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

Amendments to Rule 4682 satisfy a control measure commitment included in both the Disrict's 2004 Ozone Plan 

and the 2007 Ozone Plan. The amendments establish more stringent VOC emission limits and controls for 

affected plastic foam product manufacturers.

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

 (CO) PM TAC (name):

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: Rule 4682 is intended to reduce VOC emissions from manufacturing polymeric foam and foam products by 

specifying material VOC content limits or emission control devices. Affected operators would have to comply with one of 

four rule requirments:

1. Demonstrate that they emit no more than 2.4lb of VOC for each 100 pounds of total material processed, or

2. Use a non-VOC blowing agent, or

3. Control all manufacturing emissions with an approved system and store the finished product in a controlled warehouse 

for 24 or 48 hours, or

4. Demonstrate that they release no more emissions than would have occurred if complying with option 3. Operators 

using VOC-limited beads and controlling 93% of the processing emissions are assumed to be in compliance with option 4 

unless the APCO determines additional controls are required.
