Any unpaved construction exit/entry point along existing paved roads/areas shall be improved as.set forth in the FDCP. Wet sweeping/flushing. (dry -sweep not permitted) of soil accumulations from all paved areas shall be conducted daily, and kept damp during construction hours until so removed. 12. All on -site traffic on unpaved roads shall be limited to 15 MPH as stated in the FDCP application. Signs shall be posted at all entries and along all unpaved access and travel ways at minimum 300-foot intervals. Size and height of the signs shall be appropriate for their respective locations, and shall not be posted on any adjacent private properties. Project site superintendent(s) and any security personnel shall be responsible for enforcing this requirement-. 13. All unpaved construction access and travel ways within the site shall be prepared for traffic prior to commencing grading activities and kept watered down and compacted to retain moisture content during all construction traffic/activity, including building construction. At a minimum, temporary construction travel ways shall be improved to a 20 foot width. All unpaved road lengths shall be watered each day, prior to and at intervals during any traffic activity, and at the end of the day after all activity has ceased. All track - out shall be removed as per Condition #10. 14. FDCP 99-75, indicates 26,885 CY of export material. All on and off -site soil transport and.stationary storage piles shall be sufficiently stabilized, watered down and/or covered as required. Minimum freeboard shall be as established by the Public Works Department. Any storage areas shall be. routinely watered and chemically stabilized after borrow activities to mitigate airborne dust. Off site spreading areas shall be subject to requirements of this FDCP, and any such areas outside the City limits shall have the appropriate agency and property owner authorizations (see Cond. 3). 15. All on -site temporary employee facilities (sales, construction, equipment storage/staging, etc.) shall be provided with paved, compacted or otherwise stabilized parking and access during their operation, with those improvements to be constructed/installed to the applicable Public Works Department standards. This requirement shall apply to any approval for such facilities under a minor use or other permit process. 16. If approved on -site roadways/parking areas are constructed to ultimate design prior to completion of construction activities, then: traffic and parking shall be limited to those paved areas as feasible. No vehicular parking or traffic of any kind is permitted on or over any previously stabilized or undisturbed soil -areas. 17. Disturbed but inactive development areas subject to additional grading or building construction within 30 days of completion of the initial disturbance, shall be watered daily in conjunction with watering of access roads and developing areas, unless an appropriate dust suppressant defined in Chapter 6.16 of the LQMC and approved by the California Water Quality Control Board, Region 7, or as specified in the FDCP, has been applied in lieu. All disturbed areas where no further grading, construction or other land disturbance will occur for at least 30 days, shall be stabilized with dust suppressant specified in the FDCP, or by establishment of vegetation, no later than four days after completion of the initial grading. These areas shall be staked, posted or otherwise restricted in order to prevent any access on or across them. 18. Construction activity associated with this project will occur during potential seasonal high wind activity in the Coachella Valley, and is located within an identified blowsand hazard zone. All active graded areas shall be watered daily at appropriate intervals. At least one water truck shall be stationed on -site on weekends and holidays. All security personnel shall be alerted to the need for dust control and instructed to monitor graded areas for wind -generated dust as part of their routine duties. 19. On Sundays, holidays and other non -construction days, personnel shall be on - call for emergency watering in the event of high winds. Additionally, during all grading operations, an appropriate individual shall be assigned to monitor wind conditions. This shall be done by utilizing wind forecasts available from the South Coast Air Quality Management District (SCAQMD). Wind forecasts can be obtained by dialing 1-800-CUT-SMOG and following menu options for Air Quality and High Wind and Dust. The individual shall access this information daily, prior to commencing construction activities. In the event.that winds are forecast to exceed 25 MPH (403.1 High Wind Day), all construction activities and .on -site traffic shall be closely monitored to insure compliance with the FDCP. Said individual shall coordinate with the assigned inspector on adequacy of current dust control measures and any additional measures potentially necessary. If such measures are ineffective in minimizing airborne dust, then grading activity shall cease until high wind conditions subside or other effective dust control measures are employed to allow grading to continue. �vv 78-495 CALLS TAMPICO — LA QUINTA, CALIFORNIA 92253 - (619) 777-7000 FAX (619) 777-7101 May 10, 1994 TO: ALL ACTIVE AND PROSPECTIVE DEVELOPERS/BUILDERS IN THE CITY OF LA QUINTA RE: PM 10 PROGRAM REPORTING REQUIREMENTS FOR FUGITIVE DUST CONTROL PLANS Dear Developer/Builder: The Coachella Valley PM 10 Program has been in its implementation phase since December, 1992. Among the required control measures was the enactment by Valley cities of dust control ordinances which require builders to implement dust control actions during construction, demolition and paving activities. In conjunction with City staff members, we ask your help with the reporting requirements. A significant aspect of the PM 10 Program is the need to report statistical information to the Federal Environmental Protection Agency via the South Coast AQMD and the State of California Air Resources Board. In response to this requirement, a Dust Control Reporting Form has been created, a copy of which is attached. It is requested that if any project developers have amounts to report for any PM 10 mitigation, these forms must be filled out. This form is intended to supplement Attachment "B" of the Fugitive Dust Control Plan by providing specific cost figures related only to dust control measures. The South Coast AQMD has requested that the retroactive operative date be January 1, 1993, for reporting purposes. This means that each jurisdiction is requested to review projects since that date where PM 10: control measure expenses have been incurred by developers, whether or not they have been incorporated as. part of a Dust Control Plan, and forward this data to CVAG as soon as practical. Your cooperation in completing these forms as pan of the grading permit procedure will help assure that the Coachella Valley and the development community as a whole receive deserved credit for the effort to attain Clean Air Act standards for PM 10.
