U.S. Environmental Protection Agency

What it is

The U.S. Environmental Protection Agency writes and enforces the federal chemical rules that decide what may be sold to consumers — the authority behind most "this was banned" claims on SafeMama's chemical hazard pages.

What it covers

TSCA risk evaluations and management rules (methylene chloride, chromated arsenicals, and related), FIFRA pesticide registration and restriction, the Lead Renovation, Repair and Painting rule, and household hazardous waste guidance. EPA's Safer Choice program is tracked separately in this registry as a certifier.

How to verify

Every action cited has a rule page on epa.gov carrying its effective date and scope. Where a rule phases in, the phase dates are on that page and belong in the citation.

How SafeMama uses it

EPA supplies the dated regulatory facts on garage and nursery chemical pages — methylene chloride strippers, CCA-treated lumber, consumer rodenticide formats. The editorial discipline is precision about scope: "banned from consumer sale effective [date]" is a different sentence from "banned," and the Hazard Map uses the first.

Limitations / conflicts

A restriction on new sale says nothing about product already in a reader's garage, which is exactly why several hazard pages exist. Risk evaluations can be revised, so dated citations are mandatory. No conflicts of interest: public-domain federal data.
