequate soil moisture must be maintained in topsoil and overburden to control emission <br />during removal. Watering shall be implemented if necessary. <br />• Topsoil and overburden stockpiles shall be compacted and revegetated within one year. <br />• Emissions from material handling (i.e. removal, loading, and hauling) shall be controlled <br />by watering at all times unless natural moisture is sufficient to control emissions. <br />• Vehicle speed on unpaved roads and disturbed areas shall not exceed a maximum of 15 <br />m.p.h. Speed limit signs shall be posted. <br />• Vehicle speed on haul roads shall be paved and watered as often as needed to control <br />fugitive particulate emissions. <br />• Finished product haul roads shall be paved and watered as often as needed to control <br />fugitive particulate emissions. <br />Grandview Gravel Pit Expansion Environmental Assessment 15
