Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

Under existing Rule 1186, street sweeper manufacturers are required to certify their equipment “pick-up efficiency” is 

at least 80 percent. It has been more than five years since any certification testing has been conducted and there 

was a need to ensure that the overall performance of the sweepers can still be demonstrated in the event the 

manufacturer changes parts suppliers and/or modifies any sweeper specification from that on the originally 

configured model. The amended rule requires submission of data to demonstrate that the sweeper performance has 

not been affected by these changes and also establishes a process that aftermarket parts suppliers may qualify to 

sell replacement parts while maintaining the original equipment certification.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

 (CO) PM TAC (name):

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission 

factor(s) and other information. Attach calculation sheet showing how the emission information provided below was determined.

Net Effect on Emissions: Increase* Decrease** N/A

Emission Reduction Commitment in SIP for this Source Category: N/A The amendments are administrative in nature and 

do not significantly affect air quality or emission reductions. However, the amendments will help safeguard emission 

reductions previously assumed by ensuring that changes to sweepers do not affect the equipment’s potential for PM10 

reductions.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment

Discussion: As mentioned, the amendments are administrative in nature and will not significantly affect air quality or 

emission reductions. However, the amendments will help safeguard emission reductions previously assumed by ensuring 

that changes to sweepers do not affect the equipment’s potential for PM10 reductions.
