Scheduling a Portable Inspection

The AVAQMD may conduct inspections of any PERP registered equipment at any time in order to verify compliance with the applicable requirements.  In accordance with PERP Program requirements, the AVAQMD is required to inspect all PERP engines and equipment units for which the AVAQMD has been designated as the "home district":

  • within one year of the issuance or renewal of the registration; and
  • on a three-year basis

The information below outlines the process to schedule an arranged inspection with the AVAQMD.

Provide Information to the AVAQMD

Owners and operators of registered engines or equipment units are required to contact the AVAQMD within 45 days of the initial issuance or renewal of a registration to arrange an inspection.

Receive Confirmation Email

Once an inspection has been scheduled, the AVAQMD will provide the contact specified in the request confirming the arranged date and time of the inspection. This form must be signed and returned to the AVAQMD before the inspection can take place.


In the event that an arranged inspection of a registered engine or registered equipment unit must be rescheduled due to unforeseen circumstances, the owner or operator is required to:

  • notify the AVAQMD of the cancellation no later than 72 hours prior to the scheduled inspection; and
  • reschedule the inspection no later than 90 days after the initially scheduled inspection.

Unreasonable Actions

The AVAQMD will make every reasonable effort to accommodate requested inspection dates; however, it is essential that the owner or operator put forth equal effort to ensure that the scheduled inspection occurs as planned.  This includes ensuring that the equipment identified in the inspection request is available at the location, on the date, and at the time specified in the request.  Further, if an "in-field" inspection has been arranged, the equipment must be in operation.

Any unreasonable actions on the part of the owner or operator that prevent the inspection from occurring within the specified time frame will be deemed a violation. Actions taken by the owner or operator that could be deemed "unreasonable" include, but are not limited to:

  • failing to respond to the district correspondences or other contracts made to schedule the inspection; 
  • failing to ensure that the registered engine or equipment unit is in operation for arranged "in-field inspections," where the district has provided advance notification to the owner or operator that the registered engine or equipment unit is required to be observed in operation.
