CALIFORNIA EPA Issues SUD
for Crystalline Silica in Interior Flat Latex PAINT
On Dec. 26, California’s Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) issued a safe use determination (SUD) to NPCA for crystalline silica in interior flat latex paints containing six percent crystalline silica, or less, with diatomaceous earth as the sole source of crystalline silica, under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). OEHHA tendered its determination based on the results of a screening level assessment using testing data submitted by NPCA on the amounts of respirable crystalline silica produced from the normal use of interior flat latex paints, pursuant to NPCA’s application for a SUD.
OEHHA’s notice explaining its analysis in reaching its final evaluation can be found at the following web site: www.oehha.ca.gov.
