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 respon'se.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.
r Your cooperation in -'completing these forms as part of the grading permit procedure will help assure
J that the Coachella° Valley and the development community as a whole receive deserved credit for the
effort to attain Clean Air Act standard_ s for PM 10. -
Very truly yours,
t
