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 ' 'Fugifive Dusf Control Planby. 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 wherePM 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 part 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. Very truly yours, RRY HERMAN Planning & Development Director JH:WHN:bjs Attachment Tc"�� ^� MAILING ADDRESS - P.O.. BOX 1504 - 'LA OUINTA, CALIFORNIA 92253 �0 f Ir ' is .
