PROPOSED AMENDED RULE 1144 VANISHING OILS, METALWORKING 

FLUIDS AND DIRECT-CONTACT LUBRICANTSRUST 

INHIBITORS

(a) Purpose 

The purpose of Rule 1144 is to reduce volatile organic compound (VOC) 

emissions from the use of vanishing oilsmetalworking fluids and direct-contact 

lubricants and rust inhibitors at industrial facilities. 

(b) Applicability 

The rule applies to all persons who use metalworking fluids and direct-contact 

lubricants vanishing oils and rust inhibitors that come into direct contact withon

products and parts during manufacture and assembly; and all manufacturers and 

suppliers who supply, sell, or offer for sale metalworking fluids and direct-contact 

lubricants vanishing oils and rust inhibitors for use at industrial facilities. This 

rule shall apply to all VOC containing fluids used for metal workingmetalworking

including , metal removal, metal forming, metal treating or lubricating operations 

where the metalworking fluid or direct-contact lubricant vanishing oil comes into 

direct contact with products and parts including, but not limited to, blanking, 

broaching, coining, cutting, drilling, drawing, forming, forging, grinding, heading, 

honing, lapping, marquenching, milling, piercing, quenching, roll forming, 

rolling, stamping, tapping, threading, turning and wire drawing. The rule also 

applies to VOC containing fluids used for metal protection, including rust and 

corrosion prevention and inhibition, during the manufacture and assembly of 

products and parts. The provisions of this rule shall not apply to repair, 

maintenance or research operations. 

(c) Definitions 

For the purpose of this rule, the following definitions shall apply:

missiles. 

(2) DIRECT-CONTACT LUBRICANT is a fluid that comes into direct 

contact with the product or part during manufacturing or assembly and is 

used to reduce heat and friction and to prolong the life of machine tools 

and machinery. A direct-contact lubricant is not a metal forming fluid and

(3) EXEMPT COMPOUND is as defined in Rule 102. 

(4) GRAMS OF VOC PER LITER OF MATERIAL is the weight of VOC per 

volume of material and can be calculated by the following equation: 

Grams of VOC per liter of material = 

WW W s w es − −

Where: Ws = Weight of volatile compounds in grams 

Ww = Weight of water in grams 

Wes = Weight of exempt compounds in grams 

Vm = Volume of material in liters 

(5) LAPPING is a manufacturing method that employs particles of an 

abrasive material, suspended in a liquid carrier, between rotating plates. 

(6) MANUFACTURING is the use of tools and labor to make things for sale.

interface to facilitate the flow of metal over the tool and to extend the life 

of the tool. Common metal forming operations include, but are not limited 

to, blanking, coining, drawing, forming, forging, heading, piercing, roll 

forming, stamping and wire drawing. 

(8) METAL PROTECTING FLUID is fluid that inhibits or prevents the 

corrosion of metal surfaces. It is applied independently of any other 

metalworking, lubricating or cleaning application.

(9) METAL REMOVAL FLUID is a fluid used at the tool and workpiece 

interface to facilitate the removal of metal from the part, cool the part and 

tool, extend the life of the tool, and to flush away chips and debris. 

Common metal removal operations include, but are not limited to, 

broaching, cutting, drilling, grinding, honing, lapping, milling, tapping,

and threading and turning.
