Comment Period - MADLs for Atrazine, Propazine, Simazine, 2,4-Diamino-6-Chloro-S-Triazine (DACT), Des-Ethyl Atrazine (DEA), and Des-Isopropyl Atrazine (DIA)
NOTICE IS HEREBY GIVEN that the Office of Environmental Health Hazard Assessment (OEHHA) proposes to adopt Proposition 65 Maximum Allowable Dose Levels (MADLs) for oral exposure to atrazine, propazine, simazine, 2,4‑diamino‑6‑chloro-s-triazine (DACT), des-ethyl atrazine (DEA), and des-isopropyl atrazine (DIA) that induce reproductive toxicity by amending Section 25805(b) of Title 27 of the California Code of Regulations.
The proposed oral MADLs are 100 micrograms per day for each of the six chemicals. The MADLs are based on data for atrazine, which is representative of all six of the identified chemicals.
The rulemaking for adoption of these MADLs been delayed because the listing of these chemicals under Proposition 65 was challenged in a legal proceeding[4]. This regulatory action will not be finalized until atrazine, propazine, simazine, DACT, DEA, and DIA are listed under Proposition 65 as known to the state to cause reproductive toxicity (developmental and female reproductive endpoints). The listings are based on formal identification of these chemicals by the US Environmental Protection Agency (US EPA) as causing developmental and female reproductive toxicity. The US EPA is a body recognized as authoritative for the listing of chemicals as known to cause reproductive toxicity under Proposition 65 (Section 25306(l)).
