Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

Rule 66.1 is a new rule designed to replace outdated Rule 66 – Organic Solvents. The new rule applies to 

miscellaneous coating and other operations emitting volatile organic compounds(VOC) that are not subject to 

other District rules regulating VOC emissions. Rule 66.1 will require all operations subject to it to be controlled 

by add-on air pollution control system uinless the VOC emissions are less than 5 tons/year or the VOC content of 

coatings complies with the specified limits. The rule also restricts the VOC content of surface cleaning materials 

to 50 g/l, or the VOC vapor pressure to 8 mm Hg at 20C and provides requirements for cleaning of coating 

application equipment, In addition, the rule includes the most recent VOC definition, establishes labeling and 

recordkeeping requirements for users, manufacturers and suppliers of VOC containing materials. The rule also 

contains exemptions for R&D, quality control and touch-up operations, limited exemptions for specialized 

processses, test methods and compliance schedule.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2
