Overview

 Background

 California Toxic Air Contaminant Identification and 

Control Program

 2000 Airborne Toxic Control Measure for Emissions of 

Chlorinated Toxic Air Contaminants from Automotive 

Maintenance and Repair Activities

 Consumer Product Regulations

 Consumer Products and Trichloroethylene

 Summary

 References and Contacts
California Toxic Air Contaminant Identification 

and Control Program

 Established pursuant to Assembly Bill (AB) 1807

 Trichloroethylene (TCE) identified as a toxic air 

contaminant (TAC) in October 1990

 No Board-specified threshold exposure level for TCE

 Airborne Toxic Control Measure (ATCM) must reduce 

emissions to lowest level through application of Best 

Available Control Technology for Toxics (T-BACT)
2000 ATCM for Emissions of Chlorinated Toxic Air 

Contaminants from Automotive Maintenance and 

Repair Activities

 Reduces emissions of perchloroethylene (Perc), 

methylene chloride (MeCl), and trichloroethylene 

(TCE) from the following products used in automotive 

maintenance and repair (AMR):

 Brake cleaners

 Carburetor cleaners

 Engine degreasers

 General-purpose degreasers
2000 ATCM for Emissions of Chlorinated Toxic Air 

Contaminants from Automotive Maintenance and 

Repair Activities (contd.)

 AMR products manufactured for sale in California 

cannot contain Perc, MeCl or TCE as of June 30, 2001

 Products manufactured prior to June 30, 2001 were 

allowed to be sold until June 30, 2002

 Products were allowed to be used by AMR facility 

owners and operators until December 31, 2002
What Are Consumer Products?

 Chemically formulated products

 Used by household and institutional consumers

 Types of products include:

 Cleaning Products 

 Aerosol Paints

 Antiperspirants and Deodorants

 Household Pesticides

 Personal Care Products 

 Automotive Specialty Products
Consumer Products Regulatory History

 Milestone Rulemakings

 November 1989: Antiperspirants and Deodorants Regulation

 August 1990: Statewide Consumer Products Regulation

 February 1995: Aerosol Paints

 Milestone Accomplishments

 TAC reductions over 13 tons per day

 VOC reductions of 218 tons per day by 2015

 GHG reductions of ~0.23 MMT of CO2 equivalents per year
Authority to Regulate

 Toxic Air Contaminant (TAC) Emissions:

HSC 39650 et seq.

 Greenhouse Gas (GHG)Emissions: 

HSC 38500 et seq.

 Volatile Organic Compounds (VOC): 

HSC 41712
Consumer Products Regulation: Phase 1 (1990)

 Contains an ozone depleting provision

 Prevents manufacturers from reformulating with 

HCFCs and TCE due to ozone depleting potential 

greater than zero

 Allows compliant products already containing ozone 

depleting compounds to retain formulation
Consumer Product Regulation: 1996 Rulemaking

 Used the risk assessment performed under the 

California Toxic Air Contaminant Identification and 

Control Program as a basis for prohibiting the use of 

TCE and other Toxic Air Contaminants in 

approximately 90 consumer product categories

 Product categories for regulation identified through 

industry survey and review of technical literature
