OPPT workplan risk assessment Methylene Chloride (dichloromethane; CASRN 75-09-2) and N-Methylpyrrolidone (NMP; CASRN 872-50-4).
Impact/Purpose:
EPA anticipates issuing draft risk assessments for public review and comment as they are completed. At the conclusion of the review process, if an assessment of specific uses indicates significant risk, EPA will evaluate and pursue appropriate risk reduction actions, as warranted. If an assessment indicates no significant risk, EPA will conclude its current work on assessment of those specified targeted uses of that chemical. Over time, additional chemicals will be added to the work plan as more data are developed and more chemicals screened.
Description:
These assessments will focus on the use of DCM and NMP in paint stripping. NMP exposures scenarios for this use result in inhalation and dermal exposure to consumers and workers. The low concern for environmental effects of NMP will be discussed in the assessment. In the case of DCM, there are human health concerns for both cancer and non-cancer effects. This DCM assessment of paint stripping uses will focus only on inhalation exposure to consumers and workers. The low concern for environmental effects of DCM will be discussed in the assessment.
