Public Hearing: Dec. 2, 2020 Public Workshops Draft Amendments

The Division of Air Quality is amending Section 33.0 (Solvent Cleaning and Drying) of the Control of Volatile Organic Compound Emissions Regulations (7 DE Admin. Code 1124 and Appendices).

Solvent cleaning is the process of using solvents to remove contaminants from various plastic, metal or other substrates (surfaces). The following businesses may use solvent cleaning and drying in their operations: vehicle sales and servicing locations; machine shops; and manufacturers and servicers of electronic, pharmaceutical, aerospace, and other mobile equipment.

The objective of these amendments is to adopt certain provisions from the Ozone Transport Commission 2012 model rule for solvent degreasing. These amendments will reduce emissions of volatile organic compounds from solvent cleaning operations.

This regulatory amendment process started with DNREC Start Action Notice 2019-05.

Note: The final regulation titled Control of Volatile Organic Compound Emissions, Section 33- Solvent Cleaning and Drying, has been published in the Aug. 1, 2021 Delaware Register of Regulations, and was effective Aug. 11, 2021.

DNREC has prepared an example placard (Batch Cold Cleaning Machine Workplace Practices) that facilities can post.
