NOTICE OF PUBLIC HEARING

PROPOSED AMENDMENTS TO THE RULES AND REGULATIONS OF

THE SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT

Proposed Amended Rule 1144 – Vanishing Oils and Rust Inhibitors

NOTICE IS HEREBY GIVEN that a public hearing on the matter of adoption of rules and 

regulations of the South Coast Air Quality Management District (AQMD), or the amendments 

thereto, will be held on June 4, 2010, in the Auditorium at AQMD Headquarters, 21865 Copley 

Drive, Diamond Bar, California, at 9:00 a.m. or later, at which time evidence will be taken and 

all interested persons will be heard by the AQMD Governing Board.

NOTICE IS FURTHER GIVEN that the AQMD is considering the amendment of Proposed 

Amended Rule 1144 – Vanishing Oils and Rust Inhibitors, and the objective of the rule is to 

reduce VOC emissions from metalworking fluids and lubricants used at industrial facilities 

during the manufacture and assembly of parts and products. The proposed amended rule will 

also prohibit the sale of metalworking fluids and direct-contact lubricants unless they meet 

applicable VOC limits, require containers to display the VOC content, require annual reporting 

of sales and provide exemptions for certain applications where deemed appropriate. The AQMD 

is also considering the use of two alternative thermogravimetric test methods for determining 

VOC content, SCAQMD Method 319 and ASTM E 1868 (with work instructions).. 

NOTICE IS FURTHER GIVEN that the AQMD has prepared the following supporting 

documents: 

 Proposed Amended Rule 1144 – Metalworking Fluids and Direct-Contact Lubricants, 

 Draft Staff Report for Proposed Amended Rule 1144, which includes the comparative 

analysis required by the California Health and Safety Code Section 40727.2, 

Environmental Assessment (CEQA) for Proposed Amended Rule 1144 and 

Socioeconomic Assessment for Proposed Amended Rule 1144.

The above documents are available on the AQMD website at
