Enforceable Consent Agreements (ECAs)

EPA Agreement Requires Siloxane Environmental Testing Data from Chemical Manufacturers

April 3, 2014 - EPA has entered into an Enforceable Consent Agreement with five manufacturers of octamethylcyclotetrasiloxane (also called D4), which is widely used as a chemical intermediate and component of personal care products. Learn more. Read the Federal Register notice.

Overview

The formal ECA process began in 1992 when EPA publicly announced an initiative to encourage members of the U.S. chemical industry to submit testing offers to conduct needed testing under public ECA procedures on chemicals for which EPA had not yet issued final TSCA Section 4 test rules.

Creation of an ECA requires the development of formal agreement between EPA, industry, and other interested parties on what testing must be conducted.

ECAs allow greater flexibility in the design of the testing program (e.g., test methods can be negotiated).

EPA is not required to make statutory TSCA Section 4 "findings" for ECAs.

It usually takes less than a year for testing to begin on chemicals subject to ECAs.

For all chemicals subject to ECAs, TSCA Section 12(b) export notification by industry is still required.

ECA on Octamethylcyclotetrasiloxane (D4)

EPA has entered into an Enforceable Consent Agreement with five manufacturers of octamethylcyclotetrasiloxane, which is widely used as a chemical intermediate and component of personal care products. The EPA will require testing for the chemicalís presence in several environmental media.

Under the terms of the ECA, the signatory companies have agreed to collect and analyze samples from environmental media around wastewater treatment plants (WWTP) that treat D4. WWTP influent, WWTP effluent, and WWTP biosolids. In addition, downstream surface water, sediment, and biota will be tested. The testing program will be conducted over a one year period. The information gathered by the ECA will be used in conjunction with other available data to assess exposures and risks due to environmental releases from D4. Read the Federal Register notice.

Materials related to this ECA can be found in the docket: EPA-HQ-OPPT-2012-0209.
