Industrial Cleaning Solvents

The Pennsylvania Department of Environmental Protection has proposed new regulations based on the EPA September 2006 Control Techniques Guidelines (CTG) for Industrial Cleaning Solvents. The CTG is intended to cover all industrial cleaning operations, that are not already regulated elsewhere.

The proposed regulations are intended to control VOC emissions from industrial cleaning operations and will potentially impact a large number of small businesses in Pennsylvania.

The ICS category includes a variety of products used to remove contaminants such as adhesives, inks, paint, soil, oil and grease.  Types of cleaning activies include operations such as parts cleaning, spray gun cleaning, spray booth cleaning, large and small manufactured components cleaning, eqiupment cleaning, line cleaning, tank cleaning and floor cleaning.

In the proposed regulations, compliant solvents must meet one or both of the following VOC limits:

• A VOC content less than or equal to 0.42 pounds of VOC per gallon (50 grams of VOC per liter of industrial cleaning solvent as applied.

• A VOC composite vapor pressure equal to or less than 8 mm mercury at 68oF (20oC) as applied.

Pennsylvania DEP accepted comments on this proposed rulemaking from 6/17/17 to 8/21/17.  Comments that were submitted to DEP can be found here.
