I. GENERAL INFORMATION

District: South Coast Air Quality Management District

Rule No(s): 1144 Date adopted/Amended/Rescinded: July 9, 2010

Rule Title(s): Metalworking Fluids and Direct-Contact Lubricants

Date Submitted to ARB: January 7, 2011

If an Amended Rule, Date Last Amended (or Adopted): March 6, 2009

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 75 g/l for metalworking fluids, 130 g/l for Precision Metal Removal fluids and 

50 g/l for Direct-Contact Lubricants effective January 1, 2012. Military Specified Preservatives will be limited to 

340 g/l effective January 1, 2011. ASTM E 1868-10, with work instructions, is designated as the test method to 

determine VOC content. The rule also expands the prohibition of sale to newly applicable categories, provides a 

sell-through provision and contains labeling provisions, record keeping requirements and requires manufacturers 

and suppliers to submit annual quantity and emission reports for a three year period.

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 5.29 tons per day 

and is expected to be reduced overall by 67.5 percent by 2012. The adoption of the rule in 2009 will result in VOC 

emission reductions of 2.71 tons per day while this amendment will result in an additional 0.86 tons per day of VOC 

reductions.

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): 5.29 tons per day of VOC in 2006. The baseline was revised to reflect improved VOC

inventory data from a new thermogravimetric test method for determining the VOC content of metalworking fluids. The 

previous submittal for Rule 1144 in 2009 covered only a portion of applicable fluids (3.19 tons per day) but left the 

remainder unregulated until the new test method was validated. The new method was validated by ASTM, and EPA 

Region IX has found the method to be "acceptable for use in proposed amended Rule 1144". 

Revised Emission Reduction Estimate (if developed): 3.57 tons per day of VOC. 2.71 tons per day from the adoption of 

the rule in March 2009 and another 0.86 tons per day from this amendment in July 2010. 

Revised Emission Reduction Estimate (if developed): 3.9 tpd VOC Emissions, Annual Average (2014)

Revised Emission Reduction Estimate (if developed): 4.2 tpd VOC Emissions, Planning Inventory (2023)

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.

Sectioon (e) of the Rule.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: The rule amendments are expected to result in emission reductions of 0.86 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.
