### Subpart A—General

§ 1400.1 Purpose.

Stationary sources subject to theChemical Accident Prevention Provisions of 40 CFR part 68 are required to analyze the potential harm to public health and welfare of hypotheticalchemical accidents and submit the results of their analyses to the U.S. Environmental Protection Agency as part of risk management plans.

This part also restricts dissemination of that information by government officials.

(j) Off-site consequence analysis (OCA) data elements means the results of theoff-site consequence analysis conducted by a stationary source pursuantto 40 CFR part 68, subpart B, when presented in a format different than sections 2 through 5 of a risk management plan or any Administrator-created electronic database.
