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: 4 r
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 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,
f
