Rule Title(s): Vanishing Oils and Rust Inhibitors

Date Submitted to ARB: November 13, 2009

If an Amended Rule, Date Last Amended (or Adopted): N/A

Is the Rule Intended to be Sent to the U.S. EPA as a SIP Revision? Yes No (If No, do not complete remainder of form)

District Contact: Mike Morris Phone Number: (909) 396-3282 E-mail Address: mmorris@aqmd.gov

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

The rule establishes a VOC limit of 50 g/l for vanishing oils and an initial limit of 300 g/l for rust inhibitors effective 

January 1, 2010. The VOC limit for rust inhibitors is further reduced to 50 g/l effective January 1, 2012. The rules 

also contains labeling provisions, record keeping requirements and applicable test methods.

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: 1.9 tons per day of VOC

Inventory Year Used to Calculate Changes in Emissions: 2006 Area Affected: South Coast Air Basin

Future Year Control Profile Estimate (Provide information on as many years as possible): 

There are approximately 12,000 facilities affected by the rule. The affected facilities are in the fabricated metal product 

manufacturing, machinery manufacturing, transportation equipment manufacturing, and petroleum and coal products 

manufacturing sectors in the AQMD. The 2006 baseline emissions inventory for this control measure is 5.47 tons per day 

and is expected to be reduced overall by 49.6 percent by 2012. The emission source categories affected by this rule 

account for 58 percent of the baseline inventory or 3.19 tons per day. The rule is expected to reduce those emissions by 

85 percent by 2012. The emission reductions for 2012 are estimated at 2.71 tons per day and expected to grow to 3.52 

tons per day by 2014 and to 3.75 tons per day by 2023.

Baseline Inventory in the SIP for the Control Measure: 5.47 tons per day of VOC in 2006

Emissions Reduction Commitment in the SIP for the Control Measure: 1.9 tons per day of VOC

Revised Baseline Inventory (if any): More than 3.19 tons from the affected categories, with the remainder 2.28 tons per 

day from additional categories.

Revised Emission Reduction Estimate (if developed): 2.71 tons per day of VOC 

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and 

planning.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: The rule requirements are expected to result in emission reductions of 2.71 tons per day of VOC. Additional 

reductions in VOC will help the Basin achieve state and federal RFP requirements and further progress toward attainment 

of ozone and PM10 standards.
