CA AB1400

Requires the Department of Toxic Substances Control to mandate that hazardous waste facility operators install monitoring devices at fence lines to detect potential releases into surrounding communities, except when local air pollution control districts impose substantially similar requirements.

Allows members of the public to request technical assistance grants to obtain information about pending hazardous waste facility permit applications, with grants mandatory if requested within one year of permit submission and discretionary thereafter.

Requires permit applicants to fund technical assistance grants and mandates the department post all new permit applications on its website with information about the grant application process.

Designates violations of these requirements as crimes, making this a state-mandated local program with no required state reimbursement under California Constitution Section 6 of Article XIII B.
